The Spring-Return Single-Acting Hydraulic Cylinder in Robotics
Introduction
Spring-return single-acting hydraulic cylinder is a type of hydraulic cylinder that utilizes hydraulic oil to extend the piston. The built-in spring automatically retracts the piston when pressure is released.
Design and Construction Characteristics
- Single-acting Structure: Hydraulic oil pressure extends the piston, while return depends on the built-in spring.
- Spring Selection: Appropriate spring choice ensures quick and complete reset after pressure release.
- Sealing Design: High-quality seals prevent oil leakage for efficient and safe operation.
- Strength and Durability: Material selection considers high pressure and impact resistance, often using high-strength steel.
Construction and Assembly Process
- Assembly Precision: Components must be precisely aligned to reduce friction and wear.
- Welding and Connection: Strong welds and connections prevent oil leakage under high pressure.
- Testing and Debugging: Pressure and functional tests ensure proper operation.
Working Principle
The single-acting mechanism of the hydraulic cylinder extends the piston with hydraulic oil and retracts it using the spring mechanism.
