The invention discloses a full-floating type rear axle housing assembly half axle sleeve oil seal journal surface machining process. The process specifically comprises the steps of (1) basic treatmentof the surface of the oil seal journal, (2) deep grinding treatment of the surface of the journal, (3) oiling operation of the surface of the journal, (4) dynamic detection, (5) quenching treatment of a qualified journal, and (6) detection of a quenched product. The invention relates to the technical field of oil seal journals. According to the full-floating type rear axle housing assembly half axle sleeve oil seal journal surface machining process, the oil seal journal passes dynamic detection before being subjected to comprehensive quenching treatment; defective products can be effectivelyprevented from participating in quenching treatment, resource waste is avoided, the oil seal journal generates reliable pressure stress through quenching, the fatigue strength of the oil seal journalcan be improved, the faster cooling is, the more martensite is formed during spray cooling, the hardness of the journal is guaranteed, the journal is prevented from becoming brittle, and the overall strength of the oil seal journal in use is improved.

    本发明公开了一种全浮式后桥壳总成半轴套管油封轴颈表面加工工艺,具体包括如下步骤:步骤1:油封轴颈表面的基本处理,步骤2:轴颈表面的深度打磨处理,步骤3:轴颈表面的上油操作,步骤4:动态检测,步骤5:合格轴颈的淬火处理,步骤6:淬火后的产品检测,本发明涉及油封轴颈技术领域。该全浮式后桥壳总成半轴套管油封轴颈表面加工工艺,油封轴颈在进行全面淬火处理前通过动态检测,能够有效避免残次品参与淬火处理,避免了资源浪费,油封轴颈通过淬火产生可靠的压应力,可改善油封轴颈的疲劳强度,在喷淋降温时,冷却越快,马氏体形成越多,既保证了轴颈的硬度,又避免轴颈变脆,提高了油封轴颈使用时的整体强度。
