Description

Technical Field

[0001] The utility model relates to the technical field of automobile disassembly tools, in particular to an automobile lower control arm disassembly device and a disassembly tool. Background Art

[0002] During the vehicle test or vehicle maintenance, the lower control arm and the steering knuckle need to be disassembled. The operator first removes the connecting screws between the steering knuckle and the lower control arm. The two parts are fitted with clearance, and can only be disassembled by hammering a small iron cone into the gap between the steering knuckle and the lower control arm or by using a crowbar to pry and disassemble using the lever principle. Such disassembly not only cannot ensure the integrity of the lower control arm, but also causes the steering knuckle to deform, thereby affecting the test, increasing the test cycle, and reducing maintenance efficiency. In addition, due to limited space and difficult operation, it is easy to accidentally touch other nearby samples during the hammering or prying process, resulting in damage to the lower control arm, steering knuckle and surrounding chassis samples, thereby failing to ensure the integrity of the chassis. It is difficult to meet the standard requirements when accuracy or complete disassembly is required. In addition, there is a ball cage at the connection between the lower control arm and the steering knuckle. The disassembly operation is prone to oil leakage and the ball cage is easy to be disconnected, which is a test of the operator's professional and technical ability. The strong disassembly of the operator will not only cause harm to the operator, but also damage the vehicle. Utility Model Content

[0041] According to a first aspect of the utility model, a vehicle lower control arm disassembly device is provided, which includes a driving member 10 and a fixing assembly.

[0042] Hereinafter, the specific structures of the above-mentioned components of the vehicle lower control arm removal device according to the present embodiment will be described.

[0043] In this embodiment, if Figures 1 to 5As shown, the driving member 10 includes a force-applying portion 11 and a connecting portion 12 arranged on the force-applying portion 11, and a protruding flared pin 121 is formed at one end of the connecting portion 12 away from the force-applying portion 11; the fixing assembly includes a fixing platform 21 slidably connected to the connecting portion 12 and a fixing member 22 connected to the fixing platform 21, and a protruding clamping portion 221 is formed on the side wall of the fixing member 22 for clamping to the end of the steering knuckle 40 in the axial direction, so that the automobile lower control arm disassembly device is clamped and positioned with the steering knuckle 40, so that the automobile lower control arm disassembly device can be ... The control arm disassembly device is relatively fixed, thereby providing force support for the rotating drive member 10. After the operator clamps the clamping part 221 on the end of the steering member, the force-applying part 11 is driven to rotate, thereby driving the flared pin 121 to extend into the gap 41 of the steering knuckle 40 to expand the width of the gap 41 for subsequent disassembly. Compared with the disassembly method of hammering an iron spike or prying with a crowbar, the operation is more labor-saving and convenient. What is important is that it can avoid damage to the lower control arm, steering knuckle 40 and other surrounding parts, thereby ensuring the integrity of the chassis and the vehicle.

[0044] Furthermore, in this embodiment, Figure 5 The direction indicated by the middle arrow is the rotation direction of the force applying part 11. During the rotation of the force applying part 11, the force applying part 11 and the gap 41 are coplanar, that is, the rotation direction of the force applying part 11 is located at Figure 5 In the plane of perspective.

[0045] It should be noted that the purpose of rotating the force applying part 11 is to extend the expansion pin 121 into the gap 41 so as to gradually expand the gap 41 to the width required for the subsequent disassembly process. Therefore, it is easier to implement by reciprocatingly rotating the force applying part 11 in a small range.

[0046] In this embodiment, if Figure 1 and Figure 2 As shown, the force-applying portion 11 is formed as a rod-shaped structure, and a gripping portion 111 is formed on the force-applying portion 11 for an operator to grip and apply force. For example, the force-applying portion 11 can be formed as a cylindrical rod-shaped structure, so that the gripping portion 111 is formed as a curved structure to improve the comfort of the operator's grip.

[0047] Furthermore, the connecting portion 12 is arranged on the side wall of the force-applying portion 11, and the connecting portion 12 can be formed into a rod-shaped structure arranged at an angle to the force-applying portion 11, and the length of the connecting portion 12 is smaller than the length of the force-applying portion 11, so as to facilitate the operator to disassemble with less effort; the holding portion 111 and the connecting portion 12 are respectively arranged at both ends of the length direction of the force-applying portion 11, so as to increase the force arm when rotating the force-applying portion 11, thereby saving more effort.

[0048] Furthermore, the flaring pin 121 is formed into a block structure, preferably a flat block structure, so that the flaring pin 121 is formed into a rectangular structure, whose thickness dimension is smaller than the length dimension and the width dimension, and the thickness direction is the same as the width direction of the gap 41, so that the flaring pin 121 can easily extend into the gap 41.

[0049] In an optional embodiment, one end of the flaring pin 121 facing the gap 41 has an inclined chamfer, thereby ensuring that the flaring pin 121 smoothly extends into the gap 41 to improve the reliability of expanding the width of the gap 41.

[0050] In a preferred embodiment, Figure 1 and Figure 2 As shown, the force applying portion 11 is formed as a hollow structure, for example, the force applying portion 11 is formed as a circular tubular structure, which reduces the weight of the driving member 10, so that the automobile lower control arm disassembly device meets the lightweight design requirements, is easy for operators to use, and can also save resources and reduce costs.

[0051] In a preferred embodiment, Figure 1 and Figure 5 As shown, two fixing members 22 are provided, and each fixing member 22 is rotatably connected to the fixing platform 21, and the two fixing members 22 can rotate in a direction relatively close to or away from each other to form a claw structure, so that the clamping portions 221 on the two fixing members 22 are respectively located at the two ends of the axial direction of the steering knuckle 40, so that it can be adapted to steering knuckles 40 of different sizes, and in the process of reciprocating rotation of the driving part, it is ensured that the clamping portion 221 on at least one fixing member 22 can be clamped on the axial end of the steering knuckle 40, thereby avoiding the clamping portion 221 from being separated from the steering knuckle 40 during the rotation process.

[0052] In addition, in this embodiment, if Figure 1 and Figure 4 As shown, the fixed platform 21 is provided with a sliding portion 211 which runs through the main body thereof. The sliding portion 211 may be a sleeve structure or a through-hole structure. The sliding portion 211 is sleeved on the outer wall of the connecting portion 12, so that the distance between the fixed platform 21 and the flared pin 121 can be adjusted, so that the automobile lower control arm disassembly device can be used flexibly, thereby meeting the disassembly requirements of steering knuckles 40 of different sizes.

[0053] Further, in a preferred embodiment, the sliding portion 211 and the connecting portion 12 are clearance-matched, thereby facilitating adjustment.

[0054] Furthermore, in this embodiment, if Figure 1 and Figure 4As shown, a protruding rotating portion 212 is provided on the fixing platform 21, and the rotating portion 212 can be formed as a lug structure extending toward the flared pin 121, so that the fixing member 22 is hinged to the rotating portion 212, thereby facilitating the adjustment of the angle between the fixing member 22 and the fixing platform 21, thereby further meeting the disassembly requirements of steering knuckles 40 of different sizes.

[0055] In this embodiment, if Figure 1 and Figure 3 As shown, the fixing member 22 is formed into a rod-shaped structure, and the clamping portion 221 protrudes outward from the side wall of the fixing member 22, so that the clamping portion 221 is set at an angle with the main body of the fixing member 22; the side wall of the fixing member 22 is also formed with a protruding mounting portion 222, and the mounting portion 222 and the clamping portion 221 can be set at both ends of the fixing member 22 in the length direction; the mounting portion 222 can be formed into a pin structure, and the above-mentioned rotating portion 212 is provided with a through hole for the mounting portion 222 to extend into, so that the fixing member 22 and the fixed platform 21 form a rotating connection.

[0056] Furthermore, an outer wall of the mounting portion 222 is formed with an external thread; the automobile lower control arm disassembly device also includes a fastener 30 threadedly connected to the mounting portion 222, and the fastener 30 can be a nut. The mounting portion 222 passes through the through hole on the rotating portion 212 and is connected to the fastener 30, thereby achieving the locking and fixation of the fixing member 22 relative to the fixed platform 21.

[0057] According to the automobile lower control arm disassembly device of the utility model, the structure is simple and the volume is small. The fixing part is connected with the end of the steering knuckle by clamping, so that the whole device is relatively fixed, thereby providing force support for the rotating driving part; during the rotation of the driving part, the flaring pin can be driven to extend into the gap, so that the width of the gap is increased, thereby facilitating subsequent disassembly; the fixed platform is slidably connected with the connecting part, so that it can adapt to the sizes of various steering knuckles, meet the disassembly requirements of different models, effectively protect the integrity of the lower control arm and surrounding samples, reduce the uncertainty and danger in the disassembly process, ensure the standardized process of the disassembly process, thereby shortening the test cycle and improving the test efficiency. In addition, it also has the advantages of easy operation and reliable use, thereby reducing the labor intensity of operators and ensuring the safety of operators.

[0058] The second aspect of the utility model provides a disassembly tool, including the above-mentioned automobile lower control arm disassembly device, and thus has all the beneficial technical effects of the automobile lower control arm disassembly device, which will not be repeated here.
