Description

Technical Field

[0001] This invention relates to the field of disassembly device technology, and more specifically, to a coupling disassembly device. Background Technology

[0002] A coupling is a mechanical part mainly used to connect two shafts in different mechanisms, enabling them to rotate together and transmit torque. Disassembly of couplings requires a disassembly device, such as the generator coupling disassembly device described in patent publication number CN209380229U. This device includes a frame, a worktable for supporting the generator, and a slide assembly. The worktable is located on one side of the top of the frame, and a rotating shaft is positioned between the worktable and the frame. One end of the shaft is connected to the frame, and the other end is rotatably connected to the bottom surface of the worktable. A guide rail is located on the other side of the top of the frame. The slide assembly includes a base plate and a support plate. The bottom surface of the base plate has guide grooves that cooperate with the guide rails. The support plate is positioned above the base plate, and a lifting device is located between the base plate and the support plate to lift the support plate. A pushing and separating mechanism is located on the top of the support plate. This invention enables rapid disassembly of generator couplings, improving disassembly efficiency. Simultaneously, the hydraulic system, in conjunction with a three-jaw puller, effectively reduces the labor intensity of operators.

[0003] However, existing disassembly devices are difficult to remove due to the interference fit between the coupling and the shaft, making disassembly with the aid of the device quite strenuous and increasing the pressure requirements of the device. However, excessive pressure from the disassembly device can also damage the original coupling. To address this, this application designs a coupling disassembly device that heats the original coupling before disassembly, causing thermal expansion and reducing the interference fit strength. This reduces the pressure requirements of the disassembly device while also preventing damage to the original coupling. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a coupling disassembly device that solves the problem that the interference fit between the coupling and the shaft increases the difficulty of disassembly during the disassembly process.

[0009] Preferably, the limiting sealing plate has a number of moving slots, and the number of moving slots is the same as that of the flip plate. The flip plate is provided with a flip shaft, which is rotatably connected to the flip frame. A swing seat is fixedly installed at the upper end of the flip plate, and a sliding seat is rotatably installed at the upper end of the swing seat. The sliding seats slide in the corresponding moving slots.

[0010] Preferably, each of the sliding seats has a mating thread on its upper surface, and the bottom of the movable turntable has a control thread. The control thread and several mating threads are threaded together. The lower surface of the movable turntable has an extension sleeve, and a second knob is fixedly installed at the bottom of the extension sleeve.

[0011] Preferably, the extension plate has a mounting groove, and an electric heating plate for heating is installed inside the mounting groove. Cables are provided on the outside of the electric heating plate.

[0012] The rotating support is equipped with several brushes, which are connected to corresponding cables. The rotating sleeve is equipped with an electric slip ring, which is electrically connected to the brushes.

[0013] Preferably, the clamping plate has several grooves, and a floating seat is movably installed inside each groove by a support spring. An auxiliary ball bearing is rotatably installed inside the floating seat.

[0014] Preferably, the drive assembly includes a hollow shaft motor, which is fixedly mounted on the lower surface of the fixed frame. A hollow spline shaft is fixedly mounted on the output end of the hollow shaft motor. A rotating groove is provided on the upper surface of the rotating support. A rotating disk is provided inside the rotating groove. A spline sleeve is fixedly mounted on the upper surface of the rotating disk. The spline sleeve is connected to the hollow spline shaft.

[0015] Preferably, the rotating disk has limit grooves on both sides inside, and a movable slide block is slidably installed in each limit groove. A locking rod is fixedly installed on one side of the movable slide block. A locking slot is opened on the inner wall of the rotating support, and the locking slot and the locking rod are interlocked.

[0016] An extension platform is fixedly installed on the upper side of the movable slide, and a combined screw sleeve is fixedly installed on the outer side of the extension platform. The inner wall of the combined screw sleeve is threadedly engaged with the threaded push rod.

[0017] Preferably, an extension slide groove is provided between the limiting slide grooves, and an extension slide rod is fixedly installed on the outer side of the movable slide on both sides. A threaded sleeve is fixedly installed on one end of the extension slide rod, and the extension slide rod is slidably installed in the extension slide groove.

[0018] The extended slide groove is rotatably installed with a positive and negative lead screw. The body of the positive and negative lead screw is threadedly engaged with the threaded sleeves on both sides. A second bevel gear is provided on one side of the positive and negative lead screw. A first knob is rotatably installed on the upper side of the extended slide groove. A first bevel gear is fixedly installed at the bottom of the first knob. The first bevel gear meshes with the second bevel gear.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Before disassembly, this application fixes the shaft of the coupling to be disassembled within the bearing mounting seat, making it easier to apply force during subsequent disassembly and preventing deviations caused by bearing movement. The drive assembly can control the rotation and lifting of the clamping assembly as needed. Before disassembly, the rotation of the clamping assembly allows the heating structure on the clamping assembly to provide comprehensive and continuous heating to the coupling at its current position, causing thermal expansion of the outer coupling and reducing the connection strength between the interference fit between the coupling and the bearing. Subsequently, the drive assembly lifts the clamping assembly, allowing for rapid disassembly under lower pressure after heating. Compared to the forced pull-out of existing disassembly devices, this application reduces the intensity and avoids damage to the coupling or bearing during disassembly.

[0021] 2. The sliding bracket enables the clamping assembly to move up and down, allowing it to pull out the coupling. The rotational engagement between the rotating sleeve and the rotating support enables the clamping assembly to rotate, facilitating automatic heating of the coupling ear strap by the clamping assembly.

[0022] 3. By rotating the second knob, the movable turntable can be rotated. When the movable turntable rotates, the control thread on the lower surface of the movable turntable will engage with several mating threads. With the limiting engagement between the sliding seat and the moving groove, each sliding seat will move synchronously. In order to realize the clamping operation of multiple clamping plates, the synchronous movement of each sliding seat can pull the swing seat below to swing. Then, the tilting shaft can be used to adjust the angle of the tilting plate, so that the clamping plate at the lower end can perform the clamping operation. The above structure can perform quick synchronous clamping operations, further improving clamping efficiency. It can also make the clamping plate suitable for couplings of different sizes, and the heating plate can also match the size of the coupling, further improving the applicability of this application.

[0023] 4. When heating, the clamping plate will be close to the coupling in advance. In order to avoid wear between the clamping plate and the coupling, auxiliary balls are set between the clamping plate and the coupling. When rotating, the rotation of the auxiliary balls can reduce the friction between them, so as to ensure that the subsequent rotation heating can run for a long time. Furthermore, the support spring can prevent the auxiliary balls from being squeezed and damaged during subsequent disassembly.

[0024] 5. By rotating the first knob, the first bevel gear meshes with the second bevel gear, thereby causing the positive and negative lead screws to rotate inside the expansion groove. The limiting cooperation between the expansion slide rod and the expansion groove allows the positive and negative lead screws to engage with the threaded sleeves on both sides, thereby adjusting the position of the moving slide blocks on both sides to achieve subsequent drive switching.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1 to 16 As shown, a coupling disassembly device includes a placement platform 1, with columns 2 fixedly installed on both sides of the placement platform 1. A fixing frame 3 is fixedly installed on the upper end of the two columns 2. The inside of the two columns 2 is respectively provided with a mounting groove 8. An mounting assembly 5 is installed inside the mounting groove 8 through an upper spring 9. A clamping assembly 6 for clamping and heating the coupling is installed inside the mounting assembly 5. A threaded push rod 10 for supporting the bearing is fixedly installed in the center of the fixing frame 3. An extension rod is threaded inside the threaded push rod 10. A bearing fixing seat 7 for clamping the coupling bearing is fixedly installed in the middle of the placement platform 1. A drive assembly 4 for driving the clamping assembly 6 to rotate and rise is installed at the bottom of the fixing frame 3.

[0044] Before disassembly, this application fixes the shaft of the coupling to be disassembled within the bearing mounting seat 7, making it easier to apply force during subsequent disassembly and preventing deviations caused by bearing movement. The drive assembly 4 can control the rotation and lifting of the clamping assembly 6 as needed. Before disassembly, the rotation of the clamping assembly 6 allows the heating structure on it to provide comprehensive and continuous heating to the coupling at its current position, causing thermal expansion of the outer coupling and reducing the connection strength between the coupling and the bearing through the interference fit. Then, the drive assembly 4 lifts the clamping assembly 6, allowing for rapid disassembly under lower pressure after heating. Compared to the forced pull-out of existing disassembly devices, this application reduces the intensity and avoids damage to the coupling or bearing during disassembly.

[0045] In this application, the upper spring 9 can be used to support the mounting assembly 5 upwards, so that the lower clamping plate 605 is close to the coupling in height.

[0046] In this embodiment, the mounting component 5 includes a sliding bracket 501. The sliding bracket 501 has mounting grooves 8 slidably mounted on both sides and located above the upper spring 9. A rotating sleeve 502 is fixedly mounted in the middle of the sliding bracket 501. A rotating support 503 is rotatably mounted inside the rotating sleeve 502. A clamping component 6 is mounted inside the rotating support 503. A through hole 504 for the threaded push rod 10 is opened in the middle of the rotating support 503. The sliding bracket 501 allows for the lifting and lowering of the clamping component 6, facilitating the clamping component 6 to pull out the coupling. The rotational engagement between the rotating sleeve 502 and the rotating support 503 enables the rotation of the clamping component 6, facilitating subsequent automatic heating of the coupling's ear strap by the clamping component 6.

[0047] In this embodiment, the clamping assembly 6 includes a limiting sealing plate 601, which is fixedly installed inside the rotating support 503. A movable turntable 606 is rotatably installed on the upper side of the limiting sealing plate 601, and a flipping frame 602 is fixedly installed on the lower side of the limiting sealing plate 601. A plurality of flipping plates 603 are provided inside the flipping frame 602, and a clamping plate 605 is installed at the bottom of the flipping plate 603 through an extension plate 604.

[0048] It should be noted that the limiting sealing plate 601 has several moving slots, and the number of moving slots is the same as that of the flip plate 603. The flip plate 603 is provided with a flip shaft 6031, which is rotatably connected to the flip frame 602. A swing seat 6032 is fixedly installed on the upper end of the flip plate 603, and a sliding seat 6033 is rotatably installed on the upper end of the swing seat 6032. The sliding seats 6033 slide in the corresponding moving slots respectively.

[0049] Each sliding seat 6033 has a mating thread 6034 on its upper surface, and a control thread 6061 is provided at the bottom of the movable turntable 606. The control thread 6061 is threadedly engaged with several mating threads 6034. An extension sleeve 6062 is provided on the lower surface of the movable turntable 606, and a second knob 6063 is fixedly installed at the bottom of the extension sleeve 6062.

[0050] Rotating the second knob 6063 drives the movable turntable 606 to rotate. When the movable turntable 606 rotates, the control thread 6061 on the lower surface of the movable turntable 606 engages with several mating threads 6034. Utilizing the limiting engagement between the sliding seat 6033 and the moving groove, each sliding seat 6033 moves synchronously. To achieve the clamping operation of multiple clamping plates 605, the synchronous movement of each sliding seat 6033 pulls the lower swing seat 6032 to swing. Then, the tilting shaft 6031 allows the tilting plate 603 to adjust its angle, enabling the lower clamping plate 605 to perform the clamping operation. This structure allows for quick and synchronous clamping operations, further improving clamping efficiency. Furthermore, the clamping plate 605 is suitable for couplings of different sizes, and the heating plate 6043 can also match the size of the coupling, further expanding the applicability of this application.

[0051] In a specific configuration, the extension plate 604 has a mounting groove 6042, and an electric heating plate 6043 for heating is installed inside the mounting groove 6042. Cables 6041 are installed on the outside of the electric heating plate 6043.

[0052] Several brushes 5031 are installed inside the rotating support 503. The brushes 5031 are connected to the corresponding cables 6041. An electric slip ring 5021 is provided inside the rotating sleeve 502. The electric slip ring 5021 is electrically connected to the brushes 5031.

[0053] An electric slip ring 5021 is provided inside the rotating sleeve 502. When the extension plates 604 rotate, each heating plate 6043 is connected to a brush 5031 via a cable 6041, so that each brush 5031 can be electrically connected to the electric slip ring 5021 to achieve real-time power transmission. This ensures that each heating plate 6043 can continuously heat during rotation. The above structure allows for free control of the heating range. Compared with the prior art of mounting the heating coil on the outer ring of the coupling, which not only requires matching the coupling size but also requires additional implementation steps, this application can achieve efficient and multi-size heating disassembly while realizing heating disassembly, thus improving the applicability of this application.

[0054] In a specific configuration, the clamping plate 605 has several grooves 6051. Each groove 6051 has a floating seat 6053 that is movably installed inside through a support spring 6052. An auxiliary ball bearing 6054 is rotatably installed inside the floating seat 6053.

[0055] During heating, the clamping plate 605 will approach the coupling in advance. To avoid wear between the clamping plate 605 and the coupling, auxiliary balls 6054 are set between the clamping plate 605 and the coupling. During rotation, the rotation of the auxiliary balls 6054 can reduce the friction between them, ensuring that the subsequent rotational heating can run for a long time. Furthermore, during subsequent disassembly, the support spring 6052 can prevent the auxiliary balls 6054 from being squeezed and damaged.

[0056] In this embodiment, the drive assembly 4 includes a hollow shaft motor 401, which is fixedly mounted on the lower surface of the fixed frame 3. A hollow spline shaft 4011 is fixedly mounted on the output end of the hollow shaft motor 401. A rotating groove 403 is provided on the upper surface of the rotating support 503. A rotating disk 402 is provided inside the rotating groove 403. A spline sleeve 4021 is fixedly mounted on the upper surface of the rotating disk 402. The spline sleeve 4021 is connected to the hollow spline shaft 4011.

[0057] By starting the hollow shaft motor 401, the hollow spline shaft 4011 can be driven to rotate. The connection between the hollow spline shaft 4011 and the spline sleeve 4021 allows the rotating disk 402 to rotate continuously, and the distance between the rotating disk 402 and the hollow shaft motor 401 can be adjusted. Thus, the hollow shaft motor 401 can simultaneously meet the needs of rotating and lifting the rotating disk 402.

[0058] In this application, the rotating disk 402 has limit grooves 4023 on both sides inside, and a movable slide block 404 is slidably installed inside each limit groove 4023. A locking rod 4041 is fixedly installed on one side of the movable slide block 404. A locking slot 5032 is provided on the inner wall of the rotating support 503. The locking slot 5032 and the locking rod 4041 are interlocked.

[0059] An extension platform 4042 is fixedly installed on the upper side of the movable slide 404, and a combined threaded sleeve 4043 is fixedly installed on the outer side of the extension platform 4042. The inner wall of the combined threaded sleeve 4043 is threadedly engaged with the threaded push rod 10.

[0060] When the rotating clamping assembly 6 needs to be heated, the sliding block 404 is moved to the outside, so that the locking rod 4041 is inserted into the locking slot 5032, thereby connecting the current rotating disk 402 with the rotating support 503. Then, under the drive of the hollow shaft motor 401, the clamping assembly 6 below is continuously rotated to achieve the rotation heating operation.

[0061] When the lifting clamping assembly 6 needs to be disassembled, the movable slide 404 is moved to the inside, so that the two combined screw sleeves 4043 on both sides are merged together, and the combined screw sleeves 4043 can be threadedly engaged with the threaded push rod 10. Thus, driven by the hollow shaft motor 401, the combined screw sleeves 4043 will rotate around the threaded push rod 10, and the combined screw sleeves 4043 and the lower clamping assembly 6 will be lifted and lowered under the threaded engagement of the threaded push rod 10, so as to realize the disassembly operation.

[0062] Among them, an extension slide 405 is provided between the limiting slide grooves 4023, and an extension slide rod 4044 is fixedly installed on the outer side of the two movable slide blocks 404. A threaded sleeve 4045 is fixedly installed at one end of the extension slide rod 4044, and the extension slide rod 4044 is slidably installed in the extension slide 405.

[0063] Inside the extended slide 405, a positive and negative lead screw 4051 is rotatably installed. The body of the positive and negative lead screw 4051 is threadedly engaged with the threaded sleeves 4045 on both sides. A second bevel gear 4052 is provided on one side of the positive and negative lead screw 4051. A first knob 4022 is rotatably installed on the upper side of the extended slide 405. A first bevel gear 4024 is fixedly installed at the bottom of the first knob 4022. The first bevel gear 4024 meshes with the second bevel gear 4052.

[0064] To switch the drive of the hollow shaft motor 401, the first bevel gear 4024 and the second bevel gear 4052 are engaged by rotating the first knob 4022, thereby causing the positive and negative lead screw 4051 to rotate inside the extended slide groove 405. The limiting cooperation between the extended slide rod 4044 and the extended slide groove 405 allows the positive and negative lead screw 4051 to engage with the threaded sleeves 4045 on both sides, thereby adjusting the position of the two movable slide blocks 404 to achieve subsequent drive switching.

[0065] Working principle of this coupling disassembly device:

[0066] In use, first place the bearing of the coupling to be disassembled in the bearing fixing seat 7. Then, by turning the second knob 6063, the movable turntable 606 can be rotated. When the movable turntable 606 rotates, the control thread 6061 on the lower surface of the movable turntable 606 will be threadedly engaged with several mating threads 6034. The limiting engagement between the sliding seat 6033 and the moving groove will be used to make each sliding seat 6033 move synchronously, so that multiple clamping plates 605 clamp the coupling at the same time.

[0067] Then, by moving the sliding block 404 to the outside, the locking rod 4041 is inserted into the locking slot 5032, thereby connecting the current rotating disk 402 with the rotating support 503. Then, under the drive of the hollow shaft motor 401, the clamping assembly 6 below rotates continuously to achieve the rotation heating operation.

[0068] After heating is completed, the sliding block 404 moves to the inside, so that the combined threaded sleeves 4043 on both sides are merged together, and the combined threaded sleeves 4043 can be threadedly engaged with the threaded push rod 10. Under the drive of the hollow shaft motor 401, the combined threaded sleeves 4043 will rotate around the threaded push rod 10, and under the threaded engagement of the threaded push rod 10, the combined threaded sleeves 4043 and the lower clamping assembly 6 can be raised and lowered. By starting the lifting adjustment, multiple clamping plates 605 can quickly pull out the coupling, thereby realizing the disassembly operation.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
