Description

Technical Field

[0001] This invention relates to the field of motor core processing technology, specifically a high-efficiency motor stator core chamfering and end face synchronous processing device. Background Technology

[0002] As a key power device widely used in industrial production, daily life, and many high-tech fields, the quality of the core components of an electric motor directly affects its operating performance and service life. The stator core, as a crucial component of the motor's magnetic circuit, plays a vital role in the assembly and use of the motor. Chamfering the stator core facilitates easier assembly onto the motor shaft, effectively preventing scratches and jamming during assembly. Chamfering also eliminates burrs on the core edges, reducing noise and wear during operation. Furthermore, the machining accuracy of the stator core end faces directly affects the tightness of the fit between the core and the motor housing. Fine machining of the end faces results in higher flatness, ensuring precise positioning and stable installation of the core within the motor housing. This is crucial for guaranteeing the motor's coaxiality and smooth operation. Therefore, before the formal assembly of the motor stator core, necessary mechanical processing must be performed on the end faces and chamfered areas of the core.

[0003] A specific number of silicon steel laminations are stacked to form the stator and rotor cores of a motor. The inner and outer diameters of the rotor core cross-section and the outer diameter of the rotor end face all require chamfering. Designing dedicated chamfering equipment can significantly improve efficiency and accuracy, reduce tooling and clamping time, and minimize the use of high-value general-purpose machine tools. However, currently, in the field of motor stator core processing, there is a lack of dedicated automated processing equipment for chamfering and end-face machining. Existing processing methods mainly rely on traditional lathes or milling machines. While these general-purpose machine tools can meet basic processing needs for small-sized, lightweight stator cores, their limitations become apparent for larger, heavier stator cores. First, when chamfering large-sized cores, traditional milling machines struggle to maintain clamping stability due to the core's weight, leading to vibration and displacement during processing, making it difficult to control the chamfering accuracy and resulting in inconsistent processing quality. Second, traditional processing equipment lacks flexible processing position adjustment mechanisms, making it impossible to quickly adjust processing parameters according to different stator core sizes, resulting in poor versatility. Meanwhile, chamfering and end-face processing usually require two separate processes. This fragmented process leads to low overall processing efficiency, high manual labor intensity, and high production costs. Summary of the Invention

[0004] This invention provides a high-efficiency device for simultaneous chamfering and end-face processing of motor stator cores, solving the technical problems of existing technologies that cannot achieve simultaneous chamfering and end-face processing of large-size, high-mass stator cores, resulting in low processing accuracy and poor stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-efficiency synchronous processing device for chamfering and end face of motor stator core includes a processing table. A synchronous processing component is set on the processing table. The synchronous processing component includes a rotating disk. A chamfering processing component and an end face processing component are set on the rotating disk. The rotation of the rotating disk enables the chamfering and end face processing components to process and shape the end face and chamfer of the stator core. A material gripping component is set on one side of the processing table. The material gripping component is used to grip the stator core and move it above the synchronous processing component to cooperate with the synchronous processing component to synchronously process the chamfer and end face of the stator core.

[0007] As a preferred embodiment of the present invention, the synchronous processing component includes a processing groove formed on a processing table, a fixed column fixedly connected to the processing groove, a limiting platform fixedly sleeved at the top of the fixed column for fixing and limiting the stator core, and a fixed plate fixedly sleeved on the fixed column below the limiting platform.

[0008] As a preferred embodiment of the present invention, the side wall of the limiting platform is fixedly connected to a limiting protrusion, which is engaged with the stator core to prevent the stator core from rotating during processing.

[0009] As a preferred embodiment of the present invention, the chamfering assembly includes a mounting block disposed on a rotating disk, and a chamfering tool is fixedly connected to the mounting block, wherein one side of the top end of the chamfering tool has an arc surface structure.

[0010] As a preferred embodiment of the present invention, the end face processing assembly includes a mounting bracket disposed on a rotating disk, and an end face processing cutter is fixedly connected to the mounting bracket, wherein the top end of the end face processing cutter has a flat cutter structure.

[0011] As a preferred embodiment of the present invention, a lifting assembly is provided between the mounting frame and the mounting block and the rotating disk. The lifting assembly is used to drive the mounting frame or the mounting block to move up and down, and to adjust the processing height of the end face processing tool and the chamfering processing tool, so that the tools can adapt to stator cores of different thicknesses or different processing depths.

[0012] As a preferred embodiment of the present invention, a driven pulley is rotatably mounted on a fixed column below the rotating disk, and the driven pulley is fixedly connected to the rotating disk.

[0013] In a preferred embodiment of the present invention, a mounting slot is provided within the machining table. A drive motor is fixedly connected to one side of the machining table within the mounting slot. A drive pulley is fixedly mounted on the output shaft of the drive motor. A transmission belt is provided between the drive pulley and the driven pulley, and the drive pulley and the driven pulley are connected by the transmission belt. A switch panel is provided on the side wall of the machining table for controlling the start and stop of the drive motor. After the drive motor starts, power is transmitted to the driven pulley through the transmission belt, thereby driving the rotating disk and its chamfering and end-face machining tools to rotate synchronously.

[0014] As a preferred embodiment of the present invention, a limiting groove is provided on the processing table surface above the processing groove, and a movable annular baffle is provided in the limiting groove to prevent iron filings from flying during the processing, thereby playing a safety protection role.

[0015] As a preferred embodiment of the present invention, the material gripping assembly includes a robotic arm, the output end of which is provided with grippers for gripping stator cores.

[0016] This invention offers the following advantages: By setting up a synchronous processing component, the chamfering and end-face processing components are simultaneously carried by a rotating disk, enabling simultaneous processing of the stator core's chamfers and end faces. This significantly improves processing efficiency and saves considerable time compared to the traditional method of processing one process at a time. By using a limiting stage and limiting protrusions to fix and limit the stator core, combined with a drive motor that rotates the rotating disk via belt drive, a processing mode where the workpiece is stationary and the tool rotates is achieved. This results in high processing stability and is particularly suitable for processing large-size, high-mass stator cores, effectively solving the problem of poor stability when processing large-mass stator cores using traditional milling machines.

[0017] By setting an adjustable-height cutting tool and adjusting the tool's machining radius through sliding adjustment of the mounting block and mounting bracket relative to the diameter of the rotating disk, this device can adapt to the machining needs of stator cores of different sizes and specifications, making it flexible and versatile. The inclusion of a replaceable limit stage and adjustable tool position further enhances the device's applicability; the appropriate limit stage can be replaced according to the actual size of the core being machined, or the tool position can be adjusted to meet different machining requirements.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] like Figures 1 to 8As shown, the high-efficiency motor stator core chamfering and end face synchronous processing device of this invention has a modular structure design, mainly including a processing table 1, a synchronous processing component 4 set on the processing table 1, and a material gripping component set on one side of the processing table 1. The processing table 1 has a box-like structure design. The bottom of the processing table 1 is provided with multiple support feet to stably support the entire device on the ground. The height of the support feet can be adjusted according to the actual workshop floor conditions to ensure that the processing table 1 is in a horizontal state, providing a basic guarantee for subsequent precise positioning processing. A switch panel 7 is provided on the side wall of the processing table 1. The switch panel 7 is electrically connected to the drive motor 413 set inside the processing table 1. The operator can control the start and stop of the drive motor 413 through the buttons or knobs on the switch panel 7, thereby realizing the control of the entire synchronous processing process. An emergency stop button is also provided on the switch panel 7. In case of emergency, the operator can quickly press the emergency stop button to cut off the power supply to the drive motor 413 to ensure the safety of the equipment and the operator.

[0029] The synchronous processing component 4 is a core component of this invention, used to achieve simultaneous processing and forming of the stator core chamfers and end faces. For example... Figures 3-8As shown, a machining groove 8 is formed on the surface of the machining table 1. The machining groove 8 has a circular structure, and its diameter is larger than the outer diameter of the fixing column 412 that needs to be installed later. The depth of the machining groove 8 is determined according to the actual design requirements to ensure that the fixing column 412 can be stably installed in the machining groove 8. The fixing column 412 is fixedly connected to the bottom of the machining groove 8. The fixing column 412 is set in the vertical direction, and its lower end is fixedly connected to the bottom of the machining groove 8 by welding or bolting. The top of the fixing column 412 extends upward to the surface of the machining table 1. A limiting platform 401 is fixedly sleeved on the top of the fixed column 412. The limiting platform 401 has a frustum-shaped structure and a through hole in its center that matches the top of the fixed column 412. The limiting platform 401 is fixedly sleeved on the top of the fixed column 412 through the through hole. The outer diameter of the limiting platform 401 matches the inner diameter of the stator core to be processed. When the stator core needs to be processed, the stator core is sleeved on the limiting platform 401. The limiting platform 401 plays a role in positioning and supporting the stator core. The side wall of the limiting stage 401 is fixedly connected with limiting protrusions 408. There are multiple limiting protrusions 408, which are evenly distributed along the circumference of the limiting stage 401. The shape of the limiting protrusions 408 matches the groove structure on the side wall of the stator core. When the stator core is sleeved on the limiting stage 401, the limiting protrusions 408 are embedded in the groove of the stator core to achieve circumferential positioning of the stator core. This prevents the stator core from shifting with the rotation of the tool during processing, ensuring the stability and accuracy of the processing. A fixing plate 402 is fixedly sleeved on the fixing column 412 below the limiting platform 401. The fixing plate 402 is located below the limiting platform 401 and maintains a certain axial distance from the limiting platform 401. Together, they form a double support and positioning structure for the stator core. The outer diameter of the fixing plate 402 is slightly larger than the outer diameter of the limiting platform 401. It is used to provide bottom support for the stator core sleeved on the limiting platform 401 to prevent the stator core from falling downward during processing.

[0030] The rotating disk 403 has a disc-shaped structure, with a diameter slightly larger than the outer diameter of the largest stator core, to ensure that the chamfering tool 404 and the end-face tool 407 can cover the entire machining area of ​​the stator core. The rotating disk 403 is connected to the fixed column 412 via bearings, allowing the rotating disk 403 to rotate around the axis of the fixed column 412. A driven pulley 414 is rotatably mounted on the fixed column 412 below the rotating disk 403. The driven pulley 414 is fixedly connected to the rotating disk 403 via a key connection or interference fit, and rotates together with the rotating disk 403. The machining table 1 has an internal mounting slot 411 for accommodating the drive motor 413 and the main components of the transmission system. The drive motor 413 is fixedly mounted on the inner wall of the machining table 1 on one side of the mounting slot 411 via bolts. The output shaft of the drive motor 413 is horizontally arranged, and its axis is parallel to the axis of the fixed column 412. A drive pulley 409 is fixedly fitted onto the output shaft of the drive motor 413. A transmission belt 410 is provided between the drive pulley 409 and the driven pulley 414. The tension of the transmission belt 410 can be adjusted by a tensioning wheel adjustment device to ensure no slippage during transmission. After the drive motor 413 starts, it transmits power to the driven pulley 414 via the transmission belt 410, thereby driving the rotating disk 403 to rotate. The transmission ratio between the drive pulley 409 and the driven pulley 414 is 1:1 or can be set to other transmission ratios as needed to meet different machining speed requirements.

[0031] Both the chamfering assembly and the end-face machining assembly are mounted on the rotating disk 403. They rotate synchronously under the drive of the rotating disk 403, achieving simultaneous chamfering and end-face machining of the stator core. The chamfering assembly includes a mounting block 405 mounted on the rotating disk 403 and a chamfering cutter 404 fixedly connected to the mounting block 405. The mounting block 405 is fixed to the upper surface of the rotating disk 403 by bolts. The bottom of the mounting block 405 has a positioning step that matches the upper surface of the rotating disk 403, ensuring the accuracy of the mounting block 405's installation position. The chamfering cutter 404 is fixedly mounted on the top side of the mounting block 405. One of its top edges is designed with an arc surface structure, which matches the chamfer contour of the stator core. When the chamfering cutter 404 rotates, the arc surface structure contacts and cuts the edge of the stator core, forming a chamfer shape that meets the design requirements. The end-face machining assembly includes a mounting bracket 406 mounted on a rotating disk 403 and an end-face machining cutter 407 fixedly connected to the mounting bracket 406. The mounting bracket 406 is also fixed to the upper surface of the rotating disk 403 by bolts. The mounting bracket 406 and the mounting block 405 are arranged at intervals along the circumference of the rotating disk 403, and the distance between them can be adjusted according to the size of the stator core to be machined. The end-face machining cutter 407 is fixedly mounted on the top side of the mounting bracket 406. Its top is set as a flat cutter structure. The width and cutting edge angle of the flat cutter structure are designed according to the depth of end-face machining and surface quality requirements. When the end-face machining cutter 407 rotates, the flat cutter structure contacts the end face of the stator core and mills it flat, removing burrs and uneven areas from the end face and improving the flatness and surface roughness of the end face.

[0032] In another embodiment of the present invention, a lifting assembly is provided between the mounting frame 406 and the mounting block 405 and the rotating disk 403. The lifting assembly is used to drive the mounting frame 406 or the mounting block 405 to move up and down in the vertical direction, so as to adjust the processing height of the end face processing tool 407 and the chamfering processing tool 404, so that the tools can adapt to stator cores of different thicknesses or different processing depths. The specific structure of the lifting assembly can be a cylinder driven structure, a hydraulic cylinder driven structure, or a screw and nut transmission structure. Taking the screw and nut transmission structure as an example, the lifting assembly includes a lifting screw and a lifting nut. The lifting screw is vertically arranged and its two ends are supported on the rotating disk 403 through bearing seats. The lifting nut is threaded with the lifting screw and fixedly connected to the bottom of the mounting block 405 or the mounting frame 406. When the lifting screw is rotated, the lifting nut drives the mounting block 405 or the mounting frame 406 to move up and down, thereby adjusting the vertical position of the chamfering processing tool 404 or the end face processing tool 407. The lifting screw is equipped with scale markings, allowing operators to precisely adjust the cutting tool's machining height according to the thickness of the stator core to be processed and the machining requirements. In addition to the lifting adjustment function, the mounting block 405 and mounting bracket 406 can also slide relative to the diameter of the rotating disk 403 to adjust the cutting tool's machining radius, adapting to the machining needs of stator cores with different diameters. Guide sliders are located at the bottom of the mounting block 405 and mounting bracket 406, and a guide rail matching the guide slider is located on the upper surface of the rotating disk 403. The guide slider is embedded in the guide rail and can slide along it. The guide rail is arranged along the diameter of the rotating disk 403. By adjusting the position of the mounting block 405 and mounting bracket 406 along the guide rail, the distance between the chamfering tool 404 and the end-face machining tool 407 and the axis of the fixed column 412 can be changed, thereby enabling the machining of stator cores with different diameters. Through the cooperation of the lifting assembly and radial sliding adjustment, this device achieves universal machining of stator cores of different sizes.

[0033] A limiting groove 6 is provided on the surface of the machining table 1 above the machining groove 8. The limiting groove 6 surrounds the machining groove 8 and is used to accommodate a movable annular baffle 5. The annular baffle 5 has a circular structure, with its inner diameter slightly larger than the outer diameter of the limiting table 401 and its outer diameter slightly larger than the inner diameter of the limiting groove 6. The annular baffle 5 is placed in the limiting groove 6 and can move circumferentially along the limiting groove 6. The height of the annular baffle 5 is higher than the surface of the machining table 1. During the machining process, the annular baffle 5 is used to shield the flying iron filings, preventing them from scattering and injuring the operators. At the same time, the annular baffle 5 can also collect the iron filings generated during the machining process, facilitating subsequent cleaning.

[0034] The gripping assembly is located on one side of the processing table 1 and is used to grip the stator core and move it above the synchronous processing assembly 4. Together with the synchronous processing assembly 4, it completes the synchronous processing of the stator core's chamfering and end face. The gripping assembly includes a robotic arm 2 and a gripper 3 located at the output end of the robotic arm 2. The robotic arm 2 adopts a multi-joint industrial robot structure with multiple rotary joints and degrees of freedom, enabling flexible movement in three-dimensional space to achieve precise gripping and positioning of the stator core. The gripper 3 is located at the output end of the robotic arm 2. The gripper 3 can be a pneumatic gripper, a hydraulic gripper, or an electric gripper. The gripper 3 includes two or more gripping fingers, forming a space between them to accommodate the stator core. When the gripper 3 is closed, the gripping fingers clamp the outer wall of the stator core, achieving gripping of the stator core.

[0035] In practical use, because larger stator cores also have greater mass, placing them directly above the machining tool results in significant force between the tool and the core, potentially leading to over-cutting and affecting machining accuracy. Therefore, this application incorporates a gripping assembly with a robotic arm 2. The gripping assembly features cleats 3 that can flexibly adjust their gripping size according to the actual stator core dimensions. Under the action of the robotic arm 2, it can also grip larger, heavier stator cores. To prevent excessive force between the heavier stator core and the tool from affecting machining accuracy, the robotic arm 2 consistently applies an upward force to the stator core via the cleats 3 during machining, reducing the force between the stator core and the tool. This method not only ensures higher machining accuracy but also prevents the larger stator core from damaging the tool or reducing its lifespan.

[0036] In practical use, the high-efficiency motor stator core chamfering and end face synchronous processing device of this invention first selects a suitable limiting platform 401 according to the size specifications of the stator core to be processed. The limiting platform 401 can be replaced according to the actual size of the core to be processed. Specifically, the old limiting platform 401 is removed from the top of the fixing column 412, and then a new limiting platform 401 matching the size of the core to be processed is installed to ensure that the outer diameter of the limiting platform 401 matches the inner diameter of the stator core. Subsequently, the operator uses the gripper 3 on the robotic arm 2 to grasp the stator core to be processed. The multiple gripping fingers of the gripper 3 clamp the outer wall surface of the stator core. Then, the robotic arm 2 moves the stator core above the limiting platform 401 and slowly lowers it, placing the stator core onto the limiting platform 401. At this time, the limiting protrusion 408 is embedded in the groove of the side wall of the stator core, realizing accurate positioning and anti-rotation fixation of the stator core.

[0037] For smaller, lighter iron cores, the robotic arm 2 maintains its gripping position after placing the core on the limiting stage 401 and actively applies downward pressure. The pressure applied by the grippers 3 ensures close contact between the core and the limiting stage 401 and the fixed plate 402, further enhancing positioning stability. For larger, heavier iron cores, the robotic arm 2 releases the grippers 3 after placing the core on the limiting stage 401. The core remains stable due to its own weight and the support of the limiting stage 401 and the fixed plate 402. This design allows the device to process not only small-sized iron cores but also large-sized, heavy-weight iron cores stably, expanding the device's applicability.

[0038] After the iron core is positioned, the heights of the mounting block 405 and mounting bracket 406 are adjusted according to the thickness of the iron core to be processed and the processing requirements. By rotating the lifting screw of the lifting assembly, the mounting block 405 and mounting bracket 406 move the chamfering tool 404 and the end-face processing tool 407 up or down, adjusting the relative position between the tools and the stator iron core. This aligns the arc surface of the chamfering tool 404 with the chamfer position of the stator iron core, and the flat blade structure of the end-face processing tool 407 with the end face of the stator iron core. Simultaneously, according to the diameter of the iron core, the positions of the mounting block 405 and mounting bracket 406 along the diameter direction of the rotating disk 403 are adjusted to change the processing radius of the tools, ensuring that the tools can cover the entire processing area of ​​the iron core.

[0039] After the tool position adjustment is completed, the drive motor 413 is started via the switch panel 7. The output shaft of the drive motor 413 drives the drive pulley 409 to rotate. The drive pulley 409 drives the driven pulley 414 to rotate via the transmission belt 410. The driven pulley 414 drives the rotating disk 403 to rotate synchronously. The rotating disk 403 then drives the mounting block 405, mounting bracket 406, chamfering tool 404, and end face tool 407 to rotate together. Since the stator core remains stationary under the constraint of the limiting table 401 and the limiting protrusion 408, when the chamfering tool 404 rotates and contacts the edge of the core, the arc surface structure cuts the edge of the core to form a chamfer that meets the design requirements. At the same time, when the end face tool 407 rotates and contacts the end face of the core, the flat tool structure mills and flattens the end face of the core to remove burrs and uneven areas. With the synchronous rotation of the rotary disk 403, chamfering and end-face machining are performed simultaneously in the same clamping process. Compared with the traditional sequential machining method of chamfering first and then face machining later, the machining time is significantly shortened and the machining efficiency is improved.

[0040] During processing, the annular baffle 5 serves both safety protection and iron filings collection. The annular baffle 5 surrounds the processing area, preventing flying iron filings from scattering and injuring operators or polluting the workshop environment. Simultaneously, the iron filings collected within the annular baffle 5 facilitate subsequent unified cleaning. After processing is complete, the drive motor 413 is turned off via the switch panel 7, stopping the rotation of the chamfering cutter 404 and the end-face cutting cutter 407. Then, the robot arm 2 re-grabs the gripper 3, clamps the processed stator core, removes it from the limiting table 401, and places it in the next workstation or finished product collection area. Subsequently, the robot arm 2 picks up the next core to be processed, repeating the above processing procedure to achieve continuous batch processing of stator cores.

[0041] The technical solution of this invention, by setting up a synchronous processing component 4, utilizes a rotating disk 403 to simultaneously support the chamfering processing component and the end-face processing component, achieving synchronous processing of the stator core's chamfer and end face, significantly improving processing efficiency and saving considerable time compared to the traditional method of processing one process at a time. By setting up a limiting stage 401 and limiting protrusions 408 to fix and limit the stator core, and cooperating with the drive motor 413 driving the rotating disk 403 to rotate via belt transmission, a processing mode of workpiece stationary and tool rotating is achieved, resulting in high processing stability. This is particularly suitable for processing large-size, high-mass stator cores, effectively solving the problem of poor stability when processing large-mass cores using traditional milling machines. By setting up a lifting component to adjust the tool height, and by sliding the mounting block 405 and mounting bracket 406 relative to the diameter direction of the rotating disk 403 to adjust the tool processing radius, this device can adapt to the processing needs of stator cores of different sizes and specifications, offering flexibility and strong versatility. By setting up replaceable limit stages and adjustable tool positions, the applicability of the device is further enhanced. The corresponding limit stages can be replaced according to the actual size of the iron core being processed, or the tool positions can be adjusted to adapt to different processing requirements.

[0042] In some preferred embodiments, the limiting platform 401 adopts a modular design. The limiting platform 401 and the fixing column 412 are connected by positioning keys and bolts, which facilitates the quick replacement of limiting platforms 401 of different specifications to accommodate stator cores with different inner diameters. The number and position of the limiting protrusions 408 can be adjusted according to the specific structure of the stator core to ensure accurate matching with the groove structure of the core.

[0043] In some preferred embodiments, the lifting assembly adopts a servo motor drive combined with ball screw transmission. The servo motor drives the ball screw to rotate, and the ball screw drives the mounting block 405 or mounting bracket 406 to move precisely in the vertical direction. The servo motor is connected to the CNC system, and the operator can input the target machining height through the CNC system. The servo motor automatically adjusts the tool position to achieve automated control and improve machining accuracy and efficiency.

[0044] In some preferred embodiments, the drive motor 413 is a variable frequency speed control motor. The speed of the drive motor 413 is adjusted by the frequency converter, thereby controlling the rotation speed of the rotating disk 403. Stator cores of different materials and hardness require different cutting speeds. The variable frequency speed control function enables this device to flexibly adapt to the processing requirements of different materials.

[0045] In some preferred embodiments, the inner surface of the gripper 3 is provided with an anti-slip and wear-resistant layer. The anti-slip and wear-resistant layer can be made of rubber or polyurethane material to increase the friction between the gripper 3 and the outer wall of the stator core, prevent the core from slipping during the clamping process, and protect the core surface from being scratched by the gripper 3.

[0046] The device in this embodiment of the invention can be flexibly configured according to actual production needs. It can be set to stand-alone working mode or combined with other automated equipment to form an automated production line to achieve unattended continuous batch production.
