[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a leveling device for welding rings according to the present invention includes a clamping ring sleeved on a pipe 1. The clamping ring is divided into two halves in the middle, consisting of two first half-rings 2. One end of each first half-ring 2 is provided with an arc-shaped groove, which is combined to form an annular groove. Two second half-rings 3 are provided in the annular groove, which is combined to form a driving ring. One end of the driving ring extends to the outside along the opening of the annular groove and is equipped with multiple protruding teeth 11 in an annular structure. A gear 8 that meshes with the protruding teeth 11 is provided on the outside of the driving ring. Multiple fixing rods are installed on the end face of the driving ring, and a grinding mechanism is installed on the other end of each fixing rod.

[0023] In this embodiment, the grinding mechanism includes a fixing block 6 and a grinding block 7. The fixing block 6 is mounted on a fixing rod and has multiple first screw holes. A metal block is embedded in one end of the grinding block 7 facing the fixing block 6. A second screw hole communicating with the first screw holes is provided on the metal block. First bolts are threaded into the corresponding first screw holes and second screw holes. A grinding groove is provided at the end of the grinding block 7 away from the pipe 1. The grinding groove is in contact with the surface of the welding ring between the pipe 1. The grinding block is made of tungsten steel with grinding patterns to ensure its strength.

[0024] In this embodiment, both ends of the first half-ring 2 protrude to form fixing parts 5, and adjacent fixing parts 5 are fitted together. Each fixing part 5 is provided with a fixing hole, and a second bolt is inserted into each of the opposite fixing holes. One end of each second bolt is threaded with a nut to lock the fixing part 5.

[0025] In this embodiment, a motor 10 is installed on one side of a semi-ring, and the shaft of the motor 10 is fixedly connected to the gear 8; wherein, the motor is connected to a power supply and a controller through wires, and the controller can control the start and stop of the motor.

[0026] In this embodiment, the outer side of the semi-ring is provided with an arc-shaped baffle 4 that covers the protruding tooth 11. The arc-shaped baffle 4 on one side arches up to cover the outer ring of the gear 8 and covers the cover 9. One end of the arc-shaped baffle 4 is bent and installed on the semi-ring.

[0027] The cover and curved baffle can cover the protruding teeth and gears, avoiding direct contact and injury, thus increasing safety.

[0028] In this embodiment, each of the inner walls of the arc-shaped grooves is provided with a positioning groove, and the positioning grooves are combined to form a positioning ring.
