Description of design and operation of the designed accessory

Milling device for universal machine is assembled from USP-12 de-tales. This accessory consists of the following parts.

Two prisms (2) and (3) are installed on the plate (1). The part is based in prisms on surfaces 20k6 and 40k6. Due to the difference in the base diameters under the prism of pos.2, a lining of pos.5is provided. Prism pos.2 is based on two guide keys pos.14 screwed to the prism base with screws, pos. 19. The lining is based on plate slab pos.1 on two t-shaped keys pos. 24. Fastening bolts (pos. 11. Prism pos. 3 is based on four keys, pos. 14 screws screwed to the base of the prism, pos. 19. Prism is screwed to plate (2) with screws (pos. 11.

In the accessory the part is fixed by grips. Structurally, the grip consists of the following elements: In the grab of pos. 4. Adjustment bolt pos. 13 to the base, which by means of pin pos. 15 the heel is attached, pos. 23. A slot is provided in the tack, through which the stud pos. 7. The stud is screwed into the hole of the plate. Washers pos. 17, pos. 18, as well as springs, pos. 8, pos. 9 for corresponding prisms.

Attachment of the part in the accessory is performed using nut pos. 16. For an exception of a samorakruchivaniye of a nut and weakening of fixing of a detail washers of poses are provided in adaptation in a design of adaptation. 12 and pos. 10.

For ensuring basing of a detail in adaptation the level of poses is fastened to a prism 3. 23 with two screws, pos. 25.

To remove the part from the accessory, loosen the nuts of pos.16 and remove the grips in opposite directions from the part. Then install the part on prisms. Then the grips are supplied and the part is attached in the accessory. To avoid misalignment, adjust the adjustment bolt (pos. 13.
