Description

Technical Field

[0001] This application relates to the technical field of rotor magnetization and magnetic measurement equipment, and in particular to an automatic magnetization and magnetic measurement machine. Background Technology

[0002] The rotor is the core rotating component of a permanent magnet motor, and the magnetic properties of its internal permanent magnets directly determine the motor's output torque, efficiency, and operational stability. During motor manufacturing, rotor magnetization is an indispensable and crucial process. By applying a strong, instantaneous magnetic field to the permanent magnets inside the rotor, it acquires the necessary remanence, ensuring the motor can generate its operating magnetic field correctly. Simultaneously, after magnetization, the rotor's magnetic properties must be tested to confirm magnetization saturation, uniform pole distribution, and adequate magnetic field strength, thereby ensuring product quality.

[0003] In existing technologies, rotor magnetization and magnetic property testing are typically arranged as two independent processes. Operators first magnetize the rotor using separate magnetization equipment, and then transfer the magnetized rotor to a dedicated testing station or test bench for magnetic property testing. In this process, some highly automated production lines have adopted robotic arms or conveyor belts to automatically transfer the rotor between the magnetization and testing equipment, but magnetization and magnetic property testing are still handled by two separate devices.

[0004] When the rotor is transferred between the magnetization equipment and the testing equipment, it needs to be re-clamped and repositioned. Since there is an inevitable deviation in the positioning reference between the two clamping, it is difficult to keep the circumferential angle and axial position of the rotor consistent. This results in a misalignment error between the magnetic field data collected by the testing equipment and the actual magnetic pole distribution of the rotor, affecting the accuracy of magnetic measurement and the consistency of product judgment. Summary of the Invention

[0005] To address the issue that existing rotor magnetization and magnetization measurement processes are performed on two separate devices, requiring re-clamping and repositioning during rotor transfer, which leads to positioning errors affecting magnetization measurement accuracy, this application provides an automatic magnetization and magnetization measurement machine.

[0006] The automatic magnetization and magnetization tester provided in this application adopts the following technical solution: An automatic magnetizing and testing machine includes a cabinet. A slide rail is provided inside the cabinet, and a mounting base is slidably mounted on the slide rail along the length of the cabinet. A rotating platform for placing a rotor is rotatably mounted on the mounting base. A magnetizing station and a testing station are sequentially arranged inside the cabinet along the length of the slide rail. A movable seat is provided at the magnetizing station, and a magnetizing cylinder is mounted on the movable seat. A testing seat is provided at the testing station, and a testing probe is mounted on the testing seat. The cabinet also includes a first movable component for driving the movable seat to move vertically and a second movable component for driving the testing seat to move vertically.

[0007] By adopting the above technical solution, the rotor is placed on a rotating platform. The mounting seat moves the rotor to the magnetization station, and the moving seat moves the magnetization cylinder downwards to cover the outer circumference of the rotor. The magnetization cylinder magnetizes the rotor. After magnetization, the mounting seat moves along the slide rail to the magnetic measurement station. The test seat moves the test probe downwards to the circumference of the rotor, and the rotating platform rotates the rotor. The test probe measures the magnetization of the rotor. The magnetization and magnetic measurement processes are integrated into the same equipment. The reciprocating movement of the mounting seat on the slide rail realizes the automatic transfer of the rotor between the magnetization and magnetic measurement stations. There is no need for manual handling and re-clamping. This avoids the positioning error caused by repositioning when the rotor is transferred between the magnetization and magnetic measurement processes in traditional separate equipment, improves the magnetic measurement accuracy, and completes magnetization and magnetic measurement continuously in the same equipment. This reduces the waiting time for the rotor to be transferred between different equipment, greatly improves production efficiency, reduces labor costs, and realizes the integrated automatic operation of rotor magnetization and magnetic measurement.

[0008] Preferably, a horizontally arranged lead screw is rotatably installed inside the cabinet. The lead screw is arranged along the length direction of the slide rail. The mounting seat is sleeved on the outer periphery of the lead screw. The mounting seat and the lead screw are threadedly connected. A first motor is installed inside the cabinet. The output end of the first motor is coaxially and fixedly connected to the end of the lead screw.

[0009] By adopting the above technical solution, the first motor is started, which drives the horizontal lead screw to rotate. The horizontal lead screw is engaged with the screw drive of the mounting base, which drives the mounting base to move smoothly along the length of the slide rail, realizing the precise transport of the rotor between the magnetization station and the magnetization measurement station. The screw drive has a self-locking characteristic, which can keep the position of the mounting base stable after the motor stops rotating, ensuring that the rotor is accurately positioned during the magnetization and magnetization measurement process, realizing the rapid positioning and station switching of the rotor, and improving the overall working efficiency of the equipment.

[0010] Preferably, a drive wheel and a timing wheel are rotatably mounted on the mounting base, a timing belt is wound around the outer periphery of the drive wheel and the timing wheel, the rotating table is coaxially and fixedly connected to the timing wheel, and a second motor is mounted on the mounting base, the output end of the second motor is coaxially and fixedly connected to the drive wheel.

[0011] By adopting the above technical solution, the second motor is started, which drives the drive wheel to rotate. The drive wheel drives the synchronous wheel to rotate synchronously through the synchronous belt. The synchronous wheel drives the rotating table and the rotor placed on it to rotate synchronously, realizing the uniform rotation of the rotor. This allows the test probe to continuously scan and measure the magnetic field strength at various positions around the rotor. The synchronous belt drive has the advantages of smooth transmission, low noise, and no slippage loss, which can ensure the stability and uniformity of the rotation speed of the rotating table and improve the magnetic measurement accuracy.

[0012] Preferably, the movable component includes a vertically arranged vertical guide rod and a vertical lead screw. The vertical lead screw is rotatably installed inside the cabinet. The movable seat is sleeved on the outer periphery of the vertical guide rod and the vertical lead screw. The movable seat and the vertical lead screw are threadedly connected. A third motor is installed on the cabinet. The output end of the third motor is coaxially and fixedly connected to the top end of the vertical lead screw.

[0013] By adopting the above technical solution, the third motor is started, which drives the vertical lead screw to rotate. The vertical lead screw is threadedly driven with the moving seat, and the vertical guide rod provides vertical sliding guidance for the moving seat, so that the moving seat can move smoothly in the vertical direction. This achieves precise control of the height of the magnetizing cylinder and keeps the position of the magnetizing cylinder stable after the motor stops rotating, ensuring that the magnetizing cylinder is always covered on the outer periphery of the rotor during the magnetization process.

[0014] Preferably, a first ejector pin is vertically slidably installed inside the cabinet, and a first cylinder is installed inside the cabinet. The bottom end of the piston rod of the first cylinder is fixedly connected to the top end of the first ejector pin. The first ejector pin passes through the magnetizing cylinder and is coaxially arranged with the magnetizing cylinder. The bottom end of the first ejector pin can abut against the top of the rotor shaft.

[0015] By adopting the above technical solution, when the piston rod of the first cylinder extends, it drives the ejector pin one to move vertically downward. The bottom end of the ejector pin one abuts against the top of the rotor shaft, applying axial clamping force to the rotor and reliably pressing the rotor onto the rotating table. This prevents the rotor from axially shifting or radially deviating due to the strong electromagnetic force during the magnetization process, ensuring the stability of the rotor position and the consistency of the magnetization effect during the magnetization process.

[0016] Preferably, the second movable component includes a second cylinder, a support base is installed inside the cabinet, the second cylinder is installed on the support base, the bottom end of the piston rod of the second cylinder is fixedly connected to the test base, a second ejector pin is vertically slidably installed inside the cabinet, a third cylinder is installed inside the cabinet, and the bottom end of the second ejector pin can abut against the top of the rotor shaft.

[0017] By adopting the above technical solution, the second cylinder drives the test seat to move vertically, which in turn moves the test probe downward to the circumference of the rotor, thereby achieving precise control of the distance between the test probe and the rotor. This ensures that the distance between the probe and the rotor surface remains within a predetermined range during magnetic measurement, thus improving the accuracy of magnetic measurement. The second pin moves downward under the drive of the third cylinder and abuts against the top of the rotor shaft, applying axial clamping force to the rotor. This ensures that the rotor will not axially move during magnetic measurement, guaranteeing the smoothness of rotor rotation and improving the accuracy and reliability of the magnetic measurement data.

[0018] Preferably, the test stand includes a test platform, the bottom end of the piston rod of the second cylinder is fixedly connected to the top surface of the test platform, an adjusting block is fixed to the side of the test platform, an adjusting sleeve is sleeved on the outer periphery of the adjusting block, the adjusting sleeve can move along the length direction of the test platform, a locking member is provided on the adjusting sleeve for fixing the adjusting sleeve and the adjusting block, an adjusting screw and an adjusting rod are rotatably installed on the side of the adjusting sleeve away from the adjusting block, a fine-tuning block is sleeved on the outer periphery of the adjusting screw and the adjusting rod, the test probe is installed on the fine-tuning block, and the fine-tuning block is threadedly connected to the adjusting screw.

[0019] By adopting the above technical solution, the adjusting sleeve can move along the length of the test bench and be fixed to different positions of the adjusting block by the locking component, so as to achieve coarse adjustment of the test probe in the horizontal direction; the adjusting screw and the fine-adjusting block are threadedly engaged, and by rotating the adjusting screw, the fine-adjusting block can be moved precisely along the guide direction of the adjusting rod, so as to achieve fine adjustment of the test probe in the horizontal direction, so that the test probe can be accurately positioned to the predetermined measurement position on the circumference of the rotor, ensuring that the distance between the probe and the rotor surface is precisely controllable, thereby improving the magnetic measurement accuracy, and at the same time, it can be adapted to rotors of different sizes and specifications.

[0020] Preferably, the locking component includes a locking pin, the side of the adjusting block has a plurality of positioning holes, the plurality of positioning holes are equally spaced along the length direction of the test bench, the side of the adjusting sleeve has a locking hole, and the locking pin can pass through the locking hole and be inserted into the positioning hole.

[0021] By adopting the above technical solution, the locking pin passes through the locking hole on the side of the adjusting sleeve and is inserted into the positioning hole on the side of the adjusting block, thereby fixing the adjusting sleeve and the adjusting block relative to each other. This achieves precise locking of the adjusting sleeve at different positions along the length of the test bench. Operators can select the corresponding positioning hole for fixing according to the rotor of different sizes, thus improving the equipment's adaptability to rotors of different specifications.

[0022] Preferably, the top of the support is equipped with a protective cover with an opening at the bottom, and the test probe can move upward into the protective cover.

[0023] By adopting the above technical solution, when the magnetic measurement is completed or the equipment is in standby mode, the test holder moves the test probe upward into the protective cover. The protective cover protects the test probe from accidental collisions that could damage it when the equipment is stopped or not in operation, thus extending the service life of the test probe. At the same time, the protective cover can also prevent dust, debris and other impurities from contaminating the sensing surface of the test probe, ensuring the accuracy of the magnetic measurement.

[0024] In summary, this application includes at least one of the following beneficial technical effects: The rotor is placed on a rotating platform. The mounting base moves the rotor to the magnetization station. The moving base moves the magnetization cylinder downwards and covers the outer circumference of the rotor. The magnetization cylinder magnetizes the rotor. After magnetization, the mounting base moves along the slide rail to the magnetic measurement station. The test base moves the test probe downwards to the circumference of the rotor. The rotating platform rotates the rotor, and the test probe measures the magnetism of the rotor. The magnetization and magnetic measurement processes are integrated into the same equipment. The reciprocating movement of the mounting base on the slide rail realizes the automatic transfer of the rotor between the magnetization and magnetic measurement stations. There is no need for manual handling and re-clamping. This avoids the positioning error caused by repositioning when the rotor is transferred between the magnetization and magnetic measurement processes in traditional separate equipment, and improves the magnetic measurement accuracy. Magnetization and magnetic measurement are completed continuously in the same equipment, reducing the waiting time for the rotor to be transferred between different equipment, greatly improving production efficiency, reducing labor costs, and realizing the integrated automatic operation of rotor magnetization and magnetic measurement. Start the third motor, which drives the vertical lead screw to rotate. The vertical lead screw is threadedly driven with the moving seat, and the vertical guide rod provides vertical sliding guidance for the moving seat, so that the moving seat can move smoothly in the vertical direction. This achieves precise control of the height of the magnetizing cylinder and can keep the position of the magnetizing cylinder stable after the motor stops rotating, ensuring that the magnetizing cylinder is always covered on the outer periphery of the rotor during the magnetization process. When the piston rod of the first cylinder extends, it drives the ejector pin one to move vertically downward. The bottom end of the ejector pin one abuts against the top of the rotor shaft, applying axial clamping force to the rotor and reliably pressing the rotor onto the rotating table. This prevents the rotor from axially shifting or radially deviating due to the strong electromagnetic force during the magnetization process, ensuring the stability of the rotor position and the consistency of the magnetization effect during the magnetization process.

A first motor 13 is installed inside the cabinet 1, and the output shaft of the first motor 13 is coaxially and fixedly connected to the end of the lead screw 12. When the first motor 13 is started, it drives the lead screw 12 to rotate in either the forward or reverse direction. The lead screw 12, through threaded transmission, drives the mounting seat 2 to move smoothly along the length of the slide rail 11, achieving precise transport of the mounting seat 2 between different positions on the slide rail 11.

[0034] Reference Figure 2 and Figure 3A rotating platform 21 is rotatably mounted on the mounting base 2. The top surface of the rotating platform 21 is used to place the rotor to be magnetized and measured. A drive wheel 22 and a synchronous wheel 23 are rotatably mounted on the mounting base 2. A synchronous belt 24 is wound around the outer circumference of the drive wheel 22 and the synchronous wheel 23. The synchronous wheel 23 is coaxially and fixedly connected to the rotating platform 21. A second motor 25 is mounted on the mounting base 2. The output shaft of the second motor 25 is coaxially and fixedly connected to the drive wheel 22. When the second motor 25 is started, the second motor 25 drives the drive wheel 22 to rotate. The drive wheel 22 drives the synchronous wheel 23 to rotate synchronously through the synchronous belt 24. The synchronous wheel 23 drives the rotating platform 21 and the rotor placed on it to rotate synchronously and uniformly.

[0035] Reference Figure 2 and Figure 4 Inside the cabinet 1, along the length of the slide rail 11, there are a magnetization station 3 and a magnetization measuring station 4 arranged sequentially. A movable seat 31 is installed at the magnetization station 3, sliding vertically within the cabinet 1. A vertically arranged guide rod 32 is fixedly installed inside the cabinet 1, and a vertically arranged lead screw 33 is also rotatably installed inside the cabinet 1. The movable seat 31 is fitted around the outer periphery of the guide rod 32 and the lead screw 33, and the movable seat 31 and the lead screw 33 are threadedly connected. A third motor 34 is installed on the cabinet 1, and the output shaft of the third motor 34 is coaxially and fixedly connected to the top end of the lead screw 33. When the third motor 34 is started, it drives the lead screw 33 to rotate, and the lead screw 33 drives the movable seat 31 to move smoothly vertically along the guide direction of the guide rod 32 via threaded transmission.

[0036] Reference Figure 2 and Figure 4 A magnetizing cylinder 35 is fixedly mounted on the movable base 31. The magnetizing cylinder 35 has a cylindrical structure and a magnetizing coil is installed inside. The magnetizing cylinder 35 moves vertically synchronously with the movable base 31. When the movable base 31 drives the magnetizing cylinder 35 to move downward to the lowest position, the magnetizing cylinder 35 is sleeved on the outer circumference of the rotor, and the rotor is completely located inside the magnetizing cylinder 35. The magnetizing cylinder 35 magnetizes the rotor.

[0037] Reference Figure 2 and Figure 4 Inside the cabinet 1, a ejector pin 36 is vertically slidable, passing through the interior of the magnetizing cylinder 35 and coaxially arranged with it. The ejector pin 36 can slide freely vertically within the magnetizing cylinder 35 without interfering with each other. A first cylinder 37 is fixedly installed on the top of the cabinet 1, and the bottom end of the piston rod of the first cylinder 37 is fixedly connected to the top end of the ejector pin 36.

[0038] When the first cylinder 37 is activated, the piston rod of the first cylinder 37 extends, causing the ejector pin 36 to move vertically downward. The bottom end of the ejector pin 36 passes through the interior of the magnetizing cylinder 35 and abuts against the top of the rotor shaft placed on the rotating table 21, applying axial clamping force to the rotor and reliably pressing the rotor onto the rotating table 21.

[0039] Reference Figure 2 and Figure 5 At the magnetic measurement station 4, a support base 41 and a test base 5 are provided. A second cylinder 42 is mounted on the support base 41.

Several positioning holes 521 are opened on the side of the adjusting block 52, and the positioning holes 521 are equally spaced along the length of the adjusting block 52. A corresponding locking hole 531 is opened on the side of the adjusting sleeve 53, and a locking pin 54 passes through the locking hole 531. When the adjusting sleeve 53 slides to the desired position, the locking hole 531 aligns with one of the positioning holes 521, and the locking pin 54 passes through the locking hole 531 and is inserted into the corresponding positioning hole 521, thereby fixing the adjusting sleeve 53 and the adjusting block 52 relative to each other.

A fine-tuning block 57 is fitted around the outer periphery of the adjusting screw 55 and the adjusting rod 56, and the fine-tuning block 57 is threadedly connected to the adjusting screw 55. When the adjusting screw 55 is rotated, the fine-tuning block 57 moves precisely along the guide direction of the adjusting rod 56. A test probe 58, a Hall effect sensor, is fixedly mounted on the fine-tuning block 57 to detect the magnetic field strength on the rotor surface. A protective cover 59 with an open bottom surface is installed on the top of the support base 41. When the magnetic measurement is completed or the equipment is in standby mode, the second cylinder 42 drives the test base 5 to move the test probe 58 upward into the interior of the protective cover 59. The protective cover 59 protects the test probe 58 from accidental collisions and damage.

[0041] Reference Figure 2 At the magnetic measurement station 4, a second ejector pin 6 is installed. A third cylinder 61 is fixedly installed inside the cabinet 1. The bottom end of the piston rod of the third cylinder 61 is fixedly connected to the top end of the second ejector pin 6. When the third cylinder 61 is activated, the piston rod of the third cylinder 61 extends, causing the second ejector pin 6 to move vertically downward. The bottom end of the second ejector pin 6 abuts against the top of the rotor shaft placed on the rotating table 21, applying axial clamping force to the rotor to ensure that the rotor rotates smoothly during the magnetic measurement process.

[0042] The implementation principle of an automatic magnetizing and measuring machine according to an embodiment of this application is as follows: The operator places the rotor to be magnetized and measured on the rotating table 21, starts the first motor 13, the first motor 13 drives the horizontal lead screw 12 to rotate, the horizontal lead screw 12 drives the mounting base 2 to move along the slide rail 11 to the magnetizing station 3, so that the rotor is directly below the magnetizing cylinder 35, starts the first cylinder 37, the piston rod of the first cylinder 37 extends and drives the ejector pin 36 to move downward, the bottom end of the ejector pin 36 abuts against the top of the rotor shaft, pressing the rotor tightly on the rotating table 21, then starts the third motor 34, the third motor 34 drives the vertical lead screw 33 to rotate, the vertical lead screw 33 drives the moving seat 31 and the magnetizing cylinder 35 to move downward, so that the magnetizing cylinder 35 covers the outer periphery of the rotor, and the magnetizing cylinder 35 applies a strong magnetic field to the rotor to complete the magnetization.

[0043] After magnetization is complete, the third motor 34 reverses, driving the magnetizing cylinder 35 to move upward and reset. The piston rod of the first cylinder 37 retracts, driving the ejector pin 36 to move upward and releasing the clamping state on the rotor. The first motor 13 restarts, driving the mounting base 2 to move along the slide rail 11 to the magnetic measurement station 4, so that the rotor is located at the measurement position of the test probe 58.

[0044] Start the third cylinder 61. The piston rod of the third cylinder 61 extends and drives the second ejector pin 6 to move downward. The bottom end of the second ejector pin 6 abuts against the top of the rotor shaft, pressing the rotor onto the rotating table 21. Start the second cylinder 42. The piston rod of the second cylinder 42 extends and drives the test seat 5 to move downward, so that the test probe 58 descends to the predetermined measurement position on the circumference of the rotor.

[0045] The second motor 25 is started, which drives the drive wheel 22 to rotate. The drive wheel 22 drives the synchronous wheel 23 and the rotating table 21 to rotate at a constant speed through the synchronous belt 24. The rotating table 21 drives the rotor to rotate synchronously and at a constant speed. The test probe 58 continuously scans and measures the magnetic field strength at various positions around the rotor. The measured signals are transmitted to the external data processing system for analysis and judgment.

[0046] After the magnetization test is completed, the second motor 25 stops rotating, and the piston rod of the second cylinder 42 retracts, causing the test seat 5 to move upward, so that the test probe 58 retracts into the protective cover 59; the piston rod of the third cylinder 61 retracts, causing the ejector pin 6 to move upward, releasing the clamping state on the rotor. The first motor 13 restarts, driving the mounting base 2 to move along the slide rail 11 to the unloading station. The operator removes the rotor that has completed the magnetization test, and the next batch of rotors can be processed.

[0047] The magnetization process and the magnetic measurement process are integrated into the same equipment. The rotor is automatically transferred between the magnetization station 3 and the magnetic measurement station 4 by the reciprocating movement of the mounting base 2 on the slide rail 11. No manual handling or re-clamping is required, realizing the integrated automatic operation of rotor magnetization and magnetic measurement.

[0048] 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.
