Problems solved by technology

Due to the limitation of system installation space, the requirements of system installation and adjustment status, the difficulty of mechanical structure design and the limitation of processing technology, the rotation center of the rotation degree of freedom of the existing adjustment structure and the optical center of the optical components cannot be coincident.
This will cause a difference between the actual mechanical adjustment amount and the expected value of the optical adjustment amount, which will affect the convergence speed of the optical system adjustment process, making the system adjustment process slow down or even diverge

Embodiment 1

[0017] Such as figure 1 , figure 2 with image 3 As shown, the apex translation compensation drive assembly includes a base plate 1, a support plate 2, a translation drive assembly 3, an arm plate 4, a load bearing plate 5, a guide rail plate 6 and a slide plate 7, and one end of the arm plate 4 is fixedly connected to The upper end of the support plate 2 and the other end of the hanging arm plate 4 are provided with an adjustment shaft 41, the end of the adjustment shaft 41 is connected with a rotating ball head 42, and the guide rail plate 6 is horizontally fixed on the base plate 1. Sliding plate 7 is movably connected on the top of guide rail plate 6, and the upper end surface of described sliding plate 7 is provided with the ball groove seat 71 that is used to accommodate rotating ball head 42, and described rotating ball head 42 is inserted in the ball groove seat 71, and the upper end surface of sliding plate 7 is fixed. Connected with a translation drive assembly 3,...

Embodiment 2

[0019] This embodiment is further defined as follows on the basis of Embodiment 1. It is characterized in that: the ball groove seat 71 is formed by an indentation on the upper end surface of the slide plate 7; Low secondary connection. If the rotating ball head 42 is divided into the upper part and the lower part by the lateral diameter, in order to avoid the rotating ball head 42 from breaking away from the ball groove seat 71 during adjustment, the open end of the ball groove seat 71 surrounding the rotating ball head 42 should be located at the top of the rotating ball head 42 area.

Embodiment 3

[0021] The present embodiment is further defined as follows on the basis of Embodiment 1, the guide rail plate 6 is provided with a slide bar 61, the lower end surface of the slide plate 7 is provided with a chute compatible with the slide bar 61, and the slide bar 61 is placed into the chute. In order to improve the stability of the relative movement between the slide plate 7 and the guide rail plate 6, more than two slide bars 61 can be provided on the guide rail plate 6, and the slide plate 7 is provided with chute corresponding to the number and position of the slide bars 61 .

The vertex translation compensation driving assembly has the advantages of being high in adjusting accuracy, rapid in adjusting speed and strong in stability.

Description

technical field [0001] The invention relates to the technical field of optical instruments and equipment, in particular to an apex translation compensation driving assembly. Background technique [0002] As a basic component of modern optical instruments, optical adjustment mounts are used to support optical components, adjust the direction of light beams, and realize rapid and accurate positioning of light beams. They are currently widely used in laboratories, optical equipment, and instruments. Due to the limitation of system installation space, the requirements of system installation and adjustment status, the difficulty of mechanical structure design and the limitation of processing technology, the rotation center of the rotation degree of freedom of the existing adjustment structure and the optical center of the optical components cannot be coincident. This will cause a difference between the actual mechanical adjustment amount and the expected value of the optical adju...
