Description

A kind of processing method of worm screw axle sleeve helical tooth of rotor spinning machine
Technical field
The present invention relates to the processing method of worm screw axle sleeve, refer in particular to, the processing method of the worm screw axle sleeve helical tooth on a kind of rotor spinning machine belongs to the Machining Technology field.
Background technology
On rotor spinning machine, the worm screw swivel nut is the joggle piece of feed roller plastics worm gear, in running, worm screw axle sleeve helical tooth beat (radial motion) and roughness directly has influence on service life of feed roller plastics worm gear.Under normal operating condition, the allowing to beat of the relative centre bore of helical tooth of worm screw axle sleeve has only 0.03mm, and the length of helical tooth is less than the length of screw rod axle sleeve, and namely helical tooth does not extend to another top end of worm screw axle sleeve, structure is more special, has therefore brought certain difficulty to processing.Existing processing method has three kinds:
First method: as shown in Figure 3: with the helix processing tooth portion of moulding slotting cutter 14 along worm screw axle sleeve 3, this method machining accuracy height, but need repeatedly feed or very low feeding speed just can process whole tooth surface, cutter wear is serious, working (machining) efficiency is very low, milling cutter is very short service life during batch process, so the whole processing cost of this processing method is very high.
Second method: with screw-rolling machine or thread rolling machine processing, repeatedly pushing tooth portion and be shaped, is benchmark machining center hole with tooth portion again.The method precision of beating does not reach requirement, and helical tooth by terminal because repeatedly extruding causes tooth portion out-of-shape, presentation quality is very poor, can not satisfy instructions for use.
The third method: adopt engine lathe processing, because the helical tooth of worm screw axle sleeve does not extend to the end, no escape, the rotating speed that adds the lathe spindle in man-hour must very lowly can be finished withdrawing, therefore it is very low to add the cutting speed in man-hour, directly causes the fineness of helical tooth very poor; And because the withdrawing position is difficult to control, very easily forge a knife, generally also seldom adopt.
Because second kind of precision of processing with the third method can not reach instructions for use, adopt first kind of processing method at present mostly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing method of worm screw axle sleeve helical tooth of rotor spinning machine, can reduce the wearing and tearing to milling cutter under the prerequisite that guarantees required precision to greatest extent.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of processing method of worm screw axle sleeve helical tooth of rotor spinning machine is characterized in that, comprises following job step:
At first, clamp mandrel 2 with lathe scroll chuck 1, the blank of worm screw axle sleeve 3 be installed on the lathe mandrel 2, hold out against through hole end face on the worm shaft cover blank with the active thimble 10 on the lathe tailstock, make the lathe mandrel drive an axle worm shaft cover blank low speed rotation,
Loading onto milling cutter 5 at milling head 9 then also compresses with screw 4, and make the offset distance of the axis of milling head and mandrel axis greater than the tooth depth of helical tooth, milling head 9 connects with support 12 on being contained in the lathe middle carriage by bearing 11, motor 6 drives milling head 9 rotation at a high speed by the V belt 8 on the belt pulley 7, make the axle sleeve blank of low speed rotation on milling cutter 5 and the lathe mandrel become counter motion, thereby realized the processing to worm screw axle sleeve 3 helical tooths.
As preferred version, the offset distance of the axis of described milling head and mandrel axis is greater than the tooth depth 15mm of helical tooth, with handled easily.
As preferred version, the rotating speed<3rpm of described lathe mandrel, the rotating speed of described milling head are 1500rpm, decide according to the rigidity of system of processing.
Operation principle of the present invention and beneficial effect are:
Add man-hour, because of pivot (axis of the milling head) offset distance of milling cutter on the pivot (axis) of worm screw axle sleeve and the milling head tooth depth greater than helical tooth, milling cutter is processed in the mode of similar lathe tool interrupted cut, and because the lathe spindle rotating speed is very low, iron filings slabbing under the milling cutter cutting can not be wrapped in and causes lipper on the milling cutter, can take away a large amount of heat in metal cuttings again, the wearing and tearing of milling cutter are reduced greatly, greatly prolong its service life; And one-pass just can be finished the processing of whole helical tooth, has improved operating efficiency greatly.
Compare with first kind of processing method, improved more than 15 times in working (machining) efficiency under the prerequisite that satisfies the product required precision equally, the milling cutter life-span greatly prolongs, and has reduced processing cost, has improved economic benefit.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
A kind of processing method of worm screw axle sleeve helical tooth of rotor spinning machine comprises following job step:
At first, clamp mandrel 2 with lathe scroll chuck 1, the blank of worm screw axle sleeve 3 is installed on the lathe mandrel 2, holds out against through hole end face on the worm shaft cover blank with the active thimble 10 on the lathe tailstock, so just can make lathe spindle drive a worm shaft and overlap a blank low speed rotation.
Loading onto milling cutter 5 at milling head 9 then also compresses with screw 4, and make the offset distance of the axis of milling head and mandrel axis greater than the tooth depth of helical tooth, milling head 9 connects with support 12 on being contained in the lathe middle carriage by bearing 11, motor 6 drives milling head 9 rotation at a high speed by the V belt 8 on the belt pulley 7, make the axle sleeve blank of low speed rotation on milling cutter 5 and the lathe mandrel become counter motion, thereby realized the processing to worm screw axle sleeve 3 helical tooths.
As preferred version, the offset distance of the axis of described milling head and mandrel axis is greater than the tooth depth 15mm of helical tooth, with handled easily.
As preferred version, the rotating speed<3rpm of described lathe mandrel, the rotating speed of described milling head are 1500rpm, decide according to the rigidity of system of processing.
Add man-hour, because of pivot (axis of the milling head) offset distance of milling cutter on the pivot (axis) of worm screw axle sleeve and the milling head tooth depth greater than helical tooth, milling cutter is processed in the mode of similar lathe tool interrupted cut, and because the lathe spindle rotating speed is very low, iron filings slabbing under the milling cutter cutting can not be wrapped in and causes lipper on the milling cutter, can take away a large amount of heat in metal cuttings again, the wearing and tearing of milling cutter are reduced greatly, greatly prolong its service life; And one-pass just can be finished the processing of whole helical tooth, has improved operating efficiency greatly.
