Abstract

The invention provides a chassis assembling fixture. The chassis assembling fixture comprises a base frame which is used for assembling a chassis of a box car. The base frame includes a first base frame body used for assembling the chassis of an open wagon and a second base frame body which is detachably connected with the first base frame body. The first base frame body is longer than the second base frame body. The first base frame body and the second base frame body each comprise two parallel I-beams which are arranged in a spaced mode. A plurality of connecting plates are evenly arranged between the two I-beams of each base frame body. The base frame is fixedly provided with end beam assembling assemblies, a middle beam assembling assembly, bolster beam assembling assemblies and cross beam assembling assemblies. According to the chassis assembling fixture provided by the invention, the first base frame body and the second base frame body detachably connected with the first base frame body are arranged, so that the application range of the chassis assembling fixture is effectively enlarged, that is, the first base frame body is applicable to assembling of the chassis of the open wagon, and the overall base frame is applicable to assembling of the chassis of the box car; accordingly, the practicality of the chassis assembling fixture is improved, and meanwhile the use stability and reliability of the chassis assembling fixture are also improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle production equipment, in particular to an underframe group pairing fixture. Background technique [0002] In recent years, with the rapid development of railway construction, railway vehicles are constantly developing new vehicles in order to meet the needs of heavy load and high speed, and the replacement of vehicles is accelerating year by year. Boxcars and gondolas are the most common types of freight cars in railway transportation. They undertake 80% of my country's railway freight transportation. The importance of these two vehicles determines their requirements for continuous upgrading. [0003] At present, the base frame group is mainly used to weld and assemble the tool to the base frame. The existing base frame group to the tool includes two longitudinal beams arranged in parallel, and a positioning system is slidably arranged between the two longitudinal beams through a clamping dev...
