摘要： 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.

摘要： An abrasive belt grinding center applicable to grinding and polishing of a whole profile of a blisk is provided, an X-axis feed mechanism, a Y-axis feed mechanism, a Z-axis feed mechanism, a B-axis rotation mechanism and a C-axis rotation mechanism constitute a grinding head feed mechanism, and a housing, a drum, a synchronous driven pulley, a synchronous belt, a synchronous driving pulley, and a grinding head rotation driving motor constitute a grinding head rotation mechanism. In the present application, two grinding heads are utilized to reasonably assign the machining angle and the feeding, and rough machining and fine machining can be both realized by one time of clamping, and the combination of six degrees of freedom in space is achieved by a short drive chain, and further the rigidities of a grinding head mechanism and a workpiece clamping mechanism are ensured. The combination of double grinding heads and a grinding robot can achieve grinding and polishing of the whole profile of the blisk. The contact wheel of the grinding head mechanism and the abrasive belt can go into a small clearance between blades of the blisk, thus can significantly improve the machining efficiency and reduce the management and production costs on the premise of ensuring the machining precision of a complex curved surface and the quality of the profile.
