The control component 10 can be a control handle or a control button to control the working states of the back-pushing cylinder 72, the positioning cylinder 76, the limiting cylinder 80 and the supporting cylinder 82, so as to facilitate workers to quickly limit the part one 12, the part two 13, the part three 14 and the part four 15 to the cross beam 11.

[0030] The shuttle beam 11 welding station of this embodiment can quickly position each part at the end of the beam 11 through the cooperation of multiple cylinders in the positioning mechanism 7. The operation is simple and fast, the positioning and clamping are rapid. Moreover, by cooperating with the flipping mechanism 5 to flip the two mounting seats 6, the welding work and the loading and unloading work can be carried out simultaneously at two stations, greatly improving the welding efficiency.

[0031] As Figure 2 shown, the flipping mechanism 5 includes two brackets 51 vertically fixed to both ends of the base 1 respectively. A rotating shaft 53 is rotatably connected between the two brackets 51. One end of the rotating shaft 53 is connected to the flipping motor 52.

[0032] As Figure 3As shown in FIGS. -5, the back-pushing unit includes a back-pushing cylinder 72 and a back-pushing plate 74. The back-pushing cylinder 72 is fixed to the bottom plate 71 and is used to drive the back-pushing plate 74 to move. Two fixing plates are provided on the back-pushing plate 74, and the fixing plates are fixed to the parts. A slider is provided at the bottom of the back-pushing plate 74, and the slider is slidably engaged with a guide rail 73. The guide rail 73 is fixed to the bottom plate 71. The two fixing plates respectively fix part three 14 and part four 15, and position part three 14 and part four 15 to the back of the cross beam 11. The positioning unit includes a positioning frame 75. The positioning frame 75 is fixed to the bottom plate 71 and a positioning cylinder 76 is provided at the top. The positioning cylinder 76 drives the positioning plate 77 to move. A locking pin 79 is provided on the side of the positioning plate 77 facing part one 12. The locking pin 79 confines part two 13 to the positioning plate 77 and is positioned by the positioning cylinder 76 to the end of the cross beam 11. The limiting unit includes a limiting frame 78. The limiting frame 78 is fixed to the bottom plate 71 and a limiting cylinder 80 is provided at the top. The limiting cylinder 80 drives the limiting plate 81 to move. A locking pin 79 is provided on the side of the limiting frame 78 facing part one 12. The limiting plate 81 presses the part against the limiting frame 78. The locking pin 79 confines part one 12 to the limiting frame 78, and the limiting cylinder 80 rotates the limiting plate 81 to press part one 12 against the limiting frame 78. A supporting cylinder 82 is provided at the bottom of the bottom plate 71. The piston rod of the supporting cylinder 82 passes through the bottom plate 71 upward and is fixed to a supporting block 83. The supporting block 83 is used to support the cross beam 11. A pressing block 84 is provided on the limiting frame 78, and the pressing block 84 cooperates with the supporting block 83 to clamp the cross beam 11.

[0033] Wherein, the positions of the two bottom plates 71 on the mounting base 6 are adjusted according to the length of the cross beam 11, and then the two ends of the cross beam 11 are clamped by the two positioning frames 75, and the positioning and fixing of the cross beam 11 are realized by cooperating with the pressing block 84 and the supporting block 83.

[0034] Working principle: First, the worker adjusts the position of the bottom plate 71 on the mounting base 6 according to the length of the cross beam 11, so that the two positioning frames 75 clamp the two ends of the cross beam 11. Then the worker confines part one 12 to the limiting frame 78, fixes part two 13 to the positioning plate 77, and fixes part three 14 and part four 15 to the fixing plates. Then the worker controls the back-pushing cylinder 72 through the control component 10 to push part three 14 and part four 15 to abut against the back of the cross beam 11 in sequence, and the limiting cylinder 80 clamps part one 12 between the limiting plate 81 and the limiting frame 78. At this time, the bottom of part one 12 abuts against the upper end face of the cross beam 11, and the positioning cylinder 76 pushes part two 13 to the end of the cross beam 11. At this time, the feeding is completed. The turning mechanism 5 works, so that the mounted mounting base 6 rotates 180 degrees, moves into the enclosure 9, and welding is carried out. At the same time, the mounted mounting base 6 of the welded shuttle cross beam 11 is moved out of the enclosure 9. The worker loosens the cross beam 11 through the control component 10, first unloads the materials, and then feeds new cross beams 11 and parts.
