Description
Technical field
A kind of measurement apparatus is the utility model is related to, more particularly, to a kind of portable piece surface microsize defect
Measuring instrument.
Background technology
At present, known depth gauge rule measurement head cross section is relatively large, and for small rut on metal flat, (diameter is less than
3mm) etc the defects of, can not accurately be measured.Contourgraph directly by certain evaluation criteria reading or can depict surface
The shape of contour curve, measurement accuracy is higher, but the size to measuring workpiece has size requirement, and workpiece can only be put into work
Measured on platform, be inconvenient to measure for larger workpiece (such as main bearing of shield machine lasso) and when needing instrument taking scene.
Small rut on metal flat（Impression, load mould, corrosion hole etc.）Or small projection（Corrosion projection etc.）Etc the defects of degree of injury not
It is easy to be evaluated by specific data, easily causes false judgment.
The content of the invention
The utility model purpose is to provide a kind of portable piece surface microsize defectoscopy instrument, can not for overcoming
The problem for the defects of measuring small rut (diameter is less than 3mm).
The purpose of this utility model can be achieved through the following technical solutions.The described small chi of portable piece surface
Very little defectoscopy instrument includes switch magnetic seat, cross slid platform, overarm brace, pointed chaining pin, reference pin, dial gauge, in switch magnetic
One cross slid platform is set on power seat, overarm brace is arranged on cross slid platform, and dial gauge and reference pin are set on overarm brace,
Pointed chaining pin is set on dial gauge.
Described reference pin is arranged on the overarm brace bottom on the inside of pointed chaining pin, and reference pin is parallel with pointed chaining pin to be set
Put.
The termination of described pointed chaining pin is the bullet that diameter is less than 0.05mm, reference pin be when being used to measure workpiece
Measuring basis is determined on workpiece.
The utility model can do upper and lower, left and right straight line by using cross slid platform work top in perpendicular and transport
It is dynamic, adjust the reference pin being fixed on cross slid platform work top and the pointed chaining pin of dial gauge is touched near measured surface defect
Coplanar flat region, while dial gauge registration is adjusted to zero, pass through the pointed chaining pin of cross slid platform horizontal adjustment dial gauge to surface
Defect minimum point or peak, while ensure the tested coplanar flat region of reference pin contact, then dial gauge needle deflection zero graduation
Registration be exactly surface defect depth or height.In summary, the utility model can facilitate to small rut on metal flat（Pressure
Trace, load mould, corrosion hole etc.）Or small projection（Corrosion projection etc.）Etc the defects of damage measure.And small volume, measurement
Precision height (0.01mm), to measuring workpiece strong applicability, conveniently take in-site measurement.And evaluated by data, it will not cause
False judgment.

Embodiment
Illustrate specific embodiment of the utility model below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, described portable piece surface microsize defectoscopy instrument includes switch magnetic
Seat 7, cross slid platform 6, overarm brace 2, pointed chaining pin 3, reference pin 4, dial gauge 1, set a cross on switch magnetic seat 7
Slide unit 6, overarm brace 2 are arranged on cross slid platform 6, dial gauge 1 and reference pin 4 are set on overarm brace 2, in dial gauge 1
Upper to set pointed chaining pin 3, wherein pointed chaining pin 3 and reference pin 4 are each perpendicular to overarm brace 2, overarm brace 2 is fixed on cross cunning
On the work top of platform 6, ensure that rigid beam support 2 is parallel with tested plane, the benchmark table top of cross slid platform 6 is fixed on switching regulator magnetic
On power seat 7, ensure that overarm brace 2 can be logical with the work top of cross slid platform 6 vertical motion and horizontal movement, switching regulator magnet base 7
Cross magnetic force and be close to tested plane (pit or raised burnishing surface nearby), realize the benchmark table top of fixed cross slide unit 6, adjust during measurement
Switching regulator magnet base 7 makes pointed chaining pin and reference pin 4 be adjacent to the burnishing surface near tested pit or projection, and adjustment dial gauge 1 refers to
Pin registration is 0, and moving horizontally pointed chaining pin 3 makes stylus needle contact pit lowest part or raised highest point while ensure reference pin
4 are adjacent to the burnishing surface near pit or projection, then the registration of the scale of 1 needle deflection of dial gauge 0 is the depth or projection of pit
Height, so as to reach the purpose of accurate measurement metal surface microsize depth of defect or height.
