Description

Camera sensor inclination angle adjusting device based on multi-motor thread transmission Technical Field The utility model belongs to the technical field of astronomical photography and precision imaging, and particularly relates to a camera sensor inclination angle adjusting device based on multi-motor screw drive. Background In astronomical photography and high precision imaging fields, the tilt angle of a CMOS/CCD image sensor of a camera is critical to the imaging quality. The sensor plane may be slightly tilted from the optical axis due to manufacturing errors, device assembly errors, or structural deformations of the imaging system. Such tilt angle may result in clear focus in the center of the picture, while the surrounding area may not reach an ideal focus state, thereby affecting the imaging quality. In astronomical photography, this problem is often manifested in that the star points at the edges of the picture show distortion, affecting the photographic effect. Currently, an inclination angle adjusting device of an astronomical camera sensor on the market depends on manual adjustment, and is commonly designed into a three-pushing three-pulling structure, namely three groups of pushing screws and three groups of pulling screws. However, the manual adjustment mode has the defects that firstly, the adjustment precision is low, the repeated positioning precision is poor, the adjustment stroke can be roughly estimated only through screw pitch and rotation angle, and the requirement of high precision is difficult to meet. Secondly, the operation is complex, the use is inconvenient, and particularly, the adjustment process is difficult in outdoor, insufficient light or extreme environments. Thirdly, remote control is not possible, and the manual adjustment mode is difficult to meet the automatic adjustment requirement for an unattended astronomical station or a remote observation station. Therefore, there is a need to develop an electromotive, high-precision, remotely controllable camera sensor tilt adjustment device to make up for the deficiencies of the prior art. Disclosure of Invention The utility model aims to overcome the defects of the prior art and provide a camera sensor inclination angle adjusting device based on multi-motor thread transmission. The utility model is realized by the following technical scheme. The utility model mainly comprises an A component and a B component. And the component B is provided with three driving motors which are distributed at equal intervals (120 degrees) along the circumference of the same diameter. And placing a female threaded hole with corresponding specification at a corresponding position on the component A. Three driving motors arranged on the component B respectively drive three threaded connecting shafts with male threads to be screwed into threaded holes on the component A. The driving motor drives the threaded connecting shaft to rotate so as to generate relative displacement between the component A and the component B. A pre-tightening mechanism is arranged between the component A and the component B and comprises a plurality of springs and screws, and the screws penetrate through the springs and are fixed in threaded holes of the component B so as to apply pre-tightening force to the component A and eliminate return difference and mechanical shaking in the threaded transmission process. The three driving motors can be controlled respectively and independently, and according to the principle of determining one surface at three points, the relative displacement and the inclination angle between the component A and the component B can be changed by controlling the driving motors respectively, so that the precise adjustment of the angle between the plane where the camera sensor is located and the optical axis of the optical system is realized. When the telescope is installed and used, the component A is connected to one side of the telescope by means of threads and the like. The B-part is connected to the camera side by means of threads or the like. The a-part and the B-part may exchange roles. The utility model has the beneficial effects of realizing the inclination adjustment of the electric camera sensor, and simultaneously has the characteristics of high positioning precision, good repeated positioning precision and the like. Because of the electric control, the tilt angle of the camera sensor can be remotely adjusted in a contactless way by connecting with computer equipment.
