Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] What the present invention discloses is a kind of air bag polishing head that can self-adjust air pressure, as Figure 1 to Figure 5 Shown is a preferred embodiment of the present invention. The airbag polishing head includes an airbag disc 1 , a polishing airbag 2 , an air pressure self-regulating module 3 and an intake valve 4 . in:

[0029] The airbag disc 1 is used for fixed installation of the polishing airbag 2, and various structures can be adopted for its fixed installation. In this embodiment, an annular groove 11 is provided below the airbag disc 1, and an annular boss 26 is arranged on the outer periphery of the non-processing side of the polished airbag 2. When installing, the annular boss 26 is stuck in the annular groove 11, and then the A compression washer 5 is sleeved on the polishing airbag 2 and located be...

Abstract

The invention discloses an air bag polishing head capable of self-adjusting air pressure. The air bag polishing head capable of self-adjusting the air pressure comprises an air bag tray, a polishing air bag, an air pressure self-adjusting module and an air inlet valve, wherein the processing side of the polishing air bag is of a sphere crown shape, and the other side of the polishing air bag is fixedly mounted on the air bag tray; a polishing chamber is formed in the polishing air bag; the outer surface of the processing side of the polishing air bag is opposite to the polishing chamber area,or partial or the whole area is opposite to a polishing working part; the air pressure self-adjusting module is used for automatically adjusting the air pressure in the polishing chamber; and the airinlet valve supplies support to inflate air into the polishing air bag. With the adoption of the air bag polishing head capable of self-adjusting the air pressure, the purposes of automatically buffering and balancing the air pressure in the polishing chamber of the polishing air bag, avoiding rigid contact, and realizing ultra-accurate polishing with high buffering flexibility can be achieved.

Description

technical field [0001] The invention relates to an airbag polishing head capable of self-adjusting air pressure, which belongs to polishing equipment, in particular to a polishing equipment for airbag polishing. Background technique [0002] At present, airbag polishing is an important means for precision / ultra-precision finishing of optical components, especially large-scale optical aspheric components. Balloon polishing fills the spherical airbag with a certain pressure of gas, and under the designed path, speed and pressure, uses the polishing pad pasted on the head of the spherical airbag to realize the polishing operation of the workpiece. Because the airbag polishing head is tightened under the action of internal air pressure, when the airbag polishing head is pressed against the workpiece, the airbag polishing head and the workpiece are in "rigid" contact, which will have a certain impact on the polishing quality. [0003] The authorized announcement number is CN1028...
