Description

[Detailed description of the invention] [Field of industrial application] The present invention is a cutting oil nozzle for a chip flow path that is installed in a chip flow path in the bed of a machine tool and is suitable for supplying cutting oil to the flow path. It's about structure.

[Conventional technology]

Chips generated during machining fall onto the bed of a machine tool along with cutting oil. A chip flow path is provided in the bed to allow the chips to flow out to a chip processing device such as a chip conveyor. Since cutting oil alone, which is discharged to the bed side together with the falling chips, cannot drain the chips, a cutting oil nozzle is attached to the bed to actively supply cutting oil. In the prior art, a device was installed in the bed to allow cutting oil to flow out from a relatively wide opening that spread laterally.

[The problem that the idea attempts to solve]

The prior art has problems in that it occupies a relatively large area and is expensive. Furthermore, when attaching the bed, it is difficult to screw the bed itself to the bed, so a joint is required, which complicates the structure. Furthermore, there was a problem in that the cutting oil did not flow out evenly and the cutting oil was supplied locally, making it impossible to sufficiently drain the chips. Also, cutting oil was clogging inside the nozzle.

The present invention solves the above problems, and is easy to install on the bed, can uniformly supply cutting oil over a wide range, is inexpensive, does not take up much installation space, and has a chip flow path that does not cause cutting oil clogging. The purpose of this invention is to provide a cutting oil nozzle structure.

[Means to solve the problem]

For this purpose, the present invention provides a cutting oil nozzle structure for supplying cutting oil to a chip flow path formed in the bed of a machine tool, which includes a pipe screwed onto a predetermined location of the bed and communicating with a cutting oil supply source. , a cap-like cover member disposed on the cutting oil outlet side of the pipe so as to cover it, and comprising a cap lid portion formed by cutting out a part of the cover member on the cutting oil supply side. This constitutes the cutting oil nozzle structure of the chip flow path.

[Effect]

Cutting oil is introduced into the pipe from a cutting oil supply source,
It flows upward from this outlet. Above the outlet, there is a cap-shaped cap with a part cut out, and the spilled cutting oil collides with the uncut cover of the cap, reflects to the notch side, and from there, the cutting oil from the bed is released. Dissipated into the flow path. This makes it possible to supply cutting oil radially and uniformly.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

3 and 4 show an example of the bed 6 of a machine tool. The bed 6 is formed from a frame 7 that surrounds the periphery and forms a bottom 8, a channel in which mortar, etc. is formed on the bottom 8 of the frame 7, a guide rail 9, a jig stand 10, etc. . As shown in Fig. 4, the flow path consists of a vertical chip flow path 11 consisting of a concave groove, and a transverse chip flow path 12 orthogonal or oblique to this, and the vertical chip flow path 11 is located on the left side of the figure. It slopes downward to the right, allowing chips to flow out to a chip conveyor (not shown) or the like. Further, the horizontal chip flow path 12 is formed to be inclined downward toward the vertical chip flow path 11 so as to transport the chips to the vertical chip flow path 11 side. A large number of cutting oil nozzles 1, which are the object of this embodiment, are arranged near the periphery of the bed 6.

1 and 2 show the detailed structure of the cutting oil nozzle 1. FIG.

A nut 4 is fixed to the bottom 8 of the bed 6.
Pipe 2 consists of a simple hollow pipe, with nut 4
is screwed onto. Cutting oil from a cutting oil supply source (not shown) is supplied to the pipe 2 from arrow A, and is discharged upward from its discharge port 2a.

A hat cover part 3 is provided above the pipe 2 to cover it, and is fixed to the pipe 2. Hat lid part 3
is formed in the shape of a canopy, and its top is placed at a position exactly facing the outlet 2a of the pipe 2. The hat cover part 3 has a part of the cover member cut out, and the cover part 3
a and a notch 3b are formed. The cover part 3a is the second
As shown in the figure, the cutout portion 3b is set back by an angle θ so that the area of the cutout portion 3b is larger than that of the cover portion 3a.

In this embodiment, θ=15 degrees, but the angle is not limited to this. As shown in FIG. 3, the notch 3a is
The vertical chip flow path 11 and the horizontal chip flow path 12 are all arranged facing in the flow direction.

When the cutting oil is supplied into the pipe 2, the cutting oil flows from the outlet 2a as described above, but a part of it flows out from the notch 3b to the flow path side without colliding with the cover 3a. However, a part of it collides with the back surface of the cover part 3a and is reflected as shown in FIG.
Head to the b side. Since the notch 3b is formed in a substantially semicircular shape, the reflected cutting oil is radially dispersed as shown in FIG. Since the notch 3b faces the flow path side as described above, the dissipated cutting oil flows out widely and uniformly toward the vertical chip flow path 11 and the horizontal chip flow path 12, and flows along the downward slope thereof. It flows out together with chips. This makes it possible to form a reliable chip flow path.

By arranging the cutting oil nozzles 1 at appropriate intervals, the dispersed cutting oil can be uniformly supplied to the flow path without interfering with each other.

In the cutting oil nozzle 1 of this embodiment, the pipe 1 is removably screwed onto the nut 4 at the bottom 8 of the bed 6, and assembly is extremely easy. Moreover, since it is formed from the pipe 2 and the hat lid part 3, there is no possibility that the nozzle will become clogged. Further, the structure is extremely simple and can be formed at low cost. Even if a failure occurs, it can be easily replaced. Furthermore, since the dissipation efficiency is excellent, it does not take up much space and does not get in the way.

In this embodiment, as shown in FIGS. 3 and 4, the cutting oil nozzle 1 is provided in the bed 6.
The shape of is not limited to this. Further, the shape of the hat lid part 3 is not limited to that shown in the drawings.

[Effect of idea]

As is clear from the above explanation, this embodiment is easy to install on the bed, can uniformly supply cutting oil over a wide range, is inexpensive, does not take up much installation space, and does not cause cutting oil clogging. You can increase the effect.
