Problems solved by technology

CNC machining is a flexible processing technology, which is suitable for the processing of aspheric parts of various shapes and sizes, but the high-precision surface shape must be obtained through repeated testing and repeated grinding, and the processing equipment is expensive and the operation technology is complicated. is an expert technique
Although it is easier to process high-precision aspheric parts than the traditional manual grinding and polishing method, the processing cycle is still long and the processing cost is high, so it is not suitable for mass production
As far as the current situation is concerned, there is no aspheric processing technology comparable to the processing technology of spherical parts, and it is suitable for both single-piece and batch efficient processing technology

Embodiment Construction

[0018] Such as figure 1 Shown is a schematic diagram of the trajectory intercepted in a cone. On a cone with a half-vertex angle α, from the vertex A to a certain point D along the generatrix of the cone whose distance is L, if a plane a-a is used to truncate the cone, the angle between the plane and the axis of the cone is φ 1 =90°, the trajectory of the curve equation of a circle can be cut; if the angle between the plane b-b and the axis of the cone is 90°>φ 2 > within the range of α, the trajectory of an ellipse curve equation can be cut; if the angle between the plane c-c and the axis of the cone is φ 3 = α, the trajectory of a parabolic curve equation can be cut; if the angle between the plane d-d and the axis of the cone is α>φ 4 >-α range, can cut a hyperbolic curve equation track. In a word, any given quadratic curve equation trajectory can be intercepted on the cone only by obtaining the parameters α, φ and L related to the given quadratic curve equation. How to ...

Abstract

The present invention relates to a method for processing optical aspherical part and its equipment. Said method includes the folloiwng steps: on the cone body, utilizing mathematical calculation to define the section which possesses the trace identical to that of required curve, i,e, defining position parameter of said section; mounting the cone body on a device with trace intercepting body; matching the trace intercepting body end with abrasive wheel, coupling the cone body with part, making part rotate and oscillate together with the cone body around the oscillating axle, fixedly connecting the trace intercepting body and abrasive wheel so as to be able to accurately transfer the curve trace intercepted from the cone body onto the part in the processing process. Said invention can be used for processing concave-convex secondary aspherical and high-order aspherical part, and possesses the advantages of good universality, high accuracy, high efficiency and low cost.

Description

technical field [0001] The invention relates to a processing method and device for optical parts. Background technique [0002] The use of aspherical parts in the optical system has incomparable advantages over spherical parts, but due to the difficulties in processing and testing aspheric parts, it has not been widely used for a long time. However, people have been working hard to explore aspheric surface processing and detection technology, which has promoted the rapid development and application of aspheric surface processing technology. [0003] There are dozens of various aspheric surface processing methods that people have studied so far. According to their processing principles, they can be roughly divided into four categories: removal processing, additional processing, deformation processing and metamorphic processing methods. Although there are many processing methods, in addition to traditional manual processing and numerical control processing methods, most of th...
