[0018] 1.

[0020] 3. By installing the rotating assembly, four top visual inspection cameras and the first cylinder, the inspection disk drives the clamped shaft hardware to pass through four outer surface inspection positions in sequence. After the gear at the inner end of the telescopic tube passes through the corresponding arc-shaped tooth plate, the clamped shaft hardware is rotated 90° through the telescopic tube and the abutment tube, and then turned to the bottom of the top visual inspection camera, and the image of the top half side is captured for processing and analysis.

[0021] 4. By installing the side vision inspection camera, focusing tube, reflection component and light beam, for the inspection of inner surface defects of hollow shaft hardware, when it turns to the inner surface inspection position, the electric slide rail drives the side vision inspection camera to move radially, driving the focusing tube and the reflection component through the opening into the shaft hardware. The light emitted by the light beam passes through the telescopic tube and the anti-tube into the shaft hardware, and is evenly reflected circumferentially by the second conical reflector to form a halo on the inner wall of the shaft hardware. The light of the halo is reflected into the focusing tube by the first conical reflector, and finally the circumferential inner wall of the halo segment is photographed by the side vision inspection camera, and the radial movement is coordinated to complete the entire inner surface inspection process.

[0022] 5. By installing the discharge port, the third spring, the pull rod, the discharge port and the control component, after the U-shaped holder is turned to the loading position, the power socket contacts the corresponding power head, and the controller energizes the corresponding second spring to shrink it, which can shrink the push tube to facilitate the placement of shaft hardware. When it is turned to the discharge position, the controller controls the push tube to shrink again to release the shaft hardware. At the same time, according to the test results, the corresponding third spring is controlled to be energized and shrink, and the connecting rod is pulled to the corresponding side by the pull rod, and then the arc-shaped support plate is moved to the corresponding side, corresponding to the corresponding end of the shaft hardware. The shaft hardware in the released state can tilt to the side without support due to uneven force at both ends, and fall to the corresponding discharge port through the discharge port, completing the sorting process of defective products.

[0035] A height-adjustable arc-shaped support plate 13 is installed in the middle of the U-shaped holder 10, and a vertical second cylinder 38 is fixedly installed on both sides of the mounting column 2. The telescopic end of the second cylinder 38 is fixedly connected to an annular plate 39 sleeved on the mounting column 2, and the top of the annular plate 39 is rotatably connected to a lifting plate 41 sleeved on the periphery of the mounting column 2. The bottom of the detection plate 1 is fixedly connected to a plurality of guide rods 40 passing through the lifting plate 41. The bottom of the arc-shaped support plate 13 is connected to the lifting plate 41 through a connecting assembly, and the connecting assembly includes a connecting rod 3 fixedly connected to the bottom of the arc-shaped support plate 13. 1. The bottom of the U-shaped holder 10 and the bottom of the placement groove 9 are both provided with a discharge port 12 for the connecting rod 31 to pass through. The lower end of the connecting rod 31 is fixedly connected to a C-shaped frame 36. The two ends of the C-shaped frame 36 are slidably connected to the lifting plate 41 through a pair of slideways 45. A pair of second cylinders 38 are started to drive the annular plate 39 to rise and fall, and then the lifting plate 41 drives the multiple connecting components to rise and fall, thereby driving the multiple arc-shaped supporting plates 13 to rise and fall synchronously, and always keeping the axis of the shaft hardware corresponding to the axis of the outer plate 28 and the inner plate 26, so as to adapt to shaft hardware of different diameters.

[0036] The inner end of the U-shaped holder 10 is elastically mounted with a push tube 11, and the end of the push tube 11 is fixedly mounted with an inner push plate 26. The outer end of the U-shaped holder 10 is rotatably connected with an outer push plate 28 corresponding to the inner push plate 26. Under the elastic force of the second spring 24, shaft hardware is clamped by the inner push plate 26 and the outer push plate 28, thereby adapting to shaft hardware of different lengths.

[0037] Furthermore, a mounting ring 3 sleeved on the periphery of the detection disk 1 is fixedly connected to the base 37, and a first cylinder 8 is radially installed on the side walls of the mounting ring 3 corresponding to the four outer surface detection positions 7, and the telescopic end of the first cylinder 8 is adapted to the U-shaped holder 10. A plurality of telescopic tubes 14 are rotatably connected to the circumferential inner side of the detection disk 1, and the telescopic ends of the telescopic tubes 14 extend into the corresponding placement grooves 9 and are rotatably connected to the corresponding U-shaped holder 10. A first spring 25 is elastically installed in the telescopic tube 14, and the U-shaped holder 10 is pushed radially by the first cylinder 8, thereby driving longer shaft hardware to pass in sections directly under the top visual inspection camera 22, thereby completing the inspection process of longer shaft hardware.

[0038] A base 37 is installed below the detection disk 1, and a mounting column 2 extending to the center of the detection disk 1 is fixedly connected at the center of the base 37. A rotating assembly that can drive the abutment tube 11 to rotate 90° is installed at the top of the mounting column 2 corresponding to the four outer surface detection positions 7. The rotating assembly includes four arc-shaped toothed plates 15 fixedly installed at the top of the mounting column 2 in the circumferential direction. The four arc-shaped toothed plates 15 correspond to the four outer surface detection positions 7 one by one. The inner side end of the telescopic tube 14 is fixedly connected to a gear 16 that cooperates with the arc-shaped toothed plate 15. The telescopic end of the telescopic tube 14 passes through the first The two springs 24 are elastically connected to the abutment tube 11. After the gear 16 at the inner end of the telescopic tube 14 passes through the corresponding arc-shaped tooth plate 15, the telescopic tube 14 and the abutment tube 11 can only radially expand and contract, and cannot rotate relative to each other. The clamped shaft hardware is rotated 90° through the telescopic tube 14 and the abutment tube 11, and then rotated to the bottom of the top visual inspection camera 22, and the image of the top half side is captured for processing and analysis. It passes through four arc-shaped tooth plates 15 in turn, and the four half sides of the shaft hardware are separately photographed and inspected, thereby completing the entire outer surface inspection process.

[0039] A top plate 23 is installed above the inspection disk 1, and top visual inspection cameras 22 are installed on the top plate 23 corresponding to the four outer surface inspection positions 7. The camera only needs to take photos of a single side each time, and there is no need for continuous rotation and continuous shooting, which greatly improves the image processing efficiency.

[0040] An electric slide rail 21 is installed on one side of the inspection disk 1 corresponding to the inner surface inspection position 6, and a side vision inspection camera 19 is installed on the electric slide rail 21. A focusing tube 20 that can be inserted into the shaft hardware is fixedly installed on the shooting end of the side vision inspection camera 19, and a reflection component is installed on the end of the focusing tube 20. A light beam 18 adapted to the reflection component is fixedly installed at the top of the mounting column 2 corresponding to the inner surface inspection position 6. The reflection component includes a mounting rod 34 fixedly connected to the shooting end of the side vision inspection camera 19, and the mounting rod 34 extends out of the focusing tube 20 and is fixedly connected to a first conical reflector 33 and a second conical reflector 32. The second conical reflector 32 is directly opposite to the light beam 18, and the first conical reflector 33 is directly opposite to the light beam 18. For the focusing tube 20, an opening 29 for the focusing tube 20 to pass through is provided on the outer end of the U-shaped holder 10 and the outer abutment plate 28. The electric slide rail 21 drives the side vision inspection camera 19 to move radially, driving the focusing tube 20 and the reflection component to pass through the opening 29 and enter the shaft hardware. The light emitted by the light beam 18 passes through the telescopic tube 14 and the abutment tube 11 and enters the shaft hardware. It is evenly reflected circumferentially by the second conical reflector 32 to form a halo on the inner wall of the shaft hardware. The light of the halo is reflected into the focusing tube 20 by the first conical reflector 33, and finally the circumferential inner wall of the halo segment is photographed by the side vision inspection camera 19, and the radial movement is coordinated to complete the inspection process of the entire inner surface.

[0041] Furthermore, the cone angle of the first conical reflector 33 is 90°, and the cone angle of the second conical reflector 32 is 60°. The light beam 18 irradiating the second conical reflector 32 can be reflected to the circumferential position of the first conical reflector 33, and then reflected into the focusing tube 20 through the first conical reflector 33.

[0042] Furthermore, strip grooves are provided on both sides of the discharge port 12 at the bottom of the placement groove 9, and a pull rod 27 is elastically connected to the strip groove through a third spring 30. A pair of pull rods 27 respectively abut against both sides of the connecting rod 31. A control component for controlling the power on and off of the third spring 30 and the second spring 24 is installed on the detection disk 1. A pair of discharge ports 42 are provided at the position corresponding to the discharge port 12 on the lifting disk 41. The control component includes a plurality of groups of electrical connectors 44 embedded on the inner side wall of the detection disk 1. The plurality of groups of electrical connectors 44 are respectively electrically connected to the corresponding second springs 24 and a pair of third springs 30. The top of the mounting column 2 is connected to the upper material position 4 and the lower material position 5, respectively, and a power socket that cooperates with the power head 44 is installed. The power socket is externally connected to a controller, and according to the detection result, the corresponding third spring 30 is controlled to be energized and contracted, and the connecting rod 31 is pulled to the corresponding side by the pull rod 27, thereby moving the arc-shaped support plate 13 to the corresponding side, corresponding to the corresponding end of the shaft hardware. The shaft hardware in the released state can tilt to the side without support force due to uneven force on both ends, and fall to the corresponding lower material port 42 through the discharge port 12, completing the sorting process of defective products.

[0043] To adjust the height of the arc support plate 13 according to the diameter of the shaft hardware, it is only necessary to start a pair of second cylinders 38 to drive the annular plate 39 to rise and fall, and then drive multiple connecting components to rise and fall through the lifting plate 41, thereby driving multiple arc support plates 13 to rise and fall synchronously, and always keep the axis of the shaft hardware corresponding to the axis of the outer resistance plate 28 and the inner resistance plate 26. Under the elastic force of the second spring 24, the shaft hardware is clamped by the inner resistance plate 26 and the outer resistance plate 28, thereby adapting to shaft hardware of different lengths.

[0044] Start the servo motor 17, and drive the inspection disk 1 to rotate through the connecting frame 43, and drive the clamped shaft hardware to pass through the four outer surface inspection positions 7 in sequence. After the gear 16 at the inner end of the telescopic tube 14 passes through the corresponding arc-shaped tooth plate 15, since the telescopic tube 14 and the abutment tube 11 can only radially expand and contract, and cannot rotate relatively, the clamped shaft hardware is rotated 90° through the telescopic tube 14 and the abutment tube 11, and then rotated to the bottom of the top visual inspection camera 22, and the image of the top half side is captured for processing and analysis, and passes through the four arc-shaped tooth plates 15 in sequence, and the four half sides of the shaft hardware are separately photographed and inspected, and the entire outer surface inspection process can be completed. The camera only needs to take a single-sided photo each time, and there is no need for continuous rotation and continuous shooting, which greatly improves the image processing efficiency. The U-shaped holder 10 is pushed to move radially by the first cylinder 8, and the longer shaft hardware is driven to pass through the bottom of the top visual inspection camera 22 in sections, completing the inspection process of the longer shaft hardware.

[0045] For the detection of inner surface defects of hollow shaft hardware 35, when it moves to the inner surface detection position 6, the electric slide rail 21 drives the side visual inspection camera 19 to move radially, driving the focusing tube 20 and the reflective component to pass through the opening 29 into the shaft hardware. The light emitted by the light beam 18 passes through the telescopic tube 14 and the abutment tube 11 into the shaft hardware, and is evenly reflected circumferentially by the second conical reflector 32 to form a halo on the inner wall of the shaft hardware. The light of the halo is reflected into the focusing tube 20 by the first conical reflector 33, and finally the circumferential inner wall of the halo segment is photographed by the side visual inspection camera 19, and the entire inner surface inspection process is completed in coordination with the radial movement.

[0046] After the U-shaped holder 10 is rotated to the loading position 4, the power socket contacts the corresponding power head 44, and the controller energizes the corresponding second spring 24 to shrink it, thereby shrinking the push tube 11 to facilitate the placement of shaft hardware. When it is rotated to the unloading position 5, the controller controls the push tube 11 to shrink again to release the shaft hardware. At the same time, according to the detection result, the corresponding third spring 30 is controlled to be energized and shrink, and the connecting rod 31 is pulled to the corresponding side through the pull rod 27, thereby moving the arc-shaped support plate 13 to the corresponding side, corresponding to the corresponding end of the shaft hardware. The shaft hardware in the released state can tilt to the side without support force due to uneven force on both ends, and fall to the corresponding unloading port 42 through the discharge port 12, completing the sorting process of defective products.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
