The invention provides a railway flat car welding positioning device, a production line and a welding method, belonging to the field of railway flat car manufacturing. The railway flat car welding positioning device includes a positioning mechanism, a reference laser unit and an indicating laser unit. The positioning mechanism includes a main frame body and a movable part arranged on the top of the main frame body, and an assembly space for accommodating the vehicle body is formed under the movable part. The reference laser unit is arranged on the movable part and driven by the movable part to project a reference projection on the top surface of the vehicle body. The indicating laser unit is arranged on the movable part and driven by the movable part to project a positioning projection on the top surface of the vehicle body. After the reference projection and the reference mark are positioned, the positioning projection indicates the designed installation position on the top surface of the vehicle body. The production line and welding method adopt the above-mentioned railway flat car welding positioning device. The welding positioning device, production line and welding method of the railway flat car of the present invention can avoid the deformation of the positioning tooling caused by high welding temperature, and improve the positioning accuracy of the accessories.
Description
technical field [0001] The invention belongs to the technical field of railway flat car production and manufacturing, and more specifically relates to a welding positioning device for a railway flat car, a production line and a welding method. Background technique [0002] In the production process of railway flat cars, the car body is generally produced first, and then various accessories are welded on the car body, such as locking devices and so on. [0003] The current welding method of car body accessories is generally to attach the accessories to the car body, then use the positioning tool to locate the accessories at the designed installation position on the car body, and then weld the accessories and the car body together. Using this welding method, because the positioning tool is in contact with the accessories and the car body, the high temperature of welding will deform the positioning tool, resulting in the often misalignment of the welded accessories, and the pos...
