[0020] This utility model provides a welding equipment for electric vehicle wheel hub spokes, including a cabinet with several processing stations. Each processing station includes a rotating bearing mechanism 2, a welding mechanism 1, and a welding wire feeding mechanism 3. The welding mechanism 1 includes a support 10 mounted on the top of the cabinet, an X-axis linear drive device 11 mounted on the top of the support 10, a Y-axis linear drive device 12 connected to the X-axis linear drive device 11, a Z-axis linear drive device 13 connected to the Y-axis linear drive device 12, and a laser welding head 14 connected to the Z-axis linear drive device 13. The support 10 includes a platform 100. The rotating bearing mechanism 2 includes a bearing... The lifting mechanism 20 and the rotating mechanism 24 are included. The lifting mechanism 20 includes a lifting drive mechanism 21, a lifting seat 22 driven by the lifting drive mechanism 21, and a lower loading mold 23 rotatably connected to the lifting seat 22. The rotating mechanism 24 includes an annular slewing bearing 240 rotatably connected to the bottom of the platform 100, an annular upper mold 241 fixedly connected to the bottom of the annular slewing bearing 240, a connecting rod 242 connecting the lower loading mold 23 and the annular slewing bearing 240, and a rotating drive mechanism 25 for driving the annular slewing bearing 240 to rotate. The platform 100 has a processing window 101 that communicates with the inside of the annular slewing bearing 240.

[0021] Its working principle is as follows: First, the outer ring of the wheel hub is placed on the lower mold 23, and then the spokes of the wheel hub are placed inside the outer ring of the wheel hub. The lifting mechanism 21 drives the lifting seat 22 to rise, thereby driving the outer ring and spokes to rise synchronously, so as to position the outer ring and spokes between the annular upper mold 241 and the lower mold 23. When the X-axis linear drive device 11, Y-axis linear drive device 12, and Z-axis linear drive device 13 are working, they can drive the laser welding head 14 to move in the X-axis, Y-axis, and Z-axis directions respectively. The welding wire feeding mechanism 3 can supply welding wire to the laser welding head 14. The laser welding head 14 performs welding operations on the splice of the spokes and the outer ring through the processing window 101. During the welding process, the rotary drive mechanism 25 drives the annular slewing bearing 240 to rotate. The rotating annular upper mold 241 and the material-carrying lower mold 23 will drive the outer ring and spokes to rotate, thereby performing complete welding on the product. After the welding is completed, the lifting drive mechanism 21 drives the material-carrying lower mold 23 to reset, and the product can be taken out from the material-carrying lower mold 23. This can realize the automation of workpiece positioning, rotation and welding, effectively saving manpower, reducing production costs and improving production efficiency.

[0022] Based on the above embodiments, the lifting seat 22 includes a top plate 220, a bottom frame 221, and a first guide rod 222 connecting the four sides of the top plate 220 and the bottom frame 221. A first guide sleeve 223 matching the first guide rod 222 is provided through the top of the cabinet, and the first guide rod 222 is movably disposed on the first guide sleeve 223. The lifting drive mechanism 21 includes a lifting cylinder 210 disposed on the top wall of the cabinet, a T-joint 211 connected to the output shaft of the lifting cylinder 210, and a connecting plate 212 connected to the bottom of the top plate 220. A T-slot 212a matching the T-joint 211 is provided on the connecting plate 212, and the T-joint 211 is movably disposed on the T-slot 212a. When the lifting cylinder 210 is working, the T-joint 211 drives the connecting plate 212 to rise and fall, and the first guide rod 222 will move along the first guide sleeve 223, thereby driving the lower die 23 to move up and down. When the annular slewing bearing 240 is driven to rotate by the rotary drive mechanism 25, the lower die 23 and the lifting seat 22 rotate synchronously with the annular slewing bearing 240, and the T-joint 211 will rotate on the T-groove 212a, which can drive the outer ring of the hub and the spokes to rotate.

[0023] Based on the above embodiments, the loading lower mold 23 includes a turntable 230, a connecting shaft 231 connected to the bottom of the turntable 230, and a limiting lower mold 232 connected to the top of the turntable 230. A bushing 233 is fixedly connected to the top of the top plate 220. The connecting shaft 231 and the bushing 233 are connected by a bearing. An ear plate 234 is fixedly connected to the bottom of the turntable 230. The bottom end of the connecting rod 242 is fixedly connected to one end of the ear plate 234. The outer edge of the limiting lower mold 232 matches the inner edge of the outer ring of the wheel hub. The top of the limiting lower mold 232 can support the spokes of the wheel hub, and can realize the synchronous rotation of the annular slewing bearing 240 and the turntable 230.

[0024] Based on the above embodiments, the turntable 230 is evenly distributed with elastic leveling components 26. The elastic leveling components 26 include a fixed plate 260 fixedly connected to the bottom of the turntable 230, a support plate 261, a plurality of second guide rods 262 fixedly connected to the bottom of the support plate 261, and a second guide sleeve 263 that is disposed through the fixed plate 260 and corresponds to the second guide rods 262. The second guide rods 262 are movably disposed on the second guide sleeve 263. The turntable 230 is provided with a receiving groove 230a that corresponds to the support plate 261. The support plate 261 is movably disposed in the receiving groove 230a. A buffer spring 264 is sleeved on the second guide rods 262 and abuts against the support plate 261 and the fixed plate 260. The outer ring of the wheel hub is placed between the top of the support plates 261 of several elastic leveling components 26. The turntable 230 is raised by the lifting cylinder 210 so that the outer ring and spokes are stuck between the annular upper mold 241 and the limiting lower mold 232. The buffer spring 264 will be compressed and the support plate 261 will retract into the receiving groove 230a. Each elastic leveling component 26 plays an elastic buffering role at different positions of the outer ring, which can level the outer ring, prevent the outer ring from tilting, and improve the product processing quality.

The circumference of the annular slewing bearing 240 is provided with a toothed surface 240a that meshes with the gear 251. When the servo motor 252 is working, it will drive the gear 251 to rotate, and the rotating gear 251 will drive the annular slewing bearing 240 to rotate, thereby performing rotary processing on the workpiece on the lower die 23.

[0026] Based on the above embodiments, the X-axis linear drive device 11, the Y-axis linear drive device 12, and the Z-axis linear drive device 13 are all lead screw slides, which have good working stability and are easy to install.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
