Spring washers are often referred to as spring washers in the screw industry. It is made of stainless steel and carbon steel, and carbon steel is also known as iron. The commonly used spring washer specifications and sizes include M3, M4, M5, M6, M8, M10.M12, M14, M16. These specifications are more commonly used. The national standard GB/T 94.1-87 for spring washers specifies standard spring washers with a size of 2-48mm. Reference standard GB94.4-85 "Technical conditions for spring washers Spring washers"

A self-locking nut is a type of nut that can lock itself by friction. Generally, nuts will loosen themselves due to vibration and other reasons during use. To prevent this phenomenon, self-locking nuts were invented. The main function of self-locking nuts is to prevent loosening and vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with embedded nylon rings, those with neck closures, and those with metal anti loosening devices. They all belong to the effective torque type locking nuts (refer to the national standard GB/T3098.9-2002).

At present, with the development of the manufacturing industry, many strangely shaped components are widely used in industries such as aviation and aerospace. One type of L-shaped cylindrical pin requires a shaft at its lower end in design technology φ 2.54 ± 0.003, with 2.55 at the upper end × The "U" shaped boss of 4.95 requires a parallelism error of less than 0.01 millimeters between the upper and lower end faces of the boss. The L-shaped cylindrical pin requires high machining accuracy and is difficult to clamp on the machine tool, making it difficult to process. When cutting the formed part, a small pillar will be left on the cutting section, which is the upper end face of the boss. When processing this end face, in existing technology, the L-shaped cylindrical pin is generally clamped using a vice or copper sleeve, Then proceed with processing; However, due to the small external dimensions of the parts, the L-shaped cylindrical pin workpiece is difficult to clamp; Due to the high precision required for each machined surface of the workpiece, it is difficult to control the clamping force of the vice when clamping, which can easily crush and scratch the surface of the workpiece; And when using vises or copper set clamps, only one workpiece can be clamped during each processing and production. After the clamping is completed, it is difficult to ensure the parallelism of the upper and lower planes of the parts, resulting in low processing quality and low production efficiency.
