As preferably, described measuring head is semisphere, and described integrated pipe front end forms an opening, and the arcuate surface of measuring head is positioned at outside opening.This setting can facilitate the connection of integrated pipe and measuring head, can realize again the movement of measuring head.
In sum, the present invention has the following advantages: described micro-displacement digital measuring device structure is simple, and easy to operate, cost is low, and measuring accuracy is high, and usable range is wide.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In order to make those skilled in the art person better understand the present invention program, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention.
As shown in Figure 1, a kind of micro-displacement digital measuring device, comprise sensing part 1 and signal transacting display section 2, sensing part 1 is connected with signal transacting display section 2.
Concrete, described sensing part 1 comprises a fixed body 11, moving body 12 and piezoelectric ceramics 13, and described fixed body 11, moving body 12 and piezoelectric ceramics 13 are all packaged in an integrated pipe 3; The front end of described piezoelectric ceramics 13 is adjacent to moving body 12 rear end, and the rear end of piezoelectric ceramics 13 is adjacent to the front end of fixed body 11; A measuring head 14 is fixed in the front end of moving body 12; Described fixed body 11 is fixed on the rear end of integrated pipe 3, moving body 12 and measuring head 14 are located at the front end of integrated pipe, and moving body 12 and measuring head 14 can move forward and backward in integrated pipe 3, described fixed body 11 and moving body 12 are the right cylinder fitted with integrated pipe 3 inwall, and described piezoelectric ceramics 13 is for being located at the ceramic bar of the center position of fixed body 11 and moving body 12.Measuring head 14 is in semisphere, integrated pipe 3 front end forms an opening, the arcuate surface of measuring head 14 is positioned at outside opening, and the smooth surface of measuring head 14 is bonding with moving body 12 front-end surface, and be positioned at integrated pipe 3, integrated pipe 3 front edge is provided with to edge in projecting inward, and the bottom margin of measuring head 14 arcuate surface near even surface place can be stuck in integrated pipe by interior edge, and interior edge can prevent measuring head 14 from departing from integrated pipe 3.Described signal transacting display section 2 comprises signal processor 21 and display 22, and signal processor 21 is connected with piezoelectric ceramics 13 by the first connecting line 4, and signal processor 21 is connected with display 22 by the second connecting line 5.
Use procedure: measuring head contacts with surface of the work, when measuring head 14 promotes by parts micro-displacement, moving body 12 also moves thereupon, piezoelectric ceramics 13 is pressed on fixed body, piezoelectric ceramics 13 is stressed and produce electric signal, the size of this electric signal and piezoelectric ceramics 13 and the pressure correlation suffered by measuring head 14.Described electric signal outputs on signal processor 21 by the first connecting line 4, after the treated device process of signal, is transferred on display 22 shows by the second connecting line 5.When parts return a micro-displacement, then measuring head 14 also moves same displacement to integrated pipe 3 front, moving body 12 is driven also to move same distance to integrated pipe 3 front, this makes piezoelectric ceramics 13 be pressed in the corresponding reduction of power on fixed body 11, by the signal also corresponding reduction that the first connecting line 4 exports, the numeral also corresponding reduction that treated device process also shows on display 22.
