一般来说,本发明涉及一种同心机加工装置,具体地说,本发明涉及一种用于对光通信环圈(ferrule),或者具有为200微米或其以下细内径(定位时使内圆周与外圆周同心)的圆筒形物体的外圆周表面进行机加工的装置和方法。 Generally, the present invention relates to a concentric machining apparatus and, more particularly, the present invention relates to the inner circumference of the ring for optical communication (ferrule), or with a small inner diameter of 200 microns or less (positioning concentric with the outer circumference) of the cylindrical outer circumferential surface of the object an apparatus and method for machining.

同心机加工是指对具有内圆周与外圆周的圆筒形物体进行机加工,以使外圆周与内圆周同心。 Machining refers to concentric cylindrical body having an inner circumference and an outer circumference of the machining, so that the outer circumference of the inner circumference concentric. 为了进行同心机加工,需将一针或细丝插入到细内孔中。 For concentric machining, a needle or filaments need to be inserted into the internal bore.

图1是常规的同心环圈机加工系统的示意图。 Figure 1 is a schematic conventional concentric ring machining system. 为了对环圈110进行同心机加工,将细丝120插入到多个环圈110的内孔中,细丝120的两端固定到固定装置100上,在细丝120上施加张力,然后利用抛光轮130对环圈110的外圆周表面进行机加工。 In order for the loop 110 is machined concentrically, the filament 120 is inserted into the hole 110 in a plurality of loops, both ends of the filament 120 is fixed to the fixing device 100, the tension applied to the filament 120, then using the polishing Wheel 130 pairs of the outer circumferential surface of the ring 110 is machined.

图2A和2B为用于说明图1所示同心机加工系统的机加工原理的示意图。 Figures 2A and 2B for explaining the principle of concentric machining machine shown in Figure 1 is a schematic diagram of the processing system.

为了对具有一定内径和外径的圆筒形物体210进行同心机加工,将一经过高精度加工的钢丝220插入到圆筒形物体210的内孔中,并以插入的钢丝220的中心取作为圆筒形物体210的内径中心,利用抛光轮230对圆筒形物体210的外圆周表面280的进行机加工去掉预定的数量290。 In order for a cylindrical object having a certain inner diameter and an outer diameter of 210 concentric machining precision after the machining of a wire 220 is inserted into the bore of the cylindrical body 210, and the insertion of the wire 220 is taken as the center the inner diameter of the cylindrical body 210 of the center, use the polishing wheel 230 pairs of the outer circumferential surface of the cylindrical body 210 of the 280 were machined to remove a predetermined number of 290. 因此,在对与内径中心240同心的圆筒形物体210的外圆周表面280的进行机加工之后,不同的内径和外径(中心)变得相同。 Accordingly, after the outer circumferential surface of the cylindrical body 240 concentrically with the center of the inner diameter 210 is machined 280 different inner and outer diameters (center) becomes the same.

然而,常规的机加工方法在机加工范围和精度方面存在某些问题。 However, the conventional method of machining certain problems in terms of range and precision machining.

(1)很难找到适合非常小内径的钢丝。 (1) It is difficult to find suitable for very small diameter wire. 而且在对机加工对象进行同心机加工时,由于内径太小,这样一种钢丝也无法承受施加在其两端的张力。 And when the object of machined concentric machining, the inner diameter is too small, it can not afford such a wire is applied at both ends of the tension.

(2)如果机加工对象的内圆周面是带锥度的或者是不规则形状的,就不可能进行同心机加工。 (2) If the inner circumferential surface of the machined object is tapered or irregular shape, it is impossible concentrically machined. 图3A表示插入到用于进行同心机加工的锥形内孔310中的钢丝320。 3A shows the tapered for insertion into the concentrically machined hole 310 in the wire 320. 如图中所示,尽管插入了钢丝320,由于内径是变化的,不可能进行同心机加工。 As shown, although the wire 320 is inserted, the inner diameter is changed, it can not be machined concentrically.

(3)提高精度受到限制。 (3) improve the accuracy is limited. 图3B是插入到机加工对象330的内孔的钢丝340的侧视横断面图。 3B is a side cross-sectional view of the inner bore of the object is inserted into the machine 330 of the wire 340. 这里,如果在该内孔和钢丝之间的插入裕度为0.3微米,钢丝340的机加工精度是0.2微米,则内孔的机加工精度是0.5微米。 Here, if the margin is inserted between the bore and the wire is 0.3 m, the machining accuracy of the wire 340 is 0.2 m, the machining accuracy of the inner holes is 0.5 micrometers. 因此,可以产生最大1微米的误差,机加工对象330不适于精密机加工。 Therefore, it can produce up to 1 micron in error, the object 330 is not suitable for machining precision machining.

(4)在机加工对象的内圆周表面和插入到机加工对象的内孔的钢丝之间的摩擦很可能刮伤该内圆周表面或使之变形。 (4) between the inner circumferential surface of the machined object and inserted into the hole of the machined object is likely to scratch the wire friction in the inner circumferential surface or deform.

(5)在通过插入一钢丝同时对多个环圈进行机加工时,可能由于在多个环圈之间进入外部物质而产生误差,因此,不能保证精密机加工。 (5) In the same time by inserting a plurality of wire loops machined, may be due to a plurality of loops between the substance into the external errors, and therefore, can not guarantee precision machining.

偏心度是指当机加工对象400在卡头410中旋转时,内径中心610偏离旋转中心620的程度。 Eccentricity means that when machining an object 400 is rotated in the chuck 410, the inner diameter of the center of the center of rotation 610 degree 620. 这里,令旋转中心620为座标原点。 Here, let the coordinates of the center of rotation 620 of origin. 于是,偏心度的水平和竖直分量分别为Δx和Δy。 Thus, the horizontal and vertical components of eccentricity respectively Δx and Δy.

当主轴425由于伺服电动机420根据从控制器440接收的旋转控制信号旋转而旋转时,内径中心610描出一个圆630,其圆心是旋转中心620。 When the spindle 425 due to the servo motor 420 based on the rotation control signal received from the controller 440 is rotated to rotate, the inner diameter of the center 610 delineate a circle 630, its center is the center of rotation 620. 圆轨迹630的直径是同心度640。 The diameter of the circular path 630 640 concentricity. 可以求出在同心度640以及水平和竖直偏心度分量Δx和Δy之间的相互关系: You can find the relationship between the 640 and the concentricity of the horizontal and vertical components of eccentricity Δx and Δy of:

在主轴425旋转的过程中,水平和竖直偏心度分量Δx和Δy的变化满足方程1。 During rotation of the spindle 425, the change in the horizontal and vertical components of eccentricity Δx and Δy satisfying equation. 当需要时,由控制器440计算其变化。 When you need to calculate the change by the controller 440.

可取的是,主轴425的旋转中心与摄影机430的摄影中心一致,因为,当它们一致时,这二中心成为座标原点,因此减少了为了得到同心度以及水平和竖直偏心度分量Δx和Δy所需的计算量。 Preferably, the rotation center axis 425 coincides with the camera imaging center 430, because, when they coincide, these two become the origin at the center, thus reducing the order to obtain concentricity and eccentricity of the horizontal and vertical components Δx and Δy amount of computation required.

在步骤515中,控制器440根据从摄影机430接收的图像数据计算水平和竖直偏心度分量Δx和Δy。 In step 515, the controller 440 to calculate the level of the image data received from the camera 430 and the vertical component of eccentricity Δx and Δy. 在步骤520中,控制器440将每一水平和竖直偏心度分量Δx和Δy与0相比较。 In step 520, the controller 440 each horizontal and vertical components Δx and Δy eccentricity compared with 0. 如果水平和竖直偏心度分量Δx和Δy都为0,控制器440在步骤535中产生一个机加工指令。 If the horizontal and vertical components of eccentricity Δx and Δy are 0, the controller 440 generates a machining instruction in step 535. 在步骤540中,控制器440令抛光用电动机480旋转,以便利用抛光工具485对机加工对象400进行机加工,如果完成机加工,利用自动进料装置由卡头410卸下机加工对象400。 In step 540, the controller 440 so that the rotating polishing motor 480 to take advantage of the polishing tool 485 pairs of machining the object 400 to be machined, if complete machining, the use of automatic feeding device 410 by the card first remove the machining objects 400.

如果偏心度不为0,在步骤525中,控制器440产生对于水平分量Δx的该水平方向机加工控制信号472x,以及对于竖直分量Δy的该竖直方向机加工控制信号472y。 If eccentricity is not 0, in step 525, the controller 440 generates a horizontal component Δx for the horizontal machining control signal 472x, and the vertical component Δy the vertical machining control signal 472y. 该水平方向机加工控制信号472x以及该竖直方向机加工控制信号472y分别通过旋转刷触点460提供到水平和竖直压电陶瓷470x和470y。 The horizontal machining control signal 472x and vertical machining control signal 472y are provided by rotary brush contacts 460 to the horizontal and vertical piezoelectric ceramic 470x and 470y.

如在图4A和4B中所示,当接收到水平方向机加工控制信号472x时,水平压电陶瓷470x伸展,于是沿竖直方向位移卡头410。 As shown in Fig. 4A 4B, when receiving the horizontal machining control signal 472x, 470x the level of piezoelectric ceramics stretch, so the vertical displacement along the chuck 410.

按照对卡头410定位的另一种方法,卡头410以及水平压电陶瓷470x和竖直压电陶瓷470y以整体方式联系,使得水平压电陶瓷470x和竖直压电陶瓷470y响应于水平方向机加工控制信号472x和竖直方向机加工控制信号472y,因此,卡头410沿水平方向和竖直方向位移。 Another method according to the positioning of the chuck 410, the chuck 410 and the horizontal and vertical piezoelectric ceramic piezoelectric ceramics 470x 470y contact in an integrated manner, so that the horizontal and vertical piezoelectric ceramic piezoelectric ceramics 470x 470y in response to the horizontal direction machining control signal 472x and vertical machining control signal 472y, therefore, the chuck 410 horizontally and vertically displaced. 这种方法不需要使用水平弹簧475x和竖直弹簧475y。 This method does not require the use of horizontal and vertical spring spring 475x 475y.

通过将压电陶瓷配置在水平弹簧475x和竖直弹簧475y的位置处,以及分别向各压电陶瓷提供与水平方向机加工控制信号472x和竖直方向机加工控制信号472y相对应的信号,可以构成控制卡头410的第三种优选的方法。 By the piezoelectric ceramic arranged at the horizontal position and vertical spring 475y spring 475x, and are each provided with a horizontal direction of the piezoelectric ceramic machining control signal 472x and vertical machining control signal corresponding to the signal 472y can Control the chuck 410 constitute a third preferred method. 压电陶瓷的数量增加,但机加工对象的位置可以更可靠地调节。 Increasing the number of piezoelectric ceramic, but the position of the object can be machined more reliably adjusted.

通过选择上述方法的其中之一,在步骤530中,校正偏心度,然后重复步骤500-530直到使偏心度为0。 By selecting one of the above-described method wherein, in the step 530, the eccentricity correction, then repeat steps 500-530 until the eccentric is 0.

如上所述,根据本发明,通过利用根据机加工对象的内径中心和旋转中心之间的距离相对应的电压值伸展的压电陶瓷,可以控制一其中安装有机加工对象的卡头。 As described above, according to the present invention, the inner diameter of the center by using the distance and the center of rotation between the machining object corresponding to a voltage value of the piezoelectric ceramic stretching, which can control an installation card first organic processed object. 因此,本发明具有如下的优点:(1)可以对机加工对象的外圆周表面进行机加工,与其内圆的尺寸和形状无关,因此,能够对具有带锥度的内圆或者不规则的内圆的机加工对象进行机加工,克服了的机加工范围局限性;(2)可以降低由于机加工工具引起的误差,与机加工的精度无关,因此,可以可靠地对要求高机加工精度(误差1微米或其以下)的零件进行机加工;(3)自动校正偏心度,因此,能够实现自动机加工并保证产品可靠性。 Accordingly, the present invention has the following advantages: (1) is machined on the outer circumferential surface of the object to be machined, regardless of their size and shape of the inner circle, it is possible to the inner circle within a circle with a tapered or irregular machining machining objects, overcoming the limitations of the machining range; (2) to reduce the error caused due to the machining tool, and the machining accuracy is independent, it is possible to reliably requires high machining accuracy (error 1 micron or less) of the machined parts; (3) automatic correction of eccentricity, it is possible to realize automatic machining and to guarantee the product reliability.

虽然是参照本发明的一个优选实施例表示和介绍本发明的,但本技术领域的技术人员会理解,在不脱离由所提出的权利要求限定的本发明的构思和范围的前提下,可以对其结构和细节进行各种改进。 While the reference to a preferred embodiment of the present invention shown and described the present invention, but skilled in the art will understand, without departing from the spirit and scope of the rights defined by the proposed requirements of the invention, can be its structure and details of various modifications.
