Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chip discharging device attached to the side of a leg part of a machine tool, and more particularly to a chip discharging device provided with a coolant tank separated from the leg part.

[0002]

[Prior Art]

 Conventionally, as this type of chip discharging device, the techniques shown in FIGS. 4 and 5 are known. In the chip discharging device shown in FIG. 4, the gutter 22 is supported by the leg 1 of the lathe, the chip conveyor 23 is placed therein, and the coolant tank 24 can be pulled out from under the leg 1 on the lower side. It is installed in. In the chip discharging device of FIG. 5, the chip conveyor 23 is placed on the coolant tank 24.

[0003]

[Problems to be solved by the device]

 However, according to the conventional device of FIG. 4, since the chip conveyor 23 is placed inside the trough 22, when the chip conveyor 23 is installed and removed, the chip conveyor 23 is moved in the longitudinal direction to be put into and taken out from the trough 22. It was necessary to secure a wide floor space corresponding to the entire length of the chip conveyor 23 around the lathe. In the case of the conventional device shown in FIG. 5, the chip conveyor 23 can be moved while being placed on the coolant tank 24, which is convenient for installation and removal. However, when cleaning the coolant tank 24, the heavy chip conveyor 23 may be removed from the coolant tank 24. It was necessary to put it on and the work was difficult and troublesome.

Therefore, the problem to be solved by this invention is that it is not necessary to secure a large floor space around the machine tool, and the work for installing and removing the chip conveyor and the work for cleaning the coolant tank can be easily performed. An object is to provide a chip discharging device for a machine.

[0005]

[Means for Solving the Problems] In order to solve the above problems, a chip discharging device of the present invention is mounted on a trough supported by a leg of a machine tool and inside the trough. A chip conveyor, a cover plate that covers the side surface of the gutter so that the chip conveyor can be taken out and opened, a coolant tank that can be pulled out below the gutter, and an upper surface of the coolant tank It is composed of a jack.

[0006]

[Action]

 According to the above configuration, when the chip conveyor is installed and removed, the gutter is lifted by the jack, and with the cover plate removed from the gutter, the chip conveyor is moved in the width direction and easily put in and out of the gutter. it can. Therefore, it is not necessary to secure a large floor space around the machine tool. Also, when cleaning the coolant tank, it is possible to easily work by pulling out only the coolant tank from the bottom of the leg while the chip conveyor is still installed inside the gutter.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. A chip guide 2, a support piece 3, and a support arm 4 are provided on a leg portion 1 of the lathe. A gutter 5 is attached to the side of the leg portion 1, is supported from below by the support piece 3, and is suspended from above by a support arm 4 via a bracket 6. A chip conveyor 7 is placed inside the trough 5, and is configured to collect chips and coolant discharged from the processing section 8 of the lathe and convey the chips diagonally upward and discharge them. There is. The bottom of the gutter 5 is provided with a discharge hole 9 for discharging the coolant collected by the chip conveyor 7 downward. In addition, an opening 10 (see FIGS. 2 and 3) having a size that allows the chip conveyor 7 to be put in and taken out is formed on one side surface of the gutter 5, and a cover plate that covers the opening 10 so that the opening 10 can be opened and closed. 11 are attached by bolts 12. One of the brackets 6 is provided on the cover plate 11.

On the other hand, below the trough 5, a coolant tank 13 for storing the coolant dropped from the discharge hole 9 is installed by a caster 14 so as to be drawn out on the floor surface 15. A lid plate 17 having a hole 16 larger than the discharge hole 9 is attached to the upper surface of the coolant tank 13, and a screw type jack 18 for lifting the front end portion of the gutter 5 is attached to the upper surface of the lid plate 17. Is provided. Further, a cover 20 having a size capable of covering the gutter 5 from the side is detachably attached to a retaining piece 19 fixed to one side surface of the coolant tank 13 with a retaining metal fitting 21 on the rear surface thereof. (See Figure 2).

In the chip discharging device configured as described above, when the chip conveyor 7 is to be taken out, the cover 20 is removed, the jack 5 is used to lift the gutter 5 to support the weight of the chip conveyor 7, and the bolt 12 And the cover plate 11 is removed from the trough 5, and in that state, the chip conveyor 7 is pulled out in the direction of the arrow in FIG. The chip conveyor 7 is installed in the reverse order of the above. In this way, since the chip conveyor 7 can be moved in the width direction and taken out, it is not necessary to secure a large floor space around the lathe, and the space can be effectively used.

When cleaning the coolant tank 13, the cover 20 should be removed, the jack 18 should be separated from the bottom of the gutter 5, and the chip conveyor 7 should still be installed inside the gutter 5. , Only the coolant tank 13 is pulled out from the bottom of the leg 1 and cleaned. After the cleaning is completed, the coolant tank 13 is pushed under the gutter 5 and restored in the reverse order of the above. In this way, unlike the conventional case, the cleaning operation of the coolant tank 13 can be easily performed without the trouble of lowering and placing the chip conveyor 7.

The present invention can be applied to a chip discharging device for various machine tools other than a lathe, and the shape and configuration of each part are not limited to the above-mentioned embodiment, and the present invention is not limited thereto. It is possible to make appropriate changes without departing from the spirit of the above.

[0012]

[Effect of the device]

 As described above in detail, according to the present invention, the side surface of the gutter is openably and closably covered with the cover plate, the coolant tank is installed under the gutter so that the coolant tank can be pulled out, and the jack is provided on the upper surface of the coolant tank. Since it is provided, it is not necessary to secure a wide floor space around the machine tool, and it is possible to easily carry out the work of installing and removing the chip conveyor and the work of cleaning the coolant tank.
