Abstract

A triaxial motion device includes first, second and third bases, first and second power sources, and a workpiece positioning member. The first power source is disposed on the first base and has a first driving shaft. The second base is connected with the first driving shaft through a cannular rotary shaft in a way that the second base is rotatable about a first axis. The second power source is disposed on the first base and has a second driving shaft penetrating through the cannular rotary shaft. The third base is connected with the second driving shaft in a way that the third base is rotatable about a second axis perpendicular to the first axis. The workpiece positioning member is disposed on the third base and rotatable about a third axis perpendicular to the second axis. Therefore, the triaxial motion device has small volume and performs highly precise motion.

Dependent claims

A triaxial motion device comprising:

a first base;
a first power source disposed on the first base and having a first driving shaft;
a cannular rotary shaft connected with the first driving shaft of the first power source in a way that the cannular rotary shaft is capable of being driven by the first driving shaft to rotate synchronously with the first driving shaft;
a second base connected with the cannular rotary shaft in a way that the second base is capable of being driven by the cannular rotary shaft to rotate relative to the first base about a first axis;
a second power source disposed on the first base and having a second driving shaft rotatably penetrating through the cannular rotary shaft;
a third base connected with the second driving shaft of the second power source in a way that the third base is capable of being driven by the second driving shaft of the second power source to rotate relative to the second base about a second axis perpendicular to the first axis;
and
a rotary unit disposed on the third base and having a workpiece positioning member rotatable relative to the third base about a third axis perpendicular to the second axis.
