BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pollution-free cleaning device for cleaning industrial parts such as electronic parts and mechanical parts, and products by using only high-pressure water.

[0002]

2. Description of the Related Art Conventionally, CFCs, trichloroethane, various organic solvents, alkaline cleaning water, etc. have been frequently used for this type of cleaning. However, these have a great influence on the human body and damage to the human body. Since the treatment is difficult, an apparatus for cleaning by using a jet jet of water has been adopted in recent years. In a cleaning device using this jet jet, cleaning is performed by ejecting a jet of water from a nozzle toward a work.

[0003]

However, in the cleaning device using the jet jet, the part which is hit by the jet is cleaned well, but the part which is hard to hit does not have the cleaning effect. Further, in order to surely perform the cleaning, multi-stage cleaning is required. In this case, since the cleaning units are connected in the lateral direction, there is a problem that the apparatus becomes large.

The present invention has been made in order to solve the above-mentioned conventional problems, and the purpose thereof is to make it possible to apply the jet to the work evenly, uniformly and efficiently. Another object of the present invention is to provide a high-pressure water cleaning device that can be compactly formed even if cleaning units are provided in multiple stages so that even those that are difficult to clean can be properly cleaned.

The cleaning jig is configured to include a cleaning frame that is insertably formed in the mounting portion and a fixing portion that fixes the workpiece to the cleaning frame.

[0011]

In the high-pressure water cleaning device according to the first aspect of the present invention, the endless belt-shaped body of the drive unit is stretched over all the wheels, and the rotating wheel is supported by one horizontal shaft. The resistance when rotating one rotating wheel is smaller than the resistance when rotating one wheel. For this reason, the rotating wheel will rotate when the indexing portion is released,
In this rotation of the rotary wheel, if the rotary wheel is fixed at the indexing part for each pitch of the loading slot, each loading slot will have its loading position,
It is placed in the washing position, draining / drying position.
Then, since the endless belt-shaped body is switched to drive each wheel this time, the mounting portion rotates at each position.

Can be placed in position. It should be noted that at this loading position, unloading and loading can be performed alternately.

At each of the above positions, the work rolls in the cleaning basket due to the rotation of the foil, so that the work can be uniformly cleaned on the entire surface at the cleaning position, and can be dried even at the drying position.

Further, since each work is performed in the vertical plane,
The device is compact and the installation area is small. Further, even if the cleaning units are provided in multiple stages, only the height is increased and the apparatus is not widened.

In the high-pressure water cleaning apparatus according to the second aspect, the two-stage cleaning is performed at the air cleaning position and the underwater cleaning position. First, the jet is jetted directly to the work in the air to remove the deposits. Then, the cavitation effect of the jet injection is effectively utilized in water, and even the portion where the jet flow does not directly hit the surface is uniformly washed by the wraparound effect.

In the high-pressure water cleaning apparatus according to the third aspect of the present invention, in the case of underwater cleaning, the efficiency of the underwater cleaning is improved by confining the energy of the jet in a limited volume and causing convection as strong as possible.

In the high-pressure water cleaning apparatus according to the fourth aspect of the invention, since the nozzle reciprocates at the cleaning position, a jet is jetted over the entire surface of the cleaning basket in addition to rolling of the work without causing a blind spot, and cleaning can be further excellently performed. .

In the high-pressure water cleaning apparatus according to the fifth aspect of the present invention, by rotating the cleaning basket at the jet pressure, the work is subjected to vertical rotation due to rotation of the mounting portion and horizontal rotation due to rotation of the cleaning basket. Since the jet can be applied from all directions of the work, it is possible to effectively and efficiently clean a work having a very complicated shape.

In the high-pressure water cleaning apparatus according to the sixth aspect, for example, a large-scale work or a precision work which does not like contact with another work or impact is not supported by a cleaning jig from a charging port. Put it in and hold it in the mounting part. In this case, since the workpieces are only held and rotated at a fixed position of the cleaning frame at the cleaning position, they do not damage each other,
The entire surface can be washed well.
