In production, industrial robots in addition to their own performance characteristics, generally also need to be equipped with peripheral equipment, such as rotating workpiece turntable, moving workpiece mobile platform. The motion and position control of these peripherals needs to be matched with industrial robots and requires corresponding precision. Generally speaking, the robot motion axis can be divided into robot axis, base axis and fixture axis according to its function. The base shaft and the tool shaft are collectively referred to as the outer shaft.
Six-axis industrial robot is a commonly used six-joint industrial robot in practical production. Six axis manipulator, six joint manipulator, six axis manipulator, manipulator and so on is its name. Industrial robots generally refer to four axis, five axis and six axis manipulator. Each robot will have a different joint structure. Now let's explain what are the six axes of a six-axis robot and what are their functions?
The first axis
The rotating shaft of the body is the part connecting the base, which is the shaft with large bearing capacity of the industrial robot. It can rotate left and right, similar to the action of a millstone. It carries the weight of the whole robot and the huge horizontal swing of the robot.
The second shaft
The front and back swing axis of the main arm is the core connection position of the robot components. It's used to connect the previous one to the next one. It is an important axis to control the robot's swing and expansion.
The third shaft
Triaxial is the first axis that controls the robot to swing back and forth. The motion function of three axis and two axis is similar, and it is also the function of controlling the robot to swing up and down. The three-axis position plays a relatively small role, but it is also the basis for the extension of the six-axis robot arm.
The fourth axis
It is part of the position of the tube shaft on the industrial robot and is free to rotate, that is, the rotation of the cylinder is limited by more cables inside. These four axes control the 180° free rotation of the upper arm, equivalent to the human forearm.
The fifth axis
The fifth axis is very important. When you almost reposition, you position the product accurately. You need to use the fifth axis. This position is equivalent to the wrist on the human arm and can be moved up and down in small areas. After the product is captured, the product can be turned or fixed tool action.
6 axis
The terminal rotation axis is the joint of the rear fine-tuning position; When you locate the fifth axis on the product and need to make some minor changes, you need to use the sixth axis, which is equivalent to a turntable that can rotate 360° horizontally. Can be more accurately targeted to the product
