Type I hexagon nuts are the most widely used. Type 1 nuts are divided into three grades: A, B, and C. Among them, grade A and grade B nuts are suitable for machines, equipment and structures with small surface roughness and high precision requirements. Class C nuts are used on machines, equipment or structures with rough surfaces and low precision requirements.
The combination screw includes a head, a threaded section and a flanging section, the flanging section is arranged below the threaded section, and the flanging section and the threaded section pass through the mounting holes on the fittings, so that the combination screw and the fittings are rotatably connected, so After the flanging section passes through the fitting, the bottom of the flanging section is riveted and pressed so that the bottom of the flanging section is turned outward, so that the combined screw cannot be separated from the fitting.
rivet is a nail-shaped object with 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 semi-circular head, flat head, semi-hollow rivet, solid rivet, countersunk head rivet, blind rivet, hollow rivet, which usually use their own deformation to connect the riveted parts. Generally, cold riveting is used for those smaller than 8 mm, and hot riveting is used for larger ones. But there are exceptions, such as the nameplate on the three-ring lock, which is riveted by the interference between the rivet and the lock body hole. In addition, there are paired rivets, which are special. Divided into two parts, the thicker section of the rod with a cap has a hole in the center, and the other section of the rod with a cap is an interference fit. When riveting, drive the thin rod into the thick rod. Most of the existing rivets are connected by overall deformation to achieve mutual cooperation. In the ultra-fine-pitch display screen, the rivets used to fix the ultra-fine-pitch display screen have a slender diameter. If they are fixed by overall deformation, they are prone to bending and breaking. and other phenomena, the tightening effect is not good or there is no tightening effect, which damages the components, increases the cost, and wastes time and resources.
In the prior art, the spring washer has a certain anti-loosening effect. However, due to the unreasonable design structure, the upper and lower pressing forces of the spring washer and the spring washer's anti-return force are poorly matched, resulting in the smooth surface and the bolt head. The friction between the nut and the connected parts is small. When the bolt or nut is subjected to strong vibration, the bolt or nut will still loosen. Therefore, the anti-loosening effect of the above spring washer still needs to be improved.
Yueluo - a screw and nut disassembly tool for a narrow space, including a sleeve rod, a sleeve rod vertically arranged at one end of the sleeve rod, a connecting rod for fixedly connecting the sleeve rod and the sleeve rod, and a sleeve rod located at the end of the sleeve rod. The connecting rod in the axial through hole of the sleeve rod, the connecting rod located in the axial through hole of the sleeve rod, and the bearing for fixedly connecting the sleeve rod and the connecting rod and making the connecting rod rotate stably in the sleeve rod , and a sleeve head arranged at one end of the connecting rod, the connecting rod and the adjacent end of the connecting rod are provided with gears and the two gears are vertically meshed, so that when the external force drives the connecting rod to rotate, the force passes through The two gears and the connecting rod are transmitted to the sleeve head, thereby driving the screw or nut in the sleeve head to rotate;
