As an embodiment, as shown in fig. 8 (a), a through hole is formed at a middle position of the rotating bracket, and a chamfer is formed at one end of the through hole; the Z-direction rotating mechanism comprises a dial, a plurality of third steel balls are circumferentially arranged on one surface of the dial facing the through hole, and the third steel balls are in tangential contact with the chamfer surface.
Specifically, the size of the chamfer surface is determined according to the size of the third steel ball and the diameter of the dial, so that the clearance between the dial and the through hole of the selection bracket is 0.05-0.1mm after the dial is assembled with the third steel ball.
Specifically, the dial is of a flange structure, and a plurality of third steel balls are circumferentially arranged on the right-angle surface of the flange plate so as to be in tangential contact with the right-angle surface on the through hole of the rotating support. The dial plate assembled with the third steel balls is arranged in the through hole of the rotary support, the third steel balls are tangential to the dial plate and the chamfer surface, and the rotary central axis of the dial plate is prevented from shifting in the rotary process by the double positioning mode of the through hole and the circle of third steel balls, so that the stability of the device is improved.
As shown in fig. 8 (b), a counter bore is formed at the other end of the through hole opposite to the chamfer surface, an elastic gasket is placed in the counter bore, and a plurality of fourth steel balls are circumferentially arranged on the end surface of the elastic gasket.
Specifically, a plurality of small holes are formed in the circumferential direction of the end face of the elastic gasket, and fourth steel balls are arranged in the small holes. The fourth steel balls rotate in the elastic gasket and are matched with the third steel balls, friction born by rotation adjustment is reduced, and smooth rotation of the dial is ensured.
The inside packing ring and the tail ring of installing of calibrated scale, packing ring and tail ring threaded connection are used for fixed lens. The prior lenses are fixed through side mounting, at the moment, the diameter and thickness of the lenses have larger influence on the assembly process, the mounting surface of the lenses is easy to be unparallel with the bracket, and after the tail ring fixing mode is adopted, the stress of the lenses is relatively uniform, so that the angle deviation can not occur.
The elastic gasket and the dial are fixed in the through hole through the tailstock, and the tailstock is in threaded connection with the dial.
Specifically, the inner ring of the tailstock is provided with an internal thread which is matched with the external thread of the dial. The tailstock is fixedly connected with the dial by the matching of the internal thread and the external thread.
Specifically, screw fixing holes are formed in the side face of the tailstock and used for adjusting tightness of the dial. When the dial is not smooth to rotate, the pretightening force of the fastening screw on the tailstock is reduced, the dial is smooth to rotate by rotating the fastening screw, and then the fastening screw is locked, so that the installation and fixation of the tailstock are completed. After the installation is completed, the tailstock and the dial as a whole rotate together 360 degrees around the rotating bracket.
For example, if the tailstock is screwed with the screw of the dial, the dial is difficult to rotate, the screw on the side face is adjusted, the pretightening force is reduced until the dial is easy to rotate, and on the basis, the screw on the side face is locked again, so that the installation of the tailstock is completed.
Further, the side of calibrated scale is equipped with calibrated scale set screw hole, when having adjusted required polarization state, perhaps reached required transmissivity after, makes the calibrated scale unable rotation through this screw hole locking screw, guarantees can not lead to the error because of the calibrated scale rotation in the follow-up operation.
As shown in fig. 7, the end face of the dial is provided with 0-360 ° mark lines, wherein the 0 scale line is marked with an optical axis for alignment of the optical axes of the polarization type optical components. And alignment scale marks are marked on the rotary support. The alignment graduation marks are used for aligning with the mark lines, so that the rotation angle can be accurately observed during rotation.
