Upper disc device of double-side grinding machine

Abstract

The invention discloses a double-sided grinder upper disc device, which comprises a frame provided with a first driving device, a moving bracket arranged on the frame and driven by the first driving device to slide up and down along the frame, The main shaft, which is driven to rotate by the second driving device, and the upper plate assembly, which is movably connected with the main shaft through joint bearings, are arranged on the moving support. The present invention has its own driving structure, which reduces the difficulty of manufacturing and processing the lower transmission main body and improves the precision of the equipment. The lifting and lowering of the upper plate and the pressurization are realized by the movement of the moving bracket driven by the cylinder on the linear slide rail, which solves the problem of unstable transmission and large vibration of the traditional upper plate device. The upper plate device adopts the joint bearing structure, so that the upper plate can be automatically fitted according to the working conditions of the lower plate, which effectively solves the problem of poor bonding of the upper plate and lower plate caused by the level difference of the lower plate, and improves the machining accuracy.

Description

technical field [0001] The invention belongs to a high-precision double-side grinding machine, and in particular relates to a top plate device of a double-side grinding machine. Background technique [0002] The traditional double-sided grinding machine adopts a planetary motion mechanism, and the upper plate, lower plate, ring gear and sun gear are all driven by the lower transmission body. The equipment manufacturing and maintenance are complicated, and the vibration is relatively large, and the processing accuracy is low. In particular, the weight of the upper plate device is directly borne by the cylinder, which drives the upper plate to move up and down through the connecting joint, the transmission is not stable, and it is easy to cause local impact during the pressurization process, resulting in damage to the ceramic workpiece. Contents of the invention [0003] The object of the present invention is to address the defects of the prior art, and provide a self-driven...
