Bogie air spring assembling tool and method for assembling air spring by utilizing same

Abstract

The invention relates to a bogie air spring assembling tool, comprising a baseboard, and supports at two sides of the baseboard. Supporting boards and slide bars are arranged on the supports, wherein the supporting boards can slide towards each other and are used for supporting air spring retaining rings, and the slide bars also can slide towards each other; vertical through holes are arranged at the front ends of the slide bars; retaining ring locating pins matched with air spring retaining ring screw holes are inserted in the vertical through holes; the baseboard is provided with a central hole locating pin matched with an air spring pedestal central hole and a screw hole locating pin matched with a first air spring pedestal screw hole; the center of the central hole locating pin and the centers of the vertical through holes of the two slide bars are throughout located on a same plane A which is perpendicular to the baseboard; an included angle between a plane B and the plane A equals to the base angles of an isosceles triangle formed by the air spring pedestal central hole and the two air spring retaining ring screw holes, wherein the plane B crosses the central hole locating pin centre and the screw hole locating pin centre and is perpendicular to the baseboard; and a connecting line of the two air spring pedestal screw holes is parallel to the plane A after air spring pedestals are placed on the baseboard. The bogie air spring assembling tool has the advantages of high assembling precision and high efficiency.

Description

technical field [0001] The invention relates to a bogie air spring assembly tool, which belongs to the technical field of rail vehicle bogie air spring assembly. Background technique [0002] In the bogies of rail vehicles, air springs are the key components connecting the upper and lower bodies. The pin hole of the air spring base is connected with the overhead spring seat plate of the bogie frame, and the closing plate of the air spring is connected with important parts of the upper body such as shock absorbers, tie rods, and corbels. After the air spring is assembled, the connecting line between the center pin of the closing plate and the air hole should It is perpendicular to the line connecting the two screw holes of the base. The assembly quality of the air spring is related to driving safety and is very important. In the past, air springs were assembled by manual scribing. Due to their large size and rubber parts (rubber parts should not be twisted), multiple people...
