Technical background
In the working angles of numerical control production and processing, be crucial to the information gathering of cutter.Traditional cutter pre-regulating system is to show with the enlarging projection of optical projection method by optical system, carrying out cutting tools measurement with the artificial vision aims at, this method by manual record tends to cause some artificial errors, too much dependence manually-operated not only influences the measurement operational quality in cutting tools measurement process in enormous quantities, and this measuring speed and efficient also are very low.Recent Development, also the method for useful line array CCD realizes cutter pre-regulating, but this method CCD when each test will once scan figure comprehensively, and this will take a long time.
Summary of the invention
Technology of the present invention is dealt with problems: overcome the deficiencies in the prior art, the cutter pre-regulating system with photoelectronic collimating location that a kind of time is short, efficient is high is provided.
Technical solution of the present invention: cutter pre-regulating system with photoelectronic collimating location, its characteristics are: it comprise X to Z to mobile system, illuminator, imaging system, video acquisition system and computer processing system and tested cutter, illuminator, imaging system and image capturing system place X to Z on mobile system, can be at X, motion in two free degree coordinate systems of Z, and its position can uniquely be determined, regulate X to the tested cutter of optical illumination that to mobile system illuminator is sent with Z, regulate the position of imaging system, the characteristic point zone that guarantees tested cutter is in the video acquisition scope, the tested cutter of the optical illumination that illuminator is sent, tested cutter carries out IMAQ by video acquisition system after the imaging system imaging, view data after the collection is sent into the boundary segmentation that computer processing system carries out image, edge to tested cutter carries out curve fitting, catch the boundary curve characteristic point, and finally calculate characteristic point and coordinate system deviation and, realize the preset of tested cutter.
Described illuminator is made up of the accurate value device of light emitting diode, light-conductive optic fibre and the optics of high brightness, and the light that light emitting diode sends is sent to the accurate value device of optics by light-conductive optic fibre.The light emitting diode that adopts high brightness is as light source, this light source is a cold light source, can avoid tested cutter to be heated and deformation takes place, the mode that adopts optical fiber to transmit, the tested cutter of optical illumination through the ejaculation of the accurate value of optics device, light source and tested cutter are isolated, and are that deformation takes place in order to prevent cutter to be heated, thus the measure error of avoiding.
Described imaging system is made up of image-forming objective lens, enocscope and amplification imaging object lens, and image-forming objective lens increases illuminance with the imaging that illuminator penetrates by enocscope, after amplifying by the amplification imaging object lens, carries out IMAQ by video acquisition system again.
Described video acquisition system is once gathered imaging by area array CCD.
The invention has the beneficial effects as follows, cutter pre-regulating system with photoelectronic collimating location, overcome the optical projection artificial vision and measured problems such as alignment error and line array CCD measurement aligning time length, improve accuracy, stability, the reliability of cutter pre-regulating greatly, thereby also improved accuracy of detection, machining accuracy greatly.Because area array CCD is Polaroid, therefore shortened the cutter pre-regulating time, improved production work efficient, have simple in structure, easy to operate, low cost and other advantages.
