Description

Technical Field

[0001] The invention relates to the technical field of stator winding equipment, and in particular to a winding and wire drawing integrated machine for a motor stator. Background Art

[0002] The stator is divided into an outer-wound stator and an inner-wound stator according to the direction of the slot. The outer-wound stator usually adopts the flying fork winding method. The wire enters the slot from the outside. It has a fast speed and high efficiency. It is a relatively economical winding method. Most ordinary stators are wound in this way.

[0003] The patent with publication number CN218888362U discloses an external stator winding device, which sleeves the stator to be wound on the stator placement disk, drives the first threaded rod to rotate by rotating the first rotating handle, and the first threaded rod drives the movable clamping plate to slide, thereby cooperating with the fixed clamping plate to clamp the stator on the stator placement disk, and then adjusts the position of the movable frame according to the diameter of the stator, and drives the second threaded rod to rotate by the second rotating handle, so that the movable frame slides on the equipment base, so that the rotating shaft can reach an appropriate position, and then the wire is inserted into the lead tube for guidance, and the second motor is started to drive the rotating shaft to rotate, and the lead tube on the rotating shaft will rotate accordingly, so that the wire in the lead tube is wound on the stator. The outer stator winding device is used to wrap around the stator and complete the winding of the stator. When the angle of the stator needs to be adjusted during the winding process, the first motor can be started to use the connecting belt to drive the stator placement disk to rotate. By setting up a fixed frame, a first threaded rod, a movable clamping plate, a movable frame, a second threaded rod, a lead tube and an arc-shaped baffle and other components, the outer stator winding device can stably lead the wire during use and complete the winding of the stator with the cooperation of the arc-shaped baffle. At the same time, during the stator winding process of the outer stator winding device, the stator can be stably clamped, and the distance between the rotating shaft and the stator can be adjusted according to the diameter of the stator, thereby effectively improving the use efficiency and practicality of the outer stator winding device.

[0004] Although the copper wire can be stably wound on the stator in the above process, the copper wire needs to be wound on the arc baffle before being wound on the stator. As the copper wire is tightened, the copper wire and the arc baffle slide relative to each other, causing the copper wire wound on the arc baffle to slide onto the stator. Since the winding speed of the outer winding stator is fast, the copper wire will rub against the arc baffle during the rapid tightening of the copper wire, which may cause scratches on the copper wire and affect its performance.

[0017] 1. The present invention is provided with a first reciprocating mechanism, a wire guide tube, a swing mechanism, a central axis and a rotating mechanism. The rotating mechanism drives the central axis to rotate, and the central axis drives the outer winding stator to rotate, ensuring that the middle surface between two adjacent stator slots forms a vertical relationship with the frame plate, providing precise positioning for subsequent copper wire winding. The cooperation of the swing mechanism and the moving block enables the wire guide tube to flexibly move between two adjacent stator slots. At the same time, the first reciprocating mechanism drives the moving block to reciprocate along the guide slide bar, guiding the copper wire to accurately embed into the stator slot, ensuring the uniform distribution and tight winding of the copper wire, thereby realizing that the copper wire is directly wound on the outer winding stator, avoiding friction between the copper wire and the guide component.

[0018] 2. The present invention is provided with a guide assembly, an abutment assembly and a first linear drive.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] The staff puts the outer winding stator to be wound on the placement end of the central shaft 4, and uses the fixing mechanism 6 to fix it on the central shaft 4, ensuring the stability and accuracy of the stator during the winding process. Then the rotating mechanism 7 starts to work, and the second rotating driver 73 drives the central shaft 4 to rotate through the transmission belt 74, and the central shaft 4 drives the outer winding stator to rotate until the middle surface of two adjacent stator slots forms a vertical relationship with the frame plate, and the two swinging mechanisms 3 simultaneously apply force to both sides of the moving block 12, and the moving block 12 drives the guide slide bar 11 to rotate around the axis of the central shaft 4. When the moving path of the lead tube 2 overlaps with one of the above-mentioned adjacent stator slots, the moving block 12 moves from one end of the guide slide bar 11 to the other end, and the lead tube 2 guides the copper wire from one end of the outer winding stator to the other end, and at the same time embeds the copper wire into the stator slot, and the two swinging mechanisms 3 drive the moving block 12 to move in the opposite direction again, so that the moving path of the lead tube 2 overlaps with another adjacent stator slot. The openings overlap, and the moving block 12 drives the lead tube 2 to reset again, completing the winding of the copper wire on the outer winding stator for one circle, repeating many times until the copper wire forms multiple layers of tight winding on the outer winding stator. At the same time, the mounting block 71 reciprocates along the second guide column 72, and the mounting block 71 drives the central axis 4 and the outer winding stator fixed thereon to move together, so that the outer winding stator continuously changes its position along the diameter direction in its middle surface, changes the distance between the end of the lead tube 2 and the center axis of the outer winding stator, and ensures that the copper wire can be wound on the outer winding stator layer by layer and evenly. When the copper wire winding work on a stator is completed, the rotating mechanism 7 drives the central axis 4 to rotate again, so that the middle surface of the next two adjacent stator slots forms a vertical relationship with the frame plate. Subsequently, the winding mechanism continues to work according to the above process until the outer winding stator is full of copper wire, thereby realizing that the copper wire is directly wound on the outer winding stator, avoiding friction between the copper wire and the guide component.

[0038] Reference Figure 4 and Figure 5 As shown: the first reciprocating mechanism 1 also includes two guide assemblies 13; the two guide assemblies 13 are respectively arranged at the two ends of the guide slide 11, and the guide slide 11 is connected to the guide assemblies 13, the guide slide 11 includes a guide block 131, the guide block 131 is provided with an arc groove, an arc guide rod 132 is arranged in the arc groove, and the axis of the arc guide rod 132 is colinear with the axis of the central axis 4; the swing mechanism 3 includes an abutment assembly 31, the abutment assembly 31 is arranged on one side of the moving block 12, a first linear driver 32 is arranged on one side of the abutment assembly 31, and the output end of the first linear driver 32 is hinged to the abutment assembly 31.

[0039] When it is necessary to adjust the travel path of the moving block 12, the two swing mechanisms 3 work simultaneously, and the first linear driver 32 located in front of the swinging direction of the moving block 12 reduces the force on the moving block 12, while the first linear driver 32 located behind the swinging direction increases the force, so that the forces on both sides of the moving block 12 are uneven. Under the push of the first linear driver 32 with a larger force, the moving block 12 transmits the force to the guide slide bar 11, and the guide slide bar 11 rotates along the arc-shaped guide bar 132 around the axis of the central axis 4, thereby ensuring the stability of the guide slide bar 11 during the rotation process.

[0040] Reference Figure 5 and Figure 6 As shown: the abutment assembly 31 includes a wheel frame 311 and a plurality of rollers 312; the middle portion of the wheel frame 311 is hinged to the first linear drive 32; a plurality of rollers 312 are arranged on the wheel frame 311 at equal intervals, the rollers 312 abut against the sides of the moving block 12, and track grooves for cooperating with the rollers 312 to move are provided on both sides of the moving block 12.

[0041] When the two swing mechanisms 3 drive the moving block 12 to swing through the abutment assembly 31, the interaction force between the abutment assembly 31 and the moving block 12 will cause the moving block 12 to encounter greater resistance when moving along the guide slide bar 11. Therefore, a wheel frame 311 and a plurality of rollers 312 are set. Some of the rollers 312 are kept in abutment with the track grooves on the moving block 12. The action force of the first linear drive 32 is applied to the moving block 12 through some of the rollers 312. When the moving block 12 moves along the guide slide bar 11, rolling friction occurs between the moving block 12 and the plurality of rollers 312. The rolling friction has less resistance to the moving block 12, thereby ensuring that the moving block 12 can move smoothly and efficiently along the guide slide bar 11.

[0042] Reference Figure 4 , Figure 7 and Figure 8As shown in the figure, the first reciprocating mechanism 1 also includes a first driving structure 14, which is arranged on the side of the frame plate away from the guide slide bar 11. The first driving structure 14 includes a first transmission plate 141, a first driving arm assembly 143 and an elastic telescopic arm 144; a second slide groove 1411 is provided on the first transmission plate 141, and a first transmission connecting rod 121 is provided on the side of the moving block 12 facing the first transmission plate 141. The first transmission connecting rod 121 is slidably arranged in the second slide groove 1411, and first guide columns 142 are slidably arranged at both ends of the first transmission plate 141. The guide column 142 is parallel to the guide slide bar 11; the first driving arm assembly 143 is arranged on one side of the first transmission plate 141, and one end of the first driving arm assembly 143 is axially connected to the middle part of the first transmission plate 141; the elastic telescopic arm 144 is arranged at one end of the first driving arm assembly 143, and one end of the elastic telescopic arm 144 is connected to the end of the first driving arm assembly 143; the first driving structure 14 also includes a first rotation driver 145, the first rotation driver 145 is arranged at the other end of the elastic telescopic arm 144, and the first rotation driver 145 is located in the middle of the two first guide columns 142.

[0043] When the lead tube 2 is located in the middle position of the outer winding stator, the first driving arm assembly 143 and the elastic telescopic arm 144 are colinear and parallel to the first transmission plate 141. At this time, the elastic telescopic arm 144 is in a stretched state, and its length is the same as that of the first driving arm assembly 143. When it is necessary to drive the moving block 12 to move along the guide slide bar 11, the first rotary driver 145 drives the elastic telescopic arm 144 to rotate, and the rotation of the elastic telescopic arm 144 drives the first driving arm assembly 143 to rotate. At this time, an angle is formed between the elastic telescopic arm 144 and the first transmission plate 141, and the force acting on the first driving plate 825 will decompose a component force parallel to the first guide column 142. The first driving plate 825 has a tendency to move. As the elastic telescopic arm 144 contracts, the end of the first driving arm assembly 143 connected to the elastic telescopic arm 144 approaches the first rotary driver 145, while the end connected to the first transmission plate 141 moves away. Through the cooperation of the second slide groove 1411 and the first transmission connecting rod 121, the lead tube 2 is driven to move toward one end of the outer winding stator. As the first rotary driver 145 continues to drive the elastic telescopic arm 144 to rotate, the elastic telescopic arm 144 continuously contracts and stretches, and the force direction of the first transmission plate 141 changes repeatedly, thereby realizing the equidistant movement of the lead tube 2 between the two ends of the outer winding stator, thereby improving the winding accuracy.

[0044] Reference Figure 7 and Figure 8As shown: the first driving arm assembly 143 includes two connecting sleeves 1431 and a first adjusting bolt 1432; the two connecting sleeves 1431 are respectively hinged to the first transmission plate 141 and the elastic telescopic arm 144, and threaded holes are provided at opposite ends of the two connecting sleeves 1431; the first adjusting bolt 1432 is arranged between the two connecting sleeves 1431, and both ends of the first adjusting bolt 1432 are threaded parts, and the two threaded parts are respectively threadedly connected in the threaded holes of the two connecting sleeves 1431.

[0045] When the distance between the two ends of the outer winding stator is large, the lead tube 2 needs a larger moving range to wind the copper wire on the stator. The cooperation between the first driving arm assembly 143 and the elastic telescopic arm 144 may not be able to meet the moving range requirements of the lead tube 2. At this time, adjustment is made by rotating the first adjusting bolt 1432. As the first adjusting bolt 1432 rotates, the two connecting sleeves 1431 move away from each other, increasing the overall length of the first driving arm assembly 143. When the first driving arm assembly 143 and the elastic telescopic arm 144 are colinear and parallel to the first transmission plate 141, the length of the elastic telescopic arm 144 in the stretched state will also increase accordingly. When the elastic telescopic arm 144 contracts, the distance between one end of the adjusted first driving arm assembly 143 and the first rotating driver 145 remains the same as before the adjustment. Since the overall length of the first driving arm assembly 143 has increased, the distance between its other end and the first rotating driver 145 also increases, so that the maximum distance between the first transmission plate 141 and the first rotating driver 145 is increased, thereby enabling the lead tube 2 to reciprocate in a larger range.

[0046] Reference Figure 4 and Fig. 9 As shown, a sliding sleeve 122 is arranged in the middle of the moving block 12 , a first sliding block 123 is arranged in the middle of the sliding sleeve 122 , and a first sliding groove 111 matched with the first sliding block 123 is opened on the guide slide rod 11 .

[0047] The moving block 12 needs to move along the guide slide bar 11. During this process, the moving block 12 has a tendency to rotate around the axis of the guide slide bar 11. If the moving block 12 rotates around the axis of the guide slide bar 11, the lead tube 2 on the moving block 12 will deviate from the working position, resulting in the lead tube 2 being unable to accurately enter the stator slot. In order to avoid this situation, the first slider 123 and the first slide groove 111 are used to limit the moving block 12. The first slider 123 can slide freely in the first slide groove 111, so that the moving block 12 can move along the guide slide bar 11. At the same time, since the first slider 123 is always inside the first slide groove 111, it can effectively prevent the moving block 12 from rotating around the axis of the guide slide bar 11. Therefore, when the moving block 12 drives the guide slide bar 11 to rotate around the central axis 4, the lead tube 2 on the moving block 12 can always remain in line with one of the diameters of the outer winding stator, thereby ensuring that the lead tube 2 can accurately enter the stator slot.

[0048] Reference Figure 1 and Fig.10 As shown: a placement groove is provided in the middle of the central axis 4, and a guide groove extending from the placement groove to the placement end of the central axis 4 is provided on the surface of the central axis 4. The placement mechanism also includes a position adjustment mechanism 9, which is arranged at the placement end of the central axis 4 and is installed on the central axis 4. The position adjustment mechanism 9 includes a second linear drive 91, a limit ring 92, a third transmission plate 93 and two transmission columns 94. The second linear drive 91 is arranged in the placement groove, the limit ring 92 is sleeved on the central axis 4, the middle part of the third transmission plate 93 is connected to the output end of the second linear drive 91, and the two transmission columns 94 are respectively arranged at the two ends of the third transmission plate 93, and the two ends of the transmission column 94 are respectively connected to the limit ring 92 and the third transmission plate 93.

[0049] When it is necessary to place outer winding stators of different thicknesses on the central axis 4, first, one end of the outer winding stator is abutted against the limit ring 92, and then the second linear drive 91 starts to work according to the actual thickness of the outer winding stator. The second linear drive 91 adjusts the position of the outer winding stator on the central axis 4 through the action of the third transmission plate 93 and the two transmission columns 94. After the outer winding stators of different thicknesses are adjusted, the projection positions of their middle surfaces on the central axis 4 can be kept consistent. When the first driving arm assembly 143 and the elastic telescopic arm 144 are colinear and parallel to the first transmission plate 141, the lead tube 2 can be accurately positioned in the middle position of the outer winding stator. Therefore, during the reciprocating movement of the lead tube 2, the distance between the lead tube 2 and the two ends of the outer winding stator can be kept consistent, thereby adapting to outer winding stators of different thicknesses and meeting the winding requirements of various specifications without replacing or adjusting the equipment.

[0050] Reference Figure 1 , Fig.11 and Fig.12 As shown: the placement mechanism also includes a second reciprocating mechanism 8, which is arranged in the U-shaped frame 5, and the second reciprocating mechanism 8 is used to drive the central axis 4 to reciprocate along its diameter direction perpendicular to the frame plate, and the second reciprocating mechanism 8 includes a moving structure 81 and a second driving structure 82; the moving structure 81 includes a rotating shaft 811, a second driving arm assembly 812, a second transmission connecting rod 813 and a second transmission plate 814, the rotating shaft 811 is connected to the U-shaped frame 5 through a bearing, and one end of the rotating shaft 811 extends to the U-shaped frame 5. The second driving structure 82 is arranged on the outside of the U-shaped frame 5, and the second driving structure 82 is connected to the middle of the rotating shaft 811. The second transmission connecting rod 813 is arranged at the other end of the second driving arm assembly 812. The second transmission plate 814 is arranged at the upper end of the rotating mechanism 7. The second transmission plate 814 is provided with a third sliding groove 8141 which cooperates with the second transmission connecting rod 813. The second transmission plate 814 is fixedly connected to the upper end of the mounting block 71. The second driving structure 82 is arranged on the outside of the U-shaped frame 5, and the second driving structure 82 is transmission-connected to one end of the rotating shaft 811.

[0051] When the first reciprocating mechanism 1 and the swing mechanism 3 work together to wind the copper wire around the outer winding stator, the second reciprocating mechanism 8 is also started synchronously, and the second driving structure 82 drives the rotating shaft 811 to rotate. Through the transmission of the second driving arm assembly 812, the second transmission connecting rod 813 moves smoothly in the third slide groove 8141. As the second transmission connecting rod 813 moves from one end of the third slide groove 8141 to the middle, the second transmission connecting rod 813 applies a gradually increasing pushing force to the second transmission plate 814. The force drives the mounting block 71 to move stably along the second guide column 72, so that the outer winding stator moves along the diameter direction colinear with the lead tube 2 until the distance between the two reaches the shortest, and then the second transmission connecting rod 813 continues to move from the middle of the third slide groove 8141 to the other end, and the outer winding stator gradually moves away from the lead tube 2. The movement process of the second transmission connecting rod 813 is reciprocated in the third slide groove 8141, thereby ensuring that the copper wire can be evenly and tightly wound on the outer winding stator in layers.

[0052] Reference Fig.12 and Fig.13As shown: the second driving arm assembly 812 includes a U-shaped plate 8121 and a second adjusting bolt 8123; the U-shaped plate 8121 is covered on the outside of the rotating shaft 811, and a connecting seat 8122 is provided at the open end of the U-shaped plate 8121, and the connecting seat 8122 is connected to the second transmission connecting rod 813; the second adjusting bolt 8123 is arranged at one end of the U-shaped plate 8121, and one end of the second adjusting bolt 8123 passes through the U-shaped plate 8121 and is threadedly connected to the rotating shaft 811, and a spring 8124 is sleeved on the second adjusting bolt 8123, and the two ends of the spring 8124 are respectively abutted against the end of the second adjusting bolt 8123 and the end of the U-shaped plate 8121.

[0053] When it is necessary to adjust the distance between the outer winding stator and the lead tube 2, rotate the second adjusting bolt 8123. As the second adjusting bolt 8123 rotates, it will move toward the rotating shaft 811 and drive the U-shaped plate 8121 to move accordingly through the transmission action of the spring 8124. Due to the movement of the U-shaped plate 8121, the connecting seat 8122 installed at one end thereof moves away from the rotating shaft 811, thereby driving the distance between the second transmission connecting rod 813 and the rotating shaft 811 to increase. When the second transmission connecting rod 813 is moved to the middle of the third slide groove 8141, the distance between the second transmission plate 814 and the rotating shaft 811 will be significantly increased compared to before adjustment, resulting in an increase in the moving distance of the central axis 4, thereby realizing the adjustment of the distance between the outer winding stator and the lead tube 2 to meet the winding requirements of copper coils with different numbers of layers.

[0054] Reference Fig.10 and Fig.14 As shown: the second driving structure 82 includes a gear 821, a third guide column 823, a driving plate 825 and a driving swing arm 826; the gear 821 is connected to one end of the rotating shaft 811, and a rack 822 is meshed on one side of the gear 821; the third guide column 823 is arranged on one side of the rack 822, and a second slider 824 is slidably arranged on the third guide column 823, and the rack 822 is arranged on the second slider 824; the driving plate 825 is arranged on one side of the second slider 824, and one end of the driving plate 825 is axially connected to the second slider 824; the driving swing arm 826 is arranged at the other end of the driving plate 825, and one end of the driving swing arm 826 is axially connected to the other end of the driving plate 825; the second driving structure 82 also includes a third rotation driver 827, and the output end of the third rotation driver 827 is connected to the other end of the driving plate 825 arm.

[0055] When it is necessary to drive the rotating shaft 811 to rotate, the third rotation driver 827 starts working, driving the driving swing arm 826 to rotate, and the transmission through the driving plate 825 is converted into the reciprocating movement of the second slider 824 along the third guide column 823. As the second slider 824 moves, the rack 822 also moves back and forth accordingly. When the rack 822 moves toward one side of the gear 821, the rack 822 engages with the gear 821 to drive the rotating shaft 811 to rotate toward one side. Conversely, when the rack 822 moves toward the other side of the gear 821, the rack 822 engages with the gear 821 again to drive the rotating shaft 811 to rotate toward the other side, thereby realizing continuous adjustment of the rotation direction of the rotating shaft 811.
