Problems solved by technology

This limits the use of this grinding head to those surfaces with small curvatures, such as surfaces with deep "canyon" shapes or surfaces with sharp changes in shape.
Furthermore, when processing some sharp and thorny surfaces, the film is easily damaged, making the internal air pressure unstable, thus affecting the processing progress

Embodiment Construction

[0026] The polishing head of the present invention includes a head 200 and a shank 100 . The head 200 is used for grinding and polishing the surface of the workpiece, the handle 100 is used for fixing the head 200 at the top, and the end is connected with equipment such as machine tools. The surface polishing of the workpiece is achieved by driving the polishing grinding head to move by the feed of the machine tool or operating the workpiece to be polished to move it.

[0027] Such as figure 1 As shown, in the first embodiment of the present invention, the main body 120 of the handle 100 is a cylindrical metal rod, and an embedded part 110 connected with the main body 120 is provided at the top of the metal rod. The embedded part 110 is cylindrical with a diameter smaller than that of the main body 120 , and has a plurality of concave annular cutouts 111 on the outer surface. A threaded hole is opened at the center of the end of the main body 120 of the handle 100 , and the ...

Abstract

The invention relates to a polishing grinding head which comprises a handle part (100) and a head part (200) connected to the top end of the handle part (100), wherein the head part (200) is made of an elastic deformed material. By adopting the polishing grinding head in the invention, structure and size are designed flexibly, and polishing of different surfaces and free curved surfaces with large curvature change, sharp corner and the like can be realized. The invention has the advantages of reliable performance, stable rigidity, difficulty in breaking, abrasion resistance, convenience for replacement, material saving and environment friendliness.

Description

technical field [0001] The invention relates to the field of machining grinding and polishing, and more specifically relates to a polishing grinding head. Background technique [0002] In real life, many products need to be polished because of surface accuracy requirements or aesthetic considerations. The main method is to move a high-speed rotating grinding head on the surface to be polished to polish the surface. [0003] The existing polishing grinding head is composed of a metal shank and a thin film, and the thin film is located on the top surface of the metal shank. The film is a fiber-reinforced rubber sheet, the outer layer of the film is rubber, and the inside of the rubber is fiber, so that the film can not only have a certain elastic deformation, but also have sufficient toughness and strength. The film is fixed to the metal handle through a certain processing technology so that the inner wall of the film is close to the front end of the metal handle, and the end...
