发明名称 CLAMPING BUSHING AND CLAMPING DEVICE
摘要 The invention relates to a clamping bushing (21) for clamping in a bore (3) of a component (2), in particular of a workpiece to be clamped, wherein the clamping bushing (21) is radially contracted in a relaxed state such that the clamping bushing (21) can be inserted into the bore (3) and pulled out of the bore (3), whereas the clamping bushing (21) is radially expanded in a stressed state such that the lateral surface of the clamping bushing (21) forms a mechanical connection to the inner wall of the bore (3). According to the invention, the mechanical connection between the lateral surface of the clamping bushing (21) and the inner wall of the bore (3) is positive-locking and consists of a threaded connection. The invention further relates to a corresponding clamping device (1). An essential feature of the invention is also the possibility of being able to exchange the clamping bolt (tension anchor) by means of a bayonet coupling without having to open hydraulic lines and without removing the clamping element from the device.
