Embodiment
For ease of better understanding the purpose of this utility model, structure, feature and effect etc., now with specific embodiment, the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, the utility model relates to a kind of inwall panoramic imaging device of small, annular workpiece, comprise: a bracing frame 1, support frame as described above 1 comprises a support bar 10, be installed on one first support 11 on described support bar 10, be installed on one second support 12 on described support bar 10 and be installed on one the 3rd support 13 on described support bar 10, described second support 12 is positioned at the below of described first support 11, described 3rd support 13 is positioned at the below of described second support 12, be installed on the camera fixed block 2 on described first support 11, be fixed on the camera 3 on described camera fixed block 2, be installed on the shadowless lamp 4 on described second support 12, be fixed on the base 7 below support frame as described above 1, described base 7 is provided with a mount pad 70 for installing a conscope 6, support frame as described above 1 and described base 7 are all fixed on a worktable (not shown).
As shown in Figure 1, described first support 11, described second support 12 and described 3rd support 13 all can move up and down along described support bar 10; Described camera fixed block 2 can move horizontally along described first support 11; Described shadowless lamp 4 can move horizontally along described second support 12; Described 3rd support 13 is that a clamping limb is for clamping a workpiece for measurement 5.
As shown in Figure 1, described camera 3 is industrial camera, and be fixed on described camera fixed block 2 by screw, described camera 3 connects a computing machine (not shown), and computing machine carries out processing to the photo that described camera 3 is taken and stores.In the form of a ring, light color is white to described shadowless lamp 4, and intensity of light can regulate according to actual needs.Described workpiece for measurement 5 is small, annular workpiece, and during detection, described conscope 6 enters in described workpiece for measurement 5, and there is gap on described workpiece for measurement 5 and described conscope 6 surface.
Principle of work of the present utility model is as follows:
As shown in Figure 2, if the horizontal width of the imaging annulus of the inwall of described workpiece for measurement 5 on described conscope 6 is r, if the internal bore radius of described workpiece for measurement 5 be R, the height of described workpiece for measurement 5 is H, the tapering of described conscope 6 is α.Because described camera 3 is vertical shootings, so the reflection ray CB of workpiece for measurement 5 inwall is parallel with the axis OG of described conscope 6, so ∠ BCG=α, according to the principle of reflection of light, ∠ ACD=α, again because AE is parallel to OG, so ∠ AED=α, namely triangle AEC is isosceles triangle, AC=AE=H, triangle ABF is similar to triangle CDF, so ∠ BAF=α, AF=2*H*sin α, AB=r, cos α=AB/AF, release cos α=r/ (2*Hsin α), i.e. r=H*sin2 α, due to r<R, then H*sin2 α≤R, according to R, the difference of H value, also corresponding change can be there is in the tapering α value of conscope 6, two kinds of situations below point:
1, as H≤R, H*sin2 α≤R perseverance is set up, and α is acute angle, gets α=45 °, and namely during r=H, r gets maximum value.Namely now imaging is more clear, more complete.
2, as H>R, can in the hope of α=pi/2-1/2*arcsin (R/H), from the formula of α, now α is obtuse angle; Or α=1/2*arcsin (R/H), from the formula of α, now α is acute angle; So r=R now, be maximal value.
The method using the inwall panoramic imaging device of described small, annular workpiece to carry out imaging comprises following steps:
Step one: as shown in Figure 3, described workpiece for measurement 5 internal bore radius R=10mm, height H=10mm, the tapering α of described conscope 6 is calculated according to principle of work of the present utility model, by the tapering of corresponding computing formula determination conscope 6 be 45 ° (because the endoporus of described workpiece for measurement 5 exists depth problem, in order to imaging effect is better, so the tapering getting described conscope 6 should be 45 °≤α≤50 °), then the conscope 6 designed is arranged on described base 7.
Step 2: described base 7 is connected with bolt with support frame as described above 1.
Step 3: described workpiece for measurement 5 is installed on described 3rd support 13, make described workpiece for measurement 5 and described conscope 6 coaxial cable, moving up and down described second support 12 makes described conscope 6 be deep into the inside of described workpiece for measurement 5, and keeps described workpiece for measurement 5 to have gap with described conscope 6 surface.
Step 4: described shadowless lamp 4 is installed on described second support 12, move horizontally described shadowless lamp 4, move up and down described second support 12 simultaneously, described shadowless lamp 4 is adjusted to directly over described workpiece for measurement 5, keep described shadowless lamp 4 and described workpiece for measurement 5 coaxial cable, open described shadowless lamp 4.
Step 5: described camera 3 is connected with screw with described camera fixed block 2, then described camera fixed block 2 is installed on described first support 11, move horizontally described camera fixed block 2, move up and down described first support 11 simultaneously, described camera 3 is adjusted to directly over described workpiece for measurement 5 and described conscope 6, keep described camera 3 and described workpiece for measurement 5 coaxial cable, make the camera of described camera 3 be placed on the centre of described shadowless lamp 4 light, open camera 3.
Step 6: according to step 3, four, five corresponding regulative modes, adjust described conscope 6, described workpiece for measurement 5, described shadowless lamp 4, the right alignment of described camera 3 and vertical range.
Step 7: the image shown above according to the computing machine be connected with described camera 3, regulates the focal length of described camera 3, and adjust the intensity of described shadowless lamp 4 light, make imaging more complete display.
Step 8: the inwall panorama sketch taking described workpiece for measurement 5, disposable formation complete inwall clearly panoramic picture, finally with the inwall panoramic picture captured by computer disposal, analysis and storage.
More than describe the explanation being only preferred embodiment of the present utility model in detail, non-ly therefore limit to the scope of the claims of the present utility model, so the equivalence techniques change that all utilization the utility model instructionss and diagramatic content are done, is all contained in the scope of the claims of the present utility model.
