[0037] The working principle of this utility model is as follows: The surfaces of the workbench 100 and the flipping frame body 1 are cleaned to remove iron filings, dirt, dust, etc., ensuring that there are no foreign objects between the platform and the workpiece; the workbench 100 is adjusted to the exhaust and depressurization state by the air pressure switch, the pull rod 62 of the first clamping cylinder 61 is pulled down, the swing arm 63 is raised upward, and the first telescopic cylinder 72 is retracted; the connecting bracket 1c is first placed on the first positioning boss 10 of the workbench 10, and the U-shaped surface of the first positioning boss 10 is used to connect the inner side of the connecting bracket 1c. The upper and lower surfaces are limited, and then the quick-connect positioning pin 11 is inserted by aligning the first positioning hole 10a and the bracket hole 1cc. The inner side of the connecting bracket 1c is tightly against the first positioning boss 10 to limit the front and rear of the connecting bracket 1c. Then, the crossbeam 1a and the longitudinal beam 1b are placed directly above the second, third, and fourth positioning bosses 20, 30, and 40 respectively. The air pressure switch is turned on, and the worktable 100 is adjusted to the air intake and pressurization state. The pull rod 62 of the first clamping cylinder 61 rises, and the swing arm 63 presses down to restrict the upper surface of the crossbeam 1a. The first extension... The retractor rod of the first telescopic cylinder 72 moves outward, fixing the crossbeam 1a and longitudinal beam 1b to the first, second, third, fourth, and fifth positioning bosses 10, 20, 30, 40, and 50 via the first positioning block 73 in front of the first telescopic cylinder 72, preventing them from moving. After the crossbeam 1a, longitudinal beam 1b, and connecting bracket 1c are clamped, the connection points of the crossbeam 1a and longitudinal beam 1b, and the connection points of the crossbeam 1a and connecting bracket 1c are welded to form a whole. The connecting bracket 1c is clamped and fixed, so during the welding process, the three will not deform or misalign due to factors such as welding heat, and the concentricity of the connecting bracket 1c can be guaranteed. After welding and fixing, the quick-connect positioning pin 11 is removed, and the two sides of the connecting bracket c are welded. After cooling and shaping, the worktable 100 is adjusted to the depressurization state by the air pressure switch. The pull rod 62 of the first clamping cylinder 61 is pulled down, the swing arm 63 is raised upward, the first telescopic cylinder 72 is retracted, the workpiece is released, and the welded flipping frame assembly 1 is taken out vertically upward.
