[0018] To address the technical problem of weld spatter easily adhering to the guide portion of the headrest rod during welding, this utility model provides a welding fixture for the rear center headrest rod assembly, which can protect the guide portion of the headrest rod during welding.

[0019] It should be noted that the welding fixture for the rear center headrest rod assembly described in this utility model is used for, but is not limited to, purposes. Figure 1 For ease of explanation, the rear center headrest rod shown is only used in this utility model for welding the rear center headrest rod assembly. Figure 1Taking the rear headrest rod as an example, processing other models of headrest rods only requires adaptive adjustments to the arrangement of the positioning unit and the protective unit, as well as the shape of the protective cover, while the working principle remains essentially the same.

[0020] Please see Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the rear center headrest rod assembly welding fixture in the placement state provided in this embodiment of the utility model; Figure 3 This is a schematic diagram of the rear center headrest rod assembly welding fixture in the welding state according to an embodiment of the present invention. The rear center headrest rod assembly welding fixture includes a positioning unit 1 and a protective unit 2.

[0021] See details Figure 4 , Figure 4 yes Figure 2 A schematic diagram of the positioning unit.

[0022] The positioning unit 1 includes a first positioning plate 11, a first support block 12, and a second support block 13. The first positioning plate 11 and the second support block 13 are used to place the first component 100 of the headrest rod, and the first support block 12 and the second support block 13 are used to place the second component 200 of the headrest rod. The part 300 of the first component 100 and the second component 200 that needs to be welded together is placed in the second support block 13. The shape, size, and relative position of the first positioning plate 11, the first support block 12, and the second support block 13 are adapted to the first component 100 and the second component 200. The first positioning plate 11, the first support block 12, and the second support block 13 are respectively formed with grooves or similar structures to accommodate the first component 100 and the second component 200.

[0023] The protective unit 2 includes a first protective device 21, which is detachably connected to the first positioning plate 11 to cover the portion of the first component 100 located within the first positioning plate 11.

One end of the first positioning plate 11 is rotatably connected to the right-angle support 14, and the other end rests on another right-angle support 14. The third cylinder 15 is connected to the first positioning plate 11 to drive the first positioning plate 11 to rotate around the right-angle support 14 so as to remove the headrest rod located in the positioning groove 11.

[0025] As is easily understood, the positioning unit 1 also includes connecting rods and connecting blocks for arranging the first positioning plate 11, the first support block 12, and the second support block 13, as well as a worktable and other structures. The first positioning plate 11, the first support block 12, and the second support block 13 are fixedly installed on the worktable surface via connecting rods or connecting blocks. The right-angle support 14 is also installed on the worktable surface. The third cylinder 15 can be installed on the worktable surface, or a hole can be drilled in the surface as needed to install it in a suitable position.

[0026] See also Figure 5 and Figure 6 , Figure 5 yes Figure 3 A structural schematic diagram of a single-sided protective unit from a certain perspective; Figure 6 yes Figure 3 A structural schematic diagram of the single-sided protection unit from another perspective.

[0027] In some embodiments, the first protective device 21 includes a first flipping mechanism 211 and a first pressing block 212. The first pressing block 212 has a first groove. The first flipping mechanism 211 is connected to the first pressing block 212 to drive the first pressing block 212 to rotate. This allows the first pressing block 212 to flip directly above the first positioning plate 11, contacting the first positioning plate 11 or leaving only a very small gap. The first groove 11 and the first positioning plate 212 enclose a portion of the first component 100.

[0028] Based on the above embodiments, the first tilting mechanism 211 includes a first cylinder 2111, a first connector 2112, a first arm 2113, a first swing arm 2114, and a third support block 2115. The telescopic end of the first cylinder 2111 is fixedly connected to one end of the first connector 2112, the other end of the first connector 2112 is rotatably connected to one end of the first arm 2113, and the other end of the first arm 2113 is fixedly connected to the first pressure block 212. One end of the first swing arm 2114 is fixedly connected to the fixed end of the first cylinder 2111, the other end of the first swing arm 2114 is rotatably connected to one end of the third support block 2115, and the other end of the third support block 2115 is rotatably connected to the middle part of the first arm 2113.

[0029] The first cylinder 2111 drives the first connector 2112 to move up and down, which in turn drives the first pressure block 212 to rotate through the first arm 2113 and the first swing arm 2114.

[0030] In some embodiments, the protective unit 2 further includes a second protective device 22, which includes a second cylinder 221 and a second protective cover 222. The second protective cover 222 has a second groove that is vertically arranged and faces the first component 100. The second cylinder 221 is connected to the second protective cover 222 to drive the second protective cover 222 toward the first component 100, so that a portion of the structure of the first component 100 enters the second groove, thereby providing protection for that portion.

[0031] Based on the above embodiments, the second protective device 22 further includes a baffle 223, which is fixedly connected to the first positioning plate 11 and corresponds to the second protective cover 222. The second protective cover 222 moves toward the baffle 223 and cooperates with the baffle 223 to enclose part of the structure of the first component 100 to achieve better protection.

[0032] In some embodiments, the second protective device 22 further includes a positioning block 224, which has a horizontally arranged third groove. The second cylinder 221 is also connected to the positioning block 224 to drive the positioning block 224 toward the second component 200, so that the two sides of the second component 200 enter the third groove, thereby protecting those sides. Based on the above embodiments, the protective unit 2 includes two first protective devices 21 symmetrically arranged on both sides of the positioning unit 1 and two second protective devices 22 symmetrically arranged on both sides of the positioning unit 1. The two first protective devices 21 and the second protective devices 22 are used to protect the two sides of the first component 100 and the second component 200, respectively. The second protective device 22 can also position the lateral position of the second component 200.

[0033] See you again Figure 4 In some embodiments, the welding fixture for the rear headrest rod assembly further includes a fixing unit 3, which includes two fixing mechanisms 31. The two fixing mechanisms 31 are respectively arranged at both ends of the second support block 13 and are used to fix the first component 100 and the second component 200 in the second support block 13.

[0034] In some embodiments, the fixing mechanism 31 includes a second flipping mechanism 311 and a second pressing block 312. The second flipping mechanism 311 is connected to the second pressing block 312 to drive the second pressing block 312 to rotate above the second support block 13, and cooperates with the second support block 13 to press the first component 100 or the second component 200. The second flipping mechanism 311 may adopt a similar structural form to the first flipping mechanism 211, and the second pressing block 312 has a notch for welding.

[0035] It is easy to understand that in the welding fixture for the headrest rod assembly, all telescopic mechanisms and the first cylinder should ideally be standardized, such as using cylinders or electric push rods.

[0036] Before welding, the first component 100 and the second component 200 are respectively placed in the first positioning plate 11, the first support block 12, and the second support block 13, forming a... Figure 2 As shown in the diagram, the fixing mechanism 31 then operates to press the second pressure block 312 against the first component 100 and the second component 200. The first protective device 21 and the second protective device 22 operate to provide protection for most of the structure of the first component 100 and the second component 200, presenting... Figure 3 The state shown indicates that welding work is underway.
