As for the threaded sleeve, it is a new type of threaded fastener, which is a spring-shaped inner and outer thread concentric body precisely machined from stainless steel wire with high-precision diamond cross-section. Of course its performance is also very good. The following are the following methods of loosening stainless steel nuts: 1. On the mechanical parts loaded with metal or non-metallic materials (such as aluminum, magnesium and other light alloy engineering materials), it can form high strength, wear resistance, high precision standard internal thread. Such as applications: high-voltage switchgear, hydraulic machinery, welding equipment |, tobacco machinery, microwave communications, auto parts, air separation equipment, coal machinery, power machinery, textile and chemical fiber machinery, etc.
At present, many manufacturers do not want the product to be disassembled by the user, so they set the anti-disassembly mark on the product. The common method is to apply red or blue anti-disassembly paint on the fastener, such as the nut, once the user disassembles it by himself. , the paint at the connection will fall off, and it can no longer be aligned, so that the manufacturer can judge and identify it and provide a basis for warranty. However, it is inconvenient to paint some joints, and the use of tamper-evident paint is not healthy and environmentally friendly.
Cylindrical pins are widely used for positioning or connecting components on mechanical equipment, and the cylindrical pins are fixed in the pin holes by means of interference fit. Cylindrical pins are generally processed by a grinding machine and a punch former, but the above processing methods have complex operation procedures, high processing equipment and high processing costs.
At present, most of the cylindrical pin press-fitting is to put the product into the positioning position of the lower die first, and then take a cylindrical pin and put it into a cylindrical pin positioning hole that is concentric and perpendicular to the hole in which the product is pressed, or put it on the product. , the pin needs to have a positioning guide; or it is fixed on the top of the indenter so that it will not fall, and then the press is completed. In fact, it is difficult to press the small cylindrical pins. To ensure the good quality of the product, it is required to locate accurately, to ensure that the cylindrical pins are concentric and vertical, and to put the cylindrical pins one by one. It is very easy for workers to produce. Fatigue and low efficiency, product quality control is affected by many human factors, resulting in unstable product quality and certain safety hazards in work. On the other hand, in some production lines, the cost of the press-in cylindrical pins is relatively expensive, such as finger cylinders and moving mechanisms, which will put a lot of cost pressure on the equipment investment of small and micro enterprises.
In the process of driving the car, it is inevitable to use the brake frequently, which will cause the gap between the brake drum and the friction pad of the car to become larger. Therefore, it needs to be adjusted in time, otherwise, the hidden danger of unsafe driving will be buried due to the excessive braking distance and the out-of-round brake drum. Therefore, motor vehicles must be equipped with automatic adjustment arms. In the existing automatic adjustment arm, the worm inside the housing is limited by the spring pad, the spring and the spring cover, and the end face of the spring pad is directly in contact with the worm, and the rotation of the worm is inflexible due to frictional resistance during rotation.
