[0034] Workflow: Before use, connect the power supply. This device is equipped with an external controller, which is electrically connected to the first motor 14, infrared rangefinder 17, second motor 24, and electric telescopic rod 26. Manually operating the external controller can adjust the operating status of the first motor 14, infrared rangefinder 17, second motor 24, and electric telescopic rod 26. Different models of suction cup bodies 31 have different numbers of suction nozzles 32, and their shapes and sizes are also different. Therefore, the distance between the first locking groove 33 and the second locking groove 34 of different models of suction cup bodies 31 is different, and the spacing between the two first locking grooves 33 of different models of suction cup bodies 31 is also different. The spacing between the two second locking grooves 34 of different models of suction cup body 31 is also different. However, the spacing between the two first locking grooves 33 of each model of suction cup body 31 is equal to the spacing between the two second locking grooves 34. Furthermore, the spacing between the two second locking grooves 34 is marked on each model of suction cup body 31. All of the above are existing technologies. Before using this device, the first mounting base 11 and the second mounting base 21 are bolted to the base of the CNC milling machine. The first fixing plate 12 is fixed by the first mounting base 11, and the second fixing plate 22 is fixed by the second mounting base 21. When using this device, the operator first selects a specific model of suction cup body 31... Installation involves starting the first motor 14 and the second motor 24 via an external controller. The external controller ensures that the actions of the first motor 14 and the second motor 24 are completely synchronized. The first motor 14 drives the first adjusting shaft 13 to rotate, and the second motor 24 drives the second adjusting shaft 23 to rotate. The first adjusting shaft 13 adjusts the distance between the two first adjusting blocks 15, and the second adjusting shaft 23 adjusts the distance between the two second adjusting blocks 25. The infrared rangefinder 17 measures the distance between the two first locking blocks 16. The operator can set the distance between the two first locking blocks 16 using the external controller. The pre-adjustment is completed by making the distance between the two first locking blocks 16 equal to the distance between the two second locking slots 34 marked on the suction cup body 31. Then, the staff places the suction cup body 31 between the first locking block 16 and the second locking block 27, and moves the suction cup body 31 to the left so that the first locking block 16 is inserted into the first locking slot 33. Since the front and rear edges of the first locking slot 33 are both curved surfaces, the first locking block 16 can be inserted quickly and accurately. Then, the electric telescopic rod 26 is extended to the left by the external controller, so that the second locking block 27 is moved to the left and inserted into the second locking slot 34, thus fixing the suction cup body 31 stably.This device uses two adjustable first adjusting blocks 15 to move the first locking block 16 and the infrared rangefinder 17, and two adjustable second adjusting blocks 25 to move the electric telescopic rod 26 and the second locking block 27. The infrared rangefinder 17 measures the distance between the two first locking blocks 16, and the first locking blocks 16 position the suction cup body 31. The electric telescopic rod 26 moves the second locking block 27 left and right, and the second locking block 27 locks the suction cup body 31. This device allows for quick assembly and disassembly of different models of suction cup bodies 31. The suction cup body 31 remains stably fixed even after repeated assembly and disassembly, and the operation is simple, quick, time-saving, and labor-saving.
