It solves the problem that the existing toothed rings are mainly installed on their surface by manual welding, which can easily cause the reinforcement ring to tilt. At the same time, the reinforcement ring, which needs to be continuously rotated for welding, cannot effectively rotate and move synchronously with the toothed ring, resulting in welding misalignment.

The laser welder 9 can emit laser and heat and weld the toothed ring workpiece 4 and the reinforcing ring 5.

[0028] As a technical optimization of this utility model, the laser welder 9 is extended to the bottom of the toothed ring workpiece 4 by the extension plate 8, and the laser beam can directly act on the joint surface of the toothed ring and the reinforcing ring 5 to ensure the penetration depth and welding strength.

[0029] refer to Figure 2 The extension plate 8 is designed to be hollow, and both sides of the laser welder 9 are fixedly connected to sliders 10 located inside the extension plate 8, and the sliders 10 are slidably connected to the extension plate 8.

[0030] As a technical optimization of this utility model, the hollow extension plate 8 reduces weight and provides sliding space, and the slider 10 allows the laser welder 9 to move radially along the toothed ring to adapt to the welding needs of workpieces of different sizes.

[0031] refer to Figure 6 The positioning structure 6 includes a connecting block 11 fixedly connected to the surface of the sleeve 2. A pressure plate 12 is movably connected to the inner side of the connecting block 11 via a pin. The side of the pressure plate 12 away from the connecting block 11 extends to the outer side of the reinforcing ring 5. The pressure plate 12 can swing around the pin inside the connecting block 11 as the axis and control the extrusion pressure.

[0032] As a technical optimization of this utility model, the pressure plate 12 swings with the pin as the fulcrum, automatically adapting to the slight deformation or installation error of the reinforcing ring 5, and providing dynamic balanced pressure.

[0033] refer to Figure 6 An electric telescopic rod 13 is fixedly connected to the bottom of the support 1. The output end of the electric telescopic rod 13 passes through the sleeve 2 and extends to the top of the sleeve 2. A conical sleeve 14 is fixedly connected to the output end of the electric telescopic rod 13. The outer surface of the conical sleeve 14 is in contact with the surface of the pressure plate 12.

[0034] As a technical optimization of this utility model, the conical sleeve 14 is driven to rise and fall by the electric telescopic rod 13, so as to realize the automatic opening and closing of the pressure plate 12 without manual intervention. Moreover, the inclined surface of the conical sleeve 14 converts the vertical thrust into the horizontal clamping force of the pressure plate 12, so as to achieve high pressure clamping with a small driving force.

The outer surface of the transmission roller 17 contacts the outer edge of the tapered sleeve 14.

[0038] As a technical optimization of this utility model, the sliding friction between the conical sleeve 14 and the pressure plate 12 is converted into rolling friction by the transmission roller 17, which improves the transmission efficiency and extends the service life of the components. At the same time, the movable block 16 and the pin structure ensure that the movement of the conical sleeve 14 is accurately converted into the radial displacement of the pressure plate 12, avoiding jamming.

[0040] As a technical optimization of this utility model, the power is transmitted through the driving wheel 19 and the driven wheel 20 to ensure that the sleeve 2 drives the workpiece to rotate evenly.

[0041] The working principle and usage process of this utility model are as follows: The toothed ring workpiece 4 is placed on the bearing ring 3, and the reinforcing ring 5 is fitted onto the outside of the toothed ring workpiece 4. The bearing ring 3 is movably connected to the support 1 through the sleeve 2, ensuring that the workpiece can rotate freely. When the reinforcing ring 5 is in place, the electric telescopic rod 13 pushes the conical sleeve 14 downwards. The inclined surface of the conical sleeve 14 contacts the transmission roller 17 on the outside of the pressure plate 12, pushing the pressure plate 12 to swing inwards around the pin of the connecting block 11. When the inner side of the pressure plate 12 contacts the reinforcing ring 5, the reinforcing ring 5 is squeezed and fixed. The drive motor 18 drives the drive wheel 19 to rotate, which meshes with the driven wheel 20 fixed to the sleeve 2, driving the bearing ring 3, the toothed ring workpiece 4 and the reinforcing ring 5 to rotate synchronously. The laser welder 9 extends to the bottom of the toothed ring through the extension plate 8. After starting, the laser welder 9 emits a laser beam to continuously irradiate the joint surface of the toothed ring and the reinforcing ring 5, achieving uniform welding in the circumferential direction during synchronous rotation and avoiding deviation. After welding is completed, the electric telescopic rod 13 extends and pushes the conical sleeve 14 to rise. The pressure plate 12 automatically resets under the elastic force of the spring plate 15, releasing the pressure on the reinforcing ring 5.

[0042] In summary, this bimetallic composite cast toothed ring base reinforcement device applies uniform pressure to the reinforcement ring 5 through the positioning structure 6, ensuring that the reinforcement ring 5 is always perpendicularly attached to the toothed ring workpiece 4, eliminating the tilting problem caused by manual welding. At the same time, the sleeve 2 drives the bearing ring 3, the toothed ring workpiece 4, and the reinforcement ring 5 to rotate as a whole. During welding, the workpiece and the reinforcement ring 5 move synchronously, avoiding welding offset caused by relative displacement.
