Grinding machine and method for grinding and changing abrasive belts of the grinding machine

Abstract

The invention provides a grinding machine and a grinding and abrasive belt replacing method thereof. Through the grinding machine and the grinding and abrasive belt replacing method thereof, the problems that an existing grinding machine is low in grinding efficiency and abrasive belts are wasted are solved. The grinding machine comprises a grinding module, a first rotary disk and a second rotarydisk which are mounted on a mounting plane at intervals. Rotary shafts of the first rotary disk and the second rotary disk are perpendicular to the mounting plane. An unused abrasive belt is arrangedon the outer side of the first rotary disk in a surrounding mode. The outer side end of the abrasive belt passes around the grinding surface of the front end of the grinding module to be connected with the second rotary disk. The second rotary disk and the first rotary disk rotate to drive the abrasive belt on the grinding surface to move from the first rotary disk to the second rotary disk and bearranged around the outer side of the second rotary disk. The grinding machine further comprises a first clamping me arranged between the first rotary disk and the grinding module and a second clamping mechanism arranged between the second rotary disk and the grinding module. The first clamping mechanism and the second clamping mechanism are used for fixing or loosening the abrasive belt betweenthe first and second rotary disks and the grinding module. The abrasive belt can be replaced automatically. Waste of abrasive belts can be reduced. The grinding efficiency can be improved.

Description

technical field [0001] The invention relates to grinding equipment, in particular to a grinding machine and a grinding and abrasive belt changing method of the grinding machine. Background technique [0002] Grinding, deburring and polishing the surface of the workpiece is an important process in machining, which can effectively improve the quality and service life of the workpiece. In small batch processing and production, the workpiece can be polished manually, but this kind of grinding operation has high requirements on the skills and physical strength of the operator, and the quality of the workpiece polished by different operators is quite different. , lower production efficiency. Therefore, there has been a grinder with an abrasive belt in the prior art to grind the workpiece. [0003] Grinding machines in the prior art usually include a driving wheel, a driven wheel, an abrasive belt and a grinding head. The unused abrasive belt is wound around the outside of the dr...

AI Technical Summary

Problems solved by technology

To replace the abrasive belt on the grinding surface in this way, the operator needs to turn the handle according to experience, and there will be problems of excessive movement of the abrasive belt and waste of abrasive belt, or too little rotation and too little movement of the abrasive belt, which will affect the effect of grinding. , and the abrasive belt on the grinding surface is replaced by the hand handle, the replacement efficiency is low, which affects the grinding efficiency of the workpiece
