Description

Technical Field

[0002] The stator winding of a motor is a key component in the motor. The stator winding refers to a series of conductive coils installed on the stator. The main function of the stator winding is to generate a rotating magnetic field, which interacts with the magnetic field of the rotor to drive the rotor to rotate or generate an electromotive force.

[0003] The outer dimension of the motor stator winding is a relatively important dimension in the motor winding. If the inner circle of the winding wire package is too small, it may cause the rotor to be unable to penetrate or the rotor to scratch the wire package, resulting in a burnt package. If the outer diameter of the winding wire package is too large, the winding cannot be inserted into the shell or the winding collides with the machine shell, resulting in grounding and a burnt package. If the height of the winding wire package is too large, the end cover cannot be buckled or the winding collides with the end cover, resulting in grounding and a burnt package.

[0004] For the above reasons, during the manufacturing process of the winding, the control of the outer dimensions of the wire package is quite strict, but the detection of the outer dimensions of the winding wire package is relatively difficult, time-consuming and laborious.

[0028] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, rather than to limit the scope of the present utility model.

[0029] A detecting tool for a small motor winding wire package in this embodiment relates to the technical field of motor assembly. A rotatable tooling is provided, and an area for detecting the size of the winding wire package is formed on the tooling. The detection of the winding wire package is simple, reliable, and has high accuracy.

[0030] Please refer to Figures 1 to 5 , a detecting tool for a small motor winding wire package in this embodiment includes: a positioning assembly 100, a central axis assembly 200, and a detecting assembly 300. The positioning assembly 100 includes a base 110. The base 110 is coaxially arranged with the stator core, so that the base 110 is located at the center of the stator core. The bottom of the base 110 can be clamped in the stator core, which can make the height of the base 110 relatively fixed.

[0031] The central axis assembly 200 includes a central axis 210. The axis of the central axis 210 coincides with the axis of the base 110. The central axis 210 is perpendicular to the base 110, which can provide effective support for the detecting assembly 300, ensure that the reference axis of the entire detecting device is consistent with the axis of the stator, and provide an accurate reference for subsequent detection. The bottom of the central axis 210 is detachably connected to the base 110, and the central axis 210 can be disassembled and assembled as needed.

[0032] The detection component 300 includes a detection piece 310. The detection piece 310 includes a support plate 311 and a limiting plate 312. The support plate 311 is arranged perpendicular to the central axis 210. The two limiting plates 312 are connected to the support plate 311 and are perpendicularly arranged relative to the base 110. The two limiting plates 312 and the support plate 311 form a detection area that is closed on three sides and open on one side. The relatively enclosed three sides of the detection area can perform dimensional verification and detection on the inner circle, outer circle, and height of a part of the winding wire package to ensure that the dimensions of the winding wire package meet the requirements of the set dimensions. The support plate 311 is rotatably connected to the central axis 210. The rotating detection piece 310 can comprehensively detect the annular winding wire package, simplify the process of the outer dimensions of the winding wire package, and improve the detection accuracy.

[0033] It should be noted that: a stepped portion is provided at the bottom end of the base 110. The stepped portion can be adapted to the inner cavity of the stator core. One section of the stepped portion is inserted into the inner cavity of the stator core, and the other section of the stepped portion abuts against the end of the stator core to achieve the positioning and limiting of the base 110 in the height direction, ensure the controllability of the height of the support plate 311, and thus verify the height of the wire package.

[0034] In some embodiments, the limiting plate 312 is detachably connected to the support plate 311, and the distance between the two limiting plates 312 can be adjusted. By adjusting the distance between the limiting plates 312, winding wire packages of different sizes can be adapted, so that the detection device has a larger applicable range. In the specific implementation process, the sizes of the motor winding wire packages of different models may be different. The function of adjusting the distance between the limiting plates 312 enables the same detection tooling to be used to detect wire packages of different sizes, eliminating the need to manufacture special detection devices for wire packages of each size, saving time and cost. At the same time, by precisely adjusting the distance between the limiting plates 312, the accuracy and consistency during the detection process can be ensured, and the detection accuracy can be improved.

[0035] As one of the implementation manners, the two limiting plates 312 are symmetrically arranged about the center of the central axis 210. The distance between the limiting plate 312 and the central axis of the central axis 210 is close to the outer radius of the wire package. Through the rotational movement of the detection piece 310, the two limiting plates 312 can inspect the outer dimensions of the wire package.

[0036] As one of the implementation manners, the two limiting plates 312 are symmetrically arranged about the center of the central axis 210. The distance between the limiting plate 312 and the central axis of the central axis 210 is close to the inner radius of the wire package. Through the rotational movement of the detection piece 310, the two limiting plates 312 can inspect the inner dimensions of the wire package.

[0037] As one of the implementation manners, the two limiting plates 312 are arranged on one side of the central axis 210. The distance between one limiting plate 312 and the central axis of the central axis 210 is close to the inner radius of the wire coil, and the distance between one plate 312 and the central axis of the central axis 210 is close to the outer radius of the wire coil. The two limiting plates 312 can cooperate with each other to simultaneously inspect and verify the inner and outer dimensions of the wire coil.

[0038] In a further implementation manner, a chute is provided on the support plate 311. The limiting plate 312 is clamped in the chute and is slidably connected to the support plate 311. The slider can move freely along the support plate 311. A locking bolt is arranged on the limiting plate 312. After the limiting plate 312 moves to a preset position, the locking bolt is tightened to fix the limiting plate 312.

[0039] As an alternative implementation manner, the limiting plate 312 is connected to the support plate 311 through a bolt hole with a long slot. The bolt passes through the long slot, allowing the limiting plate 312 to slide within a certain range. A long slot is provided on the support plate 311, and a corresponding bolt hole is provided on the limiting plate 312. After the bolt is loosened, the limiting plate 312 can slide in the long slot and is fixed by tightening the bolt after being adjusted to the required position.

[0040] It should be noted that when the limiting member 310 is used as a single inspection tool, the limiting plate 312 and the support plate 311 can be integrally connected to form a whole, so that the distance between the two limiting plates 312 remains constant.

[0041] In some embodiments, the bottom of the limiting plate 312 relatively close to the central axis 210 is slidably connected to the base 110. The limiting plate 312 can provide support for the support plate 311 with a long span, improving the connection stability of the support plate 311. In addition, by controlling the height of the limiting plate 312, the length of the support plate 311 along the axial direction of the central axis 210 can be verified, avoiding the inclination of the support plate 311 and interfering with the verification of the height of the winding wire coil.

[0042] In some embodiments, the support plate 311 is provided with length scales. The length scales are marked on the support plate 311, which can help the operator accurately know the current position and distance when adjusting the position of the limiting plate 312. The intuitive visual reference helps to avoid errors caused by visual inspection and estimation, improving the accuracy and consistency of the adjustment. When it is necessary to detect winding wire coils of the same specification multiple times, the operator can quickly reset the limiting plate 312 to the previously used position according to the scale, ensuring the same detection conditions each time. This improvement in repeatability can effectively ensure the consistency and reliability of the detection results and reduce errors caused by different adjustment positions.

[0043] In some embodiments, please refer to Figure 3 and Figure 4, the detection component 300 further includes a connection unit 320. The connection unit 320 includes a sleeve 321. The sleeve 321 is sleeved on the central shaft 210. The sleeve 321 is rotatably connected to the central shaft 210 through a bearing. The outer ring of the bearing is embedded in the sleeve 321, and the inner ring of the bearing is sleeved on the central shaft 210. The sleeve 321 can rotate freely relative to the central shaft 210. As a connecting member between the sleeve 321 and the central shaft 210, the bearing can ensure the stable rotation of the sleeve 321 relative to the central shaft 210, ensuring the stability of the support plate 311 and the accuracy of detection. The bearing can also reduce the friction between the sleeve 321 and the central shaft 210, avoid detection errors caused by friction, and improve the reliability and accuracy of detection.

[0044] In some embodiments, please refer to Figure 3 , the connection unit 320 further includes a U-shaped joint 322 and a screwing member 323. The U-shaped joint 322 is fixedly connected to the sleeve 321 and is arranged with the opening facing upward. The support plate 311 is inserted into the U-shaped joint 322. The U-shaped joint 322 is connected to the support plate 311 through the screwing member 323. The support plate 311 can be directly inserted into the U-shaped joint 322 and fixed through the screwing member 323 (such as bolts, knobs, etc.) to complete the installation. The corresponding design simplifies the installation process of the support plate 311. The operator can disassemble and assemble without using complex tools, improving the operation efficiency. Especially in the case where the support plate 311 needs to be frequently replaced or the position needs to be adjusted, the operation time can be significantly reduced.

[0045] An installation groove is formed inside the U-shaped joint 322. The installation groove provides a stable support and fixation for the support plate 311. The screwing member 323 ensures that the support plate 311 does not loosen during use, improving the overall stability and avoiding errors and failures caused by loosening during the detection process.

[0046] In some embodiments, please refer to Figure 1 and Figure 3 , a handle 211 is provided at the top of the central shaft 210. The handle 211 is specifically a bent shape. The operator can hold and lift the entire detection tooling through the bent handle 211, facilitating the movement and handling of the detection tooling.

[0047] In some embodiments, please refer to Figure 3 , the bottom of the central shaft 210 is detachably connected to the base 110. In the specific implementation process, threads are provided at the bottom of the central shaft 210, and a through hole is provided in the middle of the base 110. The central shaft 210 is inserted into the through hole, and a nut is screwed onto the bottom of the central shaft 210 to complete the fixation and connection of the central shaft 210 and the base 110.

[0048] Workflow: First, place the winding wire package to be detected on the detection workbench. Then, according to the design and manufacturing standards of the corresponding wire package, determine the dimensions of the inner and outer circles and the height direction of the wire package, adjust the distance between the two limit plates 312, insert the step portion of the base 110 into the stator core, and realize the positioning of the wire package in the height direction, so that the base 110 is arranged relative to the center of the winding wire package, and the wire package winding is located in the area formed by the support plate 311 and the two limit plates 312. Finally, rotate the detection piece 310 to determine whether the size of the annular wire package winding meets the standard.

[0049] As mentioned above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the present invention.
