The invention provides a pipe flange welding locating device which comprises a fixed seat, a first locating mechanism, a push-pull block and a push-pull driving mechanism. The first locating mechanism is installed on the fixed seat, the push-pull block is arranged on the fixed seat and abuts against the first locating mechanism, and the push-pull driving mechanism is matched with the push-pull block. The fixed seat is provided with a base and a central shaft extending in the axial direction from the base to pipes. The first locating mechanism sleeves the central shaft. The first locating mechanism comprises a plurality of first floating wedge blocks arranged between the base and the push-pull block and first elastic elements sleeving the first floating wedge blocks in the circumferential direction of the central shaft. Matched slopes are arranged between the first floating wedge blocks and the push-pull block. According to the first locating mechanism, when the push-pull driving mechanism pushes and pulls the push-pull block in the axial direction, the first floating wedge blocks can move inwards or outwards in the radial direction of the central shaft under the action of the push-pull block and the action of the first elastic elements.
Description
technical field [0001] The invention relates to the technical field of pipe fitting welding, in particular to a pipe fitting flange welding positioning device. Background technique [0002] In conventional pipeline welding, when connecting pipe fittings and flanges, it is necessary to spot weld the flanges at both ends of the pipe fittings with the pipe fittings first, and then install them on the clamping and rotating device for circular seam welding. In spot welding, the taper pipe and the flange are usually butt-welded manually and then spot welded. However, it is difficult to ensure the coaxiality between the flanges at both ends and the taper pipe by manual docking, resulting in poor welding quality and low welding efficiency. [0003] Therefore, it is necessary to provide a flange welding positioning device for pipe fittings to overcome the above problems. Contents of the invention [0004] The object of the present invention is to provide a pipe fitting flange weld...
