Abrasive band grinding device used for complex curved surface

Abstract

The invention discloses an abrasive band grinding device used for a complex curved surface. The abrasive band grinding device comprises an X-axis lathe bed, a Y-axis lathe bed, a Z-axis lathe bed, a working table assembly, a grinding head base and a grinding head assembly. According to the abrasive band grinding device, an abrasive band is wound on a unrolling wheel, a rolling wheel, a contact wheel and middle transition wheels, and under the combined action of the wheels, the abrasive band can generate grinding motion at a certain speed. A six-axis linkage mode is used for driving the contact wheel, grinding machining can be performed on an aviation engine blade of a complex curved surface structure and other workpieces of complex curved surface structures in the longitudinal direction and the transverse direction under the condition that the workpieces perform only feeding motion, grinded patterns generated by the grinding machining in the longitudinal direction can improve fatigue strength and other mechanical properties of the workpieces, and therefore a good machined result is obtained. Through the six-axis linkage control mode, other parts of the workpieces of the complex curved surface structures can be further machined, wherein the other parts comprise blade roots, the edges of curved surfaces and others.

Description

technical field [0001] The invention belongs to the technical field of abrasive belt grinding, and in particular relates to an abrasive belt grinding device for complex curved surfaces. Background technique [0002] Abrasive belt grinding technology is a technology that uses the abrasive belt for grinding movement as an abrasive tool to grind and polish the surface of the workpiece. It is an elastic processing and has many incomparable advantages compared to other processing methods. On the one hand, it has an irreplaceable role. With the rapid development of abrasive belt grinding technology and devices, abrasive belt grinding machine tools have developed into a finishing equipment with high processing efficiency, strong adaptability, wide application range, low cost of use, and safe and convenient operation. Especially for the processing of thin-walled structural parts with complex curved surfaces such as aeroengine blades, the grinding process of small-sized complex prof...
