Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0059] To better understand the technical solution of this application, the following is in conjunction with the appendix. Figures 1 to 8 The fastening device according to the embodiments of this application will be described in detail.

[0060] This application provides a tightening mechanism 10. Specifically, please refer to... Figure 1The tightening mechanism 10 includes a clamping device 100, a first driving device 200, and a second driving device 300. The clamping device 100 includes a clamping assembly 110 and a bearing assembly 120 disposed opposite each other along a first direction X. The clamping assembly 110 clamps a first fastener 20, and the bearing assembly 120 carries a second fastener 30. The first driving device 200 is connected to the clamping assembly 110 and drives the clamping assembly 110 to move toward or away from the bearing assembly 120 along the first direction X. The second driving device 300 is connected to the bearing assembly 120 and drives the bearing assembly 120 to rotate relative to the clamping assembly 110, thereby tightening the first fastener 20 and the second fastener 30 onto the part to be installed. The rotation axis of the bearing assembly 120 extends along the first direction X.

[0061] It should be noted that the tightening mechanism 10 in this application embodiment can be applied to photovoltaic brackets, for example, using components on the photovoltaic bracket and photovoltaic modules as the parts to be installed, to realize the connection and installation between the photovoltaic bracket and the photovoltaic modules. It can also be used for tightening the purlin bracket and the bracket beam in the photovoltaic bracket, or for tightening the bracket beam and the purlin, etc. The use of the tightening mechanism 10 is not limited to the field of photovoltaic equipment, and can also be applied to other equipment that needs to be fastened. This application does not impose any restrictions on this.

[0062] Here, the first direction X can be understood as the preset working axis direction.

[0063] In a specific implementation, the clamping device 100 may include a clamping assembly 110 and a bearing assembly 120, which are arranged opposite to each other along a first direction X. The clamping assembly 110 is used to clamp the first fastener 20 to ensure that it will not loosen or shift during subsequent tightening. Optionally, the first fastener 20 may include a bolt, screw, bolt with washer, or screw with washer, etc., and the clamping assembly 110 may include jaws, clamping blocks, etc., to prevent the first fastener 20 from loosening or shifting through clamping force.

[0064] The support assembly 120 supports the second fastener 30, providing a support platform for the tightening of the first fastener 20 and the second fastener 30. Optionally, the second fastener 30 may include a nut that matches the bolt, and may also include a flat washer, spring washer, or other structures that match the nut. The support assembly 120 may be a rotating platform, and may include a support groove, an adjustable chuck with clamping arms, or other structures to ensure that the second fastener 30 does not fall off or shift during tightening. The rotation axis of the support assembly 120 extends along the first direction X, providing rotational freedom for the tightening operation between the first fastener 20 and the second fastener 30.

[0065] The tightening mechanism 10 may further include a first driving device 200, which is connected to the clamping assembly 110. The first driving device 200 drives the clamping assembly 110 to move along the first direction X toward or away from the bearing assembly 120, thereby reducing or increasing the distance between the clamping assembly 110 and the bearing assembly 120. This facilitates the installation and tightening of the first fastener 20 and the second fastener 30. Furthermore, it facilitates removing the tightening mechanism 10 from the installation area of ​​the component to be installed after the tightening operation is completed. For example, the first driving device 200 may employ an electric lifting device, a pneumatic lifting device, a hydraulic lifting device, or the like.

[0066] Furthermore, to achieve the rotational tightening action of the second fastener 30, a second drive device 300 is disposed on the support assembly 120. The second drive device 300 can drive the support assembly 120 to rotate relative to the clamping assembly 110, so that the second fastener 30 can rotate around the rotation axis of the support assembly 120 under the drive of the support assembly 120, thereby tightly engaging with the first fastener 20 and achieving an efficient tightening effect. Optionally, the second drive device 300 may include a servo motor, stepper motor, or other structures to drive the support assembly 120 to rotate relative to the clamping assembly 110.

[0067] In practice, a first fastener 20 can be installed on the clamping assembly 110, and a second fastener 30 can be installed on the carrying assembly 120. Then, the tightening mechanism 10 is adjusted to the predetermined installation point of the part to be installed. At this time, the clamping assembly 110 and the carrying assembly 120 can be located on opposite sides of the part to be installed. The first drive device 200 is activated to move the clamping assembly 110 toward the carrying assembly 120, so that at least a portion of the first fastener 20 passes through the second fastener 30. Simultaneously, the second drive device 300 is activated to drive the carrying assembly 120 to rotate relative to the clamping assembly 110, thereby causing the second fastener 30 to rotate into the first fastener 20, thus completing the installation and tightening operation between the first fastener 20 and the second fastener 30. This configuration achieves automated installation and tightening of fasteners, thereby improving production efficiency.

[0068] In some embodiments, please refer to Figure 1 At least one of the first driving device 200 and the second driving device 300 is disposed on one side of the clamping device 100 along the second direction Y, which intersects the first direction X. The second direction Y can be understood as a direction that intersects with or is perpendicular to the first direction X (e.g., the workpiece tightening direction).

[0069] By arranging the first driving device 200 and the second driving device 300 to the side of the clamping device 100, the structural dimensions in the tightening direction are greatly reduced, making it suitable for tightening operations in narrow spaces.

[0070] Please refer to the following: Figure 1 and Figure 2 To further illustrate this, we will take the photovoltaic module 40 and the photovoltaic bracket as examples of the components to be installed.

[0071] The photovoltaic module 40 is used to collect solar energy and can also convert solar energy into electrical energy. In one example, the photovoltaic module 40 may include a single photovoltaic panel 41; in another example, the photovoltaic module 40 may include multiple photovoltaic panels 41, which are connected by a photovoltaic support to form a photovoltaic array. The photovoltaic support includes multiple connecting beams 50, and the photovoltaic panels 41 are connected to the connecting beams 50 through a frame structure 42 at their edges. The components to be installed here are the frame structure 42 and the connecting beams 50.

[0072] Taking an exemplary structure of the connecting beam 50 as an example, the connecting beam 50 is a C-shaped beam, and the interface of the frame structure 42 of the photovoltaic panel 41 is also C-shaped; the photovoltaic panel 41 is placed on the connecting beam 50, so that the frame structure 42 contacts the connecting beam 50, and a connection hole is provided at the intersection of the frame structure 42 and the connecting beam 50. The tightening mechanism 10 is used to assemble and fix the photovoltaic panel 41 and the photovoltaic bracket by passing fasteners through the connection holes of the connecting beam 50 and the frame structure 42.

[0073] It should be noted that when connecting the connecting beam 50 and the frame structure 42 with fasteners, some fasteners (such as bolt assemblies) need to be inserted into the C-shaped opening of the frame structure 42, and other fasteners (such as nut assemblies) need to be inserted into the C-shaped opening of the connecting beam 50, and then the fasteners are tightened. The operating space is limited, especially the operating space along the first direction X, which is not easy to operate. Therefore, in related solutions, the fasteners are usually installed and tightened manually, resulting in low production efficiency and inability to cooperate with automated production.

[0074] Based on this, in a specific implementation, the tightening mechanism provided in this application can have the first driving device 200 positioned on one side of the clamping device 100 along the second direction Y, or the second driving device 300 positioned on one side of the clamping device 100 along the second direction Y, or both the first driving device 200 and the second driving device 300 positioned on one side of the clamping device 100 along the second direction Y. This arrangement reduces the space occupied by the entire tightening mechanism 10 in the first direction X, making the tightening mechanism 10 suitable for space-constrained working environments. Furthermore, by positioning at least one of the first driving device 200 and the second driving device 300 on one side of the clamping device 100 along the second direction Y, the overall structural layout of the tightening mechanism 10 can be optimized.

[0075] Furthermore, taking a photovoltaic bracket as an example, at least one of the first driving device 200 and the second driving device 300 is arranged along the second direction Y with the clamping device 100, which makes it easier for the clamping device 100 to extend into the narrow space at the connection position for tightening operation. In other words, this arrangement can improve the ease of operation of the tightening mechanism 10 and improve work efficiency.

[0076] Specifically, when connecting the frame structure 42 and the connecting beam 50 using the tightening mechanism provided in this application, the clamping component 110 is inserted into the C-shaped opening of the frame structure 42, and the bearing component 120 is inserted into the C-shaped opening of the connecting beam 50, so that the clamping component 110 and the bearing component 120 are located on both sides of the connection position of the connecting beam 50 and the frame structure 42 along the first direction X, and then the fastener is inserted and tightened by the tightening mechanism.

[0077] In some embodiments, please refer to Figure 1 and Figure 2 The tightening mechanism 10 includes a mounting platform 400, and the bearing assembly 120 is disposed on the mounting platform 400. The first driving device 200 includes a lifting mechanism 210 and a lifting platform 220. The lifting mechanism 210 is disposed on the mounting platform 400 and located on one side of the bearing assembly 120 along the second direction Y. The lifting platform 220 is connected to the lifting mechanism 210 and extends a predetermined distance relative to the lifting mechanism 210 along the second direction Y. The clamping assembly 110 is disposed above the bearing assembly 120 via the lifting platform 220.

[0078] In a specific implementation, the first driving device 200 may include a lifting mechanism 210 and a lifting platform 220. The lifting mechanism 210 is mounted on the mounting platform 400 and located on one side of the bearing assembly 120 along the second direction Y. The lifting mechanism 210 may include a fixed end and an output end. The fixed end of the lifting mechanism 210 can be connected to the mounting platform 400, and the output end of the lifting mechanism 210 can be connected to the lifting platform 220. When the first driving device 200 is activated, the lifting platform 220 rises or falls along the first direction X via the output end of the lifting mechanism 210, causing the lifting mechanism 210 to rise or fall along the first direction X as well. The movement of the lifting platform 220 in the first direction X can drive the clamping assembly 110 to move in the first direction X, thereby adjusting the distance between the clamping assembly 110 and the bearing assembly 120. This allows the clamping assembly 110 to flexibly adjust its height to accommodate different sizes of parts to be installed or the requirements of tightening positions.

[0079] It should be noted that the lifting platform 220 can adopt an arm-shaped structure extending along the second direction Y, or the clamping assembly 110 and the lifting platform 220 can extend through an arm-shaped structure extending along the second direction Y. This facilitates the clamping assembly 110 to extend into narrow installation spaces and improves the adaptability of the tightening mechanism 10.

[0080] Optionally, the lifting mechanism 210 may include one of the following mechanisms: pneumatic lifting mechanism, hydraulic lifting mechanism, electric push rod lifting mechanism, screw lifting mechanism, etc.

[0081] In some embodiments, please refer to Figure 3 The clamping device 100 also includes a first limiting structure 130, which is connected to one of the mounting platform 400 and the lifting platform 220 and can abut against the other in the first direction X to limit the extreme position of the lifting platform 220 in the first direction X.

[0082] A first limiting structure 130 is provided on one of the mounting platform 400 and the lifting platform 220, and the other is used to form an effective abutment with the first limiting structure 130 along the first direction X. The abutment between the two can limit the movement range of the lifting platform 220 in the first direction X, ensuring that the lifting platform 220 can stop smoothly and safely when it reaches its movement limit, thereby avoiding potential damage or safety hazards caused by excessive movement.

[0083] Optionally, the first limiting structure 130 may include a limiting block, which can limit the extreme position of the movement of the lifting platform 220 by setting the limiting block on one of the mounting platform 400 and the lifting platform 220 and abutting against the other in the first direction X.

[0084] In some embodiments, please refer to Figure 1The second driving device 300 includes a drive motor 310 and a transmission component 320. The transmission component 320 is connected between the drive motor 310 and the clamping assembly 110 along the second direction Y and is in transmission cooperation with the bearing assembly 120. The drive motor 310 is used to drive the transmission component 320 to move so as to drive the bearing assembly 120 to rotate.

[0085] In this embodiment, the drive motor 310 is positioned on the side of the support assembly 120 via a transmission component. This design facilitates the insertion of the support assembly 120 into narrow installation spaces, improving the adaptability of the tightening mechanism 10. The drive motor 310 can be understood as the power source of the second drive device 300. It provides stable driving force and can adjust its speed and direction according to control commands to meet the usage requirements of the second drive device 300 under different operating conditions. The transmission component 320 is used for transmission cooperation with the support assembly 120. When the drive motor 310 is started, the transmission component 320 moves under the driving force of the drive motor 310. The transmission component 320, through its own movement, drives the support assembly 120 to rotate relative to the clamping assembly 110, facilitating the tightening operation of the second fastener 30 by the support assembly 120.

[0086] In some embodiments, the transmission component 320 may adopt a structure such as a transmission chain, transmission belt, or transmission gear.

[0087] For example, the transmission component 320 may include a transmission chain, which has the characteristics of compact structure, high transmission efficiency and strong load-bearing capacity. The transmission chain ensures the continuity and stability of power transmission through the meshing and rolling of the chain links, thereby driving the load-bearing component 120 to rotate smoothly under the drive of the drive motor 310.

[0088] The transmission component 320 may also include a transmission belt, which is characterized by flexibility, wear resistance, and smooth transmission. The transmission belt utilizes the friction between the belt body and the pulley to transmit the rotational motion of the drive motor 310 to the load-bearing assembly 120, thereby achieving the rotation of the load-bearing assembly 120. Furthermore, the transmission component 320 may also include a transmission gear, which can transmit the power of the drive motor 310 to the load-bearing assembly 120 through its rotational motion around its axis, thus achieving the rotation of the load-bearing assembly 120.

[0089] In some embodiments, please refer to Figures 4 to 6 The clamping assembly 110 includes a first clamping body 111 and a limiting assembly 112. The first clamping body 111 is provided with a first receiving groove 1111 on the side facing the bearing assembly 120. At least a portion of the first fastener 20 is received in the first receiving groove 1111. The limiting assembly 112 is movably connected to the first clamping body 111 and can block or avoid the movement path of the first fastener 20 along the first direction X away from the first receiving groove 1111.

[0090] Understandably, the first clamping body 111 is provided with a first receiving groove 1111, which provides a placement space for the first fastener 20, ensuring the stability and accuracy of the first fastener 20 during the clamping process. The shape and size of the first receiving groove 1111 can be set to match the first fastener 20, thereby improving the clamping effect of the clamping assembly 110. For example, taking the first fastener 20 as a bolt structure 22 with a washer 21, the first receiving groove 1111 can be set to accommodate the nut portion of the bolt structure 22 and the washer 21. Furthermore, the opening position and direction of the first receiving groove 1111 correspond to the bearing assembly 120, ensuring that the first fastener 20 can smoothly and stably engage with the second fastener 30 within the bearing assembly 120, thereby smoothly realizing the installation and tightening operation of the fastener.

[0091] By setting the limiting component 112, the first fastener 20 can be confined within the first receiving groove 1111, enhancing the reliability and safety of the clamping component 110 in clamping the first fastener 20. Furthermore, the limiting component 112 is movably connected to the first clamping body 111, thus possessing good flexibility and adaptability, allowing the limiting component 112 to be adjusted in position and switch functions according to actual needs. In actual use, the limiting component 112 can block or avoid the movement path of the first fastener 20 along the first direction X away from the first receiving groove 1111. That is, the limiting component 112 can not only effectively prevent the first fastener 20 from accidentally falling off when clamping it, but also move relative to the first clamping body 111 when releasing the first fastener 20, thereby allowing the first fastener 20 to disengage from the first receiving groove 1111. Therefore, by moving the limiting component 112 relative to the first clamping body 111, the limiting component 112 can switch between the release state and the clamping state, so that the clamping component 110 can easily and quickly complete the operation when clamping and releasing the first fastener 20, thereby improving production efficiency.

[0092] Optionally, the limiting component 112 may include a sliding limiting block and limiting groove structure, a spring and limiting rod structure, an electromagnetic limiting structure, etc., with the purpose of clamping and releasing the first fastener 20. This application does not impose any limitations on this.

[0093] In some embodiments, please refer to Figure 4The limiting component 112 includes a limiting member 1121 and a pushing member 1122. The limiting member 1121 has a degree of freedom of movement toward the first receiving groove 1111. In the first direction X, the pushing member 1122 protrudes from the side of the first clamping body 111 toward the carrying component 120. The pushing member 1122 has a degree of freedom of movement along the first direction X and can drive the limiting member 1121 to move relative to the first receiving groove 1111. When the clamping component 110 moves toward the carrying component 120 until the pushing member 1122 contacts the carrying component 120, the carrying component 120 pushes the pushing member 1122 to move along the second direction Y. Alternatively, the clamping component 110 moves toward the part to be installed until the pushing member 1122 contacts the part to be installed, and the part to be installed can push the pushing member 1122 to move along the second direction Y.

[0094] It should be noted that the limiting member 1121 has a certain degree of freedom of movement relative to the first receiving groove 1111, and can move toward or away from the first receiving groove 1111. This design allows the limiting member 1121 to respond quickly when necessary, so as to achieve precise control over the movement of the clamping assembly 110. When the clamping assembly 110 needs to be restricted to a specific position, the limiting member 1121 will move into the first receiving groove 1111 at an appropriate time, thereby playing a locking role. In actual use, when it is necessary to limit the first fastener 20 to the first receiving groove 1111, the limiting member 1121 can move toward the first receiving groove 1111 to the clamping state, preventing the first fastener 20 from disengaging from the first receiving groove 1111. When it is necessary to release the first fastener 20 through the first receiving groove 1111, the limiting member 1121 can move away from the first receiving groove 1111 to the release state, thereby realizing the first fastener 20 disengaging from the first receiving groove 1111.

[0095] The pusher 1122 protrudes from the side of the first clamping body 111 toward the bearing assembly 120 in the first direction X. The pusher 1122 has a degree of freedom of movement in the first direction X. That is, the pusher 1122 can move relative to the first clamping body 111 in the first direction X, so that when it is subjected to external force, it can drive the limiting member 1121 to move relative to the first receiving groove 1111.

[0096] In actual use, the first drive device 200 is activated to drive the clamping assembly 110 to move toward the carrier assembly 120. As the clamping assembly 110 gradually approaches the carrier assembly, the pusher 1122 will eventually come into contact with the carrier assembly 120 or the component to be installed. After the pusher 1122 contacts the carrier assembly 120 or the component to be installed, the carrier assembly 120 or the component to be installed will apply a thrust along the first direction X to the pusher 1122, causing the pusher 1122 to move along the first direction X. As the pusher 1122 moves, it will drive the limiting member 1121 to move along the second direction Y.

[0097] In some embodiments, please refer to Figure 4 The limiting member 1121 is provided with a guide hole 1123 through it along the first direction X, and the pushing member 1122 is provided through the guide hole 1123 along the first direction X. Along the moving direction of the limiting member 1121, at least one side surface of the pushing member 1122 is provided as an inclined surface 1124, and the limiting member 1121 abuts against the inclined surface 1124 and can move relative to the first receiving groove 1111 under the action of the inclined surface 1124.

[0098] The limiting member 1121 is provided with a guide hole 1123 through it along the first direction X. The guide hole 1123 is used to accommodate the pushing member 1122 and provide a moving path for the pushing member 1122 in the first direction X, thus ensuring a tight fit and smooth sliding between the limiting member 1121 and the pushing member 1122.

[0099] To adjust the position of the limiting member 1121, at least one surface of the pushing member 1122 is configured as an inclined surface 1124. By configuring the inclined surface 1124, the pushing member 1122 and the limiting member 1121 can form effective contact and interaction. When an external force (such as the thrust of the bearing assembly 120 or the thrust of the part to be installed) is applied to the pushing member 1122, as the pushing member 1122 moves along the first direction X, the inclined surface 1124 will apply a thrust to the limiting member 1121 to push the limiting member 1121 to move relative to the first receiving groove 1111.

[0100] In some embodiments, please refer to Figure 4 Along the moving direction of the limiting member 1121, one side surface of the pushing member 1122 is an inclined surface 1124. The limiting member 1121 is configured to avoid the moving path of the first fastener 20 under the action of the inclined surface 1124. The clamping assembly 110 also includes a first elastic member 113, which connects the first clamping body 111 and the limiting member 1121. The limiting member 1121 is configured to reset under the force of the first elastic member 113 and block the moving path of the first fastener 20.

[0101] It is understandable that, along the moving direction of the limiting member 1121, one side surface of the pushing member 1122 can be set as an inclined surface 1124. During the installation and tightening of the first fastener 20 and the second fastener 30, as the bearing assembly 120 rotates, the second fastener 30 is gradually tightened to the first fastener 20. In order to remove the first fastener 20 from the clamping assembly 110 so that the tightening mechanism 10 can tighten other installation points, the bearing assembly 120 will gradually push the pushing member 1122 to move along the first direction X, so that the inclined surface 1124 pushes the limiting member 1121 away from the first receiving groove 1111. Thus, the limiting member 1121, driven by the inclined surface 1124, avoids the moving path of the first fastener 20, so that the first fastener 20 is removed from the first receiving groove 1111 and pressed against the part to be installed, thus completing the installation and tightening of the first fastener 20 and the second fastener 30.

[0102] To enhance the reset capability of the limiting member 1121, the clamping assembly 110 may also be provided with a first elastic member 113. The first elastic member 113 connects the first clamping body 111 and the limiting member 1121, and provides a stable reset force to the limiting member 1121 through the elastic action of the first elastic member 113. When the limiting member 1121 moves to avoid the first fastener 20 under the action of the inclined surface 1124, the first elastic member 113 will be stretched or compressed, storing a certain amount of elastic potential energy. When the external force of the pushing member 1122 disappears, the first elastic member 113 will release its stored elastic potential energy, pushing the limiting member 1121 to move in the opposite direction (e.g., towards the first receiving groove 1111) to reset to its original position.

[0103] For example, the first elastic element 113 may include a spring.

[0104] The force of the first elastic member 113 can reset the limiting member 1121 and block the movement path of the first fastener 20, that is, limit the first fastener 20 in the first receiving groove 1111, prevent the first fastener 20 from leaving the first receiving groove 1111 before tightening, thereby improving the stability and reliability of the clamping assembly 110.

[0105] In some embodiments, please refer to Figure 4 Along the moving direction of the limiting member 1121, the side of the pushing member 1122 opposite to the first receiving groove 1111 is an inclined surface 1124, and the inclined surface 1124 is inclined towards the first receiving groove 1111 from the opening to the bottom of the groove. The first elastic member 113 is connected to the side of the limiting member 1121 opposite to the first receiving groove 1111, and the first elastic member 113 is in a compressed state during the process of the inclined surface 1124 driving the limiting member 1121 to move.

[0106] In specific implementation, along the moving direction of the limiting member 1121, the side of the pushing member 1122 away from the first receiving groove 1111 can be made into an inclined surface 1124, and the inclined surface 1124 gradually tilts towards the first receiving groove 1111 in the direction extending from the opening of the first receiving groove 1111 to the bottom of the groove. With this configuration, when an external driving force acts on the inclined surface 1124, the limiting member 1121 can be smoothly guided to move relative to the first receiving groove 1111, reducing the resistance during the movement of the limiting member 1121.

[0107] In addition, the first elastic element 113 can be disposed on the side opposite to the first receiving groove 1111, so that when the inclined surface 1124 is subjected to an external force and drives the limiting member 1121 to move, the first elastic element 113 can deform accordingly and be in a compressed state to store elastic potential energy. When the external force driving the inclined surface 1124 to move disappears, the first elastic element 113 can release the elastic potential energy and push the limiting member 1121 back to its original position.

[0108] It should also be noted that by arranging the limiting components 112 in this way, the space occupied along the first direction X can be reduced, thereby enabling the tightening mechanism 10 to better install the parts to be installed and improving the adaptability of the tightening mechanism 10.

[0109] In some embodiments, please refer to Figure 5 and Figure 6 Along the moving direction of the limiting member 1121, both sides of the pushing member 1122 are inclined surfaces 1124. The limiting member 1121 can avoid the moving path of the first fastener 20 under the action of the inclined surface 1124 on the side away from the first receiving groove 1111, and block the moving path of the first fastener 20 under the action of the inclined surface 1124 on the side close to the first receiving groove 1111.

[0110] It is understandable that, along the moving direction of the limiting member 1121, both sides of the pushing member 1122 can be set as inclined surfaces 1124. Please refer to [link to relevant documentation]. Figure 5 The inclined surface 1124 of the pusher 1122, which is away from the first receiving groove 1111, allows the limiting member 1121 to avoid the movement path of the first fastener 20 under its guidance. That is, during the installation and tightening of the first fastener 20 and the second fastener 30, the bearing component 120 will gradually push the pusher 1122 to move along the first direction X, so that the inclined surface 1124 pushes the limiting member 1121 away from the first receiving groove 1111. Thus, the limiting member 1121 avoids the movement path of the first fastener 20 under the action of the inclined surface 1124, thereby achieving the separation of the first fastener 20 from the first receiving groove 1111.

[0111] It should be noted that you should refer to [link / reference]. Figure 5 When the supporting component 120 or the part to be installed disengages from the contact with the pusher 1122, the pusher 1122 will move in the opposite direction along the first direction X. At this time, the inclined surface 1124 near the first receiving groove 1111 will apply a reverse thrust to the limiting member 1121, causing the limiting member 1121 to move in the opposite direction (that is, move towards the first receiving groove 1111), thereby blocking the movement path of the first fastener 20 and preventing the first fastener 20 from disengaging from the first receiving groove 1111.

[0112] In some embodiments, please refer to Figure 5 Along the direction from the opening to the bottom of the first receiving groove 1111, the inclined surfaces 1124 on both sides of the pushing member 1122 are inclined toward the first receiving groove 1111.

[0113] In a specific implementation, the inclined surface 1124 of the pushing member 1122 on the side away from the first receiving groove 1111 is set to be inclined toward the first receiving groove 1111 in the direction from the opening to the bottom of the first receiving groove 1111. Thus, when the pushing member 1122 moves along the direction from the opening to the bottom of the first receiving groove 1111, this inclined surface 1124 can gradually push the limiting member 1121 away from the first receiving groove 1111, so as to realize that the limiting member 1121 avoids the movement path of the first fastener 20.

[0114] From the opening to the bottom of the first receiving groove 1111, the inclined surface 1124 of the pushing member 1122 near the first receiving groove 1111 is inclined toward the first receiving groove 1111. Thus, when the pushing member 1122 moves along the direction from the bottom to the opening of the first receiving groove 1111, this inclined surface 1124 can gradually push the limiting member 1121 toward the first receiving groove 1111, so that the limiting member 1121 blocks the movement path of the first fastener 20.

[0115] In some embodiments, please refer to Figure 5 The clamping assembly 110 also includes a second elastic member 114, which connects the first clamping body 111 and the pusher 1122. The pusher 1122 is configured to be reset under the action of the second elastic member 114, and the pusher 1122 drives the limiting member 1121 to block the movement path of the first fastener 20 through the inclined surface 1124 of the pusher 1122 near the first receiving groove 1111.

[0116] It is understood that the clamping assembly 110 may further include a second elastic element 114, which is connected between the first clamping body 111 and the pusher 1122. With this configuration, when the pusher 1122 needs to be reset, it can be reset to its initial state under the elastic action of the second elastic element 114. This ensures that the pusher 1122 can quickly and accurately return to its predetermined position when needed, facilitating subsequent clamping or release operations.

[0117] For example, the second elastic element 114 may include a spring.

[0118] Furthermore, when the pusher 1122 is reset under the action of the second elastic member 114, its inclined surface 1124 near the first receiving groove 1111 gradually approaches and contacts the limiting member 1121 along the moving path of the pusher 1122. As the pusher 1122 is reset, this inclined surface 1124 pushes the limiting member 1121 toward the first receiving groove 1111, so that the limiting member 1121 can block the moving path of the first fastener 20, ensuring that the clamping assembly 110 can firmly clamp the first fastener 20 and prevent the first fastener 20 from falling off.

[0119] In some embodiments, please refer to Figures 4 to 6 The first clamping body 111 is provided with a first guide groove 1112 communicating with the first receiving groove 1111, and the limiting member 1121 is embedded in the first guide groove 1112 and slides in cooperation with the first guide groove 1112; the first clamping body 111 is provided with a second guide groove 1113 extending along the first direction X, and the pushing member 1122 is provided in the second guide groove 1113 and slides in cooperation with the second guide groove 1113.

[0120] The first clamping body 111 may be provided with a first guide groove 1112 that communicates with the first receiving groove 1111. The limiting member 1121 is embedded in the first guide groove 1112 and forms a sliding fit with the first guide groove 1112. This arrangement not only limits the movement range of the limiting member 1121, but also ensures its stability and accuracy during movement. Through the communication between the first guide groove 1112 and the first receiving groove 1111, the limiting member 1121 can act on the first fastener 20 to block or allow the movement of the first fastener 20.

[0121] Furthermore, a second guide groove 1113 extending along the first direction X may be provided on the first clamping body 111. The pusher 1122 is disposed within the second guide groove 1113 and forms a sliding engagement relationship with the second guide groove 1113. This arrangement can limit the movement range of the pusher 1122, and through the guiding effect of the second guide groove 1113, ensure that the pusher 1122 can move smoothly along the predetermined direction.

[0122] In some embodiments, please refer to Figure 5 In the first direction X, the first receiving groove 1111 may include a first groove segment 1111a and a second groove segment 1111b arranged sequentially toward the bearing assembly 120. The first fastener 20 is a bolt structure 22 with a washer 21 sleeved on it. The nut portion of the bolt structure 22 is placed in the first groove segment 1111a, the washer 21 is placed in the second groove segment 1111b, and the limiting member 1121 extends into the second groove segment 1111b and is located below the washer 21 to limit the first fastener 20 in the first direction X.

[0123] In practice, the first groove segment 1111a and the second groove segment 1111b can be arranged sequentially along the direction toward the bearing assembly 120. The first fastener 20 can be a bolt structure 22 with a washer 21 sleeved on it. The diameter of the washer 21 is usually larger than the diameter of the bolt structure 22. Therefore, the diameter of the second groove segment 1111b can be set to be larger than the diameter of the first groove segment 1111a. This arrangement facilitates the installation of the first fastener 20.

[0124] The first groove 1111a can be used to accommodate the nut portion of the first fastener 20, and the second groove 1111b can be used to accommodate the gasket 21. It should be noted that the limiting member 1121 is configured to extend into the second groove 1111b and be located below the gasket 21. This configuration allows the limiting member 1121 to block the movement path of the first fastener 20 in the first direction X, thereby preventing the first fastener 20 from disengaging from the first receiving groove 1111.

[0125] In some embodiments, the inner wall of the first receiving groove 1111 is further provided with a second limiting structure for restricting the first fastener 20 from rotating about the first direction X as the axis of rotation.

[0126] To prevent the first fastener 20 from rotating along with the second fastener 30 during the rotation of the bearing component 120 driving the second fastener 30, thus making it difficult to tighten the first fastener 20 and the second fastener 30, a second limiting structure can be provided on the inner wall of the first receiving groove 1111. By providing the second limiting structure, the first fastener 20 is ensured to remain stable during the tightening process, effectively limiting the first fastener 20 from rotating about the first direction X as the axis of rotation.

[0127] In a specific implementation, the second limiting structure can be configured as a protrusion or groove structure that matches the first fastener 20. For example, the second limiting structure can be a polygonal structure formed by multiple limiting edges that matches the outer ring of the nut. When the first fastener 20 is installed into the first receiving groove 1111, the limiting edges of the second limiting structure will contact the first fastener 20, thereby forming an effective rotation restriction.

[0128] In some embodiments, please refer to Figure 7 The surface of the first clamping body 111 is provided with a first inlet 1114 that communicates with the first receiving groove 1111. The first inlet 1114 is used to communicate with the feeding device of the first fastener 20.

[0129] In specific implementation, to facilitate the feeding device in providing the first fastener 20 to the first clamping body 111, the surface of the first clamping body 111 can be provided with a first inlet 1114. The first inlet 1114 can be configured to communicate with both the first receiving groove 1111 and the feeding device. This ensures that the feeding device accurately places the first fastener 20 into the first receiving groove 1111 via the first inlet 1114, improving operational convenience and efficiency. By providing the first inlet 1114, the feeding device can automatically place the first fastener 20 into the first receiving groove 1111, thereby improving the level of production automation and thus increasing production efficiency.

[0130] In some embodiments, please refer to Figure 7 The inner wall of the first receiving groove 1111 is also provided with a first fixing member 1115 to prevent the first fastener 20 from detaching from the first feed port 1114.

[0131] To enhance the securing effect of the first receiving groove 1111 on the first fastener 20 and prevent the first fastener 20 from accidentally falling off from the first inlet 1114 during movement, a first fixing member 1115 can be provided on the inner wall of the first receiving groove 1111. The first fixing member 1115 can be a magnetic adsorption member, an elastic clip, or other structures. A magnetic adsorption member can be selected, as it can effectively limit the movement range of the first fastener 20 through adsorption force. When the first fastener 20 enters the first receiving groove 1111 through the first inlet 1114, the first fixing member 1115 can fix the first fastener 20 within the first receiving groove 1111, thereby avoiding the risk of falling off due to vibration or other external forces.

[0132] In some embodiments, the number of limiting components 112 is multiple, and the multiple limiting components 112 are arranged at circumferential intervals along the first receiving groove 1111.

[0133] It is understandable that multiple limiting components 112 are spaced apart along the circumference of the first receiving groove 1111, which enhances the comprehensiveness and reliability of the limiting function of the limiting components 112, and ensures that balanced and effective support and restriction can be provided in different directions and angles.

[0134] Specifically, multiple limiting components 112 are arranged around the inner wall of the first receiving groove 1111, so that each limiting component 112 can independently play a limiting role, and limit the first fastener 20 placed in the first receiving groove 1111 in all directions, effectively preventing the first fastener 20 from falling off.

[0135] In some embodiments, please refer to Figure 8 The support component 120 includes a second clamping body 121, on which a second receiving groove 1211 is provided opposite to the first receiving groove 1111, and the second fastener 30 is at least partially received in the second receiving groove 1211.

[0136] It should be noted that, in order to place at least a portion of the second fastener 30 within the second clamping body 121, the second clamping body 121 is provided with a second receiving groove 1211. As an optional embodiment, the second fastener 30 may consist of a flat washer, a spring washer, and a nut stacked along the first direction X, and the second receiving groove 1211 is used to fit the second fastener 30. Thus, at least a portion of the second fastener 30 can be accommodated within the second receiving groove 1211, preventing the second fastener 30 from disengaging from the bearing assembly 120 during rotation.

[0137] Furthermore, by positioning the first receiving groove 1111 and the second receiving groove 1211 opposite each other, it is easy to accurately align the first fastener 20 and the second fastener 30, thereby facilitating the installation and tightening of the tightening mechanism 10 with the first fastener 20 and the second fastener 30, and thus improving production efficiency.

[0138] In some embodiments, please refer to Figure 8 The surface of the second clamping body 121 is provided with a second inlet 1212 that communicates with the second receiving groove 1211. The second inlet 1212 is used to communicate with the feeding device of the second fastener 30.

[0139] It is understandable that, in order to facilitate the feeding device of the second fastener 30 to place the second fastener 30 into the second clamping body 121, the second clamping body 121 may be provided with a second inlet 1212, and the second inlet 1212 may be configured to be connected to both the second receiving groove 1211 and the feeding device. This configuration facilitates the feeding device to accurately place the second fastener 30 into the second receiving groove 1211 through the second inlet 1212, thereby improving the convenience and efficiency of operation.

[0140] In some embodiments, please refer to Figure 8 The inner wall of the second receiving groove 1211 is also provided with a second fixing member 1213 to prevent the second fastener 30 from detaching from the second feed port 1212.

[0141] Understandably, to enhance the fixing effect of the second receiving groove 1211 on the second fastener 30 and prevent the second fastener 30 from falling off from the second inlet 1212 during movement, a second fixing member 1213 can be provided on the inner wall of the second receiving groove 1211. The second fixing member 1213 can be a magnetic adsorption member, an elastic clip, or other structures; a magnetic adsorption member is preferable, as it can effectively limit the movement range of the second fastener 30 through adsorption force. When the second fastener 30 enters the second receiving groove 1211 through the second inlet 1212, the second fixing member 1213 can fix the second fastener 30 within the second receiving groove 1211, thereby avoiding the risk of falling off due to vibration or other external forces.

[0142] Please see Figures 1 to 8 The following describes the process of installing the first fastener 20 and the second fastener 30 onto the part to be installed, using the tightening mechanism 10 in an example embodiment of this application as an example.

[0143] In practice, the first fastener 20 is fed into the first receiving groove 1111 by the feeding device, and the first fastener 20 is constrained within the first receiving groove 1111 by the first fixing member 1115 and the limiting component 112. The second fastener 30 is fed into the second receiving groove 1211, and the second fastener 30 is constrained within the second receiving groove 1211 by the second fixing member 1213. The tightening mechanism 10 is adjusted to the predetermined installation point of the part to be installed. At this time, the clamping component 110 and the bearing component 120 can be located on both sides of the part to be installed.

[0144] The first drive device 200 is activated to drive the clamping assembly 110 to move toward the carrier assembly 120, so that the first fastener passes through the mounting hole on the part to be installed. When the first fastener held by the clamping assembly 110 passes through the mounting hole and contacts the second fastener, the second drive device 300 is activated to drive the second fastener to rotate only through the carrier assembly. With the circumferential movement of the first fastener and the rotation of the second fastener, the tightening installation between the first fastener and the second fastener is realized. After the first fastener and the second fastener are installed, the first drive device 200 and the second drive device 300 stop working. During this process, as the clamping assembly 110 drives the first fastener to move toward the carrier assembly, the pusher of the limiting assembly 112 contacts the carrier assembly 120 or the part to be installed and gradually pushes the pusher 1122, so that the limiting member 1121 gradually moves away from the first fastener until the limiting disappears, so that the first fastener fits onto the part to be installed after tightening.

[0145] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
