Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] refer to figure 1 , a magnetorheological airbag flexible polishing tool, the polishing tool includes an airbag 1, the front end of the airbag 1 has a polishing cloth 2 as a working surface, and the front end of the airbag 1 has an interlayer 17; Filled with magnetorheological fluid; the air bag 1 is installed in a cage, the cage is installed on a rotating shaft 3 that can drive the cage to rotate, and the cage includes a polishing head outer cover 4 and a polishing head inner cover 5. The outer cover 4 of the polishing head is connected with the rotating shaft 3 through threads. The polishing cloth 2 and the outer cover 4 of the polishing head are bonded together with resin, and are reinforced with the circlip 6. The inner cover 5 of the polishing head is the polishing cloth 2 for shape determination and adjustment. The shaped parts are connected with the outer...

Abstract

The invention relates to the magnetic rheo-gas cell flexible polishing tool. The said polishing tool comprises a gas cell with a polishing cloth in its front as the work face; an interlayer is in front of the said gas cell, which is filled with the magnetic rheological liquor; the said gas cell is equipped in the retainer; the said retainer is on the drive shaft with one or several pairs of electrical magnets at its front end; the said drive shaft socket joints a sleeving; the said sleeving and the drive shaft gas-tight joint; the said sleeving has outside gas entrance port and the overflow valve; the drive shaft in the sleeving opens the airflow channel that connects the said air cell. The flexibility of the polishing tool head can be controlled online, the contacting area of polishing is big, and the curve face polishing has high efficiency, well adaptation to the curvature change, which can be profiling remembered.

Description

(1) Technical field [0001] The invention relates to a mold surface polishing tool used in cooperation with a machine tool with a power head, in particular for automatic polishing of the mold surface, and is suitable for the occasion of realizing the automation of polishing technology. (2) Background technology [0002] 65% of the mold cavity surface is a curved surface, of which 40% is a free-form surface. The service objects of the mold industry include automobile covering parts, motorcycle covering plastic parts, household appliances such as TV sets, washing machines, air conditioners, etc., and telecommunication products such as mobile phone shells and car lamp shells. Molds in these industries, especially plastic molds, have high requirements on the surface roughness of the cavity, and some need to meet the requirements of mirror surface. Therefore, surface polishing has become an essential process link. According to statistics, polishing accounts for the entire mold man...
