[0041] The working principle of this utility model is as follows: The surfaces of the workbench 100 and the edge component body 1 are cleaned to remove iron filings, dirt, dust, etc., ensuring no foreign objects are present between the platform and the workpiece; the workbench 100 is adjusted to a depressurized state via a pneumatic switch, with each cylinder in a state where the support arm is raised and rotating outwards; the pneumatic switch is first turned on, the first movable cylinder 12 extends outwards, and the first L-shaped positioning block 11 on the first movable cylinder 12 moves synchronously to the outside; then the edge component body 1 is placed in, with the bottom of the edge component body 1 placed on the second positioning block 20. Align the left and right sides of the main body 1 with the first L-shaped positioning blocks 11 to fix it in place. Place the crossbeam connector 1c (L / R) on top of the third positioning block 30, aligning it with the third positioning pin 31 on the third positioning block 30 to fix the crossbeam connector 1c horizontally. Finally, align the column connector 1b with the first positioning pin 11a on the first L-shaped positioning block 11 and secure it tightly. Turn on the air pressure switch, and the worktable 100 is adjusted to the air intake and pressurization state. The arms of the first clamping cylinder 40 and the second clamping cylinder 50 press down and rotate inward to the top of the side component main body 1, while retracting downward to press down on each component. On the upper surface of the component, the column connecting piece 1b and the side column connecting piece 1a are both horizontally and vertically fixed, preventing them from moving. The air pressure switch is turned on, and the worktable 100 is adjusted to the air intake and pressurization state. The arm of the third clamping cylinder 60 presses down and rotates inward to above the crossbeam connecting piece 1c, then retracts downward to press the crossbeam connecting piece 1c onto the third positioning block 30, fixing it in all directions. After the side column connecting piece 1a, column connecting piece 1b, and crossbeam connecting piece 1c (L / R) are clamped, the connection points between the side column connecting piece 1a and column connecting piece 1b, and between the side column connecting piece 1a and crossbeam connecting piece 1c... Welding is performed at the joints of c, and the three parts are welded into a whole. Since the edge component body 1 is clamped and fixed, the three parts will not deform or misalign due to welding heat or other factors during the welding process. After welding and fixing, the air pressure switches are turned on in sequence to adjust the worktable 100 to the depressurization state. The first clamping cylinder 40, the second clamping cylinder 50, and the third clamping cylinder 60 pull rods rise and rotate outward, the first movable cylinder 12 retracts inward, and the first L-shaped positioning block 11 retracts inward simultaneously, releasing the workpiece. The welded edge component body 1 is then taken out vertically upward. Supplement: The edge component body 1 of this utility model is divided into left and right parts. When welding the right edge component body 1, it is only necessary to align the column connecting piece 1b with the first positioning pin 11a on the right first L-shaped positioning block 11 and weld it.
