Description

Technical Field

[0001] This utility model relates to the technical field of ship maintenance, specifically a non-destructive disassembly and assembly tool for ship outboard motors. Background Technology

[0002] Some components of outboard motors are prone to malfunction or require maintenance during use. Conventional outboard motor underwater propulsion assemblies include a propeller shaft for connecting and mounting the propeller blades. However, because the blades and propeller shaft are constantly submerged in water, they require frequent disassembly for maintenance or replacement. Simultaneously, the outboard motor itself also needs disassembly for inspection and maintenance. Existing disassembly tools, when separating the outboard motor from the propeller shaft, utilize bolt holes on the outboard motor to secure it to a bracket. Once firmly secured, disassembly, inspection, and maintenance can proceed. However, these common disassembly tools still have shortcomings:

[0003] Fixing the outboard motor with bolts is troublesome, as it involves drilling fixing holes in the outboard motor, which damages the structure of the outboard motor itself. Furthermore, when disassembling the blade shaft, a three-jaw puller is usually used to pull the blade shaft out, which can easily damage the threads on the blade shaft. In addition, when the diameter of the blade shaft is small, it is easy to cause unstable clamping. Utility Model Content

[0004] The purpose of this utility model is to provide a non-destructive disassembly and assembly tool for ship outboard motors, in order to solve the problems mentioned in the background art, which are that fixing the outboard motor with bolts is cumbersome, requires drilling fixing holes on the outboard motor, which damages the structure of the outboard motor itself, and when disassembling the propeller shaft, a three-jaw puller is generally used to pull out the propeller shaft, which can easily damage the threads on the propeller shaft, and when the diameter of the propeller shaft is small, it is easy to be unstable in clamping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-destructive disassembly and assembly tool for ship outboard motors, comprising a base bracket, a connecting component fixedly connected to one side of the base bracket, a support plate assembly fixedly connected to one side of the connecting component by bolts, a protective gasket provided on the surface of the support plate assembly, limit components provided on both sides of the surface of the support plate assembly, an outboard motor body provided inside the support plate assembly, a propeller shaft provided at the bottom of the outboard motor body, and a disassembly mechanism threadedly connected to the surface of the propeller shaft.

[0006] Preferably, the connecting assembly includes a connecting plate, which is fixedly connected to the base bracket. The four corners of the connecting plate are provided with first connecting holes, which facilitates the connection of the support plate assembly and provides support.

[0007] Preferably, the support plate assembly includes a mounting plate, with second connection holes at each of the four corners of the mounting plate. A detachable support plate is fixedly connected to one side of the mounting plate, and a protective spacer is provided on the detachable support plate. An organic groove is provided in the middle of the detachable support plate, which is beneficial for limiting and fixing the outboard motor body.

[0008] Preferably, the limiting component includes a limiting block, a limiting block screw hole is provided on one side of the surface of the limiting block, a limiting bolt is connected to the internal thread of the limiting block screw hole, and a support plate screw hole is provided on both sides of the surface of the disassembly and assembly support plate. The limiting bolt passes through the limiting block screw hole and the support plate screw hole, which is conducive to quickly pressing down the outboard motor body.

[0009] Preferably, side wing plates are fixedly connected to both sides of the outboard fuselage, and the upper surface of the side wing plates is in contact with the lower surface of the limiting pressure block.

[0010] Preferably, the disassembly mechanism includes a threaded connecting sleeve. The surface of the blade shaft is provided with a threaded layer. The threaded connecting sleeve is threaded onto the threaded layer. One end of the threaded connecting sleeve is rotatably connected to a rotating shaft. One end of the rotating shaft is fixedly connected to a handle. An impact cylinder is slidably connected to the surface of the rotating shaft. The surface of the impact cylinder is provided with multiple anti-slip grooves. The force generated by sliding the impact cylinder pulls the blade shaft out, which has almost no impact on the threads on the blade shaft. Furthermore, the connection is more secure because it is directly connected by threads.

[0011] Compared with the prior art, the beneficial effects of this utility model are: it is equipped with a targeted disassembly and assembly support plate, which has a groove that allows the outboard motor body to be placed directly inside the groove. The side wing plates on both sides of the outboard motor body are clamped on the disassembly and assembly support plate. At this time, the limiting pressure block is rotated to press it onto the side wing plate, and the limiting bolt is tightened to quickly fix the outboard motor body. It is very convenient and quick, saving time and effort. At the same time, the base bracket is universal, and different support plate components can be replaced to adapt to different specifications of outboard motor bodies, making it more versatile.

[0012] It is also equipped with a disassembly mechanism, the end of which is equipped with a threaded connection sleeve that can be directly connected to the thread on the blade shaft. The blade shaft is pulled out by the force generated by the sliding impact cylinder, which has almost no effect on the thread on the blade shaft. Moreover, the connection is more secure because it is directly connected by the thread. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-5 This utility model provides a non-destructive disassembly and assembly tool for ship outboard motors, including a base bracket 1. A connecting component is fixedly connected to one side of the base bracket 1, and a support plate assembly is fixedly connected to one side of the connecting component by bolts. A protective gasket 5 is provided on the surface of the support plate assembly, and limit components are provided on both sides of the surface of the support plate assembly. An outboard motor body 6 is provided inside the support plate assembly, and a propeller shaft 10 is provided at the bottom of the outboard motor body 6. A disassembly mechanism is threadedly connected to the surface of the propeller shaft 10.

[0021] See Figure 1 , Figure 2 and Figure 5 Furthermore, the connecting assembly includes a connecting plate 2, which is fixedly connected to the base bracket 1. The four corners of the connecting plate 2 are provided with first connecting holes 17. The support plate assembly includes a mounting plate 3, which is provided with second connecting holes 18 at its four corners. A disassembly support plate 4 is fixedly connected to one side of the mounting plate 3. A protective spacer 5 is provided on the disassembly support plate 4. An organic groove 11 is provided in the middle of the disassembly support plate 4. The limiting assembly includes a limiting pressure block 8, which is provided with a pressure block screw hole on one side of its surface. A limiting bolt 9 is connected to the internal thread of the pressure block screw hole. Support plate screw holes are provided on both sides of the surface of the disassembly support plate 4. The limiting bolt 9 passes through the pressure block screw hole and the support plate screw hole. Side wing plates 7 are fixedly connected to both sides of the outboard body 6. The upper surface of the side wing plate 7 is in contact with the lower surface of the limiting pressure block 8.

[0022] In use, the size of the fuselage slot 11 is adapted to the outboard fuselage 6. The outboard fuselage 6 is placed inside the fuselage slot 11. At this time, the two side wing plates 7 are placed above the disassembly support plate 4. A protective pad 5 is provided on the surface of the disassembly support plate 4. The lower surface of the side wing plate 7 is in contact with the surface of the protective pad 5. A protective layer is also provided on the surface of the limiting pressure block 8 that contacts the side wing plate 7 to protect the surface of the outboard fuselage 6. Loosen the limiting bolt 9 so that the limiting pressure block 8 can rotate freely. Rotate it to the surface of the side wing plate 7. Then tighten the limiting bolt 9 to apply pressure to the limiting pressure block 8, thereby pressing the limiting pressure block 8 against the side wing plate 7 to achieve the limiting and fixing of the outboard fuselage 6. It is very convenient and quick.

[0023] See Figure 3 and Figure 4 Furthermore, the disassembly mechanism includes a threaded connecting sleeve 12, the surface of the blade shaft 10 is provided with a threaded layer, the threaded connecting sleeve 12 is threadedly connected to the threaded layer, one end of the threaded connecting sleeve 12 is rotatably connected to a rotating shaft 13, one end of the rotating shaft 13 is fixedly connected to a handle 14, the surface of the rotating shaft 13 is slidably connected to an impact cylinder 15, and the surface of the impact cylinder 15 is provided with multiple anti-slip grooves 16.

Then, hold the handle 14, the diameter of which is larger than the diameter of the rotating shaft 13. The inner diameter of the impact cylinder 15 is slightly larger than the diameter of the rotating shaft 13 but smaller than the diameter of the handle 14. At this time, move the impact cylinder 15 to collide with the connection between the rotating shaft 13 and the handle 14, generating an axial force opposite to that of the blade shaft 10, which will pull the blade shaft 10 out.

[0025] In use, this application embodiment allows for the following: When dealing with outboard motors 6 of different specifications, the support plate assembly can be detached from the connecting plate 2. Each support plate assembly has a motor slot 11 that is compatible with a specific specification of outboard motor 6.

The support plate assembly can be installed onto the connecting plate 2 by passing bolts through the first connecting hole 17 and the second connecting hole 18. After the outboard motor 6 is fixed in place, it can be disassembled and its internal components can be maintained, ensuring the stability of the outboard motor 6. At the same time, depending on the diameter of the blade shaft 10, a matching disassembly mechanism can be replaced. The threaded connecting sleeve 12 of the disassembly mechanism must be compatible with the thread layer size on the blade shaft 10, allowing for quick and convenient disassembly of the blade shaft 10. It should be noted that this utility model is a non-destructive disassembly and assembly tool for ship outboard motors.
