Description

직각도 검사 시스템{Squreness Inspection System}Squareness Inspection System {Squreness Inspection System}

본 발명은 직각도 정밀측정 검사시스템에 관한 것으로서, 보다 상세하게는 표준원통직각자와 배율증폭장치를 활용하여 기준면에 의한 수직면의 직각도 상태를 0.001㎜까지 검사 측정 할 수 있도록 하는 정밀측정 시스템에 관한 것이다.The present invention relates to an orthogonal precision measurement inspection system, and more particularly, to a precision measurement system that can inspect and measure the perpendicularity state of a vertical plane by a reference plane to 0.001 mm by using a standard cylindrical rectangular angle and a magnification amplifier. It is about.

일반적으로 직각도 검사는 고급연구소의 고급형의 직각검사 장비로는 스퀘어마스타가 있다. 그러나 이러한 고급장비를 생산현장에서 작업자가 일상적으로 사용할수 없는 것으로 인식되어있고, 손쉬운 방법으로는 직각자(1)를 활용하여서 피가공물(2)의 수직면에 접촉시키면서 육안으로 반대편의 빛의통과량의 정도를 인식하여 작업자의 두뇌내에서 추상적으로 임의적으로 직각도의값을 결정하게되는 현상이 보편화된 현실이다. 그예로써 도(2)에서와같이 직각자의 정점(4)을 기준하였을경우에 직각자 높이 끝부분에 (+)(-)의 부호와같 되는 것이 논리적 직각상태인데도 직각자로 직각을 비교 측정하는 작업자는 직각자정밀도 신뢰도를 100%라고 단정지어 결정하면 직각자의 잘못된 오차는 피측정물의 직각정밀도에 반영되어 신뢰 할 수 없는 문제점이 있었다.In general, the squareness test is a square master of the high-quality square-angle inspection equipment of the advanced research institute. However, it is recognized that such advanced equipment cannot be used routinely by workers in the production site, and an easy way is to use the right angler (1) to contact the vertical surface of the workpiece (2) with the naked eye and through light passing through the opposite side. The phenomenon that determines the degree of squareness randomly in the brain of the worker by recognizing the degree of is the general reality. For example, the operator who compares the right angle with the right angle even though it is logical right angle when the reference to the vertex 4 of the right angle as shown in Fig. (2) refers to the sign of (+) (-) at the end of the right angle. If we determine that the squareness accuracy is 100%, the error of the squareness is reflected in the squareness accuracy of the measured object, which is unreliable.

본 발명은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 생산가공현장과 기술교육 실습장에서 공히 직각도를 사실에 입각하여 정확하고 민첩하게 검사측정하고, 측정된 지시값을 숫자로 지시하여 정확하고 신뢰도 높은 직각도검사 측정 시스템을 제공하는 것을 목적으로 한다.The present invention has been devised to solve the above-mentioned shortcomings, and at the production processing site and the technical training workshop, the squareness is accurately and agilely measured and measured by the facts, and the measured indications are indicated by numbers to be accurate.

본 발명은 금속 및 비금속의 가공·조립 직각도 정밀측정검사 방법에 있어서,The present invention provides a method for precisely inspecting processing and assembling squareness of metals and nonmetals,

측정자(봉)와 배율증폭용 배율축을 3단계 직렬 조립시켜 (1:1)과 (2:1)과 (5:1)과 (10:1)로 배율하는 단계, 원통직각자를 표준기구로 하여 영점 정지부를 고정시키고 측정자 위치를 교정 고정하는 단계, 다이알게-지 고정형 배율증폭 장치부와 측정자 상·하 이동 슬라이더를 고정 결합할 수 있는 원통형 슬리브를 장착하는 단계, 다이알게-지와 배율증폭장치부가 측정자 상·하 이동을 용이하게 하기위하여 표준지지 기둥에 래크기어를 장착하고, 측정자 상·하 이동 슬라이더 몸체에 피니언 기어축을 조립장착하는 단계, 이동높이를 빨리 인식할수 있게끔 눈금자를 기둥에 장착하는 단계를 갖는다.Assembling the measuring device (rod) and the magnification axis for magnification in three stages in series to magnify it with (1: 1), (2: 1), (5: 1) and (10: 1). Fixing the zero stop and calibrating the position of the meter; mounting a cylindrical sleeve capable of fixedly combining the dial-edge fixed magnification unit and the meter up / down slider; dial-edge and magnification Attaching rack gear to standard support column to facilitate additional measuring device up and down movement, and assembling and mounting pinion gear shaft to measuring body up and down slider body. It has a step.

도 5는 측정자(11)가 감지한 측정값을 2.5:1 배율축(21)을 밀면 측정자(11)의 후미라운드 형상부가 2.5:1 배율축(21) 경사면에 미끄러지면서 후진을 한다.FIG. 5 shows that when the measurement value detected by the measurer 11 is pushed on the 2.5: 1 magnification axis 21, the trailing round shape portion of the measurer 11 slides on the slope of the 2.5: 1 magnification axis 21.

이때에 서로작용거리는 2.5:1이 성립된다. 그 공식이(tan26°48′5.07″=0.4)=1≒0.4=2.5이다. 그리고 2.5:1 배율축(21)이 후진상승하면 2:1 배율축(22)의 경사면을 밀게 된다. 이 경우에도 앞 공정의 2.5:1배율축(21)이 1이라는거리가 작용할때에 2:1 배율축(22)은 2의 값만큼 이동하게 된다. 그 공식은(tan26°33′54.18″=0.5)=1≒0.5=2가된다. 그리고 2:1 배율축(22)이 2:1 배율축(23)을 후진하여 밀면 역시 위공식이 성립되므로 배율값을 정리하면(2.5×2×2=10)이라는 배율 총값이 성립되므로 10배율증폭장치가 구성되게 된다. 그후 다이알게-지(14)를 2:1배율축(23)의 후미평면부에 닿도록 밀착조립시키고 고정시킨다.At this time, the interaction distance is 2.5: 1. The formula is (tan26 ° 48′5.07 ″ = 0.4) = 1 ≒ 0.4 = 2.5. Then, when the 2.5: 1 magnification axis 21 reverses upward, the inclined surface of the 2: 1 magnification axis 22 is pushed. Even in this case, when the distance of 2.5: 1 magnification axis 21 of the preceding process is 1, the 2: 1 magnification axis 22 is moved by a value of 2. The formula is (tan 26 ° 33 '54.18 "= 0.5) = 1 0.5. And if the 2: 1 magnification axis 22 is pushed backward by 2: 1 magnification axis 23, the porosity is also established. The amplification device is configured. The dialge-paper 14 is then tightly assembled and secured to contact the trailing plane of the 2: 1 magnification shaft 23.

그리고 측정자 지지슬리브(24)를 상,하 이동 슬라이더(9)에 삽입시켜서 고정시킨다음 도4에서와 같이 피측정위치를 상,하 이동기어 회전축(10)을 돌려서 직각도 측정요구 위치가 되게한 후 정지나사(17)로 견고하게 고정시키고 영점정지부(12)를 적당한 위치에 고정시킨 후 원통직각자(6)를 영점정지부(12)에 닿을때까지 조심히 밀착시키면 측정자(11)는 후진하여 다이알게-지(14)의 지시침이 움직인다.Then, the measuring support sleeve 24 is inserted and fixed to the up / down moving slider 9, and then, as shown in FIG. 4, the up / down moving gear rotation shaft 10 is turned to be the right angle measurement request position as shown in FIG. After fixing firmly with the stop screw (17) and the zero stop part (12) at a proper position, and then closely contact the cylindrical square (6) until it reaches the zero stop part (12) the measurer (11) The indicator hand of the dialge-ji 14 is moved.

이때에 다이알게-지(14)의 문자판을 회전시켜서 0점에 일치시키고 도4와 같이 측정 작업을 수행하게 되는 것이다. 이상과 같은 구성조건이 완성된 것으로 직각도 검사측정을 하게 되면 사실적 측정 감지량이 0.01㎜라고하면 다이알게-지(14)의 지시침은 10개의 눈금위치에 정지해 있게 된다. 이 경우에는 0.1㎜라고 인식해서는 아니된다. 그 사유는 0.01㎜를 10등분했다고 보아야 옳은 방법이 된다.At this time, the dial of the dialge-paper 14 is rotated to match the zero point and the measurement operation is performed as shown in FIG. When the squareness inspection measurement is completed as described above, if the actual measurement detection amount is 0.01 mm, the indicator needle of the dialge paper 14 stops at ten graduation positions. In this case, 0.1 mm is not to be recognized. The reason is that it is correct to divide the 0.01mm into 10 pieces.

이렇게 되어 눈금을 인지하기가 매우 용이하게 되고 아나로-그식의 눈금이나, 디지털방식의 숫자표시가 되면 직각도의 측정값을 객관적으로 인식 관리할 수 있게 되므로 작업시간 단축과 측정검사 시간을 단축할 수 있을 것이다.This makes it very easy to recognize the scale, and when an analog-style scale or digital number display is used, objective measurement of the squareness can be objectively recognized and managed. Could be.
