Zusammenfassung:	The invention relates to an integrated semi-closed ball screw with a spline. The integrated semi-closed ball screw comprises a cylindrical shell; the driving assembly is arranged in the cylindrical shell; the ball nut is arranged on the cylindrical shell and is in threaded connection with the driving assembly; the ball spline groove is formed in one side of the cylindrical shell; the spline groove is formed in the ball nut and matched in the ball spline groove, a plurality of balls are arranged in the spline groove, and the balls can reduce friction force between the spline groove and the ball spline groove; reciprocating motion of the ball screw can be achieved only through one motor, the motor is installed on the right side of the ball screw to drive the ball screw to rotate forwards and backwards, and the ball nut can reciprocate on the ball screw; a cylindrical shell is installed on the outer side of the ball screw, a ball spline groove is formed in the cylindrical shell, a spline groove is formed in the
