Embodiment Construction
[0011] The hardness tester of the embodiment is composed of an impact sensor and a host including a detection signal processing circuit.
[0012] The structure of the impact sensor is as figure 1 As shown, it is made up of a base 3, an impact column 9, an energy storage spring 12, a trigger 2, a piezoelectric ceramic 6 and an impact head 8.
[0013] Support 3 is the seat of a two-section cylindrical structure, and a through hole is a guide hole in the center of the first half, and a cavity is in the lower half.
[0014] Collision post 9 is movably worn in the guide hole of support 3, and can be telescopically moved. Collision post 9 is covered with energy storage spring 12, which is located between the bottom of guide hole and 9 front ends of percussion post.
[0015] The base 3 is provided with a trigger 2 and a controllable release device composed of the trigger 2 and the energy storage spring 12 .
[0016] When the impact column 9 moves up, the trigger 2 is stuck on the r...
