What are the components of the mechanical arm and its general structure?

The arm is an important part of the manipulator's executive mechanism, and its function is to send objects to a given position, so the general manipulator has three degrees of freedom, namely, the expansion, left-right rotation and lifting (or pitching) movement of the arm. The left-right rotation and lifting movement of the arm are completed through the column, and various movements of the arm are usually realized by driving mechanisms (such as oil cylinders or cylinders) and various transmission mechanisms. The structure, working range, flexibility, arm strength and positioning accuracy of the arm directly affect the working performance of the manipulator, so the structure type of the arm must be designed according to the requirements of grasping weight, motion form, degree of freedom, motion speed and positioning accuracy of the manipulator.

According to the structure of the arm, there are single arm, double arm and suspension type.

According to the form of athletes' arms, there are linear motion, rotary motion, up-and-down swing and compound motion. Arms with different structural types and motion forms have different structures and components, so there are too many details to explain in detail here. Please understand!
