Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a cutting fluid device used in a machine tool, and a mechanism for separating and collecting shavings such as fine chips easily accumulated in a cutting fluid tank and waste oil floating on the cutting fluid surface.

[0002]

[Prior Art]

 Conventionally, when cutting castings with lathes, machining centers, etc., the cutting fluid was not used, but in recent years high machining accuracy is required, and cutting fluid is used to improve accuracy. I have a lot of things.

[0003]

[Problems to be solved by the device]

 Generally, the cutting fluid needs to be separated into cutting chips and collected in the cutting fluid tank. Therefore, the hinge pan type chip conveyor 101 as shown in FIG. 4 or the scraper type chip conveyor 102 as shown in FIG. In many cases, the cutting fluid is placed on the top, and in this case, the cutting fluid is directly collected from the tray 104 of the chip conveyor to the cutting fluid tank. When steel is cut, there are very few chips that become fine powder, so it is unlikely that the chips will enter the cutting fluid tank together with the cutting fluid and accumulate in a mud state, but when cutting castings, a large amount of cutting fluid is used. There is a problem in that frequent maintenance inspections are necessary because it enters a tank and becomes a muddled state. The present invention has been made in view of the above problems of the conventional technology, and its purpose is to remove the dirt of cutting fluid by removing fine chips and oil at the outlet of the chip tray. The purpose of the present invention is to provide a mechanism for separating and collecting fine chips and oil in a cutting fluid device that can be reduced.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the separation and recovery mechanism of fine chips and oil of the cutting fluid device in the present invention is provided with a magnet drum for adsorbing fine chips and oil on the outlet side of the cutting fluid tray, and the cutting fluid and oil A separation tank, which is divided into a first chamber and a second chamber by a partition plate having a communication hole at the bottom for separating the two, is provided adjacent to the magnet drum, and the first tank of the separation tank is covered with the separation tank from the magnet drum. A mesh structure heddle tray for receiving fine chips containing cutting fluid and oil carried out by a plate is provided, and a waste oil tank for collecting oil flowing out from the upper part of the first chamber is provided adjacent to the separation tank, The cutting fluid from which fine chips and oil have been removed is collected in the cutting fluid tank, the fine chips in the hedoro tank, and the oil in the waste oil tank.

[0005]

[Action]

 The cutting fluid flowing in the cutting fluid pan toward the outlet is adsorbed by the magnetic drum near the outlet. The fine chips are scraped off by a scraping plate, carried out and dropped into the first chamber of the separation tank, and accumulated in the hedoro tray in the first chamber. The cutting fluid and oil are carried out together with the fine chips and accumulated in the first chamber. Then, due to the difference in specific gravity, only the cutting fluid is sent to the second chamber through the lower hole, overflows from the upper gutter, and is returned to the cutting fluid tray. Then, an oil layer is formed in the upper layer in the first chamber, and this oil overflows from the upper gutter and is collected in the waste oil tank.

【Example】

 Examples will be described with reference to FIGS. 1 to 3. Although this machine is not shown in the known lathe, the chuck 1 fitted to the spindle holds the workpiece W, and the turret 3 of the turret tool post 2 is equipped with a plurality of tools 4. A cutting fluid nozzle 5 for supplying a cutting fluid corresponding to the tool 4 is attached to the turret 3. A cutting fluid tank 10 is installed below the processing position, and a chip conveyor 11 is placed on it. The chip conveyor 11 may be either a hinge pan type or a scraper type, but since the chips are fine powder, in this embodiment, the hinge pan type conveyor 12 is hung on the rollers 13, 14, 15, 16 and the sprocket wheel 17 to endlessly. The rollers 13 and 14 of the chip receiving part on the lower side of the processing position are horizontal, the rollers 14 and 15 are uphill, and the rollers 15 and the sprocket wheel 17 are horizontal at a high position and are on the chip discharge side. .. When the shaft of the sprocket wheel 17 is rotated by the motor 18, the hinge pan type conveyor 12 is driven.

The frame of the chip conveyor 11 has an opening 12 at the upper part of the chip receiving part, a chip discharging part, and a magnet roller mounting part which will be described later, and the bottom of the chip receiving part is formed in the cutting fluid pan 19. ing. A magnet drum 22 is rotatably supported in front of an outlet 21 above the opening of the cutting fluid tank 10 of the cutting fluid tray 19, and the magnet drum 22 is rotated by a motor 23 via a reduction gear. A scraping plate 24 is attached to the magnet drum 22 with a downward slope, and the fine chips scraped off by the scraping plate 24 are separated into two chambers 25 a mounted on the cutting fluid tank 10. , 25b in one of the chambers (first chamber) 25a of the separation tank 25.

The fine chips scraped off by the scraping plate 24 contain a large amount of cutting fluid and oil, and the cutting fluid and oil that have dropped together with the fine chips are collected in the first chamber 25a. Then, only the cutting liquid having a large specific gravity is sent to the other chamber (second chamber) 25b through the communication hole 25d formed in the lower side of the partition plate 25c, and the liquid overflowing from the second chamber 25b is guttered. It is returned to the cutting fluid receiving tray 19 through 27. In addition, since the cutting fluid and oil collected in the first chamber 25a are returned to the second chamber only, the difference in specific gravity creates an oil layer in the upper layer, and the oil overflowing from the first chamber will gutter 28. It passes through and is stored in the waste oil tank 29. Further, a movable chip bucket 31 is installed below the discharge port of the chip conveyor 11.

Next, the operation of this embodiment will be described. When the cutting process is started while discharging the cutting liquid from the cutting liquid nozzle 5, the motors 18 and 23 are also rotated, the hinge pan type conveyor 12 is rotated in the arrow direction, and the magnet drum 22 is also rotated in the arrow direction. When the workpiece W is cut by the tool 4, the chips fall into the chip receiving portion of the chip conveyor 11 together with the cutting liquid, and relatively large chips are conveyed by the movement of the conveyor, and are discharged from the discharge part to the chip bucket 31. To be collected. The fine chips that have passed through the hinge portion of the conveyor 12 together with the cutting fluid flow toward the outlet 21 side of the bottom cutting fluid tray 19. Then, the fine chips are adsorbed by the rotating magnetized magnet drum 22 and carried in the direction of the arrow, scraped off by the scraping plate 24, and then dropped into the first chamber 25a of the separation tank 25, where they are placed in the first chamber. It is accumulated in the Hedoro saucer.

The fine chips conveyed to the separation tank 25 contain a large amount of cutting fluid and oil such as lubricating oil and hydraulic oil floating on the upper surface of the cutting fluid. This cutting fluid and oil utilize the difference in specific gravity. Only the cutting fluid is sent to the second chamber, and an oil layer is formed in the upper layer portion of the first chamber 25a. The oil overflowing from the first chamber is collected in the waste oil tank 29 via the gutter 28, and the cutting fluid overflowing from the second chamber is returned to the cutting fluid pan 19 via the gutter 27, and the fine chips are contained in the hedoro pan. It becomes a mud state and accumulates. The cutting fluid that has been cleaned by removing fine chips and oil in this manner is returned from the outlet 21 to the cutting fluid tank 10, and again sucked up by the pump and circulated.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Since the fine chips and oil in the cutting fluid are removed, the life of the cutting fluid is extended, and the maintenance cycle of the filter, etc. provided to prevent clogging of the pump and piping can be extended. ..
