Automatic Drilling and Inspection
This machine automatically feeds, separates, drills nine holes and visually inspects automatic clutch hubs in less than 13 seconds.

Accessibility to The Drill Tooling
Although the machine is thoroughly guarded, the drill tooling is easily accessible by removing two hand knobs and opening the door. The automatic escapement and loading mechanisms are mounted to the door and never have to be moved or adjusted after a tooling change.

Part Fixturing
The part shown in the fixture is automatically staged and loaded into the drill fixture. Then 9 radially positioned drill heads simultaneously drill holes while coolant floods the drilling chamber. When the drilling is completed, the part is automatically unloaded from the fixture and loaded into the vision inspection station for verification that all holes were drilled or that no broken drill bits remain in the part.


Test Machine
This machine performs accelerated reliability testing for consumer products based on ANSI criteria for the industry. Itís capable of running in two test modes, a higher force cycling pull test and a higher frequency, lower force, oscillating load test.


Test Fixturing
The pneumatic test cylinders are outfitted with electronic sensors and load cells to assure test accuracy. All air hoses and sensor wiring connections are color coded to facilitate proper setup. All portable fixtures are equipped with wheels and handles to facilitate their movement and setup.


Part Manipulation

Parts enter in two lanes from different presses.  They are grasped, inverted and then lowered onto the line for further processing.

Lane Diverting

Parts enter in two lanes and exit in six lanes via two sets of PLC controlled pneumatic gates.


Measure and Straighten

This machine automatically performs quality checks for length and runout on drive shaft tubes.  Two attempts to straighten a bad tube are performed before the part is determined as a reject.


Hydraulic Ram with Position Feedback

The runout checking and straightening station is comprised of a hydraulic ram with a linear transducer to control the ram position, a servo motor to precisely rotate and position the tube, an LVDT measurement probe to accurately measure the amount of tube runout, and press blocks that lift the tube and lock into position during the straightening process.


Transfer Mechanism

Tubing progresses from station to station by use of a walking beam.  It adjusts in width from 500-1500 mm. The automatic length gauge is positioned in the foreground above the walking beam.



Automatic Furnace Loading

This system is a key continuous improvement element in a J.I.T. production operation.  The loading machine serves as a staging platform and works seamlessly with a 6-axis robot to stack, place in lanes and load parts onto a continuously moving furnace belt. 


Loading Sequence

The robot places parts on the furnace loading machine in various configurations of lanes and stack heights.  When it is finished placing parts, it signals the loading machine to begin loading.  The parts are then pushed onto an elevator and lowered to the furnace beltís elevation.  The elevator retracts from underneath the  parts and gently places them onto the moving furnace belt  while maintaining lane and stack integrity.  During the furnace loading cycle, the robot is signaled to begin loading the next group of parts on the platform to maximize the furnace loading rate.



Installed Grinding Automation

This is a portion of a specially designed automation system used to separate precision ground parts from manufacturing fixtures that are used in the process.  The parts, with fixtures, are automatically regulated through the system, elevated, and separated from each other. The parts are routed on overhead conveyors for downstream processes and the manufacturing fixtures are returned to the front of the grinder for reuse.

Internal View of Elevator

This is an internal view of the elevator.  It raises the part and fixture assembly to a height of about 9 feet for accessing downstream operations.  It has the capability of handling part and fixture combinations from 6Ē diameter to 11Ē diameter and from 1/4" thick to 1" thick.  It is powered by a variable frequency drive that allows adjustment of the elevating speed to match the output of the double disk grinder for the various products running through it.



System Controls

Variable frequency drive controllers.  Touch screen operator interface panel.  Heat exchanger for cabinet cooling.


Operator Interface Panels

Remotely controlled by PLC's.  Operator interface panels are typically located near an operator's work station and allows  the machine attendant to navigate through screens on the touch panel to control, monitor, and perform machine diagnostics.
