Abstract

The invention relates to the technical field of positioning of three-pin shaft forks, in particular to a positioning mechanism used for machining of a three-pin shaft fork of an automobile transmission system. The positioning mechanism comprises a base, a power mechanism, a fixed platform, a movable platform and a proximity switch, wherein the power mechanism is arranged on the base; the fixed platform is fixed to the output end of the power mechanism and used for driving the fixed platform to rotate; the movable platform is connected in the direction of the axis of the fixed platform in a sliding mode relative to the fixed platform, the movable platform is radially fixed relative to the fixed platform, a spring is arranged between the movable platform and the fixed platform, and one or more positioning blocks matched with shaft holes in the three-pin shaft fork are arranged on the movable platform; and the proximity switch is used for detecting whether the movable platform moves or not and is in signal connection with a controller, and the controller is in signal connection with the power mechanism. According to the positioning mechanism provided by the invention, adaptive adjustment of the positioning blocks on the movable platform relative to the three-pin shaft fork can be achieved, and the three-pin shaft fork is automatically positioned during automatic production and machining.

Description

technical field [0001] The invention relates to the technical field of tripod yoke positioning, in particular to a positioning mechanism used for machining tripod yokes of automobile transmission systems. Background technique [0002] The three-pin shaft fork in the automobile transmission system generally relies on traditional manual positioning in production and processing, and the production efficiency is low. Since the bottom of the three-pin shaft fork has three axial holes distributed along the circumferential direction, the bottom of the three-pin shaft fork The cavity is not a round hole, which requires that not only the axis of the three-pin shaft fork must be aligned with the positioning device, but also its circumferential direction must be aligned with the positioning device, that is, the positioning block on the positioning device and the three-pin shaft fork must be aligned When the shaft holes are aligned, the positioning of the three-pin fork on the positioni...
