Abstract
The utility model relates to a swivel table of photo-detectors, which is mainly characterized in that a U-shape frame thereof is a division structure with a left and a right supporting stands, and is connected with a directional panoramic table through fastening pieces, openings are arranged on the upper portion and the lower portion of a bin body of the detector, and a ball-shape structure is formed by an upper, a lower, a left and a right cambered surface sealing covers which are respectively arranged, and a servo-driving circuit and a control component are installed in an orientation axle box. The swivel table has reasonable structure design, good assembly technology, convenient maintenance, and is convenient to the adjustments of the position accuracies of the pitch axis and the direction axis of the detector, can guarantee the regression accuracy and the rotary accuracy, is beneficial for improving the accuracy of the system, can reduce the occupied area of the ship platform and can reduce the volume and the weight of the swivel table.
Description
Technical field
The utility model belongs to navigation Detection Techniques field, is a kind of photodetector turntable.
Background technology
In technique known, traditional photodetector turntable, its U-shaped frame that supports sphere detecting head portion generally adopts the bottom conjoined structure, and be positioned at adopting U-shaped frame inner chamber photodetector warehouse more before and after opening, photoelectric detector in warehouse after-opening place is in the past installed, thereby the installation of photodetector caused very burden, and the inner space utilization factor is low.In addition, rotating circuit board of control azimuth axle and relevant controlling partly are installed in the special switch board, and the servo-drive system with the azimuth axis in cable and the panoramic table links again.The major defect of this panoramic table is that the circuit control section separates installation with panoramic table, and the plane space that takies boat is big, brings inconvenience.Secondly, owing to add the position of related features of necessary strict guarantee panoramic table left and right sides supported hole in man-hour, thereby, increased processing cost thus to each member requirement on machining accuracy height, its pitching revolving member installation accuracy also can not get guaranteeing, influences the usability of detector.
The utility model content
The purpose of this utility model provides a kind of photodetector that can guarantee and returns precision and rotation precision, and compact conformation, volume are little, in light weight, the photodetector turntable that occupies little space.
Realize that the technical scheme that the purpose of this utility model is taked is: this turntable comprises detector warehouse, U-shaped frame, orientation panoramic table and orientation axle box, wherein, a branch body structure that is configured to about the U-shaped frame is served as reasons, and be connected with the orientation panoramic table by securing member, the upper and lower position of detector warehouse is provided with opening, and constitute chondritic by the upper and lower, left and right cambered surface capping that is provided with respectively, servo driving circuit board and control device are housed in the orientation axle box.
Described orientation panoramic table is provided with level meter.
The detector turntable of making according to such scheme, its reasonable in design, assembly process process is good, be convenient to maintenance, and be easy to the adjusting of detector pitch axis and azimuth axis positional precision, can guarantee to return precision and rotation precision, help improving the precision of system, and can reduce taking up room of boat platform, reduce the volume and weight of turntable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, photodetector turntable of the present utility model, this turntable comprises detector warehouse, U-shaped frame, orientation panoramic table and orientation axle box, wherein, the U-shaped frame branch body structure that left and right sides support 4,5 constitutes of serving as reasons, the detector warehouse is between left and right sides support 4,5, it is the chondritic (rear seal-cover is not shown in the figures) that constitutes by the upper and lower, left and right cambered surface capping 1,2,3,11,12 that is provided with respectively, guarantee that it has the windproof spherical shapes on the one hand, can strengthen simultaneously the spatial accommodation of sensitive detection parts, installation and maintenance are convenient.At the upper and lower position of detector warehouse opening is set, can make detector that bigger installing space is arranged, and can increase the device mounting capacity, improve installation effectiveness, simultaneously under the situation that reduces the member machining precision, can guarantee the installation accuracy of pitching rotating shaft and servomotor and speed measuring motor, and then improve the usability of detection system.Left and right sides support 4,5 is connected with orientation panoramic table 6 by securing member respectively, by the height of adjustment left and right sides support 4,5 and the position of left and right directions, can adjust supported hole spatially can move by trace, and can guarantee that optical axis can satisfy the displacement error of regulation (be not more than 1.8 ') in the pitch rotation process, can reduce the requirement on machining accuracy of member thus and save processing cost.Upper table surface at orientation panoramic table 6 is provided with level meter 7, its setting can suitably reduce the machining precision of panoramic table and azimuth axis, and guarantee after the assembling azimuth axis in the verticality of rotation process neutralization levels face so that guarantee the detector optical axis satisfies regulation in the azimuth rotation process displacement error value be not more than 1.8 ' scope in.In the space of orientation axle box 8 inherent installation position axles 9 and servomotor servo driving circuit board and control device 10 are housed, have replaced the switch board of special installation servo driving circuit and control device 10 thus, saved taking up room of boat platform.
Claims (2)
1, a kind of photodetector turntable, it comprises detector warehouse, U-shaped frame, orientation panoramic table and orientation axle box, it is characterized in that: a branch body structure that is configured to about the U-shaped frame is served as reasons, and be connected with the orientation panoramic table by securing member, the upper and lower position of detector warehouse is provided with opening, and constitute chondritic by the upper and lower, left and right cambered surface capping that is provided with respectively, servo driving circuit board and control device are housed in the orientation axle box.
2, photodetector turntable according to claim 1 is characterized in that: described orientation panoramic table is provided with level meter.
