Abstract

The invention provides a camera lens machining method, and relates to the technical field of camera lens machining. The method aims to solve the problems that the appearance error is large and the hole opening yield is low when a camera lens is machined. The camera lens machining method comprises the following steps that a material is machined by using a copying machine, so that the shape of the material is the same as that of a finished product, and the end face size of the machined material uniformly expands with respect to the size of the end face of the finished lens; the material machinedthrough the copying machine is fixed to a first numerical control machine tool through a first positioning assembly, then the first numerical control machine tool is used for machining the material,so that the end face size of the material and the end face size of the finished lens are the same; and the material machined through the first numerical control machine tool is fixed to a second numerical control machine tool through a second positioning assembly, and the second numerical control machine tool is used for punching the material at set positions. According to the camera lens machining method, the machined camera lens is small in appearance size error and high in hole opening yield.

Description

technical field [0001] The invention relates to the technical field of camera lens processing, in particular to a camera lens processing method. Background technique [0002] At present, when processing camera lenses, the outer contour of the material is first processed by a manual profiling machine, so that the cross-sectional shape and size of the material are the same as the shape and size of the finished product, and then holes are opened on the finished material by using a CNC machine tool . [0003] However, when the above-mentioned processing method is used to process the racetrack camera lens, and the length and width deviation ratio of the finished racetrack camera lens is relatively large (for example, the length and width deviation ratio reaches more than three times), but the cross-sectional area is small, use a manual profiling machine The shape of the processed material cannot reach the required error range, that is to say, using a manual profiling machine to ...
