Description
Technical field
The invention belongs to gear ring manufacturing fields, more particularly, to a kind of end tooth thin-walled gear ring vehicle sequence technique.
Background technique
As shown in Figure 1, the product is thin-walled end tooth gear ring, belong to typical thin-walled gear ring, thinnest part thickness only has 4.5mm.
The inner cavity of gear ring is formed with inner hole 1 and seam allowance 2, and interconnected inner hole 1 and seam allowance 2 are coaxially disposed, and 2 diameter of seam allowance is greater than interior
1 diameter of hole；Gear ring is first end face 3 in the end face close to 1 side of inner hole, and gear ring is second in the end face close to 2 side of seam allowance
End face 4；Gear ring outer circle 5 is transversely divided into the first cylinder 51 and the second cylinder 52, wherein the first cylinder 51 is located at 1 outside of inner hole,
Second cylinder 52 is located at 2 outside of seam allowance.
And existing vehicle sequence process is, after forging stock, successively carries out rough turn 5 end face of outer circle, rough turn interior hole end surface, half
Totally 5 sequences are processed for hole end surface, 5 end face seam allowance 2 of fine turning outer circle in 5 end face of fine turning outer circle, smart car.
But it because gradually reducing size, when causing last finishing processing, because of workpiece wall thickness, only 8.5mm, causes to clamp
Easily-deformable, and then circularity 0.025, the critical sizes such as diameter of bore 100% cannot be met the requirements.
Summary of the invention
In view of this, the present invention is directed to propose a kind of end tooth thin-walled gear ring vehicle sequence technique, exists to prevent not-go-end tooth thin-walled gear ring
It is deformed in last smart car.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of end tooth thin-walled gear ring vehicle sequence technique, comprising: rough turn process, using the first cylinder as clamping benchmark, to second
Cylinder, inner wall and second end face carry out the processing of big cutting output；Smart car inner hole process, the second cylinder processed with rough turn process
As clamping benchmark, inner hole and first end face are finished；Smart car seam allowance and outer circle process, the inner hole processed with smart car inner hole process

Further, the smart car inner hole process, the circularity of inner hole is within 0.025mm.
Further, the smart car seam allowance and outer circle process, using pull-up structure ringfeder after the more valve viscoses of high-precision, in tensioner
Simultaneously outer end face is connected on its positioning disk in hole.
Further, described before carrying out smart car inner hole process and smart car seam allowance and outer circle process, using the airtight inspection in end face
It surveys device and detects workpiece run-out tolerance.
Compared with the existing technology, end tooth thin-walled gear ring vehicle sequence technique of the present invention has the advantage that
(1) smart car process of the present invention, rough turn process have simplified original rough turn and half smart car sequence, are clamped workpiece
Wall thickness thicken, reduce deformation, while be changed in addition six sides clamping, make chucking power more evenly, be effectively ensured the second cylinder circle
Degree control can carry out the processing of big cutting output within 0.05mm.
(2) smart car inner hole process of the present invention, using the second cylinder that rough turn process is processed as clamping benchmark, because thick
The roundness control of the first cylinder by this sequence claw or after paying pawl finishing, is clamped in the outer physa within 0.05mm when turner sequence
In standard, grasping force control, can be to fasten workpiece, the workpiece for reaching big cutting output is indeformable, then under smaller pressure in 1.2Mpa
Inner hole and end face are finished, improves former inner hole circularity, stability contorting is within circularity 0.025mm.
(3) smart car seam allowance of the present invention and outer circle process, the inner hole of smart car inner hole process processing as tensioner benchmark,
It ensure that the concentricity and circularity of workpiece, while not changing the circularity and diameter of former inner hole.
(4) end face air tightness detection apparatus of the present invention effectively avoids reprocessing and scrapping caused by because of workpiece run-out tolerance.
