Problems solved by technology

[0006] The disadvantages of this product are: due to the combination of multiple single-function devices to achieve multi-dimensional adjustment, the overall structure size is relatively large, the weight is heavy, and the cost is high. application
[0015] However, due to the small diameter of the telescope prototype itself, the small space size, and limited structural rigidity, it is impossible to select a suitable 6-DOF combination product
The Stewart platform is too expensive and unavailable

Abstract

Disclosed is a six-DOF (six degrees of freedom) adjusting device for common spatial adjustment of a telescope. Any spatial object has six degrees of freedom, including linear motions along three spatial directions mutually orthogonal and rotational motions around the three spatial directions; the six degrees of freedom are mutually independent; the six degrees of freedom are sufficient to describing the position and attitude of any spatial object. A usual adjusting mechanism simply aims to achieve one or combination of the six degrees of freedom. Existing position-attitude adjusting devices include: a six-DOF adjusting device composed of single-dimensional adjusting mechanisms; and a Stewart adjusting platform; the existing position-attitude adjusting devices have the defects that a control system is complex, the price is high, and one common product costs tens of thousands of China Yuan.

Description

technical field [0001] The invention belongs to the technical scope of an adjustment mechanism, in particular to the structural field of a six-degree-of-freedom adjustment device for common space adjustment. Background technique [0002] Any space object has 6 degrees of freedom, these six degrees of freedom are linear movement along three mutually orthogonal spatial directions and rotation around these three directions, these six degrees of freedom are independent of each other, And these 6 degrees of freedom are enough to describe the position and attitude of any space object. [0003] The purpose to be achieved by the usual adjustment mechanism is nothing more than one or a combination of these six degrees of freedom. The current position and attitude adjustment devices are: [0004] 1. The six-degree-of-freedom adjustment is obtained by combining the single-dimensional adjustment mechanism; [0005] The single-degree-of-freedom adjustment mechanism has a one-dimension...
