Face needs to carry out polishing processing, and roughness requirements Ra2.0 is hereinafter, at present can only be by lathe process.Workpiece and work when processing
It is big to fill total quality, limitation lathe revolving speed cannot be too fast.In addition the knife bar of bore hole is too long, and poor rigidity is easy shake.Process rear axle
Bore face roughness is very poor, and probable ranges are in Ra4.5-Ra5.2 or so.The step of needing subsequent increase retrofit.
Summary of the invention
In order to solve the above-mentioned problems of the prior art, it is an object of that present invention to provide one kind to be used for automobile main reducer
The processing unit (plant) and its processing method of shell bearing hole, to realize that required roughness can be obtained in time processing.
A kind of processing unit (plant) for automobile main reducer shell bearing hole of the present invention, including be arranged on lathe
Live spindle and knife rest；The live spindle free end is equipped with a tooling, and the tooling makes the axis of shell for clamping shell
Bearing bore center is overlapped with the axle center of live spindle；The knife rest is equipped with an electrical grinding machine, the axle center of electrical grinding machine and live spindle
Axis parallel, the bistrique of electrical grinding machine extends to live spindle direction, and bistrique side and bearing internal surface of hole be tangential on it is same
Plane；The knife rest can be fed along live spindle axial translation.
A kind of processing unit (plant) for automobile main reducer shell bearing hole of the present invention, the advantage is that, shell
After being fixed by tooling, live spindle need to only export the velocity of rotation of very little.The relative displacement of high speed is provided by electrical grinding machine, and bistrique exists
Knife rest is fed under driving to bearing hole.Bistrique and bearing hole are tangent after contact, and contact surface will do it polishing processing.Since rotation is led
Axle rotary speed is lower, and the stability of shell is very good, compared with existing, can also be obtained using the milling tools of identical roughness
Than existing better roughness.Only need time processing that can reach Ra1.5.And can continuously be fed, it is any without dismantling
The processing of two bearing holes can be completed in component, and efficiency is very high.
Preferably, the tooling includes a substrate, and the substrate side is installed on live spindle free end, and the other end prolongs
Cantilever is stretched out, the cantilever is for clamping shell.A kind of specific tool structure is provided, under present inventive concept inspiration, ability
Field technique personnel are readily conceivable that other tooling implementation methods.
Preferably, the live spindle direction of rotation is identical as the direction of rotation of bistrique.Opposite rotary-grinding can make
Shell is slightly shaken, can minimal effect machining accuracy.And the jitter amplitude of shell can be effectively reduced in rotation in the same direction, obtains most
Good machining accuracy.The revolving speed of bistrique can be up to thousand rpms, and live spindle need to only export several or tens revolutions per minute
Clock, therefore identical steering polishing is completely achievable.
Preferably, the bistrique is detachable bistrique.Can be according to different accuracy demand, replacement at any time is different coarse
The bistrique of degree is suitble to the shell of different model to use, more flexible.
A kind of processing method for automobile main reducer shell bearing hole designs processing unit (plant) as described above, utilizes
The tooling (21) clamps shell (10), makes shell (10) with the rotation of bearing hole (11) normal rotary shaft；Enable the electric mill
The bistrique (32) of machine (31) rotates, and bistrique (32) side is enabled to be in contact respectively with each bearing hole (11) inner surface.

Specific embodiment
As shown in Figure 1-3, a kind of processing unit (plant) for automobile main reducer shell bearing hole of the present invention includes
Live spindle 20 and knife rest 30 are set on lathe.20 free end of live spindle is equipped with a tooling 21, the tooling 21
For clamping shell 10, it is overlapped 11 center of bearing hole of shell 10 with the axle center of live spindle 20.The knife rest 30 is installed
There is an electrical grinding machine 31, the axle center of electrical grinding machine 31 and the axis parallel of live spindle 20, the bistrique 32 of electrical grinding machine 31 is to live spindle
20 directions extend, and 32 side of bistrique and 11 inner surface of bearing hole are tangential on same plane.The knife rest 30 can be led along rotation
The feed of 20 axial translation of axis.The tooling 21 includes a substrate, and the substrate side is installed on 20 free end of live spindle, separately
Cantilever is extended in one end, and the cantilever is for clamping shell 10.The rotation of live spindle 20 direction of rotation and bistrique 32
Direction is identical.The bistrique 32 is detachable bistrique.
A kind of processing unit (plant) and its processing method for automobile main reducer shell bearing hole of the present invention, work
Principle is, is first installed on tooling 21 on the free end of live spindle 20, and shell 10 is then installed on tooling 21, adjusts position
Setting is overlapped 11 center of bearing hole with the axle center of live spindle 20.Start the revolving speed that live spindle 20 exports tens rpms,
