Problems solved by technology

[0006] 1. Due to the high height of the micrometer eyepiece of the objective lens adjustment device, there are certain difficulties in the assembly and adjustment of the personnel involved in the assembly.
[0007] 2. When observing the reflective imaging of the photosensitive surface of the photoelectric receiver in the micrometer eyepiece, long-term observation is easy to visual fatigue, which will easily lead to a decrease in the accuracy of assembly and adjustment and low labor efficiency, and there will be damage to the eyesight of the assembly personnel and Poor working environment
[0008] 3. The position of the exit pupil (eye point) of the objective lens adjustment device is far from the installation position of the photoelectric receiver on the objective lens adjustment device. When adjusting the optical axis of the photoelectric receiver and the coaxiality of the mechanical axis, it is impossible to achieve simultaneous Observation and simultaneous adjustment
Therefore, in actual operation, it is necessary to repeatedly press the line to measure the reading, remove and adjust the screw stop, and then install the repeated work process of the line pressing reading measurement. There is a phenomenon of cumbersome operation, time-consuming and laborious, resulting in low work efficiency and affecting photoelectric reception. The speed of device installation and adjustment is difficult to guarantee the shift production

Abstract

The invention relates to a visual adjusting device for debugging a photoelectric receiver optical shaft and a mechanical shaft, which comprises an objective lens timing device. The visual adjusting device is characterized by further comprising an image observer and an LED displayer; one end of the image observer is fixedly connected with the objective lens timing device through a connector, and the other end thereof is electrically connected with the LED displayer through a power interface. The visual adjusting device has the advantages of the visualization of coaxial mounting and debugging ofthe optical shaft and the mechanical shaft of an optical spare part in the photoelectric receiver, reducing the vision impairment of regulators by light intensity, improving the labor working environment, improving the adjusting efficiency, and lightning the labor intensity of the adjusting staffs. Besides, the visual adjusting device reaches the purpose of improving both working efficiency and economic benefit.

Description

technical field [0001] The invention relates to an adjustment device, in particular to a visual adjustment device for adjusting the optical axis and mechanical axis of a photoelectric receiver. Background technique [0002] The photoelectric receiver is a device that can convert optical radiation energy into electrical signals, so as to obtain the laser echo signal emitted by the laser irradiator after diffuse reflection of the destroyed target, and complete the stabilization, search and tracking of the destroyed target. [0003] At present, the domestic photoelectric receiver is composed of an objective lens system composed of multiple sets of optical lenses and a photoelectric detector. The accuracy of the focal length of the objective lens is realized by adjusting the dispersion circle, and then the optical axis of the photoelectric receiver ( The connection between the centers of all the lenses that make up the optical system) and the coaxiality of the mechanical axis (r...
