The ball 120 is formed so that its upper and lower surfaces are parallel to each other and the side surface thereof is curved so as to correspond to the ball receiving hole 110b.

The guide grooves 120b are formed to have the same depth.

And the lower end of the guide groove 120b is located on the upper side of the lower surface of the ball 120. [

As described above, according to the coolant nozzle apparatus of the present invention, since the guide member firmly supports the ball, the coolant spray angle of the ball can be maintained at the initial set angle even if the coolant is sprayed at a high pressure.

1 is a sectional view showing an example of a conventional coolant nozzle device,
FIG. 2 is a perspective view showing a coolant nozzle device according to an embodiment of the present invention, and FIG.
3 is a sectional view taken along the line III-III in Fig.

Hereinafter, a coolant nozzle device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It should be understood that various equivalents and modifications may be present.

1, a coolant nozzle apparatus according to an embodiment of the present invention includes a nozzle housing 110, a ball 120, a fixing bolt 130, and a guide member 140. As shown in FIG.

Here, the nozzle housing 110 is mounted on one side of a spindle of the machine tool (tool-side disk or tool holder side of the machine tool), and the coolant inlet hole 110a and the ball receiving hole 110b communicate with each other . At this time, the ball receiving hole 110b has a cylindrical shape and its diameter is formed to be larger than the diameter of the coolant inlet hole 110a to form a step with the coolant inlet hole 110a.

Further, a support ring 115 for supporting a lower portion of the ball 120 may be further provided at a bottom edge of the ball receiving hole 110b.

The upper portion of the ball 120 is exposed to the outside of the nozzle housing 110 and the lower portion of the ball 120 is seated at the bottom of the ball receiving hole 110b of the nozzle housing 110. A coolant injection hole 120a communicating with the coolant inlet hole 110a is vertically formed at the center of the ball 120. The coolant injection hole 120a is vertically formed in the direction of the coolant injection hole 120a And a plurality of guide grooves 120b are formed at regular intervals. In addition, the ball 120 may be formed to be flat so that the upper and lower surfaces thereof are horizontal to each other, and the side surface may be curved so as to correspond to the ball receiving hole 110b. 2, the lower end of the guide groove 120b is located at a position higher than the lower surface of the ball 120, and the guide groove 120b ) And the ball receiving hole (110b) so as not to be leaked to the outside of the nozzle housing (110).

2, the fixing bolt 130 is positioned near the ball receiving hole 110b of the nozzle housing 110, and a thread is formed on the lower circumferential surface of the fixing bolt 130 to fasten the nozzle housing 110 And a support portion 132 formed at an upper end of the coupling portion 131 and having a diameter larger than that of the coupling portion 131. [
