Abstract

The invention relates to the field of rail vehicle gauge changing, and provides a gauge changeable wheelset assembling device and assembling method. The device comprises a base, wherein the base is provided with a first sliding rail or a first sliding groove, a pair of axle supporting clamping devices are arranged on the base at intervals and each comprises a support, an axle positioning part, a pressing part and a locking part, the bottoms of the supports are provided with second sliding grooves or second sliding rails matched with the first sliding rail or the first sliding groove, the axlepositioning parts are fixed on the supports, and the pressing parts are in locking connection with the supports through the locking parts; a pair of wheel adjusting devices are arranged on the base atintervals, and both wheel adjusting devices comprise supporting seats and wheel positioning parts fixed on the supporting seats; and the bottoms of the supporting seats are provided with third sliding grooves or third sliding rails matched with the first sliding rail or the first sliding groove, and each wheel positioning part comprises a pair of baffles arranged on the corresponding supporting seat at intervals and a pair of supporting rolling wheels arranged between the corresponding pair of baffles. The device can realize quick and accurate assembly of a gauge changeable wheelset, and improves the assembly efficiency and the assembly precision.

Description

technical field [0001] The invention relates to the technical field of rail vehicle gauge change, in particular to a gauge change wheel set assembly device and an assembly method. Background technique [0002] The components of the variable gauge bogie wheel set adopt a new design structure, which is different from the traditional wheel set structure. The traditional wheel set adopts the interference fit between the wheel and the axle and is pressed by a press. The variable-gauge bogie wheel set adopts the clearance fit between the wheel and the axle, that is, the wheel can slide axially relative to the axle, so as to realize the change of the inner distance of the wheel on the wheel set to achieve the purpose of gauge change. At the same time, the distance between the wheel and the axle The gap between them is very small. Therefore, the assembling mode of the variable gauge wheel set is completely different from that of the traditional wheel set. [0003] However, at pres...
