Abstract

본 발명은 광픽업 액츄에이터의 요크 플레이트 정밀도 측정장치(10)에 관한 것으로, 상부에 형성한 축 삽입공(1)의 전후면으로는 절개홈(5A,5B)을 형성하고 하부에는 고정캡(2)이 체결되도록 나사공(3)을 형성하였으며 상기한 축삽입공(1)과 나사공(3)의 사이에는 사각통공(4)을 형성한 받침블록(5)과, 상기한 받침블록(5)의 축삽입공(1)으로 삽입되어 나사공(3)을 통해 하부로 돌출되며 상부에는 고정너트(6B)가 체결되도록 나사부(6A)를 형성하고 중심부에는 사각부(6C)를 형성한 샤프트(6)와, 중심부에는 샤프트(6)가 삽입되도록 관통공(7)을 형성하고 하부에는 구면홈(8)을 형성한 측정부재(9)와, 받침블록(5)의 하부에 설치되어 샤프트(6)와의 접촉에 따라 판스프링(11)과 접점(12,13)이 연결됨으로써 작동하도록 한 경보기(15)로 이루어져 측정부재(9)를 받침블록(5)의 상부에 안치된 요크 플레이트(Ｙ)와 밀착시켜 요크 플레이트(Ｙ)의 구면 돌기(32)에 대한 정밀도를 측정함으로써 요크 플레이트(Ｙ)의 구면돌부(32)에 대한 정밀도 측정작업을 신속하고 용이하게 할 수 있는 동시에, 구면돌부(32)에 대한 정밀도 측정작업이 정확하게 이루어질 수 있도록 구성한 것이다.The present invention relates to a yoke plate precision measuring apparatus (10) for an optical pickup actuator, wherein cutting grooves (5A, 5B) are formed on the front and rear surfaces of a shaft insertion hole (1) A support block 5 having a square hole 4 formed between the shaft insertion hole 1 and the screw hole 3 and a support block 5 A threaded portion 6A is formed so as to be inserted into the shaft insertion hole 1 of the shaft hole 1 and protruded downward through the screw hole 3 and a fixing nut 6B is fastened to the upper portion, A measurement member 9 having a through hole 7 formed at the center thereof to receive the shaft 6 and a spherical groove 8 formed at the bottom thereof and a measurement member 9 provided at the bottom of the support block 5, And an alarm 15 which is operated by connecting the leaf springs 11 and the contacts 12 and 13 in accordance with the contact between the plate spring 11 and the contacts 6, The precision measurement of the spherical protrusion 32 of the yoke plate Y can be quickly and easily performed by measuring the accuracy of the spherical protrusion 32 of the yoke plate Y by bringing the yoke plate Y into close contact with the yoke plate Y And the precision measurement of the spherical protrusion 32 can be accurately performed.
