Description
A kind of resistance strain type multi-broad force detecting sensor, it can be used for static force or dynamic force measurement; Be used to measure retarding torque, drag torque, pulling force, force of compression, thrust or the like.
At present, single range force detecting sensor of two different ranges of handlebar is connected in series the method that realizes that double-range is measured both at home and abroad, and also the single dynamometry elastomer group of handlebar is assembled into multi-range load cell altogether and realizes multi-range measurement.They are compared with single range force detecting sensor, can realize the measurement of multirange power value, and have improved the measuring accuracy of force cell lower range section to a certain extent.But, adopt the way of combination because these strain-type force sensors all are the dynamometry elastic bodys that has adopted separation structure.Therefore, no matter from the assurance of processing technology, assembling adjusting process, and the raising of sensor accuracy, aspects such as the expansion of range of application all are subjected to certain restriction.When particularly wanting to increase multiple range range number, when just in the gamut scope, thinking to increase sectional number again, structurally will be complicated more, just implement very difficulty.According to existing data, still find no a kind of four quantum force cell.
One of purpose of the present invention provide a kind of simple in structure, shop characteristic good, volume is little, weight is light, the multirange strain-type force sensor that is used to measure retarding torque, drag torque, pulling force, force of compression, thrust of good rigidly, precision height, applied range.Another object of the present invention is to provide one can install and use in vertical direction optional position in the 90 degree scopes of horizontal direction and do not need the multi-range load cell of other auxiliary parts under the above-mentioned condition satisfying.A further object of the present invention provides a kind of each range all starts from scratch, and divides section ground not lose the multi-range load cell of precision measure continuously in the gamut scope.
The present invention is achieved in that force cell except having a load pressure head and chassis, the composite elastic body that also has an I-shaped integrative-structure of radial, it is by the spoke shape body of two different geometrical size up and down, the middle composite elastic body formation that fuses along three's axis with cylinder (solid or hollow).Also can by top be a spoke shape body and following two on same plane, the spoke shape body of concentric, between last lower spokes shape body, constitute along the composite elastic body that their axis is connected as a body with cylinder.Three or four rigidity differences, strain regions that natural frequency is different are arranged respectively on the composite elastic body of these two kinds of versions, therefore, the output of three or four ranges can be arranged.Obviously, get, then can be used as dual-range force detecting sensor and use as long as relax with structural house the technologic part of process.
Be the part that the assisted recombination elastic body bears acting force with joining load pressure head of composite elastic body and chassis among the present invention, form change gap (also being the overload protection gap simultaneously) between multirange with it and composite elastic body simultaneously.The size in these gaps obtains according to the distortion accurate Calculation that composite elastic body is subjected to produce behind the acting force, thereby can be so that two or three strain positions than range obtain range conversion accurately and reliable overload protection immediately after bearing predetermined load.
Composite elastic body relies on wheel hub the one that connects to of each stressed site of action rigidity own, simultaneously because the middle part of wheel hub also is the strain regions of sensor measurement high range power value, so it is designed to the column entity still is that hollow cylinder all has very high strength and stiffness, be enough to keep each strain regions reliability and stability in the course of the work on the composite elastic body.
This sensor can at the corresponding position of each strain regions of composite elastic body adhering resistance strain sheets, and be formed the measuring bridge group, to constitute multiple range strain-type force sensors such as stress, shear stress, pressure (or drawing) stress by bending according to the design needs.
The present invention has adopted the composite elastic body of the I-shaped integrative-structure of radial on version, by elongation, the shortening that makes this this body structure of elastic body, and the increase and decrease of spoke and extend and to obtain a plurality of strain regions, thereby be designed to two, three as required very easily, four-range force cell, and the auxiliary component of having avoided the separation structure elastic body thereupon to bring becomes the 3-4 multiplication many with single elastic body number when the recruitment number of passes.
Second, on performance, because elastic body of the present invention is the I-shaped integrative-structure form of radial, can keep spoke strain beam and pillar strain regions (wheel hub) reliability and stability in the course of the work, make it have the characteristics of stronger anti-bias load and lateral force resistance.The composite elastic body of it and separation structure is compared, support member and connector are paid or assisted to the motion guide rail that need not increase any slip-rolling friction, and it is any irrational, may give support that the key technical indexes such as nonlinearity, hysteresis, nonrepeatability of sensor bring adverse effect, connection, contact plane, contact point etc., the factor that makes sensor produce error significantly reduces.That is to say, can improve the precision of multi-range load cell.
The 3rd, because above-mentioned two factors make multi-range load cell of the present invention to install and use arbitrarily in horizontal direction 90 degree scopes in vertical direction, thereby have enlarged range of application.
The 4th, each range of multi-range load cell of the present invention can be designed to the form of dual output, and therefore the obtaining of data for those disposable measurements that can not repeat provides reliable assurance.Just improved the reliability of sensor.
The 5th, each range of sensor of the present invention is all started from scratch, and can divide section ground to measure continuously in full range.Therefore, it has guaranteed to change in the measuring process of continuous working power value greatly at measuring amplitude, has improved the measuring accuracy of each section in the gamut scope.As everyone knows, in the gamut scope, the range section is got many more, and each sectional measuring accuracy is high more.
The present invention can be applicable to the weighing of various goods and materials, the metering of power value, and in the various dynamic force measurement engineering.
One, the weighing that is used for goods and materials.
For example: in the supply station of materials and equipment or warehouse handling goods weighing all be that metering section with mobile crane, crane is exactly that (or one a group) force cell is added Displaying Meter or printer usually, in handling goods, realized automatic gauge, valuation.Using under the situation of single range sensors, lifting capacity is 20 tons a crane, and it is big just can only to load and unload those weight, the goods that price is low.But the specification of the extensive handling goods in supply station of materials and equipment or warehouse, weight are often quite disperseed, if various kinds, specification, the different goods of weight classes are carried out conveniently, are measured accurately, adopt multi-range load cell to be installed on the crane, just can make things convenient for, rapidly, automatic gauge exactly.In like manner, in departments such as commerce, grain, goods and materials, and industrial sector such as machinery, metallurgy, transportation can be applied.
Two, be used for measurement verification department
For example, 15 tons of second grade standard dynamometers be examine and determine, three or four single range high precision force cells that range does not wait in verification process, will be used in measurement verification department.Because when range reduces, as not using the sensor of corresponding range instead, calibration accuracy will reduce at double.If use one three range or four-range force cell, then can guarantee calibration accuracy, the time of calibration operation and program are shortened greatly, improved work efficiency.
Three, be used for the test of dynamic force
For example: when measuring dynamic force in some engineering, the work of test macro can not optionally be interrupted or repeat, and can not carry out the change of force cell and replace in measuring process.The power of dynamic force is worth time dependent curve shown in Fig. 1 (a).Abscissa is time t(second among the figure); Ordinate is an ergometry value F(ton).If adopt multi-range load cell of the present invention, can in full range, branch Chengdu be zero-based four range: 0-F
1; 0-F
2; 0-F
3; 0-F
4Thereby increase each sectional electrical output signal, reduce the influence of electrical noise, just make each range all can obtain best output signal, improved each sectional measuring accuracy, make test job have under the situation of conversion extension in time carry out the continuous measurement of not losing precision at range.
Fig. 1 (b) is the output characteristic curve of four quantum force cell.Abscissa is an ergometry value F(ton); Ordinate is sensor output value Vs(mV/V).M, N, Q, W are respectively the output characteristic curves of four corresponding ranges.When the power value of lower range section surpasses its range, then become state of saturation, and the maximum amount journey is from 0-F
4Linear in the scope.
According to the needs of actual engineering test, each range of this multi-range load cell all can adopt the form of dual output, and just each range all can connect simultaneously to two test macros.So just can form four ranges are arranged at most, totally eight groups of measuring bridge (R
1～R
8) obtain the output of eight road electric signal, and all can carry out independent measurement respectively, be independent of each other.
