The invention relates to the machining of parts in the environment of free abrasive, metallic and non-metallic fillers and can be used in machine building and instrument making for cleaning, grinding, finishing and strengthening machining of parts.

The aim of the invention is to improve processing performance by communicating additional vertical uninterruptions to the working chamber.

FIG. 1 shows a structural diagram of the device; in fig. 2 - installation diagram of the intermediate drum; in fig. 3- device in axonometry; in fig. 4 - overrunning clutch, in a perspective view.

The device consists of a working chamber 1, for example, a cylindrical or other axisymmetric form with covers 2 and 3, which is mounted on spring-loaded supports 4 and in the lower part is covered by the upper horizontal branch of a flexible endless belt 5, made, for example, in the form of a flat belt and driven by the driving drum 6. The bending tape 5 also covers the intermediate drums 7 and the driven drum 8. The intermediate drums 7 are installed with the possibility of relative rotation on the same axis as the leading 9 and driven by 10 chain sprockets transfer.

Between intermediate drum 7 and drive sprocket 9, an overrunning clutch 11 is installed. At the ends of sprockets 9 and 10, crank pins 12 are eccentrically mounted, on which a connecting rod 13 is fitted with a tension roller 14. The drive sprocket 9 of the chain drive is kinematically connected with the V-belt drive 15 and the engine.

The separator 16 is fixed in a predetermined (upper) position by the pawl 17.

The device works as follows.

The parts to be processed and the filler processing bodies (abrasive, metal balls, rollers, sprockets, etc.) are loaded into the working chamber and closed with lids 2 and 3 (Fig. 1). The motor of rotational motion of the leading drum 6 is turned on, from which the bending belt 5 receives its movement. Due to the rubbing of the embracing (upper) branch of the flexible tape 5 with the cylindrical working chamber 1, the latter is rotated. When the flexible belt 5 is moving, the intermediate 7 and driven 8 drums also rotate.

Intermediate drum 7 (Fig. 2) through an overrunning clutch 11 is driven into rotation leading sprocket 9, connected with the chain driven sprocket 10. When rotating stars 9 and 10 with Krivostipnymi fingers 12, the connecting rod 13 makes a plane-parallel movement and the tension roller 14 during the half-period of its reciprocating motion, it presses on the cascading (lower) branch of the flexible tape 5, pulls the latter and causes the rotating working chamber to move upwards. During the second half-period of its reciprocating movement, the tension roller 14, moving progressively upwards, does not pull the flipping branch of the flexible tape 5. At the same time, the working chamber 1 under the action of its own weight and loading mass is lowered. Thus, in addition to the rotational, the oscillating movement of the working chamber 1 with a given amplitude A, determined by the tension of the branches of the flexible tape 5, and frequency f, determined by the frequency of rotation of the motor shaft. Under the action of circular rotation and low-frequency oscillations, the components of the mass of the load perform complex spatial motion at different speeds. In the process of relative movement of the filler particles relative to the surface of the workpiece, their mutual friction and impact interaction, the parts are processed (cleaning, grinding, finishing, strengthening treatment, etc.).

Upon completion of the processing cycle, the rotation of the working chamber 1 is stopped by disconnecting the drive of the leading drum 6, while the oscillatory movement of the working chamber 1 is continued from the engine through the V-belt drive 15, the overrunning clutch 11, the chain drive, etc.

0 Opening the covers 2 and 3, turning the pawl 17, free the separators 16 and lower them into the chamber (the position of the separators at the time of unloading and separating the processed parts from the filler particles in Fig. 1 is shown with a dash-dotted line), rigidly fixing with covers 2 and 3 for ensuring the transmission of vibrations from the chamber to the grids of the separator 16.

The mass of the load due to the circular low-frequency vibrations moves in the working

0 the chamber along a circular path and is discharged onto the sieve of the separator 16. At the same time, the particles of the medium, waking up through the sieve cells, are returned to the working chamber 1, and the sieve parts are diverted to the receiving container. The number of separating sieves is accepted.
