[0002] Floating oil seal ring is an effective mechanical seal, which is widely used in various engineering machinery products. Its biggest role is to ensure the effective bonding of metal surfaces and ensure the stable and reliable operation of machinery in harsh working environments. At present, the production and manufacturing methods of floating oil seal rings are mostly to first turn out an annular blank through a lathe, and then use a grinder to grind the annular surface of the annular blank to make its annular surface and end face become flat, smooth and bright sealing surfaces, thereby greatly improving the sealing performance of floating oil seal ring products during use.

[0003] The floating oil seal ring needs to be ground during production. For example, a Chinese patent with publication number CN213380748U discloses a grinding device for a small end face of a floating oil seal. However, when processing the end face of the floating oil seal ring, both end faces of the floating oil seal need to be ground, and the clamping structure and the multi-directional clamping structure used to fix the floating oil seal ring result in that the floating oil seal ring needs to be disassembled and turned over after grinding one side, and then the grinding process is continued, which is troublesome. Therefore, a grinding device for a floating oil seal is designed to solve the above-mentioned problems. Utility Model Content

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application discloses a grinding device for a floating oil seal. Figure 1-3 A floating oil seal grinding device comprises a processing table 1, a hydraulic cylinder 2 is fixedly connected to the rear of the processing table 1, an output end of the hydraulic cylinder 2 is fixedly connected to a mounting frame 3, a front portion of the mounting frame 3 is fixedly connected to a fixed frame 4, the hydraulic cylinder 2 is arranged to drive the mounting frame 3 to rise, so that the fixed frame 4 on one side of the mounting frame 3 rises, so as to facilitate the position adjustment of the fixed frame 4 according to the demand, a double-headed servo motor 5 is fixedly connected to the middle part of the fixed frame 4, an output end of the double-headed servo motor 5 is fixedly connected to a threaded rod 6, one side of the threaded rod 6 is threadedly connected to a moving tube 7, a side of the moving tube 7 away from the threaded rod 6 is fixedly connected to a mounting plate 8, the moving tube 7 and the fixed frame 4 are slidably connected, so that when the threaded rod 6 drives the moving tube 7 to move, the moving tube 7 can maintain a stable movement, and the front portions of the mounting plates 8 that are close to each other are both rotatably connected to the mounting rod 9, a side of the mounting rod 9 away from the mounting plate 8 is fixedly connected to a clamping plate 10, and the clamping plate 10 is arranged to be in a shape adapted to the floating oil seal ring as shown in FIG. Figure 1 The shown arc shape;

[0022] When the floating oil seal ring needs to be clamped by the clamping plate 10, the double-headed servo motor 5 can be used to drive the threaded rod 6 to rotate, so that the threaded rod 6 drives the moving tube 7 to move, and drives the mounting plate 8 on one side to move, and the mounting plate 8 drives the clamping plate 10 to move and clamp the floating oil seal ring set at the upper end of the processing table 1, so as to fix the floating oil seal ring; the floating oil seal ring is clamped on both sides, and the clamping plate 10 is used to increase the contact area when clamping the floating oil seal ring, so as to improve the stability of the floating oil seal ring clamping, which is conducive to the stable grinding of the floating oil seal ring.

[0023] By adopting the above technical solution, after the upper end surface of the floating oil seal ring is ground, its lower end surface also needs to be ground, so the floating oil seal ring needs to be flipped over. Therefore, a rotating rod 11 is fixedly connected to the side of the mounting rod 9 away from the mounting plate 8, and a rotating plate 12 is fixedly connected to the side of the rotating rod 11 away from the mounting rod 9. The rotating plate 12 is plugged into the mounting plate 8 on the same side. The rotating plate 12 can be used to drive the rotating rod 11 to rotate, so that the rotating rod 11 drives the mounting rod 9 to rotate, and drives one side of the clamping plate 10 to rotate, so that the floating oil seal ring clamped on the clamping plate 10 is flipped over.

[0024] By adopting the above technical solution, after flipping, if the rotating plate 12 is not fixed, the clamping plate 10 will drive the floating oil seal ring to tilt, resulting in the grinding of the end surface. Therefore, the front and rear parts of the rotating plate 12 close to the same side mounting plate 8 are fixedly connected with the plug rod 16, and the plug rod 16 is plugged into the side wall of the mounting plate 8. When not in use, the plug rod 16 can be inserted into the mounting plate 8 to fix the rotating plate 12 on one side of the plug rod 16.

[0025] By adopting the above technical solution, in order to facilitate the restoration of the rotating plate 12 after use, a tension spring 15 is fixedly connected to the side of the rotating plate 12 close to the mounting plate 8, and the tension spring 15 is fixedly connected to the swivel ring 14 away from the rotating plate 12. The swivel ring 14 is rotatably connected to the mounting plate 8. After the rotating plate 12 is rotated to adjust the floating oil seal ring, the tension spring 15 can pull the rotating plate 12 to move, so that the rotating plate 12 drives the insertion rod 16 to be inserted into the mounting plate 8 again.

[0026] By adopting the above technical solution, the plug block 13 is fixedly connected to the side of the rotating plate 12 close to the rotating rod 11, and the plug block 13 is plugged into the rotating rod 11, so that the rotating plate 12 is not completely separated from the rotating rod 11 after being pulled, thereby being able to drive the rotating rod 11 to rotate.

[0027] By adopting the above technical solution, the rear upper end of the processing table 1 is fixedly connected to the fixed frame 17, and a grinding device 18 is installed on the fixed frame 17. The grinding device 18 is a common grinding device in the floating oil seal ring grinding process, which is generally composed of a grinding wheel, a motor and an electric telescopic rod. It is a commonly used technical means, so no further elaboration is made.

[0028] By adopting the above technical solution, an installation groove is opened in the middle of the processing table 1, and a filter screen 19 is fixedly connected to the installation groove. A collection frame is provided in the lower end of the filter screen 19, and the collection frame is fixedly installed at the bottom of the processing table 1. The filter screen 19 can allow the debris generated by grinding to pass through and enter the collection frame at the lower end for collection, thereby keeping the processing table 1 clean.

[0029] The implementation principle of a floating oil seal grinding device in an embodiment of the present application is as follows: a floating oil seal ring is placed on a processing table 1 and placed between two clamping plates 10, and then the double-headed servo motor 5 is started, so that the double-headed servo motor 5 drives the threaded rod 6 to rotate, and the threaded rod 6 drives the moving tube 7 to move, so that the moving tube 7 drives the mounting plate 8 on one side to move, and the mounting plate 8 drives the mounting rod 9, and the mounting rod 9 drives the clamping plate 10 to move, and the clamping plate 10 is brought close to the floating oil seal ring and clamps the side wall of the floating oil seal ring, and then the grinding device 18 is started, so that the grinding device 18 performs end face grinding on the floating oil seal ring. After grinding, the hydraulic cylinder 2 can be started to drive the mounting frame 3 to rise, and the mounting frame 3 drives the fixed frame 4 to rise, and the mounting plate 8 and the clamping plate 10 to rise, so that the floating oil seal ring clamped on one side of the clamping plate 10 rises, and then the rotating plate 12 on one side is pulled, so that the rotating plate 12 drives the plugging rod 16 to move, and separates the plugging rod 16 from the mounting plate 8, and at the same time drives the tension spring 15 to extend, and then rotates the rotating plate 12 180 degrees, so that the rotating rod 11 drives the mounting rod 9 to rotate, and the mounting rod 9 drives the clamping plate 10 to rotate, and drives the clamped floating oil seal ring to rotate 180 degrees, thereby completing the flipping of the floating oil seal, and then releases the rotating plate 12, so that the tension spring 15 drives the rotating plate 12 to recover, and the plugging rod 16 on one side can be plugged into the mounting plate 8 again, thereby completing the fixation after flipping, and starting the hydraulic cylinder 2, so that the hydraulic cylinder 2 drives the mounting frame 3 to descend, and the floating oil seal ring clamped on one side of the clamping plate 10 can be placed on the processing table 1 again.
