Fixing device for welding

Abstract

The invention discloses a fixing device for welding. The fixing device comprises a fixing rod and a fixing ring which is integrated with the fixing rod to form a whole, wherein the fixing ring is used for fixing a pipe fitting; the right end of the fixing rod is fixedly arranged at the top of a lifting rod driven by a motor; a base is arranged at the bottom of the lifting rod; an iron block, a sliding cavity and a storage cavity are arranged in the fixing rod, and a thread loop is arranged at the outer part of the iron block in a sleeving manner; a channel connected with outside and the sliding cavity, and a channel connected with the sliding cavity and the storage cavity are formed in the fixing rod; a controller is arranged on a lateral side of the fixing rod; a magnet is arranged in the sliding cavity, located at one end of the iron block; a sliding plate is fixed to one end surface of the magnet; and an internal channel is formed in the middle of the sliding plate and the magnet. Through the adoption of the fixing device disclosed by the invention, the pipe fitting can be effectively fixed, so that two pipe fittings can be conveniently welded; in addition, electromagnetism is utilized for control, so that the fixing device has controllability; and besides, the degree of tightness for fixing the pipe fitting can be controlled according to the magnitude of electric current, so that different demands can be met.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welding fixing device. Background technique [0002] When welding two pipe fittings, it is necessary to align and fit the nozzles of the two pipe fittings. In traditional welding, the welder holds the welding equipment with one hand, and clamps one of the pipe fittings with a clamp with the other hand to make it fit The other pipe fits together, and it is very laborious to hold the fixture for a long time, and the shaking of the hand will inevitably cause deviation during the welding process, which will affect the welding quality. Contents of the invention [0003] The object of the present invention is to provide a welding fixture to solve the problems raised in the background art above. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A welding fixing device, comprising a fixing rod and a fixing ring integral with the ...
