Problems solved by technology
The traditional mechanical support structure has a shafting structure, which has the disadvantages of large inertia and frictional moment of the shafting structure, which leads to serious nonlinearity in the control system, slow system response, and low control accuracy.
The existing optoelectronic system has high requirements on frequency response characteristics, and requires the system to be frictionless, small in size and compact in structure, while the traditional rotating mechanism is expensive, large in size, complex in equipment and difficult to maintain

The invention relates to a two-axis rotating mechanism based on a flexing rod and a flexible ring. The base of the mechanism is fixedly connected with coils parts of four linear voice coil motors. Twoopposite linear voice coil motors are parallel in direction. The directions of two adjacent linear voice coil motors are perpendicular to each other. A load bracket is fixedly connected with the magnetic steel parts of four linear voice coil motors. The edge part of the flexible ring is pressed and fixed on the base, and the central part is fixedly connected with the load bracket. The transitionpart between the edge part and the center part is suspended. The flexible ring is surrounded by four linear voice coil motors. The flexing rod is inserted into the central via hole of the flexible ring. The bottom of the flexing rod is fixedly connected with the base, and the upper part is fixedly connected with the load bracket.
Description
technical field [0001] The invention belongs to the technical field of photoelectric platform mechanical design, and relates to a two-axis rotating mechanism based on a flexible rod and a flexible ring. Background technique [0002] The two-axis rotation mechanism enables precise, fast, low-cross-coupling two-axis rotation. The design of the traditional two-axis rotating mechanism is based on the rigid mechanism, and the movement is realized by the combination of the kinematic pair and the rigid rod. There are friction and gaps in the rigid mechanism, and it needs to be lubricated, so it cannot adapt to extreme environments, and the precision of rotation is easily affected by external disturbances. In recent years, some rotating mechanism designs based on compliant mechanisms have emerged, mainly relying on elastic deformation of flexible structures to achieve movement, but they cannot solve the influence of cross-coupling of the two axes, which increases the difficulty of ...
