Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical processing technology, and in particular to an airbag head that facilitates the replacement of polishing pads. Background Technology
[0002] In the field of optical processing, airbag polishing technology is widely used for polishing complex optical components such as aspherical and freeform surfaces due to its flexible contact and high-precision processing capabilities. Traditional airbag heads typically use adhesive bonding to fix the polishing pad, which has the following problems: First, each time the polishing pad is replaced, bonding and curing are required, which is time-consuming and affects production efficiency; second, the bonding process requires precise control of the amount and uniformity of adhesive, which is difficult to operate, and the use of adhesive materials (such as glue) increases costs. Furthermore, the cured polishing pad is difficult to reuse, and chemical adhesives may cause environmental pollution. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an airbag head that facilitates the replacement of polishing pads.
[0004] The purpose of this utility model is achieved through the following technical solution: an airbag head that facilitates the replacement of polishing pads, including a ball head base, a ball head body is provided inside the upper end of the ball head base, an mounting plate is provided on the outer side of the ball head base, a plurality of threaded holes a are provided on the mounting plate, a ball head cover is threadedly installed on the outer side of the ball head base, and a through hole is provided at the upper end of the ball head cover.
[0005] Preferably, a mounting plate b is provided on the outer side of the lower end of the ball head cover, and the mounting plate b has a threaded hole b corresponding to the threaded hole a.
[0006] The present invention has the following advantages: By placing the polishing pad between the ball head body and the ball head cover, and then fixing the ball head cover to the ball head base with bolts, the polishing pad can be quickly installed and removed without the need for glue, which improves production efficiency, reduces production costs, reduces environmental pollution, and the polishing pad can be reused.
