Splicing device for numerical control machining for square optical element

Abstract

The invention discloses a splicing device for numerical control machining for a square optical element. The splicing device for numerical control machining for the square optical element comprises a square supporting plate which is of a boss structure and comprises an upper boss and a lower boss, wherein the area of the cross section of the lower boss in the horizontal direction is larger than that of the upper boss, and the area of the upper boss is the same as that of the optical element to be machined; a silica gel pad and waterproof cloth are further sequentially arranged on the upper boss; and during use, the optical element to be machined is arranged on the waterproof cloth. The splicing device for numerical control machining for the square optical element further comprises four splicing blocks which are arranged above the lower boss and used for clamping the optical element to be machined and arranged on the upper boss after being connected with one another, and the upper surface of the optical element to be machined is slightly higher than the upper surface of each splicing block; and a plurality of magnetic strips used for fixing the waterproof cloth are further arranged at the outer side of the top surface of each splicing block. The splicing device has the two functions of element clamping and polishing solution storage at the same time, realizes immersed polishing for the element, and improves the polishing stability for the element.

Description

technical field [0001] The invention relates to the technical field of optical processing, in particular to a splicing device for numerically controlled processing of square optical elements. Background technique [0002] With the development of high-power laser devices, telescope systems, aerospace and ultraviolet lithography and other fields, the demand for square optical components is increasing, and the requirements for component processing accuracy and processing efficiency are also increasing. The CNC polishing technology of small tools precisely controls the rotational speed of the polishing tool, the processing path and the residence time of the polishing tool at each processing point on the surface of the component through the computer. Compared with the full-aperture polishing technology such as ring polishing, the determinism of the surface material of the optical component can be achieved. Processing is the mainstream technology for high-precision processing of o...

Problems solved by technology

[0003] CNC polishing usually uses cerium oxide polishing fluid to achieve high-precision and ultra-smooth surface processing of optical components, but due to its non-immersion contact polishing characteristics, a large amount of heat generated by the friction between the polishing tool and the surface of the optical component during processing It will cause the local temperature to rise, aggravate the aging speed of the polishing tool, and affect the stability of the polishing process

In addition, under the joint action of the polishing tool rotation and feed movement, the polishing liquid is seriously lost in the corner area of ​​the component, making the concentration of the polishing liquid on the surface of the component unevenly distributed, which further reduces the stability of the polishing process and affects the optical components. Final machining accuracy and machining efficiency
