본 발명은 평면 및 각도를 가진 부품이나 기계장치들의 마모상태 혹은 진직도를 용이하게 측정하여 그 사용상태를 쉽게 판단할 수 있도록 한 각도 및 평면 진직도 측정장치에 관한 것이다.The present invention relates to an angle and plane straightness measuring device that can easily measure the wear state or the straightness of the parts or machinery having a plane and an angle to easily determine the state of use.

통상, 제철소의 압연공정은 롤 사이에 갭을 설정하고 그 사이로 소재를 통과시켜 소정 두께를 가진 압연제품을 생산하는 공정으로서 갭 설정 및 유지가 매우 중요한 요소중의 하나이다.In general, the rolling process of an ironworks is a process of setting a gap between rolls and passing a raw material therebetween to produce a rolled product having a predetermined thickness, which is one of very important factors.

특히, 압연력을 받는 소재의 평면마모 상태는 압연중 발생되는 통판 스트립의 축방향 쏠림이나 두께 편차, 꼬임, 판파단 등을 발생시키므로 그 마모상태를 측정하는 것은 매우 중요하다.In particular, the planar wear state of the material subjected to the rolling force causes axial pull, thickness variation, twisting, sheet breakage, etc. of the sheet strip generated during rolling, and therefore, it is very important to measure the wear state.

예컨대, 제철소의 압연공정중 압연력을 받는 부품의 일부를 도시한 도 1에 따르면, 백업롤(30)의 쵸크(32) 상부측에서는 하드라이너(34)의 상측이 집중적으로 압력을 받게 되며, 쵸크(32)의 하부측에서는 로크바(36) 부분에 집중적인 압연하중이 가해지게 된다.For example, according to FIG. 1, which shows a part of a part subjected to rolling force during a rolling process of a steel mill, the upper side of the hard liner 34 is concentrated at the upper side of the choke 32 of the backup roll 30, and the choke At the lower side of 32, a concentrated rolling load is applied to the lock bar 36 portion.

따라서, 상기 부분들의 진직도와 마모량에 따라 압연시 압연롤(30)의 진동에 커다란 영향을 미치게 되므로 이러한 부분들은 수시로 측정되어야 하며 확인이 요구된다.Therefore, since the parts have a great influence on the vibration of the rolling rolls 30 during rolling depending on the straightness and the amount of wear of these parts, these parts must be measured from time to time and confirmation is required.

종래에는 H형 평형자에 각도와 좌우치수를 측정할 수 있는 측정자가 제안되어 사용되었으나 이는 특정 부분의 마모량과 마모각만을 계측할 수 있도록 특수설계된 것이어서 전체적인 진직도 측정은 불가능하였고 또한 몇군데만을 샘플링하여 측정한 후 평균값을 산출하였으므로 전체적인 비틀림이나 마모도는 전혀 측정할 수 없었다.Conventionally, an H-type balancer has been proposed and used to measure angles and left and right dimensions, but it is specially designed to measure only the amount of wear and the wear angle of a specific part, so it is impossible to measure the overall straightness. After the measurement, the average value was calculated, so that the overall torsion and wear could not be measured at all.

본 발명은 상술한 바와 같은 종래 기술이 갖는 제반 문제점을 감안하여 이를 해결하고자 창출한 것으로, 정밀한 수평슬라이드와 수직슬라이드 및 각도조절기들이 한 몸체에 구비되고 조합되어 압연공정에 사용되는 쵸크와 압연력을 많이 받는 해당 부품들의 평면 및 각도의 진직도를 주기적으로 용이하게 점검할 수 있도록 한 각도 및 평면 진직도 측정장치를 제공함에 그 목적이 있다.The present invention has been made in view of the above-described problems of the prior art, and has been created to solve this problem. The precision horizontal slide, vertical slide and angle adjusters are provided in one body and combined to use the choke and rolling force used in the rolling process. An object of the present invention is to provide an angle and planar straightness measuring device that can easily check the plane and angle straightness of the corresponding parts that are frequently received.

상기 수평빔(110)에는 이를 따라 활주가능한 수평슬라이더(120)가 삽입되는 바, 이를 위해 상기 수평슬라이더(120)의 결합면에는 '⊃'형상의 고정홈(122)이 형성된다.A horizontal slider 120 that is slidable is inserted into the horizontal beam 110. For this purpose, a fixing groove 122 having a '⊃' shape is formed in a coupling surface of the horizontal slider 120.

수평슬라이더(120)의 배면에는 사각판상의 측정프레임(130)이 고정되고, 상기 측정프레임(130)상에는 고정프레임(140)이 결합된다.The rear surface of the horizontal slider 120 is fixed to the measurement frame 130 of the rectangular plate, the fixed frame 140 is coupled to the measurement frame 130.

상기 고정프레임(140)의 상하단에는 'U'형상의 작동홈(142)이 각각 형성되며, 상기 작동홈(142)중 하단측에는 측정아암(144)이 회전가능하게 힌지결합되고 상단측에는 각도조절아암(146)이 회전가능하게 힌지결합된다.The upper and lower ends of the fixed frame 140, 'U' shaped working grooves 142 are formed, respectively, the measuring arm 144 is hinged rotatably on the lower side of the operating groove 142 and the angle adjusting arm on the upper side 146 is rotatably hinged.

각도조절아암(146)에는 스핀들(152)이 회전가능하게 결합고정되고, 상기 스핀들(152)에는 각도조절기(150)가 연결된다.The spindle 152 is rotatably coupled to the angle adjusting arm 146, and the angle adjuster 150 is connected to the spindle 152.

상기 각도조절기(150)는 마이크로미터와 같은 것이 바람직하다.The angle adjuster 150 is preferably the same as the micrometer.

측정아암(144)의 상단 일측면에는 상기 스핀들(152)이 연결 고정된다.The spindle 152 is fixedly connected to one side of the upper end of the measuring arm 144.

또한, 상기 측정아암(144)의 타측면에는 수직방향으로 긴 수직빔(160)이 고정되고, 상기 수직빔(160)에는 이를 따라 승하강가능한 수직슬라이더(162)가 상기 수평슬라이더(120)와 동일한 방식으로 결합된다.In addition, a vertical beam 160 long in the vertical direction is fixed to the other side of the measuring arm 144, and the vertical beam 160 which can be moved up and down along the vertical beam 160 has the horizontal slider 120 and Combined in the same way.

수직슬라이더(162)의 배면에는 횡방향으로 고정바(164)가 고정되며, 상기 고정바(164)의 일측단부에는 고정볼트(172)에 의해 다이얼게이지(170)가 고정설치된 다.The fixing bar 164 is fixed to the rear surface of the vertical slider 162, and the dial gauge 170 is fixed to one side end of the fixing bar 164 by the fixing bolt 172.

아울러, 상기 베이스프레임(100)의 일측면에는 이동의 용이성을 확보하기 위한 한쌍의 핸들(180)이 고정되며, 베이스프레임(100)의 밑면에는 장착시 안착성 및 각도의 정도 조절용 세트볼트(190)가 구비된다.In addition, a pair of handles 180 are fixed to one side of the base frame 100 to secure the ease of movement, and a set bolt 190 for adjusting the degree of seating and angle at the bottom of the base frame 100 is mounted. ) Is provided.

이러한 구성으로 이루어진 본 발명은 다음과 같은 작동관계를 갖는다.The present invention made up of such a configuration has the following operational relationship.

도 2 내지 도 4를 참조하면, 쵸크(32)의 상부 평면인 하드라이너(34)의 마모상태를 측정하고자 할 경우에 작업자는 본 발명 장치인 베이스프레임(100)의 핸들(180)을 잡고 쵸크(32)의 상부로 이동하여 측정개소에 안착시킨 후 밀고 당김으로써 간단히 그 부분의 진직도나 각도 등을 용이하게 측정할 수 있게 된다.2 to 4, when the wear state of the hardliner 34, which is the upper plane of the choke 32, is to be measured, the operator grasps the handle 180 of the base frame 100, which is the device of the present invention, and chokes. By moving to the upper part of (32) and seating at the measuring location, pushing and pulling, the straightness and angle of the part can be easily measured.

즉, 상기 베이스프레임(100)을 측정개소에 안착시킨 후 평면의 진직도를 측정하고자 할 경우에는 각도조절기(150)를 영점조정하게 되면 스핀들(152)이 회전하면서 각도조절기(150) 내부로 인입되어 측정아암(144)이 수직상태로 입설되게 된다.That is, when the base frame 100 is to be seated at the measurement location and the straightness of the plane is to be measured, when the angle adjuster 150 is zeroed, the spindle 152 rotates and the lead is inserted into the angle adjuster 150. As a result, the measuring arm 144 is entered in a vertical state.

이 상태에서, 다이얼게이지(170)를 고정하고 있는 고정볼트(172)를 약간 풀어 다이얼게이지(170)의 측정부가 측정면에 수직이 되도록 하여 유동되지 않도록 견고히 고정한다.In this state, the fixing bolt 172 holding the dial gauge 170 is slightly loosened so that the measurement part of the dial gauge 170 is perpendicular to the measurement surface to fix it firmly so as not to flow.

세팅이 완료되면 다이얼게이지(170)의 눈금을 확인하면서 수평슬라이더(120)를 서서히 측정개소를 따라 이동시키면서 평면의 진직도를 측정하게 된다.When the setting is completed, the straightness of the plane is measured while gradually moving the horizontal slider 120 along the measurement location while checking the scale of the dial gauge 170.

아울러, 밑면을 기준으로 하는 각도를 가진 측면의 진직성을 측정하고자 할 경우에는 측정개소에 해당하는 각도로 다이얼게이지(170)를 조정한 후 상술한 바와 같은 측정작업을 수행하면 된다.In addition, if you want to measure the straightness of the side having an angle with respect to the base surface to adjust the dial gauge 170 at an angle corresponding to the measuring location and then perform the measurement as described above.

한편, 각도의 정도를 측정하고자 할 경우에는 측정개소에 해당하는 각도로 각도조절기(150)를 돌려 조정한 후 다이얼게이지(170)는 측정면에 대하여 수직을 유지토록 한 상태에서 베이스프레임(100)을 이동시키게 되면 각도의 오차나 편차를 용이하게 측정 대비할 수 있게 된다.On the other hand, if you want to measure the degree of the angle after adjusting the angle adjuster 150 by turning the angle adjuster 150 to the angle corresponding to the measuring position base frame 100 in a state to maintain the perpendicular to the measurement surface By moving, it is possible to easily contrast the measurement of errors or deviations in the angle.

이상에서 상세히 설명한 바와 같이, 본 발명은 평면 및 각도가 부여된 측정개소의 마모상태를 주기적으로 용이하게 점검할 수 있어 정비의 품질을 높일 수 있다.As described in detail above, the present invention can easily check the wear state of the measuring point given the plane and angle periodically and can improve the quality of maintenance.
