Abstract
A single-axial precision measuring apparatus includes a base, a flatbed at the base, a flattening mechanism and a monitor above the flatbed, and a distance measuring mechanism below the flatbed. The characteristics of the invention are that, the flatbed is a transparent plate having a plurality of ventilation openings that are connected with a suction tube of a vacuum suction device; the flattening mechanism is capable of up-and-down displacements, and has multi-sectional halt heights through program controls; and the distance measuring mechanism disposed below the flatbed is capable of transverse movements, and at least has an optical ruler, a laser positioning element and CCD cameras. Wherein, the CCD cameras focus at the measuring points, and transmit images captured to the monitor.
Claims5
A single-axial precision measuring apparatus comprising a base, a flatbed at the base, a monitor above the flatbed, and a distance measuring mechanism below the flatbed;
- and the characteristics being that:
- the distance measuring mechanism below the flatbed captures images in an upward direction, and calculates relative center positions of two to-be-measured images captured by charge coupled devices (CCD) using measurements read by an optical ruler disposed in parallel with a single-axial sliding track, thereby obtaining a length between two measuring points;
- the flatbed is a transparent plate having a plurality of ventilation openings that are connected with a suction tube of a vacuum suction device;
- and
- the distance measuring mechanism disposed below the flatbed is capable of transverse movements, and at least has an optical ruler, a laser positioning element and CCD cameras;
- wherein the CCD cameras focus at the measuring points, and transmit the images to the monitor.
