Abstract

The utility model provides a measurement micrometer for depth of a surface defect of a steel plate. The head of a measuring rod adopts a sharp cone. When the micrometer is used, the bottom plate of the micrometer is tightly attached to the surface of the steel plate to be measured, the measuring rod is aligned with the defect to be measured, and when the measuring rod cannot be driven by a rotary force measuring device to move further, the depth of the defect to be measured can be calculated through totaling a reading on a fixed sleeve and a reading on a micro tube. Therefore, the defect with the diameter more than 1mm on the surface of the steel plate can be measured accurately, and reliable data can be provided for evaluation and treatment of such defects caused by wax coating, pitting and pressing of iron scales. Compared with the round-head or flat-head measuring rod, the sharp-head measuring rod has the advantages of good stability, high accuracy and high adaptability.

Description

Surface Defects in Steel Plate depth survey milscale
Technical field
The utility model belongs to the appliance field, relates in particular to a kind of milscale that is used for accurately measuring the Surface Defects in Steel Plate degree of depth
Background technology
Stipulate among the GB GB-T1218-2004 that the sounding rod diameter of micrometric depth gauge is 3.5mm to 6mm, measuring head is disc or plane.At present, the milscale of the employed measurement Surface Defects in Steel Plate of the steel rolling mill degree of depth
Figure 519355DEST_PATH_IMAGE001
, its sounding rod diameter is commonly 4.5mm, and measuring head is a round end.Therefore, less than the common pitting of the surface of steel plate of 4.5mm with hang defectives such as cured,, cause diameter can't measure for diameter less than the depth of defect of 4.5mm owing to circular measuring head can't be stretched into the defective bottom.Thereby make steel rolling mill can't carry out quantitative evaluation less than the defective that cured, the surperficial pitting of the extension of 4.5mm, iron scale such as are pressed at small size, therefore directly influenced order of accuarcy and the effect that defective is handled for the surface of steel plate diameter.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple, is convenient to operation, can accurately measure the milscale of surface of steel plate diameter greater than the depth of defect of 1mm And measuring method.
For this reason, the solution taked of the utility model is:
A kind of Surface Defects in Steel Plate depth survey milscale comprises sounding rod, base plate, locking device, fixed muffle, microdrum and device for measuring force, it is characterized in that, the head of cylindrical sounding rod is the tip cone.
The beneficial effects of the utility model are:
Owing to adopt the tip sounding rod, realized can accurately measuring greater than the depth of defect of 1mm for the common diameter of surface of steel plate, evaluation and processing that, pitting cured for hanging and iron scale such as are pressed at defective provide reliable data.Compare with round end or tack sounding rod, the good stability of tip sounding rod, the degree of accuracy height, adaptability is strong.The utility model makes full use of the critical piece and the function of standard depth milscale, just changes the shape of sounding rod measuring head, has just enlarged the scope of application of depth survey milscale, and is therefore simple, be convenient to operation, and measuring speed is fast.
Description of drawings
Accompanying drawing is a Surface Defects in Steel Plate depth survey milscale outside drawing.
Among the figure: sounding rod 1, base plate 2, locking device 3, microdrum 4, device for measuring force 5, fixed muffle 6.
Embodiment
By accompanying drawing as seen, depth survey milscale system is made up of sounding rod 1, base plate 2, locking device 3, microdrum 4, device for measuring force 5 and fixed muffle 6.The Surface Defects in Steel Plate depth survey milscale of the utility model mainly changes the measuring head of cylindrical sounding rod 1 into cone, makes measuring head have tip.
The concrete grammar of Surface Defects in Steel Plate depth survey and step are:
1, the microdrum 4 of rotation milscale makes in the sounding rod 1 retraction base plate that is connected on the microdrum 4.
2, milscale base plate 2 is close to tested surface of steel plate, sounding rod 1 is aimed at tested defective.
3, the microdrum 4 and the device for measuring force 5 of rotation milscale move the cone tip of sounding rod 1 gradually to the defective bottom.
4, when rotation device for measuring force 5 can not make sounding rod 1 continuation mobile, with the reading addition of reading on the fixed muffle 6 and microdrum 4, both sums were the degree of depth of tested defective.
