Embodiment 1

[0017] Such as figure 1 As shown, the precision motion pair in the electric adjustment frame,

[0018] It includes a support frame 1, an adjustment device 2 fixed on both sides of the support frame 1, and a mirror frame 3 fixed on the bottom of the support frame 1 through a universal ball head; the adjustment device 2 includes a stepping motor 4 and a stepping motor 4 The connected housing 5, which is a cavity structure, further includes a telescopic coupling 7 arranged in the cavity structure of the housing 5 and connected to the output shaft 6 of the stepping motor 4, and the other end of the telescopic coupling 7 The connected precision screw 8 also includes positioning seats 9 on the upper surface of the two ends of the lens frame 3, and the ends of the precision screw 8 fall on the positioning seats 9.

[0019] In this embodiment, one end of the telescopic coupling 7 is connected to the precision screw 8, and the other end of the telescopic coupling 7 is connected to the stepp...

Embodiment 2

[0021] In this embodiment, on the basis of Embodiment 1, the telescopic coupling 7 is a bellows coupling.

[0022] In this embodiment, the use of the welded bellows coupling can greatly reduce the return difference caused by the electric adjustment frame during the adjustment process and keep the return difference stable.

Embodiment 3

[0024] Such as figure 1 As shown, this embodiment is based on Embodiment 1 or Embodiment 2. The positioning seat 9 is a V-shaped positioning seat, and further includes a protrusion 10 arranged at the end of the precision screw 8 and a cemented carbide hemisphere The upper surface of 11 is provided with a groove corresponding to the bump 10, and the bump 10 is embedded in the groove; the lower surface of the cemented carbide hemisphere 11 falls in the V-shaped positioning seat, and the convex block 10 The diameter is smaller than the diameter of the precision screw 8, wherein the diameter of the end face of the cemented carbide hemisphere 11 is equal to the diameter of the precision screw 8.

[0025] In this embodiment, the end of the precision screw 8 is provided with a bump 10, and the cemented carbide hemisphere 11 is embedded at the end of the precision screw 8. Since the diameter of the cemented carbide hemisphere 11 is equal to the diameter of the precision screw 8, the hard ...

Abstract

The present invention describes the precision kinematic pair in the electric adjustment frame, which includes a support frame, an adjustment device fixed on both sides of the support frame, and a mirror frame fixed on the bottom of the support frame through a universal ball head; the adjustment device includes a stepping motor 1. The casing connected with the stepping motor, the casing is a cavity structure, and also includes a telescopic coupling arranged in the cavity structure of the casing and connected with the output shaft of the stepping motor and a telescopic coupling connected with the other end of the telescopic coupling The precision screw also includes positioning seats on the upper surfaces of both ends of the frame, and the ends of the precision screw fall on the positioning seats. In the present invention, when the precision screw moves up and down along its axis under the action of the stepping motor, the mirror frame can be fine-tuned. The use of welded bellows coupling can greatly reduce the return difference generated by the electric adjustment frame during the adjustment process and keep the return difference stable.

Description

Technical field [0001] The invention relates to an electric adjustment frame, in particular to a precision movement pair in the electric adjustment frame. Background technique [0002] In the optical system, when adjusting the position of large-aperture optical elements, the adjustment frame is required to have extremely high resolution, but the existing technology mostly heats the material of the contact pair to increase its hardness to ensure the adjustment The frame has a certain resolution. But this makes the production cost higher and the operation troublesome. Summary of the invention [0003] In order to solve the defect of low resolution of the electric adjustment frame, the present invention provides a precise movement pair in the electric adjustment frame. [0004] The technical scheme of the present invention is as follows: [0005] The precision motion pair in the electric adjustment frame includes a support frame, adjustment devices fixed on both sides of the support f...
