Processing method for welding supports on irregular plate

Abstract

The invention relates to a processing method for welding supports on an irregular plate. The method comprises the following steps of: (1) bending the irregular plate to form a required shape; (2) mounting a template on a side face of the irregular plate; (2) respectively penetrating more than two positioning pins which are arranged on the template in connecting holes of the supports, and positioning the supports, wherein each support is an eccentric wheel; (4) rotating the supports along the respective positioning pin, so that edges of the supports are connected with the irregular plate; and (5) welding the supports and the irregular plate, and removing the template. The supports have an eccentric wheel structure and are positioned by the positioning pins, so that the supports can rotate along the central axis of the connecting holes under positioning of the positioning pins; and therefore, the distance between the connecting holes on the supports and the irregular plate can be changed, the structure is reasonable, the welding distance between the supports and the irregular plate can be rapidly and accurately controlled, the operation is convenient, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a processing method for welding a support on a special-shaped plate, which belongs to the technical field of mechanical processing. Background technique [0002] The special-shaped board is usually used to protect the main engine, and the special-shaped board is formed by bending or stamping. There are processing errors in the processing of the special-shaped board, and the shape of the special-shaped board will change due to improper transportation and storage. Irregular, but there are usually multiple supports fixed on the special-shaped plate, and the connectors connected to the special-shaped plate are installed on each support through multiple fasteners. , often due to the large error or deformation of the special-shaped plate, when the support is welded on the special-shaped plate, the welding position of the support will change due to the change of the distance between the support and the special-shaped plate, which will...

AI Technical Summary

Problems solved by technology

However, the size error of the motor protection case of the bending process is relatively large, especially in the improper placement and transportation process. The motor protection case will be deformed after being subjected to external pressure. When the support needs to be welded on the inner or outer wall of the motor protection case, The deformed motor protection case also changes the distance between the positioned support and the motor protection case. When the distance between the threaded hole of the support and the motor protection case is too far, the two cannot be welded; and when the support If the distance between the threaded hole of the seat and the motor protection shell is too close, the support will interfere with the motor protection shell and cannot be welded, which not only increases the difficulty of welding the support, but also seriously affects the welding production efficiency
