상기 베이스(10)에 형성된 관통공(14)을 통하여 다이얼 게이지 지지바(71)(72)(73)의 길이를 조절할 수 있는 길이 조절용 볼트(81)(82)(83)가 구비된 작동 샤프트(90)가 상하 작동하는데, 상기 작동 샤프트(90) 하부에는 브레이크 드럼(40)과 허브(50) 측정시 관통공(14) 상단에 형성된 안착홈(12)에 작동 샤프트(90)가 안착되어 정밀한 측정이 가능하도록 상기 안착홈(12)에 안착되는 안착면(92)이 형성된다.Operation shaft provided with length adjusting bolts 81, 82, 83 for adjusting the length of the dial gauge support bars 71, 72, 73 through the through holes 14 formed in the base 10. 90 is operated up and down, the operating shaft 90 is mounted to the mounting groove 12 formed on the upper end of the through hole 14 when the brake drum 40 and the hub 50 are measured below the operating shaft 90. A seating surface 92 seated in the seating groove 12 is formed to enable precise measurement.
특히, 상기 작동 샤프트(90)의 안착면(92) 하부에는 베이스(10)의 관통공(14) 일단에 형성된 안내핀(16)과의 접촉에 따라, 상기 작동 샤프트(90)가 상/하 작동하고 측정물 교체시 상승함에 따라, 상기 작동 샤프트(90)가 90°회동 가능하도록 비틀려서 경사진 경사홈(94)이 형성된다.In particular, the operating shaft 90 is in the upper / lower portion in contact with the guide pin 16 formed at one end of the through hole 14 of the base 10 in the lower portion of the seating surface 92 of the operating shaft 90. As it operates and ascends upon replacement of the workpiece, the inclined groove 94 is formed by twisting the actuating shaft 90 to be rotatable 90 °.
또한, 베이스(10) 하단에는 상기 작동 샤프트(90)를 관통공(14)을 따라 상/하 작동시키며 회동시킬 수 있도록 에어탱크(99)와 연결되며 상기 작동 샤프트(90) 하단에 나사 결합되어 상/하 작동되는 작동바(96) 구비한 작동부(98)가 장착된다.In addition, the bottom of the base 10 is connected to the air tank 99 to rotate the operating shaft 90 up / down along the through hole 14 and screwed to the lower end of the operating shaft 90 An operating part 98 having an operating bar 96 that is operated up / down is mounted.
상기 작동바(96)는 에어탱크(99)로부터 에어 유입시에는 상승하여 작동 샤프트(90)를 상승시킨다.The operation bar 96 rises when air is introduced from the air tank 99 to raise the operation shaft 90.
특히, 상기 작동 샤프트(90)의 하단과 작동바(96)의 상단은 나사 결합되어 상기 작동바(96)가 상승시에 작동 샤프트(90)도 상승하다가 작동 샤프트(90) 하부에 형성된 경사홈(94)이 안내핀(16)에 의해 안내되어 작동 샤프트(90)가 회동되면, 상기 작동 샤프트(90)는 작동바(96)와 나사작용에 의해 회동될 수 있는 것이다.In particular, the lower end of the operation shaft 90 and the upper end of the operation bar 96 is screwed so that the operation shaft 90 also rises when the operation bar 96 is raised, and the inclined groove formed under the operation shaft 90 ( 94 is guided by the guide pin 16 so that the operating shaft 90 is rotated, the operating shaft 90 can be rotated by the screw action with the operating bar (96).
이하, 본 발명에 따른 작용 상태를 설명하면 다음과 같다.Hereinafter, the operation state according to the present invention will be described.
지그에 장착된 브레이크 드럼(40)과 허브(50)의 진원도 및 평면도 등의 정밀도 측정시에 작업자는 길이 조절용 볼트(81)(82)(83)를 조절하여 직경이 다른 브레이크 드럼(40)과 허브(50)에 알맞도록 다이얼 게이지 지지바(71)(72)(73)의 길이를 조절할 수 있다.When measuring the precision of roundness and flatness of the brake drum 40 and the hub 50 mounted on the jig, the operator adjusts the length adjusting bolts 81, 82, 83 and the brake drum 40 having different diameters. The length of the dial gauge support bars 71, 72, 73 can be adjusted to suit the hub 50.
특히, 제 1 다이얼 게이지(61)는 허브(50)의 내경에 대한 정밀도를, 제 2 및 3 다이얼 게이지(62)(63)는 브레이크 드럼(40)의 외경에 대한 정밀도를 측정할 수 있는 것이다.In particular, the first dial gauge 61 can measure the precision of the inner diameter of the hub 50, and the second and third dial gauges 62 and 63 can measure the precision of the outer diameter of the brake drum 40. .
또한, 다이얼 게이지 지지바(71)(72)(73)가 체결된 작동 샤프트(90)의 하부에 형성된 안착면(92)은 베이스(10)에 형성된 안착홈(12)에 안착/고정되어 정밀한 측정이 가능한 것이다.In addition, the seating surface 92 formed on the lower portion of the operating shaft 90 to which the dial gauge support bars 71, 72, and 73 are fastened is seated / fixed in the seating groove 12 formed in the base 10 to be precise. Measurement is possible.
한편, 측정물을 교체시에는 베이스(10) 하단에 장착된 작동부(98)를 작동하면 에어탱크(99)로부터 에어가 유입되어 상기 작동 샤프트(90) 하단에 나사 결합된 작동바(96)는 상승하게 된다.On the other hand, when replacing the workpiece when operating the operating unit 98 mounted on the bottom of the base 10, the air flows from the air tank 99 to the operating bar (96) screwed to the lower end of the operating shaft (90) Will rise.
이에 따라, 작동 샤프트(90)은 베이스(10)의 관통공(14) 일측에 형성된 안내핀(12)과 상기 작동 샤프트(90) 하부에 형성된 경사홈(94)의 안내에 따라 상승하다가, 비틀려진 경사홈(94) 부위와 안내핀(16)이 접촉되는 순간부터 상기 작동 샤프트(90)는 작동바(96)와의 나사작용에 의한 회동된다.Accordingly, the operation shaft 90 rises according to the guide pin 12 formed at one side of the through hole 14 of the base 10 and the inclined groove 94 formed at the lower portion of the operation shaft 90. From the moment when the inclined groove 94 portion and the guide pin 16 come into contact with each other, the operation shaft 90 is rotated by a screw action with the operation bar 96.
특히, 상기 작동 샤프트(90)는 90°까지 회동될 수 있도록 경사홈(94)이 형성된다.In particular, the working shaft 90 is formed with an inclined groove 94 so that it can be rotated up to 90 °.
따라서, 측정물 교체시 일단 작동 샤프트(90)는 상승 후 안내핀(16)이 비틀려진 경사홈(94)과 접촉되는 순간부터 회동되므로 허브(50)의 내경 측정용 제 1 다이얼 게이지(61)는 허브(50) 상단의 간섭을 받지 않고 상승한 후에 회동되는 것이다.Therefore, when the workpiece is replaced, once the operating shaft 90 is rotated from the moment when the guide pin 16 comes into contact with the twisted inclined groove 94 after being raised, the first dial gauge 61 for measuring the inner diameter of the hub 50 is provided. Is rotated after ascending without interference at the top of the hub 50.
이상에서 서술한 바와 같이, 본 발명에 따른 브레이크 드럼과 허브의 정밀도 측정장치에 의하면 다수의 다이얼 게이지가 일체로 조립되며 상/하 작동에 의해 회동되는 측정장치를 지그에 장착하여 브레이크 드럼과 허브의 진원도 및 평편도 등의 정밀도를 정확하게 측정하고 측정물의 교환을 용이하게 할 수 있는 효과가 있다.As described above, according to the precision measuring device of the brake drum and the hub according to the present invention, a plurality of dial gauges are integrally assembled and a measuring device which is rotated by up / down operation is mounted on a jig, There is an effect that can accurately measure the precision, such as roundness and flatness, and to facilitate the exchange of the workpiece.
