What this utility model was realized in：
A kind of semiaxis fraising mould, it includes ream die shoe plate and fraising template, the fraising die shoe plate and the template that reams
Between form semiaxis ring flange clamping space, it is fixed that bottom and the semiaxis ring flange seam gap of the template that reams cooperatively form seam
Position；Semiaxis ring flange reverse side develops the benchmark to form half shaft flange reverse side with fraising die shoe plate concave surface；Fraising template is by positioning
Pin is with any one flange hole of semiaxis ring flange to cooperatively forming flange Internal hole positioning.
Further, the fraising template periphery is provided with the guide hole of half shaft flange fraising, fraising die shoe plate concave surface periphery correspondence
The resigning hole of half shaft flange fraising is provided with, the guide hole of half shaft flange fraising is connected with hinge sleeve by bushing, and hinge sleeve is by compressing spiral shell
Nail is fixed in fraising template.
Further, hinge sleeve to form flange endoporus calmly to being connected with any one flange hole of semiaxis ring flange by alignment pin
Position；After removing alignment pin, hinge sleeve is coordinated with reamer gap, and hinge sleeve is oriented to reamer, while hinge sleeve is limited to reamer horizontal direction.
Further, the bottom of the fraising template is provided with half shaft flange fraising chip area.
Further, with the contact area of drill jig supporting plate concave surface, half shaft flange reverse side ensures that, more than 95%, alignment pin is in method
During blue Internal hole positioning, alignment pin is ensured more than 70% with the contact surface of fraising template and semiaxis flange hole.
This utility model alignment pin, semiaxis seam and concave surface form " two pin one sides " location structure, locating and machining benchmark with
Element Design benchmark is consistent, the position error for not having a Reference misalignment and producing, due to mould locating and machining benchmark and the semiaxis of reaming
Reference for assembling is consistent, assembles later half shaft flange hole location within technical requirements, and the flange hole location of final products is by cutting with scissors
Casement ensures.

Specific embodiment
This utility model can be made to this utility model into the-description that walks, however, this practicality by the following examples
New scope is not limited to following embodiments.
Embodiment 1：
By the die shoe plate 1 that reams, ream a kind of semiaxis fraising mould template 2, bushing 3, hinge sleeve 4, housing screw 5, alignment pin 6
Composition, between fraising die shoe plate 1 and fraising template 2, fraising template 2 is coordinated semiaxis ring flange clamping with semiaxis seam gap,
So as to realize that seam is positioned；Semiaxis ring flange reverse side is developed with 1 concave surface of fraising die shoe plate, so as to realize with half shaft flange reverse side being
Benchmark；Fraising template 2, is realized to cooperation with flange Internal hole positioning by alignment pin 6 and any one flange hole of semiaxis；To sum up institute
State, the processing mode is " two pin one sides " positioning i.e. alignment pin 6, semiaxis seam and concave surface, and two sell one side limits 5 freedom
Degree, is left the degree of freedom of Z-direction, after alignment pin 6 is thrown into, fixes drill jig with startup hold down gag, now 6 freedom of semiaxis
Degree is restrained.
Fraising template 2 and 3 interference fit of bushing, bushing 3 are coordinated with 4 gap of hinge sleeve, and hinge sleeve 4 is fixed by housing screw 5,
Hinge sleeve is coordinated with reamer gap, and hinge sleeve plays a part of to be oriented to, while hinge sleeve fixes the position of reamer horizontal direction, so as to ensure half
The position degree of method of principal axes flange aperture, circularity.
Fraising template 1 processes chip area on milling machine, it is easy to which iron filings are discharged.
Fraising template 2 should ensure that more than 80% with the contact area of semiaxis seam, half shaft flange reverse side and drill jig supporting plate
Contact area ensure that more than 95% alignment pin 6 is ensured more than 70% with fraising template 2, the contact surface of semiaxis flange hole.
By taking certain vehicle rear axle shaft as an example, as shown in Figure 2,3, six holes are uniformly distributed, and reference circle isFlange excircle
It is a diameter ofFlange hole location is 0.2, and flange hole is a diameter ofSemiaxis ring flange clamping is in 1 He of fraising die shoe plate
Between fraising template 2, fraising 2 diameter of bore of template isSemiaxis seam external diameter isTherefore in fraising template 2
Hole is coordinated with the non-gap of semiaxis seam, so as to realize that a seam is positioned；1 concave surface external diameter of fraising die shoe plate isIt is easy to semiaxis
Quick to position, semiaxis ring flange is cylindrical to be developed with 1 concave surface of fraising die shoe plate, the contact area of half shaft flange reverse side and drill jig supporting plate
Ensure more than 95%, so as to realize on the basis of half shaft flange reverse side；Fraising template 2 is any one with semiaxis by alignment pin 6
Individual flange hole to cooperation, alignment pin under the percussion power of hand hammer with semiaxis flange hole interference fit, alignment pin 6 and fraising template 2,
The contact surface of semiaxis flange hole ensures more than 70%, realizes with flange Internal hole positioning.
Fraising 2 uniform bore dia of template be3 external diameter of bushing isFraising 2 equal cloth hole of template and bushing 3
For interference fit, 3 diameter of bore of bushing is4 external diameter of hinge sleeve isTherefore 3 endoporus of bushing is gap with hinge sleeve 4
Coordinate, hinge sleeve 4 is fixed by housing screw 5, hinge sleeve internal diameterReamer is a diameter ofTherefore between hinge sleeve and reamer are
Gap coordinates, and hinge sleeve plays a part of to be oriented to, while hinge sleeve fixes the position of reamer horizontal direction, so as to ensure the position of semiaxis flange hole
Degree of putting, circularity.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model
