Abstract:
A shock protection device for protecting a position measuring probe comprising:an outer shell; an inner shell for supporting said position measuring probe, said inner shell being movably disposed within said outer shell to allow relative displacement of said inner shell relative to said outer shell when said shock protection device is in an operating state; at least one shock-absorbing means disposed between said outer shell and said inner shell for absorbing shock exerted on said outer shell thereby protecting said position measuring probe supported on said inner shell against shock exerted on said outer shell when said shock protection device is in an operative state; and at least one engagement means for engaging said inner shell to said outer shell to thereby establish precise positioning of said inner shell relative to said outer shell when said shock protection device is in an inoperative state, wherein said position measuring probe measures at least one of an absolute position and a relative position of an object with respect to a fixed coordinate system.
