AI Technical Summary

Technical Problem

The existing internal spline gear grinding tooling requires manual rotation of the nut during operation, which is laborious, especially for internal spline gears with larger sizes and weights, which are difficult to operate manually.

Method used

The inner flower bond gear grinding tooth workers driven by the hydraulic system are used to provide a tightening force through the hydraulic cavity and slider mechanism to automatically complete the positioning and clamping of the inner flower bar gear.

Benefits of technology

It reduces the difficulty of operation and saves effort. The hydraulic system can provide sufficient tightening power to ensure the stable positioning of the inner flower bond gear, and the tightening force is uniform, which improves the positioning accuracy.

Abstract

The internal spline gear grinding tool comprises a positioning seat, a rotating disc is arranged on the positioning seat, and the rotating disc is connected with a second driving mechanism for driving the rotating disc to rotate; a positioning disc is fixedly arranged on the upper surface of the rotating disc, and a hydraulic cavity is formed in the positioning disc and connected with a hydraulic system; a stepped hole is formed in the inner wall of the hydraulic cavity and comprises a first square hole and a second square hole, a sliding block is arranged in the second square hole and is in sliding fit with the inner wall of the second square hole, and an elastic sealing gasket is arranged between the sliding block and the hole bottom of the second square hole; the sliding block is fixedly connected with tensioning teeth, and the tensioning teeth penetrate through the first square hole and are in sliding fit with the inner wall of the first square hole. The hydraulic system is adopted for providing tensioning force for the tensioning teeth, manual operation is not needed, the operation difficulty is lowered, more labor is saved, the hydraulic system can provide the tensioning force large enough, and it is guaranteed that the internal spline gear is stably positioned.
