Description

TECHNICAL FIELD

[0001] The utility model relates to cold storage vehicle plate processing equipment technical field, concretely related to a cold storage vehicle class automation welding device. BACKGROUND

[0002] In the production and manufacturing process of the refrigerated truck, the plate is the main component of the refrigerated truck body, and the connection quality directly affects the heat preservation performance, structural strength and service life of the refrigerated truck. At present, the connection of the refrigerated truck plate mainly adopts the welding mode to ensure the firmness and sealing of the connection. However, in the existing welding technology, whether manual welding or automatic welding with a welding gun along a fixed path, there are some problems to be solved.

[0003] The traditional manual welding method is flexible in operation, but requires higher welding skills of workers, and the welding quality is easily affected by factors such as worker fatigue and skill level fluctuation, so it is difficult to ensure the consistency and stability of welding.

However, this automatic welding method still needs manual positioning of the two plates and alignment of the side to be welded during implementation. Due to the large size and heavy weight of the plate, the operation is complicated when using hoisting tools for positioning and alignment, which not only wastes time and effort, but also makes it difficult to ensure the accuracy of positioning. Once the positioning is not accurate, it will lead to welding deviation, affecting the welding quality and the overall performance of the truck body.
