Industrial robots in production generally need to be equipped with peripheral equipment in addition to their own performance characteristics, such as rotary tables for turning workpieces and moving tables for moving workpieces. The motion and position control of these peripheral devices need to be matched with the industrial robot and require corresponding accuracy. Generally, robot motion axes can be divided into robot axes, base axes and tooling axes according to their functions, and base axes and tooling axes are collectively called external axes.
Six-axis industrial robots are six-joint industrial robots commonly used in actual production. Six-axis robot arm, six-joint robot arm, six-axis robot arm, robot arm, etc. are its names, and industrial robots are generally referred to as four-axis, five-axis, and six-axis robots. The joint structure of each robot will be different. The following explains which six axes of the six-axis robot are and what they do.
The first axis: the body rotation axis, which is the part connected to the base, is a larger axis for the industrial robot to carry, which can rotate the action left and right, similar to the way of action of the grinding wheel, and it carries the weight of the whole robot and the large swing of the robot left and right horizontally.
The second axis: the front and rear swing axis of the main arm is the core connection position of the robot parts, which is used to carry the top and bottom, and is an important axis to control the front and rear swing and expansion of the robot.
Third axis: The third axis is an axis that controls the front and rear swing of the robot. The action function of the third axis is similar to that of the second axis, which also controls the swing function of the robot up and down, and the action of the third axis position is relatively small, but this is also the basis for the long arm span of the six-axis robot.
The fourth axis: it is the part of the industrial robot above the position of the circular tube axis, which can be freely rotated, that is, a cylinder rotation just inside the limit of an extra cable. The fourth axis is an axis that controls the upper arm part of the 180° free rotation, which is equivalent to the human small arm.
The fifth axis: the fifth axis is very important, when you almost adjust the position, you have to accurately position to the product, you have to use the fifth axis, this position is quite a human arm in the wrist joint, can be up and down a small movement, is the product grasp after the product or fixed tool can be made to flip the action,.
Sixth axis: the end of the rotary axis, is in the back of the joint to fine-tune the position; when you position the fifth axis to the product, the need for some minor changes, you need to use the sixth axis, the sixth axis is equivalent to a horizontal 360 ° rotation of a turntable. It can be more precisely positioned to the product.
