The utility model is demarcated the axle pressure value that cylinder supply air pressure produces by pressure transducer, and determine compensation rate, to provide measurement data the most reliably, by displacement transducer, air bearing is carried out to the measurement of displacement in work and off working state, by adjusting the working pressure of air bearing and measuring at the displacement of corresponding pressure upper/lower positions sensor, detect and calculate the bearing capacity and stiffness value of this air bearing, there is good effect.
Other features and advantages of the utility model will be set forth in the following description, and, partly become apparent from instructions, or understand by implementing the utility model.The purpose of this utility model and other advantages realize by structure specifically noted in write instructions, claims and accompanying drawing and obtain.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail, to make above-mentioned advantage of the present utility model definitely.
Fig. 1 is the air bearing stiffness of the utility model three coordinate measuring machine and the structural representation of bearing capacity examination device.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail:
Specifically, as shown in Figure 1, the utility model technology, mainly through using cylinder as pressure elements, use precision pressure regulating element, the supply pressure of adjusting cylinders, the cylinder body be fixed on portal frame keeps relatively motionless, air pressure in cylinder can impel cylinder rod to move vertically, and corresponding pressure is applied to the air bearing of placing on the table, the bearing capacity and stiffness index of air bearing is measured by the levitation height of displacement sensor air bearing under operating air pressure state.
Specifically, a kind of air bearing stiffness of three coordinate measuring machine and bearing capacity examination device, comprise: left column 1 and right column 2, and connect the back timber 3 of left column and right column, left column and right column are parallel to each other, and arrange an air bearing 6 between the two, and the top of this air bearing is provided with a cylinder assembly, one end of described cylinder assembly contacts with described air bearing, and one end is fixed on described back timber.
Further, preferably, the cylinder rod 5 that described cylinder assembly comprises cylinder 4 and connects with cylinders, described cylinder rod contacts with described air bearing, and described in air cylinder driven, cylinder rod moves up and down.
Further, preferably, also displacement transducer is provided with, for measuring the levitation height of air bearing under operating air pressure state; Pressure transducer, demarcates for the axle pressure value produced cylinder supply air pressure.
Technical characterstic of the present utility model:
By pressure transducer, the axle pressure value that cylinder supply air pressure produces is demarcated, and determine compensation rate, to provide measurement data the most reliably.
Displacement transducer is used air bearing to be carried out to the measurement of displacement in work and off working state.
Simple and reliable for structure, cost is low, and efficiency is high, can demarcate, to meet the different needs to each air bearing.
The beneficial effects of the utility model are, can carry out accurately measuring rapidly and efficiently to air bearing, structure is simple, and accuracy of measurement is high, can provide reliable technical data to the Performance Detection of air bearing.
More particularly, described cylinder, it uses high pressure air to be cylinders providing power, by precision pressure regulating device adjustment air pressure size, the positive pressure value that corresponding pressure transducer calibration goes out, the output pressure of control cylinder, then uses displacement sensor air bearing position at this pressure, by adjusting the working pressure of air bearing and measuring at the displacement of corresponding pressure upper/lower positions sensor, detect and calculate the bearing capacity and stiffness value of this air bearing.
Such as, in one embodiment, what it used is the single-acting cylinder of square cylinder body, cylinder diameter 80mm, acting as of this cylinder, when high pressure air enters from the air inlet side of cylinder, cylinder can produce corresponding thrust, and according to F=PS, power output is the area that air inlet air pressure is multiplied by cylinder diameter, and the control of air inlet air pressure can use accurate voltage regulating valve regulation and adopt digital pressure gauge to detect, so just high resolving power and digitized quantization can be realized.
Wherein, displacement transducer, uses digital inductance amesdial, detect the Floating Height of air bearing under operating air pressure, by detecting the output pressure of different Floating Height lower cylinders, determine the bearing capacity situation of air bearing, and computable go out this air bearing etc. rigidity.
By test, the novel technical parameter that effectively can detect air bearing of this use, plays crucial effect to the quality controlling bearing.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
