Abstract

PURPOSE:To enable water to be injected continually toward a machining point, by fixing a nozzle to a gearing which coaxially rotates with a spindle matching with a movement of the machining point being able to be fixed to an optional position along the periphery of the spindle. CONSTITUTION:When a workpiece is machined by applying rotation to a machining tool 8 by a spindle 3, a device, which rotates a gearing 14 engaging a pin 24 with its toothed part 14b to fix the gearing 14 and injecting cooling water, delivered from a point end part 18a of an injection water nozzle 18, toward a machining point, performs adequate cooling while removes machining chips. Next, the device, when it machines the other surface of the workpiece, disengages the pin 24 from the toothed part 14b of the gearing 14 turning it for the machined surface and again setting the gearing 14 to be fixed so that the cooling water, delivered from the water injection nozzle point end part 18a, is injected toward the machining point. In this way, the device enables the water to be accurately injected to the machining point.

液や研削液吐出用の注水ノズルが設けられている。In recent years, from the perspective of streamlining and unmanned production lines, machining centers (
Multi-purpose machine tools) are widely used. This machining center is as shown in FIG. 7, and has a spindle 3 rotatably supported by a support part 2 via a bearing 1.
By engaging the gripped portion 6 at the upper end of the tool holder 5 with the chuck portion 4 provided on the lower end side of the spindle 3, the tool holder 5 is connected and fixed to the spindle 3,
A processing tool 8 is attached to the lower end of the tool connecting shaft 7 at the bottom of the tool holder 5 with a screw 10. Then, the spindle 3 is rotated to rotate the machining tool 8 together with the tool holder 5, and the rotating machining tool 8 is brought into pressure contact with a workpiece (not shown), thereby machining the workpiece. . In automatic machining using such a machining center, it is necessary to inject cooling fluid, grinding fluid, etc., as in normal machining operations, and a water injecting nozzle for discharging cooling fluid or grinding fluid is provided in the machining center.

いる。However, the reality is that the water injection nozzle is fixed at an appropriate location on the machining center, and water is injected from that location substantially in the processing direction. therefore,
Although it is originally desirable to focus cooling on the machining point where the machining tool and workpiece come into contact, the water injection ends up being off-target and the heat generated during machining cannot be effectively cooled down. This has caused problems such as severe damage to processing tools.

未だ実用化されていないのが現状である。Therefore, as shown in Figure 8, the water injection nozzle was made long and
The direction can be changed freely with fingers, and the water injection nozzle 9 can be moved appropriately by a person while observing the machining state. However, even with this water injection nozzle 9, the range in which water can be injected is limited, and the directional movement of the water injection nozzle 9 is also complicated, which causes problems in terms of usability. For this reason, it is desired to realize a water injection nozzle that always injects water toward the processing point, regardless of the position of the processing point, but it has not yet been put into practical use.

。In this configuration, during processing, cooling is first performed as shown in FIG. 3. That is, the machining tool 8 is rotated from the upper spindle 3 in the direction of arrow P, and machining is performed from point A to point B of the workpiece 21. At this time, rotate the gear ring 14 (Fig. 1) to position the coolant discharged from the tip 18a of the water injection nozzle 18 toward the machining point as shown by arrows Q and Q', respectively. At this position, the pin 24 is engaged with the teeth 14b of the gear ring 14 to fix the gear ring 14, allowing appropriate cooling and removal of machining debris. Subsequently, as shown in FIG. 4, when machining is performed from point B to point C on the workpiece 21, the machining tool 8
The movement relative to the workpiece 21 is as shown by the arrow R, and if the gear ring 14 remains as described above, the water injection nozzle tip 18a will be at the position indicated by the two-dot chain line 18c. Connect the pin 2.4 to the toothed part 1 of the gear ring 14.
4b, rotate the gear ring 14 by 90 degrees while watching the angle scale, and then engage the pin 24 with the teeth 14b again to fix the gear ring 14.
The coolant discharged from 8a is directed toward the processing point.
