Abstract
The invention discloses a machining method of a step shaft. The machining method comprises the following steps: (1) selecting a cylindrical bar as a blank and clamping the blank on a lathe; mounting a sleeve hole tool and a cutting tool on a tool rest of the lathe respectively; (2) starting the lathe and rotating the blank; meanwhile, feeding the blank in a direction, close to the blank, of the sleeve hole tool, and digging an annular groove in an end part of the blank to form a semi-finished product; (3) starting the cutting tool and feeding the cutting tool in a direction close to the semi-finished product, so as to cut the excircle of the semi-finished product; when the cutting tool reaches a root part of the annular groove of the semi-finished product, finishing cutting; after cutting the semi-finished product, forming a step shaft finished product, wherein a cut-off part is a complete annular stub bar. The machining method of the step shaft has the advantages that the step shaft finished product can be obtained through two steps of procedures so that the machining allowance can be effectively reduced and the machining efficiency is improved; the cut-off annular stub bar can be utilized for the second time so that the cost is greatly saved.

Iron filings shape, it is impossible to recycle, can only scrap process, and cost wastes serious.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, there is provided a kind of processing method of Step Shaft, to reaching
Divide the purpose being recycled to raising working (machining) efficiency, to processing remaining material head.
The present invention is achieved by the following technical solutions:
A kind of processing method of Step Shaft, comprises the steps:
(1) choose cylinder bar as blank, clamping described blank on lathe, and pacify respectively on the knife rest of lathe
Encapsulation spot facing cutter and cutting tool, described trepanning tool tool includes annular blade, and described annular blade is along the axial direction of described blank
Arrange and relative with blank end, described cutting tool is located at the side of described blank and the radial direction cloth along described blank
Put；
(2) start lathe, blank rotates, described trepanning tool has and feeds near the direction of blank simultaneously, thus in blank
Cannelure is dug on end, after the cannelure digging out reaches the depth specified, trepanning tool tool feed-disabling is simultaneously retracted into initial position,
The blank digging out cannelure is referred to as semi-finished product；
(3) start cutting tool, cutting tool accomplishes flat direction feeding to close, thus carrying out to the cylindrical of semi-finished product
Cutting, when cutting tool reaches the cannelure root of described semi-finished product, completes to cut, forms Step Shaft after semi-finished product are cleaved
Finished product, cutting down part is complete annular stub bars.
As the preferred implementation of said method, the axial line of described annular blade is located at the axial line of described blank
On same straight line.
As the preferred implementation of said method, the axial line of described annular blade is equal with the axial line of described blank
OK.
As the preferred implementation of said method, in described step (2), the rotary speed of described blank is 400～
500r/min, the feed speed of described trepanning tool tool is 0.1mm/rin.
As the preferred implementation of said method, in described step (3), the feed speed of described cutting tool is
0.07mm/rin.
The present invention has the advantage that compared to existing technology
A kind of processing method of Step Shaft that the present invention provides, it digs ring initially with trepanning tool tool in cylinder bar end
Shape groove, is then cut it is only necessary to two step operations can get Step Shaft finished product, energy using cutting tool is cylindrical to cylinder bar
Effectively reduce allowance, simplify operation, process velocity is fast, greatlys save process time, improves working (machining) efficiency；And cut
The stub bar cutting off is complete annular stub bars, and this complete annular stub bars can carry out secondary operations and become other parts, have
The value reusing, greatlys save cost.

Specific embodiment
Below embodiments of the invention are elaborated, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following enforcements
Example.
Referring to Fig. 1 to Fig. 3, present embodiment discloses a kind of processing method of Step Shaft, comprise the steps:
(1) choose cylinder bar as blank 1, clamping blank 1 on lathe, and be respectively mounted on the knife rest of lathe
Trepanning tool tool 2 and cutting tool 4, trepanning tool tool 2 includes annular blade, and annular blade is along the axial arranged of blank 1 and and base
Expect 1 end relatively, cutting tool 4 is located at side and the radial direction arrangement along blank 1 of blank 1；Wherein, when need process
Step Shaft finished product 5 be concentric steps axle when, the axial line of annular blade is located on the same line with the axial line of blank 1；
When Step Shaft finished product 5 to be processed is eccentric Step Shaft, the axial line of annular blade is paralleled with the axial line of blank 1.
(2) start lathe, blank 1 rotates, the rotary speed of blank 1 is 400～500r/min, and different lathes is corresponding
Rotary speed is different, and the present embodiment is preferably 470r/min, and trepanning tool tool 2 is near the feeding of the direction of blank 1, trepanning tool simultaneously
The feed speed of tool 2 is 0.1mm/rin, thus digging cannelure 7 on blank 1 end, the cannelure 7 digging out reaches the depth specified
After degree, trepanning tool has 2 feed-disablings and is retracted into initial position, and the blank 1 digging out cannelure 7 is referred to 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, thus cutting to the cylindrical of semi-finished product 3, when cutting tool 4 reaches cannelure 7 root of semi-finished product 3
When, complete to cut, after semi-finished product 3 are cleaved, form Step Shaft finished product 5, cutting down part is complete annular stub bars 6.
Above step is to stretch the processing of Step Shaft for single shaft, as long as repeating above procedure of processing for Double shaft-extension Step Shaft
?.
Comprehensive utilization processing can be carried out according to practical situation to the ring-like stub bar cutting down, annular shaft class zero can be processed into
Part or size meet the parts requiring, such as axle envelope flange, shaft coupling etc..
A kind of processing method of Step Shaft that the present invention provides, except can effectively reduce allowance and lifting working (machining) efficiency
Outward, maximum be also advantageous in that the part cutting down is complete annular stub bars 6, this complete annular stub bars 6 can be carried out
Annular stub bars 6 can be processed into annular shaft element or size and meet the parts requiring by secondary utilization, such as axle envelope flange,
Shaft coupling etc., greatlys save production cost.And the difference in diameter of Step Shaft is bigger, its working (machining) efficiency is higher, the ring of saving
Shape stub bar 6 value is also bigger.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Any modification, equivalent and improvement of being made within principle etc., should be included within the scope of the present invention.
