[0010] Beneficial effects

[0011] This invention provides a quickly switchable hydraulic clamping mechanism. Compared with the prior art, it has the following advantages:

[0012] With the vertical movement unit, the first air pump drives the first moving frame to move vertically via an air pipe. The flexible guide rail on the first mounting plate is connected to the second mounting frame, providing precise guidance for vertical movement and ensuring that the first moving frame drives the horizontal movement unit to move smoothly, reducing movement deviation and improving the stability of vertical movement. At the same time, the first telescopic cloth extends and retracts with the vertical movement of the first moving frame, effectively preventing dust, debris, etc. from entering the mechanism, protecting the internal parts and extending the service life of the mechanism. With the horizontal movement unit, the second air pump in the fixed box drives the second moving frame to move horizontally via an air rod. A pair of second telescopic cloths can protect the structure between the second mounting frame and the second moving frame. The drag chain moves orderly in the chain guide groove and guide groove, storing the mechanism's pipelines and avoiding entanglement and wear of the pipelines due to horizontal movement, ensuring the safety and reliability of operation, and enabling the mechanism to adjust its position more flexibly in the horizontal direction to adapt to different clamping needs.

[0013] With the buffer mechanism in place, the hydraulic tank provides hydraulic power, and the hydraulic rod works in conjunction with the buffer spring to provide initial buffering when the clamping plate contacts the material. The connecting plate in the mounting slot is connected to the buffer plate, and the buffer plate is connected to the fixed plate. When the fixed plate is impacted, the buffer plate and the connecting plate further absorb the impact force. In addition, the buffer pad on the clamping plate, the multiple buffer structure effectively reduces the impact force on the material during clamping and protects the material from damage. It is especially suitable for clamping fragile or high-precision materials. Furthermore, the bidirectional drive motor drives the threaded rod to rotate, causing the slide plate to slide in the groove of the second mounting plate, thereby driving the clamping plate to clamp or release the material.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please see Figure 1 - Figure 3As shown, this embodiment proposes a quickly switchable hydraulic clamping mechanism, which includes: a main body 1, with a vertical moving unit and a horizontal moving unit on one side of the main body 1. The vertical moving unit includes the main body 1, a first mounting frame 2, a first air pump 3, a first mounting plate 4, a flexible guide rail 5, a first telescopic cloth 6, and a first moving frame 7. The first mounting frame 2 is fixedly connected to one side of the main body 1, and the first air pump 3 is fixedly connected to the upper surface of the first mounting frame 2. The first mounting plate 4 is fixedly connected inside the main body 1, and the flexible guide rail 5 is fixedly connected to one side of the first mounting plate 4. The first telescopic cloth 6 is movably connected to one side of the main body 1, and the first moving frame 7 is movably connected to one side of the first telescopic cloth 6. The first air pump 3 is interconnected with the interior of the first moving frame 7 through an air pipe. One side of the flexible guide rail 5 is interconnected with one side of the second mounting frame 8. When a vertical moving operation is required, the first air pump 3 is activated, transmitting power to the interior of the first moving frame 7 through the air pipe. Under the driving force of the first air pump 3, the first moving frame 7 begins to move along... When the vertical movement occurs, since the first telescopic cloth 6 is movably connected to the main body 1 on one side and to the first movable frame 7 on the other side, the first telescopic cloth 6 will extend and retract during the vertical movement of the first movable frame 7. This will dynamically shield and protect the gap between the main body 1 and the first movable frame 7, preventing external dust, debris, etc. from entering the interior and affecting the operation of the mechanism. At the same time, the flexible guide rail 5 on one side of the first mounting plate 4 fixed inside the main body 1 is connected to the second mounting frame 8 on one side. The second mounting frame 8 is fixedly connected to the upper surface of the first movable frame 7. Therefore, when the first movable frame 7 moves vertically, it will drive the second mounting frame 8 to move synchronously. The flexible guide rail 5 will provide precise guidance and constraint for the movement of the second mounting frame 8, ensuring that the first movable frame 7 and the structure connected to it remain stable during the vertical movement, avoiding deviation or shaking, and ensuring the accuracy and stability of the vertical movement. When the movement reaches the required position, the first air pump 3 stops working, and the first movable frame 7 stops moving, completing the vertical movement operation.

[0021] like Figure 1As shown, the lateral movement unit includes a first moving frame 7, a second mounting frame 8, a fixed box 9, a groove 10, a second air pump 11, an air rod 12, a second telescopic cloth 13, a second moving frame 14, a drag chain 15, a chain guide groove 16, and a guide groove 17. The second mounting frame 8 is fixedly connected to the upper surface of the first moving frame 7. The fixed box 9 is fixedly connected to one side of the second mounting frame 8. The fixed box 9 has a groove 10 inside, and the second air pump 11 is fixedly connected inside the groove 10. An air rod 12 is fixedly connected to the output end of one side of the second air pump 11. A pair of second telescopic cloths 13 are movably connected to one side of the second mounting frame 8. A second movable frame 14 is movably connected to one side of a pair of second telescopic fabrics 13. A drag chain 15 is provided on one side of the second movable frame 14. A chain guide groove 16 is fixedly connected to the upper surface of the second mounting frame 8. A guide groove 17 is opened on one side of the second movable frame 14. One side of the drag chain 15 is interconnected with the interior of the guide groove 17 and the interior of the chain guide groove 16. When a lateral movement operation is required, the second air pump 11 in the groove 10 inside the fixed box 9 is started. The power generated at its output end is transmitted to the second movable frame 14 through the air rod 12. Under the action of this driving force, the second movable frame 14 begins to move in the lateral direction. Since one side of the second mounting frame 8 is movably connected to a pair of second telescopic fabrics 13, and the other side of the pair of second telescopic fabrics 13 is movably connected to the second movable frame 14, the second telescopic fabrics 13 will extend and retract during the lateral movement of the second movable frame 14. This forms a dynamic protection for the space between the second mounting frame 8 and the second movable frame 14, preventing external dust, debris, etc., from entering and affecting the normal operation of the mechanism. Simultaneously, a drag chain 15 is provided on one side of the second movable frame 14, one side of which is connected to the interior of the guide groove 17 and the chain guide groove 16. The chain guide groove 16 is fixed to the second... On the upper surface of the mounting frame 8, the guide groove 17 is opened on one side of the second movable frame 14. When the second movable frame 14 moves laterally, the drag chain 15 will move synchronously under the joint constraint of the chain guide groove 16 and the guide groove 17. This can not only store and protect the pipeline of the mechanism, preventing the pipeline from getting tangled or worn due to movement, but also provide a certain guiding assistance for the movement of the second movable frame 14, ensuring the stability of the movement process. When the second movable frame 14 moves to the preset lateral position, the second air pump 11 stops working, the air rod 12 no longer outputs power, and the second movable frame 14 stops moving, completing the lateral movement operation.

[0022] Preferred, such as Figure 2 and Figure 3As shown, a buffer mechanism is also provided on the lower surface of the second movable frame 14. The buffer mechanism includes a hydraulic tank 18, a mounting groove 19, a connecting plate 20, a buffer plate 21, a hydraulic rod 22, a buffer spring 23, a fixing plate 24, a bidirectional drive motor 25, a threaded rod 26, a sliding plate 27, a second mounting plate 28, a sliding groove 29, and a clamping plate 30. The hydraulic tank 18 is fixedly connected inside the second movable frame 14. Mounting grooves 19 are opened on the left and right sides of the hydraulic tank 18. The connecting plate 20 is slidably connected inside the mounting groove 19. The buffer plate 21 is fixedly connected to one side of the connecting plate 20. The hydraulic rod 22 is fixedly connected to the output end of the lower surface of the hydraulic tank 18. The buffer spring 23 is fixedly connected to the output end of the lower surface of the hydraulic rod 22. The lower surface of the buffer spring 23 is fixedly connected to... A fixed plate 24 is provided, and a bidirectional drive motor 25 is fixedly connected to the upper surface of the fixed plate 24. Threaded rods 26 are fixedly connected to the output ends on both sides of the bidirectional drive motor 25. A sliding plate 27 is threadedly connected to the outer wall of the threaded rod 26. A second mounting plate 28 is fixedly connected to the lower surface of the fixed plate 24. Slide grooves 29 are provided on both sides of the second mounting plate 28. A clamping plate 30 is fixedly connected to the lower surface of the sliding plate 27. A buffer pad 31 is fixedly connected to one side of the clamping plate 30. One side of the buffer plate 21 is connected to one side of the fixed plate 24. When a clamping operation is required, the bidirectional drive motor 25 is started, and its output ends on both sides drive the threaded rods 26 to rotate. Since the outer wall of the threaded rod 26 is threadedly connected to the sliding plate 27, and the lower surface of the sliding plate 27 is connected to the clamping plate... The clamping plate 30 is fixedly connected, and the sliding plate 27 can slide in the grooves 29 on both sides of the second mounting plate 28. Therefore, when the threaded rod 26 rotates, it will drive the sliding plate 27 to move inward along the grooves 29, thereby causing the clamping plate 30 to move inward synchronously, thus clamping the material. The buffer pad 31 on one side of the clamping plate 30 can play a preliminary buffering and protection role when in contact with the material, avoiding scratches on the material surface. During the clamping process, if the clamping plate 30 is subjected to the reaction force of the material or external impact, the impact force will be transmitted to the fixed plate 24. Since the upper surface of the fixed plate 24 is connected to the hydraulic rod 22 through the buffer spring 23, and the hydraulic rod 22 is connected to the output end of the lower surface of the hydraulic tank 18, the buffer spring 23 will undergo elastic deformation, and the hydraulic rod 22 will also be affected by the hydraulic pressure. The hydraulic system provided by the box 18 extends and retracts to absorb part of the impact force, thus providing a buffering effect. At the same time, one side of the fixed plate 24 is connected to the buffer plate 21. The buffer plate 21 is slidably connected to the mounting grooves 19 on the left and right sides of the hydraulic box 18 through the connecting plate 20. When the fixed plate 24 is impacted and undergoes a slight displacement, it will drive the buffer plate 21 and the connecting plate 20 to slide in the mounting grooves 19, further dispersing and transmitting the impact force to the hydraulic box 18. Through the synergistic effect of multiple components, the impact force on the entire mechanism and the material is effectively reduced. When the clamping operation is completed and the material needs to be released, the bidirectional drive motor 25 rotates in the opposite direction, driving the threaded rod 26 to rotate in the opposite direction, causing the slide plate 27 to move outward along the slide groove 29, and the clamping plate 30 moves outward accordingly to release the material.

[0023] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
