Technical Field

[0001] This utility model relates to the field of flywheel processing technology, specifically to a welding device for automotive flywheel gear rings. Background Technology

[0002] The flywheel, this seemingly simple disc-shaped component, is an indispensable "energy bank" and operating stabilizer in a car engine. The flywheel is the engine's power "buffer" and transmission hub, and its condition directly affects the vehicle's smoothness, power, and lifespan.

[0003] In the existing technology, during the flywheel manufacturing process, the gear ring needs to be assembled onto the outside of the flywheel. After assembly, the flywheel and gear ring are welded and fixed together using a welding device. However, the existing automotive flywheel gear ring welding device requires manual rotation of the flywheel and gear ring after welding one side of the flywheel and gear ring, and then welding the other end of the flywheel and gear ring. This operation is cumbersome and time-consuming, which is not conducive to the production and use of automotive flywheel gear rings. Utility Model Content

The laser welding assembly is fixedly connected to the lower surface of the mounting plate.

[0010] Furthermore, a positioning plate is fixedly connected to the lower surface of the mounting plate, and a spray pipe is vertically arranged at the other end of the positioning plate, with a spray head at the bottom end of the spray pipe.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an automotive flywheel gear ring welding device, including a base 1, a receiving box 2 fixedly connected to one end of the top of the base 1, a rotating shaft 5 rotatably arranged on the upper part of the other side of the receiving box 2, and a C-shaped frame 7 fixedly connected to the other end of the rotating shaft 5.

[0019] The top and bottom of the C-shaped frame 7 are fixedly connected to a first electric telescopic rod 8. The inner end of the first electric telescopic rod 8 is fixedly connected to a lifting plate 9. The inner side of the lifting plate 9 is rotatably provided with a bearing plate 12.

[0020] An L-shaped plate 14 is fixedly connected to the other end of the top of the base 1, and a laser welding assembly 17 that moves vertically is provided on one side of the L-shaped plate 14.

[0021] After the flywheel with the gear ring is placed on the upper surface of the lower support plate 12, the flywheel can be positioned by the lower positioning protrusion 13. Then, after the first electric telescopic rod 8 is extended, it can drive the two support plates 12 to move closer to each other. After the two support plates 12 come into contact with the surface of the flywheel, the flywheel can be clamped and fixed.

[0022] After the bearing plate 12 rotates, it can drive the flywheel and the gear ring to rotate. The welding end of the laser welding component 17 is located at the splice of the flywheel and the gear ring. After the laser welding component 17 is working, welding processing can be performed between the flywheel and the gear ring.

[0023] After processing, the flywheel and gear ring, which are welded on one side, can be rotated by rotating shaft 5, which facilitates continuous welding operations, reduces the workload of workers, and improves the welding efficiency of flywheel and gear ring.

[0024] The inner cavity of the container 2 is fixedly connected to a first motor 3, one end of the rotating shaft 5 extends into the inner cavity of the container 2, the output shaft of the first motor 3 is fixedly connected to a first bevel gear 4, and the surface of the rotating shaft 5 is fixedly connected to a second bevel gear 6 that meshes with the first bevel gear 4.

[0025] After the first motor 3 drives the first bevel gear 4 to rotate, it can drive the rotating shaft 5 to rotate through the transmission of the second bevel gear 6, thereby driving the C-shaped frame 7 to flip.

[0026] A second motor 10 is fixedly connected to the outer side of the lifting plate 9. The output shaft of the second motor 10 extends to the inner side of the lifting plate 9 and is fixedly connected to a rotating rod 11. The inner end of the rotating rod 11 is fixedly connected to the outer side of the bearing plate 12.

[0027] After the second motor 10 starts working, it can drive the bearing plate 12 to rotate through the connection of the rotating rod 11, which in turn drives the flywheel and the gear ring to rotate, making it convenient to carry out continuous welding work at the splice.

[0033] The water collection tank 21 facilitates the collection of water generated during cooling. After opening the valve 23, the water can be discharged through the drain pipe 22.

[0034] During operation, the flywheel with the gear ring is placed on the upper surface of the lower support plate 12. The flywheel is then positioned by the lower positioning protrusion 13. After the first electric telescopic rod 8 extends, it can drive the two support plates 12 to move closer to each other. The flywheel is clamped and fixed after the two support plates 12 come into contact with the surface of the flywheel. The rotation of the support plate 12 can drive the flywheel and gear ring to rotate. The welding end of the laser welding component 17 is located at the splice of the flywheel and gear ring. After the laser welding component 17 is working, welding processing can be performed between the flywheel and gear ring. After the processing is completed, the flywheel and gear ring can be flipped by rotating the rotating shaft 5, which facilitates continuous welding processing operation.
