New description: [New technical field] The present invention relates to a detecting device, in particular to an oil seal detecting device. [Prior Art] The oil seal is mainly installed on the cavity bearing and gear box of the boring machine. In order to prevent oil leakage inside the cavity, it is suitable for various purposes according to the pressure required for assembly, the number of revolutions, etc. Oil seal. Referring to Figure 1 and Figure 2, the conventional oil seal is a hollow ring, comprising a hard: material outer ring 11, - an inner ring 12 surrounded by a soft material and connected to the inner side of the outer ring 11, and At the inner edge of the inner ring 12, one of the main seals of the first seal is disposed on the shaft 21 of a cavity 2, and the shaft ～21 is placed against the main seal lip 13 The ring u is placed against the inner side surface of the cavity 2 to form a tight state. The main sealing lip 13 and the outer ring u prevent oil leakage inside the cavity 2. This conventional oil seal i has been used by the industry for a long time. Inheritance, however, if there is a defect in the surface of the main sealing lip 13 or the outer edge of the outer ring, the oil is easily leaked out through the defect, and when the sealing is used, It is not easy to prevent the oil leakage inside the cavity 2, and the machine is easily damaged. / Therefore, in order to improve the quality of the oil seal 1, the manufacturer will detect the oil seal i to observe the absence of the defect, and the general detection method is to use the general CCD lens to enlarge the oil seal 1 image 50 times, and then observe the oil seal! U ΑΑ main JrJL ^ clothing 12 ring 12 ring; 1 and outer ring 11 outer edge, in this way to detect the defects formed on the inside. However, this method does not easily observe the defect of the 5-M287431 oil seal 1 and the position at which the defect is formed, thereby greatly reducing the detection efficiency and relatively increasing the cost of manual inspection. [New content] Therefore, the object of the present invention is to provide an oil seal detecting device capable of quickly checking the position of a seal defect. Thus, the novel oil seal detecting device is suitable for detecting a defect of an annular oil seal, and the oil seal detecting device comprises: a detecting member and a light source. The detecting member has a light transmitting body and a non-light transmitting body disposed on one side of the light transmitting body and having a sectional area smaller than a sectional area of the light transmitting body. The light source is spaced apart from the other side of the light transmissive body. The oil seal is disposed on the periphery of the non-transmissive body such that the periphery of the non-transmissive body and the inner side surface of the oil-repellent seal are in contact with each other, and the outer periphery of the oil seal is just aligned with the surface of the light-transmitting body, when the inner side of the oil seal is When there is a defect on the outer side, the light source penetrates through the transparent body and forms a light transmitting point, so that the effect of quickly detecting the oil seal defect can be achieved. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figure 3, a preferred embodiment of the novel oil seal detecting device 3 is adapted to detect a defect 41 of an annular oil seal 4. The preferred embodiment includes a detecting member 31 and a light source 32. The detecting member 31 has a light-transmitting body 311 and a non-transmissive body 312 disposed on one side of the light-transmitting body 3, J, and the cross-sectional area of the non-light-transmitting body 312 is -M287431 is smaller than the light-transmitting body The cross-sectional area of the body 311. The light source 32 is spaced apart from the other side of the light-transmitting body 3, and the light source 32 is not limited to any aspect, and only the light source 32 can generate light to penetrate the light-transmitting body 311 and be The light transmitting body 312 is blocked and can be applied to the present embodiment. When the user wants to detect whether the oil seal 4 has a defect 41, the oil seal 4 is sleeved on the periphery of the non-light-transmitting body 312, so that the periphery of the non-light-transmitting body 312 and the inner side surface of the oil seal 4 are in contact with each other, and The outer periphery of the oil seal 4 is just flush with the surface of the light-transmitting body 3 11 . Referring to FIG. 4, when the inner side surface and the outer side surface of the oil seal 4 have defects 41, the light source 32 penetrates through the light-transmitting body 311 from the defects 41 and forms a light-transmitting point. By the obvious contrast relationship between the light-transmitting point and the non-transmissive body 312, the user can quickly observe whether the oil seal 4 has the defect 41 and the position where the defect 41 is formed, thereby achieving rapid detection. The effect of the defect 41 of the oil seal 4. _ In summary, the new oil seal detecting device 3 uses the light source 32 to generate light to penetrate the light-transmitting body 311, so that the oil seal 4 sleeved on the periphery of the non-light-transmitting body 312 is inside or outside the δ-Hai oil seal 4 The defect 41 can be penetrated by the light emitted by the light source 32 to form a light-transmitting point. By the obvious contrast relationship between the light-transmitting point and the non-transmissive body 312, the user can quickly observe whether the oil seal 4 exists. The defect 41 and the position where the defect 41 is formed can surely achieve the defect 41 of the oil seal 4, improve the detection efficiency, and reduce the cost of manual inspection, so that the effect of the present invention can be achieved. However, the above is only a preferred embodiment of the present invention, and does not limit the scope of the present invention when it is not M287431, that is, the simple equivalent change of the scope of the patent application and the new description of the present invention. And modifications are still within the scope of this new patent.
