TOOL COUPLING WITH A RADIALLY ELASTICALLY EXPANDABLE COUPLING SLEEVE AND A SHAFT WITH A CLAMPING BODY

摘要

The present invention is a device connected to two mechanical parts with respect to the shaft 12 protruding from the first mechanical part 10, which connects the annular surface 20 surrounding the shaft 12 at the base and also the shaft 12. A device having a coupling sleeve 16 protruding from a second instrument part 14 having a groove 18 for receiving a recess, the end face 22 being compressed against the annular face 20 during a fixed operation. Can be. In order to achieve a shaft 12 self-centered radius fixation in the sleeve 16, the shaft 12 has an axially open cavity 24 facing the front of the shaft and is also axially arranged in the cavity 24. 28. The fixed body 20 is loosely screwed with the outer screw 72 in the inner screw 70 of the hollow shaft and is blocked from rotating. The size of the cavity wall 38 is such that it can extend or resilient semicircularly below the screw franks 26 and 30 and the franks incline in the direction of the axial opening 32 and axially fix the fixture 28. When compressing, a compression force is applied to the inside of the fixed sleeve 16.
