Specific embodiment
Explanation is further explained to the present invention with reference to specific embodiment.
It is rectangle or square or other cross sectional shape conductor bending formings that the manufacture of hair clip conductor, which is needed by cross sectional shape, single
An only hair clip conductor gives forming shape as shown in Figure 1, being mainly made of three parts, two straightways 1,2, end bending segment
3, it needs to be inserted into straightway in the slot of stator rotor in subsequent process, and two is carried out for exposing rotor end face part
Secondary torsion（It turns one's head）.
The integral arrangement of hair clip conductor on stator rotor before turning one's head is as shown in Fig. 2, concealed rotor body in figure.
It can be seen that whole hair clip conductor is formed by two layers shown in Fig. 2, internal layer and outer layer, according to the difference of motor, other forms
Arrangement be it is existing, such as 4 layers, 6 layers or more layers.The main problem that this patent solves is how to utilize the list shown in figure one
Body gives shaping hair clip conductor, is assembled into whole hair clip conductor as shown in Figure 2 automatically（The number of plies can be two layers or other illustrated
The number of plies of quantity）, and hair clip conductor assembly integral retaining holding position and shape are fitted into electric machine rotor.
Embodiment 1
The first hair-pin conductor assembling mechanism, as shown in Figure 3, Figure 4, including indexing rotary jig 5, on annulus along the circumferential direction
Be equally spaced several toothed regions 51, the gap 52 between adjacent toothed region 51 and hair clip Inside and Outside of Conductor side straightway size phase
Match somebody with somebody.
Using the method for the assembling conductor of above-mentioned fixture, step is：1st, rotary jig 5 is indexed to return along the indexing centre of gyration
Turn, stop afterwards in place；2nd, hair clip conductor declines along its geometric center, and its geometric center and hair clip conductor are on indexing fixture
Centre of gyration B is overlapped, and the posture of hair clip conductor is two straightways 1,2（Shown in Fig. 1）Respectively in the interior outside of fixture；3rd, drop to
Behind II positions, hair clip conductor needs to turn round along hair clip conductor centre of gyration B, is turned back to III positions；4th, under IV hair clips conductor continues
Drop height arrives the final position of short transverse；5th, V hair clips conductor is turned round in the corresponding conductor slot in fixture, indexing revolution
The indexing revolution of fixture 5 prepares the loading of next hair clip conductor；6th, repeat the above steps until all hair clip conductors are packed into indexing
On rotary jig 5, the assembly of final hair clip conductor is formed on indexing rotary jig 5.
Above-mentioned action, which can be interrupted, to be implemented step by step or is carried out continuously.Wherein 3, the purposes of 4,5 steps be in order to
It will not be interfered when hair clip conductor bar is packed into the adjacent hair clip conductor installed into slot.Fixture and hair clip conductor bar
It turns round and moves up and down and various ways realization, such as electropneumatic type of drive may be employed, do not influence the dynamic of substantive requirement
Work order.
Embodiment 2
Second of hair-pin conductor assembling mechanism, as shown in Figure 10, Figure 14, Figure 17, including fixture, by 11 groups of outer shroud 9 and inner ring
Into having the slot 10 for being along the circumferential direction used for hair clip conductor /V on outer shroud 9, have in inner ring 11 and be along the circumferential direction used for hair clip conductor
The hole 12 of positioning is inserted into, inner ring 11 connects inner ring driving turntable 18 and driven by motor, and outer shroud 9 connects outer shroud driving turntable 17 simultaneously
It is driven by motor.
Using the method for the assembling conductor of above-mentioned fixture, step is：9 He of hair clip conductor insertion fixture outer shroud as shown in Figure 1
In inner ring 11, one of straightway 1 is inserted into interior annular distance 12, another straightway 2 is by 10 /V of fixture outer shroud limiting slot；With
Rear jig inner ring and outer rings are with identical rotating speed and turn to indexing revolution, carry out being repeatedly inserted into for next hair clip conductor, such as scheme
11；2. step in repeating 1 is until all hair clip conductors are entirely insertable completion, inner and outer ring indexing revolution stopping-Figure 12；3rd, inner ring 11
Negative direction turns round, and outer shroud 9 keeps former gyratory directions revolution or slack, and all hair clip conductors for being inserted into fixture are returned in inner ring 11
Under the drive turned, assemble automatically to inner ring 11, due to inner ring grip size and the arrangement on it and motor of hair clip conductor
Rotor is identical, so final inner ring fixture forms the assembly phase with corresponding electric machine rotor hair clip conductor when stopping operating
Same assembly, assembly is located on inner ring fixture, such as Figure 13.
The core of this method is that fixture inner and outer ring is giving the equidirectional same rotating speed revolution of loading phase, gives inner ring after the completion of loading
Reversed turning, outer shroud can continue to turn round along former direction or stopping is not turned round the inner and outer ring after free state, final molding and stopped
Rotation stop is moved.Although attached drawing illustrates only a kind of prepackage of steering and a kind of final assembling of steering, as long as former according to above-mentioned core
Then, function can equally be realized by being changed to other steering combination.The mode of driving revolution can be electronic, pneumatic or its other party
Formula.
With the matching used clamping device for integrally taking out conductor after assembling of fixture, as shown in Figure 16, Figure 18, including solid
Determine body 21, outer layer rotary disk 23, outer layer supporting rod 24, internal layer rotary disk 25, internal layer supporting rod 26, internal layer supporting rod and outer layer folder
It holds bar to be made of drive pin 27, connecting rod 28, fulcrum post 29, clamping pin 30, as shown in figure 15, the insertion of 27 one end of drive pin is outer
In layer rotary disk 23 or internal layer rotary disk 25 corresponding hole, 27 other end of drive pin is connected with connecting rod 28, connecting rod 28 and
Clamping pin 30 is connected by fulcrum post 29, and 30 outer diameter of clamping pin is oriented to by the limition orientation set 31 installed on fixed body 21, can edge
Guide sleeve is reciprocating, which can reduce frictional resistance and then realize guiding.The along the circumferential direction uniform cloth of clamping pin 30
It puts, when the outer layer rotary disk 23 and internal layer rotary disk 25 that drive pin 27 is inserted into turn round, drive pin 27 is driven to move simultaneously, is driven
Pin 27 drives clamping pin 30 reciprocating along the guide sleeve on fixed body 21 by connecting rod 28, it is achieved thereby that all clampings
The synchronous function of radially clamping each hair clip conductor of pin 30.
To solve supporting rod circumference quantity and free space contradiction, for internal layer supporting rod 26 and outer layer supporting rod 24
Using layered arrangement mode, outer supporting rod shares a revolution outer layer drive disk 23 for two layers, and there are two 26 two layers of interior supporting rods
Internal layer drive disk 25 drives, using rigid connection between two drive disks.Supporting rod cloth can be increased or decreased according to this clamping device
The number of plies put, at the same drive disk can be every layer it is independent can also be shared.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope of present disclosure, technique according to the invention scheme and its
Design is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
