Abstract

The utility model provides a double-range torque sensor which is used for solving problems of troublesome operation, low working efficiency, and easy shedding of locating pins of a conventional torque sensor. The sensor comprises a sensor body which comprises a big flange and a small flange. An elastic body is disposed between the big flange and the small flange. The big flange is connected with the small flange through the elastic body. A side surface of the big flange is provided with two or more locating pins. The exterior of the sensor body is provided with a protective cover body. A resistance strain gauge is pasted on the elastic body and used for forming a Wheatstone bridge. The elastic body and the locating pins are respectively made of 17-4PH stainless steel materials.

Description

Double-range torque sensor
Technical field
The utility model relates to a kind of torque sensor, relates in particular to a kind of double-range torque sensor.
Background technology
Torque sensor is the critical component in torque measurement and calibrating installation, torque sensor is widely used in the detection of the rotary power equipment output torques such as motor, generator, and the detection of the moment of torsion such as blower fan, water pump, torque spanner, traditional torque sensor is that single range is measured, in practical operation, need to complete different tests by the sensor of the different ranges of continuous replacing, troublesome poeration, inefficiency; Torque sensor is provided with the register pin for locating, and the register pin on traditional torque sensor is very easy to come off, thereby easily occurs measurement problem.
Utility model content
The deficiency that the utility model exists for prior art, provides a kind of double-range torque sensor, has solved traditional torque sensor troublesome poeration, inefficiency and register pin and has held caducous problem.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of double-range torque sensor; comprise sensor body; described sensor body comprises large flange and little flange; between described large flange and described little flange, be provided with an elastic body; described large flange is connected by described elastic body with described little flange; described large flange side is provided with two or more register pins, and described sensor body outside is also provided with a protection cover body.
Further, on described elastic body, be pasted with for forming the strain ga(u)ge of Wheatstone bridge.
Further, described elastic body and register pin are 17-4PH stainless steel.
The beneficial effects of the utility model are: the utility model adopts double-range, can on same sensor, can complete online the measurement of large small-range simultaneously, and large small-range is poor reaches 10-30 doubly, facilitates practical operation, has improved work efficiency; In sensor body appearance, be provided with protection cover body, effectively prevent register pin displacement, guaranteed the quality of sensor.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model sensor body;
Fig. 3 is the structural representation of the utility model protection cover body.
Wherein, 1, large flange; 2, little flange; 3, elastic body; 4, register pin; 5, protection cover body; 6, strain ga(u)ge.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of double-range torque sensor, comprise sensor body, described sensor body comprises large flange 1 and little flange 2, between described large flange 1 and described little flange 2, be provided with an elastic body 3, described large flange 1 is connected by described elastic body 3 with described little flange 2, and described large flange 1 side is provided with two or more register pin 4.
During work, large flange 1 in sensor body is fixed by the table top of bolt and equipment, the test lead of little flange 2 is connected with test specimen, when test specimen produces swing offset, sensor body also produces swing offset thereupon, at this moment the large flange 1 of sensor body and the little flange 2 generation displacement of simultaneously working, when torsional forces is enlarged to small-range on little flange 2 at full capacity time, register pin 4 will play position-limiting action, the small-range work of little flange 2 tests completes, now, the work of large flange 1 test wide range still can continue, thereby realized the test job that completes the range that varies in size on a sensor.
Described sensor body outside is also provided with a protection cover body 5.When sensor body is when working; owing to there being moment of torsion; when moment of torsion is excessive; register pin 4 can play positioning action; now be very easy to cause register pin 4 to occur loosening, thereby cause measuring inaccurate, in the outside of sensor body, add a protection cover body 5; can effectively stop register pin 4 to occur loosening, thereby improve the accuracy of measuring.
On described elastic body 3, be pasted with for forming the strain ga(u)ge 6 of Wheatstone bridge; Driving voltage on Wheatstone bridge, under the effect of moment of torsion, elastic body 3 produces distortion, strain ga(u)ge 6 variations that have a resistance thus, thus it is uneven that Wheatstone bridge is occurred, the voltage signal that electric bridge output and moment of torsion are linear.
Described elastic body 3 and register pin 4 are 17-4PH stainless steel.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
