Embodiment Construction
[0011] Referring to the accompanying drawings, a method for processing a rear wheel hub of a heavy-duty vehicle is characterized in that it includes the following steps: 1. Countersign the blank drawing with the foundry to determine the casting requirements and rough machining benchmarks of the blank; 2. Use the workpiece flange end face A' 10 and outer circle A'9 are the rough datum, use CK50 CNC lathe to rough turn flange end face A12, outer circle A13, outer circle B' and end face 15, inner hole A and end face 17, inner hole D20 and workpiece end face A16, use Vernier caliper inspection; 3. Based on the processed flange end face A12 and outer circle A13, use CK50 CNC lathe to rough turn flange outer circle 11, flange end face A'10, outer circle A'9, workpiece end face A'4 , Inner hole A' and end face 5, inner hole C' and end face 6, inspected with a vernier caliper; 4. Based on the processed flange end face A12 and outer circle A13, use CK50 CNC lathe to fine-turn flange out...

The invention discloses a method for processing a rear hub of a heavy truck. The method comprises the following steps of: 1, roughly turning a flange end face A, an excircle A, an excircle B' and end face, an inner hole A and end face, an inner hole D and a workpiece end face A by taking a flange end face A' and an excircle A' as the roughing standard; 2, roughly and finely turning a flange excircle, the flange end face A', an excircle A', a workpiece end face A', an inner hole A' and end face, an inner hole C' and end face and an excircle slot by taking the flange end face A and the excircle A as the standard; 3, finely turning the flange end face A, the excircle A, an excircle B' and end face, an inner hole A and end face, an inner hole B and end face, an inner hole C and end face, the inner hole D and the workpiece end face A by taking the flange end face A and the excircle A as the standard; 4, positioning by the inner hole C and the flange end face A, and reaming flange side holes; 5, positioning by the processed inner hole A', the flange end face A' and one of the flange side holes, and drilling blind holes; and 6, inspecting and warehousing. The method disclosed by the invention has the characteristics that the production efficiency is high, the processing accuracy is high, and the processing cost is low.
Description
Technical field: [0001] The patent of the present invention relates to a processing method of auto parts, in particular to a processing method of a rear wheel hub of a heavy-duty vehicle. Background technique: [0002] The rear wheel hub of a heavy-duty vehicle is an important part of a newly developed heavy-duty vehicle product. The dimensional tolerance accuracy and shape tolerance accuracy of the wheel hub will have an important impact on driving, because the diameter of the wheel is fixed, and the size of the hub diameter affects the tire. The sidewall of the tire is affected by acceleration, braking, and turning during driving. Once the processing quality of the part cannot be guaranteed, the product quality will be poor and the service life will be short, which will seriously endanger the driving safety and bring great losses to the enterprise and society. Invention content: [0003] The purpose of the present invention is to provide a set of processing method for t...
