Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically applying cutting oil to a cutting tool.

[0002]

2. Description of the Related Art There are roughly three methods of adding an automatic oiling device to a conventional drilling machine. As shown in FIG. 4, the tank 5 is installed on the head 1 and the cutting oil 2 flows from the nozzle 9.
5, a method for adding a device for dropping 5 by its own weight, as shown in FIG.
The method of adding a device for injecting cutting oil 25 from the above into a mist state, and as shown in FIG. 6, the injected cutting oil 25 flows through the groove 17a provided in the table, flows into the discharge port 17b at the center, and is discharged. The tank 5 is arranged on a drilling machine equipped with a recovery table 17 having a function of returning to the tank 5 through the hose 18 connected to the outlet 17b, and the pressure of the pump 6 is used to inject oil from the nozzle 9 to collect the cutting oil 25. There is a method of adding a device for recovering at 17 and returning to the tank 5.

Further, as shown in FIG. 7, a drilling machine equipped with an automatic oiling device from the beginning has a base 19 with a built-in tank in which a tank is installed in the base, and oil is injected from a nozzle 9 by press-fitting a pump 6, and a recovery table. There is a device for collecting the cutting oil 25 in the tank built-in base 19 at 17.

[0004]

In the conventional automatic oiling device added to the drilling machine, the cutting oil 25 cannot be recovered as shown in FIGS.
5 and the cutting chips generated during processing must be cleaned. Further, in the case of FIG. 5, it was necessary to prepare a compressor separately from the lubrication device. Therefore, cutting oil 25
In order to collect the oil, it is necessary to change the table to a type capable of collecting the cutting oil 25 or replace it with an expensive drilling machine equipped with an automatic oiling device as shown in FIG.

An object of the present invention is to solve the above-mentioned problems of the prior art and to collect cutting oil and cutting debris lubricated at the time of machining a boring machine, and to provide an automatic lubricating device for a boring machine not equipped with a table for collecting cutting debris. Is to be able to attach.

[0006]

[Means for Solving the Problems] The above object is to install a column on a base, fit a table on which a workpiece is placed in the central portion of the column so as to be vertically movable, and attach a cutting tool to the upper end of the column. A drilling machine provided with a head for supporting and rotating, having a tank filled with cutting oil, connecting a hose to a pump arranged in the tank, and providing a nozzle connected to the anti-pump side of the hose at a suitable position in the drilling machine. It is achieved by fixing with a fixing means, arranging a pan for collecting cutting oil on the upper part of the base, and providing a flow path for the cutting oil to flow into the tank in the pan.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an overall front view of an automatic oiling device for a drilling machine, and FIG. 2 is a sectional view of a flow path portion of a tray and a tank.

In FIG. 1, a column 2 is erected on a base 4, and a table 3 on which a processed material 14 is placed is vertically movably fitted to the central portion of the column 2. The head 1 is provided on the upper end of the column 2, a drill 13 that is rotated by a motor (not shown) is attached to the head 1, and the drilling material 13 is used for drilling.

A tank 5 filled with cutting oil 25 is used as a base 4
A pump 6 is disposed in the tank 5 adjacent to. A hose 7 is connected to the pump 6, and a valve 8 and a nozzle 9 that adjust the discharge amount of the cutting oil 25 are connected to the opposite pump side of the hose 7. The nozzle 9 is movably fixed to the table 3 by a magnet base 10 and faces the drill 13. A saucer 11 is detachably arranged under the table 3, and the saucer 11 is supported by the tank 5 and legs 12. As shown in FIG. 2, the discharge port 21 of the tray 11 is inserted into the recovery hole of the tank 5.
Is used as a flow path 24 for collecting the cutting oil 25, and the filter 20 is provided between the tray 11 and the discharge port 21.
Is provided.

In the above structure, when a switch (not shown) is turned on and the pump 6 is driven, the cutting oil 25 passes through the hose 7 as shown by the arrow and is discharged from the nozzle 9 toward the drill 13. The discharge amount of the cutting oil 25 is adjusted by the valve 8, and the direction of the nozzle 9 is adjusted by the magnet base 10. The injected cutting oil 25 flows down the table 3 as shown by the arrow, is collected by the pan 11, changes the height of the leg 12 screw-fitted to the pan 11, and adjusts the inclination of the pan 11 to the right. By doing so, it is returned to the tank 5 through the flow path 24. Further, cutting chips generated during drilling also fall into the tray 11, but by collecting the cutting chips with the filter 20, the cutting chips are prevented from flowing into the tank 5, and the cutting chips are received.
If it accumulates on the top of the tray 1, remove the tray 11 and sprinkle the cutting chips.

FIG. 3 is an overall front view of an automatic oiling device showing another method of arranging flow paths and tanks. As shown in FIG. 3, when the automatic oiling device is mounted on the drilling machine installed on the work table 23, the saucer 11 is arranged on the base 4.
The pipe joint 22 is fitted to the discharge port 21 of the tray 11, the hose 18 is connected to the pipe joint 22, and the cutting oil 25 passes through the hose 18 as shown by the arrow and is supplied to the tank 5 arranged below the work table 23. Return.

Although the method of disposing the two flow paths and the tank 5 has been described in the present embodiment, the point is that the tank 5 is disposed below the tray 11, and the discharge port 21 of the tray 11 and the tank 5 are arranged. If the flow path is provided between the automatic recovery device and the recovery hole, the automatic lubrication device can be attached to various drilling machines, regardless of the above-mentioned arrangement method.

[0013]

According to the present invention, when drilling using the automatic oiling device, the automatic oiling device is attached to the drilling machine which is not equipped with the recovery table so that the cutting oil and the cutting waste can be collected. It saves you the trouble of replenishing the tank with cutting oil or cleaning the cutting oil and cutting dust scattered on the floor.
Since the tank can be arranged in any way, it can be mounted on a tabletop drilling machine.

Further, since the structure of the above device is simplified,
It is possible to provide an automatic oiling device for a drilling machine that is inexpensive and has good workability.
