Description

Technical Field

[0001] The utility model relates to the technical field of rubber product production and manufacturing, in particular to a rubber node press-fitting device. Background Art

[0002] Rubber nodes are important connecting components between the traction motor and the frame of rail vehicles. They are widely used in urban rail vehicles such as subways and light rails, and high-speed trains. Rubber nodes have important functions such as transmitting the longitudinal force of traction or braking, ensuring the stable operation of the train and having good guiding capabilities.

[0003] However, there are some problems in the prior art: the traction motor on the rail train bogie is connected to the frame through a rubber node, and the rubber node is pressed into the hanging hole of the traction motor hanging wall by a press-fitting method. During the press-fitting process of the rubber node, there is no special tooling to ensure that the axis of the rubber node and the hanging hole remain axially horizontal. During the press-fitting process, the rubber node is prone to rotation, so that the rubber node cannot be accurately pressed into the hanging hole, and it needs to be repeatedly disassembled and re-pressed. The press-fitting efficiency is low and the labor intensity of the operator is high. Therefore, we propose a traction motor rubber node press-fitting error-proofing device. Utility Model Content

A limit block corresponding to the limit groove is fixedly installed at one end of the fixed plate, and the limit block is slidably connected in the limit groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Hang the holding rod horizontally above the hanging hole to be pressed, then insert the docking block at one end of the rubber node into the hanging hole, slide a set of clamping blocks to make the docking block at one end of the rubber node plug into the plug-in slot, and then slide another set of clamping blocks to make the docking block at the other end of the rubber node plug into the plug-in slot, so that the two sets of clamping blocks can fix and clamp the rubber node, and then adjust the horizontal state of the holding rod by observing the horizontal ruler on the upper surface of the holding rod, so as to facilitate the continuous adjustment of the angle of the holding rod during the pressing process, so that the rubber node will not deviate during the pressing process and can be accurately installed in the hanging hole;

The outer diameter of the clamp is larger than the inner diameter of the adjustment hole, so that the clamp is interference-fitted into the adjustment hole, so that the fixing plate and the holding rod are tightly connected. The two sets of fixing plates further strengthen the connection strength between the fixing rod and the holding rod. BRIEF DESCRIPTION OF THE DRAWINGS
