Description

Technical Field

[0001] The utility model mainly relates to the field of sheet metal welding, and in particular to a fixing tool for sheet metal welding. Background Art

[0002] Sheet metal is a comprehensive cold working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / combining, folding, riveting, splicing, forming (such as car bodies), etc. Its most notable feature is that the thickness of the same part is consistent;

[0003] There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction, and ultrasonic waves. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater, and in space. Welding can be dangerous to operators no matter where it is performed, so appropriate protective measures must be taken when welding. Possible injuries to the human body caused by welding include burns, electric shock, vision loss, inhalation of toxic gases, and excessive exposure to ultraviolet rays.

[0004] During the welding process, the sheet metal parts need to be fixed between the two sheet metal parts by using a fixing tool.

[0005] During the operation of the specific embodiment, the inventors found the following defects:

[0006] However, when sheet metal parts need to be welded to other sheet metal parts at different angles, the angles of the sheet metal parts need to be adjusted. However, after adjusting the angles of the sheet metal parts, the positions between the sheet metal parts will change, causing the sheet metal parts to be unable to be aligned, thus affecting the subsequent welding between the sheet metal parts.

[0007] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content
