Abstract

The invention relates to the technical field of railway vehicles, and discloses an automatic assembling and locating method of a railway vehicle side frame spring case. The method comprises the stepsthat according to the feature points of spring struts, and a locating block is additionally arranged on a material tray to ensure that the spring struts are accurately located on the material tray; Y-direction reference blocks corresponding to the same sides of the left spring strut and the right spring strut are additionally arranged on the left side and the right side of an automatic side frameassembling tool and serve as Y-direction locating reference of spring strut assembling; and X-direction reference blocks are additionally arranged at the two ends of the automatic side frame assembling tool and serve as X-direction locating reference of spring strut assembling. According to the problem that in the automatic assembling process of the side frame spring struts, locating is inaccurate, and the assembling consistency is poor can be solved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an automatic assembly and positioning method for a side beam spring barrel of a rail vehicle. Background technique [0002] With the gradual maturity and popularization of automated and intelligent production methods, automatic assembly has begun to be used in rail vehicle side beam assembly. Since the side beam spring tubes of high-speed EMUs have a circular structure, the spring tubes are placed on the material pallet. Due to the processing tolerance of the pallet positioning surface, there are gaps, the position of the spring cylinder changes during transportation, it is difficult to find the circular structural feature points during the automatic assembly process, and the tolerance of the lower cover of the side beam causes the positioning of the spring cylinder to be inaccurate. There are problems such as uneven assembly gaps, insufficient margins, and wrong edges. Th...
