[0030] A hydraulic rod 8 is fixedly connected to the middle of the bottom of the moving block 7, and the telescopic end of the hydraulic rod 8 penetrates through the middle of the moving block 7. The bottom of the hydraulic rod 8 is fixedly connected to a driving block 9, and the top telescopic end of the hydraulic rod 8 is fixedly connected to a rotating seat 10.

[0031] Four symmetrically distributed positioning rods are fixedly connected to the bottom of the rotating seat 10, and all four positioning rods are slidably connected to the inside of the moving block 7. Two symmetrically distributed support columns 11 are fixedly connected to the top of the rotating seat 10, and a cam motor 12 is fixedly connected between the two support columns 11.

[0032] Two groups of sliding holes 13 and two threaded holes 14 are provided inside the driving block 9, and the two groups of sliding holes 13 and the two threaded holes 14 are vertically distributed inside the driving block 9 respectively, and each group of sliding holes 13 is located above the threaded hole 14.

[0033] Four guide rods 15 are fixedly connected to the bottom of the support frame 1, and the four guide rods 15 are distributed on the side of the bottom of the support frame 1, and every two symmetrically distributed guide rods 15 are set as a group.

[0034] The outside of the guide rod 15 is slidably connected with a mounting block 16, and two symmetrically distributed moving rods 17 are fixedly connected between the two mounting blocks 16. The two groups of moving rods 17 are vertically distributed at the bottom of the support column 11, and the two groups of moving rods 17 do not interfere with each other, and the moving rod 17 is slidably connected to the inside of the sliding hole 13.

[0035] A lead screw 18 is rotatably connected between the two mounting blocks 16, and one end of the lead screw 18 is rotatably connected with a connecting slider 19, and the connecting slider 19 is rotatably connected to the side of the support frame 1 through a slide rail.

[0036] Embodiment Two:

[0037] On the basis of Embodiment One, its specific working principle is as follows:

[0038] When the support slider 5 slides on the top of the guide rail 4, at this time the two support sliders 5 will drive the support rod 6 between the two support sliders 5 to move along with it, so that the moving block 7 moves along with the support rod 6, making the rotating seat 10, the support column 11 and the cam motor 12 on the top of the moving block 7 move. The lateral movement of the support slider 5 and the longitudinal movement of the moving block 7 on the top of the support rod 6 form a dual-axis slide table structure, enabling the cam connected to the output end of the cam motor 12 to move arbitrarily within the top plane of the support frame 1, improving the flexibility of the cam on the top of the support frame 1;

[0039] The lead screw 18 is driven by a motor to rotate between the two mounting blocks 16, so that the lead screw 18 rotates inside the threaded hole 14. Since the two lead screws 18 are perpendicular to each other and the two threaded holes 14 inside the driving block 9 are also symmetrically distributed, when the lead screw 18 rotates inside the threaded hole 14, it can drive the driving block 9 to rotate the moving rod 17 between the mounting blocks 16. Since the two groups of moving rods 17 are perpendicular to each other, the lead screw 18 can drive the driving block 9 to move arbitrarily within the bottom plane of the support frame 1. Since the top of the driving block 9 is connected to the moving block 7 through the hydraulic rod 8, the movement of the driving block 9 drives the moving block 7 to move on the top of the support frame 1;

[0040] When the moving rod 17 moves, the moving rod 17 slides on the outside of the guide rod 15 of the two mounting blocks 16 at its two ends, and the lead screw 18 will also drive the connecting slider 19 to slide on the outside of the slide rails on both sides of the support frame 1, so that the motor on the outside of the connecting slider 19 moves along with the mounting block 16;

[0041] When the telescopic end of the hydraulic rod 8 works, the hydraulic rod 8 will drive the rotating seat 10 to move vertically away from or close to the moving block 7. During the movement of the rotating seat 10, the four positioning rods at the bottom of the rotating seat 10 all slide inside the moving block 7, so that the rotating seat 10 remains stable during the vertical movement. The moving block 7 moves along the X and Y axes on the top of the support frame 1. At the same time, the hydraulic rod 8 drives the rotating seat 10 to move on the Z axis, and the angle of the support column 11 and the cam motor 12 is adjusted by the rotation of the rotating seat 10 itself. At the same time, the cam motor 12 can rotate between the two support columns 11, so that the cam motor 12 can be independently adjusted in five directions, greatly improving the flexibility of the adjustment of the cam motor 12.
