Description

Technical Field

[0001] The utility model relates to the field of load detection, and particularly relates to a mechanical load detection device. Background Technique

[0002] Load detection refers to the process of measuring and analyzing the load borne by an object or structure. The main purpose is to ensure that it can withstand the predetermined load during use and avoid failure or damage caused by overloading. Load detection is widely used in fields such as engineering structures, mechanical equipment, and transportation vehicles.

[0003] The detection methods usually include using sensors such as strain gauges, force sensors, etc. These sensors can monitor and record the force or pressure applied to the structure in real time. By analyzing this data, engineers can evaluate the safety, stability, and performance of the structure and make necessary design adjustments or maintenance. Load detection plays a crucial role in ensuring safety, improving reliability, and extending service life.

[0004] The method of load detection is to place the workpiece on the workbench, press it down through a hydraulic cylinder to apply pressure to the workpiece, and cooperate with the sensor to read the value to achieve detection. However, in order to ensure that the bottom of the workpiece is hollow, the traditional detection device directly places the workpiece on two long rods for pressure application, which will cause the displacement of the workpiece and result in incorrect data reading. Therefore, a mechanical load detection device is proposed to solve the above problems. Content of the Utility Model
