Example Embodiment
[0006] Specific embodiment 1: The five-axis linkage parallel-series CNC machine tool in this embodiment adopts a vertical structure, which includes a frame 1, a motion platform 2, and connecting rods. There are four connecting rods, and one end of the four connecting rods is connected to the frame. 1 is connected, the other ends of the four connecting rods are all hinged to the motion platform 2; the motion platform 2 is arranged below the frame 1, and when working, the motion platform 2 is equipped with tools for processing; on the motion platform 2 There is also a mobile worktable 4 underneath, and the workpiece to be processed is fixed on the mobile worktable 4. The four connecting rods and the motion platform 2 are connected by ball hinges, which can realize the movement of the connecting rods relative to the motion platform in various directions, and the four spherical hinges are spaced 90 degrees apart on the plane of the motion platform 2 The symmetrical arrangement can kee...
Example Embodiment
[0008] Embodiment 2: The difference between this embodiment and the first embodiment is that a slideway 5 is fixed on the frame 1, one slideway 5 is provided, and two sliding blocks are provided on the slideway 5; Two of the connecting rods are fixed-length connecting rods, and the two fixed-length connecting rods are respectively connected to two sliding blocks through a rotating pair; the other two connecting rods of the four connecting rods are telescopic connecting rods. The rod and the frame 1 are connected by a Hooke hinge.
[0009] The overall structure of this embodiment is as follows figure 2 As shown in the figure, the coordinate system is established, the Y axis is along the direction of the slide 5, the X axis is in the plane formed by the slide 5 and the fixed rods 1-1, 1-2 of the frame 1, and the Z axis is vertically upward. The motion platform 2 is connected to the fixed rod 1 of the frame 1 and the frame 1 through two fixed-length connecting rods 3-1-1, 3-1-2 and ...
Example Embodiment
[0010] Specific embodiment three: this embodiment is different from specific embodiment one in that two cranks are installed on the frame 1, and the two cranks are respectively connected with the frame 1 through a rotating pair; two of the four connecting rods One connecting rod is a fixed-length connecting rod, and two fixed-length connecting rods are respectively connected with two cranks through a rotating pair; the other two connecting rods of the four connecting rods are telescopic connecting rods, and the two telescopic connecting rods are respectively connected to the frame 1 Connected by Hooke hinge.
[0011] The overall structure of this embodiment is as follows image 3 As shown in the figure, the coordinate system is established, the X axis is in the plane formed by the fixed rods 1-1, 1-2 of the frame 1, the Z axis is vertical upward, and the Y axis is with the fixed rods 1-1, 1 of the frame 1. -2 parallel, the motion platform 2 passes through "two fixed-length connecti...
