Abstract

The invention discloses a busbar rotating structure for an optical grating adjusting rack. The busbar rotating structure comprises a supporting plate, a picture frame plate, a busbar rotation driving assembly and an annular connecting piece. The front end face of the supporting plate is fixedly connected with the annular connecting piece, the picture frame plate is movably connected with the annular connecting piece, and the lower end of the left end face or the lower end of the right end face of the supporting plate is fixedly connected with a strength bearing plate. The busbar rotation driving assembly is fixedly connected to the rear end face of the picture frame plate above the strength bearing plate. The busbar rotation driving assembly comprises a driving motor, a bellows coupling, a threaded rod and a locating plate. One coupling end of the bellows coupling is fixedly connected with an output shaft of the driving motor, and the other coupling end of the bellows coupling is fixedly connected with the threaded rod. The locating plate is provided with a threaded hole penetrating through the locating plate, the threaded rod penetrates through the threaded hole, and the end of the threaded rod is in close contact with the strength bearing plate under the self weight of the busbar rotation driving assembly and the self weight of the picture frame plate. The busbar rotating structure for the optical grating adjusting rack has the advantages of being high in regulation precision, high in speed and high in stability.
