However, since the application of the disassembly tool is relatively single, it is not convenient to install the crankshaft oil seal. As a result, when installing the crankshaft oil seal, it is necessary to carry the installation tool for installation, which cannot achieve the dual-use effect, thereby reducing convenience.

[0005] In view of the above problems, the utility model document proposes a special type of high-efficiency tooling for oil seal disassembly. Utility Model Content

[0006] The utility model provides a special type of high-efficiency tool for disassembling oil seals, which solves the problem in the prior art that the application of the disassembly tool is relatively single and it is inconvenient to install the crankshaft oil seal, resulting in the need to carry installation tools when installing the crankshaft oil seal, and the dual-use effect cannot be achieved, thereby reducing the disadvantage of convenience.

[0007] The utility model provides the following technical solutions:

[0008] A special type of high-efficiency tooling for oil seal removal, comprising:

[0009] A connecting ring, wherein the top of the connecting ring is symmetrically fixed with fixing frames in pairs, one end of the four fixing frames is fixedly provided with a same threaded plate, the inner thread of the threaded plate is connected with a driving screw, and the top of the driving screw is fixedly provided with a turning handle;

[0010] An installation mechanism, the installation mechanism is arranged in the connecting ring and is used to install and fix the crankshaft oil seal;

[0011] The disassembly mechanism is arranged in the connecting ring and is used for quickly disassembling the crankshaft oil seal.

[0012] In one possible design, the mounting mechanism includes a drive plate, which is rotatably connected to the bottom end of the drive screw via a rotating shaft. A pressing ring that matches the crankshaft oil seal is fixedly mounted on the bottom side of the drive plate, and a plurality of grooves are formed on the bottom side of the pressing ring.

[0013] In a possible design, the disassembly mechanism includes two threaded holes, both of which are opened inside the drive plate, and the inside of the two threaded holes is threadedly connected with a threaded rod, the top end of the threaded rod is fixedly provided with a handle, and the bottom end of the threaded rod is fixedly provided with a pointed cone for penetrating the crankshaft oil seal.

[0014] In a possible design, two through holes are provided at the bottom of the pressing ring for accommodating the pointed cone, and both through holes are connected to the threaded hole.

[0015] In a possible design, telescopic rods are symmetrically fixedly arranged in pairs on the top of the driving plate, and the top end of each telescopic rod is fixed to the bottom side of the fixing frame.

[0016] In a possible design, two positioning rods are fixedly provided at the bottom of the connecting ring, and a plurality of connecting holes adapted to the engine connection are opened at the top of the connecting ring.

[0017] In the present application, the connecting ring is firstly fitted to the corresponding engine connection, and then the connecting screw is passed through the connecting hole on the connecting ring and fixed to the corresponding connection of the engine to ensure that the connecting ring is firmly installed on the engine, so as to facilitate the disassembly of the crankshaft oil seal in the later stage.

[0019] In the utility model, the special oil seal removal high-efficiency tooling can press the crankshaft oil seal into the inside of the corresponding connection ring groove through the installation mechanism, thereby achieving the effect of crankshaft oil seal installation, enhancing the firmness of crankshaft oil seal installation, and thus enhancing the application range of the device;

[0020] In the utility model, the special oil seal disassembly efficient tooling can easily disassemble the crankshaft oil seal from the engine through the disassembly mechanism, thereby achieving the effect of rapid disassembly, improving work efficiency and reducing operation difficulty;

[0021] In the utility model, the crankshaft oil seal is easy to install and disassemble, the firmness of the crankshaft oil seal installation is enhanced, and the application range of the device is further enhanced, avoiding the need to carry installation tools when installing the crankshaft oil seal, achieving a dual-use effect and improving convenience.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Example 1

[0030] Please refer to Figure 1-Figure 4 , a disassembly efficient tool, comprising:

[0031] A connecting ring 1, the top of which is symmetrically fixed with fixing frames 2, one end of the four fixing frames 2 is fixedly provided with the same threaded plate 3, the internal thread of the threaded plate 3 is connected with a driving screw 4, the top of the driving screw 4 is fixedly provided with a turning handle 5, the turning handle 5 is turned in the reverse direction to drive the driving screw 4 to rotate, so that the driving plate 6 and the threaded rod 10 rise, so that the crankshaft oil seal can be easily removed from the engine under the self-locking of the thread of the threaded rod 10, so as to achieve the effect of quick disassembly, and the driving screw 4 is rotated forward, and the driving screw 4 is connected with the threaded connection inside the threaded plate 3, so that the driving plate 6 rotating at the bottom end of the driving screw 4 can be driven to descend, and the lifting and lowering movement of the driving plate 6 will drive the pressing ring 7 to rise and fall synchronously, so that the pressing ring 7 fits tightly against the crankshaft oil seal.

[0032] The mounting mechanism is arranged in the connecting ring 1 for mounting and fixing the crankshaft oil seal. The mounting mechanism comprises a driving plate 6, which is rotatably connected to the bottom end of the driving screw 4 through a rotating shaft. A pressing ring 7 which matches the crankshaft oil seal is fixedly mounted on the bottom side of the driving plate 6. A plurality of slots 8 are provided on the bottom side of the pressing ring 7. The crankshaft oil seal is clamped and placed in the corresponding ring groove. The turning handle 5 is used to rotate the driving screw 4 forward again. The driving screw 4 is connected to the threaded connection inside the threaded plate 3 by the driving screw 4. The driving plate 6 which rotates at the bottom end of the driving screw 4 can be driven to descend. The lifting and lowering movement of the driving plate 6 can drive the pressing ring 7 to rise and fall synchronously, so that the pressing ring 7 can fit tightly to the crankshaft oil seal, thereby pressing the crankshaft oil seal to the inside of the ring groove at the corresponding connection, achieving the effect of crankshaft oil seal installation, enhancing the firmness of the crankshaft oil seal installation, and further enhancing the application range of the device. The slots 8 provided at the bottom of the pressing ring 7 are helpful to prevent the pressing ring 7 from fitting too tightly to the crankshaft oil seal, avoiding the effect of adhesion and difficulty in separation, thereby improving the applicability.

[0033] The disassembly mechanism is arranged in the connecting ring 1 for quickly disassembling the crankshaft oil seal. The disassembly mechanism includes two threaded holes 9. The two threaded holes 9 are both opened inside the driving plate 6. The insides of the two threaded holes 9 are threadedly connected with threaded rods 10. A handle 11 is fixedly provided at the top of the threaded rod 10. A pointed cone 12 for penetrating the crankshaft oil seal is fixedly provided at the bottom of the threaded rod 10. Two through holes 13 for accommodating the pointed cone 12 are opened at the bottom of the pressing ring 7. The two through holes 13 are connected to the threaded holes 9.

[0034] By rotating the threaded rod 10 through the handle 11, the threaded rod 10 is moved up and down in the threaded hole 9, and the pointed cone 12 passes through the through hole 13 at the bottom of the pressing ring 7 and penetrates into the interior of the crankshaft oil seal. As the threaded rod 10 continues to descend, the threaded rod 10 will be threadedly connected with the interior of the crankshaft oil seal. Since the threaded rod 10 itself has a locking effect, the reverse rotation of the handle 5 drives the drive screw 4 to rotate, so that the drive plate 6 and the threaded rod 10 rise. Therefore, under the self-locking of the thread of the threaded rod 10, the crankshaft oil seal can be easily removed from the engine, thereby achieving a quick disassembly effect and improving work efficiency.

[0035] Telescopic rods 14 are symmetrically fixed on the top of the driving plate 6 in pairs, and the top of each telescopic rod 14 is fixed to the bottom side of the fixing frame 2. During the entire disassembly process, the telescopic rods 14 can stabilize the driving plate 6 and ensure the stability and accuracy of the driving plate 6 during the lifting movement.

[0036] The present application can be used in the field of engine disassembly and assembly tools, and can also be used in other fields applicable to the present application.
