본 고안은 브이씨알 등에 사용되는 헤드드럼에 관한 것으로, 특히 트랜스 캡 조정이 용이하게 한 헤드드럼 트랜스 캡 조정장치에 관한 것이다.The present invention relates to a head drum used in the V-Cal or the like, and more particularly to a head drum trans cap adjusting device that facilitates the trans cap adjustment.
종래 헤드드럼은 제1도에 도시한 바와 같이 하부드럼(1)에 고정트랜스(2)를 접착제로 부착하는 한편, 플랜지(3)와 축(4)을 지그에 넣고 압입하여 결합한 후 회전트랜스(5)에 접착제를 도포하고 상기 축(4)을 압입시킨 플랜지(3)와 함께 지그에 넣고 회전트랜스(5)를 부착한 하부드럼(1)에 조립체를 완성하여 이후 고정트랜스(5)를 부착한 하부드럼(1)에 플랜지 조립체를 삽입하고 플랜지 조립체가 빠지지 않도록 하부드럼(1) 하축부의 축(4)에 링칼라(6)를 세트스크류(7)로 고정하는 과정으로 조립하도록 되어 있다.In the conventional head drum, as shown in FIG. 1, the fixed transformer 2 is attached to the lower drum 1 with an adhesive, while the flange 3 and the shaft 4 are inserted into the jig, press-fitted, and then coupled to the rotating transformer ( 5) The adhesive is applied to the jig together with the flange (3) in which the shaft (4) is press-fitted, and the assembly is completed on the lower drum (1) to which the rotary transformer (5) is attached, and then the fixed transformer (5) is attached. The flange assembly is inserted into one lower drum 1, and the ring collar 6 is fixed to the shaft 4 of the lower shaft 1 of the lower drum 1 with the set screw 7 so that the flange assembly does not fall out. .
또한 이와 같은 조립을 하면서 고정트랜스(2)가 접착된 하부드럼(1)에 플랜지 조립체를 결합할 때 하부드럼(1)의 상부 즉, 플랜지 조립체가 닿는 부분에서 고정트랜스(2)까지의 거리와 회전트랜스(5)면에서 하부드럼(1)이 닿는 부분의 거리를 측정하여 트랜스 갭의 사양인 50㎛에 맞도록 와셔를 넣고 이 상태에서 베어링(8)의 예압을 행함과 아울러 링칼라 고정지그에 놓고 링칼라(6)를 세트스크류(7)로 고정한다.In addition, when the flange assembly is coupled to the lower drum 1 to which the fixed transformer 2 is bonded during such assembly, the distance from the upper portion of the lower drum 1, that is, the flange assembly to the fixed transformer 2, Measure the distance of the part where the lower drum 1 touches from the surface of the rotating transformer 5, insert a washer to meet the specification of 50 µm of the transgap, and preload the bearing 8 in this state. And fix the ring collar (6) with the set screw (7).
그러나 종래의 헤드드럼에 있어서는 갭 조정작업이 매우 까다로우므로 정확성을 기하기 어려웠다.However, in the conventional head drum, it is difficult to achieve accuracy because gap adjustment is very difficult.
따라서 트랜스 캡의 오차로 인한 문제점이 유발되었다.Therefore, the problem caused by the error of the trans cap was caused.
즉, 트랜스 캡이 규정치 보다 커서 화면굴곡현상이 일어나고 화질이 저하되며, 또 작아서 헤드드럼의 회전이 불안하고 화질과 지터(Jiter)등이 악화되는 문제점이 있었고, 또 하부드럼에 고정트랜스 접착시 정확히 정착되지 않거나 접착제가 하부드럼에 흘러나와 헤드드럼의 회전이 불가능하게 되는 문제점이 있었다.In other words, because the trans cap is larger than the specified value, the screen bends and the image quality is deteriorated. Also, because the trans cap is small, the rotation of the head drum is unstable and the image quality and jitter are deteriorated. There was a problem that the fixing is not fixed or the adhesive flows to the lower drum is impossible to rotate the head drum.
본 고안은 이러한 종래의 문제점을 해결하기 위하여 안출된 것으로 이를 첨부도면에 도시한 실시예에 따라서 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a conventional problem and described in detail according to the embodiment shown in the accompanying drawings.
제2도는 본 고안에 의한 헤드드럼의 종단면도이고, 제3도는 본고안 장치의 구성을 보인 분해 단면도로서, 이에 도시한 바와 같이, 하부드럼(1)에 고정트랜스(2)가 고정되고, 플랜지(3)에 압입된 축(4)이 하부드럼(1)에 회전가능하게 결합되며, 플랜지(3) 하면에는 회전트랜스(5)가 고정된다.Figure 2 is a longitudinal cross-sectional view of the head drum according to the present invention, Figure 3 is an exploded cross-sectional view showing the configuration of the present design device, as shown, the fixed transformer 2 is fixed to the lower drum 1, the flange The shaft 4 press-fitted to the (3) is rotatably coupled to the lower drum (1), the rotation transformer 5 is fixed to the lower surface of the flange (3).
상기 고정트랜스(2)의 중간부에 나사홈(2a)을 형성하고 하부드럼(1)에는 나사홈(2a)과 연통되는 고정공(1a)을 형성하여 고정트랜스(2)와 하부드럼(1)사이에 압축스프링(9)을 끼움과 아울러 하부드럼(1) 하부에 와셔(10)을 끼우고 나사(11)로 고정한다.A screw groove 2a is formed in the middle of the fixed transformer 2, and a lower hole 1 is formed with a fixing hole 1a communicating with the screw groove 2a to fix the fixed transformer 2 and the lower drum 1. In addition to the compression spring (9) between the fitting the washer (10) to the lower drum (1) lower and secure with screws (11).
도면에서 종래의 구성한 동일한 부분에 대하여는 동일 부호로 표시하였다.In the drawings, the same parts constituted in the related art are denoted by the same reference numerals.
이와같이 구성된 본 고안의 트랜스 캡 조정장치가 적용된 헤드드럼의 조립과정을 설명하면, 먼저, 하부드럼(1)에 스프링(9)과 와셔(10)를 나사(11)로 고정한다.Referring to the assembly process of the head drum to which the trans-cap adjusting device of the present invention configured as described above is applied, first, the spring 9 and the washer 10 are fixed to the lower drum 1 with the screws 11.
이후 플랜지 조립체를 하부드럼(1)에 조립하면서 트랜스 캡이 사양 규격치(50㎛)에 거의 맞도록 50㎛인 간격 조정동판을 트랜스 캡에 골라 넣고 나사(11)를 조인 후 동판을 빼낸다.Then, while assembling the flange assembly to the lower drum (1), select a 50㎛ spacing adjusting copper plate in the trans cap so that the trans cap almost fits the specification specification value (50㎛), tighten the screws 11 and remove the copper plate.
이상과 같이 본 고안은 스프링과 나사를 이용하여 고정트랜스를 하부드럼에 고정시키는 것이므로 작업성이 개선되고 접착제를 사용하지 않으므로 접착제가 흘러나옴에 따른 결합이 배제된다.As described above, the present invention is to fix the fixed transformer to the lower drum by using a spring and a screw, so workability is improved, and the adhesive is not used, and thus the bonding is eliminated.
또한 하부드럼 가공시 규정치수와 상이하게 가공된 경우에도 고정트랜스의 상하 간격을 조정할 수 있게 되므로 트랜스 캡을 정확히 조정할 수 있다.In addition, the upper and lower intervals of the fixed transformer can be adjusted even when the lower drum is processed differently from the prescribed size, so that the trans cap can be precisely adjusted.
따라서 화질이 좋아지고 신호의 전달도 양호하게 된다.Therefore, image quality is improved and signal transmission is also good.
