Description

Technical Field

[0001] The utility model relates to the field of trailer production and processing, in particular to an assembly welding device for a semitrailer axle and suspension. Background Art

[0002] During the welding process of the semi-axle and suspension of the semi-trailer, the axle and the suspension are large in size and heavy in weight, so it is necessary to use tooling to align them, and it is difficult to complete the alignment operation by manual labor alone. Usually, the placement positions of the axle and the suspension on the welding tooling are very close. For example, a welding device for the axle and the suspension of a semi-trailer disclosed in the utility model with application number 202222382041.4 is used in the assembly welding process of the axle and the suspension, including a base plate, and the base plate is provided with a plurality of supports to respectively form limiting grooves for the axle and the suspension, thereby limiting and fixing the axle and the suspension placed therein. However, in the actual operation process, the axle and the suspension are transferred and placed by hoisting. In the process of falling into the limiting groove, due to the extremely close placement positions, the components placed later are very likely to touch the components that have been placed, and the components that are touched crooked need to be corrected by manpower, which increases the difficulty of placing the components in the tooling process.
