Description
Technical field
The present invention relates to motor component manufacturing technology field, a kind of positioning compression work making electric machine iron core
Dress.
Background technology
At present, at electric machine iron core manufacture view, generally use and will solidify with machinery after the punching superposition of some stamping-out molding
Method for shaping, the more commonly used has the folded method of welding, button and sleeving and riveting method three kinds.Wherein: welding refers to outer circumferential edge along upper pre-
With argon tungsten-arc welding, bumps melt is constituted the method solidification of weld seam calmly after being provided with the punching superposition of triangle or circular salient point
Type；Detain folded method to refer on same position, not only be provided with button hole but also be provided with the method for the punching superposition fastening that button is filled in admittedly by every
Chemical conversion type；Sleeving and riveting method refers to put into positioning tool after dimpled punching superposition interlocks compress setting on every with lamination fastener of motor
After with sleeving and riveting all-in-one-piece method solidifying and setting.The feature that three is respectively provided with technical maturity, easy to operate and cost of manufacture is low, all
It is only applicable to make common relatively simple for structure, punching is relatively thin, volume is relatively small iron core, and owing to technique is each
Different, cause production cost higher；Additionally, due to these manufacture methods are respectively provided with the characteristic of partial points position mechanical consolidation sizing,
The quality of produced iron core is easily restricted by gap and uniformity between punching thickness, thrust size, sheet, and due to iron core forming
Because being under the mechanical fasteners state of local point of accumulation, self stress is in uneven state all the time in rear punching, thus impact from
The flatness of body, makes the basic configuration off-design requirement of iron core, and gap inequality, bore area and outer surface between punching occur
Perpendicularity and integral surface flatness is undesirable, even result in generation electric machine iron core cracking, punching local upwarps deformation etc. and pays no attention to
Think situation, and then affect the electromagnetism electric property of electric machine iron core, finished product rate, quality stability and functional reliability, so,
Consider all to owe ideal from practicality and economy point.
Summary of the invention
The invention aims to overcome current undesirable situation existing in terms of electric machine iron core making, it is provided that a kind of
Be conducive to that punching fast and reliable superposition is spacing, balance compress and can ensure that under iron core solidifying and setting state punching stress uniformly,
Clearance constant between punching, the location pressure of core configuration dimensional accuracy, electromagnetism electric property and Mechanical Strength Design requirement can be met
Tight frock.
The positioning compression frock making electric machine iron core of the present invention, consists predominantly of lower shoe, top board and is arranged on down
Limit component between base plate and top board and securing member, be characterised by: during described limit component has including in punching
The interstitial hole coupling of central hole and periphery hole is stretched and is put spacing function, cross section in being consistent with the center hole shape size in punching
The lateral opening positive stop strip that mandrel is consistent with the periphery hole geomery in punching with cross section is constituted；Described securing member is by consolidating of matching
Fixed pattern screw rod and rotatable swivel nut are constituted；The central shaft peace corresponding with the centre bore in punching it is provided with on described lower shoe
Dress hole arranges the corresponding lateral opening positive stop strip providing holes in position and fixed screw rod installing hole with the periphery hole in punching；Described
It is provided with on top board to stretch with the central shaft installing hole on lower shoe, lateral opening positive stop strip respectively and puts hole and fixed screw rod installing hole
Corresponding central shaft spacing hole, lateral opening positive stop strip are stretched and are put hole and rotatable swivel nut insertion hole；In a state of use, described consolidate
Fixed pattern screw rod is fixedly installed on the fixed screw rod installing hole of lower shoe, and central shaft and the activity respectively of lateral opening positive stop strip are stretched and put
On the central shaft installing hole of lower shoe and lateral opening positive stop strip providing holes, described punching is by described central shaft lateral opening positive stop strip limit
On position, the sheathed lower shoe of superposition, and swivel nut spacing by top board pressure holding, rotatable and fixed screw rod are to stubborn compacting-shaping, structure
Become punching to align and be in the iron core of reliably shaping compressing spacing state；Described is in the ferrum of reliably shaping compressing spacing state
Core, constitutes to be in after withdrawing goes out lateral opening positive stop strip and central shaft and compresses the ferrum of reliably shaping that the surfaces externally and internally of spacing state is exposed
Core；On the surfaces externally and internally that described reliable sizing iron core is exposed uniform application have heat after the high intensity of reliable solidification function
Binding agent and constitute after hot setting is shaped punching stress uniformly, clearance constant between punching, can ensure that and meet core configuration chi
The making electric machine iron core that very little precision, electromagnetism electric property and Mechanical Strength Design require.
The present invention based on above-mentioned design makes the positioning compression frock of electric machine iron core, due to the centre bore in punching and
Periphery hole be rely on arrange, the limit component that reliably supported by lower shoe and top board, can from level to, vertical to spacing, and
Synchronize pressure punching to iron core nominal thickness down by regulation securing member and constitute the iron core of preliminary sizing, and unload lower limit on this basis
Position component, be more uniformly coated with on iron core surfaces externally and internally with the high-strength structureal adhesives that will not deform or ftracture after there is hot setting,
After making sizing and solidifying, iron core sizing is reliable, can fully meet the solid shape size of Structural Design Requirement, constant punching gap
With reliable mechanical strength, not only can ensure that the electromagnetism electric property that iron core is stable, and due to punching stress uniformly, between punching
In conjunction with reliable, can stop iron core cracking, punching in prior art warp etc. affect the situation such as product quality and working life
Raw, thus the positioning compression frock making electric machine iron core of the present invention substantially has rational in infrastructure and science, easy to operate and one-tenth
This is the lowest, conforming product rate is high, works widely applicable, if reasonably arrange the limit component adapted with interstitial hole in punching and
The securing member adapted with iron core thickness, just can meet difformity, the punching of thickness make high accuracy size iron core requirement,
There is the strongest practicality.
