Piston pins are one of the critical parts of engine, which withstand high loads and stress when an automobile is on the road. As a results, inspection of piston pin are especially important for preventing piston pin from breaking. This inspections are during production in the continues operation and include detecting surface defects, monitoring microstructural properties, including hardness, case depth, and so on,
Eddy wise offers two following solutions, namely EddyDesk and EddyAuto for the inspection of piston pin.
EddyDesk is a desktop solution for detecting surface defects at the laboratory. This is made by integration of mechanical handling together with EddyLine I eddy current testing system. Accordingly, EddyDesk can detect any transverse, longitudinal, point defect, and any missing material caused by the production process on the exterior shell of piston pin or any cylindrical object with external diameter from 5 mm to 200 mm. For this device, the test pieces are loaded by a user. Then, they will be inspected and the result can be documented for further use, shown on the EddyLine I screen, and sorted into good and bad parts. Documentation can help piston pin manufacturer to analysis and improve their production process. Consequently, EddyWise helps manufacture to increase their quality requirements and ppm.
EddyAuto is an automated 100% crack detection standing machine used during production in continues operation. It works with EddyLine II and rotary solution. Rotary solution fully scan the entire external shell of piston pin by helical movement. EddyAuto can detect any transverse, longitudinal, and point defect on the exterior shell of piston pin or any cylindrical object with external diameter from 5 mm to 200 mm.
Piston pin parts are, loaded into the EddyAuto, and sorted, automatically, into good and bad group based on the inspection of their outer shell surface. The result will be documented for the future use, and finally, helps manufacturer to improve the quality of their production product.
Beside, EddyAuto has an optional channel to check microstructural structure of piston pin; including the correct heat treatment, case depth, and hardness with an Specific Encircling coil.
The speed of inspection can be adapted to the production requirement of manufacturer. This system can be installed directly at the downstream of the last grinding operation as stand unit and integrated directly on the existing conveyor; accordingly, rendering the inspection station extremely compact and easy to maintain.
EddyWise designed EddyAuto to solve of the problem of piston pin inspection as much as possible without need of particular work piece handling to reduce the production cost sufficiently.
