[0001] This utility model relates to the field of winding machine technology, and in particular to a winding machine for motor coils. Background Technology

[0002] In modern industrial production, the demand for electric motors continues to grow and is showing a diversified trend, ranging from industrial automation equipment and drive motors for new energy vehicles to micro motors in smart homes. Different application scenarios have significantly different requirements for the specifications and performance of motors. As a key component of the motor, the quality of the winding process of the motor coil directly determines the motor's electrical performance, operational stability, and energy consumption level.

[0003] In existing technologies, some winding machines have fixed mounting frame structures, making it difficult to flexibly adjust them to accommodate coil conductors of different sizes. This results in poor equipment versatility and makes disassembly difficult, reducing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that it is difficult to replace different coil conductors during use, and to propose a winding machine for motor coils.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a winding machine for motor coils, comprising an operating table, a mounting frame, and a coil guide bar. The mounting frame is fixedly installed on the upper surface of the operating table, and the coil guide bar is fixedly connected to the upper surface of the mounting frame. A first motor is provided at the bottom of the mounting frame, and a reducer is fixedly connected to the output end of the first motor. The output end of the reducer is fixedly connected to the bottom of the mounting frame. A support frame is fixedly connected to the upper surface of the operating table, and a winding device is provided at the top of the support frame. A push plate is fixedly connected to the upper surface of the operating table.

[0006] The mounting bracket includes a fixed base, and a connecting plate is snapped onto the upper surface of the fixed base via a snap-fit ​​assembly. The bottom of the coil conductor is fixedly connected to the top of the connecting plate.

[0007] Furthermore, the upper surface of the fixed chassis is provided with a connecting groove, and the inner wall of the connecting groove is provided with a sliding groove.

[0008] Furthermore, the upper surface of the connecting plate is provided with a movable groove, and one end of the movable groove is provided with a recess.

[0009] Furthermore, the snap-fit ​​assembly includes a movable block that is fixedly and slidably connected to the inner wall of the slide groove. One side surface of the movable block is fixedly connected to a telescopic spring. The end of the telescopic spring away from the movable block is fixedly connected to the inner wall of the connecting groove. A limit block is fixedly connected to the top of the movable block.

[0010] Furthermore, the push plate includes an electric push rod fixedly connected to the upper surface of the operating table, and a push block is fixedly connected to the telescopic end of the electric push rod.

[0011] Furthermore, the winding device includes a servo motor and a winding machine body. A telescopic structure is fixedly connected to the top of the support frame, and a top plate is fixedly connected to the top of the telescopic structure. The servo motor is fixedly connected to the top of the top plate, and the output end of the servo motor is fixedly connected to the top of the winding machine body.

Simply pull the limiting block, and the moving block overcomes the elasticity of the telescopic spring, sliding within the groove. The limiting block disengages from the groove, allowing the connecting plate to be separated from the fixed base. To replace the connecting plate with the appropriate coil guide, the limiting block is passed through the groove, and the return of the telescopic spring engages the limiting block on the side of the movable groove away from the groove, thus fixing the connecting plate and the fixed plate together. This design greatly simplifies the coil guide replacement process, improves the equipment's adaptability to coil guides of different sizes, enhances the equipment's versatility, and increases production efficiency.

Detailed Implementation

[0017] Please see Figure 1-5 This utility model provides a technical solution: a winding machine for motor coils, including an operating table 1, a mounting frame 2 and a coil guide bar 3.

[0018] Mounting bracket 2 is fixedly mounted on the upper surface of operating table 1. Coil guide strip 3 is fixedly connected to the upper surface of mounting bracket 2. A first motor 4 is provided at the bottom of mounting bracket 2. A reducer 5 is fixedly connected to the output end of the first motor 4. The output end of the reducer 5 is fixedly connected to the bottom of mounting bracket 2. A support frame 6 is fixedly connected to the upper surface of operating table 1. A wire-inserting device 7 is provided at the top of support frame 6. A push plate 8 is fixedly connected to the upper surface of operating table 1.

[0019] The specific setup and function of mounting bracket 2 will be explained below.

[0020] In this embodiment: the mounting bracket 2 includes a fixed base 21, and a connecting plate 23 is snapped onto the upper surface of the fixed base 21 by a snap-fit ​​assembly 22. The bottom of the coil guide bar 3 is fixedly connected to the top of the connecting plate 23.

[0021] The effect achieved by the above components is that the fixed base 21 and the connecting plate 23 are connected by the snap-fit ​​assembly 22, which makes it easy to disassemble and install the connecting plate 23 and the coil guide 3 fixed thereon, making it possible to replace the coil guide 3 of different specifications, and improving the adaptability of the winding machine to the production of different motor coils.

[0022] Specifically, the upper surface of the fixed chassis 21 is provided with a connecting groove 211, and the inner wall of the connecting groove 211 is provided with a sliding groove 212.

[0023] The effects achieved by the above components are as follows: the connecting groove 211 provides installation space for the connecting plate 23, so that it can be stably embedded into the fixed chassis 21; the sliding groove 212 provides a sliding track for the moving block 221 in the snap-fit ​​assembly 22, ensuring that the moving block 221 can move stably within the fixed chassis 21.

[0024] Specifically, the upper surface of the connecting plate 23 is provided with a movable groove 231, and one end of the movable groove 231 is provided with a recess 232.

[0025] The effect achieved by the above components is as follows: the movable groove 231 provides the movable space for the limiting block 223 in the snap-fit ​​assembly 22, so that it can move on the connecting plate 23; the groove 232 is used to cooperate with the limiting block 223. When the limiting block 223 is snapped into the groove 232, the connecting plate 23 can be firmly fixed on the fixed base plate 21 to prevent the connecting plate 23 from shifting during the wire embedding process.

[0026] Specifically, the snap-fit ​​assembly 22 includes a movable block 221 that is fixedly slidably connected to the inner wall of the slide groove 212. One side surface of the movable block 221 is fixedly connected to a telescopic spring 222. One end of the telescopic spring 222 away from the movable block 221 is fixedly connected to the inner wall of the connecting groove 211. A limit block 223 is fixedly connected to the top of the movable block 221.

[0027] The effect achieved by the above components is as follows: the telescopic spring 222 provides elastic force to the moving block 221, and pushes the moving block 221 under normal conditions, so that the limiting block 223 is inserted into the movable groove 231, thereby fixing the connecting plate 23 to the fixed base plate 21; when it is necessary to disassemble the connecting plate 23, the limiting block 223 is pulled to drive the moving block 221 to overcome the spring force and slide in the slide groove 212, so that the limiting block 223 is disengaged from the groove 232, thereby making it easy to remove the connecting plate 23.

[0028] Specifically, the push plate 8 includes an electric push rod 81 fixedly connected to the upper surface of the operating table 1, and a push block 82 is fixedly connected to the telescopic end of the electric push rod 81.

[0029] The effect achieved by the above components is that the electric push rod 81 can precisely control the extension and retraction of the push block 82. During the winding process, the electric push rod 81 drives the push block 82 to accurately push the motor coil to the predetermined winding position, thereby improving the efficiency and accuracy of winding.

[0030] Specifically, the winding device 7 includes a servo motor 71 and a winding machine body 72. The top of the support frame 6 is fixedly connected to a telescopic structure 73, and the top of the telescopic structure 73 is fixedly connected to a top plate 74. The servo motor 71 is fixedly connected to the top of the top plate 74, and the output end of the servo motor 71 is fixedly connected to the top of the winding machine body 72. The winding machine body 72 and the top plate 74 are connected in a through connection.

[0031] The effects achieved by the above components are as follows: the servo motor 71 can precisely control the operation of the winding machine body 72, realizing the precise winding operation of the motor coil; the telescopic structure 73 and the top plate 74 provide an adjustable mounting platform for the servo motor 71 and the winding machine body 72, and the height of the winding machine body 72 can be adjusted according to different winding requirements to adapt to the winding work of motor coils of different specifications.

[0032] Specifically, the telescopic structure 73 includes an electric telescopic rod 731 fixedly connected to the top of the support frame 6. The telescopic end of the electric telescopic rod 731 is fixedly connected to the bottom of the top plate 74. A buffer spring 732 is provided on the outer surface of the electric telescopic rod 731.

[0033] The effects achieved by the above components are as follows: the electric telescopic rod 731 can realize the electric adjustment of the height of the top plate 74, which is convenient and highly accurate; the buffer spring 732 can effectively absorb and buffer the vibration generated by the winding machine body 72 when it is working, reduce the impact of equipment vibration on winding accuracy, and extend the service life of the equipment.

[0034] Specifically, a support column 11 is fixedly connected to the bottom of the operating table 1, and a base 12 is fixedly connected to the bottom of the support column 11.

[0035] The effect achieved by the above components is that the support column 11 and the base 12 together provide a stable support structure for the winding machine, ensuring that the winding machine remains stable during operation and enhancing the overall stability of the equipment.

[0036] Working principle: Before the motor coil winding operation, according to the specifications of the motor coil to be processed, pull the limiting block 223 to drive the moving block 221 to slide in the slide groove 212 against the elastic force of the telescopic spring 222, so that the limiting block 223 is disengaged from the groove 232. Remove the original connecting plate 23 and the fixed base plate 21, replace the connecting plate 23 with the matching coil guide strip 3, pass the limiting block 223 through the groove 232, and under the action of the telescopic spring 222, the limiting block 223 is re-clamped into the movable groove 231, completing the replacement of the coil guide strip 3. Next, the height of the top plate 74 is adjusted by the electric telescopic rod 731, which drives the servo motor 71 and the winding machine body 72 to move up and down, adjusting the winding machine body 72 to a suitable working height, and the buffer spring 732 absorbs the vibration during the adjustment process. The first motor 4 is started, and after being reduced in speed and torque by the reducer 5, it drives the mounting bracket 2 to rotate, allowing the working angle of the coil guide 3 to be adjusted at any time. Then, the motor coil is placed on the operating table 1, and the electric push rod 81 is started to drive the push block 82, accurately pushing the motor coil to the bottom of the coil guide 3. Finally, the servo motor 71 is started to drive the winding machine body 72 to operate. The winding machine body 72 accurately embeds the motor coil into the coil guide bar 3. During the winding process, the buffer spring 732 continuously buffers the vibration generated by the winding machine body 72 to ensure the stability and accuracy of the winding, and completes the winding work of the motor coil.
