Under the action of pressure, relative movement between welding contact end surfaces is utilized to generate friction heat and plastic deformation heat at a friction surface and a nearby area thereof under the action of constant or increasing pressure and torque, so that the temperature of the nearby area thereof is increased to a temperature range close to but generally lower than a melting point, the deformation resistance of the material is reduced, the plasticity is improved, an oxide film of an interface is broken, plastic deformation and flow are generated along with the material under the action of top forging pressure, and the solid welding method for welding is realized through molecular diffusion and recrystallization of the interface. Friction welding is a welding technology with high welding efficiency and good welding quality, and when friction welding is carried out, a workpiece is clamped by a chuck at first, so that the workpiece is ensured not to shake during friction welding, and the welding precision is improved.

Through the prior art, hydraulic oil enters the cylinder body of each small oil cylinder through oil cylinder base oil distribution, so that the piston of each small oil cylinder is ejected upwards, the tension of a chuck disc spring mechanism is overcome to push the release disc of the chuck and drive the inclined wedge to move rightwards, and the sliding seat and the clamping jaw are released through the chute on the inclined wedge. When oil distribution is stopped, the restoring force generated by the chuck disc spring mechanism pushes the release disc and drives the inclined wedge block to move leftwards, and then the slide seat and the clamping jaw generate clamping movement through the chute on the inclined wedge block.
