Description
Technical field
The present invention relates to detect field of tool, more particularly to a kind of quick and precisely detection part pit defect depth dimensions
Detecting tool.
Background technology
Aero-Space and all kinds of parts of relevant industries easily produce all kinds of pit defects in process, are producing and are testing
During receipts, such pit defect depth dimensions often decides the final whether qualified judgement of product, so seeming very heavy
Will.
When particularly being detected to the pit defect depth dimensions on heavy parts, the accuracy of measurement seems particularly critical,
So big in face of measurement error, the problems such as heavy parts middle part defect detection equipment range is limited, never one it is good
Solution.
In actual production, usually detected by the way of segmental support and dial gauge are combined at present, due to arch
Frame structure, specification and range are limited, and segmental support span is 500mm, and back gauge cannot be detected more than 500mm, particularly large-scale wall
Plate, melon valve, top cover, the pit defect depth dimensions of covering middle part, cause accuracy of detection low, are not easy to operation, Zhi Nengtong
Cross repeatedly measurement and try to achieve average value, error is larger, and efficiency is low.In addition, pit defect has spy different, not of uniform size
Point, pit is probably hemispherical, back taper, stairstepping, triangle, irregular shape, defect bottom and mouth diameters, shape, big
Small to differ, sonigauge cannot also be detected because of reasons such as probe diameter sizes, to lacking more than 500mm pits away from edge
Fall into accuracy of detection low, never good detection method.
The pit defect depth dimensions near part edge is detected using point micrometer, when pit defect position
During in Central of the parts position, often need to change different survey tools, when the close pars intermedia on several meters of heavy parts
During the pit defect of position, just cannot be detected.
Using other ask the method for approximation but must less than accurate measured value, to the judgement of product quality bring compared with
Big difficulty, is seeking a good detection method always.
The content of the invention
The purpose of the present invention is that the detecting tool for providing a kind of quick and precisely detection part pit defect depth dimensions,
To solve the above problems.
To achieve these goals, the technical solution adopted by the present invention is such：A kind of quick and precisely detection part pit lacks
Fall into the detecting tool of depth dimensions, including dial gauge, measurement pipe and measuring probe, the tail of the dial gauge and the measuring probe
Portion is connected, and the measuring probe main body is located in measurement pipe, and the head of the measuring probe is tapered, the top of the measurement pipe
Screwed hole and the lock-screw coordinated with the screwed hole are provided with, the bottom of the measurement pipe is provided with supporting leg.
As preferred technical scheme：The measuring probe is two, and one of measuring probe is in similar to " Z " word
Shape.One of them is direct rod shape, for conventional detection, and can be used to measure cavity narrow and small similar to " Z " font measuring probe
Or have the pit defect at interference position.It is described to have referred to perpendicular section, crosspiece and head and had three sections altogether similar to " Z " font,
What first place was formed by connecting, wherein, the perpendicular section is in 90 ° or so with crosspiece, and head is in 90 ° of left sides in the other end and crosspiece of crosspiece
The right side, and erect the not homonymy of section and head in crosspiece.
As preferred technical scheme：The dial gauge is connected than the tailing screw flight of the measuring probe, is conveniently installed, is torn open
Unload and receive.
As preferred technical scheme：The number of the supporting leg is three or four.
The application method of frock of the invention is identical with the conventional use of dial gauge, first measuring probe is stretched out triangle or
The length of quadrangle supporting leg is adjusted, and it is slightly larger than pit defect depth dimensions and meets dial gauge maximum range, then
Do not have defective position small change beside pit defect, dial gauge then moves to defective locations and measures reading.Measurement cambered surface,
The position of supporting leg should put consistent with small change position during pit defect on sphere, ellipsoid, and Z-shaped measurement head is used for measuring chamber
Body is narrow and small or has the pit defect at interference position.
Compared with prior art, the advantage of the invention is that：
1st, improve accuracy of detection：Take with dial gauge with detection instrument is combined into, reduce detection error, improve detection
Precision, its accuracy of detection can reach 0.01mm, compared to existing accuracy of detection 0.05, improve 5 times；
2nd, improve detection efficiency：One man operation（2 people are needed to operate when using larger segmental support）, detection is once completed, survey
Influence of the segmental support gravity to measured value on dial gauge need not be removed in amount, detection efficiency improves more than 50%；
3rd, it is applied widely：Suitable for the detection of all kinds of part pit defect depth dimensionses, versatility is good.
4th, measurer low cost of manufacture：General tool steel, material usage is few, clever structure；
Quick accurate detection just can effectively be carried out using this composite detection tool, simple to operate, versatility is good, improves zero
Part detection efficiency and accuracy, make the easy of the judgement change of product, it is possible to replace traditional detection method, such as segmental support is to this
The detection of class pit defect depth dimensions.
