"Repeatable,
repeatable, repeatable"; three words that robots
love to hear. With a Demmeler system in front of the robot,
every part coming out of the fixture will be exactly like
the one before. Bores in the Demmeler system are held
+/- 0.001" positional accuracy. Optional hardening
eliminates any risk of spatter build up.
Recipe
for successful robot fixturing: Take one 40" x 80"
table, mount in front of robot with head and tailstock
support and build fixtures as needed. This robot is able
to weld short run jobs (5 pieces to 500 piece runs) four
times faster than a man and with the exact same quality,
part after part.
With
some weldments it is too difficult to fixture all
the loose pieces on a robot. In these cases, a manual,
pre-tack station can be used. The welder simply
sets up a fixture on the Demmeler welding table
outside of the robot cell. While the robot is welding,
the welder can prepare the next load of parts. Bottom
line: no downtime for the robot.
The Demmeler
D16 system offers a lightweight version of the original
Demmeler D28, ideal for applications where weight limitations
exist. This ladder manufacturer has set up a table on
the head and on the tailstock using long, U-form spacer
blocks to join them. The fixturing components (angles,
stops, blocks, clamps) are then attached along the U-form
blocks where needed.
