Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and can not be construed to of the present utility model
Limitation.
As shown in Figure 1 to Figure 2, embodiment of the present utility model provides a kind of nut location degree measurement servicing unit, bag
Locating piece 1 and locating rod 2 are included, the first end of the locating rod 2 is fixed on the first end of the locating piece 1, the locating rod 2
The internal diameter of external diameter and nut to be measured at the second end match, the first end of the locating piece 1 is bonded with the top surface of nut to be measured,
Second end of the locating piece 1 is formed with positioning reference plane 3.
The diameter of locating rod 2 is too small to cause positioning precision to reduce, and the diameter of locating rod 2 crosses conference causes locating rod 2
Difficulty is taken out, wear phenomenon for a long time also be present.Therefore, the diameter of locating rod 2 is mostly to survey nut internal diameter, and the locating rod 2 is inserted
During the nut to be measured, the axial line of the nut to be measured overlaps with the axial line of the locating rod 2.
On positioning reference plane 3, mark can have been done, on the extension line for the axial line that this mark is located at the locating rod 2,
Measuring apparatus is to survey nut location degree by measurement markers.
In order that measuring apparatus can be rapidly and efficiently the axle center line position to locating rod 2 measure, while be also
Mark and the axial line of the locating rod 2 are completely superposed, and the positioning reference plane 3 is hemisphere face, the axis of the locating rod 2
Extended the hemispherical center, hemispherical sphere centre is on the extension line for the axial line for falling within locating rod 2, so may be used
