Abstract
A measuring device, includes a guiding rail, a sliding unit levitatedly slidably engaged with the guiding rail, and a measuring unit fixed to the sliding unit and comprising at least one dial gauge mounted thereto.
Claims14
An assembly comprising:
- a to-be-measured device comprising at least one of an adjustable threaded shaft and an adjustable slideway;
- two fiducial blocks set on the to-be-measured device;
- a guiding rail to be abutted against the fiducial blocks and mounted to the to-be-measured device to be substantially parallel with the at least one of an adjustable threaded shaft and an adjustable slideway;
- a sliding unit levitatedly slidably engaged with the guiding rail, and linearly slidable along a working face of the guiding rail;
- and
- a measuring unit fixed to the sliding unit and comprising at least one probe mounted thereto to measure the at least one of an adjustable threaded shaft and an adjustable slideway for detecting the parallelism between the at least one of an adjustable threaded shaft and an adjustable slideway and the guiding rail;
- wherein the fiducial blocks cooperatively form a fiducial line for the guiding rail to be arranged therealong.

An assembly comprising:
- a to-be-measured device comprising an adjustable elongate object;
- two fiducial blocks set on the to-be-measured device;
- a guiding rail to be abutted against the fiducial blocks and mounted to the to-be-measured device to be substantially parallel with the object, wherein the fiducial blocks cooperatively forms a fiducial line for the guiding rail to arrange therealong, and linearity of a working face of the guiding rail is limited to be within 0.003 mm;
- a sliding unit levitatedly slidably engaged with the guiding rail, and linearly slidable along the working face of the guiding rail;
- and
- a measuring unit fixed to the sliding unit and comprising at least one probe mounted thereto to measure the object for detecting the parallelism between the object and the working face of the guiding rail.
