Welding assembly tool and method for electric wheel dumper cargo tank

Abstract

The invention discloses a welding assembly tool and method for an electric wheel dumper cargo tank. The welding assembly tool comprises a cargo tank front plate welding assembly welding tool and a cargo tank assembly tool. The cargo tank front plate welding assembly welding tool comprises a saddle positioning base, first front plate supporting base sets, second front plate supporting bases, first pressing blocks, a fixed pressing block and a movable pressing block. The cargo tank assembly tool comprises bases, front plate welding assembly positioning frames, a saddle positioning frame, a left side plate positioning frame, a left side plate inclined supporting frame, a right side plate positioning frame, a right side plate inclined supporting frame, rear wane supporting frames, hinged bases, a saddle pressing block and bottom plate pressing blocks. The welding assembly method for the cargo tank includes the steps that a cargo tank front plate welding assembly is welded; the cargo tank is assembled. According to the structure and the method, before welding, all parts of the cargo tank can be accurately positioned, and the cargo tank can be prevented from deforming severely in the welding process.

Description

technical field [0001] The invention relates to a welding and assembling tool and a welding and assembling method for a cargo box of an electric wheel dump truck. Background technique [0002] Such as figure 1 As shown, the cargo box 100 includes a bottom plate 101 , a rear rocker plate 102 , a left side plate 103 , a right side plate 104 and a front plate 105 . The rear rocker 102 and the bottom plate 101 are integrally bent and formed, and the rear rocker is upturned from the front end to the rear end; the left side plate 103 includes a left inclined side plate whose lower end is welded to the bottom plate 101 and the rear rocker 102 and connected to the left The left vertical plate at the top of the inclined side plate is equipped with a left longitudinal beam 106 on the outer surface of the left vertical plate, and a left rib 107 is welded between the base plate 101 and the left longitudinal beam. The right side plate 104 includes a right inclined side plate whose lowe...

AI Technical Summary

Problems solved by technology

The front plate 105 is welded on the front end of the base plate 101, and the two sides are respectively welded with the left side plate 103 and the right side plate 104; a saddle seat 108 is welded on the front plate 105, and the front plate, saddle seat, reinforcing beam, etc. form the front plate welding assembly. When the cargo box 100 descends and gradually approaches the rear frame, the return position of the cargo box 100 is guided and positioned under the action of the saddle seat 108. Therefore, the position accuracy of the saddle seat 108 and the front plate 105 is very important. If the position accuracy of each part of the cargo box is low, the assembly error between the cargo box 100 and the rear frame will be large, and even the phenomenon that it cannot be installed will be caused.
