[0002] Locknuts are nuts that are screwed together with bolts or screws to tighten. They are a must-have for all manufacturing machinery. Locknuts are parts that tightly connect mechanical equipment. Through the inner thread, locknuts and screws of the same specifications can be connected together. Locknuts are widely used in 3C, bicycles, skating and skiing equipment, furniture, sports equipment, medical equipment and other industries. Locknuts have the following advantages: first, excellent vibration resistance; second, strong wear resistance and shear resistance; third, good reusability.
[0003] The cross-section of the anti-loosening nut is hexagonal, and the corners at the end are relatively sharp. In order to improve the safety during subsequent assembly, it is usually necessary to round the ends of the anti-loosening nut. At present, the rounding of the ends of the anti-loosening nut is usually done by turning or milling. During turning, the anti-loosening nut is clamped on a lathe, and the lathe drives the anti-loosening nut to rotate, and the turning tool is used to turn the rounded corners of the end of the anti-loosening nut; during milling, the anti-loosening nut is clamped on a milling machine, and the milling machine drives the tool to rotate, and the rounded corners of the end of the anti-loosening nut are milled. Although the CNC lathes and milling machines in the prior art can realize automated processing, the anti-loosening nuts still need to be clamped and processed one by one, and there are still certain limitations in processing efficiency. For this reason, we propose a anti-loosening nut rounding processing equipment to solve the above problems. Utility Model Content
