Abstract

The invention relates to a pre-pressing and assembling device and method for a tumbler journal box. The pre-pressing and assembling device for the tumbler journal box comprises a framework positioning and press-assembling guide device and a gantry frame trolley, wherein the framework positioning and press-assembling guide device comprises a fixing plate, and positioning pins which are matched with machined holes in the ends of a tumbler journal box device framework and guide pins which are in the same direction as a spring device and a tumbler of a compression tumbler journal box device are arranged on the fixing plate; and a pressure device which can stretch and retract longitudinally to compress the spring device of the compression tumbler journal box device is arranged on the gantry frame trolley. The device and method are a comprehensive platform and method which can achieve framework positioning, spring device compressing and tumbler guiding and assembling, and since a framework can be positioned, it is guaranteed that the pressure direction of the pressure device is accurate; and since the pressure device can be used for compressing a spring, the tumbler can be guided in the pre-pressing process, the pre-pressing directions of the spring device and the tumbler are guaranteed accordingly, and it is guaranteed that a joint shaft of the tumbler is mounted in a tumbler seat clamping groove accurately.

Description

technical field [0001] The invention relates to an assembly device and method, which belong to the technical field of a rotary arm type axle box, and in particular to a rotary arm type axle box preload assembly device and method. Background technique [0002] The pivoting arm axle box structure is widely used in railway passenger cars, engineering vehicles, trucks and subway bogies. Due to the certain amount of pre-compression of the axle box spring, the assembly accuracy of the pivoting arm joints is high, and the assembly is difficult and time-consuming. [0003] As the main structural part of the bogie, the pivot box is the key process of bogie manufacturing. The pivoting arm axle box is mainly assembled with the spring damping device and the pivoting arm, wherein the spring damping device is installed in the axle box mounting seat, and the pivoting arm shaft is placed in the mounting groove of the pivoting arm seat, and the axle box is used to lift and cover and fasten ...
