Description

TECHNICAL FIELD

[0001] The utility model relates to orthopaedic equipment technical field especially relates to a vehicle body orthopaedic device. BACKGROUND

[0002] In the manufacturing and processing of products in the modern manufacturing industry, many products are processed and manufactured by adopting welding process, but in the process of implementing welding, welding deformation becomes a problem in welding in the manufacturing industry, especially after the welding of sheet metal parts is completed, the deformation of the parts is large, some key dimensions change, which affects the assembly and use of the product, and how to solve or control the welding deformation problem becomes a difficult problem that needs to be overcome in the welding manufacturing industry.

[0003] In the current tractor body manufacturing, the floor part of the body includes a front fender and a rear fender, and the front fender and the rear fender are integrally formed by a mold, and the distance between the front fender and the rear fender is defined as the middle inner fender distance. Because the floor part is composed of multiple steel sheet metal parts spliced by welding process, the plate used is relatively thin, so a large deformation is easily generated in the welding process, so that the main body of the floor is not a flat plane.

[0004] It is explained that in the welding process, the body structure of the front fender and the rear fender will not change, only the deformation of the main body of the entire floor will occur due to welding, and this deformation will cause the change of the middle inner fender distance of the body, and this deformation will cause the interference or collision between the body and the instrument table of the tractor in the body assembly stage.

[0005] In order to ensure the overall assembly quality of the tractor, the existing production process is to correct the deformation caused by welding by using a lever by manual operation after the body is welded, and the internal size of the body is adjusted to meet the requirements of the design drawing.

[0006] Although this method can solve the problem of size deviation to a certain extent, since it completely depends on manual operation and personal experience, the force control is not easy in the operation process, and the concave or convex caused by knocking is often left on the surface of the body plate, thereby affecting the appearance quality of the product; in addition, since the edge of the body plate is sharp, there is a risk of cutting the arm in the process of manual correction, and the safety of the employees cannot be effectively guaranteed; in addition, the manual correction is low in efficiency and high in labor intensity, which is contrary to the concept of human engineering pursued by the modern manufacturing industry.
