Metallographic specimen automatic milling electro-optical device
Technical field
The present invention relates to a kind of mechanical polishing device preparing metallographic specimen, in metal material tissue performance study and failure analysis work.
Background technology
Metallographic examination is for analytical approach means the most conventional a kind of in metal material tissue performance study and failure analysis, be widely used in metallurgy, machinery, casting, petrochemical industry, the industries such as electric power, and quality prepared by metallographic specimen is the key factor of guaranty money's facies analysis structure observation and assay correctness, the wherein sampling of analytical sample, polish, polishing is the necessary process of metallographic specimen preparation, metallographic specimen grinding and polishing equipment is that metallography preparation raises the efficiency the important means with quality, formers existing a large amount of is at present available, but all there is various deficiency, sample needs manually to change varigrained sand paper in polishing multiple working procedure process from coarse to fine, on artificial hand-held sample polished machine, grinding not only expends time in length, labour intensity is large, inefficiency, there is potential safety hazard and dust pollution especially in the course of the work to the impact of human body.
Summary of the invention
The invention provides a kind of metallographic specimen automatic milling electro-optical device, solve existing apparatus and there is labour intensity greatly, ineffective problem.
The present invention is overcome the above problems by following scheme:
A kind of metallographic specimen automatic milling electro-optical device, comprise cabinet, the case face of cabinet is fixedly installed armstand, armstand is provided with horizontal outrigger, be provided with liftable in the end of horizontal outrigger and regulate platform, regulate on platform at liftable and be provided with steer motor, the output shaft stretched out downwards of steer motor is connected with platter, platter is provided with ventricumbent specimen holder, sample is provided with in specimen holder, the case face of cabinet is provided with sand paper clamp box, the sand paper wheel of consulting and sand paper pallet is provided with in the side of sand paper clamp box, rectangle sandpaper disk is provided with in sand paper clamp box, rectangle sandpaper disk is provided with chute, bearing pin is movably set with in chute, bearing pin is fixedly installed on gear wheel, gear wheel is connected with the output shaft of drive motor by pinion wheel, drive motor is arranged in cabinet, the base plate of sand paper clamp box is provided with electromagnet, spring is provided with between the base plate and rectangle sandpaper disk of sand paper clamp box, steer motor, drive motor and electromagnet are all electrically connected with the single-chip microcomputer be arranged in cabinet.
Be provided with hair-dryer in the chassis, the purge nozzle of hair-dryer is arranged on the case face of cabinet, and the side of cabinet is provided with control panel.
The feature that the present invention has automated cleaning, certainly moves sand paper, automatically changes polishing direction, continuous batch can be facilitated to prepare metallographic specimen, and work efficiency and processing safety are all high.

Fig. 1 is the structural representation of main apparent direction of the present invention;
Fig. 2 is the structural representation in side-looking direction of the present invention;
Fig. 3 is the structural representation of rectangle sandpaper disk 10 of the present invention.
a kind of metallographic specimen automatic milling electro-optical device, comprise cabinet 1, the case face of cabinet 1 is fixedly installed armstand 16, armstand 16 is provided with horizontal outrigger, be provided with liftable in the end of horizontal outrigger and regulate platform 5, regulate on platform 5 at liftable and be provided with steer motor 4, the output shaft stretched out downwards of steer motor 4 is connected with platter 14, platter 14 is provided with ventricumbent specimen holder 15, sample is provided with in specimen holder 15, the case face of cabinet 1 is provided with sand paper clamp box 11, be provided with sand paper to consult wheel 6 and sand paper pallet 7 in the side of sand paper clamp box 11, rectangle sandpaper disk 10 is provided with in sand paper clamp box 11, rectangle sandpaper disk 10 is provided with chute 21, bearing pin 9 is movably set with in chute 21, bearing pin 9 is fixedly installed on gear wheel 3, gear wheel 3 is connected with the output shaft of drive motor 8 by pinion wheel 2, drive motor 8 is arranged in cabinet 1, the base plate of sand paper clamp box 11 is provided with electromagnet 13, spring 12 is provided with between the base plate and rectangle sandpaper disk 10 of sand paper clamp box 11, steer motor 4, drive motor 8 and electromagnet 13 are all electrically connected with the single-chip microcomputer 19 be arranged in cabinet 1.Drive motor 8 drives gear wheel 3 to rotate by pinion wheel 2, and gear wheel 3 realizes the left and right reciprocally swinging of rectangle sandpaper disk 10 by the slip of bearing pin 9 in chute 21 on it, thus polishes the sample arranged in specimen holder 15.
in cabinet 1, be provided with hair-dryer 18, the purge nozzle 17 of hair-dryer 18 is arranged on the case face of cabinet 1, and the side of cabinet 1 is provided with control panel 20.
in the process of grinding, purging wind is sent from purge nozzle 17 by hair-dryer 18 timing, cleans sand paper clamp box 11.
after one grinding process completes, sand paper clamp box 11 reduces, clamping sand paper is unclamped, sand paper rub wheel 6 is rotated and is brought sand paper thinner for next granularity into sand paper clamp box 11, and the used sand paper of front one grinding process is ejected, under spring 12 acts on, make rectangle sandpaper disk 10 rising coordinate with sand paper clamp box 11 after electromagnet 13 power-off sand paper is clamped.Steer motor 4 drives platter 14 to rotate 90 °, mutually vertical to ensure next process and the metallographic specimen of upper procedure direction of polishing, and the cut grinding that a upper procedure polishing produces can be removed by next process.
The work such as in whole polishing operation, polishing time in each stage and polishing speed arrange and inputted by front-end control panel 20, and the sand paper controlling each stage by built-in single-chip microcomputer 19 is changed, clamping, the change in polishing direction, sample polishing, blowing are clean.
