[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] like Figures 1 to 5 As shown, a palletizing gripper device suitable for multi-specification workpieces in one embodiment of this utility model includes a support plate 1. A rotating plate 13 is rotatably connected above the support plate 1. The two ends of the rotating plate 13 are hinged to first connecting blocks 16 by pins. Each first connecting block 16 is connected to a connecting rod 5 on its outside. Each connecting rod 5 is connected to a second connecting block 15 at one end close to each other. Each second connecting block 15 is provided with a connecting mechanism on its outside. A driving mechanism is provided above the rotating plate 13. By setting the rotating plate 13 on the support plate 1 and using the first connecting blocks 16, connecting rods 5 and second connecting blocks 15 hinged at both ends of the rotating plate 13 to form a symmetrical linkage mechanism, the rotational motion of the driving mechanism is accurately converted into the linear motion of the connecting mechanisms on both sides. This core transmission mechanism ensures that the device only needs one driving source to synchronously drive the clamping units on both sides to move towards or away from each other, realizing adaptive clamping of workpieces of different specifications and significantly improving the versatility and flexibility of the device.

[0025] The drive mechanism includes a support frame 9 connected above the support plate 1, a motor 8 mounted above the support frame 9, and the output end of the motor 8 connected to the rotating plate 13. Each connection mechanism includes a mounting block hinged to the second connecting block 15. A first mounting plate 7 is connected to the outside of each mounting block. Two slide rails 2 are opened above the support plate 1. A slide rod 3 is connected inside each slide rail 2. A limit block 14 is connected inside each slide rail 2. Each limit block 14 is sleeved on the outside of the slide rod 3. By setting up a drive mechanism composed of the support frame 9 and the motor 8, a stable and reliable power source is provided for the entire gripper, ensuring the efficient transmission of driving force. The slide rails 2 and slide rods 3 opened on the support plate 1 constitute the basic guide rail for the movement of the clamping unit, ensuring the linearity and stability of the clamping components during the movement process and effectively preventing lateral swaying. The design of the limit block 14 being fitted outside the slide bar 3 plays a crucial role in mechanical limiting and protection. It can prevent the slider 17 from detaching from the slide bar 3 during high-speed movement, thereby improving the safety and reliability of the equipment. It can also protect the motor 8 from overload impact by limiting the stroke.

[0026] An annular groove 12 is provided above the support plate 1, and the annular groove 12 is slidably connected to the rotating plate 13. Two sliders 17 are slidably connected to the outside of each slider 3. A top block 4 is connected to the top of each slider 17 via a support rod 18. A fixing rod 10 is connected to one end of each set of sliders 17 and top block 4. A second mounting plate 11 is connected to one end of each fixing rod 10. A clamping plate 6 is connected to the outside of each set of first mounting plates 7 and second mounting plates 11. Anti-slip texture is provided on the outside of each clamping plate 6. By adding the annular groove 12 that is slidably connected to the rotating plate 13, the stability and load-bearing performance of the rotating plate 13 in rotational motion are greatly optimized, enabling it to transmit torque more smoothly and accurately, and resist overturning moments that may be caused by cantilever structure or uneven load. Through the combination of sliders 17, support rods 18, top blocks 4 and fixing rods 10, the linear motion on the slider 3 is stably transmitted to the second mounting plate 11, which together with the first mounting plate 7 constitutes a complete clamping execution end.

[0027] Working principle: When the motor 8 starts, its output shaft drives the rotating plate 13 to rotate around the center. The rotation of the rotating plate 13 is converted into a planar composite motion of the connecting rod 5 through the first connecting block 16 hinged at both ends. The other end of the connecting rod 5 is connected to the mounting block and the first mounting plate 7 through the second connecting block 15, thereby accurately converting the rotational motion of the rotating plate 13 into the linear motion of the first mounting plates 7 on both sides on the slide rod 3, either towards or away from each other. During this process, the annular slide groove 12 provides stable rotational support for the rotating plate 13, ensuring smooth movement and structural rigidity. Since the first connecting block 16, the connecting rod 5 and the second connecting block 15 on both sides form a completely symmetrical linkage mechanism, the motor 8 can synchronously drive the first mounting plates 7 on both sides at the same speed when rotating in both directions. This synchronous linkage mechanism, whether moving closer or further away, allows the device to automatically adapt to workpieces of different widths with only one drive source, achieving adaptive clamping. Simultaneously, the slider 17 drives the second mounting plate 11 to move synchronously with the first mounting plate 7 via the support rod 18 and the fixing rod 10, ensuring the consistency of the upper and lower clamping points. The clamping plate 6, installed on the first mounting plate 7 and the second mounting plate 11, serves as the final execution component, contacting the workpiece from the top, bottom, or sides. The anti-slip texture on the surface of the clamping plate 6 effectively increases friction, preventing the workpiece from slipping during handling. Throughout the entire movement, the cooperation between the slide rod 3 and the slider 17 ensures the straightness and stability of the movement trajectory, while the limiting block 14 acts as a mechanical hard limit, preventing overtravel and protecting the entire mechanism.
