The use process of this overlength screw rod processing milling machine is specifically introduced below：
1st, the clamping of workpiece 9：
As depicted in figs. 1 and 2, first in workpiece 9（Do not have threaded iron staff or rod iron as）One end（That is Fig. 1-Fig. 4
In right-hand member）Process and cylindrical coaxial screw（Screw hole dimensions are identical with the ends screw of traction screw mandrel 16）, then screw
Fixed handle 4, fix main shaft housing 5 and the position fed between base 7, in order to install workpiece 9, by workpiece 9 from feeding
Passed through in the central through hole of the feeding main shaft of mechanism and pass through chuck 6, be then passed through（Or pass through）Prepare after support frame 11 and draw
Screw mandrel 16 connects, then expansion chuck 6；Screw mandrel 16 is drawn by one end away from support frame 11 in draw nut 20（That is Fig. 1-Fig. 4
In right-hand member）Screw in, the termination for drawing screw mandrel 16 is screwed into the termination screw of workpiece 9 and tightened, that is, complete workpiece 9
Installation, the link position of traction screw mandrel 16 and workpiece 9 is access site 19, for the feed of milling-cutting cutter disc 12.Now, if opened
Dynamic feeding motor 3, then feeding main shaft can drive workpiece 9 to do circular-rotation together with traction screw mandrel 16（Electrical control positive and negative rotation）,
Because traction screw mandrel 16 rotates in draw nut 20, and draw nut 20 is fixed in towing bracket 21, so, traction
Together with workpiece 9, and can while rotation makees axially rectilinear movement to screw mandrel 16.
2nd, to knife and milling：

Whole feed mechanism is moved to move together；Start feeding motor 3, stop after excluding the gap between traction screw mandrel 16 and draw nut 20
Car, to good milling-cutting cutter disc 12 by the access site 19 of traction screw mandrel 16（Completed using feed handle 15）Afterwards, then cutter spacing is being entered
Putting 19 adds knife now to terminate to the requirement of workpiece screw thread to knife.During milling, first start milling motor 14, restart feeding motor
3, because workpiece 9 both does circular-rotation, axial rectilinear movement is done again, and milling-cutting cutter disc 12 is fixed in addition to rotation, so, milling
Movement locus of the milling cutter on workpiece 9 on sharpener disk 12 is the helix on traction screw mandrel 16, and so, workpiece 9 is milled out
Screw rod be and the screw rod that draws 16 identical screw thread of screw mandrel.
3rd, the Milling Process of long bolt：
As shown in figure 3, when the length of screw flight is more than feed mechanism and is feeding the displacement of base 7, now should
Chuck 6 is unclamped, main shaft housing 5 is moved on into one end away from haulage gear 18 on feeding base 7（That is Fig. 1-Fig. 4 left end）Now
Workpiece 9 will not move, and then clamp workpiece 9 with chuck 6 again, as shown in figure 1, start milling motor 14 and feeding motor 3, this
Sample, just it can continue milling screw rod again.If secondary milling is not met by the requirement of screw flight length, by upper program
Again or more time operation.From the foregoing, it will be observed that this overlength screw rod processing milling machine can process the screw rod of endless in theory.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as
The technical scheme that can be realized on the basis of above-described embodiment without creative work, it is regarded as falling into patent of the present invention
Rights protection scope in.
