Unilock Modular Workholding System Vol. 2

AUTOMATION CHUCKS OVERVIEW

Minimizes or Eliminates Flats and Recesses on the Mating Surfaces Where Chips Can Collect and Interfere with the Positioning and Clamping Process The clamping chuck has a ground cone projecting out of its base that is used to establish centerline. Chips and debris will tend to slide off of this surface. Elevation is controlled with small raised pads surrounding the cone. They reduce the surface area on which debris and chips can contaminate the positioning and clamping process. The clamping ring resides on the bottom of the pallet, a location that is not prone to collecting contamination when it is being stored in the robot or locked in a Unilock chuck. Assists in the Cleaning Process so the Chuck Can be Safely Installed in an Automated Cell When the chuck is in an open position (Fig. 1), an upward air blast is activated. These air passages project onto the bottom of the clamping ring to assist in the cleaning process. As the pallet nears its final position, the restriction of the upward air flow is redirected onto the contact surface (Fig. 2). Provides Feedback to the Cell Controller on Clamping Status The air passages are restricted once the pallet is clamped. This restriction can be measured and used to verify pallet presence.
