Abstract
The utility model provides a flat bottom hole and narrow groove depth measuring instrument, which comprises a dial gauge, a jackscrew, a measuring head, a fixing block, a standard measuring block, a connecting rod, and a measuring ruler, and is characterized in that the fixing block is designed to be inverted U-shaped; the middle of the fixing block is provided with the dial gauge; the lower side of the fixing block is provided with the standard measuring block; the lower end of the dial gauge is provided with the connecting rod; the connecting rod is connected with the dial gauge via the jackscrew; the measuring head is welded on the connecting rod; and the lower end of the measuring head is provided with the measuring ruler. The flat bottom hole and narrow groove depth measuring instrument has the advantages that the structure is simple, carrying is easy, operation is easy, measurement accuracy is high, and problems of inaccurate and inconvenient flat bottom hole and narrow groove depth measurement can be solved.
Description
Technical field
The utility model relates to Technology of Precision Measurement field, the flat-bottom hole adopting in a kind of UT (Ultrasonic Testing) process specifically or the accurate measuring appliance of the degree of depth of flute profile defect.
Background technology
In the manufacture process of ultrasonic flaw detection briquette, the hole depth of some product and groove depth require very strict, and because aperture is less, groove width is narrower, adopts general measuring equipment and measuring method cannot complete measurement task at all.Slightly larger hole was all to adopt the Sounding Rod of vernier caliper to enter measurement in hole in the past, but this kind of method measuring accuracy is not high, usually do not reach measurement requirement, the depth gauge that the flat-bottom hole of path and narrow groove are often manufactured by tool department is measured indirectly, manufacture the cycle that this depth gauge need to be longer, and improved again cost of goods manifactured, product can not be delivered to customer in time; As use three-coordinates measuring machine to measure, not only cost is too high, and measuring process is slow, has a strong impact on product machine process.
Development along with Dynamic Non-Destruction Measurement, client is also more and more higher to the precision of ultrasonic flaw detection briquette, for can access reliably, testing result accurately, this just need to be equipped with accurate survey instrument, the survey instrument measuring accuracy of prior art is low, detection speed slow, it is inconvenient to use.
Summary of the invention
For solving an above-mentioned difficult problem, the utility model provides a kind of measuring accuracy high, detection speed is fast, flat-bottom hole easy to use and narrow groove depth measuring appliance, described flat-bottom hole and narrow groove depth measuring appliance are by dial gauge, jackscrew, measuring head, fixed block, standard gauge block, connecting link, dip stick forms, it is characterized in that fixed block is set to inverted u-shaped, the middle part of fixed block arranges dial gauge, the downside of fixed block arranges standard gauge block, the lower end of dial gauge arranges connecting link, connecting link links together by jackscrew and dial gauge, measuring head is welded on connecting link, the lower end of measuring head arranges dip stick.
Dip stick described in the utility model, is characterized in that dip stick is set to sounding rod and measures two kinds of sheets, and the diameter of sounding rod is set to Φ 0.2～3mm, and the thickness of measuring sheet is set to 0.06～0.5mm.
Fixed block described in the utility model, is characterized in that fixed block center arranges the hole of a Φ 10mm and the rectangular through slot that length and width are respectively 20mm and 35mm.
The utility model has the advantages that simple in structurely, be easy to carry, easy operating, measuring accuracy is high, has solved flat-bottom hole and inaccurate, the inconvenient problem of narrow groove defectoscopy.
