Description

本発明は、手回しねじのノブを回転させる回転治具に関する。 The present invention relates to a rotating jig that rotates a knob of a hand screw.

エレベータや空調機の組立には多くのねじ類が使用されており、メンテナンスの際にはこれらのねじ類の取り付け取り外しを行うことが必要となってくる。ねじ類の頭は規格品の六角形のものや六角穴のものが多く、これらの取り付け取り外しは、規格寸法に合ったレンチ、スパナ等を電動のインパクトレンチ或いは電動ドリルに取り付けて行うことで作業効率を上げている。 Many screws are used for assembling elevators and air conditioners, and it is necessary to attach and remove these screws during maintenance. Many of the screws have standard hexagonal or hexagonal socket heads, and these attachments and removals can be done by attaching a wrench, spanner, etc. suitable for the standard dimensions to an electric impact wrench or electric drill. Increases efficiency.

また、ねじ孔内面の清掃などのように、インパクトレンチや電動ドリルなどに規格品の工具を取り付けたのみでは適切に作業ができない場合には、インパクトレンチや電動ドリルの回転軸とタップ等の他の工具とをアダプタによって接続し、作業効率を上げることが提案されている（例えば、特許文献１参照）。 In addition, if the work cannot be performed properly by simply attaching a standard tool to an impact wrench, electric drill, etc., such as cleaning the inner surface of the screw hole, the rotary shaft and tap of the impact wrench, electric drill, etc. It has been proposed to increase the working efficiency by connecting the tool with an adapter (for example, see Patent Document 1).

ところで、空調機器等のビル設備機器では、点検の回数が多い部位には簡単に開閉できる蓋或いはカバーが取り付けられている場合が多い。このような場合には、スパナや六角レンチなどの工具を用いずに簡単にカバーの取り外しが行えるように、手回しねじによってカバーや蓋をケーシングに固定している。手回しねじのノブは、六角ボルトのような規格品ではなく、人間がつまんで回転させることができる様々な形状をしていることから、これらを規格品の工具によって回転させることができず、分解、開放に時間が掛かってしまう場合があった。 By the way, in building equipment such as an air conditioner, a lid or a cover that can be easily opened and closed is often attached to a part that is frequently checked. In such a case, the cover and the lid are fixed to the casing with a hand screw so that the cover can be easily removed without using a tool such as a spanner or a hexagon wrench. The knob of the hand screw is not a standard product such as a hexagon bolt, but has various shapes that can be pinched and rotated by humans. In some cases, opening takes time.

そこで、本発明は、手回しねじのノブの締め付け、取り外しを高速で行うことを目的とする。 Therefore, an object of the present invention is to fasten and remove a knob of a hand screw at high speed.

図１に示す様に、本実施形態の回転治具１０は、回転工具である電動ドリル２０のチャック２１に把持されるシャフト１２が取り付けられた円板状のベース１１と、ベース１１に取り付けられ、シャフト１２の反対方向に延び、手回しねじ３０のノブ３１を圧縮保持する円筒体１３とを備えている。円筒体１３は、ゴム等の弾性体で、その内形は、ノブ３１の外形よりも僅かに小さく、その先端に軸方向に伸びる複数の切り欠１４と、切り欠き１４の間の保持ツメ１５とを有している。 As shown in FIG. 1, the rotating jig 10 of the present embodiment is attached to the base 11 having a disk-like base 11 to which a shaft 12 held by a chuck 21 of an electric drill 20 that is a rotating tool is attached. The cylindrical body 13 extends in the opposite direction of the shaft 12 and compresses and holds the knob 31 of the hand screw 30. The cylindrical body 13 is an elastic body such as rubber, and its inner shape is slightly smaller than the outer shape of the knob 31, and a plurality of notches 14 extending in the axial direction at the tip thereof and a holding claw 15 between the notches 14. And have.

図２（ａ）に示す様に、シャフト１２は、中心線１７に沿って伸びる金属製の丸棒であり、電動ドリル２０やトルクレンチ等の回転工具のチャック２１で把持することができる程度の直径となっている。ベース１１は金属製或いは、樹脂製の円板であって、その外周面にはゴム等の弾性体の円筒体１３がはめ込まれて固定されている。円筒体１３の内形Ｄは、手回しねじ３０のノブ３１の外形よりも少し小さくなっている。円筒体１３の先端、或いはシャフト１２と反対側には端部からベース１１の方に向かって軸方向に伸びる長方形の切り欠き１４が設けられている。そして、切り欠き１４の間には長方形の保持ツメ１５が形成されている。図２（ｂ）に示す様に、円筒体１３の切り欠き１４は４つであり、保持ツメ１５は５枚となっている。 As shown in FIG. 2A, the shaft 12 is a metal round bar extending along the center line 17 and can be gripped by a chuck 21 of a rotary tool such as an electric drill 20 or a torque wrench. It has a diameter. The base 11 is a metal or resin disk, and a cylindrical body 13 made of an elastic material such as rubber is fitted and fixed to the outer peripheral surface thereof. The inner shape D of the cylindrical body 13 is slightly smaller than the outer shape of the knob 31 of the hand screw 30. A rectangular cutout 14 extending in the axial direction from the end toward the base 11 is provided on the tip of the cylindrical body 13 or on the side opposite to the shaft 12. A rectangular holding claw 15 is formed between the notches 14. As shown in FIG. 2B, the cylindrical body 13 has four notches 14 and the holding claws 15 are five.

図３に示すように、電動ドリル２０のチャック２１に取り付けられた回転治具１０を空調装置のケーシング４０にねじ込まれている手回しねじ３０のノブ３１に向かって押し付けると、図３の一点鎖線で示す様に、各保持ツメ１５の先端はノブ３１の角の丸みに沿ってノブ３１の外周側に向かって広がり、各切り欠き１４は保持ツメ１５の内形が広がるので、その幅が先端に向かって広くなる台形形状に広がっていく。 As shown in FIG. 3, when the rotary jig 10 attached to the chuck 21 of the electric drill 20 is pressed toward the knob 31 of the hand screw 30 screwed into the casing 40 of the air conditioner, a dashed line in FIG. As shown, the tip of each holding claw 15 extends toward the outer periphery of the knob 31 along the rounded corners of the knob 31, and each notch 14 widens the inner shape of the holding claw 15. It spreads in a trapezoidal shape that becomes wider toward you.

円筒体１３はゴム等の弾性体であるので、各保持ツメ１５はノブ３１によって外周側に向かって変形した反力によってノブ３１の外周を締め付け、ノブ３１の外周を圧縮支持する。この状態で、電動ドリル２０を回転させると円筒体１３はノブ３１を圧縮支持した状態で手回しねじ３０を回転させ、手回しねじ３０をケーシング４０から取り外す。また、手回しねじ３０をケーシング４０に取り付ける際には、手回しねじ３０のノブ３１に円筒体１３をはめ込んで円筒体１３に手回しねじ３０のノブ３１を圧縮保持させた状態で、ねじ部３３をケーシング４０に入れて電動ドリルを回転させることによって手回しねじ３０をケーシング４０に取り付けることができる。 Since the cylindrical body 13 is an elastic body such as rubber, each holding claw 15 tightens the outer periphery of the knob 31 by the reaction force deformed toward the outer peripheral side by the knob 31 and compresses and supports the outer periphery of the knob 31. When the electric drill 20 is rotated in this state, the cylindrical body 13 rotates the hand screw 30 with the knob 31 being compressed and supported, and the hand screw 30 is removed from the casing 40. When the hand screw 30 is attached to the casing 40, the cylindrical portion 13 is fitted into the knob 31 of the hand screw 30 and the knob 31 of the hand screw 30 is compressed and held in the cylindrical body 13. The hand screw 30 can be attached to the casing 40 by rotating the electric drill into the casing 40.

以上説明したように、本実施形態の回転治具１０を電動ドリル２０やトルクレンチ等の電動回転工具の先端にセットすることによって、手回しねじ３０のノブ３１の締め付け、取り外しを高速で行うことができる。 As described above, the knob 31 of the hand screw 30 can be fastened and removed at high speed by setting the rotary jig 10 of the present embodiment at the tip of an electric rotary tool such as an electric drill 20 or a torque wrench. it can.

以上説明した実施形態では、長方形で保持ツメ１５により手回しねじ３０のノブ３１の外周を圧縮保持することとして説明したが、保持ツメ１５の一部が図１に示すノブ３１の窪み３２にはまり込むようことができるような幅としてもよい、この場合、保持ツメ１５の半径方向の圧縮力のみでなく保持ツメ１５の側面と窪み３２の係合により手回しねじ３０を回転させる回転トルクを発生させることができ、手回しねじ３０をより強く締め付けたり、締め付けの強い手回しねじ３０を取り外したりすることを容易に行うことができる。また、本実施形態では、筒体は円筒形状の円筒体１３とし、ベース１１は円板状であることとして説明したが、筒体は円筒形である必要はなく六角形、八角形などの多角形筒であり、ベース１１は多角形の板であっても良い。 In the embodiment described above, it has been described that the outer periphery of the knob 31 of the hand screw 30 is compressed and held by the holding claw 15 in a rectangular shape, but a part of the holding claw 15 fits into the recess 32 of the knob 31 shown in FIG. In this case, not only the compression force in the radial direction of the holding claw 15 but also the rotational torque that rotates the hand screw 30 by the engagement of the side surface of the holding claw 15 and the recess 32 is generated. Therefore, it is possible to easily tighten the hand screw 30 and remove the hand screw 30 which is strongly tightened. In the present embodiment, the cylindrical body is the cylindrical cylindrical body 13 and the base 11 is disc-shaped. However, the cylindrical body does not have to be cylindrical, and may be hexagonal, octagonal, or the like. The base 11 may be a polygonal plate.

本実施形態では、切り欠き１４、保持ツメ１５はそれぞれ長方形として説明したが、図４に示す様に、三角形の切り欠き１４ａとし、先端に行くに従って幅が狭くなるような台形形状の保持ツメ１５ａとして構成しても良い。本実施形態は先に説明した実施形態と同様の効果を奏する。 In the present embodiment, the notch 14 and the holding claw 15 are each described as a rectangle, but as shown in FIG. 4, a trapezoidal holding claw 15a having a triangular notch 14a and the width becoming narrower toward the tip. You may comprise as. This embodiment has the same effects as the previously described embodiments.
