Abstract
The invention discloses a machining process for a turbo head of a rotor shaft of a turbocharger. The machining process comprises the following steps: 1, roughly machining the welded and thermally treated rotor shaft of the turbocharger, and reserving a corresponding margin according to the production specification; 2, putting the roughly machined rotor shaft onto a high-precision lathe, machining the central hole in the turbo head of the rotor shaft to enable the depth of the central hole in the turbo head of the rotor shaft to be more than or equal to 3mm, and rounding a large-diameter part of the rotor shaft after the central hole is completely machined; 3, balancing a single piece according to a dynamic balance standard, wherein the rotor shaft of the turbocharger is required to meet the dynamic balance standard; 4, installing a tool which is required to be a 60-degree knife on the high-precision lathe, searching for a corresponding feeler gauge according to the balance amount of the single piece, and performing duplicate removal on the feeler gauge and the rotor shaft of the turbocharger to enable the angle of the feeler gauge to be 180 degrees correspondingly. According to the machining process, a hole in the turbo head of the rotor shaft is changed, so that the weight is reduced, and the working efficiency is greatly improved; meanwhile, the service life of the rotor shaft is prolonged.
Description
Technical field
The present invention relates to a kind of turbocharger rotor arbor wheel head processing technology.
Background technology
Existing turbocharger rotor axle is heavier because of weight, causes the operating efficiency of turbocharger rotor axle lower, has not only wasted a lot of resources, increase manufacturing cost, and outward appearance ugliness, service life is shorter, cannot mention in the same breath with external product at all.
Summary of the invention
Object of the present invention is exactly defect and the deficiency existing for overcoming above-mentioned prior art, and a kind of turbocharger rotor arbor wheel head processing technology is provided.
The technical scheme adopting is:
Turbocharger rotor arbor wheel head processing technology, is characterized in that comprising following technical process:
1, first carrying out roughing through welding and heat treated supercharger rotor axle, leave corresponding surplus by its product specification.
2, the armature spindle after roughing is placed on lathe with high precision, centre bore to rotor arbor wheel head position is processed, make rotor arbor wheel head depth of center hole be not less than 3mm dark (so that changing eye), process after centre bore, by the large-diameter portion position rounding of armature spindle.
The dynamic balance level that 3, will reach according to turbocharger rotor axle is carried out single-piece balance.
4, mounting cutter on fine turning lathe, this cutter is necessary for 60 ° of cone cuttves, its cutter fixes to clamp on the little supporting plate of fine turning lathe, will be wherein supporting plate to remove gyration be 60, find corresponding clearance gauge according to the aequum of its single-piece, clearance gauge angle needs 180 ° of the corresponding one-tenth in duplicate removal position with turbocharger rotor axle.
The present invention, by rotor arbor wheel head is changed to hole, has not only alleviated weight, and operating efficiency improved a lot, and armature spindle outward appearance is totally beautiful, has greatly improved the service life of armature spindle, thereby the sales volume of product is greatly improved.
