Technical Field

[0001] This invention relates to the field of mechanical engineering technology, and specifically to a tapered flange disassembly and assembly device. Background Technology

[0002] Tapered flanges are generally installed on tapered shafts using an interference fit. The radial pressure generated by the interference fit forms friction, thereby stably transmitting torque, axial force, or combined loads, and ensuring precise alignment of the two parts, reducing transmission runout and errors.

[0003] When installing tapered flanges, the traditional methods are mechanical hammering or heating. However, these methods make it difficult to precisely control the interference fit, which can easily lead to deformation or scratches on the tapered flange or mating shaft, and even reduce the sealing performance and service life of the connection. This is especially true for high-strength alloy workpieces, where the risk of damage is high. Summary of the Invention

[0013] Furthermore, the connector includes an intermediate flange and a sleeve, the sleeve being connected between the intermediate flange and the transition flange, and the intermediate flange being detachably connected to the cylinder barrel of the hydraulic cylinder.

[0024] Specific implementation method one: Combining Figure 1 This embodiment describes a top plate 1, a drive unit, and an adapter flange 4. The top plate 1 is used to connect to the tapered shaft 2. The drive unit has a retractable push rod 3, and the top plate 1 is mounted on the push rod 3. The adapter flange 4 is coaxially arranged with the top plate 1 and fixedly installed on the outside of the top plate 1. The adapter flange 4 is used to connect to the tapered flange 5. When the tapered flange 5 and the tapered shaft 2 are assembled, the top plate 1 is fixedly connected to the tapered shaft 2, and the adapter flange 4 is fixedly connected to or abuts against the tapered flange 5. When the tapered flange 5 and the tapered shaft 2 are disassembled, the adapter flange 4 is fixedly connected to the tapered flange 5, and the top plate 1 is fixedly connected to or abuts against the tapered shaft 2. During installation, the push rod 3 retracts, driving the tapered shaft 2 to be inserted into the tapered flange 5. During disassembly, the push rod 3 extends, pushing the tapered shaft 2 out of the tapered flange 5.

[0025] The tapered flange disassembly and assembly equipment of this embodiment greatly shortens the operation time, reduces manpower input, and significantly improves work efficiency compared with the traditional method. By controlling the extension and retraction of the push rod 3, the advance of the tapered flange 5 can be precisely controlled, which can accurately ensure the appropriate interference fit, effectively guaranteeing the quality of the interference fit connection of the tapered flange 5 and improving the reliability of the connection. There is no need to use traditional methods such as open flame heat fitting on site, avoiding safety hazards such as fire, improving the safety of equipment and personnel, and also reducing problems such as part deformation that may be caused by heat fitting, thus improving the reliability of the equipment.

[0026] Specific Implementation Method Two: Combining Figure 1This embodiment differs from specific embodiment one in that the driving device is a hydraulic cylinder 13. The hydraulic cylinder 13 forms a closed-loop circuit with the pressure control valve 6, hydraulic pump 7, and hydraulic oil tank 8 via a first oil pipe. In this embodiment, the push rod 3 is the piston rod of the hydraulic cylinder 13. The hydraulic cylinder 13 amplifies the force through hydraulic oil pressure and piston area, resulting in a significantly higher output force than electric telescopic rods and pneumatic cylinders of the same volume, making it more suitable for the installation and disassembly of the tapered flange 5. The oil outlet of the hydraulic oil tank 8 is connected to the oil inlet of the hydraulic pump 7 via the first oil pipe. The oil tank is... The pump provides clean hydraulic oil. The hydraulic pump 7 converts mechanical energy into hydraulic energy. The pressurized high-pressure oil is first delivered to the inlet of the pressure control valve 6 through an oil pipe. The pressure control valve 6 receives the high-pressure oil through the inlet, and the regulated oil flows out from the outlet. Excess oil returns to the hydraulic oil tank 8 through the return port of the pressure control valve 6 via the first oil pipe. The qualified pressure oil, regulated by the pressure control valve 6, is delivered to the hydraulic cylinder 13, hydraulic motor, and other actuators through the first oil pipe. After the actuators are driven, the low-pressure return oil flows back to the hydraulic oil tank 8 through the first oil pipe, completing the cycle. Other components and connections are the same as in Specific Embodiment 1.

[0027] Specific implementation method three: Combining Figure 1 This embodiment differs from Specific Embodiment Two in that it also includes a pressure gauge 9. The pressure testing interface of the pressure control valve 6 is connected to the pressure gauge 9 via an adapter. The adapter can be a pressure testing connector, with one end screwed into the pressure testing interface of the pressure control valve 6 and the other end connected to the pressure gauge 9. Other components and connections are the same as in Specific Embodiment Two.

[0028] Specific implementation method four: Combination Figure 1 This embodiment differs from Specific Embodiment Two in that the outer surface of the tapered flange 5 has an oil injection hole, and the inner surface of the tapered flange 5 has an oil guide ring groove communicating with the oil injection hole. The oil outlet of the pressure control valve 6 is connected to the oil injection hole through a second oil pipe. High-pressure oil flows into the inner surface of the tapered flange 5 after passing through the second oil pipe, the oil injection hole, and the oil guide ring groove, thereby playing a lubricating role, preventing wear on the tapered flange 5 and the tapered shaft 2, and extending their service life. Other components and connections are the same as in Specific Embodiment Two.

[0029] Specific Implementation Method Five: Combining Figure 1 This embodiment differs from Specific Embodiment Two in that the transition flange 4 is mounted on the cylinder of the hydraulic cylinder 13 via a connector. The transition flange 4 is connected to the cylinder, which is immovable; therefore, the transition flange 4 is also immovable. The top plate 1 is movable. The installation and removal of the tapered flange 5 and the tapered shaft 2 are achieved through the cooperation of the transition flange 4 and the top plate 1. Other components and connections are the same as in Specific Embodiment Two.

[0030] Specific Implementation Method Six: Combination Figure 1 This embodiment differs from specific embodiment five in that the connecting component includes an intermediate flange 10 and a sleeve 11. The sleeve 11 connects the intermediate flange 10 and the transition flange 4. The intermediate flange 10 is detachably connected to the cylinder of the hydraulic cylinder 13. The intermediate flange 10 and the transition flange 4 are parallel. The sleeve 11 positions the transition flange 4 on one side of the cylinder. The sleeve 11 acts as an intermediate connector, ensuring that the transition flange 4 is positioned within the extension and retraction stroke of the push rod 3, thereby ensuring that the transition flange 4 and the top plate 1 can work together. Other components and connections are the same as in specific embodiment five.

[0031] Specific implementation method seven: Combining Figure 1 This embodiment differs from Specific Embodiment Six in that it has a first external thread on the outer surface of the cylinder and a first internal thread on the inner surface of the intermediate flange 10 that mates with the first external thread. The intermediate flange 10 and the cylinder are connected by a threaded fit, thus achieving a detachable connection. The intermediate flange 10 is mounted on the cylinder near the end of the push rod 3 where it extends and retracts. Other components and connections are the same as in Specific Embodiment Six.

[0032] Specific implementation method eight: Combination Figure 1 This embodiment differs from specific embodiment six in that both ends of the cylinder are connected to the intermediate flange 10 and the transition flange 4 respectively by bolts. The outer surface of the cylinder has multiple circumferentially distributed strip grooves 12. Bolts are installed through the strip grooves 12, pass through the cylinder, and are threadedly connected to the intermediate flange 10 and the transition flange 4. The transition flange 4 and the sleeve 11 are detachably connected, allowing for individual replacement of the transition flange 4, thus accommodating the installation and disassembly of interference-fit tapered flanges 5 of different sizes. Other components and connections are the same as in specific embodiment six.

[0033] Specific Implementation Method Nine: Combining Figure 1 This embodiment differs from specific embodiment one in that the top plate 1 is connected to the conical shaft 2 by bolts, and the transition flange 4 is connected to the conical flange 5 by bolts. In this embodiment, during installation, only the top plate 1 is connected to the conical shaft 2 by bolts, and during disassembly, only the transition flange 4 is connected to the conical flange 5 by bolts. Other components and connections are the same as in any one of specific embodiments one through eight.

[0034] Specific Implementation Method Ten: Combining Figure 1This embodiment differs from specific embodiment one in that the push rod 3 has a second external thread on its outer surface, and the top plate 1 has a second internal thread on its inner surface that mates with the second external thread. The top plate 1 achieves a detachable connection with the push rod 3 through the threaded engagement, allowing the top plate 1 to be replaced individually, thereby adapting to the installation and disassembly of tapered flanges 5 of different sizes with interference fits. Other components and connection relationships are the same as any one of specific embodiments one to eight.

[0035] How to use this implementation method:

[0036] When installing the tapered flange 5, the top plate 1 and the tapered shaft 2 are connected by four bolts. The tapered flange 5 abuts against the transition flange 4. The control push rod 3 retracts, and the push rod 3 drives the tapered shaft 2 from the outside to be inserted into the tapered flange 5 through the top plate 1, thereby realizing the installation of the tapered flange 5. When disassembling the tapered flange 5, the transition flange 4 and the tapered flange 5 are connected by four bolts. The control push rod 3 extends, and the push rod 3 pushes the tapered shaft 2 from the tapered flange 5 through the top plate 1, thereby realizing the disassembly of the tapered flange 5.

[0037] The scope of this invention is not limited to the above-described embodiments; a combination of one or more specific embodiments can also achieve the purpose of the invention.
