Abstract
Disclosed in the utility model is a portable pneumatic measuring instrument that belongs to a pneumatic measurement device. The utility model aims at providing a pneumatic measuring device with the advantages of compact structure and small size. The provided portable pneumatic measuring instrument comprises a measurement instrument body provided with a pressure sensor, a display electrically connected with the pressure sensor, and a measurement head communicated with a measurement channel of the measurement instrument body. The measurement instrument body includes a seat body (4) provided with an air chamber (7), an air inlet duct (15) and a measurement air channel (13) as well as a cover plate (5) for sealing the air chamber (7); the air inlet duct (15) communicated with the air chamber (7) is communicated with the measurement air channel (13) by a first limit hole (14); an air outlet duct (9) communicated with the air chamber (7) is communicated with the measurement air channel (13) by a second limit hole (10); the measurement head (6) and the display (1) are fixed at the seat body (4); and an overflow valve (11) is fixed at the outlet of the air outlet duct (9). The provided portable pneumatic measuring instrument can be directly installed at a machine tool for realizing on-line measurement.
Description
Technical field:
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of pneumatic measuring instrument for measurement mechanical part aperture size or circularity.
Background technology:
Pneumatic gauging is take pressurized air as medium, workpiece size to be carried out a kind of technology of non-cpntact measurement.Its principle is to change according to gauge head pressure in gas circuit when the surface of the work, utilizes pressure transducer that this pressure reduction is transformed into after electric signal by Computer Analysis, processes also display measurement result.At present, pneumatic measuring instrument usually by the measuring instrument body that is provided with pressure transducer, the display that is electrically connected to by chip and this pressure transducer, consist of with the gauge head that the measuring instrument body is communicated with by flexible pipe; Its shortcoming be loosely organized, volume is large, uses and carry inconvenience.
Summary of the invention:
In order to overcome the defective that exists in prior art, the utility model aims to provide a kind of compact conformation, portable pneumatic that volume is little is measured.
To achieve these goals, the utility model by the following technical solutions: it comprises the measuring instrument body that is provided with air chamber and measures air flue, be fixed on pressure transducer in described air chamber, the display with this pressure transducer electrical connection, the gauge head that is communicated with described measurement air flue; The measuring instrument body is provided with the pedestal of air chamber, air intake duct and measurement air flue by inside, air chamber sealing and the inner cover plate that is provided with exhaust duct are consisted of; Wherein, the air intake duct that is communicated with air chamber is communicated with the measurement air flue by the second metering hole by the exhaust duct that the first metering hole and measurement air flue are communicated with, are communicated with air chamber; Gauge head and display are fixed on pedestal, and the outlet of exhaust duct is fixed with surplus valve.
The exit of measuring air flue is provided with cushion chamber, and gauge head is fixed in this cushion chamber; Exit at surplus valve is fixed with filtrator; Be fixed with the inlet suction port that is communicated with air intake duct on pedestal.
Compared with the prior art, the utility model is owing to having adopted technique scheme, on the basis of traditional structure, display and gauge head are being fixed on the measuring instrument body, therefore simplify complete machine structure, dwindled machine volume, not only be easy to carry, and it can also be directly installed on and realize on-line measurement on lathe.
Description of drawings:

Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Fig. 1～2: the measuring instrument body by inside be provided with the pedestal 4 of air chamber 7, the cover plate 5 that is fixed on this pedestal air chamber 7 sealings consists of.Wherein, cover plate 5 inside are provided with the exhaust duct 9 that is communicated with air chamber 7, the measurement air flue 13 that pedestal 4 inside are provided with the air intake duct 15 that is communicated with air chamber 7 and are communicated with this air intake duct by the first metering hole 14, exhaust duct 9 is communicated with this measurement air flue by the second metering hole 10 that is located at pedestal 4 inside.Display 1 with power interface 2 is fixed on pedestal 4, and this display is electrically connected to pressure transducer 8 in being fixed on air chamber 7 by the chip (not shown); The gauge head 6 that is fixed on pedestal 4 is communicated with measurement air flue 13, and the outlet of exhaust duct 9 is fixed with for the surplus valve 11 of regulating the gas circuit pressure signal.
In order to eliminate the impact of airflow fluctuation, be provided with cushion chamber 12 in the exit of measuring air flue 13, gauge head 6 is fixed in this cushion chamber.For fear of air conducting and the gas circuit of contamination meter body interior is fixed with filtrator in the exit of surplus valve 11.For easy to use, be fixed with the inlet suction port 3 that is communicated with air intake duct 11 on pedestal 1.
