Description

Technical Field

[0002] The commutator is a component used for current commutation in DC motors and AC series-excited motors. In order to keep the motor rotating, it is commonly known as a commutator. During the rough machining of the commutator, some machining marks, burrs or defects may be left. These defects may affect the performance and life of the commutator. Therefore, it is necessary to fine-turn the surface of the commutator. Through turning, these defects can be removed to make the commutator surface smoother and flatter.

[0003] The patent with announcement number CN217798965U discloses a commutator surface finishing device, including a rotor support seat, a support wheel, a pressure wheel, a limit plate and a push rod; two groups of the support wheels are arranged on the rotor support seat in parallel along the first axis, and the pressure wheel is arranged on the rotor support seat and located above the support wheel; the limit plate and the push rod are arranged on the rotor support seat along the second axis and are respectively located on both sides of the support wheel; the first axis is perpendicular to the second axis. Compared with the traditional rotor finishing machine, the commutator surface finishing device provided by the patent improves the positioning accuracy of the rotor, enhances the stability of the rotor during the machining operation, and is conducive to improving the machining quality of the rotor commutator head.

[0004] However, the above technical solution still has the following deficiencies in practical application: Since the commutator is composed of many commutator segments, these commutator segments are usually evenly distributed along the circumference of the commutator, and there are gaps between the commutator segments. This uniform distribution can ensure that the flow of current in the winding is smoothly reversed. When the above technical solution is in use, a certain amount of metal debris will be generated due to the friction and cutting action between the tool and the commutator surface, and these debris may remain in the commutator segment gaps. The residue of debris will affect the flatness of the commutator surface, resulting in a decrease in motor performance, and may even cause a short circuit between the commutator segments, causing motor failure.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention discloses a turning device for finishing the surface of a commutator, wherein the inner hole of the commutator to be turned is sleeved on the outer side of a positioning plate, and a third electric push rod is used to drive a support block to slide, so that the support block moves toward the outer side of the positioning plate, and a protrusion is formed on the surface of the positioning plate to support the bottom of the commutator. At the same time, a second electric push rod is used to drive a positioning plate on one side to slide, and with the cooperation of connecting rods one and two, a plurality of positioning plates can be simultaneously slid radially until the positioning plate fits with the inner hole wall of the commutator, and the commutator can be fixed, thereby achieving a positioning effect on commutators with different inner hole diameters, thereby ensuring the stability of the commutator during the turning process and preventing it from shifting.

[0018] 2. The turning device for finishing the surface of a commutator described in the present invention utilizes a stacked correction type cleaning mechanism. When a commutator is turned, the bristles of the brush roller can be driven to extend into the gaps of the commutator segments of the commutator, and the brush roller can be driven to rotate to clean the debris in the gaps of the commutator segments to remove the debris. In addition, the commutator can be driven to rotate to allow the bristles to extend into the gaps of the commutator segments at different positions, thereby achieving comprehensive cleaning of the debris in the gaps of the commutator segments, thereby avoiding the flatness of the commutator surface being affected by the debris remaining in the gaps of the commutator segments, thereby causing the motor performance to decline. There may even be a short circuit between the commutator segments, causing motor failure. In addition, when multiple commutators need to be turned in sequence, each time a commutator is turned, the commutator is stacked on the placement disk. When the placement disk accumulates a certain number of commutators, the plug-in rod is driven to move horizontally and approach the stacked commutators. The plug-in rod will be squeezed with the commutator segments and inserted into the gap between the commutator segments. At this time, the placement disk is driven to rotate, and the plug-in rod will resist the commutator segments and block the rotation of the commutator until all the commutator segments overlap and all the commutators are at the same angle. At this time, the placement disk is driven to rotate, and the plug-in rod will resist the commutator segments and block the rotation of the commutator until all the commutator segments overlap and all the commutators are at the same angle. The positioning plate is used to fix all the commutators, and then the brush roller is driven to extend into the gap of the commutator segments, so that the bristles can extend into the gap of the commutator segments of all the commutators, and then the above cleaning work is repeated, thereby realizing the unified removal of debris in the gaps of all the commutator segments, and the cleaning work is only performed once, thereby reducing the working frequency of the brush roller and improving the turning efficiency. In addition, since multiple commutators are neatly stacked on the placement disk, the commutators that have been turned can also be stored, which is conducive to the subsequent unified collection and transportation of the commutators. When the commutator on the placement disk needs to be removed When the commutator is collected, the positioning plate can be driven to tilt and the commutator can slide off the positioning plate and then be collected. Moreover, when the number of commutators sliding off needs to be controlled, the positioning plate can be rotated to a horizontal angle first, and then according to the number of commutators to be collected, the auxiliary shedding mechanism can be used to drive the push block to align with the gap between adjacent commutators, drive the push block to extend into the gap between adjacent commutators, and then drive the push block to move from back to front, so that the commutator sleeved on the positioning plate can be pushed off, thereby realizing the control of the number of commutators removed at a single time, and then adapting to different collection containers to meet different transportation needs.

[0019] 2. The turning device for commutator surface finishing described in the present invention drives the commutator to rotate forward and reverse during the cutting process. By changing the cutting direction, the contact mode and cutting force between the tool and the commutator surface are changed. This change helps to reduce vibration and friction during the cutting process, thereby reducing the generation of burrs and improving the roundness of the commutator.

A motor 2 10 is fixedly connected to one side of the upper end surface of the adjustment frame 11, and the output end of the motor 2 10 is fixedly connected to the end of the brush roller 3.

A motor 5 33 is fixedly connected to the upper end face of the slide block 26, and a threaded rod 2 34 is fixedly connected to the output end of the motor 5 33.

[0032] The workbench 1 is also provided with an auxiliary disengagement mechanism for disengaging the commutator from the positioning plate 5, the auxiliary disengagement mechanism includes a slide plate 6 fixedly connected to one side of the front end of the workbench 1, a threaded block 30 is slidably connected to the inner side of the slide plate 6, and sliding rods 35 are slidably connected to both sides of the upper end of the threaded block 30, and a push block 31 is fixedly connected to the upper end of the sliding rod 35.

[0034] One side of the front end surface of the threaded block 30 is fixedly connected with an electric push rod 5 32 , and the piston end of the electric push rod 5 32 is fixedly connected to one side of the push block 31 .

[0035] Specifically, since the commutator is composed of many commutator segments, these commutator segments are usually evenly distributed along the circumference of the commutator, and there are gaps between the commutator segments. This even distribution can ensure that the flow of current in the winding is smoothly reversed. When the existing commutator surface finishing device is used, a certain amount of metal debris will be generated due to the friction and cutting action between the tool and the commutator surface, and these debris may remain in the commutator segment gaps. The residue of the debris will affect the flatness of the commutator surface, resulting in a decrease in motor performance, and even cause a short circuit between the commutator segments, causing motor failure; Therefore, in order to solve the above problems, when the present embodiment is used, after the commutator is positioned, the electric push rod 4 23 is used to drive the slide block 26 to move, so that the turning tool 25 contacts the commutator surface, and then the motor 3 19 drives the rotating seat 16 to rotate, so that the commutator can be rotated, and the turning tool 25 can be used to perform precision turning on the commutator surface. At the same time, the motor 5 33 can be used to drive the threaded rod 2 34 to rotate, so that the turning tool 25 can be moved up and down to change the turning position; In addition, since the cutting process of the commutator is intermittent cutting, it is easy to form windmill-shaped burrs at the notch. Therefore, in order to reduce this kind of burrs, the commutator can be driven to rotate forward and reverse during the cutting process. By changing the cutting direction, the contact mode between the tool and the commutator surface and the cutting force will change. This change helps to reduce the vibration and friction during the cutting process, thereby reducing the generation of burrs and improving the roundness of the commutator. When the turning of a commutator is completed, the adjusting frame 11 can be driven by the electric push rod 12 to move horizontally, so that the bristles of the brush roller 3 can be inserted into the commutator segment gap of the commutator. At the same time, the brush roller 3 can be driven by the motor 2 10 to rotate, so that the debris in the commutator segment gap can be cleaned to remove the debris. In addition, the commutator can be driven to rotate to make the bristles extend into the gaps of the commutator segments at different positions, thereby achieving comprehensive cleaning of the debris in the commutator segment gaps, avoiding the situation that the commutator surface flatness is affected due to the debris remaining in the commutator segment gap, and then the motor performance is reduced, or even the commutator segments are short-circuited, causing the motor failure; In some cases, it is necessary to turn multiple commutators. If the brush roller 3 is used to clean the debris in the gap of the commutator segments after turning of each commutator is completed, the working frequency of the brush roller 3 will increase, which will also affect the subsequent turning work and reduce the turning efficiency. Therefore, in order to solve this problem, when it is necessary to turn multiple commutators in sequence, each time a commutator is turned, the electric push rod 22 will drive the support block 21 to slide on the positioning plate 5, so that the support block 21 retracts to the inside of the positioning plate 5, and drives the positioning plates 5 to approach each other, so that the commutator falls downward and is stacked on the placement tray 4. When a certain number of commutators are accumulated on the placement tray 4, the electric push rod 22 is used to move the support block 21 to the inner side of the positioning plate 5. The rod 6 27 drives the plug-in rod 9 to move laterally and approach the stacked commutator. The plug-in rod 9 will be squeezed with the commutator segments and inserted into the gaps between the commutator segments. At this time, the placement plate 4 is driven to rotate, and the plug-in rod 9 will resist the commutator segments and block the rotation of the commutator until all the commutator segments overlap and all the commutators are at the same angle. At this time, the positioning plate 5 is used to fix all the commutators, and then the brush roller 3 is driven to extend into the gaps of the commutator segments, so that the bristles can be extended into the gaps of the commutator segments of all commutators, and then the above cleaning work is repeated, thereby realizing the unified removal of debris from the gaps of all commutator segments, thereby reducing the working frequency of the brush roller 3 and improving the turning efficiency. Since a plurality of commutators are neatly stacked on the placement tray 4, the commutators that have been turned can also be stored, which is beneficial to the subsequent unified collection and transportation of the commutators. When the commutator on the placement tray 4 needs to be removed, the motor 20 can be used to drive the adjustment plate 18 to rotate to tilt the positioning plate 5, so that the commutator can slide off the positioning plate 5 and then be collected. In some cases, the commutator needs to slide into a collection container for collection, and different collection containers can accommodate different numbers of commutators. Therefore, in order to better adapt to the collection container and meet the transportation needs, it is necessary to collect the commutators that fall into the collection container. To control the number of commutators in the collection container, the positioning plate 5 can be rotated to a horizontal angle first, and then according to the number of commutators to be collected, the motor 7 is used to drive the threaded rod 29 to rotate, so that the threaded block 30 slides and the push block 31 is aligned with the gap between adjacent commutators. The push block 31 is driven to rise by the electric push rod 32 so that the push block 31 extends into the gap between adjacent commutators, and then the push block 31 is driven to move from back to front, so that the commutator sleeved on the positioning plate 5 can be pushed off, thereby realizing the control of the number of commutators removed at a single time, and then it can adapt to different collection containers and meet different transportation needs.

[0036] Working principle: The inner hole of the commutator to be turned is sleeved on the outside of the positioning plate 5, and the electric push rod 3 22 is used to drive the support block 21 to slide, so that the support block 21 moves to the outside of the positioning plate 5, and a bulge is formed on the surface of the positioning plate 5 to support the bottom of the commutator. At the same time, the electric push rod 2 14 is used to drive the positioning plate 5 on one side to slide, and under the cooperation of the connecting rod 1 15 and the connecting rod 2 17, multiple positioning plates 5 can slide radially at the same time until the positioning plate 5 fits with the inner hole wall of the commutator, so that the commutator can be fixed, so that different inner holes can be The commutator of the hole diameter plays a positioning effect, thereby ensuring the stability of the commutator during the turning process, and it is not easy to deviate. When the commutator is positioned, the electric push rod 4 23 is used to drive the slide block 26 to move, so that the turning tool 25 contacts the commutator surface, and then under the action of the motor 3 19, the rotating seat 16 is driven to rotate, so that the commutator can be rotated, and the turning tool 25 can be used to perform precision turning on the commutator surface. At the same time, the motor 5 33 can be used to drive the threaded rod 2 34 to rotate, so that the turning tool 25 moves up and down to change the turning position; and Since the cutting process of the commutator is intermittent cutting, it is easy to form windmill-shaped burrs at the notch. Therefore, in order to reduce this kind of burrs, the commutator can be driven to rotate forward and reverse during the cutting process. By changing the cutting direction, the contact mode between the tool and the commutator surface and the cutting force change. This change helps to reduce the vibration and friction during the cutting process, thereby reducing the generation of burrs and improving the roundness of the commutator. When a commutator is turned, the electric push rod 12 can be used to drive the adjustment frame 11 to move horizontally to make the brush The brush hairs of roller 3 extend into the gaps of the commutator segments. At the same time, the brush roller 3 is driven by motor 2 10 to rotate, so that the debris in the gaps of the commutator segments can be cleaned to remove the debris. Moreover, the commutator can be driven to rotate so that the brush hairs extend into the gaps of the commutator segments at different positions, thereby achieving comprehensive cleaning of the debris in the gaps of the commutator segments, thus avoiding the situation that the flatness of the commutator surface is affected due to the debris remaining in the gaps of the commutator segments, and then the motor performance is reduced, or even the commutator segments are short-circuited, causing the motor to fail.In some cases, it is necessary to turn multiple commutators. If the brush roller 3 is used to clean the debris at the gap of the commutator segments after turning of each commutator, the working frequency of the brush roller 3 will increase, which will also affect the subsequent turning work and reduce the turning efficiency. Therefore, in order to solve this problem, when it is necessary to turn multiple commutators in sequence, each time a commutator is turned, the electric push rod 22 will drive the support block 21 to slide on the positioning plate 5, so that the support block 21 is retracted to the inside of the positioning plate 5, and the positioning plates 5 are driven to approach each other, so that the commutator falls downward and is stacked on the placement tray 4. When the placement tray 4 is After a certain number of commutators are accumulated, the electric push rod 6 27 is used to drive the plug-in rod 9 to move horizontally and approach the stacked commutators. The plug-in rod 9 will be squeezed with the commutator segments and inserted into the gaps between the commutator segments. At this time, the placement plate 4 is driven to rotate, and the plug-in rod 9 will resist the commutator segments and block the rotation of the commutator until all the commutator segments overlap and all the commutators are at the same angle. At this time, the positioning plate 5 is used to fix all the commutators, and then the brush roller 3 is driven to extend into the gaps of the commutator segments, so that the bristles can be extended into the gaps of the commutator segments of all commutators, and then the above cleaning work is repeated, thereby achieving cleaning of all the commutator segment gaps. The debris in the gap is uniformly cleared, thereby reducing the working frequency of the brush roller 3 and improving the turning efficiency; and because a plurality of commutators are neatly stacked on the placement tray 4, the commutators that have been turned are also stored, which is conducive to the subsequent unified collection and transportation of the commutators. When the commutator on the placement tray 4 needs to be removed, the motor 20 can be used to drive the adjustment plate 18 to rotate, so that the positioning plate 5 is tilted, so that the commutator can slide off the positioning plate 5 and then be collected; and in some cases, the commutator needs to slide into the collection container for collection, and different collection containers have different accommodating quantities of commutators. Therefore, in order to better adapt to the collection Container, to meet the transportation needs, if the number of commutators falling into the collection container needs to be controlled, the positioning plate 5 can be rotated to a horizontal angle first, and then the threaded rod 29 is driven to rotate by the motor 7 according to the number of commutators to be collected, so that the threaded block 30 slides, and the push block 31 is aligned with the gap between adjacent commutators, and the push rod 5 32 is used to drive the push block 31 to rise, so that the push block 31 extends into the gap between adjacent commutators, and then the push block 31 is driven to move from the back to the front, so that the commutator sleeved on the positioning plate 5 can be pushed down, thereby realizing the control of the number of commutators removed at a single time, and then it can adapt to different collection containers and meet different transportation needs. ;
