Compared with the prior art, the high-precision pneumatic gauge for measuring bore diameter has the advantages of 1, simple and contact integral structure, easy manufacturing and low cost, 2, fast speed, convenience in operation, high measurement precision, adaptability to requirement of field batch inspection.

Description

Measure the pneumatic cubing of high precision in aperture
Technical field
The utility model relates to a kind of cubing, belongs to the checkout equipment technical field, refers in particular to a kind of pneumatic cubing of high precision of measuring the aperture.
Background technology
In aircraft industry and automobile industry, it all is very high that the manufacturing accuracy of key position part is required, though the aperture of some part reaches millimeters up to a hundred, tolerance but requires to be controlled in the 0.04mm, and this has brought great difficulty to detection.And the instrument general using slide calliper rule or the CMM in traditional measurement aperture, but all there are different shortcomings separately in this dual mode, though for example the slide calliper rule theoretical precision can reach 0.01mm, but be not easy to get that section line segment that just passes through the center of circle during owing to measurement, thereby the very difficult accurate pore size of measuring, though and the CMM measuring accuracy is high, can reach 0.0001mm, but it is very strict to the environmental requirement of using, requirement is measured under specific temperature, and instrumentation complexity, costliness need to train and could use through the special messenger, and are not suitable for carrying out at the scene large batch of full inspection production.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of pneumatic cubing of high precision of simple and reasonable, convenient to operation, the measurement aperture that is suitable for examining full production requirement is provided.
To achieve these goals, the utility model is realized by following technical scheme:
A kind of pneumatic cubing of high precision of measuring the aperture includes a pneumatic gauging assembly and a calibration block, and described pneumatic gauging assembly and calibration block connect by tracheae.
Further, also include a check and correction ring gauge, described check and correction ring gauge uses with pneumatic gauging assembly and calibration block and cooperates.
Further, described pneumatic gauging assembly includes handle and probe, and handle inside is provided with the plastics tracheae, and probe is arranged at handle one end and communicates with the plastics tracheae.
Further, described probe is circular ring structure, and its sidewall middle part is provided with a scrobicular ring, axially is provided with the straight hole that communicates with plastics tracheae and scrobicular ring respectively.
Further, the manufacturing tolerance of described probe is less than 0.005mm.
Further, described calibration block middle part is provided with the air flue that communicates with the plastics tracheae, is provided with buoy in the air flue, and the air flue arranged outside has scale, and scale interval is 0.002mm.
Further, the manufacturing tolerance of described check and correction ring gauge is less than 0.005mm.
The utility model compared with prior art, its beneficial effect is:
1, one-piece construction is simply compact, makes easily, and cost is low;
2, convenient to operation, the measuring accuracy height is suitable for on-the-spot large batch of full inspection production requirement.
In order to understand the utility model more clearly, set forth embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is the structural representation of the utility model pneumatic gauging assembly.
Fig. 2 is the structural representation of the utility model calibration block.
Embodiment
As shown in Figure 1, 2, the pneumatic cubing of high precision in measurement described in the utility model aperture, include a pneumatic gauging assembly 1, a calibration block 2 and a check and correction ring gauge (not drawing among the figure), described pneumatic gauging assembly 1 and calibration block 2 connect by tracheae, and described check and correction ring gauge uses with pneumatic gauging assembly 1 and calibration block 2 and cooperates.
Above-mentioned pneumatic gauging assembly 1 includes handle 11 and probe 12, and handle 11 inside are provided with the plastics tracheae, and probe 12 is arranged at handle 11 1 ends and communicates with the plastics tracheae.Further, described probe 12 is circular ring structure, and its sidewall middle part is provided with a scrobicular ring 121, axially is provided with the straight hole 122 that communicates with plastics tracheae and scrobicular ring 121 respectively.Preferably, the manufacturing tolerance of described probe 12 is less than 0.005mm.
Above-mentioned calibration block 2 middle parts are provided with the air flue 21 that communicates with the plastics tracheae, are provided with buoy 22 in the air flue 21, and air flue 21 arranged outside have scale, and scale interval is 0.002mm.
The manufacturing tolerance of above-mentioned check and correction ring gauge is less than 0.005mm.
Use principle of the present utility model is as described below: in the probe 12 of pneumatic gauging assembly 1 is put in the check and correction ring gauge, because the check and correction ring gauge is not overproof hole, aperture, when feeding gas, the slit is minimum between check and correction ring gauge and probe 12, only there is minimum portion gas from the slit, to reveal, most of gas can flow to calibration block 2 from the other end of pneumatic gauging assembly 1, thereby makes the buoy 22 rising certain altitudes in the calibration block 2, and this height gage is decided to be the zero graduation place; When being put into the probe 12 of pneumatic gauging assembly 1 in the measured hole again, because when manufacturing and designing, probe 12 is got the minimum value that design allows, when probe 12 can not be put tested aperture into, show that the aperture is too small, not in margin tolerance, and after probe 12 can be put into the aperture, feed gas this moment, buoy 22 on the calibration block 2 just rises to certain altitude, corresponding to a fixed numbers, the basic numerical value of check and correction ring gauge is added that the numerical value that shows on the calibration block 2 is exactly the measured value in aperture, thereby can measure the size in tested aperture fast and accurately.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model and modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
