Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a surface processing technology for the oil seal journal of the half-axle casing of the full-floating rear axle housing assembly, which solves the problem of the oil seal shaft of the half-axle casing of the ordinary full-floating rear axle casing assembly. When the neck is in use, it is often put into production directly, and its inner surface is not subjected to secondary processing, and its own hardness is often affected after production, and there is a lack of inspection in production, and a large number of defective products will enter the complete production process, causing serious waste. The problem of production resources

Embodiment 1

[0029] Step 1: Basic treatment of the surface of the journal of the oil seal: Use a soft clean cloth to clean the surface of the journal comprehensively, and conduct a comprehensive inspection on the surface after cleaning to determine the protruding particles on the surface of the journal, and then check the convex particles on the surface of the journal. Metal particles are removed for removal;

[0030] Step 2: Deep grinding treatment on the surface of the journal: Use a grinder to grind the horizontal lines on the surface of the journal first. After the grinding operation, use the grinder to grind the vertical lines on the surface of the journal. When both are polished, the qualified product records;

[0031] Step 3: Oiling operation on the journal surface: each time use a soft cloth with a surface area of ​​100 square centimeters to absorb 20 grams of lubricating oil, and evenly oil the journal surface. After oiling, perform a static inspection of the basic dimensions of t...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of oil seal journals, in particular to a surface processing technology for oil seal journals of half shaft casings of a full-floating rear axle housing assembly. Background technique [0002] The production process of a machine refers to the entire process of making a product from raw materials (or semi-finished products). For machine production, it includes transportation and storage of raw materials, production preparation, blank manufacturing, processing and heat treatment of parts, product assembly, debugging, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, and regard the production process as a production system with input and output. The journal is generally where the bearing is mounted on the shaft. Refers to a shaft with the same diameter on the shaft or a...
