본 고안은 챔퍼 측정장치에 관한 것으로서, 특히 챔퍼량을 측정함에 있어 간접 측정하여 계산하지 않고도 직접 측정이 가능한 챔퍼(chamfer) 측정장치에 관한 것이다.The present invention relates to a chamfer measuring device, and more particularly to a chamfer measuring device that can be directly measured without indirect measurement in calculating the amount of chamfer.
일반적으로 엔진부품의 코너부위나, 각종 기계요소, 리이머, 탭등은 소정각도의 챔퍼량에 따라 그 기능이 더 좋아지거나 또는 열화되게 되는 것이 일반적이므로 정확한 챔버량의 측정이 필요하다.In general, the corner portion of the engine parts, various mechanical elements, reamers, taps, etc. are generally better or deteriorated according to the chamfer amount of a predetermined angle, so accurate measurement of the chamber amount is necessary.
챔퍼량을 측정하기 위해서 종래에서는, 제1도에 도시된 바와 같이 버어니어 캘리퍼스 등의 측정공구로 제품(10)의 경사진면 즉, 대각선 길이(L)를 측정하여 그 길이(L)를 다음식(a)에 대입함으로써 챔퍼량, 즉 C1, C2를 구할 수 있었다.In order to measure the amount of chamfers, conventionally, as shown in FIG. 1, the inclined surface of the product 10, that is, the diagonal length L, is measured with a measuring tool such as a vernier caliper, and the length L is determined. By substituting food (a), the amount of chamfers, namely, C1 and C2, was obtained.
하지만 종래 챔퍼량 측정에 있어서는, 버어니어 캘리퍼스 등의 측정 공구로 경사면 길이를 재는 것이어서 정확성이 떨어지며, 경사각 θ값을 정확히 알고 식 ⓐ에 대입하는 것이 아니라 경사각 θ값을 가정하여 대입하는 것이어서 그 측정값이 정확하지 못한 것이다.However, in the conventional chamfer amount measurement, it is less accurate to measure the inclined surface length with a measuring tool such as a vernier caliper, and it is to substitute the assumption of the inclination angle θ value rather than knowing the inclination angle θ value accurately and substituting it into the equation ⓐ. This would not be accurate.
상기와 같이 종래의 챔퍼 측정은 챔퍼량을 직접 측정 못하고 간접 측정하는 것이어서 이에따라 계산이 필요한 것이며 경사각 θ값을 가정하는 것이고, 또한 버어니어 캘리퍼스 등의 측정공구로 경사면 길이를 재는 것이어서 챔퍼량의 측정값이 부정확함에 따라, 상기 챔퍼량을 갖게되는 각종 기계요소 또는 공구의 기능을 열화시키는 문제점이 있었다.As described above, the conventional chamfer measurement is not an direct measurement of the chamfer amount, but an indirect measurement. Therefore, calculation is required accordingly, and an inclination angle θ value is assumed. Also, a chamfer length is measured by a measuring tool such as a vernier caliper to measure the chamfer amount. As a result of this inaccuracy, there has been a problem of degrading the function of various mechanical elements or tools having the chamfer amount.
본 고안은 상기와 같은 종래 챔퍼측정의 문제점을 감안하여 안출된 것으로서 챔퍼량을 직접 측정할 수 있으며, 또한 경사각 θ값을 정확하게 측정할 수 있도록 한 챔퍼측정장치를 제공함에 그 목적이 있다.The object of the present invention is to provide a chamfer measuring device that can measure the amount of chamfers directly, and can also accurately measure the inclination angle θ value in view of the problems of the conventional chamfer measurement as described above.
상기 목적을 달성하기 위하여 본 고안은, 주척과 상기 주척의 일측면으로부터 직각 방향으로 소정길이 연장된 보조척을 가지는 T자형 모척과, 상기 주척을 따라 슬라이딩 가능하게 설치되며, 그 단부가 소정각도로 경사진 자척을 구비하여 된 것을 특징으로 한다.In order to achieve the above object, the present invention, the T-shaped chuck having a main chuck and an auxiliary chuck extending a predetermined length in a direction perpendicular to one side of the main chuck, and slidably installed along the main chuck, the end of which is at a predetermined angle Characterized in that it is provided with an inclined magnetic chuck.
이하 본 고안에 따른 챔퍼 측정장치의 바람직한 일 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of a chamfer measuring apparatus according to the present invention will be described in detail with reference to the accompanying drawings.
제2a도, 제2b도는 본 고안에 따른 챔퍼측정장치를 도시한 것으로서, 모척(1)은, 소정간격의 눈금이 매겨져있는 주척(1a)과, 상기 주척의 일측면으로 부터 직각방향으로 소정길이 연장되며 소정간격의 눈금이 매겨져 있는 보조척(1b)으로 이루어진다. 상기 주척(1a)과 보조척(1b)은 서로의 눈금이 영점 조정된 상태이며 상기 주척(1a)에는 가이드 홈(1c)이 마련되고, 상기 가이드 홈(1c)에는 그 일측에 돌기부(2a)가 돌출되게 설치되며 그 타측에 소정간격의 눈금이 매겨져 자척(2)이 슬라이딩 가능하게 결합된다. 상기 자척(2)의 일끝단은 소정각도의 경사진면을 가지며, 상단에는 고정나사(2b)가 마련되어 상기 주척(1a)에 대하여 자척(2)을 위치 고정시킬 수 있도록 되어 있다.2a and 2b show a chamfer measuring device according to the present invention, the master chuck 1, the main chuck (1a) is a graduation of a predetermined interval and a predetermined length in a direction perpendicular to one side of the main chuck. It consists of an auxiliary chuck 1b that is extended and graduated at predetermined intervals. The main chuck (1a) and the auxiliary chuck (1b) is a state in which the scale of each other is zero-adjusted, the guide chuck (1c) is provided in the main chuck (1a), and the projection (2a) on one side of the guide groove (1c) Is installed to protrude and the graduations of the predetermined interval on the other side is attached to the magnetic chuck 2 is slidably coupled. One end of the magnetic chuck 2 has an inclined surface at a predetermined angle, and a fixing screw 2b is provided at an upper end thereof to fix the magnetic chuck 2 with respect to the main chuck 1a.
상술한 바와 같이 본 고안에 따른 챔퍼 측정장치는, 측정하고자 하는 제품(3)에 제2도에 도시된 바와 같이 모척(1)의 주척(1a)과 보조척(1b)을 밀착시킨 다음, 주척(1a)의 가이드 홈(1c)을 따라 자척(2)을 슬라이딩 이송시켜 상기 자척(2)의 경사진 일끝단을 제품(3)의 경사면에 밀착시키고 자척(2)이 주척(1a)에 대해 유동되지 않도록 고정나사(2b)로써 위치 고정시킨다.As described above, in the chamfer measuring device according to the present invention, the main chuck 1a and the auxiliary chuck 1b of the mother chuck 1 closely adhere to the product 3 to be measured, as shown in FIG. The magnetic chuck 2 is slid along the guide groove 1c of (1a) so that the inclined end of the magnetic chuck 2 is brought into close contact with the inclined surface of the product 3, and the magnetic chuck 2 with respect to the main chuck 1a. The position is fixed by the fixing screw 2b so as not to flow.
상기 자척(2)은, 제품(3)의 경사각도에 따라 30˚또는 45˚의 경사진 일끝단을 갖는 2가지 형태가 사용된다. 이것은 대부분의 챔퍼 각도가 30˚또는 45˚의 것이 사용되기 때문이며 제품의 특성상 여러 각도로 경사진 자척(2)의 사용될 수도 있다.The magnetic chuck 2 is used in two forms having one end inclined at 30 ° or 45 ° depending on the inclination angle of the product 3. This is because most of the chamfer angle of 30 ° or 45 ° is used and may be used of the magnetic chuck 2 inclined at various angles due to the characteristics of the product.
상기와 같이 제품(3)에 챔퍼측정장치를 장착한 후 주척(1a)과 보조척(1b) 및, 자척(2)의 눈금을 읽음으로써 0.05㎜까지 챔퍼량 측정이 가능하다. 또한, 상기와 같이 측정한 챔퍼량 값을 다음식 ⓑ에 대입함으로써 경사각 θ값도 정확하게 산출할 수 있다.After the chamfer measuring device is attached to the product 3 as described above, the chamfer amount can be measured up to 0.05 mm by reading the scales of the main chuck 1a, the auxiliary chuck 1b, and the magnetic chuck 2. In addition, the inclination angle θ value can also be accurately calculated by substituting the chamfer amount value measured as described above in the following equation (ⓑ).
상술한 바와 같이 본 고안에 따른 챔퍼 측정장치에 의하며, 주척, 보조척으로 이루어진 모척과 끝단이 경사진 자척에 의해 계산을 하지 않고도 정확한 챔퍼량을 직접 읽을 수 있으며 이에따라 경사각 θ값을 가정하지 않고도 정확하게 산출할수 있는 것이어서, 챔퍼량의 정도에 의해 기능이 좌우되는 여러 기계요소 또는 공구들의 기능이 열화되는 것을 방지할 수 있다.According to the chamfer measuring device according to the present invention as described above, the chamfer and the end consisting of the main chuck, the auxiliary chuck can read the exact chamfer directly without calculation by the inclined magnetic chuck, and accordingly, without accurately assuming the inclination angle θ value Since it can be calculated, it is possible to prevent deterioration of the functions of various mechanical elements or tools whose function depends on the degree of the chamfer amount.
