Constant-force polishing device

Abstract

The invention relates to a constant-force polishing device which comprises a proportional control valve, an electromagnetic valve and an air cylinder, the proportional control valve is connected with the air cylinder through the electromagnetic valve, the constant-force polishing device further comprises a connecting base, a guide support, a lifting support, a polishing base, a control panel and a telescopic dust cover, and the guide support, the proportional control valve and the air cylinder are all fixed to the connecting base; the lifting supports are slidably installed on the guide support and located on the two sides of the air cylinder. The grinding seat is fixed on the lifting bracket; the control panel is fixed on the connecting seat or the guide bracket; the control panel is electrically connected with the proportional control valve and the electromagnetic valve; the two ends of the telescopic dust cover are connected with the connecting base and the grinding base correspondingly. According to the constant-force grinding device, the distance between the grinding wheel and the surface of a workpiece can be adjusted in real time, constant-force grinding is achieved, the grinding quality is stable and reliable, the requirement for the consistency of the workpiece is lowered, the grinding efficiency is improved, early-stage preparatory work is reduced, and the grinding cost is reduced.

Description

technical field [0001] The invention relates to a grinding device, in particular to a constant force grinding device. Background technique [0002] In order to improve the grinding efficiency and grinding quality, more and more manipulators are used for grinding. When grinding, the manipulator grinds the workpiece according to the preset grinding trajectory. This grinding method has high requirements on the consistency of the workpiece, and the size deviation of the workpiece should not be too large. For example, if the size is too large, the pressure on the manipulator during grinding will be high, which is easy to damage the manipulator, and the size is too small to be polished. And along with the wearing and tearing of grinding wheel, the distance between grinding wheel and workpiece becomes bigger, but grinding track is set according to constant grinding distance, causes the quality of grinding after grinding wheel wears and does not meet the requirement.

Problems solved by technology

This grinding method has high requirements on the consistency of the workpiece, and the size deviation of the workpiece should not be too large. For example, if the size is too large, the pressure on the manipulator during grinding will be greater, which will easily damage the manipulator. If the size is too small, it will not be polished.

And with the wear of the grinding wheel, the distance between the grinding wheel and the workpiece becomes larger, but the grinding track is set according to a constant grinding distance, which causes the quality of grinding after the grinding wheel is worn to not meet the requirements
