Description

진공펌프의 사점갭 검사장치Dead Point Gap Inspection System of Vacuum Pump

본 발명은 차량용 발전기에 설치되는 진공펌프의 사점(사點)에 형성되는 갭을 용이하고 정확하게 검사하여 상기 진공펌프의 불량여부를 사전에 판별하며 불량품일 경우 이를 설치하기전에 발출하여 정상적인 제품만을 생산할 수 있도록 한 진공펌프의 사점갭 검사장치에 관한 것이다.The present invention can easily and accurately inspect the gap formed in the dead point of the vacuum pump installed in the vehicle generator to determine whether the vacuum pump is defective in advance, and if it is a defective product, only the normal product can be extracted before installation. It relates to a dead point gap inspection device of a vacuum pump.

일반적으로 차량의 전원공급을 위하여 설치되는 발전기(alternator)에는, 중소형 디젤엔진의 차량에서 브레이크의 작동상 작은 힘으로 큰 힘을 얻기 위하여 발전기와 동축상으로 진공펌프를 설치하고 있으며, 이 진공펌프는 진공펌프는 흡기구와 배기구가 설치된 펌프 하우징내에 베인이 설치된 펌프로터를 설치하고 상기 하우징의 내부로 공기를 흡입하며 오일을 공급받아, 공기와 오일을 상기 펌프로터와 베인으로 순환시키면서 진공력을 발생시키도록 되어 있었고 상기 하우징의 일방에 베인과의 갭이 가장 작은 사점과 펌프동작이 이루어지는 부분이 형성되면서 차량에의 진공력을 제공하도록 되어 있었으며 상기 사점의 갭은 통상 1/100mm일 경우에 그 펌프효율이 우수하도록 되어 있다.In general, an alternator installed for power supply of a vehicle is provided with a vacuum pump coaxially with the generator in order to obtain a large force with a small force in brake operation in a vehicle of a small and medium-sized diesel engine. The vacuum pump is provided with a vane pump rotor in the pump housing where the inlet and exhaust ports are installed, and the air is sucked into the housing to receive oil, thereby circulating air and oil to the pump rotor and the vane to generate a vacuum force. It was designed to provide vacuum force to the vehicle by forming the smallest dead spot and pumping part in the gap of vane on one side of the housing, and the pump efficiency when the dead center gap is usually 1/100 mm This is supposed to be excellent.

그러나, 상기 사점의 갭은 진공펌프를 제작하여 조립할 때 그 갭이 설계치 보다 다소 다르게 되고 있으며 따라서, 상기의 갭을 측정하는 것은 제품의 신뢰성을 향상시키는 중요한 요인이 되고 있는바, 종래에는 상기와 같은 사점의 갭을 진공펌프 조립시나 조립이후에 검사할 수 있는 방법이나 장치가 없었기 때문에 상기 사점의 갭을 검사하기 위하여 하나의 샘플을 발취하고 이 샘플의 갭을 측정한 다음 통계치에 의거하여 불량품을 발출하고 있었으며 이에따라 불량품의 신속한 발출은 물론, 확실한 검사가 이루어지지 못하게 되므로써 실 사용할 때 잦은 고장의 유발과 더불어 진공력의 저하로 인한 불량이 발생하게 되는 점 등의 문제점이 있었다.However, the gap of the dead point is slightly different from the design value when the vacuum pump is manufactured and assembled. Therefore, measuring the gap is an important factor for improving the reliability of the product. Since there was no method or device for inspecting the dead point gap during or after assembling the vacuum pump, in order to inspect the gap of the dead point, one sample is taken, the gap of this sample is measured, and the defective part is extracted based on statistics. As a result, the rapid release of defective products, as well as the lack of reliable inspections, caused frequent failures in actual use and defects due to a decrease in vacuum force.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 차량용 발전기에 설치되는 진공펌프의 사점(사點)에 형성되는 갭을 검사할 수 있도록 하되, 상기 진공펌프의 0점 즉, 진공펌프의 중심점과 로터의 회전 중심에 따른 기준점을 설정하고 이 기준점에 대한 상기 사점의 갭을 다이얼 게이지로 측정하여 상기 진공펌프의 불량여부를 판별할 수 있도록 하는 진공펌프의 사점갭 검사장치를 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned problems in the prior art, so that the gap formed at the dead point of the vacuum pump installed in the vehicle generator can be inspected, but the zero point of the vacuum pump, that is, the vacuum pump To provide a dead point gap inspection device of a vacuum pump to set the reference point according to the center of rotation and the center of rotation of the rotor and to determine whether the vacuum pump is defective by measuring the gap of the dead point to the reference point with a dial gauge. Inba, it will be described in detail based on the accompanying drawings as follows.
