Description

Technical Field

[0001] This utility model relates to an assembly platform for a prism and a fixture. Background Technology

[0002] A roof prism is a prism with two mutually perpendicular reflecting surfaces, called the roof surfaces. It allows for image rotation and reversal, as well as deflecting light rays by bending them 90°. Suitable for telescopes and any optical instrument requiring image flipping from the objective lens, opening the right side, or bending the image 90°.

[0003] A ridge prism is a special variant of a pentaprism. In addition to two ridge surfaces, it has multiple reflecting surfaces. During processing, the ridge prism needs to be fixed in a fixture so that the reflecting surfaces to be processed protrude from the fixture. However, some ridge prisms are difficult to position, making it difficult to unify the protrusion height of the reflecting surfaces to be processed, which affects the processing accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide an assembly platform for a prism and a fixture. The prism is a roof prism, which has two mutually perpendicular roof ridge surfaces and a first surface to be processed located at one end of the two roof ridge surfaces and perpendicular to the two roof ridge surfaces. The fixture has a through groove for receiving the roof ridge surface of the roof prism. The fixture includes a bottom surface, a front side perpendicular to the bottom surface, and a rear side parallel to the front side. The through groove extends from the front side to the rear side of the fixture. The assembly platform includes a platform body and a positioning plate. The platform body includes a horizontal... The fixture comprises a vertical platform and a longitudinal platform, the longitudinal platform standing vertically on the transverse platform; the bottom surface of the fixture abuts against the transverse platform, the positioning plate is fixed relative to the longitudinal platform, and the rear side of the fixture abuts against the positioning plate to create a gap between the rear side of the fixture and the longitudinal platform, the gap being used to allow the first surface to be processed of the ridge prism to protrude from the rear end of the through groove; the front side of the fixture is parallel to the first surface to be processed; the longitudinal platform is used to allow the first surface to be processed of the ridge prism to abut against, thereby limiting the height of the first surface to be processed protruding from the through groove.

[0005] The prism and fixture assembly platform of this utility model, through the cooperation of the platform body and positioning plate with the prism and fixture, can unify the height of the surface to be processed protruding outside the fixture, thus ensuring the accuracy of subsequent processing.

[0010] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0011] See appendix Figure 1-4 An assembly platform for a prism and a fixture, wherein the prism is a roof prism 4, the roof prism 4 having two mutually perpendicular roof ridge surfaces 44 and a first surface to be processed 41 located at one end of the two roof ridge surfaces 44 and perpendicular to the two roof ridge surfaces 44.

[0012] The fixture 3 is provided with a through groove 35 for accommodating the ridge surface 44 of the ridge prism 4. The fixture 3 includes a bottom surface 33, a front side surface 31 perpendicular to the bottom surface 33, and a rear side surface 32 parallel to the front side surface 31. The through groove 35 extends from the front side surface 31 to the rear side surface 32 of the fixture 3.

[0013] The assembly platform includes a platform body 1 and a positioning plate 2; the platform body 1 includes a horizontal platform 11 and a vertical platform 12, the vertical platform 12 standing vertically on the horizontal platform 11 in an L-shape.

[0014] The bottom surface 33 of the fixture 3 abuts against the transverse platform 11, the positioning plate 2 is fixed relative to the longitudinal platform 12, and the rear side surface 32 of the fixture 3 abuts against the positioning plate 2 to create a gap between the rear side surface 32 of the fixture 3 and the longitudinal platform 12. This gap allows the first surface 41 to be processed of the ridge prism 4 to protrude from the rear end of the through groove 35. The front side surface 31 of the fixture 3 is parallel to the first surface 41 to be processed; the longitudinal platform 12 is used to allow the first surface 41 to be processed of the ridge prism 4 to abut against, thereby limiting the height of the first surface 41 protruding from the through groove 35.

[0015] In this embodiment, the bottom side of the positioning plate 2 abuts against the transverse platform 11.

[0016] The positioning plate 2 is magnetically fixed to the longitudinal platform 12. The magnetic fixing method facilitates disassembly and assembly, and positioning plates 2 of different thicknesses can be replaced according to the required protrusion height of the surface to be processed of the ridge prism 4.

[0017] The ridge prism 4 also has a second surface 42 to be processed opposite to the tip of the ridge surface 44 and a third surface 43 to be processed connected to the second surface 42. The through groove 35 includes two groove walls 351, which respectively allow the two ridge surfaces 44 of the ridge prism 4 to abut and limit each other so that the second surface 42 and the third surface 43 protrude out of the through groove 35. The bottom surface 33 of the fixture 3 is parallel to the second surface 42 to be processed. The fixture 3 also includes an inclined section 34 connecting its rear side surface 32 and the bottom surface 33, which is parallel to the third surface 43 to be processed. Under the limitation of the through groove 35, the ridge surface 44 of the ridge prism 4 can fix the second surface 42 to be processed and the third surface 43 to be processed at the same height outside the fixture 3.

[0018] The through slots 35 are provided in multiple ways, and each through slot 35 is distributed at intervals along the length direction of the fixture 3, which can position and process multiple prisms at one time, thereby improving processing efficiency.

[0019] The bottom surface 33, front side surface 31, and inclined section 34 of the fixture 3 are used to abut against different processing platforms to process the first surface to be processed 41, the second surface to be processed 42, and the third surface to be processed 43, respectively. The bottom surface 33, front side surface 31, and inclined section 34 of the fixture 3 are provided with grooves 311 for engaging and positioning with protrusions on the processing platform. The grooves 311 extend along the length direction of the fixture 3.

[0020] When in use, first place the jig 3 on the assembly platform, so that the bottom surface 33 of the jig 3 abuts against the horizontal platform 11, and the rear side 32 of the jig 3 abuts against the positioning plate 2.

[0021] Then, place the ridge surface 44 of the ridge prism 4 downward into the through groove 35 of the fixture 3, and make the first surface 41 to be processed of the ridge prism 4 abut against the longitudinal platform 12; after the ridge surface 44 and the groove wall 351 of the through groove 35 are fixed with wax, the prism and fixture 3 can be removed.

[0022] During subsequent processing, the bottom surface 33, the front side surface 31, and the oblique section 34 of the fixture 3 are used to fit and fix with different processing platforms, so that the surface to be processed parallel to it can be processed.

[0023] The prism and fixture assembly platform of this technical solution, through the platform body 1 and positioning plate 2, cooperates with the prism and fixture 3 to unify the height of the surface to be processed protruding from the fixture 3, ensuring the accuracy of subsequent processing. Moreover, the positions of the three surfaces to be processed can be fixed at one time, eliminating the need for multiple repeated loading of multiple fixtures 3, thus improving processing efficiency.

[0024] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
