Welding robot

Abstract

The welding robot comprises a supporting seat assembly, an annular moving assembly, a first driving assembly, a propelling assembly and a welding assembly, and the supporting seat assembly comprises a supporting seat; the annular moving assembly comprises two arc sections, two arc racks, a first gear, a first sliding seat and a first driving part, the two arc racks are connected with the two arc sections respectively, and the first gear is meshed with the arc racks; the first sliding seat is slidably connected to the circular ring, the fixed end of the first driving part is fixed to the supporting seat, and the output shaft is connected with the first gear; the first driving assembly is connected with the two arc-shaped racks and the supporting seat; the pushing assembly comprises a sliding part, an abutting part and an elastic part, the sliding part is slidably connected to the first sliding base in the radial direction of the circular ring, the abutting part is connected to the sliding part and slidably abuts against the to-be-welded part, and the elastic part is connected to the sliding part and the first sliding base; the welding assembly is connected to the sliding part. The pipeline to be welded can be welded without rotating the pipeline to be welded.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a welding robot. Background technique [0002] In the fields of petrochemical and gas transportation, pipelines are required to transport gas or oil, and the transportation distance is generally long, while the produced pipelines are generally short in length, and multiple sections of pipelines need to be welded together. [0003] Announcement No. CN215616178U discloses a robot welding synchronization device for pipe intersecting line pipe interface, including a base, a pipe A, a pipe B, a machine welding torch and a pipe rotation fixing device, the upper end of the base is fixedly connected with a symmetrical support seat, and the symmetrical support seat A support device is arranged at the upper end, a support plate is arranged on one side of the support base, a fixing device is arranged on the support plate, and the outer side of the fixing device is fixedly connected with the...

Problems solved by technology

[0004] By fixing the welding cavity and rotating the pipe to be welded, the circumferential welding of the pipe to be welded can be realized, but when the pipe is rotated, as the size of the pipe gradually increases, it is necessary to ensure that the two pipes rotate synchronously and the coaxiality becomes more and more coaxial when rotating. Difficulty, lack of means to weld pipes by turning the welding head
