Description
Technical field
The present invention relates to a kind of processing methods of Step Shaft.
Background technique
Step Shaft is widely applied in machining, assembly industry, therefore its processing technology reasonability also directly affects
To processing efficiency and cost.Step axis processing technique largely uses cylinder bar directly to pass through Lathe turning tool or grinding machine sand at present
Gradually feed cutting/grinding to foreign round is taken turns, such processing method machining allowance is larger, and processing efficiency is lower, and processing waste material is
Iron filings shape can not recycle, and can only scrap processing, and cost waste is serious.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of processing methods of Step Shaft, to reach
To the purpose for improving processing efficiency, being recycled to processing remaining material head point.
The present invention is achieved by the following technical solutions:
A kind of processing method of Step Shaft, includes the following steps:
(1) selection cylinder bar is as blank, the clamping blank on lathe, and pacifies respectively on the knife rest of lathe
Encapsulation spot facing cutter and cutting tool, the sets of holes cutter includes annular blade, the annular blade along the blank axial direction
It arranges and opposite with blank end, the cutting tool is located at the side of the blank and the radial direction cloth along the blank
It sets；
(2) start lathe, blank rotation, while the sets of holes cutter is fed to the direction close to blank, thus in blank
Annular groove is dug on end, after the annular groove dug out reaches specified depth, sets of holes cutter feed-disabling is simultaneously retracted into initial position,
The blank for digging out annular groove is known as semi-finished product；
(3) start cutting tool, cutting tool accomplishes flat direction feeding to close, so that the outer circle to semi-finished product carries out
Cutting completes cutting when cutting tool reaches the annular groove root of the semi-finished product, and semi-finished product form Step Shaft after cutting
Finished product, cutting down part is a complete annular stub bars.
As the preferred embodiment of the above method, the axial line of the annular blade and the axial line of the blank are located at
On same straight line.
As the preferred embodiment of the above method, the axial line of the annular blade is equal with the axial line of the blank
Row.
As the preferred embodiment of the above method, in the step (2), the rotation speed of the blank is 400~
500r/min, the feed speed of the sets of holes cutter are 0.1mm/rin.
As the preferred embodiment of the above method, in the step (3), the feed speed of the cutting tool is
0.07mm/rin。
The present invention has the advantage that compared with prior art
A kind of processing method of Step Shaft provided by the invention uses sets of holes cutter to dig ring in cylinder bar end first
Then shape slot cuts cylinder bar outer circle using cutting tool, it is only necessary to which Step Shaft finished product, energy can be obtained in two step processes
Machining allowance is effectively reduced, simplifies process, process velocity is fast, and process time is greatly saved, and improves processing efficiency；And it cuts
The material head cut off is complete annular stub bars, which can carry out secondary operation into other components, have
The value utilized again, is greatly saved cost.

Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
Referring to Fig. 1 to Fig. 3, present embodiment discloses a kind of processing methods of Step Shaft, include the following steps:
(1) selection cylinder bar is as blank 1, the clamping blank 1 on lathe, and installs respectively on the knife rest of lathe
Sets of holes cutter 2 and cutting tool 4, sets of holes cutter 2 include annular blade, and annular blade is arranged along the axial direction of blank 1 and and base
Expect that 1 end is opposite, cutting tool 4 is located at the side of blank 1 and arranges along the radial direction of blank 1；Wherein, when needing to process
Step Shaft finished product 5 be concentric steps axis when, the axial line of the axial line and blank 1 of annular blade is located on the same line；
When the Step Shaft finished product 5 to be processed is eccentric Step Shaft, the axial line of annular blade is parallel with the axial line of blank 1.
(2) start lathe, blank 1 rotates, and the rotation speed of blank 1 is 400~500r/min, and different lathes is corresponding
Rotation speed is different, and the present embodiment is preferably 470r/min, while sets of holes cutter 2 is fed to the direction close to blank 1, trepanning tool
The feed speed of tool 2 is 0.1mm/rin, to dig annular groove 7 on 1 end of blank, the annular groove 7 dug out reaches specified depth
After degree, 2 feed-disabling of sets of holes cutter is simultaneously retracted into initial position, and the blank 1 for digging out annular groove 7 is known as semi-finished product 3；
(3) start cutting tool 4, cutting tool 4 accomplishes flat direction feeding, the feed speed of cutting tool 4 to close
For 0.07mm/rin, to be cut to the outer circle of semi-finished product 3, when cutting tool 4 reaches 7 root of annular groove of semi-finished product 3
When, cutting is completed, semi-finished product 3 form Step Shaft finished product 5 after cutting, and cutting down part is a complete annular stub bars 6.
Above step is that the processing of Step Shaft is stretched for single shaft, as long as repeating the above procedure of processing for Double shaft-extension Step Shaft
?.
Comprehensive utilization processing can be carried out to the ring-like material head cut down according to the actual situation, can be processed into annular shaft class zero
The components that component or size are met the requirements, such as axle envelope flange, shaft coupling.
The processing method of a kind of Step Shaft provided by the invention, in addition to that can effectively reduce machining allowance and promote processing efficiency
Outside, it is complete annular stub bars 6 that biggest advantage, which also resides in the part cut down, can be carried out to the complete annular stub bars 6
Secondary use, can by the components that annular stub bars 6 are processed into annular shaft element or size is met the requirements, as axle envelope flange,
Shaft coupling etc., is greatly saved production cost.And the difference in diameter of Step Shaft is bigger, processing efficiency is higher, the ring of saving
6 utility value of shape material head is also bigger.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
