Description

Technical Field

[0001] The present invention relates to the technical field of stator processing, and particularly relates to a wire winding device for stator processing. Background Art

[0002] The stator is one of the core components in an electric motor. The stator cooperates with the rotating rotor to jointly achieve the mutual conversion of electrical energy and mechanical energy. According to the different directions of the stator slot openings, the stator is divided into an outer-wound stator and an inner-wound stator. The outer-wound stator usually adopts the flying fork wire winding method, where the wire enters the slot opening from the outside, with a fast wire winding speed and high production efficiency. The outer-wound stator is suitable for products such as model airplanes, plant protection machines, drones, fascia guns, twist cars, and electric vehicles. The inner-wound stator often adopts the needle-type wire winding method. The stator slot opening faces inward, and the outside of the skeleton is closed. Through the up, down, left, and right movement of the needle rod, the wire winding process is completed in cooperation with the mold. The inner-wound stator is more suitable for products such as household appliances, medical devices, water pumps, stepping servos, and power tools.

[0003] Chinese Patent with the authorization announcement number CN220067174U discloses a stator wire winding clamping device. The stator wire winding clamping device includes: a base, a driving mechanism, and a clamping assembly. The base is installed on the wire winding device, the stator is sleeved outside the base, the driving mechanism is installed on the base and has a movable end, and a plurality of clamping assemblies are installed on the base. The clamping assembly includes a first support rod, a clamping block, and a second support rod arranged in sequence from top to bottom. The upper end of the first support rod is hinged to the movable end, the lower end of the second support rod is hinged to the base, and the lower end of the first support rod and the upper end of the second support rod are both hinged to the clamping block.

[0004] When the above-mentioned stator wire winding clamping device is used, the base of the stator wire winding clamping device is fixed on the indexing servo motor of the flying fork wire winding device. The driving mechanism is used to control the movable end to rise, and drive the first support rod and the second support rod in the clamping assembly to rise. At the same time, since the clamping block is respectively hinged to the lower end of the first support rod and the upper end of the second support rod, the clamping block moves away from the inner wall of the stator. After the stator is sleeved outside the base, the driving mechanism is used to control the movable end to descend again, and drive the first support rod and the second support rod to descend, so that the clamping block moves towards the inner wall of the stator until each clamping block is in close contact with the inner wall of the stator and fixes the stator.

[0005] However, this clamping method is only applicable to externally wound stators. For internally wound stators, since their stator slots face inward, when winding the wire, the winding equipment needs to be inserted into the stator, and then the winding is wound around the stator. To avoid the clamping assembly from obstructing the winding of the stator by the winding equipment, it is impossible to support the stator from the inside. The clamping equipment applicable to internally wound stators usually clamps the stator from the outside, but this clamping equipment is not applicable to externally wound stators. Therefore, a new type of wire winding device for stator processing is needed, which can meet the wire winding requirements for both internally wound stators and externally wound stators. Summary of the Invention

[0006] The present invention provides a wire winding device for stator processing, aiming to solve the problem in the related technology that the clamping assembly can only clamp internally wound stators or externally wound stators, resulting in low versatility.

[0007] The wire winding device for stator processing of the present invention includes: a clamping system and a wire winding system; The clamping system is used for clamping the stator, and the wire winding system is used for winding the stator; The clamping system includes a workbench, a positioning ring, positioning rods, and positioning columns. The positioning columns and the positioning rods are both arranged on the workbench, and the positioning ring is coaxially distributed with the positioning columns. A plurality of the positioning rods are located between the positioning columns and the positioning ring and are circumferentially spaced along the positioning columns. A support seat is rotatably fitted at the bottom of each positioning rod. A rotating assembly is provided inside the workbench, and the rotating assembly is used to drive the positioning rods to rotate. A first elastic member and a second elastic member are provided on the support seat. The first elastic member can abut against the positioning ring, and the second elastic member can abut against the positioning column.

[0008] Beneficial effects: When clamping an externally wound stator, the inner hole of the externally wound stator is sleeved from top to bottom outside the cylindrical structure formed by a plurality of positioning rods. During this process, the positioning rods will move towards the positioning columns, so that the second elastic member is compressed. The elastic force of the second elastic member will push the positioning rods to closely adhere to the inner hole wall of the externally wound stator. The combined action of a plurality of positioning rods can thus support the externally wound stator from the inside and achieve the fixation of the externally wound stator. When clamping an internally wound stator, the internally wound stator is placed inside the cylindrical structure formed by a plurality of positioning rods. During this process, the positioning rods will move towards the positioning ring, so that the first elastic member is compressed. The elastic force of the first elastic member will push the positioning rods to closely adhere to the outer side wall of the internally wound stator. The combined action of a plurality of positioning rods can thus clamp the internally wound stator from the outside and achieve the fixation of the internally wound stator.

[0009] Preferably, a first guide rod and a second guide rod are respectively provided on the support base. The first elastic member is sleeved on the first guide rod, and the second elastic member is sleeved on the second guide rod. The first guide rod extends outwards and is in sliding fit with the positioning ring. The second guide rod extends inwards and is in sliding fit with the positioning column.

[0010] The effect is that the arrangement of the first guide rod and the second guide rod can prevent the positioning rod and the support base from shifting when approaching the positioning column or the positioning ring.

[0011] Preferably, the positioning rod is a broken-line rod, which includes a first rod and a second rod. The first rod is vertically distributed, and the second rod is obliquely distributed. The bottom end of the second rod is connected to the top end of the first rod. The top ends of multiple second rods abut against each other, so as to form a conical structure. The top ends of multiple second rods are away from each other, so as to form a flared structure.

[0012] The effect is that when clamping an outer-wound stator, the inner hole of the stator of the outer-wound stator is sleeved on the conical structure formed by the second rods. The outer-wound stator gradually moves downwards from the top end of the conical structure formed by the second rods. When the inner hole wall of the stator of the outer-wound stator contacts the second rods, the gravity of the outer-wound stator will push the second rods to move inwards until the first rod abuts against the inner hole wall of the stator of the outer-wound stator. When clamping an inner-wound stator, the positioning rod is rotated by the rotating assembly, so that a flared structure is formed between multiple second rods. The inner-wound stator is placed on the flared structure, and the gravity of the inner-wound stator will push the second rods to move outwards until the first rod contacts the outer side wall of the inner-wound stator.

[0013] Preferably, the rotating assembly includes a first driving member, a rotating disk, a rotating rod and an adjusting plate. The rotating disk is arranged below the workbench. The first driving member is used to drive the rotating disk to rotate. Multiple rotating rods are spaced along the circumference of the rotating disk. A slider is slidably fitted on each rotating rod. A third elastic member is provided between the slider and the end of the rotating rod. The adjusting plate is arranged on the slider. The first rod passes through the support base and extends downwards. A rotating gear is provided on the first rod. The adjusting plate is located outside the rotating gear and can mesh with the rotating gear.

[0014] Preferably, the adjusting plate is an arc-shaped structure. Multiple adjusting plates are connected end to end to form an annular structure.

[0015] The effect is that the adjusting plate is set as an arc-shaped structure, which can avoid the moving interference of the rotating gear on the adjusting plate when the rotating assembly rotates.

[0016] Preferably, a limiting block is provided at the outer end of the rotating rod, and the limiting block can abut against the slider.

[0017] Its effect is that setting the limit block can limit the movement range of the slider and prevent the slider from detaching from the rotating rod.

[0018] Preferably, a fixing component is further provided. The fixing component includes a second driving member, a lifting seat, and a connecting plate. The second driving member is used to drive the lifting seat to move up and down. A plurality of the connecting plates are distributed at intervals along the circumferential side of the lifting seat. One end of the connecting plate is hinged to the first guiding rod, and the other end thereof is hinged to the lifting seat.

[0019] Its effect is that when clamping an outer-wound stator, the second driving member drives the lifting seat to move downward. The lifting seat pulls the connecting plate, and the connecting plate applies an outward pulling force to the first guiding rod. The first guiding rod transmits the pulling force to the supporting seat and the positioning rod, so that the positioning rod applies an outward pushing force to the outer-wound stator. Each positioning rod applies an outward pushing force to the outer-wound stator, thereby further propping up the outer-wound stator and fixing the outer-wound stator on the workbench to prevent the outer-wound stator from shaking during winding. Similarly, when clamping an inner-wound stator, the second driving member drives the lifting seat to move upward. The lifting seat pushes the connecting plate, and the connecting plate applies an inward pushing force to the first guiding rod. The first guiding rod transmits the pushing force to the supporting seat and the positioning rod, so that the positioning rod applies an inward pushing force to the inner-wound stator, further clamping the inner-wound stator and fixing the outer-wound stator on the workbench.

[0020] Preferably, a buffer block is further provided between the lifting seat and the second driving member. The buffer block is connected to the output end of the second driving member. The lifting seat is slidably engaged with the buffer block. A first limiting ring and a second limiting ring are respectively provided at the top end and the bottom end of the buffer block. The first limiting ring and the second limiting ring can abut against the lifting seat.

[0021] Its effect is that setting the buffer block enables the lifting seat to slide up and down along the buffer block, avoiding the lifting seat hindering the inward or outward movement of the positioning rod when sleeving the inner-wound stator or the outer-wound stator on the positioning rod, and further avoiding the inability to sleeve the inner-wound stator or the outer-wound stator on the positioning rod.

[0022] Preferably, the second guiding rod is a telescopic rod. One end of the second guiding rod is connected to the supporting seat, and the other end thereof extends into the positioning column and is connected to the positioning column.

[0023] Preferably, the winding system includes a robotic arm and a needle rod. The needle rod is provided on the robotic arm, and an enameled wire is wound around the needle rod.

[0024] Adopting the above technical solutions, the beneficial effects of the present invention are as follows: For the winding device for stator processing according to the present invention, when clamping an externally wound stator, the inner hole of the externally wound stator is sleeved from top to bottom outside the cylindrical structure composed of a plurality of positioning rods. During this process, the positioning rods will move towards the positioning posts, so that the second elastic member is compressed. The elastic force of the second elastic member will push the positioning rods against the inner hole wall of the externally wound stator. The combined action of the plurality of positioning rods can thus support the externally wound stator from the inside to fix the externally wound stator. When clamping an internally wound stator, the internally wound stator is placed inside the cylindrical structure composed of a plurality of positioning rods. During this process, the positioning rods will move towards the positioning ring, so that the first elastic member is compressed. The elastic force of the first elastic member will push the positioning rods against the outer side wall of the internally wound stator. The combined action of the plurality of positioning rods can thus clamp the internally wound stator from the outside to fix the internally wound stator. The winding device for stator processing of the present invention can be applied to both externally wound stators and internally wound stators, and has high versatility.

[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0038] The winding device for stator processing of the present invention includes: a clamping system and a winding system, wherein the clamping system is used to fix the stator, and the winding system is used to wind the enameled wire around the stator.

[0039] Specifically, the winding system is a needle-type winding device in the conventional technology, which includes a robotic arm and a needle rod. The needle rod is fixedly arranged on the robotic arm, and the robotic arm is used to drive the needle rod to move freely in space, and the enameled wire is wound around the needle rod.

[0040] As Figures 1 to 4As shown in the figure, the clamping system includes a workbench 1, a positioning ring 2, positioning rods 3, and positioning columns 4. The workbench 1 is set on the ground and is hollow inside. The positioning ring 2 has a regular octagon structure and is fixedly set at the top of the workbench 1 and coaxially distributed with the workbench 1. The positioning column 4 is a regular octagonal prism and corresponds to the positioning ring 2. The positioning column 4 is fixedly set on the workbench 1 and coaxially distributed with the workbench 1, so that an annular space is formed between the positioning column 4 and the positioning ring 2. There are eight positioning rods 3, and the number of the positioning rods 3 is the same as the number of the side walls of the positioning column 4 and the positioning ring 2. The eight positioning rods 3 are all located in the annular space between the positioning column 4 and the positioning ring 2 and are evenly spaced along the circumferential direction of the positioning column 4. The positioning rod 3 includes a first rod 31 and a second rod 32. The first rod 31 is vertically distributed, and the second rod 32 is obliquely distributed. The bottom end of the second rod 32 is fixedly connected to the top end of the first rod 31. A broken-line structure is formed between the first rod 31 and the second rod 32. The tops of multiple second rods 32 abut against each other, so that a conical structure can be formed. When the positioning rod 3 rotates 180 degrees, the tops of multiple second rods 32 move away from each other, and then a trumpet-shaped structure can be formed. A rubber sleeve is also sleeved on the first rod 31. The rubber sleeve is used to increase the friction coefficient of the first rod 31, so as to increase the friction force between the first rod 31 and the stator and prevent the stator from moving relative to the first rod 31.

[0041] A support seat is also provided at the lower region of each positioning rod 3. First guide rods 8 and second guide rods 9 are respectively provided on both sides of the bottom of the support seat. The first guide rod 8 is a straight rod. The inner end of the first guide rod 8 is fixedly connected to the outer side wall of the support seat. The outer end of the first guide rod 8 passes through the positioning ring 2 and extends outward. The first guide rod 8 is in sliding fit with the positioning ring 2. The second guide rod 9 is a telescopic rod. The outer end of the second guide rod 9 is fixedly connected to the inner side wall of the support seat. The inner end of the second guide rod 9 extends into the positioning column 4 and is fixedly connected to the positioning column 4. First elastic members 6 and second elastic members 7 are also provided on the inner and outer sides of the support seat. The first elastic member 6 is sleeved on the first guide rod 8. The inner end of the first elastic member 6 is fixedly connected to the outer side wall of the support seat. The outer end of the first elastic member 6 can abut against the inner side wall of the positioning ring 2. The second elastic member 7 is sleeved on the second guide rod 9. The outer end of the second elastic member 7 is fixedly connected to the inner side wall of the support seat. The inner end of the second elastic member 7 can abut against the positioning column 4.

[0042] When clamping the outer-wound stator 100, the tops of the multiple second rods 32 abut against each other, so as to form a conical structure. The inner hole of the outer-wound stator 100 is sleeved from top to bottom on the conical structure formed by the eight positioning rods 3. Since the diameter of the cylindrical structure formed by the eight positioning rods 3 is greater than the diameter of the inner hole of the outer-wound stator 100, during the process of the outer-wound stator 100 moving downward along the conical structure, the outer-wound stator 100 will abut against the second rod 32 and push the positioning rod 3 to move inward. The second elastic member 7 is compressed. When the first rod 31 abuts against the inner hole wall of the outer-wound stator 100, the positioning rod 3 stops moving inward. The outer-wound stator 100 moves downward until it abuts against the top surface of the support table 5. The support table 5 can support the outer-wound stator 100. At this time, the second elastic member 7 applies an outward elastic force to the positioning rod 3, so that the positioning rod 3 supports the outer-wound stator 100 from the inside.

[0043] When clamping the inner-wound stator 200, rotate the positioning rod 3, so that the tops of the multiple second rods 32 move away from each other and form a flared structure. The inner-wound stator 200 is placed on the flared structure from top to bottom. Since the diameter of the cylindrical structure formed by the eight positioning rods 3 is smaller than the diameter of the inner-wound stator 200, the outer side wall of the inner-wound stator 200 will abut against the second rod 32 and push the positioning rod 3 to move outward. The first elastic member 6 is compressed. When the first rod 31 abuts against the outer side wall of the inner-wound stator 200, the positioning rod 3 stops moving outward. The inner-wound stator 200 moves downward until it abuts against the top surface of the support table 5. The support table 5 can support the inner-wound stator 200. At this time, the first elastic member 6 applies an inward elastic force to the positioning rod, so that the positioning rod 3 clamps the inner-wound stator 200 from the outside.

[0044] Such as Figure 2 、 Figures 4 to 6As shown in the figure, a rotating assembly 11 is provided inside the workbench 1. The rotating assembly 11 includes a first driving member 111, a rotating disk 112, a rotating rod 113, and an adjusting plate 117. A fixed seat 10 is provided inside the workbench 1. The fixed seat 10 is located directly below the positioning column 4 and the positioning ring 2. The top end of the fixed seat 10 is fixedly connected to the inner side wall of the workbench 1. The rotating disk 112 is rotatably fitted on the top surface of the fixed seat 10. The rotating disk 112 is coaxially distributed with the positioning column 4. The rotating disk 112 is located directly below the positioning column 4 and is spaced from the positioning column 4 vertically. The first driving member 111 is fixedly arranged on the fixed seat 10. The first driving member 111 is a motor, and its output end is fixedly connected to the rotating disk 112. The first driving member 111 is used to drive the rotating disk 112 to rotate. There are eight rotating rods 113. The eight rotating rods 113 are evenly spaced along the circumference of the rotating disk 112. The number of rotating rods 113 is the same as the number of positioning rods 3. The inner end of the rotating rod 113 is fixedly connected to the rotating disk 112. A limiting block 116 is fixedly arranged at the outer end of the rotating rod 113. A slider 114 is slidably fitted on the rotating rod 113. The slider 114 and the limiting block 116 are elastically connected by a third elastic member 115. The third elastic member 115 is a spring. One end of it is fixedly connected to the slider 114, and the other end is fixedly connected to the limiting block 116. The slider 114 can slide along the rotating rod 113. The adjusting plate 117 is fixedly arranged on the slider 114. The adjusting plate 117 is an arc-shaped plate. Tooth grooves are provided on the inner side wall of the adjusting plate 117. There are eight first grooves 101 on the workbench 1. The first grooves 101 are located between the positioning column 4 and the positioning rod 3. The eight first grooves 101 are evenly spaced along the circumference of the positioning column 4, thus forming a radial structure. Each first groove 101 corresponds to a positioning rod 3. The bottom end of the first rod 31 can pass through the top surface of the workbench 1 through the first groove 101 and extend into the workbench 1. A rotating gear 118 is fixedly arranged at the bottom end of the first rod 31. The inner side wall of the adjusting plate 117 abuts against the rotating gear 118. The third elastic member 115 is always in a compressed state, thereby applying an inward thrust to the slider 114, and further ensuring that the adjusting plate 117 always fits against the rotating gear 118. The adjusting plate 117 meshes with the rotating gear 118 through the tooth grooves on its inner side wall.

[0045] When the positioning rod 3 moves outward along the first guide rod 8 in the first groove 101, the positioning rod 3 applies an outward thrust to the adjusting plate 117 through the rotating gear 118, so that the slider 114 moves outward against the elastic force of the third elastic member 115, and the third elastic member 115 is compressed. When the positioning rod 3 moves inward along the second guide rod 9 in the first groove 101, the third elastic member 115 releases the elastic force and expands. The third elastic member 115 pushes the slider 114 and the adjusting plate 117 to move inward, and makes the adjusting plate 117 always mesh with the rotating gear 118. When the positioning rod 3 moves inward to the limit, the plurality of adjusting plates 117 are in contact with each other to form an annular structure. At this time, the first driving member 111 drives the rotating disk 112 to rotate, thereby driving the rotating rod 113 to rotate, and further making the annular structure formed by the adjusting plates 117 rotate. During the rotation of the adjusting plate 117, the adjusting plate 117 will drive the positioning rod 3 to rotate through the rotating gear 118. When the adjusting plate 117 rotates 45 degrees, the rotating gear 118 rotates 180 degrees.

[0046] As Figure 2 , Figures 7 to 9 shown, a fixing assembly 12 is further provided in the workbench 1. The fixing assembly 12 includes a second driving member 121, a lifting seat 122 and a connecting plate 123. The second driving member 121 is fixedly arranged at the bottom of the fixing seat 10. The second driving member 121 is a hydraulic cylinder. The output end of the second driving member 121 is fixedly connected with a buffer block 124. The second driving member 121 can drive the buffer block 124 to move up and down. A first limiting ring 1241 is arranged at the top end of the buffer block 124, and a second limiting ring 1242 is arranged at the bottom end of the buffer block 124. The lifting seat 122 is slidably fitted on the buffer block 124 and is located between the first limiting ring 1241 and the second limiting ring 1242. The lifting seat 122 can move up and down along the axis of the buffer block 124. When the lifting seat 122 moves upward to the limit, the lifting seat 122 abuts against the first limiting ring 1241. When the lifting seat 122 moves downward to the limit, the lifting seat 122 abuts against the second limiting ring 1242. There are eight connecting plates 123. The number of the connecting plates 123 is the same as the number of the positioning rods 3. The eight connecting plates 123 are evenly spaced along the circumferential direction of the lifting seat 122. One end of the connecting plate 123 is hinged to the lifting seat 122, and the other end is hinged to the outer end of the corresponding first guide rod 8. Eight second grooves 102 are arranged on the top surface of the workbench 1. The eight second grooves 102 are evenly spaced along the circumferential direction of the positioning ring 2. The outer end of the first guide rod 8 extends into the second groove 102 and can move along the second groove 102.

[0047] When clamping the outer-wound stator 100, the second driving member 121 drives the buffer block 124 to move downward, so that the buffer block 124 moves downward relative to the lifting seat 122. When the first limiting ring 1241 abuts against the lifting seat 122, the first limiting ring 1241 will pull the lifting seat 122 to move downward synchronously. The downward movement of the lifting seat 122 will pull the connecting plate 123, and cause the connecting plate 123 to apply an outward pulling force to the first guide rod 8. The pulling force is transmitted to the support seat and the first rod 31, so as to apply an outward pulling force to the first rod 31, further causing the first rod 31 to support the outer-wound stator 100 from the inside to the outside, realizing the fixation of the outer-wound stator 100 and preventing the outer-wound stator 100 from moving during the winding process. Similarly, when clamping the inner-wound stator 200, the second driving member 121 drives the buffer block 124 to move upward, so that the buffer block 124 moves upward relative to the lifting seat 122. When the second limiting ring 1242 abuts against the lifting seat 122, the second limiting ring 1242 will push the lifting seat 122 to move upward synchronously. The upward movement of the lifting seat 122 will push the connecting plate 123, and cause the connecting plate 123 to apply an inward pushing force to the first guide rod 8. The pushing force is transmitted to the support seat and the first rod 31, so as to apply an inward pushing force to the first rod 31, further causing the first rod 31 to clamp the inner-wound stator 200 from the outside to the inside, realizing the fixation of the inner-wound stator 200 and preventing the inner-wound stator 200 from moving during the winding process.

[0048] The implementation principle of the winding device for stator processing in the embodiment of the present invention is as follows: As Figure 10As shown, when winding the outer-wound stator 100, the tops of multiple second rods 32 abut against each other, so as to form a conical structure. The inner hole of the outer-wound stator 100 is sleeved on the conical structure formed by eight positioning rods 3 from top to bottom. Since the diameter of the cylindrical structure formed by the eight positioning rods 3 is larger than the diameter of the inner hole of the outer-wound stator 100, during the process of the outer-wound stator 100 moving downward along the conical structure, the outer-wound stator 100 will abut against the second rod 32 and push the positioning rod 3 to move inward, and the second elastic member 7 is compressed. When the first rod 31 abuts against the inner hole wall of the outer-wound stator 100, the positioning rod 3 stops moving inward, and the outer-wound stator 100 moves downward until it abuts against the top surface of the support platform 5. The support platform 5 can support the outer-wound stator 100. At this time, the second elastic member 7 exerts an outward elastic force on the positioning rod 3, so that the positioning rod 3 supports the outer-wound stator 100 from the inside. The second driving member 121 drives the buffer block 124 to move downward, so that the buffer block 124 moves downward relative to the lifting seat 122. When the first limiting ring 1241 abuts against the lifting seat 122, the first limiting ring 1241 will pull the lifting seat 122 to move downward synchronously. The downward movement of the lifting seat 122 will pull the connecting plate 123 and make the connecting plate 123 exert an outward pulling force on the first guide rod 8. The pulling force is transmitted to the support seat and the first rod 31, so as to exert an outward pulling force on the first rod 31, and further make the first rod 31 support the outer-wound stator 100 from the inside to the outside, realizing the fixation of the outer-wound stator 100 and preventing the outer-wound stator 100 from moving during the winding process. The robotic arm moves the needle bar to the side of the outer wall of the outer-wound stator 100 and winds the enameled wire around the outer-wound stator 100 through the needle bar.

[0049] As Figure 11As shown in the figure, when winding the inner-wound stator 200, the positioning rod 3 is first rotated by the rotating assembly 11, so that the tops of the plurality of second rods 32 move away from each other and form a horn-shaped structure. The inner-wound stator 200 is placed on the horn-shaped structure from top to bottom. Since the diameter of the cylindrical structure formed by the eight positioning rods 3 is smaller than the diameter of the inner-wound stator 200, the outer side wall of the inner-wound stator 200 will abut against the second rod 32 and push the positioning rod 3 to move outward. The first elastic member 6 is compressed. When the first rod 31 abuts against the outer side wall of the inner-wound stator 200, the positioning rod 3 stops moving outward. The inner-wound stator 200 moves downward until it abuts against the top surface of the support table 5. The support table 5 can support the inner-wound stator 200. At this time, the first elastic member 6 exerts an inward elastic force on the positioning rod, so that the positioning rod 3 clamps the inner-wound stator 200 from the outside. The second driving member 121 drives the buffer block 124 to move upward, so that the buffer block 124 moves upward relative to the lifting seat 122. When the second limiting ring 1242 abuts against the lifting seat 122, the second limiting ring 1242 will push the lifting seat 122 to move upward synchronously. The upward movement of the lifting seat 122 will push the connecting plate 123 and cause the connecting plate 123 to exert an inward thrust on the first guide rod 8. The thrust is transmitted to the support seat and the first rod 31, so as to exert an inward thrust on the first rod 31, further causing the first rod 31 to clamp the inner-wound stator 200 from the outside to inside, realizing the fixation of the inner-wound stator 200 and preventing the inner-wound stator 200 from moving during the winding process.
