What is the tolerance range of precision screws?
At present, in the era of industrialization, rivets used in specific occasions, automobiles, and aviation industries can only rely on professional tools and equipment to complete the riveting method.
In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts.
When the iron pot is manufactured, the iron head is connected to the iron pot body through rivets, and then the pot handle is set through the iron head, and the iron head connects the pot handle and the iron pot body together. However, when the iron head is installed, the position may be inaccurate. At this time, it is necessary to remove the rivet and reinstall the iron head. At present, the removal of rivets is completely done manually, that is, workers use screwdrivers to unscrew the rivets, which is difficult to remove, wastes a lot of manpower, and has low work efficiency, thereby reducing production efficiency.
The gasket is a part that is placed between the connector and the nut, and is generally a flat metal ring. Gaskets are used for mechanical seals between two objects, usually to prevent pressure, corrosion, and natural thermal expansion and contraction of pipes between two objects and leakage. Since machining the surface is not possible, irregularities can be filled with spacers. Gaskets are typically made from sheet materials such as backing paper, rubber, silicone rubber, metal, cork, felt, neoprene, rubber, fiberglass, or plastic polymers such as Teflon, application-specific gaskets May contain asbestos. Other uses are as spacers, springs (Belleville spacers, wave spacers), wear pads, pre-display devices, lock devices. Rubber gaskets are also used in faucets (valves) to cut off the flow of liquid or gas, and rubber or silicon gaskets are also used to reduce fan vibration. The function of ordinary gaskets is not good, the gaskets are easy to slip during the nut pressing process, the tightening effect is poor, the wear resistance of the gaskets is not good, and it has no anti-interference effect when used in electronic components.
