It has eight inflow ports 24 into which (fluid) flows in and two outflow ports 26 that are provided near the tip of the blade portion 18 and outflow the air in the hollow portion 22.

  When the blade portion 18 forms the hole 21 shown in FIG. 3B in the wood, a gap (concave portion) 19 is formed between the inner wall of the hole 21 and the blade portion 18, and chips are removed from the gap 19 into the hole 21. It has a star-shaped cross section so that it can be discharged outside. Two hollow portions 22 are provided to efficiently send a large amount of air to the outlet 26 of the blade portion 18. In addition, the inner diameters of the two hollow portions 22 are made different in order to make the pressure of the air flowing out from the two outlets 26 different and efficiently discharge large and small chips out of the hole.

  As shown in FIGS. 1 and 2, the rotary drive 16 includes a motor (not shown), a chuck 32 that is rotated by the motor, and a main body 38 that incorporates the motor and rotatably supports the chuck 32.

  Two sealing members 55 are fixed to the shank support portion 42 with screws or the like, and the gap 52 is closed. The shank 20 rotates and slides with respect to the sealing member 55.

  When drilling a hole at the center (fixed position) of a square member (workpiece member) having a square cross section using the drill mounting jig 10, the drill device forming mechanism 11, and the drill device 12 configured as described above, for example, FIG. The drill guide 60 shown in FIG. The square bar may have a cross section such as a rectangle or a circle.

  The drill guide 60 is cylindrical (substantially cylindrical) and guides in the center of a square member 64 processed by the gun drill 14 and a guide member 62 that guides in the longitudinal direction of the blade portion 18 through the blade portion 18 of the gun drill 14. Positioning means 65 for positioning 62. The positioning means 65 is composed of a support plate 66 that supports the guide member 62 at the center, and four hanging plates 70 that are suspended from the support plate 66 and are fixed in contact with the side walls 68 of the square members 64. Yes. The hanging plate 70 is provided with a fixing hole 72 and is fixed to the side wall 68 by screwing a bolt 74 into the fixing hole 72 and pressing the side wall 68 with the tip of the bolt 74.

  The effects of the drill mounting jig 10, the drill device forming mechanism 11, and the drill device 12 having the above-described configuration will be described below.

  First, as shown in FIGS. 4 and 6, the shank 20 of the gun drill 14 is fixed to the drill fixing portion 28 of the drill fixing tool 36, and the chuck fixing portion 34 of the drill fixing tool 36 is fixed to the chuck of the commercially available rotary drive machine 16. By fixing to 32, the gun drill 14 is fixed to the chuck 32 of the rotary drive machine 16. Moreover, the main body fixing part 40 of the main body connecting tool 48 is fixed to the rotary drive 16, and the shank 20 of the gun drill 14 is rotatably supported by the shank support part 42 of the main body connecting tool 48, whereby the gun drill 14 is supported by the shank support part. The gun drill 14 is connected to the main body 38 of the rotary driving machine 16 so as to be rotatable with respect to 42 and to allow air to flow into the inlet 24 of the shank 20.

  Thereby, the drill device 12 including the gun drill 14 can be configured by a commercially available rotary drive 16. This eliminates the need for a rotary drive dedicated to the gun drill and reduces the manufacturing cost of the drill device. Moreover, since the drill apparatus 12 including the gun drill 14 can be configured by a commercially available rotary drive machine 16 that is familiar to the user, the drill apparatus can be easily handled.

  Further, since the shank 20 of the gun drill 14 is provided with an inflow port or the like and is larger (thick) than a normal shank of a drill, it cannot be attached to the chuck 32 of the commercially available rotary drive machine 16 as it is. However, according to the present invention, the shank 20 can be attached to the chuck 32 of the commercially available rotary drive 16 by the drill fixture 36 having the drill fixture 28 and the chuck fixture 34.

  The following describes the operation and effect when the hole is formed at the center of the square member 64 shown in FIG. 5 using the drill mounting jig 10, the drill device forming mechanism 11, the drill device 12, and the drill guide 60 configured as described above. To do.

  First, as shown in FIGS. 5 and 6, the four guide plates 70 are brought into contact with the side wall 68 of the square member 64 and fixed by the bolts 74, thereby fixing the drill guide 60 to the square member 64.

  The operator holds the drill device 12 and causes the gun drill 14 to penetrate the guide member 62 of the drill guide 60 as shown in FIGS. 5 and 6. Next, the rotary drive 16 is driven to rotate the gun drill 14. The operator applies a force in a direction in which the drill device 12 is moved downward along the guide member 62, so that a hole is formed at the center of the square member 64.

  Further, a pneumatic pump (not shown) is driven to send compressed air from the pipe 44 to the gap 52 shown in FIG. The compressed air sent to the gap 52 enters the hollow portion 22 shown in FIG. 3 from the inflow port 24 and flows out from the outflow port 26. When the compressed air flows out from the outlet 26, the compressed air flows from the vicinity of the tip of the blade portion 18 toward the inlet of the hole formed in the square member 64, and the compressed air is generated in the chips generated in the gap between the hole and the gun drill 14. It is applied and chips can be discharged out of the hole through the gap.

  When the square member 64 having a hole at the center is formed in this way, a reinforcing bar is inserted into the hole, and a square member having a reinforcing bar at the center is formed.

  When the length of the square member 64 is longer than that of the gun drill 14, a hole is formed in the same manner from the opposite side. According to the present invention, since a hole can be formed accurately and straightly at the center of a square bar, the holes are connected to one.
