Abstract
The invention discloses a general assembly tool for an M vehicle body of a tram. The general assembly tool for the M vehicle body of the tram comprises a bottom beam, a first tool assembly and secondtool assemblies, wherein the first tool assembly is arranged in the middle of the bottom beam, and the second tool assemblies are arranged at the both ends of the bottom beam. The first tooling assembly is used for clamping a bottom frame and a front end frame of the vehicle body, and the second tool assemblies are used for clamping side walls and a ceiling of the vehicle body. The second tool assemblies comprise column frames connected with the bottom beam and movable frames which can slip along the bottom beam in the axial direction. According to the process requirements, the bottom frame isfirst positioned correctly, then the two sides of the wall are assembled, and then the ceiling, a back end wall and the front end frame are assembled in sequence. The first tooling assembly is used for clamping the bottom frame and the front end frame of the vehicle body, and the second tool assemblies are used for clamping the side walls and the ceiling of the vehicle body. The positioning and assembly are firm and the assembly precision is high in the positions, between an end frame, the bottom frame, the side walls, the ceiling and a rear end wall in a two-to-two mode, and the thermal deformation during welding and the cooling shrinkage deformation after welding are effectively restrained to complete the assembly process of the vehicle body.
Description
technical field [0001] The invention relates to car body assembly, in particular to a tramcar M car body assembly tooling and its technology. Background technique [0002] In car body assembly, such as train body and automobile body, the car body usually includes an underframe, a ceiling, a front frame, a rear end wall and a side wall, and the side wall includes a number of columns. Trains are used on special tracks, and all trains on special tracks need to ensure that their size deviations are extremely small. [0003] In the prior art, in the welding process of the car body, the positioning and clamping are not done well, there is no positioning and clamping, or the positioning and clamping is not in place, resulting in thermal deformation during the welding process and cooling shrinkage deformation after welding. large deviation. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide...
