a welding device

Abstract

A welding device comprises a welding rack and a welding box fixedly mounted at the upper end of the welding rack, as well as a spot welder, wherein rollers are arranged at the bottom of the welding rack; a braking vane is arranged on the right side surface, above each roller, of the welding rack; an accommodating cavity is formed in the welding box; lifting grooves stretching up and down are arranged in the front inner wall and the rear inner wall of the accommodating cavity; sliding arms matched with the lifting grooves are symmetrically arranged on the spot welder in tandem; each sliding arm is provided with an oblique groove; a welding head is mounted at the lower end of the spot welder; indentation grooves of which end openings face downwards are formed in the spot welder in bilateral symmetry; a pressing block capable of sliding up and down is arranged in each indentation groove; a tension spring is fixedly mounted at the upper end of each pressing block; and the upper ends of the tension spring are fixedly connected with the top walls of the corresponding indentation grooves.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding device. Background technique [0002] With the continuous maturity of welding technology, the actual application of welding plates is becoming more and more extensive. In some large-scale welding fields, due to the mass production of welding plates, some more welding plates have poor welding quality due to special reasons. The occurrence of breakage, adhesion and other phenomena requires secondary repair welding. The existing repair welding of welded plates is generally done by manual spot welding. Due to the instability of manual operation, it is difficult to ensure the welding quality, and in the welding process The welded plate needs to be fixed. When a welded plate is repaired after welding, it needs to be removed, and then the next welded plate is fixed first and then welded.

[0002] With the continuous maturity of welding technology, the actual application of welding plates is becoming more and more extensive. In some large-scale welding fields, due to the mass production of welding plates, some more welding plates have poor welding quality due to special reasons. The occurrence of breakage, adhesion and other phenomena requires secondary repair welding. The existing repair welding of welded plates is generally done by manual spot welding. Due to the instability of manual operation, it is difficult to ensure the welding quality, and in the welding process The welded plate needs to be fixed. When a welded plate is repaired after welding, it needs to be removed, and then the next welded plate is fixed first and then welded. The welding process is more complicated and difficult, which greatly reduces the welding efficiency. At the same time, through Manual operation of the spot welding machine has certain safety hazards
