Abstract
An object is to provide a lacing method for stators, which is capable of automatically effecting lacing with respect to the coil ends of stators different in diameter. Before lacing is effected with respect to the coil end of a stator, an eccentricity (A) between the movement axis (Z2) of a thread supply nozzle (5) and the rotation axes Z1a, (Z1) of the stators is calculated on the basis of the inner diameter of the stator and the nozzle length of the thread supply nozzle (5). When lacing is to be effected with respect to the coil end (2a) of a stator (1a) whose diameter differs from a reference diameter, the stator (1a) is moved in such a manner as to deviate the rotation axis (Z1a) of the stator (1a) by an amount corresponding to the eccentricity (A) from the movement axis (Z2) of the thread supply nozzle (5), so that lacing can be effected with respect to the coil end (2a) of the stator (1a) while the thread supply nozzle (5) is still used without changing the movement locus of a hook (4).

Embodiment
Below, with reference to accompanying drawing the preferred forms that lacing method of the present invention is specialized is described.Therefore, the summary of representing the lacing method of execution mode at Fig. 1.In Fig. 1, (a) expression situation that the coil-end of the stator of datum diameter is tightened, (b) expression situation that the coil-end of the stator of non-datum diameter is tightened.
The lacing method of present embodiment, as shown in Figure 1, make stator 1 each angle of rotating regulation, simultaneously by moving on the direction of principal axis of said stator 1 and the nozzle 5 of supply line and can on the direction of principal axis of said stator 1 and radial direction, moving, and the mutual action of the hook 4 of the line that provides of traction nozzle 5, and to tightening from the outstanding coil-end 2 of the both ends of the surface of stator core 3.
In the lacing method of present embodiment, determine at first how many shifting axle Z2 of the relative nozzle 5 of rotation axis Z1 of stator 1 departs from.At this, offset A determines according to the mouth of nozzle 5 internal diameter long and stator 1 (stator core 3).Because the internal diameter of the stator 1 of tightening and the mouth of nozzle 5 are long known, thereby can calculate offset A simply.
When being the stator 1 in benchmark footpath, offset A calculate A=0, become the shifting axle Z2 and the not eccentric and consistent state (state shown in Fig. 1 (a)) of the rotation axis Z1 of stator 1 of nozzle 5.Be performed as follows tightening coil-end 2 thereafter.
At this, with reference to the order that Fig. 2～Figure 16 explanation is tightened the coil-end 2 of this stator 1.Coil-end 2 is because outstanding from the both ends of the surface of stator core 3, though thereby also two coil-end are tightened because any one coil-end is all tightened with identical order, therefore here only tightening in proper order of a coil-end described.
At first, as shown in Figure 2, nozzle 5, be positioned at coil-end 2 above state under, from nozzle 5 supply lines 9.The front end of the line of being supplied with by nozzle 59 is kept by pin 7, and the line of being supplied with by nozzle 59 is tightened up and opens and establish.
Under this state, as shown in Figure 3, nozzle 5 just moves to the inside of stator core 3 to the below of coil-end 2.Nozzle 5 keeps the mouth maintaining part 6 of nozzle 5 axially to move by making.Hook 4 extends to the radial direction inboard of stator core 3.This hook 4 passes from the bottom (between coil-end 2 and the stator core 3) of coil-end 2, moves to the position that engages with line 9.
Thereafter, hook 4 at its front end draught line 9, retreats to the radial direction outside of stator core 3 as shown in Figure 4, pulls out line 9 from the bottom of coil-end 2.
Then, as shown in Figure 5, hook 4 is moved upward by the outside of coil-end 2 under the state of front end draught line 9.Thus, form circle R1 on online 9.At this moment, nozzle 5 also is moved upward.
Then, as shown in Figure 6, hook 4 extends to the radial direction inboard of stator core 3 once more.At this moment, hook 4 is by the top of coil-end 2, and its front end enters the inboard of stator core 3, the line 9 that traction is supplied with by nozzle 5.
Thereafter, as shown in Figure 7, hook 4 its front end draught lines 9 retreat by circle R1 to the radial direction outside of stator core 3.Form circle R2 on online thus 9.
Then, as shown in Figure 8, hook 4 moves downwards by the outside of coil-end 2 under the state of front end draught line 9.Thus, will enclose R2 and pull to the below.At this moment, nozzle 5 also moves downwards.
Under this state, as shown in Figure 9, hook 4 extends to the radial direction inboard of stator core 3 once more.At this moment, hook 4 as shown in figure 10, by the bottom of coil-end 2, its front end enters the inboard of stator core 3, the line 9 that traction is supplied with by nozzle 5.
Then, as shown in figure 11, hook 4 its front end draught lines 9 retreat by circle R2 to the radial direction outside of stator core 3.Thus, form circle R3 on online 9.
Thereafter, as shown in figure 12, hook 4 is moved upward by the outside of coil-end 2 under the state of front end draught line 9.Thus, will enclose R3 and pull to the top.At this moment, nozzle 5 also is moved upward.
In addition, make this moment stator core 3 (stator 1) only rotate the angle of regulation.The rotation of this stator core 3 is undertaken by indexing mechanism as shown in figure 13.This indexing mechanism is made of the pallet P and the motor M that keep stator core 3.At the periphery formative gear G of pallet P, the gear MG of this gear G and motor M side engagement.Thus, if motor M is rotated, indexing mechanism then can make stator core 3 related pallet P together rotate
After making stator core 3 rotations, as shown in figure 14, hook 4 extends to the radial direction inboard of stator core 3 again.Carry out as Fig. 6～operation shown in Figure 14 thereafter.Thus, can use line 9 that coil-end 2 integral body are seamed into mesh-shape.
When finally tightening, the operation carried out as Fig. 6～shown in Figure 8 after, as shown in figure 15, will from line 9 that nozzle 5 supply with cut off thereafter.At this moment, by forming last circle Rn on the hook 4 online 9.Cut terminal line 9e, as shown in figure 16, the last circle Rn by line 9 strains knotting.So, the tightening that just be through with to coil-end 2.
At this, to describing with the tightening of stator 1a of the different path lengths of datum diameter.In the lacing method of present embodiment, under the situation that the coil-end 2a of the stator 1a different to diameter tightens, shown in Fig. 1 (b), make the rotation axis Z1a off-centre of stator 1a.Just make the shifting axle Z2 of the relative nozzle 5 of rotation axis Z1a of stator 1a only depart from offset A.
Like this, the shifting axle Z2 off-centre of the relative nozzle 5 of rotation axis Z1a by making stator 1a makes the inner peripheral surface of the front end of nozzle 5 and stator 1a approaching.Just can make the configuration relation of the inner peripheral surface of nozzle 5 and stator 1a be equal to the configuration relation of the inner peripheral surface of nozzle 5 shown in Fig. 1 (a) and stator 1.Thus, can not change the long nozzle 5 that uses of mouth, not change the motion track of hook 4 and the coil-end 2a of the different stator 1a of diameter is tightened.Therefore, on the production line of the lacing method that uses present embodiment, can mix the different stator of diameter, automatically the coil-end of each stator be tightened.
More than, as describe in detail, in the lacing method of present embodiment, before the coil-end of stator is tightened, calculate the offset A of the rotation axis Z1a (Z1) of the shifting axle Z2 of nozzle 5 and stator according to the mouth length of the internal diameter of this stator and nozzle 5.When thus the coil-end 2a with the stator 1a of datum diameter different-diameter being tightened, because stator 1a is moved, so that the shifting axle Z2 of the relative nozzle 5 of rotation axis Z1a of stator only departs from offset A, thereby can not change the motion track of hook 4, former state is used nozzle 5, and the coil-end 2a of stator 1a is tightened.Just, can automatically tighten the coil-end of the different stator of diameter according to the lacing method of present embodiment.
Above-mentioned execution mode is an illustration, and the present invention without any qualification, as long as in the scope that does not break away from its purport, is certainly carried out all improvement and distortion.
