Description
Technical Field
[0001] This utility model relates to the field of automotive repair technology, and in particular to a hydraulic automotive steering ball joint disassembly and assembly tool. Background Technology
[0002] For example, Chinese Patent No. CN212311883U discloses a new type of special tool for disassembling and assembling the inner ball joint of an automotive steering gear. The length of the entire device can be adjusted by a telescopic rod to adapt to different disassembly and assembly conditions. Then, the inner ball joint is disassembled and assembled by a rotating rod. It is highly practical. By setting up a disassembly and assembly cylinder and a spiral disassembly and assembly block, the spiral disassembly and assembly block in the disassembly and assembly cylinder can adapt to different types of screws, thus enabling the disassembly and assembly of inner ball joints of different types.
[0003] However, steering ball joints are often connected to steering knuckles using tapered pins and nuts. This connection method utilizes the wedging effect of the tapered pin to tightly bind the ball joint and steering knuckle together, and then further tightens it with a nut to ensure the stability of the connection. However, this also increases the difficulty of disassembly. The disassembly and assembly tool in the above application only uses a disassembly and assembly cylinder and a spiral disassembly and assembly block to clamp the tapered pin. When force is applied for disassembly, slippage will occur, which requires a lot of physical strength and time. Moreover, when slippage occurs, the disassembly and assembly tool is very likely to damage the mating surfaces of the steering ball joint and steering knuckle, resulting in scratches and deformation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic automotive steering ball joint disassembly and assembly tool, which solves the technical problems of easy slippage, time-consuming and labor-intensive process, and easy scratches and deformation of the steering ball joint during disassembly. This tool achieves the goal of quickly and safely disassembling and assembling the steering ball joint.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hydraulic automotive steering ball joint disassembly and assembly tool, including a sleeve installed at the bottom of a cylinder, disassembly and assembly mechanisms for locking and disassembling the steering horn connection are provided on both sides of the sleeve, and a wrench mechanism for disassembling and assembling the steering horn connection nut is provided on the cylinder.
[0006] The disassembly and assembly mechanism includes connecting blocks installed at the upper and lower ends of the sleeve side, and a threaded rod is installed between the two connecting blocks. A nut is threadedly connected to the threaded rod, and a hinge seat sleeved on the threaded rod is rotatably connected to the bottom of the nut. A connecting rod is rotatably connected to the hinge seat through a rotating shaft, and a locking block is installed at the bottom of the connecting rod. An assistive component for easy disassembly and assembly is provided on the cylinder.
[0007] A further improvement is that the assist component includes a through hole in the middle of the cylinder, and a movable assist rod is slidably connected in the through hole. Both ends of the movable assist rod are equipped with limiting blocks larger than the diameter of the movable assist rod.
[0008] A further improvement is that trapezoidal protrusions are installed in a ring array inside the sleeve, and the trapezoidal protrusions are installed upside down on the inner wall of the sleeve.
[0009] A further improvement is that the wrench mechanism includes a telescopic slide rod that is slidably connected to a groove on the cylinder, and a handle is installed on the top of the telescopic slide rod. A fixed jaw is fixedly installed on one side of the handle, and a movable jaw is slidably connected on the other side. An opening adjustment nut for adjusting the jaw spacing is installed on the handle, and a locking component for fixing the height adjustment of the telescopic slide rod is installed on the cylinder.
[0010] A further improvement is that the locking assembly includes a locking hole on the top side of the cylinder, and a spring groove is provided in the locking hole. A locking pin is inserted into the locking hole, and a compression spring installed in the spring groove is sleeved on the locking pin.
[0011] A further improvement is that locking holes are also vertically and equidistantly provided on the side of the telescopic slide rod, and a strip groove is provided on the telescopic slide rod.
[0012] By employing the above technical solution, this utility model provides a hydraulic automotive steering ball joint removal and installation tool, which has at least the following beneficial effects:
[0013] 1. This utility model uses a trapezoidal protrusion installed inverted inside the sleeve to lock conical pins of different diameters. It works in conjunction with a locking block to lock the connection between the steering ball head and the steering horn, thereby preventing slippage during disassembly and assembly, which could lead to scratches or even damage and deformation of the steering ball head.
[0014] 2. This utility model improves the versatility of the device by turning the nut, causing it to rotate upward on the threaded rod, thereby driving the hinge seat to rise on the threaded rod, which in turn drives the locking block to rise and abut against the ball joint and steering knuckle of different cars for locking.
[0015] 3. This utility model can disassemble nuts of different sizes for different cars by using the combination of fixed jaws and movable jaws. In addition, the wrench can be adjusted by using a telescopic slide rod to adapt to the disassembly and assembly of steering ball joints in narrow spaces, making it more convenient and faster.

[0029] 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.
[0030] Example 1
[0031] Given that existing technologies often result in slippage during steering ball joint disassembly, which is time-consuming, labor-intensive, and prone to scratches and deformation, this embodiment provides a hydraulic automotive steering ball joint disassembly and assembly tool. Please refer to... Figures 1-5This embodiment provides a hydraulic automotive steering ball joint removal and installation tool, which can quickly and safely remove and install steering ball joints. The tool includes a sleeve 2 installed at the bottom of a cylinder 1. The sleeve 2 has removal and installation mechanisms 3 on both sides for locking and installing the steering knuckle connection. The cylinder 1 has a wrench mechanism 4 for removing and installing the steering knuckle connection nut. The removal and installation mechanisms 3 lock the steering ball joint and the steering knuckle connection, thereby preventing the sleeve 2 from slipping and scratching the steering ball joint, improving both removal and installation efficiency and safety. Furthermore, the wrench mechanism 4 facilitates loosening the nut at the steering ball joint connection, completing the entire removal and installation process.
[0032] Because existing technology makes it easy for the steering ball joint to slip during disassembly, which is time-consuming, labor-intensive, and prone to scratches and deformation, this device is equipped with a disassembly and assembly mechanism 3. The disassembly and assembly mechanism 3 includes connecting blocks 31 installed at the upper and lower ends of the side of the sleeve 2, and a threaded rod 32 is installed between the two connecting blocks 31. A nut 33 is threaded onto the threaded rod 32, and a hinge seat 34 sleeved on the threaded rod 32 is rotatably connected to the bottom of the nut 33. A connecting rod 35 is rotatably connected to the hinge seat 34 through a rotating shaft, and a locking block 36 is installed at the bottom of the connecting rod 35. An assistive assembly is provided on the cylinder 1 to facilitate force application for disassembly and assembly. When disassembling the steering ball joint, sleeve 2 is fitted onto the top of the tapered pin, and then locking block 36 is placed at the connection between the steering ball joint and the steering knuckle. Then, nut 33 is turned to rotate upward on threaded rod 32, thereby driving hinge seat 34 to rise on threaded rod 32, which in turn drives locking block 36 to rise and abut against the connection between the two to lock. Then, cylinder 1 is turned to rotate sleeve 2, thereby disassembling the tapered pin and completing the disassembly of the steering ball joint. The height of locking block 36 can be adjusted up and down according to the connection position of steering ball joint and steering knuckle of different cars, thereby improving the versatility of the device.
[0033] Since it is inconvenient to apply force when rotating the cylinder 1, the device is also equipped with an assist component 37. The assist component 37 includes a through hole 371 in the middle of the cylinder 1, and a movable assist rod 372 is slidably connected in the through hole 371. Both ends of the movable assist rod 372 are equipped with limiting blocks 373 that are larger than the diameter of the movable assist rod 372. When the locking block 36 is tightened, the movable assist rod 372 is held, which makes it easy to apply force to drive the sleeve 2 to rotate and disassemble the steering ball joint.
[0034] Since the steering ball joints of different cars have different diameters, their tapered pins also vary in size. Therefore, trapezoidal protrusions 38 are installed in a ring array inside the sleeve 2 of this device, and the trapezoidal protrusions 38 are installed upside down on the inner wall of the sleeve 2. When the sleeve 2 is fitted onto the top of the tapered pin, the trapezoidal protrusions 38 installed upside down inside it lock the tapered pins of different diameters, preventing slippage.
[0035] Since the nuts at the ball joints of different cars are of different sizes, the device is also equipped with a wrench mechanism 4. The wrench mechanism 4 includes a telescopic slide rod 41 that is slidably connected to a groove on the cylinder 1. A handle 42 is installed on the top of the telescopic slide rod 41. A fixed jaw 43 is fixedly installed on one side of the handle 42, and a movable jaw 44 is slidably connected on the other side. An opening adjustment nut 45 for adjusting the jaw spacing is installed on the handle 42. A locking component 46 for fixing the height adjustment of the telescopic slide rod 41 is installed on the cylinder 1. The fixed jaw 43 is fitted against one side of the nut, and then the opening adjustment nut 45 is moved to move the fixed jaw 43 to the other side of the nut, thereby disassembling and assembling nuts of different sizes.
[0036] Example 2
[0037] Because the space at the steering ball joint connection is small, it is necessary to extend the telescopic slide rod 41 to fit the wrench onto the nut. However, if the telescopic slide rod 41 is not fixed, it will slide up and down inside the cylinder 1 when force is applied, affecting the force application and disassembly. Therefore, based on Embodiment 1, as... Figures 1-5 As shown, the device is also provided with a locking component 46, which includes a locking hole 461 opened on the top side of the cylinder 1, and a spring groove 462 is provided in the locking hole 461. A locking pin 463 is inserted into the locking hole 461, and a compression spring 464 installed in the spring groove 462 is sleeved on the locking pin 463.
[0038] The telescopic slide rod 41 also has locking holes 461 vertically and equidistantly opened on its side, and a strip groove is opened on the telescopic slide rod 41. Pulling the locking pin 463 compresses the compression spring 464, causing it to slide out of the locking hole 461 on the telescopic slide rod 41. Then, pull the telescopic slide rod 41 to the required length, and then release the locking pin 463. At this time, the compression spring 464 returns to its original position and drives the locking pin 463 to slide into the other locking holes 461 on the telescopic slide rod 41, thereby completing the fixation of the telescopic slide rod 41 and preventing the telescopic slide rod 41 from sliding up and down, which would affect the application of force.
