Description

Technical Field

[0001] This utility model relates to a gripping device for a robotic arm, belonging to the technical field of robotic arms (B25J9 / 06) characterized by multi-hinged claw arms. Background Technology

[0002] Manufacturing, as a core pillar of my country's national economy, is not only the leading force of economic growth but also the cornerstone of economic transformation. In the production process of industrial support workshops, robotic arms are one of the key productivity devices. With the continuous increase in production demands, robotic arm technology is also constantly improving. However, existing robotic arms still have shortcomings in their workpiece gripping performance, especially with frequent rotations in angle and orientation, where gripping stability becomes increasingly prominent. Modern robotic arms are increasingly designed with flexibility in mind, enabling more complex rotation and positioning operations. However, while this flexibility improves production efficiency, it also brings about gripping instability. In applications requiring frequent adjustments to gripping angle and orientation, the gripping effect of robotic arms is often affected, leading to potential workpiece displacement or insecure gripping. This instability not only affects the continuity of the production process but may also negatively impact the quality of the final product.

[0003] Therefore, there is an urgent need for a gripping device that can maintain stable gripping even when the robotic arm rotates frequently. Utility Model Content

[0004] The technical problem to be solved by this invention is: how to improve the gripping stability of a robotic arm during rotation.

[0005] The technical solution proposed by this utility model to solve the above-mentioned technical problems is: a gripping device for a robotic arm, including a rotating disk, the rotating disk being screwed to the fixed end of a hydraulic rod, the telescopic end of the hydraulic rod passing through the interior of a connecting disk and being hinged to multiple grippers via multiple second hinges, the telescopic movement of the hydraulic rod driving the opening and closing of the multiple grippers; the connecting disk and the rotating disk being fixed together by multiple support rods, the connecting disk being hinged to the multiple grippers via multiple third hinges respectively.

[0006] Furthermore, the gripping ends of the plurality of grippers are respectively fixed with arc-shaped pieces, and the inner wall of the arc-shaped pieces is provided with anti-slip ridges.

[0007] Furthermore, the telescopic end of the hydraulic rod is fixed with multiple first pins to form multiple second hinges; the connecting disc is fixed with multiple second pins to form multiple third hinges.

[0008] Furthermore, the rotating disk and the connecting disk are provided with multiple insertion holes, one end of the multiple support rods is inserted into the insertion hole on the rotating disk, and the other end of the multiple support rods is inserted into the insertion hole on the connecting disk.

[0009] The beneficial effects of this invention are as follows: First, the rotating disk is screwed to the fixed end of the hydraulic rod, ensuring sufficient support force during the robotic arm's gripping process. Second, the telescopic end of the hydraulic rod passes through the interior of the connecting disk and is hinged to multiple grippers via multiple second hinges, enabling the grippers to achieve precise and stable opening and closing movements under the extension and retraction of the hydraulic rod, effectively improving gripping stability. Since the connecting disk and the rotating disk are fixed together by multiple support rods, and both the rotating disk and the connecting disk have multiple insertion holes, one end of each support rod is inserted into a hole on the rotating disk, and the other end is inserted into a hole on the connecting disk. These support rods not only provide stability but also effectively reduce shaking or offset during gripping, while also facilitating assembly and disassembly. Furthermore, since the connecting disk is hinged to multiple grippers via multiple third hinges, stable gripping performance is maintained even when the grippers are rotating. In summary, this multi-layered, multi-hinged, and support rod structure design allows the grippers to maintain efficient and reliable gripping performance under complex working conditions, significantly improving work efficiency and safety.

[0016] Example

[0017] One embodiment of the robotic gripper is as follows: Figure 1 , 2As shown, the device includes a rotating disk 1, which is screwed to the fixed end of a hydraulic rod 2. Multiple first pins 3 are fixed to the telescopic end of the hydraulic rod 2, forming multiple second hinges. The telescopic end of the hydraulic rod 2 passes through the interior of a connecting disk 4 and is hinged to multiple grippers 5 via the multiple second hinges. Each gripper has a hinge point a and a hinge point b, and is divided into two sections by the hinge point b. The hinge point a is located above the hinge point b. The multiple second hinges are hinged to the hinge point a of one section of the grippers 5. The telescopic movement of the hydraulic rod 2 causes the multiple grippers 5 to open and close. The connecting disk 4 is fixed to the rotating disk 1 via multiple support rods 6. The connecting disk 4 is fixed with multiple second pins 7, forming multiple third hinges. The connecting disk 4 is hinged to the hinge point b of the other section of the grippers 5 via the multiple third hinges.

[0018] like Figure 1 As shown, the rotating disk 1 and the connecting disk 4 are provided with multiple insertion holes 8. One end of the multiple support rods 6 is inserted into the insertion hole 8 of the rotating disk 1, and the other end is inserted into the insertion hole 8 of the connecting disk 4.

[0019] like Figure 3 As shown, the gripping ends of multiple claws 5 are respectively fixed with arc-shaped pieces 9, and the inner wall of the arc-shaped pieces 9 is provided with anti-slip ridges 10.

[0020] like Figure 4 As shown, in this embodiment, a gripping device for a robotic arm is mounted on one end of the rotating arm 11 of a robotic arm via a rotating disk 1. The support leg 12 can rotate on the base 13, simultaneously driving the rotating arm 11 to rotate and adjust its orientation. In existing robotic arms, a motor is usually installed inside the rotating arm 11 to control the rotation of the gripping device to adjust the placement angle of the gripped workpiece. However, the gripping device for a robotic arm in this embodiment, through its multi-layered, multi-hinged, and support rod structure design, can still grip stably without deviation even when the robotic arm needs to frequently rotate its angle and orientation. This efficient and reliable gripping performance greatly improves work efficiency.

[0021] This utility model is not limited to the above embodiments. All technical solutions formed by equivalent substitutions fall within the protection scope claimed by this utility model.
