Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] combine Figure 1 to Figure 4 , the welding guide rail 1 of the present invention is fixed on the pipeline to be welded by the guide rail fixing device 3, the assembled welding robot is assembled on the pipeline to be welded, and the welding robot realizes the welding torch through the radial lifting mechanism and the swing mechanism. For the alignment of the welding seam, the supply of welding wire during the welding process is realized through the wire feeding mechanism, and the 360-degree circumferential movement of the welding mechanism is completed through the walking mechanism to complete the pipeline welding work. The specific process is as follows:
[0019] Motor Ⅰ6 drives gear Ⅰ7 to rotate, and then drives gear Ⅱ8 to rotate. Gear Ⅱ8 is connected to ball screw Ⅰ10 to transmit power, and drives screw nut Ⅰ9 on ball screw...

The invention provides a butt pipe type welding robot which comprises a welding guide rail which is formed by two symmetric semi-rail structures, a walking mechanism, a radial lifting mechanism, a swinging mechanism and a wire feeding mechanism, wherein the welding guide rail is fixed to a pipeline to be welded through a fixing device; the wire feeding mechanism has the function of uniformly sending welding wires to a welding part, so that filling of a solder is met, and the effect of uniformly filling is reached; the walking mechanism is mainly used for dragging a welding tractor to move surrounding the pipe wall along the welding guide rail; the welding part is composed of the swinging mechanism and the radial lifting mechanism; the swinging mechanism has the main function of regulating a welding gun to be at the position in the direction of a busbar of the welded pipeline to align to a weld groove before welding starts and carrying out micro swinging movement in the welding process; and the radial lifting mechanism has the main function of regulating the height between the welding gun and the weld groove so as to meet the requirement of solder filling height. The butt pipe type welding robot has the characteristics of small size of a whole machine, light weight, convenience in installation and the like.
Description
technical field [0001] The invention relates to a welding robot, in particular to a butt pipe type welding robot, and relates to the field of land pipeline welding. Background technique [0002] At present, pipelines often need to be welded in the laying of pipelines, and butt joint welding robots play an important role in the welding of pipelines. Because most of the pipeline welding robots are imported, the price is relatively expensive, and although the traditional manual arc welding is flexible in operation, it has high technical requirements for welders and high labor intensity, the welding environment is harsh, and the welding quality is rough and poor. The precision is low, and the quality and life of the weld cannot be effectively guaranteed, so the use of automated welding robots is of great significance to welding production. [0003] With the continuous rapid development and improvement of technology in the global industrial manufacturing field, the users of pipe...
