Support fine-tuning device for optical axis alignment of front mirror

Abstract

The invention discloses a support fine-tuning device applied to pre lens optical axis alignment. The device is formed by fixedly connecting a leveling platform, a lifting component and an angle fine-tuning component from bottom to top. The leveling platform uses a three point leveling principle to realize rapid leveling. The lifting component uses a nut screw mechanism with limiting and a tension spring to realize smooth and continuous lifting. A pipe seat in the angle fine-tuning component is fixedly connected with a ball pin. A base is fixedly connected with a ball pin seat. The ball pin and the ball pin seat form a spherical pair. A limiting shaft on the ball pin and a rectangular groove on the base form a sliding pair. When in use, a pre lens is arranged in the pipe seat. By rotating a pitch wheel on the pipe seat, fine-tuning and locking can be carried out on the pitch angle of the pre lens. By rotating an orientation wheel on the base, the pipe seat is pushed to realize fine-tuning and locking of the orientation angle of the pre lens, thus a pre lens optical axis is accurately aligned with a tested product. According to the invention, the problems of support and fine-tuning of the pre lens are solved, and the device has the characteristics of simple structure, convenient erection, small occupied space, convenient adjusting and the like.

Description

technical field [0001] The invention belongs to the field of process devices, and mainly relates to a process device used when the optical axis is aligned, in particular to a supporting fine-tuning process device for adjusting the angle and height when the optical axis of a front mirror is aligned with a product to be tested. Background technique [0002] In optoelectronic systems, it is often required that the optical axis of the system be parallel to the reference. During the optical-mechanical adjustment of the photoelectric system, front mirrors are often used to build various optical paths to adjust and test the optical axis of the system. Due to the different structural dimensions, shapes, and optical paths of various photoelectric systems, at this time, it is necessary to use a fine-tuning device to adjust the angle and height of the front mirror according to the actual position of the photoelectric system under test, so that the optical axis of the front mirror is in...

AI Technical Summary

Problems solved by technology

Ordinary fine-tuning devices have a complex structure, high manufacturing costs, and it is difficult to adapt the angle and height. The combination temporarily built with ordinary devices is huge in size, unstable in connection, and inconvenient to move

Therefore, ordinary simple devices are difficult to solve the problems of convenient installation, alignment adjustment and safety of photoelectric systems during calibration and testing

[0003] Chinese patent 201120399627 discloses "an angle fine-tuning device". This device mainly uses a worm gear and a worm pair as an angle adjustment mechanism. Due to the use of a worm gear, the structure is complicated, the manufacturing is difficult, the cost is high, and it can only be wound around one Axis for angle adjustment, not two-dimensional angle adjustment

Chinese patent 200910041514 discloses a "manual fine-tuning mechanism". This device adopts a spherical pair structure, which can realize the adjustment of the rotation angle, but its function is relatively single, it does not have a lifting function, and the height direction cannot be adjusted; in addition, because it has three rotating degrees of freedom, so too many degrees of freedom make the adjustment process complicated and difficult to align quickly and accurately
