Designation of the main parts of the drilling machine 2Р135Ф2
- Machine base
- Table slide
- Turret
- Spindle head (caliper)
- Gearbox
- Feed reducer
- Control pendant
- Cabinet with electrical control equipment
- Cabinet with CNC equipment
- Column
- Cross table
On the base (bed) 1 of the machine there are slides 2 of the cross table, which has telescopic protection for the guides. A spindle head moves along the vertical guides of the column, on which a six-spindle turret head is mounted, allowing automatic tool change according to a control program. To speed up manual tool replacement, a special pressing device is provided in the turret. The machine can be controlled from a pendant control panel.
Movements in the machine
- The main movement is the rotation of the spindle with the tool
- Movement along the machine axes:
- X-axis - longitudinal feed - longitudinal movement of the table along the slide guides
- Y axis - transverse feed - transverse movement of the slide along the bed guides
- Z axis - vertical feed - vertical movement of the spindle head (support) along the rack guides
To control table movements (X and Y coordinates) from a program recorded on punched tape, machines are equipped with various CNC devices (one of the most common is the CNC “Coordinate S-70”). Feed along the Z coordinate is carried out in cyclic control mode. For coordinate movements of the table, manual data input on the CNC console can also be used. The presence of a digital display allows you to visually monitor the position of the table, as well as monitor the correctness of the program recording on punched tape.
The machines provide feedback on the position of the working bodies on each of the two movements controlled by the punched tape. Circular electrical contact code converters are used as feedback sensors. Movements of the turret head during fast and working strokes in both directions are limited by adjustable cams acting on switches (electric stops).
Kinematic diagram of the drilling machine 2Р135Ф2-1
Kinematic diagram of the drilling machine 2р135ф2-1 with CNC 2П32-3
The kinematic diagram of the machine (Fig. 4.6) consists of the following independent kinematic chains: main movement drive (rotation of the turret spindles); cross table feed drive; caliper drive with turret head; turning the turret head; pressing tools out of spindles.
Main movement chain
Main movement chain: two-speed asynchronous electric motor M1 (N = 4/4.5 kW; n = 1470/990 rpm) - 29/41 gear transmission - shaft I - shaft II (through gears 24/48 and 36/36 at engaged couplings M1 and M2 or through gear 14/36 with engaged coupling M3) - shaft III (via gears 14/36 and 48/24 with engaged couplings M4 and M5) - shaft V through bevel gear 21/21 - to one of turret spindles through 35/42 gears; 31/49; 49/47; 47/35.
Cross table feed drive chain
The feed drive chain of the cross table has two gearboxes, one of which moves the table along the slide (X-axis), and the second drives the movement of the slide along the frame (Y-axis).
Kinematic chain of the slide drive
The kinematic chain of the slide drive ensures their fast, medium and slow movements. Fast movement (at a speed of 7000 mm/min): M4 electric motor (N=0.6 kW; p=1380 rpm) - 16/40 gears; 34/22; 22/52; 52/34 - ball screw.
Moving at medium speed (200 mm/min): M4 electric motor - 16/64 gears; 25/55; 25/55; 38/42; 22/52; 52/34 - ball screw. Slow movement (at a speed of 50 mm/min): M4 electric motor - 16/64 gears; 25/55; 25/55; 16/64; 22/52; 52/34 - ball screw. A feedback sensor is mounted on the ball screw.
The table moves along the slide from the M5 electric motor (N = 0.6 kW; n = 1380 rpm); the kinematic chain of the drive of this movement is similar to the kinematic chain of the drive of the slide movement.
Turret Caliper Drive Chain
Caliper drive chain with turret head: DC electric motor M2 (N = l.3 kW; n = 50..2600 rpm) - 13/86 gear (or 37/37 gear - 4/25 worm gear - lead screw, equipped with a brake clutch (preventing arbitrary lowering of the caliper when the electric motor is turned off) and a remote control feedback sensor.
Turret rotation drive chain
Turret head rotation drive chain: M3 electric motor (N=0.7/0.9 kW; n= 1400..2700 rpm) - 23/57 gear - 1/28 worm gear - 16/58 gear - turret body .
Pressing tools out of spindles
Pressing tools out of spindles: M3 electric motor - 18/52 gear (with the clutch engaged) - 1/28 worm gear - 21/21 gear - eccentric mounted in the groove of the turret head rotation axis and pressing tool.
Lubricating the turret support
Lubrication of the turret head support is carried out forcibly according to the following scheme: MZ electric motor - 18/52 gears; 52/75 - EZ eccentric, driving the plunger pump.
Gearbox lubrication
The gearbox is lubricated by a gear pump driven by the gearbox electric motor through a V-belt. The oil supplied by the pump enters the distribution chamber, where it is distributed to lubricate all moving parts of the gearbox and electromagnetic clutches, and then drained into the reservoir. The oil level is controlled by an oil indicator.
Lubrication of caliper feed gearboxes and cross table
Lubrication of the caliper feed gearboxes and the cross table is carried out by spraying oil onto the gears. The oil level is monitored visually using oil indicators.
Lubricating the guides and screw pairs of the cross table
The guides and screw pairs of the cross table are lubricated manually using a lubricator. The bearings of the turret spindles are lubricated with grease.
Coolant supply
The coolant is supplied from a centrifugal pump. To cool the tool in the cutting zone, an individual drive is provided, which allows you to direct a stream of coolant to the desired location. The supply of coolant in the automatic cycle begins when the caliper moves down (the beginning of the working feed) and stops when the caliper begins to return to its original position (in this case, the corresponding toggle switch must be turned on on the control panel).
Electrical equipment of the machine
The electrical equipment of the machine consists of a separate cabinet of relay automation and CNC, as well as elements installed directly on the machine. Electrical connections between the machine components and the CNC are made by harnesses in metal hoses ending with connectors.
The electrical circuit of the machine provides the following operating modes:
- commissioning;
- semi-automatic with task input from CNC switches;
- semi-automatic with task input from punched tape;
- automatic with task input from punched tape.
The mode is selected using switches located on the control panels of the machine and the CNC.
Kinematics of a vertical drilling machine 2Р135Ф2-1. Rotate the turret head.
Section: LIBRARY OF TECHNICAL LITERATURE Short path https://bibt.ru<<Previous page Book table of contents Next page>>
Kinematics of the machine. The main movement of the 2Р135Ф2-1 machine, the turret spindle, receives from an asynchronous two-speed electric motor M1 (N = 4/4.5 kW, n = 1000/1500 min-1) through a gear z = 29-41, an automatic gearbox providing six rotation speeds by switching electromagnetic couplings M1-M5 and then through gears z = 21-21, z = 37-37, z = 37-42, z = 31-49-47-35 (wheel z = 35 is installed on each of the six spindles , but only the one located on the running spindle receives rotation).
Kinematic chain equation for minimum spindle speed
The gearbox is lubricated by a pump driven by the M1 electric motor through a V-belt drive. The hole in the spindle for installing the tool is made under Morse taper No. 4.
The vertical feed of the 2Р135Ф2-1 support with a turret head is carried out from a DC electric motor M2 (N = 2.2 kW, n = 3000 min-1). Lead screw XXXIII with a pitch Рх.в = 8 mm is connected by a cross coupling to the shaft of a non-contact synchronizer type BS-155A, which is a feedback sensor along the Z coordinate.
Working feeds of the caliper occur when the electromagnetic clutch M6 is turned on, through gears z=13-86, z=37-37-37, z=4-25. Rapid movement of the caliper is carried out when the M7 clutch is engaged through gears z=37-37, z=4-25. Rapid movement speed of the caliper
An electromagnetic clutch is installed on shaft XXXII, which brakes the working feed along the Z coordinate. On shaft XXXIV there is an impeller for spraying oil.
Rice. 68. Kinematic diagram of a vertical drilling machine 2Р135Ф2-1 with CNC
The rotation of the turret head of the vertical drilling machine 2Р135Ф2-1 is carried out from the M3 electric motor (N = 0.75 kW, n = 1500 min-1) through gears z = 52-17, z = 18-52 with the M8 coupling engaged, a worm pair z = 1-28, gear pair z = 16-58. The head is secured by spring-loaded caliper rods located in the grooves of the turret. When the M8 clutch is turned on, the worm z = 1 cannot turn the worm wheel z = 28, and therefore, while rotating, moves downward. By moving downwards through a rack and pinion pair with a rack wheel z = 27, shaft XX with eccentric E1 rotates. The turret head is released from E1 through a system of levers. At the same time, the second rack wheel z = 27 moves the rack on shaft XVI, thereby disengaging the wheel z = 47 on shaft X. The kinematic chain connecting the rotation drive to the spindle opens. The worm z=1 reaches a hard stop, and the turret begins to rotate to change the tool.
Simultaneously with the rotation of the turret head through gears z = 16-58, z = 30-30, a positional command device operates, which gives commands to select the position of the turret head, stop direct rotation and enable reverse rotation (the M9 clutch is turned on, M8 is turned off). The turret rotates in reverse until it reaches the hard stop of the caliper and stops. In this case, the worm z = 1, turning out of the worm wheel z = 28, moves upward; shaft XX rotates in the opposite direction, gear z = 47 is engaged with wheel z = 35. The head is fixed and the spindle receives working rotation.
Pressing out the tool of the 2R135F2-1 machine from the turret spindle is carried out from the M3 electric motor through wheels z = 18-52 with the M10 clutch engaged, a worm gear z = 1-28, a gear pair z = 21-21, and an E3 eccentric installed in the axis groove turning the turret head.
Lubrication of the 2Р135Ф2-1 turret caliper is carried out using an M3 electric motor through wheels z = 18-52-75, shaft XV, on which an eccentric E2 is installed, driving the plunger pump.
Positioning is accomplished by moving the table and slide. Gearboxes for longitudinal and transverse movements are identical in design and provide fast, medium and slow movement of the table and slide. An electric drive with step control is used here (see Fig. 26), the approach to a given point occurs first quickly, and then slowly at a “creeping” speed. Milling is performed at medium speed. Let's consider the sled movement reducer. Rapid movement of the slide occurs when the M11 clutch is turned on, then the movement from the M4 electric motor (N = 1.1 kW, n = 1500 min-1) is transmitted through gear pairs z = 40-40, z = 34-26-22-52-34 onto the rolling screw nut XXXIX with a pitch of P = 5 mm. The speed of rapid movement is determined from the expression
Slow movement of the slide occurs when the M12 clutch is engaged. Then the movement from shaft XXXIII is transmitted to the lead screw through gears z = 16-64, z = 25-55, z = 25-55, z = 16-64, z = 22-52-34. The average movement of the table is carried out from the M4 electric motor through gears z = 16-64, z = 25-55, z = 25-55, z = 38-42 (with the M13 clutch engaged), z = 22-52-34. Then
An electromagnetic brake is located on the lead screw XXXIX. Through an M14 cam clutch, the lead screw is connected to a feedback sensor - a synchronizer.
The thread-cutting chuck of the vertical drilling machine 2R135F2-1 allows you to cut threads from M6 to M24. When cutting threads, it is necessary that the machine feed per spindle revolution be slightly less than the pitch of the thread being cut. For example, when cutting M12x1.75 threads in cast iron workpieces, we select the cutting speed v = 4.7 m/min, then the spindle rotation speed n = 125 min-1, and the tap feed Smin = = nPn.r = 125 * 1.75 = 220 mm/min. The nearest smaller feed on the machine is Smin = 200 mm/min. The feed difference between the tap and the machine spindle is compensated by the chuck.

Setting up the machine
Regardless of the position of the operating mode switch on the CNC console, the adjustment mode is turned on by switch 23 located on the machine control panel (Fig. 4.7). In the adjustment mode, carried out by means of controls located on the machine console, the following is performed: turning the turret to a given position; pressing out the tool; turning spindle rotation on and off; moving the table along the X and Y axes in accordance with the selected speed and direction; moving the turret support along the Z axis in accordance with the task.
Machine control panel 2р135ф2-1
Setting the working parts of the machine to the zero position
The working parts of the machine are set to the zero position automatically before the “Program Entry” command. When button 15 is pressed, the turret support quickly rises until the limit switch is activated along the Z coordinate. The table moves until the limit switches are activated along the X and Y coordinates, and at the same time commands are sent to the CNC about the initial position of the working parts. The installation cycle is complete.
Rotating the turret
To select the position of the turret head, switch 24 is set to the desired position. By pressing button 6, the cycle of turning the turret head to the position specified by switch 24 begins. When you press button 6 and there is no task, the head moves non-stop.
Turning on the spindle in the “Setup” mode
The spindle is turned on in the “Adjustment” mode for all operations (except for thread cutting) with button 21, and turned off with button 22 (when threading, buttons 21 and 22 do not work). The spindle rotation speed is set by switch 27.
Movement of working bodies along the X, Y, Z axes
Movement of working bodies along the X, Y, Z axes. The selection of the working axis is made by switch 4.
The selection of fast, medium or slow movement is made by switch 7, and the selection of the direction of movement is made by switch 5.
Setting the program start in the XY plane
To adjust the start of the program in the XY plane, catchers or center finders are used. In manual mode, the spindle axis is aligned with the beginning of the program, and the zero offset values along the X and Y axes are entered on the CNC control panel, which give zero readings on the digital display.
The machine is adjusted along the Z axis after installing the cutting tool in the turret spindle. In the initial position of the caliper, check that the turret head does not touch the device with the workpiece clamped in it when rotating.

4. CNC milling machines
CNC milling machines are designed for processing flat and spatial surfaces of workpieces of complex shapes. The designs of CNC milling machines are similar to those of traditional milling machines, the difference from the latter lies in the automation of movements along the NC during shaping.
The classification of CNC milling machines is based on the following features:
• spindle location (horizontal vertical);
• number of coordinate movements of the table or milling head;
• number of tools used (single-tool and multi-tool);
• method of installing tools into the machine spindle (manually or automatically).
Based on their layout, CNC milling machines are divided into four groups:
• vertical milling machines with a cross table (652OF3, MA655F3, etc.);
• cantilever-milling (6R13F3, 6R13RF3, etc.);
• longitudinal milling (6M610F3-1, etc.);
• widely versatile instrumental.
In vertical milling machines with a cross table (Figure , a), the table moves in the longitudinal (X axis) and transverse (Y axis) horizontal directions, and the milling head moves in the vertical direction (Z axis).
Rice. 3. Layout of CNC milling machines with the designation of the coordinate axes X, Y, Z and W (a – vertical milling machine with a cross table; b – cantilever milling machine; c – longitudinal milling machine; d – longitudinal milling machine with fixed cross member; d – widely-universal milling machine)
In cantilever milling machines (Fig. 3, b), the table moves along three coordinate axes (X, Y and Z), and the headstock is stationary. In longitudinal milling machines with a movable crossbar (Fig. CNC.4, c), the table moves along the X axis, the spindle head moves along the Y axis, and the crossbar moves along the Z axis. In longitudinal milling machines with a fixed crossbar (Fig. 3, d) the table moves along the X axis, and the spindle head moves along the Y and Z axes.
In widely universal tool milling machines (Fig. 3, e), the table moves along the X and Y axes, and the spindle head moves along the Z axis.
