Abstract
The utility model discloses a cross-shaped structure bridge-type sensor, which relates to a sensor, and comprises an elastic body (1) and a strain blind hole (3). The strain blind hole (3) is arranged on the elastic body (1); a strain foil (6) is arranged in the strain blind hole (3); a gasket cement (5) is covered on the strain blind hole (3), and a cover plate (4) is sealed on the strain blind hole (3); the elastic body (1) is a monoblock forging piece; the upper part of the elastic body (1) is provided with a plurality of cross-shaped beams (2) verticalto each other; the strain blind hole (3) is arranged on the end beam of the cross-shaped beams (2). The elastic body is made to a double-shear beam cross-shaped structure vertical to each other so as to effectively improve the deflection of a loading point in an X-Y plane; compared with the traditional bridge-type sensor, the cross-shaped structure bridge-type sensor has better anti-deviated load performance. Additionally, as the overload protection structure is increased and the bridge-type sensor has compact structure and small midway deflection, compared with the composite construction of the traditional bridge-type sensor, the cross-shaped structure bridge-type sensor has stronger overload protection capability.
Description
Technical field
The utility model relates to a kind of sensor, specifically is a kind of bridge type magnetic sensor of decussate texture.
Background technology
The bridge type magnetic sensor structure of two supports in the prior art, I-shaped cross-section commonly used beam is as elastic body 1 structure, elastic body 1 is provided with strain blind hole 3, and foil gauge is posted in the two sides of strain blind hole 3, and elastic body 1 is fixed together (showing as Fig. 7) by the screw and the base at two ends.By pressure head and steel ball 15 power is delivered on the elastic body 1 when stressed, the foil gauge during elastic body 1 stress deformation in the strain blind hole 3 bears shear stress.This structure shearing is a constant along the strain beam length direction, and the output of sensor and the moment of flexure of beam are irrelevant, and is only proportional with shear stress, thereby output is insensitive to load(ing) point variation along its length.But it is, bigger at Width load(ing) point variable effect, therefore relatively poor at the lateral force resistance of width direction sensors because Width is narrower.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this utility model provides a kind of cruciform bridge type magnetic sensor, and it improves the anti-side direction ability of sensor four direction by improving existing elastomer structure.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of cruciform bridge type magnetic sensor, comprise elastic body and strain blind hole, the strain blind hole is arranged on the elastic body, be provided with foil gauge in the strain blind hole, and on the strain blind hole, cover fluid sealant and cover plate for sealing, described elastic body is the monoblock forging, and its top is orthogonal cross-bar, and described strain blind hole is arranged on the end carriage of cross-bar.In the above-mentioned technical scheme elastic body is made into orthogonal double-shear beam decussate texture, can effectively improves the skew of load(ing) point in X-Y plane, better anti-bias load ability is arranged than the conventional bridge sensor.
As preferably, described strain blind hole is two, and it is symmetricly set on the end carriage of cross-bar.Two I-shaped strain regions that the strain blind hole forms.
As a kind of mode, the top of above-mentioned cross-bar is provided with loading bench, and loading bench is provided with arc groove, and arc groove is used to carry steel ball.As another kind of mode, can be provided with the circular arc projection on the above-mentioned loading bench, the circular arc projection can be directly stressed.
As preferably, above-mentioned elastomeric bottom is a base plate, and elastic body and base plate are one-piece construction, are provided with the space between base plate and the cross-bar, and are provided with boss at the center of cross-bar, are provided with the gap of overload protection between boss and the base plate.When load surpassed the design permissible value, boss was out of shape downwards and contacts with base plate, played the effect of protection sensor.
As an alternative, above-mentioned elastomeric below is connected with base plate by screw, is provided with the space between base plate and the cross-bar, and is provided with boss at the center of cross-bar, is provided with the gap of overload protection between boss and the base plate.
The utility model is made into orthogonal double-shear beam decussate texture owing to adopt above-mentioned technical scheme with elastic body, can effectively improve the skew of load(ing) point in X-Y plane, than the conventional bridge sensor better anti-bias load ability is arranged.Simultaneously, increase overcurrent protection structure, compact conformation in addition, midway deflection is little, than the unitized construction of conventional bridge sensor stronger overload protection ability is arranged.
