Abstract

The invention relates to the technical field of hoisting clamps, and discloses a clamp for tubular parts. The clamp for the tubular parts comprises a first rotation shaft, a limiting circular ring, and a support rod. The first rotation shaft is provided with an arc convex part. The support rod slidably passes through the side wall of the limiting circular ring. One end of the support rod is slidably connected with the surface of the arc convex part. One end of the support rod is fixedly connected with a support plate. The outer surface of the support plate is provided with a first opening. Aninternal gear is rotatably connected in the support plate. The outer surface of the internal gear contacts with the first opening. The internal gear is internally meshed with a first external gear. The first external gear is coaxially connected with a second external gear. The second external gear is meshed with a rack. Two ends of the rack are hinged with a slide bar. Along with the axial movement of the tubular part, the internal gear drives the slide bar to be moved, a friction force between the inner wall of the tubular part and the clamp is increased, and the tubular part is prevented from being continuously moved. The clamp is capable of clamping and hoisting the tubular parts, and has the advantage of controlling the axial movement of the tubular parts in time.

Description

technical field [0001] The invention relates to the technical field of hoisting fixtures, in particular to a clamping device. Background technique [0002] In the process of processing tubular parts, it is usually necessary to use clamps to fix them before they can be lifted. However, in the prior art, the clamping and fixing of clamps and tubular parts is not reliable, and the tubular parts may still occur along the axis. Moving, even the danger of falling will occur in serious cases, and it will also affect the accuracy of the positioning of tubular parts, which is not conducive to production. [0003] Therefore, how to improve the problem of axial movement of tubular parts during clamping and lifting is an urgent problem to be solved now. Contents of the invention [0004] The present invention intends to provide a clamp for tubular parts to overcome the problem of axial movement of the tubular parts in the prior art during clamping and lifting. [0005] In order to a...
