Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arms, in particular to a mechanical arm locking device. Background Art

[0002] In the highly integrated and precisely configured automated production process, robotic arms, as the core actuators, bear multiple crucial responsibilities. They are not only responsible for efficient and stable material handling operations, but also accurately perform assembly tasks, providing indispensable and solid support for improving overall production efficiency and excellent product quality.

[0003] However, traditional robotic arm locking devices generally have the defects of low control accuracy and insufficient locking force, which can easily cause the robotic arm to accidentally move or fall off during the operation process. Although there are improved technologies that increase the locking force by increasing the complexity of the locking structure, these methods often lead to a significant increase in equipment costs.

[0004] Therefore, in view of the common defects of the above-mentioned traditional robotic arm locking devices, such as low control accuracy and lack of locking force, which easily cause the robotic arm to accidentally move or fall off during the operation process, a robotic arm locking device can be designed. Through the coordination of the rotating structure, telescopic structure and locking structure, it not only ensures the horizontal rotation movement of the robotic arm, but also provides a strong locking force, effectively preventing the robotic arm from accidentally moving or falling off during the operation process.

This interface 4 adopts a standardized design and can be compatible with a variety of different types of mechanical hands, which is convenient for users to replace according to specific needs. The base 2 is the supporting structure of the mechanical arm locking device, which provides stable support for the entire device. The telescopic structure is an important part of the mechanical arm locking device, which realizes the movement of the second locking disk 9 in the vertical direction, the telescopic The structure adopts a hydraulic drive mode and has the advantages of compact structure and precise control. The rotating structure realizes the horizontal rotation of the robot arm body 1. The locking structure is responsible for providing a strong locking force between the robot arm body 1 and the base 2 to prevent the robot arm body 1 from accidentally moving or falling off during operation. The robot arm body 1 is equipped with sensors, which are electrically connected to the telescopic structure, rotating structure and locking structure. These sensors include position sensors and force sensors. This design enables the sensors to obtain key data such as the motion state, position information, force or torque of the robot arm in real time and accurately. The sensors interact with the various structures of the robot arm through electrical signals. When the robot arm performs actions such as telescoping, rotating or locking, the sensors will capture the tiny changes caused by these actions and convert them into electrical signals for transmission. These electrical signals are then sent to the artificial intelligence control device connected to the robot arm body 1. The artificial intelligence control device can adjust the motion trajectory and speed of the robot arm according to this information to improve work efficiency and safety.

[0025] See also Figure 4In this embodiment, the rotating structure includes a rotating motor 5, a coupling 6 and a rotating shaft 7; the rotating motor 5 is installed in the cavity 3 of the base 2, and the output shaft of the rotating motor 5 is connected to one end of the coupling 6, and the other end of the coupling 6 is connected to the lower end of the rotating shaft 7. The outer wall of the rotating shaft 7 is fixedly connected to the robot arm body 1. The rotating motor 5 is the core power source of the rotating structure and is responsible for providing the driving force required for the horizontal rotation of the robot arm body 1. The rotating motor 5 has the characteristics of small size, high power, and stable speed, which can meet the rotation requirements of the robot arm in various operating scenarios. The coupling 6 is an important component connecting the output shaft of the rotating motor 5 and the rotating shaft 7, ensuring stable connection and efficient transmission between the rotating motor 5 and the rotating shaft 7. The rotating shaft 7 is the support and transmission component for the rotation of the robot arm body 1, and drives the robot arm body 1 to rotate by rotation.

[0026] See also Figure 5 In this embodiment, the locking structure includes a No. 1 locking disk 8 and a No. 2 locking disk 9; the lower end of the robot arm body 1 is integrally fixedly connected to the No. 1 locking disk 8, and the upper end of the base 2 is equipped with a No. 2 locking disk 9 adapted to the No. 1 locking disk 8. The lower end of the No. 1 locking disk 8 and the upper end of the No. 2 locking disk 9 are both provided with mutually engaged locking teeth 10. The lower end of the robot arm body 1 and the base 2 are locked by the locking teeth 10. The No. 1 locking disk 8 is an important component of the locking structure. It is directly fixedly connected to the lower end of the robot arm body 1. This integrated The design not only enhances the stability of the structure, but also ensures a firm connection between the robotic arm body 1 and the No. 1 locking disk 8. The No. 2 locking disk 9 is installed at the upper end of the base 2, corresponding to the No. 1 locking disk 8. The No. 1 locking disk 8 cooperates with the No. 1 locking disk 8 to achieve the locking function. When locking is required, the hydraulic cylinder 11 pushes the No. 2 locking disk 9 upward, so that the locking teeth 10 on the No. 2 locking disk 9 are tightly engaged with the locking teeth 10 at the lower end of the No. 1 locking disk 8. This engagement method is not only stable and reliable, but also can withstand greater tension and torque.

[0027] See also Figure 6 In this embodiment, the telescopic structure is a hydraulic cylinder 11; four hydraulic cylinders 11 are installed in the cavity 3 of the base 2, and the power output end of each hydraulic cylinder 11 is fixedly connected to the lower end of the No. 2 locking disk 9. When the hydraulic cylinder 11 is working, it will push the No. 2 locking disk 9 to move up and down, thereby realizing the locking and unlocking function between the robotic arm body 1 and the base 2.

[0028] During operation, the user controls the sensors inside the robot arm body 1 through an external artificial intelligence control system, thereby causing the rotating structure, locking structure, and telescopic structure to operate automatically. Specifically, these position sensors or force sensors collect data on the robot arm's status and send this data to the control system. The control system calculates the robot arm's motion trajectory and actions based on preset algorithms and programs, as well as the received sensor data. The control system then sends control signals to drive the robot arm's rotating structure, locking structure, and telescopic structure to perform corresponding actions.

[0029] When the robot arm body 1 needs to rotate horizontally, the hydraulic cylinder 11 receives the signal from the sensor and retracts, causing the first locking disc 8 and the second locking disc 9 to separate from each other, so that the locking teeth 10 on the first locking disc 8 and the second locking disc 9 also disengage from each other, achieving the unlocking effect;

[0030] Subsequently, the rotating motor 5 is started, causing the rotating shaft 7 to start rotating, and the robotic arm body 1 to rotate horizontally. After the rotation action is completed, the hydraulic cylinder 11 will push the No. 2 locking disk 9 up, ensuring that the locking teeth 10 on the No. 2 locking disk 9 are tightly engaged with the locking teeth 10 at the bottom of the No. 1 locking disk 8, thereby realizing the locking function again.

[0031] Through the above steps, the robot arm locking device ensures the horizontal rotation of the robot arm through the motor-driven rotating structure. At the same time, the coordinated work of the telescopic structure and the locking structure provides a strong locking force, effectively preventing the robot arm from accidentally moving or falling off during operation. In addition, the cooperation between the built-in sensor and the external artificial intelligence control device further improves the operation efficiency and safety, and solves the common defects of traditional robot arm locking devices such as low control accuracy and lack of locking force, which easily cause the robot arm to accidentally move or fall off during the operation process.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
