Suspended type pipe-jointing welding robot

Abstract

The invention provides a hanging-style pipe connecting welding robot composed of an electrical sliding loop part, a rotary mechanism, a stretching mechanism, a lifting mechanism, a sewing mechanism and a manually lifting adjusting mechanism. The rotary mechanism consists of a fixed part and a rotary part. The fixed part of the rotary mechanism is fixed on the end of the horizontal arm of the cross arm as a seat of the hanging-style robot, and the stretching mechanism is arranged on the rotary part of the rotary mechanism. The lifting mechanism is arranged on the stretching mechanism, and the lifting adjusting mechanism is arranged on the lifting mechanism, the sewing mechanism is arranged on the manually lifting adjusting mechanism. The electrical sliding loop part is arranged on the rotary mechanism. By adjusting the relative position between the welding robot and the connecting pipe and adjusting the manually lifting adjusting mechanism to proper welding position, the hanging-style pipe connecting welding robot can realize linkage at four degrees of freedom, and can perform automatic welding for different shape of pipes with the advantages of good welding quality, high efficiency and reduced labor intensity of workers.

Description

(1) Technical field [0001] The invention relates to an industrial welding robot, in particular to a joint intersecting line welding robot used for cylinders, ellipsoidal caps, spherical caps and cones. (2) Background technology [0002] At present, pipe welding robots mostly use three-jaw or four-jaw chucks for clamping. When clamping on the welded pipe, the heat generated by welding is easily transmitted to the chuck, causing it to be stuck due to thermal deformation, making it difficult to disassemble the chuck. ; In the welding with tightly distributed nozzles, the welding work space of the clamp-type welding robot is severely limited. At the same time, due to the installation method of the clamp-type welding robot, the operating space left for the operator is very small, which is not conducive to the operator's safety.

Problems solved by technology

[0002] At present, the connection welding robot mostly adopts three-jaw or four-jaw chucks for clamping, and the clamping is carried out on the welded connection pipe, which is very easily transmitted to the chuck due to heat generated by welding, causing it to be stuck due to thermal deformation, making it difficult to disassemble the chuck ; In the welding with closely distributed nozzles, the welding operation space of the clamp-type welding robot is severely limited. At the same time, due to the installation method of the clamp-type welding robot, the operating space left for the operator is very small, which is not conducive to the operator's safety. Real-time observation and operation; It is difficult to realize the chucking of the pipe welding robot using the three-jaw or four-jaw chuck for the welding of the opposite pipe, oval pipe, tapered pipe and other irregular pipes, so that it is impossible to realize the chucking for welding; urgently needed in practice A robot that is easy for workers to observe and operate, can avoid the chuck from being stuck due to welding heat, and can adapt to welding of different shapes.
