Abstract
A ball screw capable of sensing a push force in real time is formed of a screw rod, a screw nut mounted to the screw rod, a plurality of balls mounted between the screw rod and the screw nut, and a force sensor having a first fixture portion and a second fixture portion. The first and second fixture portions are fixed to a working bench and the screw nut, respectively, for making the force sensor sense how much the push force is while the screw nut drives the working bench to move. In this way, monitoring the voltage value outputted from the force sensor can monitor the push force in real time while the ball is working.
