During the test, this can lead to issues such as overheating of the coupling, fatigue damage, and accelerated wear. In severe cases, at high speeds, the vibration amplitude of the coupling on the motor and the dynamometer may exceed the limit, affecting the service life of the test bench and the stability and safety of the test process.

[0024] In related technologies, when setting up a motor performance test bench, a motor adapter plate is needed to connect the motor to the test bench and connect the motor output shaft to the coupling on the dynamometer load shaft. During installation, the motor needs to be installed on the adapter plate first, and then the adapter plate is installed on the test bench. Therefore, the assembly position accuracy between the motor and the adapter plate will directly affect the coaxiality accuracy between the motor output shaft and the dynamometer load shaft.
[0025] However, during the installation of the motor and the adapter plate, installation errors and / or machining errors may cause deviations in the alignment of the motor and the adapter plate after assembly. This results in a significant deviation in the coaxiality between the motor output shaft and the dynamometer load shaft after the adapter plate is installed on the test bench. During the test, this can lead to issues such as overheating of the coupling, fatigue damage, and accelerated wear. In severe cases, at high speeds, the vibration amplitude of the coupling on the motor and the dynamometer may exceed the limit, affecting the service life of the test bench and the stability and safety of the test process.
[0026] To address the aforementioned issues, this application provides an alignment auxiliary system for a motor and an adapter board, which can detect the alignment of the motor and the adapter board, thereby assisting in alignment.
[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0028] like Figures 1 to 4 As shown in the figure, this application provides a motor and adapter plate alignment auxiliary system, including a motor (not shown), an adapter plate 1 and a motor and adapter plate alignment auxiliary device. The motor and adapter plate alignment auxiliary device includes a base 2, a support platform 3 and a displacement detector 4.
[0029] The base 2 serves as a supporting structure, and the support platform 3 is rotatably mounted on the base 2. The support platform 3 is used to install the adapter plate 1 connected to the motor. Specifically, the motor can be fixedly mounted on the adapter plate 1 first, and then the adapter plate 1 can be fixedly mounted on the support platform 3. When the support platform 3 rotates relative to the base 2, it can drive the adapter plate 1 and the motor to rotate synchronously.
[0030] The displacement detector 4 is fixedly mounted on the base 2, with its detection end facing the output shaft of the motor. It is used to detect the displacement of the motor's output shaft during rotation of the support platform 3 and output displacement data. This displacement data can be used to determine the coaxiality deviation between the motor's output shaft and the adapter plate 1.
[0031] The base 2 refers to the basic frame supporting the entire device, which can be implemented using a welded metal frame. Its function is to provide stable support for the rotating component 8 and the detector. The bottom of the base 2 can also be equipped with casters 14 to facilitate the movement of the device in multiple test chambers. The support platform 3 refers to the component that mounts and drives the adapter plate 1 to rotate. It can be a plate-like structure, and its rotation axis coincides with the theoretical centering axis of the motor and the adapter plate 1. The support platform 3 can be rotated relative to the base 2 manually or by a drive device. The displacement detector 4 measures the radial displacement of the motor's output shaft as the support platform 3 rotates. The displacement detector 4 can be implemented using a laser displacement sensor or a contact probe, such as a dial indicator, and its installation position is such that the detection direction is perpendicular to the axis of the output shaft.
[0032] Specifically, the displacement detector 4 continuously collects displacement data on the surface of the output shaft during the rotation of the support platform 3. By analyzing the displacement data at different rotation angles, the theoretical offset of the output shaft from the centerline of the adapter plate 1 can be calculated. This offset is the quantitative index of coaxiality deviation, which can be directly used to guide assembly adjustments. The method used to calculate the coaxiality deviation between the motor's output shaft and the adapter plate 1 based on the displacement data is similar to the method used to calculate radial runout error.
[0033] The above solution can detect the coaxiality deviation of the motor and adapter plate 1 during the assembly stage, avoid the subsequent testing risks caused by assembly errors, and guide the adjustment operation through deviation data. It can significantly improve the assembly accuracy, reduce abnormal wear of the coupling and excessive vibration during testing, and ensure the stability and safety of the test bench operation.
[0034] Specifically, such as Figures 1 to 4 As shown, the adapter plate 1 has a first through hole 12 through which the output shaft of the power supply passes, and the support platform 3 has a second through hole 13 through which the output shaft of the power supply passes. The first through hole 12 and the second through hole 13 are coaxially arranged. The axis of rotation of the support platform 3 relative to the base 2 is the central axis of the first through hole 12 and the second through hole 13.
[0035] The coaxiality deviation between the motor's output shaft and the adapter plate 1 refers to the coaxiality deviation between the motor's output shaft and the first through hole 12, that is, the offset distance between the central axis of the motor's output shaft and the central axis of the first through hole 12. When the motor and the adapter plate 1 are in the center position, theoretically the motor's output shaft and the first through hole 12 are coaxially set.
[0036] When aligning the motor and adapter plate 1 according to the calculated coaxiality deviation between the motor's output shaft and the adapter plate 1, the position of the motor on the adapter plate 1 is moved so that the offset distance between the central axis of the motor's output shaft and the central axis of the first through hole 12 is within the allowable range.
[0037] In related technologies, the adapter plate 1 is installed on the mating surface of the motor (the end face of the output shaft). There are typically three installation methods: the first is installation via pin holes, the second is installation via the stop face of the motor mating surface, and the third is installation via bolt holes. The first two installation methods make it impossible to check the deviation between the adapter plate 1 and the output shaft after installation. Deviations in the machining of the pin holes or stop face of the adapter plate 1 may lead to excessive deviation, accelerating wear during testing. In the third installation method, directly aligning the bolt holes results in a large deviation between the center axis of the adapter plate 1 and the center axis of the motor output shaft. Furthermore, during torque application after bolt installation, the motor may shift, causing it to deviate from its initial deviation state, which cannot be checked. This leads to excessive vibration between the motor and the test bench after the test bench is erected, accelerating damage to the test bench coupling.
[0038] The alignment auxiliary device for the motor and adapter plate in this embodiment can check the positional deviation between the adapter plate 1 and the motor output shaft for the first and second installation methods described above, promptly detect machining errors in the adapter plate 1, and replace it with a qualified adapter plate 1, or change the installation scheme to the third installation method. For the third installation method, the motor and adapter plate 1 can be aligned and adjusted according to the calculated coaxiality deviation between the motor output shaft and the adapter plate 1. Specifically, the bolts can be loosened first, then the position of the motor on the adapter plate 1 can be moved according to the detected deviation value, and then the bolts can be tightened to ensure that the offset distance between the central axis of the motor output shaft and the central axis of the first through hole 12 is within the allowable range, thereby achieving auxiliary alignment of the motor output shaft and the adapter plate 1. At the same time, the deviation after adjustment can be checked and adjusted again.
[0039] To improve detection efficiency and result accuracy, and to achieve automatic calculation of deviation, in some embodiments, the alignment auxiliary device between the motor and the adapter plate also includes a data analysis unit. The displacement detector 4 is communicatively connected to the data analysis unit, which is configured to calculate the coaxiality deviation between the output shaft of the motor and the adapter plate 1 based on the displacement data collected by the displacement detector 4 at different rotation angles of the bearing platform 3.
[0040] The data analysis unit refers to a computing module with data processing capabilities, which can be implemented using a microcontroller, embedded processor, industrial control computer, or host computer. It receives data transmitted from the displacement detector 4 and calculates the coaxiality deviation. The communication connection between the displacement detector 4 and the data analysis unit refers to the establishment of a data interaction channel between them, which can be achieved through a wired interface or wireless transmission, ensuring that displacement data can be transmitted to the computing unit in real time.
[0041] Specifically, the displacement detector 4 collects radial displacement data of the motor output shaft at different angles in real time during the rotation of the support platform 3, and sends the data packets to the data analysis unit. The data analysis unit performs coordinate transformation processing on the multi-angle displacement data (for example, transforming the measured values into points on polar coordinates). Based on the measured values, it can fit the outer circumferential contour of the motor output shaft using the least squares method, thereby obtaining the axis of the motor output shaft. This axis is then compared spatially with the preset theoretical axis of the adapter plate 1 to calculate the coaxiality deviation. Alternatively, other simpler but less accurate methods can be used to calculate the coaxiality deviation, such as using the difference between the measured maximum and minimum displacement data as the coaxiality deviation value.
[0042] The integrated data analysis unit avoids the tediousness and potential errors of manual data processing, and realizes full automation from data acquisition to result analysis, greatly improving the efficiency and accuracy of alignment detection.
[0043] To ensure the high repeatability and accuracy of the installation position of the adapter plate 1 on the support platform 3, in some embodiments, such as Figure 2 As shown, a limiting groove 5 and a limiting boss 6 are provided between the support platform 3 and the adapter plate 1. The limiting boss 6 is embedded in the limiting groove 5 to limit the position of the support platform 3 and the adapter plate 1. In the figure, the limiting groove 5 is provided on the support platform 3, and the limiting boss 6 is provided on the adapter plate 1. In other embodiments, the limiting groove 5 may be provided on the adapter plate 1, while the limiting boss 6 may be provided on the support platform 3.
[0044] The limiting groove 5 refers to a recessed structure on the support platform 3 or the adapter plate 1, which can be a rectangular groove, a circular groove, or an irregularly shaped groove. Its dimensions match the limiting boss 6, and it is used to limit the horizontal displacement of the adapter plate 1. The limiting boss 6 refers to a protruding structure on the adapter plate 1 or the support platform 3, which can be a cylindrical, square, or trapezoidal protrusion that complements the shape of the limiting groove 5. After being embedded in the limiting groove 5, it can eliminate the relative sliding between the adapter plate 1 and the support platform 3. The limiting groove 5 and the limiting boss 6 can ensure the coaxiality of the adapter plate 1 and the support platform 3, thereby ensuring the accuracy of the position of the central axis of the adapter plate 1 as the measurement reference.
[0045] Specifically, when the adapter plate 1 is installed on the support platform 3, the limiting boss 6 is forcibly embedded in the limiting groove 5, so that the position of the adapter plate 1 in the horizontal plane is uniquely determined and cannot be laterally offset. Then, the adapter plate 1 can be fastened to the support platform 3 with bolts. When the support platform 3 rotates, the overall rotation trajectory of the adapter plate 1 and the motor is constrained to move around the mating axis of the limiting groove 5 and the limiting boss 6, thereby eliminating the cumulative error caused by the installation gap and ensuring the accuracy of the measurement reference.
[0046] During the testing process, motor vibration may cause distortion of displacement data. To prevent motor vibration during rotational testing, in some embodiments, such as... Figures 1 to 4 As shown, the support platform 3 is equipped with multiple fixing clamps 7, which are arranged around the motor to hold it in place. These clamps can be quick-release clamps, and they are arranged circumferentially around the motor. By operating these clamps, they are pressed against the motor housing, thereby firmly fixing the motor to the support platform 3 from multiple directions. This multi-point fixing method effectively suppresses any possible loosening and vibration, ensuring the absolute stability of the motor during the testing process, thus guaranteeing the authenticity and reliability of the collected displacement data.
[0047] The multiple fixing clamps 7 refer to multiple independent clamping devices, which can be implemented using mechanical clamps or pneumatic clamps, enhancing the fixing effect on the motor through multi-point contact. The "around the motor" arrangement refers to the clamps being distributed circumferentially around the motor, which can be achieved using a ring arrangement or a symmetrical layout, ensuring that the clamping force is evenly applied to the outer wall of the motor and avoiding localized stress concentration.
[0048] Specifically, the fixing clamps 7 are installed on the edge area of the support platform 3 and are distributed circumferentially around the motor mounting position. When the motor is placed on the support platform 3, the positions of the multiple fixing clamps 7 can be adjusted to contact the outer wall of the motor and clamped by the locking mechanism. During the rotation of the support platform 3, the fixing clamps 7 continuously abut against the outer wall of the motor, forming a stable constraint force to prevent the motor from displacing due to inertia or vibration.
[0049] In addition, during installation, after adjusting the coaxiality of the motor and the adapter plate 1, before tightening the motor and the adapter plate 1 with bolts, the motor can be fixed with the fixing clamp 7 first, and then tightened with bolts. This can avoid the situation where the motor and the adapter plate 1 have a axial deviation after the bolts are installed, which is inconsistent with the deviation state before tightening.
[0050] To achieve smooth and stable rotation of the bearing platform 3, such as Figure 2 and Figure 4 As shown, in some embodiments, a rotating component 8 is provided on the base 2, and the support platform 3 is rotatably connected to the base 2 via the rotating component 8. The rotating component 8 can be a slewing bearing, with its outer ring fixedly connected to the support platform 3 and its inner ring fixedly connected to the base 2. With this structure, the support platform 3 can easily and smoothly rotate 360 degrees relative to the base 2, thanks to the low friction and high precision characteristics of the slewing bearing. The introduction of the rotating component 8 makes the operation of simulating rotation and acquiring multi-angle displacement data more effortless and accurate, avoiding measurement errors caused by uneven or instable rotation.
[0051] To provide a stable mounting base for displacement detector 4, such as Figure 2As shown, in some embodiments, the alignment auxiliary device between the motor and the adapter plate further includes a detector mounting base 9 disposed on the base 2, and a displacement detector 4 disposed on the detector mounting base 9. The detector mounting base 9, as an independent component, is fixed to a preset position on the base 2 by means of bolts or other methods. The displacement detector 4 is reliably fixed to the mounting base through its own mounting interface. The presence of the detector mounting base 9 eliminates the need for the displacement detector 4 to be directly mounted on the base 2, allowing for more flexible selection of its mounting position, and also providing a structural basis for possible subsequent position fine-tuning.
[0052] To accommodate the differences in output shaft diameter among different motor models, such as Figure 2 As shown, in some embodiments, the base 2 is provided with an adjustment plate 10, and the adjustment plate 10 is provided with a plurality of mounting positions for mounting the detector mounting base 9. The position of the detector mounting base 9 in the horizontal direction can be adjusted through the plurality of mounting positions.
[0053] The mounting position can be a positioning hole formed on the adjustment plate 10. The adjustment plate 10 refers to a plate-like structure fixed on the base 2 to support the detector mounting base 9. Specifically, it can be a metal plate or a composite material plate with positioning holes. Its function is to provide a horizontal position adjustment base for the detector mounting base 9. The positioning holes are arranged in an array or along a specific trajectory.
[0054] Specifically, the adjusting plate 10 can be fixed to the surface of the base 2 by bolts or welding, and multiple mounting positions are distributed on it along the horizontal direction. The detector mounting base 9 is connected to the selected mounting position by fasteners, and the horizontal position of the detector mounting base 9 can be changed by changing the mounting position. For example, when the diameter of the motor output shaft is large, the detector mounting base 9 can be selected at a mounting position close to the edge of the base 2, so that the detection end of the displacement detector 4 is aligned with the outer edge of the output shaft; when the diameter of the output shaft is small, the detector mounting base 9 can be selected at a mounting position close to the center of the base 2. Through the combination of the adjusting plate 10 and the mounting positions, the horizontal position of the detector mounting base 9 can be adjusted to adapt to the detection requirements of different types of motors.
[0055] To accommodate the differences in output shaft length among different motor models, such as Figure 2 As shown, in some embodiments, the detector mounting base 9 is provided with a telescopic rod 11 that can extend and retract relative to the detector mounting base 9 in the vertical direction, and the displacement detector 4 is disposed on the telescopic rod 11.
[0056] The detector mounting base 9 may also be equipped with locking bolts. When the telescopic rod 11 extends or retracts relative to the detector mounting base 9, the telescopic rod 11 and the detector mounting base 9 are locked together by the locking bolts.
[0057] Specifically, when the length of the motor output shaft changes, the operator extends or shortens the telescopic rod 11, causing the displacement detector 4 to move synchronously in the vertical direction. For example, when it is necessary to detect the motor output shaft at a higher installation position, the telescopic rod 11 can be moved upwards so that the detection end of the displacement detector 4 is aligned with the surface of the output shaft; when detecting a longer motor output shaft, the telescopic rod 11 is moved downwards to lower the detector height. During this process, the linear motion characteristics of the telescopic rod 11 ensure that the displacement detector 4 is always adjusted along the vertical axis, avoiding displacement of the detection reference due to tilting movement.
[0058] In some embodiments, the base 2 is provided with movable wheels 14 at its bottom to facilitate movement of the device in multiple test chambers.
[0059] The alignment adjustment process using the alignment auxiliary system for the motor and adapter plate in this embodiment is as follows: 1. Connect the motor and adapter plate 1 together with bolts to form a whole. After connection, it is ready to be placed on the platform. 2. The motor and adapter plate 1 connected together are positioned on the support platform 3 by the limiting boss 6 of the adapter plate 1 and the limiting groove 5 on the support platform 3. 3. Check the installation status of the motor and fix the motor around its perimeter using the fixing clamp 7 to prevent vibration; 4. By adjusting the vertical position of the telescopic rod 11 and the horizontal position of the detector mounting base 9, the position of the displacement detector 4 is changed so that the displacement detector 4 and the motor output shaft are in a suitable position, which can accurately receive the feedback signal from the wall surface of the motor output shaft. At this time, the motor output shaft, the adapter plate 1, and the displacement detector 4 are all in a detectable state. 5. By rotating the rotating component 8, the bearing platform 3 is driven to rotate, which in turn drives the adapter plate 1 and the motor to rotate, thus realizing the rotation of the motor output shaft relative to the displacement detector 4. Then, the reading of the displacement detector 4 is recorded, and the offset direction and offset distance of the motor output shaft relative to the adapter plate 1 can be fed back through analysis. 6. Based on the offset direction and offset distance of the motor output shaft relative to the adapter plate 1, the direction and displacement of the motor can be obtained for subsequent adjustments. After adjustment, repeating step 5 can achieve a high-precision installation state.
