Two-dimension angular adjustment mechanism with high bearing capacity

Abstract

The invention discloses a two-dimension angular adjustment mechanism with a high bearing capacity, wherein the two-dimension angular adjustment mechanism with the high bearing capacity is suitable for top surface center installation or eccentric installation. The two-dimension angular adjustment mechanism with the high bearing capacity comprises a top plate, a bottom plate, a first supporting pillar adjusting mechanism, a second supporting pillar adjusting mechanism, a supporting pillar, a locating steel ball, a first limiting mechanism, a second limiting mechanism and a stop dog. According to the two-dimension angular adjustment mechanism with the high bearing capacity, the relative distance between the top plate and the bottom plate is changed by means of adjusting the first supporting pillar adjusting mechanism and the second supporting pillar adjusting mechanism, so that the pitching function, the deflection angle adjustment function and the locking function of the whole mechanism are achieved. The two-dimension angular adjustment mechanism with the high bearing capacity is suitable for bare engine elements with a large mass and suitable for top surface center installation or eccentric installation, and no counter weight structure is needed for two-dimension angular adjustment. The two-dimension angular adjustment mechanism with the high bearing capacity is simple in structure, convenient to operate, and stable, reliable and compact in overall structure.

Description

technical field [0001] The invention relates to a two-dimensional adjustment mechanism, in particular to a large-load two-dimensional angle adjustment mechanism installed centrally or eccentrically on the top surface. Background technique [0002] In the experiment of optical precision machinery, it is required to adjust the two-dimensional angles of pitch and yaw of the optical mechanical components in many occasions. In the mechanism, three steel balls are generally used in contact with the top plate of the adjustment frame, one of which acts as a fulcrum, and two of them adjust. This structure generally uses the tension of the spring and the fulcrum of the micrometer head and steel balls to connect the top plate and the steel ball. The bottom plate is relatively fixed. This structure is only suitable for installing optomechanical components at the center of the top surface of the mechanism. For installations that need to be installed at an eccentric position on the top su...

[0002] In the experiment of optical precision machinery, it is required to adjust the two-dimensional angles of pitch and yaw of the optical mechanical components in many occasions. In the mechanism, three steel balls are generally used in contact with the top plate of the adjustment frame, one of which acts as a fulcrum, and two of them adjust. This structure generally uses the tension of the spring and the fulcrum of the micrometer head and steel balls to connect the top plate and the steel ball. The bottom plate is relatively fixed. This structure is only suitable for installing optomechanical components at the center of the top surface of the mechanism. For installations that need to be installed at an eccentric position on the top surface, especially when the mass of the optomechanical components is large, when using this adjustment mechanism, For stability, the top plate and the bottom plate are relatively fixed, which can only be achieved by adding additional counterweights, which increases the cost and poor stability
