Toward being only designed to one, such as Chinese invention patent " the double component strain of a kind of tension-torsion that number of patent application is 201310693936.2
Sensor ", this sensor is two flange arrangement, is designed as four rod structures, induced torque strain and axial force between two flanges
The foil gauge of strain is pasted onto in the post plane of above-mentioned four rod structures simultaneously, due to post after elastomer is produced deformation by axial force
The transversal effect (horizontally and vertically direction strain) of formula structure, brings linearity error relatively big, and pole structure cannot be by axle
Be made less to the specified range value of force direction, and the specified range in axial force direction do little after, due to four rod structure intensity fall
The low intensity inherently reducing torque direction causes the specified range of torque direction to reduce, when elastomer is by axial force, torque combinations
Owing to two groups of paster regions are in same post plane after deformation, add and interfere error.It is thus desirable to existing structure is entered
Row improves, and designs one and can measure axial force and moment of torsion output simultaneously, interferes error little, and can be by the axle of sensor
It is made less compound sensor to the specified range of force direction.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, survey for the above-mentioned state of the art
Accuracy of measurement is high and the specified range in axial force direction of sensor can be made less measurement axial force and the composite sensing of moment of torsion
Device.
This utility model solves the technical scheme that used of above-mentioned technical problem: a kind of measure answering of axial force and moment of torsion
Close sensor, the upper flange including elastomer, being located at the upper and lower two ends of elastomer and lower flange, it is characterised in that: described elastomer
The most axially form as detection torque direction strain region cylindricality barrel, cylindricality barrel be positioned at upper flange underface,
And with the central coaxial of upper flange Yu lower flange, for pasting the moment of torsion strain gauge adhesion measuring torque signal at cylindricality barrel
On, it is provided with the spoke architecture in the strain region as detection axial force in lower flange, for measuring the axial of axial direction signal
Stress-strain sheet is pasted onto in spoke architecture.
As improvement, described upper flange and lower flange are disc-shaped structure, and cylindricality barrel is cylindrical, and moment of torsion foil gauge is
4, uniform intervals hoop is pasted onto in the middle part outside wall surface of cylindricality barrel respectively.
As improvement, described spoke architecture and lower flange, for being arranged concentrically, are evenly distributed with in crosswise in spoke architecture
Four spokes, axial force foil gauge is 4, is respectively adhered on four spokes.
Improving, the upper end center position of described upper flange and the lower center position of lower flange are respectively provided with sensing again

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in figures 1-4, a kind of compound sensor measuring axial force and moment of torsion, including elastomer 1, it is located at elastomer 1
Up and down the upper flange 2 at two ends and lower flange 3, upper flange 1 and lower flange 2 are symmetrically arranged for disc-shaped structure, upper flange 2 and under
The edge of flange 3 is respectively equipped with in multiple connecting screw hole 21 and 31, the upper end center position of upper flange 2 and the lower end of lower flange 3
Heart position is respectively provided with the circular counter bore 22 and 32 of radial direction location when sensor is installed, axial molding in elastomer 1
Have as detection torque direction strain region cylindricality barrel 4, cylindricality barrel 4 be cylinder, be positioned at upper flange 2 just under
Side, cylindricality barrel 4 and upper flange 2, the central coaxial of lower flange 3, be 4 for pasting the moment of torsion foil gauge 6 measuring torque signal
Individual, uniform intervals hoop is pasted onto in the middle part outside wall surface of cylindricality barrel 4 respectively；Spoke architecture 5, spoke it is provided with in lower flange 3
