The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] A multi-segment puppet welding device for the engine compartment of a white body, such as Figure 1 As shown, it includes cable assembly 1, resistance spot welding gun 2 and switching assembly 3.

[0024] Specifically, such as Figures 1 to 3 As shown, the cable assembly 1 includes a first cable 11 and a second cable 12. The two ends of the first cable 11 and the second cable 12 are respectively connected to an external welding gun and a resistance spot welding gun 2. An insulating pad is provided between the first cable 11 and the second cable 12, which are respectively connected to the external welding gun. The external welding gun and the resistance spot welding gun 2 are electrically connected through the first cable 11 and the second cable 12, allowing the current from the external welding gun to flow into the resistance spot welding gun 2. The insulating pad ensures the safety of the electrical connection between the first cable 11 and the second cable 12 and the external welding gun.

[0025] Specifically, the switching component 3 includes a first switching mechanism 31 and a second switching mechanism 32. The first switching mechanism 31 and the second switching mechanism 32 are movably connected. The first switching mechanism 31 is used to change the position of the second switching mechanism 32. The first switching mechanism 31 includes a first fixed base 311, a first slide rail 312, a first slider 313, a first cylinder 314, and a first connecting base 315. The first cylinder 314 is connected to the base 4 through the first fixed base 311. The output end of the first cylinder 314 is connected to the first connecting base 315. The base 4 has the first slide rail 312 on opposite sides. The first slider 313 is provided on the first slide rail 312. The first slider 313 is connected to the first connecting base 315. The first connecting base 315 is connected to the second switching mechanism 32. The first switching mechanism 31 further includes multiple first limiting blocks 317, multiple second limiting blocks 318, and multiple first limiting connecting blocks 316. The multiple first limiting connecting blocks 316 are mounted on the base 4 and adjacent to the two first slide rails 312. First limiting blocks 317 are mounted on the first limiting connecting blocks 316, and multiple second limiting blocks 318 are mounted on opposite sides of the first connecting seat 315. The positions of the first limiting blocks 317 and the second limiting blocks 318 correspond. The first connecting seat 315 is driven by the extension and retraction of the output end of the first cylinder 314, causing the first slider 313 to move along the first slide rail 312. During the movement, the second limiting blocks 318 gradually move closer to the first limiting blocks 317 in the direction of movement, thereby limiting the movement range and enabling the second switching mechanism 32 connected to the first connecting seat 315 to move within the defined movement range.

[0026] Specifically, the resistance spot welding gun 2 is mounted on the second switching mechanism 32, which is used to change the position of the resistance spot welding gun 2. The second switching mechanism 32 includes a second fixed base 321, a second slide rail 322, a second slider 323, a second cylinder 324, and a second connecting base 325. The second fixed base 321 is connected to the first connecting base 315. The second cylinder 324 is fixed on the second fixed base 321, and its output end is connected to the second connecting base 325. The second slide rail 322 is provided on opposite sides of the first connecting base 315. The second slider 323 is mounted on the second slide rail 322 and is connected to the second connecting base 325. The resistance spot welding gun 2 is mounted on the second connecting base 325. The second switching mechanism 32 also includes multiple third limiting blocks 327, multiple fourth limiting blocks 328, and multiple second limiting connecting blocks 326. The multiple second limiting connecting blocks 326 are disposed on the first connecting seat 315 and adjacent to the two second slide rails 322. Third limiting blocks 327 are disposed on the second limiting connecting blocks 326, and multiple fourth limiting blocks 328 are disposed on opposite sides of the second connecting seat 325. The positions of the third limiting blocks 327 and the fourth limiting blocks 328 correspond. The second connecting seat 325 is driven by the extension and retraction of the output end of the second cylinder 324, causing the second slider 323 to move along the second slide rail 322. During the movement, the fourth limiting blocks 328 gradually approach the third limiting blocks 327 in the direction of movement, thereby limiting the movement range and enabling the resistance spot welding gun 2 connected to the second connecting seat 325 to move within the defined movement range.

[0027] Specifically, the first cylinder 314, the second cylinder 324, and the resistance spot welding gun 2 are respectively connected to a control terminal (not shown), which is located on one side of the base 4.

[0028] It should be noted that the movement of the first cylinder 314 and the second cylinder 324 is relatively independent. They can move simultaneously or individually without affecting each other or in any particular order.

[0029] This invention connects an external welding torch to a resistance spot welding torch 2 via a first cable 11 and a second cable 12, allowing current from the external welding torch to flow into the resistance spot welding torch 2. A second switching mechanism 32 is used to change the position of the resistance spot welding torch 2, adjusting it to two welding point positions on the engine compartment assembly. A first switching structure 31 is used to change the position of the second switching mechanism 32, thereby relatively changing the position of the resistance spot welding torch 2 fixed on the second switching mechanism 32, adjusting it to two other welding point positions on the engine compartment assembly, thus achieving welding at all four welding point positions on the engine compartment assembly.
