20120255407 | Steady rest - A steady rest for centering a rotationally symmetrical workpiece in a space comprises: two housing halves arranged at a distance from one another and connected together, a plate-shaped middle piece arranged between the two housing halves, the middle piece mounted in the housing halves by means of an actuator piston so it can be moved in an axial movement direction to the workpiece, two linear guide grooves disposed in both opposite end faces of the middle piece, with the linear guide grooves running in a cross-shaped arrangement and at an angle to the movement direction of the middle piece, two outer steady rest arms, each of which has its free ends mounted in each of the linear guide grooves of the middle piece in a movable arrangement, and a middle steady rest arm attached to the middle piece between the outer steady rest arms. | 10-11-2012 |
20120260779 | Steady rest - A steady rest for centering a rotationally symmetrical workpiece in a space, the rest comprising two housing halves arranged at a distance from one another and connected together, a plate-shaped middle piece disposed between the two housing halves, the middle piece being mounted in the housing halves by means of an actuator piston which can be moved in an axial direction to the workpiece, two linear guide grooves disposed in both opposite large-surface end faces of the middle piece, with the guide grooves running in a cross-shaped arrangement and at an angle to a movement direction of the middle piece, two outer steady rest arms, each mounted in one of the linear guide grooves of the middle piece in a movable arrangement, and a middle steady rest arm attached to the middle piece between the outer steady rest arms. | 10-18-2012 |
20130014620 | ELECTRIC-DRIVE STEADY RESTAANM HANGLEITER; EugenAACI HermaringenAACO DEAAGP HANGLEITER; Eugen Hermaringen DEAANM Schenk; PeterAACI NiederstotzingerAACO DEAAGP Schenk; Peter Niederstotzinger DE - A steady rest has a body juxtposable with a workpiece rotatable about a workpiece axis. Two arm elements are pivoted on the body and carry outer rollers radially engageable with the workpiece. A center element shiftable on the body in a straight line generally radially of the axis carries a center roller engageable radially with the workpiece. The rollers are angularly spaced about the workpiece. An electric actuator mounted on the body is connected by a transmission to the elements for displacing the respective roller radially relative to the workpiece. | 01-17-2013 |
20150020656 | AUTO-CENTERING APPARATUS OF A STEADY REST - An auto-centering apparatus of a steady rest has: a base part; a main support part installed on the top of the base part, and a loading unit installed on the top of the main support part; at least one side support part installed on the top of the base part and located at least one side of the main support part, and a loading unit installed on the top of the side support part; a lift-up module installed in the base part and coupled to the main support part; and a connecting unit installed between the main support part and the side support part. | 01-22-2015 |
