ABSTRACT:
Pressing device for the relative axial displacement of two mutually coaxial parts that can only be displaced towards one another by using a high pressing power, for example collet chucks or clamping sleeves, into corresponding holes in tool or collet chuck holders. The device has a housing (7) consisting of two at least partially separable shells, which can be placed coaxially around the parts to be pressed. In the closed state, the housing has coaxial annular contacting edges (19, 20) for engaging with one of the parts to be pressed. In the inner chamber (21) of the housing there is an axially displaceable pressing plate (22) with an annular contacting edge (23) for engaging with the second part to be pressed. The press plate is displaced by a number of pressure cylinders (13, 14) arranged in a ring at equal angular distances between the housing and the press plate.
