A pipe fitting welding device

Abstract

The invention discloses a pipe fitting welding device. The pipe fitting welding device comprises a frame body composed of a cross rod and support legs fixed at the bottoms of the left side and the right side of the cross rod; a sliding groove is formed in the bottom end surface of the cross rod and is provided with a first spiral rod extending leftwards and rightwards; a sliding block is connected to the first spiral rod is in a spiral matched mode; a pipe fitting welding device body is arranged at the bottom of the sliding block; a sinking groove is formed in the front end of the pipe fitting welding device body; a first sliding cavity is correspondingly arranged at the position, at the upper side and the lower side of the sinking groove, in the pipe fitting welding device body; second sliding cavities extending rightwards are formed in the sides, away from the sinking groove, of the first sliding cavity and are connected; second spiral rods extending leftwards and rightwards are arranged in the second sliding cavities; push blocks are connected to the second spiral rods in the spiral matched mode; a limiting block is arranged on the side, close to the sinking groove, of the inner wall of the right side of the first sliding cavity; and a longitudinal sliding block is connected to the first sliding cavity in a sliding and matched mode. The pipe fitting welding device is simple in structure, convenient to install and disassemble, high in welding efficiency and capable of meeting the welding work of pipe fittings with different diameters.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a pipe fitting welding device. Background technique [0002] When welding two pipe fittings, workers need to hold electric welding machines to weld them. In order to prevent the interface from touching the ground and polluting, it is necessary to wait for one side of the interface to cool down and then flip the pipe fittings to weld on the other side. This welding method is inefficient. It is time-consuming and labor-intensive, and the existing special welding machines for pipe fittings are generally for large pipe fittings, and some welding machines for small pipe fittings have only one welding gun head, and the welding efficiency is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipe fitting welding device, which can solve the above-mentioned problems in the prior art. [0004] The present invention i...
