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

Auxiliary movements - accelerated movement of the caliper, periodic rotation of the turret, precise and accelerated movements of the table and slide (positioning movement).

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.

Vertical drilling machine mod. 2р135ф2

This Computer Numerical Control (CNC) machine is designed for drilling, countersinking, reaming, threading, face trimming, etc. in low to mid-volume production. The presence on the machine of a six-position turret for automatic change of cutting tools and a cross table with program control will create the ability to carry out coordinate processing of parts such as covers, flanges, panels and other parts without preliminary marking and without the use of jigs, machine accuracy class N.

Numerical control system. Machine mod. 2Р135Ф2 is equipped with a numerical control device “Coordinate S70-3”, which ensures simultaneous movement of the table along the X and Y axes when positioning the movement control along the axis (from the coordinate), makes it possible to control the rotation of the turret, select the value of the working feed and spindle speed. The device has a digital display and allows for input of corrections for tool length.

A column is mounted on the base of the machine, along the rectangular vertical guides of which a support carrying a turret head moves. The gearbox and feed reducer are rigidly mounted on the column. The cross table has a base along which the slides carrying the table itself move in the transverse direction. The latter, in turn, can move in the longitudinal direction along the slide guides. The movement of the slide and table is carried out from the gearboxes.

Rotate the turret head. The head rotates using the following kinematic chain. From the MZ electric motor (0.7/09 kW, 1400/2700 rpm) through the shaft transmission to the shaft, from which the worm gear transmits the movement to the shaft and transmission, which rotates the turret head. The clutch must be engaged. Before turning the turret, it must be unlocked, since it is secured by spring-loaded caliper rods located in the grooves of the turret. When the shaft on which the worm sits rotates, it has the ability to move axially, so it turns out of the worm wheel and, moving down through the rack and pinion gear with the wheel and the module, turns the shaft with an eccentric, which will release the turret with a system of levers; at the same time, the second rack wheel moves the rack on the shaft and thereby disengages the wheel on the shaft. Thus, the turret head is released and the kinematic chain connecting the rotation drive to the turret spindle is broken. After this, the worm reaches a hard stop and begins to rotate the turret by means of a transmission, changing the tool (direct rotation).

Simultaneously with the rotation of the turret head through the transmission, the shaft and gear rotates a positional command device on the shaft, which stops the direct rotation of the turret head by reversing the electric motor, having previously reduced its rotation frequency to 1400 rpm. During reverse rotation, the turret reaches the hard stop of the caliper and stops; at the same time, the worm, turning out of the worm wheel, moves upward. The shaft rotates in the opposite direction, the gear engages with the turret spindle wheel. The head is fixed and the spindle begins to rotate. The choice of the operating sequence of the turret spindles is set on the console. There are six processing cycles in total.

The table moves from the M4 engine (0.6 kW, 1380 rpm). The table gearbox does not differ from the sled gearbox, therefore, its kinematic diagram does not indicate shafts and wheels.

Thread cutting. For cutting threads with a machine tap, chucks are used that can be installed in any position of the turret. When cutting threads, use a copier, a screw-nut in steps of 1.0; 1.25; 1.5; 1.75; 2.0; 3.0 mm, set of replaceable collets for fastening taps, adapter squares. The threading head has a mechanism for adjusting the operation of the head in the cycle forward (threading) - reverse (unscrewing the tap after cutting the thread). The full cycle of work with the support is provided by the electrical circuit of the machine. Rotation from the spindle is transmitted through a liner inserted into the spindle of the turret head, through a gear coupling to the driver, spline shaft and collet.

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.
