Among them, the annular light source is an important accessory in the image measuring machine.

[0003] Generally, when a batch of annular light sources are used in an image measuring machine, it is usually necessary to ensure that when the same type of annular light source has the same brightness value set in the software, its brightness performance tends to be consistent, improving the consistency of the imaging effect of the surface light. At present, for a large number of annular light sources produced, there are differences in the brightness performance of a small part when the same brightness value is set, which will affect the measurement accuracy of the subsequent image measuring machine. In order to ensure the measurement results of the image measuring machine and the portability after writing the measurement program in the software, and improve the measurement efficiency. Therefore, there is an urgent need for an inspection tooling structure for an image measuring machine to meet the requirements during measurement. Summary of the Utility Model

Specific implementation manner

[0017] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Refer to Figure 1 , an inspection tooling structure of an image measuring machine, including: a base plate 11; an integrated illuminometer 9, which is arranged on the top of the base plate 11, and a limiting mechanism for fixing it on the base plate 11 is arranged at the outer end of the integrated illuminometer 9; a measuring structure, which includes a lens camera 6 and a ring light source 7, the centers of the lens camera 6 and the ring light source 7 are concentrically arranged along the radial direction with the photosensitive component of the integrated illuminometer 9, and a fixing mechanism for fixing it above the integrated illuminometer 9 is arranged at the upper end of the measuring structure. An inspection tooling for specifically inspecting a type of ring light source is designed. An integrated illuminometer 9 is designed directly below the ring light source 7 to be measured. When the same brightness value is set through software, by detecting the brightness performance emitted by the ring light source 7 through the integrated illuminometer 9, the brightness result of the currently detected ring light source 7 can be known. Then, a batch of ring light sources of the same type can be detected in sequence, without having to install them on a specific image measuring machine to inspect the brightness, reducing the duration of the debugging work. The consistency of the inspection results of the ring light brightness is further ensured through a professional integrated illuminometer device, which is worthy of promotion.

[0019] It should be mentioned that the entire detection tooling is also externally connected to a console (not shown in the figure) that can set the same brightness value, and the entire console is externally connected to a power supply.

[0020] Furthermore, the limiting mechanism includes a support block 10, a knurled screw 13 and several positioning blocks 8. The several positioning blocks 8 are respectively arranged on the adjacent sides of the integrated illuminometer 9, and the support block 10 is arranged on the other side of the integrated illuminometer 9. The position of the integrated illuminometer 9 can be limited through the cooperation of the multiple positioning blocks 8 and the support block 10, so that its photosensitive component can be centered on the ring light source 7 to be measured, thereby ensuring the overall detection accuracy.

[0021] Further, the end of the positioning block 8 is arc-shaped and abuts against the outer end face of the integrated illuminance meter 9. A waist-shaped slot is provided in the positioning block 8 along its length direction. Both ends of the support block 10 are provided with mounting holes. The positioning block 8 and the support block 10 are respectively fixed on the bottom plate 11 by screws passing through the waist-shaped slot and the mounting holes. Threaded holes corresponding to the waist-shaped slot and the mounting holes are provided on the bottom plate 11. A hollow tightening block 12 is provided on the other end face of the support block 10. A second threaded hole coaxial with the hollow hole of the tightening block 12 is provided in the support block 10. A knurled screw 13 passes through the tightening block 12 and is threadedly connected to the support block 10. The inner end face of the knurled screw 13 abuts against the outer end face of the integrated illuminance meter 9. At the same time, the present utility model can also adjust the position of the photosensitive component of the integrated illuminance meter 9 according to different types of annular light sources. During adjustment, by designing a waist-shaped slot in the positioning block 8, the left-right and front-back positions of the positioning block 8 can be correspondingly adjusted, and then the adjustment can be made according to the center position of different types of annular light sources. After adjusting the position, it can be fixed by using the knurled screw 13 correspondingly, which can also ensure the overall applicability.

[0022] Further, the fixing mechanism includes a column 15, a guide rail 16, a camera connecting plate 4 and a light source mounting plate 5. The column 15 is detachably mounted on the top side of the bottom plate 11 in the vertical direction. The guide rail 16 is detachably mounted on the end face of the column 15 facing the integrated illuminance meter 9 in the vertical direction. A slider 2 capable of sliding up and down along it is provided on the guide rail 16. The camera connecting plate 4 is integrally in a "U" shape. The lens camera 6 is detachably mounted on the outer end face of the camera connecting plate 4. The inner end face of the camera connecting plate 4 facing the guide rail 16 is detachably mounted on the outer end face of the slider 2. The light source mounting plate 5 is detachably mounted on the bottom end face of the camera connecting plate 4. The upper end face of the annular light source 7 is fixed on the bottom end face of the light source mounting plate 5. A through hole is provided at the center position of the bottom end face of the light source mounting plate 5 for the annular light source 7. Through the cooperation of the camera connecting plate, the light source mounting plate 5 and the guide rail 16, the X-direction and Y-direction positions of the measuring structure can be defined. At the same time, since the annular light source 7 and the light source mounting plate 5 are detachably connected, after the current annular light source 7 is detected, the current annular light source 7 can also be removed and replaced with other annular light sources 7 for detection, so as to realize the batch detection of the annular light source 7.

[0023] Further, the fixing mechanism further includes an L-shaped plate 3 and a rubber gasket 1. The rubber gasket 1 is attached to the side surface of the column 15. One end of the L-shaped plate 3 is detachably mounted on the inner end face of the camera connecting plate 4. A fastening screw 17 tightly abuting against the outer end face of the rubber gasket 1 is threadedly connected to the other end of the L-shaped plate 3, which is used to define the Z-axis position of the measuring structure. Through the cooperation of the guide rail 16 and the slider 2, the Z-direction position of the measuring structure can be adjusted to achieve the purpose of clear central imaging of the photosensitive component of the integrated illuminance meter 9. After the adjustment is completed, the fastening screw 17 can be locked towards the rubber gasket 1 to realize the locking of the measuring structure in the Z direction.

[0024] Among them, all the main components are detachably installed, so that each component can be individually removed and replaced when damaged or maintained.

[0025] It should be noted that the detachable installation method mentioned in the present utility model is preferably a fixing method using bolts or screws, but it is not limited herein.

[0026] Furthermore, handles 14 are detachably installed at both ends of the top of the bottom plate 11, and the inspection tooling can be conveniently carried to the desired position by means of the handles 14.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
