Description

ten

This invention relates to surface finishing with a free abrasive and can be used in various industries for vibroabrasive processing of small mass parts.

The purpose of the invention is to increase the processing capacity by eliminating stagnant zones and increasing the relative speed of the machined parts and p & b bodies.

FIG. 1 shows the proposed device, a general view; in fig. 2-g. Fastener fastening unit with pins.

The device contains an annular contour 5 tei er (tank) 1, a support disk 2 installed in its central part, on which radially strips 3 are mounted with 4 pins 5 fixed to them using nuts 5. A vibrator 6 is located in the lower part of the container. The slats 3 are rigidly connected to the turning plates 7 mounted on the brackets 8 fixed on the disk 2 with the help of the nut 9.

The container cavity is designed to be filled with the working mixture, parts 10 and working bodies 11. The supporting disk 2 is installed in the central part of the container 1 with the possibility of turning in the shaped grooves 12. A fixed change in the angles of the position of the disk 2 is provided with a nut 13. The figure groove 14 serves to change the angular position of the plate 7 fixed by nuts 15 and 16.

The device works as follows.

The working mixture (parts 10 together with working bodies 11) is loaded into container 1, which is then driven by vibrator 6 into an oscillatory motion. Thus, under the action of both the main (from the walls of the tank 1) and additional (from the pins 5) vibrations, the working mixture moves along a continuous spiral path around the central part of the container 1. As a result of this movement, the parts 10 are processed. 11, depending on their size, moves throughout the entire volume of container 1, and parts 10 can only be moved in the zone bounded by the bottom of tank 1 and the ends of pin 5 (which is provided mainly by transverse dimensions of the pin she is 5 and there are distances between them). Due to this, and also considering the fact that the working mixture receives additional oscillations from the pins 5, the speed of movement of the working bodies 11 relative to the parts 10 increases, which leads to an intensification of the process. Moreover, by changing the inclination of the pins 5 (in this case, it should be directed against the movement of the working mixture), it is possible to treat surfaces, internal openings of hollow parts. This becomes possible as a result of the fact that the hollow parts under the action of vibration, meeting the pins, are mounted on them and rise up, and the processing of the said parts is removed.
