Description

Technical Field

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

[0002] A coupling, also known as a joint, is a mechanical component used to securely connect the driving and driven shafts of different mechanisms, enabling them to rotate together and transmit motion and torque. When the bearings on the input and output shafts of a motor connected to the coupling need to be replaced, the coupling must be removed before the bearings can be replaced.

[0003] To facilitate the removal of couplings located far from the motor bearing end, coupling removal devices in related technologies often use screws connected to the coupling. This results in a relatively large coupling removal device, making it difficult to store and fold up when not in use. Utility Model Content

[0004] The purpose of this utility model is to provide a coupling disassembly device, which has a simple structure and is easy to store.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A coupling disassembly device is provided, comprising a support member, a jack connecting assembly, and two connecting screw rods. The jack connecting assembly is disposed on the symmetrical center line of the support member and is used to connect with a jack. The support member has a first fixing surface and a second fixing surface arranged in parallel at intervals. The coupling disassembly device also includes multiple fixing components, some of which are disposed on the first fixing surface and others on the second fixing surface. The coupling disassembly device has a working state and a stored state. When the coupling disassembly device is in the working state, one end of the connecting screw rod is detachably connected to the support member, and the other end of the connecting screw rod is used to connect with the coupling to be disassembled. The length direction of the connecting screw rod is perpendicular to the length direction of the support member, and the distance between the two connecting screw rods and the jack connecting assembly is equal. When the coupling disassembly device is in the stored state, the two connecting screw rods are fixed to the first fixing surface and the second fixing surface respectively by the fixing components.

[0007] Preferably, the fixing component includes a rotating shaft, a locking element, and two semi-circular locking rings. One end of the two semi-circular locking rings is rotatably connected by the rotating shaft, and the other end of the two semi-circular locking rings is locked or unlocked by the locking element. The two semi-circular locking rings can hold the connecting screw tightly.

[0008] Preferably, the inner walls of both semicircular locking rings are threaded, and the connecting screw is screwed to the fixing assembly.

[0009] Preferably, when the coupling disassembly device is in use, both connecting screws are slidably connected to the support.

[0010] Preferably, the support member is provided with a sliding groove along the length direction of the support member, and the coupling disassembly device further includes two adjusting blocks, both of which are slidably connected to the sliding groove, and two connecting screws are screwed to the two adjusting blocks one-to-one.

[0011] Preferably, the end of the connecting screw away from the support is provided with a fixing screw hole, which extends axially along the connecting screw. The coupling disassembly device also includes a limiting member, which is screwed into the fixing screw hole.

[0012] Preferably, the jack connection assembly includes two arc-shaped fixing blocks and two adjusting screws. The arc-shaped fixing blocks are located on both sides of the slide groove and are fixedly connected to the support. Each of the two arc-shaped fixing blocks is provided with a threaded through hole. The axes of the two threaded through holes coincide, and the axial direction of the two threaded through holes is perpendicular to the length direction of the slide groove. The two adjusting screws are screwed through the two threaded through holes one to one. A clamping block is provided at the end of the adjusting screw near the slide groove, and a handle is provided at the end of the adjusting screw away from the slide groove.

[0013] Preferably, the clamp is detachably connected to the adjusting screw.

[0014] Preferably, the clamping block has an arc-shaped contact surface on the side near the slide groove, which is used to abut against the jack.

[0015] Preferably, an anti-slip layer is provided on the contact surface.

[0016] The beneficial effects of this utility model are as follows: It provides a coupling disassembly device, which sets multiple fixing components on the first and second fixing surfaces of the support member.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] Please refer to Figures 1 to 6 This embodiment provides a coupling disassembly device, which includes a support member 1, a jack connecting assembly 2, and two connecting screws 3. The jack connecting assembly 2 is disposed on the symmetrical center line of the support member 1 and is used to connect with a jack. The support member 1 has a first fixing surface 11 and a second fixing surface 12 arranged in parallel at intervals. The coupling disassembly device also includes multiple fixing components 4, some of which are disposed on the first fixing surface 11 and others on the second fixing surface 12. The coupling disassembly device has a working state and a storage state. When the coupling disassembly device is in the working state, one end of the connecting screw 3 is detachably connected to the support member 1, and the other end of the connecting screw 3 is used to connect with the coupling to be disassembled. The length direction of the connecting screw 3 is perpendicular to the length direction of the support member 1, and the distance between the two connecting screws 3 and the jack connecting assembly 2 is equal. When the coupling disassembly device is in the storage state, the two connecting screws 3 are fixed to the first fixing surface 11 and the second fixing surface 12 respectively by the fixing components 4. With this configuration, the coupling disassembly device has multiple fixing components 4 on the first fixing surface 11 and the second fixing surface 12 of the support member 1. When the coupling disassembly device is not in use, the two connecting screws 3 can be fixed to the first fixing surface 11 and the second fixing surface 12 respectively through the fixing components 4, so that the coupling disassembly device is in a storage state, reducing the space occupied by the coupling disassembly device and making it easy to store.

[0033] Specifically, the coupling disassembly device is used to disassemble the coupling of the motor input shaft or output shaft.

[0034] Please refer to Figure 1 When the coupling disassembly device is in use, one end of the connecting screw 3 is detachably connected to the support 1, and the other end of the connecting screw 3 is used to connect to the coupling to be disassembled. The length direction of the connecting screw 3 is perpendicular to the length direction of the support 1. By connecting the support 1 and the coupling to be disassembled through the connecting screw 3, the problem that the coupling disassembly device cannot connect to the coupling to be disassembled when the distance between the coupling and the end of the motor bearing is long is avoided, thus preventing its use.

[0035] Alternatively, please refer to Figure 2 and Figure 3 The fixing component 4 includes a rotating shaft 41, a locking element 42, and two semi-circular locking rings 43. One end of each semi-circular locking ring 43 is rotatably connected to the rotating shaft 41, and the other end is locked or unlocked by the locking element 42. The two semi-circular locking rings 43 can grip the connecting screw 3. Specifically, the locking element 42 includes a groove in one of the semi-circular locking rings 43 and a locking block in the other semi-circular locking ring 43. The locking block can engage with the groove to lock the relative position of the two semi-circular locking rings 43, thereby allowing the two semi-circular locking rings 43 to grip the connecting screw 3. With this configuration, when the coupling disassembly device is in the storage state, it is convenient to fix the two connecting screws 3 to the first fixing surface 11 and the second fixing surface 12, thereby reducing the space occupied by the coupling disassembly device and facilitating storage.

[0036] Alternatively, please refer to Figure 3 Both semi-circular locking rings 43 have threads on their inner walls, and the connecting screw 3 is screwed to the fixing component 4. This design further enhances the reliability of the fixing component 4 and prevents the connecting screw 3 from slipping out of the fixing component 4 when it is stored.

[0037] Alternatively, please refer to Figure 1 When the coupling disassembly device is in use, both connecting screws 3 are slidably connected to the support member 1. This configuration allows the coupling disassembly device to adjust the distance between the two connecting screws 3 according to the size of the coupling to be disassembled, improving the versatility of the device.

[0038] Specifically, a groove 13 is provided on the support member 1 along its length. The coupling disassembly device also includes two adjusting blocks 5, both of which are slidably connected to the groove 13. Two connecting screws 3 are screwed onto the two adjusting blocks 5 in a corresponding manner. Each adjusting block 5 has a sliding block and a limiting block. The sliding block is slidably connected in the groove 13, and the limiting block abuts against the side wall of the support member 1 away from the screw. The sliding block and the limiting block are arranged perpendicularly, so that the adjusting block 5 is in a "T" shape. This arrangement allows the position of the connecting screw 3 to be flexibly adjusted according to the specific size and installation position of the coupling. The adjusting block 5 is screwed onto the connecting screw 3, which is simple in structure and facilitates the assembly and disassembly of the coupling disassembly device. Operators do not need complicated tools or cumbersome steps; they only need to screw the connecting screw 3 onto the adjusting block 5 and then slide the adjusting block 5 to the appropriate position, thus improving work efficiency.

[0039] Alternatively, please refer to Figure 1 and Figure 4 The connecting screw 3 is provided with a fixing screw hole 31 at the end away from the support member 1. The fixing screw hole 31 extends along the axial direction of the connecting screw 3. The coupling disassembly device also includes a limiting member 6, which is screwed into the fixing screw hole 31.

[0040] Specifically, the limiting member 6 includes a connecting part 61 and a limiting part 62. The coupling to be disassembled is provided with two fixing holes. When using the coupling disassembly device, the sliding adjusting block 5 is slidable so that the distance between the two connecting screws 3 is equal to the distance between the two fixing holes of the coupling to be disassembled. The connecting screws 3 are passed through the fixing holes, and the connecting part 61 of the limiting member 6 is screwed into the fixing screw hole 31 of the connecting screw 3, further ensuring the reliable connection between the coupling disassembly device and the coupling to be disassembled.

[0041] Preferably, please refer to Figure 4 The limiting part 62 of the limiting part 6 is provided with an internal hexagonal hole 621, which makes it easy to rotate the limiting part 62 with an internal hexagonal wrench, and makes it easy to screw the connecting part 61 into the interior of the fixing screw hole 31, thereby improving the installation efficiency of the coupling disassembly device.

[0042] Alternatively, please refer to Figure 5The jack connecting assembly 2 includes two arc-shaped fixing blocks 21 and two adjusting screws 22. The arc-shaped fixing blocks 21 are located on both sides of the slide groove 13 and are fixedly connected to the support member 1. Each of the two arc-shaped fixing blocks 21 has a threaded through hole, the axes of which coincide and are perpendicular to the length direction of the slide groove 13. The two adjusting screws 22 are screwed through the two threaded through holes one-to-one. A clamping block 23 is provided at the end of the adjusting screw 22 near the slide groove 13, and a handle 24 is provided at the end of the adjusting screw 22 away from the slide groove 13. This configuration allows the distance between the two clamping blocks 23 to be adjusted according to the diameter of the jack by turning the adjusting screws 22. The coupling disassembly device is suitable for jacks of different specifications, further improving the device's versatility. The handle 24 facilitates turning the adjusting screws 22, improving the working efficiency of the coupling disassembly device.

[0043] Optionally, the clamping block 23 is detachably connected to the adjusting screw 22. This configuration makes the connection between the clamping block 23 and the adjusting screw 22 simple and detachable, allowing operators to easily inspect the wear of the clamping block 23 and the tightness of the adjusting screw 22. This helps to promptly identify potential safety hazards and ensures that the coupling disassembly device is always in good working condition.

[0044] Alternatively, please refer to Figure 5 and Figure 6 The clamping block 23 has an arc-shaped contact surface on the side near the slide groove 13, which is used to abut against the jack. With this configuration, the arc-shaped contact surface of the clamping block 23 can fit against the arc-shaped outer circumference of the jack, thereby providing a larger contact area and a better clamping effect, thus improving the problem of slippage or loosening caused by shape mismatch and improving the reliability of the coupling disassembly device.

[0045] Alternatively, please refer to Figure 6 An anti-slip layer 231 is provided on the contact surface. This design increases the coefficient of friction between the clamping block 23 and the outer peripheral surface of the jack, effectively preventing the jack from slipping under clamping conditions. Even when the jack is subjected to a large lifting force, the anti-slip layer 231 ensures that the relative position between the jack connecting assembly 2 and the jack remains stable and will not shift due to external forces. This prevents the coupling disassembly device from slipping off during use and improves the reliability of the coupling disassembly device. Specifically, the anti-slip layer 231 is made of rubber material. In other embodiments, the anti-slip layer 231 can also be made of nylon, plastic, or other materials.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
