Free-form surface grinding and polishing device for micro-sized special-shaped precision parts

Abstract

The invention discloses a free-form surface grinding and polishing device for micro-sized special-shaped precision parts. The free-form surface grinding and polishing device comprises a base, two lifting vertical plates, a vertical plate driving mechanism, a rotating worktable, a vibration-damping support mechanism, a grinding mechanism and an angle adjusting mechanism; the two lifting vertical plates are arranged oppositely on both sides above the base; the lower ends of the lifting vertical plates are elastically and movably connected with the base; the vertical plate driving mechanism drives the two lifting vertical plates to move up and down simultaneously; the bottom of the rotating worktable is adjustably and fixedly connected with a gear box; and the grinding mechanism is located above the rotating worktable, and is adjustably and fixedly connected to the two lifting vertical plates through the angle adjustment mechanism and the vibration-damping support mechanism. A friction disc accurately moves according to a predetermined trajectory, the grinding and polishing pressure is accurately controlled, the posture adjustment is stable and flexible, and variable, the impact of vibration on the processing quality is eliminated, higher processing accuracy and surface quality are obtained, the degree of automation is high, the production efficiency is improved, and the consistency of processing quality is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a free-form surface grinding and polishing device for small and special-shaped precision parts. Background technique [0002] With the rapid development of related technologies such as computer technology and automatic control theory, the flexible manufacturing technology represented by numerical control machining is becoming more and more perfect. The processing still needs to be done manually by the workers, which will inevitably increase the labor intensity of the workers, reduce the production efficiency, and cannot guarantee the consistency of the processing quality, which makes the finishing and finishing of the workpiece a weak link in mechanical processing, and even a manufacturing industry. development bottleneck. [0003] At present, the use of robots for free-form surface grinding and polishing is one of the main methods of finishing automation...
