2.0 General Overview
The PushCorp, Inc. 1240 Series Adjustable Force Device (US Patent No. ,448,146)
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 1.4 in. (36 mm) of
compliant stroke. The AFD is designed to withstand continuous use in harsh
industrial grinding, polishing, and drilling operations.
The 1240 Series compliant tools utilize a pneumatic actuator to provide the force
and provide closed-loop feedback. The 1240 Series can apply up to a maximum
269.8 lbs. (1200 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 1240 Series is filtered,
non-lubricated, 80 - 90 psi ( . – 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 1240 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 1240 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 1240 Series.
Step 1: Carefully unpack the 1240 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 1240 Series Mounting Bracket to the manipulator
mounting flange or support table per Section 4.2.
Step 3: Connect a dry, non-lubricated, m filtered 80 to 90 psi ( . to 6.9 bar)
air supply to the 1240 Series per Section 4.3.
Step 4: 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 1240 Series Adjustable Force Device.

4.0 Installation
4.1 Mounting Process Equipment
The 1240 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 Rails and effect the consistency of 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

PUSHCORP, INC. AFD1240 Manual
The bolt pattern on the Carriage has been designed to facilitate process equipment
installation. The Carriage has (34) thirty-four M8x1.2 mounting holes with a depth
of 0.47 inch (12 mm) to provide secure attachment points. The mounting holes are
spaced 8 inches (127 mm) across and on 2 inch (2 .4 mm) centers along the length
of the Carriage. (See Figure 1) The Carriage also has (4) four mm 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 Rails.
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 1240 Series
The basic configuration of the 1240 Series force device allows attachment to a
stationary fixture or a robotic manipulator mounting flange. Specifying an AFD1240
-1 or -2 determines which Mounting Bracket is supplied. Adapter plates or "quick-
change" attachments can be used as well for mounting. The 1240 Series has (2)
two 4mm dowel pins pressed into the base for location and alignment of the cover
and Mounting Brackets.
4.2.1 Mounting the AFD1240-1 Vertical and AFD1240-2 Horizontal
The AFD1240-1 and AFD1240-2 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 1240 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.
