Service HotlineNuts are a commonly used fastening parts and are widely used in various mechanical and electrical equipment. Common application equipment does not have particularly strict requirements on the anti-loosening properties of nuts, but for automobiles, high-speed railways, aerospace and nuclear power and other fields, many equipment or components work in a vibration environment for a long time, and it is easy to loose between bolts and nuts. This will affect the normal operation of the equipment and even cause safety accidents.
The existing adjusting screw is generally composed of a screw and a nut on the top of the screw. The screw is driven to rotate by means of a screwdriver, and then the screw is driven to rotate. In and out, adjusting other objects connected to it and changing position accordingly.
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 (ANSI/ASME B18.2.2) , Heavy-duty nuts (metric, US). Size: 5/16-4.
The defect of the existing press-fit solution is: when the retaining ring is placed in the chamfering section or the guide section of the shaft head, the retaining ring cannot be accurately fixed, and the retaining ring is easy to tilt or fall, especially when the shaft head is located inside the bearing chamber depression, The inclination of the retaining ring will make it difficult to press the retaining ring, affect the production efficiency, and even cause the product to be scrapped.
As we all know, whether it is the necessities in people's life or the equipment in industrial production, there will be a structure of screws and screw holes on it. This kind of structure that can simply fix some components together has been widely used in various fields. For the installation and removal of screws, people invented manual screwdrivers, and then to electric screwdrivers and so on. For manual screwdrivers, the operator needs to manually install or remove the screws. When encountering small screws, it can still handle it. When encountering large screws, due to people's limited strength, they may not install the screws in place, so it was invented. Electric screw. When installing the screw, which is widely used in the market, the operator needs to hold the screw handle, fix the screw on the screw port, and then align the screw with the corresponding screw hole for screwing. The disadvantage of this kind of screw is that it is heavy in quality and laborious to operate, and secondly, the operator will be injured due to operating errors, and the consequences are extremely serious. In view of this deficiency, people fix the screws on a work frame, so that before installing the screws, the operator only needs to adjust the screws to the designated position, and then the screws can be installed, which is convenient and simple. However, there are still potential safety hazards. In the process of adjusting the screw, it is still possible that the power of the screw may be turned on by mistake due to operating errors, resulting in injury to the operator. In view of the above-mentioned defects, it is necessary to invent a screw installation method with an anti-missing function.
