Abstract

The invention relates to a kitchen garbage truck rear door assembling and welding method and assembling and welding tool. The kitchen garbage truck rear door assembling and welding method comprises the following steps that (1) a rear door hinged seat is placed at a set position on a truck bed; 2) an oil cylinder support is positioned and placed at the set position by taking the rear door hinged seat as a reference, and the rear door hinged seat and the oil cylinder support are arranged on the truck bed through spot welding; (3) a rear door is positioned and placed at the rear door closing position, one end of a telescopic assembly is hinged to the oil cylinder support, the telescopic assembly is located at the rear door closing position, a lower hinged lug on a rear door oil cylinder seatis positioned and hinged to the rear door hinged seat, an upper hinged lug of the rear door oil cylinder seat is hinged to the other end of the telescopic assembly, and then the rear door oil cylinderseat and the rear door are fixed together through spot welding; (4) the rear door is driven to overturn to simulate opening and closing of the rear door; and (5) if the rear door overturning processis smooth, the rear door hinged seat and the oil cylinder support are welded and fixed on the truck bed, the rear door oil cylinder seat and the rear door are welded and fixed together, and thereforerear door assembling and welding are completed.

Description

technical field [0001] The invention relates to a welding method and a welding tool for the back door of a kitchen garbage truck. Background technique [0002] During the garbage disposal process of the kitchen garbage truck, it is necessary to ensure the sealing performance of the kitchen garbage truck box to avoid problems such as wafting of peculiar smell and sewage dripping in the box, so as to reduce the secondary pollution to the surrounding environment. At present, the problems of odor wafting and sewage dripping from kitchen garbage trucks are mainly concentrated in the rear door of the carriage. Therefore, it is necessary to ensure that the gap between the rear door frame of the carriage and the surrounding area of ​​the rear door is uniform during welding, and then ensure that the sealing strip is installed between the rear door and the rear door frame. sealing performance. [0003] In the prior art, when welding the back door of the kitchen garbage truck, the hin...
