AFD52 Adjustable Force Device Manual rushCorp. Inc. Dallas, Texas

HANDLE WITH CARE DO NOT DROP DO NOT USE LUBRICATED AIR. This device requires a dry, non-lubricated 80 psi (5.5 bar) maximum air supply filtered to 5 pm and a 0.3 micron oil mist separator. Non-compliance with these requirements will void the manufacturer’s warranty. (See Section 3.4) All fasteners, mounting holes and pipe threads on this tool are METRIC. All PushCorp, Inc. electrical cables are rated for high twist and flex robotic applications with a minimum cable bending radius specification of 125mm (5 in). Cable damage resulting from failure to abide by this specification will not be...

Purchasers requiring...

2.0 General Overview The PushCorp, AFD52 Passive Micro AFD is designed for low force applications on small capacity robots. As such, the AFD52 is simple and light weight, but it still incorporates several innovative features. The AFD52 uses glass pneumatic cylinders with graphite pistons, and linear ball bearings to reduce operating friction and increase force accuracy. It can be configured to mount on many low capacity robots. The Micro AFD may also be supplied to apply only a positive force, the AFD51, or both positive and negative forces, the AFD52. The AFD52 requires the user to supply...

3.0 Installation 3.1 Mounting Process Equipment The AFD52 Adjustable Force Device can accommodate different process equipment and configurations. Examples of two mounting configurations are shown in Figure 1. The tooling can be oriented parallel or perpendicular to the Carriage axis of translation, although it is important to note that the AFD can apply force only in the direction of Carriage translation. When mounting to the Carriage care should be taken. An incorrectly designed process equipment mounting bracket can deform the Carriage causing internal Linear Rail misalignment. A symptom...

3.2 Mounting the AFD52 The basic configuration of the AFD52 force device allows attachment to a stationary fixture or a manipulator mounting flange. There are three mounting options for the AFD, these are shown in Figure 3. Figure 3. AFD52 Mounting Options Options 2 and 3 are supplied with two mounting plates as shown in Figure 4. Two mounting plates are required if the standard mounting option 1 does not allow sufficient clearance. To attach the AFD52 to a manipulator mounting flange using options 2 or 3: First, attach the Robot Mounting Plate to the robot; second, attach the AFD Plate to...

Figure 4. Mounting Sequence Option 2 or 3 CAUTION: The Fastener Tightening Torque Specs chart in Section 6.0 should be used to determine proper fastener length and torque. This is to prevent pull-out of the helicoil inserts. 3.3 Maximum Carriage Load Calculations The Linear Rail bearings that support the AFD52 Carriage have been selected to provide optimal performance with respect to capacity, size, and low friction. To ensure continued optimal performance it is very important not to overload these bearings. The following diagrams and associated equations allow your application to be...

3.4 Pneumatic Supply The AFD52 Adjustable Force Devices require a dry, non-lubricated, 5 m filtered, 80 psi (5.5 Bar) maximum air supply. Failure to provide supply air to these specifications can degrade performance and will void any warranty repairs concerning pneumatic components. Filtered air is required to prevent foreign material from entering the AFD. The pneumatic supply system should be configured as shown in the Figure 6. Figure 6. Pneumatic configuration If water condensation is a problem in your air supply system, an air dryer device is highly recommended. The ideal solution is...

Figure 7. AFD52 air connections The Supply Line and Purge Line to the device should be 6 mm or 1/4 inch diameter flexible polyurethane tubing. The tubing should be routed to the AFD such that there are no kinks and that there is plenty of slack to allow for manipulator motion. Before inserting the Supply Line or Purge Line into the air fitting, open the supply valve to blow out any contaminates which may be in the tubing. The tubing can now be pushed into the self-locking fitting located on the top of the AFD. Charge the Supply Line with compressed air and verify that there are no air leaks...

4.0 Adjusting Carriage Preload The required preload on the AFD52 Carriage Linear Rails has been set at the factory for optimal performance and, in general, should not require adjustment. Normally the Carriage will only require adjustment after removal for service. Should the Carriage require adjustment contact PushCorp, Inc. or return the AFD for re-adjustment. 5.0 Achieving Desired Force The AFD52 is a passive force device that requires the user to provide pressure to the pneumatic actuator. Pressure in the actuator results in an output force at the Carriage. If the AFD is always in the...
