Abstract

A chip discharge device of a machine tool includes a coolant tank storing coolant which is supplied to and dropped from a machining point, and a chip conveyor discharging chips which are generated at and dropped from the machining point, to an outside of the machine tool. A bottom wall of the coolant tank is inclined in a chip discharge side by mounting the coolant tank to the bed.

First claim

What is claimed is:

1. A chip discharge device of a machine tool comprising:
a coolant tank being provided beneath a bed and storing coolant which is supplied to a machining point and dropped, the coolant tank having a bottom wall; and
a chip conveyor being provided inside the coolant tank and discharging chips, which are generated at the machining point and dropped, to an outside of the machine tool, wherein
the bottom wall of the coolant tank is downwardly inclined as the bottom wall extends to a chip discharge side by mounting the coolant tank to the bed.

2. The chip discharge device of the machine tool according to claim 1 , wherein
the coolant tank includes an end part, which is an opposite side of the chip discharge side, and
the coolant tank is mounted on the bed at the end part.

3. The chip discharge device of the machine tool according to claim 2 , wherein
an inclination angle of the bottom wall is changeable by changing a height position where the end part of the coolant tank is mounted to the bed.

4. The chip discharge device of the machine tool according to claim 3 , further comprising:
a mounting bracket formed at the end part of the coolant tank,
wherein the mounting bracket is screwed and fixed to a supporting boss part which is formed in an opposite part of the mounting bracket on the bed, and an inclination angle of the bottom wall is changeable by changing a thickness of a shim plate which is interposed between the supporting boss part and the mounting bracket.

5. The chip discharge device of the machine tool according to claim 1 , wherein
the bottom wall includes a chip discharge end and an opposite end being opposite to the chip discharge end, and
the chip discharge end is closer to the bed in a vertical direction than the opposite end to the bed in the vertical direction.
