Description

Technical Field

[0001] This application relates to, but is not limited to, the field of parts assembly, and particularly to a tightening device. Background Technology

[0002] Currently, in order to reduce labor costs and improve work efficiency during assembly operations, automatic tightening devices are often used to tighten bolts, nuts, and other materials on workpieces.

[0003] In related technologies, when a tightening device tightens a workpiece, the tightening structure has a single working position. When tightening the same workpiece at different working positions, the workpiece needs to be repeatedly adjusted and positioned. This makes the tightening process cumbersome, the operation not simple, and the work efficiency low. Utility Model Content

[0004] To address the aforementioned problems, this application provides a tightening device that simplifies the tightening process and improves work efficiency.

[0005] This application provides a tightening device, which includes a first base, a second base, and a tightening structure. The first base is used to connect to a workbench and is provided with a first guide rail. A first moving member that can slide along the first guide rail is provided on the first guide rail. The second base is connected to the first moving member and is provided with a second guide rail. A second moving member that can slide along the second guide rail is provided on the second guide rail. The tightening structure includes a tightening rod and a tightening part. The tightening rod is connected to the second moving member and is used to drive the tightening structure to move along the second guide rail. The tightening part is used to tighten the material. The first guide rail and the second guide rail have different directions.

[0006] The tightening device provided in this application has a tightening structure connected to a second moving member via a tightening rod. Since the second moving member can slide along a second guide rail, which is mounted on a second base, the tightening rod can drive the tightening structure to slide relative to the second base along the second guide rail. The second base is connected to the first moving member. Since the first moving member can slide along a first guide rail, which is mounted on the first base, the second base can slide relative to the first base along the first guide rail. The tightening structure can slide relative to the second base, and the second base can slide relative to the first base along the first guide rail. Therefore, the tightening structure can slide relative to the first base along the first guide rail. In other words, the tightening structure can slide not only relative to the second base along the second guide rail, but also... Alternatively, it can slide along the first guide rail relative to the first base, together with the second base. Since the first and second guide rails are in different directions, the tightening structure can slide in both directions. When tightening the workpiece, the tightening structure moves to the working position along the guide rail and tightens the material through the tightening part. After the material at the current working position is tightened, the position of the tightening structure can be adjusted by sliding cooperation on the first and second guide rails. The position of the tightening structure is adjusted according to the position of the next working position, so that the tightening structure moves to the next working position on the workpiece to continue the tightening operation. After the operation is completed, the tightening structure moves to the next working position again until the material at all working positions is tightened.

[0007] Compared with related technologies that require repeated adjustments and positioning of the workpiece, the tightening device provided in this application changes the position of the tightening structure relative to the workpiece by sliding the tightening structure along two guide rails in different directions. After completing the work at one position, the tightening structure can move to the next working position until the material tightening at all working positions on the workpiece is completed. In this way, the tightening operation process is simplified and the work efficiency is improved.

[0008] In one possible implementation provided in this application, a first driving member is further provided on the first base, and the output end of the first driving member is connected to the first moving member to drive the first moving member to slide along the first guide rail.

[0009] In one possible implementation provided in this application, a second driving member is connected to the second base, and the output end of the second driving member is connected to the second moving member to drive the second moving member to slide along the second guide rail.

[0010] In one possible implementation provided in this application, the second moving member is connected to the end of the screw rod near the tightening part.

[0011] In one possible implementation provided in this application, a third moving member is connected to the tightening part, the third moving member is slidably connected to the second guide rail, and moves along the second guide rail.

[0012] In one possible implementation provided in this application, a guide sleeve is provided at one end of the second base near the tightening part, and when the tightening structure tightens the material, the tightening part passes through the guide sleeve.

[0013] In one possible implementation provided in this application, the second base is further provided with a limiting part, the limiting part and the guide sleeve are respectively located at opposite ends of the second base, and the limiting part can at least abut against the second driving member along the movement direction of the second moving member.

[0014] In one possible implementation provided in this application, the tightening part includes a tightening member for tightening the material; a third driving member is provided on the tightening rod for driving the tightening member to rotate relative to the tightening rod.

[0015] In one possible implementation provided in this application, the tightening part further includes a rotary connector, which is rotatably connected to the tightening rod, and the tightening part is detachably connected to the rotary connector.

[0016] In one possible implementation provided in this application, the second moving member can move relative to the second base to a first position and a second position; when the second moving member moves to the first position, the rotating connector separates from the tightening member, and when the second moving member moves to the second position, the rotating connector and the tightening member are connected in a transmission manner.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] Currently, during assembly operations, it is often necessary to tighten the materials used for connection to ensure the stability and safety of the assembly. These materials may include bolts, nuts, threaded components, and pins. For example, in automobile production, the body of the car largely uses unibody castings. Due to the inability to weld aluminum alloys and traditional steel, and limitations in the structure and thickness of some body-in-white components, bolt connections are extensively used during assembly, requiring a large amount of bolt tightening work.

[0037] In the process of tightening materials, in order to reduce labor costs and improve work efficiency, automatic tightening devices are often used to tighten bolts, nuts and other materials on the workpiece.

[0038] In related technologies, when a tightening device tightens a workpiece, the tightening structure has a single working position. When tightening the same workpiece at different working positions, the workpiece needs to be repeatedly adjusted and positioned. This makes the tightening process cumbersome, the operation not simple, and the work efficiency low.

[0039] This application provides a tightening device, referring to... Figure 1 and Figure 2The tightening device includes a first base 1, a second base 2, and a tightening structure 3. The first base 1 is used to connect to the workbench and is provided with a first guide rail 11. A first moving part that can slide along the first guide rail 11 is provided on the first guide rail 11. The second base 2 is connected to the first moving part and is provided with a second guide rail 21. A second moving part 22 that can slide along the second guide rail 21 is provided on the second guide rail 21. The tightening structure 3 includes a tightening rod 31 and a tightening part 32. The tightening rod 31 is connected to the second moving part 22 and is used to drive the tightening structure 3 to move along the second guide rail. The tightening part 32 is used to tighten the material. The first guide rail 11 and the second guide rail 21 have different directions.

[0040] In this embodiment, the tightening structure 3 is connected to the second moving member 22 via a tightening rod 31. Since the second moving member 22 can slide along the second guide rail 21, which is located on the second base 2, the tightening rod 31 can drive the tightening structure 3 to slide relative to the second base 2 along the second guide rail 21. The second base 2 is connected to the first moving member. Since the first moving member can slide along the first guide rail 11, which is located on the first base 1, the second base 2 can slide relative to the first base 1 along the first guide rail 11. The tightening structure 3 can slide relative to the second base 2, and the second base 2 can slide relative to the first base 1 along the first guide rail 11. Therefore, the tightening structure 3 can slide relative to the first base 1 along the first guide rail 11. In other words, the tightening structure 3 can not only slide relative to the second base 2 along the second guide rail 21, but also... Together with the second base 2, it slides along the first guide rail 11 relative to the first base 1. Since the first guide rail 11 and the second guide rail 21 are in different directions, the tightening structure 3 can slide in both directions. When tightening the workpiece, the tightening structure 3 moves to the working position along the first guide rail 11 and tightens the material through the tightening part 32. After the material at the current working position is tightened, the position of the tightening structure 3 can be adjusted by sliding cooperation on the first guide rail 11 and the second guide rail 21. The position of the tightening structure 3 is adjusted according to the position of the next working position, so that the tightening structure 3 moves to the next working position on the workpiece to continue the tightening operation. After the operation is completed, the tightening structure 3 moves to the next working position by sliding cooperation on the first guide rail 11 and the second guide rail 21 until the material at all working positions is tightened.

[0041] Compared with related technologies that require repeated adjustments and positioning of the workpiece, the tightening device provided in this application changes the position of the tightening structure 3 relative to the workpiece by sliding the tightening structure 3 along the first guide rail 11 and the second guide rail 12 in different directions. After completing the work at one position, the tightening structure 3 can move to the next working position until the material tightening at all working positions on the workpiece is completed, which simplifies the tightening operation process and improves work efficiency.

[0042] In this embodiment of the application, a first guide rail 11 is provided on the first base 1. The first base 1 can be a block structure, a plate structure, or the like. The shape of one side of the first guide rail 11 can be rectangular, rhomboid, or the like. The first guide rail 11 can be a linear guide rail or a curved guide rail. For example, see [reference]. Figure 1 The first base 1 is a block structure. Since the first base 1 is used to connect with the workbench, the block structure can increase the stability of the connection. The shape of one side of the first guide rail 11 is rectangular. The first guide rail 11 is a linear guide rail, and the first moving part can slide linearly along the first guide rail 11.

[0043] In this embodiment, the second base 2 is connected to the first moving member. The connection between the second base 2 and the first moving member can be a fixed connection or a detachable connection. The second base 2 can be directly connected to the first moving member or connected to the first moving member through other structures. For example, since the first moving member can move along the first guide rail 11, the second base 2 can also move along the first guide rail 11 after being connected to the first moving member. To enhance the stability of the movement of the second moving member 22 and the tightening structure 3 on the second base 2, refer to... Figure 2 A third base 23 is connected between the second base 2 and the first moving part. The third base 23 connects the second base 2 and the first moving part to enhance the stability of the structure during movement.

[0044] In this embodiment, a second guide rail 21 is provided on the second base 2, and a second moving member 22 that can slide along the second guide rail 21 is provided on the second guide rail 21. The second base 2 can be a block structure, a plate structure, or the like. The shape of one side of the second guide rail 21 can be rectangular, rhomboid, or the like. The second guide rail 21 can be a linear guide rail or a curved guide rail. For example, see [reference needed]. Figure 2 The second base 2 is a plate-shaped structure. Since the second base 2 needs to move along the first guide rail 11, the plate-shaped structure is lighter and facilitates enhanced movement flexibility. The shape of one side of the second guide rail 21 is rectangular. The second guide rail 21 is a linear guide rail, and the second moving part 22 can slide along the second guide rail 21 in a straight line.

[0045] In this embodiment, the first guide rail 11 and the second guide rail 21 have different directions. The orientation of the first guide rail 11 and the second guide rail 21 can be set according to operational requirements, and the first guide rail 11 and the second guide rail 21 can be at any angle. For example, see [reference]. Figure 1 and Figure 2The first guide rail 11 is in the horizontal direction and the second guide rail 21 is in the vertical direction. Thus, the tightening mechanism can first adjust its position in the horizontal direction by moving on the first guide rail 11, and then move the tightening device in the horizontal direction to a position that overlaps with the working position in the vertical direction. Then, it moves on the second guide rail 21 to move closer to the working position in the vertical direction. After moving to the working position, the tightening device tightens the material through the tightening part 32.

[0046] To achieve the sliding of the first moving member along the first guide rail 11, some embodiments provided in this application refer to... Figure 1 The first base is also provided with a first driving component 12. The output end of the first driving component 12 is connected to the first moving component to drive the first moving component to slide along the first guide rail 11.

[0047] Since the output end of the first driving member 12 is connected to the first moving member, it can provide power to the first moving member and drive the first moving member to slide along the first guide rail 11. Since the second base 2 is connected to the first moving member, under the drive of the first driving member 12, the second base 2 can slide along the first guide rail 11 with the first moving member. That is, the first driving member 12 can drive the tightening structure 3 to slide relative to the first base 1 along the first guide rail 11, thereby realizing the displacement of the tightening structure 3 in the direction of the first guide rail 11.

[0048] It should be added that, depending on the shape of the first guide rail 11, different first driving members 12 can be set for different movements of the output end. The first driving member 12 can be a driving member for rotational movement of the output end, or it can be a driving member for linear movement of the output end. For example, refer to Figure 1 The first guide rail 11 is a linear guide rail. Therefore, the first driving component 12 can be a hydraulic cylinder, pneumatic cylinder, electric telescopic rod, or other driving component with linear motion at the output end. The output end of the first driving component 12 is connected to the first moving component. The fixed end of the first driving component 12 can be fixed on the first base 1 or on the worktable.

[0049] To enable the second moving member 22 to slide along the second guide rail 21, some embodiments provided in this application refer to... Figure 1 and Figure 3 A second driving member 24 is connected to the second base 2. The output end of the second driving member 24 is connected to the second moving member 22 to drive the second moving member 22 to slide along the second guide rail 21.

[0050] Since the output end of the second driving member 24 is connected to the second moving member 22, it can provide power to the second moving member 22 and drive the second moving member 22 to slide along the second guide rail 21. Since the tightening rod 31 of the tightening structure 3 is connected to the first moving member, the tightening structure 3 can slide along the second guide rail 21 with the second moving member 22 under the drive of the second driving member 24. That is, the second driving member 24 can drive the tightening structure 3 to slide relative to the second base 2 along the second guide rail 21, thereby realizing the displacement of the tightening structure 3 on the second guide rail 21.

[0051] It should be added that, depending on the shape of the second guide rail 21, a second drive member 24 with different movements at the output end can be set. The second drive member 24 can be a drive member for rotational movement at the output end, or it can be a drive member for linear movement at the output end. For example, refer to [reference needed]. Figure 1 and Figure 3 The second guide rail 21 is a linear guide rail. Therefore, the second driving component 24 can be a driving component with linear motion at the output end, such as a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod. The output end of the second driving component 24 is connected to the second moving component 22, and the fixed end of the second driving component 24 can be fixed on the second base 2.

[0052] In this embodiment of the application, the second driving member 24 may include one output terminal or multiple output terminals that move in the same direction. For example, see [reference]. Figure 3 The second driving component 24 consists of a pulling cylinder 24a and a driving cylinder 24b. The fixed end of the pulling cylinder 24a is connected to the second base 2, and the fixed end of the driving cylinder 24b is connected to the second moving component 22. The output ends of the pulling cylinder 24a and the driving cylinder 24b are connected. The output end of the pulling cylinder 24a extends and retracts to pull the driving cylinder 24b. The driving cylinder 24b drives the second moving component 22 to slide along the second guide rail 21, thereby driving the tightening structure 3 to slide along the second guide rail 21. Then, the driving cylinder 24b drives the tightening structure 3 to make relatively fine movements on the second guide rail 21 until the tightening structure 3 moves to the tightening position. The driving cylinder 24b has a shorter driving stroke and higher driving accuracy than the pulling cylinder 24a, so as to drive the tightening structure 3 to make relatively fine movements.

[0053] Since the tightening structure 3 is connected to the second moving member 22 via the tightening rod 31, and the tightening structure 3 also includes a tightening part 32, the movement of the second moving member 22 drives the tightening rod 31 to move, which in turn drives the tightening structure 3 to move. In order to make the movement of the tightening structure 3 on the second guide rail 21 more stable, in one possible embodiment of this application, the second moving member 22 is connected to the end of the tightening rod 31 near the tightening part 32.

[0054] In this embodiment, the second moving part 22 can slide along the second guide rail 21 under the drive of the second driving part 24. The second moving part 22 is connected to the screw rod 31. When the second moving part 22 slides, it can drive the screw rod 31 to slide on the second guide rail 21, thereby driving the tightening structure 3 to slide. The tightening structure 3 also includes a tightening part 32, which is used to tighten the material. That is, the movement of the screw rod 31 drives the movement of the tightening part 32.

[0055] The second moving part 22 is connected to the end of the screw rod 31 near the tightening part 32. In this way, when the screw rod 31 drives the tightening part 32 to move together, the force points of the screw rod 31 and the tightening part 32 are closer to the second moving part 22, which reduces the influence of torque on the tightening part 32. This can reduce the deformation and bending of the screw rod 31 and the tightening part 32, enhance the stability of the system, and reduce the impact of vibration on the stability of the system during the movement.

[0056] The connection between the second moving component 22 and the screw rod 31 can be adhesive, bolted, threaded, or snap-fit, etc. This application does not limit this. The second moving component 22 can be a block structure, a plate structure, a frame structure, etc. For example, see [reference]. Figure 2 The second moving part 22 has a cuboid structure and is threadedly connected to the screw rod 31.

[0057] The tightening part 32 slides along the direction of the second guide rail 21 under the drive of the tightening rod 31. The tightening part 32 is used to tighten materials. Therefore, the movement of the tightening part 32 on the second guide rail 21 needs to be sufficiently stable to ensure the efficiency and quality of the tightening operation. In order to make the sliding of the tightening part 32 along the second guide rail 21 more stable, in one possible embodiment of this application, refer to Figure 2 and Figure 3 A third moving part 25 is connected to the tightening part. The third moving part 25 is slidably connected to the second guide rail 21 and moves along the second guide rail 21.

[0058] Because the third moving part 25 is slidably connected to the second guide rail 21, it provides support and guidance for the movement of the tightening part 32 on the second guide rail 21, making the movement of the tightening part 32 along the second guide rail 21 more stable, reducing the deviation of the tightening part 32 relative to the second guide rail 21, and improving the accuracy of the tightening part 32 reaching the working position. At the same time, the slidability of the third moving part 25 relative to the second guide rail 21 saves the force consumption for the tightening rod 31 to drive the tightening part 32 to slide on the second guide rail 21, reducing the energy loss of the system and improving efficiency.

[0059] The third moving part 25 can be connected to the driving part, and the driving part drives the second moving part 22 and the third moving part 25 to slide along the second guide rail 21; the third moving part 25 can also be disconnected from the driving part. When the second driving part 24 drives the screw rod 31 to move the tightening part 32, the third moving part 25 provides support and guidance, and assists the tightening part 32 to slide along the second guide rail 21.

[0060] When the tightening part 32 slides along the second guide rail 21, the vibration generated by the sliding will cause the tightening part 32 to sway. In order to further improve the stability of the tightening part 32 when it is close to the working position and ensure the quality of the tightening operation, in one possible embodiment of this application, refer to Figure 1 and Figure 4 A guide sleeve 26 is provided on one end of the second base near the tightening part 32. When the tightening structure 3 tightens the material, the tightening part 32 passes through the guide sleeve 26.

[0061] In this embodiment, when the tightening part 32 moves along the second guide rail 21 to the working position corresponding to the workpiece, the tightening part 32 contacts the material and performs tightening operation. Since the second base 2 is provided with a guide sleeve 26 at one end near the tightening part 32, and the tightening part 32 passes through the guide sleeve 26, when the tightening part 32 moves along the second guide rail 21, the guide sleeve 26 can provide guidance for the tightening part 32. When the tightening part 32 performs tightening operation, the tightening part 32 needs to rotate, and the guide sleeve 26 can provide a limiting function for the tightening part 32.

[0062] It should be added that, for reference Figure 2 and Figure 3 A fourth base 28 can be provided between the guide sleeve 26 and the second base 2. The fourth base 28 is used to connect the guide sleeve 26 to the second base 2 and to provide support and fixation for the guide sleeve 26. The fourth base 28 is provided with a through hole. The position of the through hole corresponds to the extension direction of the tightening part 32. A guide space is formed between the through hole and the guide sleeve 26 to allow the tightening part 32 to pass through. The tightening part 32 can pass through the guide space and out of the guide sleeve 26.

[0063] In this embodiment, the tightening part 32 can contact the material after passing through the guide sleeve 26, or it can contact the material before passing through the guide sleeve 26, and then pass through the guide sleeve 26 together with the material. To avoid the material falling out, for example, refer to... Figure 1 and Figure 3In this embodiment, the guide sleeve 26 is connected to the discharge port 4 of the feeding mechanism. The discharge port A is connected to and communicates with the guide sleeve 26. The material is fed out from the discharge port 4 of the feeding mechanism and enters the guide space inside the guide sleeve 26. After the tightening structure 3 enters the guide space through movement, it comes into contact with the material. As the tightening part 32 continues to move, the tightening part 32 carries the material out from inside the guide sleeve 26 and reaches the working position of the workpiece to complete the material tightening operation. This is the working state of the tightening structure 3.

[0064] It should be added that, in order to limit the working state of the tightening structure 3 and prevent the tightening part 32 from extending too far out of the guide sleeve 26, causing collisions between the tightening part 32 and the workpiece, resulting in wear of the tightening part 32 or the workpiece, a mutually cooperating limiting structure can be set on the tightening part 32 and the guide sleeve 26 to limit the length of the tightening part 32 extending out of the guide sleeve 26. This can be adjusted according to the needs of the tightening operation to avoid damage to the system and the workpiece.

[0065] Therefore, to prevent material inside the guide sleeve 26 from falling out before the tightening part 32 reaches it, a limiting structure can be provided on the guide sleeve 26. This structure can restrict the material from falling out before the tightening part 32 passes through the guide sleeve 26. For example, see [reference needed]. Figure 1 and Figure 3 The guide sleeve has a limiting part 261 at the protruding end of the tightening part 32. When the tightening part 32 does not protrude from the guide sleeve 26, the limiting part 261 is closed. The material is fed into the guide sleeve 26 from the discharge port 4. The closed limiting part 261 can prevent the material from falling out of the guide sleeve 26. When the tightening part 32 contacts the material in the guide sleeve 26 and protrudes from the guide sleeve 26, the limiting part 261 opens, allowing the tightening part 32 to carry the material out of the guide sleeve 26 and reach the working position of the workpiece to complete the tightening work.

[0066] Furthermore, in order to improve the quality and efficiency of the tightening part 32 in tightening the material, and to avoid the tightening part 32 working ineffectively without contacting the material, for example, refer to Figure 1 and Figure 3 A sensor 41 is also provided on the discharge port 4 to sense the discharge status at the discharge port 4. When material is sent out from the discharge port 4, the sensor detects it and the system controls the tightening structure 3 to move. The tightening part 32 enters the guide sleeve 26 to contact the material, thereby enhancing the system's working efficiency and improving the work quality.

[0067] After the tightening structure 3 completes the tightening operation, it will slide along the second guide rail 21 in the opposite direction to the guide sleeve 26. In one possible embodiment of this application, refer to Figure 2 and Figure 3The second base is also provided with a limiting part 27. The limiting part 27 and the guide sleeve 26 are located at opposite ends of the second base 2. The limiting part 27 can at least abut against the second driving member 24 along the movement direction of the second moving member 22.

[0068] In this embodiment of the application, the limiting part 27 can at least abut against the second driving member 24 along the movement direction of the second moving member 22. Here, the movement direction of the second moving member 22 is the movement of the second moving member 22 away from the guide sleeve 26. When the second moving member 22 moves away from the guide sleeve 26, the limiting part 27 can abut against the second driving member 24. At this time, the movement of the second moving member 22 stops.

[0069] In this embodiment, the limiting part 27 and the guide sleeve 26 are located at opposite ends of the second base 2. When the tightening structure 3 needs to tighten, it slides along the second guide rail 21 toward one end of the guide sleeve 26 until the tightening part 32 passes through the guide sleeve 26 to tighten. After the tightening work at the current working position is completed, the tightening structure 3 slides along the second guide rail 21 toward the end where the limiting part 27 is located until the second driving member 24 abuts against the limiting part 27. The tightening structure 3 stops sliding, and the limiting part 27 abuts against the second driving member 24 along the movement direction of the second moving member 22. This can limit the maximum distance that the second moving member 22 drives the tightening structure 3 to slide along the second guide rail 21, preventing the second moving member 22 and the tightening structure 3 from sliding outside the second guide rail 21 and causing system failures or other problems.

[0070] In one possible embodiment of this application, the tightening part 32 includes a tightening member 321 for tightening materials; a third driving member is provided on the tightening rod 31 for driving the tightening member 321 to rotate relative to the tightening rod 31.

[0071] In this embodiment, a third driving member is provided on the screw rod 31. The third driving member is used to drive the tightening member 321 to rotate relative to the screw rod 31. The third driving member can be an electric driving member, a pneumatic driving member, or a hydraulic driving member. For example, an electric motor can be integrated in the screw rod 31 to provide the tightening member 321 with high torque and power for precise control relative to the screw rod 31. It should be added that the end of the screw rod 31 away from the tightening member 321 has a wiring port 311 for electrically connecting the third driving member.

[0072] When the tightening member 321 contacts the material and is in the working position of the workpiece, the third driving member works to provide the tightening member 321 with the torque to tighten the material. The tightening member 321 rotates, driving the material to complete the tightening operation.

[0073] In this embodiment, the tightening component 321 is used to tighten materials, such as bolts, nuts, screws, etc. There can be multiple tightening components 321. Depending on the material being tightened, different shapes of tightening components 321 can be replaced, so that the tightening structure 3 can adapt to more usage scenarios and improve the adaptability of the device. At the same time, it is convenient and simple to operate, as only different shapes of tightening components 321 need to be replaced.

[0074] The tightening component 321 can be directly connected to the third driving component of the tightening rod 31. When the tightening component 321 needs to be replaced according to different materials, compared to connecting the tightening component 321 to the third driving component through other structures, the replacement of the tightening component 321 is more convenient. In one possible embodiment of this application, refer to... Figure 1 and Figure 4 The tightening part 32 also includes a rotating connector 322, which is rotatably connected to the tightening rod 31, and the tightening part 321 is detachably connected to the rotating connector 322.

[0075] Since the rotating connector 322 is rotatably connected to the screw rod 31, that is, the rotating connector 322 is connected to the third drive component inside the screw rod 31, it can rotate relative to the screw rod 31. When the tightening component 321 is connected to the rotating connector 322, the rotating connector 322 can drive the tightening component 321 to rotate, thus completing the tightening work. When the tightening component 321 is disassembled relative to the rotating connector 322, the tightening component 321 can be replaced to match different materials. Damaged tightening components 321 can also be repaired and replaced individually. The operation is simple.

[0076] It should be added that the connection between the rotary connector 322 and the tightening member 321 can be a snap-fit ​​connection, a magnetic connection, or a threaded connection. For comparison, to enhance the connection structure between the rotary connector 322 and the tightening member 321, see the example below. Figure 1 and Figure 4 A coupling mechanism 3211 is provided in the area where the rotary connector 322 and the tightening member 321 are connected. The coupling mechanism 3211 is used to realize the detachable connection between the rotary connector 322 and the tightening member 321, and at the same time transmit power between the two to ensure that the tightening member 321 can rotate under the drive of the rotary tightening member 321. The coupling mechanism 3211 can be a gear coupling, a coupling, a key connection, a pin connection, a magnetic connection, a vacuum connection, etc., and this application does not limit it.

[0077] The coupling mechanism 3211 can be disposed on the tightening member 321 or on the rotating connector 322. In comparison, in the embodiment of this application, the coupling mechanism 3211 is disposed at the end of the tightening member 321 close to the rotating connector 322, and the coupling mechanism 3211 is connected to the third moving member 25. When the tightening member 321 and the rotating connector 322 are in a disassembled state, that is, when the tightening member 321 is separated from the tightening rod 31, the third moving member 25 is connected to the coupling mechanism 3211, which can provide support and fixation for the tightening member 321 on the second guide rail 21, preventing the tightening member 321 from falling off the device.

[0078] The third moving part 25 is connected to the coupling mechanism 3211. When the tightening part 321 and the rotating connecting part 322 are connected and the tightening part 321 and the rotating connecting part 322 are in a high-speed rotating state, the connection point of the tightening part 321 and the rotating connecting part 322 is connected to the third moving part 25 through the coupling mechanism 3211 and connected to the second guide rail 21. This can provide a certain support force for the tightening part 321 and the rotating connecting part 322, and avoid deformation and separation of the tightening part 321 and the rotating connecting part 322 during the rotation process.

[0079] In one possible embodiment of this application, the second moving member 22 can move relative to the second base 2 to a first position and a second position; when the second moving member 22 moves to the first position, the rotating connector 322 is separated from the tightening member 321, and when the second moving member 22 moves to the second position, the rotating connector 322 is connected to the tightening member 321 in a transmission connection.

[0080] In this embodiment, when the second moving member 22 moves to the first position relative to the second base 2, the rotating connector 322 separates from the tightening member 321, the rotating connector 322 does not generate a rotational driving force on the tightening member 321, and the tightening member 321 stops rotating. At this time, the tightening structure 3 is in a non-working state. When the second moving member 22 moves to the second position relative to the second base 2, the rotating connector 322 and the tightening member 321 are connected by transmission. The rotating connector 322 transmits rotational power to the tightening member 321, driving the tightening member 321 to rotate at high speed. At this time, the tightening structure 3 is in a working state.

[0081] Since the tightening component 321 and the rotating connector 322 are in a state of high-speed rotation during the tightening operation, after one tightening operation is completed, the tightening component 321 needs to contact the material again and bring the material to the working position. In order to avoid the material flying out or colliding when the high-speed rotating tightening component 321 contacts the material, the tightening component 321 and the rotating connector 322 are separated after one tightening operation is completed. After separation, the tightening component 321 has no power to continue high-speed rotation, and it is safer to contact the material again. After contacting the material, the rotating connector 322 connects to the tightening component 321, driving the tightening component 321 to rotate at high speed to complete the next tightening operation.

[0082] In the embodiments of this application, a counter 29 is also provided in the area where the tightening structure 3 is located. The counter 29 can be set on the coupling mechanism 3211, the tightening rod 31, or the guide sleeve 26. For example, see [reference]. Figure 1 and Figure 4 The counter 29 is set on the second base 2 and is connected to the coupling mechanism 3211. When the tightening part 321 and the rotating connecting part 322 complete one connection and separation, the counter 29 counts once. In this way, the number of tightening operations completed by the tightening structure 3 can be recorded, which is convenient for operators to count and check.

[0083] Based on the embodiments provided in this application, by way of example, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The first base 1 is connected to the worktable. When the sensor 41 senses that the material is being discharged from the outlet 4, the first driving member 12 drives the first moving member to slide along the first guide rail 11, which in turn drives the second base 2 to slide along the first guide rail 11, thus enabling the tightening structure 3 to slide in two different directions. The material slides to the work position where it is to be tightened, and then the second driving member 24 drives the second moving member 22 to slide along the second guide rail 21, which in turn drives the tightening structure 3 to slide along the second guide rail 21. Under the drive of the second driving member 24, the tightening rod 31 slides along the second guide rail 21 towards the end where the tightening part 32 is located. As the tightening rod 31 moves, the third driving member drives the rotating connecting member 322 to rotate at a low speed. When the rotating connecting member 322 contacts the tightening member 321, the coupling mechanism 3211 connects the rotating connecting member 322 and the tightening member 321. The tightening structure 3 continues to move under the influence of the second driving member 24. Driven by the first drive, the screw 32 slides along the second guide rail 21 toward the end where the tightening part 32 is located. When the other end of the tightening part 321 contacts the material, it drives the material to pass through the guide sleeve 26 and reach the working position of the workpiece. The third drive drives the rotating connector 322 and the tightening part 32 to rotate at high speed to tighten the material. After tightening is completed, the second drive drives the tightening structure 3 to slide along the second guide rail 21 toward the end where the tightening rod 31 is located. At this time, the tightening part 32 exits the guide sleeve 26. As the tightening structure 3 slides, the tightening part 321 and the rotating connector 322 separate. The counter 29 counts. The tightening structure 3 then moves until the second drive 24 abuts against the limiting part 27 and stops moving. The first drive drives the second base 2 to move to the next working position. The above movement is repeated until the next tightening operation is completed. This cycle continues until the tightening operation of all working positions on the workpiece is completed.

[0084] Based on the embodiments provided in this application, by way of example, refer to Figure 6 and Figure 7 The tightening device may also include an automatic turntable 5, a clamping positioning structure 6, a control structure 7, a storage box 8, a feeding and sorting structure 9, and a feeding pipe A. The automatic turntable 5 drives the tightening device to rotate in different directions to adapt to different working environments. The clamping positioning structure 6 positions the workpiece and clamps and fixes it on the worktable. The control structure 7 is used to control the feeding structure, drive components, and other structures to complete their corresponding work. The control structure 7 may include components such as a valve island and an electrical control signal board. The storage box 8 is used to store materials. The storage box 8 can be connected to the worktable through a mounting base. The feeding and sorting structure 9 is used to sort and organize the materials in the storage box 8. The sorted materials are then fed to the outlet 4 through the feeding pipe A, which is connected to the feeding and sorting structure 9.

[0085] The tightening structure 3 is connected to the worktable, corresponding to the position where the workpiece is clamped. The tightening structure 3 can be set in any number or in different directions to accommodate different tightening requirements for workpieces of different shapes. For example, refer to... Figure 8 , Figure 9 , Figure 10 and Figure 11 The tightening structure 3 is configured as four, of which two tightening structures 3 are arranged vertically with the tightening part 32 of the tightening structure 3 facing the workpiece side, and the other two tightening structures 3 are arranged horizontally on both sides of the workpiece, with one end of the tightening part 32 of the tightening structure 3 facing the workpiece side.

[0086] The distribution of the tightening components 3 on the worktable can be adjusted according to the shape of the workpiece. For example, refer to... Figure 8 , Figure 9 , Figure 10 and Figure 11 In order to more comprehensively tighten the working positions on both sides of the workpiece, a tightening structure 3 set in a vertical direction and a tightening structure 3 set in a horizontal direction are arranged in one group, and the other two are arranged in another group. The two groups of tightening structures 3 are symmetrically distributed along the central axis of the tightening device.

[0087] Furthermore, the number of storage boxes 8 and feeding sorting structures 9 can be arbitrary, and can be increased or decreased according to the number of tightening structures 3. When there are many tightening structures 3, the number of storage boxes 8 and feeding sorting structures 9 can be increased to improve the efficiency of feeding all tightening structures 3. When there are few tightening structures 3, the number of storage boxes 8 and feeding sorting structures 9 can be appropriately reduced to save costs and reduce losses. For example, there are two storage boxes 8 and two feeding sorting structures 9, which are distributed on both sides of the tightening device to feed two sets of tightening structures 3 symmetrically distributed along the central axis of the tightening device.

[0088] Feeding pipe A is used to connect the discharge port 4 and the feeding sorting structure 9. The number of feeding pipes A can be adjusted according to the number of feeding sorting structures 9 and tightening structures 3. The length of feeding pipe A can be adjusted according to the distance between the discharge port 4 on the feeding sorting structure 9 and the tightening structure 3. This application does not limit this.

[0089] The embodiments provided in this application not only simplify the tightening process and improve work efficiency, but also address tightening situations where the operating space is small and the operation is inconvenient. After the workpiece is clamped and fixed by the clamping positioning structure 6, the tightening structure 3 can be moved to a relatively small area by sliding on the guide rail to complete the tightening operation.

[0090] The above description is merely an embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be covered within the scope of protection of this application.
