The invention belongs to the technical field of machining, and discloses a machining process and clamp for an eccentric shaft head assembly of an automobile rear axle housing assembly. The machining process comprises the following procedures of (1) cutting the length and punching a center hole; (2) roughly turning the small end; (3) finely turning the large end; (4) milling a chute; (5) fixing theassembling point of a shaft head and a flange; (6) boxing the flange; (7) finely turning the small end; (8) finely turning the reverse side; and (9) drilling a flange hole, wherein the machining reference is determined for each procedure around the diameter of the small end of the eccentric shaft head assembly of the automobile rear axle housing assembly, and the positioning reference of each procedure is consistent with the design reference of a part. According to the whole process, the machining reference is determined around the shaft neck of the small end of the eccentric shaft head assembly, the technological process is simple and effective, the product quality is stable, the productivity is improved, the production cost is reduced, and the design and use requirements are completelymet.
