Problems solved by technology

[0002] At present, the fixture positioning is an integrated positioning plate structure, such as image 3 As shown, the part and the fixture positioning plate 15 are positioned through the gap. Due to the gap in the radial direction of the part positioning and the influence of broaching vibration, the surface quality of the tongue and groove of the broaching part cannot meet the technical requirements

Abstract

The invention relates to a fixture special for a mortise of a broaching disc type part, belonging to the technical field of fixture machinery. The fixture comprises a base, an angular positioning pin, a press cover, a compression nut, a compression screw, a gasket, a screw-thread bush, a lock screw, a positioning mandrel and radial gap elimination mechanisms, wherein each radial gap elimination mechanism comprises a positioning end surface ring, a positioning stop opening ring, a radial positioning gap regulation top block, a tightening screw and a spring. By uniformly distributing the radialgap elimination mechanisms on the circumferences of two layers of positioning rings, the fixture can eliminate the positioning radial gap of the part also enable the part to be coaxial with a positioning stop opening of a puller and enhance the production efficiency and the product qualification rate of the part and the qualification rate from original 10 percent to 95 percent and directly enhance the economic efficiency by 50 percent.

Description

technical field [0001] The invention belongs to the technical field of fixture machinery, and in particular relates to a special fixture for broaching disc parts. Background technique [0002] At present, the fixture positioning is an integrated positioning plate structure, such as image 3 As shown, the part and the fixture positioning disc 15 are positioned through the gap. Due to the gap in the radial direction of the part positioning and the influence of broaching vibration, the surface quality of the tongue and groove of the broaching part cannot meet the technical requirements. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a special jig for the tongue and groove of broaching disc parts, which can improve the surface of the broaching parts by evenly distributing the radial gap elimination mechanism on the circumference of the two-layer positioning ring. The purpose of processing quality. [0004] The te...
