Abstract
A magnetic catching base-type strain sensor comprises a strain sensor; the strain sensor is connected with a sensor connection line which is connected with a testing machine and the strain sensor is installed on the magnetic catching base; the magnetic catching base is equipped with a contact surface which is matched with the shape of the detected steel component. The utility model provides a magnetic catching base-type strain sensor which boasts of convenient installation and use and reliable connection.
Description
(1) technical field
The utility model relates to a kind of strain transducer.
(2) background technology
Existing strain transducer adopts clamp structure, and the folder formula strain extensometer as common employing 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 6 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.Its shortcoming is: 1, the strain transducer of prior art is installed inconvenience; 2, use trouble; 3, connection reliability is poor.
(3) summary of the invention
For installation inconvenience, the use that overcomes existing strain transducer bothers, connects insecure deficiency, the utility model provides a kind of easy for installation, easy to use, reliable magnetic suction base formula strain transducer of connection.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of magnetic suction base formula strain transducer, comprise strain transducer, described strain transducer connects the described strain transducer of sensor connecting line that joins with testing machine and is installed on the magnetic suction base, and described magnetic suction base is provided with the surface of contact that mates with the profile of tested steel member.
As preferred a 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 utility model is: existing strain transducer is fixed on strain transducer on the test specimen by clamping components and spring, inconvenience is installed, as changes different check points, need reinstall, and obviously exists inconvenient.
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,, connecting line is connected with the controller of testing machine gets final product as long as the surface of contact of magnetic suction base is placed on the surface of tested steel member.
The beneficial effects of the utility model mainly show: 1, rational in infrastructure, easy for installation; 2, easy to use; 3, connect reliably.
(4) description of drawings
Fig. 1 is the structural drawing of the strain transducer of prior art.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the sectional view of Fig. 1.
Fig. 4 is the structural drawing of magnetic suction base formula strain transducer.
Fig. 5 is the left view of Fig. 4.
Fig. 6 is the sectional view of Fig. 4.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 4, Fig. 5 and Fig. 6, a kind of magnetic suction base formula strain transducer, comprise strain transducer 1, described strain transducer connects the sensor connecting line 5 described strain transducers 1 that join with testing machine and 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 7 that cooperates with the profile of cylindrical steel member.
During use, only need magnetic suction base 6 is adsorbed on the surface of tested steel member, be connected with testing machine, just can measure easily by connecting line 5.
The magnetic suction base strain transducer of present embodiment 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.
Claims (2)
