Specific embodiment
Detailed description of the present invention embodiment with reference to the accompanying drawings.
In order to provide a kind of monitoring method of engine quality mass center that can meet Multiple Type plurality of specifications simultaneously, this
Invention has developed a kind of integration height convenient for the detecting tool of operation comprising:
(1) carrier unit
Carrier unit mainly completes the supporting role to measurement product, have manual adjustment in a certain range it is axial and
The function of radial spacing can be no directly as in two back-up roller wheels of carrier unit if engine shape is regular cylindrical shape
It can be then supported in two back-up roller wheels of bracket according to engine sShape features with engine measuring idler wheel is made.
It is specific as shown in Figure 1, 2, setting is there are two sliding support 2 on the sliding rail of support platform 1, on each sliding support 2
Adjustable rolling frame 3 there are two one group is set, back-up roller wheel is installed in adjustable rolling frame 3, two sliding supports 2 can be along sliding rail
Position is adjusted, can be provided on sliding support 2 according to the spacing between two sliding supports 2 of length adjustment of engine
Several are adjustable 3 link position of rolling frame can adjust between two adjustable rolling frames 3 radially according to the diameter of engine
Distance.
Carrier unit measures installation when installing, and to guarantee that height is consistent before and after each back-up roller wheel center, and requires circle
Machining accuracy control is spent within ± 0.10mm.Back-up roller wheel spacing is manually adjustable, guarantees engine within the specified scope
Product can stablize support on bracket.
To measure product Y, Z-direction mass center, bracket guarantees be rotated by 90 ° by the achievable rotation of support wheel, measuring system
The measurement of achievable Y, Z-direction mass center within the scope of ± 20 °, simultaneous computer software systems should have rotation angle to show.
Carrier unit is mainly used to realize the support and rotation of measurement product, full by the adjustment of axially and radially distance
The support demand of different model engine within the scope of sufficient a certain range outer dimension, in which:
1) sliding support: cooperate with the sliding rail on weighing platform, Support Position of two sets of supports on platform may be implemented
Freely adjust, to adapt to the Support Position of different product.
2) adjustable rolling frame: for realizing product rotating freely around axis.Every set is adjustable to be set between rolling frame and sliding support
Different product diameters is adapted in respect of several link positions, the symmetrical galassing of rolling frame that two sets on same sliding support are adjustable
The plane of symmetry of platform is symmetrical, to guarantee the symmetry axis of product on the plane of symmetry of test desk.
3) support platform: being pin hole cooperation with the elevating lever in elevating mechanism, in weighing shape for supporting engine product
Under state, elevator bar is fallen, and support platform is contacted with weighing sensor, realizes the weighing of engine, under non-weighing state, is risen
Descending mechanism rises, and support platform and weighing sensor are detached from, and weighing sensor is avoided to be in the state that works long hours and lead to the longevity
Life shortens.
Every set bracket need to provide master body one, and for the calibration of system accuracy, master body weight should be bracket survey
Measure the 50% of range.Geometric dimension, quality and its axial and two radial directions centroid position of master body pass through qualified
Foundation of the data as checking system overall precision is examined and determine in metrological service's calibrating.
(2) pedestal
As shown in figure 3, pedestal includes base platform 4, stabilizer blade 5 and coaming plate 6, base platform 5 is for installing weighing measurement machine
Structure, elevating mechanism, horizontal adjusting mechanism etc. realize the installation, leveling and fixation of weighing sensor；Stabilizer blade 6 has support and adjusts
The function of base plate level is saved, after regulating stabilizer blade, then adjusting auxiliary support mechanism makes it play the role of systems stabilisation, in total
There are six sets of stabilizer blades and whole auxiliary support mechanism；Coaming plate 7 is the shell of test desk.
(3) weighing unit
Weighing unit includes sensor and regulating device, the parts such as analog-to-digital conversion and transmitter.
Since weighing sensor precision is mostly related with its range, therefore, in order to ensure that the measurement accuracy of engine quality mass center,
During testing different quality engine, the weighing sensor of different range abilities need to be used.Sensor is at isoceles triangle
Shape distribution.Keep its center line substantially parallel with the measurement axis of product (its angle controls within 0.1 degree) by measuring installation,
The height of sensor is identical.Physical quantity is converted into analog voltage signal by sensor, passes through analog-to-digital conversion and transmitter simulation letter
Number it is converted into digital quantity, then computer is transmitted to by serial line interface.Computer is whole according to each sensor magnitude and power device
Body position calculates quality center of mass value.
Specifically as shown in figure 3, fixed there are three column 7 on base platform 4, three columns 7 are fixed in isosceles triangle
On base platform 4, there is a weight weighing sensor on the top of three columns 7 respectively, for starting to big heavier of specification
Machine is weighed.Three pillars 9 are in the configuration of falling isosceles triangle relative to three columns 7 that triangle is arranged, and three pillars 9 push up
End is respectively arranged with a light weight weighing sensor, and three pillars 9 respectively come with inversion mechanism 11, can pass through inversion mechanism 11
Three pillars 9 are made to be higher or lower than three columns 7, in this way, by the difference in height between loading end, Lai Shixian lightweight weigher
The switching of the working condition of structure and heavyweight Weighing mechanism.According to engineering experience, measurement knot is can be improved in the dismounting for reducing sensor
The reliability of fruit, the present invention can realize the survey for meeting super large range in the case where not disassembling sensor by inversion mechanism
Accuracy of measurement.The executive mode of inversion mechanism uses the man-operated mechanism of Purely mechanical in the present embodiment, is equipped with transposition control stick.Mechanism
It is easy to operate, safe and reliable and without the concern for Explosion-Proof.Electronic inversion mechanism can also be used.
(4) lifting unit
Motor driven lifting unit includes elevating lever 12 and transmission mechanism 13.Transmission mechanism 13 is by stepper motor, harmonic wave tooth
The composition such as speed reducer, controller is taken turns, these components are arranged on base platform 4, and lifting speed can carry out speed tune automatically
Section, saves lifting time while guaranteeing steady, effect is to hold up weighing platform by elevating lever 12 smoothly to connect with sensor
Touching is detached from, close to contact Shi Yingyou dashpot function.Stepper motor can be accurate by the pulse that controller issues
Control the adjustable height of crane.
Specifically as shown in figure 3, lifting unit includes four elevating levers 12, which is arranged in base platform 4
Four corners, four elevating levers 12 and 1 pin hole of support platform cooperate, and when not needing weighing, will be propped up by four elevating levers 12
Frame unit is held up, and is not contacted weighing sensor, when being weighed, by configuring transmission mechanism 13 on base platform, is made to rise
Bar decline is dropped, carrier unit is landed on column 7 or the pillar 9.
The preferred embodiment of the present invention is illustrated above, but the present invention is not limited to above-described embodiments.It is right
For those skilled in the art, in the scope documented by claims, it should be apparent that it is conceivable that various modifications
Or fixed case, technology scope of the invention is also belonged to certainly.
