ROTATING CLAMP FOR WORKPIECES WITH FIXING AND DAMPING DEVICE

摘要

The swivelling fixture, attached to a revolving table of a working machine consists of a swivelling plate (8) equipped with a lower and an upper pin (6, 7), which are arranged in arms of a base console (1). With the lower pin (6) a strengthening plate (9) is connected and this strengthening plate (9) is equipped with a conical hollow space (10), by which it is strengthened in a cone (11) formed in a body (12) of a lower bearing. The cone (11) concurrently forms a body of a main strengthening cylinder (13), whose piston (14) is axially anchored in the lower pin (6). The upper pin (7) is mounted in a flexible housing (17), pressed into a body (18) of an upper bearing, in which there is a radially arranged strengthening cylinder (18). The absorber assembly consists of a linear hydraulic motor (22) composed of a cylinder (25) and a piston rod (23), while the absorption is secured by absorbing contacts (30)<IMAGE>
