Detailed Implementation

[0030] The technical solution of the present invention will be described below with reference to the accompanying drawings. However, it should be noted that the following is only for illustration and does not limit the scope of this application.

[0031] The winding head of this application is used in a winding machine for winding wire onto the iron core of an electric motor. Figure 1 The image shows a disc-type motor core. The winding machine of this application can be used to wind the wire of a chain motor core. After winding, the chain motor core is then coiled into a ring-like shape, such as a square or a circle.

[0032] Reference Figures 2-7 , Figures 2-7 This illustrates various structures for winding the wire. For the sake of simplicity, this article uses... Figure 5 A detailed diagram illustrating the winding of the wire end is provided. Among them, Figure 6 yes Figure 5 The diagram shows a cross-sectional view of the wound end. Figure 7 yes Figure 5 The diagram shown is a three-dimensional exploded view of the wound end. Figures 2-4 The internal structure of the winding head shown can be roughly referred to Figure 6 The component assembly structure can be roughly referenced.Figure 7 .

[0033] Reference Figure 2 and combined Figure 6 and Figure 7 As shown, the winding head 61 includes a shaft 601, a guide pin assembly 603, a guide wheel 604, a rotating fitting 60, and a locking member 606. The shaft 601 has a radially stepped portion 6014 and a main body portion 6015. The guide pin assembly 603 is mounted below the radially stepped portion 6014, and is located away from the main body portion 6015 relative to the radially stepped portion 6014. The rotating fitting 60 is sleeved on the main body portion 6015. The rotating fitting 60 has an upper end portion 60a and a lower end portion 60b along the axial direction of the shaft. The lower end portion 60b of the rotating fitting 60 abuts against the radially stepped portion 6014, and the upper end portion 60a of the rotating fitting 60 abuts against the locking member 606. Thus, the rotating fitting is pressed tightly in the axial direction of the shaft by the radially stepped portion and the locking member, and can transmit torque when the rotating fitting is subjected to external force, facilitating the rotation of the shaft.

[0034] The locking element 606 can be a fixing nut or other snap ring structure. In this document, the term "mutual restraint" includes both direct contact restraint and restraint achieved by setting an intermediate component.

[0035] The rotating mating component includes at least a bearing 602, a synchronous pulley 605, and a washer. The bearing 602, synchronous pulley 605, and washer are fitted onto the main body 6015. When the synchronous pulley rotates, it drives the shaft to rotate; that is, the bearing 602, synchronous pulley 605, and washer abut against each other in the axial direction. The number of bearings, synchronous pulleys, and washers is not limited; there can be one or more bearings 602, one or more synchronous pulleys, and one or more washers. The axial arrangement order of the bearings, synchronous pulleys, and washers is not limited. In this text, "the bearing 602, synchronous pulley 605, and washer abutting against each other in the axial direction" includes situations where adjacent bearings and pulleys are in an abutting state even when they have different axial arrangement orders.

[0036] Bearing 602 can be a needle roller bearing, a ball bearing, or a combination of needle roller and ball bearing. Synchronous pulley 605 has grooves on its surface for accommodating a timing belt, such as a belt. The timing pulley is used for torque transmission between the timing belt and the shaft.

[0037] Reference Figure 7The rotating mating component 60 has at least a first washer 6052 and a second washer 6053, which are located on opposite axial sides of the bearing 602. The bearing 602 has an inner wall portion 6021 and an outer wall portion 6022, and has a first end portion 6023 and a second end portion 6024 in the axial direction. The second end portion 6024 of the inner wall portion 6022 abuts against the first washer 6052, and the first end portion 6023 of the inner wall portion abuts against the second washer 6053. This abutment of the first and second ends of the inner wall portion of the bearing ensures that the components of the rotating mating component have a large static friction force in the axial direction, while avoiding the influence of the outer wall portion of the bearing.

[0038] The shaft 601 has a communicating cavity 6012 inside and a side groove 6013. The communicating cavity 6012 extends axially and communicates with the side groove 6013. Along the axial direction of the shaft, the side groove 6013 is located below the radial step portion 6014.

[0039] The guide wheel 604 is at least partially located in the side groove 6013, and a portion of the peripheral wall 6041 of the guide wheel 604 is located within the axially extending region of the connecting cavity 6012. The guide needle assembly 603 is mounted below the shaft 601. A portion of the peripheral wall of the guide wheel includes a guide wheel groove, so that the thread, after passing through the connecting cavity, is guided by the guide wheel and enters the guide needle, ensuring smooth thread routing.

[0040] The winding head of the above technical solution has a shaft 601, with a communicating cavity 6012 inside the shaft 601. The shaft 601 has a side groove 6013. The communicating cavity 6012 extends axially and communicates with the side groove 6013. The guide wheel 604 is at least partially located in the side groove 6013, and at least a portion of the peripheral wall of the guide wheel 604 is located within the axially extending region of the communicating cavity 6012. The guide needle assembly 603 is installed below the shaft 601. Therefore, the wire used for winding the head can be located in the communicating cavity 6012, and the wire can enter the side groove 6013 from the communicating cavity 6012 via the guide wheel 604 and pass through the guide needle assembly 603. In this embodiment, when the winding head rotates at high speed, because the wire passes through the inside of the communicating cavity 6012 of the winding head, the wire path is clean and neat, with less interference to the winding process, making winding easier. At the same time, the spindle also protects the cable, making it less likely to get tangled in other spindles when the cable breaks, resulting in a clean cable routing and easier maintenance.

[0041] The guide needle assembly 603 includes a guide needle 6032 and a guide needle mounting seat 6031. The guide needle mounting seat 6031 is sleeved on the shaft 601. The guide needle mounting seat 6031 is located below the bearing 602 and the guide needle mounting seat 6031 and the shaft 601 are assembled and fixed. The guide needle 6032 is axially inserted into the guide needle mounting seat 6031. The guide needle 6032 is located below the side groove 6013 and protrudes radially relative to the guide wheel 604.

[0042] The guide pin 6032 protrudes from the guide wheel 604 in the radial direction. Thus, the size of the winding coil can be adjusted by changing the radial distance of the guide pin 6032.

[0043] The lower part of the shaft 601 has a protruding section 6011. The guide pin mounting seat 6031 is sleeved on the protruding section 6011. The guide pin mounting seat 6031 has a fixing part 6033, a guide pin mounting part 6035, and a fixing member 6037. The guide pin mounting part 6035 protrudes radially relative to the guide wheel 604 and has an axial through hole 6036. At least a portion of the guide pin 6032 is located in the axial through hole 6036. The fixing part 6033 has a radial through hole 6034. At least a portion of the fixing member 6037 is located in the radial through hole 6034. The fixing member 6037 is used for assembling the guide pin mounting seat 6031 and the protruding section 6011. The fixing member is, for example, a lock nut. By adjusting the fixing member 6037, the fixing angle of the fixing part 6033 in the circumferential direction of the protruding section 6011 can be adjusted. Alternatively, by controlling the locking force of the 6037 fastener, the guide pin mounting seat can be finely adjusted with a larger external force without loosening the fastener, making the operation simple.

[0044] The guide pin mounting base 6031 and the shaft 601 are fixed by assembly. If a radial clamping structure is adopted, after the position of the shaft 601 is determined, the angle of the guide pin 6032 in the circumferential direction can be adjusted in a timely manner by the slight movement of the guide pin mounting base 6031. In this way, the direction of the guide pin 6032 can be adjusted more precisely by fine-tuning the guide pin mounting base 6031, so that the direction of the guide pin 6032 can be independent of the shaft 601, resulting in higher accuracy and stronger adaptability of subsequent winding.

[0045] The winding head has a ceramic eye 6061, which is installed on the top of the shaft. The ceramic eye 6061 has a through hole 6062 inside. The inner wall of the ceramic eye is smooth and is used to guide the wire into the connecting cavity 6012 inside the shaft. The diameter of the through hole 6062 of the ceramic eye 6061 is smaller than the diameter of the connecting cavity 6012, so that when the wire is inserted into the shaft, the guide of the ceramic eye reduces the risk of the wire being scratched due to contact with the inner wall of the shaft.

[0046] The rotating fitting is located above the side cavity 6013, so the transmission connection of the winding head has less interference with the wire routing in the side cavity 6013, making winding more convenient.

[0047] The rotating mating part 60 has various structures, as shown below. Figures 2-5 Provide a detailed description.

[0048] As one implementation method, refer to Figure 2 The rotating mating component 60 has two synchronous pulleys, two bearings, and three washers. The winding head can have more than two synchronous pulleys. These pulleys can be used for transmission connection with the drive component; they can also be used for transmission connection with different winding heads to improve winding efficiency.

[0049] In this embodiment, the synchronous pulley of the winding head 61 includes a driving pulley 611 and a first driven pulley 612, and the washers include a first washer 6052, a second washer 6053, and a third washer 6054. The driving pulley 611 is sleeved on the main body and abuts against the radial step portion 6014. The first washer 6052 is located between the driving pulley 611 and one of the bearings 602. The second washer 6053 is located between the two bearings 602. The third washer 6054 is located above the other bearing 602 and between it and the first driven pulley 612. The top of the first driven pulley 612 abuts against the top locking member 606.

[0050] In this embodiment, the driving pulley 611 can be used to drive the drive unit, for example, via belt drive. The first driven pulley 612 can be used to drive the winding head, for example, via belt drive. In this way, the winding head 61 and the winding head driven by the winding head 61 via the first driven pulley 612 can be controlled simultaneously by a single drive unit, resulting in high winding efficiency.

[0051] As one implementation method, refer to Figure 3 The rotating mating part 60 has two synchronous pulleys, two bearings, and three washers. In this embodiment, the synchronous pulleys of the winding head 62 include a second driven pulley 621 and a fifth driven pulley 622, and the washers include a first washer 6052, a second washer 6053, and a third washer 6054. The first washer 6052 is fitted onto the main body and abuts against the radial stepped portion 6014. The lower end of one of the bearings 602 abuts against the first washer 6052. The second washer 6053 is located between the two bearings 602, and the top of the other bearing 602 abuts against the third washer 6054. The second driven pulley 621 is located between the fifth driven pulley 622 and the third washer 6054, and the top of the fifth driven pulley 622 abuts against the top locking member 606.

[0052] As one implementation method, refer to Figure 4The rotating mating part 60 has a synchronous pulley, two bearings, and four washers. In this embodiment, the synchronous pulley of the winding head 63 includes a fourth driven pulley 631, and the washers include a first washer 6052, a second washer 6053, a third washer 6054, and a fourth washer 6055. The first washer 6052 is fitted onto the main body and abuts against the radial stepped portion 6014. The lower end of one of the bearings 602 abuts against the first washer 6052. The second washer 6053 is located between the two bearings 602, and the top of the other bearing 602 abuts against the third washer 6054. The fourth driven pulley 631 is located between the third washer 6054 and the fourth washer 6055, and the top of the fourth washer 6055 abuts against the top locking member 606.

[0053] As one implementation method, refer to Figure 5 The rotating mating part 60 has three synchronous pulleys, two bearings, and three washers. In this embodiment, the synchronous pulleys of the winding head 61' include a driving pulley 611, a first driven pulley 612, and a third driven pulley 613, and the washers include a first washer 6052, a second washer 6053, and a third washer 6054. The driving pulley 611 is fitted onto the main body and abuts against the radial stepped portion 6014. The first washer 6052 is located between one of the bearings 602 and the driving pulley 611. The second washer 6053 is located between two bearings 602, and abuts against the third washer 6054 above the other bearing 602. The third driven pulley 613 is fitted onto the first driven pulley 612, and the first driven pulley 612 is located above the third washer 6054. The top of the third driven pulley 613 abuts against the top locking member 606. In this embodiment, the driving wheel 611 can be connected to the driving member for transmission, the first driven wheel 612 can be connected to another winding head for transmission, and the third driven wheel 613 can be connected to a third winding head for transmission. In this way, a single driving member can simultaneously drive the common rotation of three winding heads, resulting in high winding efficiency.

[0054] The above are merely illustrative examples. Since the composition of the rotating parts can change depending on the actual situation, they will not be listed individually here. It should be understood that, in other embodiments, the winding head may have only one synchronous pulley, which is driven to rotate synchronously by a drive component or other winding heads. The winding head may also have more synchronous pulleys than in the embodiments described above. The above embodiments all include two bearings to ensure a more secure and stable structure when the winding head is fixed via the outer wall of the bearing. In other embodiments, there may be one or more bearings.

[0055] Reference Figure 3 and Figure 5 The synchronous pulley can be located on the same side of the bearing 602 or on different sides of the bearing 602.

[0056] ReferenceFigure 8 , Figure 8 The structure of the winding component is illustrated. The winding component includes two or more winding heads, defined as a first winding head 61 and a second winding head 62. The first winding head 61 and the second winding head 62 are arranged side-by-side in the height direction of the shaft 601. The synchronous pulley of the first winding head 61 includes at least a driving pulley 611 and a first driven pulley 612, and the synchronous pulley of the second winding head 62 includes at least a second driven pulley 621. The first driven pulley 612 and the second driven pulley 621 are positioned correspondingly in the height direction of the shaft 601. The driving pulley 611 can be used for transmission connection with a driving element, such as belt drive. The first driven pulley 612 and the second driven pulley 621 can also be transmission connected, for example, via belt drive. Thus, the rotation of the first winding head 61 and the second winding head 62 can be controlled simultaneously by a single driving element, resulting in high winding efficiency.

[0057] Along the axial direction of the shaft 601, the driving pulley 611 and the first driven pulley 612 are respectively disposed on both sides of the bearing 602. Distributing the driving pulley 611 and the first driven pulley 612, which are used for transmission connection with the drive component, on both sides of the bearing 602 facilitates the connection of belt drive and makes the structure more compact.

[0058] The winding component 9 has a bushing 609 and a winding head. The bushing 609 is sleeved on the winding head, and also sleeved on the first winding head 61 and the second winding head 62. The bushing 609 and the outer wall of the bearing 602 of the first winding head 61 are fixed or limited, and the bushing 609 and the outer wall of the bearing 602 of the second winding head 62 are also fixed or limited. The first winding head 61 and the second winding head 62 can rotate relative to the bushing 609. Fixing the first winding head 61 and the second winding head 62 to the same bushing facilitates structural layout and installation control.

[0059] More specifically, Figure 8 The winding component 9 shown has a first winding head 61, a second winding head 62, and a third winding head 63, which are arranged in a row.

[0060] Specifically, the winding component 91 includes a first winding head 61, a second winding head 62, and a third winding head 63. The first winding head 61, the second winding head 62, and the third winding head 63 are arranged side by side in the height direction of the shaft 601. The synchronous pulley of the first winding head 61 includes at least a driving pulley 611, a first driven pulley 612, and a third driven pulley 613. The synchronous pulley of the second winding head 62 includes at least a second driven pulley 621. The synchronous pulley of the third winding head 63 includes at least a fourth driven pulley 631. The first driven pulley 612 and the second driven pulley 621 are positioned opposite each other in the axial direction of the shaft 601, and the third driven pulley 613 and the fourth driven pulley 631 are positioned opposite each other in the height direction of the shaft 601.

[0061] The driving wheel 611 can be used to drive the drive shaft of the driving member, the first driven wheel 612 and the second driven wheel 621 are driven together, and the third driven wheel 613 and the fourth driven wheel 631 are driven together. In this way, the first winding head 61, the second winding head 62 and the third winding head 63 can be rotated simultaneously by a single driving member.

[0062] As described above, the winding component has a first winding head 61, a second winding head 62, and a third winding head 63, which are arranged in a row. The bearings 602 of the first winding head 61, the second winding head 62, and the third winding head 63 are arranged in the same row, and these three bearings 602 are fixed to a first bushing 6091. Thus, by fixing the first winding head 61, the second winding head 62, and the third winding head 63 to the bushing 609, each winding head can rotate relative to the first bushing 6091. Furthermore, fixing the first winding head 61, the second winding head 62, and the third winding head 63 to a certain extent reduces the assembly inconsistency caused by fixing the first winding head 61, the second winding head 62, and the third winding head 63 with different fixing structures, thereby improving operational stability. The first winding head 61, the second winding head 62, and the third winding head 63 can be used to simultaneously wind the workpiece on the three motor pole shoes of a workpiece at one station of the winding machine, resulting in high winding efficiency.

The structures of the first winding component 91, the second winding component 92, and the third winding component 93 can refer to the winding component 9 described above, but are slightly different.

[0068] The first winding head 61, the fifth winding head 65, and the eighth winding head 68 can be used to simultaneously wind the three motor pole shoes of a workpiece at one station of the winding machine. The second winding head 62, the fourth winding head 64, and the ninth winding head 69 can also be used to simultaneously wind the three motor pole shoes of a workpiece at one station of the winding machine. The third winding head 63, the sixth winding head 66, and the seventh winding head 67 can also be used to simultaneously wind the three motor pole shoes of a workpiece at one station of the winding machine. Thus, this embodiment can provide winding for three stations of the winding machine at once, and can provide winding for three pole shoes for each station, resulting in high winding efficiency.

[0069] The driving component 73 includes a first sub-driving component 731, a second sub-driving component 732, and a third sub-driving component 733. The first sub-driving component 731 is connected to the first winding head 61, the first winding head 61 is connected to the second winding head 62, and the second winding head 62 is connected to the third winding head 63.

[0070] The second sub-drive component 732 is driven to the fourth winding head 64, the fourth winding head 64 is driven to the fifth winding head 65, and the fourth winding head 64 is driven to the sixth winding head 66.

[0071] The third sub-drive component 733 is driven to the seventh winding head 67, the seventh winding head 67 is driven to the eighth winding head 68, and the eighth winding head 68 is driven to the ninth winding head 69.

[0072] In this embodiment, three sub-drive components drive nine winding heads, which not only effectively utilizes the efficiency of the drive components, but also ensures the consistency of the operation of the same sub-drive component.

[0073] The first winding head 61, the second winding head 62, and the third winding head 63, driven or driven by the first sub-drive component 731, are defined as the first winding group; the fourth winding head 64, the fifth winding head 65, and the sixth winding head 66, driven or driven by the second sub-drive component 732, are defined as the second winding group; and the seventh winding head 67, the eighth winding head 68, and the ninth winding head 69, driven or driven by the third sub-drive component 733, are defined as the third winding group.

[0074] In the first winding assembly, along the height direction of the shaft 601, the first winding head 61 has a first driving wheel 611 located below the bearing 602 and a first driven wheel 612 located above the bearing 602. The first driving wheel 611 is synchronously driven and connected to the first sub-drive component 731.

[0075] The second winding head 62 has a second driven wheel 621 and a fifth driven wheel 622 located above the bearing 602. The second driven wheel 621 is in the same position as the first driven wheel 612 in the height direction of the shaft 601. The first driven wheel 612 and the second driven wheel 621 are synchronously connected for transmission.

[0076] The third winding head 63 has a fourth driven wheel 631 located above the bearing 602. The fourth driven wheel 631 is aligned with the fifth driven wheel 622 in the height direction of the shaft 601, and the fourth driven wheel 631 and the fifth driven wheel 622 are synchronously connected.

[0077] The winding head assemblies in the second and third winding groups are similar to those in the first winding group, and will not be described in detail below. The fourth winding head 64 has a second driving pulley 611, and the seventh winding head 67 has a third driving pulley 611. The second and third driving pulleys 611 are located below the bearing 602. The remaining driven pulleys are all located above the bearing 602 of their respective winding heads. Thus, in terms of structural layout, the driving component can drive or rotate the winding head below the bearing 602, and the transmission belt connecting the synchronous pulley is arranged above the bearing 602, making the structure appear more compact.

[0078] The winding assembly 6 has a fixing frame 607, a bushing 609, and a winding component. The bushing 609 is sleeved on the winding component and fixed to the fixing frame 607. The bushing may also include a mounting bracket 901 for fixing to the fixing frame.

[0079] In this embodiment, there are three bushings 609, referred to as the first bushing 6091, the second bushing 6092, and the third bushing 6093. There are also three winding components, referred to as the first winding component, the second winding component, and the third winding component. The first bushing 6091, the second bushing 6092, and the third bushing 6093 are all fixed to the fixing frame 607. A portion of the first winding component is located on the first bushing 6091, and the first winding component can rotate relative to the first bushing 6091. A portion of the second winding component is located on the second bushing 6092, and the second winding component can rotate relative to the second bushing 6092. A portion of the third winding component is located on the third bushing 6093, and the third winding component can rotate relative to the third bushing 6093. The bearings 602 of the first winding head 61, the second winding head 62, and the third winding head 63 are arranged in the same row. These three bearings 602 are fixed to the first bushing 6091. Thus, by fixing the first winding head 61, the second winding head 62, and the third winding head 63 to the first bushing 6091, each winding head can rotate relative to the first bushing 6091. Furthermore, fixing the first winding head 61, the second winding head 62, and the third winding head 63 to a certain extent reduces the assembly inconsistency that would result from fixing them with different fixing structures, thereby improving operational stability. The cooperation method between the second bushing 6092 and the second winding component, and the cooperation method between the third bushing 6093 and the third winding component, is the same as the cooperation method between the first bushing 6091 and the first winding component, and will not be described again here.

[0080] The drive unit 73 is fixed to the fixing bracket 607 and arranged in a row on the fixing bracket 607, so that the space occupied by the drive unit in the height direction of the fixing bracket 607 is small, and the size of the winding assembly 6 in the height direction is small.

[0081] More specifically, the mounting bracket 607 has a bottom wall portion 608 and a side wall portion 6071. The bottom wall portion 608 has a first fixing hole 6081 and a second fixing hole 6082. At least a portion of the drive shaft of the drive member is located in the first fixing hole 6081, and a portion of the winding member is located in the second fixing hole 6082. The end of the drive shaft of the drive member 73 and the drive wheel 611 of the winding member are located on the same side of the bottom wall portion 608.

[0082] In another embodiment, the winding component includes a fixing frame 607, a bushing 609 sleeved on the first winding head 61 and the second winding head 62, the bushing 609 and the outer wall of the bearing 602 of the first winding head 61 being fixed or limited, the bushing 609 and the outer wall of the bearing 602 of the second winding head 62 being fixed or limited, the first winding head 61 and the second winding head 62 being rotatable relative to the bushing 609, and the bushing 609 being fixed to the fixing frame 607. Fixing the first winding head 61 and the second winding head 62 to the same fixing frame facilitates structural layout and installation control.

[0083] The fixing frame 607 has a bottom wall portion 608 and a side wall portion 6071. The bottom wall portion 608 has a first fixing hole 6081 and a second fixing hole 6082. At least a portion of the drive shaft of the drive member is located in the first fixing hole 6081, and a portion of the winding component is located in the second fixing hole 6082. The end of the drive shaft of the drive member 73 and the drive wheel 611 are located on the same side of the bottom wall portion 608. The drive member, the first winding head 61, and the second winding head 62 are fixed to the fixing frame 607, and the overall structure of the winding assembly 6 is compact by arranging the structure of the drive member, the first winding head 61, and the second winding head 62.

[0084] The aforementioned winding assembly 6 can be used in a winding machine, see reference. Figure 14 , Figure 14 The diagram illustrates a winding machine including the aforementioned winding assembly 6. When used for winding, the machine controls three winding heads arranged in the same row via a first sub-drive component. These three sub-drive components can simultaneously control the rotation of nine winding heads, resulting in high winding efficiency. Furthermore, the winding heads utilize the aforementioned structure, leading to higher winding head precision and greater machine stability.
