Description

Technical Field

[0001] This application relates to the field of mechanical repair technology, and in particular to a wire disconnection device based on rapid motor repair. Background Technology

[0002] As a core power device in industrial transmission, energy and power, and transportation equipment, the importance of electric motors is self-evident. The stator, as the stationary component of the motor, forms the foundation of the motor's magnetic and electrical circuits. The stator coils, as the core of the stator's circuitry, are wound and embedded in the stator slots through a series of rigorous processes. To improve insulation strength and mechanical integrity, the stator, after winding, undergoes impregnation and drying to bond the coils, insulation structure, and stator core into a strong whole. This sophisticated design and process enable motors to operate more stably and efficiently, playing a crucial role in various fields. The continuous development of motor technology has also driven the continuous progress of these numerous industries. In industrial production, motors provide power to various mechanical equipment, improving production efficiency and promoting industrialization; in the energy and power sector, the stable operation of motors ensures the normal transmission and conversion of electricity; and in transportation equipment, motors provide power support for various vehicles, improving people's travel conditions.

[0003] Currently, there are several common methods for removing motor stator coils. Traditional methods often rely on manual prying and pulling of the coils, requiring workers to use simple tools to separate the coils from the stator slots bit by bit. In addition, there are existing vertical coil removal devices that place the motor stator on a turntable fixture and then use a mechanism with high-frequency resonance to gradually disperse the coils within the slots from a tightly packed state to a more even distribution, reducing friction between the coils and the slots when pulling them out.

[0004] However, existing methods for removing stator coils have many drawbacks. Traditional manual removal is cumbersome, requiring workers to concentrate for extended periods, which is not only laborious but also inefficient. Furthermore, high-frequency resonance-based removal equipment, with repeated use, can damage internal components due to the high-frequency resonance, leading to a shortened lifespan of the device.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a wire disconnection device based on rapid motor repair, so as to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] To address the shortcomings of the aforementioned technologies, this application provides a wire disconnection device based on rapid motor repair.

[0007] This application provides a wire disconnection device based on rapid motor repair, which adopts the following technical solution: A wire removal device for rapid motor repair includes a fixing mechanism for supporting the stator and a wire removal mechanism for removing the coil inside the stator. The fixing mechanism is located on one side of the wire removal mechanism. The fixing mechanism is provided with heating jaws for fixing and heating the stator. An arc-shaped cast aluminum heating block is provided on the inner side of the heating jaws.

[0008] By adopting the above technical solution, a fixing mechanism is set up to support the stator whose coil is cut off on one side, providing stable support for the wire removal operation; the wire removal mechanism can pull the coil directly out from the other side of the stator to remove the motor stator coil; the heating claws in the fixing mechanism can fix the stator, and the stator is heated by the arc-shaped cast aluminum heating block on the inner side, causing the insulation enamel to decompose, reducing the resistance between the coil in the slot and the iron core slot wall, making it easier to pull out the coil.

[0009] In one optional embodiment, the fixing mechanism further includes a position adjustment component, a bottom abutment component, and a side abutment component. The bottom abutment component and the side abutment component are respectively disposed on the position adjustment component. The bottom abutment component is connected to the side abutment component via a transmission component. The heating gripper is disposed inside both the bottom abutment component and the side abutment component.

[0010] By adopting the above technical solution, the position adjustment component can adjust the position of the bottom abutment component and the side abutment component, making it easy to adapt to stators of different specifications; the bottom abutment component and the side abutment component work together to fix the stator in multiple directions, and the heating claws inside them can heat up the stator, causing the insulation enamel to decompose, reducing the resistance between the coil in the slot and the iron core slot wall, and facilitating wire disconnection; at the same time, the transmission component realizes the linkage transmission of the bottom abutment component and the side abutment component, improving the convenience and stability of operation.

[0011] In one optional embodiment, the position adjustment assembly includes a fixed base, on which a first telescopic drive member is fixedly mounted. A guide post is provided on one side of the fixed base, and a connecting plate is provided on the top of the first telescopic drive member. The connecting plate is sleeved on the guide post, and a support frame is provided on the other side of the connecting plate. A guide wheel is rotatably mounted on one side of the support frame, and the guide wheel abuts against the fixed base. A limit plate is vertically mounted on the support frame, and a first working groove is formed on the limit plate. The bottom abutment component and the side abutment component are provided on the limit plate, and the side abutment components are respectively located on both sides of the bottom abutment component.

[0012] By adopting the above technical solution, the first telescopic drive component on the fixed seat can drive the connecting plate to move along the guide column, thereby driving the support frame to move and realize position adjustment; the guide wheel abutting against the fixed seat can ensure the stability of the support frame movement; the first working groove is opened on the limit plate to facilitate subsequent wire disassembly operation; the limit plate is provided with a bottom abutting component and a side abutting component, and the bottom abutting component is provided on both sides, which can better abut and fix the stator in multiple directions.

[0013] In one optional embodiment, the bottom abutment assembly includes a second telescopic drive member, which is vertically fixedly disposed on the bottom surface of the support frame. A first support frame is hinged to the top of the telescopic end of the second telescopic drive member. A support column is disposed at the top of the first support frame. The heating gripper is fixedly disposed at the top of the support column. A guide block is disposed on the side of the first support frame facing the limiting plate. A first guide groove is vertically disposed on the limiting plate. The guide block is slidably disposed in the first guide groove.

[0014] By adopting the above technical solution, the second telescopic drive can drive the first support frame, which is hinged to the top of its telescopic end, to move. The first support frame is guided by the guide block sliding in the first guide groove of the limiting plate to ensure the stability of movement. At the same time, the first support frame drives the heating claw on the top support column to move, so as to accurately fix and heat the stator, decompose the stator insulation enamel, reduce the resistance between the coil in the slot and the iron core slot wall, and facilitate subsequent wire removal.

[0015] In one optional embodiment, the side abutment assembly includes a first elastic telescopic member, which is vertically disposed on the bottom surface of the support frame. The bottom end of the first elastic telescopic member is hinged to the bottom of the support frame. A second support frame is hinged to the top end of the first elastic telescopic member. A guide block is disposed on the side of the second support frame facing the limiting plate. A second guide groove is provided on the limiting plate. The guide block is slidably disposed in the second guide groove. The heating gripper is hinged to the second support frame facing the direction of the stator placement position.

[0016] By adopting the above technical solution, the first elastic telescopic component can drive the second support frame to slide along the second guide groove, allowing the heating claws on the second support frame to flexibly adjust their position, better supporting and fixing the stator. Combined with the heating function of the heating claws, heating further reduces the resistance between the coil inside the groove and the iron core groove wall, making it easier for the subsequent wire-pulling assembly of the wire-removing mechanism to remove the coil from the stator, thus improving wire-removing efficiency. Simultaneously, the side abutment component, together with the bottom abutment component, can perform fixing and heating operations on the stator from multiple directions, enhancing the fixing effect and heating uniformity of the stator, and improving the stability and reliability of the wire-removing operation.

[0017] In one optional embodiment, the transmission assembly includes a third support frame, a third guide groove is provided on the limiting plate, the third support frame is slidably disposed in the third guide groove, the third support frame is connected to the first support frame through a first connecting arm, the two ends of the first connecting arm are respectively hinged to the third support frame and the first support frame, and the third support frame is connected to the second support frame through a second connecting arm, the two ends of the second connecting arm are respectively hinged to the third support frame and the second support frame.

[0018] By adopting the above technical solution, the bottom abutment component and the side abutment component are linked by the transmission component. When the second telescopic drive component moves the first support frame, the first support frame drives the third support frame to slide in the third guide groove through the first connecting arm. The third support frame then drives the second support frame to move through the second connecting arm, thereby enabling the bottom and side heating claws to work together to provide a stable circumferential fixation for the stator. Combined with the arc-shaped cast aluminum heating block on the inner side of the heating claw, the stator is heated to decompose the insulation coating inside the stator, reducing the resistance between the coil in the groove and the iron core groove wall, making it easier for the subsequent wire pulling component of the wire removal mechanism to smoothly remove the coil from the stator.

[0019] In one optional embodiment, the wire removal mechanism includes a fixing plate, which is arranged parallel to the limiting plate. A second working groove is provided on the fixing plate corresponding to the first working groove. A fixing frame is provided on the other side of the fixing plate. The fixing plate and the fixing frame are connected by two symmetrically arranged guide rails. A third telescopic drive member is horizontally arranged on the top of the fixing frame. The driving end of the third telescopic drive member is provided with a pull wire assembly for pulling out the circumferentially fixed insulated end coil.

[0020] By adopting the above technical solution, the fixed plate and the limiting plate are set in parallel, and the second working groove is set on the fixed plate corresponding to the first working groove, which ensures the correspondence and coordination of the working position; the fixed plate and the fixed frame are connected by the guide rail, making the movement of the components more stable; the horizontally set third telescopic drive component drives the wire pulling assembly, which can effectively pull the circumferentially fixed insulated end coil out from the stator, realize the removal of the coil inside the stator, and improve the working effect and efficiency of the wire removal device.

[0021] In one optional embodiment, the pull cable assembly includes a threaded rod rotatably connected to the telescopic end of the third telescopic drive member. One end of the threaded rod is provided with a limiting piece, and the telescopic end of the third telescopic drive member has a limiting groove. The limiting piece is rotatably disposed within the limiting groove. A limiting sleeve is fitted onto the threaded rod and threadedly connected to it. Both ends of the limiting sleeve are fixedly connected to the guide rails on both sides via limiting arms. The other end of the threaded rod is fitted with a limiting disc, which is coaxially arranged with the threaded rod. The limiting disc is positioned on one side facing the threaded rod. An L-shaped limiting bracket is provided. A guide plate is provided on the side of the fixed plate facing the threaded rod. A fourth guide groove is opened in the guide plate. The other end of the L-shaped limiting bracket is inserted into the fourth guide groove. A rotating cavity is opened in the limiting plate. A rotating disk is rotatably arranged in the rotating cavity. The rotating disk is fixedly connected to the other end of the threaded rod. Multiple L-shaped arms are evenly arranged on the rotating disk. The L-shaped arms are rotatably connected to the rotating disk. A hanging block is hinged to the other end of the L-shaped arm. A slot is opened on the circumferential side wall of the limiting plate corresponding to the hanging block. The hanging block is inserted into the slot.

[0022] By adopting the above technical solution, the pull wire assembly can achieve rotational connection and restriction with the third telescopic drive component. The limiting sleeve cooperates with the guide rail to restrict the axial movement of the threaded rod. The L-shaped limiting frame cooperates with the guide groove of the guide plate to make the limiting plate move smoothly with the threaded rod. The rotating plate drives the L-shaped arm and the hanging block to rotate. The hanging block can be inserted into the slot of the limiting plate, which makes it easy to pull out the circumferentially fixed insulated end coil, improving the convenience and efficiency of wire removal.

[0023] In one optional embodiment, the wire hanging block has a wire hanging groove on the side facing the threaded rod, and the wire hanging block has an inclined surface on the side away from the rotating disk.

[0024] By adopting the above technical solution, the hanging block with the hanging groove can easily hang the insulated end coil inside the motor stator and pull it out easily; the inclined surface of the hanging block on the side away from the rotating disk helps to better engage near the coil when pulling the wire, which facilitates the hanging operation and thus more efficiently removes the insulated end coil that is fixed circumferentially inside the stator.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The heating jaws can fix and heat the stator, causing the insulation enamel to decompose, reducing the resistance between the coil in the slot and the iron core slot wall, making it easier to pull out the coil, and solving the problems of cumbersome, laborious and inefficient traditional manual wire removal operation; 2. It avoids the impact on internal components caused by high-frequency resonance during wire removal, thus helping to extend the service life of the wire removal device; 3. The setup, with a fixed mechanism supporting the stator and a wire removal mechanism extracting the coils from the stator, has a clear division of labor and can more efficiently remove the motor stator coils.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0032] The present invention provides the following embodiments: This application discloses a wire disconnection device based on rapid motor repair, referring to... Figure 1 The system includes a fixing mechanism 200 for supporting the stator 100 and a dismantling mechanism 300 for removing the coils from the stator 100. The fixing mechanism 200 is located on one side of the dismantling mechanism 300. The fixing mechanism 200 is equipped with heating grippers 400 for fixing the stator 100 with one side of the coil cut off and for heating the stator 100. The inner side of the heating grippers 400 is provided with an arc-shaped cast aluminum heating block 500. This allows the stator 100 to be fixed by the heating grippers 400 and the arc-shaped cast aluminum heating block 500 to heat it, causing the insulation varnish inside the stator 100 to decompose. The arc-shaped cast aluminum heating block 500 in this solution heats the stator 100 to a temperature of 100-140℃, reducing the resistance between the coils in the slot and the iron core slot wall, facilitating the removal of the coils by the dismantling mechanism 300, and not damaging the insulation varnish film of the stator 100, so that the stator 100 can be recycled to a certain extent in the future.

[0033] Specifically, the fixing mechanism 200 also includes a position adjustment component 201, a bottom abutment component 202, and a side abutment component 203. Through the cooperation of these components, the fixing mechanism 200 can more accurately fix the stator 100 and adapt to the fixing requirements of motor stators 100 of different specifications.

[0034] The position adjustment assembly 201 includes a fixed base 2011, which is generally made of metal, such as steel or aluminum alloy, and has sufficient strength and stability. A first telescopic drive component 2012 is fixedly mounted on the fixed base 2011. The first telescopic drive component 2012 can be a hydraulic telescopic rod or an electric push rod. A guide post 2013 is provided on one side of the fixed base 2011. The guide post 2013 is usually a smooth-surfaced metal cylinder to ensure smooth sliding of subsequent components. A connecting plate 2014 is provided on the top of the first telescopic drive component 2012. The connecting plate 2014 is fitted onto the guide post 2013, so that the connecting plate 2014 can move smoothly along the guide post 2013 when the first telescopic drive component 2012 extends or retracts. A support frame 2015 is provided on the other side of the connecting plate 2014, which supports subsequent components. A guide wheel 2016 is rotatably mounted on one side of the support frame 2015. The guide wheel 2016 can be a rubber wheel or a plastic wheel. The guide wheel 2016 abuts against the fixed seat 2011. The guide wheel 2016 reduces the friction when the support frame 2015 moves, making the movement smoother. A limit plate 2017 is vertically mounted on the support frame 2015. The limit plate 2017 has a first working groove 2018. The limit plate 2017 is provided with a bottom abutment component 202 and a side abutment component 203. The bottom abutment component 202 has side abutment components 203 on both sides. The position adjustment component 201 can adjust the position of the support frame 2015 and the components above it by combining the various components to adapt to the installation and disassembly requirements of different stators 100. For example, the extension or retraction of the first telescopic drive member 2012 can drive the connecting plate 2014 and the support frame 2015 to move up and down, thereby adjusting the relative positions of the bottom abutment component 202 and the side abutment component 203 with the stator 100.

[0035] The bottom abutment component 202 includes a second telescopic drive component 2021, which can also be a hydraulic telescopic rod or an electric push rod, and is vertically fixed to the bottom surface of the support frame 2015. A first support frame 2022 is hinged to the top of the telescopic end of the second telescopic drive component 2021. The first support frame 2022 is typically welded from metal sheets and has a certain degree of rigidity. A support column 2023 is provided at the top of the first support frame 2022. The support column 2023 is generally a cylindrical metal rod, and a heating gripper 400 is fixedly provided at the top of the support column 2023. The heating gripper 400 can be made of a high-temperature resistant alloy material. A guide block is provided on the side of the first support frame 2022 facing the limiting plate 2017. The guide block can be a square metal block. A first guide groove 2024 is vertically provided on the limiting plate 2017. The guide block is slidably disposed in the first guide groove 2024. In this way, when the second telescopic drive member 2021 extends and retracts, the first support frame 2022 can move vertically and smoothly with the cooperation of the guide block and the first guide groove 2024, so that the heating gripper 400 accurately abuts against the bottom of the stator 100.

[0036] The side abutment assembly 203 includes a first elastic telescopic member 2031, which can be a spring telescopic rod. It is vertically mounted on the bottom surface of the support frame 2015. The bottom end of the first elastic telescopic member 2031 is hinged to the bottom of the support frame 2015. A second support frame 2032 is hinged to the top end of the first elastic telescopic member 2031. The structure and material of the second support frame 2032 are similar to those of the first support frame 2022. A guide block is provided on the side of the second support frame 2032 facing the limiting plate 2017. A second guide groove 2033 is provided on the limiting plate 2017, and the guide block slides within the second guide groove 2033. A heating gripper 400 is hinged to the second support frame 2032 facing the placement position of the stator 100. The elastic telescopic member of the side abutment assembly 203 allows the heating gripper 400 to flexibly abut against the side of the stator 100 and can adapt to certain changes in the size of the stator 100. Bottom abutment component 202 and side abutment component 203 are respectively disposed on position adjustment component 201. Bottom abutment component 202 and side abutment component 203 are respectively connected to each other via transmission component 204. Transmission component 204 includes third support frame 2041. A third guide groove 2042 is provided on limit plate 2017. Third support frame 2041 is slidably disposed in third guide groove 2042. Third support frame 2041 is connected to first support frame 2022 via first connecting arm 2043. Both ends of first connecting arm 2043 are hinged to third support frame 2041 and first support frame 2022 respectively. Third support frame 2041 is connected to second support frame 2032 via second connecting arm 2044. Both ends of second connecting arm 2044 are hinged to third support frame 2041 and second support frame 2032 respectively. When the bottom abutment component 202 is activated, the transmission component 204 drives the side abutment component 203 to move synchronously, achieving simultaneous fixation and heating of the bottom and side of the stator 100. The second telescopic drive component 2021 extends upward, driving the first support frame 2022 to rise. The first support frame 2022 drives the third support frame 2041 to slide in the third guide groove 2042 via the first connecting arm 2043. The third support frame 2041 then drives the second support frame 2032 to move via the second connecting arm 2044, causing the heating claw 400 of the side abutment component 203 to approach the side of the stator 100.

[0037] Specifically, the wire removal mechanism 300 includes a fixing plate 301, which is arranged parallel to the limiting plate 2017. A second working groove 302 is provided on the fixing plate 301 corresponding to the first working groove 2018. A fixing frame 303 is provided on the other side of the fixing plate 301. The fixing plate 301 and the fixing frame 303 are connected by two symmetrically arranged guide rails 304. The guide rails 304 can be linear guide rails to ensure the accuracy of the component sliding on the guide rails 304. A third telescopic drive member 305 is horizontally arranged on the top of the fixing frame 303. The third telescopic drive member 305 can be an electric lead screw or a cylinder. The drive end of the third telescopic drive member 305 is provided with a pull wire assembly 306 for pulling out the circumferentially fixed insulated end coil.

[0038] The pull cable assembly 306 includes a threaded rod 3061, which is rotatably connected to the telescopic end of the third telescopic drive member 305. A limiting piece 3062 is provided at one end of the threaded rod 3061, and a limiting groove 3063 is formed in the telescopic end of the third telescopic drive member 305. The limiting piece 3062 is rotatably disposed within the limiting groove 3063. Thus, the threaded rod 3061 can move axially under the drive of the third telescopic drive member 305 and rotate relative to the telescopic end under the action of the limiting piece 3062 and the limiting groove 3063. A limiting sleeve 3064 is fitted onto the threaded rod 3061, threadedly connected to it. Both ends of the limiting sleeve 3064 are fixedly connected to guide rails 304 on both sides via limiting arms 3065. When the threaded rod 3061 rotates, the limiting sleeve 3064, being fixed to the guide rails 304, cannot rotate and can only move axially along the guide rails 304. A limiting disc 3066 is fitted onto the other end of the threaded rod 3061. The limiting disc 3066 is coaxially arranged with the threaded rod 3061. An L-shaped limiting bracket 3067 is provided on the side of the limiting disc 3066 facing the threaded rod 3061. A guide plate 3068 is provided on the side of the fixing plate 301 facing the threaded rod 3061. A fourth guide groove 3069 is formed in the guide plate 3068. The other end of the L-shaped limiting bracket 3067 is inserted into the fourth guide groove 3069. A rotating cavity 3 is formed in the limiting disc 3066. 070. A rotating disk 3071 is rotatably disposed within the rotating cavity 3070. The rotating disk 3071 is fixedly connected to the other end of the threaded rod 3061. Multiple L-shaped arms 3072 are evenly arranged on the rotating disk 3071. The L-shaped arms 3072 are rotatably connected to the rotating disk 3071. A wire-hanging block 3073 is hinged to the other end of the L-shaped arm 3072. A slot 3076 is provided on the circumferential side wall of the limiting disk 3066 corresponding to the wire-hanging block 3073. The wire-hanging block 3073 is inserted into the slot 3076. A wire-hanging groove 3074 is provided on the side of the wire-hanging block 3073 facing the threaded rod 3061. An inclined surface 3075 is provided on the side of the wire-hanging block 3073 away from the rotating disk 3071. When the third telescopic drive 305 drives the threaded rod 3061 to move, the threaded rod 3061 rotates, causing the limit sleeve 3064 to move, which in turn drives the entire wire pulling assembly 306 to move. The wire hanging block 3073 hangs the coil through the wire hanging groove 3074, and under the action of the inclined surface 3075, it is easier to insert it under the coil. As the wire pulling assembly 306 moves, the coil is pulled out.

[0039] The implementation principle of this embodiment is as follows: The wire removal device, through the cooperation of the fixing mechanism 200 and the wire removal mechanism 300, can efficiently remove the coil inside the motor stator 100. The position adjustment component 201 in the fixing mechanism 200 can adjust the overall position, while the bottom abutment component 202 and the side abutment component 203 can simultaneously fix and heat the bottom and side of the stator 100, causing the insulation varnish inside the stator 100 to decompose and reducing the resistance between the coil and the iron core slot wall. Driven by the third telescopic drive component 305, the wire pulling component 306 of the wire removal mechanism 300, through the cooperation of the threaded rod 3061 and the limiting sleeve 3064, drives the hanging block 3073 to hook the coil and pull it out. Compared with the traditional manual wire removal method, the operation is simpler and less labor-intensive, greatly improving work efficiency; at the same time, it avoids the impact of high-frequency resonance on equipment parts, extends the service life of the equipment, meets the needs of rapid motor repair, and has significant improvements and contributions to the motor repair industry.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation.
