Description

Technical Field

[0001] This invention relates to the field of motor manufacturing equipment technology, specifically to an adjustable winding mold. Background Technology

[0002] In the production process of generators and motors, the stator coils of low-voltage motors are usually made using the loose winding method. The stator coil is an important part of the generator and motor production process, and its quality directly affects the quality of the winding process. The general method for making loose windings is to use a winding machine. Currently, the motor stator winding mold core has a single function and can only wind a stator coil of one size. When it is necessary to wind stator windings of other sizes, new tooling is required to wind the required size coil, which increases production costs.

[0003] Chinese utility model patent CN216414135U discloses an adjustable motor winding mold, including several winding mold core frames, several baffle frames, and connecting rods. A winding mold core frame is positioned between every two baffle frames. The connecting rods pass through each winding mold core frame and baffle frame, causing the baffle frames and winding mold core frames to abut against each other and form a row. Each winding mold core frame has a winding mold core adjusting block connected to both ends, forming a winding mold core. The length of the winding mold core is adjusted by adjusting the position of the winding mold core adjusting block. One end of each baffle frame is connected to a baffle adjusting block, forming a baffle. The length of the baffle is adjusted by adjusting the position of the baffle adjusting block. The beneficial effect of this utility model is that by setting the winding mold core adjusting block and adjusting its position to adjust the length of the winding mold core, and by setting the baffle adjusting block and adjusting its position to adjust the length of the baffle, it is possible to complete the winding of stator coils of multiple specifications on the same winding mold core.

[0004] During use, the wire needs to be wound onto the winding mold. After the winding is completed, the mold and the coil need to be separated. The process is quite cumbersome and cannot guarantee the integrity of the coil when it is separated. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an adjustable winding die, which has the advantages of rapid winding and simplified post-winding steps. It solves the problem that the process of separating the die from the coil after winding is relatively cumbersome in existing equipment.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an adjustable winding die, comprising a bottom die, slide rails fixedly connected to both sides of the bottom die by bolts, a top block placed on the slide rails, a top screw placed on the bottom die, a transfer die fitted around the top screw, one side of the top block abutting against the periphery of the transfer die, by changing the position of the top block on the slide rails, the two transfer dies are fixedly clamped to the periphery of the top screw, an upper pressure die is provided on the top screw, mounting holes are provided on the upper pressure die and the bottom die, the top screw and the transfer die can be fixedly clamped between the upper pressure die and the bottom die through the mounting holes, and a coil is wound around the periphery of the transfer die;

[0009] The bottom mold and the upper mold are fixed to the turntable and the top plate of the worktable respectively through their own mounting holes. The set screw and the intermediate mold are clamped and fixed between the upper mold and the bottom mold without affecting the winding of the coil. After the coil is wound, the upper mold and the bottom mold are disassembled, and the top block is moved away from the intermediate mold. This allows the set screw, the intermediate mold and the wound coil to be easily removed from the bottom mold, and the coil can be directly installed on the stator of the motor for use.

[0010] Preferably, a gap is left between the two intermediate molds. The upper mold has a vertical groove perpendicular to the intermediate mold inside. A slider is fixedly installed inside the vertical groove. One end of a return spring is fixedly connected to the bottom surface of the slider. The other end of the return spring is fixedly connected to a sliding rod. The sliding rod is slidably installed in a fixed block. The fixed block is also fixedly installed in the vertical groove. The bottom of a V-shaped plate is fixedly connected to the bottom of the fixed block. The two side plates of the V-shaped plate are respectively installed on both sides of the sliding rod. Pressure sensors are fixedly installed on the outer wall of the two side plates of the V-shaped plate near the intermediate mold.

[0011] The pressure sensor is used to detect the pressure between the side wall of the transfer mold and the side wall of the V-shaped plate in the gap. After the transfer mold is snapped onto both ends of the set screw, the pressure sensor can detect whether the transfer mold and the set screw are firmly attached when the top block pushes against the transfer mold. After the coil is wound, the pressure sensor can also detect the tightness of the coil winding after the top block and the upper pressure mold are removed. At the same time, the sliding rod and V-shaped plate in the gap can support the wound coil and prevent the edge of the transfer mold from causing wear to the coil.

[0012] Preferably, an extension mold is provided between the two intermediate molds. A slot is provided in the center of the extension mold, into which the V-shaped plate can be inserted. An installation groove is also provided in the upper mold. A bidirectional lead screw is rotatably provided inside the installation groove. Threaded sleeves are threaded onto both ends of the bidirectional lead screw. Connecting blocks are fixedly connected to both ends of the threaded sleeves. A movable groove is also provided in the upper mold. The connecting blocks are slidably disposed in the movable groove. A height-adjustable sliding rod and a V-shaped plate are also provided in the connecting block through a return spring. The extension mold and the intermediate mold are separated by the gap. A sliding groove is also provided on the upper mold. A slidable slider is provided inside the sliding groove. The slider and the slidable sliding rod are fixedly connected to both ends of the return spring.

[0013] It should be noted that after the extension mold is first snapped onto the outside of the set screw, and then the two sides of the set screw are snapped onto the intermediate mold, when the upper mold is installed onto the bottom mold, the fixed V-shaped plate and slide rod are pushed into the slot under the elastic force of the return spring to position and calibrate the extension mold. At this time, the repositionable V-shaped plate and slide rod retract into the inside of the upper mold under the spring contraction. Then, by rotating the bidirectional screw, the two threaded sleeves can be changed in opposite directions simultaneously. When the repositionable slide rod and V-shaped plate move to the gap position between the intermediate mold and the extension mold, under the elastic force of the spring, the movable slide rod and V-shaped plate can be inserted into the gap between the intermediate mold and the extension mold to support the coil and prevent the coil from being worn by the edges of the extension mold and the intermediate mold.

[0014] Preferably, a rotating shaft is fixedly connected to the edge of the transfer mold, and two rotating plates are rotatably connected to the rotating shaft. One of the rotating plates is fixedly connected to the side plate of the transfer mold, and a buckle is fixedly connected to the other rotating plate. One end of a limit spring is fixedly connected to the side of the rotating plate connected to the buckle. A hook is provided on the rotating plate connected to the side plate of the transfer mold, and a hook is also provided on the upper surface of the transfer mold. The other end of the limit spring can be fixedly hung on different hooks.

[0015] It should be noted that before winding the coil, the end of the limiting spring with the hook is hung on the hook on the upper surface of the transfer mold, and the buckle is opened to facilitate the fixing and winding of the coil on the transfer mold. After the coil is wound, the end of the limiting spring with the hook is hooked on the hook on the rotating plate, so that the buckle limits the wound coil and can strengthen the winding tightness of the coil to prevent the coil from loosening.

[0016] Preferably, a controller is provided on the upper mold or the top plate of the worktable, and the controller is electrically connected to the pressure sensor.

[0017] Preferably, the slide rail has a guide groove inside, a lead screw is installed in the guide groove, a guide block is threaded onto the lead screw, the bottom of the top block is fixedly connected to the guide block, and the position of the top block on the slide rail is controlled by rotating the lead screw, thereby fixing the intermediate transfer mold.

[0018] Preferably, a rocker arm is fixedly mounted on the end of the lead screw away from the guide block, and anti-slip protrusions are evenly distributed on the outer peripheral wall of the rocker arm. The upper surface of the slide rail is provided with scale lines, and a pointer is provided on the top block at the position corresponding to the scale lines.

[0019] Preferably, there are two buckle plates arranged diagonally on the transfer mold, and two other diagonally positioned horizontal side baffles are provided on the transfer mold to prevent the coil from falling off the transfer mold.

[0020] Preferably, the outer surface of the transfer mold is provided with an annular groove to increase friction and facilitate the winding of the first layer of the coil.

[0021] Preferably, the number of extension modules is N, where N≥0, and the number of transfer modules is (N+2).

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the present invention provides an adjustable winding die, which has the following advantages:

[0024] 1. This adjustable winding die forms a stable clamping mechanism through mounting holes between the bottom die and the upper die, ensuring accurate positioning of the transfer die and the set screw during winding and preventing coil misalignment. During disassembly, only the upper die and the bottom die need to be separated, and the set screw, transfer die, and coil can be quickly removed by moving the top block, eliminating the complex disassembly steps of traditional dies. At the same time, the coil can be directly installed on the motor stator, reducing secondary processing steps and significantly improving coil production and assembly efficiency, making it especially suitable for mass production scenarios.

[0025] 2. This adjustable winding die, through the gap setting between two intermediate dies, combined with the V-shaped plate, slide rod, and return spring assembly with pressure sensor inside the upper die, achieves dual detection of the intermediate die fit and coil tightness, thereby improving the coil winding quality. When the top block abuts against the intermediate die, the pressure sensor monitors the fit pressure between the intermediate die and the top screw in real time to ensure stable installation. After the coil is wound, the pressure data fed back by the sensor can accurately determine the coil tightness, avoiding excessive looseness or tightness that could affect motor performance. In addition, the support of the slide rod and V-shaped plate for the coil effectively prevents wear on the coil at the edge of the intermediate die, ensuring the integrity of the coil insulation layer and reducing the risk of short circuit in the motor.

[0026] 3. This adjustable winding die, through an extension die and a movable V-shaped plate assembly controlled by a bidirectional lead screw, enables adaptive winding of coils of different lengths, thereby expanding the applicability of the equipment and protecting the coils. The extension die can achieve precise positioning through a slot and the V-shaped plate. With a design where N≥0, the total length of the winding die can be flexibly adjusted to meet the needs of various coil specifications. The movable V-shaped plate assembly driven by the bidirectional lead screw can automatically insert into the gap between the extension die and the intermediate die, forming a multi-point support structure to avoid wear and tear between the coil and the die edge. This modular design not only improves the versatility of the equipment but also ensures consistent coil winding shape through uniform support, improving product consistency.

[0027] 4. This adjustable winding die, through the rotating shaft, rotating plate, buckle plate, and adjustable limiting spring on the edge of the transfer die, achieves convenient fixation in the initial stage of coil winding and tight fixation after winding, thus preventing the coil from loosening and improving winding stability. Before winding, the limiting spring is hung on the hook on the upper surface of the transfer die, and the buckle plate can be opened to quickly fix the starting end of the coil. After winding, the hook position is switched so that the buckle plate tightly fastens the coil and applies stable pressure through the limiting spring, which can not only strengthen the tightness of the coil, but also prevent the coil from loosening during handling or installation. The buckle plate set diagonally cooperates with the side baffle to further prevent the coil from falling off and ensure the integrity of the coil shape. It is especially suitable for the production of coils for precision motors. Attached Figure Description

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] Example 1:

[0050] This embodiment provides an adjustable winding die, which has the following technical features.

[0051] Please see Figure 1-15 An adjustable winding die includes a bottom die 100, with slide rails 150 fixedly connected to both sides of the bottom die 100 by bolts. A top block 130 is placed on the slide rails 150, and a top screw 140 is placed on the bottom die 100. A transfer die 110 is fitted around the top screw 140. One side of the top block 130 abuts against the outer periphery of the transfer die 110. By changing the position of the top block 130 on the slide rails 150, the two transfer dies 110 are fixedly clamped to the outer periphery of the top screw 140. An upper pressure die 120 is provided on the top screw 140. Mounting holes are provided on the upper pressure die 120 and the bottom die 100. The top screw 140 and the transfer die 110 can be fixedly clamped between the upper pressure die 120 and the bottom die 100 through the mounting holes. A coil 180 is wound around the outer periphery of the transfer die 110.

[0052] It should be noted that the bottom mold 100 and the upper mold 120 are fixed to the turntable and the top plate of the worktable respectively through their own mounting holes, thereby clamping and fixing the top screw 140 and the intermediate mold 110 between the upper mold 120 and the bottom mold 100 without affecting the winding of the coil 180. After the coil 180 is wound, the upper mold 120 is disassembled from the bottom mold 100, and the top block 130 is moved away from the intermediate mold 110. This allows the top screw 140, the intermediate mold 110 and the wound coil 180 to be easily removed from the bottom mold 100, and the coil 180 can be directly installed on the stator of the motor for use.

[0053] In an optional embodiment, a gap 111 is left between the two transfer molds 110. The upper pressure mold 120 has a vertical groove perpendicular to the transfer mold 110. A slider 280 is fixedly installed inside the vertical groove. One end of a return spring 290 is fixedly connected to the bottom surface of the slider 280. The other end of the return spring 290 is fixedly connected to a slide rod 230. The slide rod 230 is slidably installed in the fixing block 220. The fixing block 220 is also fixedly installed in the vertical groove. The bottom of the fixing block 220 is fixedly connected to the bottom of the V-shaped plate 240. The two side plates of the V-shaped plate 240 are respectively installed on both sides of the slide rod 230. Pressure sensors are fixedly installed on the outer wall of the two side plates of the V-shaped plate 240 near the transfer mold 110.

[0054] It should be noted that the pressure sensor is used to detect the pressure between the side wall of the intermediate mold 110 and the side wall of the V-shaped plate 240 in the gap 111. After the intermediate mold 110 is snapped onto both ends of the set screw 140, when the set block 130 pushes against the intermediate mold 110, the pressure sensor can detect whether the intermediate mold 110 and the set screw 140 are firmly attached. After the coil 180 is wound, the top block 130 is removed from the intermediate mold 110 and the upper pressure mold 120 is removed from the intermediate mold 110. The pressure sensor can also detect the tightness of the winding of the coil 180. At the same time, the slide bar 230 and the V-shaped plate 240 provided in the gap 111 can support the wound coil 180 and prevent the edge of the intermediate mold 110 from causing wear to the coil 180.

[0055] In an optional embodiment, an extension mold 190 is provided between the two intermediate molds 110. A slot 191 is provided at the center of the extension mold 190, into which a V-shaped plate 240 can be inserted. An mounting groove 121 is also provided in the upper mold 120. A bidirectional lead screw 210 is rotatably mounted inside the mounting groove 121. Threaded sleeves 250 are threaded onto both ends of the bidirectional lead screw 210, and connecting blocks 260 are fixedly connected to both ends of the threaded sleeves 250. The upper mold 120 also has... A movable groove 122 is provided, and a connecting block 260 is slidably disposed in the movable groove 122. The connecting block 260 is also provided with a height-adjustable slide rod 230 and a V-shaped plate 240 through a return spring 290. There is a gap 111 between the two sides of the extension mold 190 and the intermediate mold 110. A sliding groove 270 is also provided on the upper pressing mold 120. A sliding slider 280 is provided inside the sliding groove 270. The slider 280 and the slide rod 230 that can be slidably changed position are respectively fixedly connected to the two ends of the return spring 290.

[0056] It should be noted that after the extension mold 190 is first snapped onto the outside of the ejector screw 140, and then the two sides of the ejector screw 140 are snapped onto the intermediate mold 110, when the upper mold 120 is installed onto the bottom mold 100, the fixed V-shaped plate 240 and slide rod 230 are pushed into the slot 191 under the elastic force of the return spring 290 to position and calibrate the extension mold 190. At this time, the repositionable V-shaped plate 240 and slide rod 230 retract into the upper mold 120 under the spring contraction, and then the bidirectional screw is rotated. Rod 210 can simultaneously change the position of the two threaded sleeves 250 in opposite directions. When the movable slide rod 230 and V-shaped plate 240 move to the gap 111 between the intermediate mold 110 and the extension mold 190, under the elastic force of the spring, the movable slide rod 230 and V-shaped plate 240 can be inserted into the gap 111 between the intermediate mold 110 and the extension mold 190 to support the coil 180 and prevent the coil 180 from being worn by the edges of the extension mold 190 and the intermediate mold 110.

[0057] In an optional embodiment, a rotating shaft 113 is fixedly connected to the edge of the transfer mold 110. Two rotating plates 114 are rotatably connected to the rotating shaft 113. One rotating plate 114 is fixedly connected to the side plate of the transfer mold 110, and a buckle plate 112 is fixedly connected to the other rotating plate 114. One end of a limit spring 115 is fixedly connected to the side of the rotating plate 114 connected to the buckle plate 112. A hook is provided on the rotating plate 114 connected to the side plate of the transfer mold 110. A hook is also provided on the upper surface of the transfer mold 110. The other end of the limit spring 115 can be fixedly hung on different hooks.

[0058] It should be noted that before winding the coil 180, the end of the limiting spring 115 with the hook is hung on the hook on the upper surface of the transfer mold 110, and the buckle plate 112 is opened, so as to facilitate the fixing and winding of the coil 180 onto the transfer mold 110. After the coil 180 is wound, the end of the limiting spring 115 with the hook is hooked on the hook on the rotating plate 114, so that the buckle plate 112 limits the wound coil 180 and can strengthen the winding tightness of the coil 180, preventing the coil 180 from loosening.

[0059] In an optional embodiment, a controller is provided on the upper mold 120 or the top plate of the worktable, and the controller is electrically connected to the pressure sensor.

[0060] In an optional embodiment, a guide groove 151 is provided inside the slide rail 150, and a lead screw 170 is provided in the guide groove 151. A guide block 160 is threaded onto the lead screw 170, and the bottom of the top block 130 is fixedly connected to the guide block 160. The position of the top block 130 on the slide rail 150 is controlled by rotating the lead screw 170, thereby fixing the intermediate transfer mold 110.

[0061] In an optional embodiment, a rocker arm 171 is fixedly mounted on the end of the lead screw 170 away from the guide block 160. Anti-slip protrusions are evenly distributed on the outer peripheral wall of the rocker arm 171. A scale line is provided on the upper surface of the slide rail 150, and a pointer is provided on the top block 130 at the position corresponding to the scale line.

[0062] In an optional embodiment, two buckle plates 112 are provided and are diagonally arranged on the transfer mold 110. The transfer mold 110 is provided with two other diagonally arranged horizontal side baffles to prevent the coil 180 from falling off the transfer mold 110.

[0063] In an optional embodiment, the outer surface of the transfer mold 110 is provided with an annular groove to increase friction and facilitate the winding of the first layer of the coil 180.

[0064] In an optional embodiment, the number of extension modules 190 is N, where N≥0, and the number of transfer modules 110 is N+2.

[0065] Working principle: The device is fixed to the turntable and the top plate of the worktable respectively through the mounting holes of the bottom mold 100 and the upper pressure mold 120. The position is adjusted by the top block 130 on the slide rail 150, so that the two intermediate transfer molds 110 are fixedly engaged with the outer periphery of the set screw 140. At the same time, the upper pressure mold 120 and the bottom mold 100 clamp and fix the set screw 140 and the intermediate transfer molds 110 through the mounting holes, ensuring that the mold is stable and does not affect the winding operation when the coil 180 is wound; during the winding process, the spacing between the intermediate transfer molds 110 is... Within gap 111, the V-shaped plate 240V of the upper pressure mold 120, under the action of the return spring 290, is inserted into gap 111 to support the edge of the coil 180 and prevent wear. The pressure sensor can detect the fit of the intermediate mold 110 and the tightness of the coil 180. If the specifications of the coil 180 need to be adjusted, an extension mold 190 can be added. The movable V-shaped plate 240V is driven by the bidirectional lead screw 210170 to insert into the gap 111 between the extension mold 190 and the intermediate mold 110. The fixed V-shaped plate 240V and slide bar 230 can be inserted into the slot 191 of the extension mold 190 under the elastic force of the return spring 290 to perform the core setting process of the extension mold 190. This allows the extension mold 190 to be positioned in the center of the winding mold, which facilitates the winding of the coil 180 and realizes multi-segment mold combination support. The buckle plate 112 of the transfer mold 110 cooperates with the limit spring 115. It is opened before winding to facilitate the fixing of the coil 180, and closed after winding to reinforce the coil 180 and prevent it from loosening. After winding, the upper pressure mold 120 and the bottom mold 100 can be removed. The top block 130 can be moved to remove the top screw 140, the transfer mold 110 and the coil 180. The coil 180 can be directly installed on the motor stator. The position of the top block 130 can be adjusted by the lead screw 170 to realize the quick fixing and disassembly of the mold. With the help of the scale line and controller, the operation accuracy and efficiency can be improved. The annular groove and the side baffle further ensure the stability of the winding of the coil 180.

[0066] In summary, this adjustable winding die, through the bottom die 100 and the upper pressure die 120 forming a stable clamping structure via mounting holes, ensures the precise positioning of the transfer die 110 and the set screw 140 during winding, preventing the coil 180 from shifting. During disassembly, only the upper pressure die 120 and the bottom die 100, and the moving top block 130 need to be separated to quickly remove the set screw 140, the transfer die 110, and the coil 180, eliminating the complex disassembly steps of traditional dies. At the same time, the coil 180 can be directly installed on the motor stator, reducing secondary processing steps and significantly improving the production and assembly efficiency of the coil 180, making it particularly suitable for mass production scenarios.

[0067] This adjustable winding die, through the gap 111 between two intermediate dies 110, combined with the V-shaped plate 240V with pressure sensor inside the upper pressure die 120, slide rod 230 and return spring 290 assembly, achieves dual detection of the fit of the intermediate die 110 and the tightness of the coil 180, thereby improving the winding quality of the coil 180. When the top block 130 abuts against the intermediate die 110, the pressure sensor monitors the contact pressure between the intermediate die 110 and the top screw 140 in real time to ensure stable installation. After the coil 180 is wound, the pressure data fed back by the sensor can accurately determine the tightness of the coil 180, avoiding excessive looseness or tightness that may affect motor performance. In addition, the supporting effect of the slide rod 230 and V-shaped plate 240V on the coil 180 effectively prevents the edge of the intermediate die 110 from wearing down the coil 180, ensuring the integrity of the insulation layer of the coil 180 and reducing the risk of short circuit in the motor.

[0068] This adjustable winding die, through an extension die 190 and a movable V-shaped plate 240V assembly controlled by a bidirectional lead screw 210170, enables adaptive winding of coils 180 of different lengths, thereby expanding the applicability of the equipment and protecting the coils 180. The extension die 190 can achieve precise positioning by engaging with the V-shaped plate 240V through a slot 191. With a design where N≥0, the total length of the winding die can be flexibly adjusted to meet the needs of various specifications of coils 180. The movable V-shaped plate 240V assembly driven by the bidirectional lead screw 210170 can automatically insert into the gap 111 between the extension die 190 and the intermediate die 110, forming a multi-point support structure to prevent the coils 180 from contacting and wearing against the edge of the die. This modular design not only improves the versatility of the equipment but also ensures consistent winding shape of the coils 180 through uniform support, thus improving product consistency.

[0069] This adjustable winding die, through the rotating shaft 113, rotating plate 114, buckle plate 112, and adjustable limiting spring 115 on the edge of the transfer die 110, achieves convenient fixation of the coil 180 in the initial winding stage and tight fixation after winding, thereby preventing the coil 180 from loosening and improving winding stability. Before winding, the limiting spring 115 is hung on the hook on the upper surface of the transfer die 110, and the buckle plate 112 can be opened to quickly fix the starting end of the coil 180. After winding, the hook position is switched so that the buckle plate 112 tightly fastens the coil 180 and applies stable pressure through the limiting spring 115, which can not only strengthen the tightness of the coil 180, but also prevent the coil 180 from loosening during handling or installation. The buckle plate 112 set diagonally cooperates with the side baffle to further prevent the coil 180 from falling off and ensure the integrity of the coil 180 shape. It is especially suitable for the production of coils 180 for precision motors.
