Service HotlineIf the above-mentioned nuts and screws are used as a kind of fasteners that can prevent others from being disassembled, such as when installing iron doors-steel windows, people usually tighten the nuts first, and then use a welding machine to weld the nuts and screws. To prevent the nut from loosening, it may be necessary to use a tool to mill the threads on the screw. It can be seen that this approach is very inconvenient.
Yueluo also provides a thin plate rivet structure, which includes a metal thin plate and a rivet. The metal sheet is provided with a riveting hole; the riveting piece is penetrated in the riveting hole, the outer edge of the riveting piece is provided with an occlusal structure, and the inner edge of the riveting hole is embedded with the occlusal structure. A deformation groove is provided on the metal sheet, and the deformation groove is adjacent to the rivet hole.
nut is a connecting nut, a part that is screwed together with a bolt or connecting screw for fastening, and a component that must be used in all production and manufacturing machinery. There are many kinds of nuts, we commonly have standard, German standard, British standard, American standard, Japanese standard nuts. According to different materials, nuts are divided into carbon steel, high strength, stainless steel, plastic steel and other types. According to the product attributes, the corresponding standard numbers are divided into ordinary, non-standard, standard, new standard, American system, British system, and German standard. Different sizes, unequal threads are divided into different specifications. The general standard and German standard are represented by M, and the American system and the British system are represented by fractions or #. The specification nut is a part that tightly connects the mechanical equipment. Only through the inner thread, the same specification nut and screw can be connected together. The anti-loosening of the screw has always been the intersection of people's attention. The anti-loosening of the nut is of great significance to the current life, because it directly affects the service life of the machine. Therefore, it is also very important for people's life safety. Technicians can achieve the anti-feeding of the nut by changing the material of the nut and increasing the method of tightening the nut, but these methods cannot fundamentally solve the problem, and increase the tightening nut while taking up more space.
(1) The surface rust, oil stains, burrs on the wall of the bolt holes, welding flashes, etc. should be cleaned up. (2) After the contact friction surface is treated, the specified anti-scratch coefficient requirements must be met. The high-strength bolts used should have matching nuts and washers, which should be used in accordance with the matching and should not be interchanged. (3) When the friction surface of the treated component is installed, it is not allowed to be stained with oil, soil and other sundries. (4) The friction surface of the module should be kept dry during installation and should not be operated in the rain. (5) Strictly check and correct the deformation of the connected steel plates before installation. (6) It is forbidden to hammer into the bolt during installation to prevent damage to the bolt thread. (7) The electric wrench, which is regularly tested during use, ensures the accuracy of the torque and operates in the correct tightening sequence. Main safety technical measures (1) The size of the wrench of the adjustable wrench should be consistent with the size of the nut, and the sleeve should not be added to the small wrench. A dead wrench should be used for high-altitude work. For example, when using an adjustable wrench, use a rope to fasten it, and people should fasten their seat belts. (2) When assembling the connecting bolts of steel components, it is strictly forbidden to insert your hands into the connecting surface or touch the screw holes. When picking and placing the bolster, your fingers should be placed on both sides of the bolster.
In the current production process, the inner wall of the circlip is quantitatively and evenly lubricated, and then the rotating shaft is inserted into the circlip, so that the rotating axis can rotate in the circlip, thereby realizing the rotation function of the sun visor. However, since the circlip is tightly fitted with the rotating shaft, during the insertion process of the rotating shaft, the front end of the circlip can easily push the grease from the opening at one end of the circlip to the opening on the other end of the circlip, so that the rotating axis and the inner wall of the circlip are easily connected. There is little or no grease left between them, which can easily lead to a lack of lubrication between the shaft and the circlip, and dry friction between the shaft and the circlip, resulting in a series of problems such as abnormal noise, difficult operation, and poor durability.
