[0020] The present invention will now be described in detail with reference to specific embodiments:

[0021] like Figures 1 to 5 The fixture shown is for welding and positioning stiffeners and base plates. It includes a platform 1, on which an array of clamping mechanisms are equidistantly arranged. Each clamping mechanism consists of a fixed clamping block 2, a movable clamping block 3, and a telescopic cylinder 4. The fixed clamping block 2 and the cylinder body of the telescopic cylinder 4 are fixedly installed on the platform 1, and the movable clamping block 3 is fixedly installed on the piston rod of the telescopic cylinder 4.

[0022] The clamping mechanism also includes a base 5, a clamping plate 6, and a support plate 7. The base 5 is fixedly installed on the platform 1, and the fixing clamp 2 is fixedly installed on the base 5. The clamping plate 6 and the support plate 7 are both screwed and fixedly installed on the base 5. The height of the support plate 7 is lower than the height of the clamping plate 6. The clamping plate 6, the support plate 7, and the base 5 form a slot. The stiffening plate 10 is placed in the slot. The support plate 7 serves as a reference surface to provide precise positioning for the stiffening plate 10.

[0023] The fixed clamping block 2 and the movable clamping block 3 are provided with a first protective gas channel 23 and a second protective gas channel 33, which are sealed at both ends. The fixed clamping block 2 is arranged in a linear array with a first vent 21 connected to the first protective gas channel 23. The movable clamping block 3 is arranged in a linear array with a second vent 31 connected to the second protective gas channel 33. The first protective gas channel 23 and the second protective gas channel 33 are respectively sealed and fixedly connected to the first pipe joint 22 and the second pipe joint 32. Protective gas is delivered to the weld of the stiffening plate 10 and the bottom plate 9 through the first vent 21 and the second vent 31 to avoid oxidation at the weld.

[0024] The outer ends of the first air hole 21 and the second air hole 31 are both inclined toward the slot, which allows the protective air to flow toward the weld of the stiffening plate 10 and the bottom plate 9.

[0025] L-shaped positioning plates 11 are fixedly installed around the platform 1. The L-shaped positioning plates 11 facilitate the clamping and positioning of the base plate to improve the laser welding accuracy.

[0026] One end of the platform 1 is fixedly installed with a positioning block 12 for positioning the base plate 9. One end of the base plate 9 rests against the positioning block 12 to achieve its placement and positioning.

[0027] After all the stiffening plates 10 are placed on the tray 7 in the slot, the piston rod of the telescopic cylinder 4 is activated to extend and push the movable clamping block 3 to cooperate with the fixed clamping block 2 to clamp and fix the stiffening plates 10. After the base plate 9 is positioned on the platform 1, laser welding is performed on the stiffening plates 10 and the base plate 9 at the joints of the base plate 9 and each stiffening plate 10 according to the preset instructions. After the welding is completed, the piston rod of the telescopic cylinder 4 drives the movable clamping block 3 to retract, releasing the clamping force on the stiffening plates 10. The operator then removes the welded assembly of the base plate 9 and the stiffening plates 10.
