Surface Roughness Tester Skid Cleaning via Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foreign substances, such as coolants, adhere to the surface of machined work, entering the gap between the skid aperture and stylus of a surface roughness tester, leading to declined measurement performance.
Innovation Solution
A method involving a foreign substance removing section, including a suction device, air jetting device, or ultrasonic wave cleaning device, is used to remove foreign substances from the gap between the skid aperture and stylus after measurement, preventing adherence and maintaining measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If measurement is performed on machined work with foreign substances adhering to the surface, then measurement can be conducted on real working conditions, but foreign substances enter the gap between skid aperture and stylus causing measurement performance to decline
Solution Approach 1:
The suction device performs preliminary cleaning action by removing foreign substances from the gap between the skid aperture and stylus before measurement begins. This preventive cleaning ensures that foreign substances do not interfere with the measurement process, thus maintaining measurement precision while allowing measurement on machined work with adhering substances.
Solution Approach 2:
The suction device extracts foreign substances from the critical gap area between the skid aperture and stylus. By removing these harmful foreign substances from the measurement zone, the system maintains measurement accuracy while continuing to measure workpieces that have foreign substances on their surfaces.
2Object-generated harmful factors
If compressed air is used to blow foreign substances out of the roughness tester, then foreign substances can be removed, but foreign substances may re-enter the gap between skid aperture and stylus
Solution Approach 1:
The suction device uses pneumatic principles to create negative pressure that actively draws foreign substances out of the gap between the skid aperture and stylus. This controlled pneumatic removal is more reliable than compressed air blowing, as it prevents foreign substances from being blown back into the measurement zone, thus maintaining measurement performance stability.
3Device complexity
If foreign substances are not removed from the gap between skid aperture and stylus, then device structure remains simple, but measurement performance declines due to foreign substance adherence
Solution Approach 1:
The suction device is configured to automatically clean the gap area during or after the measurement process. This self-service cleaning function maintains measurement precision without requiring complex manual intervention or additional complex cleaning mechanisms, as the system performs its own maintenance function.
