Description

Technical Field

[0001] This application relates to the field of measurement equipment calibration technology, and in particular to a calibration device. Background Technology

[0002] The various gaps formed by the stator and rotor of the exciter have a significant impact on the exciter's performance. To improve the exciter's performance, these gaps need to be tested before manufacturing and use. The measuring equipment needs to measure not only the gaps of different exciter gaps of the same model but also the gaps of different exciter models. However, the measuring equipment inevitably has errors during use. To reduce the risk of excessive testing errors, the measuring equipment often needs to be calibrated. In existing technologies, to calibrate the measuring equipment, it needs to be placed directly on the exciter. This is problematic because exciter models are numerous, structures are complex, and gaps are small. The space available for the measuring equipment during testing is limited, making operation difficult, and the calibration process time-consuming and inefficient. Utility Model Content

[0046] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] The various gaps formed by the stator and rotor of the exciter have a significant impact on the exciter's performance. To improve the exciter's performance, these gaps need to be tested before manufacturing and use. The measuring equipment needs to measure not only the gaps of different exciter gaps of the same model but also the gaps of different exciter models. However, the measuring equipment inevitably has errors during use. To reduce the risk of excessive testing errors, the measuring equipment often needs to be calibrated. In existing technologies, to calibrate the measuring equipment, it needs to be placed directly on the exciter. This is problematic because exciter models are numerous, structures are complex, and gaps are small. The space available for the measuring equipment during testing is limited, making operation difficult, and the calibration process time-consuming and inefficient.

[0049] To solve the above technical problems, such as Figures 1 to 8 As shown, this application proposes a calibration device 100 for simulating the excitation gap of an exciter to calibrate a measuring device 200 for measuring the excitation gap. The calibration device 100 includes a first simulation component 110, a second simulation component 120, and a measuring component 130.

[0050] like Figure 1 , Figure 2 as well as Figure 4 As shown, the second simulation component 120 is connected to the first simulation component 110. The first simulation component 110 includes a base platform 111, and the second simulation component 120 includes a simulation element 123 spaced apart from the base platform 111. A calibration gap 121 is defined between the base platform 111 and the simulation element 123. The calibration gap 121 is used to simulate the excitation gap of the exciter. The specific shape and size of the second simulation component 120 can be simulated according to different models of exciters.

[0051] It is understood that the excitation gap of the exciter includes the gap between the magnetic poles of the stator and the gap between the stator and the rotor. In different gap simulations, the first simulation component 110 can be used to simulate the magnetic pole of one stator and the second simulation component 120 can be used to simulate the magnetic pole of another stator adjacent to the first simulation component 110, thereby simulating the gap between the magnetic poles of the two stators; or the first simulation component 110 can be used to simulate the rotor and the second simulation component 120 can be used to simulate the stator, thereby simulating the gap between the stator and the rotor; or other gap simulation methods can be used, which are not limited in this embodiment.

[0052] like Figure 2 as well as Figure 4As shown, both the measuring component 130 and the measuring device 200 can measure the value of the calibration gap 121. The measurement data from the measuring component 130 provides a calibration standard for the measuring device 200. In other words, the calibration device 100 simulates the excitation gap of the exciter, which is also the calibration gap 121. The measuring device 200 can measure the calibration gap 121. The calibration device 100 itself is equipped with a measuring component 130 for measuring the calibration gap 121. By comparing the value of the measuring device 200 with the value of the measuring component 130, the measuring device 200 can be calibrated based on the difference between the two. Specifically, if the difference between the two is within the allowable preset range, it means that the measuring device 200 can meet the measurement accuracy requirements, and the measuring device 200 does not need to be calibrated; if the difference between the two is greater than the allowable preset range, it means that the measuring device 200 has low measurement accuracy, and the measuring device 200 needs to be calibrated. Then, the calibrated measuring device 200 is calibrated by the calibration device 100 until the difference between the two is within the allowable preset range, that is, until the measuring device 200 can meet the measurement accuracy requirements, and the calibration operation can be ended.

[0053] The size of the calibration gap 121 detected by the measuring device 200 and the measuring component 130 can be the radial dimension, circumferential dimension, or other values ​​of the calibration gap 121.

[0054] In the technical solution of this application, the calibration device 100 includes a first simulation component 110, a second simulation component 120, and a measurement component 130. The measurement component 130 is used to measure the value of the calibration gap 121, so that the operator can compare the measurement data of the measurement component 130 with the measurement data of the measurement device 200. By using the measurement data of the measurement component 130 as a calibration standard, it is easier to determine whether the measurement error of the measurement device 200 is within the allowable preset range, that is, it is easier to determine whether the measurement accuracy of the measurement device 200 meets the measurement accuracy requirements.

[0055] The calibration device 100 of this application can simulate the excitation gap of an exciter, providing a simulated environment for the calibration of the measuring device 200, and the measurement data of the measuring component 130 can provide a calibration standard for the measuring device 200. Therefore, the calibration device 100 can simulate the excitation gap, thereby eliminating the need for the exciter to calibrate the measuring device 200, greatly reducing the time and location limitations of the calibration of the measuring device 200, and significantly improving the convenience of calibration of the measuring device 200.

[0056] Furthermore, it is understandable that the exciter has a complex structure and a small excitation gap, which makes the measuring device 200 difficult to operate during the measurement process. In order to improve the operator's proficiency in using the measuring device 200 and improve measurement efficiency, the calibration device 100 can also be used to train operators to improve their proficiency in using the measuring device 200 and thus improve measurement efficiency.

[0057] In some implementations, please refer to Figure 1 , Figure 2 The first simulation component 110 also includes a first support component 112 and a second support component 113. The first support component 112 and the second support component 113 are both vertically arranged on the base platform 111, and the first support component 112 and the second support component 113 are arranged at intervals relative to each other. The second support component 113 is used to install the measuring device 200. The simulation component 123 is installed on the first support component 112, and the measuring component 130 is installed on the base platform 111 or the first support component 112. Thus, the first support component 112 provides an installation base for the simulation component 123 and the measuring component 130, and the second support component 113 provides an installation base for the measuring device 200 and the measuring component 130, so that the simulation component 123, the measuring component 130 and the measuring device 200 remain in a stable position during the measurement process. The measuring component 130 and the measuring device 200 are respectively installed on the first support component 112 and the second support component 113, and can measure the calibration gap 121. After the measurement is completed, the measurement data of the measuring component 130 can provide a calibration standard for the measuring device 200.

[0058] In some implementations, please refer to Figure 1 , Figure 2 The second simulation component 120 can move relative to the first simulation component 110 to adjust the size of the calibration gap 121. Thus, by moving the second simulation component 120 relative to the first simulation component 110 to adjust the size of the calibration gap 121, the calibration device 100 can simulate the excitation gaps of different models of exciters or the excitation gaps at different locations. Furthermore, the calibration device 100 can calibrate the measuring device 200 when measuring excitation gaps of different sizes, effectively improving the performance and versatility of the measuring device.

[0059] like Figure 4 As shown, the second simulation component 120 can be configured according to different adjustment requirements. Specifically, the second simulation component 120 can move entirely relative to the first simulation component 110, or only a portion of its structure can move relative to the first simulation component 110.

[0060] Furthermore, in different embodiments, the method by which the measuring component 130 measures the calibration gap 121 may vary. Specifically, the size of the excitation gap can be obtained by directly measuring the distance between the simulation component 123 and the first simulation component 110; or the size of the excitation gap can be indirectly measured by measuring the displacement of the second simulation component 120. This embodiment does not limit this method.

[0061] In this embodiment, the second simulation component 120 further includes a drive structure 122, which is fixedly connected to the first support component 112. The simulation element 123 is connected to the drive structure 122. The drive structure 122 is used to drive the simulation element 123 to move closer to or further away from the base platform 111 to adjust the size of the calibration gap 121. For ease of description, the arrangement direction of the base platform 111 and the simulation element 123 is referred to as the first direction X.

[0062] Specifically, in the initial state, the simulation component 123 can abut against the base platform 111. The drive structure 122 drives the simulation component 123 to move away from the base platform 111, thereby separating the simulation component 123 from the base platform 111. The measuring component 130 can measure the size of the gap by detecting the displacement of the simulation component 123. The cooperation between the drive structure 122 and the simulation component 123 makes it easier to control the size of the calibration gap 121, allowing the calibration device 100 to easily and quickly set the size of the calibration gap according to calibration requirements. The detection value of the measuring component 130 serves as the reference value for the measuring device 200. The measuring component 130 can accurately measure the size of the excitation gap by detecting the translation of the simulation component 123. The high accuracy of the measuring component 130 leads to more accurate calibration of the measuring device 200.

[0063] Of course, in other possible implementations, the second simulation component 120 may be hinged to the first simulation component 110, and the size of the calibration gap 121 may be adjusted by rotating the second simulation component 120 relative to the first simulation component 110. Alternatively, the second simulation component 120 may be slidably connected to the first simulation component 110, and the size of the calibration gap 121 may be adjusted by sliding the second simulation component 120 relative to the first simulation component 110. This embodiment does not impose any limitations on this.

[0064] It should be noted that, depending on different fixing requirements, the second simulation component 120 may also be equipped with fixing bolts. After the driving structure 122 drives the simulation component 123 to move to the preset position to form a calibration gap 121 of the preset size, the simulation component 123 can be fixed by fixing bolts to make the simulation component 123 stable in the preset position. This can effectively reduce the risk of the simulation component 123 moving unexpectedly during the calibration process and effectively ensure the reliability of the calibration.

[0065] To drive the simulation component 123 to translate along the first direction X, the drive structure 122 can be configured as any suitable device capable of driving the simulation component 123 to translate, as long as the drive structure 122 can meet the stroke control requirements of the simulation component 123.

[0066] In this embodiment, the second simulation component 120 includes a driving structure 122, a first connecting structure 1223, and a second connecting structure 1224. The first connecting structure 1223 is connected to the first support component 112, and the second connecting structure 1224 is connected to the simulation component 123 and slidably connected to the first connecting structure 1223. The second connecting structure 1224 is configured to slide relative to the first connecting structure 1223 towards or away from the base platform 111. The driving structure 122 is connected to the second connecting structure 1224 and is used to drive the second connecting structure 1224 to slide relative to the first connecting structure 1223. Thus, by driving the second connecting structure 1224 to slide relative to the first connecting structure 1223 through the driving structure 122, the second connecting structure 1224 can be moved closer to or away from the base platform 111, thereby causing the simulation component 123 to move synchronously closer to or away from the base platform 111, thereby changing the size of the calibration gap 121.

[0067] like Figure 3 As shown, in this embodiment, the drive structure 122 includes a rotary drive member 1221, a rotating member 1222, and a transmission screw 124. The rotary drive member 1221 is rotatably connected to the second connecting structure 1224. The transmission screw 124 is threadedly connected to the rotary drive member 1221 and can move along its extension direction (i.e., the second direction Y shown in the figure) under the drive of the rotary drive member 1221. The rotating member 1222 is rotatably mounted on the second connecting structure 1224 and is rotatably connected to the end of the transmission screw 124 and the first connecting structure 1223. The rotation axis of the rotating member 1222, the extension direction of the transmission screw 124, and the first direction X are arranged to intersect each other.

[0068] Based on this, by driving the rotary drive component 1221 to rotate, the transmission screw 124 moves along its extension direction (i.e., the second direction Y shown in the figure). This, in turn, drives the rotating component 1222 to rotate via the transmission screw 124, which in turn links the first connecting structure 1223, causing relative sliding between the first connecting structure 1223 and the second connecting structure 1224. This allows the second connecting structure 1224 to move closer to or further away from the base platform 111, thereby causing the simulation component 123 to move synchronously closer to or further away from the base platform 111, thus changing the size of the calibration gap 121. In this way, through the cooperation of the rotary drive component 1221, the transmission screw 124, and the rotating component 1222, rotational motion can be converted into linear motion, making the relative sliding control between the first connecting structure 1223 and the second connecting structure 1224 more convenient, precise, and reliable.

[0069] Furthermore, a scale can be set on the rotary drive component 1221 to directly obtain the displacement value of the corresponding simulation component 123, thereby improving the convenience of reading the displacement of the simulation component 123. The scale reading can also be used to initially set the displacement of the simulation component 123 or to perform initial calibration of the measuring device 200.

[0070] Specifically, please refer to Figure 3 In this embodiment, the first connecting structure 1223 has a first connecting portion 12231 extending along the first direction X, the second connecting structure 1224 defines a first through hole 12241 extending along the second direction Y, the transmission screw 124 passes through the first through hole 12241, the rotating member 1222 has a second end 12221 and a third end 12222, the rotating member 1222 is rotatably connected to the second connecting structure 1224, the second end 12221 is rotatably connected to the first connecting portion 12231, and the third end 12222 is rotatably connected to the transmission screw 124.

[0071] In this embodiment, please refer to Figure 3 One of the first connecting structure 1223 and the second end 12221 of the rotating member 1222 has a first rotating ball portion, and the other has a first rotating groove for the first rotating ball portion to be adapted and rotatably mounted therein. One of the ends of the transmission screw 124 and the third end 12222 of the rotating member 1222 has a second rotating ball portion, and the other has a second rotating groove for the second rotating ball portion to be adapted and rotatably mounted therein. Thus, the displacement control accuracy of the second connecting structure 1224 is improved through point contact between the rotating member 1222, the rotary drive member 1221, and the first connecting structure 1223.

[0072] Of course, in other possible implementations, the drive structure 122 can also be configured as a screw lifting platform or a linear motor, as long as the drive structure can drive the simulation component to move back and forth along the first direction. This embodiment does not limit this.

[0073] For example, the drive structure 122 can be configured as a lead screw lifting platform. The lead screw lifting platform includes a lead screw extending along a first direction X, and a nut threaded to the lead screw. The lead screw is rotatably connected to a first support assembly 112, and the nut is connected to a simulation element 123. Thus, by rotating the lead screw, the nut can be driven to move along the lead screw, i.e., the first direction X, and the simulation element 123 can be indirectly driven to move along the first direction X through the nut, thereby achieving the purpose of adjusting the calibration gap 121.

[0074] Furthermore, by using the cooperation between the lead screw and the nut to convert the rotation of the lead screw into the translational motion of the nut, the lead screw lifting platform has high precision control, which can effectively improve the control precision of the simulation component 123.

[0075] It is understood that in other possible implementations, the measurement component 130 may not need to be set up separately, and the displacement of the simulation component 123 may be obtained directly through the drive structure 122. In this case, it can be understood that the measurement component 130 and the second simulation component 120 are integrated into a single design.

[0076] For example, the drive structure 122 can be configured as a linear motor. Linear motors do not require an intermediate conversion mechanism to convert rotary motion into linear motion. They are simple in structure, lightweight, small in size, have low inertia, fast response speed, high sensitivity, and high dynamic response performance and positioning accuracy. Linear motors employ advanced technologies such as grating closed-loop control, enabling nanometer-level control to meet the high-precision positioning requirements of the analog component 123. Linear motors transmit power without contact, resulting in almost zero mechanical friction loss, low failure rate, safety, reliability, and long service life, facilitating repeated calibration and practice of the measuring equipment 200.

[0077] The measuring component 130 can be configured according to different usage requirements. Specifically, the measuring unit 134 can be configured as a dial indicator 131. For example... Figure 4 As shown, in this embodiment, the dial indicator 131 includes a fixing part 132, a display part 133, and a measuring part 134. The fixing part 132 is fixedly connected to the first support assembly 112. The measuring part 134 is connected to the fixing part 132 and abuts against the side of the simulation component 123 away from the base platform 111. The display part 133 is used to display the displacement of the measuring part 134.

[0078] To meet the connection requirements between the first analog component 110 and the dial indicator 131, in some embodiments, the fixing part 132 is configured as a bolt. The first analog component 110 may have a through hole and a threaded hole communicating with the through hole. The through hole is used to pass through the measuring part 134, i.e., the measuring rod, and the threaded hole is used to pass through the bolt, so that the bolt and the measuring rod abut against and fix the dial indicator 131. The dial indicator 131 can amplify the minute linear movement of the measuring rod caused by the movement of the analog component 123 through gear transmission, and convert it into the rotation of the pointer on the dial, thereby reading the size of the measured dimension. Even a very small displacement can be accurately captured by the measuring rod and converted into the rotation of the pointer, so the dial indicator 131 has extremely high sensitivity. On the one hand, the dial indicator 131 can intuitively display displacement data; on the other hand, the dial indicator 131 can also be connected to devices such as computers, effectively avoiding manual reading errors, improving measurement efficiency and accuracy, and facilitating data storage and analysis.

[0079] In some embodiments, the first simulation component 110 is used to simulate the rotor, and the second simulation component 120 is used to simulate the stator. To improve the simulation accuracy of the exciter, the first simulation component 110 may have a bottom surface 1112, and may also have a wall surface intersecting the bottom surface 1112, so as to realize the simulation of the wall surface of the rotor near the stator. Figure 4 As shown, in this embodiment, the side of the simulation component 123 closest to the base platform 111 is the first side surface 1232, the side of the base platform 111 that defines the calibration gap 121 with the simulation component 123 is the second side surface 1111, the side of the base platform 111 facing away from the simulation component 123 is the bottom surface 1112, the second side surface 1111 is parallel to the first side surface 1232, and the second side surface 1111 and the first side surface 1232 together define the calibration gap 121. The angle α between the second side surface 1111 and the bottom surface 1112 satisfies: α ≤ 30°. Specifically, depending on the model of the simulated exciter, the angle α can be any suitable degree such as 30°, 20°, or 7.2°.

[0080] Understandably, the bottom surface 1112 is used to place the calibration device 100, and the second side surface 1111 is used to simulate the wall of the rotor near the stator, with the first direction X perpendicular to the second side surface 1111. The arrangement of the second side surface 1111 allows the calibration device 100 to more comprehensively simulate the excitation gap, further improving the reliability of the measuring device 200.

[0081] The base platform 111 includes a first base body 1116 and a second base body 1117 connected in sequence. The first base body 1116 and the second base body 1117 are flush with each other on the side away from the simulation component 123 and together form the bottom surface 1112. The side of the first base body 1116 closest to the simulation component 123 is the second side surface 1111, which forms a calibration gap 121 with the simulation component 123. The side of the second base body 1117 closest to the simulation component 123 is the third side surface 1113, which is parallel to the bottom surface 1112. The second side surface 1111 and the third side surface 1113 intersect at an obtuse angle. The second side surface 1111 and the third side surface 1113 together simulate the circumferential arc surface of the exciter rotor. Setting the angle between the second side surface 1111 and the third side surface 1113 to an obtuse angle allows the junction of the second side surface 1111 and the third side surface 1113 to better conform to the curvature of the rotor circumference.

[0082] The first support assembly 112 includes a first support structure vertically disposed on the first base 1116, and a first top plate 1125 connected to one end of the first support structure away from the first base 1116. The first top plate 1125 is connected to the simulation component 123. The side of the simulation component 123 near the first base 1116 is the first side surface 1232. The first side surface 1232 is parallel to the second side surface 1111 and defines a calibration gap 121. The second support assembly 113 includes a second support structure vertically disposed on the second base 1117, and a second top plate 1134 connected to one end of the second support structure away from the second base 1117. The second top plate 1133 is parallel to the third side surface 1113 and is used to mount the measuring device 200.

[0083] Thus, the measuring component 130 is located on one side of the calibration gap 121 along the first direction X, and the measuring device 200 is located on one side of the calibration gap 121 along the second direction Y. The measurement of the calibration gap 121 by the measuring component 130 and the measurement of the calibration gap 121 by the measuring device 200 do not affect each other. The two can measure the calibration gap 121 simultaneously, resulting in high measurement efficiency.

[0084] The connection stability between the second analog component 120 and the measurement component 130 and the first analog component 110 will affect the calibration accuracy of the calibration device 100. In order to improve the connection stability between the first analog component 110 and the second analog component 120 and the measurement component 130, a first support component 112 that cooperates with the base platform 111 can be set to provide a more stable foundation for the installation of the second analog component 120 and the measurement component 130.

[0085] like Figure 2 as well as Figure 4As shown, in this embodiment, the first support component 112 is connected to the base platform 111. The first top plate 1125 of the first support component 112 has a fourth side surface 1121, which, together with the second side surface 1111, defines a mounting cavity 1122. The second simulation component 120 is connected to the fourth side surface 1121 so that at least a portion of the second simulation component 120 is disposed in the mounting cavity 1122. Furthermore, the measuring component 130 may also be connected to the first support component 112, without limitation. The arrangement of the first support component 112 improves the stability of the second simulation component 120 and the measuring component 130, and also enhances the structural compactness of the calibration device 100, thereby reducing the cost of the calibration device 100 and improving its ease of use.

[0086] The first support assembly 112 can be configured according to different usage requirements. The first support assembly 112 can be composed of multiple plates connected by bolts, welded together from multiple plates, or integrally formed from multiple plates. For example... Figure 2 as well as Figure 6 As shown, in this embodiment, the first support structure includes a first upright plate 1123, a second upright plate 1124, and a first top plate 1125 for defining the mounting cavity 1122. The first upright plate 1123 and the second upright plate 1124 are both vertically disposed on the first base 1116 and spaced apart from each other. The ends of the first upright plate 1123 and the second upright plate 1124 away from the first base 1116 are both connected to the first top plate 1125. The first top plate 1125 and the base platform 111 are aligned along the first direction X. In this configuration, the first upright plate 1123 and the second upright plate 1124 are positioned opposite each other along a second direction Y, which intersects with the first direction X. Along the first direction X, one side of the first upright plate 1123 is connected to the base platform 111, and the other side is connected to the first top plate 1125. One side of the second upright plate 1124 is connected to the base platform 111, and the other side is connected to the first top plate 1125. The first top plate 1125 has a fourth side surface 1121 on the side closest to the base platform 111, which is parallel to the second side surface 1111. The first upright plate 1123, the second upright plate 1124, and the first top plate 1125 cooperate to provide installation space for the drive structure 122 and the simulation component 123, and to provide reliable protection for the simulation component 123 and the drive structure 122 to prevent damage to them due to accidental contact during the calibration process.

[0087] In other words, the first top plate 1125 is used to connect the second simulation component 120, and the first top plate 1125 can also be used to set the measuring component 130. The first upright plate 1123 and the second upright plate 1124 provide stable support for the first top plate 1125, thereby making the first simulation component 110 more stable. It should be noted that the second side surface 1111 intersects with the bottom surface 1112, and the base platform 111 can have a plane parallel to the bottom surface 1112 that abuts against the first upright plate 1123 and the second upright plate 1124. In order to make the fourth side surface 1121 parallel to the second side surface 1111, the projections of the first upright plate 1123 and the second upright plate 1124 along the second direction Y on the projection plane perpendicular to the second direction Y can be right trapezoids. One side of the waist of the hypotenuse of the right trapezoid of the first upright plate 1123 and the second upright plate 1124 abuts against the first upright plate 1123, thereby making the fourth side surface 1121 parallel to the second side surface 1111. The parallel arrangement of the fourth side 1121 to the second side 1111 further improves the installation accuracy of the second simulation component 120. It should be noted that, to facilitate the installation of the second simulation component 120, the first upright plate 1123 or the second upright plate 1124 may also be provided with a clearance groove for the second simulation component 120, which is not limited here.

[0088] The exciter has a complex structure, making it difficult to directly place the detection end of the measuring device 200 into the excitation gap. When measuring the exciter, the exciter housing can be disassembled first, and then the measuring device 200 can be placed in the exciter gap. Alternatively, the detection head of the measuring device 200 can be inserted into the excitation gap through the measuring hole in the exciter housing to detect the excitation gap.

[0089] like Figure 2 as well as Figure 4 As shown, in this embodiment, the second top plate 1134 of the second support component 113 has a mounting hole 1135 that runs through the vertical direction (i.e., the third direction Z in the figure). The mounting hole 1135 communicates with the calibration gap 123. The mounting hole 1135 is a simulation of the measuring hole of the exciter housing. The mounting hole 1135 is used to install the measuring device 200.

[0090] The second support assembly 113 also includes a detection channel 1131. The mounting hole 1135 communicates with the calibration gap 123 through the detection channel 1131. The detection channel 1131 is suitable for the measuring device 200 to pass through, enabling the measuring device 200 to detect the calibration gap 121. In other words, the second support assembly 113 can simulate the channel connecting the exciter and the required excitation gap, thus providing a more accurate simulation environment for the measuring device 200 and improving the effectiveness of its operation and training. It should be noted that when the required excitation gap is the gap between the two magnetic poles of the stator, the detection channel 1131 defined by the second support assembly 113 is the gap between the two magnetic poles of the exciter. When the required excitation gap is the gap between the stator and the rotor, the detection channel 1131 is the gap between the stator and the rotor. The second support assembly 113 also provides support for the measuring device 200, improving the convenience of calibration.

[0091] like Figure 2 as well as Figure 7 As shown, in some embodiments, the base platform 111 further has a bottom surface 1112 and a third side surface 1113, the third side surface 1113 being parallel to the bottom surface 1112 and the third direction Z being perpendicular to the third side surface 1113. The second support assembly 113 includes a third upright plate 1132, a fourth upright plate 1133, and a second top plate 1134 for defining the detection channel 1131. The second top plate 1134 is arranged opposite to the base platform 111 along the third direction Z, and the third upright plate 1132 and the fourth upright plate 1133 are arranged along the second direction Y. The third and fourth upright plates are respectively positioned opposite each other and vertically mounted on the second base 1117. The second direction Y intersects the first direction X. The ends of the third upright plate 1132 and the fourth upright plate 1134, both located away from the second base 1117, are connected to the second top plate 1134. Along the third direction Z, one side of the third upright plate 1132 is connected to the base platform 111, and the other side is connected to the second top plate 1134. Similarly, one side of the fourth upright plate 1133 is connected to the base platform 111, and the other side is connected to the second top plate 1134.

[0092] The height and shape of the third upright plate 1132 and the fourth upright plate 1133 along the third direction Z can be set according to different simulation requirements. Specifically, the contact area between the third upright plate 1132 and the fourth upright plate 1133 and the second top plate 1134 can be larger than the contact area between the third upright plate 1132 and the fourth upright plate 1133 and the second top plate 1134, thereby improving the connection stability between the third upright plate 1132 and the fourth upright plate 1133 and the second top plate 1134.

[0093] The mounting hole 1135 vertically penetrates the second top plate 1134. The third vertical plate 1132, the fourth vertical plate 1133, and the second top plate 1134 together define the detection channel 1131. The mounting hole 1135 communicates with the calibration gap 123 through the detection channel 1131. The measuring device 200 passes through the mounting hole 1135 into the detection channel 1131 and measures the calibration gap 123. The third vertical plate 1132, the fourth vertical plate 1133, and the second top plate 1134 provide mounting space for the measuring device 200 and provide reliable protection for the measuring device 200. Figure 8 As shown, to further improve the stability of the second support assembly 113, the second support assembly 113 may also be provided with a reinforcing plate 1136. One side of the reinforcing plate 1136 is connected to the third upright plate 1132, and the other side is connected to the fourth upright plate 1133. The reinforcing plate 1136 can reduce the risk of swaying when the second support assembly 113 supports the measuring device 200. Furthermore, to improve the stability of the second support assembly 113, the thickness of the third upright plate 1132 and the fourth upright plate 1133 along the second direction Y can be not less than 12mm. Specifically, the thickness of the third upright plate 1132 and the fourth upright plate 1133 can be 12mm, 13mm, 15mm, or 15.5mm, etc., respectively, without limitation. Similarly, the thickness of the first upright plate 1123 and the second upright plate 1124 can also be not less than 12mm. The thickness of the first upright plate 1123 and the second upright plate 1124 can be the same as or different from that of the third upright plate 1132 and the fourth upright plate 1133, without limitation.

[0094] like Figure 5 As shown, to improve the accuracy and convenience of installing the calibration device 100, the base platform 111 may also be provided with a limiting groove, which is used to pre-position the first support component 112 and the second support component 113 for installation. In some embodiments, the first simulation component 110 includes the base platform 111 and the first support component 112. The first support component 112 and the base platform 111 together define a mounting cavity 1122 for setting the second simulation component 120. The base platform 111 is also provided with a first limiting groove 1114, and the first support component 112 is disposed in the first limiting groove 1114.

[0095] In some embodiments, the first simulation component 110 includes a base platform 111 and a second support component 113. The second support component 113 and the base platform 111 together define a detection channel 1131 for the measuring device 200 to pass through. The detection channel 1131 communicates with the calibration gap 121. The base platform 111 is also provided with a second limiting groove 1115, and the second support component 113 is disposed in the second limiting groove 1115. It should be noted that the first limiting groove 1114 can communicate with the second limiting groove 1115, and the first limiting groove 1114 and the second limiting groove 1115 can be configured as different segments of the same empty groove, thereby making the processing of the base platform 111 more convenient.

[0096] Specifically, along the second direction Y, the shortest distance between the first upright plate 1123 and the second upright plate 1124 can be equal to the shortest distance between the third upright plate 1132 and the fourth upright plate 1133. Along the second direction Y, both sides of the base platform 111 can be provided with a first limiting groove 1114 and a second limiting groove 1115, so that the first upright plate 1123, the second upright plate 1124, the third upright plate 1132, and the fourth upright plate 1133 can all be pre-positioned on the base platform 111 through the limiting grooves. During installation, the first support assembly 112 and the second support assembly 113 can be pre-positioned in the first limiting groove 1114 and the second limiting groove 1115 respectively. The first support assembly 112 and the second support assembly 113 are then pre-positioned on the base platform 111 using pins, and finally, bolts are used to fix the first support assembly 112 and the second support assembly 113 to the base platform 111. It is understood that the first support component 112 and the second support component 113 can also be connected to the base platform 111 by any suitable method such as welding. In addition, to further improve the installation accuracy of the calibration equipment 100, the calibration equipment 100 can be assembled and its quality inspected by a coordinate measuring machine, which will not be elaborated here.

[0097] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
