The wire package refers to a coil formed by winding a wire, and the structure of the wire package is generally a plurality of radially equally spaced single windings 2 formed by winding in the circumferential direction of the stator core 1. Since the wire stator needs to be assembled into a housing, if the inner and outer shapes and sizes of the wire stator are not fixed and irregular, it is easy to get stuck and cannot be assembled into the housing, which requires shaping of the wire package of the wire stator.

[0003] At present, the wire package of the wire stator is mainly fixed by an intermediate shaping tire, and the external wire package is shaped by a single-point rolling roller. In this shaping method, the roller will slide relative to the conductor of the wire package, so it is easy to damage the wire.

[0032] Compared with the content of the background technology introduction, the above-mentioned wire package shaping device for the wire stator is applied to the wire package shaping of the wire stator of the axial magnetic field motor, and includes a traction mechanism and an outer ring shaping mechanism. The traction mechanism includes a traction machine base with a first circular through hole in the middle, a traction arm arranged on the traction machine base and slidingly matched with the traction machine base along the radial direction of the first circular through hole, a traction claw arranged at the radial inner end of the traction arm, and a first driving component for driving the radial sliding of the traction arm; wherein, the traction arm corresponds to a single winding radially arranged in the circumferential direction of the stator core of the wire stator one by one, and the traction claw is used to insert into the gap between its corresponding single winding and the inner ring of the stator core and apply a traction force towards the axis direction of the wire stator to the single winding; the outer ring shaping mechanism includes a tightening machine base with a second circular through hole in the middle, a pressing arm arranged on the tightening machine base and slidingly matched with the tightening machine base along the radial direction of the second circular through hole, a pressing block arranged at the radial inner end of the pressing arm, and a second driving component for driving the radial sliding of the pressing arm; wherein, the number of the pressing arms is multiple and they are evenly arranged along the circumferential direction of the second circular through hole, and the radial end face of the pressing block along the second circular through hole is used to abut against and press the circumferential outer surface of the wire package located on the outer ring of the stator core of the wire stator. In the actual application process of the above-mentioned wire package shaping device, by inserting each traction claw into the gap between its corresponding single winding of the wire stator and the inner ring of the stator core, and then driving the traction arm to slide along the radial direction of the circular through hole on the traction machine base through the driving component, controlling the traction arm to slide towards the axis direction of the circular through hole, so that the traction claw applies a traction force towards the axis direction of the wire stator to the single winding. Since the traction arm corresponds to a single winding radially arranged in the circumferential direction of the stator core of the wire stator one by one, therefore, by driving each traction arm, the wire package located on the outer ring of the stator core can be made to fit more tightly with the outer ring of the stator core, so as to achieve the purpose of shaping the outer ring of the wire package of the wire stator. During this shaping process, since there is no sliding friction between the traction mechanism and the wire package, the problem of wire damage during wire package shaping is avoided; and by placing the wire stator into the circular through hole of the outer ring shaping mechanism, and then adjusting the pressing arm to slide, so that the radial end face of the pressing block along the circular through hole abuts against and applies to the circumferential outer surface of the wire package located on the outer ring of the stator core of the wire stator. Since the pressing arms are evenly arranged along the circumferential direction of the circular through hole, therefore, by driving each pressing arm to move radially and towards the axis direction of the circular through hole through the driving component, the circumferential outer surface of the wire package can be abutted and pressed by each pressing block. During this shaping process, there is no sliding friction between the pressing block and the wire package, so the problem of wire damage during wire package shaping can also be effectively avoided. In addition, through the step-by-step operation or synchronous operation of the above-mentioned traction mechanism and outer ring shaping mechanism, the outer ring of the wire package of the obtained wire stator can be made more flat and standard.

[0033] In addition, the present invention also provides a method for shaping the wire package of a wire stator. This method for shaping the wire package uses the device for shaping the wire package of a wire stator described in any of the above solutions, and specifically includes the following steps:

[0034] Step S1: Insert the respective traction claws of the traction mechanism into the gaps between the individual windings on the wire stator and the inner ring of the stator core, and drive the first drive assembly so that each of the traction claws exerts a traction force in the axial direction of the wire stator on its corresponding individual winding;

[0035] Step S2: Fit the outer ring shaping mechanism as a whole over the outer ring of the wire package of the wire stator, and drive the second drive assembly so that the pressing block abuts against and presses the circumferential outer surface of the wire package located on the outer ring of the stator core of the wire stator to a preset position;

[0036] Among them, Step S1 and Step S2 are executed step by step or synchronously.

[0037] Since the device for shaping the wire package of a wire stator has the above technical effects, and the method for shaping the wire package of a wire stator that uses the device for shaping the wire package of a wire stator inherits the core idea of the above method for shaping the wire package of a wire stator, it should also have corresponding technical effects, which will not be elaborated here.

Detailed implementation mode

[0061] The core of the present invention is to provide a wire package shaping device and method for a wire stator to solve the problem that the wire package shaping of the wire stator is prone to damage the wire.

[0062] In order to enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] As Figures 1-21 shown, a wire package shaping device for a wire stator provided by an embodiment of the present invention is applied to the wire package shaping of a wire stator of an axial magnetic field motor, and includes a traction mechanism and an outer ring shaping mechanism. The traction mechanism includes a traction base 4a with a first circular through-hole 3a opened in the middle, a traction arm 5a arranged on the traction base 4a and slidably matched with the traction base 4a along the radial direction of the first circular through-hole 3a, a traction claw 6a arranged at the radial inner end of the traction arm 5a, and a first drive assembly 7a for driving the traction arm 5a to slide radially; wherein, the traction arm 5a corresponds one-to-one with the single windings 2 arranged radially in the circumferential direction of the stator core 1 of the wire stator, and the traction claw 6a is used to insert into the gap between its corresponding single winding 2 and the inner ring of the stator core 1 and apply a traction force towards the axis direction of the wire stator to the single winding 2; the outer ring shaping mechanism includes a tightening base 4b with a second circular through-hole 3b opened in the middle, a pressing arm 5b arranged on the tightening base 4b and slidably matched with the tightening base 4b along the radial direction of the second circular through-hole 3b, a pressing block 6b arranged at the radial inner end of the pressing arm 5b, and a second drive assembly 7b for driving the pressing arm 5b to slide radially; wherein, the number of the pressing arms 5b is multiple and evenly arranged along the circumferential direction of the second circular through-hole 3b, and the radial end face of the pressing block 6b is used to abut against and press the circumferential outer surface of the wire package located on the outer ring of the stator core 1 of the wire stator.

[0064] In the actual application process of the above-mentioned wire package shaping device, each traction claw is inserted into the gap between a single winding of its corresponding wire stator and the inner circle of the stator core. Then, the driving component drives the traction arm to slide along the radial direction of the circular through-hole on the traction machine base, and controls the traction arm to slide towards the axis direction of the circular through-hole, so that the traction claw applies a traction force towards the axis direction of the wire stator to the single winding. Since the traction arm corresponds one by one to the single windings radially arranged in the circumferential direction of the stator core of the wire stator, by driving each traction arm, the wire package located on the outer circle of the stator core can be made to fit more tightly with the outer circle of the stator core, thus achieving the purpose of shaping the outer circle of the wire package of the wire stator. During this shaping process, since there is no sliding friction between the traction mechanism and the wire package, the problem of wire damage during wire package shaping is avoided; and by placing the wire stator into the circular through-hole of the outer circle shaping mechanism and then adjusting the pressing arm to slide, the pressing block abuts against and applies force to the circumferential outer surface of the wire package located on the outer circle of the stator core of the wire stator along the radial end face of the circular through-hole. Since the pressing arms are evenly arranged along the circumference of the circular through-hole, by driving each pressing arm radially and towards the axis direction of the circular through-hole through the driving component, the pressing blocks can abut against and press the circumferential outer surface of the wire package. During this shaping process, there is no sliding friction between the pressing block and the wire package, so the problem of wire damage during wire package shaping can also be effectively avoided. In addition, through the step-by-step operation or synchronous operation of the above-mentioned traction mechanism and outer circle shaping mechanism, the outer circle of the wire package of the obtained wire stator can be made more flat and regular.

[0065] Here it should be noted that for those skilled in the art, it should be understood that for an axial magnetic field motor, the specific structural form of the wire package on its wire stator is a plurality of single windings 2 radially and equally spaced around the circumference of the stator core 1. It should also be noted that the radially inner end of the above-mentioned traction arm refers to the end of the traction arm towards the axis direction of the first circular through-hole, and the radially outer end of the traction arm refers to the end of the traction arm away from the axis direction of the first circular through-hole. Additionally, it should be noted that the diameter of the first circular through-hole should not be less than the inner circle of the stator core of the wire stator to ensure that the traction claw 6a can be normally inserted into the gap between the inner circle of the stator core and the single winding. It should also be noted that the structure of the above-mentioned traction claw 6a is preferably arranged in a way that the wedge-shaped structure is perpendicularly connected to the traction arm, and specifically, it can be connected by welding, or other connection methods commonly used by those skilled in the art. By designing the traction claw into a wedge-shaped structure, it is more convenient for the traction claw to be inserted into the gap. In addition, in order to make the above-mentioned traction mechanism more convenient to use, the traction claw can be designed into a structure that protrudes both above and below, so that the traction mechanism has traction claws both above and below, and can shape two wire stators simultaneously.

[0066] It should also be noted that the radial inner end of the clamping arm refers to the end of the clamping arm facing the axial direction of the second circular through hole, and the radial outer end of the clamping arm refers to the end of the clamping arm facing away from the axial direction of the second circular through hole. It should also be noted that the diameter of the second circular through hole should not be less than the diameter of the wire package on the outer ring of the stator core of the wire stator, so as to ensure that the radial movement of the clamping arm can drive the circumferential surface of the wire package on the outer ring of the stator core of the pressure block 6b to fit and press. It should also be noted that the structure of the above-mentioned pressure block 6b preferably adopts an end face facing the axial direction of the circular through hole designed as an arc surface adapted to the outer ring of the wire package, and the method of connection with the clamping arm can specifically adopt welding connection, or other connection methods commonly used by technical personnel in this field. By designing the pressing block into an arc-shaped structure, the pressing block and the outer ring of the wire package are pressed more closely, which can better ensure the shaping quality. In addition, it should be noted that, generally speaking, when the pressing block is pressed against the outer ring surface of the wire package, each pressing block can basically occupy the entire circumferential surface of the wire package, and a preset movement gap is maintained between two adjacent pressing blocks to ensure that interference is avoided.

[0067] In some specific embodiments, the specific structural form in which the traction arm 5a and the traction machine base 4a form a sliding fit can be that the traction machine base 4a is provided with a first guide through hole arranged radially along the first circular through hole 3a, and the traction arm 5a passes through the first guide through hole and slides with the first guide through hole. By providing the first guide through hole, it can be ensured that the traction arm can only perform linear motion along the radial direction of the first circular through hole. Of course, it can be understood that the above is only a preferred example of the structure of the traction arm to achieve radial motion in the present invention. In actual application, it can also be other commonly used implementation structural forms by those skilled in the art, such as directly using the structural form of a telescopic cylinder, and the telescopic arm of the telescopic cylinder directly constitutes the implementation mode of the traction arm, and another example is that the upper surface of the traction machine base is provided with a radially arranged T-shaped slide rail, and the bottom of the traction arm is provided with a T-shaped groove that cooperates with the T-shaped slide rail, or the upper surface of the traction machine base is provided with a radially arranged T-shaped groove, and the bottom of the traction arm is provided with a T-shaped slide rail that cooperates with the T-shaped groove, etc., and various methods are all possible. In actual application, it can be selected and set according to actual needs.

[0068] Similarly, the specific structural form in which the above-mentioned pressing arm 5b and the pressing machine base 4b form a sliding fit may be that the second guiding through hole arranged radially along the second circular through hole 3b is provided on the tightening machine base 4b, and the pressing arm 5b passes through the second guiding through hole and slides with the second guiding through hole. By providing the above-mentioned second guiding through hole, it can be ensured that the pressing arm can only perform a linear motion along the radial direction of the second circular through hole. Of course, it can be understood that the above is only a preferred example of the structure of the present invention for the pressing arm to achieve radial movement. In the actual application process, it can also be other structural forms commonly used by those skilled in the art. For example, the structure of a telescopic cylinder can be directly adopted, and the telescopic arm of the telescopic cylinder directly constitutes the implementation manner of the above-mentioned pressing arm. Another example is that a T-shaped slide rail arranged radially is provided on the upper surface of the pressing machine base, and a T-shaped groove cooperating with the T-shaped slide rail is provided at the bottom of the pressing arm. Or a T-shaped groove arranged radially is provided on the upper surface of the pressing machine base, and a T-shaped slide rail cooperating with the T-shaped groove is provided at the bottom of the pressing arm. There are various ways such as these, and in the actual application process, it can be selected and set according to actual needs.

[0069] In a further embodiment, the specific structure of the above-mentioned first driving assembly 7a may include a first turntable ring 8a arranged on the traction machine base 4a and coaxially arranged with the first circular through hole 3a, and a first driver 9a for driving the first turntable ring 8a to rotate. First inclined chutes corresponding to the outer radial ends of the traction arms 5a one by one are provided in the circumferential direction of the first turntable ring 8a, and when the first turntable ring 8a rotates, the outer radial ends of the respective traction arms 5a all slide relative to their corresponding first inclined chutes, thereby forcing the respective traction arms 5a to perform synchronous linear sliding motions in the radial direction. By the above-mentioned manner of rotating the first turntable ring, the synchronous radial movement of the traction arms connected to the first turntable ring can be achieved, and only one first driver is required to drive the respective traction arms, and the driving structure is simpler and the operation is more convenient and fast. Of course, it can be understood that the above-mentioned manner of synchronously driving the traction arms by using the structure of the first turntable ring is only a preferred example of the embodiment of the present invention. In the actual application process, other driving methods commonly used by those skilled in the art can also be adopted. For example, the method of connecting a first driver to each traction arm, but the arrangement of the driving structure is relatively complex, and it is not easy to achieve synchronization and is not convenient for driving.

[0070] Similarly, the specific structure of the second driving component 7b described above may include a second turntable ring 8b disposed on the tightening base 4b and coaxially arranged with the second circular through hole 3b, and a second driver 9b for driving the second turntable ring 8b to rotate. Second inclined chutes corresponding to the outer radial ends of the pressing arms 5b one by one are provided in the circumferential direction of the second turntable ring 8b. When the second turntable ring 8b rotates, the outer radial ends of the pressing arms 5b all slide relative to their corresponding second inclined chutes, thereby forcing the pressing arms 5b to perform a radially synchronous linear sliding motion. By means of the rotation of the second turntable ring described above, the synchronous radial movement of the pressing arms connected to the second turntable ring can be achieved, and only one second driver is required to drive the pressing arms, so that the driving structure is simpler and the operation is more convenient and fast. Of course, it can be understood that the above-described method of synchronously driving the pressing arms by using the structure of the second turntable ring is only a preferred example of the embodiment of the present invention. In actual application, other driving methods commonly used by those skilled in the art can also be adopted, such as the method of connecting a second driver to each pressing arm. However, the arrangement of the driving structure is relatively complex, and it is not easy to achieve synchronization and convenience in driving.

[0071] It should be noted here that for an axial magnetic field motor, the wire windings of the stator core of its wire stator are generally arranged in a circumferential distribution. Therefore, the above-mentioned traction arms 5a are of equal length, and when the first turntable ring 8a rotates, the radial sliding path lengths of the traction arms 5a are the same. Similarly, the above-mentioned pressing arms 5b are of equal length, and when the second turntable ring 8b rotates, the radial sliding path lengths of the pressing arms 5b are the same.

[0072] In addition, it should be noted that the specific structural form of the first inclined chute may be a first waist-shaped through hole 10a provided on the disk surface of the first turntable ring 8a and arranged at an acute angle with the radial direction of the first turntable ring 8a. A first slider 11a capable of extending into the first waist-shaped through hole 10a is provided at the inner radial end of the traction arm 5a, and the first slider 11a can slide along the first waist-shaped through hole 10a. When the first slider slides along the first waist-shaped through hole, the first waist-shaped through hole can exert pressure on the first slider. Since the first slider is arranged in an inclined manner at an acute angle with the radial direction, when the first turntable ring rotates, the first waist-shaped through hole can force the first slider to drive the traction arm to perform a radial linear motion. Of course, it can be understood that the inclination angles of the above-mentioned first waist-shaped through holes relative to the radial direction should be the same to achieve synchronous and equal-length radial movement lengths. In addition, in order to avoid excessive relative sliding friction between the first slider and the inner wall of the first waist-shaped through hole and cause jamming, generally, the outer surface of the first slider can be designed to have a structure with a rolling sleeve, and the pure sliding structure between the first slider and the first waist-shaped through hole is changed into a rolling-sliding structure, thereby greatly reducing the frictional resistance and avoiding the occurrence of jamming.

[0073] In addition, it should be noted that the above arrangement of using the first waist-shaped through hole to form the first inclined chute is only a preferred example of the embodiment of the present invention. In actual application, the structure of the above first inclined chute can also be a first slope-shaped groove formed on the inner ring surface of the first turntable ring 8a and arranged at an acute angle to the radial direction of the first turntable ring 8a. The radially inner end of the traction arm 5a is provided with a first slider that slidably cooperates with the first slope-shaped groove. By rotating the first turntable ring, the first slope-shaped groove on the inner ring surface of the first turntable will generate a radial pressing force on the first slider, and then force the first slider to drive the traction arm to perform radial movement.

[0074] Similarly, the specific structural form of the above second inclined chute can be a second waist-shaped through hole 10b provided on the disk surface of the second turntable ring 8b and arranged at an acute angle to the radial direction of the second turntable ring 8b. The end of the pressing arm 5b is provided with a second slider 11b that can extend into the second waist-shaped through hole 10b, and the second slider 11b can slide along the second waist-shaped through hole 10b. When the second slider slides along the second waist-shaped through hole, the second waist-shaped through hole can generate pressure on the second slider. Since the second slider is arranged in an inclined manner at an acute angle to the radial direction, when the second turntable ring rotates, the second waist-shaped through hole can force the second slider to drive the pressing arm to perform radial linear movement. Of course, it can be understood that the inclination angles of the above second waist-shaped through holes in the relative radial direction should be the same to achieve synchronous and equal-length radial movement lengths. In addition, in order to avoid excessive relative sliding friction between the second slider and the inner wall of the second waist-shaped through hole and cause jamming, generally, the outer surface of the second slider can be designed to have a structure with a rolling sleeve, and the pure sliding structure between the second slider and the second waist-shaped through hole is changed into a rolling-sliding structure through the rolling sleeve, which can greatly reduce the frictional resistance and avoid the occurrence of jamming phenomena.

[0075] Here, it should be noted that the above arrangement of using the second waist-shaped through hole to form the second inclined chute is only a preferred example of the embodiment of the present invention. In actual application, the structure of the above second inclined chute can also be a second slope-shaped groove formed on the inner ring surface of the second turntable ring 8b and arranged at an acute angle to the radial direction of the second turntable ring 8b. The radially outer end of the pressing arm 5b is provided with a second slider that slidably cooperates with the second slope-shaped groove. By rotating the second turntable ring, the second slope-shaped groove on the inner ring surface of the second turntable will generate a radial pressing force on the second slider, and then force the second slider to drive the pressing arm to perform radial movement.

[0076] In some more specific embodiments, the specific structure of the above-mentioned tractor base 4a may include a first annular boss 12a coaxially arranged with the first circular through-hole and a first flange 13a provided at the bottom of the first annular boss 12a. The first guiding through-hole is provided on the first annular boss 12a. The first turntable ring 8a is sleeved on the first annular boss 12a, and the inner ring surface of the first turntable ring 8a is adapted to the outer circumferential surface of the first annular boss 12a. The bottom of the first turntable ring 8a is in contact with the top surface of the first flange 13a. By designing the tractor base in the above structural form, the tractor base can play a good role in fixing and supporting the first turntable ring. At the same time, it can also play a good limiting role on the inner ring surface of the first turntable ring through the outer circumferential surface of the first annular boss, so that the rotation of the first turntable ring is more stable.

[0077] Similarly, the specific structure of the above-mentioned tightening base 4b may include a second annular boss 12b coaxially arranged with the second circular through-hole and a second circular flange 13b provided at the bottom of the second annular boss 12b. The second guiding through-hole is provided on the second annular boss 12b. The second turntable ring 8b is sleeved on the second annular boss 12b, and the inner ring surface of the second turntable ring 8b is adapted to the outer circumferential surface of the second annular boss 12b. The bottom of the second turntable ring 8b is in contact with the top surface of the second circular flange 13b. By designing the pressing base in the above structural form, the pressing base can play a good role in fixing and supporting the second turntable ring. At the same time, it can also play a good limiting role on the inner ring surface of the second turntable ring through the outer circumferential surface of the second annular boss, so that the rotation of the second turntable ring is more stable.

[0078] In a further embodiment, in order to facilitate the connection between the first turntable ring 8a and the first driver 9a, generally, a first extension portion 14a for connecting the first driver 9a is provided on the circumferential wall of the first turntable ring 8a. The first driver 9a is a first telescopic rod, and the telescopic end of the first telescopic rod is hinged to the first extension portion 14a. Then, the rotation of the first turntable ring can be driven by the telescopic movement of the telescopic rod.

[0079] Similarly, in order to facilitate the connection between the second turntable ring 8b and the second driver 9b, generally, a second extension portion 14b for connecting the second driver 9b is provided on the circumferential wall of the second turntable ring 8b. The second driver 9b is a second telescopic rod, and the telescopic end of the second telescopic rod is hinged to the second extension portion 14b. Then, the rotation of the second turntable ring can be driven by the telescopic movement of the telescopic rod.

[0080] It should be noted that the specific structure of the above-mentioned telescopic rod may be a cylinder or oil cylinder-driven cylinder telescopic rod, or the structure of other telescopic mechanisms commonly used by those skilled in the art, such as the way of realizing telescopic movement by a lead screw mechanism, etc.

[0081] It should be noted that the above-described manner of using a telescopic rod as the first driver for the first turntable ring 8a is merely a preferred example of the embodiments of the present invention. In actual application, other driving methods can also be used to achieve rotational driving. For example, a first gear structure is provided on the circumferential wall of the first turntable ring 8a, and the first driver 9a is a first driving gear connected to a driving source, and the first driving gear meshes with the first gear structure. By rotating the first driving gear, the rotation of the first turntable ring can be driven. Or it can be other structural forms of drivers for driving a disc-shaped member commonly used by those skilled in the art, such as a manner in which a motor drives the first turntable ring to rotate through a belt or a chain, etc. No more specific limitations are made herein.

[0082] Similarly, the above-described manner of using a telescopic rod as the second driver for the second turntable ring 8b is merely a preferred example of the embodiments of the present invention. In actual application, other driving methods can also be used to achieve rotational driving. For example, a second gear structure is provided on the circumferential wall of the second turntable ring 8b, and the second driver 9b is a second driving gear connected to a driving source, and the second driving gear meshes with the second gear structure. By rotating the second driving gear, the rotation of the second turntable ring can be driven. Or it can be other structural forms of drivers for driving a disc-shaped member commonly used by those skilled in the art, such as a manner in which a motor drives the second turntable ring to rotate through a belt or a chain, etc. No more specific limitations are made herein.

[0083] In addition, the above-described traction mechanism may further include a workbench 15a for laying out the line stator flat. During actual operation, first place the line stator on the workbench, and then place the traction mechanism above the line stator from top to bottom, and insert the traction claws of the traction mechanism into the gap between the inner ring of its corresponding stator core and a single winding. Of course, it can be understood that the line stator can also be directly placed on the ground for operation. However, in order to avoid soiling the line stator, it is also necessary to lay a layer of protective paper or a protective plate on the ground each time an operation is performed. By placing the line stator on the above-described workbench for operation, it can effectively avoid the stator being contaminated by dust. On the other hand, by designing the workbench to a suitable height, it is more convenient for the operation of the traction mechanism.

[0084] It should be noted that the specific structure of the above-described workbench can be a structure of a flat table with a placement surface at the top, and it is generally made of iron material. It can also be designed as a structure of a trolley with a workbench surface at the top. A braking mechanism for preventing the traveling wheels from moving randomly is provided on the traveling wheels of the trolley, or it is equipped with an electric driving mechanism to drive the trolley structure.

[0085] In a further embodiment, the above-mentioned outer ring shaping mechanism further includes a support frame 15b, an upper pressing ring 16 and a lower pressing ring 17. Among them, the support frame 15b is used to support the lower end surface of the stator core 1; the lower surface of the upper pressing ring 16 is used to press-fit on the upper end surface of the wire coil located on the outer ring of the stator core 1 of the in-line stator; the upper surface of the lower pressing ring 17 is used to press-fit on the lower end surface of the wire coil located on the outer ring of the stator core 1 of the in-line stator, and the height of the pressing block 6b in the axial direction of the second circular through hole 3b does not exceed the axial height of the wire coil. By making the above-mentioned upper pressing ring and lower pressing ring fit with the upper and lower ends of the outer ring of the wire coil respectively, a good axial limiting effect can be exerted on the wire coil on the outer ring of the stator core, avoiding the problem that the wire coil spreads when the circumferentially arranged pressing blocks press on the circumferential surface of the wire coil. It should be noted that generally, in order to ensure the good limiting and leveling effects of the upper and lower pressing rings, the lower surface of the upper pressing ring should cover the entire top surface of the wire coil on the outer ring of the stator core, and the upper surface of the lower pressing ring should cover the entire bottom surface of the wire coil on the outer ring of the stator core. And in order to avoid interference between the pressing block and the upper and lower pressing rings, the height of the pressing block 6b in the axial direction of the second circular through hole 3b generally does not exceed the axial height of the wire coil, and the outer diameters of the upper and lower pressing rings are both larger than the maximum diameter of the wire coil. In addition, in order to make the installation and positioning of the upper and lower pressing rings more convenient, generally, the inner diameters of the upper and lower pressing rings are adapted to the outer diameter of the stator core. It should be noted that the so-called adaptation here means that the inner ring of the upper and lower pressing rings can just fit over the outer ring of the stator core. Additionally, it should be noted that the top surface of the support frame generally needs to be set as an annular support surface adapted to the lower surface of the stator core, and the formation method of this annular support surface can be a wooden annular surface provided on the top of the support frame, which can avoid scratching the stator core, or made of other materials commonly used by those skilled in the art, such as nylon or hard rubber, etc. Of course, it can also be made of a metal material, such as iron.

[0086] In a further embodiment, the above-mentioned pressing block 6b corresponds to each single winding 2 of the wire coil one by one. Because the irregularity of the outer ring of the wire coil before shaping is often caused by the inconsistent winding of each single winding, resulting in irregularity in the circumferential direction. By making the pressing block 6b correspond to each single winding 2 of the wire coil one by one, each pressing block can specifically shape the outer ring of each single winding, so that the final shaped size is more regular and flat.

[0087] In some more specific embodiments, the above-mentioned wire package shaping device further includes an inner ring shaping mechanism for shaping the inner ring wire package of the wire stator. The inner ring shaping mechanism includes a support platform 15c, an annular limiting platform 12c arranged on the support platform 15c, a plurality of expansion blocks 6c evenly arranged circumferentially inside the annular limiting platform 12c, and a third driving assembly 7c for driving the radial sliding expansion of the expansion blocks 6c. Among them, the tabletop of the support platform 15c is used to support the lower surface of the stator core 1 of the wire stator; the annular limiting platform 12c is used to abut against the lower end surface of the wire package located in the inner ring of the stator core 1; the radially outer end surface of the expansion block 6c is a first arc surface adapted to the circumferential inner surface of the wire package. In the actual application process, by sleeving the wire stator on the annular limiting platform 12c, the tabletop of the support platform 15c supports the lower surface of the stator core 1 of the wire stator, the top surface of the annular limiting platform abuts against the lower end surface of the wire package located in the inner ring of the stator core 1, and then the third driving assembly 7c is started to drive the radial sliding expansion of the expansion blocks 6c. Subsequently, the radially outer end surfaces of the expansion blocks 6c expand the circumferential inner surface of the wire package. Since the plurality of expansion blocks are evenly arranged circumferentially inside the annular limiting platform 12c, the inner ring of the wire package can be expanded and leveled, realizing the shaping of the inner ring of the wire package. It should be noted that generally, in order to ensure that the size after expansion does not rebound, the expansion blocks need to stay in this position for a period of time after moving in place.

[0088] In some more specific embodiments, a chute radially arranged and corresponding to the inner side of the annular limiting platform 12c is provided on the support platform 15c, and the bottom of the expansion block 6c is slidably matched with the chute. By providing the chute, the movement direction of each expansion block can be made more stable, and the sliding friction between the expansion block and the wire in the inner ring of the wire package is minimized.

[0089] It should be noted that the specific structure of the above-mentioned third driving assembly 7c can be in the form of a third telescopic arm, and a conical structure is provided at the end of the third telescopic arm. A second arc surface adapted to the conical structure is provided on the radially inner end surface of the expansion block 6c. In this way, through the telescoping of the third telescopic arm, the conical structure generates a radial pushing force on the second arc surface of the expansion block, and then the circumferential expansion action of the expansion block is realized. Of course, it can be understood that the driving mode of the above-mentioned third telescopic arm is only a preferred example of the third driving assembly in the embodiments of the present invention. In the actual application process, other circumferential expansion driving structures commonly used by those skilled in the art can also be adopted. For example, the third driving assembly is a disc-shaped driving member, a planar thread is provided on the lower surface of the disc-shaped driving member, and a thread structure adapted to the planar thread is provided on the top of the expansion block. The circumferential expansion action of the expansion block can be realized by rotating the disc-shaped driving member.

[0090] Generally speaking, the above-mentioned inner ring shaping mechanism may further include an inner positioning pressing ring 18, which is used to press on the upper surface of the wire coil located in the inner ring of the stator core 1, and the size of the inner ring surface of the inner positioning pressing ring 18 is the same as the pre-shaping size of the inner ring of the wire coil. By means of the above-mentioned inner positioning pressing ring, it is possible to avoid the phenomenon that the top of the wire coil located in the inner ring of the stator core becomes loose during the inner ring shaping process; and the inner ring surface of the inner positioning pressing ring 18 can well position the termination position of the expansion movement of the expansion block, thereby improving work efficiency.

[0091] In addition, in order to prevent the outer ring of the wire coil from deforming again when transferring to the inner ring shaping process after the outer ring shaping of the wire coil is completed, the above-mentioned inner ring shaping mechanism further includes an outer positioning ring sleeve 19, which is used for shaping the outer positioning ring sleeve 19 of the wire coil located in the outer ring of the stator core 1, and the outer positioning ring sleeve 19 includes a first pressing ring surface adapted to the top surface of the wire coil located in the outer ring of the stator core 1 and a second pressing ring surface used for adapting to the outer circumferential surface of the wire coil located in the outer ring of the stator core 1. By fitting the first pressing ring surface to the top surface of the wire coil located in the outer ring of the stator core 1 and the second pressing ring surface to the outer circumferential surface of the wire coil located in the outer ring of the stator core 1, the wire coil located in the outer ring of the stator core can be shaped, avoiding deformation again.

[0092] In addition, the present invention also provides a method for shaping the wire coil of a wire stator, which adopts the wire stator wire coil shaping device described in any of the above solutions, and specifically includes the steps:

[0093] Step S1: Insert the respective traction claws 6 of the traction mechanism into the gaps between the individual windings 2 on the wire stator and the inner ring of the stator core 1, and drive the first drive assembly to apply a traction force in the axial direction of the wire stator to each corresponding individual winding 2 by the respective traction claws 6;

[0094] Step S2: Fit the outer ring shaping mechanism as a whole over the outer ring of the wire coil of the wire stator, and drive the second drive assembly to make the pressing block abut against and press the circumferential outer surface of the wire coil located in the outer ring of the stator core 1 of the wire stator to a preset position;

[0095] It should be noted that the above-mentioned Step S1 and Step S2 are executed step by step or synchronously.

[0096] In a further embodiment, after the outer ring shaping of the wire coil is completed, it further includes step S3: shaping the inner ring wire coil of the wire stator through an inner ring shaping mechanism. The specific operation process is as follows: by sleeving the wire stator on the circular limiting platform 12c, the tabletop of the support platform 15c supports the lower surface of the stator core 1 of the wire stator, the top surface of the circular limiting platform abuts against the lower end surface of the wire coil located in the inner ring of the stator core 1, and then the third driving component 7c is started to drive the expansion block 6c to radially slide and expand, and then the outer radial end surface of the expansion block 6c expands the circumferential inner surface of the wire coil. Since multiple expansion blocks are circumferentially and evenly arranged inside the circular limiting platform 12c, the inner ring of the wire coil can be expanded and flattened, realizing the shaping of the inner ring of the wire coil. It should be noted that generally, in order to ensure that the size after expansion does not rebound, the expansion block needs to stay in this position for a period of time after moving in place.

[0097] Since the wire coil shaping device of the above-mentioned wire stator has the above technical effects, and the wire coil shaping method of the wire stator adopting the above wire coil shaping device inherits the core idea of the above wire coil shaping method of the wire stator, it should also have the corresponding technical effects, which will not be elaborated here.

[0098] The above has introduced in detail the wire coil shaping device and method provided by the present invention. It should be noted that each embodiment in this specification is described in a progressive manner, and the key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0099] It should also be noted that in this article, terms such as "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that an article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such an article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the article or device including the above element.

[0100] Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the core idea of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
