Place the clamping seat one 13 in the second groove on the upper end face of the sliding seat 12, and connect the clamping seat one 13 to the bottom surface of the second groove using a slide rail. Install the telescopic cylinder two 17 in the middle of the front end face of the sliding seat 12, and fix the telescopic shaft of the telescopic cylinder two 17 to the middle of the front end face of the clamping seat one 13 using a connector. Place the clamping plate one 15 in the first groove on the upper end face of the clamping seat one 13, and connect the clamping plate one 15 to the bottom surface of the first groove using a slide rail.

The rotating motor 29 is fixed to the outer wall of one of the mounting plates 27 with bolts, and the output shaft of the rotating motor 29 is fixedly connected to one end of the rotating shaft 19 using a coupling.

[0058] Work process:

[0059] Preparation: Place the assembled base plate 1 on a stable workbench, ensuring the workbench surface is flat and secure. Connect the power and air supply, and check that all electrical and pneumatic components are working properly, such as rotary motor 16, rotary motor 29, telescopic cylinder 14, telescopic cylinder 27, and telescopic cylinder 30, to ensure there are no safety hazards such as electrical or air leakage.

[0060] Clamping steel structural component 30:

[0061] The fixed clamping mechanism 2 clamps the steel structural component 30 to be welded onto the clamping seat 18 of the fixed clamping mechanism 2 and adjusts its position. The telescopic cylinder 20 is activated, extending its telescopic shaft and driving the clamping plate 23 to slide along the width of the clamping seat 18, clamping the steel structural component 30. Then, the positioning bolt 22 is tightened so that its lower end abuts against the steel structural component 30, further securing the component and preventing it from shaking or shifting during welding.

[0062] Adjusting the clamping mechanism 3: Place another steel structural component 30 to be welded on the clamping seat 13 of the adjusting clamping mechanism 3, then activate the telescopic cylinder 14. The telescopic shaft of the telescopic cylinder 14 extends, driving the clamping plate 15 to slide along the width direction of the clamping seat 13, clamping the steel structural component 30. Finally, tighten the positioning bolt 24 so that the lower end of the positioning bolt 24 abuts against the steel structural component 30, completing the fixation of the steel structural component 30. If necessary, activate the telescopic cylinder 17. The telescopic shaft of the telescopic cylinder 17 extends or retracts, driving the clamping seat 13 to slide along the width direction of the sliding seat 12, adjusting the position of the clamping seat 13, and calibrating the welding position of the two steel structural components 30 to be welded.

[0063] Angle Adjustment: Based on the angle requirements of the steel structural component 30 to be welded, start the rotary motor 6. The output shaft of the rotary motor 6 drives the rotating shaft to rotate via a coupling, which in turn drives the adjusting plate 7 to rotate around the rotating shaft. During rotation, the sliding pins 9 at the left ends of the front and rear end faces of the adjusting plate 7 slide within the sliding grooves 11 on the limiting plate 8, limiting the rotation range of the adjusting plate 7 and ensuring rotational stability. When the adjusting plate 7 has rotated to the appropriate angle, turn off the rotary motor 6. If angle adjustment is not required, proceed directly to position adjustment.

[0064] Position Adjustment: Start the rotating motor 29 as needed to adjust the position of the other steel structural component 30 to be welded on the adjusting clamping mechanism 3. The output shaft of the rotating motor 29 drives the rotating shaft 19 to rotate via a coupling, which in turn drives the gear 28 to rotate. The gear 28 meshes with the rack 26 on the lower end face of the sliding seat 12, driving the sliding seat 12 to slide within the sliding groove 25, thereby adjusting the position of the clamping assembly 1 so that the welding joints of the two steel structural components 30 to be welded contact, ready for welding operations.

[0065] Welding Operation: After completing the above preparations, operators can use welding equipment to perform welding operations on the steel structural components. During the welding process, close monitoring of the welding situation is essential to ensure welding quality.

[0066] After the welding operation is completed, an inspection is carried out. If the welding does not meet the requirements, it is re-welded. If the welding meets the requirements, the above steps are repeated in reverse. The welded steel structure component 30 is taken out and the device is returned to its initial position to facilitate the next welding operation.

[0067] The welding combination fixture of this utility model solves the problem that existing welding fixtures cannot flexibly adjust the clamping angle, improves the efficiency and quality of steel structure welding, and reduces the labor intensity and operation difficulty of operators.
