[0034] Example

[0035] The ball joint pin disassembly tool provided in this embodiment, such as Figures 1-2 As shown, it includes: screw 1, crossbar 2, caliper 3, adjusting nut 4, and pressing platform 5, wherein:

[0036] The crossbar 2 passes through the caliper 3 and is slidably connected to the caliper 3. The caliper 3 is used to engage the axle arm. The screw 1 passes through the center hole of the crossbar 2 in a vertical direction. The adjusting nut 4 is sleeved on the screw 1 and located below the crossbar 2. The adjusting nut 4 is threadedly connected to the screw 1, and the upper part of the adjusting nut 4 is fixedly connected to the bottom of the crossbar 2. The pressing platform 5 is sleeved on the bottom end of the screw 1. The pressing platform 5 is used to abut the end of the ball head pin.

[0037] The ball joint disassembly tool using the above-mentioned technical solution, through the cooperation of screw 1, crossbar 2, caliper 3, adjusting nut 4 and pressing platform 5, utilizes the threaded connection between adjusting nut 4 and screw 1 and the fixed connection between adjusting nut 4 and crossbar 2. When screw 1 is rotated, the pressing platform 5 can apply a downward force to the ball joint, while the caliper 3 applies an upward force to the axle arm, thereby separating the ball joint from the axle arm. Compared with the knocking method, this structure can separate the two through a smooth force, reducing damage to the ball joint and axle arm.

[0038] Specifically, in this embodiment, the bottom end of the caliper 3 is integrally formed with a hook, which can be securely locked onto the bottom of the axle arm. The integrally formed hook at the bottom end of the caliper 3 enhances the connection stability between the caliper 3 and the bottom of the axle arm, prevents the caliper 3 from slipping off during force application, ensures the stability of the disassembly process, and thus reduces accidental damage to components caused by the loosening of the caliper 3.

[0039] Specifically, in this embodiment, an operating block 6 is fixedly installed on the upper end of the screw 1, and an insertion hole 7 is provided on the operating block 6. The screw 1 and the adjusting nut 4 achieve relative lifting and lowering through threaded engagement. The operating block 6 and the insertion hole 7 at the upper end of the screw 1 facilitate the rotation of the screw 1 with the aid of tools such as insert rod-shaped tools, making the operation more labor-saving; the threaded engagement between the screw 1 and the adjusting nut 4 can convert rotational motion into relative lifting and lowering linear motion, achieving smooth force transmission and ensuring uniform force on the ball joint pin and the axle arm.

[0040] Specifically, in this embodiment, the bottom surface of the pressing platform 5 is a planar structure, which is used to fit against the top plane of the ball head pin, and the diameter of the pressing platform 5 is larger than the diameter of the top plane of the ball head pin. The planar structure of the bottom surface of the pressing platform 5 fits against the top plane of the ball head pin, which can make the end of the ball head pin evenly stressed and avoid excessive local stress that could damage the ball head pin; the diameter of the pressing platform 5 is larger than the diameter of the top plane of the ball head pin, which can fully cover the end of the ball head pin and prevent the edge of the pressing platform 5 from causing additional damage to the ball head pin.

[0041] Specifically, in this embodiment, the outer diameter of the adjusting nut 4 is larger than the diameter of the central hole of the crossbar 2. This larger outer diameter prevents the adjusting nut 4 from passing through the central hole of the crossbar 2, ensuring the stability of the fixed connection structure between the adjusting nut 4 and the bottom of the crossbar 2. This guarantees that force is effectively transmitted from the adjusting nut 4 to the crossbar 2, achieving synchronous movement between the two.

[0042] Specifically, in this embodiment, the inner wall of the catch hook is provided with anti-slip texture, which is used to increase the friction between the catch hook and the axle arm. The anti-slip texture on the inner wall of the catch hook can increase the friction between the catch hook and the axle arm, further improve the stability of the connection between the caliper 3 and the axle arm, prevent relative slippage during the force process, and ensure the reliability of the disassembly process.

[0043] Specifically, in this embodiment, the crossbar 2 is provided with scale markings, which are used to indicate the position of the caliper 3 on the crossbar 2. The scale markings on the crossbar 2 can intuitively indicate the position of the caliper 3, making it easy to quickly adjust the caliper 3 to a symmetrical force or suitable working position, improving operating efficiency, while ensuring that the force exerted by the caliper 3 on the axle boom is balanced, reducing component damage caused by positional deviation.

[0044] Specifically, in this embodiment, the pressing platform 5 is detachably connected to the screw 1, and the size of the pressing platform 5 can be changed according to the specifications of the ball head pin. The detachable connection and interchangeable size of the pressing platform 5 and the screw 1 enable the tool to be adapted to ball head pins of different specifications, improving the tool's versatility and applicability, eliminating the need to design separate tools for different ball head pins, and reducing usage costs.

[0045] Specifically, in this embodiment, the caliper 3 is made of alloy steel, and the clamping surface of the caliper 3 is coated with an anti-corrosion coating made of polyurethane. The use of alloy steel in the caliper 3 enhances its structural strength and wear resistance, ensuring that it is not easily deformed or damaged when subjected to large forces, thus extending its service life; the anti-corrosion coating on the clamping surface prevents the caliper 3 from rusting, while reducing scratch damage to the anti-corrosion layer on the surface of the axle boom.

[0046] Specifically, in this embodiment, the screw 1, crossbar 2, adjusting nut 4, and pressing platform 5 are all made of alloy steel. The use of alloy steel in the screw 1, crossbar 2, adjusting nut 4, and pressing platform 5 ensures that these main load-bearing components have high strength and rigidity, making them less prone to damage when transmitting and bearing disassembly forces, thus ensuring the overall stability and reliability of the tool structure and extending its service life.

[0047] In summary, the working principle of the ball joint pin disassembly tool provided in this embodiment is as follows:

[0048] This ball joint removal tool achieves ball joint removal through the coordinated operation of its components. The screw 1 is threadedly connected to the adjusting nut 4, and the upper part of the adjusting nut 4 is fixedly connected to the bottom of the crossbar 2. The crossbar 2 is slidably connected to the caliper 3. When the screw 1 is rotated, utilizing the threaded transmission characteristics, the screw 1 moves up and down relative to the adjusting nut 4. Since the adjusting nut 4 is fixed to the crossbar 2, the crossbar 2 moves along with the adjusting nut 4, thereby driving the caliper 3 to move, causing the caliper 3 to apply an upward force to the axle arm. Simultaneously, the downward pressure platform 5, fitted onto the bottom end of the screw 1, moves with the screw 1, applying a downward force to the ball joint. Under the action of these two opposing forces, the ball joint gradually separates from the axle arm.

[0049] How to use

[0050] 1. Adjust the position of caliper 3 on crossbar 2 so that caliper 3 can be engaged on the axle boom, and ensure that the hook at the bottom of caliper 3 is firmly engaged at the bottom of the axle boom.

[0051] 2. Move the crossbar 2 and the screw 1 so that the pressing platform 5 is aligned with and abuts the end of the ball head pin.

[0052] 3. Insert the rod-shaped tool into the socket 7 of the operating block 6, and rotate the operating block 6 to drive the screw 1 to rotate.

[0053] 4. As the screw 1 rotates, the pressing platform 5 moves downward to apply a downward force to the ball joint pin, while the caliper 3 moves upward to apply an upward force to the axle arm until the ball joint pin is completely separated from the axle arm.

[0054] 5. After separation, rotate screw 1 in the opposite direction to reset the pressing platform 5 and caliper 3, then remove the tool.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
