[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 4 As shown, an embodiment of the present invention provides a visualized bolt tightening device, including a base 10, a steering portion 20, an electric wrench 30, an image acquisition unit 40 and a remote control unit, wherein the steering portion 20 is mounted on the base 10, the electric wrench 30 is mounted on the steering portion 20, the steering portion 20 is used to adjust the position of the electric wrench 30, the image acquisition unit 40 is mounted on the electric wrench 30, the image acquisition unit 40 is used to acquire an image of an operating area, the image acquisition unit 40 and the steering portion 20 are both electrically connected to the remote control unit, the remote control unit displays the image acquired by the image acquisition unit 40, the operator operates the remote control unit according to the displayed image, and the remote control unit controls the steering portion 20 to move so that the electric wrench 30 is aligned with the bolts in the operating area.

[0030] In this embodiment, the image acquisition unit 40 installed on the electric wrench 30 can capture images of the operating area in real time, such as the position, shape, and state of the bolts, and transmit the images to the remote control unit for display, so that the operator does not need to rely on his own experience to judge the condition of the bolts, and can observe the bolts and the surrounding environment in real time, thereby accurately judging the alignment of the electric wrench 30. The remote control unit can also control the action of the steering part 20 to accurately adjust the position of the electric wrench 30 to ensure that the electric wrench 30 is aligned with the target bolt, which can reduce the deviation of manual operation, ensure the correct tightening of the bolts, and improve work efficiency. In addition, this also reduces the situation where the operator needs to bend over or bow his head to confirm, reduces accidental injuries caused by improper operation or fatigue, and improves work safety.

[0031] like Figure 3 As shown, the electric wrench 30 includes a wrench body 31 and a sleeve 32 installed on the wrench body 31, and the image acquisition unit 40 is installed on the wrench body 31 or the sleeve 32. The image acquisition unit 40 includes a camera and a wireless transmission module. The camera is used to capture images of the operating area, and the wireless transmission module is used to transmit the captured images to the remote control unit.

[0032] In this embodiment, the camera can capture images of the operating area in real time, including the bolt position, the surrounding environment, and details of the operation process. Through the high-precision image acquisition of the camera and the wireless transmission module to transmit the image to the remote control unit, the operator can clearly see the specific position and status of the target bolt on the remote control unit, which can help the operator accurately determine the relative position of the sleeve 32 and the bolt, thereby reducing the chance of alignment errors and ensuring the correct tightening of the bolt.

[0033] Furthermore, the image acquisition unit 40 can not only transmit images in real time, but also record images of each operation. By archiving the images, the operator can review the specific circumstances of each tightening operation, providing an important reference for subsequent operations and maintenance.

[0034] Furthermore, the visual bolt tightening device also includes a remote control receiving module and a control module. The remote control receiving module is arranged on the base 10 or the steering part 20. The remote control receiving module receives the control signal sent by the remote control unit and transmits the control signal to the control module. The control module controls the steering part 20 and the electric wrench 30 to move according to the control signal.

[0035] In this embodiment, the remote control receiving module receives the control signal sent by the remote control unit and quickly transmits it to the control module, which can ensure the immediacy and efficiency of signal transmission, and the operator can control the movement of the steering part 20 and the electric wrench 30 in real time, and ensure the timeliness and accuracy of the operation feedback. Moreover, through the coordinated work of the remote control unit and the control module, the operator does not need to manually intervene in the adjustment position or movement of the electric wrench 30, but only needs to issue instructions, which can simplify the operation process.

[0036] Specifically, the control module includes a first control panel and a second control panel, both of which are electrically connected to the remote control receiving module. The first control panel is installed on the base 10 or the steering part 20, and the first control panel is used to control the steering part 20. The second control panel is installed on the base 10 or the electric wrench 30, and the second control panel is used to control the electric wrench 30. The remote control unit includes a display screen and a remote control transmitting module. The display screen is used to display the image captured by the image acquisition unit 40, and the remote control transmitting module is operated by the operator to send a control signal.

[0037] In this embodiment, the first control panel is responsible for controlling the steering part 20, and the second control panel is responsible for controlling the electric wrench 30. The two independently manage different components, but coordinate work through the remote control receiving module. Such separate control can make the operation more accurate and efficient, and can also avoid the problem of unsmooth operation caused by a single controller. The display screen of the remote control unit can display the operation area image acquired by the image acquisition unit 40 in real time, helping the operator to understand the position and operation status of the electric wrench 30 and the bolt. Through the display screen, the operator can monitor the operation process at any time to ensure that the electric wrench 30 is accurately aimed at the target bolt. Moreover, through the remote control transmitting module, the operator can easily send different control instructions, which improves the operation efficiency and convenience of operation.

[0038] like Figure 4 As shown, the steering part 20 includes a first steering mechanism 21 and a second steering mechanism 22, the first steering mechanism 21 is installed on the base 10, the second steering mechanism 22 is installed on the first steering mechanism 21, and the electric wrench 30 is installed on the second steering mechanism 22; wherein, the first steering mechanism 21 is used to control the second steering mechanism 22 and the electric wrench 30 to swing around a first axis, and the second steering mechanism 22 is used to control the electric wrench 30 to swing around a second axis, and the second axis is perpendicular to the first axis.

[0039] In this embodiment, through the cooperation of the first steering mechanism 21 and the second steering mechanism 22, the electric wrench 30 can freely swing around the first axis and the second axis, so that the positioning of the electric wrench 30 in space is more flexible, and the ideal position of the bolt can be accurately adjusted, avoiding the limitations that may be caused by single axis control. It can also avoid frequent manual adjustment of the position of the electric wrench 30 in traditional operations, saving time, reducing the labor intensity of operators, and improving work efficiency.

[0040] Specifically, the first steering mechanism 21 includes a first driving mechanism, a first transmission mechanism, a first rotating shaft 211 and a first rotating body 212. The first driving mechanism is fixedly installed on the base 10, the first rotating shaft 211 is rotatably installed on the base 10, the first driving mechanism drives the first rotating shaft 211 to swing through the first transmission mechanism, the first rotating body 212 is connected to the first rotating shaft 211, the first rotating shaft 211 drives the first rotating body 212 to swing, and the second steering mechanism 22 is installed on the first rotating body 212.

[0041] In this embodiment, the first driving mechanism provides power, and the first transmission mechanism transmits power to the first rotating shaft 211, and then the first rotating shaft 211 drives the first rotating body 212 to swing. The first driving mechanism, the first transmission mechanism, the first rotating shaft 211 and the first rotating body 212 work together to make the steering process more accurate and stable, avoiding excessive swing or displacement caused by improper adjustment. This can effectively reduce safety hazards during operation and prevent the electric wrench 30 from accidentally injuring operators or causing damage to equipment.

[0042] Furthermore, the first transmission mechanism includes a first worm wheel and a first worm that mesh with each other. The first worm wheel is mounted on the first rotating shaft 211. The first driving mechanism drives the first worm to move. The first worm drives the first worm wheel to rotate, so that the first rotating shaft 211 and the first rotating body 212 move.

[0043] In this embodiment, the worm gear transmission has high transmission accuracy and can provide stable and precise movement under low speed and high load conditions. In addition, the worm gear transmission has a self-locking function. In the absence of external force, the worm wheel will not rotate in the opposite direction, which can prevent the device from moving in the opposite direction or accidentally loosening when not in operation, thereby ensuring the stability of the tightening process. The worm gear can accurately control the rotation speed and angle, so the operator can make fewer manual adjustments or fine-tuning, reducing the time wasted due to frequent manual adjustments, thereby improving the work efficiency.

[0044] Furthermore, the second steering mechanism 22 includes a second driving mechanism, a second transmission mechanism, a second rotating shaft 221 and a second rotating body 222. The second driving mechanism is fixedly installed on the first rotating body 212. The second rotating shaft 221 is rotatably installed on the first rotating body 212. The second driving mechanism drives the second rotating shaft 221 to swing through the second transmission mechanism. The second rotating body 222 is connected to the second rotating shaft 221. The second rotating shaft 221 drives the second rotating body 222 to swing. The electric wrench 30 is installed on the second rotating body 222.

[0045] In this embodiment, the second steering mechanism 22 can adjust the angle in a narrow space or complex environment, adjust the posture of the electric wrench 30 at multiple angles and directions, and adapt to bolts in different positions. The second steering mechanism 22 can accurately control the angle of the electric wrench 30 through the cooperation of the second rotating shaft 221 and the second rotating body 222, so that the electric wrench 30 can accurately align with the target bolt. In the process of bolt tightening, uneven tightening or incomplete tightening caused by angle deviation can be avoided.

[0046] Furthermore, the second transmission mechanism includes a second worm wheel and a second worm that mesh with each other. The second worm wheel is sleeved on the second rotating shaft 221. The second driving mechanism drives the second worm to move, and the second worm drives the second worm wheel to rotate, so that the second rotating shaft 221 and the electric wrench 30 move.

[0047] In this embodiment, the worm gear transmission has high transmission accuracy and can provide stable and precise movement under low speed and high load conditions. In addition, the worm gear transmission has a self-locking function. In the absence of external force, the worm wheel will not rotate in the opposite direction, which can prevent the device from moving in the opposite direction or accidentally loosening when not in operation, thereby ensuring the stability of the tightening process. The worm gear can accurately control the rotation speed and angle, so the operator can make fewer manual adjustments or fine-tuning, reducing the time wasted due to frequent manual adjustments, thereby improving the work efficiency.

[0048] Specifically, the visual bolt tightening device also includes a first limit module and a second limit module. The first limit module is fixedly installed on the base 10, and the first limit module and the first swivel 212 stop cooperate to limit the rotation range of the first swivel 212. The second limit module is fixedly installed on the first swivel 212, and the second limit module and the second swivel 222 stop cooperate to limit the rotation range of the second swivel 222.

[0049] In this embodiment, the setting of the limit module can ensure that the first rotating body 212 and the second rotating body 222 will not exceed the set rotation range during operation. The stopper cooperation of the first limit module and the second limit module limits the freedom of rotation of the first rotating body 212 and the second rotating body 222, thereby avoiding excessive rotation or loss of control. In addition, the damage to the device caused by excessive rotation is reduced, the internal structure of the device is protected from damage, and the safety of operation is improved.

[0050] The above is only an optional embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being only exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0053] In the description of this scheme, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing this scheme and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the scope of protection of this scheme; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this scheme.
