Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and in particular to a flexible compensation mechanism for a motor stator and rotor assembly and alignment device. Background Technology

[0002] Electric motors are widely used in industry and daily life, and the stator and rotor, as the core components of a motor, are crucial for ensuring efficient and stable operation through precise assembly. Traditional stator-rotor assembly is done manually, which is difficult and inefficient for large motors. It relies entirely on worker experience and lacks guaranteed assembly precision, potentially leading to scratches between the stator and rotor, and making it impossible to determine the final product quality. To improve production efficiency, reduce labor costs, and ensure consistent product quality, many motor manufacturers are now using stator-rotor assembly equipment.

[0003] To ensure the coaxiality of the stator and rotor axes, two sets of alignment devices need to be installed on the assembly equipment to detect the center position of the stator's two end stops, thereby achieving precise measurement of the offset of the stator's virtual central axis. The key and challenging aspect of stator-rotor assembly lies in the need for precise measurement and adjustment of the stator-rotor coaxiality before assembly. Due to the assembly process and equipment structure, the shaft deviation measuring mechanism maintains a certain distance from the stator being measured. During measurement, it extends to the stator end face and retracts after measurement, leaving sufficient space for assembly. Therefore, the measuring head of the measuring mechanism will experience a certain amount of deformation, exceeding the allowable measurement error and affecting measurement accuracy. To ensure that the measuring mechanism of the alignment device can move to the end cover mounting face of different motor models, the moving stroke of the alignment device's moving mechanism is relatively long. The flexible deformation generated by the overall device will affect the alignment accuracy of the stator and rotor in the assembly equipment.

[0004] Therefore, it is necessary to provide a flexible compensation mechanism for a motor stator and rotor assembly alignment device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The main objective of this invention is to provide a flexible compensation mechanism for a motor stator and rotor assembly alignment device, which aims to solve the technical problem that the flexible deformation generated during the assembly operation of existing assembly equipment affects the alignment accuracy of the stator and rotor of the assembly equipment.

[0006] To achieve the above objectives, the flexible compensation mechanism for a motor stator-rotor assembly alignment device of the present invention comprises a fixed base frame, a lead screw drive component, an alignment moving component, and an alignment measuring component. The flexible compensation mechanism includes a support component and a gravity sensing component. The gravity sensing component is mounted on the fixed base frame. The alignment moving component includes a base plate and a moving frame. The base plate is mounted on the gravity sensing component, and the moving frame is slidably mounted on the base plate. The lead screw drive component is mounted on the base plate and connected to the moving frame. The alignment measuring component and the support component are mounted on the moving frame. The fixed base frame includes a central shaft whose axial direction is aligned with the sliding direction of the moving frame. The support component supports the moving frame on the central shaft after sliding. The gravity sensing component measures the load under flexible deformation. The gravity sensing component and the support component work together to form the flexible compensation mechanism, realizing flexible compensation of the overall alignment device.

[0007] A further improvement of the flexible compensation mechanism for the motor stator and rotor assembly alignment device of the present invention is that the gravity sensing component includes a hinged shaft system and a tension / compression sensor. The hinged shaft system is located on the side away from the alignment measuring component, and the tension / compression sensor is located on the side close to the alignment measuring component. The hinged shaft system is used to rotatably connect the fixed base frame and the base plate, and the tension / compression sensor is used to measure the load under the flexible deformation state.

[0008] A further improvement of the flexible compensation mechanism for the motor stator and rotor assembly alignment device of the present invention is that the hinge shaft system includes a connecting shaft, a bearing housing, and a connecting seat. The bearing housing is mounted on the fixed base frame, the connecting seat is mounted on the bottom surface of the base plate, and the connecting shaft connects the bearing housing and the connecting seat.

[0009] A further improvement of the flexible compensation mechanism for the motor stator and rotor assembly alignment device of the present invention is that the hinge shaft system further includes a needle roller bearing and a limiting bolt, the needle roller bearing being installed between the bearing housing and the connecting shaft, and the limiting bolt being connected to the connecting shaft.

[0010] A further improvement of the flexible compensation mechanism for the motor stator-rotor assembly alignment device of the present invention lies in that the load under the flexible deformation state measured by the tension / compression sensor is... The length of the sliding extension of the base plate of the movable frame The relationship between them can be expressed by the following flexible equation: ; ; in: for Formula for the amount of flexible deformation at a location; The Young's modulus of the material; The moment of inertia of the cross section; The total length of the entire centering moving component and the components mounted on it extending outwards; This refers to the distance between the moving component and the fixed end. This refers to the amount of flexible deformation generated at the end position of the moving component away from the fixed end. The total weight of the end structure of the component mounted on the moving component that is furthest from the fixed end; This is the acceleration due to gravity.

[0011] A further improvement of the flexible compensation mechanism for the motor stator and rotor assembly alignment device of the present invention is that the support member includes a drive assembly, a roller and a guide frame, the guide frame is mounted on the movable frame, the drive assembly is mounted on the guide frame, the roller is mounted on the bottom of the guide frame, and the drive assembly is used to drive the roller to support the central shaft.

[0012] A further improvement of the flexible compensation mechanism for the motor stator and rotor assembly alignment device of the present invention is that the guide frame includes a fixed plate, a mounting plate, a drive shaft and a guide shaft. The fixed plate is mounted on the guide frame, the drive shaft and the guide shaft are slidably mounted on the fixed plate, the mounting plate is mounted on the bottom end of the guide shaft and the drive shaft, and the drive assembly is drivenly connected to the drive shaft.

[0013] A further improvement of the flexible compensation mechanism for the motor stator and rotor assembly alignment device of the present invention is that the alignment measuring component includes a probe for detecting the center position of the motor stator and rotor.

[0014] A further improvement of the flexible compensation mechanism for the motor stator and rotor assembly alignment device of the present invention is that a slide rail is mounted on the base plate, and a slider that cooperates with the slide rail is provided on the movable frame.

[0015] A further improvement of the flexible compensation mechanism for the motor stator and rotor assembly alignment device of the present invention is that the bottom of the fixed base is provided with a traveling support, and one end of the central shaft is fixed to the traveling support.

[0016] The technical solution of the present invention has the following beneficial effects: The flexible compensation mechanism for a motor stator and rotor assembly alignment device provided by this invention, through the combination of a support component and a gravity sensing component, compensates for the deformation of the overall structure, ensuring alignment measurement accuracy. The support component prevents the entire moving frame from "drooping" or experiencing excessive vertical deformation, and the readings of tension and compression sensors determine whether the entire moving frame remains horizontal. Dynamic flexible deformation compensation is achieved, ensuring that the vertical coordinates of the measuring head of the corresponding measuring mechanism remain consistent under different displacement conditions. This invention achieves automatic compensation for the flexible deformation of the measuring mechanism. The drive component controls the downward movement of the support device, and the tension and compression sensors provide feedback on the support status of the support device, determining whether the vertical position of the measuring head has been fully compensated. This achieves precise control of the flexible compensation amount of the structure, ensuring the precision of motor assembly and providing a reliable flexible compensation solution for the precision control of motor measuring devices. It solves the technical problem that the flexible deformation generated during assembly operations in existing assembly equipment affects the alignment accuracy of the stator and rotor.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0024] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0025] like Figures 1-7 As shown, this invention proposes a flexible compensation mechanism for a motor stator and rotor assembly alignment device. The assembly alignment device includes a fixed base frame 1, a lead screw transmission component 2, an alignment moving component 3, and an alignment measuring component 5. The flexible compensation mechanism includes a support component 6 and a gravity sensing component 7. The gravity sensing component 7 is mounted on the fixed base frame 1. The alignment moving component 3 includes a base plate 301 and a moving frame 302. The base plate 301 is mounted on the gravity sensing component 7, and the moving frame 302 is slidably mounted on the base plate 301. The lead screw transmission component 2 is mounted on the base plate 301, and the moving frame 302 is connected to the lead screw transmission component 2. The alignment measuring component 5 and the support component 6 are mounted on the moving frame 302. The fixed base frame 1 includes a central shaft 102 whose axial direction is consistent with the sliding direction of the moving frame 302. The support component 6 is used to support the moving frame 302 on the central shaft 102 after it slides. The gravity sensing component 7 is used to measure the load under flexible deformation.

[0026] This invention uses a support device and a pressure sensor to feed back the amount of flexural deformation, ensuring that the entire centering moving component 3 remains horizontal. This achieves flexural compensation at the position of the probe 501, preventing scraping between the stator and rotor during motor assembly due to insufficient centering accuracy. It provides a stable, reliable, and efficient inspection guarantee for motor assembly quality, solves the problem of uncontrollable parameters affecting measurement accuracy, and improves the centering measurement accuracy of motor assembly.

[0027] Specifically, the lead screw transmission component 2 includes a lead screw nut and a lead screw. The lead screw nut is connected to the movable frame 302 by bolts. The lead screw nut is screwed onto the lead screw. The lead screw is driven to rotate by a motor, and the lead screw nut moves left and right on the lead screw, providing power for the movement of the movable frame 302.

[0028] Furthermore, such as Figure 3 and Figure 4As shown, the gravity sensing component 7 includes a hinged shaft system 4 and a tension / compression sensor 705. The hinged shaft system 4 is located on the side away from the centering measuring component 5, and the tension / compression sensor 705 is located on the side closer to the centering measuring component 5. The hinged shaft system 4 is used to rotatably connect the fixed base frame 1 and the base plate 301, and the tension / compression sensor 705 is used to measure the load under flexible deformation. In this embodiment, there are two tension / compression sensors 705, which are installed at intervals on the side closer to the centering measuring component 5. To avoid excessive difference in pressure values ​​between the left and right tension / compression sensors 705 due to structural factors, a rigid connection is not used between the sensor and the base plate 301. Instead, a ball-head contactor 706 is used. This ball-head structure ensures that the load on the tension / compression sensor 705 is uniform, avoiding discrepancies between the pressure value and the actual situation due to installation or other reasons.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, the hinged shaft system 4 includes a connecting shaft 701, a bearing housing 702, and a connecting seat 707. The bearing housing 702 is mounted on the fixed base frame 1, and the connecting seat 707 is mounted on the bottom surface of the base plate 301. The connecting shaft 701 connects the bearing housing 702 and the connecting seat 707, realizing the connection between the centering and centering moving component 3 and the fixed base frame 1. In this embodiment, there are two bearing housings 702 and two connecting seats 707, which are respectively installed at both ends of the connecting shaft 701. The hinged shaft system 4 is completely symmetrical. The connecting shaft 701 and the connecting seat 707 have an interference fit with a large amount of interference to ensure that there is no relative rotation between them. To ensure structural compactness, a needle roller bearing 703 is selected. The connecting shaft 701 and the needle roller bearing 703 also have an interference fit, but a smaller amount of interference is selected. This fit relationship can ensure that there is no clearance between the bearing and the hinged shaft and facilitates installation.

[0030] Preferably, the hinged shaft system 4 further includes a needle roller bearing 703 and a limiting bolt 704. The needle roller bearing 703 is installed between the bearing housing 702 and the connecting shaft 701, and the limiting bolt 704 is connected to the connecting shaft 701. The fixed base 1 is provided with a mounting block for screwing the limiting bolt 704. In this embodiment, there are two limiting bolts 704, which are screwed onto both ends of the connecting shaft 701 respectively to ensure that the connecting shaft 701 does not move axially.

[0031] like Figure 5 As shown, when the movable frame 302 extends, the end of the tension / compression sensor 705 is compressed, causing the components above the gravity sensing component 7 to rotate at a small angle around the hinge axis 4. When there is no supporting component 6, the entire structure undergoes flexible deformation under gravity, causing a vertical displacement of the measuring head position. This displacement occurs as the movable frame 302 extends beyond the base plate 301. The larger the value, the greater the vertical displacement. If the weight of other parts is ignored, and the moving frame 302 is considered to have only the main weight at its ends, then the overall schematic diagram is as follows: Figure 5 As shown, according to the following formula, we can obtain... and The relationship between the two is as follows: the greater the load on the tension / compression sensor 705, the greater the pressure reading of the corresponding pressure sensor. Ideally, the vertical displacement at different extension lengths can be calculated using a simplified model, thereby compensating for the vertical displacement of the probe 501 at the end. However, the vertical displacement caused by two factors cannot be predicted: one is the vertical displacement caused by the gap between the guide rail and the slider, and the other is the plastic deformation caused by long-term deformation, which cannot be confirmed. Therefore, a support member 6 is introduced at the end.

[0032] The tensile / compressive sensor 705 measures the load under flexural deformation. The length of the sliding extension of the movable frame 302 beyond the base plate 301 The relationship between them can be expressed by the following flexible equation: ; ; in: for Formula for the amount of flexible deformation at a location; The Young's modulus of the material; The moment of inertia of the cross section; The total length of the entire centering moving component (specifically the moving frame of the centering moving component) and the components mounted on it extending outwards; This refers to the distance between the centering moving component (specifically, the moving frame of the centering moving component) and the fixed end; The amount of flexible deformation generated at the end position of the centering moving component (specifically the moving frame of the centering moving component) away from the fixed end; The total weight of the end structure of the component mounted on the centering moving component (specifically the base plate) away from the fixed end; This is the acceleration due to gravity.

[0033] Specifically, such as Figure 6 and Figure 7As shown, the support member 6 includes a drive assembly, a roller 601, and a guide frame. The guide frame is mounted on the movable frame 302, the drive assembly is mounted on the guide frame, and the roller 601 is mounted on the bottom of the guide frame. The drive assembly drives the roller 601 to support the central shaft 102. In this embodiment, the roller 601 is made of rubber to reduce damage to the central shaft 102. The drive assembly includes a motor 606 and a turbine lift 607. The motor 606 is driven and connected to the turbine lift 607, and the turbine lift 607 is driven and connected to the guide frame to achieve vertical displacement of the roller 601. By introducing a retractable support member 6 outside the center of gravity of the centering measuring member 5, the problem of flexible deformation during measurement can be solved, and the mechanism can be retracted before assembly, leaving space for assembly operation.

[0034] Preferably, the guide frame includes a fixed plate 602, a mounting plate 603, a drive shaft 604, and a guide shaft 605. The fixed plate 602 is mounted on the guide frame, the drive shaft 604 and the guide shaft 605 are slidably mounted on the fixed plate 602, the mounting plate 603 is mounted on the bottom end of the guide shaft 605 and the drive shaft 604, and the drive assembly is driven and connected to the drive shaft 604. The turbine lift 607 is driven and connected to the drive shaft 604. When the movable frame 302 extends to its position, the motor 606 drives the lower roller 601 to contact the central shaft 102, such as... Figure 5 As shown, the load on the tension / compression sensor 705 changes. As the roller 601 continues to move downwards, the sensor reading gradually decreases. When the load on the pressure sensor reaches a preset value, it is assumed that the moving frame 302, under the action of the support member 6, maintains a horizontal state, thereby achieving flexibility compensation for the position of the measuring pen. In this embodiment, a linear bearing 608 is provided on the guide shaft 605 to reduce sliding friction.

[0035] Preferably, the centering measurement component 5 includes a probe 501 for detecting the center position of the motor stator and rotor. The probe 501 is the main functional component of the measurement mechanism, and the core component is a micro-motion sensor.

[0036] Furthermore, a slide rail is installed on the base plate 301, and a slider is provided on the movable frame 302 to cooperate with the slide rail, so as to realize the sliding installation of the movable frame 302. The overall center of gravity of the structure above the gravity sensing component 7 needs to be adjusted by counterweights to make the center of gravity located at... Figure 1The support member 6 shown is positioned to the left to ensure that the flexible compensation achieves the expected goal. The preset value of the tension / compression sensor 705 can be obtained by calculating the center of gravity of the overall structure and the sensor position. However, since the gap between the slider and the guide rail is unknown, the calculated value may deviate from the pressure value required in actual application. Therefore, in actual use, the actual measurement results of the centering measuring member 5 are used to assess the impact on the quality of the stator and rotor assembly. After reverse calculation, it is determined whether the preset value of the tension / compression sensor 705 needs to be adjusted to further ensure the compensation accuracy of the flexible compensation mechanism of the centering device, thereby ensuring the measurement progress of the centering measuring member 5 and ultimately ensuring the quality of the stator and rotor assembly. This invention considers both structural elastic deformation and displacement caused by slider gap, eliminating the influence of uncontrollable parameter changes on measurement accuracy.

[0037] Preferably, the bottom of the fixed base frame 1 is provided with a traveling support 101, and one end of the central shaft 102 is fixed to the traveling support 101. The traveling support 101 and the central shaft 102 are auxiliary components that are assembled together, and the entire centering device is mounted on the traveling support 101. The fixed base frame 1 serves as the bottom support for the entire centering device, realizing the connection with the traveling support.

[0038] When assembling the motor stator and rotor, the movable frame 302 is driven to extend out of the base plate 301 via the lead screw transmission component 2, such as... Figure 1 As shown by the dashed line, the center of gravity of the device moves beyond the support point. Due to the flexural deformation, the front end of the centering measuring component 5 undergoes a vertically downward elastic deformation. The moving frame 302 and the base plate 301 are connected by a guide rail and slider assembly. Because the fit between the guide rail and slider is a clearance fit, when the moving mechanism extends, the fit between the guide rail and slider changes from a pre-loaded tight fit to a stretched state, creating a gap between them. Under the combined effect of structural elastic deformation and component gaps, the position of the probe 501 of the centering measuring component 5 exhibits deformation uncertainty. Therefore, a support component 6 and a gravity sensing component 7 are used in combination to compensate for the deformation of the overall structure and ensure the accuracy of the centering measurement.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the protection scope of the present invention.
