摘要： A workpiece exchange device, including: a workpiece spindle; and a workpiece library, wherein: the workpiece spindle is arranged on a pallet, the pallet is arranged on a slide table, the pallet can move along a Z axis of a machine tool, and the slide table can move along an X axis of the machine tool; and the workpiece library is used to store workpieces, and the workpiece spindle can move along the X-axis and Z-axis of the machine tool and grab a workpiece. The present invention also discloses a method for exchanging workpieces. Through the coordinated movement of the slide table and the pallet, the workpiece spindle can take out a workpiece to be machined from the workpiece library or return a machined workpiece into the workpiece library. The present invention uses a machine tool coordinate system to grab the workpiece with high precision and high speed, and does not need to add an auxiliary mechanism, and has the advantages of simple structure, high stability and good reliability.

摘要： The present invention provides a blisk machining center, including: A-axis rotary assembly, B-axis rotary assembly and C-axis rotary assembly, wherein the A-axis rotary assembly drives the blisk to rotate, the B-axis rotary assembly drives an attachment head to rotate, and the attachment head drives a tool to machine the blisk, and the C-axis rotary assembly drives the A-axis rotary assembly to rotate, wherein the intersection of the rotation axis of the B-axis rotary assembly and the rotation axis of the C-axis rotary assembly is the center of the machining area of the blisk, and the tip point of the tool is on the rotation axis of the B-axis rotary assembly. In the present invention, the machining area is near the rotation center of the C-axis turntable, which ensures that the speed and acceleration of the movement of each physical axis are kept within a lower range than those of general machine tools when the machine tool is performing the machining of the 5-axis rotary tool center point.

摘要： The present invention discloses a five-axis vertical machining system with automatic loading and unloading, including a feeding mechanism, a loading mechanism, and a numerical control machine tool. The feeding mechanism is arranged in front of a ram assembly, and the feeding mechanism drives a raw material to move along an X axis and/or a Y axis of the numerical control machine tool; the loading mechanism is fixed on the ram assembly; and the loading mechanism moves along a Z axis of the numerical control machine tool to drive the raw material onto a cradle assembly of the numerical control machine tool. The present invention realizes an automatic loading and unloading function by setting a feeding mechanism capable of automatic feeding and a loading mechanism with automatic loading to cooperate with each other, thereby improving the working efficiency and saving manpower.
