It realizes structure of subassembly connection to take shape through friction liquid column

The utility model discloses an it realizes subassembly connection structure and method to take shape through the friction liquid column, treat coupling assembling including at least two, treat coupling assembling in proper order the overlap joint form the sub -assembly that has the interface, characterized by: has predetermine the excellent hole of stopper on the sub -assembly, has filled in excellent hole and for through the blind hole of all interfaces, fill in the diameter that excellent hole diameter slightly is greater than welding stopper stick, during the front end of welding stopper stick can insert the excellent hole of stopper, with the hole bottom contact in stopper excellent hole and with pore wall clearance fit, plastic deformation takes place through rotatory hole bottom friction heat production with stopper excellent hole for welding stopper stick for the clearance between welding stopper stick and the excellent hole of stopper pore wall is filled to the plasticity thing, and plasticity thing c
