The utility model adopts the technical proposal that:
an electric push rod capable of self-checking displacement comprises a push rod frame, wherein a cover plate is arranged at the upper opening of the push rod frame, a gearbox and a bearing are respectively arranged on two sides of the push rod frame, a sliding rail is arranged at the bottom in the push rod frame, a U-shaped frame is arranged on the power output end face of the gearbox, an encoder is arranged on the other end face of the U-shaped frame, a stepping motor is arranged on the power input end face of the gearbox, a transmission shaft is arranged in the gearbox, one end of the transmission shaft is arranged in the bearing, the other end of the transmission shaft; the sliding rail is provided with a sliding block, a front limit and a rear limit, and the sliding block is provided with a rack.
Further, a bolt is arranged on the transmission gear and is connected with the transmission shaft and the transmission gear.
Further, a coupler is arranged between the transmission shaft and the encoder shaft.
Furthermore, one end of the rack is provided with a mounting hole.
The utility model has the advantages that:
the utility model discloses use step motor, the gearbox is power, make the rack make linear motion to the object that acts on through drive gear, meanwhile, link because of encoder axle and transmission shaft, so the rotational speed signal of telecommunication of encoder output is unanimous with drive gear's rotational speed, through mathematical computation, computer control system just can know the displacement situation of being acted on the object at every moment, thereby realize electric putter displacement, the effect of self-checking integration, for the accurate control in automation and intelligent field, a new route is provided.
