Zusammenfassung
(EN)

The invention relates to a chuck (2) for retaining fixing elements (1) that are provided with a respective radial contact surface and a follower profile (17) for a friction welded connection on a component and for transmitting the rotational and contact forces that act on a fixing element. An annular receiving element (9) is provided in the chuck (2) for transmitting the rotational force, said receiving element tightly surrounding the fixing element comprising an axial polygonal profile that has been introduced. The chuck comprises a retractable contact part (18, 27) in the annular receiving element (9), which is guided in said element and which can be retracted in said element to permit the entry of a fixing element through a lateral opening (12) in the receiving element, the part being retracted behind said opening. After the introduction of a fixing element, the contact part can be displaced into a holding position against the contact surface (19) of the fixing element, in such a way that the fixing element presses against the component in the friction welding position during its rotation. In the holding position, the fixing element that has been introduced into the annular receiving element is held axially by retractable stop parts (10, 11) that project radially inwards.

본 발명은 부재에 마찰 용접 연결을 하고 체결 요소에 작용하는 회전력과 접촉력(contact force)을 전달하기 위해서 팔로워 프로파일(follower profile)(17)과 각각의 방사상 접촉 표면을 구비한 체결 요소(1)를 지지하기 위한 척에 관한 것이다. 환상의 수용 요소(9)는 상기 회전력을 전달하기 위하여 척(2)에 구비되며, 상기 수용 요소는 삽입된 축방향 다각형 프로파일을 포함하는 체결 요소를 꼭 맞게 둘러싼다. 상기 척은 상기 환상의 수용 요소(9)에 후퇴 가능한 접촉 부분(18, 27)을 포함하며, 이것은 상기 요소에서 안내되며 상기 수용 요소에서 횡방향 개구부(12)를 통해서 체결 요소가 삽입될 수 있도록 하기 위하여 상기 요소 내에서 후퇴할 수 있으며, 상기 접촉 부분은 상기 개구부 뒤로 후퇴한다. 체결 요소의 삽입 후에, 상기 체결 요소가 회전 중에 마찰 용접 위치에서 상기 부재에 대해서 압착할 수 있도록 하는 방식으로 상기 접촉 부분은 상기 체결 요소의 접촉 표면(19)에 대향한 지지 위치로 이동될 수 있다.상기 지지 위치에서, 환상의 수용 요소로 삽입된 상기 체결 요소는 반경 방향으로 내측으로 돌출한 후퇴 가능한 정지 부분(10, 11)에 의해서 축방향으로 지지된다.
