A kind of plug repair welding main shaft, comprise main shaft housing, central shaft, main shaft coolant jacket, pressure sensor, yielding coupling and servo water-cooled machine, described main shaft coolant jacket is fixedly connected in main shaft housing, and main shaft coolant jacket and main shaft housing form circulating water groove, described central shaft is inner through main shaft coolant jacket, described central shaft two ends are supported by angular contact ball bearing and cylinder roller bearing respectively, described central shaft one end is provided with stirring-head, and the central shaft other end to be connected with servomotor by yielding coupling and to transmit power, between described main shaft housing and main shaft coolant jacket, pressure sensor is housed, in order to detect the top section pressure of plug repair welding main shaft.
As the further scheme of the present invention: described central shaft front end coordinates with angular contact ball bearing group inner ring, described main shaft coolant jacket coordinates with angular contact ball bearing group inner ring, described locking nut one lock corner contact ball bearing group inner ring, and be provided with labyrinth sealing between locking nut one and angular contact ball bearing group.
As the further scheme of the present invention: described central shaft rear end coordinates with cylinder roller bearing inner ring, described main shaft coolant jacket coordinates with cylinder roller bearing inner ring, described locking nut two locks cylinder roller bearing inner ring, and is provided with labyrinth sealing between locking nut two and cylinder roller bearing.
As the further scheme of the present invention: described main shaft coolant jacket is provided with water circulation cooling bath, and the two ends of cooling bath are provided with O type circle seal groove.
As the further scheme of the present invention: described main shaft housing has water inlet and delivery port.
As the further scheme of the present invention: described cooling water enters in cooling bath from the water inlet main shaft housing, current from bottom to top, flow out from delivery port, thus the bearing that cooling is easily generated heat because of High Rotation Speed.
As the further scheme of the present invention: described servomotor maximum speed can reach 8000rpm, and the servomotor type of cooling is water-cooled.
Compared with prior art, the invention has the beneficial effects as follows: the burn because soldering turret electrode splashes or shunting produces or scald situation can be reduced, the quality be conducive to improving operating personnel's security, promoting solder joint.Repair welding joint quality of the present invention is high, residual stress is low, welding deformation is little, and strength of joint improves a lot than conventional arc repair welding joint, simple to operation, compact conformation and bonding speed is fast, can be used for the repair welding of weld defect at the bottom of space shuttle external tank case.
