In the upper part of the housing 9 there is a housing 12 with an inclined bottom 13 in which the guide sleeves 14 pass with toothed racks kinematically connected with the cross member 21 and the support table on which the workpiece is mounted and

which is placed with the possibility of vertical movement between the plates I and 2. On the top plate 1, the cleaning element-cleaning brush 23 is located for rotation, to remove chips, while the brush 23 is kinematically connected with the traverse drive 21. An adjustable stop 34 is installed in the housing 9, the apex of which is intended to interact with the working element-stem of the centering element, and the conical surface 39 with the stop. 4 il.

The invention relates to the processing of materials by cutting, in particular, to devices for installing parts on metal-cutting machines, for example vertical drilling machines, built into robotic complexes.

The purpose of the invention is to reduce the time for installation of parts.

Figure 1 shows the device, a general view; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; figure 4 - section bb In figure 1.

The device contains two plates, the upper I and the lower 2, connected by four posts 3. A replaceable conductor plate 4 is installed in the central hole of the upper plate 1, and a supporting flange 5 is placed at the bottom of the central plate 6 with a central annular groove 6 connected by radial channels 7 departing from it with through longitudinal cavities 8 for supplying coolant (coolant) to the tool working area (not shown). A box-shaped housing 9 is mounted on the bottom plate 2, in the lower part of which a hydraulic cylinder 10 is fixed in the supports 11. In the upper part of the housing 9 there is a casing 12 with an inclined bottom 13 in which holes are made for the passage of the guide sleeves 14. In the front wall of the casing 12 has a window 15 for handling the device by a robot hand (not shown).

A cogged rail 16 is mounted in each guide sleeve 14, which through gear 17 is engaged with the toothed sector 18,

which, by means of a lever 20 mounted on the shaft 19, is connected with the rod of the hydraulic cylinder 10.

The gear racks 16 carry the yoke 21 installed in their upper part, on which the support table 22 is mounted with the possibility of vertical movement between the upper 1 and lower 2 plates.

On the top plate D there is a cleaning element - a cleaning brush 23 for removing chips, mounted rotatably on the shaft 24, which is kinematically connected with the drive of the crosspiece 21 by means of a bevel gear 25.

The support table 22 with cross-shaped supports 26 contains a g centering mechanism, made in the form of a replaceable mandrel 27, in the opening -. which is located rod 28. The latter is connected by means of a threaded connection with a screw 29 having a tapered head which comes into contact with three wedge clamping elements 30 equally spaced around the circumference and spring-loaded with two rings 31, a spring 32 is placed on the lower part of the rod 28 a pin 33, which connects the centering mandrel 27 with the working element - a rod 28, the free horse of which has the ability to interact with a fixed stop 34 relative to the sleeves 14, also designed for interacting ones with the stopper 35 fixed to the cross member 21.

In the upper part of the housing 9 a collector 36 is installed for supplying coolant,

To remove the coolant outside the device, the radial channels 7 also connect the through pro-jugular cavities 8 with the cylindrical outer surface 37. The adjustable stop 34 communicates with the tip 38 with the rod 28, and the conical surface 39 with the stop 35. On the supporting table 22 there is a part 40 .

The device works as follows.

Before starting the traverse 21 with the supporting table 22 is in the lower position, resting on the restraint. by the tele 35 on the adjustable stop 34. The screw 29 is in the upper position, the clamping elements 30 are retracted under the action of the spring 32.

Through the window in the casing 12, the detail 40 by the robot hand is fed to the support table 22 and is put on the mandrel 27. The hydraulic cylinder rod 10 makes a working stroke and through the lever 20, the gear sectors 18, gears 17 and the gear racks 16 raises the yoke 21 and lifts the detail 40 to the support the flange 5. Simultaneously with the rotation of the shaft 19 through the bevel gear 25, the shaft is rotated with the brush 23 fixed thereto. The rod 23 is rotated to a position that does not interfere with the processing.

At the time of the descent of the limiter 35 with the adjustable stop 34, the rod 28 with the screw 29 under the action of the spring 32 takes the lower position, expanding the clamping elements 30 and the center part 40 on the mandrel 27. When the required pressure is reached in the hydraulic system, the machine (not shown) turns on and drilling four holes. At the same time, coolant is turned on to the support flange 5, which is fed through channels 7 to the cutting zone, with a local bath forming between the walls of the supporting flange 5 and the upper surface of the workpiece 4Q near each tool in cavity 8.

After finishing the treatment, the cylinder rod 10 lowers the yoke 21 on the adjustable stop 34. The rod 23 rotates and sweeps the stand from the conductor plate 4, the mandrel 27 releases the part AO and the robot arm removes the latter from the support table 22.

After that, the coolant supply to the collector 36 is turned on and the chips are flushed from the cross-shaped supports 26 of the support table 22.

Inclined chips

the bottom 13 flushes the coolant into the chip cleaning mechanism. After which the cycle of operation is repeated.
