Abstract
The utility model relates to a sensor, in particular to a double-shear beam cylinder type sensor, which aims at resolving the technical problem that weighing accuracy of an existing double-shear beam sensor is not sufficient and processing is inconvenient and provides the double-shear beam cylinder type sensor capable of more effectively transmitting pressure to strain foils and thereby improving the weighing accuracy and also being convenient to process. The double-shear beam cylinder type sensor comprises an elastic body, the strain foils and a cable, wherein the cable is connected to one end of the elastic body which is cylindrical, a plurality of recessions are disposed on the outer lateral wall of the elastic body, the strain foils cling to the inside of the recessions, and bolt holes parallel to the strain foils are disposed respectively at both ends of the elastic body.
Description
Technical field
The utility model relates to a kind of sensor, more specifically to a kind of double-shear beam column type sensor.
Background technology
At present, the double-shear beam sensor is widely used in all kinds of electronic-weighing equipment such as electronic vehicle weighing apparatus, vapour inspection line, track scale as LOAD CELLS, and the most employing of existing double-shear beam sensor is the two-end fixed beam structure; Because the border rigidity of this structural requirement sensor is big, make that therefore sensor construction is complicated, build also increases thereupon; And then make installation inconvenient; Do not meet now the miniaturization of weighing-appliance and integrated requirement, the Chinese patent notification number is CN201196586Y, and the day for announcing is that the utility model name on February 18th, 2009 is called double-shear beam type LOAD CELLS; Include base, be connected in elastic body on the base, be attached to strainometer on the elastic body, be positioned at the steel ball of elastic body upper end and prevent the pressure bearing head on steel ball; Said elastic body is through preventing two cylinders on said base as support, and elastic body is connected with base through bolt and elastic washer, and it is parallel that the axis of said cylinder and elastic body get width; Owing to adopted the supporting construction of both-end tube; Reduced the height of sensor, made it have shock proof ability, but the weighing precision of LOAD CELLS is still accurate inadequately; And increased cylinder as support, increased manufacture difficulty and cost.
Summary of the invention
The purpose of the utility model is that to overcome double-shear beam sensor weighing precision not enough, the technical barrier that processing is inconvenient, and providing a kind of can more effectively pass to pressure foil gauge and then improve weighing precision, and double-shear beam column type sensor easy to process.
The utility model solves through following technical proposals: a kind of double-shear beam column type sensor; Comprise elastic body, foil gauge and cable; Described cable is connected with elastic body one end, and described elastic body is cylindric, and the elastic body lateral wall is provided with several depressions; Described foil gauge is attached in the depression, and the elastic body two ends are respectively equipped with the bolt hole parallel with foil gauge.Cylindrical elastic body makes the pressure that receives pass to foil gauge more uniformly, simultaneously foil gauge is attached in the depression, makes the pressure that receives on the elastic body more directly effectively pass to foil gauge, and then improves weighing precision.
As preferably, described elastic body middle has annular slot, and described depression is positioned at the annular slot both sides.Annular slot is elastomeric stress point, makes at the foil gauge of annular slot both sides and better accepts the pressure that elastic body transmits, and improves weighing precision.
As preferably, describedly be depressed with four, respectively there are two depressions the annular slot both sides, and are symmetrical set about annular slot.Make that the foil gauge that is attached in the depression is more effective accepts the pressure that elastic body receives.
As preferably, be plane with depression elastic body lateral wall on every side around the bolt hole two-port.Make and elastic body is installed and foil gauge is installed convenient through bolt hole.
As preferably, described cable is connected with elastic body through water joint.Water joint can play waterproof effect.
Therefore, a kind of double-shear beam column type sensor of the utility model possesses following beneficial effect, 1, simple in structure; Processing, easy for installation, 2, cylindrical elastic body makes the pressure that receives pass to foil gauge more uniformly; Foil gauge is positioned at depression simultaneously; And be positioned near the elastic body stress point, make foil gauge more directly effectively accept elastomeric pressure, and then improve weighing precision.

Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: like Fig. 1, shown in Figure 2, a kind of double-shear beam column type sensor comprises elastic body 1, foil gauge 3 and cable 2; Elastic body 1 is cylindric (as shown in Figure 3), and the stressed back of elastic body 1 pressure is transmitted more uniformly, has annular slot 6 in the middle of elastic body 1; Annular slot 6 takes the shape of the letter U, and annular slot 6 both sides respectively have two depressions, and is symmetrical set about annular slot 6; Depression is round shape, in each depression, all is pasted with a foil gauge 3, and then foil gauge 3 is embedded in the elastic body 1; Annular slot 6 makes pressure more directly effectively pass to foil gauge 3 as stress point simultaneously.Right ends middle at elastic body 1 has a bolt hole 5, and the direction of bolt hole 5 is parallel with the direction of foil gauge 3, is plane with depression elastic body 1 lateral wall on every side around bolt hole 5 two-port.Cable 2 is connected with an end of elastic body 1 through water joint 4, and water joint 4 can play waterproof, grease proofing effect.
Weight exert pressure with elastic body 1 on annular slot 6 places; Because elastic body 1 has deformability, deformation takes place, and then make 3 of strains that are attached in the depression also receive deformation pressure; Foil gauge 3 just can draw weight of heavy through converting pressure into electric weight through calculating electric weight.And foil gauge is near more apart from breach, and the amplitude of elastic body deformation is big more, and the deformation pressure that foil gauge receives is just big more, and weighing precision is just accurate more.
