The compression bonding apparatus of intrusion.
Background technology
High-speed railway（Hereinafter referred to as high ferro）Due to speed is fast, efficiency high, energy-conserving and environment-protective, safety and comfort etc. it is many excellent
Point, it has also become the important directions of track traffic development.Especially nearly ten years, with economic and society fast development, China is high
Iron has obtained great-leap-forward development, and has driven world's high ferro upsurge in construction of a new round.By in September, 2016, Chinese high ferro fortune
Battalion's total kilometrage has broken through 20000km, builds high ferro operation network the biggest in the world.But as high ferro runs the continuous increasing of the time limit
Long, the contact net failure caused by the fatigue failure of high ferro contact network key parts happens occasionally, and has a strong impact on high ferro
Operation safety.
Wherein, dropper is one of key components and parts in contact net system, according to military wide company feedback, is runed 7 years, hundred kilometers
Dropper ruptures tens.It was initially believed that the reason for causing this phenomenon is fatigue damage and stretches bow pressure.Feed back according to All other routes, hang
String occurs that breakage problem is extremely more with respect to for other parts, but experimental study of the inspection point to dropper all proves which is qualified.From
From the point of view of survey, 90% people thinks that dropper line loss wound is to be bent while clamper tube crimp force repeatedly due to which in working order
Improper initiation fatigue clear break.
For at present clamper tube compression bonding method it is more traditional, directly crimped by clamper tube pressing tongs, can neither be right
Crimp force size is controlled (different workers processings are different to the crimp force that clamper tube applies)；Cannot guarantee that intrusion
（Different workmans' is different to time for being reinforced to clamper tube using Press Plier, causes clamper tube deformation quantity different）, finally lead
Cause the last crimping error of clamper tube larger, the reliability of clamper tube is reduced.
The content of the invention
Present invention aims to the deficiencies in the prior art, there is provided a kind of precise control railway Pantograph-OCS system dropper pressure
Enter the compression bonding apparatus of amount, to solve the problems, such as that traditional clamper tube crimp force size and intrusion accurately can not be controlled.
To reach above-mentioned purpose, the present invention is adopted the technical scheme that：
A kind of compression bonding apparatus of precise control railway Pantograph-OCS system dropper intrusion are provided, which includes load maintainer；
Load maintainer includes loading leading screw；Loading leading screw is threadedly coupled with front apron and bearing holder (housing, cover) successively；Bearing holder (housing, cover) is embedded in and pushes away
One end of power bearing, the other end and the bearing rod interference fit of thrust bearing；Bearing rod passes through linear bearing and semi-open type straight line
Bearing, its end are coordinated with dynamic pressure play movement；A static pressure inlet is fixed with to dynamic pressure joint just, dynamic pressure joint and static pressure connect
The aluminium hydraulic pressed connecting pipe of fixed dropper is placed between head；
A magnetic stripe plate for being pasted with magnetic stripe is fixed with bearing rod, is fixed with pedestal and is coordinated, hangs for collection with the magnetic stripe
The grating rule displacement sensor of string intrusion.
Preferably, the grating scale displacement sensor bracket for carrying grating rule displacement sensor is fixed with pedestal.
Preferably, the balancing pole that control magnetic stripe plate is rocked is fixed with magnetic stripe plate.
Preferably, static pressure inlet is connected with pressure sensor by static pressure inlet seat.
Preferably, linear bearing is fixed on linear bearing cushion block, and semi-open type linear bearing is fixed on semi-open type linear axis
On rim block.
Preferably, pedestal head and end fixes front apron and backboard respectively；It is fixed straight successively between front apron and backboard

Preferably, front apron, linear bearing cushion block, semi-open type linear bearing cushion block and backboard are centrally located at always
On line.
The compression bonding apparatus of the precise control railway Pantograph-OCS system dropper intrusion that the present invention is provided, with following beneficial effect
Really：
Dynamic pressure connector end is fixed with static pressure inlet, and aluminium hydraulic pressed connecting pipe is placed between dynamic pressure joint and static pressure inlet, in aluminium hydraulic pressed connecting pipe
Fixed dropper, static pressure inlet transmits the force to pressure sensor by static pressure inlet seat, and the motion of bearing rod is with moving magnet
Motion, meanwhile, grating rule displacement sensor collection displacement data, so as to detect dropper intrusion.
By need crimping dropper be installed in aluminium hydraulic pressed connecting pipe, rotary screw, promote dynamic pressure joint along rectangle gathering sill to
Front movement so that dynamic pressure joint just touches aluminium hydraulic pressed connecting pipe, now pressure sensor will have the change of registration, while writing down grating
The initial value of rule displacement sensor, then proceeding to applying pressure makes aluminium hydraulic pressed connecting pipe produce deformation, so as to play a part of to fasten dropper,
Simultaneously the crimp force and intrusion according to needed for dropper is controlling entirely to crimp process.During crimping, grating scale displacement
Sensor and pressure sensor are sent to the data of collection in data acquisition control system, and data acquisition control system is received simultaneously
The data that analysis is collected, and by data feedback to workmen, workmen implements crimping according to the data of feedback, it is ensured that right
Dropper implements accurate crimp force and intrusion, so as to improve the work quality of dropper, extends the service life of dropper.
