The gantry type image measuring instrument is mainly used for non-contact detection of geometric dimensions, shapes, and positional tolerances of workpieces. It is a precision length measuring instrument that integrates optics, precision machinery, and electronic measurement.
The tested workpiece is placed on the workbench and illuminated by LED surface light or contour light. The image of the tested part is captured by a zoom objective lens and a color CCD camera, and then transmitted to the computer and display through the S terminal. The software uses the video crosshairs generated on the monitor as a reference for aiming measurement. It drives the optical ruler to move in the X and Y directions through the workbench to obtain the coordinate values of various points in space. These values are then transmitted to the computer through an adapter card and programmed for automatic geometric calculations, completing the automatic measurement and collection of data.
Instrument Features
High resolution and magnification: Equipped with a high-resolution CCD camera and a good optical lens, it can clearly capture the details of the workpiece and achieve high-precision measurement.
Multiple measurement functions: It can measure basic geometric elements such as points, lines, circles, and arcs, as well as perform combined element measurements such as calculating center to center distance and tangent lines. It can also measure form and position errors such as concentricity and true roundness, and has multiple functions such as coordinate system setting, comparison, and dimension annotation.
Automated measurement: Driven by servo motors and combined with computer software, it can achieve automated measurement functions such as edge finding measurement and frame selection measurement. It can also perform automatic programming and batch testing to improve measurement efficiency and accuracy.
Light source system: equipped with programmable LED cold light source, including bottom light and top light. The bottom light can illuminate the image window with uniform light, and the top light is a two ring four item light with a certain angle, which has good measurement effect. The light source intensity and angle can be adjusted according to different measurement needs to improve measurement accuracy.
Daily cleaning and dust prevention: Use a dust-free cloth to wipe the workbench glass, guide rails, and lenses daily to avoid dust and oil accumulation that may affect accuracy.
Environmental control: The equipment should be placed in a dry and dust-free environment (temperature 20 ℃± 5 ℃, humidity<60%), avoiding direct sunlight and vibration.
System updates: Regularly upgrade software to fix vulnerabilities and backup measurement data.
