Problems solved by technology

[0002] The existing grinding wheel spindle inclination adjustment structure adopts a three-point adjustment method, that is, the angle between the grinding wheel spindle and the horizontal plane is determined after adjusting the heights of the three points respectively. During the adjustment, the height of the three points must be adjusted separately, and the adjustment is more complicated, and because the existing adjustment The structure is a strut structure, the stability is relatively low, and the resolution of its adjustment is low, and because the adjustment structure is generally located at the bottom of the spindle seat, manual adjustment is inconvenient

Abstract

The invention relates to a grinding wheel spindle inclination angle adjusting structure, which has the advantages of simple and convenient adjustment, high stability and high adjustment resolution. The structure comprises a grinding wheel spindle, a grinding wheel, a spindle seat and three supporting feet, wherein the grinding wheel is fastened at the lower end surface of the grinding wheel spindle, and the grinding wheel spindle is connected with the spindle seat via the three supporting feet uniformly distributed on the circumference of a grinding wheel spindle flange. The invention is characterized in that one of the three supporting feet is an adjustable supporting foot, the other two supporting feet are fixed supporting feet, two heads of a double-head screw of the adjustable supporting foot are respectively connected and fastened to connectors on the grinding wheel spindle flange and the spindle seat, and the screw pitches at both heads of the double-head screw are not equal.

Description

(1) Technical field [0001] The invention relates to the technical field of semiconductor wafer processing equipment, in particular to a grinding wheel main shaft inclination angle adjustment structure. (2) Background technology [0002] The existing grinding wheel spindle inclination adjustment structure adopts a three-point adjustment method, that is, the angle between the grinding wheel spindle and the horizontal plane is determined after adjusting the heights of the three points respectively. During the adjustment, the height of the three points must be adjusted separately, and the adjustment is more complicated, and because the existing adjustment The structure is a strut structure with relatively low stability and low adjustment resolution, and because the adjustment structure is generally located at the bottom of the main shaft seat, manual adjustment is inconvenient. (3) Contents of the invention [0003] In view of the above problems, the present invention provides...
