[Detailed description of the invention]

[0001]

The present invention relates to a cutting oil filtering device for removing chips from cutting oil flowing out of a cutting machine together with chips from a cutting machine, which is separated on a filter net arranged substantially horizontally above a cutting oil tank. The present invention relates to a configuration of an apparatus for removing swarf that has been removed.

[0002]

2. Description of the Related Art In a cutting oil filtration device which has been generally used in the past, in a cutting oil filtration device in which a filter net is disposed substantially horizontally above a cutting oil tank, cutting chips separated and accumulated on the filter net are allowed to stand. Because of the clogging of the filter net by the chips, the cutting oil flowing out of the cutting machine and flowing down on the filter net is prevented from flowing down into the cutting oil tank, and the cutting oil overflows outside the cutting oil tank. Effort must be taken to eliminate chips on the filter net.

[0003] As a countermeasure, a rotary cylinder having a filter net is arranged obliquely on a cutting oil tank, and chips separated from cutting oil in the rotary cylinder are rotated by the rotation of the rotary cylinder. Japanese Unexamined Utility Model Publication No. 64-4540 discloses a cutting oil filtering device configured to move along a spiral guide blade formed on an inner surface of a body and to be discharged from an open end of a rotary cylinder. In this configuration, since the cutting oil flows from the lower end face opening of the rotary cylinder body that is inclined, the longitudinal direction of the device is arranged at right angles to the longitudinal direction of the cutting machine, In addition, the equipment itself is large and requires more space than the above-mentioned cutting oil filtration equipment that is generally used, and if it is going to be introduced to many cutting machines, the layout of the factory will be completely changed. Not only requires Even when the rotation is not being performed, the rotary cylinder continues to rotate and wastes power, and in order to prevent clogging of the filter net of the rotary cylinder, the compressed air is continuously blown to the filter net, and the air in the factory air line is blown. There is a problem that wastes.

[0004]

Therefore, the chips separated on the filter net of the cutting oil filter device having the filter net arranged substantially horizontally above the cutting oil tank are automatically removed from the filter net. ,
It is another object of the present invention to provide a chip removing device in which the operation of removing chips is performed only when the cutting machine is operating and does not consume wasteful energy.

[0005]

The object of the present invention has been solved by the following constitution. That is, a first air cylinder device in which a first operating rod moves forward and backward in a first cylinder in parallel with the filter net is disposed above the filter net, and a second air cylinder device is provided at a tip of the first operating rod. The second cylinder of the second air cylinder device in which the operating rod moves up and down in the second cylinder substantially vertically is fixed, and the lower end of the second operating rod is provided with the first operating rod. A brush for wiping the chips on the filter net by moving forward and backward is fixed, and the second operating rod is positioned above the lower end at a position where the forward and backward movement of the second operating rod is not hindered. First
A chip scraping plate extending in a direction in which chips on the wire mesh are removed by advancing and retreating of the operating rod is swingably arranged, and a chip in a direction in which chips of the first operating rod are removed is provided. From the brush position at the stroke end, beyond the upper edge of the wall at the chip discharge side end of the cutting oil tank, a swash plate that guides and removes the chips to the outside of the cutting oil tank is disposed on the filter net, or The filter net itself is bent, and the cutting machine moves the first operating rod forward and backward in conjunction with the attachment and detachment of the workpiece, and eliminates chips from the first operating rod. The second operating rod is lowered during the stroke of the first operating rod, and the second operating rod is raised during the reverse of the direction of the first operating rod.

[0006]

When the direction of movement of the first operating rod is in the direction of removing chips on the filter net, the second operating rod is lowered, and the chip scraping plate is moved to a substantially horizontal portion and a slope of the filter net. The brush moves ahead of the brush in contact with and moves the chips in the discharge direction, after which the brush wipes the filter net. If there is no brush with only the scraping plate, fine chips remain and clogging occurs.If there is no brush with only the scraping plate, the brush bends and the chips cannot be moved and eliminated. By using the powder scraping plate and the brush together, it is possible to wipe off the fine chips remaining after removing most of the chips with the chip scraping plate with the brush.

[0007]

The first air cylinder device and the second air cylinder device operate in conjunction with a clamp cylinder device of a cutting machine for attaching and detaching a workpiece, and when the cutting machine is not operating. Since the chip removal device of the present invention also stops operating, the power is not wasted and the chips on the filter net are removed without any effort and the cutting oil overflows from the cutting oil tank. Flow can be prevented.

The longitudinal direction of the cutting oil tank having a rectangular horizontal section is arranged in parallel with the cutting machine, and chips on the filter net are removed from the longitudinal end of the cutting oil tank, and the cutting oil is cut into contact with the end wall. If a powder receiving box or a truck is arranged, the factory space can be used more effectively than a cutting oil filtration device using a rotating cylinder, which is arranged at right angles to the cutting machine.

As shown by an arrow 19, the second operating rod 13 rises in conjunction with the operation of the cutting machine together with the brush 14 and the chip scraping plate 15, and the brush 14 moves from the filter net 4 to the chip scraping plate. 15 moves away from the swash plate 16, and then the first operating rod 10 moves in the direction indicated by the arrow 20. (An example of an interlocking mechanism with the cutting machine 1 will be described later.) When the first operating rod 10 moves in the direction of arrow 20, the second operating rod 13 is raised, so that the brush 14 and the chip The approach plate 15 does not contact the chips on the filter net.

Next, as shown by an arrow 21 in FIG.
Of the operating rod 13 descends together with the brush 14 and the chip scraping plate 15, the brush 14 and the chip scraping plate 15 come into contact with the filter net 4, and the first operating rod 10 moves in the direction of arrow 22. hand,

To prevent clogging of the filter net.

With the single advance and retreat of the first operating rod 10, the chips separated on the filter net 4 are scraped to the middle of the swash plate 16, and the first operating rod 10 is moved forward and backward thereafter. Is pushed out of the cutting oil tank 3 through the chips scraped by the oil and discharged. The number of forward and backward movements of the first operating rod 10 until chips are discharged out of the cutting oil tank 3 depends on the stroke length of the first operating rod 10 and the length of the cutting oil tank 3 in the stroke direction. But,
In order for the cutting oil adhering to the chips to be sufficiently separated from the chips, the chips separated on the filter net 4 are discharged out of the cutting oil tank 3 by a plurality of forward and backward movements of the first operating rod 10. Preferably.

Various mechanisms for interlocking the first operating rod 10 and the second operating rod 13 with the cutting machine are conceivable, but FIG. 5 shows the simplest and lowest cost, and the chips actually separated on the filter net. This shows an interlocking mechanism that can eliminate. In FIG. 5, from 1 to 4,
Reference numerals 9 to 18 denote the same parts as those in FIG. 1, reference numeral 23 denotes an electromagnetic valve, reference numeral 24 denotes a power supply for controlling the electromagnetic valve 23, and reference numeral 25 denotes an electric current conducted to an exciting winding of the electromagnetic valve 23. Switch, 26 is a workpiece, 27 is a jig, 28 is a clamp cylinder device for attaching and detaching the workpiece to and from the chuck of the cutting machine 1, an arrow 29 is a factory airline, and an arrow 30 is the first The air discharged from the air cylinder device 9, the second air cylinder device 11, and the clamp cylinder device 28 is shown.

In the state shown in FIG. 5, that is, the first operating rod 10 retreats, the second operating rod 13 descends, and the brush 14 and the chip scraping plate 15 come into contact with the filter net 4, and the clamp cylinder 28 Work rod retreats and the chuck of the cutting machine 1
