Benefits of technology

The patent is about a coolant supply device that can improve chip removal in a machine tool by controlling the pressure of the coolant. This device uses a valve that is opened or closed by a predetermined pressure, which is controlled by an ejection pump. This helps to strengthen or weaken the coolant pressure, making it easier to remove chips from the machine. The device is cost-effective and provides better control over the coolant pressure. The ON / OFF state of the ejection pump is controlled based on time, resulting in better performance and accuracy. Overall, this coolant supply device simplifies the device and improves chip removal.

Problems solved by technology

Here, it is not efficient to manually discharge the accumulated chips by an operator.
As a result, a problem arises in that the cost of the device increases as a whole.
However, since this technique is mainly used to highly efficiently discharge chips by the pump having a small capacity, the electromagnetic valves need to be used.
Also, the cost of the device increases as a whole.

first embodiment

[0022]First, a coolant supply device according to the invention which performs a control of switching the ON / OFF state of a coolant ejection pump based on ‘time’ will be described with reference to FIGS. 1 and 2.

[0023]FIG. 1 is a view illustrating a coolant supply device and a chips washing pipe disposed inside a splash guard of a machine tool.

[0024]As shown in FIG. 1, a coolant which is stored in a coolant tank 1 is suctioned by a coolant ejection pump 2, is divided into a plurality of routes through a manifold 4 that divides a coolant passageway, and reaches an opening / closing valve 7 through a plurality of pipes 5. The opening / closing valve 7 is a valve which is opened when a predetermined pressure is applied to the valve and is not opened unless the predetermined pressure is applied thereto. For that reason, even when the coolant reaches the opening / closing valve 7 through the pipe 5, a certain degree of time is needed until the opening / closing valve 7 is opened. Since the openi...

second embodiment

[0040]Next, the coolant supply device of the invention performing the control of switching the ON / OFF state of the coolant ejection pump based on the ‘pressure of the coolant inside the pipe’ will be described with reference to FIGS. 3 and 4.

[0041]FIG. 3 is a view illustrating the coolant supply device and the chips washing pipe disposed inside the splash guard of the machine tool.

[0042]As shown in FIG. 3, the pressure sensor 3 is provided between the coolant ejection pump 2 and the opening / closing valve 7, and detects the pressure of the coolant ejected from the coolant ejection pump 2. As the pressure sensor 3, a sensor may be used which generates a signal when detecting a predetermined pressure. Meanwhile, the opening / closing valve 7 is a valve which is opened when a predetermined pressure is applied thereto and is not opened until the predetermined pressure is applied thereto similarly to the opening / closing valve 7 shown in FIG. 1. As a result, when the opening / closing valve 7 ...

Abstract

In a coolant supply device that supplies a coolant for washing chips into a machine tool, an opening / closing valve that is opened or closed by the pressure of the coolant is provided in the course of a pipe line supplying the coolant ejected from a coolant ejection pump into the machine tool. Meanwhile, an ON / OFF control is performed so that the coolant ejection pump is turned off when a first time elapses after the coolant ejection pump is turned on and the coolant ejection pump is turned on when a second time elapses after the coolant ejection pump is turned off.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a coolant supply device that causes a coolant for washing chips accumulated inside a machine tool to flow into an external chip receiving portion.[0003]2. Description of the Related Art[0004]When a cutting process is performed on a cutting target by using a cutting tool, chips are essentially produced. In the case of the cutting process using a machine tool, chips are accumulated inside the machine tool in an area surrounded by a splash guard, and hence the chips need to be discharged to the outside of the machine tool. Here, it is not efficient to manually discharge the accumulated chips by an operator. In many production sites, a coolant device has been used which causes chips accumulated in a machine tool to flow to the outside of the machine tool by using a coolant used for a cutting process.[0005]The coolant device washing the machine tool is equipped with an ejection pump supplying...
