Self-adaptive surface treatment device and rolling method

Abstract

The invention discloses a self-adaptive surface treatment device and rolling method. The device comprises a rolling head body and a rolling head secondary disk, first piston chambers are formed in the rolling head body, an eccentric piston block is installed in each first piston chamber, the part, outside the first piston chambers, of the rolling head body is provided with first oil ducts, second oil ducts are formed in the part, outside the first oil ducts, of the surface of the rolling head body, and the second oil ducts are arranged to be in a T shape; seal rings are arranged between the rolling head body and the rolling head secondary disk, and the seal rings isolate the second oil ducts to form six independent sealed annular sections; multiple second piston chambers are formed in the rolling head secondary disk, a cylindrical piston is arranged in each second piston chamber, and five second piston chambers are formed in the position corresponding to each second oil duct; an alloy column pin is arranged on the lower half portion of each second piston chamber. In the self-adaptive surface treatment device, the alloy column pins have a certain floating function and certain flexibility, so that the device is applicable to surface treatment of a work piece which is provided with a certain radian.

Description

technical field [0001] This scheme is mainly used in the surface flexible treatment technology in the technical field of high-precision equipment, specifically an adaptive surface treatment device. Background technique [0002] The damage of metal materials often starts from the surface. For example, parts such as crankshafts of internal combustion engines, axles of trains, leaf springs of automobiles, and engine blades are continuously subjected to cyclic loads during work. Over time, fatigue cracks often occur on the working surfaces of parts. Cracks grow gradually, eventually leading to fatigue failure of the part. Fatigue damage is one of the main reasons for the failure of mechanical parts. According to statistics, more than 80% of the failures of mechanical parts are due to fatigue damage, and there is no obvious deformation before damage. Therefore, fatigue damage often causes major accidents. [0003] Many countries are vigorously researching, developing and applyin...

Problems solved by technology

[0005] Taking the automobile leaf spring as an example, the automobile leaf spring has a certain radian, and ordinary rolling tools cannot perform effective and uniform treatment. The reason is that the rolling and leaf spring are in rigid contact, which is easy to cause scratches
