The manufacturing installation of the stator with skewed slot

Technical field

The present invention relates to the manufacturing installation of stator of band skewed slot, coil is installed on form by laminated magnetic sheet metal and be applied in and reverses and make the stator core that this sheet metal staggers gradually.

Background technology

In the past, the stator of electric rotating machine possessed cylindric stator core and stator coil, and wherein stator core has and is arranged in radial and outstanding to internal diameter direction multiple teeth (magnetic pole) and multiple slits of opening between multiple tooth; Stator coil is installed in said stator core by coil edge is contained in above-mentioned slit.Stator core is formed by stacked multiple magnetic metal sheet, and stator coil and this stator core manufacture respectively, afterwards, the stator coil of ring-type are contained in each slit of stator core.

On the other hand, known following manufacturing method for stators, that is: although rotor (gyrator) is inserted in such stator after, but in order to make the smooth rotation of this rotor, and in the mode applying to reverse (deflection), apply continuous print attraction or repulsive force between the magnetic pole of rotor to its stator core, make vibration and the noise reduction of this electric rotating machine.And, as the concrete manufacture method of the stator of such band skewed slot, propose there is following method, that is: after coil being inserted into this slit under the state that slit is parallel with the axis of stator core, reverse magnetic sheet metal and stagger (for example, referring to patent documentation 1) gradually to make them.As shown in figure 12, in the manufacture method of the stator of band skewed slot, in advance the grooving 2a matched each other is set in the periphery of the multiple sheet metals 2 forming stator core 1, and after the slit 6 not shown coil being inserted into stator core 1, plate 3 inserts by the grooving 2a along the coupling of multiple sheet metal 2, make this plate 3 carry out rotating its axle center relative to stator core 1 is tilted as represented in solid arrow, make multiple sheet metal 2 stagger gradually thus.

In addition, as shown in figure 14, as the manufacturing installation of the stator of other band skewed slot, also propose there is following manufacturing installation, that is: newel 8 is inserted into the inner circumferential of stator core 1 in the mode that can retreat, and is formed with the spiral helicine twisting inducing part 8a (such as with reference to patent documentation 2) in the slit opening portion being inserted into stator core 1 in the periphery of this newel 8.In the manufacturing installation of the stator of this band skewed slot, do not apply to reverse to the magnetic metal sheet of stator core 1, but coil 7 is inserted under the state that slit is parallel with the axis of stator core, then deflection newel 8 is inserted into the inside of stator core 1 as represented in solid arrow from an end face of stator core 1.So the spiral helicine guide portion 8a being formed at deflection newel 8 is just inserted in the slit opening portion of the inner circumferential of stator core 1, and each magnetic metal sheet forming stator core 1 is owing to being reversed and deflection by spiral helicine guide portion 8a.At this, the label 9 in Figure 14 represents the supporting member 9 supported the stator core 1 being inserted with coil 7.

Patent documentation 1: Japanese Unexamined Patent Publication 11-225461 publication (segment number " 0008 ", " 0009 ")

Patent documentation 2: Japanese Unexamined Patent Publication 11-299187 publication (segment number " 0008 ", " 0009 ")

But, as shown in figure 12, by making the plate 3 being inserted into grooving 2a rotate the manufacturing installation reversed in the described patent documentation 1 of stator core 1, be formed at the grooving 2a of the periphery of multiple sheet metal 2 as shown in the dotted arrow of Figure 13, the periphery along the sheet metal 2 forming stator core 1 is moved with arc-shaped.On the other hand, when the plate 3 making to be inserted into this grooving 2a tilts relative to the axle center of stator core 1, then the plate 3 being inserted into grooving 2a of the end of stator core 1 as shown in the solid arrow of Figure 13 with rectilinear movement.Therefore, the still remaining problem that should solve as follows, that is: when increasing the torsion degree of stator core 1, then initial inserted plate 3 can depart from from this grooving 2a, thus there is boundary at increase torsion degree this respect.

In addition, shown in Figure 14 deflection newel 8 is pressed into and stator core 1 is applied reverse above-mentioned patent documentation 2 manufacturing installation in, because the spiral helicine twisting inducing part 8a in fact carrying out deflection is formed directly the periphery of this newel 8, therefore in order to change torsion degree, other the newel 8 of the spiral helicine twisting inducing part 8a being formed on the outer periphery the torsion desired by applying must be prepared, be thus difficult to change its torsion degree.

In addition, after torsion is applied to stator core 1, as represented in dotted arrow, this deflection newel 8 must be extracted from stator core 1.But, in fact the spiral helicine twisting inducing part 8a owing to carrying out deflection is formed directly into the periphery of this newel 8, if therefore do not make the stator core 1 of deflection or this deflection newel 8 as one man rotate with its torsion degree, then there is defect newel 8 cannot extracted as the crow flies from this stator core 1.Therefore, the still remaining problem that should solve as follows, that is: need the new construction that this stator core 1 or deflection newel 8 are rotated accordingly with its torsion degree, and this structure is very complicated.

In addition, after applying to reverse to stator core 1, multiple magnetic metal sheet is bonded with each other by welding etc. to keep its state needs.But even the stator core that the magnetic metal sheet of stacked regulation sheet number is formed, when producing gap between this magnetic metal sheet and magnetic metal sheet, then the thickness of its stacked direction can produce difference.Therefore, there is following unfavorable condition, even if the torsion that is: desired by applying, when making multiple magnetic metal sheet be bonded with each other under the discrepant state of the thickness of stacked direction, being then difficult to the stator of the band skewed slot obtaining uniform quality.And, about the method controlling its thickness generation difference when stator core 1 engages, do not record in citing document 1 and 2.

In this condition, the handle part 69b at the two ends of operating grip 69 is held in hand by operator, and as shown in the solid arrow of Fig. 9, makes this operating grip 69 with the central shaft of stator core 11 for pivot rotates.Like this, pin 54 relative to pedestal 51 tilting action, as shown in Fig. 3 (b), the magnetic metal sheet 16 of pin 54 is inserted in grooving 16a, pressed by pin 54 and rotate around newel 63, and twisting action is applied to magnetic metal sheet 16, thus the stator 10 being with skewed slot can be obtained.Therefore the torsion corresponding to the anglec of rotation of functional unit 67 is applied to stator core 11, thus in this device 50, by adjusting the anglec of rotation of functional unit 67, easily can adjust the degree of the torsion of stator core 11 thus.

When reversing stator core 11, then the grooving 16a of each sheet metal 16 connects in the mode depicting the spiral of releiving.But, in present embodiment, because the multiple annular plates 61 preventing the pin 54 being inserted through this grooving 16a from departing from from grooving 16a embed stator core 11, so this pin 54 is prohibited to depart from from grooving 16a because of multiple annular plate 61.Therefore, this pin 54 is gently strain along the grooving 16a connected in the mode describing spiral, and can not depart from from this grooving 16a.Therefore this pin 54 makes each magnetic metal sheet 16 rotate effectively, thus the plate 3 departed from from this grooving 16a with the use in the past shown in Figure 12 compares the device that stator core 11 applies to reverse, this device 50 can increase the degree of torsion, thus can apply larger torsion to stator core 11.

After reversing stator core 11 with the angle of expection, utilize pressing component 56 to press the stator core 11 after this torsion.Specifically, as shown in the amplification view of Figure 10, the upper end of pillar 55 is inserted into the access aperture 56a of pressing component 56, a part for the lower surface of this pressing component 56 is abutted with another end face of stator core 11.And, the external screw thread 57 of the patchhole 56b being inserted into pressing component 56 is threadedly engaged with internal thread hole 55a, thus the pressing component 56 that lower surface abuts with another end face of stator core 11 is crimped on pedestal 51 side.By pressing stator core 11 like this, the magnetic metal sheet 16 of formation stator core 11 being close to magnetic metal sheet 16, thus can not gap being produced between which.And value that its sheet number obtains is consistent to make the thickness of the stacked direction of stator core 11 and the thickness of this magnetic metal sheet 16 be multiplied by.

By applying to reverse to stator core 1 like this, make after magnetic metal sheet 16 and magnetic metal sheet 16 be close to mutually, multiple magnetic metal sheet 16 to be bonded with each other.As shown in Figure 10, when stator core 11 engages, functional unit 67 is pulled down together with operating grip 69, further the pin 54 applying stator core 11 to reverse also is pulled down.Because this pin 54 erects setting in the mode can dismantled relative to pedestal 51, even if so after applying to reverse to stator core 11, also can dismantle.And, remove the link of connecting member 62, make multiple annular plate 61 overlapped, and the periphery of stator core 11 is exposed.In the present embodiment, represent the situation of being welded by multiple magnetic metal sheet 16, go up in the stacking direction and a part for the periphery of the stator core 11 exposed by making multiple annular plate 61 overlapping is welded.Wherein, the Reference numeral 83 in Figure 10 represents the solder bar 83 for welding this stator core 11.Like this, even if use multiple annular plates 61 that anti-shotpin 54 departs from from grooving 16a, owing to making above-mentioned annular plate 61 overlapping, the periphery of stator core 11 can be made thus to expose, and therefore the plurality of annular plate 61 can not hinder the joint of stator core 11.And, owing to being formed with the pedestal 53b of end face of the below of mounting stator core 11 on mounting block 53, so the end face of the below of stator core 11 except the actual part being placed in this pedestal 53b becomes floating skyborne state.Therefore, even if such as weld the periphery of the stator core 11 near this mounting block 53, solder bar 83 also can be avoided to contact with this mounting block 53, thus this solder bar 83 can be utilized to weld till the end face of stator core 11 to below effectively.

By applying to reverse to stator core 1 like this, magnetic metal sheet 16 is engaged closely with magnetic metal sheet 16, thus obtain the stator 10 (Fig. 3 (b)) being with skewed slot, afterwards the stator 10 of the band skewed slot obtained like this is pulled down from device 50.When pulling down the stator 10 of band skewed slot, first external screw thread 57 being pulled down from internal thread hole 55a, afterwards pressing component 56 being pulled down from pillar 55, removing the pressing of this pressing component 56 pairs of stator cores 11.And, the stator 10 of the band skewed slot surrounded by multiple pillar 55 is lifted upward and extracts from device 50.Therefore, when pulling down the stator core 11 after applying torsion, without the need to making stator core 11 or newel 63 rotate, thus comparing with the device making stator core 1 or newel 8 rotate that needs when this is pulled down in the past shown in Figure 14, it can be made to construct simplification.

In the stator 10 (Fig. 3 (b)) of the band skewed slot utilizing device 50 of the present invention to manufacture, owing to making stator core 11 deflection, so magnetic metal sheet 16 has and to stagger gradually and to the tooth 13 of oblique inclination, at adjacent tooth 13 to each other, the upper end edge circumference of one side, extremely close to the lower end of the opposing party, successfully can carry out the rotation of not shown rotor thus.

And, this stator core 11 is formed by the magnetic metal sheet 16 of stacked regulation sheet number, but due between this magnetic metal sheet 16 and magnetic metal sheet 16, do not produce gap state under be bonded with each other, thus the difference of the thickness of the stacked direction of stator core 11 can not be produced.Namely, be threadedly engaged with internal thread hole 55a by the external screw thread 57 of the patchhole 56b by being inserted into pressing component 56, thus the pressing component 56 that lower surface abuts with another end face of stator core 11 is crimped on pedestal 51 side, and welds the periphery of stator core 11 vertically in this condition.Therefore by managing the power that external screw thread 57 is threadedly engaged with internal thread hole 55a, just can apply suitable pressure to the stator core 11 of cascade type, and weld the periphery of stator core 11 in this condition vertically, thus the thickness that the thickness of the stacked direction of stator core 11 is this magnetic metal sheet 16 is multiplied by the value that its sheet number obtains, and the difference of the thickness of the stacked direction of stator core 11 can not be produced.Therefore when the stator 10 of band skewed slot with the stator core 11 formed by the sheet number of the stacked regulation of magnetic metal sheet 16 of same thickness, when utilizing device 50 of the present invention to manufacture, the always identical stator core of thickness 11 can be become.That is, in device 50 of the present invention, freely can adjust the degree of torsion, thus the thickness of the stacked direction of whole stator core 11 that can make the magnetic metal sheet 16 of stacked regulation sheet number and be formed is even.

Be in the annular plate 61 that can split in the formation shown in Figure 11, a pair circular arc parts 61b, 61c are formed as circular, the intercommunicating pore 61d of the respective other end of a pair circular arc parts 61b, 61c being supported by axle by making one end is interconnected, and in this condition locking pin 84 is inserted this intercommunicating pore 61d, thus, the other end being configured to a pair circular arc parts 61b, 61c preventing one end from being supported by axle is decontroled mutually.And, under the state mutually decontroled preventing the other end, multiple annular plate 61 is embedded the periphery of stator core 11, its inner circumferential is close to the periphery of stator core 11 thus, thus when applying to reverse to stator core 11, can the state of affairs generation that departs from from grooving 16a of anti-shotpin 54.

On the other hand, after applying to reverse to stator core 1, multiple magnetic metal sheet 16 is bonded with each other, but now, extracted by the locking pin 84 in the intercommunicating pore 61d of the respective other end by being inserted into a pair circular arc parts 61b, 61c, and as the dotted line arrows, the other end of a pair circular arc parts 61b, 61c making one end be supported by axle is decontroled mutually, can take out stator core 11 thus between the other end of this liberation.Like this, by the multiple annular plates 61 be made up of a pair circular arc parts 61b, 61c are pulled down from stator core 11, the periphery of stator core 11 can be made to expose, and can weld a part for the periphery of the stator core 11 exposed in the stacking direction.Thus, above-mentioned multiple annular plate 61 can be easily avoided to become the obstacle of stator core 11 joint.

In addition, in the above-described embodiment, to possessing upper plate 63b, lower plate 63a and linking multiple connecting rod 63c of this upper plate 63b and lower plate 63a, and the light-dutyer newel 63 being formed with space between multiple connecting rod 63c is illustrated, as long as but not producing the weight of operational obstruction, newel also can be formed as columned solid parts.

In addition, in the above-described embodiment, the manufacturing installation 50 of operating grip 69 rotation that projection 69a is inserted in the upper medium pore 63d of newel 63 is illustrated, but if functional unit 67 can be made with the central shaft of stator core 11 for pivot rotates, then this newel 63 can not be set.

In addition, in the above-described embodiment, the periphery being used in stator core 11 forms the grooving 16a that is interconnected and the manufacturing installation 50 possessing the pin 54 being inserted through this grooving 16a is illustrated, although not shown, but pin also can be inserted through the coconnected slit 14 of axis of stator core 11 in the inner circumferential of stator core 11.
