Multiple-blade holding devices

Abstract

An exemplary device includes first and second portions that are movably connected together by first and second sets, respectively, of multiple blades interleaved with each other at an overlap region. When the overlap region is compressed, displacement of the first and second portions relative to each other is prevented so as to provide relatively high stiffness in first and second orthogonal directions (e.g., z- and y-directions) and relatively low stiffness in a third orthogonal direction (e.g., x-direction). The device can be used in coordination with an actuator, wherein operation of the actuator and compression of the overlap region are automated.

Description

technical field [0001] In particular, the invention relates to a device for holding and / or supporting an object in a desired position in three-dimensional space. [0002] This case claims priority to U.S. Provisional Application No. 61 / 498,935 filed on June 20, 2011, and U.S. Patent Application No. 13 / 527,206 filed on June 19, 2012, the contents of which are hereby incorporated by reference. Background technique [0003] The need to maintain one object relative to another is common in the industry. For example, if the workpiece is not held rigidly and accurately, it is often very difficult or impossible to perform accurate and precise movements on or relative to the workpiece. Robots rely extensively on their ability to hold a tool or other processing implement relative to a workpiece, hold a workpiece relative to the implement, or both. In precision systems, the requirements for holding devices are particularly stringent. [0004] This exemplified precision system is a ...

Finally, since using bolts and washers in this way can provide pH stability relative to PT down to the micron range, it is very difficult to adjust

[0006] Thus, conventional devices and methods for holding a first object (e.g., PH or similar component) relative to a second object (e.g., PT or similar component) fail to address the need to provide stiffness in both a vertical direction and a horizontal direction, Flexibility in another horizontal direction, strength and stability under load, ease of adjustment, accuracy of adjustment of the height and angle of the held object, and use with movers or actuators to operably change in three-dimensional space A combination of the ability to maintain object positions in
