Abstract

PURPOSE: A device for exactly holding the center of a workpiece is provided to enable a user to obtain accurate concentricity of a workpiece by accurately chucking the workpiece. CONSTITUTION: A device for exactly holding the center of a workpiece comprises an outer portion(1) and an inner portion(2). The outer portion is a fixed portion. The inner portion keeps constant intervals from the outer portion. When the device moves forward, an inner shaft moves rearward so that forward pushing force is generated by a rear spring.

Description

공작물의 중심을 정확하게 잡아주는 장치{The device which takes structure center perfectly}The device which takes structure center perfectly}

본 발명은 축 등의 공작물을 척에 척킹 할 때 정확한 척킹을 할 수 있게 해주는 장치에 관한 것이다. The present invention relates to an apparatus that enables accurate chucking when chucking a workpiece such as an axis to a chuck.

일반적으로 기다란 축을 가공할 때 먼저 센타링 머신으로 양쪽 측면을 가공하고 기준이 되는 센타 를 센타드릴 로 가공을 하게 된다. 다음으로 터닝센타 등을 이용하여 센타링 머신으로 가공한 양 센타를 기준으로 하여 한쪽을 가공한다 .다음으로 나머지 부분을 가공 하게 되는데 센타를 그대로 두고 가공을 할 경우는 심압대 등을 사용하여 센타를 지지하여 가공을 하면 된다 . 그러나 한쪽 센타 부위를 가공해야 한다면 (내 경 가공 등) 공작물을 척킹 할 때 동심도 를 정확하게 하여 척킹 하는 것이 어렵게 된다 공작물의 무게가 무겁거나 길이가 길다면 더욱더 동심을 내기가 어렵게 된다. In general, when machining long shafts, both sides are first machined with a centering machine, and the reference center is machined with a center drill. Next, one side is processed on the basis of both centers processed by the centering machine using a turning center, etc. Next, the remaining part is processed. Support it and process it. However, if one center area needs to be machined (eg internal machining), it is difficult to chuck the workpiece with correct concentricity. If the workpiece is heavy or long, it will be more difficult to concentric.

본 발명은 공작물의 정확한 척킹 을 하게 하는데 그 목적이 있다.The object of the present invention is to allow accurate chucking of a workpiece.

본 발명은 고정되는 외측부분과 움직임이 있는 내측 부분으로 구성되고 내측 부분의 안쪽은 스프링의 힘으로 전후 동작을 하는 축이 들어있다. 이 장치를 센타의 중심에 이동 후 전진하면 내측 부분의 축은 뒤로 후퇴하면서 스프링에 의하여 앞쪽으로 밀어내는 힘이 발생한다 이 상태에서 공작물을 고정하고 있던 척을 풀었다 조이는 동작을 한다.이때 고정되는 외측부와 움직임이 있는 내측부는 공간이 있어 닿지 않게 되고 힘을 받는 부위는 뒷쪽 의 중심부분으로 최소화하여 정확하게 동심을 잡아 척킹을 할 수 있게 하는데 특징이 있다.The present invention is composed of a fixed outer portion and a moving inner portion and the inner portion of the inner portion contains a shaft that moves back and forth by the force of the spring. If the device is moved to the center of the center and moved forward, the inner shaft will retreat and the force will be pushed forward by the spring.In this state, the chuck holding the workpiece is loosened and tightened. The inner part with the movement is spaced so that it cannot be touched, and the area under the force is minimized to the center of the back so that it can be precisely concentrically chucked.

본 발명은 공작물의 정확한 척킹을 가능하게 함으로써 공작물의 아주 정밀한 동심도를 얻을 수 있다.The present invention enables accurate chucking of the workpiece, thereby obtaining very precise concentricity of the workpiece.

본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention will now be described in detail with reference to the accompanying drawings.

도(2)는 도(1)의 A부위의 상세도로서 볼과 (5)와(6)사이는 공간이 있어 움직임이 자유롭다 볼의 반지름보다 (6)의 중심에 있는 반지름이 크다 따라서 볼이 뒤쪽으로 미는 힘이 작용하면 밀착되는 부위는 한점으로 이루어진다.Fig. 2 is a detailed view of the A portion of Fig. 1, with a space between the ball and (5) and (6), which allows freedom of movement. The radius at the center of (6) is greater than the radius of the ball. When this pushing force is applied to the back, one point of contact is made.

도(1) 을 상세히 설명하면 (1)은 고정 부위로서 기계의 공구대 등에 부착되 고 고정되어 진다 (2)는 움직임이 있는 부위로서 (1)이 공작물의 센터의 중심으로 이동 후 전진동작을 하게 되면 (3)은 뒤쪽으로 후진을 한다 이때(7)의 스프링의 힘을 받아 (3)은 앞쪽으로 미는 힘이 생기게 된다 이때 공작물을 잡고 있던 척 이나 가타 고정장치의 고정을 해제한 후 다시 고정을 한다. 이때 (2)는 (1)과 공간이 있어 간섭을 전혀 받지 않게 된다. 축의 직각 방향으로 작용하는 힘은 없어지고 도(2)의 상세도에서 (6)의 반지름부위의 한점에만 힘이 작용을 한다.따라서 축의중심으로만 힘이 작용을 하여 정확한 동심을 얻을 수 있는 것이다.Referring to Fig. 1 in detail, (1) is a fixed part, which is attached to a tool stand of a machine, and is fixed. (2) is a moving part (1) which moves forward to the center of the workpiece. (3) retreats backward. At this time, (3) is pushed forward by the spring force. (3) Release the chuck or other fixing device that is holding the workpiece and then fix it again. Do it. In this case, (2) has a space with (1) so that it does not receive any interference at all. The force acting in the direction perpendicular to the axis disappears, and the force acts only on one point of the radius part in (6) in the detail of Fig. (2). .

축 가공에 있어서 정확한 동심으로 척킹을 함으로서 척킹 불량으로 인한 불량을 없앨 수 있다.In axial machining, chucking can be eliminated by correct concentricity.

도 1은 정확한 척킹 을 하게 하는 장치이다.1 is a device that allows accurate chucking.

도 2는 도 1의 A 부위의 상세도이다.FIG. 2 is a detailed view of portion A of FIG. 1.

도 3은 실제 가공적용 예로서 (1)은 센타링 머신으로 센타링 작업을 한 상태이고 (2)는 1차 선삭을 한 상태이고 (3)은 완성품(4) 를 가공하기 위해 척킹을 할때 정확한 동심을 위해 본 발명품을 실제 사용 예이다.Figure 3 is a practical application example (1) is the centering work with the centering machine (2) is the state of the first turning and (3) when chucking to process the finished product (4) This invention is an example of practical use for accurate concentricity.
