Description

Technical Field

[0001] The present application relates to the technical field of mechanical equipment maintenance and repair, and in particular to a tool for efficiently removing special-shaped nuts. Background Art

[0002] Special-shaped nuts are parts that tightly connect mechanical equipment. Special-shaped nuts and bolts of the same specifications can be connected together through the inner thread. Special-shaped nuts are screwed together with bolts or screws to act as fastening parts. They are a component that must be used in all manufacturing machinery. According to different materials, they are divided into several major types, such as carbon steel, stainless steel, and non-ferrous metals (such as copper).

[0003] At present, special-shaped nuts are disassembled by anchor claws, but the tool anchor claws have no limiting and straightening functions during the disassembly process, resulting in uneven force on the nut during the disassembly process, which is easy to cause slipping and inconvenience in use.

The convex claw is close to the groove, and the external limiting ring is put on the outer periphery of the special-shaped nut body to prevent slipping caused by uneven force or angle deviation. When the convex claw is retracted to a predetermined distance, the pressurized air bag on its top will be compressed, so the internal medium enters the expansion air bag through the conveying cavity.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0023] Embodiment 1:

[0024] This application discloses a tool for efficiently removing special-shaped nuts. Figure 1-5 , including a special-shaped nut body 1, a plurality of grooves provided on one side of the special-shaped nut body 1, and a disassembly tube 2 for disassembling the special-shaped nut body 1, a disassembly component is provided at one end of the disassembly tube 2 facing the groove; the disassembly component includes a limit ring 3 and a plurality of protruding claws 4, the limit ring 3 is integrally arranged with the disassembly tube 2, and the limit ring 3 can be sleeved on the outside of the special-shaped nut body 1, a plurality of limit blocks 5 are movably installed on the inner wall of the limit ring 3, and a plurality of protruding claws 4 match the grooves, a sliding groove for accommodating the sliding of the protruding claws 4 is provided on the disassembly tube 2, a plurality of limit grooves 6 are provided on the outside of the part of the protruding claws 4 located in the disassembly tube 2, and a limit rod 7 abutting against the limit groove 6 is installed inside the disassembly tube 2, a pressure component is installed on the top of the protruding claws 4, and the pressure component is used to drive the limit block 5 to move. The disassembly tube 2 is put on the special-shaped nut body 1, and it is rotated to automatically find the groove of the special-shaped nut body 1 and limit it. The cam 4 is close to the groove, and the external limiting ring 3 is put on the periphery of the special-shaped nut body 1 to prevent slipping caused by uneven force or angle deviation. When the cam 4 shrinks to a predetermined distance, the pressurized air bag 10 on its top will be compressed, so the internal medium enters the expansion air bag 8 through the conveying cavity. The expansion air bag 8 deforms and expands, thereby pushing multiple limiting blocks 5 to resist the outside of the special-shaped nut body 1. Under the joint action of multiple limiting blocks 5, not only the concentricity of the disassembly tube 2 and the special-shaped nut body 1 can be improved, but also the fitting firmness of the limiting ring and the special-shaped nut body 1 can be further improved.

[0025] An expansion airbag 8 is fixed between the limit block 5 and the limit ring 3, and a rubber wear-resistant layer is fixed on the side of the limit block 5 facing the special-shaped nut body 1. The limit rod 7 is rotatably installed on the inner wall of the disassembly tube 2, and a spring is also fixed between the limit rod 7 and the inner wall of the disassembly tube 2. A compression spring 9 is provided on the side of the cam 4 away from the limit rod 7, and the two ends of the compression spring 9 are respectively abutted against the cam 4 and the inner wall of the disassembly tube 2. The pressurized component includes a pressurized airbag 10 and a conveying cavity. The pressurized airbag 10 is fixed to the top of the cam 4, and the inner wall of the pressurized airbag 10 is filled with a medium. The pressurized airbag 10 is connected with the expansion airbag 8 through the conveying cavity. The length of the cam 4 is greater than the depth of the groove, and the cam 4 is made of steel.

[0026] When in use, the disassembly tube 2 only needs to be put on the special-shaped nut body 1, and the groove of the special-shaped nut body 1 is automatically found and limited by rotation. The protruding claws 4 are close to the groove, and the external limiting ring 3 is put on the periphery of the special-shaped nut body 1 to prevent slipping caused by uneven force or angle deviation, thereby extending the service life of the tool and the nut and reducing the risk of personal injury.

[0027] In addition, through the movable cam 4, it will be contracted by the groove during use. When the cam 4 contracts to a predetermined distance, the pressurized airbag 10 on its top will be compressed, so the internal medium enters the expansion airbag 8 through the conveying cavity. The expansion airbag 8 deforms and expands, thereby pushing multiple limit blocks 5 to resist the outer side of the special-shaped nut body 1. Under the joint action of multiple limit blocks 5, not only the concentricity of the disassembly tube 2 and the special-shaped nut body 1 can be improved, but also the fit firmness of the limit ring and the special-shaped nut body 1 can be further improved, so that there is no gap between them and the straightening effect is better. It should be noted that the medium can be oil or an aqueous solution, which can provide a strong thrust for the limit block 5.

[0028] At the same time, during the movement of the cam 4, the limiting rod 7 will abut against the limiting groove 6, thereby fixing the cam 4 and preventing the cam 4 from generating thrust on the special-shaped nut body 1 under the action of the compression spring 9, thereby effectively ensuring the stability of the disassembly tube 2 and the special-shaped nut body 1 when in use.

[0029] Embodiment 2:

[0030] Compared with the embodiment 1, the embodiment 2 of the present application adds a trigger ring 11, through which the protruding claw 4 can be restored for repeated use. Figure 3-5 A rubber wear-resistant layer is fixed on the side of the limit block 5 facing the special-shaped nut body 1, a trigger ring 11 is sleeved on the outside of the disassembly tube 2, and the trigger ring 11 is slidably connected to the disassembly tube 2, a trigger block 12 for squeezing the trigger ring 11 is fixed on the inner wall of the trigger ring 11, and a tension spring 13 fixed to the inner wall of the disassembly tube 2 is provided on the top of the trigger block 12.

[0031] Among them, when it is necessary to disassemble the special-shaped nut body 1 from the tube 2, the staff can push the trigger ring 11 downward, and the trigger ring 11 pushes the limit rod 7 through the trigger block 12 to rotate the limit rod 7, so that the limit rod 7 will be separated from the limit groove 6. At this time, the cam 4 will recover under the pulling force of the compression spring 9, and squeeze the special-shaped nut body 1 out of the limit ring 3. The staff does not need to manually disassemble the special-shaped nut body 1, which saves time and effort.

[0032] The disassembly tube 2 is put on the special-shaped nut body 1, and it is rotated to automatically find the groove of the special-shaped nut body 1 and limit it. The cam 4 is close to the groove, and the external limiting ring 3 is put on the periphery of the special-shaped nut body 1 to prevent slipping caused by uneven force or angle deviation. When the cam 4 shrinks to a predetermined distance, the pressurized air bag 10 on its top will be compressed, so the internal medium enters the expansion air bag 8 through the conveying cavity. The expansion air bag 8 deforms and expands, thereby pushing multiple limiting blocks 5 to resist the outside of the special-shaped nut body 1. Under the joint action of multiple limiting blocks 5, not only the concentricity of the disassembly tube 2 and the special-shaped nut body 1 can be improved, but also the fitting firmness of the limiting ring and the special-shaped nut body 1 can be further improved.

[0033] The above are only preferred specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and improved ideas of the present application, which should be covered by the protection scope of the present application.
