[0002] A floating oil seal is a sealing device used to prevent liquid or gas leakage. Floating oil seals are commonly used to seal rotating shafts. For example, in mechanical equipment, automobile engines, and hydraulic systems, when the shaft rotates, the floating ring rotates with it and maintains close contact with the shaft, thereby preventing liquid or gas from leaking into the surrounding environment of the shaft. The advantages of floating oil seals include good sealing performance, long service life, and easy installation. At the same time, since floating oil seals are usually seals between metals, they also have high wear resistance and corrosion resistance. After production, the floating oil seal needs to be polished, and a polishing device is required.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0019] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in, Figure 1 This is a structural schematic diagram of the top of the device seat of the surface polishing device for floating oil seal production provided by the utility model; Figure 2 for Figure 1 The overall external structural diagram of the surface polishing device for floating oil seal production shown in FIG. Figure 3 for Figure 1 A partial enlarged schematic diagram of the area at point A in the middle. The surface polishing device for floating oil seal production includes: a base 1, a circular device seat 2 is vertically fixedly connected to the upper surface of the base 1;

[0020] There are multiple transverse grooves 3, and the transverse grooves 3 are all opened on the upper surface of the device seat 2 along the radial direction of the device seat 2. The interiors of the multiple transverse grooves 3 are all horizontally rotatably connected with threaded rods 4. The outer surfaces of the multiple threaded rods 4 are respectively threadedly connected with threaded sleeves 5 that are respectively slidably connected to the interiors of the multiple transverse grooves 3. The tops of the multiple threaded sleeves 5 are vertically fixedly connected with positioning columns 6. The outer ends of the multiple threaded rods 4 can rotatably pass through the outer surface of the device seat 2 and extend outward. The outer surfaces of the multiple threaded rods 4 and the outer surface of the device seat 2 are all fixedly connected with the first bevel gear 8. The outer surface of the device seat 2 and the second bevel gear 9 located between each two adjacent first bevel gears 8 are horizontally rotatably connected. Each second bevel gear 9 is meshed with its two adjacent first bevel gears 8.

[0021] The outer surface of the device base 2 is fixedly connected to a mounting bracket 10 , the outer surface of the mounting bracket 10 is fixedly connected to a first motor 11 , and the output shaft of the first motor 11 is fixedly connected to the outer surface of a first bevel gear 8 .

[0022] When the device is in use, the oil seal is fixed by multiple locking columns 6. In actual use, the oil seal is placed on the upper surface of the device seat 2, and then the device is started. The multiple threaded rods 4 will rotate synchronously, thereby driving the multiple threaded sleeves 5 to move synchronously. During the movement of the multiple threaded sleeves 5, the multiple locking columns 6 will move closer to each other or disperse. During the dispersion process, when the multiple locking columns 6 are tightly fitted to the inner ring surface of the oil seal, the oil seal can be fixed. In addition, this structure can adapt to oil seals of various specifications, which improves the practicality of the device.

[0023] When the first motor 11 is running, the rotation of its output shaft will drive a first bevel gear 8 to rotate, and the first bevel gear 8 will drive the second bevel gear 9 meshing with it to rotate, and the second bevel gear 9 will drive another first bevel gear 8 meshing with it to rotate, so that multiple first bevel gears 8 can rotate synchronously by reciprocating, thereby enabling multiple threaded rods 4 to rotate synchronously.

[0024] The outer surfaces of the plurality of positioning posts 6 are all fixedly connected with anti-sliding blocks 7 .

[0025] The anti-sliding block 7 can play an anti-slip effect and improve the stability of the device when fixing the oil seal.

[0026] A plurality of support rods 12 are vertically fixedly connected to the upper surface of the base 1 , and a top plate 13 is laterally fixedly connected to the top ends of the plurality of support rods 12 .

[0027] The lower surface of the top plate 13 is vertically fixedly connected to a plurality of electrically controlled telescopic rods 14 , the bottom ends of the electrically controlled telescopic rods 14 are laterally fixedly connected to movable blocks, and the bottom ends of the movable blocks are vertically rotatably connected to a polishing disc 16 .

[0028] After the oil seal is fixed by multiple locking columns 6, multiple electrically controlled telescopic rods 14 can be started to extend, thereby driving the polishing plate 16 to descend until the polishing plate 16 contacts the oil seal. Then, as the polishing plate 16 rotates, the oil seal can be polished.

[0029] The top of the movable block is fixedly connected to a second motor 15 . The output shaft of the second motor 15 rotatably passes through the movable block and is fixedly connected to the upper surface of the polishing plate 16 .

[0030] When the second motor 15 is running, the output shaft thereof rotates to drive the polishing disc 16 to rotate, and the second motor 15 serves as the power structure of the polishing disc 16 .

[0031] The working principle of the surface polishing device for floating oil seal production provided by the utility model is as follows:

[0032] When the first motor 11 is running, the rotation of its output shaft will drive a first bevel gear 8 to rotate, and the first bevel gear 8 will drive the second bevel gear 9 meshing with it to rotate, and the second bevel gear 9 will drive another first bevel gear 8 meshing with it to rotate. This reciprocating motion can make multiple first bevel gears 8 rotate synchronously, so that multiple threaded rods 4 can rotate synchronously, thereby driving multiple threaded sleeves 5 to move synchronously. During the movement of multiple threaded sleeves 5, multiple positioning columns 6 will move closer to each other or disperse from each other. During the dispersion process, when multiple positioning columns 6 are tightly fitted to the inner annular surface of the oil seal, the oil seal can be fixed. After the oil seal is fixed by multiple positioning columns 6, the multiple electrically controlled telescopic rods 14 can be started to extend, thereby driving the polishing disc 16 to descend until the polishing disc 16 contacts the oil seal, and then the oil seal can be polished as the polishing disc 16 rotates.

[0033] Compared with the related art, the surface polishing device for floating oil seal production provided by the utility model has the following beneficial effects:

[0034] The present utility model provides a surface polishing device for producing floating oil seals. By arranging a plurality of retaining columns 6, the device fixes the oil seal by the plurality of retaining columns 6 when in use. In actual use, the oil seal is placed on the upper surface of the device seat 2, and then the device is started. The plurality of threaded rods 4 will rotate synchronously, thereby driving the plurality of threaded sleeves 5 to move synchronously. During the movement of the plurality of threaded sleeves 5, the plurality of retaining columns 6 will move closer to each other or disperse from each other. During the dispersion process, when the plurality of retaining columns 6 are tightly fitted to the inner annular surface of the oil seal, the oil seal can be fixed. In addition, the structure can adapt to oil seals of various specifications, thereby improving the practicality of the device.
