DETAILED DESCRIPTION
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0026] The utility model discloses a bearing detection device, which comprises a bearing flow channel 10 and an image acquisition mechanism 20.
[0027] Reference Figure 1 and Figure 2 As shown, in the bearing detection device of the utility model, the bearing flow channel 10 is used to transport the bearing. The bearing flow channel 10 is provided with a detection station 102. When the bearing moves to the detection station 102, the image acquisition mechanism 20 acquires an image of the bearing to realize defect detection.
[0028] There are multiple image acquisition mechanisms 20, and the multiple image acquisition mechanisms 20 are arranged around the detection station 102. Those skilled in the art can set the images that need to be collected by the specific image acquisition mechanism 20 according to actual needs, so as to detect different defects. The surrounding structure makes full use of the space and avoids mutual interference between the image acquisition mechanisms 20, thereby improving the space utilization rate and ensuring the detection accuracy.
[0029] Each image acquisition mechanism 20 includes a focus adjustment component and an image acquisition part 22. Among them, the focus adjustment component includes a fixed seat 211 and a rotating seat 212. The fixed seat 211 is fixedly arranged; preferably, the fixed seat 211 is fixed by bolts. The rotating seat 212 is rotatably connected to the fixed seat 211, and the pitch angle of the image acquisition part 22 is adjusted by the rotating seat 212 that can rotate relative to the fixed seat 211. The image acquisition part 22 is used to capture the image of the bearing on the detection station 102. Those skilled in the art can set a specific image acquisition part 22 according to actual needs, such as an area array camera. The image acquisition part 22 is movably connected to the rotating seat 212, and the moving direction of the image acquisition part 22 is perpendicular to the extension direction of the axis of the rotating shaft of the rotating seat 212. Preferably, an image acquisition slide rail 2122 is provided on the rotating seat 212, the image acquisition member 22 is connected to the image acquisition slider 2123, and the image acquisition slider 2123 is movably connected to the image acquisition slide rail 2122 to realize the movable connection between the image acquisition member 22 and the rotating seat 212. By setting up this structure, it can be ensured that under the premise of changing the pitch angle, the distance of the image acquisition member 22 relative to the bearing to be detected can be adjusted by relatively moving the image acquisition member 22 and the rotating seat 212.
[0030] During actual inspection, bearings of the same type move along the bearing flow channel 10. When a bearing moves to the inspection station 102, the image of the bearing is acquired through the image acquisition component 22, and the acquired image is analyzed in combination with a computer to determine the defect of the bearing. When the bearing type changes, the staff can change the pitch angle of the image acquisition component 22 by rotating the seat 212, and change the relative front and rear position of the image acquisition component 22 by moving the image acquisition slider 2123, so as to achieve focus without adjusting the parameters of the image acquisition component 22 itself. The structure is simple, which reduces the requirements for the staff, facilitates rapid focus, improves inspection efficiency, and facilitates maintenance by the staff.
[0031] The bearing detection device described in the utility model sets the image acquisition component 22 on the focus adjustment component. When the bearing type changes, the staff can change the pitch angle of the image acquisition component 22 by rotating the seat 212, and change the relative front and rear position of the image acquisition component 22 by moving the image acquisition slider 2123, so as to achieve focus without adjusting the parameters of the image acquisition component 22 itself. The structure is simple, which reduces the requirements for the staff, facilitates the rapid realization of focus, and improves the detection efficiency. A plurality of image acquisition mechanisms 20 are arranged around the detection station 102. The surrounding structure makes full use of the space and avoids mutual interference between the image acquisition mechanisms 20, thereby improving the space utilization rate and ensuring the detection accuracy.
[0032] Reference Figure 2As shown, in some embodiments of the bearing detection device described in the utility model, an arc groove 2121 is provided on the rotating seat 212, and the arc groove 2121 extends along the circumferential direction of the axis of the rotating shaft of the rotating seat 212. Those skilled in the art can set the specific arc length of the arc groove 2121 according to actual needs, so as to meet different pitch angle adjustment requirements. The focus adjustment assembly also includes a locking member, which passes through the arc groove 2121 and is connected to the fixed seat 211. The locking member is not shown in the accompanying drawings; preferably, the locking member is configured as a combination of a bolt and a nut. When the locking member is locked, the rotating seat 212 can be prevented from rotating relative to each other; when the locking member is loosened, the rotating seat 212 can rotate, thereby adjusting the pitch angle of the image acquisition member 22. The structure is simple and effective, and its purely mechanical structure is particularly suitable for relatively harsh bearing detection environments.
[0033] Preferably, the slider 2123 and the slide rail 2122 are provided with scales, which are not shown in the drawings. By setting the scales, it is convenient for the staff to use the scales as a reference during debugging to achieve rapid adjustment. Those skilled in the art can set up guide rail clamps according to actual needs to lock the slider and the slide rail to prevent them from moving at will.
[0034] Reference Figure 3 As shown, in the bearing detection device described in the utility model, in some embodiments, the bearing flow channel 10 is tilted. By tilting the bearing flow channel 10, it is convenient for the bearing to slide along the flow channel by its own gravity when moving, which saves energy and reduces costs. Preferably, the inclination angle of the bearing flow channel 10 relative to the horizontal plane is 5 to 10 degrees. When the inclination angle is too small, less than 5 degrees, it is too gentle, the bearing movement speed is low, and the efficiency is reduced. When the inclination angle is too large, greater than 10 degrees, it is too steep. Although the bearing movement speed is increased, it also increases the difficulty of positioning the bearing. Those skilled in the art can set the inclination angle of the specific bearing flow channel 10 according to actual needs, such as 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, etc.
[0035] Further, see Figure 3As shown, in the bearing detection device described in the utility model, in some embodiments, the bearing flow channel 10 includes a first flow channel section 101 and a second flow channel section 103 arranged at intervals, and the detection station 102 is arranged between the first flow channel section 101 and the second flow channel section 103. A bearing positioning assembly is provided on the detection station 102 to position the bearing and provide a rotational driving force for the bearing at the same time, so as to facilitate defect detection. Specifically, the bearing positioning assembly includes two rotatable support rollers 31, and the support rollers 31 rotate to drive the bearing located between the two support rollers 31 to rotate synchronously. Preferably, the two support rollers 31 are connected to support the driving motor 32 to achieve rotational drive; of course, in other embodiments, the drive can also be achieved by setting gears, synchronous belts, etc. By setting the support rollers 31, it is convenient to position the bearing when the bearing moves between the support rollers 31 and prevent it from continuing to move along the flow channel. At the same time, when performing image acquisition, the bearing can be driven to rotate by the support rollers 31, so that the first image acquisition mechanism 201 can collect radial end surface images of different positions of the bearing without moving.
[0036] Further, see Figure 3 As shown, the bearing detection device described in the utility model, in some embodiments, further includes a lifting component, which is arranged below the support roller 31 and located between the two support rollers 31 on one side close to the first flow channel section 101. The lifting component includes a lifting drive component 41 and a lifting component 42, and the lifting component 42 is connected to the driving end of the lifting drive component 41. Those skilled in the art can set the lifting drive component 41 according to actual needs, such as a cylinder. Preferably, the lifting component 42 is set as a roller, and its circular structure can be well adapted to a circular bearing. In actual use, the bearing moves along the bearing flow channel 10 to between the two support rollers 31. After completing the corresponding image acquisition, the lifting component 42 can provide an eccentric lifting force for the positioned bearing to enter the second flow channel section 103. After completing the jacking, the lifting component 42 is reset to prevent interference with subsequent bearings. This structure can quickly and effectively realize the jacking of the bearing.
[0037] Further, see Figure 3As shown, the bearing detection device described in the utility model, in some embodiments, further includes two limit assemblies 50. Along the extension direction of the bearing flow channel 10, the two limit assemblies 50 are respectively arranged on both sides of the detection station 102 to ensure that the bearing located on the first flow channel section 101 or the second flow channel section 103 will not interfere with the bearing located on the detection station 102. Each limit assembly 50 includes a limit drive component 51 and a limit component 52, and the limit component 52 is connected to the driving end of the limit drive component 51. Those skilled in the art can set the limit drive component 51 according to actual needs, such as a cylinder. Preferably, the limit assembly 50 is arranged below the corresponding flow channel section, making full use of the space below the flow channel and improving the space utilization rate. When image acquisition is required, the limit drive component 51 drives the limit component 52 to rise to separate the bearings; after the acquisition is completed, the limit drive component 51 drives the limit component 52 to descend to allow the corresponding bearing to pass. Preferably, the limit component 52 is set as a roller, and its outer surface is coated with rubber to provide buffering. The round shape of the rollers can act as auxiliary wheels, allowing the bearings to pass over them.
[0038] Reference Figure 3 and Figure 4 As shown, in the bearing detection device described in the utility model, in some embodiments, the bearing flow channel 10 includes a bearing support plate 11 and a bearing limiting component 12. Two bearing limiting components 12 are provided, and the two bearing limiting components 12 are respectively arranged on both sides of the bearing support plate 11. In actual use, the bearing moves on the bearing support plate 11, and its axial sides are limited by the bearing limiting components 12. Among them, at least one bearing limiting component 12 can be relatively close to or relatively far away from another bearing limiting component 12. By setting this structure, bearings of different axial sizes can be effectively adapted to improve versatility. Preferably, a size adjustment component 13 is provided to simultaneously adjust the distance between the two bearing limiting components 12. Preferably, the size adjustment component 13 is used to adjust the distance between the two bearing limiting components 12 through a threaded structure; of course, in some other embodiments, the distance can also be adjusted by a cylinder or a slide rail structure, which will not be repeated.
[0039] Further, see Figure 4 As shown, in the bearing detection device described in the utility model, in some embodiments, a limiting rod 121 is provided on the bearing limiting component 12. Preferably, two parallel limiting rods 121 are provided on each bearing limiting component 12. By providing the limiting rods 121, the bearing can be effectively limited to avoid problems such as falling during the movement of the bearing.
[0040] Reference Figure 5As shown, in some embodiments of the bearing detection device of the utility model, the image acquisition mechanism 20 includes a first image acquisition mechanism 201, a second image acquisition mechanism 202, a third image acquisition mechanism 203, a fourth image acquisition mechanism 204 and a fifth image acquisition mechanism 205. The first image acquisition mechanism 201 is arranged on the bearing flow channel 10, and the image acquisition member 22 of the first image acquisition mechanism 201 is used to acquire the radial end face image of the bearing on the detection station 102. The second image acquisition mechanism 202 and the third image acquisition mechanism 203 are relatively arranged on both sides of the detection station 102, and the image acquisition member 22 of the second image acquisition mechanism 202 and the image acquisition member 22 of the third image acquisition mechanism 203 are both used to acquire the groove image of the bearing on the detection station 102; it should be noted that, taking the ball bearing as an example, the groove refers to the groove where the ball is placed in the bearing. Along the extension direction of the bearing flow channel 10, the fourth image acquisition mechanism 204 is arranged on the side of the second image acquisition mechanism 202 close to the second image acquisition mechanism 202 close to the first image acquisition mechanism 201. Along the extension direction of the bearing flow channel 10, the fifth image acquisition mechanism 205 is arranged on the side of the third image acquisition mechanism 203 away from the first image acquisition mechanism 201. The image acquisition member 22 of the fourth image acquisition mechanism 204 and the image acquisition member 22 of the fifth image acquisition mechanism 205 are both used to acquire the chamfer image of the bearing on the inspection station 102.
[0041] Reference Figure 1 As shown, the bearing detection device described in the utility model, in some embodiments, further includes a light source component 60, which is arranged above the detection station 102. The light source component 60 is used to provide supplementary light and illumination for the image acquisition mechanism 20. Preferably, the light source component 60 is arranged as a surface light source.
[0042] Working principle:
[0043] During the inspection, the bearing to be inspected moves along the bearing support plate 11 of the first flow channel section 101. When it moves to the support roller 31, the bearing is trapped between the two support rollers 31 and is positioned and cannot move. At the same time, the two limit drive components 51 drive the limit components 52 to rise to separate the bearings on the front and rear sides. The support roller 31 rotates, driving the bearing to rotate; with the assistance of the light source component 60, each image acquisition mechanism 20 acquires the corresponding image of the bearing, and analyzes the acquired image in combination with a computer to achieve defect detection.
[0044] When the type of bearing changes, the staff does not need to adjust the parameters of each image acquisition component 22. Instead, the focus of the image acquisition component 22 can be achieved by adjusting the pitch angle of the rotating seat 212 and moving the image acquisition slider 2123.
[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
