Machine tool soft connection is a device used to flexibly connect different parts or systems of machine tools. It is usually used to connect the moving parts and fixed parts of machine tools, allowing the equipment to produce small displacements or vibrations during operation without affecting the function of the connected parts or causing damage. The application of soft connection in machine tools can play a role in buffering, shock absorption, and displacement compensation, which helps to improve the stability and service life of the equipment.

The main functions of machine tool soft connection:

1. Shock absorption and noise reduction: When the machine tool is running, especially in high-speed processing or large movements, vibration and noise will be generated. Soft connection can effectively reduce these vibrations and reduce noise transmission.

2. Compensation displacement: Due to thermal expansion and contraction, vibration or movement, displacement may occur between machine tool parts. Soft connection can compensate displacement within a certain range to prevent stress concentration caused by rigid connection.

3. Sealing protection: In some occasions where sealing is required, such as liquid and gas transmission pipelines, soft connection can provide good sealing performance to prevent leakage.

4. Flexible adaptability: Soft connection has good flexibility and can adapt to the complex movement mode of machine tools to ensure coordinated work between moving parts.

Application scenarios of machine tool soft connections:
Hydraulic pipelines and pneumatic pipelines: In the hydraulic or pneumatic system of the machine tool, soft connections are used to connect pipelines to prevent pipeline rupture or loose interfaces caused by vibration or displacement.
Chip removal device: In the machine tool chip removal system, soft connections can be used to connect moving parts with chip removal pipelines to ensure smooth chip removal and withstand the displacement caused by machine movement.
Vacuum or cooling system: In the vacuum or cooling system, soft connections can connect vacuum cleaners or coolant supply systems to keep the equipment clean and prevent system leakage.

Types of machine tool soft connections:
1.Rubber Flexible Connectors: widely used in shock absorption, sealing and other occasions, with good elasticity and wear resistance.
2. Metal corrugated hose: suitable for high temperature or high pressure environments, usually used to connect fluid pipelines or systems requiring higher sealing performance.
3. Plastic hose: with the characteristics of corrosion resistance, light weight, good flexibility, etc., suitable for some light machinery or highly corrosive working environments.
4. Fiber-reinforced flexible connection: Through the design of the reinforcement layer, the compression and tensile resistance of the flexible connection is enhanced, which is suitable for occasions requiring high-strength connection.

Key points for selecting flexible connection:
Material selection: Select suitable materials such as rubber, metal, plastic, etc. according to the working environment of the machine tool to ensure that the flexible connection can withstand the pressure, temperature and chemical corrosion in the working environment.
Dimensions: Select the size and shape of the flexible connection according to the specific requirements of the machine tool equipment to ensure that it can adapt to the movement requirements of the equipment.
Service life: Choose a flexible connection with a long service life, wear resistance and fatigue resistance to reduce maintenance and replacement frequency.

Machine tool soft connection plays an important auxiliary role in modern machine tools and automation equipment. Its rational use can not only improve the performance and stability of the equipment, but also effectively reduce the maintenance cost of the equipment.
