It is noted that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Referring to fig. 1 to 6, an embodiment of the present invention provides a gear machining precision detection device, which includes a detection platform 10, wherein one side of the detection platform 10 is provided with an image capturing mechanism 20, the other side is provided with a backlight assembly 30, and an image capturing end of the image capturing mechanism 20 is arranged towards the backlight assembly 30; the image capturing mechanism 20 is used for capturing image data of the gear, and the image capturing mechanism 20 includes a high resolution camera and lens capable of capturing in detail the surface features and possible imperfections of the gear. The backlight assembly 30 is located opposite the image capturing mechanism 20 to provide uniform background light, which helps to improve the image edge contrast of the gears, and to make the image processing analysis clearer and simpler.
A light source mechanism 40 is arranged between the image capturing mechanism 20 and the detection platform 10, and the light source mechanism 40 comprises an annular light source assembly 41 and a strip light source assembly 42 which are respectively arranged towards the detection platform 10.
It should be noted that the annular light source assembly 41 and the strip light source assembly 42 may be configured to provide different directions and forms of illumination. The annular light source can generate evenly distributed surrounding light to reduce shadows, and the strip light source can provide directional illumination to highlight the stereoscopic features of the gear.
The detection platform 10 is rotatably connected with a mounting head 11 for positioning a gear to be detected, and the mounting head 11 is connected with a rotary driving assembly 12; the mounting head 11 is used to secure the gear to be inspected and the rotary drive assembly 12 controls the rotation of the gear about its axis, allowing the gear to be observed and inspected from various angles.
At least one side of the mounting head 11 is provided with an induction component 13, the induction component 13 is provided with an induction gap 131, a rotating path of the gear to be detected passes through the induction gap 131, and the induction component 13 is used for detecting the rotating angle of the gear to be detected. The sensing assembly 13 serves to detect the number of gear teeth passing through the notch and the exact moment of passage, thereby precisely measuring the rotation angle of the gear. Thereby assisting in assessing the profile accuracy and tooth form accuracy of the gear.
The working principle of the invention is as follows: when the gear to be detected is mounted on the mounting head 11 during detection, the rotation driving component 12 drives the gear to be detected to rotate; in the gear rotation process, the image capturing mechanism 20 is combined with the backlight source assembly 30 to capture a high-contrast and high-definition gear image, and the annular light source and the strip light source assembly 42 provide uniform and specific-angle illumination for the gear, so that the image quality is further improved, and particularly, the detail part of the gear is further improved; the sensing component 13 monitors the rotation angle of the gear through the sensing notch 131 so as to record the defect position and angle of the gear; compared with the detection technology in the prior art, the detection device can provide stable and uniform light through the backlight source assembly 30, the annular light source and the strip light source assembly 42, effectively reduces the influence of the change of the ambient light on the detection result, and is beneficial to improving the detection precision; meanwhile, the rotating structure enables the gear to rotate comprehensively, the rotating angle is accurately monitored by matching with the sensing assembly 13, comprehensive analysis and detection of the gear are achieved, and detection capability of complex shapes is optimized.
In the present embodiment, the annular light source assembly 41 includes a first annular light source 411 and a second annular light source 412 disposed in this order; wherein the outer diameter of the first annular light source 411 is smaller than the inner diameter of the second annular light source 412. The two sets of annular light sources may provide multiple levels of illumination for the gear surface being inspected, the first annular light source 411 may provide a more concentrated light area, and the second annular light source 412 may provide a wider illumination range.
The collocation of the two annular light sources can generate different shadows and highlights on the gear, which plays a key role in highlighting the tiny features, defects or contours of the gear; different combinations of light rays may make it easier for image processing software to identify and measure these details.
As an alternative of this embodiment, the number of the strip light source assemblies 42 is two, and the two groups of strip light source assemblies 42 are respectively disposed above and below the detection platform 10; the strip light source assembly 42 comprises a lamp bead plate 421 which is arranged obliquely to the horizontal direction, and a plurality of lamp beads 422 are arranged on the lamp bead plate 421.
The two sets of strip light source assemblies 42 respectively above and below the detection platform 10 can provide light projected at multiple angles, which is beneficial to generating richer shadows and highlights, so that the geometric shape and detail characteristics of the gear surface are more obvious.
The lamp bead plate 421 that the slope set up makes light shine on the gear with certain angle, and this kind of inclination can reduce glare and the reflection that parallel illumination probably produced, helps improving the detail discernment ability of image, and then promotes the accuracy of detection.
Further, the number, brightness and distribution of the lamp beads 422 can be adjusted according to the requirement by using the lamp bead plate 421 formed by the lamp beads 422, so that the light source assembly can flexibly adapt to gear detection with different sizes and shapes. Illumination may be provided from multiple angles to facilitate different features of the protruding gear surface. The ring light source can uniformly emphasize the outline and surface detail of the gear by surrounding the gear, and the strip light source can provide directional illumination to enhance the shadow and texture in a specific direction, so that the identification of surface defects is facilitated.
In summary, compared with the light source scheme in the prior art, the light source combination mode (comprising the annular light source assembly, the strip light source assembly and the backlight source assembly) adopted by the gear machining precision detection device is beneficial to enhancing the stereoscopic impression, so that the image is not only a planar silhouette, but also has a depth three-dimensional representation, and more accurate assessment and measurement of the three-dimensional characteristics of the gear are facilitated.
All direct illumination lights (annular and strip light sources) are arranged on one side, and the strong reflection phenomenon caused by metal reflection can be reduced by adjusting the angle; (in gear machining detection, metal reflection may cause image overexposure, so that defects are difficult to identify), and the phenomenon can be effectively avoided or reduced by reasonably configuring the light source.
Specifically, the two sides of the light source mechanism 40 are respectively provided with an adjusting mechanism 50; the adjusting mechanism 50 comprises a guide pillar assembly 51 arranged along the vertical direction, a first connecting block 52 and a second connecting block 53 are arranged on the guide pillar assembly 51, the first connecting block 52 is connected with the first annular light source 411, and the second connecting block 53 is connected with the strip light source assembly 42; the first connecting block 52 is slidably connected to the guide pillar assembly 51, and the first connecting block 52 is provided with a locking member for positioning the first connecting block 52.
The first connection block 52 is connected to the first annular light source 411 and is slidable along the guide post assembly 51. The height of the first ring light source 411 can be adjusted up and down by sliding connection, thereby affecting the light distribution irradiated onto the gear; the locking member is designed to locate the first connector block 52 and can be used to fix the light source position when the operator finds the optimal light source position, ensuring stability and repeatability in the inspection process.
The second connecting block 53 is provided with a connecting hole, and an adjusting piece 54 is arranged in the connecting hole; one end of the adjusting member 54 is connected to the lamp bead plate 421 for adjusting an inclination angle of the lamp bead plate 421.
The second connecting block 53 is connected with the strip light source assembly 42, and an adjusting piece 54 is arranged in the connecting hole of the second connecting block; one end of the adjusting member 54 is connected to the lamp bead plate 421, and by adjusting these members, an operator can change the inclination angle of the lamp bead plate 421; the adjustable tilt angle allows the bar light source to illuminate light at different angles, which is advantageous for better viewing irregularities and detail features of the gear surface by changing the shadow and highlight areas.
In summary, the design of the adjustment mechanism 50 increases the flexibility of adjustment for the gear machining accuracy detection device, provides the possibility of being able to precisely position and adjust two different light sources, and in turn can optimize the lighting conditions for specific detection tasks and object features to be detected, thereby improving the accuracy and reliability of the detection results.
In the present embodiment, the image capturing mechanism 20 includes a mount 21, and two lens assemblies 22 are arranged side by side on the mount 21; the side-by-side configuration of the two lens assemblies 22 allows images to be captured from two different perspectives or focal distances simultaneously, i.e., for each side profile of the gear, thereby comprehensively inspecting the gear. For example, one lens may be used to capture a view of the entire gear of the macroscopic image, while another lens is used to capture microscopic details such as details of the tooth surface.
A first linear module 23 is arranged below the mounting table 21, and the driving end of the first linear module 23 is connected with the mounting table 21 and used for driving the mounting table 21 to move towards a direction approaching or separating from the detection platform 10. This design allows the lens assembly 22 to be positionally adjusted as needed to optimize shooting distance and angle to accommodate gears of different sizes and shapes.
The dual lens design and movable mounting 21 of the imaging mechanism 20 in this embodiment reduces the need to reposition gears or equipment to obtain different viewing angles and focal lengths, thereby improving the efficiency and speed of detection.

The probe assembly 66 is a high-precision sensor for contact detection to measure the flatness or other surface characteristics of the gear surface; by moving the probe assembly 66 along the gear surface and recording the readings, the detection device is able to obtain accurate data regarding the flatness of the gear surface. The probe mechanism 60 provides another detection means for the quality detection of the gear, which can be combined with the detection result of the optical detection data capturing mechanism 20 to provide a multi-aspect detection result; the integration can comprehensively detect surface defects, irregularities and tooth profile accuracy problems.
