There are many connection methods between the spring and the pin body of the spring limit pin, each with its own characteristics and applicable scenarios.
A common connection method is welding. By welding one end of the spring to the pin body, a relatively strong connection can be obtained. During the welding process, the spring and the pin body can be tightly combined and not easily separated. This connection method is more suitable for some occasions with high connection strength requirements, such as in heavy machinery. However, welding also has certain disadvantages. If the temperature is not properly controlled during the welding process, it may affect the performance of the spring, such as changing the elastic coefficient of the spring. Moreover, the connection part after welding is relatively hard. When subjected to strong impact or vibration, it may be more prone to problems such as breakage due to the lack of a certain elastic buffer.
Another connection method is mechanical nesting. A suitable groove or hole can be designed on the pin body, and one end of the spring can be inserted and fixed. This method is relatively flexible, and the spring can maintain its own elastic properties to a certain extent. It is also convenient when installing and replacing the spring. However, if the size of the designed groove or hole is not appropriate, the spring may not be firmly fixed, and the spring may shift or even fall off during use. Moreover, in long-term use, there is also a risk of loose connection due to the fact that the mechanical nesting part may be affected by friction and other factors.
There is also a way of connecting using a special snap-on structure. By designing a suitable snap or slot, the spring is snapped together with the pin body. This connection method is very convenient and quick during installation and removal, and can also provide a certain connection stability. The snap-on structure can allow the spring to have a certain amount of activity space to a certain extent, which is conducive to alleviating shock and vibration. However, the design and manufacturing precision of its snap-on parts are required to be high, otherwise it is difficult to ensure the reliability of the connection.
In general, there is no absolute most stable and reliable connection method, but it needs to be selected according to the specific application scenario. If the connection strength and stability are extremely high, welding may be an option, but attention should be paid to controlling the welding process. If the elasticity and replacement convenience of the spring need to be considered, mechanical nesting or snap-on structure may be more suitable. At the same time, in practical applications, the stability and reliability of the connection can also be improved through further optimization design and quality control.
