AFD52

Active Compliance Force Device

The PushCorp AFD52 Series Passive Force Device is a simple, low-cost wrist mounted unit for light weight deburring, knife trimming or surface finishing applications. Using a low friction cylinder and linear rail technology this device delivers outstanding performance.  Fitted with a high speed motor the AFD52 Series excels at deburring work, whether removing parting lines or chamfering an edge. Mount a small grinding or polishing motor and perform light surface finishing.

The 52 Series can be configured as either an AFD51 single acting with only positive force application, or an AFD52 double acting with positive and negative force capability.

Here are just a few operations the AFD52 Series, matched with the proper process equipment, can accomplish faster, more accurately, and with greater control than ever before:

  • Grinding (molds, weld beads)
  • Deburring (parting lines, chamfer)
  • Polishing (glass, wood, sheet metal)
  • Drilling/Chamfering (thru-hole, to-depth)
  • Weld Shaving
  • Any other process which requires an accurate, compliant, continuously adjustable applied force.

The PushCorp AFD52 Series Passive Force Device was designed for low force applications on small capacity robots. As such, the AFD52 Series is very simple and light weight, but it still incorporates several innovative features. The AFD52 Series uses glass pneumatic cylinders with graphite pistons, and linear ball bearings to reduce operating friction. It can be configured to mount on many low capacity robots. The AFD52 Series may also be supplied to apply only positive forces, the AFD51, or both positive and negative forces, the AFD52.

The AFD52 Series requires the user to supply at least one pressure regulator to control the force output.

If an AFD52 is specified then two regulators are required. The device has low friction components, so that the force output resoulution is highly dependant on the regulator accuracy. The regulator can be manual or electrically controlled based on the application. If a constant force is required and the tool orientation does not change a manual regulator is sufficient. If the force and/or orientation changes during the process, then an electrically controlled regulator is required. This means that the process equipment weight must be compensated for, which requires calculation of the regulator pressure.
