以上のような従来のタップにおいて、シャンク先端に六角柱状取付軸が形成されたタップは、インパクトドライバー等の正逆回転可能な可搬型電動工具に取り付けて使用され、短時間でねじ穴加工を行うことができる。
しかしながら、被加工部材に形成するねじ穴の数が少なくタップレンチ等の手動工具を用いて手動で操作したい場合等には使用できない。
In the conventional tap as described above, a tap having a hexagonal columnar mounting shaft formed at the tip of the shank is used by being attached to a portable electric tool capable of rotating in the forward and reverse directions such as an impact driver, and performs screw hole processing in a short time. be able to.
However, it cannot be used when the number of screw holes formed in the workpiece is small and it is desired to manually operate it using a manual tool such as a tap wrench.
これに対して、シャンク先端に四角柱状取付軸が形成されたタップは、タップレンチ等の手動工具、又はタッパ等に取り付けて使用できる。
しかしながら、インパクトドライバー等の可搬型電動工具に取り付けて使用できず、生産性向上のために前記可搬型電動工具で使用するためには、特許文献3の電動タップチャックのようなアダプターが必要になる。
On the other hand, a tap having a square columnar attachment shaft formed at the tip of the shank can be used by being attached to a manual tool such as a tap wrench or a tapper.
However, it cannot be used by being attached to a portable electric tool such as an impact driver, and an adapter such as the electric tap chuck of Patent Document 3 is required to use the portable electric tool for improving productivity. .
そこで本考案が前述の状況に鑑み、解決しようとするところは、アダプターを用いずに、インパクトドライバー等の正逆回転可能な可搬型電動工具に取り付けて使用できるとともに、タップレンチ等の手動工具にも取り付けて使用できるタップを提供する点にある。 Therefore, in view of the above situation, the present invention intends to solve the problem by using a portable electric tool such as an impact driver that can be rotated in the forward and reverse directions without using an adapter, and a manual tool such as a tap wrench. The point is to provide a tap that can be attached and used.
本考案の考案者は、前記課題に着目して前記可搬型電動工具及び前記手動工具に兼用可能なタップの形状について鋭意検討を重ね、ねじ部から離間したシャンク先端部に形成した六角柱状取付軸よりも前記ねじ部から遠い端部に、前記六角柱状取付軸の横断面の六角形の外形よりも横断面の外形が小さい四角柱状取付軸を同軸に形成することを想到した。
そして、前記四角柱状取付軸の横断面の外形が前記六角柱状取付軸の横断面の六角形の外形よりも小さいので、前記六角柱状取付軸を前記可搬型電動工具(例えばインパクトドライバー)の六角取付穴に嵌入して装着する際に、前記四角柱状取付軸が干渉することなく装着できるとともに、前記四角柱状取付軸の軸方向長さを標準規格寸法としても干渉しない奥行きが前記六角取付穴にあることを突き止め、本考案を完成するに至った。
The inventor of the present invention pays attention to the above-mentioned problem, and intensively studied the shape of the tap that can be used for both the portable electric tool and the manual tool, and formed a hexagonal columnar mounting shaft formed at the tip of the shank separated from the screw portion. It was conceived that a rectangular columnar mounting shaft having a smaller outer cross-sectional shape than the hexagonal outer shape of the hexagonal columnar mounting shaft is coaxially formed at the end farther from the screw portion.
And since the outer shape of the cross section of the rectangular columnar mounting shaft is smaller than the hexagonal shape of the cross section of the hexagonal columnar mounting shaft, the hexagonal columnar mounting shaft is attached to the hexagonal mounting of the portable electric tool (for example, impact driver). The hexagonal mounting hole has a depth that can be mounted without interfering with the square columnar mounting shaft when fitted into the hole, and does not interfere even if the axial length of the rectangular columnar mounting shaft is a standard standard dimension. As a result, the present invention was completed.
すなわち、本考案に係るタップは、前記課題解決のために、被加工部材にねじ穴加工を行うタップであって、ねじ部から離間したシャンク先端部に、可搬型電動工具の六角取付穴に取り付け可能な六角柱状第1取付軸と、この第1取付軸よりも前記ねじ部から遠い端部に、手動工具の四角取付穴に取り付け可能な四角柱状第2取付軸とを同軸に設けたことを特徴とする。 That is, the tap according to the present invention is a tap for performing a screw hole processing on a workpiece to solve the above-mentioned problem, and is attached to a hexagonal mounting hole of a portable electric tool at a tip of a shank separated from a screw portion. A hexagonal column-shaped first mounting shaft that can be mounted, and a rectangular columnar second mounting shaft that can be mounted in a square mounting hole of a manual tool at the end farther from the threaded portion than the first mounting shaft are provided coaxially. Features.
このような構成によれば、可搬型電動工具に取り付ける際にはシャンク先端部の六角柱状第1取付軸を用い、手動工具に取り付ける際にはシャンク先端部の四角柱状第2取付軸を用いるので、アダプターを用いずに、インパクトドライバー等の正逆回転可能な可搬型電動工具に取り付けて使用できるとともに、タップレンチ等の手動工具にも取り付けて使用できるため、可搬型電動工具用及び手動工具用に別々のタップを備える必要がない。
その上、シャンク先端に四角柱状取付軸が形成された一般規格品であるタップと比較して、切り屑を排出するための溝の深さを浅くして前記可搬型電動工具の使用に合わせた芯厚になっているので、タップレンチ及びT形タップホルダー等の手動工具の四角取付穴に嵌入した状態で使用する際における耐久性が向上する。
According to such a configuration, the hexagonal columnar first mounting shaft at the tip of the shank is used when attaching to the portable power tool, and the square columnar second mounting shaft at the tip of the shank is used when attaching to the manual tool. Because it can be used by attaching to a portable power tool such as an impact driver that can be rotated in the forward and reverse directions without using an adapter, it can also be used by attaching it to a manual tool such as a tap wrench. For portable power tools and manual tools There is no need to have separate taps.
In addition, the depth of the groove for discharging chips is reduced to match the use of the portable electric tool as compared with a tap that is a standard product having a square columnar mounting shaft formed at the tip of the shank. Since it has a core thickness, durability when used in a state of being fitted into a square mounting hole of a manual tool such as a tap wrench or a T-shaped tap holder is improved.
ここで、前記六角柱状第1取付軸が、その軸方向の中間部に、前記可搬型電動工具のワンタッチ取付け機構のボールが係合する周溝が形成されたものであると好ましい。
このような構成によれば、前記作用効果に加えて、ワンタッチで前記可搬型電動工具に取り付けて使用できるので、使用時の利便性が向上する。
Here, it is preferable that the hexagonal columnar first mounting shaft is formed with a circumferential groove that engages with a ball of the one-touch mounting mechanism of the portable electric tool at an intermediate portion in the axial direction.
According to such a configuration, in addition to the above-described effects, it can be used by being attached to the portable electric tool with a single touch, so that convenience during use is improved.
以上のように、本考案に係るタップによれば、アダプターを用いずに、インパクトドライバー等の正逆回転可能な可搬型電動工具に取り付けて使用できるとともに、タップレンチ等の手動工具にも取り付けて使用できるため、可搬型電動工具用及び手動工具用に別々のタップを備える必要がないこと等の顕著な効果を奏する。 As described above, according to the tap according to the present invention, it can be used by attaching it to a portable electric tool that can rotate forward and backward, such as an impact driver, without using an adapter, and it can also be attached to a manual tool such as a tap wrench. Since it can be used, there are significant effects such as no need to provide separate taps for the portable power tool and the manual tool.
