The main connection methods between cylinders and pistons are as follows:
1、 Pin connection
Principle: Connect the piston and cylinder using pins that match the piston pin holes on both sides.
characteristic:
Advantages: Simple connection, while ensuring the position of the piston in the cylinder.
Disadvantage: It is easy to cause the piston to tilt and get stuck.
Installation points: The diameter of the pin should be slightly smaller than the diameter of the pin hole, so that the pin can be installed smoothly in the pin hole; The length of the pin should be about 2mm deeper than the pin hole.
2、 Pin tooth connection
Principle: Using a pin ring structure, the piston and cylinder are tightly connected together.
characteristic:
Advantages: The connection is tight, which can prevent the piston from tilting or getting stuck in the cylinder.
Disadvantage: Compared to plug-in connections, the structure may be more complex.
Application: This is a new type of piston and cylinder connection method, suitable for situations that require high connection tightness.
3、 Threaded connection
Principle: Thread is set at the head of the piston rod to connect the piston to the piston rod (and then to the cylinder) through the thread.
characteristic:
Advantages: High universality, most standardized cylinders adopt this form; The connection is firm and reliable.
Disadvantage: It is necessary to ensure the accuracy and fit of the threads to avoid looseness or leakage.
Installation points: When connecting, appropriate thread fastening adhesive should be used and tightened strictly according to the specified torque to prevent loosening.
4、 Other connection methods
In addition to the common connection methods mentioned above, there are also some special cylinder and piston connection methods, such as through rod connection, flange connection, half ring connection, etc. These connection methods each have their own characteristics and are suitable for different application scenarios
5、 Installation precautions
Regardless of the connection method used, the following points should be noted when installing cylinders and pistons:
Check parts: Before installation, carefully inspect the cylinder, piston, piston rod and other parts for damage or wear to ensure their integrity.
Cleaning and lubrication: Before installation, the cylinder and piston should be cleaned to remove dust and dirt; At the same time, lubricate the parts that require lubrication to reduce friction and wear.
Correct installation: Install according to the prescribed installation steps and requirements to ensure a firm and reliable connection between the cylinder and piston.
Adjustment test: After installation, necessary adjustments and tests should be made to the cylinder and piston to ensure their flexible movement and good sealing.
In summary, there are various connection methods between cylinders and pistons, each with its own characteristics and applicable scenarios. When choosing a connection method, comprehensive consideration should be given to specific application requirements and working conditions.
