a welding device

Abstract

The invention discloses a welding device. The welding device comprises a frame composed of a cross bar and supporting legs fixed to the bottoms of the left and right sides of the cross bar. A sliding groove is formed in the bottom end face of the cross bar. A first screw rod extending left and right is arranged in the sliding groove. A sliding block is connected into the first screw rod in a screw-thread fit mode. The bottom of the sliding block is provided with a welding device body. A countersunk groove is formed in the front end of the welding device body. A first sliding cavity is correspondingly formed in the part, on the upper and lower sides of the countersunk groove, of the welding device body. The side, far from the countersunk groove, of the first sliding cavity is provided with a second sliding cavity extending rightwards. The first sliding cavity communicates with the second sliding cavity. A second screw rod extending left and right is arranged in the second sliding cavity. A push block is connected to the second screw rod in a screw-thread fit mode. A limiting block is arranged on the side, close to the countersunk groove, of the inner wall of the right side of the first sliding cavity. A longitudinal sliding block is connected into the first sliding cavity in a sliding fit mode. The welding device is simple in structure, convenient to mount and demount, high in welding efficiency and capable of meeting the requirements for welding of pipe fittings with different diameters.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a 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 welding device, which can solve the above-mentioned problems in the prior art. [0004] The present invention is achieved through the foll...
