<p>#CMT# #/CMT# The support (1) has outer retaining elements (5, 7) e.g. angular levers, cooperating with a center piece (8) by inner ends (10). A drive unit (61) is driven by an electric motor (21) such that rotation movements of the electric motor are changed by the drive unit into two different axial feed speeds of the center piece by force amounts aligned on a workpiece (4). A positive effective coupling (62) is used for adjusting the feed speeds of the center piece between the center piece and the motor. The coupling is automatically switched into different switching positions by the drive unit. #CMT#USE : #/CMT# Self-centering stationary support for clamping and/or holding workpieces on a rotary machine. #CMT#ADVANTAGE : #/CMT# The positive effective coupling is used for adjusting the feed speeds of the center piece between the center piece and the motor and automatically switched into different switching positions by the drive unit, thus accurately measuring and controlling feed and clamping movements of the stationary support by positioning the electric motor, ensuring compact and smaller installation space of the support, and using the rotating movements of the electric motor for rapid feed and clamping movements of the support arm. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of a self-centering stationary support with retaining elements arranged in a common plane. 1 : Self-centering stationary support 4 : Workpiece 5, 7 : Outer retaining elements 8 : Center piece 10 : Inner ends 21 : Electric motor 61 : Drive unit 62 : Positive effective coupling.</p> |
