Device and method for preventing welding deformation of supporting burden

Abstract

The invention provides a device for preventing welding deformation of a supporting burden of a combine harvester, and is applicable to the technical field of combine harvesters. The invention also relates to a method for preventing welding deformation of the supporting burden. The device for preventing the welding deformation of the supporting burden comprises a device base (1), a supporting block (2) and force application devices (3), wherein the supporting block (2) is arranged on the device base (1); and the force application devices (3) capable of applying a downward pressure to two end parts of a supporting burden (9) arranged on the supporting block (2) are arranged on two sides of the supporting block (2). By the device for preventing the welding deformation of the supporting burden, the supporting burden is hardly deformed after welding, the supporting burden is reliable and useful, the whole supporting burden is prevented from being scrapped, and the device is simple in structure and reliable in performance in the using process.

Description

technical field [0001] The invention belongs to the technical field of combine harvesters, and more specifically relates to a device for preventing welding deformation of a support load of a combine harvester. The invention also relates to a method for preventing welding deformation of a support load of a combine harvester. Background technique [0002] The supporting load is an important part of the frame of the combine harvester, and the supporting wheels need to be welded on the supporting load to ensure the normal operation of the harvester. However, when the rollers are welded to the supporting load, the supporting load is easily deformed during the welding process, so that after welding, it becomes a downwardly concave arc structure in the middle. At present, when the rollers are welded to the supporting load, there is no device and method for preventing the deformation of the supporting load. However, the deformation of the heavy load is serious, which seriously affe...

AI Technical Summary

Problems solved by technology

However, when the rollers are welded to the supporting load, the supporting load is easily deformed during the welding process, so that after the welding is completed, it becomes an arc-shaped structure with a concave middle part.

At present, there is no device and method to prevent the deformation of the supporting load when the supporting wheels are welded to the supporting load

However, the deformation of the heavy load is serious, which seriously affects the quality of the heavy load, and often leads to the scrapping of the entire heavy load.
