[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for separating cutting oil used in cutting in machine tools such as lathes, gear cutting machines, and broaching machines from cutting chips.

[0002]

[Prior Art]

 When cutting metal products, it is common to use cutting oil to reduce the cutting friction between the cutting tool and the processing material, to cool the processing material and to make the finished surface more beautiful. After cutting, it is necessary to separate this cutting oil discharged with the chips from the chips.

Therefore, as this type of cutting oil separating device, a magnet roller conveyor having a built-in magnet in a machine tool is adopted (Japanese Utility Model Laid-Open No. 58-110621), or a magnetic screw conveyor is attached to cut chips. It is proposed to discharge the cutting oil to the outside of the machine tool, and to naturally drop the cutting oil during the discharging to separate the cutting oil (Japanese Utility Model Publication No. 59-16 2944).

However, it is difficult to completely separate the cutting oil from the chips with the conventional cutting oil separation device as described above, and most of the cutting oil is discharged together with the chips adhering to the chips. Therefore, the chips discharged from the magnet roller conveyor or the magnet screw conveyor are subjected to a centrifugal separator to forcibly separate the cutting oil from the chips, or as shown in Fig. 4, the upper end is open and the net is on the outer periphery. A rotating car C having a porous material H stretched therein is rotatably provided in the separation tank T, and the rotating car C is rotated by a power of a motor or the like via a rotating shaft S. A derivative F provided with a spiral guiding flange Fa is placed in the upper and lower open cylinders P, chips M 1 are introduced from the upper opening Pa of the derivative F, and the cutting water W is generated by the centrifugal force of the rotating cage C. And separate the discharge paths MM and W There is one configured to discharge from M (Japanese Utility Model Laid-Open No. 60-1458).

[Problems to be solved by the device]

 However, as mentioned above, when a centrifugal separator or a cutting water separation / collection device is used, the separation effect seems to be great, but the investment cost is high and the power cost of the motor etc. is necessary. However, there is a problem that the maintenance and inspection is troublesome and a large installation space is required.

[0006]

[Means for solving problems]

 The present invention was made in order to solve the above-mentioned conventional problems, and an object thereof is to provide a simple structure and easy maintenance and inspection. The chip receiver, which has a chip discharge part at one end and a cutting oil discharge part at the other end, is supported so as to be swingable by inclining downward to the cutting oil discharge part side. A rolling weight is provided on the side surface of the chip receiver so that it moves between the center of the chip receiver and the chip discharge side when the chip receiver is inverted and inclined downward toward the chip discharge part. A cutting oil separation device is characterized in that it is configured to move to the discharge part side and discharge chips.

The side wall 3 is closed to form a cutting oil discharge part 4, and the right end side is opened as a chip discharge part 5. In the inside of the chip receiver 2, the right end side (chip discharge part side) from the central part is defined as a chip storage part 2a, and the chip storage part 2a is located immediately below the discharge port 1. Is distributed to.

Reference numeral 6 denotes a weight provided on the bottom surface of the chip receiver 2 on the cutting oil discharge part 4 side, which is configured so that it can be finely adjusted. Is provided with a rolling weight 7 that moves between the right end and the right end. The rolling weight 7 is a rectangular parallelepiped closed container 7A fixed along the right end from the central portion of the chip receiving container 2 and the container. And a roller 7B that rolls in the container 7A. The roller 7B is provided at the left end of the closed container 7A (when the chip receiver 2 is inclined downward toward the cutting oil discharge part). It is located in the center).

Reference numeral 8 denotes a support portion that supports the chip receiver 2, and has a structure in which a cross member 8B is horizontally installed between the upper ends of columns 8A standing upright and left. The cross member 8B and the chip receiver 2 are The central portion is pivotally connected by a hinge portion 9 such as a hinge so as to be swingable. Here, in the normal state, the chip receiver 2 is set so as to slightly descend and incline toward the cutting oil discharge part 4 side with the pivotal part 9 as a fulcrum. Maintained by 10.
