The Virtual Design of the Device of the Welded Orientation Piece for Double Piston Ring

The double piston ring inserted in the air cylinder of the engine is a new energy-saving device which can improve the efficiency of the engine.It is simple in design and reliable in structure.The orientation piece welded on the piston ring is an important process to guarantee this technology while the design of this welding device is the key to the realization of the energy-saving goal.While designing this welding device,computer is used as an assistance,which successfully completes the following works: the structural design of the welding device,assembling,interference checking and motion simulating as well as the transfer from three-dimensional model to two-dimensional engineering drawing.The design is direct-viewing,figurative,exact and reliable,which has both improved the design efficiency and lowered the production cost.
