Description

Technical Field

[0001] This application relates to the field of motor rotor processing and testing technology, and in particular to an automatic rotor runout detection device. Background Technology

[0002] Currently, in the field of motor manufacturing, the coaxiality detection of rotating components such as rotors is a key step in ensuring the quality of motor products. With the improvement of industrial automation, traditional manual inspection methods can no longer meet the requirements of modern motor manufacturing for inspection efficiency and accuracy.

[0003] In the existing technology, the coaxiality of motor rotors is detected manually using a dial indicator, which involves manually rotating the rotor and observing the needle's movement, or using semi-automatic equipment where the rotor is driven by a motor and the reading is taken manually. Although the coaxiality of the rotor is detected by these two methods, the manual readings have large errors, are inaccurate, and are prone to mistakes.

[0004] Regarding the aforementioned technologies, since the coaxial testing of the rotor is performed manually, the manual readings are prone to errors and inaccuracies, leading to inaccurate testing and impacting production efficiency. Summary of the Invention

[0005] To address the issues of large errors, inaccurate values, and susceptibility to mistakes in manual readings, which lead to inaccurate detection and reduced production efficiency, this application provides an automatic rotor runout detection device.

[0006] This application provides an automatic rotor runout detection device, which adopts the following technical solution: The rotor automatic runout detection device includes a worktable, a reference base for placing the rotor is provided directly above the worktable, a rotation power mechanism is provided on the worktable and the rotation power mechanism is located on one side of the reference base, and a detection mechanism for rotor runout detection is provided on the other side of the reference base. The rotary power mechanism includes a base and a pair of slide rails. The bottom of the base is fixed to the workbench. The pair of slide rails are arranged on both sides of the base. A slide plate is slidably connected to the slide rails. The base is provided with a forward and backward cylinder that pushes the slide plate to move. The output end of the forward and backward cylinder is connected to a push plate. The end of the push plate away from the forward and backward cylinder is connected to the slide plate. The top of the push plate and both ends of the top of the slide plate are rotatably connected to pulleys. A belt is provided on the pulleys. A drive component is provided at the bottom of the slide plate. The drive component is connected to the pulleys on the slide plate. The testing mechanism includes a lever testing head and a Keyence testing head. The lever testing head is disposed on the surface of the reference base, and the Keyence testing head is disposed on the worktable. The Keyence testing head is used in conjunction with the lever testing head through a lever. A touch screen for numerical display is disposed on the worktable, and the touch screen is electrically connected to the Keyence testing head.

[0007] By adopting the above technical solution, the rotor on the reference base is driven to rotate by the belt on the rotating power mechanism. When the rotor rotates, it contacts the lever detection head on the detection mechanism. The lever detection head amplifies the runout of the rotor through the lever principle. Combined with the Keyence detection head, the Keyence detection head detects the runout amplified by the lever detection head and transmits the runout value to the touch screen for real-time display. This detects the coaxiality of the rotor without the need for manual operation of rotation or detection, reducing human intervention and greatly improving detection efficiency. The equipment can automatically detect runout, replacing manual reading and identification. It can complete the detection in one go, thereby shortening the detection time and improving production efficiency.

[0008] Preferably, the reference base includes a support sleeve, a bearing, and a reference steel sleeve. The bottom of the support sleeve is connected to the worktable, the outer surface of the bearing is connected to the inner wall of the support sleeve, and the surface of the reference steel sleeve is connected to the inner surface of the bearing.

[0009] By adopting the above technical solution, the reference steel sleeve is used as the component that directly contacts the rotor. Its surface precision is high, which can provide a precise support reference for the rotor. The support sleeve, through its fixed connection with the worktable, provides a stable mounting base for the entire reference seat, reducing shaking or displacement during the testing process. The bearing setting allows the reference steel sleeve to rotate flexibly relative to the support sleeve. When the rotor is driven to rotate by the rotating power mechanism, the reference steel sleeve can rotate synchronously with the rotor, avoiding sliding friction between the rotor and the reference seat. This reduces wear on the rotor surface, lowers rotational resistance, and ensures the smoothness of rotor rotation.

[0010] Preferably, the lever detection head is embedded in the surface of the reference seat on the side closest to the reference seat, and the side of the lever detection head closest to the inner side of the rotor is in contact with the inner surface of the rotor.

[0011] By adopting the above technical solution, the lever detection head is embedded in the surface of the reference base, which can form a stable relative positional relationship with the reference base, avoiding errors caused by the positional deviation of the detection head itself during the detection process; at the same time, the lever detection head directly contacts the inner surface of the rotor, which can directly collect the runout data of the inner circle of the rotor, reducing the transmission error caused by indirect detection and improving the accuracy of the detection data.

[0012] Preferably, the bottom of the Keyence detection head is provided with a support base for supporting the Keyence detection head, and the bottom of the support base is fixedly connected to the top of the workbench.

[0013] By adopting the above technical solution and setting up a support base, the Keyence detection head is provided with a stable installation foundation, which prevents the Keyence detection head from shifting its position due to its own weight or equipment vibration. This ensures that the cooperation between the Keyence detection head and the lever detection head is always accurate, reduces measurement errors caused by the shaking of the Keyence detection head, and guarantees the stability and reliability of the detection data.

[0014] Preferably, a triangle is formed between the pulleys on the push plate and the slide plate, and the belt also forms a stable triangle on the pulleys.

[0015] By adopting the above technical solution, and by forming a triangular layout between the pulley and the belt, the belt can always maintain a suitable tension, reduce power loss caused by belt slack, ensure that the power of the drive components is efficiently transmitted to the rotor, and at the same time, the three-point contact can distribute the force on the belt, reduce the wear resistance at a single point, extend the service life of the belt, and reduce equipment downtime caused by belt slippage or breakage.

[0016] Preferably, the slide includes a pair of sliders and a support plate, the bottom of the support plate is fixedly connected to the sliders, the sliders are slidably connected to the slide rail, and the pulley and drive component are both mounted on the support plate.

[0017] By adopting the above technical solution, a pair of sliders cooperate with the slide rails on both sides to form symmetrical two-point support, which can effectively limit the lateral tilting or swaying of the support plate during the sliding process, ensure that the slide plate moves in a straight line along the slide rail direction, avoid changes in the contact position between the pulley and the rotor due to sliding deviation, ensure the stability of rotational power transmission, and provide a precise motion benchmark for jump detection.

[0018] Preferably, the workbench is equipped with an emergency stop button, which is used to control the emergency stop of the forward and reverse cylinders and the drive components.

[0019] By adopting the above technical solution, the emergency stop button provides operators with a direct means to quickly interrupt the operation of the equipment. When sudden situations such as rotor jamming, component collision, or belt abnormality occur during the testing process, the operator can immediately press the emergency stop button to stop the extension and retraction of the cylinder and the operation of the drive components, thereby avoiding continuous abnormal operation of the equipment that could lead to workpiece damage, mechanical wear, or even personal injury, and minimizing the probability of safety accidents.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a design of a reference base + rotating power mechanism + detection mechanism + touch screen, the motor rotor is placed on the reference base, the rotating power mechanism drives the motor rotor to rotate, the detection mechanism detects the motor rotor, and the touch screen displays and analyzes the data. This allows the equipment to automatically detect the rotational fluctuation value, replacing manual reading and identification. It can complete the detection in one go, thereby shortening the detection time and improving production efficiency. 2. By forming a triangular layout between the pulley and the belt, the belt can always maintain a suitable tension, reducing power loss caused by belt slack, ensuring efficient power transmission from the drive components to the rotor, and extending the belt's service life. 3. By setting an emergency stop button, the equipment can be stopped in time when a malfunction occurs, reducing damage to the equipment and protecting it. Attached Figure Description

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0024] This application discloses an automatic rotor runout detection device.

[0025] Reference Figure 1 and Figure 2An automatic rotor runout detection device includes a worktable 100 and a reference base 200. The worktable 100 supports the entire device and stabilizes it. The bottom of the reference base 200 is fixedly mounted on the worktable 100 with bolts to stabilize the reference base 200. The reference base 200 is used to place a positioning motor rotor so that the motor rotor can rotate on the reference base 200. A rotary power mechanism 300 is provided on the worktable 100 to drive the motor rotor to rotate, which facilitates the coaxiality detection of the rotor. A detection mechanism 400 is provided on the worktable 100 to detect the runout of the rotor during rotation. The rotary power mechanism 300 includes a base 310 and a pair of slide rails 320. The bottom of the base 310 is fixedly connected to the top of the worktable 100, so that the worktable 100 supports the base 310. The top of the base 310 is fixedly connected to the bottom of the slide rails 320, so that the base 310 stably supports the slide rails 320. The pair of slide rails 320 are arranged opposite to each other on the base 310. A forward / reverse cylinder 340 is provided on the base 310. The bottom of the forward / reverse cylinder 340 is fixedly connected to the top of the base 310, and the forward / reverse cylinder 340 is located between the two slide rails 320. A push plate 350 is fixedly connected to the output end of the forward / reverse cylinder 340. The push plate 350 is in the shape of an inverted L, so that the forward / reverse cylinder 340 drives the push plate 350 to push the push plate 350 to push the push plate 320 to push the push plate 340 to push the push plate 35 ... The push plate 350 moves, and a slide plate 330 is fixedly connected to the end of the push plate 350 away from the forward and backward cylinder 340. The bottom of the slide plate 330 is slidably connected to the slide rail 320, so that the push plate 350 drives the slide plate 330 to move along the slide rail 320. Both ends of the top of the push plate 350 and the top of the slide plate 330 are rotatably connected to pulleys 360, and the pulleys 360 form a triangular shape. A belt 370 is sleeved and connected on the surface of the pulleys 360, so that the belts 370 are connected in a triangle, so that the tension of the belts 370 is stable. A driving component 380 is provided at the bottom of the pulley 360 at one end of the slide plate 330. The driving component 380 is installed at the bottom of the slide plate 330 and drives the pulley 360 to rotate. The testing mechanism 400 includes a lever testing head 410 and a Keyence testing head 420. The lever testing head 410 is detachably mounted on the surface of the reference base 200, and one side of the lever testing head 410 is embedded in the reference base 200. One end of the lever testing head 410 inside the rotor contacts the inner wall of the rotor, allowing the lever testing head 410 to detect and transmit minute runouts of the inner wall of the rotor. The bottom of the lever testing head 410 is connected to the testing end of the Keyence testing head 420 via a lever, allowing the Keyence testing head 420 to detect amplified runouts transmitted by the lever testing head 410. The end of the Keyence testing head 420 away from the lever testing head 410 is connected to a touch screen 430 via a wire. The bottom of the touch screen 430 is fixedly connected to the worktable 100, allowing the touch screen 430 to display and analyze the values ​​transmitted by the Keyence testing head 420, thereby determining the coaxiality of the inner wall of the rotor.

[0026] The above scheme uses a belt 370 on a rotating power mechanism 300 to drive the rotor on a reference base 200 to rotate. When the rotor rotates, it contacts the lever detection head 410 on the detection mechanism 400. The lever detection head 410 amplifies the rotor's runout through the lever principle. Combined with the Keyence detection head 420, the Keyence detection head 420 detects the runout amplified by the lever detection head 410 and transmits the runout value to the touch screen 430 for real-time display. This detects the coaxiality of the rotor without the need for manual rotation or detection, reducing human intervention and significantly improving detection efficiency. The system automatically detects runout, replacing manual reading and identification, and can complete the detection in one go, thus shortening detection time and improving production efficiency.

[0027] refer to Figure 2 The slide plate 330 includes a pair of sliders 331 and a support plate 332. The sliders 331 are slidably connected to the slide rails 320, and the top of the sliders 331 is fixedly connected to the bottom of the support plate 332. The pulley 360 and the drive component 380 are both mounted on the support plate 332, so that the support plate 332 provides stable support. By having the pair of sliders 331 cooperate with the two slide rails 320 on both sides respectively, a symmetrical two-point support is formed, which can effectively limit the lateral tilt or sway of the support plate 332 during the sliding process, ensure that the slide plate 330 moves in a straight line along the slide rails 320, avoid the change of the contact position between the pulley 360 and the rotor due to sliding deviation, ensure the stability of the rotational power transmission, and provide a precise motion reference for jump detection.

[0028] refer to Figure 3The reference base 200 includes a support sleeve 210, a bearing 220, and a reference steel sleeve 230. The support sleeve 210 is bolted to the worktable 100, providing stable support for the bearing 220 and the reference steel sleeve 230. The outer surface of the bearing 220 is fixedly connected to the inner surface of the support sleeve 210, and the inner surface of the bearing 220 is fixedly connected to the surface of the reference steel sleeve 230, allowing the reference steel sleeve 230 to rotate. As the component directly contacting the rotor, the reference steel sleeve 230 has high surface precision and can provide a stable bearing for the rotor. It provides a precise support reference; the support sleeve 210, through its fixed connection with the worktable 100, provides a stable mounting base for the entire reference seat 200, reducing shaking or displacement during the testing process. The bearing 220 allows the reference steel sleeve 230 to rotate flexibly relative to the support sleeve 210. When the rotor is driven to rotate by the rotating power mechanism 300, the reference steel sleeve 230 can rotate synchronously with the rotor, avoiding sliding friction between the rotor and the reference seat 200, which reduces wear on the rotor surface and lowers rotational resistance, ensuring the smoothness of rotor rotation.

[0029] refer to Figure 4 The bottom of the Keyence detection head 420 is fixedly connected to a support base 440. The bottom of the support base 440 is fixedly connected to the worktable 100, and the support base 440 is U-shaped. The Keyence detection head 420 is located in the groove on the support base 440, so that the support base 440 provides stable support for the Keyence detection head 420, preventing the Keyence detection head 420 from shifting its position due to its own weight or equipment vibration. This ensures that the cooperation of the other lever detection heads 410 is always accurate, reduces the measurement error caused by the shaking of the Keyence detection head 420, and ensures the stability and reliability of the detection data.

[0030] refer to Figure 4 An emergency stop button 500 is installed on the workbench 100. The emergency stop button 500 is connected to the forward / reverse cylinder 340 and the drive component 380 via wires, so that the emergency stop button 500 can control the forward / reverse cylinder 340 and the drive component 380 to stop suddenly. Here, the drive component 380 refers to the drive motor, which drives the pulley 360 to rotate. By setting up the emergency stop button 500, the operator can be provided with a direct means to quickly stop the operation of the equipment. When the rotor jams, parts collide, or the belt 370 malfunctions during the operation of the equipment, the operation of the equipment can be stopped in time, protecting the equipment and avoiding damage.

[0031] The implementation principle of this application embodiment is as follows: In implementation, the rotor is placed on the reference base 200, and the shaft on the rotor is fixed to the reference steel sleeve 230 on the reference base 200. Then, the drive component 380 on the slide plate 330 is activated. The drive component 380 drives the pulley 360 on the slide plate 330 to rotate, and the pulley 360 drives the belt 370 to rotate. At the same time, the forward and backward cylinder 340 is activated. The forward and backward cylinder 340 pushes the push plate 350 to move. The push plate 350 drives the slide plate 330 to move on the slide rail 320, so that the slide plate 330 moves closer to the rotor. The belt 370 on the slide plate 330 moves closer and rotates, so that the belt 370 rotates with the rotor. When the rotor contacts the reference seat 200, the forward / reverse cylinder 340 stops, and the belt 370 drives the rotor to rotate. When the inner wall of the rotor rotates, it contacts the lever detection head 410, which transmits the micro-runout of the inner wall of the rotor during rotation. The lever on the lever detection head 410 amplifies the micro-runout, and the Keyence detection head 420 detects the transmitted runout. Then, the Keyence detection head 420 transmits the value to the touch screen 430 for display and analysis, thereby automatically detecting the runout of the rotor, replacing manual reading and identification. This allows for a one-time detection, shortening the detection time and improving production efficiency.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
