Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
Shown in Fig. 1～Fig. 3, the novel antioverloading testing apparatus for component dynamic impulsion of this practicality comprises topping base 1, force transducer 2, bottom base 3.
The test specimen 4 of test is fixedly connected on the upper surface of topping base 1; bottom base 3 is positioned at the lower section of topping base 1; therebetween between at a certain distance; force transducer 2 is fixedly connected on the lower surface of topping base 1; and be fixedly connected with bottom base 3 by unloading pin 5; for playing protection sensor 2, avoiding force transducer 2 to damage because of overload, the bearing capacity unloading pin 5 need to be less than the maximum range of force transducer 2.
Bottom base 3 is in opening up U shape structure, force transducer 2 is positioned at the cavity of this U shape structure on bottom base 3, the distance of the upper surface at the both ends of the lower surface distance U shape structure of topping base 1 need to be less than the distance of lower surface apart from the upper surface of the bottom of U shape structure of force transducer 2, the both sides of force transducer 2 are connected by unloading pin 5 respectively with the two ends of U shape structure, make unloading pin 5 after exceed the fracture of its supporting capacity by power, test specimen 4, topping base 1, when the entirety that force transducer 2 forms falls, topping base 1 first contacts with the both ends of U shape structure, the base contact of force transducer 2 with U shape structure can be avoided, thus avoid force transducer 2 because of rigid collision damage.
The upper surface at the both ends of U shape structure is provided with the first cushion plate 6, with the rigid shock reduced between topping base 1 and bottom base 3. The upper surface of the bottom of U shape structure is provided with the 2nd cushion plate 7, to reduce force transducer 2 because of rigid shock when Joint failure surprisingly falls and between bottom base 3.
Every side in the both sides of force transducer 2 need at least be provided with a unloading pin 5, and the unloading pin 5 of both sides is symmetrical arranged the best.In the present embodiment, every side of force transducer 2 unloads pin 5 by two respectively with the often end of U shape structure and is connected.
Unloading pin 5 can have various structures form and plurality of specifications size, to be adapted to the range ability of different force transducers 2. A kind of specific embodiment, as shown in Figure 4, unloading pin 5 is elongated, and its both ends are connected with force transducer 2 and bottom base 3 respectively, and middle part is provided with fluting 51 symmetrical up and down.
