Step 11, uses round steel or bar to carry out the blanking of bearing pin.
Step 12, carries out the initial processing of appearance profile by lower good material, including the first car of the appearance profile to each section of bearing pin, and leaves suitable surplus.
Step 13, carries out modifier treatment to the part through initial processing.
Step 14, process described bearing pin head, each side including milling square spigot and the intersection to adjacent side carry out chamfering or rounding, and use milling cutter vertical with bearing pin but disjoint mode is directly to reach the purpose of the transient mode being again with rounding at described changeover portion two and the non-maximum outside diameter of the appearance profile of described bearing pin head.
Step 15, processes described thread segment two, described cylinder and described changeover portion one and described changeover portion two, including changeover portion two and cutting thread described in changeover portion one, car described in cylinder, car described in car.Wherein the processing sequence of changeover portion described in changeover portion one, car described in cylinder, car described in car can the most suitably adjust.
Step 16, carries out chamfering to the end of described cylindrical disconnected section or rounding processes.
Step 17, carries out polish to described cylindrical cylindrical, to ensure that its surface roughness reaches to use requirement.
Illustrate, in a step 11, the material manufacturing multiple bearing pins can be connected together, after experience step 12 to step 17, again each is nearly completed bearing pin separate, thus realize once can processing multiple bearing pin, improve efficiency.
Wherein, the manufacture method of axis pin base, comprise the following steps:
Step 21, axis pin base blank is processed, if having the needs of high intensity to axis pin base, is then carried out corresponding modifier treatment；Without high requirement, the most do not carry out modifier treatment.
Step 22, boring, bore described pin shaft hole and comprise the first time bottom outlet at described thread segment one and described circular hole, and exposed section each to hole chamfering deburring.
Step 23, reaming, the bottom outlet of thread segment one described in counterboring axially counterboring put in place.
Step 24, again reaming, circular hole described in counterboring axially counterboring put in place.
Step 25, fraising, including articulation pin shaft hole and circular hole, circular hole articulation axially puts in place but can not damage described conical ring hole two, and the technique guard space of reserved about 0.5mm between maximum distance and the conical ring hole two that circular hole is when articulation.
Step 26, tapping, carry out screw thread process including to thread segment one.
Step 27, is carried out each hole and thread segment one and does antirust treatment.
