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

摘要

device for assembling two parts of tools by means of a shaft (12) at the level of the first protruding portion (10), a ring (20) surrounding the base of the stem (12) and a connecting sleeve (16) projecting at the level of the second part (14).with a cavity (18) for receiving the stem (12) and an outer surface (22) which can be pressed against the surface of the ring (20) during application.in order to obtain an automatic centering clamp radially with the stem (12) to the inside of the connecting sleeve (16), as well as the application of planar surfaces, the shaft (12) includes a cavity (24) axially toward the open end located on the side of the rod, and a clamping element (28) movable axially within the cavity (24).the clamping element (20) is screwed with the game in a tapping rod (70) is drilled with a male thread (72), and is locked in rotation.the wall (38) of the cavity is dimensioned so as to be formed a bulge or an extension elastic in the axial radial clamping element clamp (28) on the sides of fillets (26, 30) and the diagonal can be clamped against the inner surface of the sleeve racco rdement (16).
