Description

Technical Field

[0001] This invention relates to the field of magnetic wheel torque testing technology, and in particular to a magnetic wheel torque testing device, debugging method, and data processing method. Background Technology

[0002] Magnetic wheels, as a device that uses magnetic force for non-contact power transmission, fundamentally avoid the wear problems of traditional mechanical gears. Therefore, they have been widely used in recent years in industrial fields with high cleanliness requirements, such as vacuum environments, cleanrooms, and food and pharmaceutical industries. Common magnetic wheel transmission directions can be divided into three main categories: orthogonal transmission, parallel transmission, and conical transmission. However, current magnetic wheel torque testing equipment on the market is usually designed for a single type of magnetic wheel, using a fixed frame structure. This design requires customized fixtures for different types of magnetic wheels and cannot meet the testing needs of products with multiple specifications. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the first aspect of the present invention provides a magnetic wheel torque testing device capable of testing magnetic wheels of various specifications.

[0004] A second aspect of the present invention also proposes a debugging method.

[0005] A third aspect of the present invention also proposes a data processing method.

[0006] According to a first aspect of the present invention, a magnetic wheel torque testing device includes a base, a first mounting structure, a second mounting structure, and at least two detection structures. The first mounting structure includes a first mounting bracket, a driver, and a drive shaft. The first mounting bracket is disposed on the base, and the drive shaft is rotatably disposed on the first mounting bracket. The driver is connected to the drive shaft and is used to drive the drive shaft to rotate around its own axis. A magnetic drive wheel is passed through the drive shaft. The second mounting structure is disposed on the base and has a connecting block. The detection structure includes a mounting member, a sensor, and a driven shaft. The mounting member is detachably connected to the connecting block, and the sensor is disposed on the mounting member. The detection end of the sensor is connected to the driven shaft, and the driven shaft is used to pass through the magnetic driven wheel. The at least two detection structures include a first detection structure and a second detection structure with different specifications. When the mounting member and the connecting block of the first detection structure are detachably connected, the axis of the drive shaft and the axis of the driven shaft are parallel. When the mounting member and the connecting block of the second detection structure are detachably connected, the axis of the drive shaft and the axis of the driven shaft intersect.

[0007] A magnetic wheel torque testing device according to an embodiment of the present invention has at least the following technical effects: In the magnetic wheel torque testing device of this application, when it is necessary to test the torque of a parallel-drive magnetic wheel, the operator selects the first detection structure, connects the mounting part of the first detection structure to the connecting block of the second mounting structure, then installs the magnetic drive wheel on the drive shaft of the first mounting structure, and installs the magnetic driven wheel on the driven shaft of the first detection structure. At this time, the axes of the drive shaft and the driven shaft are parallel to simulate the meshing state of the magnetic wheel under parallel transmission conditions. The drive shaft is driven to rotate around its own axis by the driver. At this time, the sensor of the first detection structure can detect the torque of the parallel-drive magnetic wheel. The torque is detected by the sensor in the first detection structure. When testing the torque of the magnetic wheel in a right-angle drive, the operator selects the second detection structure, connects the mounting part of the second detection structure to the connecting block of the second mounting structure, and then installs the magnetic drive wheel on the drive shaft of the first mounting structure and the magnetic driven wheel on the driven shaft of the second detection structure. At this time, the axes of the drive shaft and the driven shaft intersect to simulate the meshing state of the magnetic wheel in a spatially intersecting shaft drive. The drive shaft is driven to rotate around its own axis by the driver. At this time, the sensor of the first detection structure can detect the torque of the magnetic wheel in the spatially intersecting shaft drive. As can be seen from the above, this application can test the torque of both parallel drive and spatially intersecting shaft drive magnetic wheels by providing two different specifications of detection structures, thereby improving the versatility of the testing equipment of this application.

[0008] According to a first aspect of the present invention, a magnetic wheel torque testing device includes a mounting component comprising a first mounting surface and a second mounting surface. The first mounting surface is detachably connected to a connecting block, and the second mounting surface is detachably connected to a sensor. In a first detection structure, the first mounting surface and the second mounting surface are arranged parallel to each other, and in a second detection structure, the first mounting surface and the second mounting surface are arranged at an angle to each other.

[0009] According to a first aspect of the present invention, a magnetic wheel torque testing device includes a driven shaft comprising a connecting section and a mounting section. The diameter of the connecting section is larger than the diameter of the mounting section. The connecting section is connected to the detection end of a sensor, and the mounting section is threadedly connected to the connecting section. The mounting section is used to pass through a magnetic driven wheel.

[0010] According to a first aspect of the present invention, a magnetic wheel torque testing device has an adjustable position of the detection structure relative to the base.

[0011] According to a first aspect of the present invention, a magnetic wheel torque testing device is provided on a base with a slide rail extending in a horizontal direction, and a second mounting structure is slidably mounted on the slide rail. Under the action of an external force, the second mounting structure can slide along the slide rail to drive the driven shaft to approach or move away from the driving shaft.

[0012] According to a first aspect of the present invention, a magnetic wheel torque testing device includes a second mounting structure that further includes a frame, on which a connecting block is disposed in an adjustable position along the vertical direction.

[0013] According to a first aspect of the present invention, a magnetic wheel torque testing device has a plurality of snap-fit ​​surfaces on the circumferential surface of the mounting section, and the plurality of snap-fit ​​surfaces are arranged circumferentially around the axis of the mounting section.

[0014] According to a second aspect embodiment of the present invention, a debugging method is applied to a magnetic wheel torque testing device as described in the first aspect embodiment above. The debugging method includes the following steps: The magnetic driven wheel is fitted onto the mounting section; Install the mounting section onto the connecting section using threads, and keep the mounting section in a loose state relative to the connecting section; Drive the driven magnetic wheel close to the driving magnetic wheel, so that the driven magnetic wheel drives the mounting section to rotate relative to the connecting section under the magnetic force of the driving magnetic wheel, and tightens the mounting section onto the connecting section.

[0015] A debugging method according to a second aspect of the present invention further includes the following steps: The driving magnetic wheel rotates, causing the driven magnetic wheel to rotate relative to the connecting section again under the magnetic force of the driving magnetic wheel, and further tightening the mounting section onto the connecting section.

[0016] According to a third aspect of the present invention, a data processing method is applied to a magnetic wheel torque testing device as described in the first aspect of the present invention. The data processing method includes the following steps: Acquire torque data detected in real time by the sensor; Set up a rectangular coordinate system with time as the horizontal axis and torque magnitude as the vertical axis; Plot the torque data over time in a Cartesian coordinate system; Based on the maximum and minimum torque data, the corresponding upper and lower reference values ​​are selected from the database in sequence. Adjust the maximum value of the ordinate in the rectangular coordinate system to the upper reference value, and adjust the minimum value of the ordinate in the rectangular coordinate system to the lower reference value.

[0024] The following is for reference. Figures 1 to 5 A magnetic wheel torque testing device according to a first aspect embodiment of the present invention will be described in detail.

[0025] refer to Figures 1 to 4 According to an embodiment of the present invention, a magnetic wheel torque testing device includes a base 100, a first mounting structure 200, a second mounting structure 300, and at least two detection structures 400. The first mounting structure 200 includes a first mounting bracket 210, a driver 220, and a drive shaft 230. The first mounting bracket 210 is disposed on the base 100, and the drive shaft 230 is rotatably disposed on the first mounting bracket 210. The driver 220 is connected to the drive shaft 230 and is used to drive the drive shaft 230 to rotate around its own axis. A magnetic drive wheel is disposed on the drive shaft 230. The second mounting structure 300 is disposed on the base 100 and has a connecting block 310. The detection structures 400 include a mounting member 410 and a sensor. The device 420 and driven shaft 430 are provided. The mounting part 410 is used for detachable connection with the connecting block 310. The sensor 420 is disposed on the mounting part 410. The detection end of the sensor 420 is connected to the driven shaft 430. The driven shaft 430 is used to pass through the magnetic driven wheel. Among them, at least two detection structures 400 include a first detection structure 400A and a second detection structure 400B with different specifications. When the mounting part 410 and the connecting block 310 of the first detection structure 400A are detachably connected, the axis of the drive shaft 230 and the axis of the driven shaft 430 are arranged parallel. When the mounting part 410 and the connecting block 310 of the second detection structure 400B are detachably connected, the axis of the drive shaft 230 and the axis of the driven shaft 430 are intersected.

[0026] In the magnetic wheel torque testing device of this application, when it is necessary to test the torque of the parallel transmission magnetic wheel, the operator selects the first detection structure 400A, connects the mounting part 410 of the first detection structure 400A to the connecting block 310 of the second mounting structure 300, and then installs the magnetic drive wheel on the drive shaft 230 of the first mounting structure 200 and the magnetic driven wheel on the driven shaft 430 of the first detection structure 400A. At this time, the axes of the drive shaft 230 and the driven shaft 430 are parallel to simulate the meshing state of the magnetic wheel under parallel transmission conditions. The drive shaft 230 is driven to rotate around its own axis by the driver 220. At this time, the sensor 420 of the first detection structure 400A can detect the torque of the parallel transmission magnetic wheel. The torque is detected. When it is necessary to test the torque of the magnetic wheel in orthogonal transmission, the operator selects the second detection structure 400B, connects the mounting part 410 of the second detection structure 400B to the connecting block 310 of the second mounting structure 300, and then installs the magnetic drive wheel on the drive shaft 230 of the first mounting structure 200 and the magnetic driven wheel on the driven shaft 430 of the second detection structure 400B. At this time, the axes of the drive shaft 230 and the driven shaft 430 intersect to simulate the meshing state of the magnetic wheel in the spatial intersecting shaft transmission condition. The drive shaft 230 is driven to rotate around its own axis by the driver 220. At this time, the sensor 420 of the first detection structure 400A can detect the torque of the magnetic wheel in the spatial intersecting shaft transmission. It can be seen from the above that by providing two different specifications of detection structures 400, this application can test the torque of both parallel transmission and spatial intersecting shaft transmission magnetic wheels, thereby improving the versatility of the testing equipment of this application.

[0027] Specifically, the axis of the drive shaft 230 is perpendicular to the axis of the driven shaft 430 of the second detection structure 400B. The driver 220 is a servo motor. The first mounting structure 200 is fixed to one end of the base 100, and its first mounting bracket 210 is used to support the drive shaft 230. The drive shaft 230 rotates smoothly through a high-precision bearing.

[0028] refer to Figures 1 to 4 In some embodiments of the present invention, the mounting component 410 includes a first mounting surface 410a and a second mounting surface 410b. The first mounting surface 410a is detachably connected to the connecting block 310, and the second mounting surface 410b is detachably connected to the sensor 420. In the first detection structure 400A, the first mounting surface 410a and the second mounting surface 410b are arranged parallel to each other. In the second detection structure 400B, the first mounting surface 410a and the second mounting surface 410b are arranged at a certain angle.

[0029] It is understood that when the sensor 420 is mounted on the second mounting surface 410b of the mounting member 410 of the first detection structure 400A, and the mounting member 410 of the first detection structure 400A is mounted on the connecting block 310, the drive shaft connected to the sensor 420 and the drive shaft 230 of the first mounting structure 200 are axially parallel. Conversely, when the sensor 420 is mounted on the second mounting surface 410b of the mounting member 410 of the second detection structure 400B, and the mounting member 410 of the second detection structure 400B is mounted on the connecting block 310, the drive shaft connected to the sensor 420 and the drive shaft 230 of the first mounting structure 200 intersect each other axially. This application allows for the testing of the torque of magnetic wheels with two different transmission methods by replacing the mounting member 410 with different structures. This greatly simplifies the operator's replacement operation, effectively avoids testing errors introduced by human adjustment mistakes, and ensures the reliability and repeatability of the test results.

[0030] Specifically, in the second detection structure 400B, the first mounting surface 410a of the mounting member 410 is perpendicular to the second mounting surface 410b.

[0031] refer to Figure 1 and Figure 5 In some embodiments of the present invention, the driven shaft 430 includes a connecting section 431 and a mounting section 432. The diameter of the connecting section 431 is larger than the diameter of the mounting section 432. The connecting section 431 is connected to the detection end of the sensor 420. The mounting section 432 is threadedly connected to the connecting section 431 and is used to mount the magnetic driven wheel. It is understood that the mounting section 432 is the part that directly mounts the magnetic driven wheel and is also the part that is most prone to wear or needs to be replaced according to the hub bore diameter. When it is necessary to test magnetic wheels with different bore diameters or when the mounting section 432 is worn, only the lower-cost mounting section 432 needs to be replaced, without replacing the entire driven shaft 430. This increases the versatility of the testing equipment of this application and reduces the maintenance and replacement costs of the testing equipment of this application. Furthermore, the robust connecting section 431 ensures the connection rigidity and concentricity with the sensor 420, while the narrow-diameter mounting section 432 adapts to the inner bore size of the magnetic wheel.

[0032] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the position of the detection structure 400 relative to the base 100 is adjustable. It is understood that by adjusting the position of the detection structure 400 relative to the base 100, the distance between the magnetic drive wheel on the drive shaft 230 and the magnetic driven wheel on the driven shaft 430 can be adjusted, thereby maintaining the gap between the magnetic driven wheel and the magnetic drive wheel at the optimal working gap, so that there is a sufficiently strong magnetic coupling between the magnetic driven wheel and the magnetic drive wheel, thereby generating effective torque.

[0033] Understandably, during the debugging process of the test equipment in this application, the magnetic drive wheel is first installed on the drive shaft 230, and the magnetic driven wheel is fixed on the mounting section 432 of the driven shaft 430. Then, the mounting section 432 is threaded onto the connecting section 431. At this time, the mounting section 432 remains loose relative to the connecting section 431. Then, the second mounting structure 300 is driven closer to the first mounting structure 200, so that the magnetic driven wheel approaches the magnetic drive wheel. During this process, the magnetic driven wheel can drive the mounting section 432 to rotate relative to the connecting section 431 under the magnetic force of the magnetic drive wheel. When the torque of the magnetic driven wheel reaches its maximum value, the frictional force between the mounting section 432 and the connecting section 431 is greater than or equal to the torque on the magnetic driven wheel. At this point, the mounting section 432 is stationary relative to the connecting section 431 and is tightened onto the connecting section 431. The magnetic driven wheel and the magnetic driving wheel reach a state of static equilibrium. The detection value of the sensor 420 at this time is set to zero. Then, the magnetic driving wheel is driven to rotate by the driver 220. The torque measured by the sensor 420 can more accurately reflect the transmission capability of magnetic coupling, rather than a mixed result containing other interfering forces.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, a horizontally extending slide rail 110 is provided on the base 100, and a second mounting structure 300 is slidably mounted on the slide rail 110. Under the action of external force, the second mounting structure 300 can slide along the slide rail 110 to drive the driven shaft 430 closer to or away from the drive shaft 230. It is understood that the transmission torque between the magnetic wheels is very sensitive to their axial distance. This application achieves the adjustment of the distance between the magnetic driven wheel on the driven shaft 430 and the magnetic drive wheel on the drive shaft 230 by sliding the second mounting structure 300 along the slide rail 110 to drive the detection structure 400 closer to or away from the first mounting structure 200. Researchers can systematically study the influence of the distance change between the magnetic wheels on the transmission torque. At the same time, by flexibly adjusting the distance between the drive shaft 230 and the driven shaft 430, the torque of magnetic wheels of various sizes and specifications can also be detected, further enhancing the versatility of the device in this application.

[0035] like Figure 1 and Figure 2As shown, in one embodiment, the magnetic wheel torque testing device further includes a locking structure 500, which is mounted on the second mounting structure 300 and used to fix the second mounting structure 300 to the slide rail 110. It is understood that during the torque test, there is a periodic magnetic force between the magnetic wheels, which may cause slight vibrations or displacements in the second mounting structure 300. By fixing the second mounting structure 300 to the slide rail 110 using the locking structure 500, the stability of the second mounting structure 300 during testing is ensured, effectively eliminating test data fluctuations or errors caused by the sliding of the second mounting structure 300, and guaranteeing the stability and accuracy of the test results.

[0036] Understandably, during the debugging process of the testing equipment of this application, the operator pushes the second mounting structure 300 along the slide rail 110 closer to the first mounting structure 200, so that the magnetic driven wheel is close to the magnetic driving wheel. When the distance between the magnetic driving wheel and the magnetic driven wheel is small, the pushing force applied to the second mounting structure 300 is removed. Under the magnetic force of the magnetic driving wheel, the magnetic driven wheel can drive the second mounting structure 300 to slide along the slide rail 110 to a position of static equilibrium. At this time, the second mounting structure 300 stops sliding, and then the locking structure 500 fixes the second mounting structure in this position to ensure the stability of the second mounting structure 300 during testing. Through the magnetic force between the magnetic driving wheel and the magnetic driven wheel, the magnetic driven wheel is automatically balanced without manual adjustment, reducing the possibility of measurement deviation caused by manual adjustment, thereby improving the accuracy of the testing equipment of this application.

[0037] Specifically, the locking structure 500 is a locking screw, which is threadedly connected to the second mounting structure 300. When the locking screw abuts against the base 100, the abutting force between the locking screw and the base 100 can prevent the second mounting structure 300 from sliding relative to the base 100, thereby fixing the second mounting structure 300.

[0038] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the second mounting structure 300 further includes a frame 320, on which the connecting block 310 is vertically adjustable. It is understood that by adjusting the height of the connecting block 310 on the frame 320, the vertical position of the driven shaft 430 can be adjusted, thereby adjusting the vertical distance between the magnetic driving wheel on the driving shaft 230 and the magnetic secondary driving wheel on the driven shaft 430. Therefore, the testing equipment of this application can be flexibly adjusted according to magnetic wheels of different sizes to ensure the relative distance between the magnetic driving wheel and the magnetic secondary driving wheel, further improving the versatility of this application.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the second mounting structure 300 further includes a screw 330, which extends vertically and is rotatably mounted on the frame 320. The screw 330 is threadedly connected to a connecting block 310, which is slidably mounted vertically on the frame 320. It is understood that the user can drive the screw 330 to rotate forward, thereby moving the connecting block 310 upward vertically; and drive the screw 330 to rotate in the opposite direction, thereby moving the connecting block 310 downward vertically. The screw 330 allows for precise adjustment of the vertical position of the connecting block 310, thus enabling precise adjustment of the vertical position of the driven shaft 430, and consequently, precise adjustment of the relative distance between the magnetic drive wheel and the magnetic driven wheel.

[0040] It should be noted that when testing some magnetic wheels with large torque, it is necessary to ensure that the mounting section 432 and the connecting section 431 bracket of the driven shaft 430 are connected tightly, so that the mounting section 432 is not easy to remove and replace from the connecting section 431.

[0041] like Figure 1 and Figure 5 As shown, in some embodiments, the mounting segment 432 has a plurality of snap-fit ​​surfaces 432a on its circumferential surface, and the plurality of snap-fit ​​surfaces 432a are circumferentially spaced around the axis of the mounting segment 432. It can be understood that by providing snap-fit ​​surfaces 432a on the circumferential surface of the mounting segment 432, the user can disassemble the mounting segment 432 by using a wrench to snap the snap-fit ​​surfaces 432a, thereby making it easier to remove the mounting segment 432 from the connecting segment 431.

[0042] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the magnetic wheel torque testing device further includes a display, which is electrically connected to the sensor 420 and is used to display the detection data of the sensor 420. It is understood that the display establishes an electrical connection with the sensor 420 via a signal cable. Real-time torque and other data detected by the sensor 420 are transmitted to the display via the cable. The display's built-in processing chip processes the data and displays it intuitively on the screen in the form of numbers, curves, or graphs. This makes reading the test data intuitive, convenient, and accurate. Operators can observe torque changes in real time without relying on additional data acquisition equipment or manual recording, greatly improving testing efficiency and data objectivity, and enhancing the intelligence level of the equipment and user experience.

[0043] The following is for reference. Figure 6 A debugging method according to a second aspect of the present invention will be described in detail.

[0044] refer to Figure 6 According to a second aspect of the present invention, a debugging method is applied to a magnetic wheel torque testing device as described in the first aspect of the present invention. The debugging method specifically includes, but is not limited to, the following steps: Step S110: Place the magnetic driven wheel onto the mounting section 432; Step S120: Thread the mounting section 432 onto the connecting section 431, and keep the mounting section 432 in a loose state relative to the connecting section 431; Step S130: Drive the driven magnetic wheel close to the driven magnetic wheel so that the driven magnetic wheel drives the mounting section 432 to rotate relative to the connecting section 431 under the magnetic force of the driven magnetic wheel, and tightens the mounting section 432 onto the connecting section 431.

[0045] Understandably, during the debugging process of the test equipment in this application, the magnetic drive wheel is first installed on the drive shaft 230, and the magnetic driven wheel is fixed on the mounting section 432 of the driven shaft 430. Then, the mounting section 432 is threaded onto the connecting section 431, and the mounting section 432 is kept loose relative to the connecting section 431. Next, the second mounting structure 300 is driven closer to the first mounting structure 200, so that the magnetic driven wheel approaches the magnetic drive wheel. During this process, the magnetic driven wheel can drive the mounting section 432 to rotate relative to the connecting section 431 under the magnetic force of the magnetic drive wheel, until the magnetic driven wheel... When the torque of the driven wheel reaches its maximum value, and the frictional force between the mounting section 432 and the connecting section 431 is greater than or equal to the torque on the magnetic driven wheel, the mounting section 432 remains stationary relative to the connecting section 431. At this point, the mounting section 432 is tightened onto the connecting section 431, and the magnetic driven wheel and the magnetic driving wheel reach a state of static equilibrium. The value detected by the sensor 420 at this time is set to zero. Then, the driver 220 drives the magnetic driving wheel to rotate. In this state, the torque measured by the sensor 420 can more accurately reflect the transmission capability of the magnetic coupling, rather than a mixed result containing other interfering forces. This application enables the magnetic driven wheel to automatically balance through the magnetic force between the magnetic driving wheel and the magnetic driven wheel, eliminating the need for manual adjustment and reducing the possibility of measurement deviation caused by manual adjustment.

[0046] In some embodiments, the step S130 of driving the driven magnetic wheel closer to the driven magnetic wheel specifically includes the following steps: pushing the second mounting structure 300 along the slide rail 110 closer to the first mounting structure 200, so that the driven magnetic wheel is close to the driven magnetic wheel; when the distance between the driven magnetic wheel and the driven magnetic wheel is small, the thrust applied to the second mounting structure 300 is removed; under the magnetic force of the driven magnetic wheel, the driven magnetic wheel can drive the second mounting structure 300 to slide along the slide rail 110 to a position of static equilibrium; at this time, the second mounting structure 300 stops sliding; and then the locking structure 500 fixes the second mounting structure in this position to ensure the stability of the second mounting structure 300 during testing.

[0047] like Figure 6 As shown, the debugging method also includes the following steps: Step S140: Drive the magnetic drive wheel to rotate so that the magnetic driven wheel, under the magnetic force of the magnetic drive wheel, drives the mounting section 432 to rotate again relative to the connecting section 431, and further tightens the mounting section 432 onto the connecting section 431.

[0048] Understandably, as the driven magnetic wheel approaches the driving magnetic wheel, and under the magnetic force of the driving magnetic wheel, the driven magnetic wheel rotates the mounting section 432 relative to the connecting section 431, and then remains stationary relative to the driving magnetic wheel, to further ensure that the torque between the driven and driving magnetic wheels reaches its maximum value, the driving magnetic wheel is driven to rotate. If the torque on the driven magnetic wheel has not yet reached its maximum value, the driven magnetic wheel, under the magnetic force of the driving magnetic wheel, will further drive the mounting section 432 to rotate again relative to the connecting section 431, thus ensuring that the mounting section 432 is tightened onto the connecting section 431. If the torque on the driven magnetic wheel has already reached its maximum value, even if the driving magnetic wheel rotates, the subsequent magnetic force on the driven magnetic wheel will not continue to increase, thus allowing the driven magnetic wheel to remain stationary. In summary, by driving the driving magnetic wheel to rotate, it is possible to detect whether the magnetic force on the driven magnetic wheel has reached its maximum, reducing the possibility that the driven magnetic wheel might rotate under the magnetic force of the driving magnetic wheel during subsequent testing, thereby affecting the accuracy of the test.

[0049] The following is for reference. Figure 7 A data processing method according to a third aspect of the present invention will be described in detail.

[0050] refer to Figure 7 According to a third aspect embodiment of the present invention, a data processing method is applied to the magnetic wheel torque testing device as described in the first aspect embodiment above. The data processing method specifically includes the following steps: Step S210: Obtain the torque data detected in real time by sensor 420; Step S220: Set up a rectangular coordinate system with time as the horizontal axis and torque magnitude as the vertical axis; Step S230: Plot the torque data over time in a rectangular coordinate system; Step S240: Select the corresponding upper and lower reference limits from the database according to the maximum and minimum torque data; Step S250: Adjust the maximum value of the ordinate in the rectangular coordinate system to the upper reference value, and adjust the minimum value of the ordinate in the rectangular coordinate system to the lower reference value.

[0051] Understandably, by using sensor 420 to detect the torque of the magnetic wheel in real time, and setting up a Cartesian coordinate system with time as the x-axis and torque magnitude as the y-axis, a curve of torque data changing over time is plotted in the Cartesian coordinate system and displayed intuitively on the screen. This facilitates observation of whether the magnetic force of the magnetic wheel is uniform. Furthermore, based on the maximum and minimum torque data, the corresponding upper and lower reference values ​​are selected from the database. Then, the maximum value of the y-axis in the Cartesian coordinate system is adjusted to the upper reference value, and the minimum value of the y-axis in the Cartesian coordinate system is adjusted to the lower reference value. This makes the curve changes in the graph more obvious, and the tested torque curve is easier to observe.

[0052] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
