or compressed air. The back cover 24 (FIG. 1) of the pneumatic cylinder 21 has a bearing support 25 placed in the supporting plate 17 and a gear 26 connected to the rod-rack 27 of the pneumatic cylinder 16, which serves to rotate the actuator 2, the compensating mechanism 3, the pneumatic system 5, the doors 6-9.

The base 14 of the robot is attached to the stand 28, which is fixed to the foundation. A column 29 is attached to the base 14, on which a jacket 12 with a cover 11 sits loosely. A pneumatic cylinder 16 with a bracket 30 and a distributor 31 is fixed to the column 29. A pipeline 32 for compressed air is placed inside the column 29, which is connected to the internal cavity of the guide 33, and electrical conductors 34 (FIG. 8) passing through pipe 35 through guide 36. Supporting pitch 17 is rigidly fastened to the column 29 (FIG. 1) and the base 14 on which the air distributor 15 is fixed. Rod 37 (FIG. 2) of the air distributor 15 is in contact with pores 20. Springs 38 and 39 (Fig. 1), n Located on the rod 18 between the cover 11 and the front cover 40 of the pneumatic cylinder 2, are used to lift the actuator 2, the compensating mechanism 3 and the pneumatic system 5 to prevent an emergency situation in the absence of compressed air in the system.

The nut 41 secures the pneumatic cylinder 21, the compressed air to which is supplied through the pipe 42 into the rod cavity, and through the rod 18 into the rodless cavity.

The actuator 2 (FIG. 1) serves to perform technological operations — stripping bays on the casting 43. It consists of a wiper 44 and a housing 45 (FIG. 2). The cleaning head 44 consists of a grinding wheel 46 enclosed in a casing 47 and mounted on a shaft 48 housed in a bearing housing 49. A pulley 50 is rigidly fixed on the other end of the shaft 48 and connected with a V-belt drive 51 with a pulley 52 mounted on the motor 53. The cleaning head .44 is connected to the cargo suspension 4, on which the goods 54 are seated, by means of a tension cable 55 and deflecting rollers 56. The cleaning head 44 and the engine 53 are rigidly fixed on the plate-plate 57. The plate-57 is attached in its upper part through the bearing op The bores 58 to the housing 45, consisting of racks 59 and ties 60, are fastened to the base plate 61, which is rigidly attached to the cover 11. Doors 6 to 9 are attached to the housing 45 (Fig. 1).

The compensating mechanism 3 serves to compensate for the necessary connection between the grinding steep 46 and the casting 43, i.e. it serves to compensate for the wear of the grinding wheel. The compensating mechanism consists of a ratchet wheel 62 (Fig. 1, 3, 5, 6), the inner diameter of which has a thread 63; L-screw 64, mounted in the ratchet wheel 62 and resting on the supports 65, which are attached to the support frame 66, and the latter to the plate 61 of the housing 45. Limiter 67 (FIGS. 2 and 6) prevents rotation of the G-shaped screw 64 and rigidly mounted on the tiller plate 57. The turn of the ratchet wheel 62 (FIGS. 5 and 6) is carried out by the dog 68 (FIG. 4) hinged on the axis 69 in the fork 70. The latter is screwed into the rod 71 of the pneumatic spring 72 (Fig. 5 and 6), rigidly fixed to the frame 66, consisting of the housing 73, the piston 74, the spring 75, the rod 71. On the fork 70 fixed adjustable ovochny screw 76 (FIG. 4) and through the axis

Q 69 is fixed to guide 77 (Fig. 6) located in support 78 of frame 66.

Pneumatic system 5 (Fig. 3) consists of air preparation device 79, pipelines 80 and air distributor 81. Doors 6-9 serve to better serve actuator 2, compensating mechanism 3 and pneumatic system 5. Doors are hingedly attached to body 45 with loops 82 Electrical equipment 83 is placed on base plate 61 and on doors 6-9. Plug connectors are fixed at the bottom of the column 29 on the flange 84 (Fig. 1). Electrical equipment 83 serves to ensure cyclic automatic start and stop of the actuator 2 and the compensating mechanism 3.

 The initial position of the mechanisms of the robot. The working environment - compressed air - is supplied to the robot, the electrical system is turned on. Actuator 2, compensating mechanism 3 are in the extreme

0 is in the upper position, i.e. the compressed air is supplied to the rodless cavity of the pneumatic cylinder 21 of the lifting mechanism 13. The piston 74 (FIG. 5) is in the extreme left position. Compressed air is supplied to the rod end of the pneumatic cylinder 16

5 (Fig. 1). Stripping head 44 is in the extreme forward position. The load 54 presses the wiper head 44 together with the plate 57 to the L-screw 64. The device operates as follows. . Having received the signal from the end switch of the moving casting on the conveyor, the motor 53 is turned on (Fig. 1). At the same time, the air distributor 81 (Fig. 3) switches and compressed air flows through conduit 42 (Fig. 1) into the rod cavity of the pneumatic cylinder 21 of the lifting mechanism 13, which brings the actuating and compensating mechanisms into working position, i.e., lowering them.

At the same time, the compressed air also enters the rodless cavity of the housing 73 and the rod 71 with the dog 68 by means of the ratchet wheel 62 and moves the L-shaped screw 64 by the amount of wear of the grinding wheel. The plate-trough 57 using a rope 55, attached at one end to the load 54, through the rollers 56 is constantly pulled to the paw of the L-screw. The processing of casting bays takes place. Disconnection of the actuator 2 and the compensating 3 mechanisms is carried out from the limit switch installed on the conveyor (not shown).

The installation of the limit switches at the beginning of the treatment, at the length of the surface to be treated and at the end of the treatment is provided at the place of use of the robot. After turning off the electric motor 53 and simultaneously switching the air distribution to raise the general labor culture in foundries.
