Electric-driving double-acting full-stroke chuck

Abstract

The invention relates to the technical field of pipe fitting clamps, in particular to an electric-driving double-acting full-stroke chuck. The electric-driving double-acting full-stroke chuck comprises a chuck body, at least one pair of clamping jaws and clamping jaw driving mechanisms, and the clamping jaw driving mechanisms are used for controlling all the pairs of clamping jaws to move in the same direction or oppositely and mounted in the chuck body. Each pair of clamping jaws corresponds to one corresponding group of clamping jaw driving mechanism. When the clamping jaws are arranged in two or more pairs, the motion of all the groups of clamping jaw driving mechanisms is relatively independent and does not interfere with one another. Two pairs of clamping jaws can be adopted in the electric-driving double-acting full-stroke chuck, and the four clamping jaws achieve a pairwise self-centering function; the motion of the two pairs of clamping jaws is staggered and does not interfere with each other, that is, the motion of the clamping jaws is asynchronous. The electric-driving double-acting full-stroke chuck is especially suitable for clamping workpieces in a non-centrosymmetry shape, such as workpieces with rectangular, triangular and oval sections and the like. If the electric-driving double-acting full-stroke chuck needs to be moved, only the number of motors and corresponding gears needs to be increased.

Description

technical field [0001] The invention relates to the technical field of pipe fixtures, in particular to an electric-driven double-action full-stroke chuck. Background technique [0002] The principle of pipe cutting machine and pipe welding machine is through the mutual cooperation of computer and hydraulic pressure, and the electric system controls the oil circuit movement direction of the hydraulic system, and pushes the carriage to make linear reciprocating motion. The microcomputer will walk according to the user-edited cutting route. During the reciprocating movement, the signal detected by the carriage limit is used as a basis to control and change the movement of its oil circuit, so as to achieve the expected cutting route. [0003] Pipe cutting machines, pipe welding machines, etc. need to fix the pipe fittings before work. Generally, chucks are used to fix them. The jaws on the existing chucks all move synchronously, that is, they move toward each other or at opposit...

Problems solved by technology

[0003] Pipe cutting machines, pipe welding machines, etc. need to fix the pipe fittings before work. Generally, chucks are used to fix them. The jaws on the existing chucks all move synchronously, that is, they move toward each other or at opposite speeds at the same speed, and can only be aligned. Polygonal or centrally symmetrical shapes are fixed, and the scope of application is small; and the stroke of the jaws is relatively short compared with the chuck, and the utilization rate is not high
