Abstract
The utility model provides a plane milling optical prism clamp, which comprises a product support frame, two switch type magnetic bases, three fixed product pressing blocks, three springs and three rubber damping sheets; the product support frame is of a hollow double-layer stepped ring structure, two switch type magnetic bases are mounted on a lower-layer step, a clamp can be fixed on the table top of the plane milling and grinding machine through the switch type magnetic bases, the surface of an upper-layer step is parallel to the bottom surface of the product support frame, and 3 pressing block holes and 3 rubber damping sheet holes are formed in the upper-layer step; the product fixing pressing block is connected to the product supporting frame through a spring, so that the optical rubber plate of the optical prism is clamped on the upper-layer stepped surface of the product supporting frame, and the friction force is increased through the rubber damping sheet to prevent the optical rubber plate of the optical prism from moving left and right; the utility model provides an anchor clamps have easy operation, the plane mills the characteristics that optical prism angle precision is high after grinding.
Description
Technical Field
The utility model belongs to optics cold processing equipment field specifically indicates a plane mills and grinds optical prism anchor clamps.
Background
A prism is a polyhedral optical element made of a transparent material (e.g., glass, crystal, etc.). The most common prism has a 45-degree right-angle prism, three surfaces of the prism are polishing surfaces, two side surfaces of the prism are frosted surfaces, and high angle precision between the polishing surfaces is required to be ensured in order to ensure that a light path when light passes through the prism does not deviate.
Because the conventional 45-degree right-angle prism has a 45-degree right-angle triangle cross section, in order to polish and process the right-angle surface of the prism with high precision, the prism product is required to be polished on an accurate 45-degree right-angle glass polishing glue block, then the polishing glue block is polished on a glass polishing glue plate, and an aluminum buckle plate is bonded at the back of the glass polishing glue plate and is used for facilitating the operation of polishing the upper surface of the prism product; in order to make polishing faster, a prism product needs to be subjected to high-precision plane milling before polishing, but the back of the prism product is provided with an aluminum buckle plate, so that the clamping of a plane milling optical prism is challenged, and a clamp convenient for product clamping is needed to realize the high-precision plane milling of the prism.
Disclosure of Invention
The utility model aims to solve the technical problem that need provide a plane milling optical prism anchor clamps for optical prism mills clamping dismouting easy operation around the mill at the plane, and guarantees to mill the enough height of prism precision of mill-out.
The utility model discloses a plane milling optical prism anchor clamps, including product support frame, on-off magnetic base, fixed product briquetting, spring and rubber damping fin, its characterized in that, the product support frame is the double-deck ladder ring structure of middle hollow, and on-off magnetic base is installed to lower floor's ladder, and the upper ladder surface is parallel with the bottom surface of product support frame, has the counter bore that is used for installing fixed product briquetting and the counter bore of rubber damping fin on the upper ladder, fixed product briquetting is an "L" shape buckle, through spring coupling on the product support frame, the rubber damping fin be the elastic block that bonds on the product support frame.
Drawings
The invention will be further described with reference to the accompanying drawings and examples;
FIG. 1 is a schematic cross-sectional view of a flat milling optical prism fixture;
fig. 2 is a schematic top view of a flat milled optical prism holder.
Detailed Description
Referring to fig. 1 and 2, the optical cement of the 45-degree right-angle prism product (11) is fixed on a 45-degree right-angle glass optical cement block (12), the optical cement of the optical cement block (12) is fixed on a glass optical cement plate (13), the glass optical cement plate (13) is a glass plate with parallel upper and lower surfaces, an aluminum buckle plate (14) is bonded on the back of the glass optical cement plate (13) and used for facilitating the operation of polishing the upper surface of the prism product (11), and in order to ensure the subsequent polishing precision, the upper surface of the prism product (11) after plane milling and grinding needs to be ensured to be parallel to the upper surface of the optical cement plate (13).
The utility model provides a plane milling optical prism clamp, which comprises a product support frame (2), two switch type magnetic bases (1), three fixed product pressing blocks (4), three springs (3) and three rubber damping sheets (5); the product support frame (2) is of a hollow double-layer stepped ring structure, two switch type magnetic bases (1) are mounted on the lower-layer steps, the whole clamp can be fixed on the table top of a plane milling and grinding machine through the switch type magnetic bases (1), the surface of the upper-layer steps is parallel to the bottom surface of the product support frame, and 3 counter bores for fixing product pressing blocks (4) and 3 counter bores for rubber damping sheets (5) are formed in the upper-layer steps; the product fixing pressing block (4) is connected to the product supporting frame (2) through the spring (3), so that the product fixing pressing block (4) can move up and down along the hole in the product supporting frame (2), the optical rubber plate (13) of the optical prism is clamped on the upper-layer stepped surface of the product supporting frame (2), and the friction force is increased through the rubber damping sheet (5) to prevent the optical rubber plate (13) of the optical prism from moving left and right; because the upper surface of the prism product (11) after the plane milling and grinding is parallel to the table surface of the plane milling and grinding machine, the upper surface of the optical rubber plate (13) can be ensured to be parallel to the table surface of the plane milling and grinding machine by the plane milling and grinding optical prism clamp; therefore, the upper surface of the prism product (11) after plane milling and grinding can be ensured to be parallel to the upper surface of the smooth rubber plate (13) finally.
