Abstract
The utility model discloses a bonding magnetic ring detects and advises with ladder PIN, its characterized in that: comprise the integration of the cylindrical PIN of multistage rule pretext to tail, each section outer diameter pretext to tail that PIN advised scales up, constitutes the gradient, the integration is provided with the lead -over groove between adjacent two sections PIN rule, afterbody on ladder PIN rule is provided with the handle. The utility model discloses a ladder PIN rule have the calibration effect to product circularity, and the detection accuracy is high, the test error is little, and maneuverability is strong.
Description
Technical field
This utility model is related to a kind of PIN rule, and in particular to a kind of PIN rule for being detected to the magnet ring that bonds.
Background technology
Bonding magnet ring is typically all that technique productions using PM technique with reference to compression molding are formed, therefore or it is many or
There are certain plastic deformation and elasticity less, especially thin-walled magnet ring.When detecting to the bond internal diameter of magnet ring, external diameter at present
Conventional survey tool is adopted all, for example slide calliper rule, digimatic micrometer etc., on the one hand as magnet ring sheet is produced in pressing process
Certain circularity, on the other hand due to taking the difference of a position in test process, can all cause measurement error, affect measurement knot
Really.Further, since these survey tools can cause certain extruding in measurement to product, measurement error equally can be also produced.
Utility model content
In order to solve the above problems, the utility model discloses a kind of bonding magnet ring detection is advised with ladder PIN, it is intended to avoid
Measurement error, raising certainty of measurement.
This utility model solves technical problem, adopts the following technical scheme that：
This utility model bonding magnet ring detection is advised with ladder PIN, and its feature is：The ladder PIN rule are justified by multistage
From first to last integration is constituted cylindricality PIN rule, and the outside dimension of each section of PIN rule is incremented by from the head to the tail, constitutes gradient；Adjacent two sections
Between PIN rule, integrated setting has lead-over groove；The afterbody of ladder PIN rule is provided with handle.
Size difference 0.005-0.01mm for ensureing certainty of measurement, between adjacent two sections of PIN rule.The hop count root of PIN rule
According to need arrange.
The groove depth of the lead-over groove is 0.5-1.0mm, groove width is 0.5-1.0mm.
For ease of the magnet ring measurement that bonds, it is rounded down in the end face of PIN rule.
The PIN rule are formed by a circular bar overall processing, and bar can be using tool steel, high-speed steel or hard
The hardness such as matter steel alloy are high, anti abrasive alloy material is constituted.The detection faces of the PIN rule will have higher fineness, generally
It is required that surface roughness is not more than 0.02 μm.Because PIN rule are formed by a circular bar overall processing, the groove width of lead-over groove
For 0.5-1.0mm, that is to say adjacent two sections of PIN rule at intervals of 0.5-1.0mm；Groove depth is 0.5-1.0mm, can be lead-over groove
External diameter compared to external diameter (i.e. maximum outside diameter) the little 0.5-1.0mm that most afterbody PIN is advised, while ensure lead-over groove external diameter be less than
The external diameter of most head PIN rule.
Compared with the prior art, the beneficial effects of the utility model are embodied in：
1st, ladder PIN of the present utility model rule have calibration function to product circularity, so dimensional accuracy is high, test error
It is little；
2nd, high using ladder PIN of the present utility model rule detection efficiencies, repeatability, repeatability are good；
3rd, ladder PIN rule of the present utility model are workable；
4th, ladder PIN rule of the present utility model have the function of go-no go gauge and measurement data simultaneously concurrently；
5th, thin-walled magnet ring being enclosed within ladder PIN rule of the present utility model can also carry out the measurement of product external diameter, measure number
It is little according to error.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Labelling in figure：1 advises for PIN；2 is lead-over groove；3 is handle.
Specific embodiment
As shown in figure 1, it is of the present utility model bonding magnet ring detection with ladder PIN rule, be by multistage cylinder PIN advise 1 from
Head is constituted to tail integration, and the outside dimension of each section of PIN rule is incremented by from the head to the tail, constitutes gradient；One between adjacent two sections of PIN rule
Body is provided with lead-over groove 2；The afterbody of ladder PIN rule is provided with handle 3.
Size difference 0.005-0.01mm for ensureing certainty of measurement, between adjacent two sections of PIN rule.For ensureing measurement phase
Do not influence each other between adjacent two sections of PIN rule, the groove depth of lead-over groove 2 is set to 0.5-1.0mm, groove width (between adjacent two sections of PIN rule
Distance) be set to 0.5-1.0mm.
Enter for ease of bonding magnetic ring set, be rounded down in the end face of PIN rule 1.The surface roughness of PIN rule 1 is not more than
0.02μm。
Using the ladder PIN rule of the present embodiment to the method detected by the magnet ring that bonds it is：By thin-walled to be checked bonding magnet ring
The head (i.e. size smallest end) that product is advised from ladder PIN starts to be inserted in, and passes sequentially through each section of PIN rule, if on a certain section of PIN rule
Cannot be inserted in, the PIN scales that product is located cun are just product hole size.Now, the cooperation that product is advised with corresponding PIN is more
Closely, the circularity of product is minimum, therefore the magnet ring external diameter that can also be enclosed within slide calliper rule or miking on PIN rule, measures number
Value is more accurate.
