Abstract

The invention provides a platinum thin-wall round pipe clamp for laser welding. The platinum thin-wall round pipe clamp for laser welding comprises a support and a clamping component rotationally arranged on the support. The clamping component comprises a flange sleeve, a chuck, a displacement adjusting shaft, a fixing cover and a driving mechanism. The chuck and the displacement adjusting shaft are both arranged in the flange sleeve, the rear end of the chuck is connected with the driving mechanism, the front end of the chuck is provided with a tubular joint, the front end of the tubular joint is provided with a plurality of tough clamping pieces, all the clamping pieces are arranged around the tubular joint in the circumferential direction, and the front ends of all the clamping pieces are sleeved with rubber rings. The displacement adjusting shaft is of a hollow tubular structure, and the tubular joint is inserted into the rear end of the displacement adjusting shaft and is in threaded connection with the displacement adjusting shaft. The fixing cover is fixed to the front end of the flange sleeve and provided with a restraining hole and a centering groove extending in the radial direction of the restraining hole and penetrating through the fixing cover. The platinum thin-wall round pipe clamp for laser welding has the beneficial effects that automation of thin-wall round pipe welding is achieved, the laser welding difficulty is reduced, the welding success rate is increased, platinum consumption is reduced, and the cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of metal welding processing, in particular to a platinum thin-walled circular tube clamp for laser welding. Background technique [0002] Before the high-temperature and high-pressure experiment, the experimental sample should be placed in the sample cavity, and then high temperature and high pressure should be applied outside to achieve the effect of simulating the mantle environment. Due to the size limitation of the sample cavity of the rheometer, the outer diameter of the platinum tube to be manufactured is 1-5mm, the length is consistent with the outer diameter, the wall thickness is 0.2mm, and the thickness of the sealed platinum sheet is 0.2mm. If the traditional three-grip chuck is used for clamping, the clamping force will be too large, and the platinum tube is prone to force deformation during the clamping process, and the welding is difficult and the laser will hit the three-grip chuck. If a more...
