Another end top fix testing tool for smoothness；The end face of column measurer is less than the internal diameter of the through hole of reducing gearbox,
The end face of column measurer is set to be placed on the upper surface of annular projection, the height of column measurer is equal to the upper of the annular projection of through hole
Distance d1 in the end face vertical direction of end face and through hole；Testing tool for smoothness is depth calibrator, the spy of depth calibrator
Pin straight down and is fixed on the lower section of L-type fixed mount, and the distance of lower end to the upper surface of support platform of probe is whole for workpiece
The vertical height d2 of body.
To contact the contact surface of workpiece, upper table is interval with groove downwards for the upper surface of support platform.
Constant resistance post on L-type fixed mount on the outside of probe, stop that the lower surface of post is higher than the syringe needle of probe.
Two sides all constant resistance posts of L-type fixed mount.
Relative to prior art, technique effect of the present utility model is, the utility model will detect length be converted into it is smooth
The measurement of degree, detection speed is fast, precision is high.Simple to operate, the time is short.

Embodiment
Such as Fig. 2-3, a kind of detection means of reducing gearbox, including support frame, column measurer and testing tool for smoothness.
Support frame includes the support platform 2 of ring-type, and at least three perpendicular supports 21 are fixed in the lower section of support platform 2, and support is flat
The upper surface of platform 2 matches with the flange 14 of workpiece, and on the upper surface for making support platform 2, the side of support platform 2 is fixed L-type and consolidated
Determine the end of frame 3, testing tool for smoothness is fixed on the top of another end of L-type fixed mount 3.
The end face of column measurer 4 is less than the internal diameter of the through hole 11 of reducing gearbox 1, the end face of column measurer 4 is placed on ring
On the upper surface of shape projection 12, the height of column measurer 4 is equal to the upper surface and the end of through hole 11 of the annular projection 12 of through hole 11
Distance d1 in the vertical direction of face.
Testing tool for smoothness is depth calibrator 31, and the probe 32 of depth calibrator 31 straight down and is fixed on L-type
The lower section of fixed mount 3, the distance of lower end to the upper surface of support platform 2 of probe 32 is the overall vertical height d2 of workpiece.
It is in its operation principle：
It is such as Fig. 1-3, the through hole 11 of workpiece is upward when needing detection, it is supported on support platform 2 entirely through flange 14
On, column measurer 4 is placed on being placed on the upper surface of annular projection 12 of through hole 11, because the height of column measurer 4 is equal to through hole
The upper surface of 11 annular projection 12 and the distance d1 in the end face vertical direction of through hole 11, so, if column measurer 4 is upper
End face and the upper surface 13 of the hole wall of through hole 11 are exactly certified products in a plane, are not otherwise just certified products.
Because through hole 11 is not on the center of workpiece, when most starting, such as Fig. 3, through hole 11, depth calibrator 31 are wrong
Opening is put.
Then, effect depth calibrator 31, make the distance of lower end to the upper surface of support platform 2 of probe 32 whole for workpiece
The vertical height d2 of body, now the reading of depth calibrator 31 is " zero ".
Then workpiece is rotated around the axis of support platform 2, make the contact probe 32 of upper surface 13 of the hole wall of through hole 11
Bottom, the reading of depth calibrator 31 is judged whether in ± 5, if certainly, the overall vertical height d2 of workpiece
Qualified, otherwise, workpiece is unqualified.Write down the reading A of now depth calibrator 31.
Turning of work piece is further continued for, makes the bottom of the end contact probe 32 of column measurer 4, writes down now depth calibrator
31 reading B, reading A, reading B difference are judged whether in ± 5, if certainly, the annular projection 12 of workpiece through-hole 11
Upper surface and the distance d1 in the end face vertical direction of through hole 11 it is qualified, otherwise, workpiece is unqualified.
So, once-through operation is just completed and detected at two, and efficiency is higher.
When workpiece rotates phase mutual friction in support platform 2, iron filings can be produced, and iron filings pad can influence to survey therebetween
Accuracy of measurement, therefore, such as Fig. 4, the upper surface 23 of support platform 2 is the contact surface of contact workpiece, and upper surface 23 is interval with downwards
Groove 24, groove 24 are used for storing iron filings, improve measurement accuracy.
Such as Fig. 5, if d1, d2 error are larger（It is exactly the telescopic extensions that the error has highly exceeded probe）, work as workpiece
When support platform 2 rotates, workpiece can break probe 32, therefore, constant resistance post on the L-type fixed mount 3 in the outside of probe 32
33, stop that the lower surface of post 33 is higher than the syringe needle of probe 32.
Such as Fig. 6, two sides all constant resistance posts 33 of L-type fixed mount 3, can protect when positive hour hands, rotate counterclockwise
Shield.
Other guide participates in prior art.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
