[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1 to 8The diagram illustrates an embodiment of this utility model, relating to an opening and closing clamping and lifting device, comprising a device body 10, which includes a lifting mechanism 20 and a clamping mechanism 30. The lifting mechanism 20 drives the clamping mechanism 30 to move, and is connected to a protective cover 11, which extends along the lower end of the mounting frame towards and covers the clamping mechanism 30. The clamping mechanism 30 includes a cylinder 40, a gripper assembly 50, and an air passage interface 31. The top of the cylinder 40 is assembled and connected to the gripper assembly 50. A cover 32 is connected to the top of the gripper assembly 50, and the cover 32 is connected to the gripper assembly 50. The air passage interface 31 is connected to the side of the cylinder 40 and is used to connect to an external air source to input driving gas into the interior of the cylinder 40 to control the gripper assembly to achieve opening and closing actions. Specifically, the device body 10 consists of a lifting mechanism 20 and a clamping mechanism 30. The lifting mechanism 20 drives the clamping mechanism 30 to move, and the protective cover 11 protects the core components of the device. This design integrates clamping and lifting functions, simplifies the overall structure of the equipment, and the protective cover 11 effectively blocks dust, impurities, and other contaminants from corroding the internal components, extending the service life of the device. At the same time, the opening and closing of the grippers are controlled by air circuits, making operation convenient and providing a basic guarantee for automated operation.

[0032] like Figure 2 As shown, the cylinder body 40 has a mounting plate 41 at the end opposite to the gripper assembly 50. The mounting plate 41 has multiple circumferentially distributed mounting through holes 42, which are used to connect with the lifting mechanism 20. Specifically, the circumferentially distributed through holes make the connection more evenly stressed, avoiding excessive local stress that could cause the connection to loosen, thus improving the overall structural stability of the device. In addition, the standardized through hole design facilitates installation and disassembly, reduces maintenance difficulty, and enhances the versatility of the device.

[0033] like Figure 3As shown, the cylinder body 40 has several coaxially distributed chambers 43 inside, and each chamber 43 is arranged in layers along the axial direction of the cylinder body 40. Each chamber 43 is provided with an annular piston block 44, and adjacent chambers 43 are separated by a seal 45. The seal 45 is an annular partition plate, which is embedded between adjacent chambers 43. A central shaft 46 connected to the annular piston block 44 passes through the center of the cylinder body 40. One end of the central shaft 46 is connected to the gripper assembly 50. A guide sleeve 47 is provided between the central shaft 46 and the cylinder body 40. The guide sleeve 47 is sleeved on the outside of the central shaft 46 and is used to linearly guide the movement of the central shaft 46. Specifically, the cylinder body 40 has multiple chambers 43 arranged in layers. With the help of the annular piston block 44 and the seal 45, the air pressure in each chamber 43 can be precisely controlled, reducing gas leakage and improving the stability of the driving force. The cooperation between the central shaft 46 and the guide sleeve 47 ensures the straightness of the movement of the central shaft 46, avoids deviation from affecting the accuracy of the gripper action, and makes the opening and closing of the gripper more stable and precise. It is suitable for scenarios with high clamping accuracy requirements.

[0034] like Figures 4 to 6 As shown, the gripper assembly 50 includes three gripper blocks 60 and a transmission block 70. Each gripper block 60 is evenly spaced along the circumference of the transmission block 70, and each gripper block 60 is provided with a driven part 61. The transmission block 70 includes an integrally formed base 71 and a transmission part 72. The base 71 is connected to the central shaft 46. The transmission part 72 is drively connected to the driven part 61. Specifically, the even distribution of the three gripper blocks 60 along the circumference of the transmission block 70 allows the gripping force to be applied evenly to the object, preventing the object from tilting or slipping due to uneven force. The transmission connection between the transmission block 70 and the central shaft 46 is simple and reliable, efficiently converting the linear motion of the central shaft 46 into the opening and closing action of the grippers, improving the gripping response speed and stability.

[0035] like Figure 5 As shown, the driven part 61 has a connecting groove 62, and a mating surface 63 is provided on one side of the connecting groove 62. Specifically, the connecting groove 62 of the driven part 61 provides passage space for the transmission arm 73, while the mating surface 63 ensures tight contact between the transmission arm 73 and the driven part 61, reduces transmission gap, avoids lag or jamming, makes the opening and closing action of the gripper smoother, and improves transmission efficiency.

[0036] like Figure 6As shown, the transmission part 72 is provided with at least three transmission arms 73 in the circumferential direction. Each transmission arm 73 extends outward at an incline along the circumferential direction of the transmission part 72. Each transmission arm 73 has a transmission inclined surface 74 on its outer side. The transmission inclined surface 74 is used to contact the mating surface 63, so that the movement of the transmission block 70 is converted into the radial swing of the gripper block 60, realizing the opening and closing action of the gripper. Specifically, the transmission arm 73 extends at an incline and is provided with a transmission inclined surface 74. When the inclined surface contacts the mating surface 63, it can smoothly convert the axial movement of the transmission block 70 into the radial swing of the gripper block 60. The force is uniform during the transmission process, which can adapt to the clamping requirements of objects of different sizes, while avoiding rigid impact and extending the service life of the component.

[0037] like Figure 7 As shown, the lifting mechanism 20 includes a lifting drive module 21 and a connecting member 80. The output end of the lifting drive module 21 is connected to the connecting member 80 and is used to drive the connecting member 80 to move linearly in the vertical direction. Specifically, the lifting drive module 21 drives the clamping mechanism 30 to lift and lower through the connecting member 80, so that the lifting and clamping actions are closely connected. The drive module can provide a stable driving force to ensure that the lifting process is smooth and controllable. The design of the connecting member 80 ensures the effective transmission of force, improves the accuracy of the lifting action, and meets the needs of different height operations.

[0038] like Figure 7 As shown, the lifting drive module 21 is a lifting cylinder, which is connected to a mounting frame 22. A mounting base plate 23 is provided on one side of the mounting frame 22. Specifically, the lifting drive module 21 uses a lifting cylinder, which has a fast response speed, stable output force, and can precisely control the lifting stroke. The mounting frame 22 and the mounting base plate 23 provide a stable support foundation for the device, facilitating its integration into different automated production lines and enhancing its installation adaptability.

[0039] like Figure 8 As shown, the inner side of the connector 80 is provided with a mounting surface 81, and a slider 82 is connected to the mounting surface 81. The slider 82 is slidably connected to a linear slide rail 83, and the linear slide rail 83 is fixedly connected to one side of the mounting base plate. The end of the connector 80 facing away from the slider 82 is installed and connected to the protective cover 11. Specifically, the connector 80 is slidably connected to the linear slide rail 83 on the mounting base plate through the slider 82, which can limit the movement trajectory of the connector 80, ensure the straightness of the lifting process, and reduce shaking. At the same time, the connector 80 is connected to the protective cover 11, so that the protective cover 11 moves synchronously with the clamping mechanism 30, continuously exerting a protective function and further improving the reliability of the device.

[0040] like Figure 8As shown, the connector 80 has a clearance groove 84 located below the mounting surface 81. The clearance groove 84 provides clearance space for the slider 82 to move along the linear slide rail 83, thereby preventing interference between the slider 82 and the connector 80. Specifically, the clearance groove 84 provides sufficient space for the movement of the slider 82, avoiding mechanical interference between the slider 82 and the connector 80, ensuring the smooth movement of the slider 82 along the slide rail, reducing movement resistance, and improving the operating efficiency and service life of the lifting mechanism 20.

[0041] The working principle of this utility model is as follows:

[0042] In the lifting mechanism 20, the lifting drive module 21 drives the clamping mechanism 30 to move vertically via the connector 80. The slider 82 on the connector 80 cooperates with the linear guide rail 83 on the mounting base plate to ensure the linear accuracy of the lifting movement. The clearance groove 84 avoids interference between the slider 82 and the connector 80, ensuring smooth lifting. In the clamping mechanism 30, an external air source inputs gas into different chambers 43 of the cylinder 40 via the air circuit interface 31. The air pressure difference in the chambers 43 drives the annular piston block 44 to move the central shaft 46. The central shaft 46 transmits the motion to the gripper block 60 through the transmission block 70. The transmission inclined surface 74 of the transmission arm 73 contacts the mating surface 63 of the driven part 61 of the gripper block 60, causing the gripper block 60 to swing radially to open and close. The protective cover 11 moves synchronously with the connector 80 to continuously protect the internal components. By coordinating and controlling the lifting drive module 21 and the air circuit pressure, precise clamping, lifting, and placement of objects are achieved.

[0043] This utility model integrates lifting and clamping functions, realizing integrated lifting and clamping operations and simplifying the overall structure of automated equipment. The design of the multi-chamber cylinder 40, precision transmission structure and guide components improves the accuracy and stability of the gripper opening and closing and lifting actions. The detailed design of the protective cover 11 and the avoidance groove 84 enhances the protective performance and smooth operation of the device. The overall structure is compact, easy to install and maintain, and can adapt to various automated production scenarios, improving work efficiency and reliability.

[0044] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
