[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Refer to Figures 1-5As shown: A grinding wheel auxiliary replacement mechanism for a bridge housing grinding device includes a support platform 1. A guide rail 2 is fixedly connected to one side of the support platform 1. A replacement auxiliary component is provided above the guide rail 2. The replacement auxiliary component includes a limiting member 9, a drive shaft 15, and a support ring 18. An inner ring 22 is fixedly connected to the inner wall of the support ring 18. The drive shaft 15 is inserted through the inner ring 22. A guide groove is opened on the outer ring surface of the support ring 18. An extension rod 23 is engaged in the guide groove. The support ring 18 and the extension rod 23 are rotatably connected. A connecting frame 19 is fixedly connected to one side of the extension rod 23. The top of the connecting frame 19 is fixedly connected to one of the limiting members 9. A first insertion rod 16 and a second insertion rod 17 are fixedly connected to the inner wall of the other limiting member 9. The two limiting members 9 are connected by bolts. A positioning rod 21 and a guide rod 20 are respectively inserted into the first insertion rod 16 and the second insertion rod 17. A connecting shaft 10 is fixedly connected to one end of the positioning rod 21, and the other end of the positioning rod 21 is inserted into the support ring 18.

[0025] A grinding wheel body 4 is fixedly connected to the outer ring surface of the connecting shaft 10. An extension block 25 is fixedly connected to the outer ring surface of the connecting shaft 10. The extension block 25 is penetrated by a guide rod 20, and the guide rod 20 and the extension block 25 are slidably connected. One end of the guide rod 20 is fixedly connected to the support ring 18. One end of the connecting frame 19 is engaged with a second motor 24. The bottom of the second motor 24 is fixedly connected to the support platform 1. The drive shaft 15 is rotatably connected to the second motor 24.

[0026] The built-in ring 22 assists in the connection between the support ring 18 and the drive shaft 15. When the drive shaft 15 rotates, the support ring 18 rotates synchronously with the drive shaft 15. The extension rod 23 assists in the connection between the connecting frame 19 and the support ring 18. When the support ring 18 rotates, the connecting frame 19 supports the bottom of the support ring 18, ensuring the stable rotation of the support ring 18. The extension block 25 assists in the movement of the connecting shaft 10 along the guide rod 20. The guide rod 20 guides the installation of the connecting shaft 10. The positioning rod 21 limits the connection. The installation position of the connecting shaft 10 is determined by the insertion rod 16 and the insertion rod 27, which can limit the position of the guide rod 20 and the positioning rod 21, thereby reducing the looseness when the connecting shaft 10 is connected to the support ring 18. The two limiting parts 9 can be connected by bolts, thereby ensuring the stability of the insertion rod 16 and the insertion rod 27 during use. The motor 24 can support one side of the connecting frame 19 and provide power for the rotation of the drive shaft 15, thereby realizing the synchronous rotation of the connecting shaft 10, the grinding wheel body 4 and the drive shaft 15.

[0027] Example 2: Figures 1-3As shown, a placement plate 11 is attached to the bottom of the grinding wheel body 4. An electric push rod 14 is embedded inside the placement plate 11. One end of the electric push rod 14 is fixedly connected to a clamping plate 8. One side of the clamping plate 8 is attached to the grinding wheel body 4. A support frame 5 is fixedly connected to the bottom of the placement plate 11. A slide table 13 is slidably connected to one side of the support frame 5. An electric push rod 12 is embedded in the top of the slide table 13. The top of the electric push rod 12 is fixedly connected to the placement plate 11. A slide rod 7 is slidably connected to the slide table 13. Both ends of the slide rod 7 are fixedly connected to the guide rail 2. A lead screw 6 is threadedly connected to the slide table 13. One end of the lead screw 6 is rotatably connected to the guide rail 2. The other end of the lead screw 6 is fixedly connected to the output shaft of a motor 3. One side of the motor 3 is fixedly connected to the guide rail 2.

[0028] The placement plate 11 provides support for the bottom of the grinding wheel body 4. The distance between the clamping plate 8 and the grinding wheel body 4 can be adjusted by the extension and retraction of the electric push rod 14. Thus, the two symmetrical clamping plates 8 can clamp and fix the grinding wheel body 4, improving the stability of the grinding wheel body 4 when placed on top of the placement plate 11. The electric push rod 12 can adjust the height of the grinding wheel body 4 on top of the slide table 13, thereby adjusting the installation height of the grinding wheel body 4 and reducing the positional deviation of the grinding wheel body 4 during installation. The motor 3 provides power for the rotation of the lead screw 6, which in turn drives the slide table 13 to move, moving the grinding wheel body 4 toward the drive shaft 15. The slide rod 7 and the guide rail 2 can guide one end of the slide table 13, thereby improving the stability of the slide table 13 during movement.

[0029] The usage and working principle of this device are as follows: First, when installing the grinding wheel body 4, place it on top of the placement plate 11. Then, use the electric push rod 14 to drive the clamping plates 8 on both sides to move closer to the grinding wheel body 4, clamping and fixing the grinding wheel body 4. Then, use the electric push rod 12 to drive the placement plate 11 upward, changing the working height of the grinding wheel body 4 so that the axis of the connecting shaft 10 and the axis of the drive shaft 15 are on the same horizontal line. Then, use the motor 3 to drive the lead screw 6 to rotate. The lead screw 6 drives the slide table 13 to move along the slide rod 7 and the guide rail 2 through the thread, so that one end of the guide rod 20 is inserted into the outer ring of the connecting shaft 10. Within the extension block 25 on the surface, the slide 13 continues to move until the end of the positioning rod 21 is inserted into the support ring 18. At this point, the assembly of the connecting shaft 10 and the drive shaft 15 is completed. The inner wall of the limiting member 9 at the top is equipped with a first insertion rod 16 and a second insertion rod 17. The first insertion rod 16 and the second insertion rod 17 are inserted into the positioning rod 21 and the guide rod 20 respectively. Then, the bolts are rotated to connect the two limiting members 9, which can realize the installation and fixation of the grinding wheel body 4 and the connecting shaft 10. The placement plate 11 is moved down, the clamping plate 8 is separated from the grinding wheel body 4, and the drive shaft 15 and the grinding wheel body 4 are driven to rotate by the second motor 24, which can realize the grinding of the bridge housing.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
