Description

부시유닛 검사장치{TESTING APPARATUS OF BUSH UNIT}[0001] TESTING APPARATUS OF BUSH UNIT [0002]

본 발명은 현가장치에 구비되는 로워 암 혹은 어퍼암에 장착되는 부시유닛의 외경 정밀도 및 중철이 내장설치되어 있는지의 여부의 확인을 위한 부시유닛 검사장치에 관한 것이다.      The present invention relates to a bush unit inspecting apparatus for checking the accuracy of the outer diameter of a bush unit mounted on a lower arm or an upper arm provided in a suspension, and for checking whether or not a saddle stitch is installed.

일반적으로, 차량에 있어서 승차감 및 주행안정성을 도모하기 위한 현가장치는 주로 차체를 차륜으로부터 안정적으로 지지하면서 차륜으로부터 제공되는 진동을 억제하거나 또는 신속하게 감소시키는 기능으로서, 이러한 현가장치에는 차륜을 차체에 연결하고 지지하는 기능을 수행하는 로워 암 혹은 어퍼 암이 사용되며, 상기 로워 암에는 주행 중 타이어를 통해 들어오는 횡력, 전후력, 및 상하력을 지지하여 그 충격력을 흡수하는 부시유닛이 장착되어 불규칙한 노면으로부터 발생하는 진동과 충격을 완화시켜 차량의 승차감 및 조종 안정성에 중요한 역할을 하게 된다.      Generally, a suspension device for improving ride comfort and running stability in a vehicle mainly functions to suppress or rapidly reduce the vibration provided from the wheel while stably supporting the vehicle body from the wheel. In such a suspension device, And the lower arm is provided with a bush unit for supporting the lateral force, the forward / rearward force, and the up / down force that are received through the tire during traveling and absorbing the impact force, And it plays an important role in ride comfort and steering stability of the vehicle.

이와 같은 부시유닛은 내측파이프의 외측으로 외측파이프가 구비되고 상기 내측 외측파이프의 사이에는 방진을 위한 충진재와 함께 중철이 구비된다.      In such a bush unit, an outer pipe is provided on the outer side of the inner pipe, and a middle cylinder is provided between the inner outer pipe and the filler for vibration proofing.

위의 구성으로 완성된 부시유닛은 외측파이프의 직경이 클 경우 로워 암 등의 체결부와 결합되지 못하고 불량이 됨에 따라 계측기에 의한 검사가 필요하게 되고, 내부의 중철이 제 위치에 제대로 내장되었는지 여부검사가 필수적이다.When the diameter of the outer pipe is large, the finished bush unit can not be joined with the fastening part of the lower arm or the like and becomes defective. Therefore, it is necessary to inspect the bush unit by the measuring instrument. Inspection is essential.

그러나 위와 같은 검사를 위한 종래의 방식은 별도의 장비가 없어 계측기에 의해서 외경을 검사하고, 중철의 유무를 확인하기 위해서는 송곳 등으로 찔러서 확인하게 되는데 이는 정확성이 떨어지고 복잡다단하여 인력소모와 생산성이 크게 저하되는 문제점이 있다.
However, in the conventional method for the above-mentioned inspection, there is no separate equipment, and the outer diameter is inspected by the measuring instrument. In order to check the existence of the saddle stitching, it is confirmed by stabbing with an auger, There is a problem of deterioration.

본 발명의 목적은 완성된 부시유닛에 있어서, 내부에 장착되는 중철의 유무검사를 장비 없이 수작업에 의해 확인해야하는 불편함과 부정확성을 개선하기 위한 부시유닛 검사장치를 제공함에 있다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a bush unit inspecting apparatus for improving the inconvenience and inaccuracies of a completed bush unit by manually checking the presence or absence of a saddle stitch installed therein.

내측 파이프와 외측 파이프가 구비되고 그 내부에 중철이 장착되는 부시유닛의 검사를 위한 부시유닛 검사장치는, 테이블 위에 하나 이상의 조립판(32)이 구비되고, 상기 각 조립판(32)에는 중앙에 수직으로 샤프트(26)가 설치되고 그 외측으로 부시유닛의 중철(16)과 동일한 위치를 따라 일정한 간격을 두고 배치되는 감지봉체(24)가 내장된 중철검사구(22)가 구비된다.      A bush unit inspecting apparatus for inspecting a bush unit in which an inner pipe and an outer pipe are installed and in which a saddle stitch is mounted is provided with at least one assembly plate (32) on a table, and each of the assembly plates (32) There is provided a saddle stitch inspection tool 22 in which a shaft 26 is installed vertically and a detection stick 24 is disposed outside the saddle 24 at the same position as the saddle stitch 16 of the bush unit.

또한, 상기 중철검사구(22) 위에는 부시유닛의 지정된 최대 외경의 치수를 통과시킬 수 있는 내측면(28a)을 가진 외경검사링(28)이 구비된다. On the saddle stitch inspection tool 22, an outer diameter inspection ring 28 having an inner surface 28a capable of passing the specified maximum outer diameter of the bush unit is provided.

위를 더욱 상세하게 설명하기 위한 도 1은, 부시유닛(10)을 검사장치에 장착하는 상태를 예시한 사시도이고, 도 2는 두개의 측정구에서 하나의 측정구 단면을 보인 상태의 정면을 도시하고 있으며, 도 3은 본 발명 전체의 구성을 도시한 평면도이다. 1 is a perspective view illustrating a state in which the bush unit 10 is mounted on an inspection apparatus, and FIG. 2 is a front view of a state in which one measuring mouth section is shown in two measurement ports, And Fig. 3 is a plan view showing the entire configuration of the present invention.

위의 도면에 의하면 먼저, 본 발명 부시유닛 검사장치에 의해서 검사를 위한 부시유닛(10)은 주로 자동차의 현가장치에 사용되는 로워 암의 일측으로 장작되는 것으로서, 그 구성은 내측 파이프(12)와 외측 파이프(14)가 구비되고 그 내부에 중철(16)과 함께 완충소재의 충진재(18)가 내삽된다.According to the above drawing, the bush unit 10 for inspection by the bush unit inspection apparatus of the present invention is firstly mounted on one side of a lower arm used for suspension of an automobile. An outer pipe 14 is provided and a filling material 18 of a buffer material is inserted into the inner pipe 14 together with the saddle stitch 16.

그리고 상기 부시유닛(10)의 외측파이프 외경 및 중철의 유무상태를 확인하기 위한 부시유닛 검사장치의 구성은 아래와 같다. The configuration of the bush unit inspection apparatus for checking the outer diameter of the outer pipe of the bush unit 10 and the presence or absence of the saddle stitch is as follows.

먼저, 적당한 받침대(34)와 다리(36)에 의해 평면으로 된 테이블(30)이 구비되고 그 위에는 하나 이상의 조립판(32)이 구비된다. 상기 조립판(32)은 후술하는 측정구(20)를 테이블(30)에 장착하기 위한 것으로 조립판 없이도 상기 측정구를 설치할 수도 있다.First of all, a table 30 is provided by a suitable pedestal 34 and a leg 36, and at least one assembly plate 32 is provided thereon. The assembly plate 32 is for mounting a measurement port 20 to be described later on the table 30, and the measurement port may be provided without an assembly plate.

다음, 상기 테이블(30) 위로는 하나 이상의 측정구(20)가 설치되는데 상기 측정구(20)는 수직상으로 외경검사링(28)과 중철검사구(22)가 구비된다.Next, at least one measurement port 20 is installed on the table 30, and the measurement port 20 is provided with an outer diameter inspection ring 28 and a sliver inspecting port 22 in a vertical plane.

상기 중철검사구(22)는 테이블(30) 위에 장착되며 중앙에 수직으로 샤프트(26)가 설치되고, 상기 샤프트를 중심으로 부시유닛의 중철(16)과 동일한 위치를 따라 일정한 간격을 두고 5~8개의 감지봉체(24)가 내장 설치된다. 이때 상기 감지봉체(24)는 자력에 의해 금속으로 된 중철을 감지하여 컨트롤박스(40)에 신호를 전달한다.The sphygmomanometer inspection tool 22 is mounted on a table 30 and is provided with a shaft 26 vertically at the center thereof. The shaft 26 is spaced apart from the sphygmomanometer 16 by a predetermined distance, Eight detecting rods 24 are installed therein. At this time, the sensing rod 24 senses a metal saddle by a magnetic force and transmits a signal to the control box 40.

상기 컨트롤박스(40)는 단자(42)와 커넥터(46) 그리고 소정의 전선(44,45)에 의해 감지봉체와 연결되어 있고 상기 컨트롤박스(40)에는 음향과 시각적으로서 신호상태를 인지할 수 있도록 소정의 스피커 내지는 램프 등을 구비한다.The control box 40 is connected to the sensing rod by a terminal 42 and a connector 46 and predetermined wires 44 and 45 so that the control box 40 can recognize a signal state visually A predetermined speaker, a lamp, or the like.

다음, 상기 중철검사구(22)의 상부에는 샤프트(26)의 동일 축상으로 구멍(28b)을 가지면서 내측면(28a)을 형성하는 외경검사링(28)이 장착된다. Next, on the upper portion of the saddle stitch inspection tool 22, an outer diameter inspection ring 28 which forms an inner side surface 28a with a hole 28b on the same axis of the shaft 26 is mounted.

상기 외경검사링(28)은 내측면(28a)의 직경이 전술한 부시유닛(10)의 외경의 오차범위내에 속하게 되어 검사되는 것으로 즉, 외경검사링의 구멍(28b)으로 제작된 부시유닛의 외측파이프(14)가 삽입되지 않거나 너무 헐겁게 삽입되면 치수불량이 되는 것이다.The diameter of the inner diameter 28a of the outer diameter checking ring 28 is within the error range of the outer diameter of the bush unit 10 as described above, If the outer pipe 14 is not inserted or inserted too loosely, the size becomes defective.

이와 같은 본 발명 부시유닛 검사장치는 제작된 부시유닛(10)을 측정구 상부로부터 구멍(28b)으로 끼워넣게 되면서 부시유닛의 외경파이프의 직경의 불량상태를 확인할 수 있게 됨과 동시에, 외경검사링에 끼워진 부시유닛(10)은 중철검사구(22)의 감지봉체(24)와 접촉하게 되면서 금속소재의 중철(16)이 감지봉체(24)의자성에 자력을 가하게 되면서 컨트롤박스로(40) 신호를 전달한다.In the bush unit inspection apparatus of the present invention, the manufactured bush unit 10 is inserted into the hole 28b from the upper portion of the measurement port, so that it is possible to check the bad condition of the diameter of the outer diameter pipe of the bush unit, The squeezed bush unit 10 is brought into contact with the sensing rod 24 of the saddle stitch inspection tool 22 and a signal is sent to the control box 40 while the saddle metal 16 of the metallic material applies magnetic force to the stiffness of the sensing rod 24 .

이와 같은 신호를 전달받은 컨트롤박스에는 점멸하는 램프 혹은 스피커에 의해 신호음을 발산하게 되면서 부시유닛내부에 중철이 삽입되어 있는지의 여부를 확인할 수 있게 된다.
The control box that receives this signal emits a beep by a flashing lamp or a speaker to check whether or not a saddle stitch is inserted inside the bush unit.
