Description
Technical field
The utility model is related to measuring appliance technical field, and in particular to a kind of cylinder crankshaft hole pneumatic amount of multi-section
Instrument.
Background technology
After cylinder block completion of processing, it is necessary to measure packet to crankshaft hole in addition to wildcard type.To make measured value try one's best
Close to actual value, client typically may require that two sections of every grade of survey, and 2 directions are surveyed in each section, then 4 numbers of measurement
The average value of value is used as final grouped data.
Conventional metering system is the general aerodynamic amount instrument using the double stomatas in single section, every time one on one section of measurement
Individual direction, measures 4 times, obtains 4 measured values, then the average value of 4 measured values of manual record and calculating.In this process
In, sectional position, the angle position of measurement are because without positioning inhibiting device, can only lean on the experience of survey crew to estimate big position
Put.Meanwhile, air-gauge measured value is usually to retain after decimal point 4, is manually entered and also easily error in calculating process.
In summary factor, often results in the measurement result of our reality and letting down for client.There is such case
Afterwards, client is strongly required to do over again to remeasure packet, and batch is returned goods when serious, and CSAT is poor, complains very serious.
Utility model content

Positioning sleeve is determined.Meanwhile, on handle mark angle instruction line, operating personnel by instruction line vertically upward, you can ensure nozzle
The angle in direction；Different watt shelves, can be accurately positioned by changing positioning sleeve, solve the problems, such as measurement and positioning.
(2) measurement result is handled by inductance amesdial, calculated, and directly exports average, without being manually entered and calculating,
Solve the problems, such as the error for being manually entered and calculating.
(3) measurement, packet is become simple and convenient, survey crew's professional standards required to reduce, cost of labor is reduced,
Measurement efficiency and accuracy rate are improved, client's complaint is eliminated.
Brief description of the drawings
The following drawings is only intended to, in doing the utility model schematic illustration and explanation, not limit model of the present utility model
Enclose.Wherein：
Fig. 1 is the structural representation of the utility model embodiment.
In figure：1- measuring staffs；The 11- bodies of rod；12- composite probes；13- surveys stomata；2- handles；3- positioning sleeves.
Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only by saying
Bright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be with
Recognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility model
Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim
Scope.
As shown in figure 1, cylinder crankshaft hole multi-section air-gauge, including measuring staff 1 and handle 2；Wherein described measuring staff 1 is wrapped
The body of rod 11 is included, the outer circumferential side of the body of rod 11 is set with positioning sleeve 3, and the end of the body of rod 11 is provided with composite probe 12；This
In embodiment, the composite probe 12 is axially disposed two measurement sections, each distinguishes radially on the measurement section
Two groups of survey stomatas 13 are offered, stomata position is surveyed and measurement position is consistent；The handle 2 is connected with the measuring staff 1, described
Angled instruction line is marked on handle 2.Using bent axle hole end surface as axially position during measurement, gauge head nozzle location is true by positioning sleeve 3
Fixed, angle instruction line is vertically upward during operation, you can ensure the angle of nozzle direction, so as to solve the problems, such as measurement and positioning.
In order to avoid artificial input data and calculation error problem, the composite probe 12 is preferably connected pneumatic-to-current converter,
The pneumatic-to-current converter is connected with inductance amesdial (not shown), and measurement signal is delivered to mini-inductance measurement after being changed through signal
Instrument carries out computing and processing, and measurement result is handled by inductance amesdial, calculated, and average is directly exported, without being manually entered
And calculating.Wherein, inductance amesdial is common instrument known in the art, and its concrete structure and operation principle are no longer carried out in detail
State.
The positioning sleeve 3 is preferably removably set on the body of rod 11, so different watt shelves, can be fixed by changing
Position covers 3 to be accurately positioned, so as to improve the versatility of air-gauge.
In addition, the composite probe position easy to wear is preferably with bearing steel or grinding tool steel；Flexible member uses high-quality bullet
Spring steel, other structures part can use Fine Steel Casting iron or aluminium alloy.
Certainly, inductance amesdial can show each road sensor parameters simultaneously, can store measurement data, be convenient for data point
Analysis, can judge whether workpiece is qualified, and result of determination (OK/NG) intuitively can be shown on screen by the margin of tolerance of setting, or
Pass through external acousto-optic warning device teaching process person.Touch screen human-computer interface can be used, working interface is provided with, adjusts manually
Whole interface, measure interface, correction interface and data query interface etc..
Specific measurement process is as follows：
First, calibrate：Measuring system is calibrated with standard ring.
2nd, detect：After survey crew's hand-held handle, the suitable location that is loaded set, measured hole is inserted, measurement button is pressed, electricity
Case, which is received, starts measurement after signal.
3rd, positioning sleeve is changed, next hole is measured.
4th, data acquisition and processing (DAP)：Measurement signal is delivered to CPU and carries out computing and processing after being changed through A/D, automatic to calculate
Obtain the size of user's requirement.
Using this utility model air-gauge, the time of measuring at each position is compressed to 5-8 seconds (without used in transfer cylinder body
Time), Measurement Resolution can reach 0.1um, 10 same workpiece of duplicate measurements (or standard component), and measurement error is not more than
(circularity of workpiece shape position error, such as detection site, ovality and other surface defects are to measurement for the 10% of measured size tolerance
As a result influence is not belonging to the measurement error of this equipment).Measurement and calculation error are solved, measurement, packet is become simple side
