What is the tolerance range of precision screws?
On the other hand, when assembling many pin installation mechanisms, one end of the pin needs to be installed into the hole or arranged in the hole, and then the other end of the pin is applied to the pin through the pin installation mechanism, so that the pin is fixed in the hole. In the hole of the hole type product. This fixing method is not only extremely inefficient. And it is not possible to install multiple pins at once. Especially when exemplified at the other end of the pin, since there is nothing to hold the pin stable when the pin enters the hole type product, when force is applied to the other end of the pin, the pin can easily bend and damage the pin. .
As the requirements for the use of electrical appliances in various industries continue to increase, the testing specifications for the performance of various components in electrical appliances are also constantly improving. Riveted contact elements are used in various relays, contactors, small switches, thermostats, etc. in low-voltage electrical appliances. The structure of the riveted contact element generally includes a contact base and a rivet riveted to the contact base. The rivet includes a rivet head and a rivet top, the structure of which is shown in FIG. 1 .
Rivet nuts, pull caps, and instant pull caps are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, instruments, furniture, and decoration. It is developed to solve the shortcomings of thin metal plate and thin tube welding nuts, such as easy melting and easy sliding of internal threads. Chinese name rivet nut, foreign name Rivetnut, blinddrivetnut, threadedforbid, rivnut, also known as rivet nut, is used in various metal sheets, pipes and other manufacturing industrial applications in railways, refrigeration, elevators, switches
Alloy Steel Nuts Hexagon Nuts (GB6170/DIN934, GB6175), Flange Nuts (GB6177/DIN6923) Round Nuts (GB812), Small Round Nuts (GB810), American Square Nuts, American Hex Nuts (NI/MEB18.2.2), Heavy Duty Nuts (Metric, US). Specifications: 5/16-4. Nut Specifications Nut specification table is to unify all kinds of nuts in detail, and use the table to subdivide some specifications of nuts. There are many types of nuts, and there are nuts of different materials. Each type of nut has different specifications, and each type of screw also has its mechanical properties and functions.
