Embodiment
Below in conjunction with specific embodiment, the utility model is described further:
As shown in Figure 1, present embodiment comprises debugging pedestal 1, loads the Pressure Block 21 of counterweight 5, the transmission rod 22 of the contact pressure measurer 7 of the weight that connects Pressure Block 21 and transmit counterweight 5 to the tested anchor clamps 4, and described transmission rod and Pressure Block are one-body molded.Transmission rod 22 passes bar cover 11 and conflicts or separate with the contact pressure measurer on the tested anchor clamps 4.
The purpose of present embodiment is the contact pressure measurer that the weight that will be placed on all counterweights 5 on the Pressure Block 21 all conducts to tested anchor clamps 4, and the general assembly (TW)s such as the weight of the weight of measuring by contact pressure measurer and counterweight 5 and Pressure Block 21, transmission rod 22 contrast, according to this measurement precision of the pressure transducer of contact pressure measurer is judged, for the normal operation of contact pressure measurer provides the verification standard.Because contact pressure measurer is subject to the vertical normal force that socket spring applies in real work.Therefore, the transmission rod 22 of present embodiment vertically acts on the compressive region of contact pressure measurer, like this all is positioned over the weight vertical conduction of Pressure Block 21 top counterweights 5 to the compressive region of contact pressure measurer, improves the precision of measuring.Transmission rod 22 is that a diameter is the cylindric metallic object of 3～5mm with the compressive region contact position, acts on exactly in the very little pressurized zone guaranteeing.Bar overlaps 11 belows and also is provided with a bearing 3.Transmission rod 22 passes bar cover and bearing 3.The design of bearing 3 can guarantee that transmission rod 22 can move vertically, does not have in the horizontal direction the effect of component, guarantee that to greatest extent transmission rod 22 fully vertically acts on the compressive region of contact pressure measurer, and friction force is little, and is little to transmission rod 22 infringements.The quantity that is placed on the counterweight 5 of transmission rod 22 tops can be adjusted according to the range of contact pressure measurer size, and the weight summation of counterweight 5 and transmission rod 22 is with the formula of G=mg its actual newton's value that converts.Three support columns 12 of debugging pedestal 1 design, one of them is the fine setting support column, by the levelness that turn fine setting support column can be regulated debugging pedestal 1, guarantees to debug pedestal 1 horizontal positioned.Also design the tested anchor clamps 4 of the pressure transducer of a placement contact pressure test volume instrument on the debugging pedestal 1.These tested anchor clamps 4 can be changed according to the tested product of different demarcation, with the horizontal clamping of guaranteeing that tested product can be good.On the debugging pedestal 1 a release element 6 has been installed also.As shown in Figure 2, bar overlaps 11 outsides and is provided with screw thread, and release element 6 is threaded with bar cover 11, which is provided with one handle 61.By handle 61 rotation release elements 6, make release element 6 conflict with Pressure Block 2 or separate, and then the moving up and down of control transmission rod 22, can make pressure transducer unload the zero-pressure state that is depressed into from complete pressured state moment.
During the test contact pressure-measuring device, first put surveyor's staff at debugging pedestal 1, regulate the fine setting support column 12 of debugging pedestal 1, make debugging pedestal 1 state that is up to the standard.As shown in Figure 3, the pressure transducer 71 of contact pressure measurer 7 is placed horizontally on the debugging pedestal 1.Be rotated counterclockwise release element 6, make transmission rod 22 vertically be pressed on pressure transducer 71, and add the weight of the counterweight 5 that is equivalent to pressure transducer 71 doubling dose stroke pressures.By the release element 6 that turns clockwise, can mention transmission rod 22, pressure transducer 71 is in the zero-pressure state.Another mistake hour hands rotation release element 6 puts down transmission rod 22, and pressure transducer 71 is in the twice pressured state.Repeating said method makes pressure transducer 71 carry out fatigue impact.Pressure transducer 71 through fatigue impact has been removed internal stress, can carry out accurate adjustment work.At this moment, can put down transmission rod 22 fully, pressure transducer 71 is carried out the linearity debugging.Can on transmission rod 22, apply corresponding counterweight weight according to the different range of tested product with each spot pressure, pressure transducer 71 is carried out the linearity debugging and demarcates.
The above for explaining the preferred embodiment of the utility model, is not that the utility model is done any formal restriction only.All in lower any modification or change of making relevant the utility model of identical utility model spirit, all must be included in the category that the utility model is intended to protection.
