Positioning device beneficial for pipeline welding

Abstract

The invention discloses a positioning device beneficial for pipeline welding in the technical field of welding. The positioning device comprises a bottom plate. A first motor is installed at the center of the top of the bottom plate. The power output end of the top of the first motor is connected with a main bevel gear through a speed reducer. The top of the bottom plate is provided with a rotating rod. The circumferential outer side of the rotating rod is rotationally connected with two symmetrical inner supporting rods through bearings. The bottoms of the inner supporting rods are fixedly connected to the top of the bottom plate. The middle of the circumferential outer side of the rotating rod is fixedly connected with an auxiliary bevel gear. The auxiliary bevel gear meshes with the main bevel gear. The two sides of the rotating rod are fixedly connected with two symmetrical driving wheels. The top of the bottom plate is fixedly connected with two outer rods in left-right symmetry.The sides, close to each other, of the two outer rods are each rotationally connected with a support through a bearing. The circumferential outer side wall of the support is fixedly connected with a driven wheel. The driven wheel is connected with the driving wheels through a belt. Thus, the invention provides the positioning device for pipeline welding and beneficial for rotating pipelines.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a positioning device for pipeline welding. Background technique [0002] Welding, also known as welding and welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. Pipelines are connected by pipes, pipe connectors and valves. A device for transporting gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high pressure of the pipeline to the low pressure. It can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly used in water supply, drainage, heat supply, gas supply, long-distance oil and natural gas transportation, agricultural irrigation, hydraulic engineering and various industrial installations. The existing pipelines can...

Problems solved by technology

[0005] The purpose of the present invention is to provide a positioning device for pipe welding to solve the problem that although the pipe is not easy to move and easy to weld, the device cannot rotate the pipe when welding the pipe, and manual rotation is required. Not only wastes time, but also easily causes uneven welding and poor welding effect; the pipe cannot be fixed according to the diameter of the pipe, and it cannot be widely used
