a welding device

Abstract

The invention relates to a novel welding device, which comprises a welding frame, a welding box and a point welding machine, wherein the welding box is fixedly arranged at the upper end of the welding frame; rolling wheels are arranged at the bottom of the welding frame; a brake plate is arranged at the right side surface of the welding frame arranged above the rolling wheels; an accommodating cavity is formed in the welding box; ascending and descending grooves extending in the vertical direction are formed in the front and back inner walls of the accommodating cavity; sliding arms matched with the ascending and descending grooves are symmetrically arranged at the front part and the back part of the point welding machine; each sliding arm is provided with an inclined angle groove; the lower end of the point welding machine is provided with a welding head; retraction grooves with downward end openings are symmetrically formed in the point welding machine at the left side and the right side; a press block is arranged in each retraction groove in a way capable of vertically sliding; the upper end of each press block is fixedly provided with a tension spring; and the upper end of each tension spring is fixedly connected with the top wall of the corresponding retraction groove.

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. The welding process is more complicated and difficult, which greatly reduces the welding ...

[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
