[0002] With the development of artificial intelligence and mechanical automation in recent years, the main objects of industrial production have gradually shifted from manual labor to machinery. Compared with manual production, mechanical production has the significant characteristics of high continuity, high efficiency and high quality. Therefore, the use of mechanical equipment such as bionic devices like robotic arms for production and processing activities has gradually become the mainstream. Bionic robotic arms need to change the gripping mechanism of different shapes to grip objects of different shapes.

[0003] Patent application number 202222469052.6 discloses a bionic robotic arm. Through the setting of the gripper mechanism, when clamping a product, it can not only provide stable clamping, but also scan and identify the product simultaneously, mimicking the effect of the human eye. Furthermore, through the cooperation of a connector and a second motor, the device can mimic the rotation of a human hand when necessary, further adjusting the orientation of the clamped product.

[0004] The above technical solution uses a motor to move the clamping plate to clamp the item. However, since the clamping mechanism is fixedly installed, it is difficult to disassemble and replace the clamping mechanism, which cannot meet the clamping requirements of items of different shapes. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a bionic robotic arm to solve the technical problem that the clamping mechanism is fixedly installed, making it difficult to disassemble and replace, and thus unable to meet the clamping requirements of items of different shapes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bionic robotic arm, comprising a bionic robotic arm body and a mounting base rotatably disposed in the bionic robotic arm body. The mounting base has ear plates symmetrically fixed on its side walls, and an axial positioning connection hole is provided at the center of the mounting base. A connecting rod is inserted into the axial positioning connection hole, and a clamping seat is fixed on the connecting rod. Positioning rods are elastically inserted into both ends of the clamping seat, and one end of the positioning rod extending out of the telescopic hole is engaged with the ear plate.

[0007] The present invention is further provided that both ends of the clamping seat are provided with telescopic holes for accommodating the positioning rod, and a spring is embedded in the telescopic hole.

[0008] The present invention is further configured such that a through hole is provided on the ear plate, and the positioning rod is fitted into the through hole.

[0009] The present invention is further configured such that both ends of the clamping seat are fixed with protrusions, and the side walls of the two protrusions are provided with sliding grooves.

[0010] The present invention is further configured such that a double-threaded screw is rotatably mounted between the two slides, and a first motor connected to the double-threaded screw is mounted on the side wall of the protrusion.

[0011] The present invention is further configured such that a clamping plate is installed on the side wall of the protrusion, and an anti-slip pad is fixed at one end of each of the two clamping plates that are close to each other, and the two clamping plates are fitted into the slide groove. The two ends of the double threaded screw with opposite thread directions are respectively threaded into the two clamping plates.

[0012] The present invention is further configured such that one end of the bionic robotic arm body has a plurality of mounting screw holes arranged in a ring array, and the other end of the bionic robotic arm body is provided with a mounting compartment.

[0013] The present invention is further configured such that a second motor connected to the mounting base is fixed in the mounting compartment, and the outer wall of the bionic robotic arm body is provided with heat dissipation grooves in a ring array that are connected to the mounting compartment.

[0014] In summary, this utility model has the following advantages: The utility model features a mounting base rotatably mounted on the main body of the bionic robotic arm. The connecting rod on the clamping base is inserted into the axial positioning connection hole. Simultaneously, the clamping base moves between the two ear plates, and the spring in the telescopic hole pushes the positioning rod into the through hole to keep the clamping base fixed. The positioning rod is squeezed out of the through hole by the side wall of the ear plate to remove the connecting rod, thus improving the convenience of disassembling and replacing the clamping base. Furthermore, by fixing protrusions at both ends of the clamping base, the first motor drives the double-threaded screw to rotate after startup, and during the rotation, it drives the two clamping plates to move towards each other, improving the convenience of clamping objects.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] A bionic robotic arm, such as Figure 1-4 As shown, the device includes a bionic robotic arm body 1 and a mounting base 18 rotatably disposed in the bionic robotic arm body 1. The mounting base 18 has ear plates 15 symmetrically fixed on its side walls, and an axial positioning connection hole 17 is provided at the center of the mounting base 18. A connecting rod 14 is inserted into the axial positioning connection hole 17, and a clamping seat 2 is fixed on the connecting rod 14. Both ends of the clamping seat 2 are elastically inserted with positioning rods 11, and one end of the positioning rod 11 extending out of the telescopic hole 13 is engaged with the ear plate 15.

[0022] Both ends of the clamping base 2 are provided with telescopic holes 13 for accommodating the positioning rod 11. A spring 12 is embedded in the telescopic hole 13. The ear plate 15 is provided with a through hole 16, and the positioning rod 11 is inserted into the through hole 16. One end of the bionic robotic arm body 1 is provided with multiple mounting screw holes 4 in a circular array, and the other end of the bionic robotic arm body 1 is provided with a mounting chamber 19. The bionic robotic arm body 1 is installed and fixed by bolts connecting to the mounting screw holes 4. A second motor 20 connected to the mounting base 18 is fixed in the mounting chamber 19. The outer wall has heat dissipation grooves 3 arranged in a ring array and connected to the mounting chamber 19. After the second motor 20 is started, it drives the mounting base 18 and the clamping base 2 to rotate. During the rotation, the clamping angle of the clamping plate 8 is adjusted. The connecting rod 14 on the clamping base 2 is inserted into the axial positioning connecting hole 17. At the same time, the clamping base 2 moves between the two ear plates 15. The spring 12 in the telescopic hole 13 pushes the positioning rod 11 into the through hole 16 to keep the clamping base 2 fixed. The positioning rod 11 is squeezed from the side wall of the ear plate 15 and removed from the through hole 16 to disassemble the connecting rod 14.

[0023] Furthermore, both ends of the clamping seat 2 are fixed with protrusions 5, and the side walls of the two protrusions 5 are provided with sliding grooves 9. A double threaded screw 7 is rotatably installed between the two sliding grooves 9. A first motor 10 connected to the double threaded screw 7 is installed on the side wall of the protrusion 5. A clamping plate 8 is installed on the side wall of the protrusion 5. Anti-slip pads 6 are fixed at the near ends of the two clamping plates 8, and the two clamping plates 8 are fitted into the sliding grooves 9. The two ends of the double threaded screw 7 with opposite thread directions are respectively threaded into the two clamping plates 8. After the first motor 10 is started, it drives the double threaded screw 7 to rotate, and during the rotation, it drives the two clamping plates 8 to move towards each other for clamping.

[0024] The working principle of this utility model is as follows: When in use, the second motor 20 is started to drive the mounting base 18 and the clamping base 2 to rotate, so that the clamping plate 8 corresponds to the clamped item. After the first motor 10 is started, it drives the double threaded screw 7 to rotate, and during the rotation, it drives the two clamping plates 8 to move towards each other, so that the two clamping plates 8 clamp and fix the item. When clamping items of different shapes, the positioning rod 11 is squeezed from the side wall of the ear plate 15 and moved out of the through hole 16. After it is moved out, the connecting rod 14 is moved out of the axial positioning connection hole 17. When changing different models of clamping base 2 and clamping plate 8, the connecting rod 14 on the clamping base 2 is inserted into the axial positioning connection hole 17. At the same time, the clamping base 2 moves between the two ear plates 15. The spring 12 in the telescopic hole 13 pushes the positioning rod 11 into the through hole 16 to keep the clamping base 2 fixed, which improves the convenience of disassembling and replacing the clamping base 2.
