Description
제 1 도는 본 고안의 설치상태도.1 is an installation state of the present invention.
제 2 도는 본 고안의 설치상태 단면도.2 is a cross-sectional view of the installation state of the present invention.
제 3 도는 본 고안의 핸들이 부착된 너트의 발췌사시도.3 is an exploded perspective view of a nut with a handle of the present invention.
본 고안은 본 출원인이 1976. 12. 23자 출원하여 등록을 받으바 있는 프로펠러 교정용 유압프레스(등록 번호 15942호)의 구조중에서 가압판을 회동식으로 개량한 프로펠러 교정용 유압프레스의 가압판에 관한 것이다.The present invention relates to a pressure plate of a propeller calibration hydraulic press for which the pressure plate is retrofitted in the structure of a propeller calibration hydraulic press (Registration No. 15942), which the applicant has filed and registered on December 23, 1976. .
종래의 프로펠러 교정용 유압프레스의 가압판은 프레스에 부동되게 고착되어 있기 때문에 교정이 필요한 부분이 프로펠러의 몸체 중심가까이에 있는 경우에는 가압판의 물리는 각도에 따라서는 프로펠러 날개의 가장자리가 프레스의 안쪽벽에 걸리기 때문에 가압판이 몸체중심까지 미치지 못해 교정이 불가능한 경우가 있었으며, 가압판의 물림각도를 조정 하기 위해서는 덩치가 크고 무거운 프레스 전체를 움직여야 하기 때문에 작업에 지장을 많이 주고 노력손실이 많았다.Since the pressure plate of the conventional propeller correction hydraulic press is fixedly fixed to the press, when the part to be corrected is near the center of the propeller body, the edge of the propeller blade is caught by the inner wall of the press depending on the biting angle of the pressure plate. Therefore, the plate could not be calibrated because the plate did not reach the center of the body, and in order to adjust the bite angle of the plate, a large and heavy press had to be moved.
본 고안은 종래 이러한 단점을 제거하고자 안출한 것으로서, 가압판의 저면에 축봉을 연설하여 프레스에 회동가능토록 유설하고 축봉하단에는 핸들이 유설된 너트를 나합하여 가압판의 방향을 임의로 회동시킬 수 있도록 함으로서 교정에 필요한 부분이 프로펠러의 몸체중심 가까이에 있는 경우라 할지라도 프로펠러 날개의 싸이드로 접근 가능토록 한 것이다.The present invention has been devised to eliminate such drawbacks, by speaking the shaft on the bottom of the pressure plate so that it can be rotated on the press, and the handle can be rotated at the bottom of the shaft so that the direction of the pressure plate can be arbitrarily rotated. Even if the part needed for calibration is close to the propeller body center, it is still accessible by the propeller blade side.
이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings as follows.
즉 가압판(1)의 하부에 나사부(2')를 형성한 축봉(2)을 입설하여 공지의 유압프레스(5)에 회동토록 유삽하고 축봉하단의 나사부(2')에는 핸들(4)을 유설한 너트(3)를 나합하여서 된 것이다.That is, the shaft bar 2 having the threaded portion 2 'formed on the lower side of the pressure plate 1 is inserted into the hydraulic press 5 so as to be rotated, and the handle 4 is attached to the threaded portion 2' at the lower end of the shafted rod. It was made by joining the loose nut 3 together.
이와같이 구성된 본 고안은 프로펠러의 날개를 교정할때 가끔 날개의 안쪽 즉, 몸체중심에 가까운 곳을 교정한 필요성이 발생되는데 종래에는 가압판(1)이 회동불가능하도록 프레스에 고정되어 있기 때문에 경우에 따라서는 프레스(5)의 안쪽벽이 날개 가장자리에 걸려 가압판(1)이 교정을 필요로 하는 부분까지 미치지 못해 교정이 불가능하였으나, 본 고안은 유압프레스(5)를 프로펠러의 날개 싸이드로 접근시키고 가압판(1)의 방향을 임의로 적당하게 조정한뒤 핸들(4)을 돌려 너트(3)로 조인다음 교정을 용이하게 할 수 있으며, 종래에는 가압판의 방향을 변경하려면 유압프레스 전체를 움직여야 하는 까닭에 힘들고 미세한 조정이 어려웠으나, 본 고안은 가압판(1)만을 회동시켜 각도를 조정할 수 있기 때문에 힘이 적게 들고 가압판(1)을 미세한 범위까지 정확하게 조정가능토록 한 것등의 특징을 지닌 것이다.The present invention configured as described above sometimes needs to correct the inner side of the wing, that is, near the center of the body when the wing of the propeller is calibrated. However, in some cases, the press plate 1 is fixed to the press so that it cannot be rotated. Although the inner wall of the press 5 was caught by the edge of the wing and the pressure plate 1 did not reach the portion requiring correction, the correction was impossible. However, the present invention approached the hydraulic press 5 with the wing side of the propeller and the pressure plate 1 ) Can be adjusted arbitrarily and appropriately, then the handle (4) can be tightened with the nut (3) to facilitate calibration.In the past, it is difficult to make fine adjustments because the entire hydraulic press must be moved to change the direction of the pressure plate. Although it was difficult, the present invention can adjust the angle by rotating only the pressure plate (1), so the force is less and the pressure plate (1) is finer range? It with the characteristics such that the ever be exactly adjusted.
