Description

Technical Field

[0001] This utility model relates to the field of commutator processing, specifically a commutator riveting and reinforcing ring device. Background Technology

[0002] The commutator consists of several commutator segments arranged in a cylindrical shape. The segments are secured by elastic bands after being arranged on a plastic sleeve. The inner hooks of the commutator segments form an annular groove. To maintain the shape of the commutator segments after arrangement, reinforcing rings are placed inside the annular grooves and the inner hooks are riveted to lock the reinforcing rings within the grooves, thus ensuring the commutator segments retain their cylindrical shape.

[0003] The existing commutator reinforcing ring riveting equipment has several problems: First, the upper reinforcing ring is pushed by a mold, which has poor stability, and when the size of the reinforcing ring changes, the specifications of the pushing mold must also be changed accordingly, which takes up time; Second, the riveting mechanism mainly uses the riveting head to press the inner hook, causing the inner hook to deform. However, the deformation caused by frontal extrusion is small and cannot completely lock the reinforcing ring. The probability of the reinforcing ring detaching from the inner hook is high, which leads to the commutator segments in the array becoming loose. Utility Model Content

[0004] In view of the technical problems existing in the background art, the technical problem solved by this utility model is to provide a commutator riveting and reinforcing ring device with stable upper reinforcing ring and good riveting effect.

[0009] The pneumatic support claw extends into the reinforcing ring at the ring-removing station, then inflates and expands, securing the reinforcing ring outside the claw. The claw then moves to the ring-adding station, stops inflating, deflates and retracts, and the reinforcing ring detaches from the claw and is placed at the ring-adding station. After completing the reinforcing ring delivery, the pneumatic support claw moves back to the ring-removing station. The pneumatic support claw's outer diameter after expansion is adjusted by the amount of air inflated, making it suitable for reinforcing rings of different specifications. This invention is not only more convenient to use and has higher production efficiency, but also offers better stability.

[0010] Preferably, the commutator conveying mechanism includes a lower support plate, a left clamping plate and a right clamping plate. The left clamping plate and the right clamping plate are provided with several sets of left and right corresponding clamping ports.

[0015] The feeding assembly includes a pusher head that moves back and forth, the pusher head being mounted on a lower support plate and facing the material picking station; the discharge port of the second vibrator is mounted on the lower support plate and in front of the retracted pusher head. The second vibrator feeds the commutator onto the lower support plate, and the pusher head pushes the commutator forward to the material picking station. After feeding is completed, the pusher head resets and receives the next commutator.

[0016] Preferably, the reinforcing ring conveying component is located on the side of the commutator conveying mechanism, the feeding tray is provided with a feeding channel, and the end of the feeding channel is a ring removal station;

[0017] A lower ring-adding station is provided on the side of the upper ring-adding station, and the lower ring-adding station is located on the same side as the reinforcing ring conveying component;

[0018] The first driving component also drives the pneumatic support claw to move between the material picking station and the lower ring adding station, and the pneumatic support claw alternately delivers the reinforcing ring between the upper ring adding station and the lower ring adding station. After the pneumatic support claw delivers the reinforcing ring from the material picking station to the upper ring adding station, the pneumatic support claw returns to the material picking station and picks up the reinforcing ring to deliver it to the lower ring adding station. The next time, the pneumatic support claw delivers the reinforcing ring to the upper ring adding station, and so on, alternatingly feeding materials.

[0019] Preferably, the pneumatic support claw is mounted on a lifting seat, and the lifting seat is connected to a cylinder that drives its lifting and lowering.

[0022] Preferably, the second driving component includes a movable seat, a driving member for moving the movable seat back and forth, a left driving assembly connected to the left clamping plate, and a right driving assembly connected to the right clamping plate.

[0026] The lower riveting assembly includes a lower riveting component, a lower top pressing component, and a lower stop component arranged coaxially. The lower riveting component, the lower top pressing component, and the lower stop component are arranged sequentially from the inside to the outside and the three components slide relative to each other in a vertically sliding manner.

[0027] The upper end of the lower pressing member is the pressing end, and the thickness of the pressing end is narrower than the thickness of the reinforcing ring;

[0028] The riveting end face of the lower riveting member is an inclined surface that slopes downward toward the outer edge;

[0030] The lower pressing component supports the reinforcing ring, while the lower stop component blocks the reinforcing ring from the outside, precisely positioning the reinforcing ring. The upward movement of the lower pressing component pushes the reinforcing ring into the annular groove formed by the inner hook of the commutator segment. The upward movement of the lower riveting component causes the riveting end face to press against the inner hook. Because the upper pressing end is narrower than the reinforcing ring, there is a gap below the reinforcing ring. The riveting end face pushes the inner hook to bend towards the reinforcing ring and place it below the reinforcing ring. After the lower pressing component moves down and resets, the riveted inner hook supports the reinforcing ring and locks it in the annular groove, keeping the commutator cylindrical.

[0031] Preferably, the lower riveting member is mounted on the lower seat, and there is a cavity between the lower end of the lower riveting member and the lower end of the lower stop member.

[0046] The following describes the embodiments and related details and working principle of this utility model with reference to the accompanying drawings. This commutator reinforcing ring riveting device includes a reinforcing ring feeding mechanism 5 and a commutator conveying mechanism 4. The commutator conveying mechanism 4 is provided with an upper ring feeding station 82. The reinforcing ring feeding mechanism 5 includes a reinforcing ring conveying component and a feeding component. The reinforcing ring conveying component includes a first vibrator 52 and a feeding tray 53. The feeding tray is provided with a ring picking station 86. The feeding component includes a vertically lifting pneumatic support claw 51 and a first driving component that drives the pneumatic support claw to move between the ring picking station 86 and the upper ring feeding station 82. The pneumatic support claw 51 is connected to an air source. When the pneumatic support claw retrieves the ring, it is in a retracted state with an outer diameter smaller than the inner hole 121 of the reinforcing ring 12. The pneumatic support claw moves to the ring retrieval position and extends downwards into the reinforcing ring. Then, the pneumatic support claw inflates and expands, fixing the reinforcing ring outside the pneumatic support claw. Afterwards, the pneumatic support claw moves to the upper ring retrieval position, at which point inflation stops, the pneumatic support claw deflates and retracts, and the reinforcing ring detaches from the pneumatic support claw and is placed in the upper ring retrieval position. After completing the reinforcing ring delivery operation, the pneumatic support claw moves back to the ring retrieval position for the next ring retrieval. The pneumatic support claw of this invention adjusts the outer diameter after expansion by adjusting the inflation volume, making it suitable for the needs of reinforcing rings of different specifications.

[0047] The reinforcing ring conveying component is located on the side of the commutator conveying mechanism 4. The feeding tray 53 has a feeding channel 531, the end of which is a ring-retrieving station 86. A lower ring-retrieving station 85 is located on the side of the upper ring-retrieving station, and the lower ring-retrieving station is located on the same side as the reinforcing ring conveying component. The first driving component also drives the pneumatic support claw 51 to move between the picking station 86 and the lower ring-retrieving station 85, and the pneumatic support claw 51 alternately conveys the reinforcing ring 12 between the upper ring-retrieving station and the lower ring-retrieving station. That is, after the pneumatic support claw 51 delivers the reinforcing ring from the picking station 86 to the upper ring-retrieving station 82, the pneumatic support claw returns to the picking station and picks up the reinforcing ring to deliver it to the lower ring-retrieving station 85. The next time, the pneumatic support claw delivers the reinforcing ring to the upper ring-retrieving station, and so on, alternatingly feeding. See Appendix Figure 4 The pneumatic support claw 51 is mounted on a lifting base 54, which is connected to a cylinder 541 that drives its lifting and lowering. The first driving component includes a first guide rail 553, a second guide rail 555, a first cylinder 552 that drives the pneumatic support claw to move linearly between the ring-picking station and the ring-adding station, and a second cylinder 554 that drives the pneumatic support claw to move linearly between the ring-picking station and the ring-adding station. The cylinder is mounted on a first slider 551, which is connected to the first cylinder and slidably disposed on the first guide rail 553. The first cylinder and the first guide rail are mounted on the second slider 554, which is connected to the second cylinder and slidably disposed on the second guide rail 555. The second guide rail and the second cylinder are mounted on the frame. The pneumatic support claw achieves the conveying of the reinforcing ring through horizontal linear movement and lifting and lowering.

[0048] The commutator conveying mechanism includes a lower support plate 62, a left clamping plate 61, and a right clamping plate 63. The left and right clamping plates are provided with several sets of corresponding left and right clamping openings 67. A mold is installed inside each clamping opening, and the mold has an inner hole. Each clamping opening has an inwardly recessed step 671, and the mold is mounted on the step. The mold can be changed according to the size of the commutator, making it suitable for processing commutators of different specifications. The left and right clamping plates 61 and 63 are connected to a second drive component 66 that drives their opening, closing, and forward and backward movement. The lower support plate 62 is positioned below the corresponding clamping opening 67 and is used to support the commutator 1. The second drive component includes a movable seat 661, a drive component 663 that drives the movable seat forward and backward movement, a left drive assembly connected to the left clamping plate, and a right drive assembly connected to the right clamping plate. The left and right drive components have the same structure. The left drive component includes a transverse guide rail 664 and a left drive component 665. At least two transverse guide rails are provided, and the transverse guide rails and the left drive component are mounted on a movable base 661. The left clamping plate 62 is slidably disposed on the transverse guide rails, and the left drive component is connected to the left clamping plate. (See attached image) Figure 3The left drive component uses a cylinder. To prevent the left clamping plate from retracting during riveting, the cylinder is connected to the left clamping plate via a connecting rod assembly 666. The connecting rod assembly is also connected to a movable seat. When the left and right clamping plates are closed, the two connecting rods of the connecting rod assembly, which are respectively connected to the left clamping plate and the movable seat, are in a straight line. The movable seat 661 is fixed in the lateral position on the frame, thus preventing the left clamping plate from retracting. The movable seat is slidably mounted on the longitudinal guide rail 662, which is mounted on the frame. The lower support plate 62 is mounted on the frame, and along the commutator conveying direction, a material picking station 81, an upper ring adding station 82, a lower riveting station 83, and an upper riveting station 84 are sequentially arranged. The lower riveting station corresponding to the lower support plate has a through hole 64 for riveting. A shaping component can also be set at the material picking station. The shaping component includes a pressure plate that moves up and down, pressing down on the commutator to make it aligned vertically. The commutator conveying mechanism further includes a pusher assembly 65 and a second vibrator; the pusher assembly includes a pusher head 651 that moves back and forth, the pusher head is mounted on the lower support plate 62, and the pusher head faces the material picking station 81; the discharge port 652 of the second vibrator is mounted on the lower support plate and is in front of the retracted pusher head. See appendix. Figure 3 The second vibrator delivers the commutator to the lower support plate 62. The left and right clamping plates open, and the pusher head 651 moves forward and pushes the commutator to the material picking station in front. After the feeding is completed, the pusher head resets and receives the next commutator. The left and right clamping plates close to clamp the commutator 1. At this time, each station performs its work. After the work is completed, the left and right clamping plates move forward one position, and the clamped commutator is conveyed forward one position. For example, the commutator at the material picking station moves to the upper ring adding station, and the commutator at the upper ring adding station moves to the lower riveting station. After the conveying is completed, the left and right clamping plates separate, the commutator is released, and then the left and right clamping plates retract and reset, waiting for the next conveying.

[0049] The commutator has an upper hook and a lower hook. The upper hook is fixed by an upper reinforcing ring, and the lower hook is fixed by a lower reinforcing ring. The lower riveting assembly 2 is used to rivet the lower reinforcing ring, and the upper reinforcing ring is riveted by the upper riveting assembly 3.

[0050] The commutator reinforcing ring riveting device further includes a lower riveting assembly 2, an upper riveting assembly 3, a transmission assembly for driving the lower riveting assembly to move between the lower ring-adding station and the lower riveting station, and a first power component 20 for driving the lower riveting assembly to perform riveting operations. The first power component is located at the lower riveting station and is movably coupled with the lower riveting assembly 2. The lower riveting station is also equipped with an upper baffle 8 that moves up and down. During the riveting operation, the upper baffle blocks the commutator. At the lower ring-adding station, the lower riveting assembly 2 receives the reinforcing ring, and at the lower riveting station, it performs the riveting operation.

[0051] The lower riveting assembly 2 includes a coaxially arranged lower riveting member 23, a lower top pressing member 22, and a lower stop member 21. The lower riveting member, lower top pressing member, and lower stop member are arranged sequentially from the inside out and slide relative to each other vertically, i.e., they are nested together. During lifting, adjacent members also serve as guides and limiters, ensuring stable lifting and preventing radial displacement. The upper end of the lower top pressing member 22 is a pressing end 221, and the thickness of the pressing end 221 is narrower than the thickness of the reinforcing ring 12. The riveting end face 231 of the lower riveting member 23 is an inclined surface that slopes downwards towards the outer edge (see attached figure). Figure 9 The outer edge of the riveting end face 231 is the lowest point. During material receiving, the lower stop 21 and the lower top pressing member 22 are stepped. The lower top pressing member is used to support the reinforcing ring, and the lower stop 21 blocks outside the reinforcing ring to accurately position it. The outer edge of the riveting end face 231 is lower than the top pressing end face of the lower top pressing member, and the vertical projection of the reinforcing ring on the lower top pressing member 22 is on the riveting end face 231. The thickness of the top pressing end 221 is narrower than that of the reinforcing ring, and part of the reinforcing ring is suspended, leaving a gap below the reinforcing ring 12. The side of the lower riveting member 23 is close to the lower top pressing member 22, so the outer edge of the riveting end face 231 of the lower riveting member is directly below the reinforcing ring. When the lower riveting member 23 moves upward to squeeze the inner hook, the riveting end face 231 pushes the inner hook 13 to bend towards the reinforcing ring and place it below the reinforcing ring. (See attached figure) Figure 8 After the lower pressing member 22 moves down and resets, the riveted inner hook 13 supports the reinforcing ring 12 and locks the reinforcing ring in the annular groove 14, so that the commutator 1 remains cylindrical.

[0052] The lower riveting assembly 2 further includes a lower seat 24, on which the first power component acts. The lower riveting component 23 is mounted on the lower seat 24, and a cavity 26 is formed between the lower end of the lower riveting component 23 and the lower end of the lower stop component 21. A first spring 27 is provided within the cavity 26, and both ends of the first spring 27 act on the lower pressing component 22 and the lower seat 24. The lower stop component 21 is disposed on the lower seat 24, and a second spring 28 is provided between the lower stop component 21 and the lower seat 24. The lower seat 24 is provided with a mounting groove 29 for the second spring 28 to be inserted. (See attached document) Figure 7The lower end of the lower stop 21 is provided with a boss 211. A limiting seat 25 is fitted over the boss 211 of the lower stop. The limiting seat 25 is connected to the lower seat 24. The elastic force of the second spring 28 acts on the lower stop 21, and the limiting seat 25 blocks the boss 211, so that the lower stop 21 is movably mounted on the lower seat 24. The transmission assembly includes a swing arm 4 and a second power component that drives the swing arm to swing. The swing arm 4 is provided with a plurality of columns 41. The lower seat 24 is hung on the columns 41 and is provided with guide holes that match the columns 41. A return spring 42 is provided between the swing arm 4 and the lower seat 24. At the lower riveting station, the upper baffle moves down to block the commutator. The first power component drives the lower seat 24 to move upward along the column 41. First, the lower stop 21 is blocked by the commutator segment 11, and the second spring 28 is compressed. Then, the lower pressing component 22 pushes the reinforcing ring into the annular groove 14. As the lower seat 24 continues to move upward, the first spring 27 is compressed, and the lower riveting component 23 squeezes the inner hook, causing the inner hook to bend outward and lock the reinforcing ring 12. After the riveting is completed, the first power component retracts, and the elastic force of the return spring 42 causes the lower seat 24 to move downward along the column 41 and return to its original position. The first spring 27 and the second spring 28 respectively push the lower pressing component 22 and the lower stop 21 upward to return to their original positions.

[0053] The lower end of the lower pressing member 22 is thicker than the pressing end 221. The upper and lower ends of the lower pressing member 22 are stepped. The lower riveting member 23 matches the lower pressing member 22. That is, the lower pressing member 22 is narrower at the top and wider at the bottom. This allows the thickness of the pressing end 221 to be narrower than the thickness of the reinforcing ring, while increasing the thickness can improve the strength of the lower pressing member 22. At the same time, a cavity 26 with sufficient width must be provided between the lower end of the lower riveting member 23 and the lower end of the lower stop member 21 to accommodate a thicker spring with a higher elastic coefficient.

[0054] The upper riveting assembly 3 includes an upper pressing member 31 and an upper riveting member 32 coaxially arranged. The upper pressing member 31 is sleeved on the upper riveting member 32, and the two slide in a vertical engagement. The lower end of the upper pressing member 31 is the upper pressing end 311, and the thickness of the upper pressing end 311 is narrower than the thickness of the reinforcing ring. The upper riveting end face 321 of the upper riveting member 32 is an inclined surface that slopes upward towards the outer edge. The outer edge of the upper riveting end face 321 is higher than the upper pressing end face 311 of the lower pressing member 22, and the vertical projection of the upper riveting end face 321 covers part of the reinforcing ring. The upper riveting assembly 3 also includes an upper seat 35, which is connected to a third power member that drives its lifting and lowering. The upper riveting member 32 is disposed on the upper seat 35, and a third spring 33 is provided between the two. The upper pressing member 31 is disposed on the upper seat 35, and a buffer member 34 is provided between the two. The buffer member 34 can be a rubber pad and a spring. During the riveting operation, the commutator is supported by the lower support plate, the third power component drives the upper seat 35 to move downwards, the upper pressing component 31 presses against the reinforcing ring, and the upper riveting end face 321 squeezes the inner hook 13, causing the inner hook to bend outwards and lock the reinforcing ring 12. At this time, the buffer component 34 and the third spring 33 are under pressure. After the riveting is completed, the third power component retracts, driving the upper seat 35 to move upwards, and the buffer component 34 and the third spring 33 respectively push the upper pressing component 31 and the upper riveting component 32 to reset.

[0055] The upper ring-adding station is equipped with an inner sleeve removal component 7, and the upper ring-adding station corresponding to the lower support plate is equipped with a through hole for the inner sleeve to be discharged. The inner sleeve removal component includes a vertically lifting pressing head 71, which is mounted on a second swing arm 72. When the pneumatic support claw 51 delivers the reinforcing ring, the second swing arm 72 swings to make way for the pressing head to deviate from the upper ring-adding station 82, allowing the pneumatic support claw to make room. After the pneumatic support claw completes the ring addition, the second swing arm swings to move the pressing head to the upper ring-adding station, at which point the pressing head is vertically aligned with the commutator inner sleeve at the upper ring-adding station. The pressing head 71 extends into the commutator and presses down on the inner sleeve, causing it to detach from the commutator segment and be discharged through the through hole. If the commutator does not have an inner sleeve and uses an outer sleeve, an outer sleeve removal component is added in front of the upper riveting station. The outer sleeve removal component uses a vertically lifting pressing head, which presses down on the commutator to detach it from the outer sleeve.
