2.0 General Overview The PushCorp, 70 Series Passive AFD was designed as a low cost alternative to the 1000 Series Active Force Device. As such the 70 Series is a more basic unit that still incorporates several innovative features. To reduce operating friction and increase force accuracy the 70 Series uses glass pneumatic cylinders with graphite pistons, and linear ball bearings. The AFD72 incorporates an internal linear potentiometer that allows the monitoring of the Carriage position during operation. It has two robot mounting configurations, and a table top mounting configuration. The...

your process. The Carriage preload is correctly set at the factory and should not require adjustment. If the Carriage becomes loose or binds after installing the process equipment, then the brackets must be removed and the problem corrected. PushCorp, Inc. can design and fabricate brackets to user supplied specifications as an option. Figure 1. Carriage bolt hole pattern The bolt pattern on the Carriage has been designed to facilitate process equipment installation. The Carriage has (16) sixteen M6x1 mounting holes with a depth of 0.40 inch (10 mm) to provide secure attachment points. The...

3.2.1 Mounting the AFD70-1 Vertical and AFD70-2 Horizontal The AFD70-1 and AFD70-2 are supplied with a standard Mounting Bracket shown in Figure 2. A minimum of (3) three holes should be utilized to secure the Mounting Bracket to the robot mounting flange. Figure 2. AFD70-1 and AFD70-2 Mounting Brackets

If the Mounting Bracket is supplied blank or additional holes are required, it must first be removed from the device before drilling. (4) Four M6x1 Socket Head Cap Screws are used to attach the Mounting Bracket to the AFD72 force devices. Once the Mounting Bracket is removed, mounting holes may be placed anywhere within the crosshatched area shown in Figure 2. PushCorp, Inc. will supply engineering support to determine the mounting hole locations at no cost. After drilling the required hole pattern, remove any burrs and clean any machining residue from the Mounting Bracket. The Mounting...

weight and force loads must be less than the Bearing Load (L). If the AFD72 is placed in multiple orientations, then the Bearing Load (L) should be checked for each one. If your application is not similar to any of the designs listed here, or if the information is not clear, please contact PushCorp Technical Support for assistance. Ball-bearing equations apply to the standard AFD72. Roller-bearing equations apply to AFD72 ordered with the –HD, Heavy-Duty option.

3.4 Pneumatic Connection The AFD72 Adjustable Force Devices require a dry, non-lubricated, 5 µm 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 Figure 4. Figure 4. Pneumatic configuration To apply force in the positive + direction, on an AFD71 or AFD72, a Supply Line must be connected to the + Supply Air Port. To...

If water condensation is a problem in your air supply system, an air dryer device is highly recommended. The ideal solution is an industrial chiller dryer capable of reducing the dewpoint to less than 32 F (0C). Moisture inside the AFD will cause premature failure that will not be covered under warranty. In applications where the environment contains suspended particulate matter purge air flow must be used to ensure that the inside of the AFD remains clear of foreign matter. A Purge Port on the AFD72 (See Figure 5.) provides a pneumatic connection to supply this air flow. The port accepts...

4.0 Adjusting Carriage Preload The preload on the AFD72 Linear Rails has been set at the factory for optimal performance and, in general, should not require field adjustment. However, there are situations that could arise that cause the Linear Rails to need adjustment. NOTE: Any tampering with the Preload Adjustment Set Screws will void the factory calibration. Often a loose, or tight, Carriage on a new AFD is indicative of an improperly designed process equipment bracket. If the problem disappears when the brackets are removed then this is the case. Normally the Carriage will only require...
