What is the tolerance range of precision screws?
In mechanical devices, there are many ways to install and connect two components, such as bolt connection, welding, etc., but for installation and connection in a narrow space, such as the socket of two hollow cylinders with smaller diameters, due to the relatively small space It is very difficult to use this method, and it is extremely inconvenient to install and connect.
At present, during assembly of many pin installation mechanisms, the pins need to be installed into the holes or arranged in an orderly manner, and there are many problems in this assembly method. First of all, during assembly, if the hole diameter of the hole product is large, when the pin enters the hole of the hole product, part of the pin entering the hole of the hole product is not fixed, which often leads to slight deviation. In addition, this assembly method is usually only suitable for parts with large apertures and small depths, and when installing multiple pins, it is impossible to automatically install all pins in place due to space constraints. Special tools need to be made for installation operations, and it is easy to cause pins. damage.
Traditionally, the pressure rivets on the product are all beaten by hand by workers, resulting in high scrap rate and low efficiency, and this rivet is not a traditional rivet, so it is difficult to locate and requires high pressure. The rivets are thin, and the pressure is too large to cause deformation of the rivets. If the pressure is too small, it cannot be riveted. Without special positioning and tooling, it cannot be riveted on the riveting machine. The quality of the products produced in this way is difficult to guarantee, and the quality levels of the products in the same batch are uneven. Affect delivery time.
Riveting products provide great convenience for the unilateral connection of sheet parts, fast and efficient connection without bulky installation tools, and produce reliable standard internal and external threads, achieve cold installation after surface treatment, no pollution, is welding Effective alternative to nuts. Main applications: Auto-body, seat belt systems, bumpers, airbag systems, etc. 1. One-way drawing connection 2. Build standard internal and external threads 3. General product range: M3-M124. Materials: Carbon Steel, Stainless Steel, Aluminum 5. High quality air tools - efficient, economical, lightweight and easy to operate. Use the same principle as hand rivet nuts.
