Abstract

The invention specifically discloses a gear part shaving fixture which solves the problems that due to the fact that an existing tool for a gear part is large in positioning gap during unthreaded hole centering, a gear is poor in tooth shape and tooth direction. The gear part shaving fixture comprises a left mandrel assembly and a right mandrel assembly. The left mandrel assembly comprises a left base. A mandrel body is fixed to the center of the left base. The right end of the left base is connected with a hollow left positioning base. A pressing cushion is arranged in the left positioning base. A pressing ring is arranged on the right side of the edge of the pressing cushion. A left snap spring is arranged on the mandrel body. A tension spring is arranged in the left base. The right mandrel assembly comprises a stepped right positioning base. A conical sleeve is arranged on the left end face of the right positioning base. The inclined face of the conical sleeve is sleeved with a spring sleeve. The conical sleeve is sleeved with a limiting cushion. A right snap spring is arranged at the left end of the limiting cushion. A limiting pin is arranged on the right side of the spring sleeve. The problem that displacement is prone to happening when force is borne in the axial direction is solved, the turning difficulty is lowered, and the shaving accuracy is improved.

Description

technical field [0001] The invention relates to gear part processing tooling, in particular to a gear part shaving processing jig. Background technique [0002] The existing gear parts shaving fixture adopts light hole centering, because the size of the inner hole fluctuates during turning. When the inner hole size deviates, the positioning gap is too large, resulting in poor gear tooth shape and direction, which affects the gear shaving accuracy. Contents of the invention [0003] In order to solve the problem that existing tooling for gear parts uses a light hole for centering and there is a large positioning gap resulting in poor gear tooth shape and tooth direction, the invention provides a gear part shaving processing jig. [0004] The present invention is realized by adopting the following technical solutions: the gear parts gear shaving fixture includes a left mandrel assembly and a right mandrel assembly arranged between the left and right tops of the gear shaving ...
