Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 . A calibration device for calibrating a torque limiter 20 includes:

[0058] A connection structure 10, including a first structure 11 and a second structure 12. The first structure 11 is used to connect the driving flange 21 of the torque limiter 20, and the second structure 12 is used to connect the driven flange 22 of the torque limiter 20;

[0059] The measuring structure 30 is disposed on the first structure 11 and / or the second structure 12, and is used to measure the measurement calibration data corresponding to the torque limiter 20; the measurement calibration data includes torque calibration data and displacement calibration data;

[0060] The loading structure 40 is disposed on the second structure 12 and is used to provide a thrust to the driving flange 21 through the first structure 11;

[0061] The control structure 60 is electrically connected to the measuring structure 30 and is used to receive and process the measurement calibration data to obtain the target calibration data.

[0062] The torque limiter 20 is a mechanical safety protection device, mainly used in systems for transmitting power, such as motors, speed reducers, transmission shafts, etc. The torque limiter 20 can cut off the power transmission during overload, thereby preventing mechanical components from being damaged due to overloading. The torque limiter 20 may include a driving end connected to the power source, i.e., the driving flange 21, and a driven end connected to the load end, i.e., the driven flange 22, and its working principle is as follows:

[0063] Under normal working conditions, when the system torque is lower than the set threshold, the driving flange 21 and the driven flange 22 of the torque limiter 20 are rigidly connected through a mechanical structure, and the torque can be transmitted normally. When the system torque exceeds the set threshold, the protection mechanism is triggered, and the internal mechanical structure disengages, causing relative sliding or physical separation between the driving flange 21 and the driven flange 22, and the power transmission path is cut off. In addition, after the overload is eliminated, some torque limiters 20, such as the thimble 23 type torque limiter 20, can be automatically reset to re - establish the power connection.

[0064] The calibration device in the present invention can be applied to the calibration of torque limiters 20 of different categories and different sizes, especially to the calibration process of non - standard products with large torque and large diameter. In the present invention, the thimble 23 type torque limiter 20 is taken as an example for illustration, that is, the torque limiter 20 in the present invention includes a driving flange 21, a driven flange 22 and a thimble 23, and the mechanical connection and power transmission between the driving flange 21 and the driven flange 22 are realized through the thimble 23.

[0065] In a specific embodiment, the calibration device may include a connection structure 10 for connecting and fixing the torque limiter 20, a measuring structure 30 for measuring the calibration data during the calibration of the torque limiter 20, a loading structure 40 for providing a thrust or torque to the torque limiter 20, and a control structure 60 for processing the measurement calibration data and generating the target calibration data.

[0066] Specifically, during the calibration process, the calibration device is connected to the test bench through the second structure 12, and the driven flange 22 of the torque limiter 20 is connected to the second structure 12 to fix the position of the torque limiter 20 on the test bench during the calibration process. The driving flange 21 and the driven flange 22 are mechanically connected through the ejector pin 23. The loading structure 40 provides a thrust to the driving flange 21 to make the driving flange 21 rotate, and the driving flange 21 drives the first structure 11 to move, so as to measure the displacement calibration data through the measuring structure 30. In addition, by setting the measuring structure 30 to be slightly in contact with the loading structure 40, the torque calibration data can be measured. Combining with the control structure 60, the calibration result corresponding to the torque limiter 20, that is, the target calibration data, can be obtained.

[0067] Please refer to Figures 1 to 4 As shown arbitrarily, in the connecting structure 10, the first structure 11 includes a connected first connecting portion 14 and a second connecting portion 15. The first connecting portion 14 and the second connecting portion 15 are distributed along the stacking direction of the driving flange 21 and the driven flange 22, and the first connecting portion 14 is used to connect the driving flange 21.

[0068] The first structure 11 includes a connecting hole 13. The ejector pin 23 of the torque limiter 20 is arranged on the driving flange 21, and the first connecting portion 14 is connected to the ejector pin 23. Specifically, the ejector pin 23 passes through the connecting hole 13 to connect the first structure 11 to the driving flange 21 of the torque limiter 20.

[0069] In a specific embodiment, the driving flange 21 is connected to the first structure 11 to enable the first structure 11 to rotate synchronously with the driving flange 21 during the calibration process. Specifically, a plurality of connecting holes 13 are provided on the first connecting portion 14, and the ejector pins 23 are inserted into the connecting holes 13 to realize the connection between the first structure 11 and the driving flange 21 of the torque limiter 20, so that the first structure 11 can rotate synchronously with the driving flange 21. In addition, the driving flange 21 can also be further fixedly connected to the first structure 11 through a bolt structure to improve the connection stability between the two.

[0070] The second structure 12 is fixed to the fixing member 50 and fixedly connected to the driven flange 22 of the torque limiter 20. The second structure 12 is located on one side of the driven flange 22 close to the fixing member 50, or the second structure 12 is located on one side of the driven flange 22 away from the fixing member 50.

[0071] In a specific embodiment, the second structure 12 is fixed to the fixing member 50, and the fixing member 50 can be any structure capable of fixing the second structure 12 to positions such as an operating table, a calibration test bench, etc., such as a fixing plate. The second structure 12 is fixedly connected to the driven flange 22 of the torque limiter 20, for example, fixedly connected through a bolt structure, so as to fix the torque limiter 20 to the fixing member 50 during the calibration process. For the connection manner between the second structure 12 and the driven flange 22, the driven flange 22 can be placed between the fixing member 50 and the second structure 12, or the second structure 12 can be placed between the fixing member 50 and the driven flange 22. In the embodiment of the present invention, the driven flange 22 can be placed between the fixing member 50 and the second structure 12. Since a part of the second structure 12 is connected to the driven flange 22, this connection manner can make the driven flange 22 lie in a plane, avoiding excessive power during overload from affecting the placement stability of the torque limiter 20 and improving the safety of the torque limiter 20 during the calibration process.

[0072] Please continue to refer to Figures 1 to 4 , the loading structure 40 is fixed to the second structure 12 through the connecting member 41. Specifically, a gap is formed between the second structure 12 and the second connecting portion 15. The loading structure 40 is fixedly connected to the second structure 12 through the connecting member 41 and is arranged between the gap between the second structure 12 and the second connecting portion 15, that is, the loading structure 40 is fixed to the second structure 12 and is arranged toward the first structure 11, so that the loading structure 40 provides a thrust for the driving flange 21 through the first structure 11. The connecting member 41 can be any structure capable of fixedly connecting the loading structure 40 and the second structure 12, such as a base matching the outer contour of the loading structure 40, or an adhesive layer capable of bonding the second structure 12 and the loading structure 40, etc.

[0073] In a specific embodiment, the loading structure 40 can be a double-acting hydraulic cylinder, and the direction of the provided thrust is parallel to the tangential direction of the driving flange 21. The magnitude of the loading torque applied to the torque limiter 20 can be adjusted by adjusting the magnitude of the loading force of the hydraulic cylinder, thereby improving the flexibility of the calibration device for calibrating the torque limiter 20.

[0074] Please continue to refer to Figures 1 to 4 , the measuring structure 30 includes a first sensor 31 and a second sensor 32 respectively electrically connected to the control structure 60;

[0075] Among them, the first sensor 31 is fixed to the first structure 11 and is used for measuring torque calibration data. The loading structure 40 pushes against the first sensor 31 to provide a thrust to the driving flange 21, so that relative movement occurs between the driving flange 21 and the driven flange 22. Specifically, the first sensor 31 is arranged on the side of the second connecting portion 15 facing the loading structure 40.

[0076] In a specific embodiment, the first sensor 31 may be a load cell and may be disposed on the side of the second connecting portion 15 facing the loading structure 40. There may be a gap between the first sensor 31 and the loading structure 40. When the loading structure 40 operates, a part of the loading structure 40 moves and pushes against the first sensor 31, so that the thrust provided by the first sensor 31 can be transmitted to the driving flange 21 through the first structure 11, and the driving flange 21 moves under the action of the thrust.

[0077] Specifically, the positions of the loading structure 40 and the first sensor 31 are set such that the first sensor 31 can accurately measure the thrust provided by the loading structure 40, thereby improving the accuracy and reliability of the calibration of the torque limiter 20 by the calibration device.

[0078] The second sensor 32 includes a sensor body 33 and a pull rope 34 for measuring displacement calibration data.

[0079] The sensor body 33 is disposed on one of the first structure 11 and the second structure 12. The pull rope 34 is connected to the sensor body 33 and is also connected to the other of the first structure 11 and the second structure 12.

[0080] In a specific embodiment, the second sensor 32 may be a wire-type displacement sensor, including a sensor and a pull rope 34. The sensor body 33 and the pull rope 34 are connected and are respectively disposed on the first structure 11 and the second structure 12. Since the first structure 11 and the driving flange 21 move synchronously during the calibration process, and the second structure 12 and the driven flange 22 are fixed to the fixing member 50, the displacement of the driving flange 21 can be accurately measured. Specifically, the sensor body 33 may be disposed on the side of the first structure 11 close to the driven flange 22, for example, disposed on the second connecting portion 15.

[0081] In addition, the control structure 60 is further configured to obtain time calibration data and determine the movement speed of the driving flange 21 according to the time calibration data and the displacement calibration data.

[0082] In a specific embodiment, the control structure 60 is electrically connected to the measuring structure 30. Specifically, the control structure 60 is electrically connected to the first sensor 31 and the second sensor 32 respectively and may be fixed on the fixing member 50.

[0083] In addition to processing the measurement calibration data obtained during the calibration of the torque limiter 20, the control structure 60 can also monitor the time during the calibration process to generate time calibration data, and cooperate with the displacement calibration data to determine the movement speed of the driving flange 21 when the torque limiter 20 is overloaded, thereby improving the comprehensiveness of the calibration process of the torque limiter 20.

[0084] In the embodiment of the present invention, when calibrating the torque limiter 20, the torque limiter 20 can correspond to multiple calibration devices. For example, two calibration devices can be used to calibrate the torque limiter 20. As Figure 4 shown, the two calibration devices are symmetrically distributed along the center of the torque limiter 20 to achieve synchronous and uniform loading of thrust on the torque limiter 20.

[0085] In addition, the torque limiter 20 is placed parallel to the fixing member 50. For example, when the test bench is a horizontal plane, the torque limiter 20 is fixed parallel to the surface of the test bench through the fixing member 50. Compared with the vertical calibration of the torque limiter 20 in the related art, this calibration device can achieve horizontal calibration, has strong compatibility with torque limiters 20 of different models with large torque and large diameter, is not restricted by dimensions such as the outer diameter and center height of the torque limiter 20, and there is no need to additionally build a test bench every time calibrating torque limiters of different models and different sizes, which is conducive to reducing the time cost and economic cost in the calibration process.

[0086] Correspondingly, the technical solution of the present application also discloses a calibration method, which is applied to the calibration device in any of the above embodiments. As Figure 5 shown, a calibration method includes:

[0087] Step S1: Connect the torque limiter to the calibration device;

[0088] In a specific embodiment, the torque limiter is placed on the fixing member of the calibration test bench or operating table and fixed to the fixing member through the driven flange and the second structure. Further, the first structure is connected to the driving flange.

[0089] Specifically, in order to provide uniform thrust for the torque limiter, the number of calibration devices can be set to two, which are respectively symmetrically arranged at both ends of the torque limiter and fixed to the fixing member.

[0090] Step S2: Apply thrust to the torque limiter multiple times, and obtain multiple measurement calibration data corresponding to each thrust application process; the measurement calibration data includes torque calibration data, displacement calibration data, and time calibration data;

[0091] In a specific embodiment, the loading structure provides thrust in the tangential direction consistent with the driving flange, and makes the thrust be transmitted to the driving flange along the first structure by pushing against the first sensor, and measures the torque calibration data through the first structure. At the same time, since the first structure moves under the action of the thrust, the sensor body of the second sensor installed on the first structure moves away from the pulling rope, so as to realize the measurement of displacement calibration data.

[0092] Specifically, for a single calibration process of a thimble, different pushing forces can be applied to it slowly and uniformly. When it is overloaded, a torque calibration data, a displacement calibration data, and a time calibration data can be obtained. Further, reset the positions of the reset loading device and the driving flange, and reset multiple thimbles through the thimble reset device, and continue to operate and record once according to the foregoing process. Take the average value of the disengagement torques of the two tests to obtain the average torque calibration data, the average displacement calibration data, and the average time calibration data corresponding to a single calibration process of the thimble.

[0093] For the remaining thimbles, repeat the above process until all thimbles are calibrated, and obtain multiple average torque calibration data, multiple average displacement calibration data, and multiple average time calibration data corresponding to the torque limiter.

[0094] Step S3: Process multiple measurement calibration data to obtain target calibration data; the target calibration data includes the mean calibration torque and the target response speed.

[0095] Processing multiple measurement calibration data to obtain target calibration data includes:

[0096] Perform mean processing on multiple torque calibration data to obtain the mean calibration torque;

[0097] Based on multiple displacement calibration data and multiple time calibration data, calculate the target response speed.

[0098] In a specific embodiment, send multiple average torque calibration data and multiple average displacement calibration data to the control structure, so that the control structure performs mean processing on the multiple average torque calibration data to obtain the mean calibration torque. And, the control structure combines the average time calibration data it obtains and the average displacement calibration data received from the second sensor to calculate the target response speed. The target response speed is the movement speed of the driving flange during overload, and overload means that the torque reaches the set threshold of the torque limiter.

[0099] Through the above calibration method, accurate calibration of the torque limiter can be achieved, the calibration process of the torque limiter is simplified, the operation complexity of the calibration process is reduced, and thus it is beneficial to reduce the time cost and economic cost required during the calibration of the torque limiter.
