Technical Field

[0001] The utility model relates to the technical field of refrigerated truck plate processing equipment, in particular to a welding device used for refrigerated truck plate production. Background Art

[0002] A refrigerated truck is a closed van transport truck used to maintain the temperature of frozen or fresh goods. It is a special refrigerated transport vehicle equipped with a refrigeration unit and a polyurethane insulated compartment. The panels inside the refrigerated truck need to be connected by welding.

[0003] A current welding device used in the production of refrigerated truck panels usually fixes the panel on a turning frame, then uses a driving device to rotate the turning frame, adjusts the position of the panel, and performs welding operations on both sides and various parts of the panel.

[0004] During the welding process, the vehicle plate is fixed on the flip frame, that is, one side of the vehicle plate is in contact with one side of the flip frame. When flip welding is performed, the contact position between the vehicle plate and the flip frame will be blocked by the flip frame, resulting in a blind spot in the welding. The staff needs to readjust the position of the vehicle plate before the vehicle plate can be completely welded. During this process, adjusting the position of the vehicle plate back and forth is not only troublesome, but also affects the efficiency of the vehicle plate welding process, so it needs to be improved.
