Description
Technical field
A kind of load deformation apparatus for automatically measuring is the utility model is related to, is particularly used for determining butterfly spring load and change
The self-operated measuring unit of shape.
Background technology
Butterfly spring is a kind of flexible member, is deformed as normal spiral spring, during work under axial load.
The mechanical property of generally measure butterfly spring is by specifying the load under deflection to determine, measure butterfly spring is specifying deformation
Load under amount is the Main Means for detecting butterfly spring mechanical property.Because butterfly spring is rigidly larger, deflection during work
It is smaller, the accuracy of load measurements is determined to the measurement accuracy of its deflection.
The deformation measurement method that past is commonly used has displacement-measurement procedure, kind of calliper method, dial gauge mensuration, amesdial measurement
Method.Various measuring methods are all axially loaded to butterfly spring progress using universal testing machine, and wherein displacement-measurement procedure makes
The deflection of butterfly spring is used as by the use of testing machine crosshead displacement；Kind of calliper method is with two bearing-surfaces above and below slide calliper rule manual measurement
Between deflection of the distance change as butterfly spring；Dial gauge method amesdial method is by a special loading device to butterfly
Spring loads, the deflection of disc spring is measured with dial gauge or amesdial.In the above method, displacement-measurement procedure is mistakenly by testing machine
Deflection of the crossbeam as butterfly spring, test result mistake；Kind of calliper method is attempted with slide calliper rule direct measurement butterfly spring
Deflection is unpractical, because dynamic realtime process during loading, load and deformation manually observe slide calliper rule in constantly change
The deflection specified can not be accurately found, thus measuring accuracy is extremely low；Dial gauge method and amesdial method precision are slightly higher, but need
Reading, testing efficiency are very low simultaneously on testing machine and dial gauge or amesdial.There is presently no use digital sensing completely
The method of device determines the device of butterfly spring deflection and load simultaneously.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, provide a kind of side for using digital sensor completely
Method automatically determines the device of butterfly spring deflection and load, and loading and measurement are realized on electronic universal tester, is remembered simultaneously
Deformation and the load data of butterfly spring are recorded, draws butterfly spring load displacement curve, is read automatically from curve and specifies deformation
Under load, device use load sensor and deformation-sensor can be better than ± 1% relative error.
What be the utility model is related to is used to determine the self-operated measuring unit of butterfly spring load and deformation, by base 9,4
Column 3, upper backup pad 2, loading post 1 are formed, and the wherein center of upper backup pad 2 is provided with high-precision circular hole, and its aperture is slightly larger than loading
0.02~0.04mm of diameter of post 1, support and guide effect can be played to loading post 1.It is provided with and can adjusts up and down on loading post 1
The support 4 of position, upper measurement bar 5 vertically downward is fixed with by locking nut 51 on support 4, and the opposite side of support 4 is provided with
Groove, support 4 can be locked on loading post 1 by wing nut bolt group 41, so that it is guaranteed that support 4 and installing thereon upper
Measurement bar 5 and loading post 1 are rigidly attached and are integrated.Lower measurement bar 7 vertically upward, upper measurement are mounted with base 9
Bar 5 and lower measurement bar 7 on same vertical axis, extended on deformation-sensor 6 arm 61 and under extend arm 62 by its each
The edge of a knife of end is separately fixed in measurement bar 5 and lower measurement bar 7.
The self-operated measuring unit of the present utility model for being used to determine butterfly spring load and deformation, using 4 pillar constructions, really
Protecting whole framework has enough rigidity and stability, and upper backup pad is made by cold work die steel, be heat-treated to 60HRC with
On, its center is provided with high-precision guide support hole；Loading post is made by nitrided steel, through being adjusted to more than 40HRC hardness,
Then Ra0.8mm surfaces extra coarse degree is worked into, then it is big through Nitrizing Treatment to more than case hardness 1000HV, effective case depth
In 1mm, then the face of cylinder is polished, to reduce the friction between loading post and upper backup pad；Base integrally uses nitriding
Steel is made, and through being adjusted to more than 40HRC hardness, is then worked into Ra0.8mm surfaces extra coarse degree, then arrive through Nitrizing Treatment
More than case hardness 1000HV, effective case depth are more than 1mm.
The self-operated measuring unit of the present utility model for being used to determine butterfly spring load and deformation, system rigidity is big, with butterfly
The loading post and base body hardness that shape spring directly contacts are high, and surface is after Nitrizing Treatment, and hardness is far above butterfly spring
Hardness, it ensure that device is nearly free from deformation, the deflection measured in measurement process by deformation-sensor is by butterfly spring
Self-deformation and produce.As long as it ensure that the precision of testing machine force snesor and the precision of deformation-sensor, you can ensure disc spring
Specify the measurement accuracy of the lower load of deformation.Deformation-sensor and force snesor are accessed to the controller of testing machine simultaneously simultaneously, just
The data of the two passages can be gathered simultaneously, draw curve, read result of the test, this process is completely by testing machine software control
System and execution, it is not necessary to think to intervene.After the device of the invention, experimenter only needs to install sample, and installation deformation passes
Sensor (when measuring for the first time), then operate software and start experiment after experiment terminates automatic unloading, remove butterfly bullet Huang, examination
Test result to be directly displayed on software, the degree of accuracy of test efficiency and result can greatly improve.
