It moves downward by a rotational drive of a screw member (not shown) to a feed screw (not shown) fixed vertically on the Y-direction slider 5 via a power transmission mechanism (not shown) by control.
Thus, automatic drilling of a predetermined depth is performed while the Z-direction slider 5 is moved downward.

In the above drilling operations, for example, by using an anhydrous air reflux type cooling system that can be cooled by recirculating air to the tip of the drill, industrial waste disposal can be reduced, and on-site cleaning operations can be reduced.
Furthermore, for example, by installing a dust suction cover, dust can be vacuumed, and workability and environmental performance can be improved.

For example, when the Z-direction slider 5 reaches the lowest point position, an extension shaft prepared separately is connected to the upper end of the drill shaft 96 with a key joint or the like as necessary, and then continued. To drill to a predetermined depth.
The above automatic drilling is appropriately performed on the upper surface of the lower column P1 in accordance with a predetermined position and number determined in advance.
Thereafter, after removing the hole drilling device, the seismic isolation device (not shown) is fixed on the upper surface of the lower column P1 using the drilled anchor hole.

That is, after the drill shaft 96 having the above-described drilling bit 97 is pulled downward from the gear box 7, the drill shaft 96 having the grinding bit 98 is inserted into the gear box 7 from below and loaded as shown in the figure. .
Thus, by mounting the drill shaft 96 having the grinding bit 98, the upper surface of the lower column P1 after the above-described drilling can be automatically ground.

In the above embodiment, the drilling and grinding of the narrow space where the pillar is cut is performed, but the present invention is not limited to this, and the narrow space between the wall and another structure is used. It is also possible to perform drilling and grinding in other narrow spaces. Furthermore, not only drilling and grinding from above, drilling and grinding from the side and drilling and grinding from below are possible.
In addition, it is needless to say that other detailed structures can be appropriately changed.

It is a front view which shows the structure of one Embodiment of the drilling apparatus to which this invention is applied. It is a top view of the hole drilling apparatus of FIG. It is a side view of the hole drilling apparatus of FIG. It is the front view which showed the state which mounted | wore the grinding bit with the hole drilling apparatus of FIG.
