Low floor bogie rotating arm node press mounting device

Abstract

The invention discloses a low floor bogie rotating arm node press mounting device, which comprises a square pin which runs through a through hole node and can penetrate into a blind hole node, wherein a front positioning block which is used to fix the vertical position of the square pin is arranged between the blind hole node and the through hole node, a press mounting pressure head is arranged on the bottom end of a blind hole of a rotating arm, and is provided with a hydraulic cylinder, a rear positioning block is arranged on the hydraulic cylinder, and the rear and the front positioning blocks are connected through a plurality of tooling connecting rods. The low floor bogie rotating arm node press mounting device is a mechanical device which is designed by analyzing structures of products and can achieve a press mounting mode, utilizes launch force of a piston rod of the hydraulic cylinder to pull connecting rods, and the forced connecting rods transmit acting force onto nodes through the front positioning block, and enable the nodes and node holes to relatively move and to be pressed.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a low-floor bogie pivot arm node press-fitting device. Background technique [0002] The bogie jib node is an elastic body composed of rubber and metal. Its main function is to ensure the positioning between the bogie frame and the wheel set, and to ensure the longitudinal, lateral, deflection and torsional rigidity required for the bogie's running stability. , while transmitting the traction and braking forces from the wheelset to the frame, and bear the longitudinal and lateral forces between the wheelset and the frame. [0003] At present, the blind hole joints of the low-floor bogie jib are press-fitted by manpower hammering. Disadvantages of this press-fitting method: During the hammering process, the point of action of the hammering force is not necessarily at the center of the parts, so that there is a lateral force component between the parts, causing the parts to ...

AI Technical Summary

Problems solved by technology

Disadvantages of this press-fitting method: During the hammering process, the point of action of the hammering force is not necessarily at the center of the parts, so that there is a lateral force component between the parts, causing the parts to be pressed in obliquely, which will cause damage to the assembly surface and damage the parts ; At the same time, hammering consumes a lot of manpower, and there are serious safety hazards, which is not conducive to occupational health
