ROTATION DRUM ALIGNMENT ASCERTAINING DEVICE

摘要

In order to ascertain the placement of a rotation drum relative to the shaft axis of a spindle assembly, an alignment ascertaining device according to the present invention comprises a body portion made mountable on a mounting surface formed horizontally on the spindle assembly, the body portion having a guide face in the direction at right angles to the mounting surface; a linear guide portion mounted in an upward and down ward direction on a guide face; a slider mounted via a rolling member to the linear guide portion, the slider made movable in a direction in which the linear guide portion is installed; an arm member whose proximal end portion is attached to the slider and whose distal end portion extends toward the rotation drum; and a dial gauge mounted on the distal end portion of the arm member.
