Problems solved by technology

With this method, when spot welding the butt pipe fittings, the concentricity between the two welded pipe fittings is difficult to be guaranteed because the pipe fittings are manually rotated and spot welded.
If the concentricity is required, it will affect the production quality and reduce the welding efficiency to a certain extent

Abstract

The invention relates to a locating device for pipe fitting welding, and belongs to the technical field of rotary locating design of welded pipe fittings. The locating device for pipe fitting welding comprises a workbench and a rotary shaft, wherein a locating support and transmission shaft supporting frames are arranged on the workbench from left to right in sequence, the rotary shaft is horizontally installed on the transmission shaft supporting frames through bearings, a workpiece chuck is installed at the left end of the rotary shaft, and a three-jaw chuck is installed at the right end of the rotary shaft; a workpiece locating mechanism is installed on the locating support, corresponds to the workpiece chuck, and comprises a lead screw and a nut, wherein the lead screw and the nut are matched with each other, the nut is fixed on the locating support, and a workpiece locating block which is matched with the workpiece chuck is installed at the right end of the lead screw through a locating bearing; a motor is arranged corresponding to the rotary shaft. By the adoption of the locating device, when pipe fitting welding with the requirement for high concentricity is conducted, the mode of manual rotating spot welding is cancelled, mechanical alignment is adopted, and concentricity of the two welded pipe fittings is ensured.

Description

technical field [0001] The invention relates to a welding positioning device for pipe fittings, which belongs to the technical field of rotational positioning design of welded pipe fittings. Background technique [0002] At present, the method of semi-automatic welding of pipe fittings is becoming more and more widespread. The general method is to first butt two pipe fittings to be welded, then spot weld, clamp the welded pipe fittings on the rotating parts, and finally weld the pipe fittings with a manual welding gun. Welding, so as to achieve the purpose of semi-automatic welding pipe fittings. With this method, when the butt pipe fittings are spot welded, since the pipe fittings are manually rotated and spot welded, the concentricity between the two welded pipe fittings is difficult to ensure. If the concentricity is required, it will affect the production quality and reduce the welding efficiency to a certain extent. Contents of the invention [0003] According to th...
