[0024] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0025] like Figures 1-2As shown, this utility model provides a dual-station wheel hub welding equipment, including a support platform 1. Welding stations 2 are fixedly connected to the top left and right sides of the support platform 1. The welding station 2 includes a gantry bracket 21. Two gantry brackets 21 are fixedly connected to the top left and right sides of the support platform 1 respectively. A through slot is opened in the middle of the top of the gantry bracket 21. Three through support columns 22 are fixedly connected to the top of the gantry bracket 21 in a ring array. A welding bracket 23 is fixedly connected to the top of the three support columns 22. A positioning bracket 24 is fixedly connected to the bottom of the three support columns 22.

[0026] The support platform 1 serves as the basic load-bearing structure of the entire equipment, providing stable support for the welding stations 2 on both sides. The gantry bracket 21 is fixed on the support platform 1 to form the frame structure of the welding station. The through slot is used to place the wheel hub to be welded for easy operation. The support column 22 connects the welding bracket 23 and the positioning bracket 24, ensuring that the relative positions of the two brackets are fixed in space, providing a stable working platform for subsequent welding operations.

[0027] like Figures 3-4 As shown, this utility model provides a dual-station wheel hub welding device. The welding bracket 23 includes an upper support plate 231, which is fixedly connected to the top of three support columns 22. A cylinder 232 is fixedly connected to the top center of the upper support plate 231. The output end of the cylinder 232 extends through to the bottom of the upper support plate 231 and is fixedly connected to a sliding frame 233. A positioning pressure ring 234 is fixedly connected to the bottom end of the sliding frame 233. Three sliding columns 235 are fixedly connected in a circular array at the top of the sliding frame 233. Each of the three sliding columns 235 extends through to the top of the upper support plate 231 and is fixedly connected to a top plate 236. A welding assembly 237 is fixedly connected to the bottom of the top plate 236. The positioning bracket 232... 4 includes a lower support plate 241, which is fixedly connected to the bottom of three support columns 22. A ring-shaped connecting frame 242 is fixedly connected to the top of the lower support plate 241. A rotating gear ring 243 is rotatably connected to the outer side of the top of the ring-shaped connecting frame 242. A positioning ring 246 is fixedly connected to the inner side of the top of the ring-shaped connecting frame 242. A positioning column 247 that runs vertically through the middle of the lower support plate 241 is fixedly connected. The positioning bracket 24 includes a motor 244, which is fixedly connected to the top of the gantry bracket 21. The output shaft of the motor 244 runs through to the bottom of the gantry bracket 21 and is fixedly connected to a transmission wheel 245. The outer surface of the transmission wheel 245 meshes with the outer surface of the rotating gear ring 243.

[0028] Cylinder 232 is fixed on upper support plate 231. When cylinder 232 works, its output end pushes sliding frame 233 downward, thereby driving positioning pressure ring 234 downward to fix the hub placed on positioning bracket 24 and prevent the hub from moving during welding. The setting of sliding column 235 and top plate 236 allows welding assembly 237 to move up and down with sliding frame 233, while also ensuring the stability of welding assembly 237 during movement. Motor 244 is fixed on top of gantry bracket 21. When motor 244 works, its output shaft drives transmission wheel 245 to rotate. Transmission wheel 245 meshes with rotating gear ring 243, thereby driving rotating gear ring 243 to rotate on annular connecting frame 242. The rotation of rotating gear ring 243 can drive the hub placed on positioning ring 246 and positioning column 247 to rotate, which facilitates welding at different positions of the hub.

[0029] like Figure 5 As shown, this utility model provides a dual-station wheel hub welding device. The welding assembly 237 includes a threaded post 2371, which is fixedly connected to the bottom of the top plate 236. A threaded collar 2372 is threadedly connected to the outer surface of the threaded post 2371. The bottom end of the inner surface of the threaded collar 2372 is rotatably engaged with a limit plate 2373. A square sliding post 2374 is fixedly connected to the top of the limit plate 2373. The outer surface of the square sliding post 2374 is slidably connected to the middle part of the threaded post 2371. A connecting plate 2375 is fixedly connected to the bottom of plate 2373. A knob 2376 is movably connected to the left end of the connecting plate 2375. A transmission screw 2377 is fixedly connected to the right side of the knob 2376. A sliding groove is provided at the bottom of the connecting plate 2375. The right end of the transmission screw 2377 passes through the interior of the sliding groove and is threadedly connected to a threaded slide plate 2378 on its outer surface. The outer surface of the threaded slide plate 2378 is slidably connected to the inner surface of the sliding groove. A welding gun 2379 is fixedly connected to the bottom of the threaded slide plate 2378.

[0030] The threaded post 2371 is fixed to the bottom of the top plate 236. By rotating the threaded collar 2372, the threaded collar 2372 can move up and down along the threaded post 2371 due to the threaded connection. The limiting plate 2373 is rotatably engaged with the threaded collar 2372, and is slidably connected to the threaded post 2371 through the square sliding post 2374, so that the limiting plate 2373 can only move up and down with the threaded collar 2372 and will not rotate. The connecting plate 2375 is fixedly connected to the limiting plate 2373, so it will also move up and down, thereby adjusting the height of the welding gun 2379. When the knob 2376 is turned, the knob 2376 drives the transmission screw 2377 to rotate. The transmission screw 2377 is threadedly connected to the threaded slide plate 2378, and the threaded slide plate 2378 slides in the sliding groove. Therefore, the rotation of the transmission screw 2377 can make the threaded slide plate 2378 move left and right in the sliding groove, thereby adjusting the horizontal position of the welding gun 2379.

[0031] The working principle of this dual-station wheel hub welding equipment will be explained in detail below.

[0032] like Figures 1-5 As shown, firstly, the wheel hub to be welded is placed on the positioning bracket 24 of the left welding station 2, aligning the center hole of the wheel hub with the positioning post 247, and the edge of the wheel hub is placed on the positioning ring 246. The motor 244 of the left welding station 2 is started, and the motor 244 drives the transmission wheel 245 to rotate, which in turn causes the rotating gear ring 243 to slowly rotate the wheel hub, adjusting it to a suitable starting welding position. At the same time, the cylinder 232 is started, and the cylinder 232 pushes the sliding bracket 233 downward, and the positioning pressure ring 234 presses the wheel hub tightly and fixes it. Then, according to the welding requirements of the wheel hub, the knob 2376 is turned to adjust the horizontal position of the welding gun 2379, while the threaded collar 2372 is rotated. Adjust the height of the welding gun 2379 so that it is aligned with the welding area of ​​the wheel hub. Then, start the welding equipment and begin welding the left wheel hub. While welding the left wheel hub, the next wheel hub to be welded can be placed on the positioning bracket 24 of the right welding station 2 and the same positioning and fixing operation can be performed to prepare for the next welding. After the left wheel hub is welded, the cylinder 232 drives the sliding frame 233 to rise, release the positioning pressure ring 234, and remove the welded wheel hub. At the same time, the right welding station 2 is ready to start welding immediately. This cycle is repeated to achieve alternating operation of the two stations and improve welding efficiency.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
