Description

내경 스플라인(Spline)의 오버 핀경 측정용 지그Jig for over pin diameter measurement of spline

본 고안은 스플라인(Spline) 내경 측정구에 관한 것으로 특히, 알터네이터의 펌프 로터 스플라인부 내경(Over Pin 徑) 측정에 적합하도록 한 것이다.The present invention relates to a spline inner diameter measuring sphere, and in particular, to be suitable for measuring the diameter of the alternator pump rotor spline (Over Pin 徑).

종래에는 도 1에 나타낸 바와 같이 내경 스플라인(1)부의 오버 핀 경(Over Pin 徑) 측정을 위해 먼저, 스플라인(1)의 양쪽 내경부(10)(10')에 두 개의 핀(2,2')(Pin)이 마주 향하도록 대향되게 배치한 다음, 상기 내경부(10)(10')에 끼워지는 양쪽핀(2,2')간의 거리(ℓ)를 내경 마이크로미터(Micrometer)를 이용하여 측정하고 있다.Conventionally, as shown in FIG. 1, two pins 2 and 2 are formed at both inner diameter portions 10 and 10 ′ of the spline 1 to measure the over pin diameter of the inner diameter spline 1. ') (Pin) is disposed to face each other, and then the distance (l) between the two pins (2, 2') fitted to the inner diameter portion (10, 10 ') using an inner diameter micrometer (Micrometer) Is measured.

이처럼 종래에는 스플라인(1)의 내경 측정을 위해 스플라인(1)의 홈 부분(내경부)에 별도의 핀(2,2')을 끼우고 빼는 불편함이 있고, 내경 스플라인(1)의 홈에 끼워지는 핀(2,2')이 고정되도록 별도의 고정장치 즉 자석을 이용하여 고정시켜야만 하는 등의 번거러움이 있어 측정시간이 많이 소요되는 단점이 있다.As such, there is a conventional inconvenience of inserting and removing separate pins 2 and 2 'in the groove portion (inner diameter portion) of the spline 1 to measure the inner diameter of the spline 1, and in the groove of the inner diameter spline 1 Since pins 2 and 2 'to be fitted are fixed by using a separate fixing device, that is, a magnet, there is a disadvantage in that a lot of measurement time is required.

스플라인(1)의 홈에 끼워지는 양쪽 핀(2)과 핀(2')사이를 측정하는 마이크로미터의 측정 방향에 따라 오차가 발생되어 신뢰도가 낮을 뿐만 아니라, 정밀도가 떨어지는 등의 문제점을 안고 있었다.An error occurred depending on the measurement direction of the micrometer measuring between both the pins 2 and the pins 2 'fitted into the grooves of the spline 1, resulting in low reliability and poor accuracy. .

본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여, 스플라인의 내경부에 측정기(지그)를 끼우고 빼는 것만으로 간편하면서도 신속하게 스플라인의 내경부를 측정할 수 있도록 된 내경 스플라인의 오버 핀경 측정용 지그를 제공함에 그 목적이 있는 것인 바, 이를 첨부된 예시 도면을 참고하여 보다 상세히 설명하면 다음과 같다.The present invention is to solve the conventional problems as described above, for measuring the over-pin diameter of the inner diameter spline to be able to measure the inner diameter of the spline simply and quickly simply by inserting and removing the measuring device (jig) in the inner diameter of the spline The purpose is to provide a jig, which will be described in more detail with reference to the accompanying example drawings as follows.

도 1은 종래 내경 스플라인의 오번 핀경을 측정하는 것을 나타낸 참고도,1 is a reference diagram showing the measurement of the wrong pin diameter of the conventional inner diameter spline,

도 2는 본 고안이 적용된 측정용 지그의 예시도,2 is an exemplary view of a measuring jig to which the present invention is applied,

3 : 지그 4 : 최대 허용공차3: Jig 4: Maximum Tolerance

5 : 최소 허용공차 30: 손잡이5: Minimum Tolerance 30: Handle

도 2 는 본 고안이 적용되는 내경 스플라인의 오버 핀경 측정용 지그의 예시도를 묘사하고 있는 것으로, 본 고안은 내경 스플라인에 형성되는 오버 핀경을 측정하는 측정구를 형성함에 있어서, 중앙에 손잡이(30)가 구비되는 지그(3)의 양단부에 서로 대향되게 배치되는 상·하핀(2,2')을 고정하되, 한쪽은 상· 하부에 고정되는 양쪽 핀(2,2')간의 거리가 내경 스플라인(1) 오버 핀경의 최대(Maximum) 허용공차부(4)를 이루게 하고, 그 반대쪽은 양쪽 핀(2,2')간의 거리가 내경스플라인(1) 오버 핀경의 최소(Minimum) 허용공차부(5)를 이루도록 구성되고 있는 것이다.Figure 2 depicts an exemplary view of the jig for measuring the over pin diameter of the inner diameter spline to which the present invention is applied, the present invention in forming a measuring sphere for measuring the over pin diameter formed on the inner diameter spline, the handle 30 in the center ) Is fixed to the upper and lower pins (2, 2 ') disposed opposite to each other at both ends of the jig (3) provided with one side, but the distance between the two pins (2, 2') fixed to the upper and lower sides is the inner diameter spline (1) The maximum tolerance of the over pin diameter is achieved (4), and on the opposite side, the distance between the two pins (2, 2 ') is the inner diameter spline (1) The minimum tolerance of the over pin diameter ( 5) It is configured to achieve.

이와 같이 본 고안은 내경 스플라인의 오버 핀경을 검사 측정하고자 하는 측정물의 기준이 되는 최대 허용치(Maximum)와 최소 허용치(Minimum)를 지그(3)의 양쪽에 미리 세팅시킴으로서, 스플라인의 오버 핀경을 측정하고자 할 경우에는 먼저, 지그(3)의 한쪽에 형성시킨 최소 허용공차부(5)쪽을 스플라인의 내경부에 형성되는 오버 핀경에 끼워지도록 밀어 넣어 스플라인 내경부의 최소 허용치를 검사하고, 다시 지그(3)의 최대 허용공차부(4)쪽을 스플라인의 오버 핀경에 밀어넣으므로서 스플라인의 내경에 가공되는 오버 핀경의 허용치를 측정, 검사를 할 수 있게 된다.In this way, the present invention is to measure the over pin diameter of the spline by setting the maximum and minimum allowable values on both sides of the jig 3 in advance, which are the standards of the workpiece to be measured and measured. In order to do this, first, the minimum allowable tolerance portion 5 formed on one side of the jig 3 is pushed so as to fit the over pin diameter formed on the inner diameter portion of the spline, and the minimum allowable value of the internal diameter of the spline is examined. By pushing the side of the maximum allowable part (4) of 3) into the over pin diameter of the spline, the allowable value of the over pin diameter processed to the inner diameter of the spline can be measured and inspected.

이상에서 설명한 바와 같이 본 고안 지그를 스플라인의 내경부로 끼워지도록 밀어 넣는 것만으로 스플라인에 가공되는 오버 핀경의 검사를 끝마칠 수 있어 그 작업이 간편하고 손쉽게 이루어지는 이점이 있게 된다.As described above, by simply pushing the jig of the present invention to be fitted into the inner diameter of the spline, the inspection of the over pin diameter processed on the spline can be completed, so that the operation is simple and easy.

따라서 종래와 같이 내경 스플라인의 오버 핀경을 측정하기 위해 오버 핀경에 핀을 끼운 다음, 상기 핀이 고정되도록 자석을 이용하여 핀을 고정시키는 번거러움과 불편함 등이 없게 되어 작업시간이 대폭 절감되어짐은 물론 측정 오류등을 방지할 수 있다는 장점을 지니는 등의 효과가 있게 된다.Therefore, after inserting the pin to the over pin diameter to measure the over pin diameter of the inner diameter spline as in the prior art, there is no hassle and inconvenience of fixing the pin using a magnet so that the pin is fixed. This has the advantage of preventing measurement errors and the like.
