Description

Technical Field

[0001] This application relates to the field of enameled wire winding technology, and in particular to an enameled wire winding machine for motor production. Background Technology

[0002] As a key material for motor windings, the insulation performance and mechanical integrity of enameled wire directly affect the electrical characteristics and service life of the motor. During the motor production process, the enameled wire needs to be evenly wound onto the winding rollers by winding equipment to form a regular coil structure.

[0003] Existing winding equipment typically consists of a drive motor, winding rollers, and guide wheels, which directionally convey the enameled wire by pulling the guide wheels.

[0004] However, a certain tension needs to be applied to the enameled wire during the winding process to ensure the winding tightness. When the speed of the drive motor fluctuates or the winding resistance changes abruptly, the traction force is likely to exceed the tolerance threshold of the enameled wire sheath, causing a sudden increase in pressure on the contact surface with the metal guide wheel, which may lead to cracking of the insulating varnish layer or even exposure of the copper wire.

[0005] Such damage not only reduces the insulation performance of the coil, but also exacerbates the spread of defects during the subsequent impregnation process, causing a risk of short circuit in the motor;

[0006] In other words, existing technologies have the following technical problems: ordinary winding mechanisms are prone to damaging the surface of the enameled wire during winding. Therefore, an enameled wire winding machine for motor production is proposed to address the above problems. Summary of the Invention

[0038] Please see Figure 1-4 As shown, an enameled wire winding machine for motor production includes:

[0039] The winding assembly 1 includes a fixed base plate 101, a frame 102, a winding roller 103, and a drive motor 104;

[0040] The enameled wire guide assembly 2 is fixedly installed on the upper surface of the fixed base plate 101, and is used to guide the enameled wire 4.

[0041] The enameled wire guide assembly 2 is provided with a fracturing protection structure, which supports and protects the enameled wire 4.

[0042] Tension control component 3 is fixedly installed on the upper surface of fixed base plate 101. Tension control component 3 is connected to enameled wire guide component 2. Tension control component 3 is used to control the tension of enameled wire 4.

[0043] Through the above technical solution, the fracturing protection structure combined with the tension control component 3 can effectively protect the enameled wire 4 on the guide wheel, and at the same time control the tension force, avoiding the phenomenon of cracking of the outer sheath of the enameled wire 4 due to excessive tension force. It is particularly suitable for winding processing of enameled wire.

[0044] The frame 102 is fixedly mounted on the upper surface of the fixed base plate 101. A winding roller 103 is rotatably connected to the frame 102. A drive motor 104 is fixedly connected to one side of the frame 102. The output shaft end of the drive motor 104 is fixedly connected to the winding roller 103. Through this technical solution, the operation of the drive motor 104 can drive the winding roller 103 to rotate, thereby realizing the winding operation of the enameled wire 4.

[0045] The enameled wire guide assembly 2 includes a fixed support 201, a guide wheel 202, and a connecting support 203. There are two fixed supports 201, and the upper ends of the two fixed supports 201 are rotatably connected to the guide wheel 202. The upper end of the connecting support 203 is rotatably connected to the guide wheel 202.

[0046] The fracturing protection structure includes an annular rubber air cushion 204, a small hole 205, a rotary joint 206, and a connecting hose 207. The annular rubber air cushion 204 is fixedly installed on the arc-shaped wall of the guide wheel 202. Through this technical solution, the annular rubber air cushion 204 provides support and protection for the enameled wire 4 being guided, thus protecting it from excessive tension and preventing cracking of the enameled wire sheath caused by excessive contact pressure.

[0047] The guide wheel 202 has an inner cavity, and the inner cavity wall of the guide wheel 202 has several small holes 205, which extend into the inner cavity of the annular rubber air cushion 204.

[0048] The rotary joint 206 is disposed on the side wall of the fixed support 201. One end of the rotary joint 206 extends into the inner cavity of the guide wheel 202, and the other end of the rotary joint 206 is rotatably connected to the connecting hose 207.

[0049] The tension control assembly 3 includes an electric cylinder 301, a connecting circular plate A302, a control spring 303, a connecting circular plate B304, a fixed cylinder 305, a moving piston 306, and a moving guide rod 307. The electric cylinder 301 is fixedly mounted on the upper surface of the fixed base plate 101. The connecting circular plate A302 is fixedly connected to the upper end of the electric cylinder 301. One end of the control spring 303 is fixedly connected to the upper surface of the connecting circular plate A302, and the other end of the control spring 303 is fixedly connected to the connecting circular plate B304. The connecting circular plate B304 is fixedly connected to the bottom surface of the connecting support 203. With this technical solution, when tensioning the enameled wire 4, the tension can be adjusted by extending and retracting the electric cylinder 301, thereby causing the control spring 303 to contract. By adjusting the contraction stroke of the control spring 303, the tensioning force can be adjusted, avoiding the problem of cracking damage caused by excessive tensioning pressure on the enameled wire 4.

[0050] A fixed cylinder 305 is fixedly connected to the upper surface of the connecting circular plate A302, and a movable piston 306 is slidably connected in the inner cavity of the fixed cylinder 305.

[0051] One end of a movable guide rod 307 is fixedly connected to the upper surface of the movable piston 306. The other end of the movable guide rod 307 penetrates the upper wall of the inner cavity of the fixed cylinder 305 and extends to the outside of the wall. The upper end of the movable guide rod 307 is fixedly connected to the bottom surface of the connecting circular plate B304.

[0052] One end of the connecting hose 207 extends into the inner cavity of the fixed cylinder 305 and is connected to the fixed cylinder 305. Through this technical solution, when the control spring 303 contracts, the moving guide rod 307 moves downward, thereby driving the moving piston 306 to move downward in the inner cavity of the fixed cylinder 305. This allows the gas in the inner cavity of the fixed cylinder 305 to be transported to the inner cavity of the guide wheel 202 through the connecting hose 207, and then enters the inner cavity of the annular rubber air cushion 204 through the small hole 205, causing the annular rubber air cushion 204 to expand, providing further support and protection for the enameled wire 4, and avoiding the phenomenon of skin cracking caused by excessive pressure during traction.

[0053] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
