Example Embodiment

[0027] Such as Figure 1~3 As shown, a positioning fixture for comprehensive metal processing of differential half-shaft gear blanks. The positioning fixture includes a fixture seat 10 on which a positioning ring gear for supporting the half-shaft gear blank 6 is fixed. 7. The clamp base 10 is also provided with a clamping device that cooperates with the positioning ring gear 7 to fix the semi-shaft gear blank 6.

[0028] There are many implementation schemes for the positioning ring gear 7, as long as it can support the semi-shaft gear blank 6 well, as the preferred scheme of the present invention, such as figure 1 As shown, the upper end of the positioning ring gear 7 is provided with a positioning tooth groove that meshes with the tooth profile of the semi-shaft gear blank 6, and the lower end of the positioning ring gear 7 is provided with a positioning mandrel; the upper end of the clamp seat 10 is provided There is a positioning hole matched with the positioning mandrel of ...

Abstract

The invention belongs to the technical field of gear metal machining, and particularly relates to a positioning fixture for comprehensive metal processing for a differential gear blank of a differential mechanism. The positioning fixture comprises a fixture seat, a positioning gear ring for carrying the differential gear blank is fixedly arranged on the fixture seat, and a clamping device which matches with the positioning gear ring for fixing the differential gear blank is further disposed on the fixture seat. By the aid of the positioning fixture, six machining procedures can be completed by one-step clamping, labor is saved, the problem of form and position errors caused by repeated clamping when a product is machined is solved, the precision of the product is improved, and the quality of the product is obviously enhanced. In addition, when the positioning fixture is used, unification of production rhythms of the working procedures or transferring is omitted, and the problem that operation needs to be stopped to wait for labor and materials is avoided. Besides, labor efficacy is improved, production energy consumption is lowered, and the machining precision of the differential gear, the quality of the differential gear and production efficiency reach advanced level of differential gear production.

Description

technical field [0001] The invention belongs to the technical field of gear metal processing, and in particular relates to a positioning fixture used for comprehensive metal processing of differential axle shaft gear blanks. Background technique [0002] There are seven main processes in the existing metal processing of the axle gear of the automobile differential gear before heat treatment, namely: the first process is drilling, the second process is punching and flashing, the third process is cutting the wheel spoke edge, and the third process is drilling. The four processes are rough turning outer circle and end face, the fifth process is finishing outer circle and end face, the sixth process is boring, inverted shaft end angle, inner hole angle, digging and retreating tool groove, and the seventh process is The inner hole angle of the inverted tooth surface. [0003] The traditional processing method uses one drilling machine, one punching machine and five multi-tool hy...
