Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 4 The present invention discloses an edge grinding device for automotive seals, comprising a support frame 1, a control panel 2 fixedly mounted on the bottom of the front side of the support frame 1, and a seal support mechanism 3, a seal positioning mechanism 4, and a grinding mechanism 5 sequentially mounted on the support frame 1. The seal support mechanism 3 consists of a servo motor 6, a rotating shaft 7, a support plate 8, four inner support plates 9, and four electric telescopic rods 10. The servo motor 6 is fixedly connected to the top of the back side of the support frame 1, the rotating shaft 7 is fixedly connected to the output shaft of the servo motor 6, the support plate 8 is fixedly connected to the end of the rotating shaft 7 away from the servo motor 6, the inner support plates 9 are slidably inserted through the arc-shaped outer side of the support plate 8, and the electric telescopic rods 10 are fixedly connected to the inside of the support plate 8 and fixedly connected to the inner support plates 9.

[0023] In use, the shaft seal skeleton is placed on the support plate 8, and the seal positioning mechanism 4 positions the shaft seal skeleton. The electric telescopic rod 10 drives the inner support plate 9 to move outward. The inner side of the shaft seal skeleton is supported by the four inner support plates 9. The inner support method allows the outer surface of the shaft seal to be fully exposed, thereby improving the convenience and comprehensiveness of grinding. Grinding can then be carried out by the grinding mechanism 5.

[0024] The sealing element positioning mechanism 4 consists of two cylinders 11 and a positioning ring 12. The cylinders 11 are inserted into the support frame 1 and fixedly connected to the support frame 1. The positioning ring 12 is fixedly connected to one end of the cylinders 11 and sleeved on the rotating shaft 7.

[0025] When the shaft seal frame is installed and positioned, cylinder 11 drives the positioning ring 12 to move to one side of the support plate 8 and forms a certain gap with the support plate 8. When the shaft seal frame is fitted onto the support plate 8, it can make the shaft seal frame and the support plate 8 centered and aligned, thus improving the accuracy of the shaft seal frame installation.

[0026] The grinding mechanism 5 consists of a second cylinder 13, a U-shaped support frame 14, a grinding motor 15, and a grinding wheel 16. The second cylinder 13 is fixedly connected to the support frame 1, the U-shaped support frame 14 is fixedly connected to the top of the second cylinder 13, the grinding motor 15 is fixedly connected to one side of the U-shaped support frame 14, and the grinding wheel 16 is rotatably connected to the inside of the U-shaped support frame 14 and fixedly connected to the output shaft of the grinding motor 15.

[0027] Cylinder 2 13 can drive the U-shaped support frame 14 to rise and fall, so as not to affect the installation and disassembly of the shaft seal frame. The grinding motor 15 drives the grinding wheel 16 to rotate, thereby enabling the grinding work.

[0028] The support plate 8 has an annular inner groove 17 inside, and the arc-shaped outer surface of the support plate 8 has a limiting groove 18 that communicates with the annular inner groove 17 and is slidably connected to the inner support plate 9, which can limit the inner support plate 9.

[0029] A cone 19 is fixedly provided at the end of the support plate 8 away from the rotating shaft 7, which can guide the shaft seal skeleton and improve the convenience of installing the shaft seal skeleton;

[0030] Two limiting rods 20 are fixedly installed at the bottom of the U-shaped support frame 14. The limiting rods 20 slide through the support frame 1, which can limit the U-shaped support frame 14.

[0031] The grinding wheel 16 consists of a central grinding roller 21, a first side grinding disc 22, and a second side grinding disc 23. The first side grinding disc 22 and the second side grinding disc 23 are fixedly connected to both ends of the central grinding roller 21, which can simultaneously grind the arc-shaped outer surface and both end faces of the shaft seal skeleton. The grinding surfaces of the central grinding roller 21, the first side grinding disc 22, and the second side grinding disc 23 can be set as flexible grinding structures, and the flexible grinding surfaces can be made of tungsten steel wire.

[0032] During operation, a sealing element support mechanism consisting of a servo motor, rotating shaft, support plate, four inner support plates, and four electric telescopic rods can support and fix the shaft seal skeleton, enabling rapid installation and positioning of the shaft seal skeleton. This mechanism also allows the shaft seal skeleton to rotate, improving the overall thoroughness of the grinding process. A sealing element positioning mechanism consisting of two cylinders and a positioning ring can position the shaft seal skeleton, preventing misalignment during installation. A grinding mechanism consisting of cylinder two, a U-shaped support frame, a grinding motor, and grinding wheels enables grinding operations on the shaft seal skeleton. A grinding wheel consisting of a central grinding roller, side grinding disc one, and side grinding disc two allows for simultaneous grinding of the curved outer surface and both end faces of the shaft seal skeleton, further enhancing the comprehensiveness of the grinding process.
