Aluminum alloy car body welding assembly tool

Abstract

The present invention proposes a welding assembly tool for an aluminum alloy car body, the aluminum alloy car body includes a chassis, a roof, a side wall and an end wall, side beams are arranged on both sides of the roof, including a fixing device for the chassis, and It is used to realize the fixed support and positioning of the underframe; the underframe deflection pull-down device is used to realize the prefabricated deflection curve of the underframe; the roof clamping and fixing device is used for clamping and positioning the roof during welding; the side wall assembly adjustment device , used to adjust the verticality and width of the side wall during the assembly process; the side beam assembly adjustment device is used to realize the tension and adjustment of the side beam; the roof clamping and fixing device includes a roof support frame, a setting On the roof supporting frame, an arc-shaped pressing device, a pressure block, an adjustable side clamping device for clamping the side beams on both sides of the roof, and A clamping device that clamps the roof up and down. The invention solves the problems of various types and poor versatility of aluminum alloy vehicle body welding tooling in the prior art.

Description

technical field [0001] The invention relates to an aluminum alloy vehicle body welding assembly tooling structure. Background technique [0002] With the development of society, rubber-tyred guide rail trams are more and more widely used. The main structure of the car body is a hollow aluminum alloy car body. The aluminum alloy car body is made of multiple parts. The main components include the chassis, The roof, the end wall and the side wall are provided with edge beams on both sides of the roof. When assembling and welding, it is usually necessary to weld the underframe, roof, end wall, and side wall together in sequence, and it is also necessary to consider whether various factors such as verticality and width after assembly meet the welding requirements during assembly. adjust. The existing tooling structure for aluminum alloy car body processing is realized by multiple single tooling, that is, the welding or assembly of each part of the roof and underframe requires a...
