[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] Example: A bearing disassembly tool, such as Figures 1-6 As shown, the fixture includes a bearing mounting base 1 and an auxiliary mechanism 2. The upper surface of the bearing mounting base 1 has a bearing hole 3, and the bearing body 4 is installed inside the bearing hole 3. The auxiliary mechanism 2 is located at the top of the bearing body 4. The auxiliary mechanism 2 includes a pressure block 201, a screw 202, a crossbeam 203, and a fixing arm 204. The auxiliary mechanism 2 simplifies the tooling structure, facilitates manufacturing and operation, and enables quick positioning of the bearing for disassembly.
[0026] like Figures 1-6 As shown, a pressure block 201 is provided at the top of the bearing body 4. The bottom end of the pressure block 201 is in uniform contact with the surface of the bearing body 4. The uniform contact allows the disassembly force to be applied evenly to the bearing, avoiding damage to the bearing due to uneven local force, improving the integrity of the bearing disassembly process, and extending the reusability of the bearing.
[0027] like Figures 1-3 As shown, a screw 202 is fixedly connected to the top of the pressure block 201. The pressure block 201 and the screw 202 are fixed by welding. The welding fixation ensures the stability and reliability of the connection between the two, can effectively transmit the force required for disassembly, reduce disassembly errors caused by loose connection, and improve stability.
[0028] like Figures 1-4 As shown, a crossbeam 203 is movably arranged above the screw 202. The screw 202 and the crossbeam 203 are connected by threads, and the crossbeam 203 can move vertically by sliding through the threads. The position of the pressure block 201 can be flexibly adjusted according to the installation height and disassembly requirements of different bearings, which improves the versatility and applicability of the tooling.
[0029] like Figures 1-5 As shown, fixed arms 204 are provided at both ends of the crossbeam 203. The bottom end of the fixed arm 204 has a specific shape. The fixed arm 204 can stably fix the tooling in the working position, thereby enhancing the stability and reliability of the tooling.
[0030] like Figures 1-5As shown, a copper block 5 is provided on the inner side of the bottom end of the fixed arm 204. The copper block 5 is fixed by screws. A rubber block 6 is provided on the protruding upper surface of the bottom end of the fixed arm 204. The rubber block 6 is fixed by riveting. The copper block 5 on the inner side can prevent the fixed arm 204 from directly contacting the equipment surface and causing scratches, thus protecting the equipment. The rubber block 6 can increase the friction between the fixed arm 204 and the equipment surface, making the tooling more secure. It can also act as a buffer during disassembly, reducing the impact on the equipment, further protecting the equipment and improving its service life.
[0031] Working principle: By placing the fixture in a suitable position, the bottom end of the fixed arm 204 contacts the equipment or mounting base where the bearing to be disassembled is located. Due to the specific shape of the bottom end of the fixed arm 204, it can adapt to different installation scenarios. Furthermore, the copper block 5 on the inner side of the bottom end of the fixed arm 204 protects the equipment surface from scratches, and the rubber block 6 protruding from the upper surface of the bottom end increases friction, ensuring the fixture is stably fixed in the working position. By rotating the crossbeam 203 above the screw 202, since the screw 202 and the crossbeam 203 are connected by threads, the crossbeam 203 will move vertically along the screw 202, adjusting the crossbeam 203 to... The appropriate position allows the pressure block 201 connected to the bottom of the screw 202 to contact the top of the bearing body 4. The crossbeam 203 continues to rotate. As the crossbeam 203 descends, the screw 202 will drive the pressure block 201 to move downward. Since the bottom of the pressure block 201 is in uniform contact with the surface of the bearing body 4, the pressure block 201 will apply a uniform pressure to the bearing body 4 during the downward movement, thereby gradually removing the bearing from the bearing hole 3 of the bearing mounting seat 1. When the bearing is completely pulled out of the bearing hole 3, the rotation of the crossbeam 203 is stopped, and then the tooling is removed from the equipment, thus completing the bearing disassembly work.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
