Description

내경구 측정 장치{Measuring apparatus for inside globe}Measuring apparatus for inside globe

본 발명은 내경구 측정 장치에 관한 것으로서, 더욱 상세하게는 피측정물의 내경을 갖는 공간부에 대한 가공정밀도를 측정하는 내경구 측정 장치에 관한 것이다.The present invention relates to an internal diameter measuring device, and more particularly, to an internal diameter measuring device for measuring the processing precision for the space portion having the internal diameter of the object to be measured.

일반적으로 공작물에 형성되어 있는 공간부의 내경은 내경 마이크로미터나 실린더 게이지 등을 사용하여 측정하고 있다. 상기와 같은 장비는 공작물에 형성된 공간부의 내경을 측정하기 위한 것으로, 측정을 위하여는 공간부의 길이가 일정 크기 이상이어야 하며, 또한 측정시 상기 장비가 반드시 공간부내로 들어갈 수 있어야만 측정이 가능하게 된다.Generally, the internal diameter of the space part formed in the workpiece | work is measured using the internal diameter micrometer, a cylinder gauge, etc. Such equipment is for measuring the inner diameter of the space portion formed in the workpiece. For the measurement, the length of the space portion must be greater than or equal to a certain size, and the measurement can be performed only if the equipment can enter the space portion during measurement.

따라서, 공간부의 깊이가 일정 크기 이하이거나, 측정시 장비가 공작물에 형성된 공간부로 들어갈 수 없는 경우에는 상기 공간부의 내경을 정확하게 측정할 수가 없게 된다.Therefore, when the depth of the space portion is equal to or less than a certain size or when the equipment cannot enter the space portion formed in the workpiece during measurement, the inner diameter of the space portion cannot be accurately measured.

더군다나, 공작물에 형성된 공간부의 내부에 또다른 공간부를 구비하고 있을 경우, 그 공간부의 내경을 상기 장비를 사용하여 직접 측정하기란 매우 힘들다 하겠다.Furthermore, when another space is provided inside the space formed on the workpiece, it is very difficult to directly measure the inner diameter of the space using the above equipment.

한편, 도 6은 종래의 보어측정용 다이얼 게이지를 나타내는 도면으로서, 다이얼 게이지(10)의 일측을 손잡이(12)를 구비한 연결대(14)로 길게 연결하고, 연결대(14)의 단부에 T형 측정안내블록(16)을 형성하고, 이에 다이얼 게이지(10)와 연결된 측정자(18)를 설치하여 구성된다.On the other hand, Figure 6 is a view showing a conventional dial gauge for bore measurement, one side of the dial gauge 10 is connected to the connecting rod 14 having a handle 12 long, T-shaped at the end of the connecting table 14 Forming the measuring guide block 16, it is configured by installing a measuring instrument 18 connected to the dial gauge (10).

이때, 상기 측정안내블록(16)이 피측정물에 가공된 보어 내로 위치되어 상기 측정자(18)가 보어에 접촉되면서 측정이 이루어져 그 측정값을 다이얼 게이지(10)에 전달함으로써 측정값을 읽게 되는 것이다. 이에 따라 보어의 불량 여부를 판단하게 된다.At this time, the measurement guide block 16 is located in the bore machined to the object to be measured so that the measuring device 18 is in contact with the bore and the measurement is transmitted to the dial gauge 10 to read the measured value. will be. Accordingly, it is determined whether the bore is defective.

그러나, 상기 측정안내블록은 손잡이를 구비한 연결대와 연결되어, 사용자가 손잡이를 손으로 잡고 피측정물에 집어넣어 측정하게 되므로 보어의 내경 측정시 흔들림이 발생할 수 있고 측정부위와 측정자의 접촉이 원활하게 이루어지지 않을 가능성이 있다.However, the measurement guide block is connected to the connecting rod having a handle, so that the user is holding the handle by hand and inserting it into the object to be measured, the shaking may occur when measuring the bore of the bore and the contact between the measuring part and the measuring device is smooth. It may not be possible.

또한, 종래의 내경게이지나 실린더 게이지는 내경이 일정한 경우에 측정가능하나, 내부에 구형상의 공간부를 가공하였을 경우 진구도(구의 정밀도)를 측정하지는 못하는 문제점이 있다.In addition, although the conventional inner diameter gauge or cylinder gauge can be measured when the inner diameter is constant, there is a problem in that the spherical degree (sphere precision) cannot be measured when a spherical space part is processed inside.

본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 탐침체가 몸체에 상하방향으로 이동가능하게 스프링을 설치하고, 베이스블럭이 피측정물의 내경측에 끼워짐으로 몸체가 피측물에 고정된 상태에서 다이얼게이지를 이용하여 임의의 깊이지점에서 피측정물의 내경 차이를 측정가능하게 함으로써, 피측정물 내부의 진구도를 정확하게 측정할 수 있도록 한 내경구 측정 장치를 제공하는데 그 목적이 있다.The present invention has been made in view of the above point, the probe body is installed in the spring to move in the vertical direction to the body, the base block is fitted to the inner diameter side of the object to be measured, the body is fixed to the object It is an object of the present invention to provide an internal oral measurement device capable of accurately measuring the sphericity of an object under measurement by enabling the measurement of an inner diameter difference of an object under an arbitrary depth using a dial gauge at.

상기한 목적을 달성하기 위한 본 발명은 내부에 구면이 형성된 공간부를 갖는 피측정물의 내경을 측정하는 내경구 측정 장치에 있어서,In the present invention for achieving the above object is an internal diameter measuring device for measuring the internal diameter of the object to be measured having a space portion formed therein,

바람직한 구현예로서, 상기 피측정물에 내경측에 삽입되어 몸체가 고정될 수 있도록 상기 몸체의 타단부에 설치된 베이스블럭을 포함하고, 상기 연결대가 베이스블럭을 관통하여 상하방향으로 슬라이드 가능하게 지지되는 것을 특징으로 한다.In a preferred embodiment, the base block is inserted into the inside of the measured object to include a base block installed on the other end of the body so that the body is fixed, the connecting rod is slidably supported in the vertical direction through the base block It is characterized by.

더욱 바람직한 구현예로서, 상기 연결대의 하단부에는 연결대의 길이방향에 대해 수직방향으로 플랜지부가 형성되고, 상기 플랜지부의 하부에서 수직방향으로 제1연결관이 돌출형성되고, 상기 제1연결관과 연결되도록 다이얼게이지에서 수직방향으로 제2연결관이 돌출형성되며, 상기 제1연결관과 제2연결관이 슬라이드 가능하게 결합되어 연결대가 몸체에서 상하방향으로 움직이는 것을 특징으로 한다.In a more preferred embodiment, the lower end of the connecting rod is formed with a flange portion in the vertical direction with respect to the longitudinal direction of the connecting rod, the first connecting pipe is formed projecting in the vertical direction from the lower portion of the flange portion, connecting with the first connecting pipe The second connecting pipe is formed to protrude from the dial gauge in a vertical direction, and the first connecting pipe and the second connecting pipe are slidably coupled so that the connecting rod moves up and down in the body.

이에 따라 본 발명에 따른 내경구 측정 장치에 의하면, 다이얼게이지가 장착된 몸체에 탐침체가 스프링을 통해 이동가능하게 설치됨으로써, 스프링에 의해 측정부위에 대한 탐침체의 밀착성을 향상시킬 수 있고, 몸체의 상단에 베이스블럭을 설치하여 베이스블럭이 피측정물의 내경측에 끼워짐으로 고정된 상태에서 피측정물의 내경 차이를 정확하게 측정할 수 있다.Accordingly, according to the internal diameter measuring device according to the present invention, the probe body is installed to be movable through the spring on the body equipped with the dial gauge, thereby improving the adhesion of the probe body to the measurement site by the spring, the body By installing a base block at the top of the base block can be accurately measured the difference in the inner diameter of the measured object in the state that the base block is fixed to the inner diameter side of the object to be measured.

또한, 상기 탐침체를 원주방향으로 회전시킴에 따라 반경방향으로 여러 위치에서 피측정물의 내경 차이를 측정함으로써, 진원도 또는 진구도를 측정할 수 있다.In addition, as the probe body rotates in the circumferential direction, the roundness or the sphericity can be measured by measuring the difference in the inner diameter of the object under various positions in the radial direction.

이하, 본 발명의 바람직한 실시예를 첨부도면을 참조로 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부한 도 1은 본 발명의 일실시예에 따른 내경구 측정 장치를 나타내는 사시도이고, 도 2는 도 1의 정면도이고, 도 3은 도 1의 측면도이고이다.1 is a perspective view illustrating an internal oral measurement device according to an embodiment of the present invention, FIG. 2 is a front view of FIG. 1, and FIG. 3 is a side view of FIG. 1.

일반적으로 내경이 일정한 원통은 마이크로미터나 내경게이지를 사용하여 내경을 측정가능하나, 내부에 구형상을 가공했을 때, 진구도(구의 정밀도)를 측정할 수 있는 게이지는 없다.In general, a cylinder with a constant internal diameter can measure the internal diameter using a micrometer or an internal diameter gauge, but when measuring the spherical shape inside, there is no gauge that can measure the sphericity (sphere precision).

본 발명은 내부에 구형상의 공간부(21)를 갖는 피측정물(20)의 진구도를 측정할 수 있도록 한 점에 주안점이 있다.The present invention has a main point in that the sphericity of the measurement object 20 having a spherical space portion 21 therein can be measured.

상기 공간부(21)는 깊이에 따라 직경이 좁아졌다가 다시 넓어지게 형성되어 있고, 피측정물(20)의 하부 내경측에 베이스블럭(22)이 삽입될 수 있는 수용공간이 마련되어 있다.The space 21 has a diameter narrowed according to depth and widened again, and an accommodation space into which the base block 22 can be inserted is provided at the lower inner diameter side of the object 20.

본 발명의 일실시예에 따른 탐침체(23)는 상기 공간부(21)의 임의 지점의 깊이에서 진구도를 측정할 수 있다.Probe body 23 according to an embodiment of the present invention can measure the sphericity at the depth of any point of the space portion 21.

즉, 상기 탐침체는 깊이방향(축방향)을 기준으로 회전각에 따라 구의 형태가 왜곡(흔히 '짱구'라 함)되어 있다면, 탐침체가 접촉하기 위한 깊이가 달라지므로, 회전각에 따라 내경 차이를 알 수 있다. In other words, if the shape of the sphere is distorted (commonly referred to as "ball balls") according to the rotation angle based on the depth direction (axial direction), the probe body has a different depth for contact, so the inner diameter depends on the rotation angle. You can see the difference.

여기서, 상기 탐침체(23)는 연결대(24)를 통해 다이얼게이지(25)에 고정되지 않고, 베이스블럭(22)를 통해 좌우방향으로 움직이지 않도록 지지하면서 스프링(26)에 의해 피측정물(20)의 깊이방향으로 이동가능하게 설치됨으로써, 공간부(21)의 구면에서 깊이방향으로 임의의 지점에서 내경 차이를 측정할 수 있게 된다.Here, the probe body 23 is not fixed to the dial gauge 25 through the connecting table 24, and is supported by the spring 26 while being supported so as not to move left and right through the base block 22. By being movable in the depth direction of 20, it is possible to measure the difference in inner diameter at any point in the depth direction from the spherical surface of the space portion 21.

즉, 상기 탐침체(23)는 근사 장방형의 직사각체로서 수평방향으로 형성되고, 탐침체(23)의 양단부에는 수평방향으로 돌기가 형성되어 있으며, 연결대(24)는 직 사각체의 중심부에서 하방향으로 수직하게 설치되어 탐침체(23)와 연결대(24)는 "T"자형을 이루도록 되어있다.That is, the probe 23 is formed in a horizontal direction as an approximate rectangular rectangle, and protrusions are formed at both ends of the probe 23 in the horizontal direction, and the connecting table 24 is disposed at the center of the rectangular rectangle. It is installed vertically in the direction so that the probe 23 and the connecting table 24 to form a "T" shape.

상기 연결대(24)의 하단부에는 플랜지부(27)가 반경방향으로 형성되어 있고, 상기 연결대(24)의 일부가 일측에 다이얼게이지(25)를 갖는 몸체(28)의 내부에 삽입되어 상하방향으로 슬라이드가능하게 설치된다.Flange 27 is formed in the lower end portion of the connecting rod 24 in a radial direction, and a portion of the connecting rod 24 is inserted into the inside of the body 28 having the dial gauge 25 on one side and is moved upward and downward. It is slidably installed.

상기 몸체(28)는 원통형태이며, 내부에 연결대(24)의 플랜지부(27)가 상하방향으로 이동가능하도록 플랜지부(27) 하부를 탄성지지하도록 설치된 스프링(26)을 갖는다. 또한, 몸체(28)의 하단부에는 다이얼게이지(25)가 설치되고, 몸체(28)의 상단부에는 베이스블럭(22)이 고정설치되어 있다.The body 28 has a cylindrical shape and has a spring 26 installed therein to elastically support a lower portion of the flange portion 27 so that the flange portion 27 of the connecting table 24 is movable upward and downward. In addition, the dial gauge 25 is installed at the lower end of the body 28, the base block 22 is fixed to the upper end of the body 28.

이때, 베이스블럭(22)은 소직경부와 대직경부로 구성되고, 베이스블럭(22)의 중심부에는 연결대(24)가 관통할 수 있도록 관통홀이 형성되어 연결대(24)가 베이스블럭(22)에 의해 좌우방향으로 흔들림없이 상하방향으로 슬라이드 가능하게 한다.At this time, the base block 22 is composed of a small diameter portion and a large diameter portion, the through hole is formed in the center of the base block 22 so that the connecting rod 24 can penetrate the connecting rod 24 to the base block 22 This makes it possible to slide in the vertical direction without shaking in the horizontal direction.

상기 연결대(24)가 상하방향으로 슬라이딩될 수 있도록 유도하기 위해 플랜지부(27)의 하단에서 하방향으로 제1연결관(29)이 돌출형성되고, 다이얼게이지(25)와 연결되도록 상방향으로 제2연결관(30)이 돌출형성되어 있다.The first connecting pipe 29 protrudes downward from the lower end of the flange portion 27 to guide the connecting rod 24 to slide upward and downward, and upwards to be connected to the dial gauge 25. The second connecting pipe 30 is protruded.

상기 제2연결관(30)은 제1연결관(29)의 내부에 삽입되어 연결대(24)가 상항방향으로 슬라이딩되는 것을 유도한다.The second connecting pipe 30 is inserted into the first connecting pipe 29 to induce the connecting table 24 to slide upward.

이와 같은 구성에 의한 본 발명의 일실시예에 따른 내경구 측정 장치의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the inner diameter measuring device according to an embodiment of the present invention by such a configuration as follows.

도 4는 피측정물의 내경 측정을 위해 장착된 도 1의 내경 측정장치를 나타내는 단면도이고, 도 5는 도 1의 단면도이다.4 is a cross-sectional view illustrating the inner diameter measuring apparatus of FIG. 1 mounted to measure an inner diameter of a measurement target, and FIG. 5 is a cross-sectional view of FIG. 1.

먼저, 베이스블럭(22)의 소직경부를 피측정물(20)의 하부 수용공간에 끼워 고정하게 되면, 탐침체(23)와 연결대(24)의 하부를 받치고 있는 스프링(26)이 연결대(24)의 플랜지부(27)를 상방향으로 밀어 올림에 따라 연결대(24)가 상방향으로 이동하면서 탐침체(23)가 피측정물(20)의 공간부(21)에 밀착되게 된다.First, when the small diameter portion of the base block 22 is fixed to the lower receiving space of the measurement object 20, the spring 26 supporting the probe 23 and the lower portion of the connecting table 24 is connected to the connecting table 24. As the connecting portion 24 moves upward as the flange portion 27 of the) is pushed upward, the probe body 23 comes into close contact with the space 21 of the object 20 to be measured.

상기 스프링(26)은 탐침체(23)를 밀어서 탐침체(23)가 피측정물(20)의 공간부(21)에 접촉할 수 있도록 도와주고, 만약 구의 형태가 왜곡된 경우 탐침체가 접촉하기 위한 깊이가 달라지므로 각 방향의 내경 차이를 알 수 있게 되어 진구도를 측정할 수 있다.The spring 26 pushes the probe body 23 to help the probe body 23 come into contact with the space 21 of the object 20, and if the shape of the sphere is distorted, the probe body comes into contact. Since the depth is different, it is possible to know the difference in the inner diameter in each direction, so that the sphericity can be measured.

상기 베이스블럭(22)은 피측정물(20)의 내경측에 고정됨으로써, 연결대(24)가 피측정물(20)의 공간부(21)의 중심축선을 따라 안정적으로 이동할 수 있도록 유도해 준다.The base block 22 is fixed to the inner diameter side of the object to be measured 20, thereby inducing the connecting table 24 to stably move along the central axis of the space portion 21 of the object to be measured 20. .

또한, 상기 베이스블럭(22)을 원주방향으로 돌려가면서 반경방향으로 설치된 탐침체(23)를 원주방향으로 회전시켜가면서 동일한 깊이지점에서 여러방향의 내경차이를 측정할 수 있음으로써, 진원 또는 진구도를 판단할 수 있고, 가공산포를 측정할 수 있다.In addition, by rotating the base block 22 in the circumferential direction while rotating the probe 23 installed in the radial direction in the circumferential direction, it is possible to measure the difference in the inner diameter in several directions at the same depth point, the roundness or sphericity Can be determined, and the processing spread can be measured.
