To prevent metal waste from staying on the thread groove on the surface of the screw screw 41g, and affecting the transmission accuracy of the screw screw 41g to the ball slide 41b, the workpiece fixing and lifting structure formed by the workpiece positioning device 7 can make vertical The fixed cylindrical workpiece performs a stable upward or downward linear motion, so that the multi-position drilling structure formed by the multi-station drilling device 4 can perform continuous circular equidistant multi-position drilling operations on the cylindrical workpiece, thereby The processing efficiency of a specific cylindrical workpiece is greatly improved, because the present invention adopts the cylindrical workpiece clamping structure formed by the straight rail 72a, the translation push rod 72b, the clamping plate 72c, the horizontal slide rail 72d and the lifting push rod 72e, and controls the four axially symmetrically arranged clamps. The translation push rod 72b can make the two splints 72c merge or separate, so as to achieve the effect of vertically fixing the cylindrical workpiece. The workpiece stabilization structure formed by the sliding rod 74, the spring 75 and the pulley 76 is in contact with the two sides of the cylindrical workpiece through the two pulleys 76 arranged symmetrically in the axis, and the elastic force generated by the spring 75 is used to push the pulley 76 to be close to the cylindrical workpiece. The workpiece is reinforced vertically, and the vertical motion stability of the cylindrical workpiece can be effectively improved.
