FIG. 2 is an exploded view of the structure of the present invention;
fig. 3 is a schematic diagram of the assembled dichroic mirror according to the present invention.
Detailed Description
The technical solution of the present invention is described in detail and completely with reference to the accompanying drawings and the specific embodiments.
Referring to fig. 1 to 3, a dichroic mirror vertical fixing jig includes a support module 1, a lower positioning module 2, an upper pressing module 3, and a pressing module 4.
As shown in fig. 2, the supporting module includes a bottom plate 1.1, bevel supporting plates 1.2 disposed at the left and right sides of the bottom plate, and a limiting supporting plate 1.3 disposed at the rear of the bottom plate and located between the two bevel supporting plates.
Lower orientation module includes locating plate 2.1, and the locating plate is the wave form, and it has a plurality of most advanced wedge grooves 2.2 down and is used for placing the dichroic mirror, all is equipped with support column 2.3 at the both ends of locating plate, and specific every wedge groove all has two inclined planes, and the inclined plane contained angle is 90 degrees, and a dichroic mirror is placed on every inclined plane. As shown in fig. 1, the positioning plate is placed between the bevel edge supporting plates at the two sides, the left end and the right end of the positioning plate are fixed with the bevel edge supporting plates by screws, and the rear part of the positioning plate is abutted against the limiting supporting plates; the limiting support plate functions to limit the top position of the dichroic mirrors so that the dichroic mirrors are in a uniform state.
The top die includes top board 3.1, and the top board piece cup joints in the top of locating plate through support column 2.3, and the top board can follow the reference column and reciprocate and can freely take out, and the bottom surface shape of top board agrees with the locating plate and is used for cooperating the locating plate to compress tightly two dichroic mirror.
