Abstract
A measurable guide actuator is used to integrate a driving mechanism, a guide mechanism, and a position measuring member so as to form an integral simplifying construction, thereby facilitating the usage and thereby reducing consumption of material. The measurable guide actuator of the present invention uses a U-shaped guide track to function as the guide mechanism. The driving mechanism uses a screw or a belt. The position measuring member includes a ruler body mounted in the guide mechanism, and a reading head sealed in the sliding table to slide therewith so that the position measuring member can be used to measure the displacement position values.
Claims6
A measurable guide actuator comprising:
- a guide mechanism (1), a sliding table (4), a driving mechanism, and a position measuring member, wherein,
- said guide mechanism (1) is elongated with a substantially U-shaped cross-section, said U-shaped guide mechanism (1) has two sides each having an inner wall each defining an elongated first groove (11);
- said sliding table (4) is slidably mounted between said inner walls of said two sides of said U-shaped guide mechanism (1), and has two sides each defining a second groove (41) mating with said elongated first groove (11) of said U-shaped guide mechanism (1), a plurality of balls (32) inserted between said elongated first groove (11) of said U-shaped guide mechanism (1) and said second groove (41) of said sliding table (4), said sliding table (4) having a front end and a rear end each provided with an end cap (3) for allowing circulating rolling of said balls (32) so that said sliding table (4) can move along said elongated first groove (11) of said U-shaped guide mechanism (1);
- said driving mechanism provides a power for movement of said sliding table (4);
- and
- said position measuring member has a ruler body mounted on an inner side of said U-shaped guide mechanism (1) such that said position measuring member has a function of detecting a position of said sliding table (4).
