本考案は自動車用車輪のリムの溶接部の空気漏
れを容易かつ完全に発見する自動車用リムの空気
漏れ検査機に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air leakage inspection device for automobile rims that easily and completely detects air leakage from welded portions of automobile wheel rims.
従来、自動車用車輪のリムは、第１図イに示す

図ニに示すような所定のリム１に成形する。 Conventionally, the rim of an automobile wheel is made by bending a steel plate 2 into a cylindrical shape as shown in FIG. 1A, as shown in FIG. A cylindrical body 4 is formed as shown, and the welded portion 5 joined by the above-mentioned welding is cut to the same height as the surface of the plate material, and then rolled into a predetermined rim 1 as shown in FIG. Form into.
上記工程を経て成形された自動車用車輪のリム

孔などの欠陥が発生するため、目視検査及び磁気
探傷検査等の検査方法を用いて検査している。し
かし上記方法では十分にかつ完全に検査が出来
ず、又Ｘ線検査等の非破壊検査では時間と費用が
かさみ非常にコストアツプとなる欠点がある。 Since defects such as large cracks, small cracks, hair cracks, and small holes occur in the welded part 5 of the automobile wheel rim formed through the above process, inspection methods such as visual inspection and magnetic flaw detection are used. It is being inspected. However, the above-mentioned method does not allow sufficient and complete inspection, and non-destructive inspection such as X-ray inspection takes time and costs, resulting in a significant increase in cost.
上記のように種々の検査法を用いても、リム溶

はゆるやかな圧力減少となり、高速道路等を走行
していると非常に危険であり、大事故の原因につ
ながる。 Even if various inspection methods are used as described above, if a penetrating crack occurring in the rim weld 5 is not discovered and the tire is assembled with a tire and installed on an automobile, the tubeless tire used in the tubeless tire When tires are used for tires with tubes, water enters through cracks in the welds and gradually corrodes the tubes, causing holes in the tubes and air leaks. let In such a situation, the wheel must be replaced, and the cost and time required for replacement etc. are extremely large. In addition, if the through hole in the weld is large and air leaks rapidly, it can be detected before driving, but if the through hole is small (about a few microns) or the tire has a tube, the air leak will be gradual. The pressure decreases, which is extremely dangerous when driving on expressways, etc., and can lead to major accidents.

じるという欠点がある。 Although improvements have been made to materials, welding methods, machines, etc. to prevent the occurrence of the above-mentioned defects, the current situation is that cracking defects of several percent cannot be avoided. Therefore, methods such as the above-mentioned visual inspection, magnetic flaw detection, or X-ray inspection are used to discover cracks that have occurred, but these methods are not perfect. For this reason, there is a method of sealing the rim welded parts 5 of all products, both good and defective, by applying a thermosetting resin, but this has to be done even for non-defective products that are not actually needed, and it is difficult to do so. The drawback is that the welded area must be cleaned and then heated and painted, making the process complicated and extremely expensive. Furthermore, the paint is difficult to apply to the welded parts coated with resin, which detracts from the appearance of the parts, and the resin peels off during driving, causing air leakage.
本考案は上記欠点を除去し、リムの空気漏れを
