  • Publication number: 20230055529
    Abstract: The present invention discloses a double-swing angle spindle head, in which an A-axis swing shaft is connected to the spindle head through the flange on the end face to realize the swing of the A-axis, and a crank connecting rod mechanism composed of a first rotating shaft, a second rotating shaft, a B-axis rotating shaft and a swing connecting rod realizes the swing of the B-axis under the push-pull action of the B-axis mechanism. Under the action of the linear push-pull mechanism, the linear axis feed movement between a ram and a saddle is realized. Thus, the freedom of movement range of the spindle head is improved, the rigidity, torque and precision of the spindle head are enhanced, and the volume and weight of the spindle head equipment are reduced.

  • Publication number: 20230055452
    Abstract: 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.

  • Publication number: 20230035467
    Abstract: The present invention provides a linkage swing head structure, including: a base, a drive mechanism and a spindle. The drive mechanism includes: a power mechanism, a connecting rod mechanism and a lead screw. An end of the spindle is fixed with a cutter, and the spindle is fixed on an end of the connecting rod mechanism. An end of the connecting rod mechanism fixed with the spindle is sleeved on a support bearing, the connecting rod mechanism can rotate around the support bearing, the support bearing is fixed on the base, and the other end of the connecting rod mechanism is movably connected to the lead screw. An output end of the power mechanism is connected to an end of the lead screw. The connecting rod mechanism adjusts the rotation angle of the spindle by sliding on the lead screw. The drive mechanism of the present invention is far away from the spindle, and the interference range thereof to the spindle is small.

  • Publication number: 20230032696
    Abstract: 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.
