This type of drilling tool has a steel or aluminum plate, which is the plate material to be drilled, held between a fixed die and a punch, and penetrates the plate material from the die side to the punch side through a pilot hole in the plate material. By fixing a punch to the threaded part of the rod and driving the rod with a hydraulic cylinder, a component attachment hole larger than the pilot hole, that is, a hole with the diameter of the punch, is drilled in the plate material to be drilled. is as shown in Figure 5.

It is integrally held in the hydraulic cylinder CY. PC
is a punch for drilling that is installed opposite to this die DE,
The inner diameter of the die DE and the outer diameter of the punch PC are set to the desired hole diameter. NL is a rod that penetrates from the die DE side to the punch PC side via the prepared hole SH in the plate material ST to be punched, and its lower end is screwed and fixed to the piston rod PZ in the hydraulic cylinder CY. Then, the punch PC is screwed onto the threaded part of the rod NL at the top, and the punch PC and die are screwed together as shown in the figure.
Rod at the position where DE and plate material to be drilled ST are held together.
Fixed to NL.

The inner hole of the punch has a larger diameter than the rod, and the punch is attached to and removed from the rod by a holding mechanism that holds the punch to the rod. This holding mechanism consists of an engaging part consisting of a screw threaded on the rod or a plurality of annular grooves cut in the axial direction of the rod, a holding ring body having a conical hole concentric with the inner hole, and a holding ring body having a conical hole concentric with the inner hole. When the parts are press-fitted into the conical hole of the annular body, they are mutually screwed into the engaging part of the rod, and when they are released from the press-fitting, they are separated from the engaging part of the rod by an elastic body interposed between them. It is composed of a shaped pawl member and an adjustment ring for operating the press-fitting and evacuation of the split-type pawl member into and out of the conical hole. This adjusting ring also has an inner hole through which the rod can pass, and the split claw member is press-fitted into and removed from the conical hole by being inserted into and removed from the inner hole of the holding ring.

The claw member that is screwed into the engaging portion of the rod is of a split type, and the diameter of the split claw member expands and contracts due to the wedge action of the conical hole. Engagement and attachment to and detachment from the engagement portion are performed. Therefore, there is no need to rotate the pawl member to displace it in the axial direction, and the pawl member can be removed from the rod. By detaching the claw member, the punch can be easily and quickly attached to and detached from the rod.
以下、この発明の好適な実施例を図面を参照し

れている。 Now, the member 3 above the punch 1 is a holding ring having an inner hole larger in diameter than the rod 2, and a conical hole 3T concentrically formed in the inner holes 3H, 3h. As shown in Figure 3. The inner hole 3h is set to have a larger diameter than the threaded portion of the rod 2. One circumferential groove 3M is provided in the upper part, and holes 3N are bored at 120° intervals to ensure good engagement and retention with the adjustment ring 6 inserted into the inner hole 3H as described later. Steel balls 7A to 7C are inserted into this hole 3N. In addition, in FIG. 3, 8 is an O-ring, which functions to prevent the steel balls 7A to 7C from flying outward. In the conical hole 3T portion of the holding ring body 3 shown in FIG.
Split type claw member (nut) 4 (nut 4) shown in
A to 4C) are inserted (press-fitted and removed). That is, first of all, FIG. 4A is a sectional view of the entire split nut taken along plane B-A' in FIG.
This is a cross-sectional view of the right half taken along plane B', and as shown in the figure, the split nut 4 consists of nuts 4A, 4B, and 4C divided into three parts at 120 degrees, and a compression coil interposed between them. (Elastic body) It is an assembly consisting of 5A, 5B, and 5C. The inner cylindrical surface of each of the nuts 4A to 4C of the split nut 4 is formed with a threaded portion 4N that is screwed into the threaded portion of the rod 2. Furthermore, as is clear from the drawings, a conical surface 4T having the same angle as the conical hole 3T of the holding ring 3 is formed on the lower outer periphery of each of the divided bodies 4A to 4C.
このような分割形ナツト４が保持環体３の内孔
３Ｈに嵌挿されるのである。 Such a split nut 4 is inserted into the inner hole 3H of the holding ring 3.

常に維持され、操作される。 Further, the adjustment ring 6 shown in FIG. 2 is inserted into the inner hole 3H of the holding ring 3 from above.
FIG. 1 shows this state. This assembled state is always maintained and operated.
調整環体６には、第２図に示すとおり、保持環

方のＯリング８の付勢力による。 As shown in FIG. 2, the adjustment ring 6 has two grooves 6 in the cylindrical portion inserted into the inner hole 3H of the holding ring 3.
M, 6N are formed. The combination (coupling) of the adjustment ring 6 and the holding ring 3 is maintained by engaging the steel balls 7A to 7C in the holding ring 3 with this one groove 6N. It is by the urging force of the outer O-ring 8 that the steel balls 7A to 7C are maintained in engagement with the inner groove 6N through the hole 3N.
溝６Ｍと６Ｎとの間には、小さい逆向きテーパ

る。 A mountain Y consisting of a combination of small reverse tapers is formed between the grooves 6M and 6N.
This is to facilitate the movement of the steel balls 7A to 7C between the grooves 6M and 6N. This movement of the steel ball is achieved through the inner hole 3H of the holding ring 3 of the adjusting ring 6.
This is done by changing the relative position of the insertion.

易に抜き取ることができる。 That is, as shown on the left side of FIG. 1, when reducing the insertion amount of the adjustment ring 6, the steel balls 7A to 7
C engages with the groove 6N. In this case, since the insertion amount is small, the split nut 4 is expanded by the elasticity of the compression coils 5A to 5C, and the conical hole 3T and the conical surface 4 are expanded.
The upper end of the split nut 4 comes into contact with the lower end surface of the adjustment ring 6 due to the wedge action of the T. In this state, the rod 2 and the split nut 4 are not screwed together, so the entire holding mechanism can be easily removed from the rod 2 as it is.

動させ穿孔動作が行なわれる。 Conversely, when the adjustment ring 6 is further inserted into the inner hole 3H of the holding ring 3, the steel balls 7A to 7C resist the elasticity of the O-ring 8 and move over the mountain Y to the groove 6M, and move to the right side in FIG. It is pushed deeply into the side as shown. Then, the upper end surface of the split nut 4 is pressed downward,
It is shaped to be press-fitted into the conical hole 3T. Then, the split nut 4 is contracted by the action of the wedge against the elasticity of the compression coils 5A to 5C, and its threaded portion 4N is screwed into the threaded portion of the rod 2. Through this screw engagement, the holding mechanism becomes integrated with the rod 2,
When the rod 2 is displaced in the direction of arrow A, the punch 1 is moved to perform a drilling operation.

能である。 The position of the punch 1 on the left side of FIG. 1 shows the position after drilling, but after drilling, by reducing the insertion amount of the adjustment ring 6, the split nut 4 can be placed in the non-press fit state as shown in the figure. shall be. In this state, the holding mechanism can be easily removed in the direction of arrow B.

とすることも可能である。 Although the features of the drilling tool according to the present invention are as described above, the present invention, particularly the holding mechanism, is not limited to the examples described and illustrated above, but includes various modified embodiments. For example, a split nut may be a four-part nut, or if possible, a two-part nut. Furthermore, instead of forming a threaded portion on the rod, the engaging portion of the rod may be formed by forming a plurality of annular grooves in the axial direction of the rod. Furthermore, the mechanism for adjusting the insertion amount of the adjustment ring relative to the holding ring and for holding the position may be constructed using a plate spring or the like other than steel balls and O-rings, and is not limited to the illustrated example.
The rod drive is not limited to a hydraulic system, but can also be a cam mechanism system.
