Abrasive Belt Grinding Device Oriented to Surface Accuracy Consistency

Abstract

An abrasive belt grinding device for profile precision consistency is provided, a supporting plate passes through an inner cylinder, and is fixed to the inner cylinder, the inner cylinder is rotatably connected to an outer cylinder bracket, a winding reel and an unwinding reel are arranged side by side in a left-right direction at an upper end of the supporting plate, and are driven by respective first servo motors arranged corresponding to the winding reel and the unwinding reel, one end of the abrasive belt is wound in a belt groove of the winding reel, and another end of the abrasive belt is wound over the first transition wheel, the first tension pulley, the third transition wheel, the fifth transition wheel, the seventh transition wheel, the contact wheel, the eighth transition wheel, the sixth transition wheel, the fourth transition wheel, the second tension pulley, and the second transition wheel, and is finally wound in a belt groove of the unwinding reel. In the present application, the switching between winding and unwinding of the winding reel is achieved by forward and backward rotations of the servo motors, and thus the abrasive belt can perform grinding process reciprocatingly. The tensile force of the abrasive belt can be adjusted by controlling a torque of the motor, thus the tensile force can be ensured to be constant, the precision and surface quality of the ground workpiece can be improved, and also the failures such as breakage of belt in the grinding process can be reduced.

Description

technical field [0001] The invention belongs to the field of flexible abrasive belt grinding, and in particular relates to an abrasive belt grinding device oriented to the consistency of profile precision. Background technique [0002] Thin-walled components such as blisks, aeroengine blades, and steam turbine blades are key functional structural parts of aircraft and ships. The processing and manufacturing level of these parts directly determines the development of aerospace, navigation and other industries. On the one hand, these thin-walled components have complex curved surfaces, which makes it difficult to realize automatic processing; on the other hand, the processing accuracy and surface quality of key components such as blisks are high, and surface quality problems such as surface burns and defects must be avoided. In addition, it is also necessary to ensure processing efficiency. [0003] Thin-walled components such as blisks are mainly made of materials with high ...

Problems solved by technology

In terms of engineering, grinding and polishing grinding heads that fully meet these needs have not been applied in China, which largely limits the promotion, use and development of multi-axis CNC grinding machines.
