Description
Technical Field
[0001] The present invention relates to the field of mechanical arm mounting structures, and in particular to a mechanical arm mounting structure. Background Art
[0002] A robotic arm is a complex system with high precision, multiple inputs and outputs, high nonlinearity, and strong coupling. For different tasks, it is necessary to plan the motion trajectory of the robotic arm's joint space, thereby cascading to form the end posture. When using the robotic arm, it needs to be installed in a fixed position to prevent the robotic arm from shaking during operation.
[0003] The common robotic arm installation structure only includes a tightening function, which can fix the position of the robotic arm, but lacks the functions of anti-rotation and convenient loading and unloading of goods. It is impossible to guarantee the tightening force of the tightening plate and the convenience of loading and unloading of the robotic arm. The threaded rod is prone to rotation, causing the tightening plate to move away from the fixed block. The robotic arm is also prone to being too heavy, resulting in inconvenience in carrying during installation and disassembly, affecting the installation stability and the convenience of loading and unloading of goods.
[0004] Therefore, in view of the fact that the above-mentioned robot arm mounting structure lacks the functions of anti-rotation and convenient loading and unloading of goods, a robot arm mounting structure can be designed. The limit rod is pushed upward by the thrust of the spring until the top of the limit rod is inserted into the inside of the limit hole. At this time, the lower half of the limit rod is left inside the telescopic groove to fix the position of the handwheel. When transporting the robot arm body up and down, it is placed on the top of the concave lifting plate, and then the motor drives the lead screw to rotate. The lead screw drives the robot arm body to move up and down through the concave lifting plate. When loading and unloading of goods is required, the robot arm body is pushed to move left and right. At this time, the rotating shaft rotates through the friction between the robot arm body and it, thereby making it more convenient to load and unload the robot arm body. Summary of the invention
[0005] In order to overcome the common robot arm installation structure, the functions of anti-rotation and convenient loading and unloading of goods are lacking, the tight resistance of the abutment plate and the convenience of loading and unloading of goods by the robot arm cannot be guaranteed, and the threaded rod is prone to rotation, causing the tight abutment plate to move away from the fixed block, and the weight of the robot arm is prone to being too heavy, resulting in inconvenience in carrying during installation and disassembly, affecting the installation stability and the convenience of loading and unloading of goods.

[0007] Preferably, the limit rod is pushed upward by the thrust of the spring until the top of the limit rod is inserted into the inside of the limit hole, and the lower half of the limit rod is then retained in the telescopic groove, so as to fix the position of the handwheel. When the mechanical arm body is transported up and down, it is placed on the top of the concave lifting plate, and then the motor drives the screw rod to rotate, and the screw rod drives the mechanical arm body to move up and down through the concave lifting plate. When loading and unloading goods is needed, the mechanical arm body is pushed to move left and right. At this time, the rotating shaft rotates through the friction force between the mechanical arm body and it, thereby making it more convenient to load and unload goods to the mechanical arm body, so as to solve the common mechanical arm installation structure, which only includes a tight resistance function and can fix the position of the mechanical arm, but lacks the functions of anti-rotation and convenient loading and unloading, and cannot guarantee the tight resistance of the tight resistance plate and the convenience of loading and unloading goods by the mechanical arm. It is easy for the threaded rod to rotate, causing the tight resistance plate to move away from the fixed block, and it is easy for the weight of the mechanical arm to be too heavy, resulting in inconvenience in carrying during installation and disassembly, affecting the installation stability and the convenience of loading and unloading goods.

[0017] Beneficial effects of the present invention: 1. The limit rod is pushed upward by the thrust of the spring until the top of the limit rod is inserted into the inside of the limit hole. At this time, the lower half of the limit rod is placed inside the telescopic slot to fix the position of the hand wheel. This solves the problem that the common mechanical arm installation structure only includes a tight contact function, which can fix the position of the mechanical arm, but lacks an anti-rotation function and cannot guarantee the tight contact force of the tight contact plate. The threaded rod is prone to rotation, causing the tight contact plate to move away from the fixed block, affecting the installation stability. 2. When transporting the robot arm body up and down, place it on the top of the concave lifting plate, and then drive the screw rod to rotate through the motor. The screw rod drives the robot arm body to move up and down through the concave lifting plate. When loading and unloading goods is required, the robot arm body is pushed to move left and right. At this time, the rotating shaft rotates through the friction between the robot arm body and it, thereby making it more convenient to load and unload the robot arm body. In order to solve the common robot arm installation structure, it only includes a tight-fitting function, which can fix the position of the robot arm, but lacks the function of convenient loading and unloading goods, and cannot guarantee the convenience of loading and unloading goods by the robot arm. It is easy for the robot arm to be too heavy, resulting in inconvenient transportation during installation and disassembly, affecting the convenience of loading and unloading goods.
