본 고안은 정밀 측정용 잭(Jack)에 관한 것으로서 특히, 마이크로 미터(Micro-Meter) 헤드부의 눈금 및 작동원리를 적용하여 높낮이의 미세조정 및 그 이동량의 확인이 가능하도록 한 구조의 정밀 측정용 잭을 제공하려는 것이다.The present invention relates to a jack for precision measurement, and particularly, a jack for precision measurement of a structure that enables fine adjustment of the height and confirmation of its movement amount by applying the scale and operating principle of the micro-meter head part. Is to provide.
일반적으로 제품의 정밀측정시 정반위에 인디게이터(Indi-cator)가 부착된 높이 게이지로써 평면도, 동심도, 평행도, 진위치도 등을 측정하게 되는데, 이때 제품의 저면에는 정반과의 사이에 잭(Jack)으로 3점 지지하여 제품의 높낮이 및 평면도를 조정한 후 측정하게 된다.In general, the precision gauge of the product is a height gauge with an indicator (Indi-cator) attached to the surface to measure the flatness, concentricity, parallelism, true position, etc. At this time, the bottom of the product between the jack and the surface plate It is measured after adjusting the height and flatness of the product by supporting 3 points by.
그러나 종래의 잭은 제4도에 도시된 바와같이, 원추형 받침대(51)와 두부에 원추형 지지부(52)가 형성된 스크류(53)를 결합하여 사용되어 왔으나 이 구조는 스크류(53)의 나사산 피치가 크고 눈금이 없기 때문에, 미세조정이 불가능하고 그 이동량의 확인이 불가능하여 조정시간이 많이 소비되고 정확한 측정이 어려운 문제점을 내재하고 있었다.However, the conventional jack has been used to combine the conical pedestal 51 and the screw 53 with the conical support 52 formed on the head, as shown in Figure 4, but this structure has a thread pitch of the screw 53 Because of its large scale and lack of scale, fine adjustment is impossible and its movement amount cannot be confirmed, which causes a lot of adjustment time and accurate measurement.
따라서 본 고안은 상기의 종래 제반 문제점을 해결하기 위해 안출된 것으로서, 그 특징은 기존의 잭 스크류부에 마이크로 미터의 눈금 및 작동 원리를 적용하여 높낮이의 미세조정 및 그 이동량을 확인할 수 있도록 한 구조를 제공하려는데 그 목적이 있는 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve the above-mentioned conventional problems, and its feature is a structure that enables to check the fine adjustment of the height and the movement amount by applying the micrometer scale and the operating principle to the existing jack screw part. The purpose of the present invention will be described in detail with reference to the accompanying drawings as follows.
도시한 바와같이, 슬리이브(1)와 딤블(2)이 가는 나사로 결합되어지는 통상의 마이크로 미터의 헤드(3)에 있어서, 딤블(2)의 상부에는 원추형 측정물 지지부(4)와 손잡이(5)가 형성되고 하부에는 받침대(6)를 설치하여서 구성된 것이다.As shown, in the head 3 of a conventional micrometer, in which the sleeve 1 and the tumble 2 are joined by a thin screw, the conical workpiece support 4 and the handle ( 5) is formed and is formed by installing a pedestal (6) at the bottom.
미설명 7은 눈금, 8은 정반이다.Description 7 is a scale and 8 is a table.
이와같이 구성된 본 고안의 작동원리는 기존 마이크로 미터 헤드의 작동원리와 동일한 것으로서, 딤블(2)의 손잡이(5)를 좌우로 회전시켜서 높낮이를 조정을 하며 이에 새겨진 눈금(7)을 읽어 이동량을 확인하는 것이다.The operation principle of the present invention configured as described above is the same as the operation principle of the existing micrometer head, and adjusts the height by rotating the handle 5 of the dumble 2 to the left and right to check the movement amount by reading the scale 7 engraved thereon. will be.
따라서 본 고안을 적용하여 정밀 측정을 하고자 할때에는 본 고안의 잭 3개를 정반(8)위에 각각 설치한 후 제품을 측정물 지지부(4)위에 올려놓고 각각의 잭 손잡이(5)를 좌우로 돌리면서 제품의 높낮이를 조정하며 이때 딤블(2)의 이동량을 알고자 할때에는 슬리이브(1)와 딤블(2)에 표시된 눈금(7)을 읽어 확인한다.Therefore, when you want to make a precise measurement by applying the present invention, after installing three jacks of the present invention on the surface plate (8) respectively, put the product on the workpiece support (4) and turn each jack handle (5) to the left and right The height of the product is adjusted. At this time, if you want to know the amount of movement of the tumble (2), check the scale (7) marked on the sleeve (1) and the tumble (2).
이상에서와 같이 본 고안에 의하면 종래의 잭 스크류에 마이크로 미터 헤드부의 눈금 및 작동원리를 적용함으로써, 높낮이의 미세조정 및 그 이동량의 확인이 가능하여 정밀 측정에 용이하게 사용할 수 있는 고안인 것이다.As described above, according to the present invention, by applying the scale and the operating principle of the micrometer head to the conventional jack screw, it is possible to make fine adjustment of the height and confirmation of the movement amount and to be easily used for precision measurement.
