One transitional pore；
4), after the lower profile of core part machines, auxiliary mould is utilized to act on transitional pore and machined complete lower profile dress
Press from both sides described core part；Then the upper profile of core part is processed；
5), after the bilateral profile of core part machines, with precision jig boring machine, core is made in the transitional pore expansion of core part
The centre bore required on part, is finally completed the processing of whole core part.
Described processing method, the aperture of transitional pore is d, and the aperture of centre bore is B, d≤B/2.
Described processing method, step 4) in, described auxiliary mould includes mandrel main body and chuck；Described mandrel main body
One end is connected with lathe spindle, and the end face of the mandrel main body other end is profile, and the lower profile of described profile and core part is mutually
Joining, the center of mandrel main body other end end face has alignment pin, and described alignment pin is coaxial with mandrel main body；Described core zero
Part is arranged in alignment pin by endoporus is the most sheathed by transitional pore, chuck, and the lower profile of described core part passes through chuck
Pressuring action abut in the profile of mandrel main body.
Described processing method, described auxiliary mould also includes that binding nut, described binding nut are arranged in alignment pin；Institute
State binding nut and by acting on chuck, core part is clamped between chuck and profile.
Described processing method, the external diameter of described alignment pin matches with the aperture d in core part transition hole.
Described processing method, the external diameter of described mandrel main body is H, maximum outside diameter A, the 2A/3≤H ＜ A of core part.
The method have the advantages that processing method of the present invention is by utilizing auxiliary mould to rubber pattern dimorphism face flake type
Core is processed, and first processes the lower profile of core, then by the clamping of auxiliary mould location, the upper profile of processing core, lathe adds
After work completes, precision jig boring machine process endoporus, lathe lapping.The method efficiently solves conventional clamping difficulty, and processing is tired
Difficulty, the problems such as precision controlling is difficult, and cut scheme raising production efficiency by composite entity sheet.

Detailed description of the invention
The processing method of embodiment dimorphism face flake rubber pattern core
1) a lot of due to every series-produced part as Figure 1-5, the mode therefore using integrated piece to cut is processed, and unification is advised
The bar of lattice 100mm length, the wastest turning and endoporus；
2) then bar is carried out heat treatment: quench tempering 39-43HRC:
3), after heat treatment completes, the lower profile of turnery processing first core part 4, dimensioned puts in place；Due to core part
4 centre bore B=10mm, upper and lower bilateral profile transition position is all the angle faces of cusp transition, does not has plane, in order to be worked into
Position, the transitional pore at one φ 5mm of center system is used for positioning, and during the lower profile of processing, stays polished amount, polishes profile.First
After the lower profile of core part 4 processes, reserve the allowance of profile on this core part 4, block with amputation knife, then
The lower profile of the next core part 4 of processing, by that analogy；
4), after the lower profile of core part 4 machines, utilize auxiliary mould clamping first core part 4, make this core zero
The lower profile of part 4 abuts in the profile on auxiliary mould for location, then processes the upper profile of core part.It assists work
The structure of dress is as shown in 4 and 5, including mandrel main body 1 and chuck 2；One end of described mandrel main body 1 is with lathe spindle even

The center of other end end face has alignment pin 1.1, and described alignment pin 1.1 is coaxial with mandrel main body 1；Described core part 4
Being arranged in alignment pin 1.1 by endoporus is the most sheathed by transitional pore, chuck 2, the lower profile of described core part 4 is led to
The pressuring action crossing chuck 2 abuts in the profile of mandrel main body 1.Described auxiliary mould also includes binding nut 3, described folder
Jack panel 3 is arranged in alignment pin 1.1；Core part 4 is clamped in folder by acting on chuck 2 by described binding nut 3
Between set 2 and profile.The external diameter of described alignment pin 1.1 matches with the aperture d of core part 4 transitional pore.Described mandrel
The external diameter of main body 1 is H, maximum outside diameter A, the 2A/3≤H ＜ A of core part 4.Core part 4 and the dress of auxiliary mould
Join as shown in Figure 5.The left side clamping of auxiliary mould clamps core zero to the main shaft of lathe, right side chuck 2 and binding nut 3
Part, completes the processing of profile on core part and polishes.
5), after the bilateral profile of core machines, with the centre bore of precision jig boring machine expansion manufacturing mold core part to 10mm, stay
Polished amount, it is ensured that tolerance；
6) last turner polishing endoporus.
The processing method of this dimorphism face flake rubber pattern core, efficiently solves various problems mentioned above, will be the most thorny
Machining state simplify, and by the way of integrated piece is cut ensureing precisely, easy, improve product quality on the premise of promote
Production efficiency.
