Tool for trailer welding

Abstract

The invention relates to a tool for trailer welding. The tool comprises a base, and further comprises a plurality of groups of rotary lock assemblies, a pushing positioning assembly, right angle limiting pieces, a support positioning assembly and a frame body positioning assembly, wherein a plurality of sets of buckle units are arranged above the base, each set of the buckle units comprises a first saddle-shaped buckle and a second saddle-shaped buckle which are connected with a corresponding first limiting seat and a corresponding second limiting seat respectively, the extension lines of thecenter lines of the first saddle-shaped buckles and the second saddle-shaped buckles intersect and are perpendicular in a horizontal plane, the rotary lock assemblies are arranged on the base, each rotary lock assembly is matched with the corresponding buckle unit in a clamped mode, the pushing positioning assembly is connected with the right-angle limiting pieces at one end of the base, the support positioning assembly is connected with the base, and the frame body positioning assembly is used for positioning a frame body of a vehicle frame. Multi-point positioning is achieved for workpiece placement, the problems of welding position deviation and poor welding precision cannot be caused, the welding qualification rate is increased, the production efficiency is improved, and the situationthat preset work is completed within the construction period is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a tooling for trailer welding. Background technique [0002] In industries such as transportation, trailers are often used to transport various items. In actual work, when transporting goods, the flatness of the frame of the trailer is required to be high. If there is any unevenness, it will affect the slipping and dumping of the product in the subsequent transportation process, which greatly affects the transportation efficiency and safety of transportation. [0003] There is an existing one such as the attached Figure 8 As shown in the frame assembly, the frame assembly includes a rectangular frame frame, and the four corners of the frame frame are fixed with limit seat units, and the four sets of limit seat units are symmetrically arranged in pairs. Each group of limit seat units includes a first limit seat and a second limit seat; one end of the fr...

AI Technical Summary

Problems solved by technology

[0004] However, due to the large size of the frame of the body and the high precision required, manual welding is generally used, but under relatively strict process requirements, the welding is difficult. During welding, the welding position is generally placed manually by the staff. The welding position is offset, the welding accuracy cannot be guaranteed, resulting in long processing time, low pass rate, low production efficiency, and the construction period cannot be effectively guaranteed, etc.
