Abstract
The invention relates to a screw rod stretching device. The screw rod stretching device comprises a framework structure, an upper workbench arranged on the framework structure, and a lower fixing piece. A motor stretching end is arranged at the left end of the framework structure, and the motor stretching end comprises two motor bases which are symmetrically arranged up and down. A servo motor is arranged in each motor base, and the two motor bases are connected through a first connecting piece. The first connecting piece is connected with a coupling, and the other end of the coupling is connected with a second connecting piece. The second connecting piece is connected with a screw rod. A bearing pedestal end is arranged at the right end of the framework structure, a third connecting piece is arranged at the bearing pedestal end, and the third connecting piece is connected with the screw rod. Lock nuts are arranged at the left end and the right end of the third connecting piece respectively. According to the screw rod stretching device, the screw rod is stretched by the servo motors, and the stretching length of the screw rod can be accurately controlled through the motors.
