Description

Technical Field

[0001] The utility model relates to the technical field of disassembly devices, in particular to an anti-roll bar seat disassembly device. Background Technique

[0002] The anti-roll bar device is a device used to stabilize the left-right swaying movement of the locomotive car body. It provides an anti-torsion counter torque through the deformation of the torsion bar under the action of torsion, thereby buffering the roll tendency generated due to the change of left-right potential energy during the vehicle movement, preventing the car body from rolling relative to the bogie, and improving the ride comfort and safety of the vehicle. During the overhaul of the anti-roll bar device, it is necessary to disassemble and overhaul the torsion bar seat, and check and lubricate the mating surfaces of the steel sleeve, friction sleeve and torsion bar shaft. After passing the overhaul, the anti-roll bar device is assembled again. However, the contact surfaces between the torsion bar shaft and the friction sleeve in the torsion bar seat often rust and cannot be disassembled.

[0003] At present, when disassembling the torsion bar seat, it is necessary to use a Y-shaped simple tooling to clamp the torsion bar seat and use a sledgehammer to strike the Y-shaped tooling in the vertical and horizontal directions. This will not only damage the torsion bar shaft, but also damage the friction sleeve and steel sleeve. Normally, it takes 20-30 minutes to disassemble. In the case of rust between the contact surfaces of the torsion bar shaft and the friction sleeve, it will take nearly 2 hours to disassemble or cannot be disassembled at all, resulting in a large amount of labor consumption and useless work. There will also be certain labor safety risks during the use of the sledgehammer. Content of the Utility Model

[0026] Embodiment:

[0027] Refer to Figure 1 - Figure 2, An anti-roll bar seat disassembly device, including a workbench 1 and a hydraulic rod 2 fixedly installed on the workbench 1, further comprising: a push rod 22 fixedly connected to the telescopic end of the hydraulic rod 2, a push plate 24 is provided at the output end of the push rod 22, a bracket 3 provided on the workbench 1 is connected, U-shaped placement grooves 31 are opened at both ends of the bracket 3 and on the push plate 24, the two sets of placement grooves 31 are aligned with each other, and a passenger car torsion bar 4 can be movably installed inside these placement grooves 31. In this way, during the process of the push rod 22 pushing the push plate 24 to move, the passenger car torsion bar 4 can fall off smoothly. When the push rod 22 pushes the push plate 24 to move, it pushes the torsion bar seat of the passenger car torsion bar 4 to fall off. A connection head 23 is fixedly connected to the output end of the push rod 22, a push plate 24 is fixedly connected to the connection head 23, a slide rail 11 is fixedly connected to the workbench 1, and the push plate 24 is slidably arranged on the slide rail 11 to maintain the smoothness of the push plate 24 during movement, so that the falling-off process of the passenger car torsion bar 4 is smoother.

[0028] An installation frame 12 is fixedly connected to the workbench 1, the hydraulic rod 2 is fixedly installed inside the installation frame 12, the bracket 3 is fixedly installed on the installation frame 12, a fixing plate 21 is fixedly connected to the hydraulic rod 2, and the fixing plate 21 is fixedly connected to the bracket 3.

[0029] Refer to Figure 3 - Figure 4 , Support plates 25 are fixedly connected to both sides of the push plate 24, which play a role in supporting the torsion bar seat and the fixing clamp 28. A clamp plate 28 is slidably arranged on the support plate 25. A number of limit holes 26 are opened on the support plate 25, and the limit holes 26 cooperate with the clamp plate 28 to realize the precise positioning and locking of the clamp plate 28. A chute 27 is opened on the support plate 25, a slider 29 is fixedly connected to the clamp plate 28, and the slider 29 is slidably installed inside the chute 27 to realize the position adjustment in the horizontal direction. The clamp plate 28 is the component that actually contacts the torsion bar seat and applies a clamping force. An insertion rod 210 is slidably arranged inside the clamp plate 28. Plug heads 211 are fixedly connected to both ends of the insertion rod 210, and the plug heads 211 cooperate with the limit holes 26. By adjusting the position of the insertion rod 210, the plug heads 211 can be inserted into or pulled out of the limit holes 26, so as to realize the locking or unlocking of the clamp plate 28. A limit groove 212 is opened on the clamp plate 28, the insertion rod 210 is movably installed inside the limit groove 212, a support spring 214 is fixedly connected to the insertion rod 210, the free end of the support spring 214 is fixedly connected to the limit groove 212, and the support spring 214 provides elastic support for the insertion rod 210 to firmly insert the insertion rod 210 inside the limit groove 212 to prevent the insertion rod 210 from falling off. An adjustment groove 213 is opened on the clamp plate 28, and a convex block on the insertion rod 210 is slidably installed in the adjustment groove 213. The convex block facilitates the operator to pull the insertion rod 210 to adjust the clamp plate 28.

[0030] First, when using the anti-roll torsion bar seat disassembly device, place the bus torsion bar 4 in the U-shaped placement grooves 31 at both ends of the bracket 3, and ensure that the torsion bar seat is located in the U-shaped placement grooves 31 of the push plate 24. Then, according to the size and shape of the torsion bar seat, adjust the position of the clamping plate 28 on the support plate 25 so that it fits tightly with the torsion bar seat. During the adjustment process, the slider 29 on the slidable clamping plate 28 moves inside the slide groove 27 to achieve horizontal position adjustment.

[0031] When the clamping plate 28 is properly adjusted, the plug 211 is pulled out of the limiting hole 26 by pulling the protrusion on the plug rod 210, and the support spring 214 is compressed. Then, the plug rod 210 is released, and the elastic force of the support spring 214 causes the plug rod 210 to reset, and the plug 211 is reinserted into the appropriate limiting hole 26, thereby locking the clamping plate 28.

[0032] After the adjustment and locking of the clamping plate 28 are completed, the hydraulic rod 2 is started, and the push rod 22 pushes the push plate 24 to move along the slide rail 11. Under the push of the push plate 24, the torsion bar seat of the bus torsion bar 4 gradually falls off from the U-shaped placement groove 31 of the bracket 3. Due to the clamping effect of the clamping plate 28, the torsion bar seat can remain stable during the falling process to prevent it from shaking or deflecting, and at the same time prevent the torsion bar seat from falling off from the support plate 25 after the decomposition is completed.

[0033] When the torsion bar seat completely falls off, the projection on the plug rod 210 is pulled again to pull the plug 211 out of the limiting hole 26, thereby releasing the locking state of the clamping plate 28. At this time, the clamping plate 28 can be removed, and the torsion bar seat that has fallen off can be taken out for subsequent processing.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
