Abstract
The utility model provides a distortion-resistance plate-ring type attached type sensor, concretely an attached type strain force cell sensor and comprising an elastic body, one end of which is a bearing end and the other end is a clamped end; a strain beam is provided between the bearing end and the clamped end; the center of the strain beam is provided with a ring-shaped aperture; an upper part of the bearing end is provided with a first through hole and a lower part of the clamped end is provided with a second through hole; a left side of the strain beam is provided with two parallel grooves and a right side of the strain beam is provided with two grooves completely symmetrical with the left side; planes extended by the grooves are perpendicular to a length direction of the elastic body. The distortion-resistance plate-ring type attached type sensor has the characteristics of a simple and reasonable structure, excellent nonlinearity, small hysteresis error, good repeatability, high precision and strong adaptability.
Description
Technical field
The utility model relates to a kind of anti-twist plate ring type attached sensors, the force cell of adhesion type strain specifically.
Background technology
At present, adhering sensor mainly is to be fixed on the mode of sensor with welding or bolted on the measured object.Such as the leg of bridge, on the supporting leg of batch can.Through distortion its suffered gravity of reflection of measurement measured object or by dynamometry.Adhesion type strain force cell generally adopts single-spar construction, is made up 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.Because generally be surface attached to measured object, and the measured object surface stress is complicated, the strain transducer beam receives the influence of moment of flexure, moment of torsion unavoidably, and measuring accuracy is descended greatly, the indexs such as linearity, hysteresis, repeatability of sensor have been had a strong impact on.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point, provide a kind of non-linear good, hysteresis error is little, good reproducibility, precision high, adaptable adhesion type strain force cell.
According to the technical scheme that the utility model provides, a kind of anti-twist plate ring type attached sensors comprises the elastic body, and said elastic body's one end is the bearing end, and the other end is solid Zhi Duan, between bearing end and solid Zhi Duan, is provided with strain beam; The strain beam center is provided with a looping pit, and top, bearing end is provided with first through hole, Gu an end bottom is provided with second through hole;
At the strain beam upper left side two parallel grooves are set, two grooves that the strain beam right side is provided with and the left side is symmetrical fully,, the plane of being extended of groove is perpendicular to elastic body's length direction.
Said bearing end and/or solid Zhi Duanyu strain beam junction are provided with a ramp pan.
Said ramp pan is the U-shaped ramp pan of band circular arc.
Said groove bearing of trend runs through the side of strain beam, and inside grooves is not communicated with looping pit; Said groove is the U-lag or the square groove of band circular arc.
The utlity model has following advantage: the utility model is simple and reasonable for structure; U type groove wherein can filter most of bending, reverse interference; And the pressure on the direction of measurement is delivered on the strain beam, thereby provide a kind of non-linear good, hysteresis error is little, good reproducibility, precision high, adaptable adhesion type strain force cell.
