[0036] like Figures 3 to 7As shown, the loading and positioning device 2 includes a lifting device 26, a loading conveyor line 21, a limit plate 28, a positioning base 27, a loading sensor 24, and a support base 25. The lifting device 26 is installed on the bottom base 11 and is symmetrically located on both sides of the lifting frame 12. The top of the lifting device 26 is connected to the loading conveyor line 21. The limit plates 28 are symmetrically installed on the top of the loading conveyor line 21. The positioning base 27 is movably arranged on the loading conveyor line 21 and is located between the conveying wheel 22 and the limit plate 28 of the loading conveyor line 21. The positioning base 27 is used to fix the porcelain sleeve 95; the loading sensor 24 is installed on the top of the loading conveyor line 21 and is used to position the positioning base 27 so that the porcelain sleeve 95 is coaxial with the lifting clamping device 3 and the rotating assembly device 4; the support base 25 is installed on the bottom base 11 and is located at the bottom of the loading conveyor line 21 and is used to support the positioning base 27.

At this time, the clamping rod 49 extends out of the outside of the compression sleeve 40, and then the electric 43 is assembled to drive the clamping rod 49 and the nut 91 to retract into the inside of the compression sleeve 40. The loading positioning device 2 enters the loading conveyor line 21 through the feeding conveyor line, and then the loading robot inserts the porcelain sleeve 95 onto the positioning column 272 through the loading claws. When the loading sensor 24 detects the positioning column 272, the loading conveyor line 21 stops, and then the lifting motor starts, and the lifting reducer 261 drives the turbine elevator 262 to drive the loading conveyor line 21 down. The positioning base 27 drops to the top of the support base 25 and presses onto the limit plate 28, so that the positioning base 27 is fixed, thereby realizing the porcelain. The sleeve 95 is positioned; then the lower drive motor is started, the clamping base 31 descends until the oil pillow 93 descends to the top of the porcelain sleeve 95, and then the lower clamping jaws 372 release the oil pillow 93, the oil pillow 93 enters the interior of the porcelain sleeve 95, and the clamping base 31 continues to descend until the flange 94 is inserted into the top of the porcelain sleeve 95, and then the middle clamping jaws 362 release the flange 94, the flange 94 is inserted into the interior of the porcelain sleeve 95 and is located above the oil pillow 93; the clamping base 31 continues to descend to the set position, and then the upper pressure cylinder 324 retracts, and the upper The clamping jaws 325 drive the base 92 to be pressed onto the top of the flange 94, and then the lifting motor 521 drives the lifting base plate 51 and the rotating base 41 to descend to the set position, and then the locking cylinder 542 inserts the locking rod 544 into the locking hole 547; the pressing electric cylinder 53 drives the rotating base 41 to descend, and the rotating base 41 drives the pressing sleeve 40 to press onto the base 92, and then the upper clamping jaws 325 release the flange 94, and the pressing electric cylinder 53 continues to press the base 92 into the interior of the porcelain sleeve 95 through the pressing sleeve 40.
