Three-dimensional coordinate measurement apparatus
First Claim
1. A three-dimensional coordinate measurement apparatus comprising:
- a surface plate configured to place a measuring object; and
a Y carriage configured to support a measuring probe, the Y carriage supported by two strut members which are across the surface plate and movable in a Y-axis direction of the surface plate,wherein the two strut members include a first strut member provided with a driving mechanism configured to drive the Y carriage in the Y-axis direction, and a second strut member configured to move following the first strut member,a guide portion parallel to the Y-axis direction is formed in the surface plate on a first strut member side,side surface support members which support the first strut member on the surface plate by holding both opposed side surfaces of the guide portion, are provided, andthe side surface support members are arranged separately from each other along the Y axis direction with the driving mechanism interposed between the side surface support members.

Abstract
There is provided a three-dimensional coordinate measurement apparatus capable of reducing shaking of a Y carriage and improving measurement accuracy. A groove is formed along a Y-axis direction in a right side part of a surface plate made of stone, and a Y guide is formed between the groove and a right side surface of the surface plate to support a Y carriage in a portal shape in a movable manner in the Y-axis direction. A support section is provided at a lower end of a right Y carriage on the right side of the Y carriage, and the support section is supported by the surface plate through air pads which are disposed by two air pads back and forth on the corresponding one of a top surface, a right side surface, and a bottom surface, of the surface plate, and a right side surface of the groove.
