Description of the Related Art A cleaning technique has recently been developed for a complicated structure in a laminated state of parts having pores such as blind holes and through holes and plate-like metal parts. Among them, in Japanese Patent Laid-Open No. 3-127672, a cleaning liquid and pressurized air are jetted to a component being conveyed, and the component is stopped,
It is described that at this stop position, a cleaning liquid is jetted to perform cleaning in accordance with the part to be cleaned. As a result, cleaning is performed corresponding to different screw hole positions, sizes, and shapes.

The methods disclosed in Japanese Patent Laid-Open No. 2 and Japanese Patent Laid-Open No. 4-48975 both spray a cleaning liquid from a nozzle and align the nozzle with holes and irregularities of parts. It is the same as spraying a shower. Such shower spraying in air gives a large jet pressure to the shower in liquid, but
There is a drawback that the portion to be cleaned becomes non-uniform depending on how the nozzle is set.

れる洗浄では不利となる。Further, when spraying with a liquid having a high foaming property such as a surfactant, there is a problem in working that bubbles leak out of the cleaning tank. On the other hand, when a non-aqueous organic solvent or the like is used as the cleaning liquid, there is a problem that the liquid is scattered into the working environment, which adversely affects the human body, and the liquid is consumed due to the scattering of the expensive liquid. Because of this, the cleaning tank can be sealed,
It is necessary to accurately control the liquid temperature and wear protective equipment, which complicates the work. Further, since the cleaning liquid is jetted out into the air, the heating effect of the cleaning liquid is small when the object to be cleaned has a large volume and the like, which is disadvantageous in cleaning in which the temperature greatly depends on the cleaning property.

し、工程が煩雑になる。In Japanese Patent Laid-Open No. 4-215880, cleaning is performed by turbulent stirring of insoluble particles in a liquid. Like the shower in the liquid, this method performs cleaning by the relative liquid flow between the surface of the object to be cleaned and the cleaning liquid, but since it only forms a turbulent flow of the entire liquid in the tank, There is a problem that the directionality of the flow is lacking, and the cleaning property for each surface of the cleaning target is low. Further, when finishing quality is highly required, another step is required for removing the used insoluble particles, which complicates the step.

微細孔中の汚れの洗浄時間を飛躍的に短縮できる。According to the present invention, when cleaning a part having a complex structure having pores and irregularities, the part to be cleaned is immersed in a cleaning liquid from a nozzle provided in a cleaning tank. The ultrasonic wave is oscillated by the ultrasonic wave generation means as well as generating a jet flow toward. That is, the directionality is imparted to the nozzles disposed in the liquid to eject the liquid, and the ejection is performed at a high pressure of 5 to 20 kg / cm 2 . By performing such high-pressure jetting, the liquid is vigorously agitated, and this agitation can promote the cleaning of the liquid and the diffusion of the dirt in the area near the dirt on the surface of the object to be cleaned. In this case, the penetration of the cleaning liquid into the micropores having a diameter of about 2 mm or less is impossible only by the osmotic force,
In the present invention, this permeation is assisted by a high-pressure liquid flow.
Furthermore, since ultrasonic waves act on the cleaning liquid, diffusion of dirt and emulsions in the pores and penetration of the cleaning liquid into the pores are promoted by a synergistic effect with the high pressure flow. By this,
The cleaning time for dirt in fine holes can be dramatically reduced.

できる。Since the present invention does not positively move the object to be cleaned, it is advantageous for cleaning the object to be cleaned in which scratches or the like are a problem. Here, in the rotary cleaning using the barrel, the objects to be cleaned collide with each other. This is because it is difficult to fix the object to be cleaned in the rotary cleaning. On the other hand, in jet cleaning, the objects to be cleaned are less likely to collide with each other even when the objects to be cleaned are not fixed, and the objects to be cleaned themselves can be easily fixed. Therefore, in the present invention, it is possible to minimize the occurrence of scratches on the object to be cleaned.

できる。In the present invention, since the high-pressure liquid flow is brought into contact with the surface of the object to be cleaned, not only the above-described cleaning effect by the liquid flow but also random operation such as rotation of the object to be cleaned by the liquid flow is incidentally performed. Can be made. Further, by selecting the outflow pressure and the nozzle position, it is possible to select the desired movement of the object to be cleaned. Therefore, it is possible to perform the same cleaning as using this without using a rotating jig.
【００１２】傷等があまり問題視されない被洗浄物の場

品質の向上及び洗浄時間の短縮が可能となる。In the case of an object to be cleaned in which scratches and the like are not a serious problem, a rotation jig can be used to positively add rotation to the object to be cleaned, thereby improving cleaning quality. Also, the cleaning time can be shortened.

留する油を確実に除去できる。In the case of cleaning an object to be cleaned having a blind hole, when a water-based cleaning agent such as a surfactant is used as a cleaning liquid, the blind hole located on the lower surface of the object to be cleaned due to a difference in specific gravity of cutting oil as dirt. It is difficult to remove the oil inside. On the other hand, when a non-aqueous cleaning agent such as an organic solvent is used as the cleaning liquid, on the contrary, it is difficult to remove the oil in the blind hole located on the upper surface of the cleaning target. The present invention can perform a violent liquid flow or a relative liquid flow between the cleaning liquid and the cleaning liquid due to the violent movement of the cleaning liquid, and thus can reliably remove the oil remaining at the above-mentioned portion.
