Description

Technical Field

[0001] This invention relates to the field of stator and rotor installation technology, and in particular to an auxiliary device and method for installing stator and rotor of a motorcycle magneto. Background Technology

[0002] The motorcycle magneto is the core power source of the engine ignition system and the vehicle's power supply system. Its stator and rotor adopt an assembly structure of an outer rotor and an inner stator. During assembly, the rotor must first be fixed to the designated journal of the engine crankshaft by interference fit or locking with locating pins and bolts. Then, the stator is installed in the inner mounting position of the engine end cover by positioning with locating pins and bolts. Finally, the rotor and stator are coaxially wrapped and assembled by the mating of the engine end cover and the crankcase. The rotor rotates at high speed with the crankshaft, while the stator remains fixed. The two work together to complete the conversion of mechanical energy into electrical energy.

[0003] In the aforementioned prior art, because the stator is wound with dense enameled wire windings on the outside, and the final coaxial fit between the stator and rotor needs to be completed when the engine end cover is docked with the crankcase, there is a lack of effective guiding and limiting structures in the assembly of the stator and rotor. The inner wall of the rotor is prone to direct collision or sliding friction with the outer windings of the stator, which can lead to damage to the insulation layer of the stator windings, short circuits, and in severe cases, even direct breakage of the winding wires. This not only significantly reduces the assembly qualification rate of the motorcycle magneto, but also increases the loss of parts and labor costs during rework. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device and method for installing the stator and rotor of a motorcycle magneto. This addresses the problem in the prior art where the stator has dense enameled wire windings on its exterior, and the final coaxial fit between the stator and rotor must be completed when the engine end cover is connected to the crankcase. Therefore, during the assembly of the stator and rotor, there is a lack of effective guiding and limiting structures, making it easy for the inner wall of the rotor to directly collide or slide against the outer windings of the stator. This leads to damage to the insulation layer of the stator windings, short circuits, and in severe cases, even direct breakage of the winding wires. This not only significantly reduces the assembly pass rate of the motorcycle magneto but also increases the loss of parts and labor costs during rework.

The multiple pulleys are respectively disposed on the upper limit plate and the lower limit plate.

[0010] The mounting assembly further includes multiple stator fixing mechanisms, which are sequentially arranged inside the stator mounting shaft. The stator fixing mechanism includes a stator abutment component and a stator abutment block. The stator abutment component is disposed inside the stator mounting shaft. The output end of the stator abutment component is fixedly connected to the stator abutment block. The stator abutment block abuts against the inner wall of the stator.

[0011] The mounting assembly further includes a rotor fixing unit, which is disposed on the rotor mounting shaft; The rotor fixing unit includes multiple rotor pushing mechanisms, a rotating cylinder, an internal driving component, an internal driving shaft, a gear, a gear ring, and a rotor limiting mechanism.

At this time, the rotor is moved and mounted on the rotor mounting shaft. The magneto housing and end cover will be moved to one side of the rotor and the stator respectively, and the lateral movement of the magneto housing and end cover will be limited by the upper limit plate and the lower limit plate.

The rotor test unit is activated and moved closer to the stator mounting shaft, so that the rotor is fitted onto the outside of the stator. The rotor rotates, and it is observed whether the rotor and stator make contact. If there is no contact, the rotor and stator are separated, and the position interchange mechanism is activated, so that the rotor mounting shaft is aligned with the rotor test unit. At this time, the rotor is moved and installed on the rotor mounting shaft. The magneto housing and end cover are moved to one side of the rotor and stator respectively, and the lateral movement of the magneto housing and end cover is limited by the upper limit plate and the lower limit plate. After the outer casing and end cover are moved laterally, they approach the rotor and stator, and the rotor and stator are respectively detached from the rotor mounting shaft and the stator mounting shaft. The operator performs bolt fixing operation to install the rotor and stator onto the magneto outer casing and end cover. The magneto outer casing and end cover are then closed and fixed. Thus, before the stator and rotor are installed inside the magneto outer casing and end cover, a test run is performed to ensure normal operation and that the outside of the stator will not contact the rotor before installation. During the installation process, the upper limit plate and the lower limit plate are used to limit the movement path of the magneto end cover and outer casing, avoid deviation, and ensure that there is no contact between the stator and rotor after installation. Ultimately, this significantly improves the assembly qualification rate of the motorcycle magneto. Attached Figure Description

Detailed Implementation

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0027] Please see Figures 1 to 7 The present invention provides an auxiliary device for installing a stator and rotor of a motorcycle magneto, including a base 1, a rotor 2, a stator 3 and an installation assembly, wherein the rotor 2 and the stator 3 are both disposed above the base 1; The mounting assembly includes a rotor mounting shaft 4, a stator mounting shaft 5, a position interchange mechanism, a rotor 2 test rotation unit, multiple upper limit plates 6, and multiple lower limit plates 7. The position interchange mechanism and the rotor 2 test rotation unit are sequentially arranged above the base 1. The rotor mounting shaft 4 and the stator mounting shaft 5 are symmetrically arranged on the position interchange mechanism. The rotor 2 is mounted on the rotor 2 test rotation unit. The stator 3 is mounted on the outside of the stator mounting shaft 5. The multiple upper limit plates 6 and the multiple lower limit plates 7 are respectively located above and below the rotor mounting shaft 4 and the stator mounting shaft 5.

[0028] In this embodiment, the rotor 2 is mounted on the rotor 2 test unit, and the stator 3 is mounted on the stator mounting shaft 5. The rotor 2 test unit is started and moved close to the stator mounting shaft 5, so that the rotor 2 is sleeved on the outside of the stator 3. The rotor 2 rotates, and it is observed whether the rotor 2 and the stator 3 make contact. If there is no contact, the rotor 2 and the stator 3 are separated, and the position interchange mechanism is activated so that the rotor mounting shaft 4 is aligned with the rotor 2 test unit. At this time, the rotor 2 is moved and mounted on the rotor mounting shaft 4. The magneto housing and end cover are moved to one side of the rotor 2 and the stator 3 respectively, and the lateral movement of the magneto housing and end cover is limited by the upper limit plate 6 and the lower limit plate 7. After moving, the rotor 2 and stator 3 are brought closer together, and the rotor 2 and stator 3 are respectively separated from the rotor mounting shaft 4 and the stator mounting shaft 5. The operator performs bolt fixing operation to install the rotor 2 and stator 3 on the magneto housing and end cover. The magneto housing and end cover are then closed and fixed. Thus, before the stator 3 and rotor 2 are installed inside the magneto housing and end cover, a test run is performed to ensure normal operation and that the outside of the stator 3 will not contact the rotor 2 before installation. During the installation process, the upper limit plate 6 and the lower limit plate 7 are used to limit the movement path of the magneto end cover and housing, prevent deviation, and ensure that there is no contact between the stator 3 and rotor 2 after installation. This significantly improves the assembly qualification rate of the motorcycle magneto.

[0029] Furthermore, the position interchange mechanism includes a top bracket 8, an interchangeable drive component 9, an interchangeable drive shaft 10, an interchangeable support block 11, and multiple cameras 12. The top bracket 8 is mounted above the base 1, the interchangeable drive component 9 is positioned above the top bracket 8, one end of the interchangeable drive shaft 10 is fixedly connected to the output end of the interchangeable drive component 9, and the other end of the interchangeable drive shaft 10 passes through the top bracket 8 and is rotatably connected to the base 1. The interchangeable support block 11 is fixedly connected to the interchangeable drive shaft 10 and is sleeved on the outside of the interchangeable support block 11. The multiple cameras 12 are sequentially arranged on the interchangeable support block 11.

[0030] In this embodiment, the interchangeable drive component 9 is a self-locking motor. After starting, it drives the interchangeable drive shaft 10 to rotate, and the interchangeable drive shaft 10 drives the interchangeable support block 11 to rotate, thereby causing the rotor mounting shaft 4 and the stator mounting shaft 5 to interchange positions. When the rotor 2 is tested and engaged with the stator 3 on the rotor 2 test rotation unit, the camera 12 can observe it and upload the image to the upper system so that the staff can observe the test rotation situation and determine whether the inner wall of the rotor 2 is in contact with the outside of the stator 3.

[0031] Furthermore, the rotor 2 test rotation unit includes a rotor lateral movement component 13, a lateral movement plate 14, a test rotation drive component 15, a U-shaped frame 16, and two abutment mechanisms. The rotor lateral movement component 13 is disposed on the inner top wall of the top support 8. The lateral movement plate 14 is disposed at the output end of the rotor lateral movement component 13. The test rotation drive component 15 is disposed on one side of the lateral movement plate 14. The output end of the test rotation drive component 15 passes through the lateral movement plate 14 and is fixedly connected to the U-shaped frame 16. The two abutment mechanisms are symmetrically disposed on the U-shaped frame 16.

[0032] In this embodiment, the rotor lateral movement component 13 is an electric slide rail, and the test rotation drive component 15 is a self-locking motor. First, the rotor 2 is placed inside the U-shaped frame 16 and held and limited by the two abutment mechanisms. Then, the rotor lateral movement component 13 is activated, and the lateral movement plate 14 is moved. The lateral movement plate 14 moves the rotor 2 to the outside of the stator 3. At this time, the test rotation drive component 15 is activated, driving the rotor 2 to rotate, thereby observing whether the rotor 2 and the stator 3 are in contact. Then, a test rotation is performed before assembling the magneto housing and end cover. After achieving no contact, the installation is carried out, thereby improving the magneto assembly qualification rate.

[0033] Furthermore, the supporting mechanism includes a supporting component 17 and a supporting plate 18. The supporting component 17 is disposed on one side of the U-shaped frame 16. The output end of the supporting component 17 passes through the U-shaped frame 16 and is fixedly connected to the supporting plate 18. The supporting plate 18 is in contact with the outer wall of the rotor 2.

[0034] In this embodiment, the supporting component 17 is a self-locking cylinder. After activation, it drives the supporting plate 18 to move and abut against the outer wall of the rotor 2, thereby fixing the rotor 2 inside the U-shaped frame 16.

[0035] Furthermore, the installation assembly also includes multiple limiting mechanisms, which are sequentially arranged above the base 1, and multiple upper limiting plates 6 and multiple lower limiting plates 7 are respectively arranged on the corresponding limiting mechanisms; The limiting mechanism includes a lifting component 19 and a plurality of pulleys 20. The lifting component 19 is disposed above the base 1. The output end of the lifting component 19 is provided with the upper limit plate 6 or the lower limit plate 7. The plurality of pulleys 20 are respectively disposed on the upper limit plate 6 and the lower limit plate 7.

[0036] In this embodiment, the lifting component 19 is an electric slide rail. After starting, it drives the upper limit plate 6 to move down or the lower limit plate 7 to move up, thereby clamping and limiting the magneto end cover or housing between the upper limit plate 6 and the lower limit plate 7, restricting it to move only laterally, avoiding deviation when docking with the rotor 2 or the stator 3, and ensuring that the non-contact effect during trial rotation can continue into the end cover and housing. At the same time, when the upper limit plate 6 and the lower limit plate 7 clamp the end cover or housing, they rely on the pulley 20 for contact. The pulley 20 is equipped with a pressure sensor, which can monitor whether it is in contact with the end cover or housing.

[0037] Furthermore, the mounting assembly also includes multiple stator 3 fixing mechanisms, which are sequentially arranged inside the stator mounting shaft 5; The stator 3 fixing mechanism includes a stator abutment component 21 and a stator abutment block 22. The stator abutment component 21 is disposed inside the stator mounting shaft 5. The output end of the stator abutment component 21 is fixedly connected to the stator abutment block 22. The stator abutment block 22 abuts against the inner wall of the stator 3.

[0038] In this embodiment, the stator abutment component 21 is a self-locking cylinder. After activation, it drives the stator abutment block 22 to move and contact the inner wall of the stator 3 to achieve fixation, so as to carry out trial rotation and installation operations.

[0039] Furthermore, the mounting assembly also includes a rotor 2 fixing unit, which is disposed on the rotor mounting shaft 4; The rotor 2 fixing unit includes multiple rotor 2 pushing mechanisms, a rotating cylinder 23, an internal driving component 24, an internal driving shaft 25, a gear 26, a gear ring 27, and a rotor 2 limiting mechanism. The rotor mounting shaft 4 has a first groove 28. The rotating cylinder 23 is rotatably connected to the rotor mounting shaft 4 and is located inside the first groove 28. The multiple rotor 2 pushing mechanisms are sequentially distributed around the outside of the rotating cylinder 23. The internal driving component 24 is disposed on the inner sidewall of the first groove 28. The output end of the internal driving component 24 is fixedly connected to one end of the internal driving shaft 25. The other end of the internal driving shaft 25 passes through the gear 26 and is rotatably connected to the inner wall of the first groove 28. The gear ring 27 is disposed on the inner wall of the rotating cylinder 23 and meshes with the gear 26. The rotor 2 limiting mechanism is disposed at one end of the rotor mounting shaft 4.

[0040] In this embodiment, the rotor 2 pushing mechanism is used to push the rotor 2, which is mounted on the rotor mounting shaft 4, into the housing of the magneto, so that it contacts the inner wall of the housing for easy bolt tightening. Before pushing, the internal drive component 24 can be activated to drive the internal drive shaft 25 to rotate. The internal drive shaft 25 drives the gear 26 to rotate. The gear 26 meshes with the gear ring 27, driving the gear ring 27 to rotate. The gear ring 27 drives the rotating drum 23 to rotate, thereby adjusting the position of the multiple rotor 2 pushing mechanisms so that the rotor 2 pushing mechanisms can avoid the bolt mounting holes on the rotor 2, preventing the bolt mounting holes from being blocked during pushing and thus preventing bolt installation and tightening. In addition, when performing position interchange operations, in order to improve the stability of the rotor 2 and prevent the rotor 2 from slipping off the rotor mounting shaft 4, the rotor 2 limiting mechanism needs to be activated to limit the rotor 2 on the rotor mounting shaft 4, so that it cannot detach from the rotor mounting shaft 4.

[0041] Furthermore, the rotor 2 driving mechanism includes a primary rotor driving component 29, a secondary rotor driving component 30, and a rotor pusher block 31. The primary rotor driving component 29 is disposed outside the rotating drum 23. The output end of the primary rotor driving component 29 is provided with the secondary rotor driving component 30. The output end of the secondary rotor driving component 30 is fixedly connected to the rotor pusher block 31.

[0042] In this embodiment, the first-stage rotor pushing component 29 is an electric slide rail. After starting, it drives the second-stage rotor pushing component 30 to move forward. At the same time, the second-stage rotor pushing component 30 is a self-locking cylinder. After starting, it drives the rotor pushing block 31 to move forward, thereby pushing out the rotor 2 sleeved on the rotor mounting shaft 4 and pressing it against the inner wall of the magneto housing. After pressing, the bolts can be tightened.

[0043] Furthermore, the rotor 2 limiting mechanism includes a screw motor 32, a wedge block 33, two telescopic limiting blocks 34, and two springs 35. The rotor mounting shaft 4 also has two openings 36 and a second groove 37. Both openings 36 are connected to the second groove 37. The screw motor 32 is disposed inside the second groove 37. The wedge block 33 is adapted to the output end of the screw motor 32. The two telescopic limiting blocks 34 are slidably connected to the corresponding openings 36. One end of each of the two springs 35 is movably connected to the corresponding telescopic limiting block 34, and the other end of each spring 35 is movably connected to the inner wall of the second groove 37.

[0044] In this embodiment, before the positions are interchanged, the screw compressor 32 needs to be started to move the inclined block 33. The inclined surface of the inclined block 33 contacts the telescopic limiting block 34, thereby pushing it to slide through the opening 36. After sliding out of the opening 36, the rotor 2 on the rotor mounting shaft 4 is limited, preventing it from detaching from the rotor mounting shaft 4. When it is necessary to push the rotor 2 out, the screw compressor 32 is started to move the inclined block 33 away from the telescopic limiting block 34. Then, under the action of the spring 35, the telescopic limiting block 34 retracts, thereby releasing the limitation on the rotor 2.

[0045] When using the installation auxiliary device for the stator and rotor of a motorcycle magneto according to this embodiment, the rotor 2 is installed on the rotor 2 test rotation unit, and the stator 3 is installed on the stator mounting shaft 5; the rotor 2 test rotation unit is started and moved close to the stator mounting shaft 5, so that the rotor 2 is sleeved on the outside of the stator 3; the rotor 2 is rotated, and it is observed whether the rotor 2 and the stator 3 make contact; if there is no contact, the rotor 2 and the stator 3 are separated, and the position interchange mechanism is activated, so that the rotor mounting shaft 4 is aligned with the rotor 2 test rotation unit, at which time the rotor 2 moves... The magneto housing and end cover are moved to one side of the rotor 2 and the stator 3, respectively, and the lateral movement of the magneto housing and end cover is limited by the upper limit plate 6 and the lower limit plate 7. After the magneto housing and end cover are moved laterally, they move closer to the rotor 2 and the stator 3, and the rotor 2 and the stator 3 are separated from the rotor mounting shaft 4 and the stator mounting shaft 5, respectively. The operator performs bolt fixing operation to install the rotor 2 and the stator 3 on the magneto housing and end cover. The magneto housing and the end cover are then closed and fixed. With the above structural design, a trial run is performed before the stator 3 and the rotor 2 are installed inside the magneto housing and end cover. This ensures that they can operate normally and that the outside of the stator 3 will not come into contact with the rotor 2 before installation. During the installation process, the upper limit plate 6 and the lower limit plate 7 are used to limit the movement path of the magneto end cover and housing, preventing deviation and ensuring that there will be no contact between the stator 3 and the rotor 2 after installation. This significantly improves the assembly qualification rate of the motorcycle magneto.

[0046] Please see Figure 8 The present invention also provides an auxiliary method for installing the stator and rotor of a motorcycle magneto, comprising the following steps: S1: Install the rotor 2 on the rotor 2 test unit, and install the stator 3 on the stator mounting shaft 5; S2: Start the rotor 2 test rotation unit and bring it close to the stator mounting shaft 5 so that the rotor 2 is sleeved on the outside of the stator 3; S3: Rotate the rotor 2 and observe whether the rotor 2 and the stator 3 come into contact; S4: If there is no contact, separate the rotor 2 and the stator 3, activate the position interchange mechanism, so that the rotor mounting shaft 4 is aligned with the rotor 2 test rotation unit, and at this time the rotor 2 is moved and mounted on the rotor mounting shaft 4; S5: The magneto housing and end cover will be moved to one side of the rotor 2 and the stator 3 respectively, and the lateral movement of the magneto housing and end cover will be limited by the upper limit plate 6 and the lower limit plate 7. S6: After the magneto housing and end cover are moved laterally, they approach the rotor 2 and the stator 3, and the rotor 2 and the stator 3 are respectively separated from the rotor mounting shaft 4 and the stator mounting shaft 5; S7: The staff performs bolt fixing operation to install the rotor 2 and the stator 3 on the magneto housing and end cover; S8: Close and fix the magneto housing and the end cap together.

[0047] The rotor 2 is mounted on the rotor 2 test unit, and the stator 3 is mounted on the stator mounting shaft 5. The rotor 2 test unit is then activated and moved closer to the stator mounting shaft 5, so that the rotor 2 is fitted over the stator 3. The rotor 2 rotates, and it is observed whether the rotor 2 and the stator 3 make contact. If there is no contact, the rotor 2 and the stator 3 are separated, and the position interchange mechanism is activated, so that the rotor mounting shaft 4 is aligned with the rotor 2 test unit. At this time, the rotor 2 is moved and mounted on the rotor mounting shaft 4. The magneto housing and end cover are moved to one side of the rotor 2 and the stator 3 respectively, and the lateral movement of the magneto housing and end cover is limited by the upper limit plate 6 and the lower limit plate 7. After the magneto housing and end cover are moved laterally, they are close to the rotor 2 and the stator 3, and the rotor 2 and the stator 3 are respectively separated from the rotor mounting shaft 4 and the stator mounting shaft 5. The operator performs bolt fixing operation to install the rotor 2 and the stator 3 on the magneto housing and end cover. The magneto housing and the end cover are then closed and fixed.
