A fast-clamping and self-aligning grinding wheel flange for precision grinding machines

Abstract

The utility model relates to a fast-clamping and self-aligning grinding wheel flange for a precision grinding machine, which relates to the field of precision grinding. Equipped with machine tool spindle, grinding wheel fixing nut, grinding wheel, self-aligning wrench, jaws, back end of centering device back cover, small bevel gear, front end of centering device back cover, centering device front cover, ball cover, bearing, large cone Gears and balls; first, install the statically balanced grinding wheel flange into the taper front end of the machine tool spindle, and pre-tighten it with the grinding wheel fixing nut, then insert the self-aligning wrench into the self-aligning hole of the flange, and the self-aligning wrench passes through the small bevel gear and The gear transmission of the large bevel gear drives the large bevel gear to rotate. At the same time, the feed movement of the claw is realized through the rack transmission between the plane thread on the large bevel gear and the claw. The claw that moves in three directions at the same time grasps the machine tool spindle to solve The problem of eccentricity between the center of the grinding wheel and the axis of the machine tool spindle is solved. The structure is simple, economical and reliable, and the clamping of the grinding wheel is realized; the eccentricity error in the assembly of the grinding wheel is effectively overcome.

Description

technical field [0001] The invention relates to the field of precision grinding, in particular to a fast-clamping and self-aligning grinding wheel flange for a precision grinding machine. Background technique [0002] As the precision manufacturing industry has higher and higher requirements for the surface processing accuracy of optical components, the installation accuracy of the grinding wheel has also become a factor that cannot be ignored. The control of the installation error of the grinding wheel has become the primary problem of high-precision grinding machine tools. There are roughly the following reasons for the installation error of the grinding wheel, including the roundness error of the grinding wheel and the coaxiality error of the grinding machine spindle, which are generally relatively small; the most important influencing factor is the eccentricity error caused by the installation eccentricity between the center of the grinding wheel and the axis of the spind...

AI Technical Summary

Problems solved by technology

[0003] At present, there are few researches on the fine-tuning technology of grinding wheels at home and abroad. The current installation of grinding wheels is mainly to clamp the grinding wheel with a fixture, then assemble it on the machine tool spindle, and manually adjust the concentricity. It is difficult to find the concentric position, and It is very time-consuming; you can also use the control method to eliminate the eccentricity error through the control software. The disadvantage of this method is that the preparation work is very cumbersome and relatively complicated
