Automatic falling assembly device for bogie

Abstract

The invention discloses an automatic falling assembly device for a bogie. The device is used for solving the problems that the falling efficiency of the bogie is low, the manual labor intensity is high, the bogie is often not in the right position, and the efficiency and the assembly quality of a crown block and a bogie static pressure test bed are affected. The device comprises a workbench frame,a wheel pair positioning unit, a V-shaped groove seat plate, a wheel pair elastic positioning unit, a plurality of bearing box supporting units and an elevated device, wherein the wheel pair positioning unit is used for supporting a wheel tread formed by wheel pairs; the V-shaped groove seat plate is used for supporting a wheel flange formed by the wheel pairs; the wheel pair elastic positioningunit is used for fixing the wheel base; the bearing box supporting units can be used for supporting axle boxes formed by the corresponding wheel pairs; the elevated device is used for positioning andhoisting a framework assembly to a falling station; and after the framework assembly and the wheel pair assembly fall, a pressing-in mechanism is used for compressing a primary axle box spring of thebogie. The device is easy and convenient to use, high in falling efficiency and capable of achieving accurate falling and improving the assembly efficiency.

Description

technical field

[0001] The invention relates to the technical field of rail vehicle assembly equipment, in particular to an automatic bogie assembly device. Background technique

[0002] Bogie assembly is the key process of bogie assembly, which is mainly to assemble a frame component to two independent wheel sets to form a complete bogie. The bogie includes a wheel set composition 13 and a frame composition 12. The existing process is to use the manual control crane to lift the frame composition and the two wheel sets placed on the ground track for manual assembly. This process cannot ensure that the frame composition and the wheel set composition are aligned and assembled at one time, and manual labor is required. Repeated adjustments can only be completed. After the frame composition and the wheel set composition are dropped, for the bogie with steel springs and wheel set pivoting arm axle boxes, the existing technology cannot complete the positioning nodes of the wheel ...
