Title:
STEADY REST FOR SUPPORTING A CYLINDRICAL WORKPIECE
Document Type and Number:
WIPO Patent Application WO/2013/045416
Kind Code:
A3
Abstract:
The invention relates to a steady rest (16) having a supporting body (17), in which a supporting groove (10) extends in an extension direction (Y). A cylindrical workpiece (18) can be supported in the supporting groove (10). The steady rest (16) has a plurality of adjusting spindles (20a, 20b, 20c, 20d) for orienting and positioning the supporting groove (10). Preferably, at most two linear adjusting spindles (20a, 20b) and at least one pivoting adjusting spindle (20c, 20d) are provided. Each adjusting spindle (20a, 20b, 20c, 20d) serves for the relative adjustment of two adjusting parts (E) in an appropriate adjusting direction (X, Z, U1, U2). The adjusting direction (X, Z, U1, U2) of one adjusting spindle (20a, 20b, 20c, 20d) differs from the adjusting directions of the other adjusting spindles in each case. In order to prevent accidental adjustment of an adjusting spindle (20a, 20b, 20c, 20d), each adjusting spindle (20a, 20b, 20c, 20d) is assigned in each case a clamping means (30a, 30b, 30c, 30d). Each clamping means can produce a clamping force between the two adjusting parts (E) of an adjusting spindle (20a, 20b, 20c, 20d), wherein the clamping force is oriented transversely and preferably at right angles to the adjusting direction (X, Y, U1, U2) of the adjusting spindle (20a, 20b, 20c, 20d) in question.
