An abrasive belt grinding device suitable for the grinding and polishing of the overall blisk blade surface and the intake and exhaust edges

Abstract

The invention discloses an abrasive belt grinding device which is suitable for grinding and polishing the profiles of integral blisk blades and the edges of intake and exhaust. The device mainly includes: mounting flange, idler pulley, tension mechanism, driving pulley, contact pulley mechanism, grinding force control mechanism, grinding head support plate, spindle motor, etc., idle pulley, tension pulley, contact pulley and drive The wheel is fixed on the support plate of the grinding head through a rigid shaft, the main shaft motor drives the driving wheel to realize the high-speed movement of the abrasive belt, and the floating cylinder controls the tension wheel to realize the tension of the abrasive belt; the contact wheel is installed on the contact wheel bracket, and the contact wheel bracket passes through It is installed on the support plate of the grinding head in a hinged manner, and its end is connected with the output end of the precision servo electric cylinder. The swing of the contact wheel bracket and the control of the grinding force are realized through the promotion of the servo electric cylinder. The structure design of the invention is ingenious, and the grinding and polishing are flexible It is highly versatile, highly versatile, easy to integrate on CNC machine tools, greatly reduces production costs, and has good practical and promotional value.

Description

technical field [0001] The invention belongs to the field of aviation manufacturing, and relates to the manufacture of integral blisk parts of aero-engines, in particular to an abrasive belt grinding device for realizing the grinding and polishing of integral blisk blade profiles and intake and exhaust edges.
