Tool for clamping minor-caliber optical mirror slip

Abstract

The invention relates to a tool for clamping a minor-caliber optical mirror slip, which comprises a sleeve with a stepped cavity, a piston, a first sealing ring, a second sealing ring, an operating handle and a screw cap, wherein a cavity on the lower part of the sleeve is the biggest, a cavity on the upper part is the smallest, the cavity wall of a middle cavity is provided with left-hand threads, a port end face on the bottom of the sleeve is provided with an annular groove, and the first sealing ring is embedded in the groove; a body of the piston is a stepped shaft with a thin end and a thick end, the thick end is provided with two continuous annular prominences along the circumferential direction of the shaft, the match relation between the diameter of the end-piece annular prominenceand the diameter of the cavity on the lower part of the sleeve is sliding fit, the periphery of the outer wall of the part is provided with a groove which is embedded with the second sealing ring, and the outer wall of the second annular prominence is provided with threads; and the thin end of the body penetrates through the cavities of the sleeve, is provided with external threads and is fixed together with the operating handle through the screw cap. The tool has the advantages of compact structure, convenient operation and low cost.

Description

technical field [0001] The invention relates to a clamping tool, in particular to a clamping tool used for clamping small-diameter optical lenses. Background technique [0002] When installing a small-diameter optical lens on an optical adjustment frame or a lens fixing device, the traditional method is to use tweezers to clamp the lens periphery, or the operator wears a rubber finger cot to clamp the lens periphery with his fingers, and puts the lens in the corresponding position. Both approaches have flaws. When clamping the lens with tweezers, ordinary tweezers are composed of two elastic steel plates. With the help of the operator's fingers, the two steel plates of the tweezers clamp the lens. Once the operator's fingers become fatigued, the clamping force is relaxed, and the lens is very fast. It is easy to fall off; or the lens may be scratched. In the way that the operator wears rubber finger cots, the operator must wear the finger cots every time the lens is instal...

Problems solved by technology

When clamping the lens with tweezers, ordinary tweezers are composed of two elastic steel plates. With the help of the operator's fingers, the two steel plates of the tweezers clamp the lens. Once the operator's fingers become fatigued, the clamping force is relaxed, and the lens is very fast. Easy to fall off; or may scratch the lens

In the way that the operator wears rubber finger cots, the operator must wear finger cots every time the lens is installed, which will reduce production efficiency
