Abstract
The invention discloses a hard turning process for auxiliary gearbox drive gears. The hard turning process mainly aims at machining the auxiliary gearbox drive gears which are complex in structure. The hard turning process is characterized by adopting the following machining steps of 1 tool fixture replacing, 2 positioning clamping and 3 finish turning. The hard turning process for the auxiliary gearbox drive gears has the advantages of being high in machining precision, high in machining efficiency and low in labor intensity.
Description
Technical field
The present invention relates to a kind of hard Vehicle Processing technique of odd-side drive gear；Mainly for baroque gear
Hard Vehicle Processing technique.
Background technology
Gear also becomes increasingly complex with the continuous expansion of application, structure.Existing many gears are in order to meet
The transmission demand of product, is required for carrying out the change in structure；Odd-side drive gear in such as automotive field
It is exactly a kind of baroque gear, the whole manufacture course of processing of this gear is very numerous and diverse, needs Jing
Cross more than ten procedures can just complete, and the hard turner skill of each end face is wherein processed due to positioning and this kind of gear
Center of gravity problem Jing often occurs processing situation not in place；Existing processing technique be all using grinding machine and lathe come
Shoulder face and cylindrical processing operation are carried out respectively, and cylindrical processing is carried out on grinding machine first, car is then recycled
Bed carries out the processing in shoulder face, is so accomplished by clamping school team twice, is easy to during clamping
There is error, cause the benchmark processed twice different, reduce machining accuracy, while clamping back and forth
Certain operation is increased, is indirectly caused the reduction of working (machining) efficiency, and is allowed labor intensity to be increased.
The content of the invention
The technical problem to be solved in the present invention is to provide that a kind of machining accuracy is high, working (machining) efficiency is good, and works strong
The hard Vehicle Processing technique of the low odd-side drive gear of degree.
To solve the above problems, the present invention is adopted the following technical scheme that：This kind of hard Vehicle Processing technique mainly for
The processing of baroque odd-side drive gear, it is characterised in that using following procedure of processing：
The first step：Change frock clamp
Second step：Positioning and clamping
3rd step：Finishing processing.
Further, the idiographic flow that the first step changes frock clamp is：The processing technique is needed using special
Expander frock carry out, first the universal fixture scroll chuck on lathe is unloaded, installs special on its position
Expander frock clamp；This kind of expander frock is when in use by the hydraulic mechanism in lathe carrying out workpiece
Clamping.
Further, the concrete mode of second step positioning and clamping is：Install special expander frock clamp
Afterwards, first with the endoporus 1 on workpiece as anchor point, endoporus 1 is positioned into stretching, while allowing D end faces to be pasted in
On the end face of fixture.
Further, after workpiece installation to be processed, inspection confirmation is carried out, first with hard Vehicle Processing
To needing the cylindrical of operation to be processed operation, afterwards again by hard turner skill to these three shoulders of A, B, C face
Face machines, and completes the processing operation in cylindrical and shoulder face.
The beneficial effect of the hard Vehicle Processing technique of odd-side drive gear of the present invention is：This kind of hard Vehicle Processing technique is adopted
Special expander frock clamp with endoporus as anchor point, with D end faces as reference plane, it is ensured that essence during clamping
Exactness, allows workpiece carry out multiple clamping when other faces are processed, it is to avoid error in clamping process and
Error, it is ensured that the precision of processing, also indirectly improves working (machining) efficiency, and reduces clamping times, allow
Labor intensity has also obtained certain reduction.
Description of the drawings
Fig. 1 be present invention is generally directed to odd-side drive gear sectional view；
Fig. 2 is the FB(flow block) of the hard Vehicle Processing technique of the odd-side drive gear of the present invention.
1：Endoporus；A, B, C are shoulder face；D is end face
Specific embodiment
Refering to shown in Fig. 2, a kind of hard Vehicle Processing technique of odd-side drive gear, this kind of hard Vehicle Processing technique master
To be directed to the processing of baroque odd-side drive gear (as shown in Figure 1)；Described processing technique is concrete
Be divided into following steps：
The first step：Change frock clamp
The processing technique needs to carry out using special expander frock, first by the universal fixture scroll chuck on lathe
Unload, special expander frock clamp is installed on its position；This kind of expander frock passes through lathe when in use
Interior hydraulic mechanism is carrying out the clamping of workpiece；
Second step：Positioning and clamping
After installing special expander frock clamp, first with the endoporus 1 on workpiece as anchor point, endoporus 1 is positioned
Stretching, while allowing D end faces to be pasted on the end face of fixture；
3rd step：Finishing processing
After workpiece installation to be processed, inspection confirmation is carried out, first with hard Vehicle Processing to needing the cylindrical of operation
Operation is processed, A, B, C is machined in these three shoulder faces by hard turner skill again afterwards, is completed
The processing operation in cylindrical and shoulder face.
The beneficial effect of the hard Vehicle Processing technique of odd-side drive gear of the present invention is：This kind of hard Vehicle Processing technique is adopted
With special expander frock clamp with endoporus as anchor point, with D end faces as reference plane, it is ensured that during clamping
Degree of accuracy, allows workpiece carry out multiple clamping when other faces are processed, it is to avoid the error in clamping process
And error, it is ensured that the precision of processing, working (machining) efficiency is also indirectly improve, and reduces clamping times,
Labor intensity is allowed also to obtain certain reduction.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto,
Any change or replacement expected without creative work, should all be included within the scope of the present invention.
Therefore, the protection domain that protection scope of the present invention should be limited by claims is defined.
