Applying Power and Air | Operating the Gage

THE GAGE

The Gage assemble consist of a computer, the gage fixture, and table with associated controls. Please review the unpacking procedures completely. Do not attempt to apply power or air at this time! The gage must be properly unpacked and all materials removed to avoid expensive damage to the load cell sensors.

UNPACKING

! CAUTION ALERT! USE EXTREME CARE TO AVOID DAMAGE TO SENSORS

Before unpacking, please review the procedure as to avoid damaging the sensors. The gage has been packed to protect all the moving assemblies. Do not plug any electrical cords or air to the gage until all the packing materials have been removed and verified.

LOAD CELL SENSORS

! CAUTION ALERT! USE EXTREME CARE TO AVOID DAMAGE TO SENSORS

The load cell sensors are mounted on two assemblies. This picture is of the bottom sensor assembly. The sensor is a rectangular design with a mechanical interlock to help protect from overloading the load cell. An Allen head screw that holds the cell to the plate.

The white plastic probe tips touches the part and transfers the force to the load cell. The white plastic probe tip screws into the body of the load cell. Do not over tighten the tip. Avoid touching the load cell and the white plastic probe tip. Do not let any objects fall into or interfere with the free movement of the load cell.

UNPACKING

! CAUTION ALERT! USE EXTREME CARE TO AVOID DAMAGE TO SENSORS

Most of the packing is labeled and tagged for easy identification. There are 4 main locations where packing exists: The top sensor plate, the bottom sensor plate, the reset pin plate, and the carriage assembly.

Remove the top plexiglass frame of the gage fixture house. There are 4 Allen head bolts that hold the top frame on. The front, back and left side of the gage feature removable plexiglass panels. Remove these panels at this time.

UNPACKING THE CARRIAGE RESTRAINTS

! CAUTION ALERT! USE EXTREME CARE TO AVOID DAMAGE TO SENSORS

Most of the packing is labeled and tagged for easy identification. There are 4 main locations where packing exists: The top sensor plate, the bottom sensor plate, the reset pin plate, and the carriage assembly.

UNPACKING THE RESET PIN PLATE

! CAUTION ALERT! USE EXTREME CARE TO AVOID DAMAGE TO SENSORS

All of the plate assemblies (upper sensor, lower sensor and reset pin) are shipped with springs, foam and rubber insolation. Remove all the foam and rubber insolation. Also remove the 3 Allen head bolts and discard the 3 shock absorbsion springs. Replace the Allen head bolts.

 

RESET PIN ASSEMBLY

The plate that holds the reset pins should look like the picture on the right with all the springs and packing materials removed.

UNPACKING THE BOTTOM SENSOR ASSEMBLY

! CAUTION ALERT! USE EXTREME CARE TO AVOID DAMAGE TO SENSORS

The packing is labeled and tagged for easy identification. Remove all the foam and rubber insolation. Also remove the 3 Allen head bolts and discard the spring shock absorbsion spring. Replace the Allen head bolts and tighten.

 

UNPACKING THE TOP SENSOR ASSEMBLY

! CAUTION ALERT! USE EXTREME CARE TO AVOID DAMAGE TO SENSORS

The packing is labeled and tagged for easy identification. Remove all the foam, cardboard and rubber insolation. The two right pictures show a view from the backside of the gage (top) and the front side of the gage (looking up).

 

 

 

 

 

 

EXTENDED UPPER SENSOR ASSEMBLY

The picture on the left shows the upper assembly extended. With no air pressure, the assemble will slide to this position. When air is applied, the upper sensor assembly will move up to its upper rest position.

VERIFY GAGE OPERATION

! CAUTION ALERT! USE EXTREME CARE TO AVOID DAMAGE TO SENSORS

DO NOT APPLY POWER AT THIS TIME.

Verify the sliding movements of the gage at this time. The carriage can be slide to the left. Note that the lower sensors will clear the carriage assembly. DO NOT PLACE A PART ON THE GAGE AND SLIDE THE CARRIAGE. DOING SO WILL IMPACT THE UPPER LOAD CELL PROBE TIPS AND CAUSE POSSIBLE DAMAGE. Slide the carriage assembly back to the right to its rest position.

Place your hands on either side of the reset pin assembly and lift it with uniform pressure. Carefully lift the rest pin assembly and verify that is moves freely.

Very carefully do the same for the lower plate assembly. Again exercise caution anytime you move a plate manually, when your hands are near the probes, and anytime a part is in the fixture carriage. Verify that the lower sensor assembly will not contact the carriage assembly.

Verify that all the bottom assemblies have had the springs removed. There are no springs used in the gage. All motion is controlled by the application of air in the various cylinders.

Do not force any sliding assembly.
