Sprocket Deburring
JOB NO. 311
MULTI-STATION SPROCKET DEBURRING
Application
A manufacturer of fuel pump components needed a deburring solution for an extremely high-volume part. A number of ops were needed to be done in a limited cycle time and footprint. A coolant system was required to aid the cutting process/machine cleanliness along with a custom front panel assembly for an eventual robot loader. Safety implementations were required to account for a potential operator load.
Solution
Machine Bases
- In order to process high quantities with multiple ops in a small footprint, a medium sized rectangular base is used. A clearance at the machine’s roof allows for a 2” index shaft to move work spindles from op to op.
- 3/8”-1/2” steel plate walls must be used to support any heavier assemblies that will be under pressure/performing deburring ops.
- The wet application’s base must be welded water-tight
Processing
- Work pieces are loaded onto one of four part drive spindles via robot or operator. Drive spindles use pneumatic collet assemblies to clamp work pieces and are installed to a 1” thick ground aluminum dial plate. A 2” shaft is driven by a four-station CAMCO indexer located on the machine’s roof. The indexer assembly allows each spindle to dwell at all work/load stations with excellent repeatability.
- Spindles are independently driven at each cut station by a cushioned drive gear assembly. This gear is directly driven by a high torque A/C motor and is always engaged, meeting the corresponding gear on each spindle as it is indexed in place.
- Once the load spindle has clamped a fresh work piece, it is indexed to three separate work stations consisting of a variation of nylon abrasive cup, disc and radial brushes. Each brush is directly-driven by a large frame wash duty D/C motor. Linear rail and actuator assemblies use Auto Amp Compensation parameters to feed/retract brush positions.
- Adjustable nozzles spray a steady stream of coolant directly onto the work surface while brushing occurs at each station.
Safety/On Site Requirements
- A custom front panel assembly is used to accommodate robotic loading. Panel opening keeps coolant mist inside the work area while allowing spindles to be presented to the robot loader. A custom fin assembly installed to the dial plat further guards the outside environment from machine debris/byproducts.
- Coolant piping and nozzles routed to the work area can be used to aid in cutting, for wash-down of critical components or both. In most wet applications, a sprayer system is also used at the machine floor to wash debris toward the filtration system along with a manual wash down for PM. Cleanliness implementations such as magnetic separation, oil skimming and bag filtration are available upon request.
- Light curtain system has been provided in the event of operator loading. If the space between these posts is breached, the machine will not cycle.
