Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of direct connection range extender assembly, and particularly relates to a horizontal assembly device and method of direct connection range extender. BACKGROUND

[0002] When the direct connection range extender is assembled, the direct connection generator shell is glued and then turned over by 90 degrees, and is directly fixed and connected with the engine. When fixed and connected, the direct connection generator needs to be horizontally assembled with the engine. Before the direct connection generator is horizontally assembled with the engine, the rotor of the direct connection generator is fixed to the rear end crankshaft of the engine, and then the assembly operation of the direct connection generator is performed. The gap between the rotor of the direct connection generator and the stator of the direct connection generator is only 0.6-1mm. Since the rotor of the direct connection generator is provided with a bearing, the direct connection generator is provided with a bearing chamber, and the matching precision of the bearing and the bearing chamber is very high (the matching gap is less than 0.02mm). During the whole horizontal assembly process, it is necessary to ensure that the engine side rotor bearing and the generator side bearing chamber have high centering precision. During the horizontal assembly, the direct connection generator has a downward tilting trend due to the gravity factor. Moreover, the assembly error of the crankshaft of the engine in the height direction is large (about 0.12mm), the assembly size deviation of the engine tray is usually about 0.5mm, and the assembly precision of the horizontal assembly of the direct connection range extender is far lower than the matching precision of the bearing and the bearing chamber, so that the direct connection range extender is easily pressed and damaged during assembly, and the assembly quality is poor. SUMMARY

[0003] The present application aims to provide a horizontal assembly device and method of direct connection range extender, so as to solve the problem of poor assembly quality of the horizontal assembly of the existing horizontal assembly device and method of direct connection range extender.

[0004] To solve the above technical problems, the present application provides a horizontal assembly device of direct connection range extender, characterized in that it comprises an elastic support assembly, a press assembly and a supporting assembly. The supporting assembly is used for mounting the engine provided with the rotor of the direct connection generator. The elastic support assembly is mounted on the press assembly and is used for elastically supporting the stator of the direct connection generator. The press assembly drives the elastic support assembly to move along the first horizontal direction.

[0005] Optionally, the elastic support assembly comprises a bottom plate, a mounting plate, a support guide, an elastic member and a clamping member. The bottom plate is mounted on the press assembly. The support guide is mounted on the bottom plate. The mounting plate is in sliding connection with the support guide. The clamping member is mounted on the mounting plate and is used for clamping the stator of the direct connection generator. The elastic member is located between the bottom plate and the mounting plate and is used for enabling the mounting plate to have a tendency of moving away from the bottom plate.

[0006] Optionally, the elastic support assembly further comprises a guide rod, the guide rod is installed on the bottom plate and is in sliding connection with the mounting plate, the elastic member is a spring, and the spring is sleeved on the guide rod and located between the bottom plate and the mounting plate.

[0007] Optionally, the horizontal assembly device further comprises a vibrator installed on the mounting plate and used for driving the mounting plate to vibrate in the axial direction perpendicular to the support guide.

[0008] Optionally, the horizontal assembly device further comprises a first guide and a second guide, the first guide is installed on the pressing assembly, the second guide is installed on the support assembly, and the first guide has a first state relative to the second guide, in the first state, the pressing assembly drives the stator of the directly-connected generator on the elastic support assembly to slide in the first horizontal direction and drives the first guide to cooperatively slide in the first horizontal direction relative to the second guide.

[0009] Optionally, the support assembly comprises a support component and a tray, the tray is located on the support component, and the tray is used for mounting the engine with the directly-connected generator rotor.

[0010] Optionally, the support assembly further comprises a counterforce component, the counterforce component and the pressing assembly are located on opposite sides of the tray respectively, and the counterforce component is used for supporting the engine with the directly-connected generator rotor in the first horizontal direction.

[0011] The application further provides a method for horizontally assembling the directly-connected range extender, comprising the following steps: mounting the engine with the directly-connected generator rotor on the support assembly; elastically supporting the stator of the directly-connected generator on the elastic support assembly; and driving the elastic support assembly on the pressing assembly to move in the first horizontal direction by the pressing assembly, so as to drive the stator of the directly-connected generator to fold towards the engine with the directly-connected generator rotor in the first horizontal direction.

[0012] Optionally, in the process that the pressing assembly drives the stator of the directly-connected generator on the elastic support assembly to slide in the first horizontal direction, the pressing assembly also drives the first guide to cooperatively slide in the first horizontal direction relative to the second guide, the first guide is installed on the pressing assembly, and the second guide is installed on the support assembly.

[0013] Optionally, the elastic support assembly includes a base plate, a mounting plate, a support guide, an elastic element, and a clamping element. The base plate is mounted on the press-fit assembly, the support guide is mounted on the base plate, the mounting plate is slidably connected to the support guide, and the clamping element is mounted on the mounting plate for clamping the stator of the direct-drive generator. The elastic element is located between the base plate and the mounting plate and is used to make the mounting plate tend to move away from the base plate. The vibrator is mounted on the mounting plate, and when the vibrator is working, it can drive the mounting plate to vibrate in an axial direction perpendicular to the support guide.

[0014] The present invention provides a horizontal assembly device and method for a direct-drive range extender, which has the following beneficial effects: First, since the support assembly is used to mount the rotor of the engine with the direct-drive generator, and the elastic support assembly is mounted on the press-fit assembly, the elastic support assembly is used to elastically support the stator of the direct-drive generator. The press-fit assembly drives the elastic support assembly to move along the first horizontal direction. Therefore, the stator of the direct-drive generator can be horizontally mounted onto the engine with the rotor of the direct-drive generator by the press-fit assembly driving the elastic support assembly to move along the first horizontal direction, thereby realizing the horizontal mounting of the direct-drive range extender. Since the elastic support assembly is used to elastically support the stator of the direct-drive generator, during the horizontal mounting process, the elastic support type can provide thrust, avoiding excessive thrust and lack of buffer space that could cause crush damage between the bearings on the rotor and the bearing housings on the stator, resulting in poor quality of the horizontal mounting of the direct-drive range extender. At the same time, after the horizontal mounting is completed, the stator of the direct-drive generator can be prevented from being pulled back.

[0015] Secondly, by setting up a base plate, mounting plate, support guide, elastic element, and clamping element, a compact and reliable elastic support unit is constructed. The clamping element is used to fix the stator, the mounting plate can slide relative to the base plate to provide floating space for the stator, and the elastic element provides buffering and restoring force, so that the stator can be flexibly buffered when subjected to axial force, thereby accurately controlling the pressing force and preventing rigid impact from damaging precision components.

[0016] Furthermore, the guide rod design enhances the stability of the mounting plate during movement, ensuring its linear motion and preventing stator skewing during assembly. The spring is fitted onto the guide rod, resulting in a simple structure, minimal space occupation, and ensuring the spring force aligns with the direction of movement, thus improving the cushioning effect.

[0017] Then, the vibrator can generate micro-vibrations during the assembly process, and work together with the elastic support of the elastic component to help the stator and rotor of the direct-drive generator automatically fine-tune their alignment before or at the initial stage of contact, overcome static friction and minor jamming, so that the stator and rotor can complete the assembly more smoothly and accurately, further ensuring the assembly requirements of small gaps.

[0018] Subsequently, by setting up a first guide and a second guide, the two slide together at the start of assembly, providing a precise guiding reference for the subsequent closing of the stator and rotor. This effectively compensates for the initial positional deviations of the engine tray, press-fit assembly, etc., ensuring high-precision alignment of the stator and rotor throughout the entire assembly stroke, fundamentally solving the problem of damage caused by large assembly errors. Furthermore, with the function of the first and second guides, the elastic support of the vibrator and elastic components can work together to help the stator and rotor of the direct-drive generator automatically fine-tune their alignment before or at the initial stage of contact, overcoming static friction and minor jamming, allowing the stator and rotor to complete the assembly more smoothly and accurately, further ensuring the assembly requirements of small gaps.

[0019] Finally, when the press-fit assembly pushes the stator to fit the engine, a huge reverse thrust is generated. This thrust could cause the engine itself to shift, leading to assembly failure or equipment damage. The reaction force assembly supports the engine from the other side, effectively balancing the press-fit thrust and ensuring the absolute positional stability of the engine during the assembly process.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] refer to Figure 1 ,Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a three-dimensional structural diagram of the horizontal assembly device for the direct-drive range extender in an embodiment of the present invention. Figure 2 This is a front view structural schematic diagram of the horizontal assembly device for the direct-drive range extender in an embodiment of the present invention. Figure 3 This is a top view of the horizontal assembly device for the direct-drive range extender in an embodiment of the present invention. Figure 4 yes Figure 3 A partial structural diagram of a horizontal assembly device for a direct-drive range extender is shown in this embodiment. The device includes an elastic support assembly 100, a press-fit assembly 200, and a support assembly 300. The support assembly 300 is used to mount an engine with a rotor on which a direct-drive generator is mounted. The elastic support assembly 100 is mounted on the press-fit assembly 200 and is used to elastically support the stator of the direct-drive generator. The press-fit assembly 200 drives the elastic support assembly 100 to move along a first horizontal direction.

[0029] Since the support assembly 300 is used to mount the rotor of the engine with the direct-drive generator, and the elastic support assembly 100 is mounted on the press-fit assembly 200, the elastic support assembly 100 is used to elastically support the stator of the direct-drive generator. The press-fit assembly 200 drives the elastic support assembly 100 to move along a first horizontal direction. Therefore, the press-fit assembly 200 can drive the elastic support assembly 100 to move along the first horizontal direction, thereby horizontally mounting the stator of the direct-drive generator onto the engine with the rotor of the direct-drive generator, thus achieving horizontal mounting of the direct-drive range extender. Since the elastic support assembly 100 is used to elastically support the stator of the direct-drive generator, during the horizontal mounting process, the elastic support type can provide thrust, avoiding excessive thrust and lack of buffer space that could cause crush damage between the bearings on the rotor and the bearing housings on the stator, resulting in poor quality of the horizontal mounting of the direct-drive range extender. Meanwhile, after horizontal assembly is completed, the reset force of the elastic support assembly 100 can prevent the stator of the directly connected generator from being accidentally pulled back, ensuring the reliability of the assembly.

[0030] For details, please refer to Figure 3The elastic support assembly 100 includes a base plate 110, a mounting plate 120, a support guide 130, an elastic element 140, and a clamping element 150. The base plate 110 is mounted on the press-fit assembly 200, the support guide 130 is mounted on the base plate 110, the mounting plate 120 is slidably connected to the support guide 130, the clamping element 150 is mounted on the mounting plate 120 for clamping the stator of the direct-drive generator, and the elastic element 140 is located between the base plate 110 and the mounting plate 120, and is used to make the mounting plate 120 tend to move away from the base plate 110. By setting the base plate 110, mounting plate 120, support guide 130, elastic element 140, and clamping element 150, a compact and reliable elastic support unit is formed. The clamping member 150 is used to fix the stator, the mounting plate 120 can slide relative to the base plate 110 to provide floating space for the stator, and the elastic member 140 provides buffering force and restoring force, so that the stator can be flexibly buffered when subjected to axial force, thereby precisely controlling the pressing force and preventing rigid impact damage to precision components.

[0031] Preferably, the elastic support assembly 100 further includes a guide rod 160, which is mounted on the base plate 110 and slidably connected to the mounting plate 120. The elastic element 140 is a spring, which is sleeved on the guide rod 160 and located between the base plate 110 and the mounting plate 120. The guide rod 160 further enhances the stability of the mounting plate 120 during movement, ensuring its linear movement and preventing the stator from tilting during assembly. Sleeving the spring on the guide rod 160 results in a simple structure, occupies little space, and ensures that the direction of the spring force is consistent with the direction of movement, thus improving the cushioning effect.

[0032] Preferably, the elastic support assembly 100 further includes a limiting member, which is mounted on the support guide 130 and located on the side of the mounting plate 120 away from the base plate 110, to prevent the mounting plate 120 from detaching from the support guide 130. The limiting member effectively prevents the mounting plate 120 from slipping off the support guide 130 due to excessive displacement during movement, improving the safety and reliability of equipment operation.

[0033] Preferably, the horizontal assembly device for the direct-drive range extender further includes a vibrator 180 mounted on the mounting plate 120 and used to drive the mounting plate 120 to vibrate in an axial direction perpendicular to the support guide 130. The vibrator 180 can generate micro-vibrations during the assembly process. The vibration direction is perpendicular to the axial direction of the support guide 130, and the elastic support direction of the elastic element is along the first horizontal direction. Under the combined action of the vibrator 180 and the elastic support of the elastic element 140, the stator and rotor of the direct-drive generator can automatically fine-tune their alignment before or at the initial stage of contact, overcoming static friction and minor jamming, so that the stator and rotor can be assembled more smoothly and accurately, further ensuring the assembly requirements of small gaps.

[0034] The vibrator 180 is preferably a pneumatic vibrator 180. For example, it is a pneumatic steel ball vibrator 180.

[0035] The horizontal assembly device for the direct-drive range extender further includes a first guide 410 and a second guide 420. The first guide 410 is mounted on the press-fit assembly 200, and the second guide 420 is mounted on the support assembly 300. The first guide 410 has a first state relative to the second guide 420: In the first state, the press-fit assembly 200 drives the stator of the direct-drive generator on the elastic support assembly 100 to slide along a first horizontal direction, and drives the first guide 410 to slide relative to the second guide 420 in a first horizontal direction. By setting the first guide 410 and the second guide 420, at the beginning of assembly, the two first slide together, providing a precise guiding reference for the subsequent closing of the stator and rotor. This can effectively compensate for the initial position deviation of the engine tray 320, the press-fit assembly 200, etc., ensuring high-precision alignment of the stator and rotor throughout the entire assembly stroke, fundamentally solving the problem of damage caused by large assembly errors. Furthermore, under the premise of the function of the first guide member 410 and the second guide member 420, the vibrator 180 and the elastic member 140 can work together to help the stator and rotor of the direct-drive generator automatically fine-tune their alignment before or at the beginning of contact, overcome static friction and minor jamming, and enable the stator and rotor to complete the assembly more smoothly and accurately, further ensuring the assembly requirements of small gaps.

[0036] Furthermore, the first guide member 410 has a second state relative to the second guide member 420: in the second state, the first guide member 410 is separated from the second guide member 420. This separation means that after assembly or in a non-working state, the two can be detached, facilitating the flipping or other actions of the press assembly 200, and also facilitating the movement of the pallet 320, thus improving the flexibility of the production line.

[0037] Specifically, the first guide member 410 is a guide post, and the second guide member 420 is a guide sleeve.

[0038] Specifically, the press-fit assembly 200 includes a flipping component 210 and a sliding component 220. The flipping component 210 is mounted on the sliding component 220 and can flip relative to the sliding component 220. The elastic support assembly 100 is mounted on the flipping component 210. The sliding component 220 can move along the first horizontal direction. The first guide member 410 is mounted on the sliding component 220. By dividing the press-fit assembly 200 into the flipping component 210 and the sliding component 220, functional separation is achieved. The sliding component 220 is responsible for horizontal drive, while the flipping component 210 can flip the elastic support assembly 100 and the stator, facilitating the initial vertical loading and gluing operations on the stator, and then flipping it to a horizontal state for assembly, greatly optimizing the assembly process.

[0039] Specifically, the sliding assembly 220 includes a base frame 221, a sliding bracket 222, and a sliding actuator. The sliding bracket 222 is slidably mounted on the base frame 221 along a first horizontal direction. The sliding actuator is mounted on the base frame 221 to drive the sliding bracket 222 to slide. The flipping assembly 210 is mounted on the sliding bracket 222, and the first guide member 410 is mounted on the sliding bracket 222. The specific structure of the sliding assembly 220 (base frame 221, sliding bracket 222, and sliding actuator) provides a stable and reliable linear motion implementation method. The sliding actuator can provide precise and controllable thrust, ensuring the smooth progress of the assembly process.

[0040] The flipping assembly 210 includes a mounting bracket 211 and a rotary actuator 212. The mounting bracket 211 is rotatably mounted on the sliding bracket 222 about a second horizontal direction perpendicular to the first horizontal direction. The rotary actuator 212 is mounted on the sliding bracket 222 to drive the mounting bracket 211 to rotate. The mounting bracket 211 is used to mount the elastic support assembly 100. The specific structure of the flipping assembly 210 (mounting bracket 211, rotary actuator 212) realizes the automatic flipping function of the stator, replacing manual flipping or hoisting flipping, improving efficiency and safety while ensuring precise control of the flipping angle.

[0041] The support assembly 300 includes a support component 310 and a tray 320. The tray 320 is located on the support component 310 and is used to mount an engine with a directly connected generator rotor. Mounting the engine using the support component 310 and the tray 320 makes the engine's load-bearing and positioning more stable and standardized. The tray 320 can be adapted to different engine models, improving the versatility of the device.

[0042] Furthermore, the support assembly 300 also includes a reaction force component 330, which, along with the press-fit assembly 200, is located on opposite sides of the tray 320. The reaction force component 330 supports the engine, on which the rotor of the direct-drive generator is mounted, along a first horizontal direction. The placement of the reaction force component 330 is crucial. When the press-fit assembly 200 pushes the stator to assemble with the engine, a large reverse thrust is generated, which could cause displacement of the engine itself, leading to assembly failure or equipment damage. The reaction force component 330 supports the engine from the other side, effectively balancing the press-fit thrust and ensuring the absolute positional stability of the engine during the assembly process.

[0043] Specifically, the reaction force assembly 330 includes a reaction force support and a reaction force cylinder. The reaction force cylinder is mounted on the reaction force support and is capable of extending and retracting along a first horizontal direction.

[0044] The support assembly 300 also includes a conveyor line 340. The support component 310 is located below the conveyor line 340 and is used to lift the pallet 320 from the conveyor line 340 to a horizontal assembly position and to limit the position of the pallet 320. The combination of the conveyor line 340 and the support component 310 enables automated flow and precise positioning of the engine pallet 320. The support component 310 lifts and limits the pallet 320 from the conveyor line 340, allowing the assembly operation to be carried out in a stable and precise "assembly position". After assembly, the pallet 320 is lowered and can flow out with the line, achieving seamless integration with the automated production line.

[0045] The horizontal assembly device for the direct-drive range extender also includes a displacement sensor 510, which is mounted on the elastic support assembly 100 to monitor the displacement of the elastic support assembly 100. The displacement sensor 510 allows for real-time monitoring of the displacement of the elastic support assembly 100, thereby accurately determining the current position of the stator relative to the rotor. This provides data support for the precise control of the press-fit assembly 200 and the determination of the assembly endpoint, achieving closed-loop control.

[0046] The horizontal assembly device for the direct-drive range extender also includes a pressure sensor 520, which is mounted on the elastic support assembly 100 to monitor the pressure on the elastic support assembly 100. The pressure sensor 520 allows for real-time monitoring of the pressure experienced by the elastic support assembly 100 during assembly. By monitoring pressure changes, abnormal resistance during assembly (such as jamming or misalignment) can be detected promptly, preventing damage caused by forced assembly. It can also be used to determine whether the assembly is in place, ensuring assembly quality.

[0047] This embodiment also provides a method for horizontal assembly using the above-described direct-drive range extender horizontal assembly device, including: The engine with a rotor that is directly connected to the generator is mounted on the support assembly 300; The stator of the directly connected generator is elastically supported on the elastic support assembly 100; The press-fit assembly 200 drives the elastic support assembly 100 mounted on the press-fit assembly 200 to move along a first horizontal direction, thereby driving the stator of the direct-drive generator to close along the first horizontal direction toward the engine on which the rotor of the direct-drive generator is mounted.

[0048] This method involves horizontally pressing the stator after it is elastically supported, which provides flexible buffering for the entire assembly process, effectively absorbing assembly errors and avoiding rigid impacts, thereby achieving high-quality and high-precision horizontal assembly of the direct-drive range extender.

[0049] Preferably, during the sliding of the stator of the direct-drive generator on the elastic support assembly 100 by the press-fit assembly 200 along the first horizontal direction, the press-fit assembly 200 also drives the first guide member 410 to slide relative to the second guide member 420 along the first horizontal direction. The first guide member 410 is mounted on the press-fit assembly 200, and the second guide member 420 is mounted on the support assembly 300. This method introduces precise guidance during assembly. Through the cooperation of the first guide member 410 and the second guide member 420, it ensures that the stator maintains precise alignment with the engine rotor throughout its entire stroke, greatly improving the success rate and reliability of the assembly.

[0050] Specifically, the elastic support assembly 100 includes a base plate 110, a mounting plate 120, a support guide 130, an elastic element 140, and a clamping element 150. The base plate 110 is mounted on the press-fit assembly 200, the support guide 130 is mounted on the base plate 110, the mounting plate 120 is slidably connected to the support guide 130, and the clamping element 150 is mounted on the mounting plate 120 for clamping the stator of the direct-drive generator. The elastic element 140 is located between the base plate 110 and the mounting plate 120 and is used to make the mounting plate 120 tend to move away from the base plate 110. The vibrator 180 is mounted on the mounting plate 120. When the vibrator 180 is working, it can drive the mounting plate 120 to vibrate in an axial direction perpendicular to the support guide 130. This method adds a vibration-assisted centering step to the elastic support. During the process of the stator closing with the rotor, especially when they are close to contact, vibration can cause the stator to automatically seek its own position, overcome minor misalignment forces and friction, and achieve "self-adaptive" precise alignment, which further ensures the assembly quality of the high-precision fit between the bearing and the bearing housing.
