본 고안은 비디오 카세트 레코더용 비디오 헤드베이스의 고정장치에 관한 것으로, 특히 헤드드럼의 상측회전드럼에 고정되는 헤드베이스의 체결공과 그 헤드베이스를 회전드럼에 체결시키는 볼트의 체결구조를 분할구조로 하여 조립작업 및 자세교정이 용이하고 가공작업의 향상을 기할 수 있게한 브이씨알의 헤드베이스 고정장치에 관한 것이다.The present invention relates to a fastening device of a video head base for a video cassette recorder, and in particular, a fastening structure of a head base fixed to an upper rotating drum of a head drum and a fastening structure of a bolt for fastening the head base to a rotating drum as a divided structure. It is related with the head base fixing device of V-CAL which facilitates assembly work and posture correction and improves the machining work.
종저에도 헤드드럼의상축 회전드럼에 설치되는 헤드베이스는 그 높이 및 자세를 교정할 수 있도록 되어있었으나, 이는 헤드베이스 1개당 2개의 조정구멍이 별도로 형성되어 있어 자세교정시에 렌치를 각각의 조정구멍에 끼워 헤드베이스의 자세를 조정토록 되어 있으므로, 자세교정 작업이 번거롭고 정확한 조정이 까다로웠으며, 하나의 헤드드럼에 다수의 헤드가 부착되는 경우에 있어서는 헤드수에 비례하여 조정구멍이 늘어나므로 상측 회전드럼의 가공시 그 제조가공작업이 복잡해지는 문제점을 안고 있었다.Even at the bottom, the head base that is installed on the rotating drum of the head drum was able to correct its height and posture.However, two head adjustment holes are provided for each head base. Since the posture of the head base is adjusted to fit the position, the posture correction work is cumbersome and difficult to adjust.In the case where a large number of heads are attached to one head drum, the adjustment hole is increased in proportion to the number of heads so that the upper rotation is performed. The manufacturing process of the drum had a problem that the manufacturing work is complicated.
본 고안은 이와같은 종래의 문제점을 감안하여 헤드베이스의 체경공 및 체결볼트의 구조를 개량함으로써 체결작업 및 자세교정이 간단 용이하게하고 제조가공도 줄일수 있게하여 생산성을 높일수 있도록 안출한 것으로 이를 첨부도면에 의하여 설명하면 다음과 같다.The present invention has been made to improve productivity by improving the structure of the body diameter hole and the fastening bolt of the head base to simplify the fastening operation and posture correction and to reduce the manufacturing process in view of such a conventional problem. Referring to the drawings as follows.
본 고안을 분해한 제1도에서와 같이 헤드드럼의 상측회전드럼(1)에 나선공(1-1)과 헤드베이스(2)의 고정공(1-2) 및 회전축공(1-3), 헤드창(1-4)을 형성하고, 헤드베이스(2)의 중앙에는 각주가 삽입될 수 있도록형의 분할형 체결공(2-1)을 형성하며, 헤드베이스(2)를 상측 회전드럼(1)에 체결하는 체결볼트(3)의 축부(3-1)를 분할하여 이의 길이 방향으로 6각형의 각주형홀(3-2)을 형성한 것으로, 미설명부호 4는 너트를 보인 것이고, 5는 헤드베이스(2)의 높이를 조절하는 스크류를 보인 것이다.As shown in FIG. 1 in which the present invention is disassembled, the fixing hole (1-2) and the rotating shaft hole (1-3) of the spiral hole (1-1) and the head base (2) in the upper rotating drum (1) of the head drum. To form a head window (1-4), so that the footnote can be inserted in the center of the head base (2) A split type fastening hole (2-1) of a die shape, and the shaft portion (3-1) of the fastening bolt (3) for fastening the head base (2) to the upper rotating drum (1) is divided into 6 in the longitudinal direction thereof. The square-shaped square hole 3-2 is formed, and reference numeral 4 shows a nut, and 5 shows a screw for adjusting the height of the head base 2.
그리고 제2도에서와 같이 상측 회전드럼(1)하부에 헤드베이스(2)를 분할체결볼트(3)와 너트(4)로 체결하는 것이며 나선공(1-1)에는 스크류(5)를 나입시켰다. 또한, 제4도에서와같이 헤드베이스(2)에는 분할형 체결공(2-1)의 양 내측에는 각주가 걸리게 돌출부(2-1a)를 구성하고 헤드(2-2), 헤드출력선(2-3), 프린트 회로기판(2-4)을 구비하고 있는 것이다.Then, as shown in Fig. 2, the head base 2 is fastened to the lower base of the upper rotating drum 1 with the divided fastening bolt 3 and the nut 4, and the screw 5 is inserted into the spiral hole 1-1. I was. In addition, as shown in FIG. 4, the head base 2 constitutes protrusions 2-1a on both inner sides of the divided fastening holes 2-1, and includes the head 2-2 and the head output line ( 2-3) and a printed circuit board 2-4.
그리고 제2도의 육각렌치(6)는 자세교정공구로서 사용된다. 이와같이 된 본 고안의 작용효과를 보면 제2도에서와 같이 분할형으로된 체결볼트(3)와 너트(4)로 헤드베이스(2)를 체결하는데 분할 체결볼트(3)에는 6각형으로된 가주형홀(3-2)과 헤드베이스(2)에는 돌출부(2-1a)가 형성되어 있어 헤드베이스(2)와 분할 체결볼트(3)가 선택적으로 결합되어 유동이 되지 않으며 안정되고 견고히 체결이 되는 것이다.The hexagon wrench 6 in FIG. 2 is used as a posture corrector. As shown in FIG. 2, the head bolts 2 are fastened to the split bolts 3 and the nut 4. The split bolts 3 are hexagonal. Protruding portion 2-1a is formed in the mold hole 3-2 and the head base 2 so that the head base 2 and the divided fastening bolt 3 are selectively coupled to prevent flow and are fastened stably and firmly. will be.
한편, 헤드베이스(2)의 체결시나 자세교정시에는 제2도에 도시한 바와같이 육각렌치(6)를 분할체결볼트(3)내에 끼우면 육각렌치(6)의 하부가 축부(3-1)의 내면에 결합되는 동시에, 헤드베이스의 돌출부(2-1a)에도 걸리어 회전이 가능하게 되므로 육각렌치(6)로서 체결볼트(3)는 물론 헤드베이스(2)도 회전시켜 임의의 위치로 자세를 간단 용이하게 교정시킬 수 있는 것이다.On the other hand, when the head base 2 is tightened or the posture is corrected, as shown in FIG. 2, when the hex wrench 6 is inserted into the divided fastening bolt 3, the lower portion of the hex wrench 6 becomes the shaft portion 3-1. Is coupled to the inner surface of the head base, and is also caught by the protrusions 2-1a of the head base, so that the rotation is possible. As the hexagonal wrench 6, the fastening bolt 3 as well as the head base 2 are rotated to form an arbitrary position. Can be easily and easily calibrated.
한편, 제7도는 제2도의 A-A선 단면도로서 상기의 내용을 보다 구체적으로 보여주고 있다. 즉, 헤드베이스(2)를 헤드드럼(1)에 체결하기 위하여 구성된 체결공(2-1)과 볼트(3)의 상호구성을 보여준다.On the other hand, Figure 7 is a cross-sectional view taken along the line A-A of Figure 2 shows more specifically the above. That is, it shows the mutual configuration of the fastening hole (2-1) and the bolt (3) configured to fasten the head base (2) to the head drum (1).
제7도에서와 같이 체결공(2-1)에 볼트(3)를 결합시키게 되면 볼트(3)의 축부(3-1)는 체결공(2-1)의 내부에 위치하게 되고, 이때 육각렌치(6)를 축부(3-1)의 내면에 결합시키면 육각렌치(6)의 하단부가 체결공(2-1)의 돌출부(2-1a)에 걸리게 된다.As shown in FIG. 7, when the bolt 3 is coupled to the fastening hole 2-1, the shaft portion 3-1 of the bolt 3 is positioned inside the fastening hole 2-1, and the hexagon When the wrench 6 is coupled to the inner surface of the shaft portion 3-1, the lower end of the hexagon wrench 6 is caught by the protrusion 2-1a of the fastening hole 2-1.
따라서 육각렌치(6)를 회전시키게 되면 헤드베이스(2)도 동시에 회전하게 되어 자세조정을 할 수 있도록 되어진다.Therefore, when the hexagon wrench 6 is rotated, the head base 2 is also rotated at the same time so that the attitude can be adjusted.
이상에서 상술한 바와같은 본 고안은 헤드베이스와 체결볼트에 분할형 체결구조를 개입시켜 자세교정이 간단하고, 종전의 자세교정 구멍을 줄일수 있어 가공작업량을 대폭 줄이며 나사공 등의 가공도 생략할 수 있는 등의 생산성도 높은 것이고, 헤드베이스의 자세교정이 용이하여 헤드의 성능효과 측정도 용이하여 지는등의 이점을 제공해준다.The present invention as described above, through the split-type fastening structure through the head base and the fastening bolt, the posture correction is simple, and the conventional posture correction hole can be reduced, which greatly reduces the amount of processing work and also eliminates the machining of screw holes. It is also highly productive, and it is easy to posture correction of the head base, so that it is easy to measure the performance effect of the head.
