Embodiment
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
The utility model provides a kind of multi-functional Charpy impact machine tester; It is through being provided with a plurality of positioning screw holes on base plate; Different sample bearings realize to be installed, and fix on the different sample bearings treat that the impact material sample is also corresponding different, the brake hard when the utility model also utilizes slip clutch to be implemented in the pendulum whereabouts simultaneously; Friction catch through slip clutch can make whole pendulum realize braking, can effectively improve the security of pendulum work.
See also Fig. 1, Fig. 2, shown in Figure 3, Fig. 1 is the front view of the utility model; Fig. 2 is the left view of the utility model; Fig. 3 hangs the structural representation of putting pendulum device for the utility model.The described multi-functional Charpy impact machine tester of the utility model; Comprise base plate 1, be fixedly mounted on sample bearing 9 and column 2 on the base plate 1; Said sample bearing 9 is fixed through being arranged on the base plate 1 a plurality of positioning screw holes; Therefore whole sample bearing 9 can be changed, and according to different impulse test requirements, replaceable different bearing.
Be installed with a display device 4 in balance staff seat side, raise the pivot angle degree through what this display device 4 can corresponding show pendulum.
As shown in Figure 4, Fig. 4 is the semi-girder test seat structure synoptic diagram of the utility model sample bearing preferred embodiment one.Hard-wired on the base plate 1 among this embodiment is pedestal 17; Be provided with groove in the said pedestal 17; Sample 19 is fixed in the groove, and a side is fixing through level pressure piece 18, and opposite side is fixing through dynamic pressure piece 20; Be provided with screw 21 and nut 22 in the bottom of dynamic pressure piece 20, the constant depth of sample 19 adjusted with realization; And it is fixing in dynamic pressure piece 20 1 sides through clamping screw 23.
As shown in Figure 5, Fig. 5 is the brugger test seat structure synoptic diagram of the utility model sample bearing preferred embodiment two.Hard-wired on the base plate 1 among this embodiment is pedestal 24; Said pedestal 24 is provided with a fixed orifice, and this fixed orifice is communicated with outside screw 27, and gland 25 is placed this fixed orifice; Sample 26 is placed gland 25; Fixing through screw 27, gland 25 is clamped sample 26, be convenient to the impulse test of pendulum.
As shown in Figure 6, Fig. 6 is the wedge test seat structure synoptic diagram of the utility model sample bearing preferred embodiment three.Hard-wired on the base plate 1 among this embodiment is pedestal 28, and said pedestal 28 is provided with and impacts pull head 29, impacts on the pull head 29 being fixed with sample 30, and a side of sample 30 is provided with sensor 31, can measure the dynamics that pendulum 7 impacts through sensor 31.
