Description
Technical field
The present invention relates to field of machining, and in particular to the processing method of minor diameter two-wire inner trapezoidal thread.
Background technology
The multi-thread internal thread of minor diameter is processed on center lathe, due to being limited by aperture, lathe tool knife bar can not possibly be too thick, and
Limited by thread form, tool bit part is also smaller, so turning, measurement and chip removal are more difficult, and multi-thread inner trapezoidal thread is due to screw thread
Lift angle is big, will also increase the difficulty of processing of workpiece.
The content of the invention
To solve the above-mentioned problems, the present invention, which provides one kind, can reduce lathe tool pressure, chip removal is smoothly it also avoid knife
Phenomenon, strengthens lathe tool rigidity, prevents lathe tool from vibrating, and can ensure the processing quality of part, improves the small straight of production efficiency
The processing method of footpath two-wire inner trapezoidal thread.
The processing method of minor diameter two-wire inner trapezoidal thread of the present invention, comprises the following steps：
The first step, it is first that bottom outlet car is good by dimension precision requirement, the turning of two helicla flutes is completed with Lathe Tool for Cutting Trapezoid Threads afterwards,
Two straight lines vertical with axis are made at the alveolus bottom for being located at institute's turning, sharp as long as two point of a knife of threading tool is on the basis of slot bottom is wide
Knife is borrowed in slot bottom for wide or so, control depth of threat progress turning to complete with middle slide plate rough turn with small slide plate, since cutter head is tiny,
Depth of threat and slot bottom is wide borrows points of 4 layers progress turning of the skill in using a kitchen knife in cookery to be advisable using straight method and left and right；
Second step, first layer turning, small slide plate move forward dial to " 0 " position, utilize several knives of the straight turning of middle slide plate to 0.5
After mm depths, depth is constant, and Lathe tool tip divides to the right a few knife turning to pay attention to disappearing at this time to the wide extended line corresponding position of slot bottom along small slide plate
Except just adding graduating with cutter degree behind small slide plate gap；
3rd step, second layer turning, small slide plate scale is constant, and car is to aggregate depth 1mm at central diameter for straight point of several knives of middle slide plate, then
Lathe tool depth is constant, catches up with knife point of a knife processing groove is widened to 1.4mm forward with small slide plate, and slot bottom is widened to groove width etc. at central diameter
In transverse tooth thickness, make at two point of a knife cars to the horizontal line of first time processing, i.e., alveolus top is rough turn finishes；
When 4th step, third and fourth layer of turning, mobile small slide plate make the point of a knife continue as started between groove point two layers of turning to alveolus extremely
Desired size is deep, that is, completes rough turn；
5th step, smart car is sharp by each knife face grinding of cutter head with oilstone, respectively two tooth side of fine feed smart car, until using single line
Untill plug thread gauge screws properly, the allowance of tooth both sides is wanted at this time；
6th step, a pitch is moved forward by lathe tool along slide plate, spiral with the rough turn Article 2 of method of rough turn first helicla flute
Groove, with the identical middle spiral molar both sides of small slide plate surplus smart car Article 2 of first helicla flute of smart car.
The present invention can reduce lathe tool pressure, make chip removal smoothly, it also avoid knife phenomenon, lathe tool rigidity is strengthened, is prevented
Lathe tool vibrates, and can ensure the processing quality of part, improves production efficiency.
Embodiment
The processing method of invention minor diameter two-wire inner trapezoidal thread, comprises the following steps：
The first step, it is first that bottom outlet car is good by dimension precision requirement, the turning of two helicla flutes is completed with Lathe Tool for Cutting Trapezoid Threads afterwards,
Two straight lines vertical with axis are made at the alveolus bottom for being located at institute's turning, sharp as long as two point of a knife of threading tool is on the basis of slot bottom is wide
Knife is borrowed in slot bottom for wide or so, control depth of threat progress turning to complete with middle slide plate rough turn with small slide plate, since cutter head is tiny,
Depth of threat and slot bottom is wide borrows points of 4 layers progress turning of the skill in using a kitchen knife in cookery to be advisable using straight method and left and right；
Second step, first layer turning, small slide plate move forward dial to " 0 " position, utilize several knives of the straight turning of middle slide plate to 0.5
After mm depths, depth is constant, and Lathe tool tip divides to the right a few knife turning to pay attention to disappearing at this time to the wide extended line corresponding position of slot bottom along small slide plate
Except just adding graduating with cutter degree behind small slide plate gap；
3rd step, second layer turning, small slide plate scale is constant, and car is to aggregate depth 1mm at central diameter for straight point of several knives of middle slide plate, then
Lathe tool depth is constant, catches up with knife point of a knife processing groove is widened to 1.4mm forward with small slide plate, and slot bottom is widened to groove width etc. at central diameter
In transverse tooth thickness, make at two point of a knife cars to the horizontal line of first time processing, i.e., alveolus top is rough turn finishes；
When 4th step, third and fourth layer of turning, mobile small slide plate make the point of a knife continue as started between groove point two layers of turning to alveolus extremely
Desired size is deep, that is, completes rough turn；
5th step, smart car is sharp by each knife face grinding of cutter head with oilstone, respectively two tooth side of fine feed smart car, until using single line
Untill plug thread gauge screws properly, the allowance of tooth both sides is wanted at this time；
6th step, a pitch is moved forward by lathe tool along slide plate, spiral with the rough turn Article 2 of method of rough turn first helicla flute
Groove, with the identical middle spiral molar both sides of small slide plate surplus smart car Article 2 of first helicla flute of smart car.
The present invention determines amount of movement of the lathe tool in helicla flute using slot bottom width as feed foundation, with Lathe tool tip is wide, layering
Processing, reduces lathe tool pressure, makes chip removal smoothly, it also avoid knife phenomenon.Due to coarse-fine car select in, small slide plate control into
Knife, scale is clearly demarcated, easy to the foundation after lathe tool one pitch of movement as Article 2 helicla flute, so as to reach two-wire trapezoidal thread
Separated time precision and each line central diameter it is equal.Since lathe tool cutter head is at the half of lathe tool thickness, increase to greatest extent
The cross-sectional area of lathe tool knife bar, strengthens lathe tool rigidity, prevents lathe tool from vibrating, and thread surface roughness value is reached will
Seek size.
