Description
Technical field
The present invention relates to starter technical fields more particularly to a kind of high-power starter stator coil to draw soft whipping wire company
Connect technique.
Background technology
Generator lead-out wire is in addition to carrying its own gravity load, and when generator is run, lead-out wire is also subject to strong shake
Dynamic loading, it is more demanding to the weld strength of weld.When welding, welding counterbore base temperature is not easy to control, preset silver soldering piece
The defects of easily there is uneven heating, causing not merge, is lack of penetration, preset silver soldering piece by it is solid state transformed be liquid when shrinking percentage compared with
Height, the defects of being also easy to produce stomata.
Driving motor has winding stator core neutral point and three-phase lead-out wire generally to use flame silver acetylide copper welding procedure
Or cold-extrusion technology, flame silver acetylide copper welding procedure have the following disadvantages：1, of high cost, when welding required silver-copper brazing alloy,
About 3500 yuan/kg of price, bus motor every dosage about 0.1~0.15kg, in the welding process also aerobic gas, acetylene, help weldering
The auxiliary material that disappears such as agent, silver-bearing copper welding material cost are higher；2, it takes a lot of work, flame silver acetylide brazing, which connects, is not suitable with pipelining, raw
It is low to produce efficiency, it is dangerous, not environmentally；3, of poor quality；4, shape is unsightly.
Driving motor is following not with the presence of cold-extrusion technology used by winding stator core neutral point and three-phase lead-out wire
Foot：Winding quality of connection is poor, and winding leading-out wire connection is unreliable, and there are virtual connections phenomenons, and contact resistance is big, and temperature increases；It is easy
There is three-phase dc resistance unbalance, to influence motor performance
In recent years, more and more people begin to use automobile, China's car ownership to be substantially increased, in order to meet people's
Use demand, a large amount of automobile manufacturing company and auto-parts supplier are badly in need of improving the manufacture work of automobile and its spare and accessory parts
Skill, and automobile starter is as an important spare and accessory parts in automobile, the firmness of assembly directly affects automobile
Service life, therefore the stator coil in starter assembling process is drawn soft whipping wire Joining Technology and is increasingly received significant attention.
Such as Chinese patent " 105478989 A of CN " discloses a kind of Welder of air inner-cooled turbogenerator lead-out wire
Skill, the lead-out wire include connecting circular tube and the upper binding head and lower union joint that are welded with connecting circular tube both ends, it is characterized in that：Weldering
Two Intermediate Frequency Induction Heating Equipment different capacities are used when connecing while being heated, and to connecting circular tube and upper binding head and lower connection
Circumference brazed seam between head carries out manual filler.The technical solution that the welding procedure uses is sets using two Frequency Induction Heatings
Filler is carried out to brazed seam by hand while spare different capacity heats simultaneously, it is not right that this welding method is easy to cause both sides welding
Claim, is susceptible to weld crack.
In another example Chinese patent " 103447706 A of CN " discloses driving motor of electric vehicle winding neutral point and extraction
Wire-bonding technique, it is characterised in that：It includes the following steps：S1, removal draw the insulated paint of thread end, whole by thread end is drawn
Manage it is bundled, with copper sheet package tighten extraction thread end；S2, the voltage for adjusting bonding machine are 20~25V；S3, using bonding machine wink
Between welding winding neutral point and three-phase pinout connector, weld interval is 3~6 seconds, winding neutral point and lead-out wire fusion welds
It is integrated；S4, welding quality is checked, it is qualified.The patent draws thread end the technical solution adopted is that being wrapped up with copper sheet, so
Copper sheet is welded on winding neutral point afterwards, the connection of lead-out wire and winding neutral point is realized with this, but the program exists very much
Problem：By package power connection between lead-out wire and copper sheet, connection is insecure, is easy to fall off；Lead-out wire arrangement is insecure, is easy
Loosely.
Invention content
To overcome the problems, such as that welding existing in the prior art is asymmetric, easily cracked, lead-out wire connection is unstable, this
Invention provides a kind of high-power starter stator coil extraction soft whipping wire Joining Technology, which is characterized in that including following step
