Embodiment 1

[0053] To provide a special-shaped lens production process for the present invention, this production process needs to use three kinds of fixtures:

[0054] First Fixture 1: Binding image 3 , which includes a first bottom plate 11, a first side plate 12, and a second side plate 13, and the first side plate 12 and the second side plate 13 are vertically fixed at both ends of the top surface of the first bottom plate 11 with bolts respectively; The plate 12 is fixedly provided with a first cylinder 121 towards the side of the second side plate 13, and the output end of the first cylinder 121 is towards the second side plate 13; A square-shaped abutment block 131 is fixed, and the side of the second side plate 13 away from the first side plate 12 is fixed with a fixed plate 4a for clamping on the machining center; the first bottom plate 11 is also provided with rounded corners Rectangular feed hole 111;

[0055] Second Fixture 2: Bonding Figure 4 , which includes a second bott...

Embodiment 2

[0073] combine figure 2 , the present embodiment provides a special-shaped lens made by the production process in Embodiment 1, including a light-reflecting end 81, and the two ends of the light-reflecting end 81 are respectively integrally provided with a light-incoming end 53 and a light-outgoing end 54, and the light-incoming end 53 The central axis of the light-emitting end 54 is perpendicular to each other; the side of the light-reflecting end 81 away from the light-incoming end 53 and the light-emitting end 54 is provided with a slope 61, and the normal line of the slope 61 is on the same plane as the central axis of the light-incoming end 53 and the light-emitting end 54 , and the angle between the normal of the slope 61 and the central axis of the light-incoming end 53 is 45°;

[0074] And the intersection point of the central axis of the light entrance 53 and the central axis of the light exit 54 is located on the inclined plane 61; the light entrance 53 and the ligh...

Abstract

The invention provides a special-shaped lens production process, which relates to the technical field of precision machining. The special-shaped lens production process includes: S10: Take a cross-shaped blank, and clamp the two sides of the cross-shaped blank with first clamps and fix it on the machining center , and make one end of the cross-shaped block align with the tool of the machining center; S20: process one end of the cross-shaped block into a cylindrical shape, rotate the first fixture three times at the same time with 90° rotation, and align the cross-shaped block with the three The end is also processed into a cylindrical shape; S30: Cut two cylinders without round holes along the middle part of the cross-shaped block, and the angle between the normal line of the inclined plane formed after cutting the cross-shaped block and the central axis of the round hole is 45°; S40: Hole processing and surface processing of semi-finished products to form special-shaped lenses. The present invention can make the central axis of the light-incoming end and the central axis of the light-emitting end meet the precise vertical relationship at the same time, and be on the same plane, which solves the production problem.

Description

technical field [0001] The invention relates to the technical field of precision manufacturing, in particular to a special-shaped lens production process. Background technique [0002] A microscope is a high-precision instrument used to observe microscopic structures and is widely used in various fields such as medical treatment, biology, metal, and surface treatment. [0003] Microscopes usually include structures such as eyepieces, objective lenses, mounting platforms, and mirrors. The eyepieces and objective lenses of existing microscopes are arranged perpendicular to each other, so a special-shaped lens is also used in the microscope to change the angle of light. [0004] A special-shaped lens is usually an L-shaped structure composed of a light exit end, a light reflection end, and a light entry end. The central axis of the end and the central axis of the light-incoming end must be on the same plane. The existing production process is difficult to ensure that the ligh...
