Adjustment of Microscope Elevating Structure
1. The lifting mechanism of the straight Olympus microscope condenser includes: 1. Celluloid washer 2. Thumb screw 3. Eccentric gear rod sleeve 4. Gear rod 6. Lifting handwheel 7. When adjusting the binocular nut, one Insert the binocular nut wrench with one hand into the binocular nut on the end face of the handwheel, and use the other hand to insert a screwdriver into the notch of the thumb screw at the other end, and tighten it firmly to stop the slide.
2. Inclined cylinder Olympus microscope Condenser lifting mechanism:
When adjusting, first use a screwdriver to withdraw the resident screw in the middle of the binocular nut for 1 to 2 turns. The bearing washer is tightly fitted with the resident screw, so it will also withdraw along with it and break away from the end face of the gear rod. Then, use the double-eye nut wrench to screw the double-eye nut into the adjustment seat. At the same time, use the other hand to turn the handwheel and carry out the test until the lifting mechanism is properly tightened and can stay at any position before stopping the screwing of the binocular nut. Finally, put the stop screw in again so that the bearing washer touches the gear rod. The reason why such an adjustment can eliminate faults is because the inner hole of the adjustment seat is tapered. The tapered bushing has notches in the axial direction. When the double-eye nut 1 is screwed inward, the tapered sleeve is pushed inward, so that when the tapered sleeve advances, the notch becomes smaller, the inner hole shrinks, the gear rod is clamped tighter, and the friction of the gear rotation is increased. resistance, thereby stopping the automatic drop
Definition of Inverted Metallographic Microscope
Inverted metallographic microscope is an important instrument for metallographic research, mainly used to identify and analyze the internal structure of metals. Inverted metallographic microscopes can be used for quality research of casting, smelting, heat treatment, inspection of raw materials or analysis of materials after processing.
The inverted metallographic microscope system is an organic combination of a traditional optical microscope and a computer (digital camera) through photoelectric conversion. It can not only perform microscopic observation on the eyepiece, but also observe real-time dynamics on the computer (digital camera) display screen. images, and can edit, save and print the required pictures.
Inverted Metallographic Microscope When operating, the observation surface of the sample is downward and coincides with the working surface, and there is no requirement for the height and parallelism of the sample, which is suitable for irregular or large samples. Inverted metallographic microscopes are widely used in factories, laboratories, teaching and scientific research and other fields.
