본 고안은 선반에서 공작물을 가공하기 위해 공작물을 고정하는데 사용되는 척(chuck)에 관한 것이다.The present invention relates to a chuck used to hold a workpiece for machining the workpiece on a lathe.
선반은 면깍기, 구멍뚫기 및 탭내기등 복합적인 작업을 동시에 할 수 있는데, 이러한 선반에서 가공하고자 하는 공작물을 고정하는 척으로서, 3조 연동축(Universal chuck) 또는 4조 독립척(Independent chuck)이 일반적으로 사용되고 있다. 3조 연동척의 경우, 각각의 조(jaw)가 서로 120°의 각도를 이룬 상태에서, 중심을 향하여 조가 연동되어 공작물을 압착고정시키는 것으로, 동시에 조가 연동되므로서 센터를 맞추는 것이 용이하고, 단시간에 개폐하는 것이 용이한 장점이 있다. 하지만, 불규칙한 공작물을 무리하게 결합시키면 정밀도가 저하된다는 문제가 있었고, 또한 원형 또는 구형의 공작물인 경우, 특히 구형 공작물의 경우, 센터를 맞춘 상태에서 형성되는 X-Y축상의 평면과 수직인 Z축상의 평면만을 가공할 수 있으므로, 다른 면을 가공하기 위해서는 압착고정을 풀고, 가공면을 고려하여 다시 센터를 맞춘상태에서 가공위치를 고정시켜 밀링기로 면을 깍아내고, 기타의 기계장치로 구멍을 뚫고, 탭을 내는 방법을 사용하는 해야만 문제가 있었다.Lathes can carry out complex tasks such as face mowing, drilling and tapping at the same time.The chucks that hold the workpieces to be machined on these lathes are either a universal chuck or an independent chuck. This is commonly used. In the case of a three-joint interlocking chuck, the jaws are interlocked toward the center with each jaw at an angle of 120 ° to crimp the workpiece. It is easy to open and close. However, there is a problem in that precision is reduced by forcibly joining irregular workpieces, and in the case of round or spherical workpieces, especially spherical workpieces, a plane on the Z axis perpendicular to the plane on the XY axis formed in the centered state. Since only the surface can be machined, loosen the clamping fixing in order to process the other side, and fix the surface with the milling machine by fixing the machining position while re-centering in consideration of the processing side, and drilling holes with other machinery, and tapping I had to use the method of paying for the problem.
또한, 선반에 있어서, 구의 경우 6면 가공을 위하여, 4조의 독립척을 사용하였지만, 이 경우에는 위치설정을 위해 서로 직각인 2개의 독립조를 사용하고, 압착용으로 그에 대응하는 2개의 독립조를 사용해야 하는데 압착용으로 사용되는 2개의 독립조를 번갈아 조여야 하는 불편함이 있었다. 더우기, 면의 가공에 있어서, 서로 직각인 6면 가공만이 있는 것이 아니고, 때에 따라서는 임의 각도의 임의면 가공의 경우, 이에 대응하기가 곤란하였다.In the lathe, in the case of the sphere, four sets of independent chucks were used for six-side machining, but in this case, two independent pairs of right angles to each other were used for positioning, and two independent pairs corresponding to each other for pressing. There was an inconvenience of having to alternate between two independent tanks used for pressing. In addition, in the processing of the surface, not only the six-side processing that is orthogonal to each other, but also sometimes in the case of the arbitrary surface processing of any angle, it was difficult to cope with this.
따라서, 본 고안은 이에 따라 안출된 것으로, 2개의 압착조를 갖는 4조 독립척보다 간편한 3조 독립척을 제공하는 것을 목적으로 하는 것이다.Accordingly, the present invention has been devised in accordance with the present invention, and an object of the present invention is to provide a three-piece independent chuck which is simpler than a four-piece independent chuck having two compression tanks.
또한, 본 고안의 다른 목적은, 위치설정용 2조의 압착면을 각도 조정이 가능한 가변각 압착면으로 한 3조 독립척을 제공하는 것이다.In addition, another object of the present invention is to provide a three-piece independent chuck having a variable angle crimp surface capable of adjusting the angle of the two-compression surface for positioning.
본 고안에 따른 3조 독립척은, 서로 직각인 2개의 위치설정조와, 이러한 위치설정조에서 둔작으로 위치한 하나의 독립압착조로 구성되며, 또한 위치설정조의 압착면을 각조조절이 가능한 구조로 하는 것을 특징으로 한다.The three tank independent chuck according to the present invention is composed of two positioning tanks perpendicular to each other, and one independent crimping tank located in a small position in such a positioning tank, and the compression surface of the positioning tank has a structure capable of adjusting the angle of the nail. It features.
이와같은 본 고안 3조 독립척에 의해, 하나의 독립조만을 조이므로서 압착이 편리하고, 임의 각도의 임의의 면에 대응하여 위치설정조의 압착면의 각도를 조정하므로서 우수한 압착력이 제공된다.By the three-unit independent chuck of the present invention, the crimping is convenient while tightening only one independent tank, and the superior pressing force is provided by adjusting the angle of the pressing surface of the positioning tank corresponding to any surface of any angle.
이하, 본 고안 3조 독립척에 대해 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the drawings will be described in detail with respect to the invention 3 set chuck.
제1도는 본 고안 3조 독립척의 정면도이다. 본 고안의 3조 독립척(1)은 서로 직각인 2개의 위치설정조(2)(3)와, 이러한 위치설정조(2)(3)에 둔각, 예를들면 135°로 위치하는 하나의 압착조(4)로 구성된다. 공작물의 형상과 가공면에 따라, 위치설정조(2)(3)를 이동고정하여 위치를 설정한 후, 피니언기어에 렌치를 끼워서 돌리면 압착조(4)가 공작물에 압착되어, 공작물이 견고하게 고정된다.1 is a front view of the third invention independent chuck. The three sets of independent chucks 1 of the present invention have two positioning tanks 2 and 3 which are perpendicular to each other, and one positioned at an obtuse angle, for example, 135 °, in such positioning tanks 2 and 3. It consists of the crimping tank 4. According to the shape and processing surface of the workpiece, the positioning tank 2 and 3 are moved to set the position. Then, by inserting a wrench into the pinion gear and turning it, the crimping tank 4 is squeezed to the workpiece and the workpiece is firmly secured. It is fixed.
제2도 및 제3도는 본 고안 3조 독립척에 사용되는 위치설정용 조(2)(3)를 도시하는데, 위치설정용 조(2)(3)는 삽입홈(11)과, 이 삽입홈(11)을 관통하는 구멍(9) 및 피니언이 일부 형성된 조본체(5)와, 압착면(13)과 렉부(14)로 이루어져서, 위에서 보아 T자 형상을 한 압착부재(6)와, 조본체(5)의 구멍(9)과 렉부(14)의 반경중심에 형성된 구멍(8)을 관통하여 조본체(5)와 압착부재(6)를 결합하는 핀(10) 및 압착부재(6)의 렉부(14)와 맞물리도록 조본체(5)의 상부면에서 비스듬하게 삽입된 피니언(12)으로 구성된다. 삽입홈(11)에는 지지홈(15)이 형성되어, 제4도에 도시된 바와 같이, 피니언(12)이 일단부가 회전가능하게 결합된다.2 and 3 show a positioning jaw (2) (3) to be used for the three independent chuck of the present invention, the positioning jaw (2) (3) is the insertion groove 11 and the insertion A crimping member (6) formed of a coarse body (5) formed with a hole (9) and a pinion (through the groove (11)) and a crimping surface (13) and a rack portion (14), which have a T-shape as viewed from above; A pin 10 and a crimping member 6 which pass through the hole 9 of the jaw body 5 and the hole 8 formed at the radial center of the rack portion 14 to couple the jaw body 5 and the crimping member 6 to each other. It is composed of a pinion (12) inserted obliquely at the upper surface of the main body (5) to engage the rack portion 14 of the). Insertion groove 11 is formed with a support groove 15, as shown in Figure 4, the pinion 12 is rotatably coupled to one end.
제4도는 제2도의 A-A선 단면을 도시하는 것으로, 피니언(12)을 회전하여, 일점쇄선으로 도시된 바와 같이 압착면(13)의 각도를 조절하므로서 임의 각도의 임의면을 가공한다.4 is a cross-sectional view taken along the line A-A of FIG. 2, and the pinion 12 is rotated to process any surface of an arbitrary angle by adjusting the angle of the pressing surface 13 as shown by the dashed-dotted line.
