A Grinding and Polishing Machine Driving Device with Unreasonable Speed ​​Ratio

Abstract

The invention discloses a grinding polishing machine drive device with the irrational rotating speed ratio. The grinding polishing machine drive device comprises a rack, a driving shaft, a driven shaft, a servo motor for driving the driving shaft to rotate and a grinding disc tray used for supporting a disc; the servo motor is fixed to the interior of the rack, is connected with the driving shaft through a synchronous belt and drives the driving shaft to rotate, and the driven shaft is vertically mounted on the rack; the grinding disc tray is fixed to the upper end of the driven shaft, and the lower end of the driven shaft is connected with the driving shaft through a universal coupler; a 135-degree included angle is formed between the driving shaft and the driven shaft, and when the driving shaft rotates, the driven shaft is driven to rotate through the universal coupler, and therefore a grinding disc fixed to the grinding disc tray is driven to rotate; and the grinding polishing machine drive device is simple and compact in structure, low in production cost and capable of solving the scientific problem of machining path line cycle closing on the basis of the grinding machining kinematic principle. The grinding polishing machine drive device serves as an irrational rotating speed drive device; and compared with the machining precision of a traditional rational rotating speed drive device, the machining precision is greatly improved.

Description

technical field [0001] The invention relates to the field of plane grinding and polishing, in particular to a driving device for a grinding and polishing machine with an unreasonable speed ratio, which is mainly used in the technical fields of electronics, communication, computer, laser, aerospace and aviation. Background technique [0002] High-precision shape control and low-damage shape control are important development directions in the field of abrasive processing. Planar grinding is one of the important means to obtain high-precision surfaces such as optical components, sapphire substrates, and single-crystal silicon substrates. It is widely used in electronics, communications, computers, lasers, aerospace and other technical fields. [0003] Plane grinding must ensure flatness, surface roughness, surface and subsurface dislocation morphology and residual stress, etc. High-precision plane grinding is the necessary basis for ultra-smooth polishing. According to statist...
