[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 5As shown, the utility model provides a bidirectional spiral multifunctional polishing device for bearing processing, including a fixed plate 1, a bidirectional polishing mechanism 3 is arranged on the top of the fixed plate 1, a fixing mechanism 4 is arranged on the top of the bidirectional polishing mechanism 3, the bidirectional polishing mechanism 3 includes a placement tank 301, a first motor 302, two U-shaped plates 304 and a U-shaped frame 310, the first motor 302 is installed at the bottom of the fixed plate 1, the output end of the first motor 302 slides through the bottom of the fixed plate 1 and extends to the top, the output end of the first motor 302 is fixedly connected to the first spiral polishing rod 303, the tops of the two U-shaped plates 304 are each provided with a second motor 305, the output ends of the two second motors 305 both slide through the tops of the U-shaped plates 304 and Extending downward, the output ends of the two second motors 305 are fixedly connected to the rotating rod 306, the bottoms of the two U-shaped plates 304 are fixedly connected to the top of the fixed plate 1, the outer surfaces of the two rotating rods 306 are provided with first gear sleeves 307, the outer surfaces of the two first gear sleeves 307 are meshingly connected with the second gear sleeves 308, the inner surfaces of the two second gear sleeves 308 are provided with second spiral polishing rods 309, the bottom of the placement tank 301 is fixedly installed on the top of the fixed plate 1, the inner surface wall of the U-shaped frame 310 is provided with two telescopic rods 311, the telescopic ends of the two telescopic rods 311 slide through the fixed plate 1 and the bottom of the placement tank 301 and extend to the top, and the top of the U-shaped frame 310 is fixedly connected to the bottom of the fixed plate 1.

[0024] The effect achieved by the entire embodiment 1 is that when using the device to polish a bearing, first, the bearing is placed inside the placement tank 301, and then the first motor 302 is started, and the output end of the first spiral polishing rod 303 is used to drive the first spiral polishing rod 303 to rotate. As the first spiral polishing rod 303 rotates, the polishing medium on its surface will contact the inner surface wall of the bearing, thereby achieving polishing of the inner surface wall of the bearing. At the same time, the second motor 305 on the U-shaped plate 304 is started, and the output end of the second motor 305 is used to drive the rotating rod 306 to rotate. During the rotation of the rotating rod 306, the first gear sleeve 307 can be driven to rotate synchronously. Since there is a gear transmission relationship between the first gear sleeve 307 and the second gear sleeve 308, the rotation of the first gear sleeve 307 will drive the second gear sleeve 308 to rotate in conjunction, and since the first gear sleeve 307 is driven to rotate synchronously with the second gear sleeve 308, the rotation of the first gear sleeve 307 will drive the second gear sleeve 308 to rotate in conjunction with the first gear sleeve 308. The diameter of the first gear sleeve 307 is smaller than that of the second gear sleeve 308, so it can have a deceleration effect on the second gear sleeve 308. During the rotation of the second gear sleeve 308, it will drive the second spiral polishing rod 309 to rotate synchronously. As the second spiral polishing rod 309 rotates, its polishing medium will contact the outer surface of the bearing, thereby realizing the polishing treatment of the outer surface of the bearing. After the bearing is polished, the two telescopic rods 311 on the U-shaped frame 310 are started, and the bearing is driven to move upward with its telescopic end, thereby facilitating the staff to remove it. Under the action of the two-way polishing mechanism 3, the inner and outer surfaces of the bearing can be polished synchronously, avoiding disassembly or other methods of separate treatment of the inner surface after polishing the outer surface, which not only improves work efficiency but also reduces the complexity of operation.

[0025] Embodiment 2, as Figure 1-Figure 5 As shown, the fixing mechanism 4 includes a mounting cover 401, the top of the mounting cover 401 is fixedly connected to a handle 402, the bottom of the mounting cover 401 near the four corners is fixedly connected to a fixing rod 403, the bottom of the mounting cover 401 is movably mounted on the top of the placement tank 301, and the bottom of the fixing plate 1 near the four corners is fixedly connected to a support column 2.

[0026] The effect achieved by the entire embodiment 2 is that, when in use, the staff holds the handle 402 to cover the installation cover 401 on the top of the placement tank 301. After the installation cover 401 completely covers the top of the placement tank 301, the fixing rod 403 will naturally droop and come into conflict with the bearing surface being polished. Under the action of the fixing mechanism 4, the position of the bearing during the polishing process can be fixed to prevent it from moving or shaking, ensuring that the bearing is subjected to uniform polishing force during the polishing process, thereby improving the polishing quality. The support column 2 is mainly used to stabilize the fixing plate 1 and the entire device.

[0027] Working principle: When in use, the bearing is placed inside the placement tank 301, and the first motor 302 is started to drive the first spiral polishing rod 303 to rotate to polish the inner surface wall of the bearing. At the same time, the second motor 305 is started to drive the rotating rod 306 to rotate. During the rotation of the rotating rod 306, the first gear sleeve 307 can be driven to rotate synchronously. Through the gear transmission of the first gear sleeve 307 and the second gear sleeve 308, the rotation of the first gear sleeve 307 will drive the second gear sleeve 308 to rotate in conjunction. During the rotation of the second gear sleeve 308, it will drive the second gear sleeve 308 to rotate. The spiral polishing rod 309 rotates synchronously. As the second spiral polishing rod 309 rotates, its polishing medium will contact the outer surface of the bearing to polish the outer surface of the bearing. After the bearing is polished, the two telescopic rods 311 on the U-shaped frame 310 are started to drive the bearing to move upward, thereby facilitating the staff to take it out. Then the staff takes the handle 402 and covers the installation cover 401 on the top of the placement tank 301. After the installation cover 401 completely covers the top of the placement tank 301, the fixing rod 403 will naturally droop and conflict with the bearing surface being polished.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
