The lifting drive 21 is installed on the bracket body 1. A steering drive 26 is installed at the telescopic end of the lifting drive 21. The steering drive 26 is used to drive the bridging frame 22 to rotate. The telescopic drive 23 is installed on the bridging frame 22. The telescopic drive 23 is used to drive the clamping drive 24 to slide on the bridging frame 22. A clamping block 25 is provided on the clamping drive 24.

[0032] Through the above design scheme, when automatic welding work is required, the steering drive 26 controls the bridge frame 22 to turn towards the direction of the feeding assembly 6, the telescopic drive 23 controls the clamping drive 24 to come to the top of the grinding disc to be welded, and then the lifting drive 21 drives the bridge frame 22 to descend so that the clamping block 25 probes into the hole in the center of the grinding disc, the clamping drive 24 controls the clamping block 25 to expand outward so that the clamping block 25 clamps the grinding disc, and the lifting drive 21 drives the bridge frame 22 to lift the grinding disc together to avoid the steering drive 26 being accidentally touched when driving the grinding disc to rotate; the steering drive 26 and the telescopic drive 23 assist each other to place the grinding disc to be welded into the welding assembly, and after the welding is completed, the clamping assembly 2 clamps the grinding disc and places it in the discharging assembly 7, and then the steering drive 26 drives the bridge frame 22 back to the top of the feeding assembly 6 again to repeat the loading work. In this embodiment, the clamping block 25 is detachably connected to the clamping drive member 24. When facing grinding discs of different specifications, the appropriate clamping block 25 can be replaced according to needs, and the clamping block 25 is made of high-temperature resistant material.

[0033] In this embodiment, the welding assembly includes a high-frequency induction welder 3, a clamping portion 5 and a receiving platform 4. The high-frequency induction welder 3 is installed on the bracket body 1, the receiving platform 4 is arranged directly below the high-frequency induction welder 3, and the clamping portion 5 is arranged directly above the high-frequency induction welder 3; the axis of the clamping portion 5 and the receiving platform 4 coincides with the axis of the induction coil of the high-frequency induction welder 3; the high-frequency induction welder 3 is installed on the bracket body 1, the receiving platform 4 is used to place the grinding disc to be welded and perform welding, and the clamping portion 5 is used to press the grinding disc on the receiving platform 4.

[0034] In this embodiment, the receiving platform 4 includes a fixed seat 41, a rotating drum 42 and a lifting seat 43. The fixed seat 41 is installed on the bracket body 1, and the rotating drum 42 is installed in the fixed seat 41 through a bearing. The lifting seat 43 can slide in the rotating drum 42, and a lifting elastic member 44 is arranged in the rotating drum 42. One end of the lifting elastic member 44 rests on the lifting seat 43, and the other end rests in the rotating drum 42; a detachable pad 45 is arranged on the lifting seat 43.

[0035] In this embodiment, the clamping part 5 includes a lifting frame 52, a lifting drive 51 and a clamping drive 53. The lifting drive 51 is installed on the bracket body 1.

Under the action of the lifting elastic member 44, the grinding disc can be clamped, and it can also avoid the grinding disc being damaged by clamping too tightly. When performing induction heating welding, the rotating drum 42 can be equipped with a motor at its bottom to drive the grinding disc to rotate according to needs. Under the action of the bearing, the pressure plate 54 can also rotate with the grinding disc. Under the action of centrifugal force, the grinding disc can be welded more evenly to improve the welding accuracy of the grinding disc. After welding is completed, the lifting drive 51 controls the lifting frame 52 to rise. During the rising process, the pressing drive 53 will also be retracted synchronously to keep the pressure plate 54 away from the grinding disc; the lifting seat 43 will rise after losing the restriction under the action of the lifting elastic member 44, so that the clamping drive 24 can clamp the grinding disc.

[0037] The pad 45 is used to limit the relative position of the grinding disc so that the grinding disc can be fixed on the lifting seat 43. In the present embodiment, the pad 45 and the pressure plate 54 are both made of high temperature resistant materials to avoid damage to other components when the temperature of the welded grinding disc is too high. In the present embodiment, the pressure plate 54 and the pad 45 can be replaced as needed to adapt to grinding discs of different specifications.
