2.0 General Overview
The PushCorp, Inc. 620 Series Adjustable Force Device (US Patent No. 5, 8,1 6)
provides a superior force application system for robots and other automated
equipment. The device can be placed in any position to enable a variety of
manufacturing operations requiring a consistent applied force with 1.6 in. ( 0 mm) of
compliant stroke. The AFD is designed to withstand continuous use in harsh
industrial grinding, polishing, and drilling operations.
The 620 Series compliant tools utilize a pneumatic actuator to provide the force and
provide closed-loop feedback. The 620 Series can apply up to a maximum 115 lbs.
(512 N) of force. The AFD contains an accelerometer that monitors orientation and
allows the unit to automatically compensate for gravitational and inertial effects. A
linear potentiometer is also present within the AFD to sense the position of the
Carriage.
The only external connection that is required to operate the 620 Series is filtered,
non-lubricated, 80 - 90 psi (5.5 – 6.2 bar) supply air provided through flexible tubing.
An optional Purge Port is also provided for applications where great amounts of fine
dust particles are created. The Purge Port connection provides additional airflow
and internal positive pressure to help minimize the amount of contamination
infiltrating the interior of the AFD. The AFD’s sliding Carriage has threaded
mounting holes to provide easy process equipment attachment.
All these features combine to make the PushCorp 620 Series Adjustable Force
Device a rugged, state-of-the-art technology capable of providing reliable, precise,
and consistent results in a variety of industrial applications.

3.0 Quick Start
This section contains step-by-step instructions on how to quickly get the 620 Series
Adjustable Force Device up and running for a quick test of its capabilities. Complete
details on all the features are described in the sections that follow. It is
recommended that the user read the entire manual before beginning any operations
to fully understand all the aspects and features of the 620 Series.
Step 1: Carefully unpack the 620 Series Force Device and verify that all parts
indicated on the packing list are present and in good condition. If there
is a problem, please notify the factory immediately so that corrective
action may be promptly initiated.
Step 2: Securely attach the 620 Series Mounting Bracket to the manipulator
mounting flange or support table per Section .2.
Step 3: Connect a dry, non-lubricated, 5 m filtered 80 to 90 psi (5.5 to 6.9 bar)
air supply to the 620 Series per Section .3.
Step : Consult the FCU-FLEX Manual for electrical connections and software
setup information.
Please read the following sections to learn the full potential and features of the
PushCorp 620 Series Adjustable Force Device.

4.0 Installation
4.1 Mounting Process Equipment
The 620 Series Adjustable Force Device can accommodate many different types of
process equipment. PushCorp provides a variety of standard process equipment
such as weld shavers, high speed motors, plus other specialized tooling. Many end
users also develop process equipment for their own applications. The AFD can be
oriented parallel or perpendicular to the robotic manipulator mounting flange,
although it is important to note that the AFD can apply force only in the direction of
Carriage translation.
When mounting process equipment to the Carriage extreme care should be taken
while designing and installing the brackets. Correctly designed brackets will increase
the stiffness of the Carriage by becoming an external superstructure for the
Carriage. The Carriage can gain a tremendous amount of rigidity if this approach is
executed correctly. Incorrectly designed brackets will deform the Carriage surface
causing internal Linear Rail misalignment. A symptom of Carriage deformation is
“slop” or “binding” of the Carriage. A deformed or loose Carriage will damage the
Linear Guides and effect the consistency of your process. 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

PUSHCORP, INC. AFD620 Manual
The bolt pattern on the Carriage has been designed to facilitate process equipment
installation. The Carriage has (1 ) fourteen M8x1.25 mounting holes with a depth of
0.51 inch (13 mm) to provide secure attachment points. The mounting holes are
spaced 6.5 inches (165.1 mm) across and on 1 inch (25. mm) and 2 inch (50.8mm)
centers along the length of the Carriage. (See Figure 1) The Carriage also has (2)
four 5mm dowel pin holes to facilitate alignment. (See Figure 1 for location) These
dowel pin holes are oversized to allow the pins to be glued into place using Loctite
609, or equivalent.
ARNING: DO NOT press pins into the AFD Carriage as this will likely damage
the bearing Linear Guides.
CAUTION: The Fastener Tightening Torque Specs chart in Section 6.0 should
be used to determine proper fastener length and torque for fasteners into the
Carriage. This is to prevent pull-out of the Carriage helicoil inserts.
4.2 Mounting the 620 Series
The basic configuration of the 620 Series force device allows attachment to a
stationary fixture or a robotic manipulator mounting flange. Specifying an AFD620 -1
or -2, or -3 determines which Mounting Bracket is supplied. Adapter plates or
"quick-change" attachments can be used as well for mounting. The 620 Series has
(2) two mm dowel pins pressed into the base for location and alignment of the
cover and Mounting Brackets.
4.2.1 Mounting the AFD620-1 Vertical and AFD620-2 Horizontal
The AFD620-1 and AFD620-2 are supplied with a standard Mounting Bracket with a
90 mm three hole mounting pattern, See Figure 2. All three holes should be utilized
to secure the Mounting Bracket to the robot mounting flange. If the Mounting
Bracket is supplied blank or additional holes are required, it must first be removed
from the device before drilling. Four cap screws are used to attach the Mounting
Bracket to the 620 Series. 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 Bracket can then be reattached.
