Background
Conventionally, in order to perform automatic machining of a shaft, one robot is generally provided between two machining devices (e.g., a lathe and a drill) to perform mechanical conveyance of a workpiece. And after the current processing equipment finishes processing, the workpiece is carried to another processing equipment by the mechanical arm for processing.

For example, the machining time of the previous machining device is shorter than that of the subsequent machining device, and after the previous machining device finishes machining, the subsequent machining device does not finish machining, and at this time, the manipulator can only wait for the subsequent machining device to finish machining and then can carry the workpiece on the previous machining device to the subsequent machining device, so that machining interruption is generated, and the machining efficiency is influenced by the interruption.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a multi-process combined machining automatic production line which comprises a mechanical arm, a core-moving type double-spindle numerical control lathe and a multi-spindle combined machining numerical control machine tool, wherein the mechanical arm is used for carrying a shaft to be machined; the core-moving type double-spindle numerical control lathe is arranged in front of a manipulator by taking the manipulator as a center, and a multi-spindle combined machining numerical control machine tool is respectively arranged on the left side and the right side of the manipulator.
The utility model can realize continuous processing, reduce the interruption time and improve the processing efficiency.
