How to repair and maintain the image measuring instrument?

How to repair and maintain the image measuring instrument? The image measuring instrument is a high-resolution instrument, consisting of a high-resolution CCD color lens, a continuous zoom objective lens, a color display, a video cross-line display, a precision grating ruler, a multi-function data processor, data measurement software and a high-precision workbench Structure and composition. The common failures of common common image measuring instruments are divided into lift drive failure, workbench failure, projection screen failure, projection imaging failure, image imaging failure, electrical failure, electronic failure and accuracy failure.

1. The lift drive is faulty. It is common that abnormal sounds occur during the lifting process, unable to rise, fall, fall, fall, and bounce, there is a large space-time gap during the transmission process, fine-tuning is performed without transmission, and the projection screen frame is loose. 2. The workbench is faulty. Under normal circumstances, the polishing rod is easy to spin, the transmission of the polishing rod bounces, the friction transmission is uneven, the movement of the workbench will produce screams, and the movement of the workbench will stop. When solving the problem, find out the cause of the problem, and then prescribe the correct medicine. The spring can be adjusted by tightening the screws, replacing the bearing, changing the oil, adding lubricating oil, replacing the polished rod and adjusting or replacing the polished rod bracket. 3. The projection screen is faulty. When rotating, it makes a sound, which can remove impurities such as rust on the end surface, and can replace a new positioning bearing. The friction is high when rotating, you can loosen the lock 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 grinder, weld the signal line, and then connect the plug. 4. Projection imaging fails. Image blur, dark areas on the image, dark spots on the image, contrast light in the dark areas on the image, etc. You can clean the objective lens, projection screen, workbench glass, condenser, reflector, etc., 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 a black screen is displayed, you can check whether the power cord is properly connected, power supply voltage, etc., and plug in the signal line of the monitor. If the parts are damaged, the display or front sight generator needs to be replaced. When the objective lens is zooming, if the deviation between the crosshair and the aiming point is large, please readjust the screw that locks the lens barrel or replace the lens barrel. When there is a shadow on one side of the workpiece to be tested, the screws on the four corners of the camera or glass can be adjusted to straighten the workpiece. 6. Electrical failure. Common faults are that the bulb does not turn on, the axial fan does not rotate, the bulb is easy to burn, the fuse is easy to burn, and the transformer is overheated and damaged. 7. Electronic failure. If the electric box key fails, you can clear the system and replace it with a new mask; if the axis is not counting, you can replace the slider or OP board or the entire scale, reconnect the signal cable, and replace the main board. If the digital tube has no stroke, it needs to be replaced or repaired. 8. Accuracy failure. Including axis error, poor measurement accuracy of the two coordinates, large angle indication error, large measurement error on different planes, etc., in order to deal with such failures, please pay attention to correction and adjustment. If you want to reduce the trouble of the image measuring instrument, 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 mildew on the surface of the optical parts, rust on the metal parts, dust, debris, etc., keep the surface of the parts clean, do not touch the image measuring instrument, and clean them frequently.
