The specific implementation of this utility model is described in more detail below with reference to specific embodiments: like Figures 1 to 6 As shown, this embodiment of the utility model provides a special vehicle door welding device, including a base plate 1, multiple support limiting blocks 2, multiple first locking components 3, an angle adjuster assembly 4, and multiple second locking components 5. The base plate 1 is horizontally arranged; the multiple support limiting blocks 2 are detachably connected to the base plate 1 for limiting the vehicle door; the first locking components 3 are detachably connected to the base plate 1 for clamping the vehicle door; the angle adjuster assembly 4 is connected to the base plate 1 and has an inclined mounting surface with a preset angle to the base plate 1; the second locking components 5 are detachably connected to the inclined mounting surface for clamping the vehicle door. Specifically, this embodiment achieves multi-functional integration through modular design, enabling both horizontal clamping and angle-adjustable clamping. The independent design of the angle adjuster assembly allows the door to be fixed in the optimal welding position, and the detachable connection method improves the adaptability and adjustability of the equipment.

[0027] In one optional implementation of this embodiment, the first locking member 3 includes a frame base 31, a first pin 32, a frame body assembly 33, and a locking member 34. The frame base 31 is detachably connected to the base plate 1. The first pin 32 is rotatably connected to the frame body assembly 33 and the frame base 31. The locking member 34 is connected to the frame body assembly 33 and is used to clamp the vehicle door. Specifically, the rotatable connection of the first pin allows the frame body to be angled to adapt to different shaped doors.

[0028] In one optional embodiment of this invention, the locking component 34 includes a locking rod 341, a locking handle 342, a fixing block 343, a connecting plate 344, and a connecting rod 345. The fixing block 343 is fixedly connected to the frame body assembly 33. The locking rod 341 is slidably connected to the fixing block 343 and the frame body assembly 33. One end of the connecting rod 345 is rotatably connected to the fixing block 343, and the other end is rotatably connected to the locking handle 342. One end of the connecting plate 344 is rotatably connected to the locking handle 342, and the other end is rotatably connected to the locking rod 341.

The base 41 is connected to the base plate 1, and the damping shaft 42 is rotatably connected to the mounting plate and the base 41. The mounting plate 43 has an inclined mounting surface. Specifically, the damping shaft is a shaft with significant damping; a rubber layer can be provided on the outer periphery of the shaft to increase rotational damping. The design of the damping shaft ensures stability after angle adjustment, preventing displacement during welding. Precise angle adjustment ensures the welding surface is in the optimal operating position. The independent angle adjuster design facilitates maintenance and replacement.

[0034] As one optional implementation of this embodiment, the preset angle is ±30°. Specifically, the ±30° adjustment range covers most door welding angle requirements.

[0035] In one optional implementation of this embodiment, the support limiting block 2 includes a mounting base plate 21 and a limiting plate 22. The mounting base plate 21 is fixedly connected to the limiting plate 22, and the limiting plate 22 is perpendicular to the mounting base plate 21.

The third base plate assembly 14 has a second oblong hole 141, through which bolts pass to securely connect the third base plate assembly 14 and the first base plate assembly 12. The first oblong hole 131 is set in the vertical direction, thereby allowing the second base plate assembly 13 to be installed at an adjustable height in the vertical direction. The second oblong hole 141 is set in the horizontal direction, thereby allowing the third base plate assembly 14 to be installed at an adjustable position in the horizontal direction.

[0037] The specific implementation steps of this embodiment are as follows: First, based on the model and size of the door to be welded, plan the layout of each component on the base plate, clean the base plate surface and positioning holes, ensuring no debris affects positioning accuracy. Then, install the support limit blocks, aligning the mounting base plate of the support limit blocks with the positioning holes on the base plate. Secure the support limit blocks with bolts through the positioning holes, and check the verticality of the limit plates with a level to ensure they are perpendicular to the mounting base plate. Align the frame base with the positioning holes on the base plate and initially fix it. Connect the frame body assembly and frame base via the first pin, adjusting the frame body angle to be approximately perpendicular to the door edge. Fix the angle adjuster base to the designated position on the base plate, connecting it to the mounting plate via the damping shaft, and initially set the tilt angle. Install the second locking component on the tilted mounting surface of the angle adjuster assembly, adjusting its position to correspond with the clamping part of the door. Next, gently place the door assembly onto the support limit blocks, ensuring full contact between the door and each limit plate for initial positioning. Operate each of the first locking components in sequence: Move the locking handle to push the locking rod forward via the linkage mechanism, allowing the locking rubber head to slightly contact the edge of the door, without fully locking it. Check the door position for accuracy and make minor adjustments if necessary. Fine-tune the angle adjuster according to the door's design angle, loosen the damping shaft adjustment device, and slowly rotate the mounting plate to the desired angle. Lock the damping shaft and confirm the mounting plate is stable and free from wobbling. Fully tighten the locking handles of each of the first locking components to ensure sufficient clamping force. Operate the second locking component to clamp the tilted part of the door, checking all clamping points to ensure the door is not loose or deformed. Confirm that all parts of the door to be welded are in the optimal operating position, checking that each locking mechanism is secure and the support system is stable and reliable. Operate according to the welding process requirements, carefully observing the device's status to ensure there are no abnormalities. Loosen the clamping device, and then loosen the locking handles in reverse order, first loosening the second locking component, then the first. Remove the welded door assembly and carefully move the door away, avoiding collisions with the device.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
