Coil winding machine linkage section is used to be connected with coil winding machine, which is provided with the company's machine positioning baffle positioned at its inner, determines
Position pin and locating groove；The material that existing winding fixture is typically adopted is for Cr12 mould steel.
The major defect that existing winding fixture is present is：1. skeletal support Duan Weiyu square tube shapes coil rack shape
The section configuration of shape matching is the cuboid of rounded square, and cuboid four sides is plane, due to each face
Plane is, whole face contact, contact area are big when filling, taking skeleton, and frictional force is big, especially after coiling
Coil is tensioned, causes operation laborious, and winding fixture abrasion is big fragile.Additionally, being also unfavorable for
Mitigate winding fixture weight.2. width≤the 1mm of escape, narrow, and such skeleton is inserted into skeleton
The laminating of support Duan Houyu coils baffle plate not closely, there is gap, and each wire casing and coiling that can cause skeleton has position
Error, coiling is irregular, and play can occur when skeleton rotates coiling, directly affects around line mass.3.
Made using Cr12 mould steel, although this steel intensity is high, have preferable quenching degree and good wear-resisting
Property, but poor impact toughness, and be processed according to quenching technical, quenching technical can because of technique, set
Standby, operational error and produce overheated, oxidation, decarburization, deformation, cracking, hardness deficiency, soft spots etc. lack
Fall into.Especially Cr12 mould steel is than great, cost height, therefore also makes whole winding fixture weight big, coiling
Shi Rongyi produces bias, and manufacturing cost is high.
According to problem above, how to be improved on existing winding fixture architecture basics, mitigate weight,
Friction is reduced, is easy to fill, taken skeleton operation, realize that skeleton laminating is tight, improve around line mass and reduce system
Cause originally to become industry concerned issue.
The content of the invention

The escape of frame positioning baffle and the positioning ball of locking skeleton, on the coil winding machine linkage section position is provided with
Company's machine positioning baffle, alignment pin and the installation draw-in groove held in the inner；It is characterized in that positive four side of the fillet
Each side middle part of shape is an inner concave curve.
The withdrawing well width of the skeletal support section is 2-3mm.
The material of the winding fixture is aluminium alloy, and is provided with horniness anode oxide film on its surface.
The material of the winding fixture is AL7075 aluminium alloys, and the thickness of the horniness anode oxide film is
50-80um。
Borehole is provided with the skeletal support section.
The invention has the beneficial effects as follows：1. due to provide winding fixture skeletal support section four sides vertically
Middle part be provided with lower cancave cambered surface, can farthest reduce the contact area of skeletal support section and skeleton,
So as to significantly reduce frictional force, it is convenient time saving and energy saving to plug when filling, taking skeleton, and prevents coiling from controlling
Tool abrasion, while also making winding fixture weight saving.2. the escape of skeletal support section is widened to 2-3mm,
Skeleton is brought into close contact with coil baffle plate, realize each wire casing and coiling accurate contraposition of skeleton, eliminate
Site error, coiling is regular in order, and avoids skeleton that play occurs when rotating coiling, it is ensured that around line mass.
3. the material of winding fixture adopts aluminium alloy, and preferred AL7075 aluminium alloys, proportion is little, with existing Cr12
Mould steel is provided with horniness anode oxide film than more significant mitigation winding fixture weight on its surface, improves
Wearability, surface is smooth, it is easy to which skeleton is plugged, and prevents winding fixture from wearing and tearing.4. in skeletal support section
Be provided with borehole, equally play a part of to reduce winding fixture weight, the mitigation of weight make winding fixture around
Bias is difficult during line, it is ensured that around line mass.Jing production practices show, the winding fixture that the present invention is provided with
Existing winding fixture compares before improving, and skeleton is reduced to original with the contact area of skeletal support section
10-20%, the weight of whole winding fixture is reduced to original less than 26%.Improve simple operation and generation
Significant energy-saving material-saving effect.
