Description

Technical Field

[0001] This application belongs to the field of commutator processing and maintenance technology, specifically relating to an integrated machine for processing and maintaining commutators. Background Technology

[0002] A commutator, also known as a rectifier, is a device used to change the direction of current in an AC power source. It can convert the positive current of an AC power source into a negative current, or vice versa, and is used to convert DC power into AC power. It is mainly used in automotive generators, gasoline generators, and other fields.

[0003] After a period of use, the spacing between adjacent copper plates of the commutator in a large generator (i.e., mica grooves) will decrease, making it prone to short circuits. Furthermore, oxidation of the copper plates leads to poor contact with the carbon brushes, increasing the risk of sparking. In such cases, the commutator's copper plates need to be repaired. In practice, commutator maintenance mostly relies on manual labor or semi-automated equipment. Typically, roundness correction equipment and grooving / chamfering equipment are two separate pieces of equipment, resulting in a complex maintenance process and consequently low maintenance efficiency.

[0004] Of course, the aforementioned problems still exist during the machining of commutators, when performing roundness correction and chamfering. Utility Model Content

[0005] The purpose of this application is to provide an integrated machine for processing and repairing commutators, which can solve the problem that the current processing and repair procedures for commutators are quite complex.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] This application provides an integrated machine for machining and repairing commutators, including a base, a turning tool holder, and a milling tool holder. The base has a mounting station for mounting a motor rotor. Both the turning tool holder and the milling tool holder are movably mounted on the base and are arranged at intervals. The turning tool holder and the mounting station are arranged side by side along the width direction of the base. The turning tool holder includes a roundness turning tool for correcting the roundness of the commutator of the motor rotor, and the milling tool holder includes a grooving and chamfering tool for chamfering the mica grooves of the commutator.

[0008] When the motor rotor is rotatably mounted at the installation station and the integrated machine is in the first state, the roundness turning tool is directly opposite the commutator of the motor rotor, and the grooving and chamfering tool is offset from the commutator; when the motor rotor is rotatably mounted at the installation station and the integrated machine is in the second state, the roundness turning tool is offset from the commutator of the motor rotor, and the grooving and chamfering tool is directly opposite the commutator.

[0009] In this embodiment, both the turning tool holder and the milling tool holder are movably mounted on the base. When the commutator of the motor rotor needs to be repaired or machined, the motor rotor is rotatably mounted on the mounting position of the base. The integrated machine is first controlled to a first state, where the roundness turning tool of the turning tool holder faces the commutator of the motor rotor to correct its roundness, while the grooving and chamfering tool is offset from the commutator. After the roundness correction is completed, the integrated machine is controlled to a second state, where the roundness turning tool is offset from the commutator, and the grooving and chamfering tool of the milling tool holder faces the commutator to chamfer the mica grooves of the commutator. Using this integrated machine to machine or repair the commutator of the motor rotor allows for sequential roundness correction and grooving / chamfering on the same machine without moving between different machines. This simplifies the machining and repair processes of the commutator, thereby improving the efficiency of commutator machining and repair. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The integrated machine for processing and repairing commutators provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0025] like Figures 1 to 5As shown in the illustration, this application discloses an integrated machine for machining and repairing a commutator 910, comprising a base 100, a turning tool holder 200, and a milling tool holder 300. Optionally, the turning tool holder 200 can be a horizontal tool holder, a vertical tool turret, or a vertical tool post, etc., and this application does not impose specific limitations on this. The base 100 is provided with a mounting station for mounting a motor rotor 900. When the motor rotor 900 needs to be repaired or the commutator 910 needs to be machined, the motor rotor 900 can be mounted on the mounting station of the base 100, and the motor rotor 900 can rotate relative to the base 100. Both the turning tool holder 200 and the milling tool holder 300 are movably mounted on the base 100, and are arranged at intervals to avoid mutual interference. The turning tool holder 200 and the mounting station are arranged side by side along the width direction (X-axis direction) of the base 100, that is, when the motor rotor 900 is installed on the mounting station, the turning tool holder 200 is located on one side of the motor rotor 900. The turning tool holder 200 includes a roundness turning tool 210 for roundness correction of the commutator 910 of the motor rotor 900, and the milling tool holder 300 includes a grooving and chamfering tool 310 for grooving and chamfering the mica grooves 911 of the commutator 910. When the motor rotor 900 is rotatably mounted at the installation position and the integrated machine is in the first state, the roundness turning tool 210 is directly opposite the commutator 910 of the motor rotor 900, and the grooving and chamfering tool 310 is offset from the commutator 910. When the motor rotor 900 is rotatably mounted at the installation position and the integrated machine is in the second state, the roundness turning tool 210 is offset from the commutator 910 of the motor rotor 900, and the grooving and chamfering tool 310 is directly opposite the commutator 910.

[0026] In this embodiment, both the turning tool holder 200 and the milling tool holder 300 are movably mounted on the base 100. When it is necessary to repair or process the commutator 910 of the motor rotor 900, the motor rotor 900 is rotatably mounted on the mounting position of the base 100. First, the integrated machine is controlled to be in the first state. At this time, the roundness turning tool 210 of the turning tool holder 200 is directly opposite the commutator 910 of the motor rotor 900 to correct the roundness of the commutator 910, while the grooving and chamfering tool 310 is offset from the commutator 910. After the roundness correction is completed, the integrated machine is controlled to be in the second state. At this time, the roundness turning tool 210 is offset from the commutator 910 of the motor rotor 900, and the grooving and chamfering tool 310 of the milling tool holder 300 is directly opposite the commutator 910 to groove and chamfer the mica groove 911 of the commutator 910. This integrated machine is used to process or repair the commutator 910 of the motor rotor 900. It allows for sequential roundness correction and chamfering of the commutator 910 on a single machine, eliminating the need to move it between different machines. This simplifies the processing and repair procedures for the commutator 910, thereby improving the efficiency of both processes. Therefore, this embodiment of the application solves the problem of the currently complex repair procedures for the commutator 910.

[0027] In one optional embodiment, the turning tool holder 200 further includes a first tool holder 220 and an end-face turning tool 230 for turning the end face of the commutator 910. The first tool holder 220 is movably disposed on the base 100 and can rotate relative to the base 100. The roundness turning tool 210 and the end-face turning tool 230 are both disposed on the first tool holder 220 and are arranged circumferentially spaced along the first tool holder 220. When the motor rotor 900 is rotatably mounted in the installation position and the integrated machine is in the first state, both the roundness turning tool 210 and the end-face turning tool 230 can face the commutator 910. Specifically, when the motor rotor 900 is rotatably mounted on the mounting position of the base 100 and the integrated machine is in the first state, the roundness turning tool 210 first corrects the roundness of the commutator 910 of the motor rotor 900. At this time, the end face turning tool 230 is offset from the commutator 910. After the roundness of the commutator 910 is qualified, the first tool holder 220 is rotated to offset the roundness turning tool 210 from the commutator 910, and the end face turning tool 230 faces the commutator 910. At this time, the end face turning tool 230 turns the end face of the commutator 910 to clean the end face of the commutator 910. Of course, the end face turning tool 230 may not be provided.

[0028] In a further optional embodiment, the turning tool holder 200 also includes a brush 240 for cleaning the mica groove 911 of the commutator 910. The brush 240 is disposed on the first tool holder 220. The brush 240, the roundness turning tool 210 and the end face turning tool 230 are arranged sequentially at intervals along the circumference of the first tool holder 220. When the motor rotor 900 is rotatably mounted at the installation position and the integrated machine is in the second state, the brush 240 can face the commutator 910. Specifically, when the motor rotor 900 is rotatably mounted on the mounting position of the base 100 and the integrated machine is in the second state, after the grooving and chamfering cutter 310 completes the grooving and chamfering of each mica groove 911 of the commutator 910, the first tool holder 220 is moved and / or rotated so that the brush 240 is facing the mica groove 911 of the commutator 910, thereby cleaning the residual debris in the mica groove 911 and preventing metal debris generated during the grooving and chamfering process from adhering to the mica groove 911. Of course, the brush 240 can also be replaced with a blowing component.

[0029] In another optional embodiment, the turning tool holder 200 further includes a support frame 250 and a first drive assembly. The support frame 250 is movably disposed on the base 100, and the first tool holder 220 is rotatably disposed on the support frame 250. The support frame 250 supports the first tool holder 220 and the roundness turning tool 210 disposed on the first tool holder 220, so that the position of the roundness turning tool 210 is substantially equal to the position of the motor rotor 900, so as to facilitate roundness correction of the motor rotor 900. The first drive assembly is disposed on the base 100 and connected to the support frame 250. The first drive assembly can drive the support frame 250 to move relative to the base 100, so that the first tool holder 220 moves closer to or further away from the mounting position. Specifically, when the motor rotor 900 is rotatably mounted on the mounting position of the base 100, and the first tool holder 220 is close to the mounting position, the first tool holder 220 is close to the motor rotor 900 so that the roundness turning tool 210 can correct the roundness of the commutator 910 of the motor rotor 900. When the first tool holder 220 is away from the mounting position, it allows the grooving and chamfering tool 310 of the milling tool holder 300 to move to face the commutator 910 of the motor rotor 900, or facilitates the placement of the motor rotor 900 on or away from the mounting position. In addition, the support frame 250 is driven to move relative to the base 100 by the first drive assembly, so that the milling tool holder 300 can be moved flexibly relative to the base 100 by electric control, which helps to improve the automation of the equipment and reduce manual operation.

[0030] Optionally, the first drive assembly includes a first drive member and a second drive member connected together. The first drive member is disposed on the base 100, and the second drive member is connected to the support frame 250. The first drive member can drive the second drive member, the support frame 250, and other structures to move together along the length direction (Z-axis direction) of the base 100. The second drive member can drive the support frame 250, the first tool holder 220, and other structures to move together along the width direction of the base 100, so that the turning tool holder 200 can move relative to the base 100 in multiple directions, thereby improving the movement flexibility of the turning tool holder 200 to better adapt to motor rotors 900 of different sizes. Optionally, at least one of the first drive member and the second drive member may include a lead screw and nut mechanism and a servo motor; of course, other types of drive members may also be used, and this embodiment does not impose specific limitations on this.

[0031] In another optional embodiment, the milling tool holder 300 further includes a second tool holder 320, a milling cutter shank 330, and a first drive source. Optionally, the milling cutter shank 330 can be a vertical structure, and the second tool holder 320 is movably mounted on the base 100. The second tool holder 320 can be located below the mounting position of the base 100, or above the mounting position of the base 100, to avoid interference with the turning tool holder 200. The first drive source is disposed on the second tool holder 320, and the output shaft of the first drive source is connected to the first end of the milling cutter shank 330. The second end of the milling cutter shank 330 is connected to the grooving and chamfering tool 310. The first drive source can drive the milling cutter shank 330 and the grooving and chamfering tool 310 to move up and down relative to the base 100 together to accommodate the commutator 910 with a large deflection of the mica groove 911, thereby expanding the applicability of the integrated machine. Of course, the milling cutter holder 330 and the first drive source can be omitted, and the grooving and chamfering tool 310 can be directly installed on the second tool holder 320.

[0032] In a further optional embodiment, the milling tool holder 300 further includes a second drive assembly disposed on the base 100. The second drive assembly is connected to the second tool holder 320 and can drive the second tool holder 320 to move relative to the base 100, so that the second tool holder 320 moves closer to or away from the mounting position. Specifically, when the motor rotor 900 is rotatably mounted on the mounting position of the base 100 and the second tool holder 320 is close to the mounting position, the second tool holder 320 is close to the motor rotor 900 so that the grooving and chamfering tool 310 can groove and chamfer the mica groove 911 of the commutator 910 of the motor rotor 900; when the second tool holder 320 is away from the mounting position, it allows the roundness turning tool 210 of the turning tool holder 200 to move to face the commutator 910 of the motor rotor 900, or facilitates the placement of the motor rotor 900 on or away from the mounting position. In addition, the second tool holder 320 is driven to move relative to the base 100 by the second drive component, so that the turning tool holder 200 can be moved flexibly relative to the base 100 by electric means. This helps to improve the automation of the equipment and reduce manual operation.

[0033] Optionally, the second drive assembly includes a third drive member and a fourth drive member connected in sequence. The third drive member is disposed on the base 100, and the fourth drive member is connected to the second tool holder 320. The third drive member can drive the fourth drive member, the second tool holder 320, and other structures to move together along the length direction of the base 100. The fourth drive member can drive the second tool holder 220, the first drive source, and other structures to move together along the width direction of the base 100, so that the milling tool holder 300 can move relative to the base 100 in multiple directions, thereby improving the movement flexibility of the milling tool holder 300 to better adapt to motor rotors 900 of different sizes. Optionally, at least one of the third and fourth drive members may include a lead screw and nut mechanism and a servo motor. Of course, other types of drive members may also be used; this embodiment does not impose specific limitations on this.

[0034] In an optional embodiment, the integrated machine further includes a first detection element 400. Optionally, the first detection element 400 can be a laser detection element. The first detection element 400 is movably disposed on the base 100. Optionally, the first detection element 400 can move along the length direction of the base 100. The first detection element 400 is located above the installation station. When the motor rotor 900 is rotatably installed at the installation station and the integrated machine is in the first state, the first detection element 400 faces the commutator 910 to detect the roundness value of the commutator 910. The roundness turning tool 210 is used to round the commutator 910 according to the roundness value detected by the first detection element 400. Degree correction; when the motor rotor 900 is rotatably installed at the installation position and the integrated machine is in the second state, the first detection element 400 faces the commutator 910 to detect whether the size of the mica groove 911 of the commutator 910 is less than a preset value. Here, the size specifically includes parameters such as the groove width, groove depth, and chamfer angle of the mica groove 911. The preset value can be a specific value or a range of values. This application embodiment does not impose specific limitations on this. In addition, it should be noted that when the size here includes multiple parameters such as the groove width, groove depth, and chamfer angle of the mica groove 911, the preset value corresponds one-to-one with the above parameters, and each preset value can be different.

[0035] Specifically, when the grooving and chamfering tool 310 grooves and chamfers the mica grooves 911 of the commutator 910, the first detection element 400 detects the size of each mica groove 911 after it is grooved. If the size of the mica groove 911 is less than a preset value, the equipment issues an alarm to prompt the operator to handle it manually. If the size of the mica groove 911 is greater than or equal to the preset value, it indicates that the requirements are met, and the grooving and chamfering tool 310 will continue grooving until the grooving and chamfering process of the entire commutator 910 is completed. This solution, by setting the first detection element 400 to detect the commutator 910, helps to improve the correction accuracy of the roundness turning tool 210, thereby improving the working efficiency of the roundness turning tool 210; furthermore, it can improve the dimensional accuracy of the mica grooves 911 of the commutator 910, thereby extending the service life of the motor rotor.

[0036] In another optional embodiment, the all-in-one device further includes a second detection element 500. Optionally, the second detection element 500 can be a laser detection element. The second detection element 500 is movably disposed on the base 100. Optionally, the second detection element 500 can move along the length direction of the base 100 or along the width direction of the base 100. No specific limitation is made here. The second detection component 500 and the installation station are arranged side by side along the length of the base 100. When the motor rotor 900 is rotatably installed on the installation station of the base 100 and the integrated machine is in the second state, the second detection component 500 faces the end face of the commutator 910 to detect the position of the mica groove 911 of the commutator 910 and accurately index and position the mica groove 911. The grooving and chamfering tool 310 automatically aligns with the mica groove 911 of the commutator 910 according to the detection value of the second detection component 500 to groove and chamfer the mica groove 911, avoid the position of the grooving and chamfering tool 310 from being offset from the original mica groove 911, eliminate the cumulative indexing error, and thus improve the grooving accuracy of the grooving and chamfering tool 310.

[0037] In a further optional embodiment, the turning tool holder 200 further includes a first tool holder 220 and an end face turning tool 230 for turning the end face of the commutator 910. The first tool holder 220 is movably disposed on the base 100 and can rotate relative to the base 100. The roundness turning tool 210 and the end face turning tool 230 are both disposed on the first tool holder 220 and are arranged at intervals along the circumference of the first tool holder 220. When the motor rotor 900 is rotatably mounted on the mounting position of the base 100 and the integrated machine is in the first state, both the roundness turning tool 210 and the end face turning tool 230 can face the commutator 910. After the roundness correction of the commutator 910 is qualified, the first tool post 220 is rotated so that the roundness turning tool 210 is offset from the commutator 910, and the end face turning tool 230 is facing the commutator 910. At this time, the end face turning tool 230 turns the end face of the commutator 910 to clean the end face of the commutator 910, thereby avoiding the impurities on the end face of the commutator 910 from interfering with the second detection element 500, and thus improving the detection accuracy of the second detection element 500.

[0038] In another optional embodiment, the integrated device further includes a dynamic balancing detection component 600, which is movably mounted on the base 100 and located below the installation position. The dynamic balancing detection component 600 is used to detect the dynamic balance of the motor rotor 900. When the integrated device is in the third state, the motor rotor 900 is supported on the dynamic balancing detection component 600. Specifically, after the commutator 910 of the motor rotor 900 completes roundness correction and chamfering, the dynamic balancing detection component 600 is raised to support the motor rotor 900, thereby detecting the dynamic balance of the motor rotor 900 to ensure it meets usage requirements and prevents vibration, noise, and accelerated bearing wear during operation.

[0039] Optionally, during the dynamic balancing test of the motor rotor 900, the rotating shaft of the motor rotor 900 is connected to the main shaft on the base 100 via a universal joint to drive the motor rotor 900 to select, thereby performing dynamic balance correction.

[0040] The dynamic balancing test component 600 includes a first support and a second support that are arranged opposite to each other and spaced apart. Both the first support and the second support can move relative to the base 100 along its length to accommodate motor rotors 900 of different sizes.

[0041] In another optional embodiment, the base 100 includes a seat body 110 and a tail seat 120 that are slidably connected. The seat body 110 is provided with a mounting protrusion 111. The tail seat 120 and the mounting protrusion 111 are spaced apart along the length direction of the base 100 to form an installation station between the tail seat 120 and the mounting protrusion 111. The tail seat 120 can slide relative to the seat body 110 to move closer to or further away from the mounting protrusion 111, thereby adapting to motor rotors 900 of different sizes and thus improving the applicability of the integrated machine. A chuck 130 is rotatably mounted on the side of the mounting protrusion 111 facing the tailstock 120. Optionally, the chuck 130 can be driven to rotate by a motor or other drive component. The chuck 130 is used to connect the first end of the motor rotor 900. A tailstock pin 140 is provided on the side of the tailstock 120 facing the mounting protrusion 111. The tailstock pin 140 abuts against the second end of the motor rotor 900. At this time, the motor rotor 900 is clamped in the mounting position. The commutator 910 is located at the second end of the motor rotor 900. The turning tool holder 200 is movably mounted on the base 110, and the milling tool holder 300 is movably mounted on the tailstock 120. During the process of roundness correction and grooving and chamfering of the motor rotor 900, the chuck 130 can drive the motor rotor 900 to rotate to meet the process requirements of machining or repairing the commutator 910.

[0042] It should be noted that all the structures mentioned above that can move relative to the base 100 can be driven by drive components. Specifically, each drive component can be controlled by a control component to drive the structure to move relative to the base 100, thereby improving the automation performance of the integrated machine and reducing manual operation procedures.

[0043] The working principle of the all-in-one device provided in this application embodiment is as follows:

[0044] Workers hoist the motor rotor 900, which is to be processed or repaired, onto the installation position of the base 100. The motor rotor 900 is clamped by the chuck 130 and the tailstock pin 140. The chuck 130 drives the rotor to rotate. The first detection piece 400 scans the commutator 910 of the motor rotor 900, automatically detects the roundness of the commutator 910, and calculates the roundness correction amount. After the scan is completed, the turning tool holder 200 switches the roundness turning tool 210 to face the commutator 910. The tool is automatically set according to the calculated roundness correction amount, and the roundness turning tool 210 performs roundness correction. After the roundness correction is completed, the roundness of the outer circle of the commutator 910 is re-detected, and it is judged whether the detection is qualified. If the roundness detection is qualified, the next process is carried out. If it is not qualified, the roundness correction is repeated until it is qualified.

[0045] After roundness correction is completed, the turning tool holder 200 switches to the end face turning tool 230 to perform end face turning of the commutator 910 with a feed rate of 0.1 mm to clean the end face and prevent impurities on the end face from interfering with the second detection piece 500, thereby improving the detection accuracy.

[0046] After the end face turning is completed, the turning tool holder 200 is withdrawn, and the equipment switches to the grooving and chamfering tool 300. The second detection unit 500 detects and identifies the mica groove 911 of the commutator 910, so that the grooving and chamfering tool 310 automatically aligns with the mica groove 911 and performs grooving and chamfering. For each mica groove 911 grooved, the second detection unit 500 checks whether the depth, width, and chamfer angle of the mica groove 911 meet the requirements. If they do not meet the requirements, it prompts manual processing. If they meet the requirements, it continues grooving until it is completed.

[0047] After the grooving and chamfering are completed, the turning tool holder 200 switches to brush 240 to remove residual debris from the mica groove 911. Next, the dynamic balancing test piece 600 is raised, and the motor rotor 900 is lowered onto it for dynamic balancing testing. During this process, the motor rotor 900's shaft is connected to the spindle on the base 100 via a universal joint to drive the motor rotor 900 to rotate, and then dynamic balancing correction is performed. Once the dynamic balancing correction is completed, the maintenance or machining process of the commutator 910 is finished.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
