Example Embodiment

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] like figure 1 As shown, the gap adaptive polishing grinding head of the present invention includes a connecting piece 1 , a flexible spiral tube 3 , a guide column 4 , a spring 5 , a grinding head seat 7 , a retaining ring 8 and a grinding head body 9 . Wherein, the materials of the connecting piece 1 , the guide column 4 and the grinding head seat 7 are all duralumin alloys. A threaded hole is opened above the connecting piece 1 to facilitate connection with the spindle of the machine tool, and an O-ring 2 is placed at the threaded undercut to ensure that the polishing liquid does not leak. The number of the guide columns 4 is 3, and they are placed at equal intervals of 120° on the circumference, and the fixing method with the connecting piece 1 is interference connection. The spring 5 is a compression spring and is sleeved on the outside of the gu...

Abstract

The invention discloses a gap self-adaptive polishing grinding head, which belongs to a polishing grinding head involved in the optics cold processing field, and aims at solving the problem when the present grinding head is used for polishing, the polishing liquid is non-uniform and a gap between the grinding head and a work-piece is overlarge. The gap self-adaptive polishing grinding head comprises a connection element, a gasket ring, a flexible helical pipe, a guide column, a spring, a retainer ring, a grinding head seat and a grinding head body. The gap self-adaptive polishing grinding head can be connected with a machine tool, the polishing liquid flows into the grinding head through an inner hole of a machine tool main shaft and is continuously supplied to the grinding head body through the flexible helical pipe. When in polishing, the grinding head body is firstly used for pressing the surface of the work-piece, so the spring is slightly compressed, when the surface of the work-piece is fluctuated or error appears in the installation and positioning, and the grinding head body can move from top to bottom along the guide column so as to automatically compensate the gap and to guarantee the polishing quality.

Description

technical field [0001] The invention relates to the technical field of optical cold processing, in particular to a gap self-adaptive polishing grinding head. Background technique [0002] The polishing process is the last link in optical cold processing. In the polishing process, the polishing mold is usually attached to the surface of the workpiece, and at the same time, high-speed relative motion is performed to generate a large tangential force, so that the tiny protrusions on the glass surface are cut, thereby gradually forming a smooth surface. [0003] The disadvantage of using a solid grinding head for polishing in traditional optical processing is that the polishing liquid is not uniform under the grinding head during polishing and is not easy to renew, and even the local polishing liquid cannot be obtained during rapid polishing. Patent ZL200410011215.X proposes to solve this problem by using a hollow grinding head and spraying liquid in the center, so that the pol...
