Abstract
The invention provides a car transmission shaft machining technology which comprises the steps of forging, normalizing, rough turning, finish turning, deep hole drilling, hobbing, oil hole drilling, and then a series of washing of degreasing pretreatment, degreasing, hot water washing, cold water washing, activating treatment, ultrasonic rinsing, chemical agent washing and drying. A washed transmission shaft is clamped to a rotor of a machine tool, laser is used for carrying out irradiating with the intersection angle of 78-85 degrees on the annular surface of a rotating transmission shaft, when the temperature of a light spot center point of the annular surface which is hardened by heating reaches 1000-1200 DEG C, irradiating is over, and hardening is finished. Then, an outer circle grinding procedure is carried out, an outer circle which needs matching is ground to be in a certain shape, and finally a finished product is obtained. According to the car transmission shaft machining technology, the inner quality and the outer quality of the transmission shaft are both improved.
Description
Technical field
The present invention relates to a kind of vehicle transmission axis processing technique, belong to Manufacturing Technology for Automotive Parts field.
Background technology
Truck drive shaft operationally withstands shocks, the effect of reversed bending fatigue load and moment of torsion, requires that material has enough bending strengths, shearing strength and good toughness.Truck drive shaft not only requires high in inherent quality, and the pursuit of Surface Quality is more and more higher, and wherein phosphating process is common technology of the prior art, but backward in technique.
Summary of the invention
The invention provides a kind of vehicle transmission axis processing technique, be a kind of novel manufacturing processing technic, and surface quality is further improved.
In order to solve the problem, the technical solution used in the present invention is: a kind of vehicle transmission axis processing technique, comprises the following steps: forging, selects low-carbon alloy Steel material, according to the pre-made allowance of drawing requirement, and forging and molding; Normalizing, carries out normalized treatment to the product of forging and molding, refinement harmful structure, eliminates banded structure and the Wei Shi body of forging formation, adopts 905 DEG C of-915 DEG C of high temperature normalizings in normalizing process; Rough turn, remove a large amount of surplus, cylindrical, end face are carried out preliminarily forming, the monolateral reserved allowance of product is 0.75-1mm, and roughness is Ra6.3; Finish turning, cylindrical, end face are shaped according to technical requirement finish turning, the product surface roughness that finish turning is shaped is Ra1.6; Drilling deep hole, gets out the deep hole of power transmission shaft; Gear hobbing, adopts gear-hobbing machine to roll out the spline of power transmission shaft; Bore oilhole, according to requiring to get out oilhole on power transmission shaft, then carry out degreasing pre-treatment, degreasing, hot water cleaning, cold water cleaning, activation process, ultrasonic rinsing, chemical agent cleaning and dry a series of cleaning; Cleaned drive shaft cartridge is clipped on the rotor of lathe, carry out facing to the place to be hardened of the power transmission shaft annular surface be rotating the irradiation that the angle of cut is 78-85 ° with laser, when the temperature of this point of spot center by the annular surface of thermmohardening reaches 1000-1200 DEG C, irradiate and terminate, sclerosis completes; Carry out cylindrical grinding operation again, the cylindricalo grinding needing to coordinate is shaped, finally obtains finished product.
