| description | To provide a tool holder capable of suppressing the transmission of heat or vibrations generated at machining to a main shaft of a machine tool.SOLUTION: A tool holder 100 is composed of a body portion 110, a cover 120, and a sleeve 130. In the sleeve 130, while being inserted in a cover inner space part 120a1, sleeve outer peripheral parts 132a and 132e are adhered to a cover inner peripheral part 121a. In the cover 120, while a projecting portion 120C is inserted in a body portion inner space part 110a1, cover outer peripheral parts 122b and 122c are adhered to a body portion tip end surface 110A and a body portion inner peripheral surface part 111a. When the pressure of a pressurized medium injected in a sealing space including body portion passages 115 and 118, cover passages 124 and 125, and pressurized spaces 136a and 136b, grip portions 134a and 134b are elastically deformed inward in a diametrical direction, and a shank portion of a tool 200 inserted in a sleeve inner space 130a is gripped.SELECTED DRAWING: Figure 1
【課題】加工時に発生する熱や振動が工作機械の主軸に伝達するのを抑制することができる工具ホルダを提供する。【解決手段】工具ホルダ１００は、本体部１１０、カバー１２０、スリーブ１３０により構成される。スリーブ１３０は、カバー内側空間部分１２０ａ１内に挿入された状態で、スリーブ外周面部分１３２ａおよび１３２ｅが、カバー内周面部分１２１ａに固着される。カバー１２０は、突部１２０Ｃが本体部内側空間部分１１０ａ１内に挿入された状態で、カバー外周面部分１２２ｂおよび１２２ｃが、本体部先端面１１０Ａおよび本体部内周面部分１１１ａに固着される。本体部通路１１５、１１８、カバー通路１２４、１２５、加圧空間１３６ａ、１３６ｂを含む密閉空間内に注入されている加圧媒体の圧力が上昇すると、把持部１３４ａ、１３４ｂが径方向内側に弾性変形し、スリーブ内側空間１３０ａ内に挿入されている、工具２００のシャンク部が把持される。【選択図】図１ |
