Service HotlineThe circlip is also called a retaining ring or a retaining ring. It is a kind of fastener and is installed in the shaft groove or hole groove of the machine and equipment to prevent the axial movement of the parts on the shaft or hole. The circlip includes an arc-shaped elastic bending portion and a circlip protrusion at the end of the elastic curved portion, and the circlip protrusion is provided with a small hole for matching with needle-nose pliers or circlip pliers. This part is a commonly used part on the equipment. Once the assembly is not in place, it will affect the overall performance of the equipment and cause safety hazards. At present, the most common assembly method is to manually clamp and deform the circlip with circlip pliers or needle-nose pliers, put the circlip into the annular groove of the inner hole of the end cover, and then release the needle-nose pliers or circlip pliers. . The assembly of the circlip is very troublesome, labor-intensive, and has low assembly efficiency. Once mass production is required, this process often becomes a bottleneck restricting production.
There are many names for screws in the scope of application. Everyone may have different names. Some people call them screws, some people call them screws, some people call them standard parts, and some people call them fasteners. Although there are so many names, but the meaning is the same, they are all screws. A screw is a generic term for a fastener. The principle of the screw is to use the physical and mathematical principles of the oblique circular rotation of the object and the friction force to gradually tighten the tool of the utensil. Screws are indispensable in daily life and industrial production, so screws are also known as the rice of industry. The scope of application of screws includes: electronic products, mechanical products, digital products, electrical equipment, electromechanical mechanical products. Ships, vehicles, hydraulic engineering, and even chemical experiments also use screws. There are many types of screws, whether it is a very small screw for glasses or a large screw for large heavy electrical engineering. The accuracy of screws is usually 6g (class 2, the American standard IFI is 2A teeth), and the rough screws used in construction projects are 1g. Screws are widely used, so the screw market is large, resulting in more manufacturers producing screws. When buyers choose a professional screw manufacturer, they need to understand some professional basic knowledge of screws, such as screw classification standard specification and American screw specification table.
Drilling screw is a new invention of people in recent years. A screw is a common term for fasteners, an everyday colloquial language. The tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination. It is easy to use safe drilling and tapping in one operation. Drill tail screw Drill tail screw use: It is a kind of screw, mainly used in the fixing of color steel tiles of steel structures, and can also be used for thin plate fixing of simple buildings. It cannot be used for metal-to-metal bonding. Materials and models The materials are iron and stainless steel, of which stainless steel is divided into various materials. Models are: Φ4.2/ Φ4.8/ Φ5.5/ Φ6.3mm, the specific length can be agreed upon request. According to the different drill tails, it can be divided into: round head rice / cross / plum blossom, countersunk head (flat head) / rice seed / cross / plum blossom, hexagonal washer, round head washer (big flat head), horn head, etc.
The tie rod and joint of the high-voltage isolating switch are often connected by driving an elastic cylindrical pin into the connecting pin hole. The traditional assembly method is to prevent the tie rod and joint from the V-block, and hold the elastic cylindrical pin to align the connecting pin hole. Then hit it with a hammer. Since the elastic cylindrical pin is small, it is easy to injure people's hands by adopting this assembly method, and at the same time, the elastic cylindrical pin is not positioned accurately, which causes large assembly errors and low assembly efficiency.
The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking is reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. Among them, the use of lock nuts is one of the anti-loosening measures. There are also two types of locking nuts. One is to use two identical nuts to screw on the same bolt, and a tightening torque is added between the two nuts to make the bolt connection reliable. The other is a special lock nut, which needs to be used together with a lock washer. As shown in FIG. 1, a plastic gasket 2 is arranged in the center of the nut 1 to play a locking effect, but the process is complicated and the production is inconvenient. One is to drill through threaded holes from the outer surface of the nut to the inner thread surface (usually 2, distributed at 90 on the outer surface), which are used to screw in small-diameter countersunk head screws. The purpose is to apply a thread to the thread. A centripetal force prevents the lock nut from loosening. At present, the lock nut with better quality on the market is inlaid with small copper pieces that are consistent with the thread of the lock nut on the inner surface of the nut, which is used to prevent the radial jacking screw from directly contacting the locked thread and being damaged. By. This kind of lock nut is gradually applied in the shaft end locking of rotating motion parts, such as the anti-looseness of the bearing at the mounting end of the ball screw. The process is equally complex.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: double-way nylon columns, elastic cotter pins, closed rivets, enlarged washers and other products, we can provide you with suitable fastener solutions for you Program.
