Claims (3)

  1. 주축은 주축 하우징 내에 회전가능하게 지지되고, 그의 앞끝에서 견인스터드가 갖추어진 공구 홀더와 함께 끼워지게 되도록 형성된 공구장착구멍에 수납되며, 인장막대의 앞끝에서 상기 견인스터드를 클램프하기 위한 콜렛이 갖추어진 공구클램핑 인장막대와 상기 인장막대를 축방향으로 이동시키기 위한 장치를 포함하고 있는, 공작기계의 주축구동용 장치에 있어서, 상기 인장막대로부터 상기 주축까지 토오크를 전달하기 위하여 상기 주축의 내부면과 상기 인장막대의 외주 사이로 개재된 장치로 구성되며, 상기 인장막대는 상기 주축의 구동원에 연결된 것을 특징으로하는 공작기계의 주축구동용 장치.
  2. 제1항에 있어서, 상기 토오크를 전달하기 위한 장치는 키이홈과 그 안에서 미끄럼 운동이 가능한 키이로 구성되며, 상기 키이 및 홈은 각각 상기 인장막대 및 주축에 대하여 제공된 것을 특징으로 하는 공작기계의 주축구동용 장치.
  3. 제1항에 있어서, 상기 인장막대를 축방향으로 이동시키기 위한 상기 장치는 유압실린더, 축방향으로 이동가능하게 되도록 상기 유압실린더내에 수용된 유압피스톤, 및 상기 인장막대를 둘러싸며 상기 주축의 뒤끝과 상기 유압 피스톤 사이로 개재된 공구를 클램핑 접시형 스프링들로, 구성되는 것을 특징으로 하는 공작기계의 주축구동용 장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
