Title:
ABRASIVE BELT GRINDING DEVICE FOR PROFILE PRECISION CONSISTENCY
Document Type and Number:
WIPO Patent Application WO/2018/000747
Kind Code:
A1
Abstract:
An abrasive belt grinding device for profile precision consistency. A support plate passes through an inner cylinder and fixed to the inner cylinder; the inner cylinder is rotatably connected with an outer cylinder support; a winding wheel and an unwinding wheel are provided side by side at the upper end of the support plate; the winding wheel and the unwinding wheel are driven by respective first servo motors; one end of an abrasive belt is wound in the groove of the winding wheel, and the other end of the abrasive belt passes by a first transition wheel, a first tension wheel, a third transition wheel, a fifth transition wheel, a seventh transition wheel, a contact wheel, an eighth transition wheel, a sixth transition wheel, a fourth transition wheel, a second tension wheel, and a second transition wheel, and is finally wound in the groove of the unwinding wheel. The present invention can switch the winding wheel and the unwinding wheel between winding and unwinding by means of forward and reverse rotating of the servo motors, so that the abrasive belt can perform grinding in a reciprocating manner. Torque control can be performed on the tension force of the abrasive belt by the motors, so that the tension force can be kept constant, the precision and surface quality of the ground workpiece can be improved, and faults, such as belt breakage, during grinding can be reduced.
