Lathe fixture

Abstract

A lathe fixture is particularly suitable for manufacturing and using sleeve parts. Eight points support an inner hole of a sleeve part blank; an angle between the front four points and the rear four points is 90 DEG; the fixture has high manufacturing precision, accuracy for positioning, and long service life; the wall thickness difference of the sleeve part is small; and the fixture can be effectively controlled in a specified range. The lathe fixture has the advantages that through the fixture, the wall thickness difference of the inner circle and the excircle of the sleeve part can be ensured.

Description

technical field [0001] The invention relates to a lathe fixture, which is especially suitable for mass production of sets. Background technique [0002] At present, most domestic machinery manufacturers use inner hole positioning for rough machining production of sleeve parts, and the fixtures are double-fold expansion sleeves or single-valve expansion sleeves. The effect is unsatisfactory. Due to the rough inner hole of the blank, the expansion sleeve form cannot guarantee the wall thickness difference between the inner and outer circles of sleeve parts, and cannot meet the ideal requirements of the inner hole surface. Contents of the invention [0003] In order to overcome the deficiencies of existing expansion sleeves, the present invention provides an 8-point support fixture. [0004] The technical method adopted by the present invention to solve the technical problem is to adopt 8 points to support the inner hole of the part blank, the front 4 points and the rear 4 p...
