DETAILED DESCRIPTION

After several rubber rings to be detected are fixed in the center position by the self-centering control unit, whether the rubber rings have crack defects can be detected by operating the detector 25, the detector 25 is installed in the loading seat 24 by the clamping device, different types and functions and models of the detector 25 can be used according to different detection requirements and conditions by operating the clamping device, the detection effect is improved and the limitation of the device in use is reduced, the loading seat 24 on the first T seat 23 connected to the output end of the electric telescopic column 22 can be controlled to move up and down by controlling the electric telescopic column 22, the detector 25 is driven to detect whether the rubber rings have crack defects at different heights, dead angles in the detection process are avoided, rubber rings of different sizes and diameters can also be detected, the detection effect of the device on rubber products is further improved, the power source of the power slide block 21 can also be started, the power slide block 21 is limited to move on the slide rail, the loading seat 24 is driven to translate to different positions to detect rubber rings at different positions, the detector 25 can detect other rubber rings fixed in the same batch, different numbers of rubber rings can be detected by the device at the same time, the detection efficiency of the device is improved. When the device is in use, the rotating motor 28 can also be started to drive the rotating gear 29 to rotate, and the rotating gear ring 27 is meshed to rotate, so that the circular base 3 in the annular rotating groove 2 is limited to rotate, and the retaining circular block 4 on the circular base 3 is rotated. Since the rubber ring is equivalent to being installed on the retaining circular block 4, that is, when the retaining circular block 4 rotates, the rubber ring can be rotated, so that the rubber ring can be adjusted to the output end of the detector 25 at different side wall positions, so that the rubber ring can be detected at different positions, further avoiding the existence of dead angles in the detection process, reducing the limitations of the device in use while improving the detection effect and accuracy of the device. At the same time, when the circular base 3 rotates, the auxiliary gear 32 on it moves along the inner diameter of the retaining gear ring 30, so that the auxiliary gear 32 rotates while the circular base 3 rotates, so that the auxiliary gear 32 drives the driving gear 35 to rotate under the action of the first bevel gear 33 and the second bevel gear 36. At this time, the rubber pad is already in the detection state, indicating that the guide gear 47 has moved to the driving gear 35 and the two are in meshing state. At this time, the rotation of the driving gear 35 can drive the guide gear 47 to rotate, so that the circular support rod 41 on it rotates, and the pulley 45 rotates, so that the plurality of pulleys 45 rotate synchronously under the action of the tension belt 46, so that the plurality of circular support rods 41 rotate, and the rubber ring is supported by the plurality of circular support rods 41, and the rubber ring contacts the rubber cylinder 44 on the circular support rod 41. The friction force of the rubber ring in the supporting state is sufficient to drive the rubber ring to rotate, so that the different side wall positions on the rubber ring rotate to the working range of the detector 25, respectively, further reducing the existence of detection dead angles and improving the precision of the device for detecting the crack defect of the rubber ring. It is worth mentioning that when the rotating gear 29 meshes with the rotating gear ring 27 to rotate, the pinion drives the gear, so that the rotating gear ring 27 rotates at low speed, and when the rotating gear ring 27 drives the circular base 3 to rotate, the auxiliary gear 32 on it meshes with the retaining gear ring 30, that is, the retaining gear ring 30 drives the pinion auxiliary gear 32 to rotate, so that the rotating speed is too fast. At the same time, under the action of the first bevel gear 33 and the second bevel gear 36, the rotating speed of the circular support rod 41 is accelerated differently, and the rubber ring rotates according to its center at a high speed, so that the rubber ring rotates while rotating according to the circular base 3, which is used for quickly detecting the side wall of the rubber ring while slowly rotating itself, so that the detector 25 detects the rubber ring while constantly adjusting its position, avoiding the existence of dead angles in the detection process to affect the detection accuracy. By adjusting the speed of the rubber ring, the detection process can avoid dead angles while ensuring detection efficiency, and the need for manual adjustment of the position of the rubber ring by the staff to face the detector 25 for detection is avoided, thereby further reducing the limitations of the device in use while improving the detection efficiency and reducing the working intensity of the staff.

[0020] The pressure cleaning device in this embodiment is mounted on the locking gear 5 and is used to clean dust and impurities adhering to the rubber ring. The pressure cleaning device includes a displacement gear 8 connected to the locking gear 5; a handle is installed on the side of the displacement gear 8 away from the locking gear 5; a displacement rack 9; two displacement racks 9 are symmetrical on both sides of the displacement gear 8 and are meshed together; a displacement base 10 is slidably connected to the displacement rack 9; the displacement base 10 is mounted on the fixed circular block 4; an extension square column 11; two extension square columns 11 are respectively mounted on the two displacement racks 9; cleaning brushes 12 are installed on the opposite sides of the two extension square columns 11, the sidewall of the rubber ring is located at the moving path of the cleaning brush 12, and the two sides of the rubber ring are located between the two cleaning brushes 12; a limiting groove 13 is provided on the opposite back of the two extension square columns 11; a displacement groove 14 is provided on the fixed circular block 4; a displacement column 15 is connected to... A displacement T-block 16 is slidably connected within the displacement groove 14, and a displacement slide column 15 is slidably connected to the side of the displacement T-block 16. A displacement spring 17 is sleeved on the displacement slide column 15. One end of the displacement spring 17 is fixedly connected to the displacement groove 14, and the other end is fixedly connected to the displacement T-block 16. A pressure cylinder 18 is slidably connected to the side of the displacement T-block 16 near the locking gear 5. The displacement T-block 16 and the pressure cylinder 18 are slidably engaged. A locking tooth block 19 is connected to the end of the pressure cylinder 18 near the locking gear 5. The locking gear 5 is located at the moving path of the locking tooth block 19. When the locking gear 5 is limited, it is in mesh with the locking tooth block 19. A pressure spring 20 is sleeved on the pressure cylinder 18. One end of the pressure spring 20 is fixedly connected to the locking tooth block 19, and the other end is fixedly connected to the displacement T-block 16. When the device detects the rubber ring, the displacement block 16 is pulled outward to limit the displacement at the displacement sliding groove 14 and the displacement sliding column 15, so that the displacement spring 17 is in a buffering state, and the displacement block 16 drives the locking tooth block 19 to move away from the locking gear 5 under the action of the pressure cylinder 18 and the pressure spring 20, so that the two are no longer engaged, thereby releasing the locking of the locking gear 5. At this time, by rotating the handle, the displacement gear 8 on it rotates on the locking gear 5, so that the two rotate synchronously, so that the displacement gear 8 meshes with the two displacement racks 9 on the displacement base 10 to limit the relative movement, thereby driving the two extension cylinders 11 to move relatively, that is, to move close to the inner wall and outer wall of the rubber ring respectively, so that the cleaning brushes 12 on the extension cylinders 11 contact the rubber ring, and the two cleaning brushes 12 contact the rubber ring synchronously, so that the bristles on the cleaning brushes 12 wrap around the side wall of the rubber ring. At this time, by the self-rotation of the rubber ring, the dust or impurities adhering to the rubber ring can be cleaned under the action of the bristles, thereby avoiding the influence of these impurities or dust on the detection effect of the device, so that the device can clean the impurities or residues adhering to the surface of the rubber ring when detecting whether the rubber ring has a crack defect, further avoiding the confusion between the crack and the impurities during detection to produce a false judgment, not only improving the detection accuracy of the device for rubber products, but also improving the detection effect of the device for rubber products, so that the limitation of the device in use is reduced. At the same time, after the two cleaning brushes 12 contact the rubber ring to clean the impurities adhering thereto, the cleaning brushes 12 do not need to continue to move, indicating that the displacement gear 8 does not need to rotate. At this time, by loosening the displacement block 16, the displacement spring 17 in the buffering state is reset, thereby driving the locking tooth block 19 to move close to and contact the locking gear 5, so as to limit the locking gear 5, so that the displacement gear 8 on it is also limited, so that the cleaning brushes 12 in contact with the rubber ring cannot move or dislocate due to non-human factors during use, improving the use effect of the cleaning brushes 12 and avoiding displacement during use to affect the cleaning of the rubber ring, improving the detection effect and accuracy of the device. At the same time, after the locking tooth block 19 contacts the locking gear 5, since the strength of the displacement spring 17 is greater than that of the pressure spring 20, the displacement block 16 is limited to move on the pressure cylinder 18 under the continuous resetting of the displacement spring 17, so that the pressure spring 20 is in a buffering state, avoiding the dislocation of the locking tooth block 19 during use to release the locking of the locking gear 5, improving the use effect of the device, so that the cleaning brushes 12 are limited to the current position to avoid insufficient contact strength with the rubber ring due to long-term use, thereby reducing the cleaning effect.
