Description

Technical Field

[0001] The utility model relates to the technical field of subway car body manufacturing, in particular to a welding device for subway car body manufacturing. Background Art

[0002] The subway is a fast, high-capacity, electric-powered rail transit system built in the city. The subway runs on fully enclosed lines, both underground and above ground. The lines in the central city are generally located in underground tunnels. The basic forms of the subway network include single-line, single-loop, multi-line, and spider web. Each subway line consists of interval tunnels, stations, and ancillary buildings. The welding process is indispensable in the manufacture of subway car bodies. Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. The various components of the car body can be combined and spliced ​​through the welding machine to form a complete subway car body. In the process of manufacturing subway car bodies, the car body sheet materials are generally larger, and when welding, they often cause certain welding inconveniences due to their large size. Therefore, we need to continuously innovate and create existing welding devices for subway car body manufacturing.

[0003] The defects of a welding device for manufacturing subway car bodies in the prior art are: Patent document CN213614869U discloses "a special welding device for car body steel structure, involving the field of steel structure welding, including a main body, a clamping structure, and a lifting and flipping structure.

By starting the No. 1 cylinder, the No. 1 push rod is pushed to move by the No. 1 cylinder, and the No. 1 push rod drives the clamping rod to move. The clamping rod will move along the direction of the connecting block. Since the clamping rod is an L-shaped structure, one end of the clamping rod will be close to the other clamping rod, so that the clamping rod clamps the weldment, and then the No. 1 motor is started to drive the screw connected to its output end to rotate, so that the movable rod moves, thereby moving the welding gun to a specified position for welding, thereby achieving the purpose of clamping the weldment and improving work efficiency."
