Description

Technical Field

[0001] The invention belongs to the field of bearing detection, and in particular relates to a machine tool spindle bearing defect detection device. Background Art

[0002] Machine tools are basic equipment in mechanical manufacturing, used to process metal or other materials to manufacture or repair parts. They use a combination of different mechanical movements and processing tools to perform operations such as cutting, forming, grinding, drilling, milling, turning, and polishing on workpieces to achieve the required shape, size, and surface quality. The machining accuracy of machine tools is related to the rotation accuracy of the spindle on them, and the rotation accuracy of the spindle is related to the bearings on them. Bearings can greatly reduce the resistance of the spindle during rotation and ensure the accuracy of rotation.

[0003] Since the bearing processing includes multiple processes such as forging, rolling, punching, turning, grinding, heat treatment, etc., various defects may appear on the surface of the inner and outer rings of the bearing. In order to ensure the accuracy of the bearing, the cracks and scratches on the surface of the inner and outer rings of the bearing must be detected after the bearing is produced.

[0004] In response to the above technical problems, the applicant has retrieved some existing technologies, such as the Chinese patent with patent publication number CN110346379B, which is a bearing defect detection device and a bearing defect detection method, including a frame, a transport component, a detection component, a drive component and a data processing module. The detection component is used to detect the bearing to be tested that is transported to the frame; the data processing module is used to collect machine vision images and detect the defect position of the bearing to be tested. It uses eddy current sensors and CCD cameras to perform flaw detection on bearings. Eddy current sensors can measure without contacting the bearing to be tested, with high measurement accuracy and low cost. In addition, the CCD camera combined with machine vision methods can ensure high-precision detection, replace human eye recognition, and reduce detection errors.

[0005] Since the mounting frame drives the CCD camera and eddy current sensor to rotate around the bearing to be tested, and thus performs a comprehensive inspection on the bearing to be tested, and since the inner diameter of the bearing to be tested is small, the CCD camera cannot fully and accurately inspect the bearing to be tested, resulting in a blind spot in the inspection, thereby affecting the inspection quality of the bearing.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In the present invention, by setting a cylindrical reflector and an LED lamp bead, when the inner ring of the bearing to be detected is detected, the cylindrical reflector is driven to rise to the top of the bearing to be detected by the second telescopic rod, and the power of the LED lamp bead is turned on.

[0026] 2. In the present invention, a turning mechanism is provided. After the bearing to be tested is placed on the turning mechanism, the turning mechanism can turn over the bearing to be tested, so that both sides of the bearing to be tested can be tested without manual assistance, thereby avoiding the bearing to be tested from being contaminated with other impurities and improving the quality of testing;

[0027] 3. In the present invention, by providing a driven gear ring, a second driving gear ring and a rotating tube, initially, the driven gear ring and the second driving gear ring are meshed, and the driving mechanism drives the second driving gear ring to rotate through the rotating tube, thereby driving the driven gear ring and the bearing to be detected to rotate, thereby performing a comprehensive inspection of the bearing to be detected and improving the inspection quality. After the turning mechanism turns over the bearing to be detected, another driven gear ring will also mesh with the second driving gear ring, so that the other side of the bearing to be detected can be fully inspected;

[0028] 4. In the present invention, by setting a double-ended screw, when testing bearings of different thicknesses, the double-ended screw drives two adjusting sliders to move toward or away from each other, so that the distance between the two driven gear rings can be adjusted to adapt to the thickness of the bearing to be tested, so as to avoid the bearing to be tested falling off the driven gear ring during rotation, so that the device can detect bearings of different thicknesses;

[0029] 5. In the present invention, by providing a correction mechanism, after placing the bearing to be tested, the correction mechanism is used to correct the bearing to be tested to make the axis of the bearing to be tested coincide with the axis of the driven gear ring, thereby avoiding the eccentric rotation of the bearing to be tested, which makes the image of the bearing to be tested captured by the CCD camera fluctuate, thereby affecting the test result, thereby improving the test quality;

[0030] 6. In the present invention, by providing an arc-shaped groove frame, an arc-shaped rack, a compression spring, a connecting pipe and a first driving gear ring, when the bearing to be tested is removed, the first telescopic rod drives the fixed plate to rise, so that the arc-shaped rack and the first driving gear ring are engaged, and the rotating tube can drive the arc-shaped rack and the driving cover to rotate through the connecting pipe and the first driving gear ring, so that the multiple material removal rods can move the bearing to be tested back to the correct position, without the need to set up an additional power device, thereby reducing the cost;

[0031] 7. In the present invention, after the material pusher pushes the bearing to be tested back to the correct position, the material pusher will be blocked by the inner wall of the bearing to be tested, but the rotating tube will continue to rotate. At this time, the first drive gear ring will squeeze the arc-shaped rack and retract the arc-shaped rack into the arc-shaped groove frame, so that the first drive gear ring passes over the arc-shaped rack and continues to rotate, preventing the material pusher from affecting the rotation of the rotating tube. Then, the first telescopic rod drives the material pusher to descend, disengaging the arc-shaped rack and the first drive gear ring, preventing the material pusher from continuously hitting the inner wall of the bearing to be tested.

[0054] By rotating the double-headed screw 89, the double-headed screw 89 drives the two adjustment sliders 87 to move toward or away from each other, so that the distance between the two driven gear rings 81 can be adjusted to adapt to the thickness of the bearing 6 to be tested, thereby preventing the bearing 6 to be tested from falling off the driven gear ring 81 during rotation.

[0055] like Figure 1 As shown, a machine tool spindle bearing defect detection device provided by the present invention, in this embodiment, the detection component 7 includes a mounting seat 74 fixedly connected to the detection platform 1, the top of the mounting seat 74 is hinged with a second mounting block 72, a first servo motor 73 is fixedly mounted on the mounting seat 74, the output shaft of the first servo motor 73 is fixedly connected to one end of the second mounting block 72, and a CCD camera 71 is fixedly mounted on the side of the second mounting block 72 close to the rotating tube 5, and the CCD camera 71 is used to capture the machine vision image of the bearing 6 to be detected.

The LED lamp bead 45 illuminates the inner wall of the bearing 6 to be inspected, making the inner wall of the bearing 6 to be inspected clearer, and the light irradiated on the inner wall of the bearing 6 to be inspected will be reflected on the cylindrical reflector 46. Due to the curvature of the outer surface of the cylindrical reflector 46, the light reflected by the inner wall of the bearing 6 to be inspected will not remain parallel after being reflected by the cylindrical reflector 46, but will be scattered in different directions. Therefore, the cylindrical reflector 46 can magnify the defects of the inner wall of the bearing 6 to be inspected, avoid the occurrence of detection blind spots, make the detection of the CCD camera 71 more accurate, and improve the detection quality.

At the same time, the top of the material removal rod 37 extends into the interior of the bearing 6 to be tested, so that the driving mechanism 9 drives the rotating tube 5 to rotate, the rotating tube 5 drives the connecting tube 312 and the first driving gear ring 313 to rotate, the first driving gear ring 313 drives the arc-shaped rack 310 to rotate, the arc-shaped rack 310 drives the driving cover 38 to rotate, the driving cover 38 drives the driving column 36 to move through the guide arc hole 311, the driving column 36 drives the material removal slider 34 and the material removal rod 37 to move, and the multiple material removal rods 37 move the bearing 6 to be tested back to the normal position;

[0068] After the material-moving rod 37 moves the bearing 6 to be detected back to the correct position, the material-moving rod 37 will be blocked by the inner wall of the bearing 6 to be detected. At this time, the material-moving rod 37 is fixed, but the rotating tube 5 will continue to rotate. At this time, the first driving gear ring 313 will squeeze the arc-shaped rack 310 and retract the arc-shaped rack 310 into the arc-shaped groove frame 39, so that the first driving gear ring 313 will continue to rotate over the arc-shaped rack 310, and prevent the material-moving rod 37 from affecting the rotation of the rotating tube 5. Then, the first telescopic rod 31 drives the material-moving rod 37 to descend, so that the arc-shaped rack 310 and the first driving gear ring 313 are disengaged, and prevent the material-moving rod 37 from continuously hitting the inner wall of the bearing 6 to be detected.

[0069] In order to improve the stability of the driving cover 38 when rotating, there are multiple arc-shaped groove frames 39 , and the multiple arc-shaped groove frames 39 are evenly distributed around the axis of the driving cover 38 .

[0070] Working principle: the bearing 6 to be detected is placed on the horizontal driven gear ring 81, and then the first telescopic rod 31 drives the fixed plate 33 to rise, and the fixed plate 33 drives the driving cover 38 and the arc-shaped rack 310 to rise, so that the arc-shaped rack 310 and the first driving gear ring 313 are meshed. At the same time, the top of the material-moving rod 37 extends into the interior of the bearing 6 to be detected, and the fourth servo motor 93 drives the second gear 92 and the first gear 91 to rotate, and the first gear 91 drives the rotating tube 5 to rotate, and the rotating tube 5 drives the first driving gear ring 313 and the arc-shaped rack 310 to rotate through the connecting tube 312, and the arc-shaped rack 310 drives the driving cover 38 to rotate, and the driving cover 38 drives the driving column 36 to move through the guide arc hole 311, and the driving column 36 drives the material-moving slider 34 and the material-moving rod 37 to move, and multiple material-moving rods 37 move the bearing 6 to be detected back to the correct position, and then the first telescopic rod 31 drives the driving cover 38 to descend, so that the arc-shaped rack 310 and the first driving gear ring 313 are disengaged;

[0071] The CCD camera 71 is started, and the CCD camera 71 takes a machine vision image of the bearing 6 to be inspected. The data processing module collects the machine vision image and detects the defect position on the bearing 6 to be inspected;

[0072] After the inspection of one side of the bearing 6 to be inspected is completed, the second servo motor 86 drives the rotating plate 85 on the vertical side to rotate 90°, and the rotating plate 85 drives the driven gear ring 81 through the arc frame 84 to clamp the bearing 6 to be inspected on the other driven gear ring 81, and then the third telescopic rod 88 drives the third servo motor 812 to rise, so that the third servo motor 812 drives the driven gear ring 81 to rise to a sufficient height, and then the third servo motor 812 drives the driven gear ring 81 to rotate 180° through the rotating block 811, and then the third telescopic rod 88 drives the third servo motor 812 to descend again, so that the driven gear ring 81 on the lower side is engaged with the second drive gear ring 10, and then the second servo motor 86 drives the driven gear ring 81 on the upper side to rotate 90°, so that the turning over of the bearing 6 to be inspected can be realized, and the CCD camera 71 can continue to inspect the other side of the bearing 6 to be inspected;

[0073] When the inner wall of the bearing 6 to be inspected is inspected, the cylindrical reflector 46 is driven to rise by the second telescopic rod 42, so that the top of the cylindrical reflector 46 is higher than the top of the bearing 6 to be inspected. At the same time, the first servo motor 73 drives the second mounting block 72 and the CCD camera 71 to rotate, so that the CCD camera 71 is facing the cylindrical reflector 46, and then the power of the LED lamp bead 45 is turned on. The LED lamp bead 45 illuminates the inner wall of the bearing 6 to be inspected, and the inner wall of the bearing 6 to be inspected will be reflected to the CCD camera 71 through the cylindrical reflector 46, and the cylindrical reflector 46 can magnify the defects of the inner wall of the bearing 6 to be inspected, so that the detection of the CCD camera 71 is more accurate.
