SUMMARY OF THE INVENTION In the above-mentioned conventional parts cleaning apparatus, the cleaning liquid is injected into the cleaning tank to stir the cleaning liquid in the cleaning tank, or the parts in the cleaning liquid are shaken to cause Cleaning the parts. However, in parts with holes and other parts and parts with complicated shapes, it is possible that the cleaning liquid is agitated or the parts are shaken in the cleaning tank so that unnecessary substances such as dust cannot be removed and remain. ,
Further, the cleaning work requires a great deal of labor and time. Further, during the work of cleaning the parts, the cleaning liquid is immediately contaminated and it is necessary to replace the cleaning liquid, which causes a deterioration in workability.

Therefore, there is a technical problem to be solved in order to surely clean the parts and to facilitate the cleaning work. The present invention aims to solve the problems. To do.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed in order to achieve the above-mentioned object, and is a device for cleaning a part for injecting a cleaning liquid into a cleaning tank and cleaning mechanical parts and the like in the cleaning tank. In the cleaning tank, an air outlet is provided, and air can be ejected from the outlet by an air pump, and a centrifugal separator, a filtering device, and a heating device are connected to the cleaning tank to purify the cleaning liquid. At the same time, the invention provides a cleaning device for parts, which is characterized in that the cleaning liquid can be heated.

[0007]

According to the present invention, an air jet is provided in the cleaning tank so that the air can be jetted from the jet by the air pump. Therefore, even if the inside of the component or the component having a complicated shape is used, it is possible to reliably remove the unnecessary substances in every corner by the jet of the air. Further, the cleaning liquid heated by the heating device easily removes unnecessary substances.

Further, since the cleaning liquid is purified by connecting the centrifugal separator and the filtering device to the cleaning tank, the cleaning liquid is prevented from being contaminated and the cleaning liquid does not need to be replaced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. In the figure, reference numeral 10 is a component cleaning device, and a cleaning liquid 12 is poured into a cleaning tank 11. A circulation device 13 is connected to the cleaning tank 11 through pipes 14 and 14. The circulation device 13 sucks the cleaning liquid 12 through a pipe 14 connected to the lower portion of the cleaning tank 11, and the cleaning tank 1 through a pipe 14 connected above the cleaning tank 11.
It is configured to re-inject into 1.

Further, an air pipe 15 is arranged at the lower part of the cleaning tank 11 in the longitudinal center thereof, and an end portion of the air pipe 15 is connected to an air pump 16 outside the cleaning tank 11. is there. Further, an air ejection port 17 is provided at an appropriate position of the air pipe 15, and the air pump 1
When 6 is operated, the air can be jetted upward from the jet port 17. The jet of air is set to about 3 kg / cm ² , but it should not be limited to this. Further, the number, shape, arrangement position, etc. of the jet nozzles 17 can be formed so as to be easily cleaned according to the shape of the parts to be cleaned.

FIG. 2 is a circuit block diagram of the component cleaning apparatus 10. The cleaning liquid 12 in the cleaning tank 11 flows into the overflow tank 18 of the circulation device 13, and the pump 19
Is sent to the cleaning liquid management tank 20. Then, the cleaning liquid management tank 20 reaches the centrifuge 21, where the primary unwanted substances are removed. After that, cleaning solution 1
2 is sent to the second management tank 22. The second management tank 2
2 is equipped with a filtering device 23, and the filtering device 23
Then, the second unnecessary material is removed. Then, the cleaned cleaning liquid 12 is heated by the heating device 24 and is again injected into the cleaning tank 11.

When cleaning the parts, as shown in FIGS. 2 and 3, the parts 25, 25 are set in the cleaning tank 11 into which the cleaning liquid 12 is poured. In the present embodiment, the piston part will be described as an example, but the present invention should not be limited to this. The set includes the long holes 26, 26, 26 of the parts 25, 25.
The long holes 26, 26, 26 and the jet outlets 17, 17, 17 are connected to the lower end of the jet outlets 17, 17, 17 so as to match with each other.

The air pump 16 and the circulation device 13
To operate. At this time, the air jetted from the jet outlets 17, 17, 17 has the long holes 26, 26, 2 of the parts 25, 25.
6 is jetted out into the long hole 2 by the air and the cleaning liquid 12.
Securely remove unnecessary substances such as dust and dirt inside 6, 26 and 26 to the outside. Further, since the cleaning liquid 12 is heated by the heating device 24, the unnecessary substances can be easily removed from the parts 25, 25.

Further, the centrifuge 21 and the filtering device 23 remove unnecessary substances discharged into the cleaning liquid 12 by cleaning the parts 25, 25, and prevent the cleaning liquid 12 from being contaminated.
The parts 25, 25 thus cleaned are now in the NAS 7 class, whereas they were in the NAS 11 class in the past. In addition, the cleaning liquid 12 could be maintained at the NAS 6 grade or lower. Incidentally, the present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified one.

[0015]

As described in detail in the above one embodiment, the present invention provides the cleaning tank with the air ejection port, so that the air is ejected from the ejection port and is not attached to the parts to be cleaned. Objects can be reliably and easily excluded. Also, since the heating device connected to the cleaning tank heats the cleaning liquid,
Further, it facilitates the removal of unnecessary substances and shortens the cleaning time.

Further, since the centrifuge and the filtering device purify the cleaning liquid in the cleaning tank, there is no need to replace the cleaning liquid, and the workability is remarkably improved.
