Abstract
One kind splitting cartridge type torque sensor, including splits barrel structure, detection device, rigid section and connecting interface；It splits barrel structure and is the cylindrical shape of both ends open, and be provided in the axial direction with the through slot isometric with cylinder on cylinder side wall；Detection device is arranged on through slot, and the cylinder side wall of detection device connection through slot two sides；The both ends for splitting barrel structure pass through rigid section respectively and are fixedly connected with connecting interface.The present invention can greatly improve measurement sensitivity using barrel structure is split to the enlarge-effect of torsional deflection under the premise of not sacrificing sensor torsion stiffness itself, access smaller to the stiffness effect of system after measurand.
Description
Technical field
The invention belongs to sensor technical field, in particular to one kind splits cartridge type torque sensor.
Background technique
Torque measurement is various engineering goods (robot, internal combustion engine, blower etc.) exploitation, quality inspection, optimal control, work
The essential content such as condition monitoring and fault diagnosis.Strain-type torque sensor is most widely used a kind of torque sensing
Device: by pasting Strain Meter Set on elastic shaft at measuring bridge (Huygens's electric bridge), when elastic shaft is generated small change by torque
Bridge resistance is caused to change after shape, the change transitions of strain bridge resistance are the variation of electric signal to realize torque measurement.
The characteristics of foil gauge torque sensor is that measurement range is big, cheap, convenient for selection etc..
In order to improve measurement sensitivity, the amplitude of strain can be increased by reducing the torsion stiffness of sensor itself,
But the rigidity that can reduce system entirety is done so, what this did not allowed often.Therefore, before guaranteeing sensor high rigidity
Raising measurement sensitivity is put, is the difficult point of torque sensor.
Summary of the invention
The one kind that is designed to provide of invention splits cartridge type torque sensor, to solve the above problems.
To achieve the above object, the invention adopts the following technical scheme:
One kind splitting cartridge type torque sensor, including splits barrel structure, detection device, rigid section and connecting interface；Split barrel structure
For the cylindrical shape of both ends open, and through slot is provided in the axial direction on cylinder side wall；Detection device is arranged on through slot, and detects dress
Set the cylinder side wall of connection through slot two sides；The both ends for splitting barrel structure pass through rigid section respectively and are fixedly connected with connecting interface.
Further, connecting interface includes connection ring and fixed plate；One end of connection ring is fixedly connected on shape in fixed plate
At connecting interface, several bolts hole are provided in fixed plate.
Further, through slot is left a blank or packing ratio splits the small material of barrel structure elasticity modulus of materials.
Further, one end of rigid section is fixedly connected with barrel structure end circular loop is split, the company of the other end and connecting interface
Ring end is connect to be fixedly connected；Connecting interface with measurand for being connected.
Further, detection device is strain-type, condenser type or eddy current sensor；Detection device and through slot two sides
Cylinder side wall is fixedly connected.
Further, detection device is connected with amplifier, for will test signal enhanced processing.
Compared with prior art, the present invention has following technical effect:
The present invention can not sacrifice sensor torsion stiffness itself using barrel structure is split to the enlarge-effect of torsional deflection
Under the premise of greatly improve measurement sensitivity, access smaller to the stiffness effect of system after measurand；
The present invention in addition to detection device, sensor body structure can whole monolithic processing, structure is simple, without assembly.
