Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not limited by detailed description of the invention.
Explicitly indicating that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or it becomes
Change and such as " comprising " or " including " etc. will be understood to comprise stated element or ingredient, and do not get rid of other yuan
Part or other ingredient.
As it is shown in figure 1, the sensor mounting hole detecting tool of the detonation pressure sleeve according to this utility model detailed description of the invention
Can install " detonation pressure sleeve " front, underproof " detonation pressure sleeve " reject out, it is ensured that " the detonation pressure sleeve " installed all
It is certified products, reduces the waste of human and material resources, ensure being smoothed out of pilot development.The sensor mounting hole of this detonation pressure sleeve
The concrete structure of detecting tool includes: detection head pull bar 1 and installing hole detection 2, and wherein, installing hole detection 2 is fixed on inspection
The lower end of gauge head pull bar 1, puts in the detonation pressure sleeve 3 needing to check by detection head pull bar 1 by installing hole detection 2, checks
Whether installing hole detection head can be completely in the ladder installing hole of the sensor of detonation pressure sleeve, and eligible state is installing hole detection
Head completely in ladder installing hole, and can have the slight sense that contacts with installing hole, but not clamping stagnation.The sensing of this detonation pressure sleeve
Device installing hole detecting tool can judge that the size of the sensor ladder installing hole of detonation pressure sleeve and axiality are fast and accurately
No meet use requirement, it is to avoid unnecessary human and material resources and waste of time, improve the progress of pilot development.Avoid
Underproof detonation pressure sleeve enters and installs and uses link, the detonation pressure sensor degradation therefore caused.
Specifically, as in figure 2 it is shown, detonation pressure sleeve 3 is cylindric, its underpart inner chamber have the macropore 31 by top and under
The ladder installing hole of aperture 32 composition in portion, this ladder installing hole is used for installing detonation pressure sensor.Macropore 31 and aperture 32 belong to
Deep hole, small structure, it is difficult to processing, and part machine after again cannot with conventional measurer to the size of ladder endoporus and
Axiality checks.So the quality of detonation pressure sleeve cannot ensure, cause use during " detonation pressure sensor " sometimes
Cannot install and put in place, therefore cause damaging sensor by pressure when compressing " detonation pressure sensor " meeting.
As it is shown on figure 3, detection head pull bar 1 be multidiameter structure, including: the superposed first big axle 11 be positioned at this
First little axle 12 of one big axle 11 bottom, the first big axle 11 is six prism structures, and its top offers the first axial thread and connects
Hole, the lower end of the first little axle 12 has external screw thread, for being connected fixing with installing hole detection 2.
As shown in Figure 4, installing hole detection 2 be multidiameter structure, including: superposed second largest axle 21 be positioned at this
Second little axle 22 of second largest axle 21 bottom, it is adaptive that the top of second largest axle 11 offers the external screw thread with the first little axle 12 lower end
The the second axial thread connecting hole being spirally connected.Second largest axle 21 is adaptive with the macropore 31 of detonation pressure sleeve 3 to be inserted；Second little axle 22 is with quick-fried
The aperture 32 of gland cylinder 3 is adaptive to be inserted, and the most second largest axle 21 and the size of the second little axle 22 and axiality meet qualified detonation pressure set
The use requirement of the sensor ladder installing hole of cylinder, it is possible to judge the sensor ladder installing hole of detonation pressure sleeve fast and accurately
Size and axiality the most qualified.
It is embodied as step:
1. the external screw thread of detection head pull bar is screwed in the screw of installing hole detection head.
2. with detection head pull bar connect installing hole detection head put in need check detonation pressure sleeve in, check install
Whether hole detection head can be completely in the ladder installing hole of the sensor of detonation pressure sleeve.
3. as can not be completely into, then it represents that size or the axiality of the installing hole of sensor are defective.
4. if completely into but too tight, represent that the size of the installing hole of sensor is less than normal or axiality is defective.
5. if completely into but the most loose, i.e. installing hole detection head can swing in ladder installing hole, expression sensor
The size of ladder installing hole is bigger than normal.
6. the detonation pressure sleeve eligible state checked is: installing hole detection head can completely in ladder installing hole, and with peace
There is a slight contact sense in dress hole, but not clamping stagnation.
To sum up, the sensor mounting hole detecting tool of this detonation pressure sleeve can judge the biography of detonation pressure sleeve fast and accurately
Whether size and the axiality of sensor ladder installing hole meet use requirement, it is to avoid unnecessary human and material resources and time
Waste, improves the progress of pilot development.Avoiding the entrance of underproof detonation pressure sleeve and install and use link, therefore cause is quick-fried
Pressure sensor damages.
