CHIP DISPOSAL DEVICE OF MACHINE TOOL

摘要

To provide a chip disposal device of a machine tool which surely separates and collects a cutting fluid adhering to a chip lump, thereby capable of reducing an amount of the cutting fluid discharged to the outside of the machine. The chip disposal device includes a liquid separating part 65 which separates and collects a cutting fluid adhering to chips, the liquid separating part 65 has a mounting part 66 which is provided continuously from an inclined discharge surface 20a and is inclined so as to get lower as it goes more apart outward from the inclined discharge surface 20a, and to which a first chip lump a1 conveyed by a first scraping plate 36a is transferred. Then, the first chip lump a1 on the mounting part 66 stays on the mounting part 66 until dropping by being pushed by a second chip lump a2 conveyed by a second scraping plate 36b following the first scraping plate 36a.

主权项

1. A chip disposal device of a machine tool, the chip disposal device comprising:
a device casing having a storage tank to/in which chips and a cutting fluid are dropped and stored; a chip conveyor which has a pair of endless driving members moving round inside and outside the storage tank and scraping plates disposed between the driving members at an interval in a moving direction and which discharges the chips from the inside of the storage tank to the outside of the storage tank along an inclined discharge surface of the device casing; and a liquid separating part which is provided on a portion, of the inclined discharge surface, above a liquid level of the storage tank to separate and collect the cutting fluid adhering to the chips, wherein the liquid separating part has a mounting part which is provided continuously from the inclined discharge surface and is inclined so that a portion thereof more apart outward from the inclined discharge surface gets lower and to which a first chip lump conveyed by the first scraping plate is transferred, and wherein the first chip lump on the mounting part stays on the mounting part until dropping by being pushed by at least one second chip lump conveyed by at least one second scraping plate which follows the first scraping plate, and while the chip lump stays, the cutting fluid adhering to the chips is separated and collected.
