Embodiment:
As shown in Figure 3, the dynamic thicknessmeter of lever comprises base plate 16, bearing 9, fulcrum 8, digital display dial gauge support, lever 1, digital display dial gauge 2, zero-point positioning device, bearing 19 and 20, counterbalance weight 3,4.
Wherein, bearing 9 is fixed on the base plate 16, and the top of bearing 9 is the fulcrum 8 of lever, and bearing 9 links to each other with the support of digital display dial gauge 2 simultaneously, and the digital display dial gauge support comprises member 10,17,15, is used for carrying and supports digital display dial gauge 2.In the actual measurement process, the digital display dial gauge that preferred mass is reliable, highly sensitive is to guarantee or to improve the accuracy of measurement.
Lever 1 framework is on fulcrum 8, and it should have enough intensity and rigidity, guaranteeing stable in measuring process, as, the lever material can be selected stainless steel material for use.It is generally bascule, but also can use multiplying lever according to different needs.The length of lever does not have absolute limitations, and those skilled in the art can select suitable length according to actual needs.
One end termination of lever 1 is equipped with head bearing 19, and head bearing 19 is fixed on the lever, and lower bearing 20 is fixed on the top of zero-point positioning device, and head bearing 19 is centered close on the perpendicular line perpendicular to base plate 16 with lower bearing 20.The zero-point positioning device is made of member 11,12,13,14 and is fixed on the base 16.The other end of lever 1 contacts with the table bar measuring head of digital display dial gauge 2.In the time of between measured object is by head bearing 19 and lower bearing 20, because lower bearing 20 is fixed on the zero-point positioning device, the thickness of measured object will make head bearing 19 be elevated and produce displacement, its displacement will inevitably cause the rotation of lever 1, make the other end of lever 1 produce displacement downwards, thereby the height change of this end is delivered to the digital display dial gauge 2 of the other end, is reacted on the reading of digital display dial gauge.
Metal (upper 19,20 is preferably precise rolling bearing, and head bearing 19 small height change can both be by lever transmission to digital display dial gauge like this.And in the kinetic measurement process, measured object moves through between bearing 19 and 20 continuously with certain speed, and it is very little that friction force becomes, and so just is difficult for making measured object to produce the unnecessary vestige that weighs wounded.Particularly in measuring coating process during the pole piece of fast moving, it is particularly important that the use of precision bearing seems.
With measured object mutually on the lever arm of the same side, also be provided with a counterbalance weight 4.The position of counterbalance weight 4 on lever is to regulate according to the hardness difference of measured object, is screwed on lever arm.The size of counterbalance weight 4 can design according to the size and the actual needs of lever, also can select by concrete operational testing.
Annotate: thicknessmeter should be moved apart measured object before using the dynamic thicknessmeter of lever, the clock gauge reading is made zero.
The lever that uses in following examples is long stainless steel round bar as 260mm, diameter 14mm, and counterbalance weight 4 is a rectangular parallelepiped, is of a size of 60*40*25mm; Counterbalance weight 3 is a right cylinder, is of a size of 30*40mm.
