Abstract

The invention discloses a planet polishing device containing double parallelogram mechanisms. The device comprises a mounting flange, a revolving transmission part, a rotation transmission part and a polishing shaft; a polishing head is arranged at the bottom of the polishing shaft; the revolving transmission part is a plane connecting rod mechanism containing double parallelograms for realizing revolving motion of the polishing shaft; the rotation transmission part is driven by a two-grade synchronous tooth belt to realize rotation motion of the polishing shaft; and the mounting flange is fixed on a shell of the revolving transmission part, and can be mounted on different equipment. The planet polishing device can adjust the revolving radius according to different polishing process demands; a rotation motor is mounted on the shell of the revolving transmission part without participating in the revolving motion, so that the inertia force can be effectively reduced; and the revolving transmission part is provided with a balance counterweight for part balance of the inertia force generated by a mechanism motion part, so that the performance of the planet polishing device is further improved.

Description
