According to the testing result of the first detection piece 410, drive rotor 200 that rocking arm 300 is driven to rotate by drive component 500, so that
Rocking arm 300 is automatic, accurately rotates to preset measurement direction, realizes and surveys smoothly to advance along preset measuring route
Amount.
Specifically in the present embodiment, measurer for thickness 10 further includes the rotation being installed on rotor 200 and pre-tightens component
700.Rotation pre-tightens component 700 and includes elastic preload piece (not shown) and the second shaft 710.Second shaft 710 connects with rocking arm 300
It connects, to be rotated with axis relative rotor 200 of the rocking arm 300 simultaneously around the second shaft 710.Elastic preload piece and the second shaft 710
Connection, can pre-tighten the second shaft 710 in initial position, and rotates in the second shaft 710 and deviates initial position
When the second shaft 710 is forced to reset.
It should be pointed out that in the present embodiment, the initial position of the second shaft 710 refers to that rocking arm 300 is in deviate and erects
Nogata is to the location of second shaft during certain angle 710, at this point, rocking arm 300 is also at the initial position of itself.In addition,
Elastic preload piece is specially torsional spring.
By setting elastic preload piece, rocking arm 300 is pre-tightened in the position for deviateing numerical value direction certain angle, so as to make
Rocking arm 300 is obliquely abutted against with workbench 30, and during abutting, and 300 and second shaft 710 of rocking arm can overcome bullet
The elastic reset active force of property preload piece and relative rotor 200 rotates, occur to connect firmly with workbench 30 to avoid rocking arm 300
It touches, effectively reduces the damage of measurer for thickness 10 and workbench 30.Meanwhile board under test part 20 is measured in rocking arm 300
During, elastic preload piece the elastic reset active force of the second shaft 710 can also be forced rocking arm 300 always with board under test
The surface of part 20 keeps contact, plate 20 to be measured is detached to avoid rocking arm 300, so as to improve measurement accuracy.

The rotation axis of rotor 200 is set in parallel.It, can be by contact of 300 end of rocking arm with measurement surface by setting idler wheel 900
Become being in rolling contact from sliding contact, so as to reduce the resistance that measurer for thickness 10 is advanced along preset path, improve and measure essence
Degree.
In addition, along the direction far from rotor 200, the cross-sectional area of rocking arm 300 is gradually reduced, and can reduce 300 end of rocking arm
The weight at end reduces the frictional force of 300 end of rocking arm and contact surface so that the steering of rocking arm 300 is more flexible.
The measurement process of plate 20 is specifically described in above-mentioned measurer for thickness 10 with reference to Fig. 3 to Fig. 5.It needs
It is noted that before following measurement process, plate 20 to be measured is positioned on horizontal table 30, and pass through driving
Component 500 rotates rotor 200 and rocking arm 300 to the direction consistent with default measuring route.
As shown in figure 3, measurer for thickness 10 is located at the top of workbench 30, and not with workbench 30 or plate to be measured
20 contacts.Under the action of rotation pre-tightens component 700, rocking arm 300 is in initial position and remains stationary as, in initial position,
The angle that rocking arm 300 is formed with vertical direction is A, and the second detection piece 420 can detect and export rocking arm 300 and vertical direction
Included angle A.
When starting to measure 20 thickness of plate, 10 vertical motion of measurer for thickness is made to move closer to workbench
30。
As shown in figure 4, when idler wheel 900 is contacted with 30 surface of workbench, due to the barrier effect on 30 surface of workbench, rolling
Wheel 900 with rocking arm 300 around around the second shaft 710 axis rotation, the second detection piece 420 can detect and export rocking arm 300 with
The included angle B of vertical direction.Under the elastic reset active force applied in elastic preload piece to the second shaft 710, the second shaft 710 and
Rocking arm 300 has the tendency that returning to initial position, and idler wheel 900 is caused to be pressed on 30 surface of workbench always.In thickness measure
It is whole to be moved along the path direction to be measured of plate 20 to be measured in the case that 10 vertical direction of device remains stationary as.
As shown in figure 5, when the idler wheel 900 on rocking arm 300 is pressed onto on plate 20 to be measured, in 20 barrier effect of plate to be measured
Under, idler wheel 900 forces 300 and second shaft 710 of rocking arm to be rotated around the axis of the second shaft 710, finally so that idler wheel 900 is pressed in
The upper surface of plate 20 to be measured, at this point, the second detection piece 420 detects and exports the angle C of rocking arm 300 and vertical direction.
Since the rotation axis and idler wheel 900 of 300 relative rotor 200 of rocking arm are with respect between the rotation axis of rocking arm 300
Distance is known and fixed value, and when measuring in measurement process without plate 20 to be measured, the angle of rocking arm 300 and vertical direction
For B, when having board under test part 20, rocking arm 300 and the angle of vertical direction are C.Assuming that 20 thickness of plate to be measured is T, 300 phase of rocking arm
The distance between rotation axis of the opposite rocking arm 300 of rotation axis and idler wheel 900 to rotor 200 is L.It therefore can by Pythagorean theorem
The thickness for obtaining plate 20 to be measured is:T=L × COS (180 ° of-B)-L × COS (180 ° of-C)
During in measurer for thickness 10, preset measuring route is advanced along plate 20 to be measured, the second measuring piece energy
The situation of change of enough detection rocking arm 300 and vertical direction angle C in real time, and default measuring route is calculated using above-mentioned formula
The thickness value information of upper any position plate 20.
