[0024] A support plate 211 is provided on one side of the movable plate 206 away from the second linear module 207, wherein a lifting cylinder 212 is arranged side by side on one side of the support plate 211; an "L"-shaped lifting seat 213 is fixedly connected to the top of the piston rod of the lifting cylinder 212, and the "L"-shaped lifting seat 213 can move up and down under the drive of the lifting cylinder 212, and the "L"-shaped lifting seat 213 is slidably connected with the support plate 211 to ensure its stable lifting; a double-axis cylinder 214 is also fixedly installed on one side of the "L"-shaped lifting seat 213, wherein the double-axis cylinder A third suction cup 5 is provided at the front end of the piston rod 214, wherein the third suction cup 5 is used to adsorb the workpiece 6 to be processed placed on the third linear module 216, and transfer it to the processing table 7 on the CNC machine tool body 1; when the workpiece 6 is processed, the workpiece 6 on the processing table 7 is transferred to the workpiece placement table 218 set on the third linear module 216 by the third suction cup 5, thereby realizing stable adsorption and efficient movement of the workpiece 6, thereby greatly simplifying the loading and unloading process and improving the automation degree and production efficiency of the machining center.

[0025] Please refer to Figure 2 , Figure 3 As an embodiment of the utility model, the double-headed cylinder 210 is fixedly connected to the support arm 209 through a cylinder mounting seat 215, wherein the top ends of the two piston rods of the double-headed cylinder 210 are respectively installed with a first suction cup 3 and a second suction cup 4 of the same structure.

[0026] In the above-mentioned scheme, the double-headed cylinder 210 is a special cylinder, which has two independent piston rods, each of which can perform independent reciprocating motion in the cylinder body, and the two piston rods can be controlled by two independent air sources or different control valves of the same air source respectively; the double-headed cylinder 210 is firmly fixedly connected to the support arm 209 through the cylinder mounting seat 215. This connection method ensures the stability and reliability of the double-headed cylinder 210 during operation, and also enables the double-headed cylinder 210 to be accurately adjusted in position as needed; when loading and unloading is required, the first suction cup 3 or the second suction cup 4 generates an adsorption force under the action of air pressure, thereby tightly adsorbing the workpiece 6, and this adsorption force is sufficient to ensure The workpiece 6 will not fall off or shake during the movement, ensuring the accuracy and safety of loading and unloading; once the workpiece 6 is successfully adsorbed, the double-headed cylinder 210 can drive the first suction cup 3 or the second suction cup 4 and the adsorbed workpiece 6 to move through the telescopic movement of its piston rod.
