Service HotlineBolts are widely used in the machinery industry. Round head bolts are generally fixed in equipment parts, but during long-term use, due to external force or vibration of the equipment itself, the bolts are loosened, and the bolt heads have a long-term use process. A fatal disadvantage is that it is prone to slippage, which can cause major safety hazards and economic losses to users in severe cases.
Dowels are made on the steering seat on the ball head of the car, and the rollers are assembled to the steering seat through the dowels. The prior art is manual driving of the pins, and the position of the pins is inaccurate when driving the pins, the labor intensity is high, the efficiency is low, and the quality of the steering seat is also affected. Therefore, it is necessary to design an automatic pin-driving mechanism to drive the pins into the steering seat. .
The above riveting requires special tools and equipment, which cannot be used in actual specific occasions. In the case of no electricity and no air, only manual tools can be used; and manual tools cannot be used for large types of rivets due to limited human strength. Moreover, after the rivet is disassembled, the rivet itself will be destroyed and cannot be reused.
The general nut will loosen itself due to vibration and other reasons during use. In order to prevent this phenomenon, the self-locking nut was invented. The main functions of self-locking nuts are anti-loose and anti-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 nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque type lock nuts (refer to GB/T3098.9-2002 national standard)
