Title:
LINEAR DRIVE MECHANISM AND SHAPE MEASURING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/150681
Kind Code:
A1
Abstract:
Provided are: a linear drive mechanism in which a reduction in the measuring accuracy of a detector can be prevented; and a shape measuring machine provided with the linear drive mechanism. This liner drive mechanism is configured so that a contact or non-contact detector having sensitivity in a first axial direction is moved relative to a workpiece in a second axial direction perpendicular to the first axial direction. The liner drive mechanism is provided with: a drive shaft which extends in the second axial direction; a mover which is supported by the drive shaft without contact and which moves along the drive shaft together with the detector or the workpiece; a guide which is provided at a position offset relative to the drive shaft in a third axial direction perpendicular to both the first axial direction and the second axial direction, and which is parallel to the drive shaft; and a resistance force generation section which is provided on either the mover or the guide, is in contact with the other of the mover and the guide, and generates resistance force acting against the movement of the mover.
