Service HotlineNuts are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specification can be connected together. At present, most nuts are used together with gaskets when they are locked, or are set as an integrated structure, which has the advantage of increasing Friction, strengthen the effect of tightening, but the square nut is usually used directly without adding a gasket, and the upper and lower end faces are flat, very smooth, when subjected to strong vibration, it is very easy to loosen, and the tightening effect is not good.
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 (NI/MEB18.2.2), Heavy Duty Nuts (Metric, US). Specifications: 5/16-4. Nut Specifications Nut specification table is to unify all kinds of nuts in detail, and use the table to subdivide some specifications of nuts. There are many types of nuts, and there are nuts of different materials. Each type of nut has different specifications, and each type of screw also has its mechanical properties and functions.
The material of the second combination screw: It is decided to use the test machine to test the material of the combination screw wire, which is divided into iron and stainless steel. Iron wire is divided into 1010 wire and 1018 wire, 10B21 wire, etc., stainless steel is divided into stainless steel 201, stainless steel 304, stainless steel 316 and so on. The provisions of the national label of three combination screws: Generally, those who have experience in combination screws can be separated by using the inner eye. The difference between hexagon heads. Use a caliper to measure out the three-combination screw specifications. How big is it, how long is it, how thick is the head of the combination screw, how thick is the flat washer, and what is the outer diameter of the flat washer. How many hours is the salt spray of the combination screw measured with a salt spray machine. Use the environmental test machine to test whether the three-combination screw is environmentally friendly. Still not environmentally friendly.
In the prior art, the screw suction device can be implemented in the following two ways. One is to use a magnet to magnetize the electric bit head, and the electric bit head is used to approach the screw, and the screw is stuck by the electric bit head, so that the function of picking up the screw can be realized; The vacuum generator is used to form a negative pressure in the screw guide groove, and the screw is sucked into the tube to realize the screw pickup. The disadvantage of this solution is that in the process of picking up the screws, the grooves of the screws cannot be aligned, which leads to the deviation or leakage of the screws. The disadvantage of this solution is that the screw with an aspect ratio of less than 1.8 is prone to suction and skew, and the stability is not high. It can be seen that the existing technology still needs to be improved and developed.
Anti-loose washers are also known as anti-loose washers, self-locking washers, self-locking gaskets, DIN25201 anti-loose washers, double-stack self-locking anti-loose washers, double-stack wedge-type anti-loose washers, etc.
