Blade full characteristic robot grinding and polishing device

Abstract

The invention belongs to the field of complex surface manufacturing, and discloses a blade full characteristic robot grinding and polishing device. The blade full characteristic robot grinding and polishing device comprises a self-adaption abrasive belt grinding and polishing mechanism, a contact wheel type abrasive belt grinding and polishing mechanism and a self-adaption abrasive wheel grindingand polishing mechanism which ground and polish the positions including the blade backs, the blade basins, damping tables and blade root corners of blades, and blade full characteristic grinding and polishing are accordingly achieved; and each mechanism comprises a connecting flange, a voice coil motor, a force sensor, a motor and a polishing module, wherein the voice coil motor is arranged on theconnecting flange and is connected with the force sensor through a sliding block, the force sensor is connected with the polishing module to be used for measuring the actual polishing force of the polishing module, the motor is connected with the polishing module to be used for driving the polishing module, and the connecting flange is used for connecting the grinding and polishing device with anexternal robot. By means of the blade full characteristic robot grinding and polishing device, variable force grinding and polishing according to different grinding allowances is achieved, meanwhile,blade surface full characteristic grinding and polishing are achieved, the force feedback and response speed is high, and the grinding and polishing accuracy is high.

Description

technical field [0001] The invention belongs to the field of complex curved surface manufacturing, and more specifically relates to a blade full-feature robot grinding and polishing device. Background technique [0002] The surface quality and surface accuracy of blades have a great influence on the airflow dynamics and performance of aero-engines, gas turbines, and steam turbines. Improving the machining accuracy of blade surfaces is one of the important measures to improve their quality. The curved surface of the blade is relatively complex, and the blade body has a large degree of distortion. It is difficult for ordinary machine tools to finish the surface of the blade. At present, some developed countries have made outstanding achievements in the development of automatic grinding and polishing processing equipment for complex curved surfaces of blades. CNC abrasive belt grinders and robotic grinding and polishing systems have been widely used in industrial production. A...
