Description
Technical field
This utility model relates to a kind of pressure plate ring type sensor, particularly to be that one is arranged on bearing up-down force portion
Between part, installed by ring flange form and connect, pull to the sensor of power or pressure for detection.
Background technology
In industrial control process, the commonly used ring flange of connection between parts connects, and applies to pull between parts
When power or pressure, this is accomplished by a kind of sensor to detect the size of power, in order to the size of power detects by the equipment that reaches,
Control.
Prior art to the connection between force and the stressed member of equipment generally by point cantact transmit power, to both it
Between power detection be substantially all employing installing force sensor complete.But, currently used force transducer only has pillar, spoke
Formula, cartridge type and shear-beam type, although this several types sensor can be used for detecting the size of power, but they problems of existing
It is:
1. the status requirement of pair stress point is relatively tight, therefore stablizes poor, poor reliability；
2. service life is short；
The biggest, volume is big, and installation requirement is strict, and difficulty is big；
4. offset load resistance is poor.
Utility model content
This utility model is to overcome the weak point existing for prior art, and proposition one connection is installed reliably, performance is steady
Pressure plate ring type sensor fixed, that reliability is high, offset load resistance is strong, to being conveniently mounted to force application part and stress
Between parts, connected by double flange or the simple connection of single ring flange, it is achieved to value of thrust or the accurate detection of force value.
This utility model adopts the following technical scheme that for solving above technical problem
The feature of this utility model a kind of pressure plate ring type sensor is to include: strain ga(u)ge, rosette, inner flange
Dish, outward flange dish, belt stress groove；
Nested inside at described outward flange dish has described inner flange；Set between described outward flange dish and inner flange
It is equipped with described belt stress groove；It is pasted with strain ga(u)ge in described belt stress groove；
The outside of described outward flange dish is provided with described rosette；
It is connected with stressed member by outer bolt hole thereon with described outward flange dish, with described inner flange by it
On Inner bolt holes be connected with force application part, and obtain between described force application part and stressed member with described strain ga(u)ge
The power that pulls to or pressure and by described rosette export the signal of telecommunication, thus formed described in pull to power or pressure detection knot
Structure.
The feature of pressure plate ring type sensor described in the utility model lies also in:
Described strain ga(u)ge forms wheatstone bridge configuration in described belt stress groove.
Described pressure plate ring type sensor with can be to threaded or sleeve between force application part with stressed member
Connect.
Compared with the prior art, this utility model has the beneficial effect that:
This utility model sensor height is low, and volume is little, the same just as pad, can install easily with screw or bolt
Ring flange in the force side of equipment and the ring flange of force side, or between stressed member, and the two of sensor faces and phase
Closing parts and form close contact, the most firm, therefore this sensor is not only hardly damaged, and service life is long, and anti-side is to anti-
Unbalance loading ability is strong, and sensor reliability is high, stable performance, is effectively guaranteed the accurate detection of value of thrust or force value.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
In the present embodiment, as it is shown in figure 1, a kind of pressure plate ring type sensor 5 includes: strain ga(u)ge 2, rosette 4,
Inner flange 6, outward flange dish 7, belt stress groove 10；
The nested inside of ring flange 7 has inner flange 6 outside；Inner flange 6 near center, outward flange dish 7 outside, far
From center, it is respectively used to force application part 9 and stressed member 8 are installed, is provided with annular between ring flange 7 and inner flange 6 outside
Stress groove 10, thus constitutes a circular elastomer 1；Strain ga(u)ge 2 it is pasted with in belt stress groove 10；Resistance-strain
Meter 2 forms wheatstone bridge configuration in belt stress groove 10；
The outside of ring flange 7 is provided with rosette 4 outside；
Ring flange 7 is connected with stressed member 8 by outer bolt hole 12 thereon in addition, with inner flange 6 by it
Inner bolt holes 11 be connected with force application part 9, and obtain drawing between force application part 9 and stressed member 8 with strain ga(u)ge 2
Export the signal of telecommunication to power or pressure and by rosette 4, thus form the detection structure pulling to power or pressure.
When apply force value time, inner flange 6 is subjected to displacement at axial direction for outward flange dish 7, two ring flanges it
Between belt stress groove 10 will deform, the size of bulk deformation and the size of exerted forces linearly proportionate relationship, with
Time, the resistance being pasted with strain ga(u)ge 2 in stress groove 10 will change, the Wheatstone bridge consisted of strain gauge 2
Will export the signal of telecommunication with the cable 3 in rosette 4, the size of the signal of telecommunication and the size linearly ratio applying force value are closed
System, finally realizes sensor and accurately detects the size of force value.
In being embodied as, this pressure plare ring type sensor is installed between the force application part of its adaptation and stressed member,
Sensor mounting means connects including, but not limited to ring flange, it is also possible to be threaded installation, it is also possible to be sleeve connection.
