[0002] Oil retaining rings and sealing rings are indispensable parts when bearings are used in important parts of the product. They can play a good role in the lubrication and protection of bearings. Circular oil retaining rings may fall off. Changing the circular oil retaining ring to a hexagonal oil retaining ring can reduce the occurrence of falling off. However, the pressing tool for the circular oil retaining ring cannot be used when installing the hexagonal oil retaining ring. Therefore, a pressing tool needs to be designed for the hexagonal oil retaining ring. Utility Model Content

[0005] Furthermore, the inner pressure ring and the outer pressure ring are annular, threaded holes are provided on the inner pressure ring and the outer pressure ring, and the connecting rod is connected to the inner pressure ring and the outer pressure ring through threads.

[0006] Furthermore, the height of the inner pressure ring is lower than the depth of the groove on the positioning member.

[0007] Furthermore, the positioning pin is perpendicular to the bottom end surface of the positioning member.

[0008] Beneficial effects: Compared with the prior art, the hexagonal oil baffle ring pressing tool of the utility model can realize the rapid positioning of the hexagonal oil baffle ring. During the pressing, the hexagonal oil baffle ring is evenly stressed and will not damage the sealing ring and the oil baffle ring. The installation effect is good and the operation is convenient. Both machine pressing and hand pressing are possible. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] like Figure 1 and Figure 2 As shown, a hexagonal oil retaining ring pressing tool comprises a locating pin 1, a locating member 2, a connecting rod 3, a spring 4, an inner pressure ring 5 and an outer pressure ring 6. The locating member 2 is cylindrical and is provided with three mounting holes. The locating pin 1 is installed in the mounting hole. A groove is provided inside the locating member 2. The shape of the groove is consistent with that of the hexagonal oil retaining ring 7. The hexagonal oil retaining ring 7 can be placed in the groove. The inner pressure ring 5 is slidably installed in the groove to keep the lower end surface of the inner pressure ring 5 parallel to the lower end surface of the locating member 2. The inner pressure ring 5 is connected to the connecting rod 3. The locating member 2 is also provided with three through holes. The connecting rod 3 passes through the through holes to be connected to the outer pressure ring 6. The spring 4 is sleeved on the connecting rod 3. One end of the spring 4 abuts against the locating member 2, and the other end of the spring 4 abuts against the outer pressure ring 6.

[0015] The inner pressure ring 5 and the outer pressure ring 6 are annular, which is convenient for removing the pressing tool. The inner pressure ring 5 and the outer pressure ring 6 are provided with threaded holes. The connecting rod 3 is connected to the inner pressure ring 5 and the outer pressure ring 6 by threads to ensure that the inner pressure ring 5 is parallel to the outer pressure ring 6 and the force is uniform during pressing; the height of the inner pressure ring 5 is lower than the depth of the groove on the positioning member 2, which is convenient for placing the oil retaining ring; the positioning pin 1 is perpendicular to the bottom end face of the positioning member 2 to ensure accurate positioning during pressing.

[0016] like Figure 3 As shown, when using the press-fitting tool, first install the sealing ring 8 on the hexagonal oil retaining ring 7, apply the necessary grease for installation, and then place the hexagonal oil retaining ring 7 in the groove on the positioning piece 2 of the press-fitting tool so that the oil retaining ring abuts against the inner pressure ring 5, and then align the positioning pin 1 on the press-fitting tool with the bolt hole of the product 9 and install it on the product 9, then apply pressure to the outer pressure ring 6, and under the action of the connecting rod 3, drive the inner pressure ring 5 to press the hexagonal oil retaining ring 7 into the oil retaining ring installation position in the product 9. After press-fitting, Figure 4 As shown, just take out the pressing tool. The pressing tool can realize the rapid positioning of the oil retaining ring. During the pressing, the oil retaining ring is evenly stressed and will not be damaged. The operation is simple and convenient, the reliability is high, and the pressure can be applied manually or by machine, with strong versatility.

[0017] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
