Coordinate measuring machine with constrained counterweight
First Claim
Patent Images
1. A coordinate measuring machine comprising:
- a motor;
a measuring member;
a counterweight, the motor coupled with the counterweight, the motor rotating a shaft to cause the counterweight to move in one linear dimension;
a pulley and cable system coupling the measuring member with the counterweight; and
a guide track, the counterweight being movably secured to the guide track, the guide track substantially limiting counterweight movement, relative to the motor, to one dimension,wherein the cable system substantially reduces errors from the counterweight to the measuring member.

Abstract
A coordinate measuring machine has a measuring member for measuring a workpiece, a counterweight to control movement of the measuring member, and a pulley and cable system coupling the measuring member with the counterweight. The coordinate measuring machine also has a guide track, where the counterweight is movably secured to the guide track. The guide track substantially limits counterweight movement, relative to the measuring member, to one dimension.

14. A coordinate measuring machine comprising:
-
a motor; a measuring member; a counterweight; a first pulley and cable system coupling the measuring member with the counterweight; a second pulley system coupling the motor to a shaft, the motor and second pulley system thereby configured to move the counterweight by rotating the shaft; and a guide track, the counterweight being movably secured to the guide track, the guide track substantially limiting counterweight movement, relative to the motor, to one dimension, wherein the first cable system substantially reduces errors from the counterweight to the measuring member. - View Dependent Claims (15, 16)

17. A coordinate measuring machine comprising:
-
a motor; a measuring member; a counterweight; a pulley and cable system coupling the measuring member with the counterweight; and a guide track, the counterweight being movably secured to the guide track, the guide track substantially limiting counterweight movement, relative to the motor, to one dimension, wherein coupling between the measuring member and the counterweight results in the cable being non-vertical, and wherein the cable system substantially reduces errors from the counterweight to the measuring member. - View Dependent Claims (18, 19, 20)
