This utility model discloses a real-time accurate preload testing device for high-strength bolts, relating to the field of engineering testing technology. The utility model includes a base plate with four sliding shafts fixedly connected to its top. Testing mechanisms are mounted on the four sliding shafts, and an error reduction mechanism is provided on the top of the base plate. By manually pulling and releasing the limiting plate, the device automatically engages with the second fixed shaft using the reaction force of a second spring, quickly locking the height of the first fixed plate. Finally, by pressing down on the housing, the device moves downwards along the positioning shaft. During this process, the built-in first spring continuously applies pressure to the first telescopic shaft and the ultrasonic probe, ensuring acoustic coupling between the probe and the lower surface of the first fixed plate. Then, rotating the lead screw drives the limiting shaft to clamp the housing, ultimately achieving rigid fixation of the entire measuring device. This ensures the stability of the ultrasonic probe during measurement and improves the accuracy of the preload test data.
