Welding tool for bucket assembly of garbage truck and assembling process

Abstract

The invention relates to a welding tool for a bucket assembly of a garbage truck and an assembling process. The welding tool comprises a tool platform, an upper cover divisional tool, a guide rail divisional tool and a bucket divisional tool, wherein the upper cover divisional tool comprises a positioning support, a front cross beam positioning set, a rear cross beam positioning set, an oil cylinder seat plate positioning set, a reinforcing tube positioning set, a reinforcing beam positioning set and an obtuse body positioning set, the bucket divisional tool comprises a frame positioning set,a roller positioning set, a pull lug positioning set, mounting plate positioning sets, guide rail positioning sets and a cross beam positioning set, and guide rail positioning sets of the guide rail divisional tool comprise reference inner plates which are arranged at intervals in front and back and pressing assemblies which are arranged at intervals in front and back. According to the welding tool, the upper cover divisional tool is used for positioning and welding an upper cover assembly, the guide rail divisional tool is used for positioning and welding a guide rail assembly, the bucket divisional tool is used for positioning and welding a bucket frame assembly and a pressing barrel frame assembly, the upper cover assembly, the guide rail assembly, the bucket frame assembly and the pressing barrel frame assembly are welded separately and then assembled to be together, and therefore the parallelism and the coaxiality of the parts can be effectively guaranteed, the assembling difficulty is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of garbage truck assembly, in particular to a tailor-welded tooling and an assembly process for a garbage truck bucket assembly. Background technique [0002] Garbage generally refers to unnecessary or useless solid and fluid substances, which can be seen everywhere in people's daily life or production, but the cleaning and cleaning of such solid waste is a relatively cumbersome task. In order to improve the efficiency of garbage collection and reduce transportation costs, side-mounted compression garbage collection vehicles have appeared on the market. [0003] The side-mounted compression garbage collection vehicle includes a bucket assembly located on the side of the car body. The support beam is fixedly installed on the side of the car body and has a rail groove on it. The bucket hanging frame assembly and the barrel pressing frame assembly are respectively slid and fitted in the rail grooves of the gui...

Problems solved by technology

If the above requirements are not met, it may cause the relevant parts to be tilted during the working process, the force will be uneven, and it will be easily damaged, making it difficult to achieve the desired effect

[0005] In the assembly of the bucket assembly, the previous practice is to rely on manual assembly and marking of parts during the welding process, which is difficult to assemble and takes a long time to assemble, which makes the production efficiency of assembly and welding low and becomes the bottleneck of production.

Moreover, relying solely on manual welding, due to the different welding levels, it is difficult to unify the benchmarks, not only the dimensional accuracy and shape and position tolerances are easy to be out of tolerance, but also affect the appearance

The precise requirements of coaxiality and parallelism between the main components cannot be guaranteed, and the interchangeability of parts is poor, which affects the assembly quality, increases maintenance costs, and is not convenient for after-sales service maintenance.
