Description

Technical Field

[0001] This utility model mainly relates to the field of electric welding machines, specifically to an electric welding machine with automatic feeding capability. Background Technology

[0002] An electric welding machine uses the high-temperature electric arc generated when the positive and negative electrodes are short-circuited momentarily to melt the solder on the welding rod and the material being welded, thus joining the objects together. Its structure is very simple; it is essentially a high-power transformer.

[0003] Electric welding machines are generally classified into two types according to the type of output power: AC power and DC power. They utilize the principle of inductance, where the inductance generates a huge voltage change when the circuit is switched on and off. The high-voltage arc generated when the positive and negative poles are momentarily short-circuited melts the welding material on the welding rod, achieving atomic bonding between the electrodes.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] However, when welding fan-shaped plates with an electric welding machine, if there is a large gap between the two arc-shaped plates, it is easy for the welding machine to cause incomplete welding or an inability to firmly connect the two plates during the welding process, which will affect the normal use of the plates after welding.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0034] The side support structure 3 includes a sliding ring 301, the number of which is set to two, a push spring 304 is provided between the two sliding rings 301, a rotating block 302 is rotatably connected to the top of the sliding ring 301, a planar spiral spring is provided between the rotating block 302 and the sliding ring 301, and a positioning groove 303 is provided on one side of the rotating block 302.

[0035] Two curved plates are placed on top of the mounting structure 1 and the plates are attracted by the bottom support structure 2. Then, the sliding ring 301 is released and the spring 304 is pushed to push the sliding ring 301 to slide on top of the mounting structure 1. The positioning groove 303 is attached to the outer wall of the plate and pushes the connection position of the two plates to align. Then, the diameter of the two plates is electric welded by the welding structure 4.

[0036] Furthermore, the mounting structure 1 includes a base plate 101, a limiting hole 102 is formed inside the base plate 101, a fitting groove 103 is formed inside the base plate 101, and a servo motor 104 is arranged in the middle of the base plate 101.

[0037] Furthermore, the bottom support structure 2 includes a sliding plate 201, which is slidably connected to the top of the base plate 101. A sliding hole 202 is provided in the middle of the sliding plate 201, and a lifting shaft 203 is slidably connected inside the sliding hole 202.

Then, without releasing the plate, push the plate to move through the side support structure 3, push the spring 304 to push the rotating block 302 to slide on the inner wall of the fitting groove 103, and push the spring 304 on one side of the positioning groove 303 at the top of the rotating block 302 to fit with the outer wall of the plate, so that the plate drives the sliding plate 201 to slide on the inner wall of the base plate 101.

The mounting frame 401 drives the bonding strip 402 to slide on the outer wall of the base plate 101 through the transmission screw 405, so that the moving shell 406 is aligned with the connection position between the two plates. Then the motor drives the transmission screw 405 to rotate, and the transmission screw 405 drives the moving shell 406 to move, so that the moving shell 406 moves along the connection position, so that the welding machine body 411 can perform welding on the connection position between the two arc-shaped plates.
