Abstract

The invention relates to mechanical engineering and can be used for machining flat surfaces. The aim of the invention is to improve the productivity and quality of machining due to the ratio of additional movement of the part and uniform wear of the lap. When switching on the vibrating machine of the lapping, plate 1, reciprocating, oscillating vertical movements and reciprocating rotary oscillatory movements around the vertical axis are set. Under the action of this centrifugal force of the cassette 2 with parts 3, moving to the periphery of the lapping plate 1, compress the elastic element 4. Since the magnitude of the centrifugal force changes the value from zero to maximum, the compression ratio of the elastic element also changes. Thus, the cassettes 2 with parts 3 make additional voter-forward radial oscillations. By affecting the details of the 3 additional oscillations, the productivity of the machining process and the efficiency are increased. In addition, the movement of parts ensures the use of most of the lapping plate 1, which leads to more uniform wear, and the presence of grooves 6 in the load plate 7 and protrusions on the cassettes does not allow parts in the finishing process to be concentrated in one part of the lapping plate, which . promotes its uniform wear. 3 ill., 1 tab.

The invention relates to mechanical engineering and can be used for machining flat surfaces of parts.

The purpose of the invention is to increase the productivity and quality of processing by telling the additional movement of the part and. uniform wear priter.

Fig, 1 shows the device section; in fig. 2 - cassette; in FIG. 3 - load plate.

The device consists of a lapping plate 1, which, given a reciprocating vertical movement and reciprocating rotational movement. Inside the lapping plate 1 there are placed the cassettes 2 with the parts 3. Elastic elements 4 are placed between the cassettes 2 and the collar of the lapping plate 20. In the upper end of the cassettes 2 there are protrusions 5 which go into the radial grooves 6 of the loading plate 7, allowing moving the cassettes 2 along the slots 6.

The device works as follows.

When the vibrating machine (not shown) is turned on with the lapping plate 1, the reciprocating oscillatory movement in the vertical plane and the reciprocating rotational movement around the vertical axis is set.

In the process of oscillatory motion, centrifugal forces arise whose magnitude depends on the frequency of the oscillations and. the mass of the workpiece - and. Under the action of this centrifugal cartridge cartridge 2 with parts 3, moving to the periphery of the grinding plate 1, compress the elastic element 4.

Since the magnitude of the centrifugal force enters the value from zero to maximum, the degree of compression of the elastic element also changes.

Thus, the cassettes 2 with the parts and 3 additionally make return-and-translational radial oscillations.

By affecting the details of the 3 additional oscillations, the process efficiency and efficiency are improved. In addition, the radial movement provides the use of most of the lapping plate 1, which leads to more uniform wear. The presence of the grooves 6 in the load plate 7 and the protrusions 5 on the cassettes does not allow the parts 3 to be concentrated in one part of the wiping plate, which also contributes to uniform wear.

Testing devices were carried out on the installation of vibroabrasive finishing VIK. 4 micro sections were processed simultaneously. Kharkiv-DM5 GOST 16877-71 abrasive paste was used. Surface roughness before processing Rg, after processing - RCI 0.063. The pressure was maintained at 0.2 MPa.

The test results are presented in the table.

The table shows that vibrodiving of flat surfaces with the imposition of additional radial oscillations improves the process efficiency, increases efficiency and reduces wear on the lap.
