Mechanical Arm Free Sample  Robotic arms are the most widely used automatic mechanical devices in the field of robotics technology, seen in manufacturing, medical care, entertainment services, the military, semiconductor manufacturing, and space exploration. Despite their different shapes, they all have one feature in common, namely, they can receive instructions and accurately locate a specific point in three-dimensional (or two-dimensional) space for operations.
Arms generally have 3 movements: stretching, twisting, and lifting. The rotational and lifting movements are carried out by the horizontal arm and the production column. The basic function of the arm is to move the gripper to the desired position and bear the maximum weight of the gripper for gripping the workpiece, as well as the weight of the arm itself.
Folded Composition
The arm consists of the following parts:
(1) Moving elements. Such as oil cylinders, cylinders, racks, cams, etc. are the components that drive the movement of the arm.
(2) Guiding device. This is to ensure the correct orientation of the arm and to resist bending and twisting moments due to the weight of the workpiece.
(3) Arm. Plays the role of connecting and resisting external forces. Components in the arm, such as cylinders, guide rods, controls, etc., are mounted on the arm.
In addition, according to the movement and work requirements of the manipulator, such as pipes, cooling devices, stroke positioning devices and automatic detection devices, they are generally installed in the arm. Therefore, the structure, working range, bearing capacity and accuracy of the action of the arm directly affect the performance of the manipulator.Mechanical Arm Free Sample
