Abstract

The invention discloses an RV speed reducer cycloidal-pin wheel tool. The RV speed reducer cycloidal-pin wheel tool comprises a base, a fixing mechanism, a moving mechanism, a grinding wheel mountingmechanism, a grinding wheel, a clamp bracket, a support, clamps, cycloidal-pin wheels and a rotating disc, wherein the cycloidal-pin wheels comprises a cycloidal-pin wheel A and a cycloidal-pin wheelB, and the cycloidal-pin wheel A and the cycloidal-pin wheel B are clamped and positioned by means of the clamp; during machining, a crank bearing through hole of the cycloidal-pin wheel A and a crankbearing through hole of the cycloidal-pin wheel B are aligned with a clamp circular truncated cone A, and the cycloidal-pin wheels are assembled in the clamps; one side of the clamps is kept fixed, the other side drives the cycloidal-pin wheel thereon to rotate by 60 degrees; the two ends of the clamp bracket move oppositely and get close to each other along a guide rail B until a circular truncated cone B of one clamp is inserted into a circumferential through hole of the other clamp; and outer tooth profiles of the cycloidal-pin wheel A and the cycloidal-pin wheel B coincide with each other. The RV speed reducer cycloidal-pin wheel tool can realize reliable clamping and positioning of the cycloidal-pin wheels, and improve the machining precision and the tooth profile consistency of thecycloidal-pin wheels.

Description

technical field [0001] The invention relates to the field of advanced manufacturing equipment and technology, in particular to a cycloidal pin wheel tooling for an RV reducer. Background technique [0002] The RV reducer is widely used in the field of robots. It consists of the front stage of a planetary gear reducer and the rear stage of a cycloidal pinwheel reducer. The RV reducer has compact structure, small vibration, low noise, low energy consumption, and transmission It has the advantages of large ratio and self-locking function under certain conditions. [0003] The cycloidal pin wheel is a key component of the RV reducer. The machining accuracy of its tooth shape directly affects the performance of the reducer. It is required that the tooth profile of the double-piece cycloidal pin wheel have high machining accuracy and ensure consistency. In the prior art, the cycloidal pinwheel is assembled and ground separately, which takes time and effort to process, and it is d...
