Description

Technical Field

[0001] The utility model relates to the technical field of mechanical measurement, in particular to a load loading device for mechanical measurement. Background Art

[0002] Common mechanical metrology verification methods at work include weighing, capacity, measurement and hardness measurement. Weighing is a measuring instrument that uses various weighing principles such as gravity acting on an object to determine mass or other values, values, parameters or characteristics as a function of mass. When measuring the load of an object, the external force is continuously applied to the surface of the object to be tested, and the deformation of the object is observed under the action of gravity until the object breaks to determine the object's ultimate load-bearing capacity. During the load measurement process, the force is vertically downward and can only act on the same position of the object, which is not convenient for testing the load-bearing capacity of different positions of the object to be tested. For this reason, we propose a load loading device for mechanical metrology. Utility Model Content

The pressure rod is driven to move by moving the slide in the load-bearing bracket, and then the pressure rod can load and press down different positions of the object to be detected.

The bearing plates can be used in groups to support the objects to be inspected.
