Zusammenfassung: | The utility model discloses a welding assembly, which belongs to the technical field of welding equipment and comprises a chuck and a main shaft which are connected with each other, a positioning sleeve is arranged at the joint of the chuck and the main shaft, and a plurality of first calibration holes and second calibration holes are formed in the positioning sleeve around the axis of the positioning sleeve. The axes of the first calibration hole and the second calibration hole face the chuck and the main shaft respectively, bolts are arranged in the first calibration hole and the second calibration hole respectively, and the first calibration hole and the second calibration hole are both in threaded fit with the bolts. When the diameter jump out-of-tolerance of the chuck exists, the calibration of the diameter jump out-of-tolerance of the chuck can be rapidly completed only by screwing the bolt on one side of the diameter jump point of the chuck inwards step by step, the bolt can belocked after the calibrat |
