[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-3 As shown, this utility model provides a technical solution: a multifunctional robotic arm attachment, including a base 1, a robotic arm 2 mounted on the top of the base 1, a cross-shaped fixing plate 3 fixedly mounted on the right side of the robotic arm 2, and a connecting rod 4 fixedly mounted on the outer side of the cross-shaped fixing plate 3, which connects to the outer surface of the robotic arm 2. The connecting rod 4 serves to stabilize the connection between the cross-shaped fixing plate 3 and the robotic arm 2, enhancing the stability of the overall structure. An extension plate 5 is fixedly mounted on the right side of the cross-shaped fixing plate 3, and a cross-shaped clamping plate 6 is fixedly mounted on the right side of the extension plate 5. A clamping and fixing device 7 is provided inside the cross-shaped clamping plate 6.

[0021] The clamping and fixing device 7 includes a drive motor 701 fixedly installed on the right side of the cross-shaped fixing plate 3. The drive motor 701 serves as a power source, providing power for the entire clamping action. A worm gear 702 is fixedly installed at the output end of the drive motor 701. A rotatable rotating column 703 is provided on the right side of the cross-shaped fixing plate 3. A worm wheel 704 is fixedly installed on the outer surface of the rotating column 703. The worm gear 702 meshes with the worm wheel 704. Through the transmission structure of the worm gear 702 and the worm wheel 704, the power is transmitted and the direction of motion is changed. A rotating square plate 705 is fixedly installed on the right side of the rotating column 703. A rotatable bent rod 706 is provided on the outer side of the rotating square plate 705. A clamping inclined rod 707 is fixedly installed on the right side, and an auxiliary plate 708 is fixedly installed on the right side of the clamping inclined rod 707. A compression spring 709 is fixedly installed on the lower surface of the auxiliary plate 708, and a pressing block 710 that passes through the clamping inclined rod 707 is fixedly installed at the bottom end of the compression spring 709. Through this structural design, the drive motor 701 drives the worm gear 702 to rotate, which in turn causes the worm wheel 704, the rotating cross column 703, and the rotating square plate 705 to rotate. The bending rod 706 drives the clamping inclined rod 707 to move, thereby realizing the clamping action of the object. At the same time, the compression spring 709 and the pressing block 710 can adaptively adjust according to the shape and size of the object to ensure the stability of the clamping.

[0022] Specifically, such as Figure 3As shown, a long strip-shaped through hole is provided on the right side of the cross clamping plate 6, and a movable horizontal column is fixedly installed on the left side of the clamping diagonal rod 707. The movable horizontal column slides inside the long strip-shaped through hole. This structural design provides guidance and support for the movement of the clamping diagonal rod 707, ensuring the stability and accuracy of the clamping diagonal rod 707 during movement. A circular through hole is provided on the right side of the clamping diagonal rod 707, and the pressing block 710 slides inside the circular through hole. The circular through hole allows the pressing block 710 to move flexibly in the vertical direction. The device is designed to adapt to the surface shape of different objects and enhance the gripping effect. There are four sets of pressing blocks 710, and the inner surfaces of the four sets of pressing blocks 710 are provided with friction anti-slip textures to increase friction and prevent the gripped object from slipping during the gripping process, thereby improving the reliability of the gripping. There are also four sets of bending rods 706, and the length of each set of bending rods 706 is 650 mm. This design ensures the structural symmetry and stability of the gripping and fixing device 7, while the appropriate length can meet the gripping needs of various objects.

[0023] The working principle of this utility model is as follows:

[0024] S1. When it is necessary to grasp an object, start the drive motor 701. The output end of the drive motor 701 drives the worm 702 to mesh with the worm wheel 704, which in turn drives the rotating horizontal column 703 and the rotating square plate 705 to rotate. The opening and closing of the clamping inclined bar 707 is controlled by the bending rod 706 to complete the grasping and releasing action of the object.

[0025] S2. During the gripping process, the adaptive structure composed of the compression spring 709 and the pressing block 710 can automatically adjust the clamping force and angle according to the shape and size of the object to ensure stable clamping of different objects.

[0026] S3. The robotic arm 2 moves on the work platform via the base 1, driving the clamping and fixing device 7 and the object being gripped to move to the designated position to complete the handling and other operation tasks.

[0027] In summary, this multifunctional robotic arm attachment, through the drive motor 701 driving the worm gear 702 and worm wheel 704 to mesh, drives the rotating square plate 705 and bending rod 706 to move the clamping inclined rod 707 and pressing block 710 inward, thereby achieving the grasping operation of objects. It can flexibly grasp objects of different shapes and sizes without the need for frequent attachment changes, greatly reducing the complexity and time cost of operation, improving production efficiency, and further enhancing the versatility and multifunctionality of the robotic arm attachment.

[0028] This multi-functional robotic arm attachment enhances the gripping stability of objects by setting friction anti-slip texture on the inner side of the pressing block 710 and utilizing the adaptive adjustment function of the compression spring 709 and the pressing block 710, thus preventing objects from falling during grasping and handling and ensuring the safety and reliability of the production process.
