Abstract
A coordinate-measuring machine has a vertical column which is linearly guided in one horizontal direction (x) and on which a measurement arm is guided for vertical displaceability. The linear movement (x) is produced by a carriage in which the column is mounted for rotational displacement about a vertical axis. A workpiece to be measured is mounted to a turntable. The construction provides a coordinate measuring machine having four axes, two linear and two rotational, and the machine is structurally compact in terms of the measurement volume which is achievable.
Claims11
A coordinate-measuring machine, comprising:
- a stationary machine part;
- a carriage supported by and guided for a single direction of horizontal displaceability on said stationary part;
- a column extending vertically from said carriage, and rotary-bearing means on said carriage establishing a vertical axis of rotary displaceability of said column;
- a measuring arm supported and guided for vertical displaceability along said column;
- first drive means for displacing said carriage in its horizontally guided direction;
- second drive means for rotary displacement of said column about said axis;
- and
- measurement systems on said carriage for measuring carriage-misalignment displacement in the direction perpendicular to said single direction of carriage displaceability and/or incremental carriage rotation about the vertical.
A coordinate-measuring machine, comprising:
- a stationary machine part;
- a carriage supported by and guided from a single direction of horizontal displaceability on said stationary part, said single direction extending from one to the opposite longitudinal end of said machine, with carriage guidance terminating short of said opposite end;
- a column extending vertically from said carriage, and rotary-bearing means on said carriage establishing a vertical axis of rotary displaceability of said column;
- a measuring arm supported and guided for vertical displaceability along said column;
- first drive means for displacing said carriage in its horizontally guided direction;
- second drive means for rotary displacement of said column about said axis;
- a workpiece-support turntable mounted to said stationary part for rotation about a vertical axis near said opposite end;
- and
- a vertically oriented probe magazine arranged at said one longitudinal end, said magazine having provision for storage of plural probes in vertically aligned array, whereby for all guided positions of said carriage, the vertical axis of column rotation is longitudinally between the magazine and the turntable.
A coordinate-measuring machine, comprising:
- a stationary machine part;
- a carriage supported by and guided for a single direction of horizontal displaceability on said stationary part;
- a column extending vertically from said carriage, and rotary-bearing means on said carriage establishing a vertical axis of rotary displaceability of said column;
- a measuring arm supported and guided for vertical displaceability along said column;
- first drive means for displacing said carriage in its horizontally guided direction;
- second drive means for rotary displacement of said column about said axis;
- a turntable mounted to said stationary part, and third drive means for rotary displacement of said turntable;
- and
- control means connected for coordinated control of said first, second and third drive means.
