Such a structure is relatively complicated, and the design of the air circuit needs to be considered, and the phenomenon of material jamming is prone to occur, and it cannot be carried out due to the reason of the air circuit. Deep hole locking screws cause great trouble to users.
In the non-standard mechanical design, when the middle part of the long shaft or rod-shaped structure needs to be threaded, the end is limited and the nut cannot be penetrated, which will cause the problem that the installation cannot be realized. In order to solve this problem, it often has to be cancelled. It is not conducive to the realization of equipment cost reduction and optimal function, and even the problem cannot be solved, and another way out is needed.
As an important connecting part in the automobile assembly process, the screw plays a vital role in the safety performance of the automobile. The assembly of each component of the vehicle cannot be separated from the function of the screw. In the connection of the automobile assembly and its parts, the screw connection As well as simple structure, easy maintenance and disassembly, it is widely used. There may be thousands of screws on a car. The screw connection of each part has its own function and function. Once one or some screw connections fail, it will be It will lead to the loosening or even separation of the connected parts. If the car is running, it is likely to cause some parts to fail or break away. The light ones will cause the main functions of the car such as steering and braking to fail, potentially affecting driving safety. If it is not found in time, it will lead to major safety accidents and even endanger the lives of people. The failure of the car screws will cause the safety hazard of the whole vehicle, and will also cause customers to worry and complain, thus affecting the reputation of the company and endangering the life of the company. cycle.
At present, when using the existing screwdriver to install the screw, it is necessary to fix the screw with the left hand and turn the screwdriver with the right hand. However, in some places where the installation space is small and the installation is difficult, there are many areas that cannot be accessed by hands, and the installation is very difficult. For example, on an airplane, when installing with a common screwdriver, it is very difficult to install the screws and the installation efficiency is low because the screws cannot be positioned; in addition, when installing screws on the aircraft wing or fuselage, the combination between the screwdriver and the screw is easy to slip, The blade of the screwdriver slipped out and could easily bruise the hand and damage the aluminum skin of the aircraft.
Gaskets are mechanical seals between two objects, usually used to prevent pressure, corrosion, and natural thermal expansion and contraction of pipes between two objects and leakage. Since machining the surface is not possible, irregularities can be filled with spacers. Gaskets are usually made from sheet materials such as pad paper, rubber, silicone rubber, metal, cork, felt, neoprene, rubber, fiberglass or plastic polymers such as Teflon. Gaskets for specific applications may contain asbestos. The existing gasket is easily deformed for a long time in use, and the gasket cannot play the role of making up the difference. In addition, during the use process of the gasket, the adhesion between the gasket and the nut or the mechanical surface becomes poor, resulting in a poor sealing effect.
