The invention discloses an efficient
processing line for automobile pistons, including a first turning and drilling compound
machine tool, a second turning and drilling compound
machine tool, a compound boring
machine and a compound lathe arranged in an arrangement. The first turning and drilling compound
machine tool is used for
processing the pin seat oil return hole, the ring segment straight oil hole, the rough and fine stopper, the rough turning of the first three ring grooves, and the rough turning of the outer circle skirt process of the
piston. The second turning and drilling compound
machine tool is used for the
piston ring segment oblique oil hole or the ring segment straight oil hole, the rough and fine
combustion chamber process, the compound boring machine is used for
processing the rough boring hole, the snap ring groove, the inner and outer chamfers, and the fine boring process of the pin holes on both sides of the
piston, and the compound lathe is used for processing the piston special-shaped outer circle and the fine turning of the first three ring grooves. The invention integrates more than a dozen processes on the
production line formed by four devices, reduces equipment occupancy, reduces operators, reduces the time consumed by processing multiple clamping, coordinates the processing time between each process, saves time, reduces labor intensity, and improves production efficiency.
