To achieve these goals, the utility model provides a kind of swing type grinding head for polishing, comprise: main shaft, abrading block seat, differential gear, swing mechanism and damper mechanism, described main shaft rotates by the driving gear that key drives drive sleeve and described differential gear respectively, and described swing mechanism comprises fork, swinging axle and swing seat;

Described swing mechanism also comprises:

The inclined shaft cover is movably arranged on the drive sleeve, and adopts key to fixedly connected with the driven gear of described differential gear;

Rotating disk is movably arranged on described inclined shaft and puts;

Last item is installed on the rotating disk;

Described damper mechanism comprises:

The first vibration damping rubber cushion is arranged on the lower end of drive sleeve;

The second vibration damping rubber cushion is arranged on the upper end of drive sleeve.

By above technical scheme as can be known, the utility model swing type grinding head for polishing has following advantage: simplified swing mechanism; Isolated the vibration that produces in the polishing process, reduced impact main shaft; Prolong the service life of bistrique, reduced the spoilage of part.

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
