2. Description of the Related Art Generally, in the stone processing industry, a small electric cutting tool is used when processing curved surfaces such as tower-shaped shades and cutting and polishing small stones such as the curved surface of a parent pillar or the edge of an outer fence. After carrying it in a hand and cutting it into a predetermined shape, a small electric polishing tool or an air polishing tool is held in the hand and the cutting surface is polished to perform finishing. Also, when performing drilling, similarly, a small electric drilling tool is held in the hand and drilling is performed at a predetermined position on the stone material.

As described above, when a small stone material is processed, a small rotary tool driven by electric power or air is held in the hand, and the work becomes heavy work.

The disk part 36 is attached between the back plates 38 of the frame 37 so as to sandwich the disk part 36 from both sides. It is rotatably connected by a shaft 39. Also, one rear plate 38 has a pin hole as shown in FIG.
Is detachably provided, and this is an arbitrary pin hole of the disc portion 36.
By fitting the frame 37 to the frame 37, the frame 37 can be set in the front-rear direction at a predetermined angle.

As shown in FIG. 3, two guide shafts 42, 42 are vertically mounted on the front surface of the frame 37, and these guide shafts 42 penetrate the elevating block 43. The coil spring 30 is attached to one guide shaft 42 between the bottom surface of the elevating block 43 and the bottom plate of the frame 37, and is configured to support the elevating block 43 at all times so as to be elastically movable upward and downward. . Further, a rack 44 is attached to the rear side of the elevating block 43, which engages with a pinion 46 attached to a rotary shaft 45 penetrating the frame 37 in the lateral direction to rotate a lever 47 attached to the rotary shaft 45. By doing so, the elevating block 43 is moved up and down.

A screw groove 48 is formed on the front surface of the elevating block 43 to form a second attaching / detaching mechanism 50. Further, as shown in FIG. 6, a stopper ring 51 is attached to the other guide shaft 42 penetrating the elevating block 43, and by fixing this to an arbitrary height of the guide shaft 42, the lowering position of the elevating block 43 can be set. It is supposed to be set. Reference numeral 52 is a lock mechanism attached to the side surface of the lifting block 43.

Further, the cutting device 33 has a structure in which an electric cutting tool 56 is attached to a support frame 55 connected to a guide frame 54 as shown in phantom in FIG.

Therefore, when changing the set angle of the cutting device 33, the lock pin 40 of the rotary lifting mechanism 34 is pulled out from the state shown in FIG. 3, the angle of the frame 37 is changed, and the lock pin 40 is pin holed at a predetermined angle. When it is fitted into the lock 35 and locked, the cutting device 33 can be rotated to cause the rotary blade 60 of the cutting tool 56 to face upward, for example, as shown in FIG.

As shown in FIG. 7, the top plate of the washbasin is
In the case where the center of a plate-shaped stone material 61 is hollowed out to be processed into an elliptical shape, conventionally, a two-divided structure is used, and two pieces cut from a side surface into a U shape are combined. However, in the cutting device 33 of the present invention, the height of the stopper ring 51 attached to the guide shaft 42 shown in FIG. 6 is set so that the lower portion of the rotary blade 60 attached to the cutting tool 56 matches the bottom surface of the stone material 61. When the lever 47 is lowered from, the cutting tool 56 descends and the rotary blade 60 cuts the stone material 61 from the upper surface side.

When the elevating block 43 of the rotating elevating mechanism 34 hits the stopper ring 51, the lowering of the rotary blade 60 is stopped, so the lever 47 is raised and the position of the cutting tool 56 is moved. Then, while pressing down the lever 47 again, as shown in FIG. 7, the short linear groove 62 is processed to form an elliptical shape as a whole. After that, the elliptical portion is removed, and then the cut surface is polished and finished. In this way, since the descending height of the rotary blade 60 can be set, it is possible to form a short linear groove 62 at the lower blade edge and combine this to form an oval hole from a single stone 61.

In addition, as shown in FIG. 9, a plate-shaped stone material 61
When drilling in a circular shape, the electric drill 66 can be lowered while pushing down the lever 47, and can be moved in the plane direction by the arm 2. Therefore, the circular hole 67 can be sequentially moved while moving above the stone 61.
A circular hole can be formed by processing the material into a circular shape and then hollowing it out.

When changing the angle of the electric drill 66,
The lock pin 40 of the rotary lifting mechanism 34 shown in FIG. 8 is pulled out, the angle of the frame 37 is changed, and the lock pin 40 is rotated at a predetermined angle.
When the 40 is fitted into the pin hole 35 and locked, the electric drill 66 can be set at a predetermined angle, and for example, a side surface of a stone material can be easily drilled.

In the above embodiment, the case where the polishing device is attached to the first attaching / detaching mechanism has been described, but a cutting device or a drilling device may be attached. In the above embodiment, the case where the electric rotary tool is attached has been described, but an air driven tool may be used. Further, the arm 2 is the base end side arm member 2
Although the case where it is formed by two members of A and the tip side arm member 2B is shown, a bent structure in which three or more members are connected may be used.
