Special fixture capable of preventing clamping deformation for special-shaped support seat

Abstract

The invention relates to a special fixture capable of preventing clamping deformation for a special-shaped support seat. The special fixture capable of preventing clamping deformation for the special-shaped support seat comprises positioning pillars, pressing plates, compression bolts, a positioning plate and support pillars, wherein the four positioning pillars are arranged and supported at the lower ends of four ear plates of a main body; outlines of the upper ends of the positioning pillars are identical to outlines of ear plate areas on the lower surface of the main body in a laminating way; the pressing plates are arranged on the ear plate areas on the upper surface of the main body; holes for the compression bolts to penetrate through are formed in the pressing plates; the compression bolts sequentially penetrate through the pressing plates, the ear plates and the positioning pillars so as to fixedly connecting the pressing plates, the ear plates and the positioning pillars intoa whole; the upper end surface of the positioning plate is fixedly connected to the lower ends of the positioning pillars; positioning holes corresponding to the positions of inner holes in the main body are formed in the positioning plate; and the support pillars are fixedly connected onto the lower end surface of the positioning plate. According to the fixture provided by the invention, the surfaces, located on the ear plate areas, of the end surfaces and the lower surface of a lug boss of the lower surface of a special-shaped support seat are positioned, so that the positioning area is large, the compression force is uniformly distributed, the product deformation after processing is effectively prevented, the product accuracy is improved, and the quality requirement of a product is ensured.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a special fixture for a special-shaped support seat that can prevent clamping deformation. Background technique [0002] The special-shaped support seat is an important part of the new energy power spindle box, which is used to locate the position distance and direction of the spindle. The structure of the special-shaped support seat is as follows: image 3 As shown, it includes a disc-shaped body 6, the edge of the body 6 is provided with four outwardly protruding lugs 61, the lugs 61 are provided with through holes 611 through the upper and lower surfaces of the lugs 61, and the lower surface of the body 6 There is a cylindrical boss 62 on the top, and the boss 62 is provided with an inner hole 621 passing through the upper and lower surfaces of the body. The outer wall of the boss 62 and the lower surface of the body 6 are arc-shaped transitions. The central axis deviates from the central...
