I. Basic Maintenance (Every 3 Months) Suitable for stable daily production rhythms and even loads:
1. Clean the work surface and T-slots: Remove welding slag, oil, and metal debris to prevent blockages that could affect positioning accuracy.
2. Inspect fixtures and accessories: Confirm that pressure plates, positioning pins, quick clamps, etc., are free from wear, deformation, or looseness.
3. Lubricate moving parts: Apply special grease to guide rails, lead screws, bearings, etc.
4. Visually inspect the structural condition: Observe for localized wear, module misalignment, or loose connecting bolts.
This type of maintenance can be performed by operators during downtime, focusing on preventative maintenance.
II. Precision Calibration (Every 6 Months) To ensure welding positioning accuracy, regular professional testing is necessary:
1. Laser flatness measurement: Use a laser interferometer or 3D scanner to check the overall flatness. A deviation exceeding 0.05mm/m requires a warning.
2. Sensor Recalibration: For automatic positioning systems, this avoids clamping errors caused by signal drift.
3. Levelness Retest and Adjustment: Check the support condition of the feet to ensure the platform is under uniform stress.
It is recommended to schedule phased maintenance shutdowns in conjunction with the production plan, led by the equipment engineer.
III. Increased Maintenance Frequency in Special Circumstances
The maintenance cycle should be shortened to 1-2 months in the following situations:
1. Continuous operation exceeding 8 hours per day, or high frequency of bearing heavy workpieces;
2. Working environment with high levels of dust, moisture, or large temperature fluctuations;
3. Recent occurrence of off-center loading, impact, or significant deformation repair;
4. Fluctuations in welding accuracy, suspected to be related to the platform's condition.
In high-load scenarios, a "regional rotation + dynamic monitoring" strategy can be implemented to extend the overall service life.
