It relates to a device for measuring the straightness of the actuator yoke.
종래 엑츄에이터 요크의 폴(POLE)의 직진성을 측정하기 위하여는 3차원 측정기로 각각의 폴의 3곳 이상을 측정하여 평탄도를 계산하거나, 또는 기타 도구를 사용하여 폴의 직진도를 측정하여야 했기 때문에, 요크의 직전도를 측정하는데 상당히 많은 시간이 걸릴 뿐만 아니라 정확도가 떨어지는 문제가 있었다.In order to measure the linearity of the pole of the conventional actuator yoke, it is necessary to calculate the flatness by measuring three or more points of each pole with a three-dimensional measuring instrument, or to measure the straightness of the pole using other tools. In addition, it took a lot of time to measure the conductivity of the yoke, and there was a problem of poor accuracy.
본 고안은 이와 같은 종래 엑츄에이터 요크의 직진도 측정에 있어서의 문제점을 해결하기 위하여 안출한 것으로, 엑츄에이터 요크의 직진도를 자동적으로 정확하게 측정할 수 있는 엑츄에이터 요크의 직진도 측정장치를 제공하는데 그 목적이 있다.The present invention has been made to solve such a problem in the measurement of the straightness of the conventional actuator yoke, and to provide an actuator yoke straightness measuring device that can automatically and accurately measure the straightness of the actuator yoke. have.
이와 같은 목적을 달성하기 위한 본 고안은, 요크의 폴이 삽입될 수 있는 복수의 수직 홈이 형성된 지그와, 상기 지그의 각각의 홈에 수직으로 4개씩 설치되어 요크의 폴에 접촉하여 눌려져 전류량을 변화시키는 압전소자와, 상기 압전소자에 의해 감지된 전류량 변화를 일정레벨로 증가시키는 증폭수단과, 상기 증폭수단에 의해 증폭된 아날로그적인 전류량 변화를 디지털화시키는 A/D콘버터와, 상기 A/D콘버터의 출력을 기준치와 비교하여 기준치보다 클 때에는 '불량'으로 디스플레이시키고 기준치보다 작을 때에는 '양호'로 디스플레이시키도록 제어하는 마이컴과, 상기 마이컴의 출력을 디스플레이시키는 디스플레이부로 구성한 것을 특징으로 한다.The present invention for achieving the above object, the jig is formed with a plurality of vertical grooves can be inserted into the pole of the yoke, and each of the four vertically installed in each groove of the jig is pressed in contact with the pole of the yoke to reduce the amount of current A piezoelectric element for changing, an amplifying means for increasing a change in the amount of current sensed by the piezoelectric element to a constant level, an A / D converter for digitizing the change in analog current amount amplified by the amplifying means, and the A / D converter Compared to the reference value of the output value of the reference value 'bad' and when the value is smaller than the reference value, the microcomputer for controlling to display the display, and the display unit for displaying the output of the microcomputer.
이하, 본 고안 엑츄에이터 요크의 직진도 측정장치의 바람직한 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the device for measuring the straightness of the actuator yoke of the present invention will be described in detail as follows.
제1도는 본 고안에 따른 엑츄에이터 요크의 직진도 측정용 지그의 개략적인 구성도로서, 지그(1)에 요크(2)의 폴(3)이 삽입될 수 있도록 수직으로 복수의 홈(4)들이 형성되어 있다.FIG. 1 is a schematic configuration diagram of a jig for measuring straightness of an actuator yoke according to the present invention, in which a plurality of grooves 4 are vertically inserted so that the pole 3 of the yoke 2 may be inserted into the jig 1. Formed.
또한, 상기 지그(1)의 각각의 홈(4)에 수직방향으로 압전소자(5)가 4개씩 설치되어 있어서 요크(2)의 폴(3)이 홈(4)에 삽입될 때 압전소자(5)가 폴(3)의 직진도에 따라 눌려져서 전류량의 변화를 검출하게 된다.Further, four piezoelectric elements 5 are provided in the grooves 4 of the jig 1 in the vertical direction so that when the poles 3 of the yoke 2 are inserted into the grooves 4, the piezoelectric elements ( 5) is pressed according to the straightness of the pole 3 to detect a change in the amount of current.
여기서, 압전소자(5)를 각각의 홈(4)에 4개씩 설치하는 것은 요크(2)의 어느 하나의 폴(3)이 수직으로 형성되지 않고 비스듬히 형성되어 있는 경우에, 폴(3)의 직진도를 하단 및 상단에서 정확히 측정하기 위한 것이다.Here, the four piezoelectric elements 5 are provided in each of the grooves 4 in the case where any one of the poles 3 of the yoke 2 is formed at an angle rather than vertically. Straightness is to be measured accurately at the bottom and top.
제2도는 본 고안에 따른 엑츄에이터 요크의 직진도 측정장치의 블록도로, 상기 압전소자(5)에 의해 감지된 전류량 변화를 일정레벨로 증가시키는 증폭수단(6)과, 상기 증폭수단(6)에 의해 증폭된 아날로그적인 전류량 변화를 디지털화시키는 A/D콘버터(7)와, 상기 A/D콘버터(7)의 출력을 기준치와 비교하여 기준치보다 클 때에는 '불량'으로 디스플레이시키고 기준치보다 작을 때에는 '양호'로 디스플레이시키도록 제어하는 마이컴(8)과, 상기 마이컴(8)의 출력을 디스플레이시키는 디스플레이부(9)를 구비한다.2 is a block diagram of an apparatus for measuring the straightness of an actuator yoke according to the present invention. The amplification means 6 increases the amount of current detected by the piezoelectric element 5 to a predetermined level. The A / D converter 7 which digitizes the change in the amount of analog current amplified by the digital signal, and the output of the A / D converter 7 are displayed as 'bad' when larger than the reference value and 'good' when smaller than the reference value. And a display unit 9 for displaying the output of the microcomputer 8.
이와 같이 구성된 본 고안은 엑츄에이터 요크의 직진도 측정시, 먼저 지그(1)를 제1도와 같이 위치시키고 요크(2)의 폴(3)을 지그(1)의 홈(4)에 일치되게 하방에서 상방으로 삽입시킨다.When the straightness of the actuator yoke is measured as described above, the jig 1 is first positioned as shown in FIG. 1 and the pole 3 of the yoke 2 is aligned with the groove 4 of the jig 1. Insert upward.
이때, 요크(2)의 폴(3)이 홈(4)에 삽입되면서 폴(3)의 수직면에 접촉하는 압전소자(5)가 압력을 받아 눌려지게 되는데, 직진도가 양호할 때에는 압전소자(5)의 눌려지는 압축량이 적으므로 전류량 변화가 작게 되고, 직진도가 불량할 때에는 압전소자(5)의 눌려지는 압축량이 많으므로 전류량 변화가 크게 된다.At this time, as the pole 3 of the yoke 2 is inserted into the groove 4, the piezoelectric element 5 contacting the vertical surface of the pole 3 is pressed under pressure. When the straightness is good, the piezoelectric element ( Since the amount of compression that is pressed in 5) is small, the change in the amount of current is small, and when the straightness is poor, the amount of compression is large because the amount of compression in the piezoelectric element 5 is pressed.
따라서, 이와 같은 압전소자(5)에 의해 전류가 변화가 검출되면, 이러한 전류량 변화가 증폭수단(6)에 의해 일정레벨로 증폭된 후 A/D콘버터(7)에 의해 디지털화되어 마이컴(8)에 입력된다.Therefore, when a change in current is detected by the piezoelectric element 5, the change in the amount of current is amplified to a certain level by the amplifying means 6, and then digitized by the A / D converter 7 and the microcomputer 8 Is entered.
그러면 마이컴(8)에서는 A/D콘버터(7)에서 디지털화된 전류량을 기설정되어 있는 기준치와 비교하여 기설정되어 기준치보다 작으면 '양호'로 판단하고, 기준치보다 크면 '불량'으로 판단한다.Then, the microcomputer 8 compares the amount of current digitized in the A / D converter 7 with a preset reference value and determines that the result is 'good' if it is smaller than the reference value, and determines that it is 'bad' if it is larger than the reference value.
즉, 요크(2)의 폴(3) 수직면의 직진도가 불량할 때(수직면이 많이 휘어져 있을 때)에는 압전소자(5)의 전류량 변화가 많이 일어나 기준치보다 크게 되므로, 이때에는 마이컴(8)에서 폴(3)의 직진도가 불량한 것으로 판단하여 디스플레이부(9)를 통하여 '불량'이라고 디스플레이하게 된다.That is, when the straightness of the vertical surface of the pole 3 of the yoke 2 is poor (when the vertical surface is bent a lot), the current amount of the piezoelectric element 5 changes a lot and becomes larger than the reference value. In this case, the straightness of the pole 3 is determined to be poor, and the display unit 9 displays 'bad'.
반대로 요크(2)의 폴(3) 수직면의 직진도가 양호할 때에는 압전소자(5)의 전류량 변화가 작게 일어나 이러한 전류량 변화가 기준치보다 작게 되므로, 이때에는 마이컴(8)에서 폴(3)의 직진도가 양호한 것으로 판단하여 디스플리에부(9)를 통하여 '양호'라고 디스플레이하게 된다.On the contrary, when the straightness of the vertical surface of the pole 3 of the yoke 2 is good, the change in the amount of current of the piezoelectric element 5 is small and the change in the amount of current is smaller than the reference value. The straightness is judged to be good, and is displayed as 'good' through the display unit 9.
이상에서 설명한 바와 같이 종래에는 3차원 측정기를 사용하여 요크(2)의 폴(3)의 각각의 면을 측정하거나 또는 기타 도구를 사용하여 측정하여야 했기 때문에 정확도가 떨어질 뿐만 아니라 상당히 많은 시간이 걸렸으나, 본 고안에 의하면 요크(2)의 폴(3)을 지그(1)의 홈(4)에 간단히 삽입시키기면 하면 자동적으로 폴(3)의 직진도를 측정할 수 있어 측정하기가 용이할 뿐만 아니라 폴(3)의 직진도를 정확히 측정할 수 있는 효과가 있다.As described above, in the related art, since each side of the pole 3 of the yoke 2 has to be measured using a three-dimensional measuring instrument or another tool, the accuracy is not only reduced, but also takes a considerable time. According to the present invention, if the pawl 3 of the yoke 2 is simply inserted into the groove 4 of the jig 1, the straightness of the pawl 3 can be measured automatically, and the measurement is easy. But it is effective to accurately measure the straightness of the pole (3).
