Abstract
A strain measurement device of multi-path and quick type is prepared as connecting component to stain transducer being connected with transducer connection line, setting multi-path quick-plug connector on said strain measurement device, connecting transducer connection line to multi-path quick-plug connector and connecting multi-path quick-plug connector to strain measurer.
Description
(1) technical field
The invention belongs to the material stretch test machine field, relate in particular to a kind of strain gauge means.
(2) background technology
The folder formula strain of prior art is extended and is counted folder formula structure, can only be used on the material stretch test machine.Its principle of work such as Fig. 1～shown in Figure 3: when being used for cupping machine, by clamping components 4 and ox-hide muscle (or spring) 2 strain transducer 1 is fixed on the tested tensile test specimen 3, sensor connecting line 5 is received on the controller of testing machine, just can measure, show and control the tension test process; To large-scale component can only be on its surface direct adhering resistance strain sheets,, again the other end of lead is connected on the strainmeter foil gauge lead-in wire and wire bonds with the weldering ferrochrome together, realize the measurement of strain.
The shortcoming that existing strain gauge means exists is: 1, the strain transducer of prior art can only singly only be used on the material stretch test machine; The multi-point sampler that 2, can not be used for engineering component, the large tracts of land that has influenced this class sensor is promoted the use of; 3, strain transducer is installed inconvenience, and use bothers, connection reliability is relatively poor.
(3) summary of the invention
In order to overcome the deficiency that can only singly only use, can not be used for multi-point sampler of existing strain gauge means, the invention provides a kind of can singly only the use, also can multichannel use simultaneously, can realize the fast multi-path strain measuring device of multimetering.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of fast multi-path strain measuring device, comprise the strain transducer, sensor connecting line, the strain gauge that are connected with tested member, described strain transducer is connected with the sensor connecting line, described strain gauge means also comprises the push-in connector of multichannel, described sensor connecting line is connected with the push-in connector of described multichannel, and the push-in connector of described multichannel is connected with strain gauge.
As preferred a kind of scheme: described strain transducer is installed on the magnetic suction base, and described magnetic suction base is provided with the surface of contact with the profile coupling of tested steel member.
As preferred another kind of scheme: described magnetic suction base is provided with the circular arc surface of contact that cooperates with the profile of cylindrical steel member.Certain, the surface of contact of magnetic suction base also can be other shapes such as arch, mates as long as satisfy with the profile of tested steel member.
Technical conceive of the present invention by: formed by magnetic suction base strain transducer, the push-in connector of multichannel and strain gauge.During use, magnetic suction base strain transducer is installed in tested component surface, be connected with strain gauge by the push-in web member of multichannel, can sample simultaneously, store and show the strain value of each channel sensor by the road with the adaptor that is complementary with web member.Magnetic suction base strain transducer can be used in material stretch test machine separately, substitutes folder formula strain extensometer commonly used now; Also can with the supporting use of strain gauge means.
Adopt magnetic suction base formula strain transducer, as long as satisfy and the profile of tested steel member and the surface of contact coupling of magnetic suction base, during use,, the push-in connector of connecting line and multichannel is connected gets final product as long as the surface of contact of magnetic suction base is placed on the surface of tested steel member.
Beneficial effect of the present invention mainly shows: 1, can singly only use, also can multichannel use simultaneously, can realize multimetering; 2, rational in infrastructure, easy for installation; 3, easy to use; 4, connect reliably.

(5) embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 4～Fig. 8, a kind of fast multi-path strain measuring device, comprise the strain transducer 1, sensor connecting line 5, the strain gauge 8 that are connected with tested member, described strain transducer 1 is connected with sensor connecting line 5, described strain gauge means also comprises the push-in connector 9 of multichannel, described sensor connecting line 5 is connected with the push-in connector 9 of described multichannel, and the push-in connector 9 of described multichannel is connected with strain gauge 8.
Described strain transducer 1 is installed on the magnetic suction base 6, and described magnetic suction base 6 is provided with the surface of contact 7 that mates with the profile of tested steel member.
Described magnetic suction base 6 is provided with the circular arc surface of contact that cooperates with the profile of cylindrical steel member.Certain, the surface of contact 7 of magnetic suction base also can be other shapes such as arch, mates as long as satisfy with the profile of tested steel member.
The concrete course of work of present embodiment is: during use, during use, only need magnetic suction base 6 is adsorbed on the surface of tested steel member, be connected by the push-in connector 9 of connecting line 5 and multichannel, just can measure easily; Be connected with strain gauge 8 by the push-in web member 10 of multichannel, can sample, store and pursue the strain value that the road shows each channel sensor simultaneously.Magnetic suction base strain transducer can be used in material stretch test machine separately, substitutes folder formula strain extensometer commonly used now; Also can with through the supporting use of particular design strain gauge means.
