[0036] During operation, the piston rod of the oil casing fixing cylinder 32 is in an extended state. First, the fixing base plate 18 is horizontally placed by rotating the cylinder 16, and then the oil casing 9 is placed on the fixing base plate 18, and the flange hole 95 of the oil casing 9 is inserted into the round head pin 21 and the diamond pin 22. Then, the oil casing fixing cylinder 32 is started, and the oil casing fixing plate 33 presses the flange 93 of the oil casing 9 onto the fixing base plate 18. The oil casing fixing cylinder 32 and the oil casing fixing plate 33 fix the oil casing 9 from both ends of the oil casing 9, so that the fixing of the oil casing 9 is reliable and stable. Then insert the oil drain port 91 into the oil port clamping rod 43, start the oil port rotating clamping cylinder 41, the oil port rotating clamping cylinder 41 drives the oil port clamping rod 43 to rotate and presses the oil drain port 91 onto the oil drain hole of the oil pan 9, insert one end of the oil receiving pipe 92 into the oil receiving hole 912, and insert the other end of the oil receiving pipe 92 into the lower fixed groove 531 of the pipe fixing seat 53, then start the pipe fixing rotating clamping cylinder 54, the pipe fixing rotating clamping cylinder 54 drives the pipe fixing seat 56 to rotate to the top of the pipe fixing seat 53, and presses the oil receiving pipe 92 into the lower fixed groove 531 through the upper fixed groove 561. Then welding is carried out, first welding the oil drain port 91, then starting the rotating cylinder 16 to make the oil receiving hole 912 in a horizontal plane, and then welding the oil receiving pipe 92. After welding is completed, starting the rotating cylinder 16 again to make the oil pan 9 in a horizontal state, the oil pan fixing cylinder 32 loosens the oil pan 9, removes the welded oil pan 9, and installs the new oil pan 9 to be welded.

[0037] The welding of the oil drain port 91 and the oil receiving pipe 92 is achieved by clamping once, which reduces the preparation time for welding and improves the efficiency of welding.
