Description

Technical Field

[0001] This utility model relates to the field of auxiliary tool technology, specifically to an auxiliary tool for disassembling drive shafts. Background Technology

[0002] In related technologies, to prevent the drive shaft from detaching from the gearbox during driving, the drive shaft and the gearbox output shaft bearings are interference-fitted. The drive shaft is also designed with a fixing structure to prevent detachment. When repairing and maintaining the drive shaft, it is necessary to disassemble the drive shaft.

[0003] A search revealed Chinese patent CN208759455U, which discloses an auxiliary tool for disassembling a forklift mast pin. The tool includes a slide rod, a sliding hammer mounted on the slide rod, and a bolt connector mounted on one end of the slide rod. One end of the slide rod is fixedly connected to a handle with a limiting plate, and the other end is detachably connected to the bolt connector. There is one or more sliding hammers, each capable of reciprocating along the slide rod. This utility model uses a two-section slide rod, sliding hammers mounted on the slide rod, handles with limiting plates at both ends of the slide rod, and bolt connectors to form an auxiliary tool. The structure is simple, assembly is quick and convenient, and the bolt connector engages with the process hole of the pin. By driving the sliding hammer to strike the limiting plate, the pin is pulled out, reducing the difficulty of disassembling the pin and preventing damage to its appearance. The tool is highly effective.

[0004] However, the above design still has shortcomings. When the drive shaft is disassembled, multiple disassembly heads are usually required due to the different diameters of the drive shaft. However, in actual use, the connection between the disassembly head and the slide bar is relatively fixed, making it inconvenient to disassemble and assemble. It cannot meet the needs of different scenarios and the performance is poor. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tool for disassembling drive shafts, which solves the problem mentioned in the background art that when disassembling drive shafts, multiple disassembly heads are usually required due to the different diameters of the drive shafts. However, in actual use, the connection between the disassembly head and the slide bar is relatively fixed, which makes it inconvenient to disassemble and assemble, and cannot meet the needs of different scenarios, resulting in poor performance.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A drive shaft disassembly aid includes a mounting frame. A transmission screw is threaded through the top of the mounting frame. A rotating rod is fixedly connected to the top of the transmission screw. A circular block is fixedly connected to the bottom of the rotating rod. A slot is formed on the lower surface of the circular block. A locking block is movably disposed inside the slot. Positioning holes are formed on both outer walls of the locking block. A disassembly head is fixedly connected to the bottom of the locking block. Fixing grooves are formed on both outer walls of the circular block. Rotating plates are rotatably disposed inside the fixing grooves. Connecting rods are fixedly connected to the sides of the two rotating plates that are close to each other. Threaded rods are fixedly connected to the sides of the two connecting rods that are close to each other. A moving block is threadedly connected to the outer wall of the threaded rod. A crossbar is movably disposed through the upper surface of the moving block. A transmission block is fixedly connected to the bottom of the moving block. Positioning rods are fixedly connected to the sides of the two transmission blocks that are close to each other, and one end of the positioning rod is movably disposed inside the positioning hole.

[0008] Preferably, the upper surface of the mounting frame is provided with a threaded hole adapted to the transmission screw, and the mounting frame is threadedly connected to the transmission screw through the threaded hole on its surface.

[0009] Preferably, a fixing screw hole is provided on the wall of the fixing groove, and a fixing screw is movably disposed through the surface of the rotating plate, with one end of the fixing screw threaded inside the fixing screw hole.

[0010] Preferably, support plates are fixedly connected to both outer walls of the mounting frame, and support blocks are fixedly connected to the bottom of the support plates.

[0011] Preferably, the surface of the support plate is provided with a through thread for a limiting screw, and a limiting block is fixedly connected to the side of the two limiting screws that are close to each other.

Furthermore, after a new disassembly head is installed, the fixing screw is passed through the rotating plate and screwed into the fixing screw hole to fix the rotating plate and prevent it from rotating, thereby improving the stability of the disassembly head after installation. This solves the problem that when disassembling drive shafts, due to the different diameters of the drive shafts, multiple disassembly heads are usually required. However, in actual use, the connection between the disassembly head and the slide bar is relatively fixed, making disassembly and assembly inconvenient and failing to meet the needs of different scenarios, resulting in poor performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The drive shaft disassembly auxiliary tool includes a mounting frame 2. A transmission screw 5 is threaded through the top of the mounting frame 2. A rotating rod 1 is fixedly connected to the top of the transmission screw 5. A round block 9 is fixedly connected to the bottom of the rotating rod 1. A slot 17 is formed on the lower surface of the round block 9. A locking block 18 is movably arranged inside the slot 17. Positioning holes 16 are formed on both outer walls of the locking block 18. A disassembly head 10 is fixedly connected to the bottom of the locking block 18. Fixing grooves 22 are formed on both outer walls of the round block 9. Rotating plates 19 are rotatably arranged inside the fixing grooves 22. The two rotating plates 19 are fixed on the side closest to each other. A connecting rod 20 is fixedly connected to the two connecting rods 20. A threaded rod 13 is fixedly connected to the side of the two connecting rods 20 that are close to each other. A moving block 12 is threadedly connected to the outer wall of the threaded rod 13. A crossbar 11 is movably provided through the upper surface of the moving block 12. A transmission block 14 is fixedly connected to the bottom of the moving block 12. A positioning rod 15 is fixedly connected to the side of the two transmission blocks 14 that are close to each other. One end of the positioning rod 15 is movably provided inside the positioning hole 16. A threaded hole adapted to the transmission screw 5 is opened through the upper surface of the mounting frame 2. The mounting frame 2 is threadedly connected to the transmission screw 5 through the threaded hole opened on its surface.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in use, when it is necessary to disassemble and replace the disassembly head 10, the rotating plate 19 can be rotated. The rotation of the rotating plate 19 drives the threaded rod 13 to rotate via the connecting rod 20. The rotation of the threaded rod 13 drives the moving block 12 to move. The movement of the moving block 12 drives the transmission block 14 to move. The movement of the transmission block 14 drives the positioning rod 15 to move away from the positioning hole 16 until the positioning rod 15 disengages from the positioning hole 16. Then, the disassembly head 10 is moved downwards until the locking block 18 disengages from the locking groove 17, thereby completing the disassembly of the disassembly head 10. Similarly, the disassembly head 10 can be installed, which facilitates the disassembly of the disassembly head 10. The disassembly and assembly process facilitates better fulfillment of usage needs in different scenarios, resulting in good performance. Furthermore, once the new disassembly head 10 is installed, the fixing screw 23 passes through the rotating plate 19 and is screwed into the fixing screw hole 21, which secures the rotating plate 19 and prevents it from rotating, thus improving the stability of the disassembly head 10 after installation. This solves the problem that when disassembling drive shafts, multiple disassembly heads 10 are typically required due to the different diameters of the drive shafts. However, in actual use, the relatively fixed connection between the disassembly head 10 and the slide bar makes disassembly and assembly inconvenient, failing to adequately meet the usage needs of different scenarios and resulting in poor performance.

[0024] The wall of the fixed groove 22 is provided with a fixed screw hole 21. A fixed screw 23 is movably provided through the surface of the rotating plate 19, and one end of the fixed screw 23 is threaded inside the fixed screw hole 21. Support plates 3 are fixedly connected to both outer walls of the mounting frame 2. Support blocks 8 are fixedly connected to the bottom of the support plates 3. Limiting screws 4 are threaded through the surface of the support plates 3. Limiting blocks 7 are fixedly connected to the side of the two limiting screws 4 that are close to each other. Limiting pads 6 are fixedly connected to the side of the two limiting blocks 7 that are close to each other. The limiting pads 6 are made of rubber.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, when the drive shaft needs to be disassembled, the device is placed above the drive shaft to be disassembled, and the disassembly head 10 is placed on the outer wall of the drive shaft. Then, the limiting screw 4 is rotated, which drives the limiting block 7 to move until the limiting block 7 contacts the outer wall of the device. Then, the rotating rod 1 is rotated, which drives the transmission screw 5 to rotate, which drives the round block 9 to rotate, which drives the disassembly head 10 to rotate, thereby realizing the disassembly of the drive shaft. The operation is simple and the disassembly efficiency is high.

[0026] Working principle: In this application, when the drive shaft needs to be disassembled, the device is placed above the drive shaft to be disassembled, and the disassembly head 10 is fitted onto the outer wall of the drive shaft. Then, the limiting screw 4 is rotated, which drives the limiting block 7 to move until the limiting block 7 contacts the outer wall of the device. Then, the rotating rod 1 is rotated, which drives the transmission screw 5 to rotate, which drives the circular block 9 to rotate, which drives the disassembly head 10 to rotate, thereby realizing the disassembly of the drive shaft. The operation is simple and the disassembly efficiency is high. Secondly, when the disassembly head 10 needs to be disassembled and replaced, the rotating plate 19 can be rotated. The rotation of the rotating plate 19 drives the threaded rod 13 to rotate through the connecting rod 20, which in turn drives the threaded rod 13 to rotate. The moving block 12 moves, which drives the transmission block 14 to move. The transmission block 14 moves, which drives the positioning rod 15 to move away from the positioning hole 16 until the positioning rod 15 disengages from the positioning hole 16. Then, the disassembly head 10 moves downward until the locking block 18 disengages from the locking groove 17, thus completing the disassembly of the disassembly head 10. Similarly, the disassembly head 10 can be installed. By facilitating the disassembly and assembly of the disassembly head 10, it is easier to meet the usage needs of different scenarios and has a good performance. At the same time, after the new disassembly head 10 is installed, the fixing screw 23 is passed through the rotating plate 19 and screwed into the fixing screw hole 21 to fix the rotating plate 19 and prevent it from rotating, thereby improving the stability of the disassembly head 10 after installation.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
