Positioning device for machining outer circle gear teeth of automobile differential gear

Abstract

The invention discloses a positioning device for machining outer circle gear teeth of an automobile differential gear. The positioning device comprises a fixing disc, an annular fixing sleeve is arranged in the middle of the right side of the fixing disc, and a transverse screw rod is rotatably arranged in the middles of the fixing disc and the annular fixing sleeve through first bearing seats; atransverse threaded sleeve cooperating with the transverse screw rod is arranged in the annular fixing sleeve, a plurality of first inclined wedges are evenly arranged on the transverse threaded sleeve, and transverse guide rods are arranged at the left ends of the first inclined wedges correspondingly; a plurality of transverse guide holes cooperating with the transverse guide rods are evenly formed in the portions, at the left ends of the first inclined wedges, of the fixing disc, and a plurality of sliding rod sliding holes corresponding to the first inclined wedges one to one are evenly formed in the annular fixing sleeve in the radial direction; and limiting block sliding holes communicating with the sliding rod sliding holes are formed in the portions, on the inner sides of the sliding rod sliding holes, of the annular fixing sleeve.

Description

technical field [0001] The invention relates to a processing equipment for auto parts, in particular to a positioning device for processing outer circular gear teeth of an automobile differential gear. Background technique [0002] The automobile differential is one of the more important accessories in the automobile transmission equipment, and the gear is an important part of the automobile differential. In the production process of automobile differential gears, it is necessary to carry out various processing on the outer circular gear teeth. The gear positioning device currently used mainly has the following problems: 1. It can only position the gear shaft hole with a single diameter, and the positioning diameter is single. , the scope of application is small; 2. The shaft hole of the gear is easy to be clamped by the clamping part, resulting in the scrapping of the gear, the positioning effect is not ideal, and the scrapping rate is high; 3. After the gear is positioned,...
