I. Regular Inspection Cycle and Content
1. Quarterly Comprehensive Inspection:
Surface Accuracy and Flatness: Use an autocollimator to measure the platform's flatness, ensuring the error is ≤0.15mm/m².
Positioning Holes and T-Slots: Check if the gap between the Φ28 hole system has increased, and whether the T-slot dimensions meet the requirements.
Support Points: Use a 0.05mm feeler gauge to check the gap between the support points and the platform base. If the gap exceeds the tolerance, tighten or replace the hydraulic support.
2. Shortened Cycle for High-Frequency Use:
If the platform is used frequently, the inspection cycle can be shortened to once a month, focusing on checking the straightness of the guide rails and the electrical system.
II. Maintenance of Key Components
1. Guide Rails and Support Points:
Guide Rail Jamming: Use a laser interferometer to measure the straightness error (≤±0.02mm/m), clean and re-lubricate the guide rails.
Loose Support Points: Check the locking device to ensure the stability of the hydraulic support.
2. Electrical System:
Insulation Resistance: Test the insulation resistance of the control board to ground using a 500V DC insulation resistance tester (≥1MΩ).
Voltage Stability: Check the main power input voltage fluctuation (±10% of rated value) and the 24V DC control circuit (24V±5%).
III. Daily Maintenance and Care
1. Cleaning:
Clean welding slag after each use. Deep clean the welding torch head quarterly.
Use compressed air to blow away accumulated dust inside the welding machine, paying special attention to cleaning the transformer, reactor coils, etc.
2. Replacement of Wear Parts:
Regularly inspect and replace easily worn parts such as the torch head, chuck, and ceramic ring.
Inspect the wear of the wire feed roller grooves; clean or replace the wire feed rollers.
IV. Precautions and Precautions
1. Environmental Control:
Maintain a stable operating temperature (10–30℃) to avoid thermal deformation affecting test results.
Avoid humid environments to prevent electrical malfunctions.
2. Operating Procedures:
Avoid damaging the cables; keep the welding torch vertical during welding.
Strictly control the workpiece assembly accuracy (±0.8mm) to avoid inaccurate welding torch contact points (TCP).
3. Records and Archives:
Establish equipment health records, recording data from each inspection and maintenance.
For equipment with long service life and frequent malfunctions, obtain approval from the company's production department for technical upgrades or replacements.
