In-place finishing device and method for air bag polishing head

Abstract

The invention discloses an in-place finishing device and an in-place finishing method for an air bag polishing head. The in-place finishing device comprises an in-place sharpening device and an optimal machine tool body moving part, wherein the air bag polishing head is spherical-crown-shaped; the whole sharpening device is connected with a vertical column of a machine tool through a sharpening base; two parallel guide rails are arranged on the sharpening base; a grinding wheel spindle is arranged in a grinding wheel spindle box; the grinding wheel spindle box is erected on a bottom plate; the bottom plate is movably connected with the guide rails through sliding blocks; an air cylinder is arranged between the two guide rails; the tail end of a piston rod of the air cylinder is in transmission connection with the sliding blocks; a grinding wheel with circular-arc-shaped section is arranged at the output end of the grinding wheel spindle; a sharpening motor is in transmission connection with the other end of the grinding wheel spindle; the machining surface of the grinding wheel movably abuts against the surface of a polishing cushion of the air bag polishing head. By virtue of the self-movement of the polishing machine tool, in-place finishing can be realized. The in-place finishing device is simple in structure, low in cost, easy to operate and ideal in using effect; influence on finishing accuracy and polishing accuracy caused by repeated disassembly of the air bag polishing head can be avoided.

Description

technical field [0001] The invention relates to polishing technology, in particular to a trimming device of an in-position airbag polishing head on an airbag polishing machine and a method for trimming the airbag polishing head through the rotation and translation of the polishing machine itself. Background technique [0002] Airbag polishing technology is a polishing method proposed in the 1990s, especially suitable for polishing curved surfaces. The airbag polishing technology uses a spherical airbag with a certain inflation pressure as a polishing tool. The material of the airbag is rubber, the inside of the airbag is inlaid with nylon rope or iron sheet, and the surface of the airbag is pasted with a polishing pad. When the inflation pressure of the airbag is different, the deformation of the airbag is different, and when the thickness of the polishing pad is uneven, the radius of curvature of the outer surface of the polishing pad is also different; at the same time, as...

AI Technical Summary

Problems solved by technology

[0007] (2) The preparatory work for repairing is cumbersome;

[0008] (3) When the ball center of the airbag is not on the axis of the swing shaft, there is a large trimming error and the polishing accuracy is low;

[0009] (4) It is the rubber airbag that is repaired, rather than the polishing pad on the surface of the airbag, and the polishing accuracy is low;

[0010] The effect of trimming is not ideal enough
