[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Lathes are the most important type of metal cutting machine tools. In general machine manufacturing factories, lathes are the most numerous and are also called machine tools. Drills, reamers, dies and knurling tools can also be used on lathes for corresponding processing. The function of a lathe is to cut rotating surfaces of various sizes and shapes, as well as spiral surfaces.

[0003] The existing technology requires processing a gear shaft product with a square structure at both ends. The existing technology has low processing efficiency using a milling machine. A new process is developed to first use a milling machine to process one end, and then use a lathe to turn the other end into a square. However, the squares at both ends need to be identical and symmetrical, and there should be no tilt during installation. Therefore, the existing lathe cannot guarantee the installation accuracy.

[0004] Therefore, it is necessary to design an efficient square positioning gear shaft processing machine to solve the above problems. Utility Model Content

[0008] Preferably, the adjustment assembly includes a bottom fixing plate arranged on the CNC lathe, a transverse module arranged on the bottom fixing plate, a longitudinal module driven by the transverse module, and a tool mounting seat driven by the longitudinal module.

[0009] Preferably, the tool assembly comprises a tool servo motor installed on the adjustment assembly and a tool mounting frame driven by the tool servo motor; the tool mounting frame is circular and has a plurality of tool mounting slots formed thereon.
