Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] See Figures 1 to 3 ,as well as Figure 6 This utility model provides a welding fixture for automotive seat steel wires, comprising: a base 1, a positioning seat 2 disposed on the base 1, and clamping components 3 symmetrically disposed on the positioning seat 2. The clamping components 3 include a support rod 301, a crossbeam 302, a first cylinder 303, and an abutment seat 304.

[0032] The bottom end of the support rod 301 is connected to the positioning seat 2, one end of the crossbeam 302 is connected to the top end of the support rod 301, the fixed end of the first cylinder 303 is connected to the other end of the crossbeam 302, the telescopic end of the first cylinder 303 passes through the crossbeam 302, and the abutment seat 304 is set on the top surface of the positioning seat 2 and is located below the first cylinder 303. The cooperation between the telescopic end of the first cylinder 303 and the abutment seat 304 is used to fix the neck support frame 4. The two ends of the base 1 are provided with opening slots 5, and sliding seats 6 are slidably arranged in the opening slots 5. The top surface of the base 1 is slidably provided with a through groove 7, and a movable seat 8 is slidably arranged in the through groove 7.

[0033] The clamping mechanism consists of multiple sets, which are respectively set on the top surface of the sliding seat 6, the top surface of the movable seat 8, and the top surface of the base 1. The clamping mechanisms on the top surface of the sliding seat 6 and the top surface of the base 1 are used to fix the backrest frame 12, and the clamping mechanism on the top surface of the movable seat 8 is used to fix the reinforcing steel wire 13.

[0034] When the first cylinder 303 is working, its telescopic end moves toward the abutment seat 304. There are four clamping mechanisms: one set of clamping mechanisms is provided on the top surface of each of the two sliding seats 6, the top surface of the movable seat 8, and the top surface of the base 1.

[0035] Specifically, firstly, the fixed end of the neck support frame 4 is placed on the positioning seat 2, between the two support rods 301. The extension end of the first cylinder 303 on the crossbeam 302 is extended. The extension end of the first cylinder 303 cooperates with the abutment seat 304 to fix the fixed end of the neck support frame 4 on the positioning seat 2.

[0036] Then, the side frame of the backrest frame 12 is placed on the clamping mechanism on the top surface of the two sliding seats 6. By adjusting the position of the sliding seats 6 in the opening slot 5, the relative position of the side frame of the backrest frame 12 and the connecting end of the neck support frame 4 is changed. After adjusting to the appropriate position, welding is performed.

[0037] Next, the bottom frame of the backrest frame 12 is placed on the clamping mechanism on the top surface of the base 1, and the side frames of the backrest frame 12 are welded to its bottom frame.

[0038] Finally, the reinforcing steel wire 13 is placed on the clamping mechanism on the movable seat 8. By adjusting the position of the movable seat 8 in the through groove 7, the relative position of the reinforcing steel wire 13 and the side frame of the backrest frame 12 is adjusted and welded. Through the cooperation between the sliding seat 6 and the movable seat 8, the relative position between each frame of the backrest frame 12 is controlled so that the clamping mechanism can adapt to the frames of the backrest frame 12 of different specifications.

[0039] It should be noted that the two sets of clamping components 3 are symmetrically arranged on the positioning seat 2, and the two support rods 301 are positioned on both sides of the abutment seat 304, so that the bending point of the neck support frame 4 is located below the crossbeam 302. The length of the crossbeam 302 and the relative distance between the two support rods 301 can be set as needed so that the two clamping components 3 can accommodate neck support frames 4 of different widths; this application does not limit this. In this embodiment, the connecting end of the neck support frame 4 has been pre-screwed to the top frame of the backrest frame 12.

[0040] In some embodiments, the clamping assembly 3 further includes a connecting rod 305 and a second cylinder 306. The connecting rod 305 is disposed on the top surface of the positioning seat 2, and the fixed end of the second cylinder 306 is connected to the connecting rod 305. The telescopic end of the second cylinder 306 passes through the connecting rod 305. The connecting rod 305 is located on one side of the support rod 301, with its direction away from the neck support frame 4. Preferably, the abutment seat 304 has an inclined surface, and the axis of the telescopic direction of the telescopic end of the second cylinder 306 is perpendicular to the inclined surface of the abutment seat 304. The second cylinder 306 and the first cylinder 303 respectively cooperate with the abutment block 17. By applying two forces in different directions to the neck support frame 4, the neck support frame 4 is more firmly abutted against the abutment block 17 when the first cylinder 303 and the second cylinder 306 are working, thereby fixing it to the positioning seat 2.

[0041] In some embodiments, the clamping mechanism includes two sets of clamping components 9 arranged opposite each other, with a limiting block 11 disposed between the two sets of clamping components 9. The limiting block 11 is used to limit the bottom of the backrest frame 12, increasing the stability of the clamping components 9 clamping the backrest frame 12.

[0042] See Figure 4 , Figure 5 and Figure 7 In some embodiments, the clamping assembly 9 includes a fixed base 901, a third cylinder 902, a clamping rod 903, and a fixed frame 904. The fixed base 901 is used to connect with the sliding base 6, the movable base 8, or the base 1. The fixed end of the third cylinder 902 is disposed in the fixed base 901, and the telescopic end of the third cylinder 902 extends out of the fixed base 901 and is hinged to the bottom end of the clamping rod 903. The middle section of the clamping rod 903 is hinged to the fixed frame 904 through a hinge piece 10. The fixed frame 904 is disposed on the top surface of the fixed base 901.

[0043] Specifically, the telescopic end of the third cylinder 902 extends, causing the bottom of the clamping rod 903 to move upward. The top of the clamping rod 903 is subjected to the upward force of the bottom of the clamping rod 903 and the force of the hinge piece 10, causing the top of the clamping rod 903 to move towards the limiting block 11. Both clamping rods 903 rotate relative to each other towards the limiting block 11 and cooperate with the limiting block 11 to fix the frame of the backrest frame 12.

[0044] It should be noted that, for ease of viewing, the opening directions of the two opposing fixed seats 901 in the two sets of opposing clamping components 9 in the attached figure are not the same. However, in actual use, the opening directions of the fixed seats 901 can also be set to be the same, as long as the rotation directions of the two opposing clamping rods 903 in the clamping mechanism are opposite.

[0045] In some embodiments, one of the two clamping rods 903 of the clamping mechanism is provided with a male clamping member 14, and the other clamping rod 903 is provided with a female clamping member 15. Further, the female clamping member 15 is provided with a groove 16, and the male clamping member 14 has a protrusion corresponding to the groove 16. When the male clamping member 14 and the female clamping member 15 are clamped, the male clamping member 14 is engaged in the groove 16. When the clamping mechanism is working, the male clamping member 14 is engaged in the groove 16, and the two clamping rods 903 are mutually restrained axially in the rotation direction, making the clamping mechanism more secure when clamping the backrest frame 12.

[0046] In some embodiments, an abutment block 17 is provided on the telescopic end of the first cylinder 303. Preferably, a first rubber pad is provided on the abutment surface of the abutment block 17 and the neck support frame 4 to increase the friction between the first cylinder 303 and the neck support frame 4.

[0047] In some embodiments, a pressure block 18 is provided on the telescopic end of the second cylinder 306. Preferably, a second rubber pad is provided on the contact surface between the pressure block 18 and the backrest frame 12 to increase the friction between the second cylinder 306 and the backrest frame 12.

[0048] In some embodiments, each of the opposite sidewalls of the opening slot 5 is provided with a first sliding groove 19, and each of the opposite sidewalls of the sliding seat 6 is provided with a first slider 20. The first slider 20 slides within the first sliding groove 19, and the sliding seat 6 is slidably connected to the opening slot 5 via the first slider 20. Further, each of the opposite sidewalls of the through slot 7 is provided with a second sliding groove 21, and each of the opposite sidewalls of the movable seat 8 is provided with a second slider 22. The second slider 22 slides within the second sliding groove 21, and the movable seat 8 is slidably connected to the through slot 7 via the second slider 22.

[0049] The cooperation between the first slider 20 and the first slide groove 19 makes the sliding seat 6 slide more stably in the opening groove 5. The cooperation between the second slider 22 and the second slide groove 21 makes the sliding seat 8 slide more stably in the through groove 7.

[0050] It should be noted that the first cylinder 303, the second cylinder 306 and the third cylinder 902 mentioned above are all known components, and their working principles and specific control methods are known to those skilled in the art. This application will not elaborate on them here.

[0051] Work process

[0052] First, place the fixed end of the neck support frame 4 on the positioning seat 2, between the two support rods 301. Control the extension end of the first cylinder 303 on the crossbeam 302 to extend, and the abutment block 17 moves towards the abutment seat 304 under force, with the first rubber pad abutting against the neck support frame 4. Then, control the extension end of the second cylinder 306 to extend, and the pressure block 18 moves towards the abutment seat 304 under force, with the second rubber pad abutting against the neck support frame 4, thus fixing the neck support frame 4 on the positioning seat 2.

[0053] Then, the two side frames of the backrest frame 12 are placed on the limiting blocks 11 on the top surfaces of the two sliding seats 6. By adjusting the position of the sliding seats 6 in the opening slots 5, the relative positions of the side frames of the backrest frame 12 and the neck support frame 4 are changed. After adjusting to the appropriate position, the two sets of third cylinders 902 are activated. One of the third cylinders 902 extends its telescopic end, driving the bottom of the clamping rod 903 to move upward. The top of the clamping rod 903 is subjected to the force of the upward movement of the bottom of the clamping rod 903 and the force of the hinge piece 10. The top of the clamping rod 903 moves towards the limiting block 11, and the clamping female part 15 abuts against the side frame of the backrest frame 12. The telescopic end of the other third cylinder 902 extends, and the process is the same. The clamping male part 14 abuts against the side frame of the backrest frame 12 and is inserted into the groove 16 of the clamping female part 15. The clamping mechanism fixes the side frame of the backrest frame 12. Weld the side frames of the backrest frame 12 and the top frame of the backrest frame 12 that are screwed onto the neck support frame 4.

[0054] Next, the bottom frame of the backrest frame 12 is placed on the limiting block 11 on the top surface of the base 1, and the process is the same as above. The clamping mechanism fixes the bottom frame of the backrest frame 12 and welds the side frame of the backrest frame 12 to its bottom frame.

[0055] Finally, the reinforcing steel wire 13 is placed on the limiting block 11 on the movable seat 8, and the process is the same as above. The clamping mechanism fixes the reinforcing steel wire 13. By adjusting the position of the movable seat 8 in the through groove 7, the relative position of the reinforcing steel wire 13 and the two side frames of the backrest frame 12 are adjusted and welded.

[0056] By cooperating with each other, the sliding seat 6 and the movable seat 8 control the relative positions between the various frames of the backrest frame 12 so that the clamping mechanism can adapt to the frames of the backrest frame 12 of different specifications.
