Abstract

이 발명은 VCR드럼의 구멍가공장치에 있어서 그 일부분을 이루는, 드럼에 가공될 구멍의 위치를 결정해 주는 구멍가공위치 결정장치에 관한 것으로, 기판(10)의 일측에 축관통공을 가진 축수관(11)과 회전제어구(12)를 적층고정하고 상기 회전제어구(12)의 상부에는 걸림홈(12a)과 풀리설치부(12b)를 형성하되, 상기 풀리설치부(12b)에는 모터(14)에 의해 구동되는 종동풀리(13)를 공회전 가능하게 설치하고, 상기 축수관(11)과 회전제어구(12)의 축관통공에는 회전축을 관통시키되 회전축(17)의 상단에는 원판(18)을 고정하고 원판(18)의 일측에는 핀(19)을 하향설치하여 이 핀(19)이 종동풀리 (13)를 관통함과 동시에 그 하단이 회전제어구(12)의 걸림홈(12a)까지 연장되게 하고, 중앙에 삽입봉(21)이 형성되고 그 주변 일측에 방향결정핀(22)이 스프링(22a)에 의해 탄성적으로 설치되어 있는 드럼장착구(20)를 상기 회전축(17)의 하단에 고정설치하는 한편, 회전축(17)은 상기 핀(19)이 검림홈(12a)으로부터 벗어날수 있을 정도로 상승되도록 유격을 두어 설치하되 드럼 장착구(20)와 축수관(11) 사이에 스프링(23)을 거재하여서된 특징이 있다.The present invention relates to a hole processing positioning device for determining the position of the hole to be machined in the drum, a part of the hole processing device of the VCR drum, the bearing tube having a shaft through hole on one side of the substrate ( 11) and the rotation control tool 12 is laminated and fixed to the upper portion of the rotation control tool 12 to form a locking groove 12a and the pulley mounting portion 12b, the motor (14) in the pulley mounting portion 12b Drive driven pulley (13) driven by idling) and the shaft through-hole of the bearing pipe (11) and the rotary control tool (12) through the rotating shaft, but the disc 18 on the upper end of the rotating shaft (17) The pin 19 is installed downward on one side of the disc 18 so that the pin 19 penetrates the driven pulley 13 and the lower end thereof extends to the locking groove 12a of the rotation control tool 12. Insertion rod 21 is formed in the center, and the direction pin 22 is elastically by the spring 22a on one side thereof. The drum mounting hole 20 is fixed to the lower end of the rotary shaft 17, while the rotary shaft 17 is installed with a clearance such that the pin 19 is raised to escape from the black groove 12a. But it is characterized by the spring 23 is interposed between the drum mounting hole 20 and the water-retaining pipe (11).

Description

VCR drum hole positioning device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 하부드럼위치를 결정해주는 장치의 한 실시예의 개략적인 단면도.1 is a schematic cross-sectional view of one embodiment of an apparatus for determining the lower drum position of the present invention.

Claims

On one side of the substrate 10, a shaft fixing hole 11 having a shaft through-hole and a rotation control tool 12 are laminated and fixed, and a locking groove 12a and a pulley mounting part 12b are disposed on an upper part of the rotation control tool 12. It is formed, but the pulley mounting portion 12b is installed in the driven pulley 13 driven by the motor 14 so as to be rotatable, and the rotating shaft is provided in the shaft through-hole of the bearing tube 11 and the rotary control tool 12 While penetrating, the disc 18 is fixed to the upper end of the rotary shaft 17, and the pin 19 is installed downward on one side of the disc 18 to penetrate the driven pulley 13 of the pin 19 and at the same time the lower end thereof. It extends to the engaging groove 12a of the rotation control tool 12, the insertion rod 21 is formed in the center and the direction determining pin 22 is elastically installed by the spring 22a on one side thereof. While the drum mounting hole 20 is fixedly installed at the lower end of the rotary shaft 17, the rotary shaft 17 is raised so that the pin 19 can escape from the locking groove 12a. Installed at a distance so as to win, but the hole processing position determination device of the VCR drum, characterized in that the intervening between the spring mounting hole (20) and the bearing pipe (11).

The apparatus of claim 1, wherein the drum mounting holes (20) are dualized between the upper drum mounting holes (20B) and the lower drum mounting holes (20A).
