Embodiment Construction

[0040] The content of the present invention is described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0041] like Figure 1-Figure 3 As shown, the splined centering device includes fine-tuning screws and cooperating centering car parts and mirror mounts.

[0042] The outer wall of the centering car part is provided with a first spline structure, and the first spline structure is three first bosses evenly distributed along the circumference of the outer wall of the centering car part; the arc length of the first boss is the outer surface of the entire centering car part 1 / 12 of the circumference of the circle. The inner wall of the mirror seat is provided with a second spline structure, and the second spline structure is three second bosses evenly distributed along the circumference of the inner wall of the mirror seat; the middle part of the mirror seat between the adjacent second bosses is provided with an adjusting screw ...

Abstract

According to the spline type centering device and the adjusting method adopting the centering device, the technical problem that an existing centering technology cannot meet the increasingly-improved assembling precision requirement is solved, a first spline structure is additionally arranged on the outer circle of a centering turning part, a second spline structure is additionally arranged on the inner circle of a mirror base, and therefore the assembling precision is improved. After the centering lathe part is installed, switching between the precision matching mode and the fine adjustment mode of the centering lathe part and the mirror base spline can be achieved by rotating the centering lathe part. And after the fine adjustment mode is adjusted, the position of the centering vehicle part is adjusted through the fine adjustment fastener, the image quality of the product is improved, and the assembly precision is met.

Description

technical field [0001] The invention belongs to the technical field of opto-mechanical assembly and adjustment, and in particular relates to a spline type centering car part and an adjustment method using the centering car part. Background technique [0002] The process of the centering car is mainly used to ensure that after the centering optical lens is installed in the structural frame, the optical axis of the lens is coaxial with the outer circle of the frame, and is perpendicular to the reference end face of the frame. As a mature process, centering car has been widely used in the opto-mechanical design process of cameras, infrared cameras and visible light TVs. [0003] At present, the quality requirements of optoelectronic products are getting higher and higher, that is, the products are required to have clearer image quality, higher optical resolution and better optical axis consistency, so more stringent requirements are placed on the installation accuracy of optica...
