Claims (3)
- 液圧媒体で付勢される液圧ピストンにより、ボルトに張力を付与してボルトの締付け力を増大させるようにした、いわゆる、液圧式ボルト締付け装置であって、前記液圧ピストンが、液圧ピストンに付勢された力を被締付けボルトの端部に中間要素を介して伝達し、前記液圧ピストンおよび中間要素がケースで取り囲まれている液圧式締付け装置において、
前記締付け力を伝達する中間要素(14)が、その第1端部(18)で液圧ピストン(13)にねじ込まれ、第2端部(19)でボルト(11)にねじ込まれ、ケース(15)に、中間要素(14)の第1端部(18)に隣接して狭隘部(21)が、中間要素(14)の第2端部(19)に隣接して中間要素(14)の凹所(23)に係合する保持ピン(22)が、各々付設され、さらに、前記ケース(15)が、液圧ピストン(13)と中間要素(14)とを取り囲むケース部分(16)と蓋(17)とを有し、該蓋(17)が、前記保持ピン(22)とは異なる保持ピン(24)を介してケース部分(16)に固定されたことを特徴とする液圧式ボルト締付け装置。
- 締付け力を伝達する中間要素(14)が、前記液圧ピストンによって張力が付与された際に伸張するナットとして形成されたことを特徴とする請求項1記載の液圧式ボルト締付け装置。
- ケース(15)とボルト(11)で締め付けるべき部品(12)との間に、ボルト(11)にねじ込まれたナット(16)を包囲する加圧部材(25)が配置されたことを特徴とする請求項1又は2記載の締付け装置。
