Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0034] like Figure 1-3As shown, this utility model discloses a tool measuring device, including a detection mechanism 100 and a tool clamping mechanism 200. The detection mechanism 100 includes a detection table 10, on which a first camera 20 for detecting the end face of the tool and a second camera 30 for detecting the periphery of the tool are provided. A first ring light source 40 and a second ring light source 50 are sequentially arranged on the object side of the first camera 20 along its imaging direction. A third ring light source 60 and an auxiliary light source 70 are sequentially arranged on the object side of the second camera 30 along its imaging direction. During detection, the axis of the tool coincides with the axes of the first ring light source 40 and the second ring light source 50. The third ring light source 60 and the auxiliary light source 70 are located on opposite sides of the tool's periphery. By sequentially arranging the first ring light source 40 and the second ring light source 50 on the object side of the first camera 20, and the third ring light source 60 and the auxiliary light source 70 on the object side of the second camera 30, the tool can be illuminated according to measurement needs, improving image clarity and thus detection accuracy. Simultaneously, the number of detection items is increased, allowing multiple items to be detected simultaneously on one machine, reducing enterprise production costs.
[0035] In this invention, the testing platform 10 is provided with a first mounting base 21, which is adjustablely mounted on the rear side of the testing platform 10 via a first adjusting component 22. The first camera 20 is mounted on the first mounting base 21. The first adjusting component 22 can be used to adjust the up / down and left / right positions of the first camera 20 as needed, so that the position of the first camera 20 is consistent with the position of the tool to be tested. The testing platform 10 is provided with a second mounting base 31, which is adjustablely mounted on the right side of the testing platform 10 via a second adjusting component 32. The second camera 30 is mounted on the second mounting base 31. The second adjusting component 32 can be used to adjust the up / down and front / back positions of the second camera 30 as needed, so that the position of the second camera 30 is consistent with the position of the tool to be tested. The second mounting base 31 is provided with a support base 33 and a detection drive mechanism 34 that drives the support base 33 to move along the imaging direction of the second camera 30. The second camera 30 is mounted on the support base 33. During testing, the second camera 30 can be moved by the testing drive mechanism 34 to adjust the distance between the second camera 30 and the tool under test. Specifically, the testing drive mechanism 34 is a servo motor. During testing, the servo motor can precisely control the movement of the second camera 30 to place the tool in the optimal imaging position, improving testing accuracy. It should be understood that the testing drive mechanism 34 can also be replaced by an electric cylinder. It should be understood that in this utility model, the second camera 30 is located on the right side of the testing platform 10, but in actual use, it can also be located on the left, upper, or lower side of the testing platform 10 as needed.
[0036] Specifically, the upper end of the detection platform 10 is provided with a slide rail 11 extending along the imaging direction of the first camera 20. The slide rail 11 is provided with a first slide block 42 and a second slide block 52. A first light source bracket 41 and a second light source bracket 51 are respectively provided on the first slide block 42 and the second slide block 52. The first ring light source 40 and the second ring light source 50 are respectively mounted on the first light source bracket 41 and the second light source bracket 51. The first slide block 42 is provided with a first locking bolt 43 for fixing the first slide block 42 to the slide rail 11, and the second slide block 52 is provided with a second locking bolt 53 for fixing the second slide block 52 to the slide rail 11. In use, the first locking bolt 43 or the second locking bolt 53 can be loosened, allowing the first slide block 42 or the second slide block 52 to slide relative to the slide rail 11. This allows for adjustment of the positions of the first ring light source 40 and the second ring light source 50 as needed, providing better illumination for the first camera 20 and improving detection accuracy.
[0037] In this utility model, the detection platform 10 is also provided with a third light source bracket 61 and a light source mounting base 71. The third light source bracket 61 is adjustablely mounted on the object side of the second camera 30 through a third adjustment component 62. The third ring light source 60 is mounted on the third light source bracket 61, and the auxiliary light source 70 is mounted on the light source mounting base 71, with the illumination direction of the auxiliary light source 70 facing the side of the third ring light source 60.
[0038] Specifically, the first light source bracket 41, the second light source bracket 51, and the third light source bracket 61 are all provided with plate-shaped side-standing mounting parts, and each mounting part is provided with through holes. The axis of the through holes on the first light source bracket 41 and the second light source bracket 51 coincides with the axis of the first annular light source 40 and the second annular light source 50. The axis of the through hole on the third light source bracket 61 is consistent with the shooting direction of the second camera 30. During detection, the first camera 20 can take pictures of the end face and peripheral contour of the tool through the through holes on the first light source bracket 41 and the second light source bracket 51, and the second camera 30 can take pictures of the peripheral surface of the tool through the through hole on the third light source bracket 61.
[0039] It should be noted that in this utility model, the first adjustment component 22, the second adjustment component 32 and the third adjustment component 62 are all micrometer push adjustment mechanisms commonly used in the field, and their specific structures will not be described here.
[0040] In this invention, the tool clamping mechanism 200 includes a material transfer module 220 disposed beside the inspection table 10 and a clamping assembly 210 controlled by the material transfer module 220 to move toward the inspection table 10. A rotary drive mechanism 230 is fixedly provided at the drive end of the material transfer module 220. The clamping assembly 210 is connected to the output end of the rotary drive mechanism 230 and is controlled by the rotary drive mechanism 230 to rotate so that the tool on the clamping assembly 210 changes from a vertical to a horizontal orientation. In this invention, the clamping assembly 210 and the rotary drive mechanism 230 are conventional structures readily conceived by those skilled in the art, and will not be described in detail here.
[0041] During inspection, the tool to be inspected is first clamped and fixed by the clamping assembly 210, either manually or by machine. The rotation drive mechanism 230 drives the clamping assembly 210 to rotate, changing the tool's orientation from vertical to horizontal. The transfer module 220 then drives the clamping assembly 210 to move towards the inspection table 10, allowing the tool to pass through the first ring light source 40 and the second ring light source 50. The first camera 20 takes a picture of the end face of the tool, and the second camera 30 takes a picture of the peripheral surface of the tool. It should be noted that in this embodiment, the tool is transferred to the inspection mechanism 100 for inspection by moving the clamping assembly 210. In actual use, the inspection mechanism 100 can also be moved to the tool clamping mechanism 200 by controlling the movement of the inspection table 10, thereby inspecting the tool at the tool clamping mechanism 200.
[0042] In summary, this utility model, by sequentially setting a first ring light source and a second ring light source on the object side of the first camera, and sequentially setting a third ring light source and an auxiliary light source on the object side of the second camera, can illuminate the tool according to measurement needs, improve image clarity, and increase detection accuracy, enabling the tool detection accuracy to reach ±1μm; at the same time, it increases the number of detection items, allowing multiple items to be detected simultaneously on one machine, reducing enterprise production costs.
[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
