[0020] Due to the structural characteristics of wheel parts, two threaded holes are usually drilled symmetrically on the wheel during the production process. If there are no threaded holes, they can be used as connecting holes by tapping. Next, install the disassembly device, place the disassembly device telescopic head on the center hole of the wheel shaft end, and connect the two fixed claws to the two threaded holes of the wheel parts. In this way, the disassembly device is fixed to the wheel parts, and the hydraulic cylinder is used to move it downward, so that the two fixed claws drive the wheel parts to separate from the shaft necks that match them, completing the disassembly of the wheel parts.
[0021] For wheel disc parts of different sizes, the position of the fixed claws can be adjusted or the supporting plates of different sizes can be replaced. In order to further reduce the requirements for the working space, the hydraulic telescopic mechanism can be separated from the pressurized control mechanism and connected with a hydraulic pipe, which greatly reduces the working space and working intensity.
[0022] When installing the disassembly device, the telescopic head of the disassembly device is placed on the center hole of the shaft end of the wheel disc, and the left and right fixed claws are respectively connected to the left and right connecting holes of the wheel disc part. The disassembly device is fixed on the wheel disc part, and then the hydraulic cylinder is used to extend and drive the telescopic head to move downward, so that the two fixed claws drive the wheel disc part to separate from the shaft neck that matches them, thereby completing the disassembly of the wheel disc part.
[0023] Left and right clamping jaws: Generally, there are two symmetrical threaded holes on wheel parts. If there is no thread, tapping can be done, and then the left and right clamping jaws are fixed in the threaded holes. The hydraulic telescopic action separates the wheel from the axle to complete the disassembly task. During the disassembly operation, the left and right clamping jaws are fastened to the left and right connecting holes of the parts through threads. The clamping jaws are firmly connected to the wheel, which effectively avoids the slippage phenomenon at the contact point between the clamping jaws and the wheel.
[0024] Support plate: The left and right adjustment slots are left at both ends of the long strip support plate as long holes. The upper end of the clamping claw can move left and right in the long hole to facilitate the adjustment of the position of the clamping claw. When the distances between the process holes on different wheels are different, the disassembly work can be completed by adjusting the positions of the left and right clamping claws, which increases the scope of application of the disassembly device. This structure can realize the convenient replacement of the clamping claws and support plate parts. For parts of different sizes, the disassembly of parts of various specifications can be completed by adjusting the position of the clamping claws or replacing the support plate of the required size.
[0025] The hydraulic telescopic mechanism and the pressurized control mechanism are arranged separately, and the two are connected to each other through hydraulic pipes. When working, the operating panel of the pressurized control device is pressed, and the hydraulic oil enters the telescopic cylinder through the hydraulic pipe to make the hydraulic telescopic rod work, which reduces the working intensity and can realize small space operation; the telescopic head adopts a small volume and portable conical structure design, which has the advantages of small volume, high pressure and easy alignment of the wheel axle center.
