Project Detail 

A bowl feeder with a vibratory inline conveyor queues the valve stems and positions the parts.  A rotary table with eight (8) positions indexes the stems from station to station.  The table will be divided into a dry zone, and a wet zone, to contain chips and coolant, and keep the components in the dry zone as clean and dry as possible.  At the inline conveyor, in the dry zone, the table will index and grip the part with a gripper while aligning a flat on the stem for proper drill alignment.  The drill stations will use standard length drill bits that will be placed in the collet and bottomed out so that the operator will not have to re-gauge each bit.  

The first index will take the part into the wet zone, and stop at the first drilling station.  The drill will automatically feed the drill.  The coolant will be misted onto the drill using an Acculube misting lubricator.  Once the drilling operation is complete the table cycles again and brings the part to the second drill where the optional second hole will be drilled.  The operator will be able to select single or dual-hole drilling modes from the HMI.  After drilling the part the machine indexes to a blow off station.  This station will remove any chips and coolant left on the part after drilling to provide the most accurate vision inspection.   Then the part indexes into the dry zone once again.

Drill bit breakage detection is accomplished with a mechanical wisker sensor at each drill head.  The camera station detects out of tolerance or missing holes with a tolerance of +/- 0.001".  This machine meets or exceeds a C_pk of 1.66 and has run 12-14 million parts.

The following video shows the camera inspection screen where we are looking at two different part inspections.  First the hole locations are inspected, and then the part is inspected for chips or debris in the main through hole.  The video then shows a shot of the HMI where all part data is displayed.  Finally, it shows detail of the operation of the machine.  Please Contact Us for more information or help with your application.
