Some technical terms appearing in the embodiments of this application are explained below.

[0040] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0041] like Figures 1 to 11As shown in the figure, this application provides a motor rotor assembly device, which is applicable to motors. The motor includes a main housing, a stator and a rotor. The stator is pre-installed in the main housing. The motor rotor assembly device is used to assemble the rotor to the center position of the stator in the main housing.

[0042] The motor rotor assembly device includes a first assembly component 1 and a second assembly component 2, which are arranged opposite to each other and located on both sides of the rotor length direction.

[0043] like Figure 2 As shown, the first assembly component 1 includes a guide plate 11 and a guide rod 12. The guide plate 11 is used to connect to one side of the main housing of the motor, and the guide rod 12 is movably inserted through the guide plate 11. The guide rod 12 is used to connect to the first end of the rotor of the motor.

[0044] like Figure 3 As shown, the second assembly component 2 includes a mounting base 21 and an adjusting member 22. The mounting base 21 is used to connect to the side of the main housing away from the guide plate 11. The adjusting member 22 is movably inserted through the mounting base 21 and is used to connect to the second end of the rotor. The adjusting member 22 can move along its own axial direction to drive the rotor to move.

[0045] The first and second ends of the rotor are two ends spaced apart along the length of the rotor.

[0046] The guide disc 11 is disc-shaped or plate-shaped, and its shape can be circular, rectangular, elliptical, or other polygonal, for example... Figure 4 As shown, the guide plate 11 is in the shape of a disc.

[0047] The guide plate 11 is detachably installed on one side of the main housing. For example, the guide plate 11 is connected to the main housing by bolts or other threaded fasteners, which makes it convenient to disassemble the guide plate 11 after the rotor is assembled.

[0048] like Figure 4 As shown, the guide disk 11 has multiple fixing holes 112, which penetrate the guide disk 11 along its thickness direction, and are spaced apart circumferentially along the guide disk 11. The fixing holes 112 are used to insert threaded fasteners, which are used to connect the guide disk 11 to the main housing.

[0049] During the assembly of the rotor, the length direction of the rotor is parallel to the horizontal direction, and the guide plate 11 is provided with a first upward direction mark 113 to facilitate the positioning of the guide plate 11.

[0050] Optionally, the guide plate 11 is provided with a clearance groove 114 to avoid other components in the motor and increase the visibility range. For example... Figure 4As shown, the clearance groove 114 extends through the guide disk 11 along the thickness direction of the guide disk 11, and the clearance groove 114 is arc-shaped.

[0051] The guide rod 12 is rod-shaped or columnar, and the guide disc 11 has a through hole through which the guide rod 12 passes and can move linearly along its own axis within the through hole. The diameter of the through hole is the same as or slightly larger than the outer diameter of the guide rod 12, thereby restricting the movement of the guide rod 12 in the direction perpendicular to its own axis, so that the guide rod 12 moves linearly within the through hole.

[0052] like Figure 5 As shown, one end of the guide rod 12 is provided with a step 121 to adapt to the shape of the rotor end, which facilitates connection with the rotor and positioning and guiding the rotor. The other end of the guide rod 12 is provided with a handle 122 for easy hand operation by the operator.

[0053] Mounting base 21 is disc-shaped or plate-shaped, and its shape can be circular, rectangular, elliptical, or other polygonal, for example... Figure 8 As shown, the mounting base 21 is disc-shaped.

[0054] Mounting base 21 is detachably mounted on the side of the main housing opposite to the first assembly component 1. For example, mounting base 21 is connected to the main housing by threaded fasteners such as bolts and screws, which facilitates the disassembly of mounting base 21 after the rotor is assembled.

[0055] The mounting base 21 has multiple mounting holes 211, which penetrate the mounting base 21 along its thickness direction, and are spaced apart circumferentially along the mounting base 21. For example... Figure 8 As shown, there are twelve mounting holes 211. The mounting holes 211 are used to insert threaded fasteners to connect the mounting base 21 to the main housing, while also facilitating quick disassembly.

[0056] For example, the mounting base 21, guide plate 11, guide rod 12 and adjusting member 22 are coaxially arranged, and the mounting base 21 and guide plate 11 are arranged opposite each other on both sides of the main housing.

[0057] Optionally, the mounting base 21 is provided with a second upward direction mark 212 to facilitate the operator in positioning the mounting base 21.

[0058] For example, such as Figure 9 As shown, the adjusting member 22 is rod-shaped or column-shaped, and the mounting base 21 has a through hole. The adjusting member 22 passes through the through hole and can move linearly along its own axis within the through hole. The diameter of the through hole is the same as or slightly larger than the outer diameter of the adjusting member 22, thereby restricting the movement of the adjusting member 22 in the direction perpendicular to its own axis, so that the adjusting member 22 moves linearly within the through hole.

[0059] The adjusting component 22 is directly or indirectly connected to the second end of the rotor. Since the guide rod 12 is limited to move in a direction perpendicular to the axial direction by the guide plate 11, and the adjusting component 22 is limited to move in a direction perpendicular to the axial direction by the mounting base 21, the linear movement of the adjusting component 22 can drive the rotor to generate linear movement, assembling the rotor in the direction of the first assembly component 1. During this process, both the adjusting component 22 and the guide rod 12 can limit the rotor, avoiding the influence of the rotor's positioning and assembly on the attractive or repulsive forces between the rotor and the stator, preventing collision damage to other components, improving the rotor's assembly efficiency, and enhancing the reliability of the motor assembly.

[0060] Furthermore, since both the adjusting component 22 and the guide rod 12 can limit the rotor, and the operator can operate on the side of the adjusting component 22 and the guide rod 12 away from the rotor, the probability of the operator being hit or squeezed by the rotor and other parts can be reduced, thus improving the safety of the motor assembly process.

[0061] The motor rotor assembly device provided in this application connects the guide rod 12 to the first end of the motor rotor and the adjusting member 22 to the second end of the rotor. The guide rod 12 can be used to position the rotor, and the linear motion of the adjusting member 22 along its own axis can drive the rotor to move, so that the rotor is assembled along its own axis. This prevents the force between the stator and the rotor from affecting the positioning and assembly of the rotor, which helps to improve the assembly efficiency of the motor rotor, prevents collision damage between parts, and improves the safety of the motor assembly process.

[0062] In one specific embodiment, the adjusting member 22 is threadedly connected to the mounting base 21.

[0063] like Figure 9 As shown, the adjusting component 22 includes a rod head 221, a rod body 222, and a hexagonal head 223 connected in sequence. The rod head 221 is used to connect to the second end of the rotor, the rod body 222 is inserted into the mounting base 21, and the hexagonal head 223 is used to adapt to installation tools such as hexagonal sockets and internal hexagonal wrenches.

[0064] The adjusting member 22 has an external thread (not shown in the figure) on its rod body 222, and the mounting base 21 has an internal thread that matches the external thread in its through hole. The adjusting member 22 and the mounting base 21 are connected by the cooperation of the external thread and the internal thread.

[0065] On the one hand, by setting the adjusting component 22 and the mounting base 21 to be threadedly connected, the stable connection between the adjusting component 22 and the mounting base 21 can be ensured. At the same time, the adjusting component 22 can achieve linear movement along its own axis by screwing in the thread, ensuring the smooth assembly of the rotor. On the other hand, the threaded connection between the adjusting component 22 and the mounting base 21 also plays a role in preventing reverse movement. During the process of driving the rotor to move towards the side where the first assembly component 1 is located, the rotor cannot generate reverse movement due to the mutual repulsion between the stator and the rotor.

[0066] Optionally, such as Figure 8 As shown, at least one side surface of the mounting base 21 is provided with a first boss 213. The first boss 213 is a hollow annular cylinder. The inner diameter of the first boss 213 is equal to or slightly larger than the outer diameter of the rod body 222. The rod body 222 is coaxially inserted through the first boss 213.

[0067] By setting the first boss 213, the movement of the adjusting member 22 in the direction perpendicular to its own axis is restricted, so that the adjusting member 22 moves linearly in the through hole, avoiding deviation or skew.

[0068] Optionally, the inner wall of the first boss 213 is flush with the inner wall of the through hole of the mounting base 21. The inner wall of the first boss 213 is provided with an internal thread, which increases the thread length between the adjusting member 22 and the mounting base 21, which is beneficial to improving the connection stability and reliability between the adjusting member 22 and the mounting base 21.

[0069] In a specific embodiment, such as Figure 4 As shown, a limiting sleeve 111 is protruding on one side surface of the guide plate 11, and the guide rod 12 is inserted into the limiting sleeve 111. The guide rod 12 and the limiting sleeve 111 are coaxially arranged so that the guide rod 12 can move along its own axial direction.

[0070] In this embodiment, the limiting sleeve 111 is located on the side of the guide plate 11 away from the second assembly component 2. The limiting sleeve 111 is perpendicular to the surface of the guide plate 11. The inner diameter of the limiting sleeve 111 is equal to or slightly larger than the outer diameter of the guide rod 12.

[0071] The limiting sleeve 111 serves to guide and limit the guide rod 12, restricting its movement in a direction perpendicular to its own axis and guiding it to move linearly within the limiting sleeve 111, thus preventing deviation or skewness.

[0072] In a further embodiment, the first assembly 1 further includes a buffer 13 connected to the side surface of the guide plate 11 opposite to the limiting sleeve 111, and having a clearance hole 131 for the guide rod 12 to pass through. The buffer 13 is configured to abut against an intermediate bearing on the main housing.

[0073] The intermediate bearing is a rolling bearing and is mounted on the main housing. The rotor is inserted into the inner ring of the intermediate bearing. The intermediate bearing supports the rotor and maintains its normal working position and rotational accuracy. The buffer 13, guide plate 11, limit sleeve 111, guide rod 12 and intermediate bearing are coaxially arranged.

[0074] For example, such as Figure 6 As shown, the buffer 13 is sheet-shaped, as... Figure 4 As shown, a second boss 115 protrudes from the side of the guide plate 11 opposite to the limiting sleeve 111. The buffer member 13 is sleeved on the outer periphery of the second boss 115 through the clearance hole 131, thereby achieving the positioning and limiting of the buffer member 13. It can be understood that the second boss 115 is hollow cylindrical so that the guide rod 12 can pass through the second boss 115 and then connect with the rotor.

[0075] The side surface of the buffer 13 facing away from the guide plate 11 abuts against the intermediate bearing. The buffer 13 can provide buffer protection when the intermediate shaft is impacted, reduce the impact force on the intermediate bearing, and prevent the intermediate bearing from being damaged by collision.

[0076] In a further embodiment, the first assembly component 1 further includes a position adjustment mechanism (not shown in the figure), which is connected to the guide plate 11 and the buffer 13 respectively, and is used to adjust the position of the buffer 13.

[0077] Specifically, the position adjustment mechanism is located between the guide plate 11 and the buffer 13. The position adjustment mechanism can adjust the relative position of the buffer 13 and the guide plate 11 so that the intermediate bearing and the buffer 13 can maintain contact. On the one hand, it can prevent the buffer effect of the buffer 13 from being affected by the gap between the intermediate bearing and the buffer 13. On the other hand, it can also prevent the intermediate bearing and the buffer 13 from being too tightly fitted and the force from being too large, which would affect the normal use effect of the intermediate bearing.

[0078] For example, such as Figure 6 and Figure 7 As shown, the buffer 13 has a first connecting hole 132 and a first adjusting hole 133. The first connecting hole 132 is a through hole that penetrates the buffer 13 along the thickness direction of the buffer 13. The first adjusting hole 133 is a blind hole and its opening faces the direction of the guide plate 11.

[0079] like Figure 4 As shown, the guide plate 11 has a second connecting hole 116. The second connecting hole 116 is a through hole that passes through the guide plate 11 along the thickness direction of the guide plate 11. The threaded fastener passes through the first connecting hole 132 and the second connecting hole 116 and is tightened to achieve pre-tightening between the guide plate 11 and the buffer 13.

[0080] like Figure 4 As shown, the guide plate 11 is also provided with a second adjustment hole 117. The second adjustment hole 117 is a through hole that passes through the guide plate 11 along the thickness direction of the guide plate 11. The position adjustment mechanism includes a stud, a screw and other threaded parts and a nut. The threaded parts pass through the second adjustment hole 117, and one end is connected to the first adjustment hole 133 by means of threaded connection or interference fit. By driving the threaded parts to move along their own axial direction, the position of the buffer 13 can be adjusted. When the buffer 13 is just abutting against the intermediate bearing, the nut is put into the end of the threaded parts from the side of the guide plate 11 away from the buffer 13 and tightened, thereby completing the position adjustment of the guide plate 11.

[0081] It is understandable that a distance can be reserved between the guide plate 11 and the buffer 13 before connecting them with threaded fasteners, so that further position adjustment can be made using the threaded fasteners within the reserved distance range.

[0082] Based on any of the above embodiments, the second assembly 2 further includes a pressure-bearing member 23, which is connected to one end of the adjusting member 22 and is sleeved on the second end of the rotor.

[0083] like Figure 10 As shown, the pressure-bearing component 23 has an annular cylindrical structure with one end open. A guide post 232 is provided in the space enclosed by the annular protrusion of the pressure-bearing component 23. The guide post 232 is used to insert into the second end of the rotor. The annular protrusion of the pressure-bearing component 23 is sleeved on the second end of the rotor to realize the connection between the pressure-bearing component 23 and the rotor.

[0084] The side surface of the pressure-bearing member 23 facing away from the outlet end is used to connect with the adjusting member 22.

[0085] Specifically, the connection between the pressure-bearing component 23 and the adjusting component 22 can be abutting, snap-fitting, bonding, threaded connection, integral molding, etc.

[0086] In this embodiment, the pressure-bearing member 23 is used to cover the second end of the rotor, which improves the stress concentration at the end where the rotor is connected to the adjusting member 22, and improves the stability and reliability between the adjusting member 22 and the rotor.

[0087] In a specific embodiment, such as Figure 11 As shown, the pressure-bearing member 23 is provided with a concave structure 231, and the end of the adjusting member 22 abuts against the concave structure 231.

[0088] The concave structure 231 is recessed on one side of the surface opposite to the opening end of the pressure member 23. The end of the adjusting member 22 near the first assembly assembly 1 abuts against the concave structure 231. The adjusting member 22 pushes the rotor connected to the pressure member 23 through contact with the concave structure 231, thereby assembling the rotor into the main housing.

[0089] By providing a concave structure 231 on the pressure-bearing component 23, the contact area between the pressure-bearing component 23 and the adjusting component 22 is increased, the assembly difficulty between the pressure-bearing component 23 and the adjusting component 22 is reduced, and the adaptation effect between the pressure-bearing component 23 and the adjusting component 22 is improved.

[0090] Meanwhile, since the adjusting member 22 abuts against the concave structure 231, during the process of the adjusting member 22 generating axial movement by tightening the thread, the adjusting member 22 and the concave structure 231 generate contact friction, which pushes the pressure-bearing member 23 and the rotor forward, thus avoiding direct contact between the adjusting member 22 and the rotor and causing wear to the rotor.

[0091] Furthermore, the end of the adjusting member 22 that abuts against the concave structure 231 is arc-shaped.

[0092] For example, such as Figure 9 As shown, the end of the rod head 221 that abuts against the concave structure 231 is spherical, which makes the end of the adjusting member 22 better matched with the concave structure 231, and makes the contact surface between the adjusting member 22 and the concave structure 231 smoother, thereby making the adjusting member 22 rotate flexibly and improving the rotor assembly efficiency.

[0093] In a specific embodiment, such as Figure 1 As shown, the second assembly component 2 also includes a connecting rod 24, one end of which is threadedly connected to the mounting base 21, and the other end is threadedly connected to the main housing.

[0094] The connecting rod 24 is rod-shaped or strip-shaped, and the connecting rod 24 passes through the mounting hole 211 of the mounting base 21 to achieve connection with the mounting base 21.

[0095] For example, the connecting rod 24 is a double-threaded rod with external threads at both ends along its length and internal threads on the inner wall of the third connecting hole. The connecting rod 24 is threadedly connected to the mounting base 21 and the main housing, which not only ensures the stability of the connection but also facilitates disassembly and replacement.

[0096] Furthermore, there are multiple connecting rods 24, which are distributed at intervals along the circumference of the mounting base 21. For example... Figure 1 As shown, there are eight connecting rods 24.

[0097] In this embodiment, by setting multiple connecting rods 24 to be distributed circumferentially along the mounting base 21, it is beneficial to improve the connection stability between the mounting base 21 and the main housing, and prevent the mounting base 21 from tilting during the movement of the adjusting member 22, which would affect the assembly accuracy and assembly speed.

[0098] For example, the installation and use process of the motor rotor assembly device is as follows:

[0099] The threaded fastener is passed through the first connecting hole 132 of the buffer 13 and the second connecting hole 116 of the guide plate 11 and tightened to achieve pre-tightening of the guide plate 11 and the buffer 13.

[0100] The threaded fastener is connected to the main housing through the mounting hole 211 of the guide plate 11 to realize the connection between the guide plate 11 and the main housing;

[0101] The buffer 13 is adjusted to abut against the intermediate bearing on the main housing using the position adjustment mechanism;

[0102] The guide rod 12 is passed through the limiting sleeve 111 of the guide plate 11, and the first end of the rotor is connected to the guide rod 12. At this time, the first assembly assembly 1 is connected in place.

[0103] Connect the pressure-bearing component 23 to the second end of the rotor;

[0104] Multiple connecting rods 24 are connected to the side of the main housing opposite to the first assembly assembly 1;

[0105] Connect multiple connecting rods 24 and mounting base 21;

[0106] The adjusting member 22 is passed through the through hole on the mounting base 21, and the rod body 222 is threadedly connected to the mounting base 21, so that the end of the adjusting member 22 abuts against the concave structure 231 of the pressure bearing member 23.

[0107] Tighten the adjusting component 22 to move it toward the side where the first assembly component 1 is located until the rotor is assembled in place;

[0108] After the rotor assembly is completed, remove the pressure-bearing component 23, mounting base 21, connecting rod 24, guide rod 12, guide plate 11 and other components in the reverse order of the motor rotor assembly.
