Description

Technical Field

[0001] This disclosure relates to the field of motor assembly technology, and more specifically, to a disassembly and assembly tooling. Background Technology

[0002] In related technologies, the assembly precision requirements for motors are high, and assembly is required to overcome the magnetic attraction between the stator and rotor, which presents certain difficulties. Utility Model Content

[0003] The purpose of this disclosure is to provide a disassembly and assembly tooling that facilitates the assembly of an electric motor.

[0004] To achieve the above objectives, this disclosure provides a disassembly and assembly fixture for disassembling and assembling the stator and rotor of a motor. The stator includes a first housing and a second housing. The disassembly and assembly fixture includes: The support base is provided with a first fixing part for fixing the first housing; A floating mechanism, comprising a floating seat, a linkage seat, and a driving device, wherein the floating seat is provided with a second fixing part for fixing the second housing, the linkage seat is connected to the floating seat and the linkage seat and the floating seat are respectively disposed on both sides of the support seat, and the driving device is tractively connected to the floating seat for driving the floating seat and the linkage seat to move, so that the floating seat moves closer to or away from the support seat; and The ejection mechanism includes a pusher member movably mounted on the linkage seat and extending toward the floating seat through the support seat to jointly push against the rotor with the floating seat. The first fixing part and the second fixing part are configured such that the first housing, the second housing and the rotor are arranged coaxially.

[0005] With the above structure, while ensuring the coaxiality of the rotor and stator, it is easy for workers to overcome the magnetic attraction between the rotor and stator to insert or remove the rotor from the stator, realizing the assembly and disassembly of the stator and rotor. At the same time, it can also prevent the rotor from deviating from the expected path during the assembly and disassembly process, thereby avoiding situations such as the rotor and stator rubbing against each other, and improving the reliability of the rotor and stator installation.

[0006] In some possible implementations, the support base is provided with a through hole, and the ejection mechanism includes an actuating device that is kinetically connected to the abutting member. The actuating device drives the abutting member to extend through the through hole to abut against the rotor or to retract from the through hole to move away from the rotor. Thus, with the distance between the floating base and the linkage base remaining constant, the actuating device drives the abutting member to move relative to the linkage base, thereby achieving both clamping and releasing of the rotor.

[0007] In some possible implementations, the ejection mechanism includes a nut seat, the abutting member is configured as a screw, the nut seat is mounted on the linkage seat and sleeved on the screw, and the actuating device is used to drive the screw to rotate, so that the screw moves to extend from the through hole and abut against the rotor or retract from the through hole and move away from the rotor. By configuring the nut seat and the screw, the screw can be held in the desired position after moving to it, saving the operation steps of fixing the screw and making it easier for operators to use.

[0008] In some possible implementations, the actuation device is configured as a first operating rocker wheel, which is sleeved on the screw and used to operate the screw to rotate. The first operating rocker wheel allows for adjustable movement speed of the abutment, facilitating timely adjustment of the rotor's position by the operator during tightening or releasing of the rotor.

[0009] In some possible implementations, the floating mechanism includes a connecting rod, and the linkage seat is connected to the floating seat via the connecting rod. In this way, the connecting rod enables synchronous movement between the floating seat and the linkage seat.

[0010] In some possible implementations, the floating mechanism includes a base and a mounting frame. The mounting frame and the support seat are mounted on the base, and the floating seat and the linkage seat are slidably mounted on the mounting frame. The mounting frame guides the movement of the floating seat and the linkage seat relative to the support seat. The mounting frame facilitates the movement of the floating seat and the linkage seat relative to the support seat.

[0011] In some possible implementations, the floating mechanism includes a first linear bearing, which is sleeved on the mounting frame and connected to the floating seat for movement along the mounting frame together with the floating seat; and / or, the floating mechanism includes a second linear bearing, which is sleeved on the mounting frame and connected to the linkage seat for movement along the mounting frame together with the linkage seat. This facilitates the movement of the floating seat and linkage seat relative to the mounting frame and also provides some guidance for their movement.

[0012] In some possible implementations, the floating mechanism includes a fixed base and a transmission rod. The two ends of the mounting bracket are connected to the fixed base and the base, respectively. The drive device is mounted on the fixed base, and the transmission rod is drively connected to the drive device, with one end of the transmission rod connected to the floating base. The fixed base provides a mounting position for the drive device, allowing the drive device to drive the floating base to move relative to the fixed base, i.e., relative to the base and support, via the transmission rod.

[0013] In some possible implementations, the floating mechanism includes a transmission structure comprising meshing gears and a rack, with the rack formed on the transmission rod, and the gears being drive-connected to the drive device. By arranging the rack and gears, the rotation of the drive device can be converted into linear motion along the extension direction of the rack. Thus, by arranging the rack along the direction of movement of the floating seat and fixing it to the floating seat, the floating seat can move closer to or away from the support.

[0014] In some possible implementations, the drive device is configured as a second operating rocker wheel, which drives the transmission gear to rotate. By using the second operating rocker wheel, the operator can control the speed of the transmission gear's rotation, thereby making the speed at which the transmission rack drives the floating seat adjustable. This allows the operator to easily adjust the rotor's movement path during the assembly and disassembly of the rotor relative to the stator.

[0015] Through the above technical solution, the disassembly and assembly fixture provided in this disclosure, when used to disassemble and assemble the stator and rotor, allows the stator to include a first housing and a second housing. A first fixing part is used to fix the first housing, and a second fixing part is used to fix the second housing. A pusher moves relative to the linkage seat and passes through the support seat to, together with the floating seat, push the rotor against the second housing and the pusher. Thus, during the disassembly and assembly of the stator and rotor, the drive device drives the floating seat to move closer to or away from the support seat, thereby causing the rotor and the second housing to move closer to or away from the first housing fixed on the support seat. This overcomes the magnetic attraction between the rotor and stator, allowing the rotor to be inserted into or removed from the first housing, achieving the disassembly and assembly of the rotor and stator. During the disassembly and assembly process, the push-out mechanism and the floating seat press against the rotor, preventing deviation of the rotor's movement path during disassembly and assembly, thus ensuring a uniform gap between the rotor and stator and preventing damage caused by rubbing against the stator. Furthermore, by designing the positions of the first and second fixing parts on the support base and the floating base respectively, it is easier for staff to control the coaxiality between the rotor and the stator, further ensuring that the gap between the rotor and the stator is uniform during installation and improving installation reliability.

Detailed Implementation

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, the terms "first," "second," etc., used herein are for distinguishing one element from another and do not have sequential or material significance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0021] Based on the specific embodiments provided in this disclosure, refer to Figure 1-2As shown, a disassembly and assembly fixture is provided for disassembling and assembling the stator 52 and rotor 51 of a motor. The stator includes a first housing and a second housing. The disassembly and assembly fixture includes: a support base 2, which is provided with a first fixing part 22 for fixing the first housing 521; a floating mechanism, which includes a floating seat 311, a linkage seat 312 and a drive device. The floating seat 311 is provided with a second fixing part 32 for fixing the second housing 522. The linkage seat 312 is connected to the floating seat 311 and the linkage seat 311 are respectively provided on both sides of the support base 2. The drive device is driven to the floating seat 311. The user drives the floating seat 311 and the linkage seat 312 to move so that the floating seat 311 moves closer to or away from the support base 2; and an ejection mechanism 4, which includes a pusher 41. The pusher 41 is movably installed on the linkage seat 312 and extends toward the floating seat 311 through the support base 2 to press the rotor 51 together with the floating seat 311.

[0022] Through the above technical solution, the disassembly and assembly tooling provided in this disclosure, when used to disassemble and assemble the stator 52 and the rotor 51, the stator 52 may include a first housing 521 and a second housing 522, wherein the first fixing part 22 is used to fix the first housing 521, the second fixing part 32 is used to fix the second housing 522, and the abutting member 41 moves relative to the linkage seat 312 and passes through the support seat 2, so as to work together with the floating seat 311 to abut the rotor 51 between the second housing 522 and the abutting member 41. In this way, when disassembling and assembling the stator 52 and the rotor 51, the driving device drives the floating seat 311 to move closer to or away from the support seat 2, thereby driving the rotor 51 and the second housing 522 to move closer to or away from the first housing 521 fixed on the support seat 2, so as to overcome the magnetic attraction between the rotor 51 and the stator 52 and insert or remove the rotor 51 into or out of the first housing 521, thereby realizing the disassembly and assembly of the rotor 51 and the stator 52. During disassembly and assembly, the ejector mechanism 4 and the floating seat 311 hold the rotor 51 in place, preventing deviation of the rotor 51's movement path during disassembly and assembly. This ensures a uniform gap between the rotor 51 and the stator 52, preventing damage caused by friction between them. Furthermore, the design of the first fixing part 22 and the second fixing part 32 on the support base 2 and the floating seat 311 respectively facilitates the operator's control of the coaxiality between the rotor 51 and the stator 52, further ensuring a uniform gap between the rotor 51 and the stator 52 during installation and improving installation reliability.

[0023] It should also be noted that, under normal circumstances, reference Figure 2As shown, the stator 52 may include a first housing 521 and a second housing 522. During the assembly and disassembly process, the first housing 521 can be fixed to the support base 2 by the first fixing part 22, and the second housing 522 can be fixed to the side of the floating base 311 facing the first housing 521. The rotor 51 is pressed between the second housing 522 and the abutment 41. After the rotor 51 is installed and inserted into the first housing 521, the end face of the second housing 522 can abut against the end face of the first housing 521, thereby completing the installation between the rotor 51 and the stator 52. Based on the above embodiments, a positioning structure can be provided between the second housing 522 and the rotor 51 to facilitate positioning between the rotor 51 and the second housing 522. The positioning structure can be constructed in any suitable form. For example, a positioning hole can be provided on the second housing 522, and a positioning pin can be provided on the rotor 51 to cooperate with the positioning hole. Alternatively, a positioning countersunk hole can be provided on the second housing 522, with the end face of the rotor 51 abutting against the stepped surface of the positioning countersunk hole, and the peripheral side surface of the rotor 51 fitting against the inner wall surface of the positioning countersunk hole. All of the above can achieve positioning between the second housing 522 and the rotor 51, thereby ensuring the coaxiality between the second housing 522 and the stator 52. This disclosure does not impose any specific limitations on this.

[0024] Based on the above embodiments, it should be added that, in this disclosure, the first fixing part 22 and the second fixing part 32 can be any suitable structure to realize the detachable connection between the rotor 51 and the floating seat 311, and the stator 52 and the support seat 2. This disclosure does not impose any specific limitations on this. As an exemplary embodiment, the first fixing part 22 and the second fixing part 32 can be configured as a first mounting hole and a second mounting hole respectively opened on the support base 2 and the floating base 311. The first housing 521 is detachably fixed to the support base 2 by fasteners (such as bolts) passing through the first mounting hole, and the second housing 522 is detachably fixed to the floating base 311 by fasteners (such as bolts) passing through the second mounting hole. In this case, by arranging the positions of the first mounting hole and the second mounting hole on the support base 2 and the floating base 311, the coaxiality between the first housing 521 and the second housing 522 can be ensured. The positioning member can ensure the coaxiality between the rotor 51 and the second housing 522, thereby achieving the purpose of ensuring that the gap between the rotor 51 and the stator 52 is uniform during the disassembly and assembly process, and improving the reliability of the disassembly and assembly between the rotor and the stator.

[0025] In the disassembly and assembly fixture provided in this disclosure, the ejection mechanism 4 can be constructed in any suitable form, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 1 or Figure 2As shown, the support base 2 may be provided with a through hole 21, and the ejection mechanism 4 may include an actuating device. The actuating device may be driven to the abutment member 41. The actuating device drives the abutment member 41 to extend through the through hole 21 to abut against the rotor 51 or to retract from the through hole 21 to move away from the rotor 51. That is, the abutment member 41 can move through the support base 2 through the through hole 21, extend through the through hole 21 to abut against the rotor 51 under the drive of the actuating device, or retract from the through hole 21 to release the rotor 51. The actuating device may be mounted on the linkage base 312, and the abutment member 41 is driven to the actuating device, thereby realizing the movable installation of the abutment member 41 on the linkage base 312.

[0026] Based on the above embodiments, as an exemplary embodiment, refer to Figure 2 As shown, the ejection mechanism 4 may include a nut seat 42, and the abutment member 41 may be configured as a screw. The nut seat 42 may be mounted on the linkage seat 312 and sleeved on the screw. An actuating device is used to drive the screw to rotate, so that the screw can move to extend from the through hole 21 and abut against the rotor 51, or retract from the through hole 21 and move away from the rotor 51. Since the nut seat 42 is fixed to the linkage seat 312 and threadedly engaged with the screw, the movement of the screw relative to the nut seat 42, i.e., the linkage seat 312, can be achieved by rotating the screw through the actuating device. The arrangement of the nut seat 42 and the screw allows the screw to remain in the desired position after moving to that position, saving the operation steps of fixing the screw and making it convenient for operators to use.

[0027] The actuation device can be configured as a first operating rocker wheel 43, which can be sleeved on the screw and used to operate the screw to rotate. In this way, the operator can adjust the movement speed of the screw relative to the linkage seat 312 by using the first operating rocker wheel 43. Thus, during the process of rotating the screw to tighten the rotor 51, the position of the rotor 51 can be adjusted in time to ensure that the rotor 51 is tightened between the floating seat 311 and the screw in the expected manner.

[0028] In other embodiments, the actuation device may also be configured as a rotary motor, which may be fixed on the side of the linkage 312 away from the rotor 51. The rotary motor includes an output shaft that passes through the linkage 312 and is connected to the screw drive. In this way, when the rotary motor is working, the output shaft can drive the screw to rotate, and the screw can also be movably installed on the linkage 312. This disclosure does not impose any specific limitations on this.

[0029] In some other embodiments, the actuating device may also be configured as a linear motor, which may be fixed to the linkage seat 312 and include a drive shaft that passes through the linkage seat 312 and is connected to the abutment member 4. In this way, when the linear motor is working, the abutment member 4 can move relative to the linkage seat 312, which can also achieve the clamping of the rotor 51. This disclosure does not impose any specific limitations on this.

[0030] In the disassembly and assembly work provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 1 or Figure 2 As shown, the floating mechanism may include a connecting rod 313, and the linkage seat 312 and the floating seat 311 can be connected by the connecting rod 313. The connecting rod 313 ensures synchronous movement between the linkage seat 312 and the floating seat 311, so that after the abutment member 41 presses against the rotor 51, the floating seat 311 can drive the linkage seat 312 and the rotor 51 to move synchronously. Furthermore, in this disclosure, the support base 2 is provided with a floating seat 311 and a linkage seat 312 on its upper and lower sides respectively. Thus, when the drive device drives the floating seat 311 to move, the linkage seat 312 can be driven to move together through the connecting rod 313. Since the linkage seat 312 is located below the support base 2, when the floating seat 311 moves towards the support base 2, the linkage seat 312 moves away from the support base 2, avoiding interference from the support base 2 on the movement of the linkage seat 312. This allows the floating seat 311 to be as close as possible to the support base 2, ultimately achieving the installation of the rotor 51 within the stator 52.

[0031] In the disassembly and assembly fixtures provided in this disclosure, the floating mechanism can be constructed in any suitable form, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 1 As shown, the floating mechanism may include a base 1 and a mounting frame 33. The mounting frame 33 and the support seat 2 can be mounted on the base 1. The floating seat 311 and the linkage seat 312 can be slidably mounted on the mounting frame 33. The mounting frame 33 is used to guide the movement of the floating seat 311 and the linkage seat 312. That is, the floating seat 311 and the linkage seat 312 are slidably connected to the base 1 through the mounting frame 33, while the support seat 2 is fixed on the base 1, thereby facilitating the movement of the floating seat 311 and the linkage seat 312 relative to the support seat 2.

[0032] Furthermore, under the condition that the rotor 51 is completely detached from the stator 52, the minimum distance between the floating seat 311 and the support seat 2 can be determined as the sum of the heights of the stator 52 and the rotor 51 in their direction of motion. Since the support seat 2 is fixed to the base 1, the distance between the support seat 2 and the base 1 is determined. Thus, the distance between the floating seat 311 and the base 1 when the rotor 51 is completely detached from the stator 52 can be determined, which is the sum of the heights of the rotor 51, the stator 52, and the support seat 2 and the base 1. At this time, in order to ensure the movement stroke of the floating seat 311, the height of the mounting bracket 33 relative to the base 1 is determined. It should also be noted that, since the floating seat 311 and the linkage seat 312 are respectively located on the upper and lower sides of the support seat 2, and the support seat 2 is fixed to the base 1, when the rotor 51 is installed into the stator 52, in order to avoid the base 1 interfering with the movement of the linkage seat 312, and thus interfering with the movement of the floating seat 311, the distance between the floating seat 311 and the base 1 should be at least greater than or equal to the movement stroke of the floating seat 311. That is, the distance between the support seat 2 and the base 1 should be at least greater than or equal to the sum of the axial heights of the rotor 51 and the stator 52.

[0033] It should be added that, in this disclosure, the stator 52 may include a first housing 521 and a second housing 522. The first housing 521 is fixed to the support base 2 by the first fixing part 22, and the second housing 522 is fixed to the side of the floating base 311 facing the linkage base 312. The rotor 51 is pressed between the second housing 522 and the abutting member 41. When the rotor 51 is fully installed in the stator 52, the two opposite end faces of the first housing 521 and the second housing 522 abut against each other. At this time, the height of the stator 52 in its axial direction is the sum of the heights of the first housing 521 and the second housing 522.

[0034] Based on the above embodiments, as an exemplary embodiment, refer to Figure 1 or Figure 2 As shown, the floating mechanism may include a first linear bearing 341, which is sleeved on the mounting frame 33 and connected to the floating seat 311 to move along the mounting frame 33 together with the floating seat 311; and / or, the floating mechanism may include a second linear bearing 342, which is sleeved on the mounting frame 33 and connected to the linkage seat 312 to move along the mounting frame 33 together with the linkage seat 312. The arrangement of the first linear bearing 341 and the second linear bearing 342 facilitates the movement of the floating seat 311 and the linkage seat 312 relative to the mounting frame 33, and also provides a certain guiding effect for the movement of the floating seat 311 and the linkage seat 312 relative to the mounting frame 33, thereby improving the reliability of the movement of the floating seat 311 and the linkage seat 312.

[0035] Based on the above embodiments, the floating seat 311 can achieve movement relative to the base 1 in any suitable form, and this disclosure does not impose specific limitations in this regard. As an exemplary embodiment, refer to... Figure 1 or Figure 2 As shown, the floating mechanism may include a fixed base 35 and a transmission rod 36. The two ends of the mounting bracket 33 can be connected to the fixed base 35 and the base 1 respectively. The drive device can be mounted on the fixed base 35, and the transmission rod 36 can be connected to the drive device. One end of the transmission rod 36 can be connected to the floating seat 311. Thus, the drive device, fixed to the fixed base 35, can drive the floating seat 311 to reciprocate between the fixed base 35 and the base 1 via the transmission rod 36, i.e., the floating seat 311 moves closer to or further away from the base 1, thereby enabling the installation and detachment of the rotor 51 and the stator 52. The fixed base 35 provides an installation position for the drive device, allowing the drive device to drive the floating seat 311 to move relative to the fixed base 35, i.e., relative to the base 1 and the support 2, via the transmission rod 36.

[0036] In one embodiment, the drive device can be configured as a linear motor, which is fixed on the fixed base 35 and connected to the transmission rod 36. The end of the transmission rod 36 away from the linear motor can pass through the fixed base 35 and be fixed to the floating seat 311. When the linear motor is working, it can drive the floating seat 311 to move relative to the fixed base 35. Alternatively, the drive device can also be configured as a cylinder, a linear module, or other mechanism, and this disclosure does not impose specific limitations on this.

[0037] In another implementation, refer to Figure 1 or Figure 2 As shown, the floating mechanism may include a transmission structure, which may include meshing transmission gears and a transmission rack. The transmission rod 36 may have a transmission rack, and the transmission gear is connected to the drive device. In this case, the drive device may be configured as a rotary motor. The output shaft of the rotary motor is fixedly connected to the transmission gear. The operation of the rotary motor can drive the transmission gear to rotate through the output shaft. Since the transmission gear meshes with the transmission rack, the rotation of the transmission gear can be converted into linear motion of the transmission rack along its own extension direction. In this way, the transmission rod 36 can drive the floating seat 311 to move relative to the fixed seat 35, and then the disassembly and assembly of the rotor 51 and the stator 52 can be realized by using the disassembly and assembly tooling of this disclosure.

[0038] Based on the above implementation method, as another implementation method, refer to Figure 1 or Figure 2As shown, the drive device can be configured as a second operating rocker wheel 38, which can be used to drive the transmission gear to rotate. In this way, the operator can control the speed of rotating the second operating rocker wheel 38, thereby making the speed at which the transmission rod 36 drives the floating seat 311 adjustable, so that the operator can easily adjust the movement speed of the rotor 51 in a timely manner during the disassembly and assembly of the rotor 51 relative to the stator 52.

[0039] In the disassembly and assembly tooling provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 1 or Figure 2 As shown, the base 1 may be equipped with a moving device to facilitate the movement of the disassembly and assembly tool to any desired position by the operator. The moving device may be constructed as multiple pairs of moving wheels 11, which may be located at the bottom of the base 1. This disclosure does not impose any specific limitations on this.

[0040] In summary, when installing the rotor 51 and stator 52, the disassembly and assembly fixture provided in this disclosure first fixes the first housing 521 to the support base 2, and fixes the second housing 522 to the side of the floating seat 311 facing the first housing 521. Then, the position of the rotor 51 is determined by the positioning structure set between the second housing 522 and the rotor 51. The first operating rocker wheel 43 is rotated to press the rotor 51 against the abutment 41 and the second housing 522, and the second operating rocker wheel 38 is rotated to drive the floating seat 311. The second housing 522 and the rotor 51 move toward the first housing 521, while the linkage seat 312 and the abutting member 41 move away from the support seat 2 until the rotor 51 is fully inserted into the first housing 521 and the second housing 522 abuts against the first housing 521. Finally, the first operating rocker wheel 43 is rotated to release the rotor 51 from the abutting member 41, and then the first housing 521 and the second housing 522 are removed from the support seat 2 and the floating seat 311. This completes the installation between the stator 52 and the rotor 51. When the disassembly and assembly tooling provided in this disclosure is used to separate the rotor 51 and the stator 52, the first housing 521 and the second housing 522 are first fixed on the floating seat 311 and the support seat 2, respectively. The first operating rocker wheel 43 is rotated to press the rotor 51 between the second housing 522 and the abutment 41. Then, the first operating rocker wheel 43 and the second operating rocker wheel 38 are rotated synchronously. Under the condition that the rotor 51 is pressed between the second housing 522 and the abutment 41, the floating seat 311, the second housing 522 and the rotor 51 move away from the first housing 521, and the linkage seat 312 and the abutment 41 move towards the support seat 2 until the first housing 521 and the second housing 522 separate and the rotor 51 is completely separated from the stator 52. Finally, the first operating rocker wheel 43 is rotated to release the rotor 51 from the abutment 41, and then the first housing 521 and the second housing 522 are removed from the support seat 2 and the floating seat 311. Thus, the separation between the stator 52 and the rotor 51 is achieved.

However, this disclosure is not limited to the specific details of the above embodiments.
