(

The invention relates to devices for blasting the surfaces of parts.

A device for blasting surface debris is known, comprising a nozzle hinged on a carriage mounted for return and forward movement along the guide of the OTHO frame relative to the surface of the workpiece l,

The disadvantage of the known device is that it does not allow high-quality surface treatment of the parts.

The purpose of the invention is to increase the processing efficiency.

This goal is achieved in the direction perpendicular to the movement of the trolley.

FIG. 1 is schematically depicted. The proposed device, a general view, in FIG. 2 - a mobile view of a bogie front view; in fig. 3 -, the same, top view; in fig. 4 - the same side view / in FIG. 5 is a kinematic diagram of a drive for longitudinal movement of the trolley | And a disjoint lateral movement of the bridge. Device For shot blasting, the surface consists of a fencing 1 with a consumable 2 and a receiving 3 bunkers, a bridge 4 with rollers 5 mounted on longitudinal tracks B, a trolley 7 with upper B and 9 lower rollers, which also moves on transverse rails : put x 10 mounted on bridge 4. The feed hopper 2 is rigidly fixed in the center of the fence and the outlet for the shot is connected to the inner tube of the telescopic pipe 12 entering the outer tube by means of a flexible hose 11. The outer tube is 13 tons Also, by means of a flexible hose 14, it is connected to the upper end of the pipe 15 of the nozzle 16, which is fixed by means of a hinge 17 in the center of the trolley 7.

For adjusting the inclination of the nozzle 16 relative to the surface of the workpiece 18, it is provided with a sector 19 with a slot and a lamb 20 of fixation.

The upper end of the pipe 15 is provided with re, zba, and when the adjusting nut 21 interacts with the body of the trolley through the sleeve 22, it is possible to raise and lower the lorsun in relation to the surface of the workpiece 18. The drive for the reciprocating movement of the carriage 7 (Fig. 5) along Jostnews is from the eRtp, the body 23 through the gearbox 24 with the endless traction cable 25, piled on the reel 26. The pjivto move the bridge 4 from the stepper motor 27 by winding the endless pulling line 25 on the drum 28. The device operates as follows omi-. Fraction, for example, the metal fraction 0.3) from the feed bin 2, via a telescopic conduit 12-15, goes to the injector 16. Simultaneously, the compressed air flows to the injector through pipeline 29; The electric motor 23 drives the longitudinal movement of the carriage (Fig. 5h) which rotates the drum 26 through the gearbox 24. The cable 25 winding the drum causes the carriage 7 to move. The carriage with the nozzle, moving part of the surface, in the final position of the trolley, the motor 23, the longitudinal movement is turned off, the stepper motor 27 of the cross-sweep of the bridge is turned on, and the bridge is displaced by one step The axle drive motor 27 is turned off and the trolley longitudinal movement motor 23 is switched on again, which is preliminarily reversed, after which the trolley movement cycle repeats. mounted on a trolley mounted with the possibility of reciprocating movement along the directions of the frame relative to the surface of the workpiece, characterized in that, in order to increase the processing efficiency, the frame is adapted to move in the direction perpendicular to the movement of the trolley.
