Is selected and set as the stop index 36 in which is drilled. At the same time, any of the through holes 35a, 36a of the stop indicators 35, 36
Is set.

When the first drilling position is determined, in the case where the mounting hole for mounting the Braille base 101 is drilled in the square stone material 100 described above, the second table 30 constituting the second table 30 is formed.
A second row of drilling a row of mounting holes on the auxiliary table 31 side
A specific through hole 35a of the stop index 35 of the table 30 is selected, and in the case of FIG. 11 and FIG.
First, three mounting holes are drilled in the length direction of 0a, 10b.
Each time the stop index 26 of the table 20 is selected and the mounting hole is drilled, the first table 20 sequentially moves the stop index 26 to the adjacent through-hole 36a, and performs the drilling operation there.

Next, the vibration type electric drill 9 during the drilling operation
Operation 5 will be described.

Attached to the clamp mechanism 90, the drill blade 96
So-called vibration type electric drill 9 that vibrates in the length direction of
When the drill blade 96 is rotated to rotate the operation lever 65 counterclockwise, the pair of pinions 62 coaxially supported by the operation lever 65 rotate, and the pair of pinions 62 The interlocking rack 51a and the rack 51b descend together with the elevating body 60. With the lowering, the connection mounting member 80 is lowered, and the vibration-type electric drill 95 fixed between the fixed-side concave portion 91 and the movable-side concave portion 92 integrally fixed to the connection mounting member 80 is lowered. A mounting hole for attaching the braille base 101 to the square stone 100 by the blade 96 is formed. At this time, the rotational force of the operation lever 65 becomes the pressing force of the drill blade 96. In the connecting portion 61, the bolt 66 as a lowering stopper is clamped between the nut 66a and the nut 66b at a portion parallel to the surface of the third auxiliary table 42, so that the bolt 66 serves as a lowering stopper of the third auxiliary table 42. When contacting the surface, the connecting portion 61
, That is, the descent of the elevating body 60 is stopped, and the drilling depth is determined.

However, since the vibration type electric drill 95 imparts vertical vibration to the drill blade 96 during the drilling operation,
When the tip of the drill blade 96 is made of a hard material such as a stone, the fixed-side concave portion 91 is removed from the main body of the vibration-type electric drill 95.
The vertical vibrations are transmitted to the connection mounting member 80 via the movable side concave portion 92 and the vertical vibrations of the connection mounting member 80 are allowed to move in the vertical direction by the linear bushes 71a and 71b. Vertical movement shafts 72a, 72
b moves up and down. Between the pair of linear bush 71a and the linear bush 71b fixed to the connection attachment member 80 and the connection portion 61, the connection portion 61 and the connection attachment member 80 are connected by coil springs 76a and 76b that apply elastic force in the expansion direction. The vibration is buffered because the space is elastically coupled, and the vibration transmitted to the elevating body 60 is weakened. Therefore, the vibration of the vibration type electric drill 95 is not transmitted to the operation lever 65 as it is. In other words, even if the vibration type electric drill 95 is fixed to the connection mounting member 80 by the clamp mechanism 90, the vibration generated by the vibration type electric drill 95 is absorbed by the coil springs 76a and 76b, and the lifting body 60 and the connection portion Vibration is not transmitted to portions other than 61. That is, the vibration transmitted to the wrist of the worker during the drilling operation can be extremely reduced. The vibration generated by the vibration type electric drill 95 is generated by the coil spring 7.
Since it does not concentrate on specific members other than 6a and 76b, metal fatigue does not occur in the constituent members constituting the drilling device of the present embodiment.

Further, since the cushioning member 15 is provided on the lower surface of the track rail 10, the floor of the square stone material 100 of 40 cm square such as granite, marble, artificial marble, etc., which has been constructed, is not damaged.

1, 25, 26, 35, and 36 can accurately determine the position of the drill blade 96 only by selecting the stop indicators 11, 25, 26, 35, and 36, and can increase work efficiency. In addition, the connecting portion 61, the linear bushes 71a and 71b, the vertical moving shafts 72a and 72b, which allow substantially vertical vibration to the elevating body 60 and elastically couple to substantially vertical vibration.

The buffer holding mechanism including the clamp mechanism 90 buffers the vibration from the fixed vibration-type electric drill 95 with the coil springs 76a and 76b and does not transmit the vibration to a part operated by the operator. The load is reduced, the vibration energy is also buffered by the coil springs 76a and 76b, and no load is applied to a specific component. Therefore, the life of the drilling device including the vibration type electric drill 95 can be extended.
