Abstract

The invention relates to the assembly field of axle box spring, and discloses an axle box spring pre-assembly device, comprising an upper pressing plate, a lower pressing plate, a guide column, a pressing block and a sleeve. The circumferential direction of the lower pressing plate is provided with threaded holes corresponding to the connecting holes of the guide column plate one by one, the lowerend of the guide column is provided with external threads and is connected with the threaded holes one by one, and the guide column passes through the connecting holes to realize that the guide column plate is installed on the lower pressing plate; The circumferential direction of the upper pressure plate is provided with a corresponding through hole through which the guide pillar passes, the upper pressing plate is provided with a first central hole matched with a guide post of a series of rubber springs, The press block is used for being placed in the guide post inner hole of a series of rubber springs, the press block exerts downward pressure on the axle box spring, compresses the axle box spring, after being compressed to a set height, the axle box spring is sleeved on the guide postabove the upper press plate by a sleeve and locked by a locking member. The invention can meet the phase requirement when the axle box spring is pressed and assembled, and simultaneously protects therubber part of a series of rubber springs from being forced.

Description

technical field [0001] The invention relates to the technical field of axlebox spring assembly, in particular to an axlebox spring pre-assembly device. Background technique [0002] Ordinary axle box springs do not have phase requirements, and are mainly composed of a set of inner and outer steel springs, and upper and lower splints. When press-fitting ordinary axlebox springs, you only need to apply force to the upper and lower splints. After the axlebox springs are compressed to the specified height, install the process bolts, and then the press-fitting of the axlebox springs is completed. [0003] The axle box spring of the EMU is mainly composed of a steel spring, a series of rubber springs, spring upper splints and guide post plates. There are strict phase requirements between the first series of rubber springs and the spring upper splints, and they cannot be corrected during press-fitting. The rubber part of the rubber spring exerts too much pressure, and the axle box...
