Technical Field

[0001] This utility model relates to the field of motor assembly technology, and more specifically, to a motor rotor assembly device. Background Technology

[0002] In the process of motor assembly, the stator and rotor assembly is a key step. Since the rotor is usually an asymmetrical structure, the center of gravity needs to be adjusted during the hoisting process. Specifically, the position of the hoisting point is adjusted according to the center of gravity of the rotor.

[0003] In related technologies, the structure that can assist in the adjustment of the center of gravity is a set of components. When adjusting, the bolts must be pulled out first, and the position of the lifting point is changed by pushing the movable part in the set of components. After moving it into place, the alignment of the holes is observed, and then the bolts are tightened. This method is complicated to operate.

[0004] In conclusion, simplifying the operation of adjusting the position of hoisting points is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The locking member is movable relative to the hoisting assembly to engage with the adjustment portion or to move out of the adjustment portion.

[0011] When the locking member moves out of the adjustment part corresponding to the first position, the elastic member is pressed, and the locking member can move with the hoisting assembly until it passes the adjustment part corresponding to the second position. The elastic member resets to allow the locking member to move and lock into the adjustment part. The first position and the second position are arranged adjacent to each other.

[0012] Preferably, the locking member has a mounting cavity, one end of the elastic member is connected to the mounting cavity, and the other end of the elastic member abuts against or is fixed to the hoisting assembly.

[0013] Preferably, a sealing part is provided at one end of the installation cavity opening, the sealing part is fixed to the hoisting assembly and extends towards the center of the hoisting assembly, and the elastic element is connected to the sealing part.

[0014] Preferably, the locking member includes a guide portion and a locking portion connected to the guide portion. The guide portion passes through the hoisting assembly. The outer peripheral dimension of the locking portion is larger than the outer peripheral dimension of the guide portion, and the locking portion can extend into or move out of the adjusting portion.

[0015] Preferably, the hoisting assembly includes a sliding part and a main body connected to the sliding part. The sliding part has a groove that is slidably connected to the connecting arm assembly. The adjusting part and the connecting part are both located within the area space formed by the groove. The main body is movable to drive the sliding part to slide relative to the connecting arm assembly, so that the locking member moves from the first position to the second position.

[0016] Preferably, the slide includes a first part and a second part connected to the first part, the locking member is disposed through the first part, the second part and the connecting arm assembly are slidably connected, and the locking member can engage or disengage with the adjusting part located in the first part when it moves within the first part.

[0017] Preferably, the first part includes a sidewall connected to a limiting wall, the locking member moves in the space formed by the sidewall and the limiting wall, one edge of the limiting wall is flush with the bottom edge of the sidewall, and the other edge of the limiting wall is lower than the bottom edge of the adjusting part and the connecting part;

[0018] The bottom of the groove in the second part includes a fitting portion and a clearance portion connected to the fitting portion and relatively far away from the groove opening. The fitting portion is located on both sides of the clearance portion for fitting the connecting arm assembly.

[0019] Preferably, one side of the connecting arm assembly is a vertical part for connecting the rotor, and the other side of the connecting arm assembly is a horizontal part. The adjusting part and the connecting part are both provided on at least one edge of the horizontal part, and the edge is the edge corresponding to both sides of the horizontal part along its moving direction.

[0020] Preferably, both the adjusting part and the connecting part have an arc-shaped structure, with the arc-shaped structure of one of the adjusting part and the connecting part facing the center of the horizontal part, and the arc-shaped structure of the other part facing away from the center of the horizontal part.

[0021] Preferably, the assembly further includes a combined sleeve, which comprises a fixed sleeve fixed to the connecting arm assembly, multiple adjusting sleeves, and a copper sleeve. The multiple adjusting sleeves have different internal diameters. The outer side of any adjusting sleeve is connected to the fixed sleeve, and the inner side of any adjusting sleeve is connected to the copper sleeve. The copper sleeve is used to house the rotor.

[0022] The motor rotor assembly device provided by this utility model includes a connecting arm assembly, a lifting assembly, and a locking assembly. The locking assembly includes a locking member and an elastic member connected to the locking member. One side of the connecting arm assembly is used to connect the rotor. The lifting assembly can slide relative to the connecting arm assembly to change the lifting point, so that the lifting point and the rotor's center of gravity are on the same straight line. The connecting arm assembly has multiple spaced adjustment parts, and two adjacent adjustment parts are connected by a connecting part. The lifting assembly can be connected to any adjustment part through the locking member to lock the lifting assembly and the connecting arm assembly, so as to perform reliable lifting operations. The locking member can move relative to the lifting assembly to lock onto the adjustment part or move out of the adjustment part. The state in which the locking member is locked into the adjustment part corresponds to the state in which the lifting assembly and the connecting arm assembly are locked. The state in which the locking member moves out of the adjustment part corresponds to the state in which the lifting assembly can slide relative to the connecting arm assembly to perform lifting point position adjustment operations, so that the rotor can be lifted with good balance and stability.

[0023] The first position and the second position are two adjacent positions on the connecting arm assembly. When the locking member moves out of the adjustment part corresponding to the first position, the elastic member is pressed. At this time, the lifting assembly can drive the locking member to slide relative to the connecting arm assembly until the locking member moves to the adjustment part corresponding to the second position. The elastic force generated by the pressing of the elastic member can make the locking member move and lock into the adjustment part corresponding to the second position. At this time, the lifting assembly and the connecting arm assembly are locked, realizing the adjustment operation of the lifting point position of the lifting assembly.

[0024] The beneficial effects of this utility model are as follows: by setting an adjustment part and a connecting part in the connecting arm assembly, the locking part slides with the hoisting assembly to realize the switching between the two adjustment parts corresponding to the first position and the second position. The elastic force of the elastic part connected by the locking part can make the locking part automatically lock into the adjustment part corresponding to the second position to realize the adjustment of the hoisting point of the hoisting assembly. The position of the hoisting point can be flexibly adjusted according to the center of gravity of the rotor, thereby improving the efficiency and accuracy of the adjustment.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] The core of this utility model is to provide a motor rotor assembly device. By setting an adjustment part and a connecting part in the connecting arm assembly, the locking part slides with the hoisting assembly to realize the switching between the two adjustment parts corresponding to the first position and the second position. The elastic force of the elastic element connected by the locking part can make the locking part automatically lock into the adjustment part corresponding to the second position to realize the adjustment of the hoisting point of the hoisting assembly. This simplifies the operation of adjusting the position of the hoisting point, improves the adjustment efficiency, and ensures the balance and stability of the rotor hoisting.

[0039] The motor rotor assembly device provided by this utility model specifically includes a connecting arm assembly 1, a hoisting assembly 2, and a locking assembly. Please refer to the following for details. Figure 1 , Figure 2 .

[0040] One side of the connecting arm assembly 1 is used to connect the rotor. When the lifting assembly 2 is locked to the connecting arm assembly 1, the rotor can be lifted by the lifting assembly 2 for assembly with the stator. Specifically, the lifting assembly 2 can be in the form of a lifting ring. The position of the lifting point of the lifting assembly 2 is adjusted by the position of the rotor's center of gravity to ensure the reliability and effectiveness of rotor lifting.

[0041] On the other side of the connecting arm assembly 1, there are multiple spaced adjustment parts 111, and adjacent adjustment parts 111 are connected by a connecting part 112. The adjustment parts 111 here correspond to different connection positions of the hoisting assembly 2 and the connecting arm assembly 1, that is, the hoisting points of the hoisting assembly 2, so that the hoisting points can be adjusted according to the actual center of gravity position of the rotor to ensure the balance when hoisting the rotor and to ensure that the rotor and stator can be reliably and accurately connected and assembled.

[0042] The specific form of the connecting part 112 and the adjusting part 111 is not limited. For example, the adjusting part 111 can be a circular hole, an arc-shaped hole, a square hole, etc., and the connecting part 112 can be an arc-shaped plane, a directional plane, etc.

[0043] The lifting assembly 2 is slidably connected to the connecting arm assembly 1, that is, the lifting assembly 2 can slide relative to the connecting arm assembly 1, specifically, at least one of them can slide, so as to adjust the connection position of the lifting assembly 2 and the connecting arm assembly 1. The lifting assembly 2 can be connected to any adjusting part 111 through the locking assembly to achieve locking of the lifting assembly 2 and the connecting arm assembly 1.

[0044] The lifting assembly 2 can slide relative to the connecting arm assembly 1 in the direction formed by the connection between the adjusting part 111 and the connecting part 112.

[0045] The locking assembly specifically includes a locking member 3 and an elastic member connected to the locking member 3. The hoisting assembly 2 is connected to any adjusting part 111 through the locking member 3. Specifically, the locking member 3 can be locked in the adjusting part 111 to achieve locking between the hoisting assembly 2 and the connecting arm assembly 1.

[0046] The locking member 3 can move relative to the hoisting assembly 2 to lock onto the adjusting part 111 or move out of the adjusting part 111. The direction of movement of the locking member 3 is different from the direction of sliding of the hoisting assembly 2. For example, if the direction of sliding of the hoisting assembly 2 is left and right, then the direction of movement of the locking member 3 is up and down.

[0047] When the locking member 3 moves out of the adjustment part 111 corresponding to the first position, the elastic member 5 is pressed. At this time, the locking between the hoisting assembly 2 and the connecting arm assembly 1 is released, and the hoisting assembly 2 can slide along the connecting arm assembly 1 to adjust the position of the hoisting point. The movement of the hoisting assembly 2 drives the locking member 3 to move. When the locking member 3 moves past the connecting part 112, the elastic member 5 can remain pressed until the locking member 3 passes the adjustment part 111 corresponding to the second position. At this time, the elastic member 5 resets so that the locking member 3 moves and locks into the adjustment part 111. The hoisting assembly 2 and the connecting arm assembly 1 are locked, and one hoisting point position adjustment operation is completed.

[0048] It should be noted that the first position and the second position mentioned above are two adjacent positions on the connecting arm assembly 1.

[0049] Furthermore, when the locking member 3 moves out of the adjustment part 111 corresponding to the first position, it corresponds to manually pressing the locking member 3, such as... Figure 7 As shown, the locking member 3 can be released from the adjusting part 111, thus unlocking the hoisting assembly 2 and the connecting arm assembly 1; and when the locking member 3 reaches the adjusting part 111 corresponding to the second position, releasing the locking member 3 allows it to be locked into the adjusting part 111 under the action of elastic force, as shown. Figure 6 As shown, this allows for the locking of the lifting assembly 2 and the connecting arm assembly 1. If the requirements are still not met after one adjustment of the lifting point position, the above process can be repeated.

[0050] In this embodiment, one end of the elastic element 5 can be connected to the locking element 3, and the other end can be fixed to or abut against the hoisting assembly 2 and the connecting arm assembly 1. When the elastic element 5 is compressed, it is relative to the hoisting assembly 2 or the connecting arm assembly 1. Here, the hoisting assembly 2 or the connecting arm assembly 1 actually provides the force point when the elastic element 5 is compressed.

[0051] In this embodiment, the locking and unlocking between the hoisting assembly 2 and the connecting arm assembly 1 can be achieved by moving the locking member 3. When in the unlocked state, the hoisting assembly 2 can drive the locking member 3 to move, so that the locking member 3 changes from being locked in the adjustment part 111 corresponding to the first position to being locked in the adjustment part 111 corresponding to the second position. The locking member 3 can be quickly reset and enter the adjustment part 111 by the elastic force generated by the elastic member 5. The adjustment of the hoisting point position of the hoisting assembly 2 is simple and accurate, improving the efficiency of the adjustment.

[0052] In this embodiment, the pressing and releasing operation of the locking member 3 is simple and can be used without professional personnel, thus improving the practicality of the assembly device.

[0053] Based on the above embodiments, please refer to Figure 6 The locking member 3 is provided with an installation cavity 321. One end of the elastic member 5 is connected to the installation cavity 321, and the other end of the elastic member 5 is abutted or fixed to the hoisting assembly 2.

[0054] The mounting cavity 321 corresponding to the locking member 3 is specifically an opening groove on the locking member 3, and the specific size and shape of the opening are not limited. Part of the elastic member 5 is located inside the mounting cavity 321, while the other part extends out of the mounting cavity 321 and abuts or is fixed to the lifting assembly 2.

[0055] By setting the mounting cavity 321, the movement of the elastic element 5 can be limited to a certain extent, which can reliably fix and protect the elastic element 5.

[0056] In one embodiment, the elastic element 5 is fixed to the hoisting assembly 2. By fixing both ends of the elastic element 5, the elastic element 5 can be pressed or reset with good stability and reliability, ensuring the reliable and effective adjustment of the hoisting point position.

[0057] In another embodiment, the elastic member 5 abuts against the hoisting assembly 2. In this case, an abutment groove can be provided at the abutment position of the hoisting assembly 2 so that the elastic member 5 can extend into the abutment groove, thereby limiting the elastic member 5 and preventing the abutment position of the elastic member 5 from shifting and affecting the operation of adjusting the position of the hoisting point.

[0058] Based on any of the above embodiments, please refer to Figure 6 One end of the opening of the mounting cavity 321 is provided with a sealing part 23. The sealing part 23 is fixed to the hoisting component 2 and extends towards the center of the hoisting component 2. The elastic element 5 is connected to the sealing part 23.

[0059] There is a safe distance between the sealing part 23 and the opening of the mounting cavity 321, specifically, a space that allows the elastic element 5 to deform, so as to avoid the mounting cavity 321 and the sealing part 23 from colliding and to ensure the safety and reliability of the adjustment.

[0060] The sealing part 23 is fixed to the hoisting assembly 2 and extends towards the center of the hoisting assembly 2. The hoisting assembly 2 is specifically connected to the elastic element 5 through the sealing part 23. The sealing part 23 can be integrally formed with the hoisting assembly 2.

[0061] The length of the sealing part 23 extending towards the center of the hoisting assembly 2 needs to be considered to avoid interfering with the connecting arm assembly 1 and not affect the sliding of the hoisting assembly 2 along the connecting arm assembly 1. The specific extension length can be flexibly set according to the actual situation.

[0062] It should be noted that when the elastic element 5 is compressed, the mounting cavity 321 is located close to the sealing part 23. At this time, the locking element 3 can be moved out from the adjustment part 111. Furthermore, the locking element 3 is slid by the hoisting assembly 2, the elastic element 5 remains in a compressed state and passes through the connecting part 112 adjacent to this adjustment part 111. Then the locking element 3 passes through another adjustment part 111 adjacent to this adjustment part 111. The elastic element 5 connected to the locking element 3 automatically resets. The corresponding locking element 3 can pass through the hoisting assembly 2 and be locked in another adjustment part 111. Therefore, the efficiency of adjusting the hoisting point position of the hoisting assembly 2 can be effectively improved.

[0063] Based on any of the above embodiments, please refer to Figure 5 , Figure 6 , Figure 7 The locking component 3 includes a guide portion 31 and a locking portion 32 connected to the guide portion 31. The guide portion 31 passes through the lifting assembly 2 and provides guidance for the movement of the locking component 3 via the lifting assembly 2. It should be noted that a limiting portion is provided at the end of the guide portion 31 away from the locking portion 32 to prevent the locking component 3 from passing through the lifting assembly 2, and the limiting portion provides a point of force for manual pressing of the locking component 3.

[0064] The hoisting assembly 2 is provided with a mounting hole 222. The outer circumference of the locking part 32 is larger than that of the guide part 31, specifically, the outer circumference of the locking part 32 is larger than the diameter of the mounting hole 222. When adjusting the position of the hoisting point, the locking part 32 can extend into or move out of the adjustment part 111. During this process, the movement of the locking part 32 is always within the slide groove 221 of the hoisting assembly 2. When the locking part 32 and the bottom of the slide groove 221 are in contact, the corresponding locking member 3 locks the hoisting assembly 2 and the connecting arm assembly 1. When the locking part 32 moves away from the bottom of the slide groove 221, the corresponding hoisting assembly 2 and the connecting arm assembly 1 are unlocked.

[0065] Based on any of the above embodiments, please refer to Figure 6 , Figure 7 , Figure 8The hoisting assembly 2 includes a sliding part 22 and a main body part 21 connected to the sliding part 22. The main body part 21 may be provided with a hanging ring or other part for easy hoisting.

[0066] The sliding part 22 has a groove 221 that is slidably connected to the connecting arm assembly 1. The adjusting part 111 and the connecting part 112 are both located in the area space formed by the groove 221. The area space here refers to the space formed by the groove wall of the groove 221.

[0067] The main body 21 is movable to drive the sliding part 22 to slide relative to the connecting arm assembly 1, so that the locking member 3 moves from the first position to the second position. By sliding the sliding part 22, the locking member 3 can move accordingly to reach the position of either the connecting part 112 or the adjusting part 111, thereby improving the range and flexibility of the lifting point position adjustment, ensuring the balance and stability of the lifting rotor, and ensuring reliable docking of the rotor and stator.

[0068] Based on any of the above embodiments, please refer to Figure 5 The slide 221 includes a first part 2211 and a second part 2212 connected to the first part 2211. The locking member 3 is set through the first part 2211. Specifically, the guide part 31 of the locking member 3 is set through the mounting hole 222 and the first part 2211. When the locking member 3 is pressed down, the lifting assembly 2 and the connecting arm assembly 1 are unlocked; or the locking part 32 is set through the first part 2211. When the locking member 3 is released, the lifting assembly 2 and the connecting arm assembly 1 are locked.

[0069] The second part 2212 is slidably connected to the connecting arm assembly 1. Specifically, the side wall of the second part 2212 is provided with a slot, which can wrap around a part of the connecting arm assembly 1 to ensure the reliability of the sliding of the hoisting assembly 2 relative to the connecting arm assembly 1 and avoid the separation of the two.

[0070] When the locking member 3 moves within the first part 2211, it can engage or disengage with the adjusting part 111 located within the first part 2211. Due to the slidable arrangement of the hoisting assembly 2, the adjusting part 111 located within the first part 2211 can be any adjusting part 111. During the above process, the movement of the locking member 3 is based on manual pressing or automatic movement to reset by the elastic force generated by the pressing of the elastic member 5.

[0071] Based on any of the above embodiments, please refer to Figure 5 , Figure 1The first part 2211 includes a side wall 22111, which is connected to a limiting wall 24. The locking member 3 moves in the space formed by the side wall 22111 and the limiting wall 24. The guide part 31 ensures that the movement of the locking member 3 has good accuracy, avoiding positional deviation that could affect the adjustment effect of the lifting point position and the reliable locking of the lifting assembly 2 and the connecting arm assembly 1. One edge of the limiting wall 24 is flush with the bottom edge of the side wall 22111, and the other edge of the limiting wall 24 is lower than the bottom edge of the adjusting part 111 and the connecting part 112 to avoid interference with the connecting arm assembly 1 and ensure the reliability of the relative sliding between the connecting arm assembly 1 and the lifting assembly 2.

[0072] The bottom of the groove in the second part 2212 includes a fitting portion 22122 and a clearance portion 22121 connected to the fitting portion 22122 and located relatively away from the opening of the slide groove 221. The fitting portion 22122 is located on both sides of the clearance portion 22121 for fitting the connecting arm assembly 1. The clearance portion 22121 does not contact the connecting arm assembly 1; only the fitting portions 22122 on both sides fit the connecting arm assembly 1. By reducing the contact area between the slide groove 221 and the connecting arm assembly 1, the sliding resistance is reduced, thereby improving the smoothness and reliability of the sliding of the lifting assembly 2 relative to the connecting arm assembly 1.

[0073] Based on any of the above embodiments, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 One side of the connecting arm assembly 1 is a vertical part 12 for connecting the rotor, and the other side is a horizontal part 11 for connecting the lifting assembly 2. The connecting arm assembly 1 is designed as an L-shaped structure, which is simple, reliable, low in manufacturing cost, and easy to maintain. The material of the L-shaped structure should have sufficient strength and rigidity to ensure safety during the lifting process.

[0074] The adjusting part 111 and the connecting part 112 are both provided on at least one edge of the horizontal part 11. The edge is the edge corresponding to both sides of the horizontal part 11 along its moving direction. The adjusting part 111 and the connecting part 112 can be provided on one side or both sides. If both sides are provided, when adjusting the position of the hoisting point, the corresponding locking parts 3 on both sides must move. Specifically, the locking parts 3 on both sides can be connected by a connecting rod. By pressing or releasing the connecting rod, the locking parts 3 on both sides can be moved synchronously at the same time.

[0075] A handrail 121 is also provided on the vertical part 12 to facilitate personnel to accurately control the assembly process of the rotor.

[0076] Based on any of the above embodiments, please refer to Figure 4Both the adjusting part 111 and the connecting part 112 have arc-shaped structures. The arc-shaped structure of one of the adjusting part 111 and the connecting part 112 is arranged towards the center of the horizontal part 11, while the arc-shaped structure of the other is arranged away from the center of the horizontal part 11.

[0077] The arc-shaped structure corresponding to the connecting part 112 is a closed shape, and the arc-shaped structure corresponding to the adjusting part 111 is an arc-shaped hole. Multiple adjusting parts 111 and multiple connecting parts 112 are connected to form a wave-shaped structure. The wave-shaped structure is arranged in the length direction of the horizontal part 11 to increase the adjustable range of the hoisting point.

[0078] The locking member 3 can enter the arc-shaped structure corresponding to any adjustment part 111 to adjust the position of the lifting point. With the setting of this arc-shaped structure, the locking member 3 can move within the space formed by the arc-shaped structure corresponding to the adjustment part 111 and the side wall 22111 to lock the adjustment part 111 or move out of the adjustment part 111.

[0079] In this embodiment, after the locking member 3 is released, under the action of the elastic force of the elastic member 5 being pressed, the locking member 3 automatically resets and enters the arc structure to lock the adjusting part 111, thereby locking the hoisting assembly 2 and the connecting arm assembly 1, preventing the lifting ring from slipping during the assembly process, and improving the stability and safety of the device.

[0080] Based on any of the above embodiments, please refer to Figure 2 , Figure 9 It also includes a combined sleeve 4 connected to the vertical part 12. The combined sleeve 4 includes a fixed sleeve 42 fixed to the connecting arm assembly 1, a plurality of adjusting sleeves 43, and a copper sleeve 44. The plurality of adjusting sleeves 43 have different internal diameters. The outer side of any adjusting sleeve 43 is connected to the fixed sleeve 42, and the inner side of any adjusting sleeve 43 is connected to the copper sleeve 44. The copper sleeve 44 is used to place the rotor.

[0081] Multiple adjusting cylinders 43 correspond to different internal diameters, so as to be applicable to a variety of rotors of different specifications and improve the versatility of the assembly device.

[0082] By installing the copper sleeve 44, it can be ensured that the rotor will not slip or fall off during hoisting, while protecting the rotor shaft extension from bumps and scratches.

[0083] In addition, please refer to Figure 9 Multiple limiting screws 41 are provided along the axial direction of the fixed cylinder 42, and the limiting screws 41 pass through the fixed cylinder 42 and any adjusting cylinder 43.

[0084] After determining the adjusting cylinder 43 by the rotor shaft extension diameter, the fixing cylinder 42 and the adjusting cylinder 43 are reliably fixed by multiple limiting screws 41. Then, the copper sleeve 44 is fixed inside the adjusting cylinder 43. The inner diameter of the copper sleeve is 3-5mm larger than the outer diameter of the rotor to facilitate the insertion of the rotor and prevent damage to the rotor journal.

[0085] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0086] The present invention provides a detailed description of a motor rotor assembly device.
