【発明の名称】座標測定機の探査ヘッド
Document Type and Number:
Japanese Patent JP2557955
Kind Code:
B2
Abstract:
A feeler head for coordinate measuring machines has a torsionally stiff, zero-backlash and frictionless spring system which defines a spatial coordinate system and carries a feeler that can be displaced in all three spatial directions. In order to be able to use the feeler head completely independently of position, it is possible for each of the three space axes to switch into the associated spring system a balancing device which automatically sets the zero position of the spring system in each spatial position of the feeler head. In this case, it is particularly advantageous to construct each balancing device from two springs which act in different directions on an element that is deflected by forces due to weight in the event of a change in spatial position. The spring force of at least one of these springs can be set in order to achieve the zero position detected by an indicator, that is to say the balancing.
