Abstract
The utility model relates to a tray type sensor of resisting lateral force, which is composed of a case, a support block, an elastic body, a bearing seat, a socket and an electric resistance strain gauge. The elastic body is a cantilever with a hole which is formed by crossing a square hole and two circular holes, and the hole is dumbbell-shaped and is arranged in the middle part of the cantilever. The fixed end of the elastic body is fixed on the bearing seat when assembling, and the support block for arranging a tray is arranged on a cantilevered end of the elastic body. The utility model can resist lateral force with high measuring accuracy, the precision can reach 0.03-0.05%, and the low price is only 1/3 of the existing sensor with the same functions.
Description
The utility model belongs to load-sensing unit, relates to a kind of sensor.
Along with the high speed development of The modern industry and improving constantly of instrument and meter for automation level, the use face of sensor is more and more wider, and the sensor of various models is come out one after another.But, have high precision, high stability, strong not the having so far of lateral force resistance less than the 50 micro-journey pellet type sensors that restrain, though the domestic micro-journey sensor that has less than 100 grams, but all belong to semiconductor-type (see " semiconductor sensor spare and product sensor handbook, China National Electronic Devices Industry Corp., in May, 1985), and the outstanding problem of the sensor of semiconductor-type is that poor stability, temperature drift are big, measuring accuracy is low.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of measuring accuracy height, good, the low-cost pellet type lateral force resistance of performance sensor are provided.
The utility model is made up of case, a piece, elastic body, supporting base, base, resistance strain gage.During assembling, supporting base is fixed on an end of base, elastic body is fixed on and forms semi-girder on the supporting base, and a piece of placing pallet is installed on its cantilever end.
In the utility model, elastomeric structure is crucial, and it is a kind of porose semi-girder, and this hole is the hole of special shape, is cut to hand over by a square hole and two circular holes to form, and is " dumbbell " shape, is positioned at the middle part of beam.Elastic body can be made of duralumin or beryllium-bronze or stainless steel.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural drawing of the present utility model; Fig. 2 is elastomeric front view; Fig. 3 is elastomeric vertical view; Fig. 4 is the circuit diagram of resistance strain gage.
As shown in Figure 1, in the present embodiment, sensor is made up of case (1), a piece (2), elastic body (3), supporting base (4), base (5), resistance strain gage (6), elastic body (3) is fixed on supporting base (4) and goes up the formation semi-girder, and a piece (2) of placing pallet is installed on its cantilever end.
As Fig. 2, shown in Figure 3, the hole of a special shape is arranged on the elastic body (3), this Kong Youyi square hole and two circular holes cut to hand over and form, and are " dumbbell " shape, are positioned at the middle part of beam.
During design flexibility body (3), its physical dimension changes along with the variation of transducer range.Range increases, and then the length of elastic body (3) reduces, width, highly increase, the thick increase of hole wall; Range reduces, and then the length of elastic body (3) increases, width, highly reduce, hole wall is thick reduces.In addition, the physical dimension of elastic body (3) is also relevant with manufacturing materials.When range is 50 grams, if adopting duralumin to make its optimum geometry is respectively: 5 millimeters of 20 millimeters of Circularhole diameters, 0.3 millimeter of circular hole portion place minimum wall thickness (MINI W.), the square hole section place wall thickness in 80 millimeters, wide 10 millimeters, high 20.6 millimeters of length, formation " dumbbell " shape hole, the hole heart between the circular hole is apart from 36 millimeters.
The utlity model has following advantage:
1. accuracy of measurement height, precision can reach 3/10000ths～5;
2. but lateral force resistance does not affect accuracies of measurement because of the placement location difference of testee in pallet;
3. low price only is 1/3 of existing congenerous sensor price.
4.50 its sensitivity value of sensor of gram is less than 10 milligrams.
Claims (3)
1, a kind of pellet type lateral force resistance sensor is made up of case (1), a piece (2), elastic body (3), supporting base (4), base (5), resistance strain gage (6), it is characterized in that:
1. elastic body (3) is porose semi-girder, and this Kong Youyi square hole and two circular holes cut to hand over and form, and are " dumbbell " shape, are positioned at the middle part of beam,
2. the stiff end of elastic body (3) is fixed on the supporting base (4), and a piece (2) of placing pallet is installed on the elastomeric cantilever end.
2, sensor according to claim 1 is characterized in that elastic body (3) makes of duralumin or beryllium-bronze or stainless steel.
3, according to claim 1,2 described sensors, the physical dimension that it is characterized in that elastic body (3) is relevant with the range and the manufacturing materials of sensor, when range is 50 grams, if adopt duralumin to make, its optimum geometry is respectively: the hole heart between 80 millimeters, wide 10 millimeters, high 20.6 millimeters of length, 20 millimeters of Circularhole diameters that constitute " dumbbell " shape hole, 0.3 millimeter of circular hole portion place minimum wall thickness (MINI W.), 5 millimeters of square hole section place wall thickness, the circular hole is apart from 36 millimeters.
