Linkage rod type air chuck for laser pipe cutter

Abstract

The invention provides a connecting rod typed gas static-pressing chuck used for a laser pipe cutting machine, belonging to a chuck in the field of mechanical equipment technique. The technical problem to be solved is that the connecting rod typed gas static-pressing chuck used for the laser pipe cutting machine is provided; the technical proposal comprises a horizontal transverse sliding connecting rod mechanism, a horizontal longitudinal clamping mechanism and a chuck seat; the whole chuck takes the longitudinal symmetry axis as a center; the horizontal longitudinal clamping mechanism is symmetrically arranged in longitudinal direction of the chuck; the transverse symmetry axis is taken as a center, the left side of the chuck is provided with the horizontal transverse connecting rod mechanism and the right side thereof is provided with a counterweight. The chuck controls the clamping force by inflating and deflating the cylindrical and by extending and contracting the spring so as to complete a working period of loosening and clamping of the pipes, and is provided with a through hole which allows the pipes to pass by; the clamping block can be adjusted upwards and downwards and the sliding block can be adjusted to the left and the right; the concentricity in a large range can be adjusted without the requirement of replacing the clamping block; the connecting rod typed gas static-pressing chuck is applicable to the clamping requirement of various pipe diameters and can automatically control the loosening and clamping of the chuck.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a novel special chuck for a laser pipe cutting machine. Background technique [0002] Laser pipe cutting machine is a kind of pipe processing equipment, which drives the pipe to rotate through the chuck, and the laser head moves relative to the pipe axis to synthesize the cutting track, and can realize the long pipe processing requirements through segmented serial cutting, in which the pipe rotation index is It is driven by the chuck, so the chuck is one of the most critical components in the laser pipe cutting machine equipment. The laser pipe cutting machine chucks that are usually used before the present invention mainly have the following forms: iron stop type pneumatic chuck, spring type pneumatic chuck, electric chuck and so on. Wherein the prior art closest to the present invention is the self-made iron stop type pneumatic chuck of Changchun Institute of Optics,...

AI Technical Summary

Problems solved by technology

It can be seen from the figure that the structure of the iron-stop pneumatic chuck is relatively simple, and there are many disadvantages. It is greatly affected by the tolerance of the pipe diameter, the centering is not accurate, there is a setting error, and the adaptability to the pipe diameter is small. Multiple processing needs to be constantly replaced to adapt to different clamping blocks. Pipe diameter requirements, etc.
