Method for machining lens cone part with mass center deviating from rotation center

Abstract

The invention relates to the field of machining, in particular to a method for machining a lens cone part with the mass center deviating from the rotation center. The method includes the following steps that a blank is cast; heat treatment is conducted, wherein quench aging is adopted; a bench worker scribes a blank allowance distribution line with the non-machining surface as a reference; all the surfaces of an installation seat are milled on a milling machine, and the 0.1 mm finish machining allowance is reserved in the ruler lower end face; holes are roughly turned on a lathe, and the 0.5 mm allowance is reserved for the single side of the finish machining surface; heat treatment is conducted, wherein distressing artificial aging is conducted through heat treatment, and machining stress is removed; the finish reference installation surface is machined, in other words, the planeness of the lower end face scraped by the bench worker is within 0.006 mm, the other surface is scraped, and the perpendicularity of the other surface and the lower end face is within 0.006 mm. The operation is simple, vibration generated in the machining process is low, dimensional tolerances of the part can be guaranteed, and part machining accuracy and production efficiency are improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing method for lens barrel parts whose center of mass deviates from the center of rotation. Background technique [0002] Lens barrel parts are often encountered in optoelectronic products. Due to strict installation position requirements, the structural center of mass of such parts is often not on the center of rotation. If it is processed on an ordinary lathe, not only the processing efficiency is low, but also the roundness and cylindricity of the hole are very poor, and the coaxiality of the holes at both ends is even more difficult to guarantee; due to the special structure, the wall thickness of this type of parts is thin, and the center of mass deviates from the rotation Center, when turning the inner hole, the roundness and cylindricity will be poor, and the position size of the hole center is also difficult to guarantee. The shape of this part is different ...

Problems solved by technology

The disadvantages of this type of method are that the longer the length of the part, the greater the overhang of the upper mandrel, the more the center of mass deviates from the axis of the hole, the greater the centrifugal force generated after the part rotates, and the greater the vibration generated during processing. It is difficult to guarantee geometrical tolerances such as degree and coaxiality, and the product qualification rate is low, which seriously affects the production cycle
