A ball cage positioning device

Abstract

The invention provides a locating device for constant-velocity universal joints, and belongs to the technical field of work-piece locating. The locating device solves the problem that the constant-velocity universal joints cannot be held or located by universal clamps in the prior art. The locating device for the constant-velocity universal joints comprises a lower guide plate and an upper guide plate; a plurality of constant-velocity universal joint direction controllers are arranged in the length directions of the guide plates, the distance between every two constant-velocity universal joint direction controllers is an integral multiple of the circumferential distance of windows on the constant-velocity universal joints, and each constant-velocity universal joint direction controller comprises two opening-closing plates capable of extending into the constant-velocity universal joint windows; rotary drums are arranged on the guide plates in a rotating mode, the guide plates are provided with rotation control mechanisms controlling the rotary drums to rotate relative to the guide plates, and the upper end faces of the rotary drums are flush with the surfaces of the guide plates; and the upper guide plate is provided with a mechanism controlling lifting and horizontal moving of the upper guide plate. According to the structural feature that the constant-velocity universal joints are provided with the constant-velocity universal joint windows, the constant-velocity universal joints can be held and located, multi-angle adjustment of the constant-velocity universal joints can be realized, and therefore the machining requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of workpiece positioning, and relates to a positioning device, in particular to a ball cage positioning device. Background technique [0002] With the rapid development of the automobile industry, constant velocity universal joints occupy an important position in the automotive drive shaft industry with its unique constant angular velocity torque transmission and superior mechanical properties, and the quality of constant velocity universal joints is even more important.

[0003] The ball cage, that is, the universal joint cage, needs to be positioned better during the production and processing process. However, due to the unique shape and structure of the ball cage, it is not conducive to the positioning of the universal fixture. The clamping mainly depends on the manual clamping of the operator, which requires high skills of the operator, especially when the position of the ball cage needs to be adjusted frequently in order to realize the processing of different parts of the ball cage, and manual operation cannot satisfy Require
