[0040] like Figure 1 As shown, this utility model provides a welding fixture for automobile seats, including: a workbench 110, a connecting plate 120, a lower platform plate 130, a limiting mechanism 140, a floating mechanism 150, an upper platform plate 160, a support plate 170, a welding support block 171, a first support block 181, a second support block 182, a welding support platform 183, an auxiliary support 190, and a workpiece to be welded 200.

[0041] The workbench 110 is horizontally positioned, and the connecting plate 120 is fixed to the workbench 110 using T-bolts. The lower platform plate 130 is fixedly mounted on the connecting plate 120. The upper platform plate 160 is spaced apart from the lower platform plate 130 and is located directly above the lower platform plate 130. Between the upper platform plate 160 and the lower platform plate 130, at the four corners of the upper platform plate 160 and the lower platform plate 130, four floating mechanisms 150 and four limiting mechanisms 140 are respectively provided, with the limiting mechanisms 140 located to one side of the floating mechanisms 150. On one side of the upper platform plate 160, at both ends of the upper platform plate 160, auxiliary supports 190 are respectively provided. At the middle position of the upper platform plate 160, a welding support platform 183 is fixedly installed for placing the welding component 200 to be welded to the seat frame. Two first support blocks 181 are respectively supported on both sides of the welding support platform 183, and two second support blocks 182 are respectively located at both ends of the upper platform plate 160, close to the auxiliary support 190. The second support block 182 has a square cross-section and a positioning head is provided at the top.

[0042] A rectangular first through slot is formed in the middle of the lower platform plate 130. Two rectangular second through slots are formed on both sides of the welding support platform 183 on the upper platform plate 160, located above the first through slot. One end of each of the two support plates 170 passes through the first through slot and is fixed to the connecting plate 120. The other ends of the two support plates 170 pass through the second through slots, and a first support block 181 is fixed thereon to support both ends of the workpiece 200 to be welded. A first limiting hole and a second limiting hole are coaxially opposite each other on the upper platform 160 and the lower platform 130, respectively. The diameter of the first limiting hole is larger than the diameter of the second limiting hole, used to house the limiting mechanism 140.

[0043] The floating mechanism 150 includes a support shaft 151, a guide sleeve 152, and a floating spring 153. One end of the guide sleeve 152 passes through the upper platform plate 160 and is fixedly mounted on the upper platform plate 160 via a flange. One end of the support shaft 151 is fixedly mounted on the lower platform plate 130, and the other end is matched and mounted inside the guide sleeve 152, allowing relative movement along the guide sleeve 152. The floating spring 153 is located outside the support shaft 151, with one end abutting against the lower platform plate 130 and the other end abutting against the bottom of the flange.

[0044] In this utility model, as a preferred embodiment, the guide sleeve 152 is a linear bearing.
