본 고안은 브이씨알의 헤드드럼장치에 관한 것으로, 특히 하드럼의 테이프 주행부 및 리드라인부를 사출물로 구성하여 제작이 용이하고, 온,습도의 영향에 의하여 치수와 형상정도가 변화되지 않도록 한 브이씨알의 헤드드럼장치에 관한 것이다.The present invention relates to a head drum device of V-Cal. In particular, the tape running part and the lead line part of the hard drum are made of an injection molded product, which is easy to manufacture, and the size and shape of the V drum are not changed by the influence of temperature and humidity. It relates to a head drum device of the seed.
종래 브이씨알의 헤드드럼의 구조는, 제 1 도에 도시한 바와 같이, 하드럼(2)에 회전가능하게 지지된 샤프트(3)의 상단에는 상드럼(1)이 고정설치되고, 상드럼(1)에는 헤드(4)가 설치되며, 상드럼(1)의 저면과 하드럼(2)의 상면에는 트랜스(5)의 로터와 스테이터가 각각 고정되고, 하드럼(2)의 하부에는 실드케이스(8)이 설치되어 모터스테이터(7)가 고정설치되며, 샤프트(3)의 하단에는 모터로터(6)가 설치되는 것이다.As shown in FIG. 1, the head drum of the conventional V-Cal has a top drum 1 fixed to an upper end of the shaft 3 rotatably supported by the hard drum 2, and the top drum ( 1) a head 4 is installed, a rotor and a stator of the transformer 5 are fixed to the bottom of the upper drum 1 and the top of the hard rum 2, respectively, and a shield case to the bottom of the hard rum 2, respectively. (8) is installed, the motor stator (7) is fixed, and the motor rotor (6) is installed at the lower end of the shaft (3).
그러나 이러한 종래의 브이씨알 등의 자기기록장치에 사용되고 있는 헤드드럼을 제작함에 있어서는 알루미늄합금(Al, Si, Cu, Mg…)을 단조한 다음 절삭가공하여 완성하는 것으로, 특히 하드럼(2)의 테이프주행부 및 리드라인(Lead Line)부(9)를 절삭 가공하기 위하여 캠형상을 갖는 리드 가공 전용의 정밀 선반을 사용하고 있으며, 가공시에는 제 2 도 및 제 3 도에 도시한 바와 같이, 단속된 절삭으로 30∼40회에 걸쳐서 가공해야 하기 때문에 제작상 어려움이 많았을 뿐만 아니라 제작비용이 상승하게 되는 문제점이 있었다.However, in manufacturing a head drum used in a conventional magnetic recording apparatus such as BC-AL, forging aluminum alloys (Al, Si, Cu, Mg…), and then cutting and finishing them, in particular, In order to cut the tape running portion and the lead line portion 9, a precision lathe dedicated for lead processing having a cam shape is used, and as shown in FIGS. 2 and 3 during machining, Because of the interrupted cutting to be processed 30 to 40 times, there was a problem that the production cost increases as well as a lot of manufacturing difficulties.
또한 종래에는 하드럼(2)이 알루미늄합금으로 제작되어 있으므로 온,습도의 영향으로 테이프 주행부의 치수나 형상정도가 변화되어 헤드드럼의 성능이 저하되거나 제기능을 수행할 수 없게 되는 문제점이 있었다.In addition, conventionally, since the hard rum 2 is made of aluminum alloy, the size and shape accuracy of the tape running portion are changed due to the influence of temperature and humidity, thereby degrading the performance of the head drum or being unable to perform proper functions.
따라서 본 고안은 상술한 바와 같은 종래의 문제점을 해결하기 위하여 하드럼의 테이프 주행부 및 리드라인부를 사출물로 구성하여 대량생산이 가능하게 되며, 제작원가를 절감할 수 있도록 한 브이씨알의 헤드드럼장치를 제공함을 목적으로 하는 것이다.Therefore, in order to solve the above-mentioned problems, the present invention can be mass-produced by configuring the tape running part and the lead line part of the hard rum, and the head drum device of V-CAL can reduce the manufacturing cost. It is intended to provide.
본 고안의 다른 목적은 온,습도의 영향에 의하여 치수나 형상 정도가 변화되는 일이 없어 제기능을 발휘할 수 있도록 하려는 것이다.Another object of the present invention is to make it possible to exert its function without changing the dimensions or the degree of shape by the influence of temperature and humidity.
이하 본 고안에 의한 브이씨알의 헤드드럼장치를 첨부도면에 도시한 실시예에 따라서 상세히 설명한다.Hereinafter, the head drum device of V-Cal according to the present invention will be described in detail according to the embodiment shown in the accompanying drawings.
제 4 도는 본 고안에 의한 브이씨알의 헤드드럼장치의 종단면도로서, 이에 도시한 바와 같이, 하드럼(2)에 회전가능하게 지지된 샤프트(3)의 상단에는 상드럼(1)이 고정설치되고, 상드럼(1)에는 헤드(4)가 설치되며, 상드럼(1)의 저면과 하드럼(2)의 상면에는 트랜스(5)의 로터와 스테이터가 각각 고정되고, 하드럼(2)의 하부에는 실드케이스(8)이 설치되어 모터스테이터(7)가 고정설치되며, 샤프트(3)의 하단에는 모터로터(6)가 설치되어 있다.4 is a longitudinal cross-sectional view of the head drum device of V-Cal according to the present invention, and as shown therein, the upper drum 1 is fixedly installed on the upper end of the shaft 3 rotatably supported by the hard drum 2. The head (4) is installed on the upper drum (1), and the rotor and stator of the transformer (5) are fixed to the bottom of the upper drum (1) and the upper surface of the hard drum (2), respectively. The lower portion of the shield case 8 is installed, the motor stator 7 is fixedly installed, the lower end of the shaft 3 is provided with a motor rotor (6).
상기 하드럼(2)의 외주면에는 테이프 주행부 및 리드라인부(9)가 구비된 플라스틱 사출물로 된 원통체(10)가 압입된다.On the outer circumferential surface of the hard rum 2, a cylindrical body 10 made of a plastic injection molding having a tape running portion and a lead line portion 9 is press-fitted.
여기서 상기 원통체(10)를 사출성형함에 있어서는 헤드드럼에서 요구되는 테이프 주행부와 리드라인부(9)가 형성되도록 사출함으로써 추가 가공(예컨대 종래와 같은 절삭가공)이 필요치 않게 된다.In the injection molding of the cylindrical body 10, the tape running part and the lead line part 9 required for the head drum are formed so that additional processing (for example, cutting process as in the prior art) is unnecessary.
이상과 같이 본 고안에 의하면 테이프 주행부와 리드라인부(9)가 형성된 플라스틱 사출물로 된 원통체(10)를 하드럼(2)의 외주면에 압입설치한 것이므로 원통체(10)를 사출성형할 때 테이프 주행부 및 리드라인부가 형성되도록 하는 금형을 제작하여 사출성형하고 하드럼(2)의 외주면은 단순한 원주면으로 제작하여 원통체(10)를 하드럼(2)에 압입하는 것만으로써 정확한 형상의 테이프 주행부와 리드라인부를 가지는 하드럼(2)을 얻을 수 있어 제작이 용이하게 되고 제작설비비와 제작비용이 절감되는 효과가 있다.As described above, according to the present invention, since the cylindrical body 10 made of a plastic injection molding having the tape running part and the lead line part 9 is press-installed on the outer circumferential surface of the hard rum 2, the cylindrical body 10 cannot be injection molded. In this case, a mold for forming a tape running part and a lead line part is manufactured by injection molding, and the outer circumferential surface of the hard rum 2 is manufactured by a simple circumferential surface, and the cylindrical body 10 is pressed into the hard rum 2 to obtain an accurate shape. It is possible to obtain a hard rum (2) having a tape running portion and a lead line portion of the manufacturing is easy, there is an effect that the manufacturing equipment cost and manufacturing cost is reduced.
또한 본 고안에서는 테이프 주행부와 리드라인부를 구비한 플라스틱 사출물로 된 원통체(10)를 설치한 것이므로 온,습도의 영향에 의하여 테이프 주행부 및 리드라인부의 치수나 형상정도가 변화되는 일이 없어 항상 제기능을 발휘할 수 있게 되는 것이다.In addition, in the present invention, since the cylindrical body 10 made of a plastic injection molding having a tape running part and a lead line part is installed, the size and shape accuracy of the tape running part and the lead line part are not changed by the influence of temperature and humidity. You will always be able to function.
