Abstract
The utility model discloses a kind of valve oil seal pressure-off force test device, frock in frock and the abjection power being made up of abjection block, connector in lower frock that the device includes being made up of conduit, fixed block, base, the pressing-in force that is made up of pressed-in block, mandrel and connector, the utility model have checking valve oil seal whether because pressing-in force is excessive or abjection power it is too small cause deformation, the rupture of not in place and rubber, it is simple in construction, easy to install the characteristics of.
Description
Technical field
The utility model belongs to oil sealing detection device technical field, tests and fills more particularly, to a kind of valve oil seal pressure-off power
Put.
Background technology
At present, in the practical application of engine valve oil seal, on the one hand because catheter outer diameter and valve oil seal static state are close
Envelope portion compression ratio is excessive, causes pressing-in force excessive, and valve oil seal static sealing portion rubber ruptures, and chews, and presses not in place, becomes
Shape, so as to cause valve oil seal seal failure；On the other hand due to catheter outer diameter and valve oil seal static sealing portion compression ratio mistake
It is small, cause abjection power too small, when inserting valve stem, valve oil seal is deviate from from conduit, without the valve oil of flange plate structure
Envelope can also deviate from conduit when valve stem is moved；And existing evaluation method is by simulating actual installation situation, because not having
Suitable frock measurement pressing-in force abjection power, and the size of feel its strength, are entered with batch using preferable valve oil seal is fed back
Row compares.The method error is larger, it is impossible to obtain specific data, and experience hardly possible accumulation can not provide foundation to subsequent design.
The content of the invention
The purpose of this utility model is to improve the deficiency of prior art and whether provide a kind of checking valve oil seal because of pressure
Enter that power is excessive or abjection power is too small causes deformation, the rupture of not in place and rubber, valve oil seal simple in construction, easy to install
Pressure-off force test device.
The purpose of this utility model is achieved in that a kind of valve oil seal pressure-off force test device, is characterized in the dress
Put including frock on the lower frock being made up of conduit, fixed block, base, the pressing-in force being made up of pressed-in block, mandrel and connector
And frock in the abjection power being made up of abjection block, connector；
Described lower frock is that fixed block is fixedly mounted on base, and conduit is arranged in fixed block center and passes through bottom
Bolt is fixed, and the outer wall of conduit is provided with mark line；
Frock is that center is provided with installation in the cavity provided with installation oil sealing to be measured in pressed-in block, cavity on described pressing-in force
The mandrel of oil sealing to be measured, pressed-in block is movably arranged on the bottom of connector；
Frock is to deviate from the bottom that block is movably arranged on connector in described abjection power, and described abjection block is abjection block
Provided with inside interior crotch at the lower ending opening of internal cavity.
Compared with the prior art the utility model has following distinguishing feature and good effect：The utility model has used existing
The conduit used in the operating mode of field, simulates actual installation state, and the acquisition of pressing-in force and abjection power is more accurate.Deviate from crotch in block
Design, measured reverse strength, broken routine Fixture Design thinking, dexterously measured the abjection of valve oil seal
Power；Using the utility model, abundant valve oil seal pressing-in force abjection force data is obtained, design verification and design considerations are carried
Strong support is supplied so that valve oil seal design more rationally, improves the service life of valve oil seal.
Brief description of the drawings
The utility model is described in further detail with implementation below in conjunction with the accompanying drawings.
Fig. 1 is a kind of structural representation of frock under the utility model.
Fig. 2 is a kind of structural representation of frock on the utility model pressing-in force.
Fig. 3 is a kind of structural representation that the utility model deviates from frock in power.
In figure, 1, pressed-in block, 2, mandrel, 3, abjection block, 4, conduit, 5, fixed block, 6, lower frock, 7, work on pressing-in force
Dress, 8, frock in abjection power, 9, mark line, 10, base, 11, connector, 12, interior crotch.
Embodiment
A kind of valve oil seal pressure-off force test device, reference picture 1, Fig. 2, Fig. 3, the device include by conduit 4, fixed block 5,
Frock 7 and by abjection block in lower frock 6 that base 10 is constituted, the pressing-in force being made up of pressed-in block 1, mandrel 2 and connector 11
3rd, frock 8 in the abjection power that connector 11 is constituted, described lower frock 6 is that fixed block 5 is fixedly mounted on base 10, conduit 4
Fixed in the center of fixed block 5 and by bottom bolts, the outer wall of conduit 4 is provided with mark line 9；Work on described pressing-in force
It is mandrel 2 of the center provided with installation oil sealing to be measured, pressed-in block in the cavity provided with installation oil sealing to be measured in pressed-in block 1, cavity to fill 7
1 is movably arranged on the bottom of connector 11；The abjection of frock 8 block 3 is movably arranged under connector 11 in described abjection power
Portion, described abjection block 3 is deviate from the lower ending opening of block internal cavity provided with inside interior crotch 12.
Conduit 4, fixed block 5, base 10 are fixed together by soket head cap screw spring washer constitutes lower frock 6, first
Lower frock 6 is installed under testing equipment on movable block, connector 11 is fixed on testing equipment on fixed block, pressed-in block 1
And mandrel 2 is connected with connector 11, frock 7 on composition pressing-in force, it would be desirable to which the valve oil seal of measurement loads frock 7 on pressing-in force
In, contacted by mandrel 2 with oil seal lip, realize radial positioning and fixation, valve oil seal is not fallen out, valve oil seal flange upper end
Face is contacted with the lower surface of pressed-in block 1, realizes that end face is positioned, and is started movable block under experiment, equipment and is driven lower frock 6 to move up, mandrel 1
Conduit 4 is inserted, lower movable block upper-lower position sensor is set, test parameters is set, the maximum force mode of selection test moves on to speed
150mm/min, conduit 4 is pressed into by valve oil seal, when valve oil seal lower surface is alignd with the mark line 9 on conduit 4, i.e., upper position
The position of sensor, pressing-in force off-test, lower movable block return, valve oil seal is stayed due to the effect of 4 compression ratios of conduit
Onto conduit 4, pressing-in force is recorded；It is connected using abjection block 3 with connector 11, frock 8 in composition abjection power, mobile device is moved down
Motion block is moved up, and the lower surface of valve oil seal is moved to the top of the upper surface of crotch 12 in abjection block 3 bottom, setting examination on conduit 4
Proved recipe to, be reverse, lower frock 6 is moved down, due to the effect of interior crotch 12, valve oil seal departs from conduit 4, off-test,
Record abjection power.
The frock has used the conduit used in field working conditions, simulates actual installation state, and pressing-in force and abjection power are obtained
It is more accurate to obtain.Deviate from the design of crotch in block 3, measured reverse strength, break the Fixture Design thinking of routine, it is ingenious
The abjection power of valve oil seal is measured in ground.
