Description
본 발명은, 넥크 측정장치에 관한 것으로서, 보다 상세하게는, 넥크(flareless)의 양 자유단부면의 평탄도를 간편하면서도 정확하게 측정할 수 있도록 한 넥크 측정장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a neck measuring apparatus, and more particularly, to a neck measuring apparatus capable of easily and accurately measuring the flatness of both free end faces of a neck.
일반적으로 음극선관은 전방에 마련되어 화상이 투사되는 패널과, 모일부가 형성되어 있는 깔때기 형상으로 플리트실링에 의해 패널의 후방에 접합되는 펀넬과, 가압융착에 의해 펀넬의 후면 모일부에 접합되는 넥크를 갖는다.Generally, a cathode ray tube is provided in front of the panel on which an image is projected, a funnel shape in which funnels are formed, and a funnel bonded to the rear of the panel by pleat sealing, and a neck bonded to the rear side of the funnel by pressure welding. Has
넥크는, 통상적으로 원기둥형상의 중공관으로 형성된 넥크(flareless)와 중공관의 단부에 확경된 깔때기부를 갖는 넥크(flare)의 2종류로 구분되며, 종래에서는 주로 후자의 넥크(flare)를 사용하여 펀넬의 후면 모일부에 접합시켰으며, 펀넬에 넥크(flare)를 접합시킨 후에는 넥크(flare)의 깔때기부를 소정길이 절단하고 전자총을 삽입시키게 되었다. 그러나, 근자에 들어서는 넥크(flare)를 사용하기보다는 펀넬에 접합된 후에도 별도로 깔때기부를 절단할 필요가 없는 원기둥형상의 중공관으로 형성된 넥크(flareless)를 사용하는 빈도가 높아지고 있는 실정이다.Necks are generally classified into two types: a collar formed of a cylindrical hollow tube and a flare having a funnel portion enlarged at the end of the hollow tube. In the past, the neck is mainly used by using the latter flank. The funnel was bonded to the back side of the rear panel, and after the flare was bonded to the funnel, the funnel of the neck was cut to a predetermined length and an electron gun was inserted. However, the frequency of using the neck (flareless) formed of a cylindrical hollow tube that does not need to cut the funnel separately after being bonded to the funnel rather than using a neck (flare) in the roots is increasing.
그런데, 넥크(flareless)를 사용할 경우에는 깔때기부를 절단할 필요는 없으나, 넥크(flareless)와 펀넬간의 접합면을 양호하게 유지하기 위해서는 넥크(flareless)의 양 자유단부면의 평탄도가 항상 일정한 허용범위 이내로 유지되도록 관리해야만 한다. 따라서, 넥크(flareless)의 양 자유단부면의 평탄도를 간편하면서도 정확하게 측정할 수 있는 별도의 수단이 절실히 요구되고 있다.By the way, when using a neck (flareless) it is not necessary to cut the funnel, but in order to maintain a good joint between the neck (flareless) and the funnel good flatness of both free end face of the neck (flareless) is always constant It must be managed to stay within. Therefore, there is an urgent need for a separate means capable of measuring the flatness of both free end faces of the collar simply and accurately.
따라서, 본 발명의 목적은, 넥크(flareless)의 양 자유단부면의 평탄도를 간편하면서도 정확하게 측정할 수 있도록 한 넥크 측정장치를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a neck measuring apparatus which enables simple and accurate measurement of the flatness of both free end faces of a neck.

넥크홀더(30)는, 넥크(10,flareless)의 내부로 삽입되어 넥크(10,flareless)를 파지하는 원기둥 형상의 홀딩부(32)와, 정반(20)내에 매입된 볼베어링(25)에 삽입되어 정반(20)으로부터 소정길이 노출되는 저널부(44)와, 홀딩부(32)와 저널부(44) 사이에 회전가능하게 배치되는 원반상의 턴테이블(46)을 갖는다.The neck holder 30 is inserted into a cylindrical holding portion 32 inserted into the neck 10 and holding the neck 10 and a ball bearing 25 embedded in the surface plate 20. And a journal portion 44 exposed a predetermined length from the surface plate 20 and a disk-shaped turntable 46 rotatably disposed between the holding portion 32 and the journal portion 44.
또한, 홀딩부(32)의 연부면으로부터 반경방향으로 팽창되어 넥크(10,flare less)의 내벽면에 밀착접촉됨으로써 넥크(10,flareless)를 홀딩부(32)에 밀착고정시키는 다수의 고정부재(34)를 갖는다. 여기서, 고정부재(34)로는 볼 플런저를 사용할 수 있으며, 홀딩부(32)는 넥크(10,flareless)가 회전가능한 턴테이블(46)상에서 유동하지 않도록 위치고정시키는 역할을 하므로, 턴테이블(46)상에 스크루등에 의해 고정될 수도 있고, 턴테이블(46)에 소정의 함몰 그루브를 형성하고 이에 홀딩부(32)를 억지끼워맞춤시킬 수도 있음은 물론이며, 턴테이블(46)과 일체로 형성될 수도 있음을 두말할 여지가 없다.In addition, a plurality of fixing members that expand in the radial direction from the edge of the holding portion 32 to be in close contact with the inner wall surface of the neck (10, flare less) to tightly fix the neck (flareless) to the holding portion 32 Has 34. Here, a ball plunger may be used as the fixing member 34, and the holding part 32 serves to fix the position so that the neck 10 does not flow on the rotatable turntable 46, and thus, on the turntable 46 It may be fixed by a screw or the like, and a predetermined recessed groove may be formed on the turntable 46 and the holding portion 32 may be forcibly fitted thereto, and may be integrally formed with the turntable 46. It goes without saying.
한편, 측정수단(50)은, 홀딩부(32)와 소정거리 이격배치되어 홀딩부(32)와 동축선을 갖도록 정반(20)으로부터 기립배치되는 컬럼(52)과, 컬럼(52)의 상측 단부에 대해 소정 각도범위내에서 회전가능하게 배치되는 회동아암(54)과, 회동아암(54)의 단부에 설치되어 넥크(10,flareless)의 상단면에 접촉됨으로써 넥크(10, flareless)의 단부면 평탄도를 측정하는 측정부재(56)를 포함한다. 여기서, 측정부재(56)로는 다이얼게이지(56)인 것이 바람직하나, 사용자가 사용하기 편리하고 측정값이 정확한 여타의 측정부재를 사용하더라도 관계없음은 물론이다.On the other hand, the measuring means 50 is arranged to be spaced apart from the holding portion 32 by a predetermined distance, the column 52 standing up from the surface plate 20 so as to have a coaxial line with the holding portion 32, and the upper side of the column 52 Rotating arm 54 rotatably disposed within a predetermined angular range with respect to the end, and is provided at the end of the rotating arm 54 to be in contact with the top surface of the neck 10 (flareless) end of the neck 10 (flareless) It includes a measuring member 56 for measuring the flatness. Here, it is preferable that the measuring member 56 is a dial gauge 56, but it is a matter of course that the user can use any other measuring member that is convenient for the user and the measured value is accurate.
이러한 구성에 의해, 도 2를 이용하여 넥크(10,flareless)의 단부면 평탄도를 측정하는 과정을 설명하면 다음과 같다.With this configuration, a process of measuring the end surface flatness of the neck 10 (flareless) will be described with reference to FIG. 2.
먼저, 작업자는 측정하고자 하는 넥크(10,flareless)를 턴테이블(46)상에 배치시킨다.(S1) 이 때, 홀딩부(32)는 넥크(10,flareless)의 내부로 삽입되며, 넥크(10,flareless)가 턴테이블(46)의 상단면에 접촉되었을 때, 홀딩부(32)의 연부면에 마련된 다수의 플런저(34)는 넥크(10,flareless)의 내벽면에 밀착접촉됨으로써 넥크(10,flareless)는 턴테이블(46)상에 위치고정될 수 있게 된다.First, the operator places the neck 10 (flareless) to be measured on the turntable 46 (S1). At this time, the holding part 32 is inserted into the neck 10 (flareless), the neck 10 When the flareless contacts the top surface of the turntable 46, the plurality of plungers 34 provided on the edge surface of the holding part 32 are in close contact with the inner wall surface of the neck 10. flareless can be positioned on the turntable 46.
다음, 컬럼(52)의 상단면에 위치한 회동아암(54)을 소정각도 회전시켜, 즉, 반시계방향으로 회전시켜,(S3) 다이얼게이지(56)의 측정팁(57)이 넥크(10,flare less)의 단부면에 접촉되도록 한다.(S5) 이 때, 다이얼게이지(56)는 제로세팅되어 있어야 한다. 이러한 과정이 모두 완료되면, 턴테이블(46)을 소정의 회전속도로 회전시키면서 넥크(10,flareless)의 단부면 평탄도를 측정하게 된다. 즉, 넥크(10,flare less)가 한바퀴 회전하게 되면 작업자는 다이얼게이지(56)에 나타난 눈금과 소정의 기준눈금과를 비교하여 넥크(10,flareless)의 단부면 평탄도의 양,불량 상태를 파악하게 된다.(S7) 이와 같이 넥크(10,flareless)의 일측 단부면 평탄도의 측정이 완료되면, 타측 단부면의 평탄도 측정을 위해 넥크(10,flareless)를 턴테이블(46)상에서 전복 배치시킨 후, 상기의 공정을 반복하게 된다.Next, the rotating arm 54 located on the top surface of the column 52 is rotated by a predetermined angle, that is, rotated counterclockwise (S3), and the measuring tip 57 of the dial gauge 56 is connected to the neck 10,. (S5) At this time, the dial gauge 56 should be set to zero. When all of these processes are completed, the end surface flatness of the neck 10 is measured while rotating the turntable 46 at a predetermined rotation speed. That is, when the neck 10 rotates one turn, the operator compares the scale displayed on the dial gauge 56 with a predetermined reference scale to determine the amount and defect of the flatness of the end face of the neck 10. (S7) When the flatness of one end surface of the neck 10 is completed as described above, the neck 10 flareless is disposed on the turntable 46 to measure the flatness of the other end surface. After the process, the above steps are repeated.
이와 같이, 본 발명에 따르면, 넥크(10,flareless)의 단부면에 측정부재(56)를 배치시킨 후, 턴테이블(46)을 소정의 회전속도로 회전시키면서 넥크(10,flare less)의 단부면 평탄도를 측정함으로써, 간단하게 구성할 수 있을 뿐만 아니라, 측정작업이 매우 간편하며, 정확한 평탄도의 측정값을 얻을 수 있다는 우수한 효과를 제공할 수 있게 된다.Thus, according to the present invention, after placing the measuring member 56 on the end face of the neck 10 (flareless), the end face of the neck 10 (flare less) while rotating the turntable 46 at a predetermined rotational speed By measuring the flatness, not only can be easily configured, but also the measurement work is very simple and can provide the excellent effect of obtaining the measured value of the correct flatness.
이상 설명한 바와 같이, 본 발명에 따르면, 넥크(flareless)의 양 자유단부면의 평탄도를 간편하면서도 정확하게 측정할 수 있도록 한 넥크 측정장치가 제공된다.As described above, according to the present invention, there is provided a neck measuring apparatus which enables simple and accurate measurement of the flatness of both free end faces of a neck.
