To facilitate the installation of other parts on the printed circuit board. The conventional process is to design prefabricated holes on the printed circuit board in advance, and squeeze the rivet nut into the board through pressure, so that the periphery of the hole is plastically deformed, so that the rivet nut is firmly fixed on the circuit board. In important positions, the use environment of pressure riveting nuts is relatively harsh. In display products, due to space constraints, pressure riveting screws are used a lot. The riveting quality of pressure riveting screws has a direct impact on the reliability of the system. The riveting process is correct. The key technology of using rivet nuts.
Among them, the pneumatic riveting machine is more commonly used. The pneumatic riveting machine is also equipped with a clamp for assembling the rivet. The existing clamp usually uses two rotating clamps for fastening and assembly, but the rotation easily causes the two clamps to buckle. Misalignment, thus affecting the assembly of the rivet.
The head of the traditional screw is located outside the threaded hole and occupies a large space, which is not suitable for occasions with small space, nor is it suitable for occasions where the outer surface of the component is a working surface. For example, in the field of electronic products, or when connecting the shaft and the shaft sleeve, the machine screw with a fully threaded structure on the outer surface is widely used.
T-bolts have been widely used in the fields of aviation, aerospace and defense due to their good positioning and anti-shedding effects. Its related standards have special requirements for accurate positioning, anti-falling off, and dimensional consistency of T-bolts. This requires that the position, size and shape and position tolerance of the anti-fall hole of the T-bolt shank must be controlled within a certain range. Therefore, the processing method of the anti-shedding hole is particularly important. Since the machined anti-shedding hole is located at the position of the rod, the milling processing efficiency is too low, the product cost is high, and there is a large machining error. When conventional drilling is used, the consistency of the anti-shedding hole size cannot be guaranteed. To solve the above problems of low efficiency and dimensional instability
rivet is a nail-shaped object used to join two parts or components with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal, commonly used are R-type rivets, fan rivets, blind rivets, blind rivets, tree rivets, semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, hollow rivets Rivets, these usually use their own deformation to connect the riveted parts. Generally less than 8 mm with cold riveting, larger than this size with hot riveting. But there are exceptions. For example, the nameplate on some locks is riveted by the interference between the rivet and the lock body hole.
