Component Maintenance of Drilling Machines in Stone Quarrying
Drilling machines are critical tools in stone quarrying, used for tasks such as creating holes for explosives, attaching wire saws, and obtaining core samples. The maintenance of these machines is essential to ensure their longevity, safety, and efficiency. Here's an overview of the key components of drilling machines and how to maintain them.
1. Drill Bits and Hammers
Maintenance:
Regularly inspect for wear and tear.
Replace when the cutting edge is (blunt) or damaged.
Clean to remove dust and debris after each use.
2. Pistons and Cylinders
Maintenance:
Check for any signs of leakage or damage.
Lubricate regularly to reduce friction and prevent wear.
Replace seals and gaskets as needed to maintain proper pressure.
3. Feed Mechanisms
Maintenance:
Ensure that all gears, screws, and rods are clean and properly lubricated.
Check for any signs of binding or excessive play in the feed system.
Adjust or repair as necessary to maintain accurate and smooth operation.
4. Hydraulic Systems
Maintenance:
Check hydraulic fluids for contamination or degradation and replace them as needed.
Inspect hoses and fittings for leaks or damage.
Service hydraulic pumps and motors according to the manufacturer's recommendations.
5. Electrical Systems
Maintenance:
Inspect electrical cables for wear or damage and replace them if necessary.
Check all switches, relays, and connections for proper function.
Ensure that all components are clean and free from dust or debris that could cause short circuits.
6. Chassis and Frame
Maintenance:
Inspect the chassis for cracks, deformations, or excessive wear.
Check for proper alignment of all components mounted to the frame.
Clean and paint as necessary to prevent rust and corrosion.
7. Air Systems
Maintenance:
Check air filters and replace them if clogged or damaged.
Inspect air compressors for proper operation and output.
Ensure that all air lines and fittings are secure and leak-free.
8. Control Systems
Maintenance:
Check all control levers, buttons, and switches for proper operation.
Lubricate control linkages and adjust as necessary.
Update or repair any electronic control systems as needed.
1. Maintenance of lead screws and guide rails
(1) Regularly check and adjust the axial clearance of the lead screw nut to ensure the reverse transmission accuracy and axial stiffness;
(2) Regularly check whether the connection between the lead screw support and the bed is loose and whether the support bearing is damaged. If there are any of the above problems, the loose parts should be tightened in time and the support bearings should be replaced;
(3) For ball screws with grease, clean the old grease on the screw every six months and replace it with new grease. Ball screws lubricated with lubricating oil, lubricated once a day before the machine tool works;
(4) Pay attention to avoid hard dust or chips from entering the screw protective cover and hitting the protective cover during the working process, and replace the protective device in time if it is damaged.
2. Maintenance of the drive shaft
(1) Regularly adjust the tightness of the spindle box and the spindle drive belt;
(2) Check whether the spindle has axial channeling;
(3) Check and adjust the spindle clearance;
(4) Prevent all kinds of impurities from entering the fuel tank. Lubricating oil should be changed once a year;
(5) Keep the connection between the spindle and the tool holder clean. The displacement of the cylinder and piston needs to be adjusted in time.
