For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 As shown, a device 3 for disassembling and assembling a locking nut comprises a first arc plate 31, a second arc plate 32 and a fixing member 33; the structure of the first arc plate 31 is the same as that of the second arc plate 32, which are centrally symmetrically arranged, and the two ends are connected by fixing members 33 respectively.

[0030] like Figure 2 and 3 As shown, the first arc plate 31 includes a first arc segment 311 and a second arc segment 312 connected to the first arc segment 311, the radius of the first arc segment 311 is the same as the radius of the second arc segment 312; a first boss 313 is provided on the outer diameter of the first arc segment 311; correspondingly, the second arc plate 32 includes a third arc segment 321 and a fourth arc segment 322 connected to the third arc segment 321, the radius of the third arc segment 321 is the same as the radius of the fourth arc segment 322; a second boss 323 is provided on the outer diameter of the fourth arc segment 322.

[0031] like Figure 4 As shown, the outer diameter of the commonly used locking nut 1 is generally in the range of 100mm to 630mm. The prior art equips the locking nut 1 with a special wrench 2 for each size. With the device 3 for disassembling and assembling the locking nut of the utility model, only four sets of the device 3 for disassembling and assembling the locking nut are needed to meet the needs of ship repair, namely, one set of 100mm to 240mm; one set of 250mm to 370mm; one set of 380mm to 500mm; and one set of 510mm to 630mm. By striking the plane formed by the first boss 313 or the second boss 323, the locking nut 1 impacts an increased force-bearing surface, and the force is evenly applied, thus avoiding the technical problem of the locking nut 1 being deformed and damaged by impact.

[0032] In this embodiment, the cross-section of the first boss 313 and the cross-section of the second boss 323 are triangular, and the force is more uniform when knocked. Install according to the disassembly direction, that is, the spiral rotation is reversed. After installation, the plane vertical center of the first boss 313 or the second boss 323 is close to tangent to the disassembled locking nut 1, preferably, the cross-section is an isosceles right triangle, and the force is more dispersed when knocked, thereby reducing local force and improving disassembly efficiency.

[0033] In this embodiment, the inner diameter of the connection between the first arc segment 311 and the first arc segment 311 is provided with a third boss 314, and correspondingly, the inner diameter of the connection between the third arc segment 321 and the fourth arc segment 322 is provided with a fourth boss 324. Specifically, the shapes of the third boss 314 and the fourth boss 324 match the shape of the keyway of the locking nut 1. The third boss 314 or the fourth boss 324 is used to engage the keyway of the locking nut 1 to increase the stability of the installation.

[0034] In this embodiment, the first arc segment 311 , the second arc segment 312 , the first boss 313 and the third boss 314 are integrally formed, and the third arc segment 321 , the fourth arc segment 322 , the third boss 314 and the fourth boss 324 are integrally formed.

[0035] In this embodiment, if Figure 1 As shown, the first connecting section 315 and the second connecting section 316 are respectively extended from both ends of the first arc plate 31, and correspondingly, the third connecting section 325 and the fourth connecting section 326 are respectively extended from both ends of the second arc plate 32, the first connecting section 315 is connected to the fourth connecting section 326, and the second connecting section 316 is connected to the third connecting section 325. Specifically, the length of the first arc section 311 is the same as the length of the second arc section 312; the length of the first connecting section 315, the length of the second connecting section 316, the length of the third connecting section 325 and the length of the fourth connecting section 326 are the same, and the first connecting section 315 and the fourth connecting section 326, the second connecting section 316 and the third connecting section 325 are respectively connected by through-connection bolts 331.

[0036] In this embodiment, the length of the first arc segment 311 is different from the length of the second arc segment 312; the length of the first connecting segment 315 is the same as the length of the fourth connecting segment 326, which are connected by a through-connecting bolt 331; the length of the second connecting segment 316 is the same as the length of the third connecting segment 325, which are hinged by a pin 332. Figure 5 As shown, the second connecting section 316 and the fourth connecting section 326 may be omitted so that the first arc-shaped plate 31 and the second arc-shaped plate 32 are directly hinged.

[0037] like Figure 6 and 7 As shown, taking the universal tooling of 250mm to 370mm as an example, the smallest locking nut 1 has an outer diameter of 250mm, a keyway width of 20mm and a depth of 10mm; the largest locking nut 1 has an outer diameter of 370mm, a keyway width of 24mm and a depth of 17.5mm.

[0038] Considering that the minimum locking nut 1 keyway is 20mm wide and 10mm deep, the locking protrusions are determined to be 19mm and 9mm; considering that the largest locking nut 1 has an outer diameter of 370mm, the inner arc of the tooling is determined to be R185mm; considering that the largest locking nut 1 for disassembly and assembly has an outer diameter of 370mm, the distance between the two symmetrical arc-shaped clamps is determined to be 170mm.

[0039] When disassembling and assembling the locking nut 1 of 250mm to 370mm, the third boss 314 and the fourth boss 324 of the first arc plate 31 and the second arc plate 32 are symmetrically inserted into the keyway of the locking nut 1, and two bolts suitable for the length are selected, installed on both sides of the tooling and tightened; a hammer 4 is used to hit the plane to tighten or loosen the locking nut 1.

[0040] The utility model discloses a device for disassembling and assembling a locking nut, which has a wide application range. Four sets can basically meet the use of locking nuts such as ships. The clamping is firm, safe and reliable, and can be operated by one person. The contact surface between the device for disassembling and assembling the locking nut and the locking nut is large, the impact force surface is increased, the force is evenly applied, and the locking nut will not be damaged by the impact. The stress transmission effect is better when combined with a larger hammer impact force.
