Abstract

PURPOSE:To break a collar with a predetermined force to prevent a machine and a drill from breakaging by providing a notch between a main body and a collar while a drill holder is divided into three and the free end thereof can be opened and closed. CONSTITUTION:A drill holder 3 is mounted on a base 1 and provided with a tapered hole 7 flaring upward, a projection 8 on an end of this tapered hole and a large diameter hole 9. Also, the holder 6 is divided into three circumferentially so that the free end is liable to expand. Further, a main body 4 is provided with a small diameter hole 11 and a notch 10 between the hole 11 and a collar 5. Also, a collar 15 fitted in the hole 9 is press fitted onto a drill 14. Thus, when the drill 14 onto which the collar is press fitted is forced into the holder 3 and further forced therin until a spring is completely compressed, the collar 5 is broken down to drop the holder and prevent a machine and the drill from breakage.

高価なものになる欠点がある。For drilling printed circuit boards, a drill holding device for holding a drill for the purpose of replacing the drill is known, for example, as disclosed in US Pat. No. 3,973,863. This drill holding device is designed so that when excessive force is applied in the axial direction of the drill, the bottom of the drill holding device can be destroyed to prevent damage to the machine or the drill. However, the drill holding device has the disadvantage that it has a large number of parts, requires a lot of time and effort to process and assemble them, and is expensive.

嵌合するカラー１５が圧入されている。1 to 4 show an embodiment of the present invention, and in the figures, a drill holding device 3 is supported in a hole 2 formed in a base 1 fixed to a machine. This drill holding device 3 consists of a large diameter main body 4 that fits into the hole 2, a collar 5 projecting from the main body 4, and a holding portion 6 projecting from the main body 4. The holding portion 6 has a tapered hole 7 that widens toward the open end, a protrusion 8 formed at one end of the tapered hole 7, and a large diameter hole 9 that communicates with the tapered hole 7. . Further, the holding portion 6 is divided into three parts in the circumferential direction, and the free end is a trap that can be opened and closed. A notch 10 is formed between the main body 4 and the flange 5, so that the main body 4 and the flange 5 can be broken by a predetermined force. A small diameter hole 11 communicating with the hole 9 is formed in the main body 4 . The steps 12 of the holes 9 and 11 support a spring 13 inserted in the hole 9. A collar 15 that fits into the hole 9 is press-fitted into the drill 14.

態で保持される。With the above configuration, when the drill 14 into which the collar 15 is press-fitted is pushed through the tapered hole 6, the collar 15 expands the holding portion 6 and enters the hole 9. At this time, the collar 15 is connected to the spring 1
Press 3 to compress. When the drill 14 is released in this state, the upper end surface of the collar 15 is held in contact with the lower end surface of the projection 8.
