Clamping device for thin-wall cylindrical glass piece

Abstract

The invention provides a clamping device for a thin-wall cylindrical glass piece. The clamping device comprises a stainless steel sleeve, wherein the inner wall of the sleeve is provided with an inferior-arc-shaped groove extending along a spiral line, a hose with the outer diameter equal to the diameter of the inferior arc is contained in the groove, one end of the hose is blocked, the other end of the hose is connected with an inflating and deflating device which can inflate and deflate the hose, and the thin-wall cylindrical glass piece is placed in the center of the spiral surrounding hose. The thin-wall cylindrical glass piece is placed in the center of the spiral surrounding hose, the inflating and deflating device inflates the hose, and the hose expands with air inflation and makes contact with the outer surface of the thin-wall cylindrical glass piece till the thin-wall cylindrical glass piece is clamped. The hose clamps the thin-wall cylindrical glass piece through inflation and makes elastic contact with the thin-wall cylindrical glass piece, clamping force is convenient to control, and therefore the thin-wall cylindrical glass piece can be firmly clamped and the clamping effect is good.

Description

technical field [0001] The invention relates to a clamping device for a thin-wall cylindrical glass piece. Background technique [0002] The clamping of thin-walled cylindrical glass parts (such as glass cups) has always been a difficult problem. Due to the thin wall and smooth surface, the current mechanical clamps directly contact the thin-walled cylindrical glass parts hard, which is likely to cause the following two problems: [0003] 1. Since the wall of the thin-walled cylindrical glass is thin and fragile, it is easy to be crushed; [0004] 2. Since the surface of the thin-walled cylindrical glass is smooth, it is easy to slip off and the clamping is not reliable. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a clamping device for a thin-walled cylindrical glass piece, which has a good clamping effect. [0006] In order to solve the problems of the technologies described above, the technical soluti...
