Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts disassembly, in particular to a non-destructive disassembly tool for automobile wheel ends. Background Technique

[0002] The automobile wheel end generally refers to the wheel-end reducer of the automobile, which is the last-stage speed reduction and torque increase device in the automobile transmission system. The use of the wheel-end reducer can meet the conditions of the same total transmission ratio, reduce the loads of components such as the transmission, drive shaft, main reducer, differential, and half shaft, reduce the size, and enable the drive axle to obtain a larger ground clearance. It is widely used in heavy trucks, large buses, off-road vehicles, and some other large industrial and mining applications.

[0003] However, when the existing wheel end is disassembled, the connection of the wheel-end flange is generally chiseled manually between the wheel-end flange connections with a hammer and a chisel. Since the internal components of the wheel-end reducer are relatively precise, the vibration generated by the hammer impact is likely to cause damage to the internal parts. In view of the above problems, the inventor proposes a non-destructive disassembly tool for automobile wheel ends to solve the above problems. Content of the Utility Model

[0004] In order to solve the problem that the connection of the wheel-end flange is generally chiseled manually between the wheel-end flange connections with a hammer and a chisel, and the vibration generated by the hammer impact is likely to cause damage to the internal components; the purpose of the utility model is to provide a non-destructive disassembly tool for automobile wheel ends.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A non-destructive disassembly tool for automobile wheel ends, including a bottom plate, a moving plate is slidably arranged on the top surface of the bottom plate, an installation plate is slidably arranged on one side of the moving plate, a vertical rod is fixedly arranged on one side of the installation plate, a fixed disk is fixedly arranged on one side of the vertical rod, a fixing member is fixedly arranged on the outer surface of the fixed disk, a movable rod is slidably penetrated through the fixing member, a toothed plate is fixedly arranged at one end of the movable rod, a chisel head is fixedly arranged at the end of the toothed plate far away from the movable rod, a rotating shaft is fixedly arranged on one side of the fixed disk, a first gear is rotatably sleeved on the outer surface of the rotating shaft, the first gear meshes with the toothed plate, an internal gear ring is rotatably arranged on one side of the fixed disk, the internal gear ring meshes with the first gear. First, move the device to one side after the hub is disassembled, and then under the cooperation of the electric slide rail and the electric slider, the height of the installation plate can be adjusted, so as to be applicable to wheel-end assemblies of different heights. Push the device to make the fixed disk and the sleeve cover the outside of the wheel-end assembly (the center position of the hub of the non-disassembled wheel-end assembly, and the flange of the wheel-end assembly is connected to the hub flange through bolts), and by opening the electric push rod, the arc-shaped plate is clamped on the outer surface of the wheel-end assembly;

[0006] By turning on the second motor, the second gear rotates, which in turn drives the inner gear ring to drive the guide member to slide in the guide groove, prompting the inner gear ring to rotate. When the inner gear ring rotates on one side of the fixed disk, the inner gear ring drives the first gear to rotate on the outer surface of the rotating shaft. At the same time, the toothed plate drives the movable rod to slide in the fixed member, and then the chisel head slowly moves towards the connection between the wheel side assembly flange and the hub flange, and separates it by the extrusion force, avoiding damage to internal parts caused by vibration during the disassembly of the wheel side assembly. When the chisel head slowly chisels the connection of the wheel side assembly flange, by turning on the first motor, the threaded rod rotates, and then the movable plate slowly slides on the top surface of the bottom plate. At this time, the wheel side assembly moves synchronously with the sleeve, separating the wheel side assembly from the vehicle hub, and completing the disassembly of the wheel side assembly.

[0007] Preferably, a second motor is installed on one side of the fixed disk. The output end of the second motor is fixedly provided with a second gear, which meshes with the inner gear ring. A guide groove is formed in the fixed disk, and a guide member is fixedly provided on one side of the inner gear ring, and the guide member slides in the guide groove.

[0008] Preferably, a sleeve is fixedly provided on one side of the mounting plate. An electric push rod is installed on the outer surface of the sleeve, and the output end of the electric push rod is fixedly provided with an arc-shaped plate.

[0009] Preferably, an electric slide rail is installed in the movable plate. An electric slider is fixedly provided on one side of the mounting plate, and the electric slider slides in the electric slide rail. A first motor is installed on one side of the bottom plate. The output end of the first motor is fixedly provided with a threaded rod. A threaded block is fixedly provided at the bottom end of the movable plate, and the threaded block is threadedly sleeved on the outer surface of the threaded rod.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. In the present utility model, when the inner gear ring rotates on one side of the fixed disk, the inner gear ring drives the first gear to rotate on the outer surface of the rotating shaft. At the same time, the toothed plate drives the movable rod to slide in the fixed member, and then the chisel head slowly moves towards the connection between the wheel side assembly flange and the hub flange, and separates it by the extrusion force, avoiding damage to internal parts caused by vibration during the disassembly of the wheel side assembly;

[0012] 2. In the present utility model, when the chisel head slowly chisels the connection of the wheel side assembly flange, by turning on the first motor, the threaded rod rotates, and then the movable plate slowly slides on the top surface of the bottom plate. At this time, the wheel side assembly moves synchronously with the sleeve, separating the wheel side assembly from the vehicle hub, and completing the disassembly of the wheel side assembly.
