The nozzle 2 for jetting is exposed. The bottom surface of the cleaning tank 1 may be composed of the concave curved surface 3 and the inclined flat surface 5.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a washer for removing oil, chips, sludge, etc. adhering to a machined object to be washed by water.

[0002]

[Prior art]

 Metal parts such as cutting oil, cutting oil, chips, sludge, etc. adhere to machined metal parts such as cutting, cutting, polishing or drilling, so it is necessary to wash and remove them for the next process. is there. As a cleaning device for that purpose, there is known a cleaning device in which an object to be cleaned is put in a basket of an appropriate size and cleaning water can be sprayed from a nozzle to the cleaning object. Also, the basket is rotated or swung to enhance the cleaning effect.

[0003]

[Problems to be solved by the device]

 However, adding a mechanism for rotating or swinging the basket causes inconveniences such as a high cost and a large size of the entire apparatus, which complicates handling or maintenance. The present invention has been made to solve such problems, and an object thereof is to provide a cleaning device having a simple structure and a high cleaning effect.

[0004]

[Means for Solving the Problems]

 The invention of claim 1 made to solve the above-mentioned problem is that a nozzle for injecting cleaning water from an oblique direction to the concave curved surface is provided above the cleaning tank having a concave curved surface on the bottom surface. It is a feature. According to the invention of claim 2, the cleaning water is sprayed from above the cleaning tank having a concave curved surface and an inclined flat surface with an inclination angle of 15 to 30 ° from an oblique direction with respect to the concave curved surface. It is characterized by having a nozzle. The concave curved surface is preferably a spherical surface or a cylindrical surface.

[0005]

[Embodiment of device]

 Next, a preferred embodiment of the present invention will be described with reference to FIGS. First, in FIG. 1, the cleaning tank 1 accommodates an appropriate number of objects to be cleaned 4 and is made of metal, such as stainless steel, having an outer diameter and a depth such that they can roll, as will be described later. It is a tank made of a material that is difficult to do. The bottom surface thereof is formed into a concave curved surface 3, and a nozzle 2 that jets cleaning water from a direction oblique to the concave curved surface 3 is provided above the concave curved surface 3.

In such a cleaning device, when the cleaning water is sprayed from the nozzle 2, the cleaning water obliquely collides with the concave curved surface 3 at the bottom of the cleaning tank 1 and changes its direction to generate a violent vortex. Then, the object to be cleaned 4 housed in the cleaning tank 1 rolls in the tank due to this vortex flow. In this way, the object to be cleaned 4 rolls while contacting the cleaning water, so that the dirt can be efficiently removed.

In FIG. 2, the bottom portion of the cleaning tank 1 similar to the above is composed of two kinds of surfaces, an inclined flat surface 5 having an inclination angle of 15 to 30 ° and a concave curved surface 3. A nozzle 2 is provided to inject the cleaning water obliquely to the concave curved surface 3. In this case, if the cleaning water is sprayed from the nozzle 2, a violent vortex is generated as in FIG. 1, but the turbulence is disturbed by the slope 5 and the vortex becomes an irregular flow. It is often removed. If the inclination angle is outside the range of 15 to 30 °, the object to be washed is less likely to roll, so it may be selected within this range.

In the above embodiment, the concave curved surface 3 is preferably a spherical surface or a cylindrical surface. Also, the case where the number of nozzles 2 for injecting cleaning water is one has been described, but in addition to the number of nozzles 2, conditions such as nozzle diameter, cleaning water pressure, nozzle position, etc. are appropriately selected and the object to be cleaned is selected. Should be set to the condition that makes it most likely to roll.

[0009]

【Example】

Next, an embodiment of the present invention will be shown. (Example 1) The cleaning tank 1 in this example has the shape shown in FIG. 1, and has an inner diameter of 260 mm, a concave curved surface R of 130 mm, and a depth of 150 mm. Two nozzles having a diameter of 3.5 mm are obliquely attached to the concave curved surface 3 of the cleaning tank 1 near the periphery thereof. The object to be cleaned 4 is a cutting oil or cutting oil machined into a shape (length 20 mm, outer diameter 20 to 14.5 mm, shaft hole diameter 9.5 mm, hole depth 15 mm) shown in FIG. It is a metal part made of aluminum alloy with powder adhering to it. Two parts were washed at a time. When the above-mentioned object to be cleaned was washed with 3 kg / cm ² of pressurized water in such a washing machine for 1 minute, stains could be completely removed. In addition, by appropriately tilting the cleaning tank 1, the rolling state of the object to be cleaned could be adjusted.

Example 2 The cleaning tank 1 in this example has a shape shown in FIG. 2, and a combination of a concave spherical surface with R = 130 mm and an inclined flat surface with an inclination angle of 30 ° is combined at the bottom of the cleaning tank 1. It is a thing. The object to be cleaned 4 is aluminum machined into a shape (length 66 mm, outer diameter 30 mm, shaft hole diameter 15 to 9.5 mm) shown in FIG. These are metal parts made of alloy, and they were cleaned one by one. In this case, the same good results as in Example 1 could be obtained under the washing conditions of pressurized water: 3 kg / cm ² , number of nozzles: 3, and time: 1 minute.

[0011]

[Effect of device]

 The cleaning device of the present invention is configured as described above, and because the object to be cleaned rolls in the cleaning tank due to the violent vortex caused by the cleaning water that obliquely hits the concave curved surface, An excellent cleaning effect can be obtained without the need to rotate the basket containing the object to be cleaned. Moreover, there is an excellent effect that the structure is simple and the maintenance is easy. Therefore, the present invention has an extremely large practical value as a cleaning device that solves the conventional problems.
