VVTI VVT-i is the abbreviation of Variable Valve Timing-intelligent, and the implication of its representative is exactly an intelligence variable valve control system in correct time.This device has improved intake efficiency, has realized abundant output low, medium speed scope internal torque, has guaranteed can both obtain under each operating mode enough power performances.Another advanced part is the lightweight that all aluminium alloy cylinder body brings, and has not only reduced quality, has also reduced the noise of engine.The main purpose of variable valve timing variable valve timing controlling organization is to keep under the engine idling performance situation, improves the full load performance.This mechanism keeps the lasting angle of IO Intake Valve Opens constant, changes the inlet valve switching and increases aeration quantity constantly.
Under existing technology, this type of part, especially the conventional processing method of automobile engine VVT system cover board machine is generally: receiving inspection-blanking-thick boring-Che A face and boring inner chamber-brill mill the back side-brill and mill die cavity-brill and mill big plane-anodic oxidation-check shipment; But the method manufacturing procedure in practical operation is numerous and diverse, and the intermediate steps that easy appearance causes because of carelessness is made mistakes or lacked, and has seriously influenced the quality of output product like this, and has adopted this type processing method consumed time longer.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can guarantee that the cover plate machined of automobile engine VVT system is stable, optimize operation, guarantee the processing method of the automobile engine VVT system cover board machine of crudy.
The present invention adopts following technical scheme for solving the problems of the technologies described above: the processing method of a kind of automobile engine VVT system cover board machine comprises the steps:
Step 1: receiving inspection;
Step 2: through the blanking machine blanking;
Step 3: forging molding on hot forging equipment, guarantee the compactness of materials and parts, remove too much surplus;
Step 4: the materials and parts after will forging carry out T6 to be handled;
Step 5: the big plane of processing car on the CNC lathe is the following process positioning reference;
Step 6: processing car facet and thick boring on the CNC lathe are the following process positioning reference;
Step 7: big plane, groove milling and boring are milled in processing on the CNC machining center, through foundry goods appearance profile location, bottom surface, die mould chamber;
Step 8: back side flange face is milled in processing on the CNC machining center, through big planar end location, uses pin-and-hole spacing;
Step 9: inner chamber and screw thread are milled in processing on the CNC machining center, support, press end face and screw thread M27 through location, hole, back side profile;
