Cultivator fender assembly and welding tool

Abstract

The invention discloses a cultivator fender assembly and welding tool, which comprises a bottom plate, supporting columns, limiting blocks, a shim block, a fixed block, a movable pressing block and a compaction device, wherein the supporting columns are distributed on the bottom plate in a height adjustable manner and used for supporting two parts to be assembled and welded with fenders; and the limiting blocks are positioned on the edges of the two parts to be assembled and welded with the fenders, fixedly distributed on the bottom plate and used for limiting the freedom degree of the horizontal direction of the two parts to be assembled and welded with the fenders. By adopting a multi-point quick positioning structure comprising positioning in the vertical and horizontal directions and on the edges and combining a quickly driven mobile positioning structure, the welding positioning process is standardized and the form and position accuracy of welding can be ensured; and the tool is provided with the supporting columns capable of adjusting the height according to the requirement of the plate-like welding structure, so that bottom positioning is realized, the tool has adaptability to the irregular plate-like structure, the work efficiency is improved, the service life of the tool is prolonged, the labor intensity of an operator is reduced, and the production and using costs are saved.

Description

technical field [0001] The invention relates to a welding processing auxiliary device, in particular to a fender assembly welding tool for tillage machines. Background technique [0002] Welding process is a way of combining and fixing different parts by welding. For the welding between small parts, the self-weight is light, and the positioning effect is not good, which is prone to deviation. Unlike other connection methods, welding is a non-detachable connection. If there is a large accuracy error, it will affect the quality of the entire product and even be scrapped. [0003] In the prior art, due to the relatively large area of ​​the cultivator’s fender, it is difficult to position during the welding process. Generally, the operator’s experience is used to ensure the shape and position error. Generally, spot welding is used for positioning first, and then overall welding is performed, which affects the welding accuracy. The production efficiency is low, the welding proc...

[0003] In the prior art, due to the relatively large area of ​​the cultivator’s fender, it is difficult to position during the welding process. Generally, the operator’s experience is used to ensure the shape and position error. Generally, spot welding is used for positioning first, and then overall welding is performed, which affects the welding accuracy. The production efficiency is low, the scrap rate of welding processing is high, the processing cost is increased, and the labor intensity is increased
