Abstract

PURPOSE: A turnbuckle having a load cell is provided to mount a mounting object to a specific site with a circular scale detecting plate and scale installed to a tip of a gap adjusting screw. CONSTITUTION: A gap adjusting screw(3,3') forming a ring(6,6') is assembled to a clamping nut(2,2') toward right and left directions. A circular scale indicating plate(4,4') is formed to an inner tip of the gap adjusting screw. Scale(5,5') is formed to a side of the clamping nut to indicate a gap. A tubular center portion(7) is formed to a middle portion of the clamping nut. A load cell(9) is composed of a strain gauge by processing an installing portion(8) from an upper side forming scale. The load cell is mounted to a turnbuckle(1). Therefore, a mounting object is mounted to a precise site by controlling a precise mounting site of the gap adjusting screw. Displacement of the gap adjusting screw and load on the clamping nut are measured by installing the load cell to the installing portion.

It relates to a turnbuckle equipped with a load cell.

종래의 턴버클은 특허공개번호 제2001-55141호(2001. 7. 4. 공개)와 같이 턴버클 몸체의 한쪽에는 오른나사의 너트를 반대편에는 왼나사의 너트를 일직선상에 설치하고, 상기 너트에 나사를 길게 형성한 간격조절 나사를 각각 조립하여 결합할 때 턴버클의 몸체를 회전함에 따라 좌우의 부품은 상호 가까워 지거나 멀어지도록 하여 거리의 조정을 필요로 하는 경우에 사용된다.Conventional turnbuckles have a right screw nut on one side of the turnbuckle body and a left screw nut on the opposite side as shown in Patent Publication No. 2001-55141 (published on July 4, 2001). When assembling and combining the long-form spacing screws, the left and right parts are used to require distance adjustment by moving the body of the turnbuckle closer or farther apart.

그러나 이러한 종래의 턴버클은 단순히 하중을 지지하는 역할만 하였고 정밀한 장착이 요구되는 용도에서는 적용할 수 없으며, 얼마만큼의 하중이 작용하는 지를 측정할 수 없었다.However, such a conventional turnbuckle merely serves to support the load and cannot be applied in applications requiring precise mounting, and it is not possible to measure how much load is applied.

본 발명은 정밀한 장착이 요구되는 용도에 장착한 후 간격조절 나사를 회전시켜 눈금 표시판과 눈금의 변화를 통하여 장착물의 위치 변화를 정밀 측정할 수 있도록 하는 것이다.The present invention is to be able to precisely measure the change in the position of the mounting through the change of the scale display plate and the scale by rotating the gap adjusting screw after mounting in the use that requires precise mounting.

본 발명은 조임너트의 중앙에 형성되는 원통형의 중심부에 형성된 설치부에 로드셀을 설치하여 하중을 측정할 수 있도록 하는 것이다.The present invention is to be able to measure the load by installing a load cell in the installation portion formed in the center of the cylindrical form formed in the center of the tightening nut.

본 발명은 조임너트의 일측으로 눈금이 설치되며 내부 공간에서 선단에 상기 눈금을 지시하는 원형의 눈금 지시판을 설치하는 간격조절 나사와,The present invention is a scale is installed on one side of the tightening nut and the interval adjusting screw for installing a circular scale indicating plate to indicate the scale at the tip in the inner space,

상기 조임너트의 중앙에 원통형 중심부를 설치하여 스트레인 게이지로 이루어져 조임너트의 하중을 측정하는 로드셀이 설치됨을 특징으로 하는 것이다.It is characterized in that the load cell for measuring the load of the tightening nut is installed consisting of a strain gauge by installing a cylindrical center in the center of the tightening nut.

In using for use that wearing is required

조임너트(2, 2')의 외측에서 간격조절 나사(3, 3')를 조립하여 내부에 원형의 눈금 지시판(4, 4')이 위치하도록 한다.Assemble the space adjusting screws 3, 3 'on the outside of the tightening nuts 2, 2' so that the circular scale indicators 4, 4 'are positioned inside.

양측의 간격조절 나사(3, 3')를 선택적으로 회전시키면 눈금 표시판(4, 4')이 간격조절 나사(3, 3')와 함께 회전되면서 직선이동 되므로 눈금(5, 5')을 통하여 간격조절 나사(3, 3')의 변위를 정확하게 확인할 수 있으므로 장착위치를 정밀하게 조정하면서 정확한 위치에 설치할 수 있는 것이다.By selectively rotating the gap adjusting screws (3, 3 ') on both sides, the scale display plates (4, 4') are rotated together with the gap adjusting screws (3, 3 '). Since the displacement of the space adjusting screws (3, 3 ') can be checked accurately, the mounting position can be precisely adjusted and installed at the correct position.

따라서 턴버클(1)을 이용하여 내통(11)을 정밀한 위치에 장착할 수 있는 것이다.Therefore, the inner cylinder 11 can be mounted in a precise position using the turnbuckle 1.

또한 원통형 중심부(7)의 설치부(8)에 설치된 로드셀(9)은 1개의 스트레인 게이지로 구성되어서 조임너트(2, 2')에 작용하는 하중을 확인할 수 있는 것으로 로드셀(9)과 응력 표시기(10)를 선으로 연결시키면 로드셀(9)에서 아날로그 신호가 출력되어 응력 표시기(12)에 전달되므로 표시창(13)을 통하여 디지털로 조임너트(2, 2')에 작용하는 하중을 확인할 수 있는 것이다.In addition, the load cell 9 installed in the mounting portion 8 of the cylindrical central portion 7 is composed of one strain gage so that the load acting on the tightening nuts 2 and 2 'can be checked. When 10 is connected by a line, an analog signal is output from the load cell 9 and transmitted to the stress indicator 12, so that the load acting on the tightening nuts 2 and 2 ′ digitally can be checked through the display window 13. will be.

본 발명은 간격조절 나사의 선단에 설치된 원형의 눈금 지시판과 눈금을 통하여 간격조절 나사의 정밀한 장착위치를 제어할 수 있으므로 간편하게 장착물을 정확한 위치에 장착할 수 있는 것이다.The present invention can control the precise mounting position of the spacing adjusting screw through a circular scale indicator plate and scale installed on the tip of the spacing adjusting screw can be easily mounted in the correct position.

본 발명은 원통형 중심부의 설치부에 로드셀을 설치하여 간격조절 나사의 변위와 조임너트에 작용하는 하중을 측정할 수 있는 것이다.The present invention is to install a load cell in the installation portion of the cylindrical center can measure the displacement of the gap adjusting screw and the load acting on the tightening nut.
