19JPC all-purpose tool microscope (image-type)

Ⅰ Introduction 
   19LPC-V image-type all-purpose tool microscope is a new added image measuring system on the base of preserving all-purpose tool microscope performance. This system uses vidicon and special-purpose optical objective to substitute human''s eye to collimate and save video graph. Adopting election magnifying., its zoom multiple is greatly improved and it is convenient to observe small workpiece and precisely measure.
   Depending on high-precision track of all-purpose tool microscope, this system may realize high-precision image measuring in real meaning.
Ⅱ Use:
   19JPC-V image-type all-purpose tool microscope is a new generation of all-purpose tool microscope used in computer assistant measuring, which can solve each kind of complicated measuring problems. Traditional all-purpose tool microscope can not directly measure geometrical element in field of view, such as center of circle, midpoint, point of intersection, midline, and their distance, included angle and so on are hard to measure. But these are easy to do in 19JPC. This instrument adopts precise grating sensor, PC series and data interface gather to measure data, carry on data processing with 19JPC planar measuring program, display and print result. It is convenient to operate, only keying measuring command according to graphic menu displayed on screen. During the course of measuring, color display can timely display the coordination of collimated workpiece. Rectangular coordinate or polar coordinate may convert at any movement, which is especially convenient for measuring polar coordinate and cam. This instrument adopts metric system and British system. Calculating precision may reach 0.0001mm and 0.00001inch.It may self-correct assemble error of worktable track, further improving measuring precision.

Ⅲ Characters of instrument 
19JPC-V image-type all-purpose tool microscope adopts computer graph processing technology to carry on measured data processing on the base of 19JPC microcomputer-type all-purpose tool microscope. There is reticle collimation system in measuring software. When reticle meets tested objective, it will flicker and change color, therefore, it realizes precise collimation. This instrument is a kind of multi-use measuring instrument widely used in machinery, electron manufacturing, measuring and testing, also may be used to measure dimension, shape, angle and position of any part within measuring rang,

Typical measuring objects:
Measure the shape of each kind of molding part, example: templet, templet vehicle cutter, templet milling cutter, die and cam.
Measure mid-diameter, small-diameter, screw distance, tooth-like DBC case of male screw (Screw plug guage, silk perch, worm, etc)
Measure leading distance, tooth-like and tooth-like DBC of gear hob.
Measure circuit board, drilling mold, or hole position of hole board, symmetry of key sit and other shape and position errors.
Main microscope is equipped with multi eyepieces and objectives, great field of view and clean imaging.
Adopt photoelectricity digital-display technology; take precise grating ruler as measuring component; adopting advanced computer technology, input timing length signal gathered by grating digital-display system into computer; special-purpose planar measuring soft carries on data processing, prints result or graph, correctly and effectively.
Main microscope may swing to left and right, used to measure screw part.
Take non-contact measuring as basic method, transmission and reflection illuminating, and examine part with complicated geometrical shape.
Complete accessories, broad use range.

2. Image measuring software
It is a computer planar graph processing system specially developed for all-purpose tool microscope and measuring microscope. This system uses computer image processing technology to tie in computer and optical instrument, which is a intelligent effective measuring tool to make measuring course more convenient and direct.
There is reticle collimation system in software. When reticle meets testes object, it will flicker and change color; therefore, it realizes precise collimation.
The software adopts WINDOWS interface; reticle paints points though image forming in wrokpiece software.; and may measure point, line, circle, arc, angle, beeline, roundness, screw, etc. After measuring, figure graph of workpiece is displayed on computer screen; each kind of calculating is finished by mouse.. All measured data may be output by system printer; graphic file can also be converted to file format that CAD can open to edit.
