Abstract
The invention relates to a four-axis two-dimensional pointing mechanism, belonging to the technical field of a space motion mechanism. The single four-axis two-dimensional pointing mechanism comprises a cantilever beam, a motor, an output gear shaft, an angle sensor, an azimuth support, a pitching speed reducer, a load, an azimuth rotation shaft and a pitching rotation shaft. The motor, the output gear shaft, the angle sensor and the azimuth support are fixedly connected to the cantilever beam in sequence; the pitching speed reducer is fixedly connected to the azimuth support; the load is arranged on the azimuth support through the azimuth rotation shaft; the pitching speed reducer drives the load to rotate around the azimuth rotation shaft at an angle of 0-180 degrees; and the cantilever beam drives the azimuth support to rotate around the azimuth rotation shaft at an angle of 0-180 degrees through the motor and the output gear shaft. The cantilever beam and the pitching speed reducer are integrated into a whole, thus the volume and the weight of the four-axis two-dimensional pointing mechanism are reduced, the installation space of a cantilever beam pointing mechanism is saved, and the use filed of the cantilever beam pointing mechanism is expanded.
Description
Technical field
The present invention relates to a kind of four two-dimentional directing mechanisms, belong to space motion mechanism technical field.
Background technology
Four two-dimentional directing mechanisms of cantilever beam installation form commonly used mainly partly are made up of cantilever beam, retarder, swinging mounting, rotation load etc. at present.It is bigger that the subject matter that exists is that parts such as cantilever beam, retarder take up room, and simultaneously, mechanism's sole mass is bigger, is not suitable for the less occasion of bulk and requirements for quality, such as using in the Aeronautics and Astronautics device.
Summary of the invention
The objective of the invention is to propose a kind of four two-dimentional directing mechanisms for the installation that solves existing four two-dimentional directing mechanisms in small space, the problem of using difficulty, this directing mechanism makes load can point to any one interior direction of three dimensional space.
The objective of the invention is to be achieved through the following technical solutions.
A kind of four two-dimentional directing mechanisms of the present invention, this directing mechanism are four two-dimentional directing mechanisms at small space internal cantilever beam installation form.Directing mechanism can use by separate unit, and then the load direction of directing mechanism can change in orientation and 180 ° of angular ranges of pitch orientation; Directing mechanism also can match use, promptly install by two identical directing mechanism dos-s, the load direction of a directing mechanism changes in orientation and 0～180 ° of angular range of pitching, the load direction of another directing mechanism changes in orientation and 180 °～360 ° angular ranges of pitching, realizes any one direction in the load sensing three dimensional space.
Four two-dimentional directing mechanisms of separate unit comprise cantilever beam, motor, output gear shaft, angular transducer, orientation support, pitching retarder, load, direction rotating shaft and pitching rotating shaft; Motor, output gear shaft, angular transducer and orientation support are fixedly connected sequentially on cantilever beam, the pitching retarder is fixedly connected on the orientation support, load is installed on the orientation support by the pitching rotating shaft, the pitching retarder drives load and rotates around the pitching rotating shaft, slewing area is 0～180 °, cantilever beam drives the orientation support by motor, output gear shaft and rotates 0～180 ° of slewing area around direction rotating shaft.
