Mounting the Telescopic Axis on Robots with a Rotational Axis

  DANGER
ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
  • Disconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires except under the specific conditions specified in the appropriate hardware guide for this equipment.
  • Always use a properly rated voltage sensing device to confirm the power is off where and when indicated.
  • Operate electrical components only with a connected protective ground (earth) cable.
  • Verify the secure connection of the protective ground (earth) cable to all electrical devices to ensure that connection complies with the connection diagram.
  • Do not touch the electrical connection points of the components when the module is energized.
  • Provide protection against indirect contact.
  • Insulate any unused conductors on both ends of the motor cable.
Failure to follow these instructions will result in death or serious injury.
NOTICE
INSUFFICIENT PART CLEARANCE
Ensure that the universal joint does not touch the gearbox seal during assembly.
Failure to follow these instructions can result in equipment damage.

Step

Action

1

Extend the telescopic axis to its entire length, then retract the same and verify its resistance.

NOTE: A light irregular resistance is normal and caused by the manufacturing tolerances of the tubes. The axis is run in during the first 100 hours of operation.

2

Loosen the clamping screw (1) at the top universal joint.

3

Remove the three countersunk screws (2) from the underside of the bottom universal joint.

4

Place the parallel plate on the bottom universal joint as shown in the following figure and ensure that the locating pin (3) is in alignment with the corresponding hole of the parallel plate (4).

NOTE: In the delivery condition, the index pin is located in the universal joint of the telescopic axis. During dismounting, it may be located in the parallel plate.

5

Attach the parallel plate to the universal joint by using the three countersunk screws that were removed previously. Use the high strength retaining compound Loctite 648 for this purpose.

Tightening torque: 1 Nm (8.9 lbf-in)

NOTE: Apply the high strength retaining compound Loctite 648 into the tapped holes as opposed to applying it to the screws.

6

Push the universal joint (6) over the shaft (7) protruding from the robot housing until the universal joint comes into its stop position on the gear shaft flange. In doing so, rotate the universal joint to ensure that the recess in the universal joint is located above the keyway (5).

7

Tighten the clamping screw (1) that was loosened previously.

Tightening torque: 7.4 Nm (65 lbf-in)
