Description

Technical Field

[0001] This utility model relates to the field of nut and washer processing technology, specifically a press-fitting machine for automotive wheel hub nut and washer. Background Technology

[0002] Wheel nuts are critical fasteners on vehicles, securing the wheel to the hub in conjunction with wheel bolts and bearing dynamic loads during driving. Their structure typically features a tapered polygonal design with fine threads (1.5-2.0mm pitch) to enhance connection strength. Some models include a nylon washer step for locking. High-strength alloy steel or stainless steel are commonly used to ensure durability, and sizes range from M12 to M42 to accommodate different vehicle models. During production, a press-fitting machine is used to press the washer and nut together.

[0003] In most current nut and washer pressing processes, the washer and nut are placed on top of each other by the self-overlapping of the washer. During the pressing process, personnel need to manually place the washer on top of the nut. However, the efficiency of placing them one by one manually is low, which affects the work efficiency. In addition, in order to make the washer and nut stack concentrically, additional time is required, which makes the work efficiency low and increases labor and time costs.

[0004] Therefore, this utility model provides a press-fitting machine for automotive wheel hub nut washers to solve the above problems. Utility Model Content
