[0031] Working principle: Install the middle part of the workpiece on the positioning plate 13, and control the positioning plate 13 to clamp and fix it through the fixed cylinder two 12. Install the side part of the workpiece on the fixed plate 10, control the fixed plate 10 to clamp through the fixed cylinder one 9, and control the clamping mounting bracket 8 to move through the clamping cylinder one 7, that is, control the docking of different parts of the workpiece.

[0032] Furthermore, control the positioning mounting seat 11 to turn over through the turning motor 2 to make the workpiece in a vertical form. When the motor one 3 works, the lead screw one 4 rotates, that is, the sliding seat one 5 slides, and the surface defects of the welding areas of different parts can be inspected by the inspection mechanism two. Specifically, the orientations of the welding mechanism and the processing mechanism can be controlled through the angle motor 6.

Furthermore, control the angle of the welding processing cylinder 28 through the welding angle motor 27 to perform welding processing on the docked parts.

[0034] After completing the welding operation, check the perpendicularity after welding. Specifically, when the pushing cylinder 41 works, the pushing cylinder 42 moves and approaches the side part. When the pushing motor 43 works, the pushing plate 44 rotates, that is, the end face pushing part 4402 pushes the end face outer cylinder 45, and the circumferential pushing part 4401 pushes the circumferential outer cylinder 48, so that the end face inner cylinder 46 contacts the side part, and the inspection moving frame 40 contacts the middle part. Then control the inspection moving frame 40 to move, and the end face inner cylinder 46 and the circumferential inner cylinder 50 move in the contact area. According to the moving track, the displacement sensor outputs and feeds back the telescopic displacements of the end face inner cylinder 46 and the circumferential inner cylinder 50 to check the perpendicularity information of the side part and the middle part; furthermore, the pushing cylinder 41 can also be used to control the pushing cylinder 42 to move, and the pushing cylinder 42 pushes the side part, that is, applies a preset thrust to check the welding strength.
