Description

一种任意曲率半径光学零件的加工设备A Processing Equipment for Optical Parts with Arbitrary Curvature Radius

技术领域 Technical field :

    本发明涉及光学精密制造技术领域,具体涉及一种任意曲率半径光学零件的加工设备。 The present invention relates to the technical field of optical precision manufacturing, in particular to a processing equipment for optical parts with arbitrary curvature radius.

背景技术:Background technique:

    目前,常规的不同曲率半径工件抛光制造技术,是利用和工件面型吻合的磨具或抛光盘进行抛光制造光学零件。这类方法中的抛光用具有一个相同的特征,有相对较硬和固定不变的面型,因此,在实际的加工中,对不同面形的光学零件,需要制作不同面形的专门的抛光磨具,同时,在加工的过程中需要不断检测和校正精磨抛光磨具的面形,才能保证加工的继续。这是一个需要不断重复的过程,稍有不慎就会制造出废品。在整个加工过程中,需要根据零件面形的变化,不断修正抛光模具,以满足被加工对象精度的需求。因而在上述传统方法中人为经验因素也是一个非常重要的条件,很难实现自动化,不能通过设备的精度控制工件的加工精度。 At present, the conventional polishing and manufacturing technology for workpieces with different curvature radii is to use abrasive tools or polishing discs that match the surface shape of the workpiece to polish and manufacture optical parts. The polishing in this type of method has the same feature, a relatively hard and fixed surface shape. Therefore, in actual processing, for optical parts with different surface shapes, it is necessary to make special polishing materials with different surface shapes. At the same time, in the process of processing, it is necessary to continuously detect and correct the surface shape of the fine grinding and polishing abrasive to ensure the continuation of processing. This is a process that needs to be repeated constantly, and a little carelessness will create waste products. During the entire processing process, it is necessary to continuously modify the polishing mold according to the change of the surface shape of the part to meet the precision requirements of the processed object. Therefore, the human experience factor is also a very important condition in the above-mentioned traditional methods, it is difficult to realize automation, and the machining accuracy of the workpiece cannot be controlled by the accuracy of the equipment.

    在公开的资料中,也有一些其它技术可以实现任意曲率半径工件表面的加工,中国专利ZL96198445.7是美国罗切斯特大学发明的一种用磁流变流体精加工工件表面的方法,该方法是将磁流变液置于一个转动的轮子表面,带动磁流变液到一个磁场中,工件和磁场有一定的间隙,磁流变液在通过这个间隙时被磁化,并形成瞬时精加工工具,用于与工件表面的部分接触并去除工件表面这部分的材料。它类似于一个接触面很小的点接触式研磨抛光,来实现需要的面形和光滑表面,需要结合超精密的机械系统和数控技术来实现。中国专利CN 1872494A介绍了一种磁流变柔性精磨抛光设备和方法,其要求工件主轴装置是移动、自转和摆动的三维运动主轴装置,主要是由摆动机构、上下滑动机构和变速旋转机构组成,机座向上通过连接轴连接有摆架,连接轴中心现即抛光加工控制的虚拟轴,通过控制连接轴跟工件的位置关系实现不同曲率半径光学零件的加工,这种方式对加工零件的曲率半径范围有一定的限制,该方法实现不同曲率半径加工过程中,零件所绕摆点位置是固定不动的,要实现不同零件的加工时,只能通过改变摆杆的长度来实现。 In the public information, there are also some other technologies that can realize the processing of the workpiece surface with any curvature radius. The rheological fluid is placed on the surface of a rotating wheel, which drives the magnetorheological fluid into a magnetic field. There is a certain gap between the workpiece and the magnetic field. The magnetorheological fluid is magnetized when passing through this gap, and forms an instantaneous finishing tool for Contact with and remove material from a portion of the workpiece surface. It is similar to a point-contact grinding and polishing with a small contact surface to achieve the required surface shape and smooth surface, which requires a combination of ultra-precision mechanical systems and numerical control technology. Chinese patent CN 1872494A introduces a magnetorheological flexible fine grinding and polishing equipment and method, which requires the workpiece spindle device to be a three-dimensional motion spindle device that moves, rotates and swings, and is mainly composed of a swing mechanism, an up and down sliding mechanism and a variable speed rotation mechanism , the machine base is connected upwards with a pendulum through the connecting shaft, and the center of the connecting shaft is now the virtual axis controlled by the polishing process. By controlling the positional relationship between the connecting shaft and the workpiece, the processing of optical parts with different curvature radii can be realized. This method affects the curvature of the processed parts The range of radius has a certain limit. During the processing of different curvature radii, the position of the pendulum point around which the part is fixed is fixed. To realize the processing of different parts, it can only be realized by changing the length of the pendulum.

    上述的加工方法都是可以实现球面光学零件的加工,但是在技术上还存在一定限制,传统的方法需要采用特殊的工装磨具,在进行单件光学零件生产时,其加工成本较高,中国专利ZL96198445.7采用的是点接触式的方法,其用于球面或者平面光学零件加工时,加工效率低,中国专利CN 1872494A介绍的方法能实现球面光学零件的加工,且具有较高的加工效率,但是其只能加工部分曲率半径范围的球面光学零件。 The above-mentioned processing methods can realize the processing of spherical optical parts, but there are still certain limitations in technology. The traditional method needs to use special tooling and abrasive tools. When producing single-piece optical parts, the processing cost is relatively high. China Patent ZL96198445.7 adopts a point-contact method, which has low processing efficiency when used for processing spherical or planar optical parts. The method introduced in Chinese patent CN 1872494A can realize the processing of spherical optical parts and has high processing efficiency , but it can only process spherical optical parts with a partial radius of curvature.

具体实施方式 Specific implementation methods :

下面结合附图对本发明做详细地说明。 The present invention will be described in detail below in conjunction with the accompanying drawings.

球面光学零件被加工表面是某个球体的一部分,其在空间上一个有一个旋转对称点,即球心。零件的加工采用摆动的运动方式时,要求球面光学零件绕球心的摆动,才能够保证球面光学零件的表面加工出来为球面,否则将会形成一个不规则面。 The processed surface of spherical optical parts is a part of a sphere, which has a rotational symmetry point in space, that is, the center of the sphere. When the part is processed in a swinging motion, the spherical optical part is required to swing around the center of the sphere to ensure that the surface of the spherical optical part is processed into a spherical surface, otherwise an irregular surface will be formed.

现有技术中,参见图1,在实现不同曲率半径半径加工时,保持摆点的位置不变,即加工光学零件6的球心O点的位置是保持不变的,通过调整主轴装置4的长度来实现。该方法要求摆轴装置2通过轴承固定在机座1上,主轴装置4固定安装在摆轴装置2上,且摆轴装置2与主轴装置4的交点为光学零件6的球心O点。 In the prior art, referring to Fig. 1, when realizing machining with different radii of curvature, the position of the pendulum point is kept constant, that is, the position of the spherical center O point of the processing optical part 6 is kept constant, and by adjusting the position of the spindle device 4 length to achieve. This method requires that the swing shaft device 2 is fixed on the machine base 1 through bearings, the spindle device 4 is fixedly installed on the swing shaft device 2, and the intersection point of the swing shaft device 2 and the spindle device 4 is the spherical center O point of the optical component 6 .

其核心的思想是:摆轴装置2可以绕自身旋转中心线转动,进而带动主轴装置4绕球心O点往复摆动。 Its core idea is: the pendulum shaft device 2 can rotate around its own rotation center line, and then drive the main shaft device 4 to swing back and forth around the center of the sphere at O.

该方法实现了光学零件6绕其球心O点的往复摆动,可用于球面光学零件的加工,但是由于主轴装置4的长度是有限的,在实际应用过程中不可能将主轴装置4的长度的变化范围从0mm变化到无穷长,所以该方法存在的问题是只能够实现部分曲率半径球面光学零件的加工。 This method realizes the reciprocating swing of the optical part 6 around its spherical center O point, and can be used for the processing of spherical optical parts, but because the length of the main shaft device 4 is limited, it is impossible to adjust the length of the main shaft device 4 in the actual application process. The range of variation varies from 0mm to infinity, so the problem with this method is that it can only realize the processing of spherical optical parts with partial curvature radius.

参见图2,本发明逆向思维,突破了传统思路的限制,给出了一种任意曲率半径球面光学零件的加工方法,摆轴装置2铰接安装在机座1上, 摆臂装置3铰接安装在摆轴装置2上,主轴装置4铰接安装在摆臂装置3上。 Referring to Fig. 2, the reverse thinking of the present invention breaks through the limitation of traditional ideas, and provides a processing method for spherical optical parts with arbitrary curvature radius. On the swing shaft device 2 , the main shaft device 4 is hingedly mounted on the swing arm device 3 .

其设计思路是:在实现不同曲率半径半径加工时,保持主轴装置4的长度不变,加工光学零件6的球心O点在空间中位置可变,且该方法能够保证,在加工过程中,光学零件6绕球心O点往复摆动。球面光学零件绕球心的摆动,需要保证的是主轴装置4或者其延长线与摆轴装置2或者其延长线必须相交于一点,且该相交点就是球心位置。主轴装置4绕摆轴装置2作往复摆动,即实现的动作实际是主轴装置4绕球心O点的往复摆动。 Its design idea is: when realizing machining with different radii of curvature, keep the length of the spindle device 4 constant, and the position of the spherical center O of the optical part 6 in the process can be changed in space, and this method can ensure that during the machining process, The optical part 6 swings back and forth around the point O of the center of the sphere. When the spherical optical part swings around the center of the sphere, it needs to be ensured that the main shaft device 4 or its extension line and the pendulum shaft device 2 or its extension line must intersect at one point, and the intersection point is the position of the center of the sphere. The main shaft device 4 swings back and forth around the pendulum shaft device 2, that is, the action realized is actually the reciprocating swing of the main shaft device 4 around the center of the sphere O.

本发明给出的一种任意曲率半径光学零件的加工方法,是通过改变主轴装置4与摆轴装置2在空间的相交点的位置,实现不同曲率半径的球面光学零件的加工。 The present invention provides a method for processing optical parts with arbitrary curvature radii, which realizes the processing of spherical optical parts with different radii of curvature by changing the position of the intersection point of the spindle device 4 and the swing shaft device 2 in space.

在该方法的指导下,要改变主轴装置4与摆轴装置2在空间的相交点位置的方式有很多种,其中: Under the guidance of this method, there are many ways to change the position of the intersection point of the main shaft device 4 and the pendulum shaft device 2 in space, among which:

方法一是保持主轴装置4固定不动,通过调整摆轴装置2的角度,即引起摆轴装置2与主轴装置4的夹角变化来实现。 The first method is to keep the main shaft device 4 fixed, which is realized by adjusting the angle of the swing shaft device 2 , that is, causing the angle between the swing shaft device 2 and the main shaft device 4 to change.

方法二是保持主轴装置4和摆轴装置2的夹角不变,通过调整主轴装置与摆轴装置2之间的距离来实现。 The second method is to keep the included angle between the main shaft device 4 and the pendulum shaft device 2 unchanged, and realize it by adjusting the distance between the main shaft device and the pendulum shaft device 2 .

方法三是保持摆轴装置2固定不动,通过调整主轴装置4的角度,即引起摆轴装置2与主轴装置4的夹角变化来实现。 The third method is to keep the pendulum shaft device 2 fixed and realize by adjusting the angle of the main shaft device 4 , that is, causing the included angle between the pendulum shaft device 2 and the main shaft device 4 to change.

方法四是保持主轴装置4的角度不变,通过调整摆轴装置2的角度和调整主轴装置与摆轴装置2之间的距离来实现。 The fourth method is to keep the angle of the main shaft device 4 unchanged, which is realized by adjusting the angle of the swing shaft device 2 and adjusting the distance between the main shaft device and the swing shaft device 2 .

方法五是保持摆轴装置2的角度不变,通过调整主轴装置4的角度和调整主轴装置与摆轴装置2之间的距离来实现。 The fifth method is to keep the angle of the pendulum device 2 constant, and realize it by adjusting the angle of the main shaft device 4 and adjusting the distance between the main shaft device and the pendulum device 2 .

方法六是保持主轴装置与摆轴装置2之间的距离不变,通过调整主轴装置4的角度和调整与摆轴装置2之间的角度来实现。 The sixth method is to keep the distance between the main shaft device and the swing shaft device 2 constant, and realize by adjusting the angle of the main shaft device 4 and the angle between the main shaft device 4 and the swing shaft device 2 .

方法七是调整主轴装置与摆轴装置2之间的距离,同时调整主轴装置4的角度和调整与摆轴装置2之间的角度来实现,该方式为优选方案,由于其对磨头的调整机构要求较为简单,且易于实现,本发明给出了这种优选方案的具体实现方式。参照图3所述,本发明提供的一种任意曲率半径光学零件的加工设备,包括机座1、摆轴装置2、摆臂装置3、主轴装置4和磨头装置5,摆轴装置2铰接安装在机座1上,连接点为坐标原点,摆轴装置2设置于XOZ平面上且与Z轴的夹角可调,摆轴装置2的另一端与摆臂装置3铰接,摆臂装置3设置于XOY平面上且在XOY平面上可以绕着摆轴装置2做往复的摆动,主轴装置4固定在摆臂装置3上,且主轴装置4在XOZ平面内与Z轴的夹角可调,主轴装置4可沿摆臂装置3在X轴方向上进行左右平行移动,所述磨头装置5固定在机座1上,磨头装置5设置于XOZ平面内且与Z轴平行设置,磨头装置5可沿Z轴方向进行上下平行移动,磨头装置5也可沿着X轴方向进行左右平行移动。 The seventh method is to adjust the distance between the main shaft device and the swing shaft device 2, and at the same time adjust the angle of the main shaft device 4 and the angle between the swing shaft device 2 and adjust it. The institutional requirements are relatively simple and easy to implement, and the present invention provides a specific implementation of this preferred solution. Referring to Fig. 3, the present invention provides a processing equipment for optical parts with any radius of curvature, comprising a machine base 1, a swing shaft device 2, a swing arm device 3, a spindle device 4 and a grinding head device 5, and the swing shaft device 2 is hinged Installed on the base 1, the connection point is the coordinate origin, the swing shaft device 2 is set on the XOZ plane and the angle with the Z axis is adjustable, the other end of the swing shaft device 2 is hinged with the swing arm device 3, and the swing arm device 3 It is arranged on the XOY plane and can swing back and forth around the swing shaft device 2 on the XOY plane.
