Inner and outer gear lifting system of planetary gear type two-sided lapping/polishing machine

Abstract

The invention discloses an inner and outer gear lifting system of a planetary gear type two-sided lapping / polishing machine. The inner and outer gear lifting system comprises a control circuit and a lifter driven by a motor through a lifting driving gear. The control circuit comprises a motor forward and reverse rotation control circuit, an upper limit proximity switch, a lower limit proximity switch, a circle counting proximity switch, a circle counting sensing board and a lifting sensing board. The lifting sensing board is fixed on the lifter, and the circle counting sensing board is mounted and fixed on the lifting driving gear. The signal output end of the upper limit proximity switch, the signal output end of the lower limit proximity switch and the signal output end of the circle counting proximity switch are connected with corresponding control signal input ends of a controller of the motor forward and reverse rotation control circuit. According to the inner and outer gear lifting system, the height of an inner gear and an outer gear can be conveniently adjusted, and the adjusting process can be carried out anytime; parts do not need to be dismounted in the adjusting process, and equipment assembling precision cannot be changed so that stability of a machine tool in long-time work can be guaranteed; abrasion of the inner gear and the outer gear is even, and the service life is greatly prolonged.

Description

[technical field] [0001] The invention relates to a grinding machine or a polishing machine, in particular to an internal and external gear lifting system of a planetary gear type double-sided grinding / polishing machine. [Background technique] [0002] The double-sided grinding / polishing machine is very suitable for simultaneous grinding and polishing of the upper and lower parallel end faces of thin precision parts of hard and brittle materials. It can process thin parts with very high requirements for flatness, equal thickness and roughness, so It has been widely used in the processing fields of optics and semiconductor materials. [0003] Such as figure 1 with figure 2 As shown, the traditional double-sided grinding (polishing machine) adopts a planetary gear train transmission structure, including a frame, a sun gear 10, an inner ring gear 11, a lower grinding disc 12, an upper grinding disc 40, a planetary gear 41, and a sun gear driving mechanism , Drive mechanism ...

AI Technical Summary

Problems solved by technology

[0007] The wear of the meshing part of the sun gear and the inner ring gear of the double-sided grinding machine (polishing machine) has always been the main problem in the maintenance of the double-sided grinding machine equipment. The adjustment of the height of the sun gear and the inner ring gear is also labor-intensive and time-consuming maintenance operation, and It may also cause a decline in the yield of processed parts due to poor adjustment and assembly of the sun gear or ring gear
