Description
종래 정밀연마, 특히 공작물을 연마함에 있어서, 공작물은 주축대와 심압대의 배치센터사이에 놓인다. 이러한 취부방식은 특히 벽이 매우 얇은 공작물의 경우에 취부중심의 영역에서 취부하기가 어려운 점이 있었다. 통상 이러한 공작물은 기하학적으로 정밀하게 예비연마할 수 없거나 예비연마후 가하여지는 열처리에 의한 왜곡에 관련된 동심성 오차와 같은 형상의 부정확성을 갖는다. 통상적으로 얇은 벽을 갖는 공작물의 이들 왜곡관련 진원성 오차의 제거는 공작물의 외경을 연마하는 것으로 보정될 수 없다. 즉, 중심의 진원성 오차는 외부의 원통형 연마중 치수 또는 동심성 오차로서 전달된다.In conventional micropolishing, in particular in grinding a workpiece, the workpiece lies between the placement center of the headstock and the tailstock. This type of mounting was difficult to mount in the area of the center of installation, especially for workpieces with very thin walls. These workpieces usually have inaccuracies in the shape, such as concentricity errors related to distortion due to heat treatment that cannot be geometrically precisely preliminary or applied after prepolishing. The elimination of these distortion related roundness errors of thin walled workpieces typically cannot be corrected by grinding the outer diameter of the workpiece. That is, the central roundness error is transmitted as a dimension or concentricity error during external cylindrical polishing.
본 발명은 중심에 형상오차를 갖는 공작물의 연마방법과 장치에 관한 것이다.The present invention relates to a method and apparatus for polishing a workpiece having a shape error at its center.

따라서, 본 발명의 목적은 공작물의 중심영역의 동심성 오차와 같은 형상의 부정확성이 연마중 완성품에 전달되지 않는 방법과 장치를 제공하는데 있다. 이와 같이 함으로서, 공작물의 최종연마전에 복잡한 중심연마작업이 필요없게 된다. 더욱이, 무결함의 외주면을 갖는 고품질의 공작물을 생산할 수 있다. 공작물의 1 회 취부로 완전한 외부윤곽이 완전하게 연마될 수 있다.It is therefore an object of the present invention to provide a method and apparatus in which inaccuracies in the shape, such as concentricity errors in the central region of the workpiece, are not transmitted to the finished product during polishing. This eliminates the need for complex central polishing before the final polishing of the workpiece. Moreover, it is possible to produce a high quality workpiece having a flawless outer circumferential surface. With a single installation of the workpiece, the complete outer contour can be completely polished.
이러한 목적은 방법에 관련된 청구범위의 제 1 항과 방법을 수행하기 위한 장치에 관련된 청구범위 제 2 항의 특징부분에 의하여 달성된다. 청구범위 제 3 항의 특징부분은 구조에 관하여 청구범위 제 2 항에 청구된 장치를 보다 구체화한다.This object is achieved by the features of claim 1 relating to the method and of claim 2 relating to an apparatus for carrying out the method. The characterizing part of claim 3 further embodies the device claimed in claim 2 with respect to the structure.
이러한 목적은 심압대 슬리이브에 착설된 심압대의 배치센터가 스프링요소가 구비된 압력핀으로 구성되는 것으로 달성될 수 있다. 이와 같이 연마될 공작물은 주축대의 작업스핀들의 대향된 배치센터에 대하여 축방향으로 가압된다. 이와 같은 경우에 있어서, 공작물은 안정대에 의하여 지지되어 위치가 고정될 수 있다. 본 발명의 실시형태에 있어서, 압력핀이 피스턴부분과 롯드부분으로 구성되고, 압력핀이 심압대 배치센터의 기초동체 내부에 착설된다. 심압대 배치센터를갖는 심입대 슬리이브는 중간위치로 후퇴될 수 있다. 따라서, 연마를 위한 공작물은 주축대측 중심영역과 안정대의 조오에 정확히 중심이 맞추어져 놓이게 된다.This object can be achieved by the arrangement center of the tailstock mounted on the tailstock sleeve consisting of a pressure pin with a spring element. The workpiece to be polished in this way is pressed axially against the opposed placement center of the work spindles of the spindle head. In such a case, the workpiece can be supported by the stabilizer and fixed in position. In the embodiment of the present invention, the pressure pin is composed of a piston portion and a rod portion, and the pressure pin is mounted inside the base body of the tail stock placement center. Cardiac sleeves with tailstock placement centers may be retracted to an intermediate position. Therefore, the workpiece for polishing is exactly centered on the jaw axis side of the spindle axis and the jaws of the stabilizer.
본 발명을 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.Referring to the present invention in more detail based on the accompanying drawings as follows.
연마기상에 공작물(5)을 취부하는 것이 예를 들어 도 1 에 도시되어 있다. 이 공작물(5)은 주축대(1)의 작업스핀들(30)의 배치센터(4)와심압대(3)의 센터(11)의 배치센터(6)사이에 취부된다. 작업스핀들(30)의 배치센터(4)와 슬리이브(13)의 배치센터(6)사이에 공작물을 취부하고 분리하는 것은 심압대의 이동으로 후진위치로 후퇴되는 심압대 슬리이브(13)에 의하여 이루어진다.The mounting of the workpiece 5 on the grinding machine is shown for example in FIG. 1. This work piece 5 is mounted between the placement center 4 of the work spindle 30 of the headstock 1 and the placement center 6 of the center 11 of the tailstock 3. Mounting and separating the workpiece between the placement center 4 of the work spindle 30 and the placement center 6 of the sleeve 13 is performed by the tailstock sleeve 13 being retracted to the retracted position by the movement of the tailstock. Is done.
주축대(1)와 심압대(3)는 Z-방향으로 이동할 수 있는 연마테이블(2)(일부만을 보임)상에 착설된다. 주축대(1)는 모터구동장치(도시하지 않았음)를 통하여 구동되는 작업스핀들(30)을 갖는다. 심압대(3)에는 심압대(3)의 하우징내부에서 축방향으로 이동가능한 심압대 슬리이브(13)가 구비되어 있다. 주축대(1)의 작업스핀들(30)과 심압대(3)의 슬리이브(13)의 중심축선은 상대측에 대하여 정확히 정렬되어 있다. 마찬가지로 정렬되는 종축선을 갖는 공작물(5)은 이들 사이에 취부된다. 가동형 조오(9)를 갖는 안정대(7)가 연마테이블(2)에 배열된다. 연마휠(16)을 갖는 연마스핀들(15)은 공작물 취부상태에 대하여 수직인 X-축의 방향으로 선반의 주축대(1)와 심압대(3)에 대하여 축방향으로 평행하게 놓일 수 있도록 배치된다. 아울러, 연마스핀들(15)은 선반의 Z-축에 대하여 축방향으로 평행하게 배치된다. 연마휠(16)은 공작물에 대하여 직각인 X-축의 방향으로 고정된다.The headstock 1 and the tailstock 3 are mounted on a polishing table 2 (shown only part) which is movable in the Z-direction. The headstock 1 has work spindles 30 driven through a motor drive device (not shown). The tailstock 3 is provided with a tailstock sleeve 13 which is axially movable within the housing of the tailstock 3. The central axis of the work spindles 30 of the main shaft 1 and the sleeve 13 of the tailstock 3 are exactly aligned with respect to the other side. Workpieces 5 having likewise aligned longitudinal axes are mounted between them. A stabilizer 7 with a movable jaw 9 is arranged on the polishing table 2. The polishing spindles 15 with the polishing wheels 16 are arranged to be axially parallel to the spindle headstock 1 and tailstock 3 of the lathe in the direction of the X-axis perpendicular to the workpiece mounting state. . In addition, the polishing spindles 15 are arranged axially parallel to the Z-axis of the shelf. The polishing wheel 16 is fixed in the direction of the X-axis perpendicular to the workpiece.
도 2 에서, 공작물은 주축대(1)의 배치센터(4)와 심압대(3)의 배치센터(6)사이에 취부되어 있다. 심압대(3)의 배치센터(6)에 지지되어 있는 센터(11)에서의 공작물(5)이 매우 얇은 벽을 가지므로 공작물의 취부중에 가하여지는 압축력에 의하여 공작물(5)의 벽이 얇은 부분에서 중심배치변형이 일어난다. 즉, 공작물(5)의 취부센터의 심압대측 영역이 심압대(3)의 절두원추형 배치센터(6)와 조합되어 심압대(3)의 배치센터(6)로부터 가하여지는 압축력에 의하여 원형의 형상으로 가압된다.In FIG. 2, the workpiece is mounted between the placement center 4 of the headstock 1 and the placement center 6 of the tailstock 3. Since the work piece 5 at the center 11 supported by the placement center 6 of the tail stock 3 has a very thin wall, the wall of the work piece 5 is thinned by the compressive force applied during the mounting of the work piece. Central displacement occurs at. That is, the tailstock side area of the mounting center of the workpiece 5 is combined with the truncated cone-shaped placement center 6 of the tailstock 3 and is circular in shape by the compression force applied from the placement center 6 of the tailstock 3. Is pressurized.
공작물(5)의 중심영역에서, 가동형 조오(9)를 갖는 안정대(7)가 접하게 되는 안정대 시이트(8)가 연마휠(16)에 의하여 연마되며, 이 연마휠은 X-축선을 따라서 공작물에 대하여 직각으로 배치되고 Z-축선에 대하여 축방향으로 평행하게 이동될 수 있게 되어 있으며 연마스핀들(15)상에 착설되어 있다. 공작물(5)은 이와 같이 기하학적으로 정확한 공작물(5), 즉, 진원성 오차가 없는 공작물(5)을 얻기 위하여 리셋트되고 마무리가공된다.In the center region of the workpiece 5, the stabilizer sheet 8, which is brought into contact with the stabilizer 7 with the movable jaw 9, is polished by the polishing wheel 16, which polishes the X-axis. It is thus arranged at right angles to the workpiece and able to be moved axially parallel to the Z-axis and mounted on the abrasive spindles 15. The workpiece 5 is reset and finished to obtain such a geometrically accurate workpiece 5, i.e., a workpiece 5 free of roundness errors.
도 3 은 심압대(3)의 슬리이브(13)의 배치센터(6)가 이루는 절두원추형의 구성에 대한 실시형태를 보인 것으로, 배치센터(6)가 마모에 의하여 탄화물(6A)이 달라붙어 있으며 슬리이브(13)의 종축선에 정렬된 안내요소 (24)에 배치되어 있다. 안내요소(24)는 직경이 단계적으로 변화하는중심종공을 가지며 이 중심종공은 배치센터의 단부측을 향하여 점점 작아진다. 안내요소(24)의 대향측 단부에서, 이 중심종공은 조절스크류(23)를 수용하기 위하여 최대직경을 갖는다. 점차로 중심종공의 직경은 작아져 소경부를 갖는다. 이 소경부에는 소경부의 직경에 맞는 직경을 가지고 일측단이 조절스크류(23)의 단부면에 접하고 타측단이 동일 직경을 갖는 압력핀(21)의 원통형 피스턴부분(26)의 단부면에 접하는 스프링요소(22)가 배열되어 있다. 원통형 피스턴부분(26)의 타측단부는 직경이 작은 축방향 롯드부분(27)을 갖는다. 이 롯드부분(27)은 안내요소(24)의 외부로 연장된 통공을 관통한다. 스프링요소(22)로 탄지된 압력핀(21)이 공작물(5)에 축방향의 힘(32)을 가한다.Figure 3 shows an embodiment of the configuration of the truncated cone formed by the placement center 6 of the sleeve 13 of the tailstock 3, the carbide 6A is stuck to the placement center 6 due to wear And arranged on a guide element 24 aligned with the longitudinal axis of the sleeve 13. The guide element 24 has a central bore that changes in diameter step by step, and the central bore becomes smaller toward the end side of the placement center. At the opposite end of the guiding element 24, this central longitudinal hole has a maximum diameter to accommodate the adjusting screw 23. Gradually, the diameter of the central longitudinal hole becomes small to have a small diameter portion. The small diameter portion has a diameter corresponding to the diameter of the small diameter portion, one end of which is in contact with the end face of the adjusting screw 23, and the other end is in contact with the end face of the cylindrical piston portion 26 of the pressure pin 21 having the same diameter. The spring elements 22 are arranged. The other end of the cylindrical piston portion 26 has an axial rod portion 27 having a small diameter. This rod portion 27 passes through a hole extending out of the guide element 24. The pressure pin 21, which is supported by the spring element 22, exerts an axial force 32 on the workpiece 5.
도 4 에서, 심압대(3)의 슬리이브(13)는 화살표를 따라서 중간위치 (10)로 후퇴되어 심압대(3)의 배치센터(6)가 공작물(5)에 더 이상 압력접촉하지 않는다. 그러나, 압력핀의 롯드부분(27)은 스프링요소(22)의 스프링 힘에 의하여 공작물(5)을 주축대(1)의 작업스핀들의 배치센터(4)에 가압한다.In FIG. 4, the sleeve 13 of the tail stock 3 is retracted to an intermediate position 10 along the arrow so that the placement center 6 of the tail stock 3 is no longer in pressure contact with the workpiece 5. . However, the rod part 27 of the pressure pin presses the workpiece 5 to the placement center 4 of the work spindles of the headstock 1 by the spring force of the spring element 22.
안정대(7)는 작업스핀들(30)의 배치센터(4)와 슬리이브(13)의 배치센터 (6)에 대하여 공작물(5)의 방사상 위치를 결정하여 준다. 심압대(3)의 배치센터(6)는 공작물의 취부중에 이루어진 중심배치상태가 흩으로짐이없이 중간위치로 후퇴될 수 있도록 한다. 이러한 이동은 공작물(5)이 더 이상 슬리이브(13)의 배치센터(6)에 접촉하지 않을 정도로 커서 공작물(5)이 센터(11A)에 접촉하지 않아야 한다. 따라서, 이러한 중간위치(10)로의 이동량은 십분의 일 밀리미터 이상이면 충분하다. 공작물(5)의 회전운동의 토크는 주축대(1)의 배치센터(4)에 의하여 전달되므로 공작물(5)은 힘(32)에 의하여 작업스핀들(30)의 배치센터(4)에 가압되어야 한다. 압력핀(21)은 롯드부분(21)을 통하여 이러한 마찰결합이 이루어질 수 있도록 한다. 이와 같이 함으로서, 공작물(5)은 회전구동되고 안정대(7)에 의하여 중심이 조절된 위치에 놓이므로 공작물(5)의 외주면에서 완전한 연마가 이루어질 수 있다. 이와 같이, 공작물 (5)의 심압대측 단부의 외주면이 공작물(5)에 부정확성, 즉 진원성 오차가 전달됨이 없이 연마될 수 있다.The stabilizer 7 determines the radial position of the workpiece 5 with respect to the placement center 4 of the work spindle 30 and the placement center 6 of the sleeve 13. The placement center 6 of the tail stock 3 allows the center arrangement state made during mounting of the workpiece to be retracted to an intermediate position without being scattered. This movement is such that the workpiece 5 no longer contacts the placement center 6 of the sleeve 13 so that the workpiece 5 should not contact the center 11A. Therefore, such movement amount to the intermediate position 10 is sufficient to be one tenth of a millimeter or more. Since the torque of the rotational movement of the work piece 5 is transmitted by the placement center 4 of the headstock 1, the work piece 5 must be pressed by the force 32 to the placement center 4 of the work spindle 30. do. The pressure pin 21 allows this frictional coupling to be made through the rod portion 21. By doing so, the workpiece 5 is rotationally driven and centered by the stabilizer 7 so that complete polishing can be achieved on the outer circumferential surface of the workpiece 5. In this way, the outer circumferential surface of the tailstock side end portion of the work piece 5 can be polished to the work piece 5 without inaccuracy, that is, a roundness error.
본 발명에 따른 방법과 이러한 방법을 수행하기 위한 장치에 의하여, 다른 취부시스템을 갖는 다른 선반에서의 적어도 한 작동시퀀스가 생략될 수 있고 이에 따라 가공코스트가 감소될 수 있다. 본 발명에 따른 방법과 이를 위한 장치는 공작물의 연마에만 한정되지 않고 다른 정밀가공작업이 이에 따라 수행될 수 있을 것이다.By means of the method according to the invention and the apparatus for carrying out such a method, at least one sequence of operations in different lathes with different mounting systems can be omitted and thus the processing cost can be reduced. The method according to the invention and the device therefor are not limited to the polishing of workpieces, but other precision machining operations may be performed accordingly.
