A precision five-dimensional turntable

Abstract

The invention belongs to the technical field of precision optical application mechanical equipment, and discloses a precision five-dimensional turntable, which includes a vertical shaft system, a translation component and a pitch component; the vertical shaft system includes a refractor, a leveling support base, a torque motor, a bearing pressure The cover, the first stage, the box body and the azimuth fixed shaft, thrust ball bearing, azimuth rotation shaft, first angular contact ball bearing, and bearing distance ring arranged in the box body; the bottom of the box body is provided with a through hole, Both the box and the refractor are fixed on the leveling support base; the refractor is located in the through hole at the bottom of the box; the side wall of the box is provided with two through holes, and the two through holes are opposite to each other. The central axis passes through the refracting mirror; the present invention is a multi-degree-of-freedom optical application rotary table with stable operation, reasonable and compact structure layout, high connection strength and rigidity, and good manufacturing processability.

Description

technical field [0001] The invention belongs to the technical field of precision optical application mechanical equipment, and relates to a precision five-dimensional turntable, which can be applied to precision optical application mechanical equipment or other similar mechanical equipment. Background technique [0002] The precision turntable is an important non-standard equipment for testing inertial components and conducting physical simulation experiments. It is mainly used in the optical field as a common debugging device for controlling and adjusting optical components in optical experiments and optical instruments. Usually, the optical element is fixed on the platen of the optical turntable during use, and the tracking and adjustment of the parameters of the optical element is realized through the rotation, translation, and pitch of the optical turntable. [0003] The accuracy of the vertical axis system of the turntable and the adjustable degree of freedom of the wor...

Problems solved by technology

The first solution is not only complex in structure and large in size, but also has gaps in multi-stage deceleration and transmission, and the servo rigidity is low; although the second solution is simple in structure, it is larger in size and has disadvantages such as easy wear and slipping; the third solution Torque motors are used to directly drive the shaft system for positioning, and the positioning accuracy is not high only relying on the direct drive of the torque motor. For the turntable with large volume and mass, it is very difficult to realize the servo control
