Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance, in particular to a wheel hub brake drum disassembly device. Background Art

[0002] During the repair and maintenance of the car, the removal of the wheel hub brake drum is a common and important work step. The brake drum is an important component in the brake system. Its function is to withstand the friction and heat generated during braking to ensure that the car can brake safely and effectively. However, as time goes by and the frequency of vehicle use increases, the brake drum may need to be replaced due to wear, aging or damage.

[0003] Traditional brake drum disassembly methods often rely on manual operation, using tools such as wrenches and hammers for disassembly. This method has many shortcomings. First, manual disassembly is inefficient, especially when facing some brake drums with high tightness, which requires a lot of time and effort; second, the brake drum is exposed to the high temperature caused by braking for many years and is prone to rust and sticking. The traditional disassembly method uses a hammer to hit the brake drum to separate it from the wheel core. Safety hazards are prone to occur during manual disassembly. Improper operation may cause personal injury or equipment damage; third, traditional disassembly methods are difficult to ensure the accuracy and consistency of disassembly, and are prone to secondary damage to the brake system. In order to solve the above problems, some brake drum disassembly equipment has also appeared on the market. These equipment have improved the disassembly efficiency to a certain extent, but there are still some limitations. For example, some equipment needs to cooperate with manual use of air cannons and screws to disassemble the brake drum, which is cumbersome and has a low safety factor.

[0004] In view of this, we propose a wheel hub brake drum disassembly device. Utility Model Content

[0005] The purpose of the utility model is to provide a wheel hub brake drum disassembly device which has a simple disassembly method and can reduce damage to the brake system, so as to solve the problems raised in the above-mentioned background technology.

[0007] A wheel hub brake drum disassembly device includes a frame, a support leg and a base, the support leg is installed between the frame and the base, one end of the frame is provided with a disassembly head for fixing the outer edge of the brake drum, and clamping arms for fixing the inner edge of the brake drum are symmetrically provided on both sides of the disassembly head. A bracket for placing a driving mechanism is provided at the inner end of the frame away from the disassembly head, and a movable adjustment pad is provided between the bracket and the disassembly head.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1 As shown, this embodiment provides a wheel hub brake drum disassembly device, including a frame 4, a support leg 6 and a base 8, the support leg 6 is installed between the frame 4 and the base 8, considering the fixing of the brake drum, a disassembly head 2 for fixing the outer edge of the brake drum is provided at one end of the frame 4, and clamping arms 1 for fixing the inner edge of the brake drum are symmetrically provided on both sides of the disassembly head 2, considering the separation of the brake drum from the wheel hub, a bracket 5 for placing a driving mechanism is provided at the inner end of the frame 4 away from the disassembly head 2, and a movable adjusting pad 3 is provided between the bracket 5 and the disassembly head 2, and the adjusting pad 3 is driven by the driving mechanism to move in the frame 4, and the brake drum and the wheel hub are separated by the action force and reaction force.

[0023] The improvement of this embodiment lies in that: by arranging a clamping arm 1 and a disassembly head 2 at one end of the frame 4, the brake drum is fixed by utilizing the cooperation between the clamping arm 1 and the disassembly head 2, so as to facilitate the subsequent disassembly of the brake drum; by arranging a movable adjusting pad 3 between the bracket 5 and the disassembly head 2, after the driving mechanism is placed on the bracket 5, the driving mechanism drives the adjusting pad 3 to squeeze the wheel hub, and the reaction force acts on the inner edge of the brake drum through the frame 4 and the clamping arm 1. As the driving mechanism continues to advance, the wheel hub is separated from the brake drum, effectively ensuring that the brake drum is not damaged, thereby realizing the disassembly work efficiently and safely, and avoiding the use of hammering. Improper operation may easily cause personal injury or equipment damage.

[0024] Taking into account that the presence of the wheel hub bolts prevents the disassembly head 2 from contacting the outer edge of the brake drum, the disassembly head 2 is welded and fixed to one end of the frame 4. The disassembly head 2 is provided with a plurality of through holes corresponding to the wheel hub bolts. Through the through holes, the disassembly head 2 passes through the wheel hub bolts and contacts the outer edge of the brake drum, thereby effectively avoiding damage or malfunction caused by the relative force between the disassembly head 2 and the wheel hub bolts, thereby improving the efficiency and safety of the disassembly work, and greatly reducing the potential risks caused by improper operation.

[0025] In order to fix the brake drum, the clamping arm 1 is rotatably connected to the frame 4. The end of the clamping arm 1 away from the frame 4 is provided with a clamping claw bent toward the disassembly head 2. The inner edge of the brake drum is fixed by the bent clamping claw, thereby increasing the stability of subsequent separation of the wheel hub and the brake drum, reducing potential risks caused by improper operation, and ensuring the safety and reliability of the entire maintenance process.

[0026] like Figure 2 As shown, considering the stability of the adjusting pad 3 when it moves, slide grooves 41 are symmetrically provided on both sides of the frame 4, and clamping blocks are symmetrically provided at both ends of the adjusting pad 3. The clamping blocks of the adjusting pad 3 are slidably connected in the slide grooves 41, thereby limiting the moving direction of the adjusting pad 3 and avoiding the direction from being offset when the adjusting pad 3 moves, thereby ensuring the accuracy and stability of the entire operation process.

[0027] In order to facilitate the driving mechanism to apply force to the adjusting pad 3, a fixing port 31 is provided on the side of the adjusting pad 3 close to the bracket 5. In this embodiment, the driving mechanism can adopt hydraulics or other methods. By controlling the output force and speed of the driving mechanism, the disassembly force and speed can be accurately controlled to ensure a smooth and efficient disassembly process. The driving mechanism of this embodiment uses a hydraulic rod, and an extrusion block 32 is symmetrically provided on the side of the adjusting pad 3 away from the fixing port 31. The extrusion block 32 passes through the disassembly head 2 to act on the wheel hub to apply force.

[0028] Taking into account that during actual disassembly, the height of the wheel hub brake drum may be inconsistent with the height of the frame 4, the height of the frame 4 needs to be adjusted. Therefore, one end of the support leg 6 is fixed to the bottom of the frame 4, and a connecting rod 7 is rotatably connected between the end of the support leg 6 away from the frame 4 and the base 8. The two connecting rods 7 away from the clamping arm 1 are fixed with a push rod 9. The push rod 9 applies force upward or downward to drive the connecting rod 7 to rotate, and further drives the frame 4 to move downward or upward, so as to meet the height of the wheel hub brake drum, facilitate the subsequent fixation of the clamping arm 1 and the disassembly head 2, and at the same time, facilitate the movement of the entire disassembly device. A number of universal wheels are provided at the bottom of the base 8, and the position of the disassembly device can be conveniently adjusted through the push rod 9 and the universal wheels.

[0029] In summary, the working principle of this solution is as follows:

[0030] The disassembly device is moved, and the height of the frame 4 is adjusted by applying an upward or downward force to the hand push rod 9, so that the through hole of the disassembly head 2 passes through the wheel hub bolt and contacts the outer edge of the brake drum, and the clamping arm 1 is rotated to allow the clamping claw of the clamping arm 1 to fix the inner edge of the brake drum. The hydraulic rod is selected, and the piston rod of the hydraulic rod is clamped in the fixing port 31 of the adjusting pad 3. The other end of the hydraulic rod is placed on the bracket 5, and the hydraulic rod is started. Under the action of the hydraulic pressure, the piston rod pushes the adjusting pad 3 to slide in the slide groove 41 of the frame 4. With the push of the piston rod, the extrusion block 32 of the adjusting pad 3 passes through the disassembly head 2 to contact the wheel hub and exert a force on the wheel hub. The reaction force acts on the inner edge of the brake drum through the frame 4 and the clamping arm 1. The wheel hub is separated from the brake drum by the continuous advancement of the hydraulic rod.

[0031] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0032] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
