It is composed of at least a pin 28 and a pair of tension springs 30 that pull the pair of holder pins 28 in a direction away from the force point P1.
図示の実施形態のホルダー支持部２６は、上端部に円弧状の切り欠き２６ａを有する矩形板から構成され、切り欠き２６ａにおいてホルダーを支持するようになっている。ホルダーピン２８は、ホルダー支持部２６の幅方向両端部から幅方向外側に突出している。図２に示すとおり、ホルダー支持部２６の幅方向両端部には円形凹所３２が形成されており、円形凹所３２はホルダーピン２８の下方に位置している。 The holder support portion 26 of the illustrated embodiment is composed of a rectangular plate having an arc-shaped notch 26a at the upper end portion, and the holder is supported by the notch 26a. The holder pins 28 project outward in the width direction from both ends in the width direction of the holder support portion 26. As shown in FIG. 2, circular recesses 32 are formed at both ends of the holder support portion 26 in the width direction, and the circular recesses 32 are located below the holder pin 28.
図１に示すとおり、ホルダー装着部６はアーム４の作用点Ｐ２に配設され、一対のホルダーピン２８はアーム４の一対の長穴１４に挿入されている。引っ張りバネ３０の上端部はアーム４のアームピン１６に固定され、引っ張りバネ３０の下端部はホルダーピン２８に固定されている。そして、引っ張りバネ３０においては、ホルダーピン２８を力点Ｐ１から離れる方向（上方）に引っ張っており、ホルダーピン２８を長穴１４の上端側に位置づけている。また、ホルダー装着部６の各円形凹所３２にはアーム４のボールプランジャ１８が嵌まり込んでおり、ホルダー装着部６はボールプランジャ１８によって解除自在に固定されている。 As shown in FIG. 1, the holder mounting portion 6 is arranged at the action point P2 of the arm 4, and the pair of holder pins 28 are inserted into the pair of elongated holes 14 of the arm 4. The upper end of the tension spring 30 is fixed to the arm pin 16 of the arm 4, and the lower end of the tension spring 30 is fixed to the holder pin 28. Then, in the tension spring 30, the holder pin 28 is pulled in the direction away from the force point P1 (upward), and the holder pin 28 is positioned on the upper end side of the elongated hole 14. Further, the ball plunger 18 of the arm 4 is fitted in each circular recess 32 of the holder mounting portion 6, and the holder mounting portion 6 is releasably fixed by the ball plunger 18.
図３には、上述したとおりのホルダー着脱工具２によって工作機械の主軸に着脱されるホルダー３４が示されている。ホルダー３４は、加工用の工具Ｔを保持する円柱状の保持部３６と、保持部３６の軸方向片側端部に接続され保持部３６よりも直径が大きい大径部３８と、大径部３８の軸方向片側端部から軸方向片側に向かって次第に直径が小さくなるテーパー部４０とを有する。大径部３８の軸方向中間部には環状溝４２が形成されている。 FIG. 3 shows a holder 34 that is attached to and detached from the spindle of the machine tool by the holder attachment / detachment tool 2 as described above. The holder 34 has a columnar holding portion 36 that holds the tool T for machining, a large diameter portion 38 that is connected to one end of the holding portion 36 in the axial direction and has a larger diameter than the holding portion 36, and a large diameter portion 38. It has a tapered portion 40 whose diameter gradually decreases from one end in the axial direction to one side in the axial direction. An annular groove 42 is formed in the axially intermediate portion of the large diameter portion 38.
図４には、ホルダー３４が着脱される工作機械４４が示されており、工作機械４４には円筒状の主軸４６が設けられている。図６を参照することによって理解されるとおり、主軸４６の内周面は、ホルダー３４のテーパー部４０に対応するテーパー状に形成されている。図示の実施形態の工作機械４４においては、図４に示すとおり、主軸４６の下方にマウンタ４８が固定され、マウンタ４８の幅方向両端部には幅方向外側に突出する一対の支持軸５０が装着されている。一対の支持軸５０は主軸４６に隣接し、一対の支持軸５０の軸方向と主軸４６の軸方向とが交差している。 FIG. 4 shows a machine tool 44 to which the holder 34 is attached / detached, and the machine tool 44 is provided with a cylindrical spindle 46. As understood by referring to FIG. 6, the inner peripheral surface of the main shaft 46 is formed in a tapered shape corresponding to the tapered portion 40 of the holder 34. In the machine tool 44 of the illustrated embodiment, as shown in FIG. 4, the mounter 48 is fixed below the spindle 46, and a pair of support shafts 50 projecting outward in the width direction are attached to both ends of the mounter 48 in the width direction. Has been done. The pair of support shafts 50 are adjacent to the main shaft 46, and the axial direction of the pair of support shafts 50 and the axial direction of the main shaft 46 intersect.
上述のホルダー着脱工具２を用いて工作機械４４の主軸４６にホルダー３４を装着する際は、まず、図５に示すとおり、ホルダー支持部２６の切り欠き２６ａにホルダー３４の環状溝４２を嵌めて、ホルダー支持部２６によってホルダー３４を支持する。次いで、図６（ａ）に示すとおり、ホルダー着脱工具２の係合部８を工作機械４４の支持軸５０に係合させる（掛ける）と共に、ホルダー３４のテーパー部４０を主軸４６に挿入する。なお、この時点では、テーパー部４０の外周面と主軸４６の内周面との間には間隙が存在し、ホルダー３４は主軸４６に装着されていない。次いで、アーム４の力点Ｐ１をなす最下段のスペーサ２２を把持して、係合部８を中心として図６の紙面上方から見て時計回りにアーム４を回転させる。 When mounting the holder 34 on the spindle 46 of the machine tool 44 using the holder attachment / detachment tool 2 described above, first, as shown in FIG. 5, the annular groove 42 of the holder 34 is fitted into the notch 26a of the holder support portion 26. , The holder 34 is supported by the holder support portion 26. Next, as shown in FIG. 6A, the engaging portion 8 of the holder attachment / detachment tool 2 is engaged (hanged) with the support shaft 50 of the machine tool 44, and the tapered portion 40 of the holder 34 is inserted into the spindle 46. At this point, there is a gap between the outer peripheral surface of the tapered portion 40 and the inner peripheral surface of the main shaft 46, and the holder 34 is not attached to the main shaft 46. Next, the lowermost spacer 22 forming the power point P1 of the arm 4 is gripped, and the arm 4 is rotated clockwise around the engaging portion 8 when viewed from above the paper surface of FIG.
そうすると、図６（ｂ）に示すとおり、ボールプランジャ１８によるホルダー装着部６の固定が解除され、ホルダー装着部６と共にホルダー３４が主軸４６の奥に向かって前進する。これによって、主軸４６にホルダー３４を装着させることができる。ホルダー着脱工具２においては、支点となる係合部８から作用点Ｐ２までの長さが、係合部８から力点Ｐ１までの長さよりも短いので、テコの原理により、工作機械４４の主軸４６にホルダー３４を容易に装着させることができる。すわなち、ホルダー着脱工具２の力点Ｐ１に加える力は、ホルダー着脱工具２を用いずにホルダー３４を主軸４６に装着させる場合にホルダー３４に加える力よりも小さい。 Then, as shown in FIG. 6B, the fixing of the holder mounting portion 6 by the ball plunger 18 is released, and the holder 34 advances toward the back of the main shaft 46 together with the holder mounting portion 6. As a result, the holder 34 can be mounted on the spindle 46. In the holder attachment / detachment tool 2, the length from the engaging portion 8 serving as the fulcrum to the working point P2 is shorter than the length from the engaging portion 8 to the force point P1. The holder 34 can be easily attached to the device. That is, the force applied to the force point P1 of the holder attachment / detachment tool 2 is smaller than the force applied to the holder 34 when the holder 34 is attached to the spindle 46 without using the holder attachment / detachment tool 2.
また、ホルダー着脱工具２を用いて、工作機械４４の主軸４６からホルダー３４を取り外す際は、まず、係合部８を支持軸５０に係合させると共に、ホルダー支持部２６をホルダー３４の環状溝４２に嵌めて、図６（ｂ）に示す状態にする。次いで、アーム４の力点Ｐ１をなす最下段のスペーサ２２を把持して、係合部８を中心として図６の紙面上方から見て反時計回りにアーム４を回転させる。そうすると、テコの原理により、工作機械４４の主軸４６からホルダー３４を容易に取り外すことができる。このように、図示の実施形態のホルダー着脱工具２を用いることにより、工作機械４４の主軸４６にホルダー３４を容易に着脱することが可能となる。 When removing the holder 34 from the spindle 46 of the machine tool 44 by using the holder attachment / detachment tool 2, first, the engaging portion 8 is engaged with the support shaft 50, and the holder support portion 26 is formed into the annular groove of the holder 34. It is fitted to 42 to bring it into the state shown in FIG. 6 (b). Next, the lowermost spacer 22 forming the force point P1 of the arm 4 is gripped, and the arm 4 is rotated counterclockwise when viewed from above the paper surface of FIG. 6 with the engaging portion 8 as the center. Then, according to the principle of leverage, the holder 34 can be easily removed from the spindle 46 of the machine tool 44. As described above, by using the holder attachment / detachment tool 2 of the illustrated embodiment, the holder 34 can be easily attached / detached to / from the spindle 46 of the machine tool 44.
