Here is a detailed introduction to the vertical servo press-fitting equipment used in assembly lines, including its structure, working principle, features, advantages, and a detailed parameter table.
Equipment Overview
The vertical servo press-fitting equipment is a high-precision, high-efficiency automated assembly machine widely used in industries such as automotive, electronics, and motors. It achieves precise press-fitting of components through a servo motor driving a ball screw, and it is equipped with real-time data acquisition and analysis capabilities to improve production efficiency and product quality.
Equipment Structure
- Main Body: Typically constructed with a column or four-column structure for high rigidity and stability. The core components include a servo motor and a high-precision ball screw, which drive the press head’s vertical movement.
- Control System: Comprises servo press-fitting software, a control box, and a human-machine interface module. It uses a modular closed-loop servo control system to collect and analyze force, displacement, and time data in real-time.
- Sensors: Equipped with high-precision load cells and encoders to accurately measure pressure, position, and speed during the press-fitting process.
- Safety Devices: Usually includes infrared safety light curtains and removable protective screens to ensure the safety of operators.
Working Principle
- Drive Mechanism: The servo motor drives the ball screw, controlling the press head’s position and speed by regulating the motor’s rotation angle and speed.
- Press-Fitting Process: The process includes several stages: fast approach, contact detection, press-fitting, cushioning, holding pressure, and return. The press head first moves down quickly to the detection position, then switches to the press-fitting speed upon contact with the workpiece, holds pressure after reaching the set position, and finally returns.
- Data Acquisition and Analysis: During press-fitting, the system collects pressure and displacement data in real-time, generating a press-fitting curve displayed on the touch screen. By analyzing this curve, the quality of the product can be determined.
Features
- High Precision Control: Position repeatability reaches ±0.01mm, and pressure accuracy is within ±1%.
- Flexible Production: Multiple press-fitting programs can be set, allowing one machine to handle various tasks and easily complete multi-stage press-fitting operations.
- Energy Efficiency: Compared to traditional hydraulic or pneumatic press-fitting machines, energy savings can reach 50%-80%.
- Data Management: Press-fitting data can be stored, exported, and uploaded to MES systems for production quality control and traceability.
- Safety Protection: Equipped with comprehensive safety devices to ensure the personal safety of operators.
