The presence of mechanical spindle feed on machines, with manual control of work cycles.

Allows processing of parts in a wide range of sizes from various materials using tools from high-carbon and high-speed steels and hard alloys.

The machines are equipped with a device for reversing the main motion electric motor, which allows them to cut threads using machine taps while manually feeding the spindle.

The machine has high rigidity, strength of working mechanisms, drive power and a wide range of cutting speeds and feeds, allowing the use of cutting tools equipped with carbide. The presence of an electric reverse, controlled both automatically and manually, provides the ability to cut threads with manual approach and withdrawal of the tap.

The design of the vertical drilling machine model 2A135 provides for automatic switching on of the feed movement after the cutting tool is quickly brought to the workpiece and automatic switching off of the feed when the specified drilling depth is reached.

The specified drilling depth for blind holes is ensured by a special stopping mechanism with a stop. This mechanism is also a safety device that protects the feed mechanism from damage due to overload.

The machine spindle is mounted on precision rolling bearings. The lower support consists of a radial ball bearing of class AB. The upper support has one class B ball bearing.

The plant provides the possibility of changing the drive pulleys of the belt drive, which allows you to set the limits of the spindle speed in accordance with the technological tasks.

To reduce auxiliary time on the machine model 2A135, it is possible to turn the feed on and off using the same steering wheel that manually moves the spindle quickly.

Node design

The main load of the 2A135 vertical drilling machine is carried by a column and a slab. But thanks to the housing design and large mass, loads and vibrations are dampened, and rigidity increases.

Spindle

The spindle unit is a rigid structure, therefore, to increase the processing accuracy, precision bearings are installed in it. Its design allows you to perform the following actions:

• turning on the approach after performing a quick approach (automatically);
• turning off the supply upon reaching the set processing depth;
• manual movement is carried out by the steering wheel;
• The steering wheel is equipped with an automatic drive activation device.

Cooling

The cooling system for the tool and workpiece is similar to those installed on other vertical drilling machines. The container is the internal cavity of the mounting plate. A pump is mounted on it, and along the body there is a distribution of pipelines with taps that regulate the supply of coolant.

Cooling system design for vertical drilling machine 2A135

Gearbox and feeds

The combined gearbox and feeds form all the working movements of the machine. The main, main movement is the circular rotation of the spindle with the working tool. The rotation from the electric motor is transferred to the gearbox via a belt drive. On the spindle, rotation at a given speed is generated by two sets of gear blocks.

Auxiliary movement – ​​movement of the tool. Rotation is removed from the shaft that transmits rotation to the spindle. The selection of feed and its activation is carried out by clutches. According to the diagram, 12 speeds are possible, but due to the fact that two are combined, the result is 11.

The device of the gearbox of the drilling machine 2A135

The spindle head has manual movement to increase the distance between the table plane and the end of the spindle. This allows you to install large parts. Rotation of the handle sets in motion a gear that moves along a rack. This moves the spindle head.

Performing various types of work on the unit

The device allows you to perform drilling operations. The technology for performing this operation on a machine requires the use of a drill with a larger diameter than the diameter of the jumper on another drill. With this approach, the axial drag force becomes significantly smaller.

When drilling a product, the jumper should cut into it and not squeeze out the metal. In the second case, there is a serious increase in axial resistance.

The vertical drilling machine has a countersinking function. Only specific types of products are subject to such an operation:

• stamped;
• forged;
• having holes inside in the shape of a cone or cylinder;
• cast.

Deployment on the unit is carried out in two stages:

1. at the first stage, a cylindrical hole is drilled in the workpiece, after which it is subject to processing with a stepped conical countersink;
2. at the second stage, the metal product is first rough processed with special reamers, after which finishing reaming is performed by installing a conical reamer with smooth edges.

Operation and repair

The operation of the device begins with its column, which performs the function of fixing it on the floor surface. The column is made of cast iron. The work table, which is attached to the column, moves together with the drilling head using a manual drive.

The movement occurs along the column itself. The plate, which plays the role of the base, has an internal cavity in which a special cooling liquid is located. A sump tank is also installed there. An electric pump system is attached to the upper part of the base plate, with the help of which, during operation of the machine, coolant is supplied to the workpieces.

The feed box is installed separately in a special housing located in the working head.

The second main technique for operating the 2n135 machine involves operating the feeder. It includes the following elements:

• 2 couplings, one of which is ratcheting, the other is overrunning;
• steering wheel for control;
• rack-and-pinion gear located on a horizontal shaft;
• worm-gear;
• limba having divisions.

Limba
Thanks to the feed device, the scheme of working with the machine implies a wide range of actions:

• switching off, switching on feed;
• cutting threads on the product itself using the manual feed method;
• spindle retraction upwards from the workpiece;
• bringing the processing tool to the product manually;
• performing advance feed manually.

The mechanism works as follows: the jaw clutch is driven by a rotating handwheel. The clutch then drives a gear, which is connected to a rack, which feeds the spindle.

All this is done manually. When the processing tool impacts the workpiece, the gear rotates. Movement occurs along the axis of the shaft until the moment when the cams of the coupling itself are opposite each other. At this moment the clutch turns 2000.

In cases where the machine was repaired, it is necessary to check its components

It is important to ensure that there are no traces of corrosion on the device. After repair work, the unit runs idle, and the cutting tool is not installed

During a test run, the operation of the device is checked against the data in its technical passport.

Unit design

The design of the drilling machine includes:

• bed;
• table;
• feed unit;
• plate;
• electric motor;
• spindle;
• speed block;
• a handle that moves the surface vertically;
• handle for manual spindle feed.

The key element of the feed mechanism is the feed box. The gearbox is driven by a gear. It is located on the spindle splines. This gear meshes with a double gear, which is located on the spindle axis. Thanks to the action of the mechanism, the rollers of the machine are set in motion.

For protective purposes, a clutch is provided in the feed block. It protects the unit from failure when the system is overloaded. The actuated clutch helps cut off the mechanical feed.

The purpose of the plate is wide. It stores the coolant supplied to the working element of the device. The liquid is stored in a special tank built into the stove. The base plate itself is made of cast iron. An electric pump is installed on the plate, communicating with the coolant reservoir through tubes.

The amount of liquid supplied to the working element of the machine is regulated using special taps installed on the tubes.

The cooling system of the unit constantly needs to clean the sump. Various waste contaminants periodically accumulate in it, interfering with the normal operation of the equipment. It is necessary to clean the sedimentation tank once a month or more often.

Feeding mechanism - operating principle

The design of the feed mechanism of the 2N135 machine, which is the most important working part of the drilling head, consists of the following main elements:

• steering wheel;
• worm gear;
• two clutches – overrunning and ratcheting;
• limb with divisions;
• rack and pinion located on the horizontal shaft.

The feed mechanism allows you to perform a number of technical operations during the processing of the workpiece:

• perform feed advance in manual mode;
• cut internal threads in the workpiece using manual feed;
• bring the working tool to the workpiece manually;
• turn the supply on and off;
• move the spindle upward away from the workpiece.

Feed box for vertical drilling machine 2N135

Despite the relative complexity of the feed mechanism design, the principle of its operation is quite simple. Due to the rotation of the steering wheel, movement is transmitted to the cam clutch, which, in turn, through the half-coupling-holder, engages the gear shaft that is connected to the rack (the rack provides vertical movement (feed) of the spindle in manual mode).

At the moment when the tool touches the workpiece, the gear shaft begins to rotate, but this rotation cannot be transmitted by the teeth of the cam-type coupling, as a result of which the half-coupling cage begins to move along the shaft axis until the clutch cams are located opposite each other . Only at this moment does the coupling rotate 200 (rotation to a larger angle is impossible, since the structural elements of the coupling itself will not allow this).

The design of the half-coupling includes a double-sided ratcheting disk, which, when it moves, imparts movement to a gear wheel connected by a worm gear. The movement of this coupling, accordingly, leads to rotation of the worm and longitudinal movement of the rack shaft. This is how the mechanical feed of the spindle is ensured, which can be surpassed if you continue to rotate the steering wheel.

The passport for the machine also stipulates the possibility of manual movement of the working head. For this purpose, the box contains rack and worm pairs, which can be used if you turn off the mechanical feed using the steering wheel.

Where is the 2r135f2 CNC drilling machine used?

The machine in question is used to regulate the process of rectangular machining and positioning. The program carrier is a punched paper tape with eight tracks. The machine is equipped with a digital display; up to 15 adjustments per tool length can be entered.

The machine has a closed system in which the BS155A selsyn acts as sensors. The table and slide are positioned with an accuracy of up to 0.02 mm, digital display and movement assignments have a resolution of up to 0.01 mm. There are a total of 3 controllable coordinates, 2 of which can be used simultaneously.

Adjustment and setup of drilling machine 2A135

After installing the machine at the workplace, cleaning, filling with oil and lubricant, connecting to the electrical network, checking operation at all speeds and feeds, no adjustment is required. Setting up the machine consists of installing the table and bracket in the positions required for operation and clamping the bracket wedge, as well as setting the speed and feed rates.

The clearances in the spindle bearings are selected through a window on the front wall of the bracket, closed with a lid. When adjusting, you need to turn the spindle so that the adjusting nut screw is in the window, then, loosening the screw, tighten the nut and tighten the screw again.

The drilling depth is set using a dial as follows: by rotating the cross steering wheel towards you, lower the spindle until it comes into contact with the workpiece. We unscrew the screw of cam 17 (see the figure for turning off the feed and cam 18, turn until the edge of cam 17 coincides with the dial division corresponding to the drilling depth, and tighten the screws again. In this case, the division on the dial corresponds to the full drilling depth, including the conical part of the drill sharpening.

Cam 18 is used to configure automatic reversal of the spindle direction when cutting threads. The installation of this cam is similar to the installation of the mechanical feed switching cam. In this case, the feed cut-off cam is moved back 10 mm. The spindle rotation direction is changed by reversing the electric motor.

The knurled cap, located in the center of the cross handwheel, is used to turn off the power feed if you need to drill or tap with manual feed. To turn on manual feeding, the cap must be pressed away from you until it stops.

The belts are tensioned by moving the bracket with the electric motor using tension screws located on the rear wall of the gearbox. To tighten the spring of the safety clutch, which turns off the feed when overloaded, use a special screw with an internal hexagonal hole, located under the cap of the upper cover of the bracket. Normally, the spring is adjusted to turn off the feed when an axial force exceeds the rated feed force by 10%, i.e. at 1800 kg.

Technical features

A special feature of the machine is that it has a dynamic spindle braking system.

The electrical equipment of the unit is presented in the form of an electric motor with a power of 4.4 kW. The device is equipped with an electric pump that supplies coolant. The pump is type X14-22M.

The specified vertical drilling machine has a number of technical features:

• the maximum possible diameter of parts that can be drilled on the machine is 50 mm,
• the spindle, due to the presence of a reversing device in the apparatus, is capable of performing rotations in different directions,
• The device is equipped with a 9-speed gearbox, thanks to which the spindle makes up to 1100 revolutions per minute,
• the unit is controlled exclusively manually; no automated systems are provided for it.

The 2a135 drilling machine allows the use of machine taps designed for thread cutting, which is ensured by the presence of a reversible device in the design.

PRODUCT SAMPLE ACCURACY

3 Product sample accuracy

3.1 General requirements for product samples - according to GOST 25443.

3.2 Accuracy of holes and center distances of the sample-product (for computer-controlled machines) For testing, use a pre-processed sample in the form of a square plate (Figure 24, Table 15).

Figure 24

Table 15

In millimeters

The base and edges of the sample product are finally processed.

Table 16

The sample is installed in the middle part of the table symmetrically to its center line and each hole is processed. The tolerance range for the diameter of the drilled hole should not exceed H12 - for machines of accuracy class H; H11 - for machines of accuracy class P. If necessary, to perform measurements after drilling on the machine, the holes are reamed. Holes are measured using universal instruments. Measurement of interaxial distances is carried out in the upper or close to it plane of the sample using:

a) mandrels inserted into machined holes, and plane-parallel gauge blocks (tiles);

b) coordinate measuring machine, instrumental or universal microscope;

c) a special device designed for measuring interaxle distances. The error of the center distances is equal to the difference between the specified and actual distances between the axes of any two holes.

Operating procedure on the machine

Setting up the machine for operation consists of installing the table and drilling head in the positions required for operation, clamping them on the column, and setting the required rotation speeds and spindle feeds.

The 2S132PF2I machine provides the following control modes:

1. adjustment (manual control from buttons);
2. automatic (control from DRO K524);
3. semi-automatic (positioning of the table according to the program from the DRO device, and the approach and removal of the quill with the spindle manually).

To establish the adjustment mode, it is necessary to set the “Mode selection” switch on the machine control panel to the “Adjustment” position.

Working on the machine in the “Adjustment” mode is carried out by pressing the corresponding buttons on the control panel.

To select the movement axis, use the “Select X and Y axes” switch. To move the table in positive and negative directions, use the “Positive direction of movement” buttons, respectively. To control the direction of spindle rotation, use the “Spindle rotation to the left” buttons on the control panel.

To rotate the gears in the gearbox when switching spindle rotation speeds, use the “Spindle Rotation” button.

The 2S132TS machine provides the following control modes:

1. manual mode;
2. auto.

In manual mode, set the “Mode selection” switch to the middle position “Manual mode”. The machine is controlled by pressing the corresponding buttons on the machine console “Spindle rotation to the left”, “Stop”. The working feed is carried out both from the steering wheel and using a mechanical transmission from the main movement electric motor.

In automatic mode, set the “Mode selection” switch to the extreme left position “Drilling”. Set the cams depending on the processing depth. Using the steering wheel, move the spindle to the upper starting position. Press the “Start cycle” button.

How to choose a drilling machine for your home workshop and garage

To choose a machine for home use or a garage workshop, you need to carefully study the models you like to see if they meet the basic criteria.

Supply voltage

If we consider machines in terms of power, then models powered by 380 V are more powerful than those running on 220 V. However, if you do not have the possibility of a three-phase connection, then a machine with 380 V will not suit you; it is better to opt for a model that works from a regular household outlet.

Rotation speed and adjustment method

The rotation speed of the drill chuck varies between 200-2800 rpm. This parameter directly affects productivity, but its effectiveness depends on matching the power of the machine, otherwise the equipment will slip very often. The rotation speed can be adjusted in two ways: stepwise, by rearranging the belts on the pulleys and by smoothly turning a special switch on the body. The second option is more convenient for the user, especially with little experience working on similar machines.

Power

The high power of the device ensures long-term continuous operation, which affects productivity. The power rating also indicates whether the machine can handle hard materials without the tool getting stuck.

If the machine is needed to work with plastic and wood, then its power should be 350-450 W. For steel or aluminum, choose a 500-600 W machine (if the workpiece thickness is from 2-5 mm). Thicker workpieces will require higher power - from 700 to 900 W. For professional work and processing of hard materials, it is preferable to buy machines with a power of 1000 to 1600 W.

Maximum diameter and drilling depth

Household machines can create holes with a diameter of 13-16 mm; for industrial machines this figure can reach 40-50 mm. This indicator must be taken into account if you are drilling materials for large bolts. You also need to look at the depth of the holes, it varies between 20-50 mm.

IMPORTANT! If your work involves thick materials with a cross-section of up to 5 cm, then you should buy the appropriate machines.

Chuck type

Drilling machines are equipped with three types of chucks:

1. Key. Using a special key, the toothed ring is rotated to more securely fix the drill. It takes more time, but the equipment is held more securely, so this method is used very often.
2. Klinova. The shank in this case has the shape of a cone and is mounted in a chuck with the same inlet hole. The advantage is that drills can be changed very simply by knocking out a wedge through the groove. The drill is held securely, but such a chuck is installed exclusively on large drilling machines.
3. Quick-clamping. The cartridge is fixed without the use of special tools. However, this does not affect the security of the shank, which makes machines with a keyless chuck most suitable for light tasks.

Working stroke

By working stroke we mean the stroke of the quill. The product remains motionless, only the chuck with the fixed drill is lowered. The quill stroke ranges from 5 to 14 cm. The larger this parameter, the easier it is to work with large workpieces and parts without lowering the stand, which increases productivity.

Ergonomics and safety

When purchasing a drilling machine, you should pay attention to how conveniently the power and control buttons are located, whether there are tips on the handles, how the drives for raising the table and increasing the distance between the vices are located.

To ensure the safety of the equipment, the manufacturer must supplement the model with a protective screen for the cartridge and high-quality insulation on the keys. It is also necessary to have an emergency stop button and a magnetic restart interrupter. Such equipment will protect the operator from injuries, and parts from defects and inaccuracies during processing.

Weight and dimensions

If we talk about the size and weight of stationary drilling machines, they are quite significant and indicate the need to immediately select a permanent location in a workshop or workshop. The weight of the model can be in the range of 20-150 kg, and the height of the stand can reach 70-110 cm. This allows you to place tanks, frames and other large-sized structures under the cartridge. Large machines are also suitable for drilling holes on finished products.

Small machines weigh from 12 to 25 kg, which allows you to move them or take them with you on the go. However, it is important to take into account that their height is small, so such models can only be used for working with workpieces, and not with volumetric parts.

Additional features

Additional functions can greatly facilitate working with the machine:

• illumination of the working area, which improves accuracy and allows you to work even in low light conditions;
• laser target designator;
• a coolant supply system that protects the material from deformation due to heating;
• LCD display that allows you to monitor the rotation speed and depth of drill placement;
• reverse rotation of the chuck, making it easier to remove the equipment when it gets stuck in the material.
