[0028] Specifically, the positioning assembly 2 further comprises a support seat 8 arranged on the workbench 1, and a positioning block 9 connected to the support seat 8, wherein the positioning groove 3 and the positioning part 4 are arranged on the positioning block 9.

[0029] In order to provide a limit for the part, the support seat 8 is further provided with a first limiting block 10 and a second limiting block 11, the support seat 8 is provided with two first limiting blocks 10, and the second limiting block 11 is located between the first limiting block 10 and the positioning block 9, the first limiting block 10 and the second limiting block 11 are used together to provide a limit for the part.

[0030] Specifically, the first limiting block 10 is provided with a plurality of threaded holes 12, and the bolts are connected to the support seat 8 through the threaded holes 12, the first limiting block 10 is further provided with a first clamping groove 13, one side of the part is clamped in the first clamping groove 13, and the positions at which the two first limiting blocks 10 are connected to the support seat 8 can be adjusted according to the size of the part by making the bolts pass through different threaded holes 12, specifically, by making the bolts pass through different threaded holes 12, the position of the first limiting block 10 relative to the support seat 8 can be changed, thereby adapting to parts of different sizes, this design allows the user to flexibly adjust the position of the first limiting block 10 according to actual needs, ensuring accurate positioning of the part on the workbench 1.

[0031] Specifically, the second limiting block 11 is provided with an elongated slot, the bolts pass through the elongated slot and are threadedly connected to the support seat 8, the second limiting block 11 is further provided with a second clamping groove 15, the other side of the part is clamped in the second clamping groove 15, and the position at which the second limiting block 11 is connected to the support seat 8 can be adjusted within the range of the elongated slot by loosening or tightening the bolts, so as to adapt to parts of different sizes, ensuring the stability and accuracy of the part during welding, thereby ensuring the quality of welding and the final performance of the product.

[0032] When the part is placed on the worktable 1, one side of the part is first engaged in the first engaging groove 13 of the first limiting block 10 to ensure that the part's position does not shift in this direction. Then, the other side of the part is engaged in the second engaging groove 15 of the second limiting block 11 to further restrict the movement of the part in another direction. In addition, both ends of the part are placed on both sides of the protrusion 5 of the positioning part 4. This not only ensures that the part is accurately positioned, but also prevents the part from rotating or sliding during the welding process. Through the double limiting effect of the first limiting block 10 and the second limiting block 11, plus the support of the protrusion 5 of the positioning part 4 for both ends of the part, the position of the part on the entire worktable 1 is precisely fixed, thereby ensuring the quality and accuracy of the welding.

[0033] In order to drive the fixed block 7 to rise and fall, the fixed assembly 6 also includes a drive component 16, which is set on the worktable 1. The fixed block 7 is connected to the output end of the drive component 16. The drive component 16 is used to drive the fixed block 7 to rise and fall. The drive component 16 can be a hydraulic cylinder, a pneumatic cylinder or a motor.

[0034] In order to provide support for the linear section 20, a number of support blocks 17 are also provided on the worktable 1. The support blocks 17 are evenly distributed on both sides of the drive member 16. Each support block 17 is provided with a support groove 18. The linear section 20 is placed on the support groove 18, and the support groove 18 is used to provide support for the linear section 20.

[0035] When the headrest support rod is placed on the workbench 1, one end of the bent part 19 is placed in the positioning groove 3 on the positioning block 9 to ensure that the position of the bent part 19 is accurate. At the same time, the straight part 20 is placed in the support groove 18 on the support block 17. The support groove 18 can provide stable support for the straight part 20. Subsequently, the fixing block 7 moves downward under the drive of the drive member 16 and abuts against the straight part 20. Specifically, after the drive member 16 is started, the fixing block 7 moves downward in the vertical direction until it is in close contact with the straight part 20. In this way, the fixing block 7 can not only ensure that the position of the headrest support rod is accurate during the welding process, but also effectively prevent the headrest support rod from rotating or sliding during the welding process.
