Description

동흡진기 선별장치{DEVICE FOR CHOOSING DAMPER}Dynamic Reducer Separator {DEVICE FOR CHOOSING DAMPER}

본 발명은 측정장치에 관한 것으로, 더욱 상세하게는 동흡진기의 정확한 진동 주파수를 확인하여 양호품을 선별하기 위한 동흡진기 선별장치에 관한 것이다.The present invention relates to a measuring device, and more particularly to a copper reducer screening device for screening good products by checking the exact vibration frequency of the copper reducer.

일반적으로 지속적인 진동이 가해지는 차량 등에는 진동 저감을 위하여 질량과 고무로 합성된 동흡진기가 사용되며, 이 동흡지기는 차체와 이에 고정되는 피고정물 사이에 설치되어 진동을 흡수하게 된다.In general, a vibration reducer composed of mass and rubber is used to reduce vibration in a vehicle to which continuous vibration is applied, and the dynamic absorber is installed between the vehicle body and a fixed object fixed thereto to absorb vibration.

즉, 차량에 사용되는 각 부재는 고유의 진동수를 가지고 있는 데, 이 진동수가 엔진의 진동수와 일치하게 되면 진동과 소음이 유발된다. 따라서 동흡진기의 사용으로 진동과 소음을 방지할 수 있게 되는 것이다.That is, each member used in the vehicle has a unique frequency, and when the frequency matches the frequency of the engine, vibration and noise are caused. Therefore, it is possible to prevent vibration and noise by using a copper reducer.

그런데, 상기 동흡진기는 일정한 주파수에서만 작동하기 때문에 정확한 주파수에 튜닝되어 있지 않으면 오히려 역효과가 발생하여 진동과 소음을 증폭시키게 된다.However, since the copper reducer operates only at a constant frequency, if it is not tuned to the correct frequency, a reverse effect occurs rather than amplifying vibration and noise.

또한, 소음과 진동저감효과가 없는 부재를 장착하여 차량의 총무게만을 늘려 연비와 동력성능을 불리하게 하는 결과를 낳게 된다.In addition, by mounting a member having no noise and vibration reduction effect increases the total weight of the vehicle, resulting in disadvantages in fuel efficiency and power performance.

이와 같이 동흡진기는 매우 중요한 기능을 수행하므로 해당 주파수에 맞는 동흡진기를 차량에 장착해야 함은 두말할 필요도 없다 할 것이다.As such, the copper reducer performs a very important function, it is needless to say that the vehicle needs to be equipped with the corresponding copper reducer.

그러나 종래에는 동흡진기의 주파수 특성을 간편하게 측정할 수 있는 장치가 전무하여 제조업체에서 몇 개 단위로 샘플링하여 동흡진기를 검사하므로, 실제 차량에 장착되는 동흡진기는 품질 산포를 유발하는 문제점이 있다.However, in the related art, since there is no device capable of easily measuring the frequency characteristics of the copper reducer, the manufacturer inspects the copper reducer by sampling a few units, and thus, the dynamic reducer mounted on the actual vehicle causes quality distribution.

또한, 종래에는 동흡진기의 주파수 특성을 검사하기 위하여 많은 검사인원과 큰 규모의 검사장비가 필요하여 검사에 소요되는 비용이 높아지는 문제점이 있다.In addition, in the related art, a large number of inspectors and a large-scale inspection equipment are required to inspect the frequency characteristics of the copper reducer, thereby increasing the cost of inspection.

이에 본 발명은 상기와 같은 제반 문제점을 해결하기 위하여 안출된 것으로, 동흡진기의 질량 부분의 변위량을 간편하게 측정하여 주파수 특정별로 우량품과 불량품을 선별할 수 있도록 된 동흡진기 선별장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, and the object of the present invention is to provide a copper reducer screening device that can select the good and defective by frequency specific by simply measuring the displacement of the mass portion of the copper reducer have.

도 1은 본 발명에 따른 동흡진기 선별장치를 도시한 개략적인 사시도이다.1 is a schematic perspective view showing a copper reducer screening apparatus according to the present invention.

도 1은 본 발명에 따른 동흡진기 선별장치를 도시한 개략적인 사시도이다.1 is a schematic perspective view showing a copper reducer screening apparatus according to the present invention.

상기한 도면에 의하면, 본 발명은 검사가 진행될 동흡진기(50)가 놓여지는 진동 플레이트(10)와, 이 진동 플레이트(10) 하부에 설치되어 진동 플레이트(10)를 특정 주파수로 진동시키기 위한 가진기(11), 상기 진동 플레이트(10) 상부에 위치하여 동흡진기(50)의 변위를 계측하기 위한 계측기(20), 상기 진동 플레이트(10)로부터 낙하되는 동흡진기(50)가 수거되고 중간에 칸막이(31)가 설치되어 불량품과 양호품을 분리 수거할 수 있도록 된 수거함(30), 상기 각 수거함(30)이 놓여지고 동흡진기(50)의 계측결과에 따라 해당 수거함(30)을 진동 플레이트(10)의 동흡진기(50) 낙하위치로 이동시키기 위한 컨베이어(32)를 포함하여 이루어진다.According to the above-described drawings, the present invention provides a vibration plate 10 on which the dynamic reducer 50 to be inspected is placed, and a vibration plate 10 installed below the vibration plate 10 to vibrate the vibration plate 10 at a specific frequency. 11, a meter 20 for measuring the displacement of the copper reducer 50 positioned above the vibration plate 10, and a copper reducer 50 falling from the vibration plate 10 are collected and A partition 31 is installed so that the defective and good can be collected separately, the bin 30, each bin 30 is placed and according to the measurement result of the copper reducer 50, the bin 30 is vibrated plate Conveyor 32 for moving to the copper reducer 50 in the drop position of (10).

여기서 상기 진동 플레이트(10) 상에는 동흡진기(50) 계측시 동흡진기(50)를 고정시킬 수 있도록 전자석판(12)이 설치됨이 바람직하다.Here, the electromagnet plate 12 is preferably installed on the vibration plate 10 so as to fix the copper reducer 50 when the copper reducer 50 is measured.

또한, 상기 계측기(20)는 상기 진동 플레이트(10)에 놓여진 동흡진기(50)의 상부에 접하는 계측침(21)이 설치되고 이 계측침(21)의 상하 유동량을 측정하기 위한 다이얼 게이지(22)를 포함하여 구성된다.In addition, the measuring device 20 is provided with a measuring needle 21 in contact with the upper portion of the copper reducer 50 placed on the vibrating plate 10, and the dial gauge 22 for measuring the amount of vertical flow of the measuring needle 21. It is configured to include).

따라서 가진기(11)가 부여하는 특정 진동 주파수에 대해 동흡진기(50)의 변위량은 계측침(21)을 통해 다이얼 게이지(22)로 전달되어 변위량을 검출할 수 있게 되는 것이다.Therefore, the displacement amount of the copper reducer 50 is transmitted to the dial gauge 22 through the measuring needle 21 with respect to the specific vibration frequency imparted by the exciter 11 to detect the displacement amount.

한편, 본 실시예에 따르면 상기 동흡진기(50)를 진동 플레이트(10)로부터 수거함(30)으로 낙하시키기 위하여 별도의 낙하수단이 구비되는 데, 이를 위해 상기 낙하수단은 가진기(11) 상부에 수평방향으로 놓여지는 구동 실린더(40)와, 이 구동 실린더(40)의 피스톤 로드 선단에 설치되어 동흡진기(50)를 밀어내기 위한 밀판(41)으로 이루어진다.On the other hand, according to the present embodiment is provided with a separate drop means for dropping the copper reducer 50 from the vibrating plate 10 to the collection box 30, for this purpose, the drop means is provided on the top of the vibrator (11) It consists of a drive cylinder 40 placed in the horizontal direction, and a sealing plate 41 provided at the tip of the piston rod of the drive cylinder 40 to push the copper reducer 50.

따라서 구동 실린더(40)가 신장 작동되면 밀판(41)이 동흡진기(50)를 수거함(30)으로 밀어내게 되는 것이다.Therefore, when the driving cylinder 40 is extended, the plate 41 will push the copper reducer 50 to the collection box 30.

또한, 상기 수거함(30)은 도 1에 도시된 바와 같이 가진기(11) 측면에 설치된 컨베이어(32) 위에 설치되며 상부는 개방되어 있고, 중앙에는 칸막이(31)가 설치된 구조로 되어 있다.In addition, the collection box 30 is installed on the conveyor 32 installed on the side of the exciter 11, as shown in Figure 1, the upper portion is open, the partition 31 is installed in the center.

이하 본 발명의 작용에 대해 설명한다.Hereinafter will be described the operation of the present invention.

동흡진기(50)가 진동 플레이트(10) 상에 설치된 전자석판(12) 위에 놓여지면 전자석판(12)에 전원이 인가되어 전자석판(12)을 자석화시킴으로써 자력에 의해 동흡진기(50)가 전자석판(12)에 고정된다.When the copper reducer 50 is placed on the electromagnet plate 12 installed on the vibrating plate 10, power is applied to the electromagnet plate 12 to magnetize the electromagnet plate 12 to magnetize the copper reducer 50 by magnetic force. It is fixed to the electromagnet plate 12.

이 상태에서 다이얼 게이지(22)에 연결된 계측침(21)을 동흡진기(50) 상부에 접하도록 이동시키고 가진기(11)를 특정주파수에 맞춰 진동시킨다.In this state, the measuring needle 21 connected to the dial gauge 22 is moved to be in contact with the upper portion of the copper reducer 50 and the vibrator 11 is vibrated to a specific frequency.

상기 가진기(11)의 진동작용에 따라 진동 플레이트(10)가 진동되어전자석판(12)에 놓여진 동흡진기(50)에 특정 주파수의 진동을 가하게 된다.The vibration plate 10 is vibrated according to the vibration action of the exciter 11 to apply a vibration of a specific frequency to the copper reducer 50 placed on the electromagnet plate 12.

이에 동흡진기(50)는 동흡진기(50) 고유의 주파수 특성에 맞춰 진동을 흡수하게 되고 이러한 동흡진기(50)의 변위량은 계측침(21)을 통해 다이얼 게이지(22)에 수치로 나타난다.Accordingly, the copper reducer 50 absorbs the vibration according to the inherent frequency characteristic of the copper reducer 50, and the displacement amount of the copper reducer 50 is numerically displayed on the dial gauge 22 through the measuring needle 21.

예컨데, 상기 가진기(11)가 250헤르츠로 가진되면 정확히 튜닝된 동흡진기(50)의 경우 250헤르츠에서 동흡진기(50)의 질량부분 변위가 제일 높게 나타난다.For example, if the exciter 11 is excited at 250 hertz, the precisely tuned copper reducer 50 exhibits the highest displacement of the mass portion of the copper reducer 50 at 250 hertz.

즉, 정확하게 튜닝된 동흡진기(50)의 경우 변위값이 설정된 값보다 높게 나타나며 이는 검사되는 동흡진기(50)가 양호품임을 의미한다.That is, in the case of the accurately tuned dynamic reducer 50, the displacement value is higher than the set value, which means that the dynamic reducer 50 to be inspected is a good product.

반대로 동흡진기(50)가 불량품이라면 측정되는 변위량이 설정값보다 낮게 나오게 되며 따라서 본 장치는 검사되는 동흡진기(50)가 불량품임을 인식하게 된다.On the contrary, if the copper reducer 50 is defective, the measured displacement amount is lower than the set value, and thus, the apparatus recognizes that the inspected copper reducer 50 is defective.

검사를 마치게 되면 동흡진기(50)가 불량품인지 또는 양호품인지에 따라 수거함(30)에 분리 수거하게 된다.When the inspection is finished, the copper reducer 50 is separately collected in the collection box 30 according to whether the defective or good.

검사 결과치는 릴레이를 통해 컨베이어(32)로 인가되어 컨베이어(32)의 이동량을 제어하게 되고 컨베이어(32) 위에 놓여진 수거함(30)의 위치를 동흡진기(50) 낙하위치에 맞춰 조절하게 된다.The inspection result is applied to the conveyor 32 through a relay to control the moving amount of the conveyor 32 and to adjust the position of the collection box 30 placed on the conveyor 32 in accordance with the falling position of the copper reducer 50.

즉, 동흡진기(50)가 양호품인 경우에는 칸막이(31)에 의해 구분되는 수거함(30)의 양호품 수거부가 동흡진기(50) 낙하 위치로 이동하게 되고 이 상태에서 전자석판(12)의 전원을 차단하여 동흡진기(50)의 고정상태를 해제한다.That is, when the copper reducer 50 is a good product, the good collection part of the collection box 30 divided by the partition 31 is moved to the copper reducer 50 falling position, and the electromagnet 12 is in this state. Shut off the power to release the fixed state of the copper reducer (50).

그리고 구동 실린더(40)를 신장 작동시켜 구동 실린더(40)의 피스톤 로드 선단에 설치된 밀판(41)이 동흡진기(50)를 밀어 바로 밑에 위치한 수거함(30)의 양호품 수거부에 동흡진기(50)를 떨어뜨리게 되는 것이다.In addition, the driving cylinder 40 is extended and operated, and the plate 41 installed at the tip of the piston rod of the driving cylinder 40 pushes the copper reducer 50, and the copper reducer 50 is disposed on the good collection section of the collection box 30 located directly below. ) Will be dropped.

물론, 불량품으로 결과가 나온 경우에는 상기 컨베이어(32)는 수거함(30)의 불량품 수거부를 동흡진기(50) 낙하위치로 이동시키게 된다.Of course, if the result is a defective product, the conveyor 32 is to move the defective collection unit of the collection box 30 to the copper reducer 50 falling position.

이상 설명한 바와 같은 본 발명에 따른 동흡진기 선별장치에 의하면, 간단한 구조로 동흡진기의 주파수 특성치를 보다 간편하게 검사할 수 있게 됨으로써, 정확하게 튜닝된 동흡진기만을 차량에 사용할 수 있게 된다.According to the apparatus for screening a dynamic reducer according to the present invention as described above, the frequency characteristic value of the dynamic reducer can be more easily inspected with a simple structure, so that only the accurately tuned dynamic reducer can be used in a vehicle.

또한, 검사에 소요되는 시간과 노력을 줄여 생산성을 높이고 원가를 절감할 수 있는 효과를 얻게 된다.In addition, the time and effort required for inspection can be reduced to increase productivity and reduce costs.
