Description

Technical Field

[0001] The present invention relates to the technical field of disassembly devices, and more particularly to a coupling disassembly device. Background Art

[0002] A coupling is a mechanical part mainly used to connect two shafts in different mechanisms so that they can rotate together and transmit torque. And when disassembling the coupling, a disassembly device is needed for disassembly. For example, a generator coupling disassembly device with the patent publication number CN209380229U includes a frame, a workbench for supporting the generator, and a slide table assembly. The workbench is arranged on one side of the top of the frame. A rotating shaft is arranged between the workbench and the frame. One end of the rotating shaft is connected to the frame, and the other end of the rotating shaft is rotatably connected to the bottom surface of the workbench. A guide rail is arranged on the other side of the top of the frame. The slide table assembly includes a bottom plate and a support plate. A guide groove for cooperating with the guide rail is arranged on the bottom surface of the bottom plate. The support plate is arranged above the bottom plate. A lifting device is arranged between the bottom plate and the support plate. The lifting device is used to realize the lifting of the support plate. A pushing and separating mechanism is arranged on the top of the support plate. This utility model can realize the rapid disassembly of the generator coupling and improve the disassembly efficiency of the coupling. At the same time, the hydraulic system cooperates with the three-jaw puller, which can effectively reduce the labor intensity of the operators.

[0003] However, when the existing disassembly devices are used for disassembly, it is difficult to take out the coupling due to the interference fit between the coupling and the rotating shaft. Therefore, it is also quite laborious to use the disassembly device for disassembly, which also increases the requirement for the pressure intensity of the disassembly device. However, if the pressure of the disassembly device is too large, it will damage the original coupling. For this reason, this application designs a coupling disassembly device that can heat the original coupling before disassembly to make the coupling expand thermally and reduce the interference fit strength, reducing the requirement for the pressure intensity of the disassembly device and avoiding the situation that the original coupling will be damaged at the same time.

[0012] Preferably, the driving assembly includes a hollow shaft motor fixedly installed on the lower surface of the fixed frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Before disassembly, the rotating shaft of the coupling to be disassembled is fixed in the bearing fixing seat in this application, so that it is easier to exert force during subsequent disassembly to avoid deviation during disassembly due to the movement of the bearing. The driving assembly can respectively control the rotation and the rise of the clamping assembly as needed, so that before disassembly, the heating structure on the clamping assembly can rotate to continuously and comprehensively heat the coupling at the current position by using the clamping assembly, so that the coupling on the outside expands thermally, thereby reducing the connection strength between the interference fit between the coupling and the bearing. Subsequently, the driving assembly is used to raise the clamping assembly, so that the clamping assembly can be quickly disassembled under the condition of lower pressure intensity after heating. Compared with the forced pulling out of the existing disassembly device, this application can reduce the strength and avoid damage to the coupling or the bearing during disassembly.

[0016] 2. The lifting movement of the clamping assembly can be realized through the sliding bracket, so as to facilitate the clamping assembly to pull out the coupling. Through the rotational cooperation between the rotating sleeve and the rotating support, the rotational operation of the clamping assembly can be realized, so as to facilitate the subsequent full-automatic heating of the coupling ear strap by the clamping assembly.

[0017] 3. Rotating the second knob can drive the movable turntable to rotate. When the movable turntable rotates, the control thread on the lower surface of the movable turntable will be in thread cooperation with several mating threads, and the limiting cooperation between the sliding seat and the moving groove is utilized, so that each sliding seat moves synchronously in position. In order to realize the clamping operation of multiple clamping plates, through the synchronous movement of each sliding seat, the swinging seat below can be pulled to swing, and then the turning plate can be adjusted in angle by using the turning shaft, so that the clamping plate at the lower end can perform the clamping operation. Through the above structure, fast synchronous clamping operation can be carried out, further improving the clamping efficiency, and the clamping plate can also be suitable for couplings of different sizes, and the electric heating plate can also match the size of the coupling, further expanding the application scope of the present application.

[0018] 4. When heating, since the clamping plate will approach the coupling in advance, in order to avoid abrasion between the clamping plate and the coupling, auxiliary balls are arranged between the clamping plate and the coupling. Then, during rotation, the self-rotation of the auxiliary balls can reduce the friction between them, ensuring the long-term operation of the subsequent rotational heating. And when disassembling later, the support spring can prevent the auxiliary balls from being damaged due to extrusion.

[0019] 5. Rotating the first knob drives the first bevel gear to mesh with the second bevel gear, so that the positive and negative lead screw rotates inside the expansion chute. Among them, the limiting cooperation between the expansion slide rod and the expansion chute is utilized, so that the positive and negative lead screw is in thread cooperation with the thread sleeves on both sides, and then the position adjustment of the moving slide seats on both sides is realized to achieve the subsequent drive switching.

[0022] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 16 shown, a coupling disassembly device includes a placement table 1. Columns 2 are fixedly installed on both sides of the placement table 1. A fixed frame 3 is fixedly installed at the upper ends of the two columns 2. Installation chutes 8 are respectively formed inside the two columns 2. An installation component 5 is installed inside the installation chute 8 through an upward spring 9. A clamping component 6 for clamping and heating the coupling is installed inside the installation component 5. A threaded ejector rod 10 for supporting the bearing is fixedly installed at the center of the fixed frame 3. An extension rod is provided with a thread inside the threaded ejector rod 10. A bearing fixing seat 7 for clamping the coupling bearing is fixedly installed in the middle of the placement table 1. A driving component 4 for driving the clamping component 6 to rotate and rise is installed at the bottom of the fixed frame 3.

[0024] Before disassembly in this application, the rotating shaft of the coupling to be disassembled is fixed in the bearing fixing seat 7, so that it is easier to exert force during subsequent disassembly and avoid deviation during disassembly due to the movement of the bearing. Through the driving component 4, the rotation of the clamping component 6 and the rising of the clamping component 6 can be respectively controlled as needed. Thus, before disassembly, the heating structure on the clamping component 6 can be used to rotate the clamping component 6 to continuously and comprehensively heat the coupling at the current position, causing the coupling on the outside to expand thermally, thereby reducing the connection strength between the interference fit between the coupling and the bearing. Subsequently, the driving component 4 is used to raise the clamping component 6, so that the clamping component 6 can be quickly disassembled under the condition of lower pressure intensity after heating. Compared with the forced extraction of the existing disassembly device, this application can reduce the strength and avoid damage to the coupling or bearing during disassembly.

[0025] In this application, the upward spring 9 can be used to support the installation component 5 upward, so that the height of the lower clamping plate 605 is close to the coupling.

[0026] In this embodiment, the installation component 5 includes a sliding bracket 501. The two sides of the sliding bracket 501 are slidably installed inside the installation chute 8 and are located above the upper top spring 9. The middle part of the sliding bracket 501 is fixedly installed with a rotating sleeve 502. Inside the rotating sleeve 502, a rotating support 503 is rotatably installed. Inside the rotating support 503, a clamping component 6 is installed. A through hole 504 for passing the threaded ejector rod 10 is opened in the middle part of the rotating support 503. The lifting movement of the clamping component 6 can be realized through the sliding bracket 501, so as to facilitate the clamping component 6 to pull out the coupling. Through the rotational cooperation between the rotating sleeve 502 and the rotating support 503, the rotational operation of the clamping component 6 can be realized, so as to facilitate the subsequent full-automatic heating of the coupling ear strap by the clamping component 6.

[0027] In this embodiment, the clamping component 6 includes a limiting sealing plate 601. The limiting sealing plate 601 is fixedly installed inside the rotating support 503. An activity turntable 606 is rotatably installed above the limiting sealing plate 601. A flipping frame 602 is fixedly installed below the limiting sealing plate 601. A number of flipping plates 603 are arranged inside the flipping frame 602. The bottom of the flipping plate 603 is installed with a clamping plate 605 through an extension plate 604.

[0028] It should be noted that a number of moving grooves are opened on the plate body of the limiting sealing plate 601, and the number of moving grooves is the same as that of the flipping plates 603. A flipping shaft 6031 is arranged on the plate body of the flipping plate 603. The flipping shaft 6031 is rotatably connected with the flipping frame 602. A swinging seat 6032 is fixedly installed at the upper end of the flipping plate 603. A sliding seat 6033 is rotatably installed at the upper end of the swinging seat 6032. The sliding seats 6033 slide inside the corresponding moving grooves respectively.

[0029] Among them, a mating thread 6034 is arranged on the upper surface of each sliding seat 6033. A control thread 6061 is arranged at the bottom of the activity turntable 606. The control thread 6061 is in threaded cooperation with a number of mating threads 6034. An extension sleeve 6062 is arranged on the lower surface of the activity turntable 606. A second knob 6063 is fixedly installed at the bottom of the extension sleeve 6062.

[0030] By rotating the second knob 6063, the movable turntable 606 can be driven to rotate. When the movable turntable 606 rotates, the control thread 6061 on the lower surface of the movable turntable 606 will be in thread fit with a number of mating threads 6034, and the limiting fit between the sliding seat 6033 and the moving groove is utilized, so that each sliding seat 6033 moves synchronously in position. In order to realize the clamping operation of multiple clamping plates 605, through the synchronous movement of each sliding seat 6033, the swinging seat 6032 below can be pulled to swing, and then the turning plate 603 can be adjusted in angle by using the turning shaft 6031, so that the clamping plate 605 at the lower end performs the clamping operation. Through the above structure, fast synchronous clamping operation can be carried out, further improving the clamping efficiency, and the clamping plate 605 can also be applied to couplings of different sizes, and the heating plate 6043 can also match the size of the coupling, further improving the application range of the present application.

[0031] When specifically set, the body of the extension plate 604 is provided with a placement groove 6042, and an electric heating plate 6043 for heating is installed inside the placement groove 6042, and cables 6041 are arranged on the outer sides of the electric heating plates 6043; A number of electric brushes 5031 are respectively installed inside the rotating support 503, the electric brushes 5031 are connected to the corresponding cables 6041, and a slip ring 5021 is arranged inside the rotating sleeve 502, and the slip ring 5021 is electrically connected to the electric brushes 5031.

[0032] By arranging a slip ring 5021 inside the rotating sleeve 502, when a number of extension plates 604 rotate, each electric heating plate 6043 is connected to the electric brushes 5031 by cables 6041, so that each electric brush 5031 can be electrically connected to the slip ring 5021 to realize real-time power transmission, so as to ensure that each electric heating plate 6043 can continuously perform heating operation during the rotation process. Through the above structure, the heating range can be freely controlled. Compared with the prior art in which the electric heating coil is sleeved on the outer ring of the coupling, not only the size of the coupling needs to be matched, but also additional implementation steps are required during use. Therefore, the present application can also perform efficient and multi-size heating and disassembly while realizing heating and disassembly, improving the application range of the present application.

[0033] When specifically set, a number of grooves 6051 are opened on the body of the clamping plate 605, and a floating seat 6053 is movably installed inside each groove 6051 through a support spring 6052, and an auxiliary ball 6054 is rotatably installed inside the floating seat 6053.

[0034] When heated, since the clamping plate 605 will approach the coupling in advance, in order to avoid wear between the clamping plate 605 and the coupling, auxiliary balls 6054 are arranged between the clamping plate 605 and the coupling. Then, when rotating, the self-rotation of the auxiliary balls 6054 can reduce the friction therebetween, so as to ensure that the subsequent rotational heating can operate for a long time. And when disassembling later, the support spring 6052 can prevent the auxiliary balls 6054 from being damaged due to extrusion.

[0035] In this embodiment, the driving assembly 4 includes a hollow shaft motor 401. The hollow shaft motor 401 is fixedly installed on the lower surface of the fixing frame 3. A hollow spline shaft 4011 is fixedly installed at the output end of the hollow shaft motor 401. A rotating groove 403 is formed on the upper surface of the rotating support 503. A rotating disk 402 is arranged inside the rotating groove 403. A spline sleeve 4021 is fixedly installed on the upper surface of the rotating disk 402. The spline sleeve 4021 is connected to the hollow spline shaft 4011.

[0036] By starting the hollow shaft motor 401, the hollow spline shaft 4011 can be driven to rotate. Since the hollow spline shaft 4011 is connected to the spline sleeve 4021, the rotating disk 402 can not only rotate continuously, but also adjust the distance between the rotating disk 402 and the hollow shaft motor 401, so that the hollow shaft motor 401 can meet the needs of both the rotation of the rotating disk 402 and the lifting of the rotating disk 402 at the same time.

[0037] In this application, limiting sliding grooves 4023 are formed on both sides inside the rotating disk 402. A moving slide seat 404 is slidably installed inside each limiting sliding groove 4023. A locking insertion rod 4041 is fixedly installed on one side of the moving slide seat 404. A locking slot 5032 is formed on the inner wall of the rotating support 503. The locking slot 5032 and the locking insertion rod 4041 are inserted and matched with each other; An extension platform 4042 is fixedly installed on the upper side of the moving slide seat 404. A combined screw sleeve 4043 is fixedly installed on the outside of the extension platform 4042. The inner wall of the combined screw sleeve 4043 is in threaded cooperation with the threaded top rod 10.

[0038] When it is necessary to rotate the clamping assembly 6 for heating, the moving slide seat 404 is moved to the outside, so that the locking insertion rod 4041 is inserted into the locking slot 5032, so that the current rotating disk 402 is connected to the rotating support 503. Then, under the drive of the hollow shaft motor 401, the lower clamping assembly 6 rotates continuously to realize the rotational heating operation; When it is necessary to disassemble the lifting and clamping assembly 6, the sliding seat 404 is moved to the inside, so that the combined screw sleeves 4043 on both sides are combined together, and the combined screw sleeve 4043 can be threadedly engaged with the threaded ejector rod 10. Thus, driven by the hollow shaft motor 401, the combined screw sleeve 4043 will rotate around the threaded ejector rod 10, and under the threaded engagement of the threaded ejector rod 10, the lifting of the combined screw sleeve 4043 and the lower clamping assembly 6 is realized, and the disassembly operation is achieved.

[0039] Among them, an expansion chute 405 is provided between the limit chutes 4023. An expansion slide rod 4044 is fixedly installed on the outer side of the two moving slide seats 404. A threaded sleeve 4045 is fixedly installed at one end of the expansion slide rod 4044. The expansion slide rod 4044 is slidably installed in the expansion chute 405; A forward and reverse lead screw 4051 is rotatably installed inside the expansion chute 405. The rod body of the forward and reverse 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 forward and reverse lead screw 4051. A first knob 4022 is rotatably installed on the upper side of the expansion chute 405. A first bevel gear 4024 is fixedly installed at the bottom of the first knob 4022. The first bevel gear 4024 is meshed with the second bevel gear 4052.

[0040] In order to realize the switching of the drive of the hollow shaft motor 401, by rotating the first knob 4022 to drive the first bevel gear 4024 to be meshed with the second bevel gear 4052, the forward and reverse lead screw 4051 rotates inside the expansion chute 405. Among them, by using the limit cooperation between the expansion slide rod 4044 and the expansion chute 405, the forward and reverse lead screw 4051 and the threaded sleeves 4045 on both sides are threadedly engaged, and then the position adjustment of the two moving slide seats 404 is realized to achieve the subsequent drive switching.

[0041] The working principle of this coupling disassembly device: When in use, first place the bearing of the coupling to be disassembled in the bearing fixing seat 7. Subsequently, by rotating the second knob 6063, the movable turntable 606 can be driven to rotate. When the movable turntable 606 rotates, the control thread 6061 on the lower surface of the movable turntable 606 is threadedly engaged with a plurality of mating threads 6034, and by using the limit cooperation between the sliding seat 6033 and the moving groove, the position of each sliding seat 6033 is synchronously moved, so that a plurality of clamping plates 605 clamp the coupling at the same time; After that, the sliding seat 404 is moved to the outside, so that the locking plug 4041 is inserted into the locking slot 5032, so that the current rotating disk 402 is connected to the rotating support 503. Then, driven by the hollow shaft motor 401, the lower clamping assembly 6 rotates continuously to realize the rotary heating operation; After the heating is completed, it is moved to the inside by moving the sliding seat 404, so that the combined screw sleeves 4043 on both sides are combined together, and the combined screw sleeve 4043 can be threadedly engaged with the threaded ejector rod 10. Thus, driven by the hollow shaft motor 401, the combined screw sleeve 4043 will rotate around the threaded ejector rod 10, and under the threaded engagement of the threaded ejector rod 10, the lifting of the combined screw sleeve 4043 and the lower clamping assembly 6 is realized. By starting the lifting adjustment, multiple clamping plates 605 are used to quickly pull out the coupling, thereby realizing the disassembly operation.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to enumerate all the embodiments here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
