Abstract

A coolant supply device 1 includes a coolant tank 2 storing coolant therein, a mounting member 14 covering a part of an upper opening of the coolant tank 2, and supply pumps 32, 33, 34 mounted to the mounting member 14 and configured to pump up coolant C from the coolant tank 2 and supply the pumped-up coolant C to predetermined destinations. The coolant supply device 1 is configured such that the coolant C supplied to the predetermined destinations by the supply pumps 33, 34 is returned to the coolant tank 2. The mounting member 14 is supported by support members 16, 17, 18 such that it is slidable to a non-covered side of the upper opening of the coolant tank 2.

First claim

What is claimed is:

1. A coolant supply device attached to a machine tool to supply coolant to a machining area and other areas of a machine tool, the coolant supply device comprising:
a coolant tank storing coolant therein;
a mounting plate covering a part of an upper opening of the coolant tank; and
a supply pump mounted to the mounting plate and configured to pump up the coolant stored in the coolant tank and supply the pumped-up coolant to the machine tool,
the coolant supply device being configured such that the coolant supplied to the machine tool by the supply pump is returned to the coolant tank through a predetermined flow path,
the mounting plate being supported by a support member such that the mounting plate is slidable to a non-covered side of the upper opening of the coolant tank,
the coolant supply device further comprising a lid body arranged to cover the upper opening of the coolant tank adjacently to the mounting plate and to be attachable to and detachable from the coolant tank,
the upper opening of the coolant tank being configured to be closable by the mounting plate and the lid body,
when the lid body is detached from the coolant tank, the mounting plate with the supply pump mounted thereto being slidable to a side previously covered by the lid body.

2. The coolant supply device of claim 1 , wherein:
a cable connected to the supply pump is disposed along a sliding direction of the mounting plate on one side end side of the mounting plate; and
the mounting plate has a cover portion for covering the cable.
