Positioning tool for welding of vertical beams of cabinet

Abstract

The invention discloses a positioning tool for welding of vertical beams of a cabinet. The positioning tool for welding of the vertical beams of the cabinet comprises the vertical beams, a base, positioning plates and positioning pins. A plurality of square holes A are formed in the vertical beams and are distributed on the vertical beams at equal intervals in the length direction of the verticalbeams. The number of the vertical beams is four, and the vertical beams are connected through the positioning plates and are placed on the upper end face of the base. Square holes B are formed in thetwo ends of each positioning plate, and the size of the square holes B is the same as that of the square holes A. One end of each positioning pin sequentially penetrates through the corresponding square hole B and the corresponding square hole A from one side of the corresponding positioning plate and is connected with the corresponding vertical beam through a fastening screw. According to the positioning tool for welding of the vertical beams of the cabinet, the vertical beams are connected through the positioning plates and the positioning pins, and the square holes A in the vertical beams are positioned, so that the vertical beams are kept parallel; the lower end faces of the vertical beams are arranged vertically, the welding position is not affected by the positioning tool during welding, and welding can be completed at a time, so that the working efficiency is improved; and meanwhile, the influence of high-temperature changes to the welding quality can be avoided.

Description

technical field [0001] The invention belongs to the field of welding and positioning tooling, and in particular relates to a welding and positioning tooling for vertical beams of cabinets. Background technique [0002] At present, when producing cabinets, etc., the vertical beams and bases of the cabinets are processed and formed separately, and then the vertical beams and bases are welded. Since the vertical beams of the cabinets and other products are formed by bending steel plates, the workpiece is prone to internal stress, resulting in The workpiece has angular error and straightness error, and the error degree of different curved sections is different. During welding, the positioning method of bow clamp and right-angle positioning plate is often used, and the vertical beam is clamped on the right-angle positioning plate by using the bow clamp to keep the vertical beam vertical, but the vertical beam is easily deformed under the action of clamping force, thus affecting ...
