Detailed Description
Example 1:
as shown in fig. 1-6, the pump cover dismounting device for the automobile oil pump comprises a main body and three clamping jaws 6 which are radially distributed around the center of the main body.
The main body is disc-shaped and comprises an upper plate 1, a lower plate 2, a bolt 3, an elastic retainer ring 4 and a cushion cover 5. The upper plate 1 and the lower plate 2 are both in the shape of a disc with the same size. The lower surface of the upper plate 1 is provided with three slots 11 which are distributed around the center in a shooting manner and used for inserting the connecting ends of the clamping jaws 6, the center of the upper plate 1 is provided with a stepped hole 12 used for installing the bolt 3, the center of the upper end of the upper plate 1 is provided with an operating part 13 used for butting a wrench, and the operating part 13 is an inner hexagon nut welded at the center of the upper end of the upper plate 1 or a regular hexagonal prism-shaped boss integrally formed at the center of the upper end of the upper plate 1. The center of the lower plate 2 is provided with a screw hole 21 into which the bolt 3 is fitted. The upper plate 1 is arranged right above the lower plate 2, and the bolt 3 sequentially penetrates through the elastic retainer ring 4, the cushion cover 5, the stepped hole 12 of the upper plate 1 and the threaded hole 21 of the lower plate 2 to press the upper plate 1 on the lower plate 2, so that the connecting end 61 of the clamping jaw 6 is pressed between the upper plate 1 and the lower plate 2.
