Description
Technical field
The present invention relates to the technological equipment and method of a kind of assembling of thin-walled tube assembly, especially a kind of thin-walled tube assembly is spacing
Press-loading process is equipped and method.
Background technology
In modern automation control development field, servo valve belongs to one of the core product in the field.The function of servo valve
It is that the current signal of input is converted into mechanical signal, is finally exported with the hydraulic pressure signal for amplifying.Torque-motor（Hereinafter referred to as horse
Reach）It is the main building block of servo valve, belongs to first order switching mechanism, is also the core of servo valve.Its function is by input
Current signal is converted into magnetic field signal, and mechanical output is converted into by magnetic field signal, referred to as electric --- magnetic --- machine transfer process.
Magnetic in motor part structure --- machine transfer process is designed with a piece number for key --- valve seat armature component
（Hereinafter referred to as component one）, its process for realizing function is：Armature longitudinal direction both sides in component secure coil block life up and down
Into the magnetic line of force, while the magnetic conductor up and down for being designed with high magnetic permeability and low-coercivity is located at up and down, there is magnetic longitudinal both sides of armature
Steel strengthens magnetic field intensity.When the electric current for being input into two groups of coils changes the magnetic field of alternation, the lengthwise position of armature of will surviving
Produced with the change in magnetic field and waved, due to the internal diameter 3 of bourdon tube（The unit of following Arabic numerals is all millimeter）, baffle plate
Minor diameter 2.5, so also being swung therewith with the baffle plate of armature tight fit.The thin-walled position of bourdon tube then produces bending simultaneously
Deformation produces reaction force, when the reaction force that input current change eliminates bourdon tube promotes baffle plate to recover middle position（That is armature
Reset）.

The both sides of fixed block are respectively provided with a screw corresponding with the 6.2mm holes of valve seat, by the spacing valve seat of clamping screw in screw
The direction of the planes of baffle plate top thickness 1.5mm two of attitude and adjustment armature component；The spacing briquetting is by two symmetric body groups
Into two symmetric bodies are fastened together with two screws, for clamping armature component, the center of two symmetric body binding faces of spacing briquetting
Position is provided with stepped hole, and pressure head is connected with spacing briquetting, for keeping water to spacing briquetting transmission pressure, the spacing briquetting of balance
It is flat.
Between having 0.1mm between the thin-walled diameter of the stepped hole in spacing briquetting, wherein aperture and armature component bourdon tube
Gap, during assembling thin-walled tube assembly, the step that aperture is used to clamp between the thin-walled diameter position of armature component bourdon tube, big aperture falls
On the step of cylindrical of actual arrival bourdon tube size.
A kind of spacing press-loading process method of thin-walled tube assembly, its step is：Implement the assembling of valve seat armature component first, will
Valve seat is put into the die cavity of fixed block, and the position for limiting valve seat is adjusted with clamping screw；Spacing briquetting is divided into two valves, by armature
After the bourdon tube thin-walled position clamping wherein of component, spacing briquetting is fastened together with screw；By the baffle plate of bourdon tube lower end
Two planar ends of thick 1.5mm are stretched into the center stepped hole of valve seat down；When the cylindrical contacts of bourdon tube 4.7mm of armature component
During to valve seat 4.7mm holes, met the requirements by two in-planes of thickness 1.5mm at the top of two clamping screw regulating fenders；Move down pressure
The backward spacing briquetting transmission pressure of level of the spacing briquetting of head adjustment is until the lower plane of spacing briquetting is close to valve seat upper surface；So
After lift pressure head, the spacing briquetting of righting, screw out two clamping screws, unclamp spacing briquetting, valve seat rank is finally taken out from fixed block
Iron component, press-fits end.
Beneficial effects of the present invention：
The packaging technology of valve seat armature component is practical, effective, reliable, and the tool structure of use is simple and direct, and the manufacturing cycle is short, into
This is low.Valve seat armature component after assembling meets design requirement.
Servo valve belongs to the product of high, precision and frontier, and high-tech area is widely used, and with high content of technology, value is expensive.Servo
The function of valve is mainly made up of two-stage, the signal conversion and the power amplification of the second level of the first order, and power amplification can be set several again
Level is amplified, so that servo valve can control power output up to tens, executing agency that is up to a hundred, even going up kiloton.Valve seat armature component
Function " magnetic --- machinery " is the important ring in motor " electric --- magnetic --- machinery " transfer process, and " magnetic --- machinery "
The component and part quality of conversion links are higher than other components and part of servo valve to the sensitivity of technique and management, such as
The semi-finished product of magnetically soft alloy are particularly severe to the requirement for managing, it is impossible to collide with, clash into and implement machining.So valve seat is held in the mouth
There are 3 kinds of key items for listing the work such as technique, management in the assembling of iron component and the 4 of component kinds of parts." magnetic --- machine
Tool " translation function stabilization, is that the function-stable of motor is laid a good foundation.
Assembling technique of the invention is simple to operate, clear, convenient, easily grasp.
