Polishing grinding head

Abstract

The invention relates to a polishing grinding head, comprising a grinding disc and a grinding head installation structure, wherein a cylindric lower grinding seat, a cylindric middle grinding seat and a cylindric upper grinding seat are successively arranged on the upper part of the grinding disc; the lower end of the lower grinding seat, the upper end of the middle grinding seat and the lower end of the upper grinding seat are respectively provided with a flange plate, the grinding disc is connected with the flange plate of the lower grinding seat by bolts, the cylindric lower grinding seat is externally nested on the cylindric middle grinding seat and is in transmission connection by a fastening device, and an elastic connecting device is arranged between the flange plate of the cylindric middle grinding seat and the flange plate of the cylindric upper grinding seat. The elastic connecting device is arranged between the flange plate of the upper grinding seat and the flange plate of the middle grinding seat, so that the flange plates can automatically change the inclined angles of the grinding disc along with the shapes of processed workpieces so as to adapt to the processing of the cambered workpieces with uneven surfaces; and the grinding head can reduce the processing noise and increase the percent of pass of products.

Description

Technical field: [0001] The invention relates to a grinding and polishing equipment, in particular to a polishing grinding head assembled on the driving mandrel of an automatic continuous polishing machine and used for various thin plate materials such as granite, marble, glass-ceramic and tiles. Background technique: [0002] The polishing grinding head used for surface processing of various thin plate materials such as granite, marble, glass-ceramics, ceramic tiles, etc. is mainly composed of a grinding disc with a grinding disc and its connecting mechanism. When in use, the grinding disc is installed on the polishing drive through the connecting mechanism. on the mandrel. [0003] The connection between the grinding disc and the transmission mandrel of the traditional polishing grinding head is a rigid connection. During processing, the grinding disc and the surface of the workpiece are in line contact. Therefore, the traditional polishing grinding head is only suitable f...

AI Technical Summary

Problems solved by technology

Therefore, although the contact surface between the joint of the drive mandrel and the joint seat of the grinding disc is a hemispherical surface, the grinding disc can only swing left and right around the axis of the bayonet pin, and it is difficult to realize arbitrary swing with multiple degrees of freedom, and it is also difficult to effectively polish uneven surfaces. processing

The technical solution also has the disadvantages of high noise and high breakage rate
