To be checked.In addition, in the present embodiment, inner surface inspection device 1 is set as with control unit 11 and aftermentioned prison
The structure of visual organ 13, but control unit 11 and aftermentioned monitor 13 are also possible to the dress seperated with inner surface inspection device 1
It sets.
In the present embodiment, there are two second gas channels 62 for the tool of insertion device 10.Two second gas channels 62 with
Gas is discharged to mutually opposite direction centered on central axis 9.That is, two second gas channels 62 are configured at shell 4
In outer peripheral surface it is the distance between circumferential most far from.Thereby, it is possible to the internal diameters of more accurately measured hole 81.
< 1.2. is about flow chart >
Then, referring to Fig. 3 to use inner surface inspection device 1 inner surface inspection and internal diameter measure flow chart into
Row explanation.Fig. 3 is the flow chart for showing the flow chart in inner surface inspection device 1.
Firstly, insertion device 10 is inserted into the hole 81 of checked property 8 (step ST101).Next, operator is to slotting
The position for entering utensil 10 is finely adjusted, and makes the position alignment (step ST102) in the hole 81 of insertion device 10 and checked property 8.This
When, so that the end of insertion device 10 is configured at the entrance in hole 81.
Next, control unit 11 makes insertion device 10 carry out inner surface inspection process while end side is mobile in the axial direction
(step ST103).That is, moving the end of inner surface inspection device 1 internally from the entrance in hole 81, pass through camera on one side
2 photographing element 22 shoots the inner surface in hole 81.Image data is stored in control unit 11.
Then, control unit 11 makes the base end side movement in the axial direction of insertion device 10 on one side, carries out internal diameter measurement process (step on one side
Rapid ST104).That is, making the end of inner surface inspection device 1 mobile from the inside in hole 81 to Way on one side, on one side in progress
Diameter measures process.It is imported specifically, gas is imported into gas via pressure/voltage converter section 122 from gas supply source 121
Portion 63, control unit 11 calculate the internal diameter S111 in hole 81 according to the pressure of the gas measured in pressure/voltage converter section 122.
The internal diameter data in calculated hole 81 are stored in control unit 11.
Then, after inner surface inspection process and internal diameter measurement process terminate, insertion device 10 is removed from checked property 8
(step ST105).
Alternatively, it is also possible to carry out inner surface inspection process and internal diameter measurement process simultaneously.
In this way, without using separated device but being able to use a device by using inner surface inspection device 1 and carrying out
Inner surface inspection and internal diameter measurement.Thus, it is possible to only carry out once being equivalent to being detected for step ST101 and step ST102
It looks into object 8 and is set to the process of device and the process for removing checked property 8 of step ST105, therefore improve operating efficiency.
Also, in the present embodiment, camera 2 can be directly inserted in checked property 8.Therefore, and using light
The inspection method of reflection etc. is compared, and can more precisely be checked.Also, with using light reflection inspection the case where not
Together, it does not need for can be realized inner surface inspection dress for the light irradiation light source in the inner surface reflection of checked property 8
Set 1 miniaturization.Moreover, because the camera 2 with photographing element 22 is directly inserted in checked property 8, therefore operator
Insertion device 10 can be held to be checked.Moreover, because camera 2 has shell 21 and is protected by camera cover 3, therefore i.e.
Expose camera 2 from shell 4, also can be avoided can not be checked because of breakage etc..
Moreover, first gas passage 61 is set between camera cover 3 and shell 4.Therefore, by not changing the kind of camera 2
Class and the outer diameter for adjusting camera cover 3, can adjust the diameter of first gas passage 61.
2. variation > of <
More than, the illustrative embodiment of the utility model is illustrated, but the technical program does not limit
In above-mentioned embodiment.
Fig. 4 and Fig. 5 is the cross-sectional view of insertion device 10 involved in variation.In the example of Fig. 4, camera 2 and phase
The axial position in the axial end portion of hood 3 and the axial position in axial end portion of shell 4 are identical.In this case, can
Protect the axial end of camera 2 and camera cover 3.Wherein, " identical " herein is also comprising roughly the same.
Also, the O-ring 7 for the axial end side for closing first gas passage 61 can also be made to be located at the shell 21 of camera 2
Between shell 4.O-ring 7 is an example of the application " the second elastomeric element ".
Also, camera 2 is not limited to be bonded with the fixing means of camera cover 3.In the example of Fig. 4, it can also pass through on one side
It rotates camera cover 3 centered on central axis 9, camera 2 is inserted in camera cover 3 comes fixed camera 2 and camera cover 3 on one side
(being fixedly clamped).Also, as shown in figure 5, the calking in the calking portion 35 of axial end side of camera cover 3 can also be made to be fixed on phase
Machine 2.
Moreover, inner surface inspection device 1 can also not have camera cover 3.Fig. 6 is the insertion device 10 without camera cover
Cross-sectional view.In this embodiment, first gas passage 61 is set between the shell 21 of camera 2 and shell 4.In this case, energy
Number of components is enough reduced, cost of implementation reduces.
Also, size and shape of each component etc. are not limited to the content of above-mentioned embodiment, can be according to quilt
It checks shape or the diameter in the hole 81 of object 8 etc. and suitably changes.For example, being set as the outer diameter of cylindrical portion 42 than base end part 41
The small structure of outer diameter, but size relation may be reversed.Also, the quantity in second gas channel 62 is two, but can also
To be one or three or more.In the case where multiple second gas channel 62 are arranged, can centered on central axis 9 edge
It is circumferential to configure at equal intervals, it can also unequally configure.
In addition, the shape in the subtle portion about inner surface inspection device, it can also be different from each attached drawing of the application.And
It, can also be by each element occurred in above-mentioned embodiment or variation suitably and in the range of not generating contradiction
Combination.
