Clamping and welding robot for pipeline production

Abstract

The invention discloses a clamping and welding robot for pipeline production, and belongs to the technical field of welding. The robot comprises a welding gun, a bottom plate and plastic pipes; two first supporting blocks are symmetrically fixed to the upper surface of the bottom plate, a controller is arranged on one side of one first supporting block, semicircular grooves are formed in the upper surfaces of the first supporting blocks, the plastic pipes are located in the semicircular grooves, and a conveying assembly is arranged on one side of each first supporting block; two clamping assemblies, two induction assemblies, two supporting assemblies and a welding assembly are arranged on the bottom plate, wherein the two clamping assemblies, the two induction assemblies and the two supporting assemblies are symmetrically arranged; the conveying assemblies comprise second mounting plates, sliding blocks, first motors, sliding rods, screw rods, second motors, round rods and conveying rollers; and the clamping assemblies comprise U-shaped plates, first cylinders, second cylinders, third motors, first gears, extrusion columns and second gears. According to the robot, through the design of the conveying assemblies and the clamping assemblies, when the robot is used for welding, the labor amount can be reduced, and meanwhile, the welding effect can be improved.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a clamping and welding robot for pipeline production. Background technique [0002] Plastic welding refers to the connection method that melts the contact surfaces of two plastic parts at the same time by heating, so that they are combined into a whole. It is only suitable for thermoplastic connections. Welding rods can be used or not. When using welding rods, It is necessary to make the seam of the specified shape (such as U-shape, X-shape, etc.) on the end face of the welded end, and the welding rod molten body drips into the seam, and the two welded parts are connected into one body. When the welding rod is not used, the welding surface is heated and melted , and then apply vertical pressure to the surface to be welded until it is tightly fused together. At present, most of the welding between the nozzles of plastic pipes adopts the method of hot-melt butt joint o...

[0002] Plastic welding refers to the connection method that melts the contact surfaces of two plastic parts at the same time by heating, so that they are combined into a whole. It is only suitable for thermoplastic connections. Welding rods can be used or not. When using welding rods, It is necessary to make the seam of the specified shape (such as U-shape, X-shape, etc.) on the end face of the welded end, and the welding rod molten body drips into the seam, and the two welded parts are connected into one body. When the welding rod is not used, the welding surface is heated and melted , and then apply vertical pressure to the surface to be welded until it is tightly fused together. At present, most of the welding between the nozzles of plastic pipes adopts the method of hot-melt butt joint of plastic pipes. The welding interface of two plastic pipes is heated with a heating plate until sticky. After the fluid state, remove the heating plate, and then artificially apply opposite pressure to the two plastic pipes, and cool and solidify under this pressure state to form a firm connection. In the process, manpower is required to carry the plastic pipes, which improves the welder's work efficiency. At the same time, it is difficult to ensure that the axes of the two plastic pipes coincide during manual welding, and it is easy to bend the welded plastic pipes
