The invention discloses a measuring apparatus of displacements and pressures. The measuring apparatus of the displacements and the pressures comprises fixed blocks, a displacement sensor, a slider, a guiding-bar, a right fixed plate, a pressure sensor, a left fixed plate, and a fixed plate. The left fixed plate and the right plate are installed in a parallel mode at intervals. A screw bar is installed between the left fixed plate and the right fixed plate. The guiding-bar is installed between the left fixed plate and the right fixed plate, wherein the screw bar is parallel to the guiding-bar. A rolling wheel is installed on the end of the screw bar, wherein the end of the screw bar stretches out of the right fixed plate. The slider is installed on the screw bar and can move horizontally along the guiding-bar. The screw bar is provided with a spring, wherein the screw rod is installed between the left fixed plate and the slider. The screw bar is provided with the spring, wherein the screw bar is installed between the right fixed plate and the slider. One end of the displacement sensor is connected with the slider and the other end of the displacement sensor is fixed on the fixed blocks. One end of the pressure sensor is connected with the slider and the other end of the pressure sensor is fixed on the fixed plate. The measuring apparatus of the displacements and the pressures can achieve effects that the displacement parameter and the pressure parameter of a movement can be measured at the same time. Meanwhile, the measuring apparatus of the displacements and the pressures has the advantages of being simple in structure, clear in principles, and convenient to learn and grasp.

Technical field
The present invention relates to a kind of improvement of displacement and pressure measurement mechanism, particularly a kind of be applicable to impart knowledge to students be convenient to the displacement and pressure measurement mechanism observing and understand.
Background technology
In some occasion, we need to measure displacement and two parameters of pressure simultaneously, and for example the tire of Automobiles ' Safety Examination descends and dead weight capacity.In the existing measurement mechanism, measuring displacement and pressure great majority separately carries out, be special displacement or special measuring pressure, the device of measuring displacement and pressure one is also arranged, come from similar jack hydraulic cylinder and the source that produces displacement and pressure has, they have certain pollution to environment, and the measuring system rate of exchange are complicated, and cost is high.On the other hand, for teaching, the experimental box that the unit of many production instruments used for education provides mostly has too many closure, is not easy to observation of students and understanding.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of be applicable to impart knowledge to students be convenient to the displacement and pressure measurement mechanism observing and understand.
For achieving the above object, the technical solution used in the present invention is: a kind of displacement and pressure measurement mechanism comprises fixed block, displacement transducer, slide block, guide rod, right fixed head, pressure transducer, left fixed head, fixed head; Described left fixed head, right fixed head parallel interval arrange; Be provided with screw mandrel between described left fixed head, the right fixed head; The parallel screw mandrel of described guide rod is arranged between left fixed head, the right fixed head; The end that described screw mandrel stretches out right fixed head is provided with runner; Described slide block is arranged on the screw mandrel, and can be along the guide rod side-to-side movement; Be provided with spring on the screw mandrel between described left fixed head and the slide block; Be provided with spring on the screw mandrel between described right fixed head and the slide block; One end of described displacement transducer links to each other with slide block, and the other end is fixed on the fixed block; One end of described pressure transducer links to each other with slide block, and the other end is fixed on the fixed head.
Preferably, the parallel screw mandrel setting of described displacement transducer.
Preferably, described displacement transducer is connected on the slide block by the contiguous block that is arranged on the slide block.
Preferably, the parallel screw mandrel setting of described pressure transducer.
Preferably, the data that described displacement transducer, pressure transducer obtain after the A/D module converts, by data collecting module collected, then send controller to process respectively, and the result after the processing shows through display.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described displacement and pressure measurement mechanism of the present invention program can reach an action and make displacement and two simultaneously-measured effects of parameter of pressure; The present invention program is simple in structure, and principle is clear, is convenient to study and grasps, and has solved simultaneously the problem of experimental facilities closure, and this programme do not need hydraulic system, has avoided pollution on the environment.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of displacement and pressure measurement mechanism of the present invention;
Accompanying drawing 2 is the fundamental diagram of displacement and pressure measurement mechanism of the present invention;
Wherein: 1, fixed block; 2, displacement transducer; 3, contiguous block; 4, slide block; 5, guide rod; 6, right fixed head; 7, runner; 8, spring; 9, pressure transducer; 10, left fixed head; 12, fixed head.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1-2 is a kind of displacement and pressure measurement mechanism of the present invention, comprises fixed block 1, displacement transducer 2, slide block 4, guide rod 5, right fixed head 6, pressure transducer 9, left fixed head 10, fixed head 12; Described left fixed head 10, the 6 parallel interval settings of right fixed head; Be provided with screw mandrel (not marking) between described left fixed head 10, the right fixed head 6; Described guide rod 5 parallel screw mandrels are arranged between left fixed head 10, the right fixed head 6; The end that described screw mandrel stretches out right fixed head is provided with runner 7; Described slide block 4 is arranged on the screw mandrel, and can be along guide rod 5 side-to-side movements; Be provided with spring 8 on the screw mandrel between described left fixed head 10 and the slide block 4; Be provided with spring 8 on the screw mandrel between described right fixed head 6 and the slide block 4; One end of described displacement transducer 2 is connected on the slide block 4 by the contiguous block 3 that is arranged on the slide block 4, and the other end is fixed on the fixed block 1; One end of described pressure transducer 9 links to each other with slide block 4, and the other end is fixed on the fixed head 12; Described displacement transducer 2 parallel screw mandrel settings; Described pressure transducer 9 parallel screw mandrel settings; The data that described displacement transducer 2, pressure transducer 9 obtain after the A/D module converts, by data collecting module collected, then send controller to process respectively, and the result after the processing shows through display.
