Description
Technical field
The present invention relates to field of machining, and in particular to the processing method of multistart worm.
Background technology
The turnery processing of multistart worm occupies very important position in mechanical manufacturing field.The turning bull on lathe
Worm screw is one of currently used processing method.The tooth form of worm screw is much like with trapezoidal thread, and tooth comparision is big, but due to worm screw
The deep areas of cut of tooth depth it is big, cutting when be difficult hold；The parted hair of each helix of multistart worm also compares mesh difficulty such as
Fruit error is big, will differ the multiple thread pitch of institute's car, reduces screw rod service life.
It is straight in axial plane that multistart worm, which is divided into axial straight wide worm screw and two kinds of straight sided normal worm ZN-worm, the former tooth form,
Line is the tooth form and the former contrast of curve the latter in normal plane.Multistart worm has special technical requirements processing
During must limit the accumulated error worm tooth shapes errors of worm thread axial pitch deviation axial directions should be no within tolerance
The transmission accuracy of worm gear will then be influenced.The coarse of screw thread flank of tooth of worm screw will influence the wearability and service life of working surface.
The content of the invention
To solve the above-mentioned problems, it is simple to provide a kind of process by the present invention, it is ensured that the processing quality of workpiece, reduces
Difficulty of processing and production cost, the processing method for improving the multistart worm of production efficiency.
The processing method of multistart worm of the present invention, comprises the following steps：
The first step, rough forging material, using No. 45 steel rough forgings；
Second step, on CA6140 lathes, clamps workpiece, rough turn blank is cylindrical with scroll chuck；
3rd step, heat treatment, modifier treatment；
4th step, on CA6140 lathes, clamps workpiece, face work centering, then reverses end for end the car other ends with scroll chuck
Face is to overall length, centering；
5th step, with two thimble clampings, half smart car is each cylindrical, stays 0.5 millimeter of allowance；
6th step, the cylindrical length of smart car screw thread, chamfering to drawing requirement size；
7th step, chooses worm screw roughing tool, point of a knife width 1.6mm-1.7mm, 39 ° -40 ° of nose angle, 20 ° -25 ° of cutting edge inclination；Snail
Bar finishing tool, point of a knife width 1.8mm, 40 ° of nose angle, 0 ° -4 ° of cutting edge inclination；
8th step, rotating speed is 40 revs/min during rough threading, and when smart car is 12 revs/min, is cooled down using emulsion, using inverted car
Processing, using upper slide rest scale parted hair method；
9th step, rough turn two worm threads, process first helicla flute, until groove depth, slot bottom with roughing tool cutting to left and right method
Wide desired size, and margin scale when remembeing upper slide rest cutting to left and right；Then roughing Article 2 helicla flute, at this moment by small cunning
Plate is moved forward or rearward, and the moving range of small slide plate is added no more than the margin scale of first helicla flute during cutting to left and right
Upper displacement distance, until completing Article 2 helicla flute；
Tenth step, two screw threads of smart car worm screw to drawing requirement size, change worm screw finishing tool, first helicla flute of smart car, first car
Into the first face, then the second face of smart car, control flume bottom width and groove depth, and the roughness of helicla flute two sides is paid attention to, until completing the
One helicla flute, and remember the margin scale of upper slide rest during cutting to left and right, Article 2 helicla flute is finished, small drag is pulled forward
Or certain distance is moved rearwards, depending on the distance is by screw-nut gap, first car is into one side, then smart car another side, before upper slide rest
The distance moved afterwards is that the Derivative limit on the left or on the right scale of first helicla flute upper slide rest ensures that groove depth slot bottoms are wide plus displacement distance
Size and two side roughness；
Whether the 11st step, the normal tooth thickness for measuring adjacent two tooth meet drawing size, if satisfied, then worm tooth shape part processes
Complete, otherwise, is corrected untill size is met to worm tooth shape depending on margin value.With file to flank, wedge angle and burr
Finishing；
12nd step, smart car each several part are cylindrical；
13rd step, is examined.
Process of the present invention is simple, it is ensured that the processing quality of workpiece, reduces difficulty of processing and production cost, improves life
Produce efficiency.
