As Fig. 1, Fig. 2, shown in Fig. 4 and Fig. 5, haulage gear 18 comprises traction screw mandrel 16, draw nut 20, limit screw 22 and the bracing frame 11 be installed on traction/milling base 17 and towing bracket 21, bracing frame 11 be installed near feed mechanism position and for supporting workpiece 9 so that traction/Milling Process, traction screw mandrel 16 is used for being connected with one end of workpiece 9 near one end of feed mechanism and the diameter of this linkage section is less than the diameter drawing screw mandrel 16 other parts forms access site 19 for milling feed, access site 19 is near bracing frame 11, away from the center screw of one end of feed mechanism through draw nut 20 on traction screw mandrel 16, towing bracket 21 is provided with central through hole, be fixedly connected with towing bracket 21 by limit screw 22 in the central through hole that draw nut 20 is set in towing bracket 21.
As depicted in figs. 1 and 2, milling mechanism comprises milling motor 14, (major part is in milling housing 13 for milling spindle, unmarked in figure), milling-cutting cutter disc 12, feed handle 15 and milling housing 13, by belt 2 transmission between milling motor 14 and milling spindle, milling-cutting cutter disc 12 be installed on milling spindle one end and for carrying out milling thread processing to workpiece 9, milling spindle is installed in milling housing 13, milling housing 13 is arranged on traction/milling base 17, feed handle 15 to be installed on milling housing 13 and traction/milling base 17 and for adjusting the relative position of milling housing 13 on traction/milling base 17 to adjust the position of milling-cutting cutter disc 12.
Below the use procedure of this overlength screw rod processing milling machine is specifically introduced:
1, the clamping of workpiece 9:
As depicted in figs. 1 and 2, first be at workpiece 9(and do not have threaded iron staff or rod iron) one end (right-hand member namely in Fig. 1-Fig. 4) process the screw (screw hole dimensions with the ends screw that draw screw mandrel 16 identical) coaxial with cylindrical, then be tightened handle 4, position between main shaft housing 5 and feeding base 7 is fixed, so that install workpiece 9, workpiece 9 is passed from the central through hole of the feeding main shaft of feed mechanism and passes chuck 6, be connected with traction screw mandrel 16 through preparing after (or passing through) bracing frame 11 again, then expansion chuck 6; Traction screw mandrel 16 is screwed in by the one end (right-hand member namely in Fig. 1-Fig. 4) away from bracing frame 11 in draw nut 20, the termination of traction screw mandrel 16 to be screwed in the termination screw of workpiece 9 and tightens, namely the installation of workpiece 9 is completed, traction screw mandrel 16 is access site 19 with the link position of workpiece 9, for milling-cutting cutter disc 12 feed.Now, if start feeding motor 3, then feeding main shaft can drive workpiece 9 to do circular-rotation (the positive and negative rotation of electrical control) together with traction screw mandrel 16, because traction screw mandrel 16 rotates in draw nut 20, and draw nut 20 maintains static in towing bracket 21, so traction screw mandrel 16 can do axial rectilinear movement together with workpiece 9 again while rotation.
2, tool setting and milling:
Unscrew fixed handle 4, the releasing between main shaft housing 5 with feeding base 7 is fixedly connected with, so that workpiece 9 drives whole feed mechanism to move together; Start feeding motor 3, stop after getting rid of the gap between traction screw mandrel 16 and draw nut 20, feed handle 15 is utilized to complete on access site 19 side of traction screw mandrel 16 to good milling-cutting cutter disc 12() after, then adding the requirement of cutter to workpiece screw thread at access site 19, now tool setting terminates.During milling, first start milling motor 14, restart feeding motor 3, because workpiece 9 both did circular-rotation, do again axial rectilinear movement, and milling-cutting cutter disc 12 is motionless except rotating extenal fixation, so, the movement locus of milling cutter on milling-cutting cutter disc 12 on workpiece 9 be the helix on traction screw mandrel 16, and like this, the screw rod milled out workpiece 9 is with the screw rod of the identical screw thread of traction screw mandrel 16.
3, the Milling Process of long bolt:
As shown in Figure 3, when the length of screw flight is greater than feed mechanism when the displacement of feeding base 7, now should unclamp chuck 6, main shaft housing 5 is moved on on feeding base 7 away from one end (i.e. the left end of Fig. 1-Fig. 4) of haulage gear 18 now workpiece 9 can not move, and then with chuck 6 clamping work pieces 9, as shown in Figure 1, start milling motor 14 and feeding motor 3, like this, just milling screw rod can be continued again.If when secondary milling can't meet the requirement of screw flight length, then again or more time to operate by upper program.As from the foregoing, this overlength screw rod processing milling machine can process the screw rod of endless in theory.
Above-described embodiment is preferred embodiment of the present invention; it is not the restriction to technical solution of the present invention; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of patent of the present invention.
