Description

Technical Field

[0001] This utility model relates to the field of coupling installation and disassembly technology, and in particular to a flexible installation and disassembly device for couplings. Background Technology

[0002] Currently, in the mechanical field, couplings are widely used as crucial components connecting two shafts or a shaft and a rotating part, enabling them to rotate together and transmit torque. Flexible disassembly is a method of disassembling equipment parts by employing gentle, precise, and controllable techniques and methods, such as using hydraulics, thermal expansion and contraction, chemical loosening agents, and ultrasonic vibration, to avoid excessive impact on the disassembled parts, ensure uniform force distribution, and minimize damage such as wear, deformation, and cracks to the surface and internal structure of the parts. This maintains the original performance and precision of the parts, facilitating subsequent reuse or maintenance.

[0003] Rigid installation and disassembly methods make it difficult to ensure that uniform force is applied to the coupling. When using a puller for disassembly, the installation position of the puller's claws is manually controlled, which is prone to deviation. This causes the coupling to be subjected to uneven tension during disassembly. This uneven force can cause the coupling to twist and deform. In severe cases, it can change the ellipticity of the coupling's inner bore, affecting its fit accuracy with the shaft and reducing the coupling's transmission performance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a flexible installation and disassembly device for couplings.

[0005] This utility model is achieved using the following technical solution: a flexible installation and disassembly device for a coupling, comprising a base, a disassembly port on the top of the base, a pushing component for pushing and disassembling the internal shaft of the coupling at the bottom of the base, a fixing component for fixing the position of the coupling on the base, and an installation component for installing the shaft onto the coupling at the top of the base. The pushing component includes a first hydraulic unit disposed at the bottom of the base, a first push rod fixedly mounted on the pushing end of the first hydraulic unit, and the top end of the first push rod extending upward to the disassembly port side.

[0006] The above technical solution utilizes a first hydraulic unit to provide a stable and uniform driving force, which, compared to traditional rigid installation and disassembly methods, allows for a gentler pushing and installation or disassembly of the internal shaft of the coupling, reducing the risk of damage to the coupling.

[0007] As a further improvement to the above solution, a first support plate is fixedly sleeved on the first hydraulic device, and a first support rod is fixedly installed at each of the four top corners of the first support plate, with the top of each first support rod fixedly installed to the bottom of the base.

[0008] Through the above technical solution, the structure composed of the first support plate and the first support rod plays the role of stabilizing the first hydraulic device, so that the first hydraulic device remains stable during operation, and avoids the first hydraulic device shaking from affecting the pushing effect of the first push rod, thus ensuring the stability and accuracy of the disassembly process.

[0009] As a further improvement to the above solution, a rotating groove is provided on the cylindrical surface of the disassembly port, and a plurality of first rotating columns arranged in a circular array are rotatably installed inside the fixing component. A first fixing plate is fixedly sleeved on the top of each first rotating column, and a second fixing plate is fixedly sleeved on the bottom of each first rotating column.

[0010] With the above technical solution, when it is necessary to fix the coupling, the first fixing plate can rotate around the first rotating column. After adjusting to a suitable angle, it can cooperate with the second fixing plate to lock the coupling, thereby achieving the initial positioning and fixing of the coupling, which facilitates subsequent disassembly operations.

[0011] As a further improvement to the above solution, the bottom end of each of the first rotating columns penetrates the base downward and is equipped with a rotating block with a torsion spring inside. A second rotating column is installed at the bottom of each rotating block, and a push rod is fixedly installed on one side of each of the second rotating columns.

[0012] With the above technical solution, the torsion spring inside the rotating block allows the first rotating column to rotate at the same angle after the second rotating column 404 rotates. It is only necessary to ensure that the first fixed block is in close contact with the shaft surface, which makes it convenient to lock the coupling when disassembling couplings of different sizes.

[0013] As a further improvement to the above solution, a plurality of push grooves arranged in a ring array are formed on the cylindrical surface at the top of the first push rod, and one end of each push rod extends into the interior of the adjacent push groove.

[0014] Through the above technical solution, the push groove and the push rod cooperate with each other. When the first push rod moves upward, the movement of the push groove will push the push rod, converting the linear motion of the first push rod into the circular motion of the push rod, thereby driving the first rotating column and the first fixed plate to rotate, realizing the automatic fixing of the coupling.

[0015] As a further improvement to the above scheme, the middle section of each of the push grooves is inclined.

[0016] Through the above technical solution, the inclined section design of the push groove enables the push rod to drive the first rotating column to rotate more smoothly when it moves in the push groove. Furthermore, the speed and force of the first fixed plate rotation can be adjusted according to different inclination angles, thereby improving the flexibility and stability of the fixed coupling.

[0017] As a further improvement to the above solution, the installation assembly includes four second support rods fixedly installed on the top of the base, each second support rod having a support cylinder slidably sleeved on it, the top ends of the plurality of support cylinders having a second support plate fixedly installed, the second support plate having a second hydraulic actuator fixedly installed, and the pushing end of the second hydraulic actuator having a second push rod fixedly installed.

[0018] Through the above technical solution, the second hydraulic device can push the second push rod to push the shaft, thereby achieving flexible installation of the shaft and coupling. The support cylinder can slide on the second support rod, thereby changing the position of the second hydraulic device and the second push rod to adapt to shafts of different sizes.

[0019] As a further improvement to the above solution, a first fixing hole is provided on one side of the bottom end of each support cylinder, and multiple equally spaced second fixing holes are provided on each second support rod. A limiting plate is provided on the top of the base, and fixing rods are fixedly installed at both ends of one side of the limiting plate. One end of each fixing rod passes through the adjacent first fixing hole and second fixing hole.

[0020] With the above technical solution, when the shafts are of different lengths, the support cylinder can be slid upwards, and then a fixing rod can be inserted into the first fixing hole and the second fixing hole to fix the position of the support cylinder, thereby allowing the position of the second hydraulic device to be adjusted to adapt to shafts of different lengths.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention provides a pushing component and an installation component that offer stable driving force through a first hydraulic actuator and a second hydraulic actuator, as well as a fixing component that automatically fixes the coupling by utilizing the cooperation of a pushing groove and a pushing rod. This allows for flexible disassembly during the installation and disassembly of the coupling, effectively avoiding problems such as excessive impact, uneven force distribution, damage to mating surfaces, and alteration of material properties caused by traditional rigid installation and disassembly methods. This reduces damage to the coupling and improves the quality of installation and disassembly and extends its service life. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Please combine Figures 1-5 This embodiment of a flexible installation and disassembly device for a coupling includes a base 1, a disassembly port 2 on the top of the base 1, a pushing component for pushing and disassembling the internal shaft of the coupling at the bottom of the base 1, a fixing component for fixing the position of the coupling on the base 1, and an installation component for installing the shaft onto the coupling at the top of the base 1.

[0032] The pushing assembly includes a first hydraulic unit 301 disposed at the bottom of the base 1. A first push rod 302 is fixedly installed at the pushing end of the first hydraulic unit 301. The top end of the first push rod 302 extends upward to one side of the disassembly port 2. A first support plate is fixedly sleeved on the first hydraulic unit 301. A first support rod is fixedly installed at each of the four corners of the top of the first support plate. The top end of each first support rod is fixedly installed to the bottom of the base 1.

[0033] The first hydraulic unit 301 provides a stable and uniform pushing force, which can more gently push and disassemble the internal shaft of the coupling compared to the traditional hard disassembly method, reducing the risk of damage to the coupling.

[0034] The structure consisting of the first support plate 5 and the first support rod 6 serves to stabilize the first hydraulic device 301, ensuring its stability during operation and preventing the shaking of the first hydraulic device 301 from affecting the pushing effect of the first push rod 302, thus ensuring the stability and accuracy of the disassembly process.

[0035] A rotating groove 7 is provided on the cylindrical surface of the disassembly port 2. Multiple first rotating columns 401 arranged in a circular array are rotatably mounted inside the fixing assembly. A first fixing plate 402 is fixedly fitted onto the top of each first rotating column 401, and a second fixing plate 406 is fixedly fitted onto the bottom of each first rotating column 401. When it is necessary to fix the coupling, the first fixing plate 402 and the second fixing plate 406 can rotate around the first rotating column 401. After adjusting to a suitable angle, they are used to lock the coupling, achieving initial positioning and fixing of the coupling, facilitating subsequent disassembly operations. The bottom end of the first rotating column 401 passes downward through the base 1 and is equipped with a rotating block 403 with an internal torsion spring. A second rotating column 404 is installed at the bottom of each rotating block 403. A push rod 405 is fixedly installed on one side of each second rotating column 404. The torsion spring inside the rotating block 403 allows the first rotating column 401 and the second rotating column 406 to not rotate at the same angle after the second rotating column 404 rotates. It is only necessary to ensure that the first rotating column 401 is in close contact with the shaft surface, which makes it convenient to lock the coupling when disassembling couplings of different sizes.

[0036] Multiple push grooves 8 arranged in a ring array are provided on the cylindrical surface at the top of the first push rod 302. One end of each push rod 405 extends into the interior of the adjacent push groove 8, and the middle section of each push groove 8 is inclined.

[0037] The push groove 8 and the push rod 405 cooperate with each other. When the first push rod 302 moves upward, the movement of the push groove 8 will push the push rod 405, converting the linear motion of the first push rod 302 into the circular motion of the push rod 405, thereby driving the first rotating column 401, the first fixed plate 402 and the second fixed plate 406 to rotate, so as to realize the automatic fixing of the coupling.

[0038] The mounting assembly includes four second support rods 501 fixedly mounted on the top of the base 1. Each second support rod 501 is slidably fitted with a support cylinder 502. A second support plate is fixedly mounted on the top of the multiple support cylinders 502. A second hydraulic actuator 503 is fixedly mounted on the second support plate. A second push rod 504 is fixedly mounted on the pushing end of the second hydraulic actuator 503. A first fixing hole is opened on one side of the bottom end of each support cylinder 502. Multiple equally spaced second fixing holes are opened on each second support rod 501. A limiting plate 9 is provided on the top of the base 1. Fixing rods 10 are fixedly mounted on both ends of one side of the limiting plate 9. One end of each fixing rod 10 passes through an adjacent first fixing hole and a second fixing hole.

[0039] The second hydraulic actuator 503 pushes the second push rod 504 to push the shaft, thereby achieving flexible installation of the shaft and coupling. The support cylinder 502 can slide on the second support rod 501, thereby changing the position of the second hydraulic actuator 503 and the second push rod 504 to adapt to shafts of different sizes.

[0040] The implementation principle of a flexible installation and disassembly device for a coupling in this embodiment is as follows: when disassembling the coupling, the coupling is first placed inside the disassembly port 2 of the base 1 and rested on the top of the first push rod 302.

[0041] The first hydraulic actuator 301 is activated, which pushes the first push rod 302 upward. As the first push rod 302 moves upward, the coupling and the connected shaft also move upward, and the push groove 8 also moves upward. The inclined section of the push groove 8 pushes the push rod 405, which drives the second rotating column 404 to rotate, thereby causing the rotating block 403 to rotate. The first rotating column 401 rotates accordingly, and the first fixed plate 402 and the second fixed plate 406 fixed on the first rotating column 401 also rotate synchronously. There is space between the first fixed plate 402 and the second fixed plate 406 for the coupling to move up and down, so as to prevent the coupling from directly jamming with the first fixed plate 402 and the second fixed plate 406 when moving up and down.

[0042] When the first fixing plate 402 rotates to the surface of the coupling that is fitted onto the shaft, it limits the upward movement of the coupling. The second fixing plate 406 rotates at the same angle as the first fixing plate 402, thus limiting the downward movement of the coupling. The first push rod 302 continues to move upward, and its top end pushes the bottom of the shaft. Since the coupling is already held in place by the first fixing plate 402, under the continuous thrust of the first push rod 302, the shaft will be pushed from the bottom of the coupling and gradually pushed out of the coupling, thus achieving flexible separation of the shaft from the coupling.

[0043] After disassembly is completed, the first hydraulic unit 301 is shut off, the first push rod 302 descends, and the push rod 405 drives the first rotating column 401 to rotate in the opposite direction under the action of the torsion spring, so that the first fixed plate 402 and the second fixed plate 406 return to their initial positions for the next disassembly operation.

[0044] The internal torsion spring of the rotating block 403 allows the first rotating column 401 to rotate without rotating by the same angle after the second rotating column 404 rotates. It is only necessary to ensure that the first rotating column 401 is in close contact with the shaft surface, which makes it convenient to lock the coupling when disassembling couplings of different sizes.

[0045] When it is necessary to install the shaft and coupling, simply insert the shaft into the coupling manually beforehand to ensure that they are not loose. Then, the worker holds the shaft and places the coupling into the disassembly port 2 of the base 1. The first hydraulic pump 301 is activated, causing the first push rod 302 to move upward. The first fixing plate 402 and the second fixing plate 406 will then lock the coupling in place. At this time, the first push rod 302 is located at the bottom of the coupling and will not be inserted into the inside of the coupling. Since the second fixing plate is located at the bottom of the coupling, it will support the coupling. Then, the worker releases his hand, and the coupling will fall onto the second fixing plate 406. Next, the second hydraulic pump 503 is activated, and the second push rod 504 descends, which will push the shaft on the coupling, thereby inserting the shaft into the inside of the coupling.

[0046] Finally, the pushing end of the second hydraulic unit 503 retracts, the worker holds the shaft on the coupling, the first hydraulic unit 301 retracts to release the limiting effect on the coupling, and the worker can then remove the coupling and shaft together.

[0047] When the shafts are of different lengths, the support cylinder 502 can be slid upwards, and then the fixing rod 10 can be inserted into the first fixing hole and the second fixing hole to fix the position of the support cylinder 502, thereby allowing the position of the second hydraulic device 503 to be adjusted to accommodate shafts of different lengths.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
