Problems solved by technology

[0008] The purpose of the present invention is to overcome the reliance of the current prism assembly on the experience and feel of personnel during the assembly process, and the interference fit problem caused by the excessively large matching contact surface between the right-angled surface of the prism frame and the aiming prism, and at the same time consider the parts brought by the material of the prism frame Processability, providing a new prism component and its assembly method

Embodiment Construction

[0054] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in detail, but should be understood that protection scope of the present invention is not limited by specific embodiment.

[0055] A prism assembly such as figure 1 As shown, the prism mounting frame 1 is included, the bottom of the bottom plate of the prism mounting frame 1 is provided with a flange 9, the bottom plate of the prism mounting frame 1 and the flange 9 overlap each other and form an integral structure, and the integral structure formed by the prism mounting frame 1 bottom plate and the flange 9 The structure increases the rigidity and stability of the prism mounting frame, and the overall thickness of the bottom plate of the prism mounting frame 1 and the flange 9 is designed to be 5 mm to 6 mm. like figure 2 As shown, on both sides of the right-angled surface of the prism mounting bracket 1, a boss 11 with an included angle of 90° is respectively ar...

Abstract

The invention particularly relates to a prism assembly and an assembling method thereof. The problems that an existing prism assembly depends on experience and hand feeling of personnel in the assembling process and interference is caused due to too large matching contact face between the right-angle face of a prism frame and an aiming prism are solved, and meanwhile the part machining manufacturability brought by the prism frame material is considered. The prism assembly comprises a prism installation frame; a flange is connected to the bottom of the prism installation frame; an aiming prism is placed on the right-angle face of the prism installation frame; first packing paper is placed on a boss on the right-angle face of the prism installation frame and serves as a combination isolation pad between the prism installation frame and the aiming prism; and a prism pressing plate is arranged on the side face of the aiming prism and fixed through a screw. The invention further provides an assembling method of the prism assembly.

Description

technical field [0001] The present invention relates to an optical device, in particular to a prism assembly, and also to an assembly method of the prism assembly. Background technique [0002] At present, known prism components are mainly divided into two categories: [0003] The first type of prism assembly is mainly made of iron-nickel-cobalt alloy 4J29 material into a V-shaped prism mount. Resin glue, and finally put the whole device into the oven to let the resin cure. [0004] The second type of prism assembly is mainly made of nickel-cobalt alloy 4J29 material or titanium alloy material into a V-shaped prism mounting frame. A rubber pad is added between the pressure plate and the aiming prism to stabilize the state of the prism. [0005] These two types of prism assemblies are the most commonly used prism assemblies at present, but there are various problems. [0006] The main problem of the first type of prism assembly is that when fixing the position of the pris...
