Abstract

The invention relates to a device for friction and wear test of a sand belt, belonging to the field of mechanical engineering technology, which comprises a driving wheel motor, a contact wheel motor, a driving wheel, a contact wheel, a guide wheel mechanism, a wedge block, a sand belt, a bracket and a base. The driving wheel and the contact wheel are respectively connected with the driving wheel motor and the contact wheel motor, the sand belt is tensioned by the guide wheel mechanism and rounds the guide wheel, the driving wheel and the contact wheel, and the back of the sand belt is in close contact with the guide wheel, the driving wheel and the contact wheel. The wedge block is arranged on the outer circumference surface of the contact wheel. The guide wheel mechanism is arranged on the bracket, and the driving wheel motor, the contact wheel motor and the bracket are arranged on the base. The invention has the simple structure and the easy manufacture, and thereby greatly facilitates preparation and test of a test piece and improves the efficiency of the friction and wear test of the sand belt.

Description

technical field [0001] The invention relates to an experimental device, in particular to a device for abrasive belt friction and wear experiments, which belongs to the technical field of mechanical engineering. Background technique [0002] With the development of machinery manufacturing industry, abrasive belt grinding has become one of the effective methods for precision and ultra-precision machining. Belt grinders are being used more and more widely. However, during the grinding process of the abrasive belt grinder, while the front of the abrasive belt is grinding the workpiece, the back of the abrasive belt is in close contact with the contact wheel. Although there is no abrasive grain on the back of the abrasive belt, the wear of the contact wheel is still serious, which affects the processing efficiency and precision. The higher cost of replacing the contact wheel has become a major bottleneck restricting the development of this type of abrasive belt grinder. The ma...
