A rail vehicle pivoting arm type axle box positioning node assembly device

Abstract

The invention relates to a railway vehicle jib-type axle box locating node assembling device. The railway vehicle jib-type axle box locating node assembling device comprises an axle box body, a locating node, a gland and bolts, and further comprises a press-fitting platform, a first abutting device and a second abutting device. The axle box body, the locating node, the first abutting device and the second abutting device are fixed onto the press-fitting platform, the first abutting device abuts against the gland from one side to enable the gland to abut against the end portion of the axle box body and the second abutting device abuts against the axle box body to provide back pressure when the axle box body is pressed onto the locating node. The railway vehicle jib-type axle box locating node assembling device is simple and convenient to operate and high in universality, effectively lowers the labor intensity for motor train unit jib-type axle box locating node assembling, improves the production efficiency and meanwhile guarantees the assembling quality.

Description

technical field [0001] The invention relates to a connection device between a rail vehicle axle box and a frame, in particular to a rail vehicle pivoting arm type axle box positioning node assembly device, which belongs to the technical field of rail transportation. Background technique [0002] On the EMU, a new type of pivoting arm axle box is adopted. One end of the pivoting arm axle box is connected with the pivoting arm seat on the frame through a rubber positioning node. Buffer and displacement in the direction and circumferential direction. [0003] Such as figure 1 As shown, the positioning node 1 is installed on the axle box 4 through the gland 2 and four bolts 3. During the installation of the positioning node 1, the bolts 3 need to overcome the rebound force of about 2000N. If manual work is used, the labor intensity of the operators will be high. , because the positioning node 1 is made of rubber and has elastic characteristics, it is impossible to ensure that ...

Problems solved by technology

[0003] like figure 1 As shown, the positioning node 1 is installed on the axle box 4 through the gland 2 and four bolts 3. During the installation of the positioning node 1, the bolts 3 need to overcome the rebound force of about 2000N. If manual work is used, the labor intensity of the operators will be high. , since the positioning node 1 is made of rubber material and has elastic characteristics, it is impossible to ensure that the four bolts 3 that fix the gland 2 have similar fastening forces, which may easily cause the positioning node 1 to be installed incorrectly, resulting in the failure of the positioning node 1 function
