Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1:

[0017] This utility model provides a quick disassembly device for forklift maintenance, including a frame 1. A base plate 2 and a worktable 3 are fixedly mounted on the frame 1. An oil tank 4, a pressure pump 5, and a hydraulic cylinder 6 are fixedly mounted on the base plate 2. The pressure pump 5 is connected to the oil tank 4 via a first oil pipe 7 and to the hydraulic cylinder 6 via a second oil pipe 8. The worktable 3 has a through hole 9. A support member 10 is fixedly mounted within the through hole 9 of the hydraulic cylinder 6. Four fixing members 11 are fixedly mounted on the worktable 3. Each fixing member 11 has a first guide groove 12. An X-axis moving platform 13 is movably mounted on the first guide groove 12. The X-axis moving platform 13 has a second guide groove 14. A Z-axis moving platform 15 is movably mounted on the second guide groove 14. A pressure rod 16 is fixedly connected to the Z-axis moving platform 15. The X-axis moving platform 13 has an insertion hole 17. A guide block 19 is fixedly mounted on the insertion hole 17 via a screw 18. A butterfly nut 20 is fixedly connected to the screw 18. The pressure rod 16 is fixedly fitted with a buffer rubber 21, which is made of silicone rubber. The worktable 3 is fixedly fitted with a control box 23 via a vertical rod 22. The control box 23 is fixedly fitted with a display screen 24 and buttons 25.

[0018] Through the above technical solution, this utility model uses a pressure pump 5 to draw hydraulic oil from the oil tank 4 and connects it to a hydraulic cylinder 6 through two second oil pipes 8 to control the extension and retraction of the hydraulic cylinder 6. During operation, the workpiece with the bearing to be disassembled is placed on the worktable 3, so that the bearing of the workpiece is aligned with the support 10. The X-axis moving platform 13 is adjusted to approach the workpiece, and the height of the Z-axis moving platform 15 is adjusted at the same time so that the pressure rod 16 clamps and fixes the workpiece. The hydraulic cylinder 6 is started to drive the support 10 to rise, so that the support 10 presses against the bearing of the workpiece and pushes the bearing out, thus quickly completing the bearing disassembly operation.

[0019] Example 2:

[0020] Example 2:

[0021] In this embodiment, the frame 1 is fixedly mounted with a base plate 2 and a worktable 3. The base plate 2 is fixedly mounted with an oil tank 4, a pressure pump 5, and a hydraulic cylinder 6. The pressure pump 5 is connected to the oil tank 4 via a first oil pipe 7, and to the hydraulic cylinder 6 via a second oil pipe 8. The worktable 3 has a through hole 9, and the hydraulic cylinder 6 is located within the through hole 9 and fixedly mounted with a support member 10. The worktable 3 is fixedly mounted with four fixing members 11, each fixing member 11 having a first guide groove 12, on which an X-axis moving stage 13 is movably mounted. The X-axis moving stage 13 has a second guide groove 14, on which a Z-axis moving stage 15 is movably mounted, and a pressure rod 16 is fixedly connected to the Z-axis moving stage 15.

[0022] In this embodiment, the frame 1 provides an overall support structure to ensure the stability of the device during operation. The base plate 2 serves as the mounting base for the oil tank 4, pressure pump 5, and hydraulic cylinder 6, and these components are securely mounted on the frame 1 via a fixed connection. The oil tank 4 stores hydraulic oil. The pressure pump 5 draws hydraulic oil from the oil tank 4 through the first oil pipe 7 and delivers the hydraulic oil to the hydraulic cylinder 6 through the second oil pipe 8, thereby controlling the extension and retraction of the hydraulic cylinder 6. The hydraulic cylinder 6 is installed in the through hole 9, the design of which allows the hydraulic cylinder 6 to move vertically. The support member 10 is fixed to the top of the hydraulic cylinder 6 for direct contact and pressure on the bearing to be disassembled.

[0023] Four fixing members 11 are evenly distributed on the worktable 3. The first guide groove 12 of each fixing member 11 allows the X-axis moving stage 13 to move horizontally. This design allows the operator to adjust the horizontal distance of the X-axis moving stage 13 according to the size and position of the workpiece. The second guide groove 14 on the X-axis moving stage 13 allows the Z-axis moving stage 15 to move vertically, thereby adjusting the height of the pressure rod 16. The pressure rod 16 is fixed on the Z-axis moving stage 15 and is used to clamp and fix the workpiece during operation to prevent the workpiece from shifting during the pressing process.

[0024] During operation, place the workpiece with the bearing to be disassembled on the worktable 3, aligning the bearing of the workpiece with the support 10. Adjust the X-axis shifter 13 manually or mechanically to bring it closer to the workpiece, while simultaneously adjusting the height of the Z-axis shifter 15 so that the pressure rod 16 can firmly clamp the workpiece. Start the pressure pump 5; hydraulic oil enters the hydraulic cylinder 6 through the second oil pipe 8, driving the hydraulic cylinder 6 to extend and retract upwards. The support 10 rises accordingly and presses against the bearing of the workpiece. Because the hydraulic system provides stable pressure, the support 10 can apply force evenly, pushing the bearing out of the shaft, hub, or housing, completing the rapid disassembly. The entire process is achieved through hydraulic power, is simple to operate, and highly efficient, suitable for disassembling bearings in forklift drive axles, steering axles, and oil pump motors.

[0025] Example 3:

[0026] In this embodiment, the frame 1 is fixedly mounted with a base plate 2 and a worktable 3. An oil tank 4, a pressure pump 5, and a hydraulic cylinder 6 are fixedly mounted on the base plate 2. The pressure pump 5 is connected to the oil tank 4 via a first oil pipe 7 and to the hydraulic cylinder 6 via a second oil pipe 8. The worktable 3 has a through hole 9, and the hydraulic cylinder 6 is located within the through hole 9 and is fixedly mounted with a support member 10. Four fixing members 11 are fixedly mounted on the worktable 3. Each fixing member 11 has a first guide groove 12, and an X-axis moving stage 13 is movably mounted on the first guide groove 12. The X-axis moving stage 13 has a second guide groove 14, and a Z-axis moving stage 15 is movably mounted on the second guide groove 14. A pressure rod 16 is fixedly connected to the Z-axis moving stage 15.

[0027] In this embodiment, the X-axis shift stage 13 is provided with an insertion hole 17, and a guide block 19 is fixedly installed in the insertion hole 17 by a screw 18. A butterfly nut 20 is fixedly connected to the screw 18. By tightening the butterfly nut 20, the X-axis shift stage 13 can be fixed in the desired position. In specific operation, when it is necessary to adjust the position of the X-axis shift stage 13 to adapt to workpieces of different sizes, the operator can first loosen the butterfly nut 20, allowing the X-axis shift stage 13 to slide along the first guide groove 12 to the target position. Then, tighten the butterfly nut 20, and the guide block 19 is pressed against the fixing member 11 by the tightening action of the screw 18, thereby achieving quick fixing of the X-axis shift stage 13. This design simplifies the adjustment process, improves disassembly efficiency, and ensures the stability of the X-axis shift stage 13 during the pressing process of the hydraulic cylinder 6, avoiding the impact of displacement on disassembly accuracy.

[0028] The working principle of this embodiment is as follows: Hydraulic oil is drawn from the oil tank 4 by the pressure pump 5 and delivered to the hydraulic cylinder 6 via the second oil pipe 8, controlling the extension and retraction of the hydraulic cylinder 6. During operation, the workpiece with the bearing to be disassembled is placed on the worktable 3, aligning the bearing of the workpiece with the support 10. The operator adjusts the X-axis moving platform 13 closer to the workpiece, fixes the position of the X-axis moving platform 13 with the butterfly nut 20, and then adjusts the height of the Z-axis moving platform 15 so that the pressure rod 16 clamps and fixes the workpiece. The hydraulic cylinder 6 is activated, driving the support 10 to rise, pressing against the bearing of the workpiece, and using hydraulic pressure to push the bearing out of the workpiece, completing the rapid disassembly operation. Throughout the process, the fixing mechanism of the X-axis moving platform 13 ensures the accurate positioning of the pressure rod 16 and the workpiece, improving the reliability and efficiency of disassembly.

[0029] Example 4:

[0030] In this embodiment, the pressure bar 16 is fixedly fitted with a buffer rubber 21, which is made of silicone rubber. In this embodiment, the height of the pressure bar 16 is adjusted via the Z-axis shift stage 15 to accommodate workpieces of different sizes. The buffer rubber 21 effectively protects the workpiece surface, preventing scratches or indentations during clamping. Silicone rubber has good elasticity and wear resistance, maintaining its cushioning performance even after multiple uses. It also possesses oil resistance and high-temperature resistance, making it suitable for the oil stains and temperature variations commonly encountered in forklift maintenance environments. During operation, when the pressure bar 16 contacts the workpiece, the buffer rubber 21 undergoes elastic deformation, dispersing the clamping force and reducing localized pressure on the workpiece, thereby ensuring the workpiece remains intact during disassembly.

[0031] In practice, the buffer rubber 21 is connected to the end of the pressure rod 16 by adhesive bonding or mechanical fixation to ensure that it will not fall off when clamping the workpiece. The hardness of the silicone rubber is selected to provide sufficient clamping force without damaging the workpiece. When the pressure rod 16 descends to the workpiece surface via the Z-axis shift stage 15, the buffer rubber 21 first contacts the workpiece. As the pressure rod 16 continues to press down, the buffer rubber 21 is gradually compressed until the pressure rod 16 reaches the preset clamping position. During this process, the elastic deformation of the buffer rubber 21 absorbs part of the impact energy, reducing stress concentration on the workpiece surface.

[0032] Furthermore, the design of the buffer rubber 21 takes into account the diversity of workpieces. Its shape and size can be adjusted according to the contact surface of different workpieces to ensure uniform distribution of clamping force. During the disassembly of forklift bearings, the workpieces are usually made of metal, and their surfaces may have oil stains or rust. The oil resistance and chemical corrosion resistance of silicone rubber enable it to work stably for a long time in such environments. The replacement and maintenance of the buffer rubber 21 is also relatively simple. When wear or aging occurs, the buffer rubber 21 can be replaced separately without replacing the entire pressure bar 16, reducing maintenance costs.

[0033] In this embodiment, the application of buffer adhesive 21 not only improves the operational safety of the disassembly device but also extends the service life of the workpiece and reduces workpiece damage caused by the disassembly process. By combining a hydraulic system and a buffer structure, this device achieves efficient and non-destructive disassembly of forklift bearings and is suitable for maintenance operations on forklifts of various specifications.

[0034] Example 5:

[0035] In this embodiment, a control box 23 is fixedly mounted on the workbench 3 via a support pole 22. The control box 23 is equipped with a display screen 24 and buttons 25. In this embodiment, the control box 23 is securely mounted above the workbench 3 via the support pole 22, ensuring clear observation and convenient operation for the operator. The control box 23 integrates an electrical control system, which is connected to actuators such as the pressure pump 5 and hydraulic cylinder 6 via wiring to achieve precise control of the device's movements. The display screen 24 uses liquid crystal display technology to display the working pressure of the hydraulic system, the stroke position of the hydraulic cylinder 6, and operating status information in real time, providing the operator with intuitive data feedback. The buttons 25 include function keys for start, stop, pressure adjustment, and direction control, and feature a waterproof and dustproof design to ensure reliable operation in maintenance environments. With the control box 23, the operator can directly monitor and adjust the disassembly process next to the workbench 3 without frequent relocation, improving operational efficiency and safety.

[0036] The control box 23 is ergonomically designed with an adjustable support pole 22 to accommodate operators of different heights. The display screen 24 has an adjustable angle to prevent glare from affecting visual judgment. The buttons 25 are logically laid out, with frequently used function keys placed within easy reach to reduce operational errors. The control box 23's casing is made of metal, providing excellent heat dissipation and impact resistance. The internal circuit board is shockproof, adapting to the vibrations and noise of the workshop environment. Through the integrated design of the control box 23, centralized control of the hydraulic system and mechanical movements is achieved, simplifying the operation process and reducing operational difficulty.

[0037] In actual operation, when it is necessary to disassemble the forklift bearing, the operator first starts the pressure pump 5 via button 25 on the control box 23 to adjust the working pressure of the hydraulic system. The display screen 24 shows the pressure value in real time, and the operator can adjust the pressure appropriately according to the tightness of the bearing. Subsequently, the positions of the X-axis shift stage 13 and the Z-axis shift stage 15 are adjusted via the control box 23 to ensure that the pressure rod 16 accurately clamps the workpiece. After the workpiece is fixed, the operator controls the hydraulic cylinder 6 via the control box 23 to drive the support component 10 to rise and press the bearing. Throughout the process, the display screen 24 continuously monitors the stroke and pressure changes of the hydraulic cylinder 6. If any abnormality occurs, the operator can immediately stop the operation via button 25 to ensure that the disassembly process is safe and controllable.

[0038] The control box 23 design in this embodiment not only improves the convenience and accuracy of operation, but also enhances equipment safety through real-time monitoring. The fixing method of the upright 22 ensures the stability of the control box 23, avoiding misoperation due to vibration. The reasonable configuration of the display screen 24 and buttons 25 allows even inexperienced operators to quickly master the operation, improving the practicality and applicability of the equipment. Through this design, this application effectively solves the problem of difficult forklift bearing disassembly, achieving fast, safe, and efficient maintenance operations.
