Assembly welding tooling for door frame of driver's cab

Abstract

The invention discloses an assembly welding tooling for a door frame of a driver's cab. The assembly welding tooling comprises a support framework and a base board fixedly connected onto the support frame, wherein the support framework is in a frame structure, and comprises a cross beam and a longitudinal beam connected with the cross beam, a plurality of longitudinal pressing devices are arranged on the longitudinal beam, and a plurality of lateral compressing devices are arranged on the cross beam. According to the assembly welding tooling for the door frame of the driver's cab, the cross beam and the longitudinal beam of the door frame of the driver's cab are fixed on the base board by the aid of the lateral pressing devices and the longitudinal compressing devices, flatness and perpendicularity of the cross beam and the longitudinal beam are guaranteed, welding contraction deformation is prevented, welding difficulty is reduced, welding quality is improved simultaneously, enough rigidity and strength are provided, positioning is accurate, the cross beam and the longitudinal beam are clamped manually, assembly and disassembly are convenient, flexible and reliable, removing is convenient, and positioning can be adjusted according to welding deformation degree of products due to adoption of an adjustable structural design so as to meet requirements of dimensional accuracy of the door frame of the driver's cab after welding.

Description

technical field [0001] The invention relates to a welding tool, in particular to a driver's cab door frame welding tool. Background technique [0002] In the welding tooling of the door frame of the driver's cab of the railway vehicle, it is currently used to perform tack welding first, and then perform full welding. Tack welding is to locate the position of parts. In the past, the manual butt joint method was used. This method has a great impact on the deformation of the door frame of the driver's cab during full welding, which affects the welding quality and causes the potential danger of vehicle accidents. Moreover, the production efficiency is low and the operation is inconvenient. There is no tooling fixture for technicians that can solve such problems. [0003] This shows that the above-mentioned existing driver's cab door frame assembly welder is installed in use, obviously still has inconvenience and defective, and needs to be further improved urgently. In order t...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to overcome the defects existing in the existing driver's cab door frame welding tool, and provide a new type of driver's cab door frame welding tool. The positioning is adjusted to improve the welding accuracy, which is more suitable for practical use and has industrial application value
