Description

  The present invention particularly relates to a purification device that is installed in a cutting oil tank of a machine tool and removes debris by filtering the cutting oil before discharging cutting oil containing cutting chips to the cutting oil tank.

  When using a machine tool with a tool such as a bit to process a workpiece mainly made of a metal material by a method such as cutting or grinding, supply cutting oil or coolant to the cutting point and lubricate or cool the tool. In addition to removing and transporting chips. Since most of the workpieces are metal, the chips are also mainly metal scraps. In general, a machine tool is provided with a cutting oil tank that filters used cutting oil. After the cutting oil is discharged to the cutting oil tank, the cutting oil is supplied to the cutting point and recycled again. If not removed, the cutting oil is reused with a large amount of chips, adversely affecting the tool and workpiece. In order to prevent such a problem, a purification device for filtering the cutting oil has been devised.

  For example, Taiwan Patent No. 510250, “Purification Device for Filtering Oil with Metal Scrap” has a magnetic member that attaches and removes metal chips and removes from the lid of the cutting oil tank to the inside of the cutting oil tank. Although it is used by hanging, metal debris can be attached only to a certain thickness. In addition, since the said purification apparatus cannot adhere metal scraps other than the magnetic force range of a magnetic member, you have to arrange | position and use a several purification apparatus simultaneously. However, since the magnetic member is expensive, the cost is increased when a plurality of purification devices are used simultaneously.

  Further, a conventional chip cleaning device as shown in FIGS. 6 to 8 has been devised. The chip purification device includes a pipe (40) and a plurality of filters (50) surrounding an outer peripheral wall at the upper end and the lower end of the pipe (40), and a connecting tube (41) is provided at the upper end of the pipe (40). Provided. The connecting tube (41) is divided into an upper stage and a lower stage, and a bowl-shaped stopper (410) is provided at the boundary between the upper stage and the lower stage of the outer peripheral wall.

  Two elongated fixing members (42) are provided on the outer peripheral wall of the lower stage of the connecting tube (41), and the upper end of one fixing member (42) is one of the outer peripheral walls of the lower stage of the connecting tube (41). The upper end of the other fixing member (42) is welded to the other side of the outer peripheral wall sandwiching the shaft of the connecting tube (41). Two gaps are formed between the edge of one fixing member (42) and the edge of the other fixing member (42).

  A plurality of holding rings (43) are provided between the two fixing members (42), and the outer peripheral wall of each holding ring (43) is welded to the inner surface of the fixing member (42) and positioned at the bottom. A certain distance is placed from the holding ring (43) to the lower ends of the two fixing members (42).

  A sliding ring (45) is further provided between the two fixing members (42), and the sliding ring (45) is positioned under the lowermost holding ring (43). Part of the outer peripheral wall of the sliding ring (45) is in contact with the inner surface of the fixing member (42), and one sliding member (in each of the portions corresponding to the two gaps of the two fixing members (42)). 44).

  Each sliding member (44) is elongated and has a width corresponding to each gap in the two fixing members (42), and its upper end is welded to the outer peripheral wall of the sliding ring (45). The lower end is aligned with the lower end of the fixing member (42).

Between the two fixing members (42) and the two sliding members (44), a spring (46) positioned below the sliding ring (45) and a spring (46) are positioned. The support ring (47) is provided, and the outer peripheral wall of the support ring (47) has portions corresponding to the two fixing members (42) and the two sliding members (44), respectively, and the fixing member (42) The portions corresponding to and are respectively welded to the fixing member (42), and the portions corresponding to the sliding member (44) are in contact with the sliding member (44) but are not welded. ).
Between the lower ends of the two fixing members (42) and the lower ends of the two sliding members (44), a sliding plug (48) having a coaxial screw hole in the center is provided, and the sliding plug (48) The outer peripheral wall is welded to the sliding member (44), but is in slidable contact with the fixed member (42).
That is, the sliding member (44) integrated with the sliding ring (45) and the sliding plug (48) is integrated with the connecting tube (41) at the upper end and the support ring (47) at the lower end. The two fixing members (42) are slidably attached via the spring (46).

A washer (49) for holding the filter (50) is provided under the sliding plug (48), and the washer (49) corresponds to the stopper (410) of the connecting tube (41). And has a hole corresponding to the screw hole of the sliding plug (48). The washer (49) is attached to the bottom of the sliding plug (48) by a screw for screwing the hole and the screw hole of the sliding plug (48).
The plurality of filters (50) are provided between the stopper (410) and the washer (49) of the connecting tube (41), and the sliding ring (45), the sliding member (44), and the sliding plug (48). ), And the washer (49) attached to the sliding plug (48) is pushed up by the spring (46), so that the plurality of filters (50) are tightly sandwiched.

As shown in FIG. 9, in use, the purification device is attached to the lower surface of the lid (B) of the cutting oil tank (A), and the purification device is moved from the lid (B) to the inside of the cutting oil tank (A). hang. The upper stage of the connection tube (41) protrudes from the upper surface of the lid (B) and is connected to an external oil feeding pipe (not indicated).
The used cutting oil flows from the oil feed pipe into the pipe (40) of the purification device via the connecting tube (41). A plurality of filters (50) sandwiched between the stopper (410) and a washer (49) and provided on the outer peripheral wall of the pipe (40) allow the cutting oil to pass from the gap between the two fixing members (42). The sliding member (44) and the sliding member integrated with the sliding plug (48) receive the weight of the cutting oil that prevents the momentum flowing out, but the sliding plug (48) continues to flow from the oil feeding pipe. The ring (45) urges the spring (46) and slides downward. When the washer (49) slides downward along with it, the filters (50) are slightly separated from each other, and a gap is formed between the filters (50) to allow the cutting oil to flow out. It will be.
When the cutting oil flows out into the cutting oil tank (A) via the gap between the filters (50), the scraps such as the metal scraps that are contained adhere to the filter (50), and the cutting oil tank ( A) cannot be entered.

  Since the conventional purification device uses a low-cost filter, the cost can be reduced as compared with the invention of Taiwan Patent No. 510250.

  However, when manufacturing the pipe (40) of the conventional purification device, the connecting tube (41), each holding ring (43), and the support ring (47) are welded to one fixing member (42), Since the spring (46) and the sliding ring (45) are positioned at predetermined positions and the other fixing member (42) is welded, the sliding member (44) is welded to the sliding ring (45). The process for manufacturing the pipe (40) is extremely complicated, but requires a very long manufacturing time and is difficult to manufacture.

  The fixing member (42) is considerably long, and the portion from the lowermost holding ring (43) to the support ring (47) is not fixed by welding, but is not strong and deforms severely. easy. Further, if there is any welding defect even if the support ring (47) is a little, it will easily fall off due to deformation of the fixing member (42).
