[0001] The invention relates to the technical field of welding, and in particular to an auxiliary device for welding a steel barrel. Background Art

[0002] The manufacture of steel drums involves a welding process that connects the two open ends of the rolled steel sheet together to form a complete barrel shape.

[0003] The existing welding of steel drums involves spot welding of resistance welding, that is, using two electrode heads to process the two open ends of the steel plate. Generally, a steel drum usually requires 2-5 spot welding, the purpose of which is to fix and limit the two open ends of the steel plate so that the two open ends are in a linear fixed state, which is convenient for the subsequent seam welding process of the steel drum.

[0004] Resistance welding uses the resistance heat effect generated by the current flowing through the contact surface of the workpiece and the adjacent area to melt or plasticize the workpiece, so that the two open ends of the steel plate are combined. Therefore, the area where the electrode head contacts the steel plate and the area where the two open ends of the steel plate contact each other must be kept clean. Dust is everywhere in the factory, and workers generally use cleaning cloths to manually clean the steel plates. However, the steel plates are large and the workers' arms cannot completely cover them, so they cannot clean all the aforementioned areas well, which can easily lead to loose welding and thus cause quality problems in the steel barrels.

[0023] Specifically, the support frame 12 has two ends, the end close to the mounting plate 13 is set as the first end, and the other end is set as the second end. The first end is in contact with the ground, while the second end is higher than the ground and does not contact the ground.

[0024] refer to Figure 5 and Figure 7 In order to facilitate the elastic sponge 22 to wipe the welding area of ​​steel plates of different thicknesses within a certain range, the elastic sponge 22 makes a certain movement in the vertical direction. The cleaning member 21 has two horizontal plates 23 and a vertical plate 24. The two horizontal plates 23 are fixedly connected to the two sides of the vertical plate 24 respectively. The horizontal plate 23 has a chamber 25. The chamber 25 runs through one side of the horizontal plate 23. The chamber 25 is connected to a slide plate 27 through a plurality of elastic members 26. The slide plate 27 is located in the chamber 25 and is slidably connected to the inner wall of the chamber 25. One side of the slide plate 27 is fixedly connected to the elastic sponge 22.

Specifically, the elastic paddle 43 is located between the corresponding two elastic sponges 22, and the vibration motor 42 is started to drive the elastic paddle 43 to vibrate at a high frequency, thereby shaking off the dust flowing down after the elastic sponge 22 wipes. In addition, the two metal conductive plates 47 have electrostatic adsorption capabilities, so that the shaken dust is electrostatically adsorbed by the two metal conductive plates 47 to prevent the dust from scattering, thereby achieving the cleaning process of the cleaning section 20.
