Abstract
The utility model discloses a steel product surface local defect depth and height measuring apparatus, comprising a micrometer, the lower end of the micrometer is respectively provided with a measuring probe and a transparent sleeve; and the opening caliber at the lower end of the transparent sleeve is larger than the external diameter at the lower end of the micrometer. The measuring apparatus has simple structure and convenient use and can fast measure concave or convex defects on the surface of the steel products.
Description
Technical field
The utility model belongs to the improvement of micrometer caliper measuring apparatus structure, relates to dark, the height-gauge of a kind of steel part surface local defective.
Background technology
The kind of milscale is a lot, but can be effective to also not having at present of local defect dark (height) degree measurement.Particularly to the detection of the projection on detected member surface and depression equidimension, utilize general testing tool to detect comparatively difficulty, influence is judged normally.
The utility model content
The purpose of this utility model is to provide a kind of steel part surface local defective dark, height-gauge, and it is simple in structure, can effectively measure steel part depression in the surface or protruding defective, measures efficient and convenient.
The purpose of this utility model is achieved in that a kind of steel part surface local defective is dark, height-gauge, comprise milscale, the lower end of milscale vertically is being provided with measuring probe and transparent sleeve respectively, and the lower ending opening bore of transparent sleeve is greater than the lower end external diameter of milscale.
The utility model is simple in structure, during use, the transparent sleeve of milscale lower end is affixed on the measured object surface, to determine reference field.Rotating milscale then makes the measuring probe of its lower end contact with the bottom of depression or the top of projection, can read corresponding numerical value by milscale, thereby determine the height of cup depth or projection, measure steel part depression in the surface or protruding defective quickly, convenient to use.
The utility model is used to detect the projection of steel plate and coil of strip local defect and the numerical value of depression, and measuring accuracy is 0.002 millimeter.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the main TV structure synoptic diagram of the utility model embodiment 1;
Fig. 2 is the main TV structure synoptic diagram of the utility model embodiment 2.
Embodiment
A kind of steel part surface local defective is dark, height-gauge, as shown in Figure 1 and Figure 2, comprises milscale 1, and the lower end of milscale 1 vertically is being provided with measuring probe 2 and transparent sleeve 3 respectively.
Can observe moving axially of measuring probe 2 easily by transparent sleeve 3, guarantee correctly projection or pit defect to be positioned, guarantee measurement accuracy.
Accurate screw rod in measuring probe 2 and the milscale 1 links to each other, utilizes accurate thread pair principle, and accurate screw rod rotates in the nut of milscale, and measuring probe 2 just moves relative to transparent sleeve 3 along axis.
The lower ending opening bore of transparent sleeve 3 is greater than the lower end external diameter of milscale 1.
Like this, during use, the lower surface of transparent sleeve 3 can fully contact with the measured object surface, thereby effectively determines reference field.
Said transparent sleeve 3 is cylinder barrel shaped or prismatic tubular or semisphere.
Said transparent sleeve 3 is for being made of glass or organic plastics or resin material.
Claims (3)
1, dark, the height-gauge of a kind of steel part surface local defective comprises milscale, and it is characterized in that: the lower end of milscale vertically is being provided with measuring probe and transparent sleeve respectively, and the lower ending opening bore of transparent sleeve is greater than the lower end external diameter of milscale.
2, dark, the height-gauge of steel part surface local defective according to claim 1, it is characterized in that: said transparent sleeve is cylinder barrel shaped or prismatic tubular.
3, dark, the height-gauge of steel part surface local defective according to claim 1 and 2 is characterized in that: said transparent sleeve is for being made of glass or organic plastics or resin material.
