The frock making includes procedure below：Measurement needs to process the size of the part of aperture, and according to above-mentioned part
Size and structure fabrication special tooling；Frock is including the supporting surface for being supported to part, for entering to part basic circle
The keeper of row positioning；The unilateral fit clearance of frock and part basic circle in 0.02-0.06mm, by the supporting surface of frock come
Ensure that the flatness of part processing is less than 0.2mm；
The electrical discharge machining includes procedure below：
（1）By frock clamping in the C axle support plates of lathe；
（2）Calibration tool basic circle is less than 0.01mm with C shaft concentricities；
（3）Calibration tool benchmark straight flange is parallel with lathe X-axis, determines that lathe C axles rotation start angle is 0；
（4）Calibration tool supporting surface is less than 0.01mm with lathe B axle perpendicularity, and it is 0 to determine B axle；
（5）By standard correction X-axis of frock basic circle, Y-axis coordinate；
（6）Clamping compressing component ties the big plane of part less than 0.2mm；
（7）Call numerical control program to complete part by parameter card angularly to process.
The designing points of the present invention are, to Fixture Design so as to adjust selection of reference frame and the institute of special tooling and part
Cooperation between the datum hole of selection, just because of the cooperation that have selected between suitable benchmark and datum hole, so as to realize
Many angular aperture machining accuracies are high, enable the part hole tolerance to can guarantee that ± 0.05mm, the precision of integrated location reach ±
0.1mm。
Brief description of the drawings
Fig. 1 is anti-shock baffle modular construction schematic diagram in embodiment.
Fig. 2 is the structural representation of special tooling.
Wherein, reference is as follows：1- frock main bodys, the circular protrusions of 2- first, the circular protrusions of 3- second, 4- the 3rd
Circular protrusions, 5- supporting tables, 6- straight flanges.
Embodiment
It is an object of the invention to the defect for overcoming prior art, there is provided a kind of part based on spark erosion technique is many
The small hole forming method of angle, is described in further detail with reference to embodiment to the present invention.
Embodiment
Multi-angle hole processing is carried out to anti-shock baffle component as shown in Figure 1, processing method includes frock making
And electrical discharge machining.
Frock making measurement needs to process the size of the anti-shock baffle component of aperture, and according to above-mentioned anti-shock baffle
Size and structure fabrication special tooling；
As shown in Fig. 2 the special tooling being made includes frock main body 1, the frock main body is provided with supporting surface, basic circle
Indication piece, part keeper.
The part keeper includes two circular protrusions for being arranged on frock body upper surface, and respectively first is circular convex
Play 2 and second circular protrusions 3.The part keeper is used to be determined part installation site.
First circular protrusions, which are located in the middle part of frock main center, first circular protrusions, is additionally provided with through hole, is easy to
The concentric shafts of lathe are passed through.
The basic circle indication piece is also the circular protrusions for being arranged on frock body upper surface, is the 3rd circular protrusions.Institute
State the middle part of the 3rd circular protrusions 4 and also be provided with through hole, identified as basic circle.
In order to anti-shock baffle component matching, first circular protrusions, the second circular protrusions and the 3rd circular protrusions
The center of circle on the same line, frock main body is symmetrical on straight line where the raised center of circle in three centers of circle.
Frock body upper surface is additionally provided with the supporting surface of protrusion, and the supporting surface includes 6 supporting tables 5, for erosion control
Hit baffle plate assembly lower surface to be supported, 6 supporting tables are all rectangular parallelepiped structure.Above-mentioned 6 supporting tables are with frock main body
The center of circle centered on be uniformly distributed.The presence of supporting surface is supported to the uneven bottom of anti-shock baffle component, keeps erosion control
Hit parallel between baffle plate assembly upper surface and lathe X-axis.The frock body side is provided with straight flange 6, for being used as true edge.
Because the significance of the present embodiment is can be so that frock and unilateral the matching somebody with somebody of anti-shock baffle component basic circle
Gap is closed in 0.02-0.06mm, the flatness of part processing is less than 0.2mm, therefore every size of frock is highly important.
The external diameter of first circular protrusions is 77.1mm, and internal diameter is 40mm, is highly 15mm.
A diameter of 77.1mm of second circular protrusions, is highly 15mm.

The distance between the center of circle of first circular protrusions and center of circle of the second circular protrusions and described first circular convex
The distance between the center of circle risen and the center of circle of the 3rd circular protrusions are all 120.6mm.
Fixture between two supporting tables of arbitrary neighborhood is 60 °.
The length of any one supporting table is respectively 70mm, 12mm, 15mm.
Beeline between any one supporting table and the first circular protrusions center of circle is 85.388mm.The electrical spark working
Work includes procedure below：
（1）By above-mentioned frock clamping in the C axle support plates of lathe；
（2）Calibration tool basic circle is less than 0.01mm with C shaft concentricities；
（3）Calibration tool true edge is parallel with lathe X-axis, determines that lathe C axles rotation start angle is 0；
（4）Calibration tool supporting surface is less than 0.01mm with lathe B axle perpendicularity, and it is 0 to determine B axle；
（5）By standard correction X-axis of frock basic circle, Y-axis coordinate；
（6）Clamping compresses anti-shock baffle component and ties the big plane of part less than 0.2mm；
（7）Call numerical control program to complete part by parameter card angularly to process.
According to above-described embodiment, the present invention just can be realized well.What deserves to be explained is, before said structure design
Put, to solve same technical problem, some made in the present invention are used without substantial change or polishing
Technical scheme essence still as the present invention, therefore it should also be as within the scope of the present invention.
