Abstract
The invention provides a machining technology for a cam shaft of an automobile engine. The machining technology is characterized by comprising the following steps that firstly, a blank with the top quality is selected and checked, and whether flaws exist or not is checked; secondly, a face miller is used for drilling the center position of the blank, an oil hole is drilled, and burrs are removed; thirdly, all shaft diameters and circular beads are roughly ground; fourthly, a root groove is cleaned and burrs are removed; fifthly, a shaft rod is straightened; sixthly, all main shaft diameters, small shaft diameters, the circular beads and the front end face of the first main shaft diameter are precisely ground; seventhly, burrs are removed after all cams are roughly and precisely ground; eighthly, flaw detection is conducted; ninthly, polishing is conducted; tenthly, cleaning is conducted; and eleventhly, antirust liquid is smeared after quality inspection. By means of the manner, wear resistance, lubricity, strength and supporting force of the cam shaft of the automobile engine can be improved.
Description
Technical field
The present invention relates to auto parts and components field, particularly relate to a kind of camshaft of car engine processing technology.
Background technology
Camshaft is parts in piston engine.Its effect is the opening and closing action controlling valve.Although the rotating speed of camshaft is the half (identical with bent axle at the rotating speed of two stroke engine convexity wheel shaft) of bent axle in four-stroke engine, but its rotating speed is still very high usually, and need to bear very large moment of torsion, therefore very high to the requirement of camshaft in intensity and support in design.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of camshaft of car engine processing technology, can improve the wearability of camshaft of car engine, lubricity and intensity and support force.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of camshaft of car engine processing technology, it is characterized in that, comprises the steps: that (1) selects the blank of top quality to check whether there is flaw; (2) hole in blank center with face miller, bore oilhole, remove burr; (3) roughly grind whole diameter of axle, shoulder; (4) clear up root groove and remove burr; (5) alignment axostylus axostyle; (6) each main shaft diameter, small axle diameter, shoulder and the first main shaft diameter front end face is refined; (7) burr is removed after the whole cam of thick fine grinding; (8) detect a flaw; (9) polishing; (10) clean; (11) antirust solution is coated with after carrying out quality inspection.
In a preferred embodiment of the present invention, in described step (5), alignment axostylus axostyle be manual straightener.
In a preferred embodiment of the present invention, in described step (8), defectoscope be magnetic powder flaw detector.
The invention has the beneficial effects as follows: the present invention can improve the wearability of camshaft of car engine, lubricity and intensity and support force.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
A kind of camshaft of car engine processing technology, is characterized in that, comprises the steps: that (1) selects the blank of top quality to check whether there is flaw; (2) hole in blank center with face miller, bore oilhole, remove burr; (3) roughly grind whole diameter of axle, shoulder; (4) clear up root groove and remove burr; (5) alignment axostylus axostyle; (6) each main shaft diameter, small axle diameter, shoulder and the first main shaft diameter front end face is refined; (7) burr is removed after the whole cam of thick fine grinding; (8) detect a flaw; (9) polishing; (10) clean; (11) antirust solution is coated with after carrying out quality inspection.
Further illustrate, in described step (5), alignment axostylus axostyle be manual straightener.
Further illustrate again, in described step (8), defectoscope be magnetic powder flaw detector.
Be different from prior art.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
