Description
Technical field
The utility model relates to a kind of LOAD CELLS, is specifically related to a kind of spoke beam sensor, can be applicable to the electronic weighing appliances such as electronic scales such as bunker scale, truck scale, track scale.
Background technology
LOAD CELLS is a kind of for dynamometry and the sensor of weighing, existing sensor has column structure, Izod and spoke structure, wherein spoke girder structure sensor adopts shear beam structure, there is good natural linear, offset load resistance be strong, precision is high, height of contour is low, the characteristic such as stable easy for installation, widespread use in the electronic scaless such as bunker scale, truck scale, track scale, and in various industrial system, do the Analysis and measurement of power.
Because wheel spoke type sensor is the shear stress utilizing spoke detrusion to produce, but spoke girder structure requires that every root spoke has certain height-width ratio, when highly too low, after causing sensor deformation, recovery capability is poor, cause sensor overall performance poor, this greatly limits the application of spoke girder structure sensor, therefore short size (namely aspect ratio tradition radial reduces about 1/3rd) spoke beam sensor is needed make research and improve.
Through looking into, the existing patent No. is the Chinese utility model patent " a kind of radial force snesor " of CN200620107565.0, comprise wheel hub, rim, wheel spoke and base plate, wheel hub, form strain bore between rim and wheel spoke, described wheel spoke side is provided with foil gauge, and foil gauge top is by the fluid sealant be arranged in strain bore and cover plate for sealing, base plate is provided with pit, be provided with boss bottom rim, boss is plugged in pit, and with pit wringing fit.Strain bore on the elastic body of this sensor runs through, and in order to strengthen stability, the recovery capability improved after sensor deformation also needs to arrange base plate in addition in elastomeric bottom, and not only complex structure, also add processing cost.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple and reasonable spoke beam sensor for the above-mentioned state of the art, it improves the delayed defect of low spoke formula structure LOAD CELLS by elastomer structure adjustment, for the design of short circular configuration LOAD CELLS provides solution, thus whole height is made to reduce about 1/3rd than traditional radial.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of spoke beam sensor, comprise the elastic body of spoke-like, be located at strainometer and cable that elastic body is connected with Wheatstone bridge, it is characterized in that: described elastomeric top is laid with the many spokes be not separated completely, the left and right sides of every root spoke forms uniform strain regions, spoke and elastomeric edge, the nonpenerative strain bore in multiple bottom is formed between elastomeric bottom and center hub, strainometer is arranged in strain bore, be distributed on the strain regions, the left and right sides of every root spoke.
As improvement, described spoke is uniform intervals distribution, and the arc of the both sides of spoke symmetrically indent, strain bore is mounting hole structure.
As improvement, described spoke is four, six, eight or ten of uniform intervals distribution.
As improvement, described strainometer is arranged on the strain regions, the left and right sides of spoke by the mode of pasting.
As improvement, the top of described strain bore is welded with the cover plate for sealing.
Improve, described elastomeric edge has some threaded holes installing location for sensor again.
Improve, described elastomeric edge is provided with the mounting hole that the cable that communicates with strain bore places, and cable is connected with strainometer by data line again.
Compared with prior art, the utility model has the advantage of: spoke is arranged on elastomeric top and is not exclusively separated, make the sealed bottom of the strain bore on elastic body like this, thus greatly strengthen clamped, improve the recovery capability after sensor deformation, there are self sealss bottom hole simultaneously.The utility model is simple and reasonable, manufacture easy to process, and cost is low, the design not being only short circular configuration sensor provides solution, improves overall performance simultaneously, substantially increase the measuring accuracy of low spoke girder structure sensor by adjustment, thus expanded spoke girder structure sensor in the application of various metering industry and applicability, by height reduction about 1/3rd on traditional spoke structure basis, thus make center of gravity lower, use more stable.

Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figures 1 to 3, the spoke beam sensor of the present embodiment, comprise the elastic body 1 of spoke-like, be located at strainometer 3 and cable that elastic body 1 is connected with Wheatstone bridge, be laid with four spokes be not separated completely 2 elastomeric top uniform intervals, can certainly be 6 spokes, 8 spokes or 10 spokes etc., the arc of the left and right sides indent symmetrically of every root spoke 2, form uniform strain regions, the edge of spoke 2 and elastic body 1, the strain bore 11 of the nonpenerative kidney-shaped in multiple bottom is formed between the bottom of elastic body 1 and center hub 4, strainometer 3 is arranged in strain bore 11, be arranged on the strain regions, the left and right sides of every root spoke 2 by the mode of pasting, the upper aperture of strain bore 11 is welded with cover plate 5, play reliable sealing function, four are installed location threaded hole 12 for sensor is offered at the edge uniform intervals of elastic body 1, in addition, laterally be provided with the mounting hole 13 that the power supply cable that communicates with strain bore 11 places at the edge of elastic body 1, cable is connected with strainometer 3 by data line.
The present embodiment is by offering equally distributed many spokes 2 in elastic body 1 upper part, form spoke girder structure, make the strain regions such as the left and right sides formation of every root spoke 2, and by both sides strainometer 3 symmetric patches, finally make strainometer 3 be operated in uniform strain regions., the mounting hole processing spoke 2 due to elastic body 1 is completely not through, thus it is clamped that sensor is strengthened, and effectively improves the recovery capability after sensor deformation.Eventually through the adjustment of above elastic body 1 structure, improve the overall performance of low spoke girder structure sensor, for the sensor design of short circular configuration provides solution.
