본 고안은 VTR의 카세트 안착후 비디오카세트의 테이프를 가이드포스트가 인출하여 헤드드럼의 원주에 밀착시키는 로오딩동작시 테이프에 텐숀을 주기위한 텐숀로울러의 후렌지에 있어서 특히 생산수율과 직각도를 향상시키기 위한 후렌지를 개량한 것이다.The present invention improves production yield and squareness, especially in the flange of tension roller to give tension to the tape during the loading operation in which the guide post pulls out the tape of the video cassette after the cassette is seated in the VTR and adheres to the circumference of the head drum. Will improve the Hurenji.
일반적으로 텐숀로울러의 후렌지는 정밀한 치수관리 즉 평판도, 동심도등이 요구되는 것으로 후렌지를 텐숀 아암의 스터드에 삽입한 상태에서 정확한 직각도가 유지되어야 한다.In general, the flange of the tension roller requires precise dimensional control, that is, flatness, concentricity, etc., and the right angle must be maintained while the flange is inserted into the stud of the tension arm.
그러나 종래에는 제 5 도에서와 같이 스테인레스개를 원판(22)으로 절삭하고 그 원판의 원심에 중심공을 형성하여 가공이 용이한 황동재보스(23)를 코오킹한후 다시 표면을 정밀가공해야 하므로 후렌지(21)의 직각도가 불량해지고 또한 작업공정수의 증가로 인한 생산수율이 극히 낮아 제품의 코스트가 비싼단점이 있었다.However, in the related art, as shown in FIG. 5, since the stainless dog is cut into the disc 22 and a center hole is formed in the centrifugal plate of the disc to caulk the easy-to-machine brass 23, the surface must be precisely processed again. The right angle of the flange 21 was poor, and the production yield was extremely low due to the increase in the number of working processes, and thus the cost of the product was expensive.
본 고안은 따라서 이와 같은 문제점을 해결하기 위하여 스테인레스재 원판을 표면가공한후 원판과 황동재 또는 다른 재질의 T자형보스를 밀착시켜 양부속품 사이에 발생한 공극에 금속접착제를 압력을 가하여 주입하는 간단한 접합방법을 채택함으로써 공정수와 원가절감을 기할수 있는 텐숀로울러의 후렌지를 제공하는 것이다.In order to solve the above problems, the present invention is a simple joining method for injecting a metal adhesive into the pores generated between the two parts by contacting the disk and brass or other T-shaped bosses after the surface is processed. It is to provide tension roller of flange roller which can reduce process water and cost by adopting.
이하 첨부된 도면에 의거 본 고안은 실시예를 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
즉 제 1 도는 통상의 프론트로오딩방식의 VTR에 있어서 테이프로오딩상태를 나타낸 계략설명도로서 비디오카세트(1)의 테이프(2)를 풀베이스에 고정된 가이드포스터가 인출하여 로오딩하면서 해드드럼(3)의 원주에 밀착시킴과 동시에 플베이스의 진행으로 텐숀아암어셈블러의 텐숀로울러(4)가 테이프에 장력을 주게되는 테이프로오딩 상태를 나타낸 것이다.1 is a schematic explanatory diagram showing a tape-loading state in a conventional front-loading VTR. When the guide poster fixed to the full base of the tape 2 of the video cassette 1 is drawn out and loaded, The tensioning roller (4) of the tension arm assembler is tensioned to the tape as it is brought into close contact with the circumference of (3), and the tape base is shown.
제 2 도 및 제 3 도는 본 고안에 의한 텐숀로울러 후렌지의 분해사시도와 사용상태 결합단면도이며 도시된 바와같이 텐숀아암에 고정된 스터드(5)에 스프링(6)과 후렌지(6)가 차례로 삽입되고 이 후렌지(6)의 상면에 상술한 텐숀로울러(4)가 놓여진 상태에서 와샤(7) 및 콘너트(8)로 체결되며 콘너트(8)의 조정에 의해 텐숀로울러(4)의 높이를 조정하여 테이프에 장력을 주게된다.2 and 3 are exploded perspective view of the tension roller flange according to the present invention, and a cross-sectional view of the state of use of the flange. As shown, the spring 6 and the flange 6 are sequentially inserted into the stud 5 fixed to the tension arm. The tension roller 4 is fastened to the washer 7 and the cone nut 8 in the state where the tension roller 4 is placed on the upper surface of the flange 6, and the height of the tension roller 4 is adjusted by adjusting the cone nut 8. Will give tension to the tape.
이와 같은 기술적구성중 주요지는 텐숀로울러용 후렌지(6)의 구조에 있다.The main point of such technical configuration is the structure of the flange 6 for the tension roller.
즉 상술한 바와 같이 원형으로 절삭된 원판(6a)의 원심으로 스터드(5)가 삽입되도록 중심공을 형성하여 정밀 표면처리후 원판저면으로 T자 모양의 황동재보스(6b)의 중공부와 일치시켜 금속접착재로 접합한다.That is, as described above, the center hole is formed so that the stud 5 is inserted by centrifugation of the circularly cut disc 6a, and the surface of the disc is aligned with the hollow portion of the T-shaped brass material boss 6b after the precision surface treatment. Join with a metal adhesive.
제 4 도는 본 고안의 후렌지 접합공정을 나타낸 계략 설명도로서 테이블의 홈에 위치한 지그(9)에 원판(6a)의 중심공을 삽입하고 그위로 돌출된 지그에 T자 모양의 황동재보스(6b)를 올려 놓는다.4 is a schematic explanatory diagram showing the flange joining process of the present invention. The center hole of the disc 6a is inserted into the jig 9 located in the groove of the table, and the T-shaped brass material boss 6b is inserted into the jig protruding thereon. Put it on.
다음에 스프링의 탄성을 받는 테이퍼축(10)으로 압압하면서 원판(6a)과 보스(6a)사이의 공극에 압력을 주면서 금속접착제를 밀어넣게되면 직각도가 양호한 본 고안은 텐숀로울러용 후렌지(6)가 완성되는 것이다.Next, when the metal adhesive is pressed while pressing the gap between the disc 6a and the boss 6a while pressing the tapered shaft 10 receiving the elasticity of the spring, the present invention having a good right angle is the flange for the tension roller. ) Is completed.
이와 같이 본 고안은 간단한 방법으로 부속품을 접합하여 생산수율을 극대화시켜 원가절감과 아울러 동심도 및 직각도가 우수한 저가의 후렌지를 제공하는 장점이 있는 것이다.As such, the present invention has the advantage of providing a low-cost flange that is excellent in concentricity and squareness as well as cost reduction by maximizing the production yield by joining the accessories in a simple way.
