The present invention relates to a device for removing water-soluble oil components that separate and float above the oil level of a cutting oil tank in a cutting machine that collects the water.

[Conventional technology]

Fig. 2 shows a general cutting machine (for example, IJ IJ song scene, machining center, etc.).

The workpiece W supported on the work table 11 is a column (tool head) that slides on the machine bed 13.
Predetermined processing is performed by a tool (eg, a drill) 17 supported by 15 . Cutting oil (cooling oil) O is supplied from a cutting oil (cooling oil) supply system 19 to the machining position 10 of the workpiece W through a nozzle 20, while the sliding parts of the machine (e.g.
Lubricating oil ○' is supplied to the sliding surface 21 from a lubricating oil supply system 23. Lubricating oil is stored in a lubricating oil tank 27.

Further, cutting oil is circulated and supplied from a cutting oil tank 29 provided below the machine base. That is, the cutting oil is collected in the cutting oil tank 29, and from there it is passed through the filter 31 again to the pump 35.
It is repeatedly supplied to the processing position 10 by.

Generally, the lubricating oil that has lubricated the lubricating part is also dripped into the cutting oil tank 29 and collected together with the cutting oil.

[Problem to be Solved by the Invention] However, in the above-mentioned cutting machines, water-soluble oil is generally used as the cutting oil, so the lubricating oil is separated in the upper part of the cutting oil in the cutting oil tank. , floating;
Forms a barrier layer with air. As a result, there is a problem in that the cutting oil rots and gives off a strange or foul odor. Also,
There is also the problem that if this cutting oil comes into contact with the hands or skin of a worker, it is likely to cause a rash. Furthermore, this floating layer also made cleaning the cutting oil tank difficult. In the past, the floating separated oil layer was removed manually using a net or a vacuum cleaner.

[Means to solve the problem]

It is an object of the present invention to eliminate the above-mentioned disadvantages, particularly foreign or foul odors, and to protect the workers by removing the lubricating oil layer floating above the cutting oil.

In order to achieve the above object, the present invention includes a cutting oil supply system that supplies cutting oil to a machining position and a lubricating oil supply system that supplies lubricating oil to a lubricating part, In a cutting machine that collects oil together with cutting oil into a cutting oil tank of a cutting oil supply system, a floating component removal device removes a rotating disk with a plurality of grooves formed in the circumferential direction on a part of the plate surface. is rotatably supported in a plane substantially perpendicular to the oil surface so as to be immersed in the oil in the cutting oil tank, and is attached to both sides of the rotating disc outside the cutting oil tank. A structural feature is that a wiping tool is provided to wipe off floating components.

Preferably, the wiping tool is formed by a rubber spatula.

Preferably, the rubber spatula is also angled outwardly and downwardly to cause the wiped floating components to drip onto the outside of the tank.

A music LP or SP record board, or a resin disc can be used as the rotating disc.

[Effect]

The floating layer, that is, the lubricating oil component, adheres to the surface of the rotating disk each time it rotates and immerses in the cutting oil tank. The lubricating oil component adhering to the surface of the rotating disk is scraped off by a wiping tool as the rotating disk rotates.

As a result, the water-soluble cutting oil comes into contact with the air layer, which eliminates problems associated with rotting, such as foul odors, foul odors, and rashes on hands.

〔Example〕

Examples of the present invention will be described in detail below.

According to the present invention, a pair of bearing bodies 53 are supported by columns 55 of a pace 59 placed at the bottom of the cutting oil tank 29.
A rotating shaft 58 rotatably driven by a motor M is rotatably supported. The bearing body 53, the rotating shaft 58, and the motor M are preferably placed above the oil level of the cutting oil tank 29. A rotating disk 57 is rotatably fixed to the rotating shaft 58. The rotating disk 57 rotates in a plane substantially perpendicular to the oil surface. A part of the plate surface of the rotating disk 57, for example, the inside of the lower half, is immersed in cutting oil.

The rotating disk 57 has a large number of minute circumferential grooves 57a formed on its plate surface. These circumferential grooves 57a may be a single spiral groove or a plurality of mutually independent grooves. Further, although the circumferential groove 57a may basically be formed on one plate surface, it is preferably formed on both surfaces. These circumferential grooves 57a are provided to facilitate the attachment of lubricating oil 0' (Fig. 2) floating on water-soluble cutting oil ○. That is, when the rotating disk 57 rotates, when the lower half of the rotating disk 57 immersed in the oil surface emerges from the oil surface, the lubricating oil O'
will be attached together.

In order to check the adhesion of lubricating oil ○° to the rotating disk, various materials (paper, wood, iron, plastic, etc.) were used for the rotating disk.
As a result of experimenting with different materials (wire mesh, etc.), it was confirmed that materials that do not contain moisture and have a uniformly rough surface have a higher adhesion rate. Therefore, it is desirable to use an iron plate or a plastic (resin) plate without surface finishing, and to have circumferential grooves on the micron order formed on both sides of the plate.

Separately, the inventor of the present application focused on an existing music record board (LP or SP) as a rotating disc of the same type, and conducted experiments and obtained very good results. When using such an LP or SP record board, it is extremely useful because an existing new or used record board can be used as is without any processing.

In one embodiment, the lower half of the LP record board is about 45%
When it was immersed in the oil surface and rotated at a speed of 11°5 rotations per minute, the lubricating oil layer floating on the oil surface was able to adhere well.

In order to remove lubricating oil adhering to the rotating disk 57, according to the present invention, both sides of the rotating disk 57 (
In carrying out the invention, a wiping tool 61 is provided on at least one side). In the illustrated embodiment, the wiping tool 61 is formed by a rubber spatula or arm that is pressed against both sides of the rotating disk 57, and wipes off lubricating oil adhering to both sides of the rotating disk 57 as it rotates.

The rubber spatula 61 is fixed to a frame 56 supported by columns 55. Preferably, the rubber spatula 61 is replaceable. In addition, the rubber spatula 61 is tilted downward toward the outside of the tank, and the wiped lubricating oil flows downward along it by gravity, dripping downward from its tip, and the external oil placed below it. The receiver is collected in a container 71.

In addition, when the cutting oil tank is a square container with a cross section of 500 mm x 500 mm, and 501 water-soluble cutting oil is placed inside, and 200 cc of lubricating oil (floating oil) is placed on top of it, 3.
The lubricating oil could be almost completely separated in ~5 minutes.

〔Effect of the invention〕

As described above, according to the present invention, the lubricating oil separated and floating on the oil surface of the cutting oil tank can be removed.
Therefore, the water-soluble cutting oil substantially comes into contact with the air layer, thereby preventing spoilage. Therefore, problems such as rashes that occur when rotten cutting oil comes into contact with the skin or hands are also eliminated.
