[0017] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below.

[0018] The utility model provides a welding auxiliary fixture, which is composed of a basic frame 1 and an iron magnet 3. The basic frame 1 is welded by four iron bars 2 with different lengths, which are 10mm wide and 3mm thick. The lengths are 1000mm, 150mm, 70mm and 45mm respectively.

[0019] First, take the center of the 150mm iron bar, and weld the 45mm iron bar to the center to form a T shape.

[0020] Then take the center of the 1000mm iron bar and place the 70mm iron bar facing the center to form a T shape.

[0021] Finally, weld the remaining end of a T-shaped 45mm iron bar and the remaining end of another 70mm iron bar to form a T shape.

[0022] The magnet is a cylindrical shape punched out of iron sheet according to the round size of the magnet. Glue is applied to the surface of the magnet and placed into the cylindrical iron sheet until the magnet and the iron sheet are firmly bonded.

[0023] Five strong magnets are welded by argon arc welding on the T-shaped surfaces of 150mm and 45mm at the bottom of the fixture, and the fixture is completed.

[0024] Instructions for use:

[0025] Step 1: When using this fixture, place the longest end of the fixture directly along the direction of the weld.

[0026] Step 2: Place the magnet at the lower end of the weld.

[0027] Step 3: CO 2 The welding gun is placed on the longest end of the fixture, which plays a good auxiliary role. The direction of the fixture guides the direction of the weld to start welding. The length of the weld after welding is also increased, and the straightness after welding is also improved. In addition, when welding the elevation weld, the fixture is directly adsorbed under the weld, and the CO2 welding gun is placed on it, which plays a good role in supporting the gun. The length of the weld is also increased, the weld is also beautiful, and the difficulty and strength of welding are reduced a lot.

[0028] Put the fixture on the weld to serve as a guide, making it easier to find the weld and less likely to weld off-center.

[0029] This fixture plays a supporting role for the CO2 welding gun, reduces labor intensity, and also reduces the difficulty of welding in overhead and horizontal welding positions.

[0030] The weld length and straightness after welding are also increased, which can well meet the quality inspection department's requirements for the welds inside the body side panels.

[0031] When using this fixture to weld the overhead and horizontal positions of the car body, this fixture is directly adsorbed under the weld and the CO2 welding gun is placed on it, which plays a good role in supporting the gun. The length of the weld is also increased, the height difference and width difference of the weld are greatly reduced, and the amount of post-weld grinding of the weld is reduced, which greatly improves the overall appearance weld quality of the car body and reduces the welding difficulty and strength a lot.

[0032] This welding tool is used in the welding of 8X8 wheeled vehicles. The increased speed, reduced rework rate and lower labor costs have saved the company tens of thousands of yuan in value.

[0033] After welders use this fixture, first of all, the difficulty of welding is reduced, the labor intensity is reduced, the welding has a direction, the welding gun has a supporting function, the length of the weld after welding is increased, the excess height is reduced, the occurrence of unfused welds is eliminated, and the weld after welding is beautifully formed and can meet the requirements of the process drawings.
