Bottom fix a steel ball 46, the minimum point of steel ball for contacting cooperation with metope.Steel ball is hollow-core construction, and quality is the least,
The setting of steel ball should ensure that when spring is in vertical state, and the pulling force of spring is ignored by steel ball, and the deformation of spring is trickle,
Steel ball should have certain hardness simultaneously.Force transducer is connected with single-chip microcomputer signal by wire, single-chip microcomputer and monitor signal
Connect.
As shown in Fig. 2, Fig. 5, Fig. 6, being rotatablely equipped with the first supporting leg 5 in each breach, the first supporting leg is overall Cheng Yuan
The hollow metal bar of shape, the top of the first supporting leg is installation portion 51, and installation portion is the square metal being welded and fixed with the first supporting leg
Block, the first supporting leg is rotationally connected with pedestal by installation portion, and therefore the first supporting leg can rotate disorder of internal organs lower swing in the heart, for realizing
Being relatively fixed of one supporting leg, is provided with the otic placode 12 of a U-shaped, sets on otic placode in the bottom of the pedestal being positioned at each gap position
There are some first screwed holes 121, as shown in Figure 4, by through the first screwed hole and the 4th jackscrew 84 of the first supporting leg installation portion
Realize being relatively fixed of the first supporting leg and pedestal.Being provided with the second supporting leg 6 in the inner chamber of the first supporting leg, the second supporting leg is circular
Metallic rod, the second supporting leg slides along the axis direction of the first supporting leg.The most solid for realize between the second supporting leg and the first supporting leg
Fixed, between each first supporting leg and the second corresponding supporting leg, it is provided with one first jackscrew 81.Second supporting leg and the first supporting leg can be stretched
The design of contracting formula, can be easy to fold and improve the adaptability of whole device.For improving the retractility of whole device further and fitting
Ying Xing, the second supporting leg is hollow structure, is equipped with one the 3rd supporting leg 7 in the inner chamber of each second supporting leg, and the 3rd supporting leg is circle
The metallic rod of shape, for realizing being relatively fixed between the 3rd supporting leg and the second supporting leg, at each second supporting leg and the corresponding the 3rd
Being provided with the second jackscrew 82 between supporting leg, for avoiding the second jackscrew to impact the flexible of the second supporting leg, the second jackscrew is arranged on
On the outer wall of the second supporting leg foot.The bottom of the 3rd supporting leg is used for contacting cooperation with metope, as it is shown in figure 9, for avoiding the 3rd
Metope is damaged by the bottom of supporting leg, and the bottom of the 3rd supporting leg is set to hemispherical 71.
For obvious irregular metope, can be observed by naked eyes；Wall surface levelling can not be directly found out for naked eyes
In the case of degree, the range size sampled as required, the 3rd supporting leg is extracted out from the second supporting leg, by the second supporting leg from first
Supporting leg is extracted out, and by the first jackscrew, the first supporting leg and the second supporting leg is locked, by the second jackscrew by the second supporting leg and the
Three supporting leg lockings.First, second, and third supporting leg often cooperated constitutes supporting leg, during work, should ensure that three supporting legs
Length identical, now three supporting legs surround a positive triangular pyramid, the bottom of three the 3rd supporting legs determine one put down
Face, is designated as datum level.Second rotating cylinder is extracted out from the first rotating cylinder, unclamp bolt rotate movable block make spring free end towards
Metope 10 to be measured, and by bolt, movable block is fixed.As required, activity cross bar is extracted out from fixed transverse rod, and leads to
Cross the 3rd jackscrew locking.Now, the first rotating cylinder, the second rotating cylinder, montant, spring are perpendicular to datum level.Regulate the second rotating cylinder
Position in one rotating cylinder, first makes steel ball and a little just contacting on metope to be measured, the most micro-to metope place to be measured
Side move steel ball, and lock the 3rd jackscrew.Now steel ball may be on datum level with the contact point of metope to be measured, it is possible to
Can not be on datum level, certain spring force experienced by force transducer, is designated as X.As shown in Figure 10, Figure 11, by whole detection
Device is placed on metope 10 to be measured, it is ensured that the end of three supporting legs contacts with metope to be measured.Then swing handle so that
Steel ball rotates around the axis of the first rotating cylinder.Due to metope to be measured on microcosmic uneven, therefore, steel ball is with fixed transverse rod
During rotating with movable cross bar, steel ball separates with metope to be measured sometimes, and now, the spring force of force transducer perception is
Zero.Sometimes steel ball and metope to be measured are pressed further by effect so that spring the most by compression, now force transducer perception
Spring force is Y, and the value that Y is more than X.Spring transfers force on force transducer, and then the size of force transducer perception will
Data are delivered to record on single-chip microcomputer, and show over the display, and after steel ball turns over 360 degree, change activity cross bar is fixing
Again lock behind position in cross bar, and swing handle makes steel ball turn over 360 degree again, again records one group of data.Power passes
When the data of sensor perception are the biggest, show that metope highlights the most, when the data of record are more disperseed compared with X value, such as figure
Shown in 12, now show that degree of plainness for wall surface is poor.When the data value Relatively centralized recorded, as shown in figure 13, show metope
Flatness is preferable, and degree of plainness for wall surface meets the requirements.
