Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutting tool sweeping device for a machine tool, and the chip sweeping means is arranged to face the cutting tool at a position before the cutting tool contacts the workpiece. It is an object of the present invention to provide a cutting tool sweeping device that can automatically remove chips attached to a cutting tool during cutting.

Using cutting machine tools, for example, drilling holes in metal plates, tapping,
When performing various operations such as reaming, if you take into consideration the following points: improving machinability, preventing wear of processing tools (e.g. drills, reamers, taps, etc.), and controlling accuracy, it is possible to ensure that chips generated during cutting are removed. At the same time, it is necessary to supply cutting fluid to the power tool.

Conventionally, these operations involve removing chips attached to the cutting tool using a brush with a handle each time a hole is drilled, and at the same time using the same brush or another brush soaked in cutting oil to remove the chips. Applying cutting oil to the cutting tool.

That is, in the past, these operations had to be performed independently for each hole machining, which resulted in extremely poor working efficiency and poor productivity.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

1 and 2 show a front view and a side view, respectively, of an embodiment of a cutting tool attaching device for a machine tool according to the present invention.

In the figure, 1 is a cutting tool such as a drill, reamer, tap, etc.
It is chucked by a chuck 2 and supported by a suitable member so as to be able to move vertically.

When using a cutting tool, rotate the cutting tool 1 and displace it downward so that, for example, a metal workpiece support part (
A workpiece 5 fixed on a table 3 (hereinafter referred to as a table) is cut.

Reference numeral 6 denotes a mounting base, and a magnet (6a) is fixed to the lower surface of the mounting base, which is placed on the table 3.

Reference numeral 7 denotes a brush part and oil cup support stand (hereinafter referred to as support stand), which is fixed on the mounting stand 6. On the bottom of the brush support part 8, which will be described later, partially protrudes to the left in the figure, as shown by the arrow. The oil supply plate 9 extends from the inner wall surface to the oil grooves 8a and 8b of the brush support 8.
is fixed at an angle so that the left side is lower in the figure.
An oil drip opening 10a of an oil cup 10 containing cutting fluid is fitted and fixed on its upper surface.

The oil grooves 8a and 8b have, for example, a V-shape, and are provided at a predetermined interval on the brush support portion 8 so as to be inclined so that the left side in the figure is lower.

The opening surfaces of the left end portions of the oil grooves 8a and 8b are formed so as to occupy approximately - the height of the left end portion of the brush support portion 8.

Reference numeral 8□ denotes a soft brush made of, for example, boar hair, and is implanted in the upper half of the left end of the brush support 80 in the figure, excluding the opening surfaces of the oil grooves 8a and 8b.

8□ is a hard brush made of brass, for example, and is implanted in the lower half of the left end of the brush support 8 adjacent to the soft bristles 8□.

In addition, the soft brush 81 and the hard brush 8□ are the cutting tool 1
The cutting tool 1 is provided at a position where the cutting tool 1 passes through the brush when the brush is vertically displaced.

When in use, operate the adjustment screw 10b provided on the oil cup 10 to drip an optimum amount of cutting fluid onto the oil supply plate 9 from the oil dripping port 10a, and then drop the optimal amount of cutting fluid onto the oil supply plate 9.
, 8b to the soft brush 8□.

As a result, the soft brush 8□ always contains cutting fluid.

In this case, rather than having the hard brush 82 contain the cutting fluid, it is better to have the soft brush 81 contain the cutting fluid so that the cutting fluid can be retained more satisfactorily.

Here, when the cutting tool 1 is displaced downward, the cutting tool 1 passes through the soft brush 81 and the hard brush 82, reaches the workpiece 5, and performs cutting.

At this time, the cutting tool 1 is a soft brush 81 containing cutting fluid.
As it passes through, it is coated with cutting fluid.

When the cutting process is completed and the cutting tool 1 is displaced upward, the cutting tool 1 is again moved to the hard brush 8 □ and the soft brush 8 . Since the chips pass through the cutting tool 1 during cutting, the hard brush 8□ can reliably remove the chips that have adhered to the cutting tool 1, and the soft brush 8□ can reliably remove the chips from the cutting tool 1. Can be coated with oil.

In addition, since the hard brush 8□ is provided below the soft brush 8□, the chips attached to the processing tool 1 are surely removed by the hard brush 82 when the cutting process is finished. The cutting oil can be applied from the soft brush 81 to the inside of the soft brush 8□, and there is no risk of chips adhering to the inside of the soft brush 8□.

As described above, according to the device of the present invention, it is possible to automatically remove chips and apply cutting oil at the same time as cutting, and
Since the dripping amount of the cutting oil can be adjusted, there is no waste in lubricating, and furthermore, the table 3 is not contaminated with the cutting oil.

Note that if the soft brush 81 and the hard brush 8□ become unusable due to wear or damage, the brush support section 8 is replaced with a new one and mounted on the support stand 7.

Since the brush support part 8 is configured to be able to slide in the directions of the arrows a and b, as the cutting tool 1 is laterally displaced depending on the cutting position, the brush support part 8 is moved in the directions of the arrows a and b.
By slidingly displacing it in the b direction, the cutting tool 1 can be supported at an optimum position where it can always pass through the soft brush 81 and the hard brush 8□.

Furthermore, since the mounting base 6 is mounted and fixed on the table 3 by a magnet 6a provided on its lower surface, it can be easily moved and can be positioned below the cutting tools of various machine tools for each type of work. obtain.

As described above, the cutting tool sweeping device for a machine tool according to the present invention includes a sweeping means for sweeping away chips and the like attached to the cutting tool.
The cutting tool is configured with a brush member consisting of at least a hard brush and a soft brush, and the hard brush is on the side of the workpiece to be cut, and the soft brush is on the side of the cutting tool. Since the cutting tool is placed so as to face the cutting tool at a position before contact, the sweeping means automatically removes the cutting tool as the cutting tool contacts and separates from the workpiece support during cutting. This can improve work efficiency and productivity compared to the conventional method in which chips were removed using a brush or the like after each hole drilling. Also, since the means for supplying cutting fluid to the cutting tool is arranged in relation to the soft brush, the cutting region can be automatically removed during cutting, and the cutting fluid can also be automatically supplied to the cutting tool. As a result, 1
Work efficiency can be improved compared to conventional methods, in which chips are removed with a brush or the like and cutting oil is applied to the cutting tool with a brush or the like after each machining process. Since the cutting fluid can be sufficiently retained and the cutting tool passes through the hard brush and the soft brush, the chips attached to the cutting tool during cutting can be reliably removed by the hard brush, and the cutting fluid can be removed by the soft brush. Cutting fluid can be applied to the cutting tool from which chips have been removed.Also, since the hard brush is provided below the soft brush, the chips attached to the tool can be removed when the cutting process is finished. After reliably removing the chips with a hard brush, the cutting oil can be applied with a soft brush, which has the advantage that there is no risk of chips adhering to the soft brush.
