Abstract
The invention discloses a tension sensor, which includes an upper bearing sleeve, a stain sleeve, a lower bearing sleeve and strain gauges. The upper bearing sleeve is welded to the upper end of the strain sleeve, and the lower end of the strain sleeve is welded to the lower bearing sleeve. The four strain gauges are fixedly arranged on the sleeve wall of the strain sleeve. A Wheatstone bridge is formed among the four strain gauges. The advantages are that the tension sensor is simple in structure, has a good measuring effect, etc.
Description
Technical field
The present invention relates to a kind of pulling force sensor, be applied to axle tension measurement field.
Background technology
On vehicle testing line, need to detect automobile top split axle and can bear much pulling force, the main pulling force of pulling force sensor to axle that adopt is measured at present, but the complicated structure of existing pulling force sensor, cost is higher, is not suitable for extensively promoting the use of, and existing pulling force sensor is in the process measured, stressed not steady, thus the defect causing measurement effect bad.
Summary of the invention
For solving the defect of prior art, the invention discloses the pulling force sensor that a kind of structure is simple, measurement effect is good.
The invention discloses a kind of pulling force sensor, comprise: upper pressure-bearing sleeve, strain sleeve, lower pressure-bearing sleeve, strainometer, described upper pressure-bearing sleeve weld is in strain sleeve upper end, a lower pressure-bearing sleeve is welded in the lower end of described strain sleeve, be installed with four stress gauges in the sleeve wall of described strain sleeve, and form Wheatstone bridge between four stress gauges.
Owing to adopting technique scheme, the present invention has following advantageous benefits:
1, structure is simple;
2, measurement effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pulling force sensor of the present invention;
Fig. 2 is the using state schematic diagram of a kind of pulling force sensor of the present invention.
Wherein: the upper pressure-bearing sleeve of 1-; 2-strains sleeve; Pressure-bearing sleeve under 3-; 4-strainometer.
Embodiment
As shown in Figure 1-2, the invention discloses a kind of pulling force sensor, comprise: upper pressure-bearing sleeve 1, strain sleeve 2, lower pressure-bearing sleeve 3, strainometer 4, described upper pressure-bearing sleeve 1 is welded on strain sleeve 2 upper end, a lower pressure-bearing sleeve 3 is welded in the lower end of described strain sleeve 2, be installed with four stress gauges 4 in the sleeve wall of described strain sleeve 2, and form Wheatstone bridge between four stress gauges 4.
The present invention implements like this: rotate in the upper end of axle and tighten a nut, the lower end of axle is inserted into through upper pressure-bearing sleeve 1 and strains in sleeve 2 and stretch out through lower pressure-bearing sleeve 3, such nut is stuck on the upper surface of pressure-bearing sleeve 1, processing staff only need by pulling the lower end of axle, can be exerted pressure to upper pressure-bearing sleeve 1 by nut in the upper end of axle, upper pressure-bearing sleeve 1 can be exerted pressure to strain sleeve 2, can deformation be there is in strain sleeve 2, the deformation that strain sleeve 2 occurs is converted to the change of resistance by such strainometer 4, the physical quantity being about to sense is converted to electric signal, then electric signal is flowed to outside measuring instrument by wire by strainometer 4, due to stressed more steady in the process measured, therefore measurement effect is relatively good, and pulling force sensor structure of the present invention is simple, cost is low, be suitable for extensively promoting the use of.
Above embodiment only in order to the present invention is described and and unrestricted technical scheme described in the invention; Therefore, although this instructions with reference to each above-mentioned embodiment to present invention has been detailed description, those of ordinary skill in the art should be appreciated that and still can modify to the present invention or equivalent to replace; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed in right of the present invention.
Claims (1)
1. a pulling force sensor, comprise: upper pressure-bearing sleeve, strain sleeve, lower pressure-bearing sleeve, strainometer, it is characterized in that: described upper pressure-bearing sleeve weld is in strain sleeve upper end, a lower pressure-bearing sleeve is welded in the lower end of described strain sleeve, be installed with four stress gauges in the sleeve wall of described strain sleeve, and form Wheatstone bridge between four stress gauges.
