Description
Technical field
The present invention relates to sensor technical field, more particularly to a kind of gear division sensor of measurable force feedback.
Background technology
The sensor of measurable force feedback, it is mainly used in measuring the torque that measurand is subject to, traditional mechanics sensor
The mostly sensor such as the pressure of measurement measured body, pulling force, torsion, acceleration and angular speed, it is few that torque is directly surveyed
Measure the sensor calculated.Existing torque sensor can not be applied to gear division equipment because volume is excessively huge, and industrially make
Pressure sensor can only measure an axial direction, it can not be met use demand, so a small size need to be now designed, it is more
Axially, highly sensitive force feedback sensor, to meet the use demand in gear division equipment.
The content of the invention
In view of the shortcomings of the prior art, can be simultaneously the invention provides a kind of gear division sensor of measurable force feedback
The size of the power on multiple axial directions is measured, and the size of torque in all directions is accurately calculated by embedded system.
In order to solve the above problems, the invention provides a kind of gear division sensor of measurable force feedback, the sensor is
Telescopic design, the body of the sensor is divided into the cylinder of inside and the outer barrel of outside, in the inside of the cylinder
Two groups of orthogonal foil gauges are provided with side wall, the bottom of the cylinder is provided with one group of foil gauge, and described three groups should
Become piece to be respectively located in the X-axis, Y-axis and Z axis of cylinder body so that three groups of foil gauges are mutually perpendicular to, and the outer barrel is support
Structure, support foil gauge connected can deformation structure, the supporting construction of three foil gauge present positions is separate, and respectively
It is connected in measurement bar, the supporting construction for reaching to strain on X-axis, Y-axis and the axle of Z axis three using this is independent.
Further improvement is that：Original is calculated by multigroup resistance bridge in the data of foil gauge on three axles
Beginning data, initial data are changed into data signal by a/d converter again, finally by embedded MCU to data signal at
Reason, draws final measurement result.
Further improvement is that：Circuit in the sensor is isolated using radome.
The beneficial effects of the invention are as follows：The gear division sensor of the force feedback of the present invention, can measure multiple axial directions simultaneously
On power size, and accurately calculate by embedded system the size of torque in all directions, adopted on all directions
With miniature foil gauge, solve the problems, such as that the volume of traditional sensors is excessive and can not carry out polyaxial measurement, signal acquisition
Unit uses High-Speed High-Accuracy AD（Modulus）Converter, solve the problems, such as high accuracy and high sampling rate, total is using close
Sealing seals, the problems such as preventing harsh and unforgiving environments from causing sensor degradation.

Fig. 1 is the system flow chart of the present invention.
Fig. 2 is the resistance bridge principle of the present invention.
Embodiment
In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with embodiment, the present embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
This hair embodiment provides a kind of gear division sensor of measurable force feedback, and the sensor is telescopic design, institute
The body for stating sensor is divided into the cylinder of inside and the outer barrel of outside, and two are provided with the internal side wall of the cylinder
The orthogonal foil gauge of group, the bottom of the cylinder are provided with one group of foil gauge, and three groups of foil gauges are respectively positioned at circle
On the X-axis of cylinder body, Y-axis and Z axis so that three groups of foil gauges are mutually perpendicular to, and the outer barrel is supporting construction, support foil gauge
Connected can deformation structure, the supporting construction of three foil gauge present positions is separate, and is connected in measurement bar,
The supporting construction for reaching to strain on X-axis, Y-axis and the axle of Z axis three using this is independent.The data of foil gauge on three axles are equal
Initial data is calculated by multigroup resistance bridge, initial data is changed into data signal by a/d converter again, finally
Data signal is handled by embedded MCU, draws final measurement result.Circuit in the sensor is using screen
Cover is covered to be isolated.
Uniaxially measured to solve conventional pressure sensor, this sensor uses three orthogonal strain chip architectures
Design, and multigroup resistance bridge is used, initial data precision is improved, primary signal amount is changed into number by speed A/D converter
Word signal, data signal is handled finally by embedded MCU, draws final measurement result.
The supporting construction of the present invention is designed using three axle splits, reduce coaxially between in gatherer process between it is mutual
Influence, the strain supporting construction of three axles is independently designed, is individually attached with measurement bar, can suitably be reduced measurement and be missed
Initial data is calculated by resistance bridge in difference, the data of each foil gauge, and all circuit parts are entered by radome
Row isolation, prevents the problem of measured deviation is excessive under harsh working environment.
