[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Example 1, reference Figure 1 - Figure 2 , which is the first embodiment of the present invention, provides an adaptive electric torque wrench for transmission tower assembly, including a torque wrench 101 and an adaptive sleeve 102. The adaptive sleeve 102 is designed with a special structure built-in torque sensor 102b and an electronic display screen 102a. It can detect the peak value of the torque value during the process of tightening and removing the nut. The sensor detects and displays the real-time torque value on the screen during the process of tightening and removing the bolts and nuts. At the same time, the adaptive sleeve can be used as a torque calibration device, and various wrenches can be calibrated at any time. It can automatically adapt to bolts of different specifications, which improves the versatility of the wrench. The interior of the sleeve is made of high-strength material, which has good wear resistance and impact resistance, and can extend the service life.

[0031] The sleeve body is made of high-strength alloy steel with good wear resistance and impact resistance. An elastic bushing and a clamping device are provided inside the sleeve. The clamping device adopts a threaded adjustment structure. By rotating the clamping nut, the tightness of the sleeve and the bolt can be further fine-tuned to ensure sufficient friction between the sleeve and the bolt during the tightening process, thereby improving the versatility of the sleeve.

[0032] Example 2, reference Figure 1 - Figure 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it includes a torque regulation module 201, a power drive module 202 and an operation control module 203. The torque regulation module 201 is a core control unit 200, which is mainly composed of a high-performance microcontroller 201a, a signal conditioning circuit 201b, an analog-to-digital converter 201c and a power management circuit 201d. The microcontroller 201a has a built-in special algorithm program for processing the signal received from the torque sensor 102b, and sends precise control instructions to the power drive module 202 according to the preset torque value and bolt specification parameters to achieve automatic adjustment of torque; the signal conditioning circuit 201b is responsible for amplifying, filtering and linearizing the weak analog signal from the torque sensor 102b to ensure the quality and accuracy of the signal for subsequent analog-to-digital conversion and processing by the microcontroller 201a; the analog-to-digital converter 201c converts the analog signal after signal conditioning into a digital signal so that the microcontroller 201a can perform digital operations and processing; the power management circuit 201d: provides a stable DC power supply for the entire device.

[0033] Furthermore, the power drive module 202 includes a motor controller 202a, an electric motor 202b, a precision reduction mechanism 202c and a drive output shaft 202d. The microcontroller 201a of the torque adjustment module 201 is connected to the electric motor 202b controller 202a of the power drive module 202 via a control signal line. When the torque adjustment module 201 needs to adjust the torque value, the microcontroller 201a will send a control instruction to the electric motor 202b controller 202a. The motor controller 202a is one of the control centers of the entire electric torque wrench 101 system. It receives instructions from the microcontroller 201a and controls the start, stop, speed and direction of the electric motor 202b according to these instructions. The electric motor 202b is the executive component of the motor controller 202a. It works according to the instructions of the motor controller 202a. It converts electrical energy into mechanical energy and generates rotational motion. The motor controller 202a is connected to the electric motor 202b through wires to provide power and control signals. The output shaft of the electric motor 202b is connected to the input shaft of the torque adjustment module 201 through a coupling.

[0034] Among them, the precision reduction mechanism 202c is located between the output shaft of the electric motor 202b and the drive output shaft 202d, and is used to reduce the rotation speed and increase the torque to meet the working requirements of the torque wrench 101. The output shaft of the electric motor 202b is connected to the input end of the precision reduction mechanism 202c through a coupling, and the output end of the precision reduction mechanism 202c is connected to the drive output shaft 202d through a similar connection method. The drive output shaft 202d is the final execution component of the system. It is directly connected to the adaptive sleeve 102 of the wrench, and transmits the decelerated rotational motion to the adaptive sleeve 102 to achieve the tightening or loosening of the bolt.

[0035] Furthermore, the operation control module 203 is located at the handle of the wrench, and is mainly composed of an operation button 203a and a memory 203b. The LCD screen 102a is used to intuitively display the current torque value, speed, working mode and other information, so that the user can understand the working status of the wrench in real time. The operation button 203a includes a torque value increase button, a torque value decrease button, a speed adjustment button, a mode switching button, etc., and the user can easily set and adjust parameters such as torque value and speed through these buttons.

[0036] During use, when the torque wrench 101 is used to assemble a transmission tower, the adaptive sleeve 102 is first installed on the bolt. The torque adjustment module 201 monitors the tightening degree of the bolt and the working state of the wrench in real time through a sensor, and automatically adjusts the torque value according to the preset parameters. The power drive module 202 provides power to drive the sleeve to rotate and tighten the bolt. The operation control module facilitates the user to set parameters and control operations to ensure that the wrench works safely and reliably.

[0037] The remaining structures are the same as those of Example 1.

[0038] Example 3, reference Figure 1 - Figure 3 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: compared with embodiment 2, a method for using an adaptive electric torque wrench 101 for assembling a transmission tower is provided, comprising: in an installation stage, installing an adaptive sleeve 102 on the torque wrench 101, calibrating the torque sensor 102b using a known standard torque value to ensure measurement accuracy, confirming the calibration status of the torque sensor 102b through a display screen 102a, and the display screen 102a accurately displays the real-time torque value;

[0039] In the adjustment stage, the initial torque value is set according to the bolt specifications and assembly requirements, the speed of the electric motor 202b is adjusted by operating the button 203a, and the commonly used torque value and speed parameters are saved in the memory 203b so as to be quickly called up next time;

[0040] During the use phase, the power drive module 202 is started, and the electric motor 202b starts working to provide power output. The torque value, speed and working mode are monitored in real time through the display screen 102a. Under the control of the torque adjustment module 201, the electric motor 202b drives the sleeve to rotate and tightens the bolt until the preset torque value is reached. When the preset torque value is reached, the system will automatically stop or slow down the tightening operation.
