Utility model content
For problems of the prior art, the utility model provides one can reduce operating mode, carries out the screw-contact device for measuring radial pressure of quantitative measurment.
The utility model is achieved through the following technical solutions:
A kind of screw-contact device for measuring radial pressure, comprises for carrying out the installed body of locating that is installed from screw-contact outer circumferential, is arranged on the slide strips of screw-contact week annular to the inside, and is arranged on the air bag inside slide strips; Installed body is provided with the displacement transducer of deformation displacement amount for measuring screw-contact and/or slide strips position, location; Air bag connects and adds pressure measuring device; Slide strips is the elasticity setting of opening; When air bag is inflated, slide strips is carried out sliding along the radial direction of screw-contact and radially to be exerted pressure to screw-contact.
Preferably, also comprise the limiting plate being fixed on the axial both sides of slide strips, and be arranged on the limited post inside air bag; Limited post is arranged in coaxial with air bag, slide strips and screw-contact.
Further, limiting plate is set on limited post, limited post is arranged set bolt fixing to limiting plate location.
Further, limiting plate is made up of circular steel plate, and limited post is made up of steel column.
Preferably, two ports of slide strips are in its natural state in overlapping setting.
Preferably, slide strips is made up of steel band.
Compared with prior art, the utility model has following useful technique effect:
The utility model applies pressure by adding pressure measuring device to air bag, and air bag can expand along screw-contact radial direction, and promotes slide strips generation radial slippage, thus radial deformation occurs promotion spring touch finger; And utilize displacement transducer directly to screw-contact or by carrying out accurate quantitative measurment to slide strips location to its radial pressure; And in this process, spring touch finger radial force situation is identical with actual condition, and reducing degree is high.The detection of high pressure switch, bus connecting piece, high current connection, isolating switch web member, pole and mechano-electronic screw-contact, type selecting and design can be applicable to; The product quality realizing manufacturer is helped to detect and design selection.
Further, by the restriction of limiting plate to slide strips both sides, limited post to the location of air bag and restriction, under the two acting in conjunction, air bag and slide strips only expand along spring touch finger radial direction or move, and can measure its radial pressure more accurately.
Further, the overlapping setting of slide strips can improve the rear each several part displacement of its expansion and stressed corresponding relation, the degree of accuracy ensureing its force and measure.

In figure: 1 is displacement transducer; 2 is installed body; 3 is limiting plate; 4 is set bolt; 5 is limited post; 6 for adding pressure measuring device; 7 is screw-contact; 8 is slide strips; 9 is air bag.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, described in be to explanation of the present utility model instead of restriction.
A kind of screw-contact device for measuring radial pressure of the utility model, as shown in Figure 1, comprises spring touch finger and clamps, measures and locate three parts.Clamping portion comprises the installed body 2 to screw-contact 7; Measure portion comprises air bag 9, for pressurization and tonometricly add pressure measuring device 6, and slide strips 8, limiting plate 3 and limited post 5; Localization part comprises displacement transducer 1.In this measurement device process, spring touch finger radial force situation does not change, identical with actual condition.Meanwhile, this device directly can obtain the relation between spring touch finger deflection and pressure, and then the product quality of Instructing manufacture producer detects and design selection.
The slide strips 8 of measure portion is the not closed steel band of one, and there is certain elasticity, when by adding pressure measuring device 6 pairs of air bags 9 and applying pressure, air bag 9 can expand along screw-contact 7 radial direction, and promote slide strips 8 radial slippage occurs, thus promote screw-contact 7 radial deformation occurs.In this process, screw-contact 7 radial force situation is identical with actual condition.
The limiting plate 3 of measure portion is the circular steel plate being fixed on slide strips both sides, and limited post 5 is the steel columns be fixed on inside air bag, and under the two acting in conjunction, air bag 9 and slide strips 8 only expand along screw-contact 7 radial direction or move.
Add pressure measuring device 6 to be communicated with and junction good seal with air bag 9.Add pressure measuring device during measurement and pressure is applied to air bag, and real-time pressure can be read adding on pressure measuring device.
The displacement transducer 1 of localization part is fixed on spring touch finger installed body 2, with the position of the deformational displacement amount and/or location slide strips 8 of measuring screw-contact 7.
The installed body 2 of clamping portion is simulated volute spring and is touched 7 finger actual condition designs, plays the effect of fixing screw-contact 7.
First screw-contact 7 loads in installed body 2 when detecting by the utility model, is made zero by the pressure and displacement transducer 1 of air bag 9; Then according to the deformational displacement value that screw-contact 7 presets, to air bag 9 persistent pressure, until stop pressurization when screw-contact 7 distortion reaches setting shift value, force value is now read.So, can obtain the force value under screw-contact 7 different deformation displacement, the relation between direct measuring spring fingertip deflection and pressure, the product quality of Instructing manufacture producer detects and design selection.
Specifically as shown in Figure 1, the utility model comprises displacement transducer 1, installed body 2, limiting plate 3, set bolt 4, and limited post 5 adds pressure measuring device 6, slide strips 8 and air bag 9.
