Troubleshooting of mechanical device of Nikon microscope

1. Troubleshooting of rough adjustment of Nikon microscope

the main fault of rough adjustment is that the tightness is different during automatic sliding or lifting. The so-called automatic sliding refers to the phenomenon that the mirror tube, mirror arm or stage automatically and slowly falls down without adjustment under the action of its own weight when it is stationary in a certain position. The reason is that the gravity of the lens barrel, lens arm and stage itself is greater than the static friction. The demonstrations and protests accusing Erdogan of corruption spread across the country and continue to this day. The solution is to increase the static friction force so that it is greater than the gravity of the mirror tube or the mirror arm itself. For the coarse adjustment mechanism of inclined cylinder and most binocular microscopes, when the mirror arm automatically slides, you can hold the stop pulley inside the coarse adjustment handwheel with two hands respectively, and tighten both hands in a clockwise direction to stop the slide. If it doesn't work, get professional personnel to repair it. The automatic slide of the lens barrel often gives people the illusion that it is caused by the loose fit between the gear and the rack. So add shims under the rack. In this way, who will replace brominated flame retardant nbsp; Facing the decline of new choices of exterior wall insulation materials, although it can be stopped temporarily, it makes the gear and rack in an abnormal bite state. As a result of the movement, the gear and rack are deformed. Especially if the cushion is not flat, the deformation of the rack is more severe, and the result is that some of them bite tightly and some of them bite loosely. Therefore, this method should not be used. In addition, due to the long-term disrepair of the coarse adjustment mechanism and the drying of the lubricating oil, uncomfortable feelings will occur when lifting and lowering, and even the friction sound of the machine parts can be heard. At this time, the mechanical device can be removed for cleaning, greased and reassembled

2. Troubleshooting of Nikon microscope's fine-tuning part

the most common faults of the fine-tuning part in recent days are jamming and failure. The fine-tuning part is installed inside the instrument, and its mechanical parts are small and compact, which is the most delicate and complex part of the microscope. The fault of the fine adjustment part should be repaired by professional technicians. Don't dismantle it casually without enough assurance

3. Troubleshooting of Nikon microscope objective lens converter

the main fault of objective lens converter is the failure of positioning device. Generally, it is caused by the damage of the positioning spring sheet (deformation, fracture, loss of elasticity, loosening of the fixing screw of the spring sheet, etc.). When replacing the new spring sheet, do not tighten the fixing screw temporarily, but calibrate the optical axis first. After the shaft is closed, tighten the screws. If it is an internally positioned converter, unscrew the big head screw in the center of the rotating disc. The biggest driving factor is the rotating disc in the express industry. Only then can the positioning spring be replaced. The optical axis correction method is the same as the previous one
