TORCH WIZARD INSTALLATION & OPERATION MANUAL
2.5 REAMER ADJUSTMENT
In order to ensure adequate cleaning of the gas nozzle, it is
essential that the correct reamer insertion depth is obtained.
The reamer insertion depth will vary based upon the nozzle, tip
and diffuser on the torch. In general, the reamer can be inserted up
until it is approximately 1/16" to 1/8" away from making contact
with the diffuser (see example in Fig. 6b). Removing the nozzle
from the torch to ensure the proper depth and clearance from the
diffuser is recommended.
It is imperative that the reamer not
make contact with the gas diffuser as this will cause damage to
both the reamer and the gas diffuser. The Torch Wizard® is not
designed to clean the contact tip or gas diffuser.
To adjust the reamer depth, use the following procedure and refer
to Fig. 6a:
(Ensure that there is no air pressure or electrical
power to the unit before performing this procedure).
1. Remove the Stainless Steel Guard (refer to Fig. 4 and the
procedure for adjusting the V-Block o
n page 5)
.
2. With one hand, hold a gas nozzle in the V-Block at the position
that will be used when programming the robot. With the other
hand, raise the reamer and check the insertion depth of the
reamer bit (1).
3. If the insertion depth is incorrect, loosen the Socket Head Cap
Screws (2). Move the Air Motor (3) up or down to obtain the
correct insertion depth. If the motor will not move, screw in the
Jack Screws (4) to loosen the motor clamp.
4. Back out the Jack Screws (4) if necessary, and tighten the
Socket Head Cap Screws (2). Repeat steps 1 – 3 until the correct
insertion depth is obtained.
Note:
The air motor on this reaming station has a max torque of
7.3 ft/lbs @ 90 psi at the motor.
Positioning Robot
The robot
must
be positioned such that the O.D. of the nozzle rests evenly against the V-Block. Failure to program the
robot so that the nozzle rests against the V-Block could result damage to the robot due to reactionary forces transmitted
to the robot axes when the nozzle is clamped with the air cylinder.
See page 12 for the electrical schematic for your Torch Wizard® model.
WARNING:
Ensure that the adjustable V-Block and the air motor have been correctly set prior to positioning the robot
and running the Torch Wizard® in the automatic mode. Refer to sections
2.4 Adjusting V-Block and 2.5 Reamer Adjustment
.
Failure to adjust these two items properly will result in damage to Torch Wizard® and possibly the robot.
