What are the common faults of Hefei image measuring instrument


Common faults of the image measuring instrument are divided into lifting drive failure, table failure, projection screen failure, projection imaging failure, image imaging failure, electrical failure, electronic failure, and accuracy failure.
1. Lifting drive failure. Common are abnormal noises during lifting, unable to rise, falling, falling, falling, bouncing, large space-time gap during transmission, fine adjustment without transmission, and loose projection screen frame.
2. The workbench is faulty. Generally, it is prone to idling of the polished rod, bouncing of the polished rod transmission, irregularity in friction transmission, squeaking of the table movement, and stagnation of the table movement. When solving the problem, find out the cause of the problem, and then prescribe the right medicine. The spring can be adjusted by tightening the screws, replacing the bearings, re-greasing, lubricating, replacing the polished rod, adjusting or replacing the polished rod bracket, and so on.
3. The projection screen is faulty. When there is sound during rotation, the impurities (such as rust stains) on the end face can be cleaned, and the new positioning bearing can be replaced. The friction force is strong when rotating, you can loosen the locking screw or change the friction rotation. When the rotation is uneven, you can replace the dial seat, friction wheel, friction wheel shaft, etc. When the projection screen rotates and does not count, you can tighten the angle friction machine, weld the signal cable, and connect the plug.
4, projection imaging failure. The imaging is blurred, the imaging has dark areas, the image has dark spots, and the imaging contrast is dark. The objective lens, projection screen, table glass, condenser, reflector, etc. can be cleaned. Adjust or replace the filament. If the power supply voltage of the bulb is too low, install a total power regulator.
5. Imaging failure. When the black screen is displayed, you can check whether the power cord is properly connected, the power supply voltage, etc., and plug in the signal cable of the monitor. If the parts are damaged, you need to replace the monitor or the crosshair generator. When the crosshair deviates from the exact point when the objective lens is zoomed, readjust the screw that locks the lens barrel, or change the lens barrel. When there is a shadow on one side of the work under test, adjust the screws on the four corners of the camera or glass to straighten the workpiece.
6. Electrical failure. Common faults are that the light bulb does not light, the axial fan does not turn, easy to burn bulbs, easy to burn fuses, transformers are overheated, and damaged.
7. Electronic failure. If the electrical box keys fail, the system can be cleared and replaced with a new mask; if the shaft is not counting, the slider or the OP board or the entire ruler can be replaced, the signal cable can be reconnected, and the motherboard can be replaced. If the digital tube lacks strokes, it needs to be replaced or repaired.
8. Accuracy failure. Including the inaccuracy of the axi axis, the poor accuracy of the two coordinate measurement, the large error of the angle indication, and the large measurement error of different planes. To deal with this kind of failure, pay attention to correction and adjustment.
If you want to make the image measuring instrument less trouble, you must pay attention to the maintenance of the instrument. The storage environment of the instrument is very important. It should be placed in a clean and dry room to avoid mold on the surface of optical parts, rust of metal parts, and peeling of dust and debris. Keep the surface of the parts clean, do not touch them, and clean them frequently.
