The turning system for processing shaft parts as claimed in claim 3, wherein a distance sensor is disposed on the sliding cylinder or the mounting frame for detecting the moving distance of the pushing plate, whether the shaft part is inserted into the chuck can be determined according to the moving distance of the pushing plate detected by the distance sensor, and when it is determined that the shaft part is inserted into the chuck, the clamping jaw cylinder of the first clamping arm is released and the telescopic cylinder is retracted; when judging during axle type part does not insert the chuck, the push cylinder withdrawal, the rotation axis is rotatory, makes the vertical setting up of first press from both sides the staff, opens clamping jaw cylinder, and axle type part can adjust its position in clamping jaw cylinder automatically at the action of gravity, and then clamping jaw cylinder presss from both sides tightly, and the rotation axis drives first press from both sides the staff rotation to make axle type part the axis with the axis collineation of chuck, push cylinder promotion rotation axis removes towards the chuck.
5. A turning system for machining shaft parts according to claim 1, characterized in that the lathe body is a common lathe or a numerically controlled machine tool.
