The manual piston measurement system of automobile manufacturers is slow, cumbersome, and cannot guarantee quality during final inspection measurement. So they need better measurement methods to detect pistons, so that they can sort qualified pistons, and improve the manufacturing process through statistical data of measurement results.

Edmunds has developed a multi station automatic measurement system placed in the processing area——Piston comprehensive measuring instrumentThe basic working method is that after the outer circle and pin hole of a piston are processed, it is transferred to another area where a certain piston is selected and placed into the measurement system. The * station is for chip removal, and the equipment at that station is three sliding steel hooks. As the workpiece rotates, iron filings are removed from the annular groove. The second workstation is a cleaning and drying system. At the cleaning workstation, the piston is placed in a cleaning tank with cleaning nozzles (consisting of an outer circular nozzle and an inner hole nozzle), where residual coolant is removed. Additionally, there is an air pump connected to the nozzle. A recyclable lid covers the cleaning tank to prevent the cleaning solution from splashing outside. The drying station is a similar design, where a nozzle blows compressed air and a vacuum cleaner removes water droplets from the surface of the piston to dry it.
The next operation is eddy current crack detection, where the workpiece rotates once for inspection. If cracks no larger than 0.005 inches are detected in the diameter of the piston head and edge, the piston is moved to the pin hole positioning area, where the laser reflection determines whether the piston is qualified (through the position of the pin hole). If it fails, the programmable controller controls the piston to rotate 180 degrees and controls the piston to rotate to the correct position for measurement.
Then, the piston is placed on a stick to polish its surface. Starting from here, measure the diameters of the three skirts of the piston using differential measurement method. The pin holes are measured at four positions, and the height of the combustion chamber and the offset of the pin holes are also measured.
All measurement data (qualified or unqualified) are stored in the computer-aided measurement system. The piston is placed on the balance for weighing, graded, and printed with grading labels. Next, using a computer-aided measurement system, pistons are grouped into qualified and unqualified ones. Qualified pistons exit the measurement system, while unqualified ones are placed on the slide leading to the unqualified products. The function of the piston comprehensive measuring instrument is to ensure that the packed piston is a qualified product. And the computer-aided measurement system can analyze statistical data, adjust the processing process, and ultimately reduce the product's failure rate.
