Positioning Stage Provides Two Axes of Coordinated Motion

Sept. 8, 2017
Customer cables can be routed within the cable carriers on H2W Technologies' latest stage.

The single rail positioning stage H-gantry design is an open frame XY positioning system.  It has two bottom parallel axes with one cross axis connecting the two (H-gantry).

 

Each linear axis uses brushless linear motors (BLDM-B04), and each has a total stroke length of 25.67 in.; can generate 6.2 lb. of continuous force and 18.7 lb. of peak force, or a combined 12.4 lb. continuous force and 37.4 lb. of peak force on the bottom axis.  The non-contact 1-micron resolution encoders allow for precise positioning.  The moving tables are guided by a precision recirculating linear ball bearing system. 

 

The linear axes are assembled on a single piece of aluminum extrusion, thus reducing the overall weight of the system.  The top cross axis is mounted to the bottom parallel axis using rigid aluminum extrusions, 90-deg. right angle gussets, and custom extrusion end plates.  The system is mounted to a flat aluminum tooling plate base.  There are also provisions that allow customer cables to be routed within the cable carriers.  It has end-of-travel rubber bumper stops.

 

Additional options include, a home positioning sensor, end-of-travel-sensors, and custom mounting holes.  Single extrusion length of up to 6 m long, allows for longer stroke applications.

Features:

  • low system weight
  • built using standard extrusion profiles
  • cable carriers to route payload cables
  • three axis of coordinated motion
