A slider is arranged at the bottom of the second stop plate 15, and the slider cooperates with the slide groove 5 to realize the sliding connection between the second stop plate 15 and the base along the length direction of the long hole 2. A second locking plate 16 is also arranged at the bottom of the second stop plate 15, and second locking bolts 13 pass through both ends of the second locking plate 16.

[0045] Furthermore, two second horizontal telescopic components are provided at the end of the long hole 2, one of the second horizontal telescopic components corresponds to one of the curved steels in the double beam, and the other second horizontal telescopic component corresponds to the other curved steel in the double beam.

[0050] One end of the double beam 11 abuts against the second stop plate 15, and the piston rod of the second horizontal cylinder 17 extends to apply pressure to the other end of the double beam 11, cooperating with the second stop plate 15 to position the double beam 11 along the length direction.

[0051] The upper surface of the support beam 3 is also provided with a plurality of rotating vertical telescopic components, which adopt the existing rotating telescopic cylinder 20, whose piston rod can output both rotation around its own axis and linear motion along its own axis. The rotating telescopic cylinder can adopt existing equipment, and its specific structure will not be described in detail here.

[0052] The piston rod of the rotary telescopic cylinder 20 is connected with a pressing component, which is used to apply downward pressure to the top surface of the double beams. The pressing component cooperates with the support member to position the double beams vertically.

[0053] The pressing component includes a pressing beam 21, which is vertically connected to the piston rod of the rotating telescopic cylinder 20. The end of the pressing beam 21 is threadedly connected with a pressing piece. The pressing piece adopts a pressing bolt 22.

[0058] When the double beam 11 is swung, the rotating telescopic cylinder 20 drives the pressing beam 21 to rotate to the position where the pressing bolt 22 leaves the upper part of the long hole 2, so that the two curved steels of the double beam 11 can be swung.

[0059] The first horizontal cylinder 12, the second horizontal cylinder 27 and the rotating telescopic cylinder 20 are controlled by the control valve group 23. The first horizontal cylinder 12 applies pressure to the side of the double beam 11, and together with the first stop plate 6, the double beam 11 is positioned and fixed in the width direction. The second horizontal cylinder 17 applies pressure to the end of the double beam 11, and together with the second stop plate 15, the double beam 11 is positioned and fixed in the length direction. The rotating telescopic cylinder 20 drives the downward pressure bolt 22 to rotate to the top of the double beam 11, and moves downward to press on the upper surface of the double beam 11, and works together with the support plate 6 to position and fix the double beam 11 in the vertical direction.

[0060] The passenger car double-beam full-position welding tooling of this embodiment uses three cylinders to quickly clamp and release the double-beam, realizing semi-automatic operation, reducing manual intervention, reducing employee labor intensity, and improving production efficiency. It can ensure the assembly accuracy of the two beams of the double-beam, avoid the problems of splicing gap and upper flatness exceeding the tolerance of the two beams, and reduce the probability of rework. At the same time, when using it, the staff only needs to place the curved steel in batches without the need for assembly and spot welding, thereby improving welding consistency and production efficiency.

[0062] The present embodiment provides a passenger car double-beam all-position welding system, comprising a welding robot and the passenger car double-beam all-position welding tooling described in Example 1, and also comprising a flipping device, which is fixedly connected to the passenger car double-beam all-position welding tooling to drive the passenger car double-beam all-position welding tooling to flip.

[0063] The welding robot and the flipping device can use existing equipment, and their specific structures are not described in detail here. The base of the full-position welding tool is fixed relative to the flipping device by a bolt to ensure the benchmark consistency between the tool and the flipping device, and the benchmark deviation is not greater than 0.1mm.

[0064] The flipping device drives the all-position welding tooling to flip, and cooperates with the welding robot to perform interval welding on the two curved arc steels of the double parallel beams. Through program setting, the welding position of the welding robot avoids the contact position between the support plate and the double parallel beams.
