Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, especially to a ball pin dismounting tool. BACKGROUND

[0002] At present, the common ball pin dismounting tools in the market are usually heavy mechanical tools, which are mainly used for dismounting the ball pin connection in vehicles or mechanical equipment. These tools usually have the following forms:

[0003] (1) Hydraulic ball pin dismounting tool. This tool provides enough pressure to push the dismounting process through a hydraulic system, which is usually composed of a pump, oil pipe, pressure gauge and other components. The advantage of the hydraulic dismounting tool is that it can provide a large dismounting force, which is suitable for relatively solid and severely corroded connections. However, this tool also has obvious disadvantages. For example, it is bulky and has poor portability: due to the hydraulic pump and oil pipe components, the hydraulic tool is usually large in size, inconvenient to carry, and requires a large space for use, which limits its use in emergency situations or narrow spaces; it relies on external energy sources: the hydraulic tool usually requires external hydraulic pumps or power support, limiting its application in environments without power supply; high maintenance cost: the complexity of the hydraulic system makes the maintenance and repair of the tool more cumbersome, and it is prone to leakage and other failures.

[0004] (2) Manual ball pin dismounting tool. This tool is usually composed of a manual lever, a compression nut and a pin, and is operated by manual force. The manual tool is relatively light, but it also has some problems. For example, it requires a lot of hand strength: since the manual tool cannot provide the powerful force of the hydraulic tool, a lot of hand strength is required to dismount stubborn ball pins, and long-term use may cause operator fatigue, reducing work efficiency; limited application range: the dismounting force and application range of the manual tool are limited, and it cannot handle most ball pin dismounting work that requires a large dismounting force, especially for large-sized or severely corroded connecting parts, the manual tool often does not work well; inconvenient operation: manual operation requires high skill and experience, and for inexperienced operators, the tool may be damaged or dismounting may fail due to improper operation.

[0005] (3) Impact ball pin dismounting tool. This tool uses the impact force of a metal hammer to strike the pin, thereby completing the dismounting. Its advantages are faster dismounting speed and suitability for loose ball pin dismounting, but its disadvantages are also obvious. For example, low precision: the tool may be damaged due to uneven force or incorrect direction during the impact process, and it is difficult to maintain a certain degree of precision during the operation process, especially when dismounting precision parts, which may be easily damaged; loud noise and strong vibration: the impact tool produces a lot of noise and vibration, which to some extent increases the discomfort and impact on the operator during the operation process, and long-term use may cause operator fatigue.

[0006] The disadvantages of the prior art are summarized as poor portability, dependence on external energy, insufficient dismounting force and inconvenient operation.

Specific implementation

[0035] In order to make those skilled in the art better understand the technical scheme of the utility model, the utility model will be further introduced in detail in conjunction with the drawings below.

[0036] Please refer to Figures 1-6 A ball pin dismounting tool, comprising:

[0037] Assembly base 1 is the structure of assembling main components of the dismounting tool, and the limiting clamp is detachably mounted on the assembly base 1. The limiting clamp is used to make the ball seat of the installed ball pin extend into and be unable to separate from the limiting clamp when the ball pin is pulled out or ejected, that is, to limit the ball seat of the installed ball pin, so that the subsequent ball pin dismounting work can be carried out after the ball seat is limited in the limiting clamp.

[0038] A detachable connecting structure is arranged between the assembly base 1 and the limiting clamp to detachably mount the limiting clamp on the assembly base 1. Specifically, in order to improve the portability and better adaptability of the tool, different sizes of limiting clamps are replaced to adapt to the dismounting work of ball pins of different sizes.

[0039] The assembly base 1 is provided with a dismounting mechanism, and the ball pin in the limiting clamp is dismounted through the dismounting mechanism.

[0040] Further, the limiting clamp comprises a clamping body 2, which is a hollow cylindrical structure. An opening 3 is formed on one side of the clamping body 2 to allow a ball seat for mounting a ball pin to extend in. An avoiding hole 4 is formed on the upper and lower surfaces of the clamping body 2 to allow the ball pin to pass through. Specifically, the ball seat for mounting the ball pin enters the hollow interior of the clamping body 2 through the opening 3, and the rod part of the ball pin passes through the avoiding hole 4 on the upper or lower surface of the clamping body 2, and then extends out to be disassembled by the disassembly mechanism.

[0041] Further, the detachable connecting structure comprises a circular truncated cone body 5 arranged on the clamping body 2 opposite to the side surface on which the opening 3 is located. A cylindrical body 6 is coaxially arranged on the circular truncated cone body 5.

[0042] A circular truncated cone groove 7 is formed on the side surface of the assembly base 1 to allow the circular truncated cone body 5 to be embedded. A plug hole 8 is coaxially formed in the circular truncated cone groove 7 to allow the cylindrical body 6 to be inserted. The plug hole 8 penetrates through the assembly base 1.

[0043] Specifically, when the limiting clamp is replaced or disassembled, the limiting clamp is directly mounted on the assembly base 1 by embedding the circular truncated cone body 5 into the circular truncated cone groove 7 and inserting the plug hole 8 into the plug hole 8. The force direction for pulling out or pushing out the ball pin, that is, the center axis direction of the avoiding hole 4 on the upper and lower surfaces of the clamping body 2, needs to be perpendicular to the center axis direction of the cylindrical body 6, so that the force direction and the support direction are perpendicular, and the limiting clamp is supported on the assembly base 1, so that the circular truncated cone body 5 and the cylindrical body 6 support the limiting clamp.

[0044] Further, the end of the cylindrical body 6 opposite to the circular truncated cone body 5 has an external thread to threadedly connect with a corresponding nut. In order to further fix the limiting clamp on the assembly base 1, after the circular truncated cone body 5 and the cylindrical body 6 are assembled in place, the end of the cylindrical body 6 extends out of the assembly base 1. At this time, the nut is threadedly connected with the external thread of the cylindrical body 6, so that the nut is tightly pressed against the outside of the assembly base 1, thereby firmly fastening the limiting clamp on the assembly base 1, and the disassembly is convenient and fast.

[0045] Further, the disassembly mechanism comprises a support arm 9 arranged on the assembly base 1. A support rib plate 10 is arranged at the end of the support arm 9. An internally threaded pipe 11 is arranged on the support rib plate 10. A threaded rod 12 is arranged in the internally threaded pipe 11 and threadedly connected with the internally threaded pipe 11.

[0046] The threaded rod 12 and the avoiding hole 4 on the assembly base 1 are located on the same axis.

[0047] One end of the threaded rod 12 close to the avoiding hole 4 is provided with a connecting adapter part which can be connected with the connecting part of the ball pin.

[0048] Specifically, the support arm 9 and the support rib plate 10 on the assembly base 1 both serve to support the internally threaded pipe 11 and the threaded rod 12 to the position of the avoiding hole 4 on the clamping body 2, so that the threaded rod 12 is coaxial with the avoiding hole 4 on the assembly base 1. In use, the connecting adapter part can be connected with the ball pin connecting part, and then the threaded rod 12 is rotated, and the threaded rod 12 moves axially during the threaded cooperation between the threaded rod 12 and the internally threaded pipe 11, so as to drive the ball pin to move axially along the threaded rod 12, so as to provide a force for pushing or pulling the ball pin out of the ball seat, and the ball pin is disassembled. During this process, the ball seat on which the ball pin is installed is limited in the limiting clamp to achieve the work of disassembling the ball pin.

[0049] Further, the connecting adapter part includes a rotating connecting block 13, which is a cylindrical structure with an internal cavity structure. A cylindrical head 14 is coaxially arranged on one end of the threaded rod 12 close to the avoiding hole 4. The edge of the cylindrical head 14 protrudes radially from the threaded rod 12. The cylindrical head 14 is located in the cavity structure of the rotating connecting block 13. A limiting hole 15 is provided on the rotating connecting block 13, through which the threaded rod 12 passes, and the cylindrical head 14 cannot be separated.

[0050] A first connecting lug 16 is arranged on one end of the rotating connecting block 13 opposite the limiting hole 15. A first assembly hole 17 is provided on the first connecting lug 16.

[0051] Further, a connecting column 18 is provided. One end of the connecting column 18 is provided with a second connecting lug 19 matched with the first connecting lug 16. A second assembly hole 20 is provided on the second connecting lug 19. The other end of the connecting column 18 is provided with a third connecting lug 21 matched with the ball pin connecting part. A third assembly hole 22 is provided on the third connecting lug 21.

[0052] Specifically, during the rotation and axial movement of the threaded rod 12, in order to prevent the rotation of the threaded rod 12 from affecting the pushing or pulling action of the ball pin, the connecting adapter part is provided. The rotating connecting block 13 of the connecting adapter part is limited and matched with the cylindrical head 14, so that the rotating connecting block 13 can rotate axially relative to the threaded rod 12 without affecting the axial pushing or pulling force of the threaded rod 12. Further, after the third connecting lug 21 on the connecting column 18 is connected with the hole of the ball pin connecting part through the third assembly hole 22, in the same way, the second connecting lug 19 is connected with the first connecting lug 16 through the second assembly hole 20 and the first assembly hole 17, and finally the threaded rod 12 is connected with the ball pin connecting part, so as to realize the pushing or pulling action of the ball pin during the axial movement of the threaded rod 12, and further realize the disassembly of the ball pin.

[0053] The connecting column 18 is detachably connected between the second connecting lug 19 and the rotating connecting block 13, and is further adapted to different structures of the ball pin connecting part, such as a threaded connection form, or the third connecting lug 21 is directly replaced by a flat head to more stably eject the ball pin to realize disassembly.

[0054] In summary, the disassembly tool solves the problems of poor portability, dependence on external energy, insufficient disassembly force, and inconvenient operation in the existing ball pin disassembly tools, effectively improves the disassembly efficiency of the tool, has good convenience and durability, and meets the requirements of high efficiency, portability and reliability of the tool in the modern mechanical maintenance and assembly process.

[0055] The above only describes some exemplary embodiments of the utility model in a descriptive manner, without doubt, for ordinary skilled in the art, under the condition that the spirit and scope of the utility model are not deviated, the described embodiments can be modified in various different ways, therefore, the above drawings and description are illustrative in nature, should not be understood as the limitation of the protection scope of the utility model claims.
