Abstract

The invention provides a swing bolster node positioning and press-fitting device and press-fitting method. The swing bolster node positioning and press-fitting device comprises a guiding and press-fitting part and a bottom plate, wherein the guiding and press-fitting part comprises a node supporting seat, a guiding and supporting seat and an elastic component; the guiding and supporting seat is fixed to the bottom plate and is provided with a non-circular cavity; the bottoms of the elastic component and the node supporting seat are arranged in the non-circular cavity; the outer contour of thenode supporting seat is matched with the non-circular cavity; a non-circular groove matched with a swing bolster node is formed in the top of the node supporting seat; and the outer contour of the topof the node supporting seat is matched with a swing bolster arm hole for installing the swing bolster node. According to the swing bolster node positioning and press-fitting device and press-fittingmethod, the top of the node supporting seat can be completely matched with the contour of the end of the swing bolster node by finish machining, so that in the press-fitting process of the swing bolster node, the phase position between the swing bolster node and the swing bolster node positioning and press-fitting device is fixed, and the problem of phase change of the swing bolster node in the press-fit process is effectively overcome.

Description

technical field [0001] The invention relates to the technical field of maglev trains, in particular to a bolster node positioning and pressing device and a pressing method. Background technique [0002] At present, high-speed maglev trains use bolster structures for support. A bolster consists of two bolster arms, which are divided into left bolster arms and right bolster arms. Because the bolster components need to cooperate with the beam frame during assembly, Therefore, when the bolster node is pressed onto the bolster arm, there is a strict phase relationship between the bolster node and the bolster arm, so that the assembly of the entire bolster is satisfied. [0003] At present, the bolster node is generally press-fitted to the bolster arm directly by using a press-fitting device. During the press-fitting process, the phase between the bolster node and the bolster arm is easy to change, and the press-fitting accuracy of the bolster node is not high. Contents of the i...
