Abstract
A member having an axis to be positioned in an opening whose axis may be displaced from the member axis is connected by three rods, wires or wire ropes equally spaced about the axis secured to a supporting plate and having a first portion generally perpendicular to the plate and a second portion extending downwardly from the first portion with the lower end closer to the member axis than the upper end with the first portions allowing translation of the member and the second portion allowing rotation of the member to enable the member to be aligned in the opening as the upper support member moves downward toward the opening. The rods, wires or wire ropes may be separated by a spreader and reside within an elastic body with damping and be preloaded in tension or compression.
Claims12
A remote axis admittance system comprising,
- a first support means for receiving an actuating force,
- compliance means secured to said first support means and having a first portion defining a translation region and a second portion defining a rotation region,
- said first and second portions being contiguous,
- a second support means coupled to said first support means by said compliance means for supporting part gripping means,
- and part gripping means carried by said second support member,
- said translation region responding to a force developed about a compliance center or axis embraced by said part gripping means by deflecting in a direction producing translation of said part gripping means and said rotation region responding to a moment by producing rotation about said compliance center or axis.
