a kind of piston type foil gauge fast-positioning device and localization method
Technical field
The present invention relates to electric detecting technology field, be specifically related to a kind of piston type foil gauge fast-positioning device and localization method.
Background technique
Also claim resistance strain gage at strain gauge, being called for short foil gauge or resistance strain gauge, is the element being configured for monitor strain by sensitive grid etc.The change that mechanical component strains can be converted to resistance variations by it.
Before pasting foil gauge, upper cleaning solvent need be dipped in rayon balls, as the greasy dirt at acetone, anhydrous alcohol, carbon tetrachloride equal solvent scouring measured point place, without till obvious oil stain on cotton balls, and note now not touching the surface after cleaning with hand.Then thin layer glue is coated at the sticking veneer place of foil gauge, as KH501, KH502 glue, generally should be thin unsuitable thick.The rhumb line of foil gauge is aimed at the line in advance on test specimen, whether the line of the rhumb line and test specimen that now should keep a close eye on foil gauge overlaps, at this moment can at foil gauge upper cover last layer cellophane paper or Waxpaper, a hand pinches the lighting outlet of foil gauge, roll extrusion cellophane paper is surperficial gently repeatedly for the finger of another hand, glue unnecessary for the inside is extruded with bubble. make sure to keep in mind during roll extrusion foil gauge vertically to exert oneself, can not produce and slide or rotate, after glue and bubble are extruded completely, also should keep finger motionless about about one minute. one deck cellophane can certainly be covered in surface of test piece, then lastblock siliceous skin is padded, with the location for paste of fixture or the light compressive strain sheet of smooth briquetting, the object of these ways is all to ensure that foil gauge does not offset in taping process, ensure that its rhumb line overlaps completely with the line of position at test specimen test point place.
In electric detecting technology, the quality of strain gauge adhesion quality is very large to the reliability effect measured, it is a very critical link, must be noted. for improving the accuracy of electrical measurement result, we should will ensure the paste position strained and the accuracy of pasting direction in the taping process of foil gauge.
After above-mentioned work completes, the sticking Quality also tackling foil gauge checks, whether accurately such as observe strain gauge adhesion position and azimythal angle by magnifying glass, adhesive surface has bubble-free, foil gauge whether firm pasting; If with multimeter monitor strain sheet with or without open circuit, short circuit phenomenon. without exception, then whether meet the requirements with the insulation resistance between the lighting outlet of low pressure variable resistance table monitor strain sheet and metal specimen again.This resistance usually should reach more than 100M Europe and just can act on.
Summary of the invention
The object of the present invention is to provide a kind of piston type foil gauge fast-positioning device and localization method, this positioning device is by being fixed in the locating slot of positioning device by foil gauge, behind adjustment positioning device and the position of to be measured, foil gauge is promoted by promoting piston apparatus, thus foil gauge and to be measured the detected part scribbling glue are extruded, finally make foil gauge paste accurately in detected part.
The present invention adopts following technological scheme:
A kind of piston type foil gauge fast-positioning device, its positioning device 1 comprise handle 2, piston rod 3, piston 4, piston cylinder 5,
Piston pad 6, locating slot 7, piston mouth 8, lead wire outlet 9.
Locating slot 7 is built in piston pad 6, and piston pad 6 is arranged in piston mouth 8, can move along piston mouth about 8.
The inside of antiseize membrane placement positioning groove 7, size is equal with the length and width of locating slot; Piston mouth 8 and locating slot 7 are all provided with a lead wire outlet 9.
Locating slot 7 is identical with width with the length of foil gauge, and foil gauge is installed in locating slot 7, and foil gauge lead-in wire by lead wire outlet 9 out.
Detected part on to be measured 10 applies glue after rust cleaning, polishing, and the area of glue should be 4 ~ 5 times of bonding area.
Positioning device of the present invention, utilizes and promotes piston, make air extrusion foil gauge in piston, thus make strain gauge adhesion on to be measured that scribbles glue, and the stickup initial stage can be avoided owing to pointing the directly infringement of pressing to foil gauge; Positioning device of the present invention, the locating slot of its inside can fix foil gauge, just can reach pinpoint problem, solve the problem of positional accuracy difference when pasting foil gauge by the position and direction adjusting positioning device; Localization method of the present invention, low to operator's technical requirements, easily can realize the correct fast of foil gauge according to operational instruction and paste.
