Description

この発明は、部材の締付け時において、ボルト、ナット、及び座金等の共回りを防止すべく、ボルト孔周囲の表面に粗面を形成するための切削工具、及び該切削工具を用いた部材の粗面形成方法に関する。   The present invention relates to a cutting tool for forming a rough surface on a surface around a bolt hole and a member using the cutting tool so as to prevent co-rotation of bolts, nuts, washers, and the like when the member is tightened. The present invention relates to a rough surface forming method.

従来、例えば、図8に示すように、2つの部材101a、部材101bを連結する際には、ボルト102のボルト頭102aと部材101bとの間、及びナット103と部材101aとの間にそれぞれ座金104を介在させ、図9に示すように、ボルト102とナット103を螺合することで、これらを連結している。しかし、前述の方法では、部材101a、及び部材101bのそれぞれの表面と座金104との摩擦力が小さく、螺合する際に、ボルト102、ナット103、及び、座金104が図9に示す矢印Aのように共回りするという問題が生じる。このような問題は、部材101a、部材101bの表面が研磨されていたり、該表面に塗装、若しくはメッキ等が施されている場合には特に顕著である。そして、共回りが発生すると、そのままでは締付けができないので、一旦ボルト102からナット103を緩めて再度ボルト102をナット103に螺合する必要がある。しかし、高力ボルトを使用する場合等には、高力ボルトの耐力の観点から当該高力ボルトを緩めてそれを再使用することができず、これを処分する必要があるため経済的に好ましくないという問題がある。さらに、このようなやり直しの作業を余分に行う必要があるため、作業効率が低下するという問題がある。そのため、以下に示すような共回り防止座金が考案されている。   Conventionally, for example, as shown in FIG. 8, when two members 101a and 101b are connected, washers are provided between the bolt head 102a and the member 101b of the bolt 102 and between the nut 103 and the member 101a. As shown in FIG. 9, the bolt 102 and the nut 103 are screwed together so as to connect them. However, in the above-described method, the frictional force between the respective surfaces of the members 101a and 101b and the washer 104 is small, and the bolt 102, the nut 103, and the washer 104 are shown by the arrow A in FIG. The problem of co-rotation occurs. Such a problem is particularly prominent when the surfaces of the members 101a and 101b are polished or coated or plated. When the joint rotation occurs, it cannot be tightened as it is, so it is necessary to once loosen the nut 103 from the bolt 102 and screw the bolt 102 to the nut 103 again. However, when a high strength bolt is used, it is economically preferable because the high strength bolt cannot be loosened and reused from the viewpoint of the proof strength of the high strength bolt and must be disposed of. There is no problem. Furthermore, since it is necessary to perform such an extra work, there is a problem that work efficiency is lowered. For this reason, the following joint washer has been devised.

この共回り防止座金200は、図10に示すように、被取付部材201を固着するネジ部品202の締付け面203と前記被取付部材201との間に設けられる共回り防止座金200において、前記ネジ部品202の締付け面203に面接触する面に低摩擦係数の塗膜204が被着され、その反対側面には溝205が形成されたものである(例えば、特許文献1)。   As shown in FIG. 10, the common rotation preventing washer 200 is the same as the common rotation prevention washer 200 provided between the tightening surface 203 of the screw component 202 to which the member to be attached 201 is fixed and the member to be attached 201. A coating 204 having a low friction coefficient is applied to the surface of the component 202 that is in surface contact with the tightening surface 203, and a groove 205 is formed on the opposite side surface (for example, Patent Document 1).

実開平04−49217号公報Japanese Utility Model Publication No. 04-49217

しかし、前述の共回り防止座金200を作成する際には、フッ素樹脂系の塗膜204を被着させ、溝205を形成する等の手間がかかるため、該共回り防止座金200の価格が高くなり、結果として施工費用が高くなるという問題がある。   However, when preparing the above-described common-turn prevention washer 200, it takes time and effort to deposit the fluororesin-based coating film 204 and form the groove 205, and the cost of the common-turn prevention washer 200 is high. As a result, there is a problem that the construction cost becomes high.

この発明は上記のような種々の課題を解決することを目的としてなされたものであって、ボルト、ナット、及び座金等の共回りを防止すべく、ボルト孔周囲の表面に粗面を形成するための切削工具、及び該切削工具を用いた部材の粗面形成方法に関する。   The present invention has been made for the purpose of solving the various problems as described above, and forms a rough surface on the surface around the bolt hole in order to prevent co-rotation of bolts, nuts, washers, and the like. TECHNICAL FIELD The present invention relates to a cutting tool for forming a rough surface of a member using the cutting tool.

上記目的を達成するために、請求項1記載の切削工具は、回転式切削機の回転部にその一端側が着脱自在に取付けられる円柱状の軸部と、該軸部の他端側に連続して形成され、その先端側面に削り面を具備する削り部と、該削り部の削り面の中心部に連続して形成される円柱状のガイド部と、を具備することを特徴としている。   In order to achieve the above object, a cutting tool according to claim 1 is provided such that a cylindrical shaft portion whose one end side is detachably attached to a rotating portion of a rotary cutting machine, and a second end side of the shaft portion. And a cylindrical guide portion formed continuously from the central portion of the shaving surface of the shaving portion.

請求項2記載の切削工具は、前記ガイド部が先端方向に向かって先細るようにテーパー状に形成されていることを特徴としている。   The cutting tool according to a second aspect is characterized in that the guide portion is formed in a taper shape so as to taper in the distal direction.

請求項3記載の切削工具を用いた部材の粗面形成方法は、請求項1又は2記載の切削工具を用いて、部材に形成されたボルト孔周囲の表面に粗面を形成することを特徴としている。   A method for forming a rough surface of a member using the cutting tool according to claim 3 is characterized in that a rough surface is formed on a surface around a bolt hole formed in the member using the cutting tool according to claim 1 or 2. It is said.

請求項4記載の切削工具を用いた部材の粗面形成方法は、前記ボルト孔周囲の表面に形成された粗面の径が、ボルト頭、ナット、若しくはこれらと前記部材との間に介在される円盤状の座金よりも小径であることを特徴としている。   The method for forming a rough surface of a member using the cutting tool according to claim 4, wherein a diameter of the rough surface formed on a surface around the bolt hole is interposed between a bolt head, a nut, or these and the member. It is characterized by a smaller diameter than a disc-shaped washer.

請求項1記載の切削工具によれば、回転式切削機の回転部に着脱自在の軸部を具備している。そのため、汎用性の高いボール盤や、電気ドリル等にも取付けることができるので、既存の設備をそのまま利用することができ経済的である。さらに、削り部の削り面に連続して形成される円柱状のガイド部を具備している。そのため、ガイド部を、部材に形成されたボルト孔に挿入してから回転式切削機の回転部を回転させることで、削り部に形成された削り面によってボルト孔周囲の部材表面を同心円状に荒し、当該箇所に摩擦抵抗の大きい粗面を形成することができる。これにより、部材と直接接触するボルト頭、ナット、若しくは、座金等との摩擦力が向上するため、これらを螺合する際にも共回りが発生することがなく、また、螺合した後も緩み難いという利点がある。従って、高力ボルトを使用する場合にも、該高力ボルトの締め直しを行う必要がなく該高力ボルトの浪費を抑えることができ経済的であり、さらに、締め直しの作業自体を行う必要がないので作業効率を向上することができる。   According to the cutting tool of the first aspect, the rotary part of the rotary cutting machine has the detachable shaft part. Therefore, since it can be attached to a versatile drilling machine, an electric drill or the like, the existing equipment can be used as it is, which is economical. Furthermore, a cylindrical guide part formed continuously on the shaving surface of the shaving part is provided. Therefore, by inserting the guide part into the bolt hole formed in the member and then rotating the rotating part of the rotary cutting machine, the surface of the member around the bolt hole is concentrically formed by the cutting surface formed in the cutting part. A rough surface having a large frictional resistance can be formed in the rough portion. As a result, the frictional force with the bolt head, nut, or washer that is in direct contact with the member is improved, so there is no co-rotation when these are screwed together, and after screwing There is an advantage that it is difficult to loosen. Therefore, even when a high-strength bolt is used, it is not necessary to retighten the high-strength bolt, so that waste of the high-strength bolt can be suppressed, and it is economical, and further, the retightening operation itself needs to be performed. Since there is no, work efficiency can be improved.

請求項2記載の切削工具によれば、ガイド部が先端方向に向かって先細るようにテーパー状に形成されている。そのため、ガイド部の先端部をボルト孔に容易に挿入することができるという利点がある。   According to the cutting tool of the second aspect, the guide portion is formed in a taper shape so as to taper in the distal direction. Therefore, there exists an advantage that the front-end | tip part of a guide part can be easily inserted in a bolt hole.

請求項3記載の切削工具を用いた部材の粗面形成方法は、請求項1又は2記載の切削工具を用いて、部材に形成されたボルト孔周囲の表面に粗面を形成する方法である。この方法によると、部材表面が研磨され、または、該表面に塗装やメッキが施される等の表面加工がなされていたとしても、摩擦抵抗の大きい粗面を形成することで該部材表面とボルト頭、ナット、及び座金等との間の摩擦力を向上させることができ、共回りの発生を抑制することができる。このため、部材のボルト孔周囲の表面だけ表面加工を行わない、というような複雑な表面加工方法を採用する必要がない。また、汎用の電着塗装で部材全体に塗装したとしても、容易にボルト孔周囲の表面だけを荒らし、該塗装を剥離することができるので作業が効率的である。   A method for forming a rough surface of a member using the cutting tool according to claim 3 is a method for forming a rough surface on a surface around a bolt hole formed in the member using the cutting tool according to claim 1 or 2. . According to this method, even if the surface of the member is polished or surface treatment such as coating or plating is performed on the surface, the surface of the member and the bolt are formed by forming a rough surface having a high frictional resistance. The frictional force between the head, nut, washer and the like can be improved, and the occurrence of co-rotation can be suppressed. For this reason, it is not necessary to employ a complicated surface processing method in which the surface processing is not performed only on the surface around the bolt hole of the member. Further, even if the entire member is coated by general-purpose electrodeposition coating, only the surface around the bolt hole can be easily roughed and the coating can be peeled off, so that the operation is efficient.

請求項4記載の切削工具を用いた部材の粗面形成方法によれば、ボルト孔周囲の表面に形成された粗面の径が、ボルト頭、ナット、若しくはこれらと部材との間に介在される円盤状の座金よりも小径である。そのため、ボルトとナットを螺合した後は、ボルト孔周囲に形成された粗面が、座金、若しくは座金を使用しない場合においてもボルト頭、若しくはナットによって覆われるため、当該粗面が外見上視認できず、外観を損なうことがないという利点がある。   According to the method for forming a rough surface of a member using the cutting tool according to claim 4, the diameter of the rough surface formed on the surface around the bolt hole is interposed between the bolt head, the nut, or these and the member. The diameter is smaller than the disc-shaped washer. Therefore, after the bolt and nut are screwed together, the rough surface formed around the bolt hole is covered with the bolt head or nut even when the washer or washer is not used. There is an advantage that it cannot be performed and the appearance is not impaired.

この発明における切削工具の最良の実施形態について、以下に説明する。本発明に係る切削工具1は、図1、図2、及び図3に示すように、回転式切削機2の回転部3にその一端側が着脱自在に取付けられる円柱状の軸部4と、該軸部4の他端側に連続して形成され、その先端側面に削り溝5が形成された削り面6を具備する削り部7と、該削り部7の削り面6の中心部に連続して形成され、部材8に形成されたボルト孔9に挿脱自在な円柱状のガイド部10と、を具備している。そして、軸部4、削り部7、及びガイド部10は、図1、及び図2に示すように、同軸状に形成されている。   The best embodiment of the cutting tool in this invention is described below. A cutting tool 1 according to the present invention includes, as shown in FIGS. 1, 2, and 3, a cylindrical shaft portion 4 having one end side detachably attached to a rotating portion 3 of a rotary cutting machine 2, A shaving portion 7 having a shaving surface 6 formed continuously on the other end side of the shaft portion 4 and having a shaving groove 5 formed on the tip side surface thereof, and a center portion of the shaving surface 6 of the shaving portion 7 is continuous. And a columnar guide portion 10 that can be inserted into and removed from a bolt hole 9 formed in the member 8. The shaft portion 4, the shaving portion 7, and the guide portion 10 are formed coaxially as shown in FIGS.

前記軸部4は、回転式切削機2の回転部3のチャック11にその一端側が着脱自在に取付けられる円柱状の鋼製の部材である。回転式切削機2は、回転部3を具備し、手動、若しくは、電動で当該回転部3を回転させることのできるボール盤や、電気ドリル等であって、該回転部3にドリルや、研磨用のディスク、ドライバー、レンチ等を着脱自在なチャック11を具備している。そして、本実施形態においては、図3に示すように、商業用電源を使用せずとも駆動可能な、バッテリーVを具備する汎用の電気ドリルを使用している。   The shaft portion 4 is a columnar steel member whose one end is detachably attached to the chuck 11 of the rotating portion 3 of the rotary cutting machine 2. The rotary cutting machine 2 includes a rotating part 3 and is a drilling machine, an electric drill, or the like that can rotate the rotating part 3 manually or electrically. A chuck 11 on which a disk, a driver, a wrench and the like can be freely attached and detached is provided. And in this embodiment, as shown in FIG. 3, the general purpose electric drill which comprises the battery V which can be driven without using a commercial power source is used.

そして、本実施形態に係る切削工具1おいては、図1、図2、及び図3に示すように、回転部3のチャック11に取付けられる軸部4の一端側に溝12が形成されており、該チャック11に挟持された際に、作業者の意に反して該チャック11から軸部4が離脱することのないようになっている。   And in the cutting tool 1 which concerns on this embodiment, as shown in FIG.1, FIG.2, and FIG.3, the groove | channel 12 is formed in the one end side of the axial part 4 attached to the chuck | zipper 11 of the rotation part 3. As shown in FIG. Thus, the shaft 4 is prevented from being detached from the chuck 11 against the operator's will when sandwiched by the chuck 11.

前記削り部7は、軸部4の他端側、すなわち、チャック11に取付けられる側と反対側に該軸部4と同軸状に円柱状に連続して形成され、部材8の表面Fを荒し、粗面13を形成するための鋼製の部材である。そして、円柱状に形成された削り部7の先端側面、すなわち、部材8の表面Fと接触する側の面には、図1に示すように、該先端側面の中心から放射状に削り溝5を形成した削り面6が形成されている。   The shaving portion 7 is continuously formed in a cylindrical shape coaxially with the shaft portion 4 on the other end side of the shaft portion 4, that is, the side opposite to the side attached to the chuck 11, and roughens the surface F of the member 8. A steel member for forming the rough surface 13. Then, on the tip side surface of the shaving portion 7 formed in a columnar shape, that is, the surface in contact with the surface F of the member 8, as shown in FIG. 1, the shaving grooves 5 are formed radially from the center of the tip side surface. The formed shaving surface 6 is formed.

また、図2に示すように、他の実施形態に係る切削工具1においては、削り部7は、軸部4の他端側に連続して形成され、且つ、該軸部4と同軸状に四角柱状に形成されている。そして、四角柱状に形成された削り部7の先端側面、すなわち、部材8の表面Fと接触する側の面は、図2に示すように、網目状の削り溝5を形成した削り面6となっている。以上のように削り部7が形成されているので、部材8に形成されたボルト孔9の周囲の表面Fを均一に荒らし、該表面Fに摩擦抵抗の大きい粗面13を形成することができるのである。また、削り部7の形状、及び削り面6に形成される削り溝5の形状は上述のような形状に限定されるわけではなく、適宜変更することができるのは勿論である。   As shown in FIG. 2, in the cutting tool 1 according to another embodiment, the shaving portion 7 is continuously formed on the other end side of the shaft portion 4 and is coaxial with the shaft portion 4. It is formed in a quadrangular prism shape. Then, the tip side surface of the shaving portion 7 formed in the shape of a quadrangular prism, that is, the surface on the side in contact with the surface F of the member 8, as shown in FIG. 2, is a shaving surface 6 in which a mesh-like shaving groove 5 is formed. It has become. Since the shaving portion 7 is formed as described above, the surface F around the bolt hole 9 formed in the member 8 can be uniformly roughened, and the rough surface 13 having high frictional resistance can be formed on the surface F. It is. Further, the shape of the shaving portion 7 and the shape of the shaving groove 5 formed on the shaving surface 6 are not limited to the shapes as described above, and can be changed as appropriate.

前記ガイド部10は、前記削り部7に形成された削り面6の中心部に同軸状に連続して形成された円柱状の鋼製の部材である。使用時には、図3に示すように、部材8のボルト孔9にガイド部10を挿入して回転式切削機2の回転部3を駆動させた際に、このガイド部10によって同心円状に回転できる。また、該ガイド部10の径は該ボルト孔9よりも、例えば5mm程度小さく形成されていることが好ましい。これにより、図4、図5及び図6に示すように、ボルト孔9の周囲に同心円状に部材8の表面Fを荒らし、摩擦抵抗の大きい粗面13を形成することができる。さらに、ガイド部10は、図1、及び図2に示すように、その先端方向に向かって先細るようにテーパー状に形成されているので、図3に示すように、ガイド部10をボルト孔9への挿入が容易なものとなる。また、このガイド部10の長さや、テーパー角は、目的に応じて適宜変更することができる。   The guide portion 10 is a cylindrical steel member formed continuously in a coaxial manner at the center portion of the shaving surface 6 formed in the shaving portion 7. In use, as shown in FIG. 3, when the guide portion 10 is inserted into the bolt hole 9 of the member 8 and the rotating portion 3 of the rotary cutting machine 2 is driven, the guide portion 10 can rotate concentrically. . The diameter of the guide portion 10 is preferably smaller than the bolt hole 9 by, for example, about 5 mm. As a result, as shown in FIGS. 4, 5, and 6, the surface F of the member 8 can be roughened concentrically around the bolt hole 9, and a rough surface 13 having a high frictional resistance can be formed. Further, as shown in FIG. 1 and FIG. 2, the guide portion 10 is formed in a taper shape so as to taper toward the distal end thereof, so that the guide portion 10 is formed with a bolt hole as shown in FIG. 9 can be easily inserted. Further, the length and taper angle of the guide portion 10 can be appropriately changed according to the purpose.

以上のように構成される切削工具1を用いた部材の粗面形成方法について以下に説明する。   A method for forming a rough surface of a member using the cutting tool 1 configured as described above will be described below.

まず、図1、若しくは、図2に示すように構成される切削工具1を、回転式切削機2としての電気ドリルの回転部3のチャック11に取付ける。そして、図3に示すように、例えば表面Fに電着塗装14が施されている部材8に形成されたボルト孔9に、ガイド部10を挿入する。   First, the cutting tool 1 configured as shown in FIG. 1 or FIG. 2 is attached to the chuck 11 of the rotating part 3 of the electric drill as the rotary cutting machine 2. And as shown in FIG. 3, the guide part 10 is inserted in the bolt hole 9 formed in the member 8 by which the electrodeposition coating 14 is given to the surface F, for example.

そして、削り部7の削り面6を部材8の表面Fに軽く押付けるようにして、電気ドリルのスイッチ15を入れ、回転部3を駆動させる。これにより、削り部7の削り面6によって、部材8に形成されたボルト孔9の周囲の表面Fが荒らされ、該部材8に施された塗装14が剥離され摩擦抵抗の大きい粗面13が形成されるのである。このとき、粗面13の径が、座金16の径よりも小さければ、図7に示すように、ボルト17やナット18を締め終えた後に、粗面13が座金16によって覆われるため外観を損なうことがない。図1に示す実施形態に係る切削工具1は、円柱状の削り部7の削り面6の径が、使用される座金16の径よりも小さくなるように形成されているのはこのためである。   Then, the shaving surface 6 of the shaving portion 7 is lightly pressed against the surface F of the member 8, the switch 15 of the electric drill is turned on, and the rotating portion 3 is driven. As a result, the surface F around the bolt hole 9 formed in the member 8 is roughened by the shaving surface 6 of the shaving portion 7, and the coating 14 applied to the member 8 is peeled off to form a rough surface 13 having a high frictional resistance. It is formed. At this time, if the diameter of the rough surface 13 is smaller than the diameter of the washer 16, the outer surface is damaged because the rough surface 13 is covered with the washer 16 after the bolt 17 and the nut 18 are tightened as shown in FIG. There is nothing. This is why the cutting tool 1 according to the embodiment shown in FIG. 1 is formed such that the diameter of the cutting surface 6 of the cylindrical cutting portion 7 is smaller than the diameter of the washer 16 used. .

また、図2に示すその他の実施形態に係る切削工具1は、四角柱状の削り部7の削り面6の対角線の長さが、使用される座金16の径よりも小さくなるように形成されている。さらに、図5に示すように、部材8aと部材8bとを連結する場合において座金16を使用しない場合には、図1に示す円柱状の削り部7の削り面6の径、及び図2に示す四角柱状の削り部7の削り面6の対角線の長さが、ボルト頭17a、及びナット18の径よりも小さくなるように形成することで、上述のように仕上がり後の外観を損なうことがないようにしている。   In addition, the cutting tool 1 according to another embodiment shown in FIG. 2 is formed such that the length of the diagonal line of the cutting surface 6 of the square columnar cutting portion 7 is smaller than the diameter of the washer 16 used. Yes. Further, as shown in FIG. 5, when the member 8a and the member 8b are connected, when the washer 16 is not used, the diameter of the cutting surface 6 of the cylindrical cutting portion 7 shown in FIG. By forming the diagonal line of the cut surface 6 of the square columnar cut portion 7 shown to be smaller than the diameters of the bolt head 17a and the nut 18, the appearance after finishing may be impaired as described above. I am trying not to.

また、図4に示すように、部材8a、部材8bの両側からボルト17とナット18により部材8同士を連結する場合には、部材8aと部材8bの両方のボルト孔9の周囲の表面Fが荒らされた粗面13が形成されることが、ボルト17、ナット18、及び座金16の共回りと共に緩みを防止するという観点から好ましい。しかし、部材8aと部材8bのどちらか一方のボルト孔9の周囲の表面Fが荒らされ、粗面13が形成されていれば、ボルト17、ナット18、及び座金16の共回りを防止する効果を得ることができる。   As shown in FIG. 4, when the members 8 are connected to each other by bolts 17 and nuts 18 from both sides of the members 8a and 8b, the surface F around the bolt holes 9 of both the members 8a and 8b is It is preferable that the roughened rough surface 13 is formed from the viewpoint of preventing looseness together with the rotation of the bolt 17, the nut 18, and the washer 16. However, if the surface F around the bolt hole 9 of either the member 8a or the member 8b is roughened and the rough surface 13 is formed, the effect of preventing the bolt 17, the nut 18, and the washer 16 from rotating together. Can be obtained.

そして、図6に示すように、例えば所定厚みを有し、ネジ穴19が形成された部材Xに、板状の部材8cを固定する場合には、該部材Xと接しない側の表面Fのボルト孔9の周囲にのみ、塗装14が剥離された粗面13を形成すればボルト17、ナット18、及び座金16の共回りと共に緩みを防止することができる。また、座金16を使用しない場合においてもボルト17、及びナット18の共回りと共に緩みを防止することができるのは勿論である。   As shown in FIG. 6, for example, when fixing the plate-like member 8 c to the member X having a predetermined thickness and having the screw hole 19, the surface F on the side not in contact with the member X If the rough surface 13 from which the coating 14 is peeled is formed only around the bolt hole 9, loosening can be prevented together with the rotation of the bolt 17, the nut 18, and the washer 16. Of course, even when the washer 16 is not used, loosening can be prevented together with the rotation of the bolt 17 and the nut 18.

そして、これらの部材8は、例えば金属から形成され、戸建住宅に使用される制震装置、耐震装置、免震装置、柱、基礎、床、屋根等の施工の際に使用される部材を始め、その他の家具や工作機械等に使用される部材であり、その形状も板状、角柱状を始め円筒状等であってもよく、特に限定されるものではない。また、塗装方法も電着塗装に限定されるものではなく、さらに、塗装14の代わりに部材8の表面が研磨され、または、メッキ等が施されていてもよい。   And these members 8 are formed from metal, for example, and are members used in the construction of seismic control devices, seismic devices, seismic isolation devices, pillars, foundations, floors, roofs, etc. used in detached houses. First, it is a member used for other furniture, machine tools, etc., and the shape thereof may be a plate shape, a prismatic shape, a cylindrical shape, etc., and is not particularly limited. Further, the coating method is not limited to electrodeposition coating, and the surface of the member 8 may be polished or plated or the like instead of the coating 14.

以上のようにして、切削工具1で部材8に形成されたボルト孔9の周囲の表面Fを荒らし、該部材8に施された塗装14を剥離し摩擦抵抗の大きい粗面13を形成することで、座金16を使用する場合には、座金16と部材8との間、そして、座金16を使用しない場合には、ボルト頭17aと部材8との間、及びナット18と部材8との間の摩擦力を向上させ、ボルト17をナット18に螺合する際に、ボルト17、ナット18、及び座金16の共回りと共に緩みを防止できるのである。   As described above, the surface F around the bolt hole 9 formed in the member 8 with the cutting tool 1 is roughened, and the coating 14 applied to the member 8 is peeled to form the rough surface 13 having a high frictional resistance. When the washer 16 is used, between the washer 16 and the member 8, and when the washer 16 is not used, between the bolt head 17a and the member 8 and between the nut 18 and the member 8. Thus, when the bolt 17 is screwed into the nut 18, loosening can be prevented together with the rotation of the bolt 17, nut 18, and washer 16.

本発明に係る切削工具1は、ボルト孔9の周囲を荒らすことによる塗装14の剥離だけでなく、削り部7の目の大きさを変えることにより、ボルト孔9の周囲のバフ研磨等にも利用可能である。   The cutting tool 1 according to the present invention not only peels off the coating 14 by roughening the periphery of the bolt hole 9, but also changes the size of the eyes of the shaving portion 7 so as to buff around the bolt hole 9 and the like. Is available.
