Abrasive belt grinding machine

Abstract

The invention relates to an abrasive belt grinding machine used for grinding and polishing workpieces. The abrasive belt grinding machine comprises a body, a grinding head assembly and a grinding head adjusting mechanism, wherein the body is used for bearing the workpieces; the grinding head assembly is installed on the body and comprises an abrasive belt, a driving wheel, a support plate and a grinding head driving part; the abrasive belt is wound around the driving wheel and the support plate; the support plate comprises a support body and a contact wheel; the support body comprises a first end aimed at the workpieces; a housing groove is formed at the first end; the contact wheel can be installed in the housing groove in a rotary manner; an outer circumferential surface of the contact wheel protrudes relative to the housing groove; the outer circumferential surface, exposed out of the housing groove, of the contact wheel comes into contact with the inner side of the abrasive belt; the grinding head driving part is matched with the driving wheel to drive the driving wheel to rotate; and the grinding head adjusting mechanism is used for adjusting the distances between the adhesive belt and the workpieces in a first direction and a second direction.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an abrasive belt grinder for grinding and polishing workpieces such as vanes and blades. Background technique [0002] Abrasive belt grinder is a device that uses a fast-moving abrasive belt as an abrasive to grind and polish blades and blades. With the rapid development of grinding machine technology, abrasive belt grinding machines have developed into high-efficiency and low-power finishing equipment. Due to the limitations of the grinding machine mechanism and workpiece installation structure, the grinding and polishing of workpieces with complex geometric shapes, such as aviation blades and steam turbine blades, are generally done manually. Although manual grinding can realize the grinding and polishing of complex curved surfaces, due to the subjective influence of people, the quality of the curved surface surface is determined by the proficiency of the operator, so it i...

AI Technical Summary

Problems solved by technology

Although manual grinding can realize the grinding and polishing of complex curved surfaces, due to the subjective influence of people, the quality of the curved surface surface is determined by the proficiency of the operator, so it is impossible to effectively control the dimensional accuracy of the workpiece, resulting in poor processing accuracy. The surface quality is difficult to guarantee, and even the grinding thickness is uneven in the surface polishing, and the product consistency is difficult to guarantee; at the same time, the labor intensity of the workers is high and the processing efficiency is low
