Abstract
The invention discloses a torque sensor, which includes a pedestal, a strain beam, a torsional force head, strain gauges, a cover casing and fixing bolts. The strain beam is vertically welded to the pedestal. The upper end of the strain beam is welded to the torsional force head. The four strain gauges are fixedly arranged on the strain beam. A Wheatstone bridge is formed among the four strain gauges. The pedestal is welded to the cover casing. The cover casing covers the strain beam. The two bolts are vertically mounted on the pedestal through a threaded connection mode. The advantages are that the torque sensor is simple in structure, has a good measuring effect, etc.
Description
Technical field
The present invention relates to a kind of torque sensor, be applied to mechanical torque fields of measurement.
Background technology
Along with the continuous progress of science and technology, torque sensor has been widely used in the measurement to various mechanical part torsional forces, but the complicated structure of existing torque sensor, and cost is higher, therefore be not suitable for extensively promoting the use of, and the measurement effect of existing torque sensor is bad.
Summary of the invention
For solving the defect of prior art, the invention discloses the torque sensor that a kind of structure is simple, measurement effect is good.
The invention discloses a kind of torque sensor, comprise: base, strain beam, torsion head, strainometer, case, set bolt, described base vertically welds a strain beam, a torsion head is welded in the upper end of described strain beam, described strain beam sets firmly four stress gauges, and form Wheatstone bridge between four stress gauges, described base welds a case, strain beam covers by described case, and the mode that described base is threaded connection vertically installs two set bolts.
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 torque sensor of the present invention.
Wherein: 1-base; 2-strain beam; 3-torsion head; 4-strainometer; 5-case; 6-set bolt.
Embodiment
As shown in Figure 1, the invention discloses a kind of torque sensor, comprise: base 1, strain beam 2, torsion head 3, strainometer 4, case 5, set bolt 6, described base 1 vertically welds a strain beam 2, a torsion head 3 is welded in the upper end of described strain beam 2, described strain beam 2 sets firmly four stress gauges 4, and form Wheatstone bridge between four stress gauges 4, described base 1 welds a case 5, strain beam 2 covers by described case 5, and the mode that described base 1 is threaded connection vertically installs two set bolts 6.
The present invention implements like this: fixed on the table by base 1 by set bolt 6, to need the jacket casing of the machinery measured on torsion head 3, apply a moment of torsion to machinery, the sleeve of machinery applies a torsion can to torsion head 3, torsion head 3 applies a torsion to strain beam 2, now can there is deformation in strain beam 2, the deformation that strain beam 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, measurement effect is relatively good, and torque 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.
