Constant-pressure clamping device for processing of strip-shaped optical glass

Abstract

The invention discloses a constant-pressure clamping device for processing of strip-shaped optical glass. The constant-pressure clamping device comprises a base, mounting seats, a clamping air bag, a liquid storage cylinder, a piston and an electromagnet. In the using process, to-be-processed optical glass is placed between the mounting seats, in the initial state, due to the fluidity of fluid and the elasticity of the clamping air bag, the optical glass can be smoothly placed, and thus the optical glass in different sizes can be conveniently placed between the mounting seats; then the electromagnet is electrified, the electromagnet generates magnetism when electrified, the polarities of the sides, close to each other, of the piston and the electromagnet are the same, the magnetic repulsion force between the electromagnet and the piston drives the piston to descend, thus the fluid is squeezed into the clamping air bag, the clamping air bag is expanded, and thus the optical glass is fixed and clamped; and the optical glass is clamped through the flexible clamping air bag, thus the enough clamping force can be kept, and the circumstance that the optical glass is damaged in the clamping process can also be avoided.

technical field [0001] The invention relates to the technical field of optical glass processing devices, in particular to a constant pressure clamping device for strip optical glass processing. Background technique [0002] Optical glass is a glass material used to manufacture lenses, prisms, mirrors, windows, etc. of optical instruments or mechanical systems, including colorless optical glass, colored optical glass, radiation-resistant optical glass, radiation-resistant glass and optical quartz glass, etc. Optical glass has high transparency, high chemical and physical uniformity, and specific and precise optical constants. It can be divided into silicate, borate, phosphate, fluoride and chalcogenide series. [0003] Optical glass needs to be clamped and fixed during processing.

AI Technical Summary

Problems solved by technology

[0003] Optical glass needs to be clamped and fixed during processing. Rigid clamping is generally used in the prior art. During the clamping process, the splint is in direct rigid contact with the optical glass. If the clamping force is too large, it is easy to distort the optical glass. The glass is broken, but if the clamping force is too small, the clamping will not be firm enough. During the processing, the optical glass is easy to move, resulting in low processing accuracy, or even processing failure, resulting in the scrapping of the optical glass. produce

[0004] When clamping and fixing devices in the prior art are clamping, it is difficult to grasp the clamping force, but in the process of clamping optical glass, there is an optimal clamping force, that is, an optimal clamping pressure , in the prior art, the optical glass cannot be clamped and fixed under the optimal clamping pressure condition
