Description
Technical field
The utility model relates to a kind of three beam type attached sensors elastic bodys, especially a kind of elastic body that is used on the adhesion type strain force cell.
Background technology
At present, adhering sensor mainly is that the mode of sensor with welding or bolted is fixed on the measured object, such as the leg of bridge, on the supporting leg of batch can.Reflect its suffered gravity or by dynamometry by the distortion of measuring measured object.Adhesion type strain force cell generally adopts single-spar construction, is made of bearing end, strain beam, solid end, and the stress of mainly measuring the tension and compression direction reflects suffered weight of measured object and strength.Owing to generally be surface attached to measured object, and measured object surface stress complexity, the strain transducer beam is subjected to the influence of moment of flexure, moment of torsion unavoidably, and measuring accuracy is descended greatly, has had a strong impact on the indexs such as linearity, hysteresis, repeatability of sensor.

According to the technical scheme that the utility model provides, described three beam type attached sensors elastic bodys comprise elastomeric body, and an end of described elastomeric body is the bearing end, and the other end is solid Zhi Duan; It is characterized in that: the front and back side at the elastomeric body middle part respectively forms a depressed part, axially parallel along elastomeric body in depressed part is provided with oblong first through hole and second through hole, between first through hole and second through hole, form the strain crossbeam, form the first strain vertical beam and the second strain vertical beam in the both sides of first through hole and second through hole respectively.
Be equipped with screw on described bearing end and the solid Zhi Duan.
The thickness of described depressed part is less than the thickness of elastomeric body.
The width of described depressed part is equal to or less than the width of elastomeric body.

Fig. 3 is the A-A view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1 ~ shown in Figure 3: three beam type attached sensors elastic bodys comprise bearing end 1, the first strain vertical beam 2, strain crossbeam 3, the second strain vertical beam 4, solid end 5, elastomeric body 6, screw 7, first through hole 8, second through hole 9, depressed part 10 etc.
The utility model comprises elastomeric body 6, and an end of described elastomeric body 6 is bearing end 1, and the other end is solid end 5, is equipped with screw 7 on bearing end 1 and solid end 5; Respectively form a depressed part 10 at the front and back of elastomeric body 6 middle side part, axially parallel along elastomeric body 6 in depressed part 10 is provided with oblong first through hole 8 and second through hole 9, between first through hole 8 and second through hole 9, form strain crossbeam 3, form the first strain vertical beam 2 and the second strain vertical beam 4 in the both sides of first through hole 8 and second through hole 9 respectively;
The thickness of described depressed part 10 is less than the thickness of elastomeric body 6; The width of described depressed part 10 is equal to or less than the width of elastomeric body 6.
Principle of work of the present utility model: the first strain vertical beam 2, the second strain vertical beam 4 and the strain crossbeam 3 common strain regions that constitute sensor, in use, with welding manner or when being fastened on elastomeric body 6 on the measured object with bolt, along with measured object is subjected to power or gravity, bearing end 1 is distortion thereupon also, the first strain vertical beam 2, the second strain vertical beam 4 and strain crossbeam 3 are experienced this distortion, reflect that by electric bridge measured object is subjected to power or gravity.Owing to gravity or by the corresponding change of dynamometry beam all is the tension and compression direction, and two strain vertical beams composite bending modulus minimum on the tension and compression direction, so the shunting of two strain vertical beam counter stresses is very little, and in other directions, two strain vertical beam composite bending modulus are all bigger, can effectively shield moment of flexure and the influence of moment of torsion to measuring on other directions.Thereby provide a kind of non-linear good, hysteresis error is little, good reproducibility, precision height, adaptable adhesion type strain force cell.
