Through cutting mill steady rest

摘要

An apparatus and method for a through cutting machining steady rest comprising a base plate fixed to a vertical support plate where an adjustable workpiece cradle may be adjusted to support a desired workpiece to be machined. A pair of opposing articulating side arms pivotally mounted upon the vertical plate wherein articulation of a fastening means will clampingly engage the side arms upon the desired workpiece. The side arms are engaged at points leaving a gap between the side arms for machining of the workpiece between the side arms. Rollers are implemented upon the ends of the side arms and along the came of the workpiece cradle to allow for a fixed axial hold of the workpiece while allowing the workpiece to be rotated around its longitudinal axis for further machining without the need of unclamping and repositioning the workpiece on the steady rest.

主权项

1. A workpiece steady rest apparatus comprising:
a) a baseplate; b) a vertical support plate having a curved workpiece support surface; c) a cradle having an upper surface corresponding to said curved workpiece support surface, said cradle adjustably attached to said vertical support plate whereby said cradle may be adjustably positioned with respect to said base plate; d) anchor support surfaces mounted to said vertical support plate; e) a pair of opposing side arms each having a pivot end and a workpiece engaging end, said pivot end of each said side arm pivotally attached to said vertical support plate, said side arms being articulable as desired to adjustably engage a workpiece between said opposing side arm; f) a workpiece support roller attached to said workpiece engaging end of said each side arm and a plurality of work piece support rollers attached to said cradle to extend above said upper surface of said cradle for grippingly engaging said workpiece; and g) a clamp whereby said rollers of side arms may be fixed to create clamping force upon said workpiece.
