Wet automatic grinding and polishing machine

Abstract

The invention relates to a wet automatic grinding and polishing machine. A grinding machine is installed on a moving device, the moving device is installed on a base, and the base, the moving device and the grinding machine are all located in a housing; the housing is a full-closed shell, and an automatic door is arranged on the housing; a workpiece fixing device and a sand disc assembling deviceare installed at the two ends of a double-station rotary exchange platform correspondingly, the double-station rotary exchange platform and a sand disc disassembling device are both fixed to the base,and a grinding control device is installed between the grinding machine and the moving device; and a circulating filtration device is installed under the base, a universal cooling pipe is installed on the housing, the base is further provided a water outlet, and the water outlet is connected with the circulating filtration device. The wet automatic grinding and polishing machine has the full-closed grinding machine body structure, adopts a wet grinding mode and is high in safety; and in addition, a full-closed loop force feedback grinding pressure control system is adopted, the grinding forceand the rotation speed can be precisely controlled, the smooth and even surface effect can be formed, the sand disc replacement speed is high, and the filter material using rate is high.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a wet automatic grinding and polishing machine. Background technique [0002] Existing automatic grinding machines mostly use a combination of cylinders to move the grinding machine. The grinding control accuracy is not high, the surface quality of the grinding parts is poor, and the grinding pressure cannot be controlled, which is prone to over-grinding, resulting in unqualified products. There is also a serious wear of the grinding sheet, which causes the workpiece after grinding to fail to meet the grinding requirements and needs to be reworked. The speed of the grinding machine cannot be controlled, and the rotational speed is uneven, which cannot meet various grinding needs. [0003] Most of the existing automatic grinding machines use a semi-open body structure. Since they do not have a fully enclosed cover structure, the dust generated during the grinding process is easy to disperse ...

AI Technical Summary

Problems solved by technology

The existing grinding fluid filter devices mostly use a single piece of filter paper, which needs to be replaced manually at regular intervals, and workers tend to forget to replace it, which affects the processing quality, and the efficiency of manual replacement is poor and takes a long time

Existing filtration uses more than one filtration, the filtration effect is poor, and the use efficiency of grinding fluid is low
