Plug GaugeHarmony Gauge Is A Commonly Used Measuring Tool In Mechanical Processing And Inspection, Mainly Used To Measure The Aperture And Shaft Diameter Of Workpieces To Ensure That They Meet The Specified Size And Tolerance Requirements.
Plug Gauge
A Plug Gauge Is Used To Measure The Aperture Of A Workpiece, Usually Consisting Of Two Ends:
Communication End: Used To Detect The Minimum Allowable Size Of The Aperture, Which Should Be Able To Smoothly Pass Through The Tested Hole.
Stop End: Used To Detect The Maximum Allowable Size Of The Aperture And Should Not Pass Through The Tested Hole.
If The Through End Can Pass But The End Cannot, It Indicates That The Aperture Is Within The Tolerance Range And Qualified.
Ring Gauge
The Ring Gauge Is Used To Measure The Shaft Diameter Of A Workpiece And Is Also Composed Of Two Ends:
End: Used To Detect The Maximum Allowable Size Of The Shaft Diameter, It Should Be Able To Smoothly Fit Into The Tested Shaft.
Stop End: The Minimum Allowable Size For Detecting Shaft Diameter And Should Not Be Fitted Into The Tested Shaft.
If The Through End Can Be Inserted But The End Cannot Be Inserted, It Indicates That The Shaft Diameter Is Within The Tolerance Range And Qualified.
Application Scenarios
Plug Gauge: Commonly Used For Detecting Hole Type Parts, Such As Bearing Holes, Pin Holes, Etc.
Environmental Gauge: Commonly Used For Detecting Shaft Components Such As Shaft Diameter, Pin Shaft, Etc.
Precautions
Cleaning: Before Use, Ensure The Cleanliness Of The Plug Gauge And Ring Gauge To Avoid Impurities Affecting Measurement Accuracy.
Temperature: Measurement Should Be Carried Out At Standard Temperature To Avoid Thermal Expansion And Contraction Affecting The Results.
Strength: When Using, The Strength Should Be Moderate To Avoid Damaging Measuring Tools Or Workpieces.
Maintenance
After Use, It Should Be Cleaned And Coated With Anti Rust Oil, And Stored In A Dry Place.
Regular Calibration To Ensure Measurement Accuracy.
Plug Gauges And Ring Gauges Are Important Tools For Ensuring That The Dimensions Of Workpieces Meet The Requirements. Proper Use And Maintenance Can Effectively Improve Product Quality And Production Efficiency.
