Abstract
The utility model discloses a standard sensor of a roughness measuring gauge, which is composed of an inductance measuring head, wherein one end of the inductance measuring head (101) is connected with a measuring rod (102) and the inductance measuring head (101) is cylindrical. The standard sensor of the roughness measuring gauge has the advantages of being simple and reliable in structure, large in output power, strong in anti-jamming capability, not high in requirements for working environment, small and exquisite in appearance, convenient to carry and the like.
Description
Technical field
The utility model discloses the standard transducer of coarse measuring instrument, relate in particular to a kind of coarse measuring instrument that is used for measurement plane, periphery roughness and use standard transducer.Belong to and survey technical field of electronic equipment.
Background technology
In coarse measuring instrument prior art, sensor is all lumped together, and is regardless of kind, causes the measured value of some measured object to produce error, influences measuring accuracy; Perhaps sensor does not reach sensor at all, and sensor is not just worked and caused realizing measuring.In addition, the inductance probe and the sensor of traditional sensors weld, and do not adjust link, the difficult and difficult adjustment of assembling.
Summary of the invention
The purpose of the utility model is to overcome the weak point that exists in the above-mentioned prior art, thereby provides a kind of coarse measuring instrument that is used for measurement plane, periphery roughness to use standard transducer.
The utility model is to realize through following method:
A kind of standard transducer of coarse measuring instrument, its composition comprises inductance probe, an end of said inductance probe 101 is connected with measuring staff 102.
Said inductance probe 101 is cylindrical.
Said inductance probe 101 contacts with measured object 103 surfaces.
The sliding trajectory of said inductance probe 101 is perpendicular to the superficial makings of measured object 103.
Measured object 103 apertures that said inductance probe 101 is surveyed are greater than 5mm;
Measured object 103 degree of depth that said inductance probe 101 is surveyed are 0～22mm.
Said inductance probe 101 comprises contact pilotage and top guide.
One end of said measuring staff 102 can connect many identical measuring staffs 102.
Said measuring staff (102) is connected with screw with inductance probe (101).
The beneficial effect of the utility model: simple and reliable for structure, output power is big, antijamming capability is strong,, resolution higher, the error of indication be generally scale range 0.1%-0.2% less demanding to working environment, good stability, frequency response are high.

Embodiment
Further describe the utility model below in conjunction with accompanying drawing:
Embodiment 1:
A kind of standard transducer of coarse measuring instrument, its composition comprises inductance probe, an end of said inductance probe (101) is connected with measuring staff (102).
Further said inductance probe (101) is cylindrical.
Further said inductance probe (101) contacts with measured object (103) surface.
The sliding trajectory of further said inductance probe (101) is perpendicular to the superficial makings of measured object (103).
Measured object (103) aperture that further said inductance probe (101) is surveyed is greater than 5mm; The diameter of said inductance probe (101) is 5mm.
Measured object (103) degree of depth that further said inductance probe (101) is surveyed is 0～22mm; The effective length of said inductance probe (101) is 22mm.
Further said inductance probe (101) comprises contact pilotage and top guide.
One end of further said measuring staff (102) can connect many identical measuring staffs (102).When if measured surface or aperture are positioned at the depths, can insert the sensor of identical measuring staff (102) lengthening the utility model at the right-hand member of measuring staff (102), be convenient to stretch into measured object (103) in, obtain accurate measurement result.
Further said measuring staff (102) is connected with screw with inductance probe (101).
Embodiment 2:
End at standard transducer inductance probe (101) is equipped with measuring staff (102), during measurement inductance probe (101) is contacted with measured object (103) Surface Vertical, drags sensor with driving box with certain speed.Because measured object (103) surface profile peak valley rises and falls, inductance probe (101), when slide on the surface moves up and down generation at measured object (103).This motion synchronously moves up and down magnetic core through fulcrum, thereby the inductance value of two difference induction coils that are enclosed in the magnetic core outside is changed, and supplies subsequent treatment thereby convert displacement to electric signal.
