Abstract

The invention discloses a chassis assembling tool and method, and belongs to the technical field of railway wagons. According to the chassis assembling tool, two traction beam supporting frames are both fixedly arranged on an assembling datum platform, and two sleeper beam supporting frames are arranged between the two traction beam supporting frames; the two sleeper beam supporting frames are both fixedly arranged on the assembling reference platform, and the distance between the two sleeper beam supporting frames is set. Two positioning plates are arranged on the sleeper beam supporting frame, the distance between the two positioning plates is set, two positioning pieces are arranged on the positioning plates, and the distance between the two positioning pieces is set; the plurality of main beam supporting frames are fixedly arranged on the assembly reference platform, and the plurality of main beam supporting frames are arranged between the two sleeper beam supporting frames; two limiting plates are arranged on the main beam supporting frame, and the distance between the two limiting plates is set. Two side beam supporting plates are arranged on the main beam supporting frame, and the heights of the side beam supporting plates are set. According to the chassis assembly tool and the assembly method, the size precision can be guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of railway wagons, in particular to an underframe assembly tool and an assembly method. Background technique [0002] In the prior art, the assembly process of the underframe is to hang the two ends of the head and pull the pillow to form it on the platform, manually use a 20m tape measure to measure, measure the distance between the pillow and the center of the pillow, and adjust the diagonal manually with a screw rod , the size meets the requirements. Fix the pillows at both ends, and then draw lines to assemble the main beam, side beams and cross beams. [0003] However, the dimensional error of the manual line drawing operation is large. After the base frame is assembled and welded, the center disc distance, diagonal line, and deflection values ​​exceed the technical requirements. , Low production efficiency. Contents of the invention [0004] The invention provides a bottom frame assembly tool and ...
