Description
Technical Field
The utility model relates to a detection device, in particular to a detection device for an automobile oil filter.
Background
The joint of the integral shell and the end cover of the oil filter for the automobile must strictly prevent the leakage of internal high-pressure engine oil. Otherwise, the leaked engine oil not only contaminates the vehicle, but also leaks to the ground and the vehicle slips to cause traffic accidents, causing danger. In the production process of the oil filter, in order to detect whether leakage occurs, the currently adopted method is to charge high-pressure gas into the filter, then immerse the filter in water to observe whether bubbles leak out or not, or test and judge whether the filter leaks by accessing an air tightness test bed. When in detection, the oil outlet hole with the connecting thread in the center of the end cover part of the filter is connected with the connecting inflation inlet of the leakage detection equipment, and compressed gas is fully filled. In order to prevent high-pressure gas from leaking from the joint of the filter and the detection connecting plate, a sealing ring is arranged on all the detection equipment at home and abroad at present, and the sealing ring is just embedded in a large-opening sealing ring groove of the end cover of the filter, so that the part outside the large-opening sealing ring can be detected. However, when the detection is carried out, the sealing ring is just embedded in the groove of the large-opening sealing ring of the end cover of the filter, if the groove of the large-opening sealing ring has cracks, the existing detection method cannot detect the large-opening sealing ring, and the accuracy of a detection result is influenced.
