Description

eleven

The invention relates to the finishing-grinding treatment of parts in a container that perform low-frequency vibrations, and can be used in various areas of industry for grinding and polishing the surface of predominantly long parts.

The aim of the invention is to improve the operational properties of the device by eliminating the need for sealing windows in the end walls.

1 shows a schematic representation of the device, a general view; in fig. 2 is a section A-A in FIG. in fig. 3 is a view B in FIG. one ,

A device for vibratory processing of long parts contains a base 1, on which a container 3 is installed by means of npyKHJi 2 with an unbalance vibrator 4 fixed on it. At the bottom of the container 3, ribs 5 are installed at an angle to its longitudinal axis and symmetrically in plan. 3 centrally symmetrically in plan and with a gap relative to the bottom, partitions 6 are fixed, forming in the central part of the container the working compartment 7. In partitions 6 and the end walls of the container 3, windows 85 are coaxially mounted detecting workability

detail 9. Container 3 is filled with working medium 10,

The device works as follows

5 When the shaft of the unbalance vibrator 4 rotates in a clockwise direction (FIG. 3), the container 3 performs low-frequency oscillations in conjunction with the working medium 10, which rushes into the working compartment 7 and overlaps the surface of the workpiece 9. When the working medium 10 collides with the surface of the part 9 there is its finishing processing. Untreated parts of the surface of the part 9 are processed by sequentially moving it relative to the windows 8. The surface treatment of the part 9 occurs in the working medium 10 compressed by transport streams,

When the device of the window of the end walls is completely free from the working environment (in this case, abrasive granules), at the same time the bulk of the working medium is accumulated in the working compartment in accordance with FIG. 1, This arrangement of the working environment eliminates the need to use end wall seals, which In each instance, the treatments must have a specific shape and, in addition, they are subject to intense wear.
