These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0055] Before introducing the embodiments of this application, the terms involved in this application will be explained first:

[0056] Fasteners: refer to a class of mechanical parts used to fasten two or more parts (or components) together as a whole, including bolts, studs, screws, nuts, etc.

[0057] Mechanical chucks: refer to the parts in a chuck used to hold and clamp workpieces in a mechanical structure, or machine tool accessories used to clamp and position workpieces.

[0058] Dual-sided torque balancing: refers to a control method that maintains balance by adjusting the torque on both sides of the fastener.

[0059] Secondly, the application background of the embodiments of this application will be explained:

[0060] Dual-sided torque balancing has important applications in industrial equipment use and power equipment installation. Ensuring the uniformity of force on both sides of the fasteners is not only related to the long-term reliability of the power equipment, but also directly affects the safety and service life of the equipment structure.

[0061] Traditional balancing and fastening methods mainly rely on manual experience or static parameter settings. The torque is determined by the operator's work experience before the fastener is tightened. Static parameters are set according to standard specifications and based on known material properties and usage conditions, thereby instructing the operator on the execution standards.

[0062] Existing balancing fastening methods require a significant amount of time to tighten fasteners based on human experience, and manual adjustments may introduce errors, resulting in low tightening efficiency and quality.

[0063] The dual-sided torque-balanced fastening system provided in this application aims to solve the aforementioned technical problems of the prior art. The inventive concept of this application is as follows: Determining whether a fastener is in a tightened state typically requires applying a tightening force in the tightening direction to the front screw and the back nut of the fastener. This applied force can generally be represented by a rotational torque value. If the rotational torque values ​​of the front screw and the back nut can be collected, it can be determined whether the front screw and the back nut are in a tightened state based on the rotational torque values. Furthermore, by using a coordinated fastening device to accurately collect the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut of the fastener, and by using a dynamic adjustment device to adjust the front screw and the back nut according to the torque difference between the first and second rotational torque values, the adjusted torque difference is kept within a preset range, ensuring that the front screw and the back nut of the fastener are in a torque-balanced state, which can effectively improve the efficiency and quality of fastening.

[0064] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0065] Figure 1 Schematic diagram of the dual-sided torque-balanced fastening system provided in the embodiments of this application Figure 1 .like Figure 1 As shown, the dual-sided torque-balanced fastening system includes: a co-fastening device and a dynamic adjustment device;

[0066] The following execution logic applies to this dual-sided torque-balanced fastening system:

[0067] Step 1: Use a coordinated fastening device to fix the front screw and the back nut in the fastener to be fastened, and collect the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut;

[0068] For example, the co-fastening device is connected to the fastener to fix the front screw and the back nut in the fastener, and based on the fixed connection with the front screw and the back nut in the fastener, a first rotational torque value applied to the front screw and a second rotational torque value applied to the back nut are collected respectively.

[0069] In one possible implementation, each fastener is connected and fixed to a co-fastening device.

[0070] In one possible implementation, the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut can be acquired in real time by a torque sensor installed within the co-fastening device.

[0071] The collaborative fastening device can transmit the first and second rotational torque values ​​collected in real time to the dynamic adjustment device through the data transmission unit set in the collaborative fastening device.

[0072] Step 2: The dynamic adjustment device adjusts the front screw and the back nut according to the torque difference between the first rotational torque value and the second rotational torque value, so that the adjusted torque difference is within the preset difference range.

[0073] The preset difference range is used to indicate the torque difference range when the front screw and the back nut are in a tightened state.

[0074] For example, after receiving the first and second rotational torque values ​​collected by the co-fastening device, the dynamic adjustment device calculates the torque difference between the first and second rotational torque values, and adjusts the front screw and the back nut according to a preset difference range for indicating the torque difference range of the front screw and the back nut being in a tightened state, so that the adjusted torque difference is within the preset difference range.

[0075] In one possible implementation, the first and second rotational torque values ​​collected by the co-fastening device can be received by a data receiving unit installed within the dynamic adjustment device. Correspondingly, the data receiving unit installed within the dynamic adjustment device and the data transmission unit installed within the co-fastening device can be connected via wired or wireless connection to enable data reception and transmission.

[0076] In addition, the dynamic adjustment device is equipped with a balance analysis unit to calculate the torque difference between the first rotational torque value and the second rotational torque value and to compare whether the torque difference is within a preset range.

[0077] The front screw and back nut are adjusted by the actuator in the dynamic adjustment device. The actuator can be a motor or a hydraulic motor connected to the front screw and back nut. The front screw and back nut can be adjusted by adjusting the motor speed or the hydraulic pressure of the hydraulic motor.

[0078] In one possible implementation, after adjusting the front screw and the back nut, a co-tightening device collects the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut after adjustment, and sends them to a dynamic adjustment device. The torque difference between the adjusted first rotational torque value and the second rotational torque value is compared with a preset difference range until the adjusted torque difference is within the preset difference range, which indicates that the front screw and the back nut are in a tightened state.

[0079] The dual-sided torque balancing fastening system provided in this application includes a co-fastening device and a dynamic adjustment device. First, the co-fastening device secures the front screw and the back nut in the fastener to be fastened, and collects a first rotational torque value applied to the front screw and a second rotational torque value applied to the back nut. Then, the dynamic adjustment device adjusts the front screw and the back nut according to the torque difference between the first and second rotational torque values, so that the adjusted torque difference is within a preset difference range. The preset difference range indicates the range of torque differences within which the front screw and the back nut are in a tightened state. In this embodiment, the coordinated fastening device can accurately fix the front screw and the back nut in the fastener, and can collect the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut in real time, so that the system can accurately determine the fastening state of the front screw and the back nut. Through the dynamic adjustment device, the front screw and the back nut can be adjusted according to the torque difference between the first rotational torque value and the second rotational torque value and the preset difference range, so that the adjusted torque difference is within the preset difference range, that is, the front screw and the back nut are adjusted to be in a fastened state, which can effectively improve the efficiency and quality of fastening.

[0080] Based on the above embodiments, Figure 2 Schematic diagram of the dual-sided torque-balanced fastening system provided in the embodiments of this application Figure 2 .like Figure 2 As shown, the dual-sided torque-balanced fastening system also includes a remote control platform, which includes a data storage unit.

[0081] Accordingly, based on the above structure, the following operations can be performed:

[0082] The data storage unit acquires in real time the torque difference between the first and second rotational torque values, as well as the adjustment results;

[0083] The adjustment result is used to indicate whether the front screw and the back nut are in a tightened state.

[0084] For example, the dual-sided torque balancing fastening system also includes a remote control platform, which includes a data storage unit. The remote control platform is connected to a dynamic adjustment device, and the data storage unit included in the remote control platform acquires in real time the torque difference between the first rotational torque value and the second rotational torque value, as well as the adjustment results used to indicate whether the front screw and the back nut are in a tightened state.

[0085] In one possible implementation, the remote control platform and the dynamic adjustment device can be connected via wired or wireless connection to enable data acquisition and storage.

[0086] When the dynamic adjustment device adjusts the front screw and the back nut according to the torque difference between the first and second rotational torque values, it can connect to the data storage unit of the remote control platform through the data transmission unit set in the dynamic adjustment device. The data storage unit can then obtain the torque difference between the first and second rotational torque values ​​and the adjustment result in real time.

[0087] In addition, the data storage unit can also store the torque difference between the first and second rotational torque values, as well as the adjustment results, for further analysis and processing.

[0088] The dual-sided torque balancing fastening system provided in this application embodiment further includes a remote control platform, which includes a data storage unit. The data storage unit acquires in real-time the torque difference between a first rotational torque value and a second rotational torque value, as well as the adjustment result. The adjustment result indicates whether the front screw and the back nut are in a tightened state. In this embodiment, by acquiring the torque difference between the first and second rotational torque values ​​in real-time through the data storage unit of the remote control platform, the tightening process of the front screw and the back nut can be accurately monitored. Real-time data acquisition ensures that the system can detect torque differences in a timely manner, helping to make necessary adjustments to ensure that the front screw and the back nut are in a tightened state.

[0089] Based on the above embodiments, Figure 3 Schematic diagram of the dual-sided torque-balanced fastening system provided in the embodiments of this application Figure 3 .like Figure 3 As shown, the remote control platform also includes: a parameter configuration unit and a configuration synchronization unit;

[0090] Accordingly, based on the above structure, the following operations can be performed:

[0091] Step 1: The parameter configuration unit responds to the user's configuration operation and adjusts the values ​​within the preset difference range;

[0092] For example, the remote control platform of the dual-sided torque balance fastening system also includes a parameter configuration unit. When the user performs a configuration operation on the remote control platform, the parameter configuration unit responds and adjusts the value of the preset difference range according to the user's configuration operation.

[0093] In one possible implementation, users can customize parameter configuration based on the parameter configuration unit according to the fastening requirements of fasteners of different specifications or different fastening task requirements, and flexibly adjust the value of the preset difference range according to the customized parameter configuration.

[0094] Step 2: Configure the synchronization unit to send the adjusted preset difference range to the dynamic adjustment device.

[0095] For example, the remote control platform of the dual-sided torque balance fastening system also includes a configuration synchronization unit. When the parameter configuration unit adjusts the value of the preset difference range, the configuration synchronization unit obtains the adjusted preset difference range and sends it to the dynamic adjustment device so that the dynamic adjustment unit configures the adjusted preset difference range.

[0096] In one possible implementation, the configuration synchronization unit is connected to the data transmission unit set within the dynamic adjustment device, and the adjusted preset difference range is sent to the dynamic adjustment device, where it is received by the data transmission unit set within the dynamic adjustment device.

[0097] The dual-sided torque balancing fastening system provided in this application embodiment includes a remote control platform that further comprises a parameter configuration unit and a configuration synchronization unit. First, the parameter configuration unit responds to the user's configuration operation by adjusting the value of a preset difference range. Then, the configuration synchronization unit sends the adjusted preset difference range to the dynamic adjustment device. In this embodiment, by introducing a parameter configuration unit into the remote control platform, the user can freely adjust the preset difference range, achieving flexible and precise parameter configuration for different fastening tasks and ensuring that the fastening process meets various operational requirements. By introducing a configuration synchronization unit into the remote control platform, the value of the preset difference range set by the user in the parameter configuration unit can be quickly and accurately synchronized to the dynamic adjustment device, thereby optimizing the entire fastening process and improving product quality and production efficiency.

[0098] Based on the above embodiments, Figure 4 Schematic diagram of the dual-sided torque-balanced fastening system provided in the embodiments of this application Figure 4 .like Figure 4 As shown, the collaborative fastening device includes: a magnetic adsorption unit, a mechanical jaw unit, a first torque sensor, and a second torque sensor;

[0099] Accordingly, based on the above structure, the following operations can be performed:

[0100] Step 1: The magnetic adsorption unit and the mechanical claw unit are used to adsorb and fix the front screw and the back nut, respectively;

[0101] For example, the magnetic adsorption unit and the mechanical claw unit are connected to the front screw and the back nut, respectively, for adsorbing and fixing the front screw and the back nut.

[0102] In one possible implementation, the magnetic adsorption unit incorporates a strong magnetic material that adheres to the metal surfaces of the front screw and the back nut, and is fixed by magnetic force.

[0103] The mechanical gripper unit uses a physical method, employing a mechanical gripper structure to hold the external structure of the front screw and the back nut in place for fixation.

[0104] In addition, the mechanical gripper unit can be adjusted according to the different sizes of the front screw and the back nut. Through the metal mechanical gripper with a certain degree of elasticity, it tightly clamps the outside of the front screw and the back nut, generating sufficient friction to achieve precise fixing.

[0105] The number of mechanical gripper units can also be expanded according to actual needs. For example, in this embodiment, two mechanical gripper units are set, which can respectively fix the front screw and the back nut.

[0106] Step 2: The first torque sensor is used to obtain the first rotational torque value of the front screw;

[0107] For example, the collaborative fastening device acquires the first rotational torque value of the front screw in real time through a built-in first torque sensor.

[0108] In one possible implementation, by connecting a first torque sensor to the drive end of the front screw (such as an electric screwdriver or wrench), the first rotational torque value of the front screw during the tightening process can be acquired.

[0109] For example, the first torque sensor can be a strain gauge torque sensor, which calculates torque by sensing the minute deformation of the front screw when it is subjected to force. It is usually required to be installed at the location where the force is directly applied.

[0110] Step 3: The second torque sensor is used to obtain the second rotational torque value of the rear nut.

[0111] For example, the collaborative fastening device acquires the first rotational torque value of the back nut in real time through a built-in second torque sensor.

[0112] In one possible implementation, a second torque sensor is placed at the thread of the back nut to sense the torque generated when the back nut rotates, thereby acquiring the second rotational torque value of the back nut during the tightening process.

[0113] For example, the second torque sensor can also be a strain gauge torque sensor.

[0114] The dual-sided torque-balanced fastening system provided in this application embodiment includes a magnetic adsorption unit, a mechanical jaw unit, a first torque sensor, and a second torque sensor. The magnetic adsorption unit and the mechanical jaw unit are used to adsorb and fix the front screw and the back nut, respectively. The first torque sensor is used to obtain the first rotational torque value of the front screw, and the second torque sensor is used to obtain the second rotational torque value of the back nut. In this embodiment, the front screw and the back nut are fixed by the combined use of the magnetic adsorption unit and the mechanical jaw unit, ensuring that the front screw and the back nut do not shift or loosen during the fastening process, making the entire fastening process more stable and precise. By collecting the first and second rotational torque values ​​of the front screw and the back nut, respectively, the dual-sided torque-balanced fastening system can monitor the torque changes during the fastening process in real time, thereby promptly detecting any abnormal phenomena during the fastening process and improving fastening efficiency.

[0115] Figure 5 A flowchart illustrating the dual-sided torque-balanced fastening method provided in this application embodiment. Figure 1 .like Figure 5 As shown, this dual-sided torque balancing fastening method is applied to the dynamic adjustment device in a dual-sided torque balancing fastening system. The method includes the following steps:

[0116] S510, Obtain the first rotational torque value applied to the front screw in the fastener and the second rotational torque value applied to the back nut in the fastener.

[0117] In this step, the dynamic adjustment device obtains a first rotational torque value applied to the front screw and a second rotational torque value applied to the back nut of the fastener, so that the front screw and the back nut can be tightened subsequently based on the first and second rotational torque values.

[0118] In one possible implementation, the data receiving unit in the dynamic adjustment device is connected to the data transmission unit in the collaborative fastening device via a wired or wireless connection to obtain the first rotational torque value and the second rotational torque value.

[0119] For example, the collaborative fastening device collects the first rotational torque value T1 applied to the front screw of the fastener and the second rotational torque value T2 applied to the back nut of the fastener, which is obtained by the dynamic adjustment device.

[0120] S520. Based on the torque difference between the first rotational torque value and the second rotational torque value, adjust the front screw and the back nut so that the adjusted torque difference is within the preset difference range.

[0121] The preset difference range is used to indicate the torque difference range when the front screw and the back nut are in a tightened state.

[0122] In this step, the first rotational torque value and the second rotational torque value are subtracted to obtain the torque difference between the first rotational torque value and the second rotational torque value. Based on the torque difference, the front screw and the back nut are adjusted so that the adjusted torque difference is within a preset difference range, that is, the torque difference range used to indicate that the front screw and the back nut are in a tightened state.

[0123] In one possible implementation, the torque difference between the first rotational torque value and the second rotational torque value can be obtained by subtracting the first rotational torque value and taking the absolute value.

[0124] For example, if the first rotational torque value is T1 and the second rotational torque value is T2, then the torque difference between the first rotational torque value and the second rotational torque value can be ΔT=|T1-T2|.

[0125] In one possible implementation, the preset difference range can be 0-δ. The torque difference between the first rotational torque value and the second rotational torque value is compared with the preset difference range. The comparison result can be that the torque difference is within the preset difference range, which indicates that the front screw and the back nut are in a tightened state. Alternatively, the comparison result can be that the torque difference exceeds the preset difference range, which indicates that the front screw and the back nut are not in a tightened state.

[0126] For example, when ΔT is less than or equal to δ, that is, the torque difference is within the preset difference range, it means that the front screw and the back nut are in a tightened state; when ΔT is greater than δ, that is, the torque difference exceeds the preset difference range, it means that the front screw and the back nut are not in a tightened state.

[0127] In one possible implementation, the dual-sided torque-balanced fastening method further includes the following:

[0128] The first method is to generate a first alarm message if the first rotational torque value and / or the second rotational torque value are less than the preset lower limit of the torque value.

[0129] The first alarm message is used to indicate that the front screw and / or the back nut are under-torque.

[0130] For example, a preset lower limit of torque value is used to indicate the generation of a first alarm message. When the first rotational torque value and / or the second rotational torque is less than the preset lower limit of torque value, a first alarm message is generated to indicate that the front screw and / or the back nut are in a torque underload state.

[0131] For example, if the preset lower limit of the torque value is Td, and the first rotational torque value T1 and / or the second rotational torque value T2 are less than Td, it indicates that the front screw and / or the back nut are in a torque underload state.

[0132] The second method is to generate a second alarm message if the first rotational torque value and / or the second rotational torque value are greater than the preset upper limit of the torque value.

[0133] The second alarm message is used to indicate that the front screw and / or the back nut are in a torque overload state.

[0134] For example, a preset torque value upper limit is used to indicate the generation of a second alarm message. When the first rotational torque value and / or the second rotational torque is greater than the preset torque value upper limit, a second alarm message is generated to indicate that the front screw and / or the back nut are in a torque overload state.

[0135] For example, if the preset upper limit of torque value is Tu, and the first rotational torque value T1 and / or the second rotational torque value T2 are greater than Tu, it indicates that the front screw and / or the back nut are in a torque overload state.

[0136] In one possible implementation, the first alarm information and / or the second alarm information may also include the position information of the front screw and / or the back nut.

[0137] For example, the position information of the front screw and / or the back nut in the first alarm message and / or the second alarm message usually refers to the specific coordinates, position status or azimuth of the front screw and / or the back nut in the entire working area.

[0138] For example, the position information of the front screw and / or the back nut can be the specific location in the three-dimensional space corresponding to the entire working area, which can be described by XYZ coordinates;

[0139] The position information of the front screw and / or the back nut can also be the offset or rotation angle relative to the target reference position.

[0140] The dual-sided torque balancing fastening method provided in this application embodiment is applied to a dynamic adjustment device in a dual-sided torque balancing fastening system. First, it acquires a first rotational torque value applied to the front screw and a second rotational torque value applied to the back nut of the fastener. Then, based on the torque difference between the first and second rotational torque values, it adjusts the front screw and the back nut so that the adjusted torque difference falls within a preset range. This preset range indicates the range of torque differences within which the front screw and the back nut are in a tightened state. In this embodiment, by acquiring the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut, the tightening state of the front screw and the back nut in the fastener can be accurately monitored in real time. By adjusting the front screw and the back nut based on the torque difference between the first and second rotational torque values, automatic adjustment of the front screw and the back nut can be achieved, maintaining them in a tightened state and effectively improving the balancing fastening efficiency and accuracy of the fastener.

[0141] Based on the above embodiments, Figure 6 A flowchart illustrating the dual-sided torque-balanced fastening method provided in this application embodiment. Figure 2 .like Figure 6 As shown, a possible implementation of step S520 above also includes the following steps:

[0142] S610, Determine the torque difference between the first rotational torque value and the second rotational torque value.

[0143] In this step, the first rotational torque value and the second rotational torque value are subtracted to obtain the torque difference value.

[0144] In one possible implementation, the torque difference between the first rotational torque value and the second rotational torque value can be determined by directly subtracting the first rotational torque value and the second rotational torque value, or by taking the absolute value after subtraction.

[0145] For example, if the first rotational torque value is T1 and the second rotational torque value is T2, when T1 is greater than T2, the torque difference between the first rotational torque value and the second rotational torque value can be ΔT = T1 - T2.

[0146] When T1 is less than T2 (i.e., T2 is greater than T1), the torque difference between the first rotational torque value and the second rotational torque value can be either ΔT=|T1-T2| or ΔT=T2-T1.

[0147] S620. If the torque difference is not within the preset difference range, a preset control strategy is adopted to adjust the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut until the torque difference between the adjusted first rotational torque value and the adjusted second rotational torque value is within the preset difference range.

[0148] The preset control strategy includes: increasing the first preset torque value applied to the front screw and increasing the second preset torque value applied to the back nut, wherein the first preset torque value is less than the second preset torque value.

[0149] In this step, a control strategy is preset to adjust the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut when the torque difference is not within a preset difference range. This results in the adjusted first and second rotational torque values. The torque difference between the adjusted first and second rotational torque values ​​is then compared with a preset difference range until the torque difference between the adjusted first and second rotational torque values ​​falls within the preset difference range, at which point the adjustment is complete.

[0150] In one possible implementation, when the torque difference is not within the preset difference range, it can be that the difference between the first rotational torque value and the second rotational torque value is greater than the upper limit of the preset difference range. In this case, the first preset torque value, which is less than the second preset torque value, can be increased on the front screw, and the second preset torque value can be increased on the back nut, so as to reduce the difference between the first rotational torque value and the second rotational torque value.

[0151] For example, when the first rotational torque value T1 of the front screw is greater than the second rotational torque value T2 of the back nut, the torque difference ΔT = T1 - T2. Then, according to the preset control strategy, the second preset torque value is increased and applied to the back nut, while the first preset torque value, which is less than the second preset torque value, is increased on the front screw until the torque difference ΔT is within the preset difference range, and the adjustment is completed.

[0152] The dual-sided torque balancing fastening method provided in this application first determines the torque difference between a first rotational torque value and a second rotational torque value. If the torque difference is not within a preset difference range, a preset control strategy is adopted to adjust the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut until the torque difference between the adjusted first and second rotational torque values ​​is within the preset difference range. The preset control strategy includes increasing the first preset torque value applied to the front screw and increasing the second preset torque value applied to the back nut, where the first preset torque value is less than the second preset torque value. In this embodiment, by comparing the torque difference between the first and second rotational torque values ​​with the preset difference range, the fastening state of the front screw and the back nut can be effectively determined. Through the preset control strategy, when the torque difference is not within the preset difference range, the first rotational torque value applied to the front screw and the second rotational torque value applied to the back nut can be automatically adjusted, accelerating the adjustment speed of the fastener torque during the fastening process and thus improving the efficiency of balanced fastening.
