Abstract

The invention relates to an epicyclic polishing machine gear ring ascending and descending mechanism, which comprises a gear ring and a center shaft, wherein the gear ring is arranged on a gear ring support frame, the gear ring support frame is fixedly connected with a gear ring sleeve arranged at the lower side, the gear ring sleeve is respectively and fixedly connected with a gear ring gear and a gear ring lifting sleeve, the gear ring lifting sleeve is fixedly connected with a synchronous lifting upper plate arranged at the lower side, the synchronous lifting upper plate is fixedly connected with a synchronous rod arranged at the lower side, the synchronous rod is screwed with a lifting screw nut, the lifting screw nut is axially positioned in a support sleeve through a stop ring and a corresponding shaft via a retainer ring, and is rotationally arranged in a support sleeve through a bearing, the lifting screw nut and the lifting gear are fixedly connected, and the lifting gear is in engaged transmission with a lifting outer gear ring. The epicyclic polishing machine gear ring ascending and descending mechanism has the advantages that the structure is simple, the processing and the assembly are convenient, the ascending and descending transmission precision is high, the reliability is high, and economy and practicability are realized.

Description

technical field [0001] The invention relates to the field of planetary grinding / polishing machines, in particular to a ring gear lifting mechanism of a planetary polishing machine. Background technique [0002] As a star-type double-sided polishing machine, it is necessary for the ring gear to be able to lift and adjust its position. First, it is convenient to pick and place workpieces. Second, it can avoid partial wear of the ring gear and sun gear due to long-term meshing at the same height during processing. Resulting in a rapid shortening of service life. In the existing products, the lifting and lowering methods of the ring gear generally have the following methods: [0003] 1. There are two sets of rollers symmetrically installed on the ring gear lifting sliding sleeve. The rollers can roll on the circumferential end surface. The cam is driven by the crank slider (cylinder) mechanism or the rack and pinion to rotate in a certain angle range, and the circular motion is...
