[0013] The right side panel, left side panel, right angle adjuster assembly, and left angle adjuster assembly described in this manual are named from the perspective of the seat occupant, while the accompanying drawings are drawn from the worker's perspective. Therefore, there is a left-right mirror image difference between the part names and their positions in the accompanying drawings.

[0014] In practice, firstly, as follows: Figure 2 As shown, the worker first assembles the headrest guide sleeve 32 and the upper horizontal tube 33 together to form the upper horizontal tube assembly. The headrest guide sleeve positioning block 8 is used to position the headrest guide sleeve 32, and the upper horizontal tube 33 is also positioned accordingly. The worker then operates the piston rod of the first cylinder 9 to extend, and the first clamping block 10 presses against the upper horizontal tube 33. This, in conjunction with the upper horizontal tube positioning block 7, completes the clamping and positioning of the upper horizontal tube 33. At this point, the upper horizontal tube assembly is clamped. Subsequently, as... Figure 3 As shown, the worker uses the right side plate positioning block 13 to position the right side plate 34. The lower end of the right side plate 34 rests on the side plate support block 17, which also serves a positioning function. The worker operates the piston rod of the second cylinder 11 to extend, and the second clamping block 15 cooperates with the right side plate positioning block 13 to clamp and position the right side plate 34. The worker uses the left side plate positioning block 14 to position the left side plate 35. The lower end of the left side plate 35 also rests on the side plate support block 17. The worker operates the piston rod of the third cylinder 12 to extend, and the third clamping block 16 cooperates with the left side plate positioning block 14 to clamp and position the left side plate 35. At this time, the lower end of the upper horizontal tube 33 is in contact with the right side plate 34 and the left side plate 35 respectively. Subsequently, as... Figure 4 As shown, the worker uses the angle adjuster positioning block 22 to position the right angle adjuster assembly 36, and operates the piston rod of the fourth cylinder 18 to extend, causing the fourth clamping block 20 to press against the right angle adjuster assembly 36, so that its upper end fits against the lower end of the right side plate 34; the worker continues to use the angle adjuster positioning block 22 to position the left angle adjuster assembly 37, and operates the piston rod of the fifth cylinder 19 to extend, causing the fifth clamping block 21 to press against the left angle adjuster assembly 37, so that its upper end fits against the lower end of the left side plate 35. Finally, as... Figure 5 As shown, the worker places the lower horizontal plate 38 on the lower horizontal plate support block 29. The two ends of the lower horizontal plate 38 contact the inner walls of the right angle adjuster assembly 36 and the left angle adjuster assembly 37, respectively. The worker simultaneously extends the piston rods of the sixth cylinder 23 and the seventh cylinder 24, causing the sixth clamping block 25 and the seventh clamping block 26 to press against the lower ends of the right angle adjuster assembly 36 and the left angle adjuster assembly 37 from both sides, making the lower ends of the right angle adjuster assembly 36 and the left angle adjuster assembly 37 fit against the two ends of the lower horizontal plate 38. At this point, all components of the seat frame are clamped. A first welding hole 27 and a second welding hole 28 are respectively made on the back plate 5 at the positions where the right angle adjuster assembly 36 and the lower horizontal plate 38 fit, and at the positions where the left angle adjuster assembly 37 and the lower horizontal plate 38 fit, to prevent obstruction of the workpiece during back welding.

[0015] The turntable 6 of this utility model is placed horizontally, and the rotating part 30 rotates vertically. When used in conjunction with a welding robot, the advantage is that the back plate 5 faces the worker, so the worker does not need to walk around the back plate 5 when loading and clamping materials.

[0016] Workers can operate a welding robot to weld the seat components. After welding is complete, the worker operates the piston rods of each cylinder to retract, and then removes the welded seat frame.

[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the scope of protection of the present utility model.
