Below in conjunction with accompanying drawing the utility model is described in further detail: referring to Fig. 1, drive system comprises the kinematic pair of three reference axis, and X-axis is made as elongates axle, is used for the length of side of drawing of coil.Servomotor 1 by shaft coupling 2 direct connection ball-screws 3 and ball screw 3 ', drag the reciprocating table 4 that four axle sleeves dress main spindle box is housed and vertically move, finish coil the pulling out and returning of the length of side in winding process.Be decided to be the initial point O of X-axis at certain rational position of left end, X=O herein, the curved of coil all carries out at initial point around promptly crooked 180 ° (90 °).Y-axis is made as bending axis, be used for going for a stroll of coil, promptly crooked 180 ° (90 °), servomotor with connect by the power shaft of shaft coupling with decelerator 6, worm screw 7 direct connections of the output shaft of decelerator and the worm gear pairs on the bending axis, drag worm gear 8 and bending axis Y and finish in the coil winding process operation program of crooked 180 ° (90 °), this program is to carry out at the initial point O of X-axis.The B axle is made as the milling feed axle, and the rotary feed that is used for milling cutter main cutting gyration mills crooked 180 ° (90 °) thickening in the formation of R place.Servomotor 9 connects by the power shaft of shaft coupling with decelerator 10, worm screw 11 direct connections of the worm gear on the output shaft of decelerator 10 and the milling feed axle, drag worm gear and milling feed axle B is rotated round feeding, finish the feed motion program that milling thickens, last mill principal axis II is parked in a fixed position, and this operation program carries out at initial point O.The following kind of drive is adopted in the principal cutting movement of milling cutter rotation: motor 13 drives power transmission shaft 17 by driving pulley 14, V belt 15, passive belt wheel 16, I axle by the shaft gear 17 ' miniature milling head of drive of this axle head, this II axle is equipped with milling cutter 18 and carries out principal cutting movement, rotary feed is carried out in the rotation of milling cutter own again, finishes the task that milling thickens jointly.Referring to Fig. 2, bend and be sleeved in turn together around main shaft Y, milling feed axle B, milling power transmission shaft 17 and line die drawing bar 19 these four axles, wherein curved is hollow shaft around main shaft Y, milling feed axle B, milling power transmission shaft 17, rotate during work, have an axis of rotation, it is coaxial to have realized feeling relieved layer by layer, is convenient to the dismounting maintenance.And line die drawing bar 19 is a solid hopkinson bar, moves up and down during work.Referring to Fig. 3 to Fig. 6, comprise that screw rod 20 and half screw, 21, half screws 21 are connected with miniature milling head 22.Rotating screw bolt 20 top square toes can make milling head 22 and milling cutter adjust up and down.Milling head 22 is provided with milling head latch segment 23, after milling cutter mixes up up and down, rotates hexagon socket head cap screw 24, makes its locking.Referring to Fig. 7, auxiliary routine in the coiling base program is finished by hydraulic system, comprise and mill pincers clamping cylinder 24, curved forceps clamping cylinder 25, line mould clamping cylinder 26 and lift cylinders 27, add one way pressure-reducing valve 28 before milling pincers clamping cylinder 24, curved forceps clamping cylinder 25, line mould clamping cylinder 26, so that adjust the pressure of each cylinder, add hydraulic control one-way valve 29 before the lift cylinders 27, so that pressurize does not descend lifting platform voluntarily.During real work, the transmission process of bending axis Y-axis is in the drive system: servomotor 5 → shaft coupling → decelerator 6 → worm screw 7 → worm gear 8 and bending axis Y; The transmission process of milling feed axle B axle is: servomotor 9 → shaft coupling → decelerator 10 → worm screw 11 → worm gear 12 and milling feed axle B; The transmission process that elongates the axle X-axis is: servomotor 1 → diaphragm type shaft coupling 2 → ball-screw 3 → ball screw 3 ' and reciprocating table 4; The transmission process of milling principal cutting movement is: motor 13 and driving pulley 14 → V-belt 15 → passive belt wheel 16 → power transmission shaft 17 and axle tooth 17 ' → miniature milling head I axle → miniature milling head II axle and milling cutter 18 rotations.The utility model adopts and is interrupted technique for coiling, winding process is decomposed into draws straight line, bending, mill and thicken three base programs, finishing of these three base programs needs other auxiliary routines to guarantee, as draw straight line to need to mill that pincers unclamp, to carry out under the situation that line mould and curved forceps clamp, go for a stroll need tight at curved forceps line die clamp, mill under the situation that pincers unclamp and carry out, milling to thicken needs milling that clamp is tight, carrying out under the situation that line mould and curved forceps clamp.These major-minor programs are got up continuously, just constituted the winding process that carries out automatically.The coiling program is as follows: (1) curved forceps, line mould clamp simultaneously → (2) crooked → (3) mill pincers tight → (4) mill thicken → (5) mill pincers and open → (6) pull out → (7) mill pincers tight → (8) curved forceps, line mould open simultaneously → (9) are curved to be returned → (10) draw and return.And in the past the coiling program of strip on edge winding machine was: (1) curved forceps clampings → (2) line die clamp is tight → (3) crooked → (4) mill clamp tight → (5) mill thicken → (6) mill pincers and unclamp → (7) pull out straight line → (8) curved forceps unclamp → (9) curved forceps returns → (10) mill clamp tightly → (11) line mould unclamps → (12) pull out and return.Contrast as can be seen from new procedures and original program, new coiling program is different fully with original program, is kept to ten programs by 12 programs, and precedence is also different, and the tight and pine of curved forceps line mould carries out simultaneously, has shortened cycle period, has improved coiling efficient.Pull out from (6) in the new coiling program → (7) mill pincers tight → (8) curved forceps, line mould open simultaneously → (9) are curved to be returned → after (10) are drawn and milled pincers the process of returning and clamp earlier, curved forceps, line mould are with opening, bend again and return, draw and return, milling drawing of pincers like this, to return clamping force big, be in the middle part of line material again, be difficult for becoming flexible, can improve the grade of turn-to-turn and spend together.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1. the lathe reciprocating table moves (X-axis is drawn straight line), curved around rotating (Y-axis rotation bending), milling Three coordinates of feeding (feeding of B axle slewing circle) move the repetitive positioning accuracy of paying and greatly improve, such as reciprocating table The repetitive positioning accuracy of mobile (pull out, draw and return initial point O) is within 0.01mm, and this is between coil turn The impact of unevenness degree is vital;

2. owing to adopted digital control system at X, Y, B axle, thus make elongate axle X, curved around axle Y, mill Cutting speed and the location of feed shaft B can both adjust accurately and conveniently, brings machine during for the coiling specifications vary The very big convenience that bed is adjusted;

3. because best speeds match between the innovation of coiling program and each program is put forward coiling efficient greatly Height improves 30% than the program control flat machine that waters;

4. the coil turn of coiling is asked unevenness degree≤0.5mm, no cydariform, and neat appearance meets technology fully Requirement. Make every group of coil gross thickness reduce by 12～15mm owing to mill to thicken, for electric machine temperature rise in service is asked Condition has been created in the solution of topic;

5. greatly simplify the structure, failure rate is low, noise is low, and no greasy dirt is conducive to environmental protection.
