Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiment of the present invention is elaborated.
See Fig. 2, Fig. 3 and Fig. 8, workpiece biside plate upper annular part larger diameter internal bore axiality detection device of the present invention,
Including major axis 1, measure bar 2, bearing 3 and detection platform 4.From Fig. 2, Fig. 3 and Fig. 8, described bearing 3 has two, and they can
Adjusting the setting of axial spacing ground to be upwards supported in detection platform 4, the height adjusting degree ground, two ends of described major axis 1 is respectively with two
The top of individual bearing 3 is connected, and described measurement bar 2 is vertical with major axis 1, and its inner can rotate around major axis 1 and can be axial along major axis 1
It is slidably connected on major axis 1, the length of its outer end to the axial line of major axis 1 and the radius value of the larger diameter internal bore of annular element
Equal and shape is also corresponding cylindrical arc, the vertical dimension of the axial line of described major axis 1 to the upper surface of detection platform 4 with
The radius value of the larger diameter internal bore 71 of annular element 70 adds that the wall thickness value of annular element 70 adds the bottom of annular element 70
Equal to the height sum of bottom surface of base plate 72 of workpiece 7.Therefore, the present invention can be in accordance with the following steps to 7 liang of side rings of workpiece
The axiality of the larger diameter internal bore 71 of shape part 70 detects.See Fig. 8 and Fig. 9；First, the base plate 72 of workpiece 7 is placed
In the detection platform 4 of the present invention, and workpiece 7 is made to be integrally located between two bearings 3 of the present invention；Then, make the present invention's
Major axis 1 is in the state outside the outer end of the larger diameter internal bore 71 that its two ends stretch out in both sides annular element 70；Then, along major axis
1 rotationally, move axially measurement bar 2, such as, from left to right along major axis 1 rotationally, move axially measurement bar 2, make measurement bar
Move in the larger diameter internal bore 71 of 2 first any one annular element 70 backward；The axle center of outer end to major axis 1 owing to measuring bar 2
The length of line is equal with larger diameter internal bore 71 radius of annular element and the axial line of described major axis 1 is to the upper table of detection platform 4
With the radius value of the larger diameter internal bore 71 of annular element 70, the vertical dimension in face adds that the wall thickness value of annular element 70 adds ring
The bottom of shape part 70 is equal to the height sum of the bottom surface of the base plate 72 of workpiece 7.Therefore, as long as measuring bar 2 energy on major axis 1
Within enough larger diameter internal bore 71 the most axially movably moving into each annular element 70, it is possible to determine workpiece 7 liang
In the range of the axiality of the larger diameter internal bore 71 of the annular element 70 on side plate 73 is in reasonably.Otherwise, as long as measuring bar 2 and existing
Within can not the most axially movably moving into the larger diameter internal bore 71 of any one annular element 70 on major axis 1, just
May determine that the axiality of the larger diameter internal bore 71 of the annular element 70 on workpiece 7 biside plate 73 is in irrational scope.
Therefore, the present invention detect more convenient, detection efficiency is higher, detection relatively accurately, do not have error, it is possible to ensure workpiece 7
In use reach requirement, and enable the special machine equipment of this workpiece 7 of assembling normally to work.
