Description

Technical Field

[0001] The utility model relates to the field of welding, in particular to a welding tool for a dump truck assembly vehicle. Background Art

[0002] In order to save labor for unloading, most existing loading vehicles will install a dump structure under the vehicle. The dump structure of this assembly vehicle is mostly welded using multiple structures. In order to ensure the accuracy of the welding position, a welding tool for the dump assembly vehicle is required to fix the dump structure.

[0003] Most of the existing welding tools for dump trucks use guide rods to connect the positioning base and the driven base to ensure that the driven base will not have angular displacement deviation during movement. The moving distance is controlled by the meshing connection between the driven gear of the rotating motor output shaft and the ruler bar. After the bottom material is placed on the bottom fixing device above the positioning base and the driven base, the side material is clamped and fixed using the side fixing device. The welding position of the bottom material and the side material is determined by adjusting the angle of the side fixing device, and finally the two are welded together.

[0004] Although this type of welding tooling can ensure the stability of welding, most of the bottom materials are clamped on the bottom fixing block using tools, which limits the clamping position and makes it easy for the material to partially warp. Similarly, in order to ensure that welding is not affected, the side fixing device mostly fixes the position on one side of the side material, so that the welding position of the side material may deviate due to the warping of the material, thereby affecting the accuracy. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the welding tooling of the existing dump assembly vehicle cannot achieve uniform positioning when positioning and fixing the material, so that the welding edge of the material will be warped during welding.

The gap between the diverter air holes of the bottom surface fixing block is provided with a sealing groove for storing the sealing strip. The air inlet of the diverter air hole passes through the bottom surface table of the positioning base and the driven base. The side fixing device is connected to the working table of the positioning base and the driven base through a pin structure. The side fixing device includes a telescopic rod for supporting the movable electromagnetic table to rotate at an angle, and a plurality of electromagnetic fixed suction cups for fixing welding materials. The movable electromagnetic table and the positioning base are connected to both ends of the telescopic rod through a pin structure.

[0007] As an improvement, the guide rod is connected to the positioning base through an electric welding device, and the guide rod is slidably connected to the internal through hole of the driven base through body contact.

[0008] As an improvement, a moving wheel is provided below the driven base, and a slide rail for guiding the moving wheel to move is provided on one side of the positioning base.

[0009] As an improvement, the rotating motor is connected to the side wall of the driven base via a bolt structure, and the output shaft of the rotating motor is connected to the driven gear via a connecting key.

[0010] As an improvement, the ruler bar is connected to the side wall of the positioning base by welding, and the ruler bar is connected to the driven gear by gear meshing.

[0011] As an improvement, the rotating motor and the movable electromagnetic table are both connected to a power source via wires.

[0012] Compared with the prior art, the utility model has the following advantages: the device absorbs the bottom material onto the bottom fixed block through the suction force generated by the diverter pores inside the bottom fixed block; the sealing strip forms a closed loop in the sealing groove, thereby forming a coil (the size of the coil is slightly smaller than the bottom area of ​​the bottom material) formed by the sealing strip, and a vacuum state is formed between the diverter pores inside the coil and the bottom material, thereby ensuring the stability of the bottom material; the side material is absorbed onto the movable electromagnetic table through a plurality of electromagnetic fixed suction cups, thereby ensuring that the side material will not warp.
