Currently, in the automobile production process, it is necessary to weld the car base frame and the slide rails, which requires the use of a welding device. However, most of the welding devices currently used are single-function and use manual handheld welding, which is time-consuming and labor-intensive, and is not conducive to ensuring welding effects and efficiency.

Furthermore, most existing seat base welding devices lack the ability to flexibly adjust the welding height and position according to welding requirements. This reduces welding efficiency and effectiveness to a certain extent, hindering welding flexibility.

[0005] 2. Most current seat base welding devices cannot flexibly adjust the welding angle of the welding gun according to welding needs. At the same time, they do not have the function of synchronous air cooling during welding, which to a certain extent reduces the welding effect and is not conducive to ensuring ease of use.

[0006] 3. Most current seat base welding devices fix the base frame by clamping it on a limit plate, which cannot be flexibly adjusted according to disassembly and assembly needs.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention provides a lifting assembly, a transverse translation assembly and a longitudinal translation assembly. With the help of the third motor in the lifting assembly, the transmission wheel is driven by the transmission action of the transmission belt, and the second rotating shaft is rotated to cause the second screw to rotate, so that the lifting block drives the lifting plate to move up and down. At the same time, the dual-axis motor and the fourth motor in the transverse translation assembly and the longitudinal translation assembly are driven to drive the third screw to rotate, so that the moving block drives the moving plate and the welding gun to move left and right, so as to achieve the effect of flexibly adjusting the transverse welding position.

[0021] 2. The present invention provides a welding assembly. Under the action of the electric push rod, the pin and the hose are used to drive the welding gun to adjust the angle. At the same time, the cooling air is blown to the welding position through the air guide plate by the cooling air fan, achieving the purpose of multi-angle welding and synchronous cooling. This solves the problem that most current seat base welding devices cannot flexibly adjust the welding angle and lack the synchronous cooling function, which to some extent reduces the convenience of use and welding effect.

[0022] 3. The present invention provides a clamping assembly. Under the action of the second generator, the driving gear meshes and rotates with the ring gear. The meshing and rotation of the top teeth of the ring gear and the four driven gears drive the four first screws to rotate, thereby driving the clamping block and the anti-slip pad to move closer to or farther from the positioning block, thereby achieving the purpose of clamping or separating the surface of the base frame.

[0023] 4. The present invention uses a rotating assembly, in which the first motor in the rotating assembly works, and with the help of the pulley rotating in the first annular groove, drives the placement table to rotate, and then drives the base frame and the clamped slide rail to rotate for azimuth adjustment, thereby achieving a multi-directional welding effect, thereby solving the problem that most current seat base welding devices cannot drive the base frame to rotate according to welding requirements and cannot achieve multi-directional welding, thereby reducing the diversity of use to a certain extent.

[0048] Then the slide rail 15 can be taken and snapped to the top of the base frame 18, and then the third motor 67 can be controlled by the controller 11 to work, driving the transmission wheel 66 to rotate, and with the help of the transmission belt 65, the two transmission wheels 66 drive the second rotating shaft 64 to rotate, so that the second screw rod 61 rotates, and then the lifting block 68 drives the movable plate 141 to move downward, so that the welding gun 104 is adjusted to the welding height, and then the dual-axis motor 92 can be controlled by the controller 11 to work, drive the third screw rod 93 to rotate, so that the moving block 95 drives the movable plate 141 to move left and right, and then drives the welding gun 104 to move left and right, so as to adjust the left and right welding positions.

[0049] During the welding process, the controller 11 controls the air cooler 106 to operate, and the refrigerated wind is delivered to the welding position through the air guide plate 105 for synchronous cooling. At the same time, according to the welding angle requirements, the controller 11 controls the electric push rod 102 to operate, and with the help of the pin shaft and the hose 103, the welding gun 104 is driven to adjust the angle for multi-angle welding. According to the welding orientation requirements, the controller 11 controls the first motor 33 to operate, drive the placement table 53 to rotate, and then drive the base frame 18 and the slide rail 15 to rotate for orientation adjustment, so as to perform multi-orientation welding.

[0050] After welding is completed, the controller 11 can be used to control the second motor 514 to drive the driving gear 510 to reverse, so that the ring gear 511 drives the driven gear 59 to reverse, and the first rotating shaft 57 drives the first screw rod 54 to reverse, so that the clamping block 55 and the anti-slip pad 56 move backward and separate from the outside of the base frame 18, and then pull upward to remove the base frame 18 and the slide rail 15 formed as one piece after welding.
