Abstract

The invention relates to a five-degree-of-freedom pose adjustment mechanism and belongs to the electromechanical equipment field. The five-degree-of-freedom pose adjustment mechanism is composed of a lifting platform, a rotation platform, a rolling platform, a translation platform, a test bench base and a pitch platform. The five-degree-of-freedom pose adjustment mechanism of the invention is characterized in that the lifting mechanism comprises lifting driving motors, a lifting platform, couplings, lifting guide rail sliders and ball screws and is mainly used for carrying load and a variety of kinds of operating load; the lifting driving motors are connected with the couplings; the lifting platform is connected with the lifting guide rail sliders; the lifting platform is made of a stainless steel material; and the ball screws are connected with the lifting guide rail sliders through transmission nuts. With the five-degree-of-freedom pose adjustment mechanism of the invention adopted, the reliability and motion precision of the pose adjustment mechanism under a vacuum and low-temperature environment can be guaranteed.
