Description

Technical Field

[0001] The present application relates to the technical field of rotor core processing, and in particular to a rotor core shaping device. Background Art

[0002] The rotor core is part of the motor magnetic circuit, and together with the stator core and the air gap, it constitutes the entire magnetic circuit of the motor. The rotor core is made of multiple silicon steel sheets stacked together. When forming the rotor core, it will go through a stamping, shaping and a second stamping in sequence. Among them, shaping is to correct the shape and size of the rotor core. After the rotor core is stamped once, it will be transported to the shaping equipment through a conveyor rack and shaped in sequence;

[0003] The shaping equipment mainly includes a conveyor platform supporting the rotor core, a shaping rod and a pushing cylinder installed on the conveyor platform. The output end of the pushing cylinder extends out to push the rotor core to the bottom of the shaping rod, and then returns to the initial position. After the shaping of the rotor core is completed, the next rotor core is pushed to the bottom of the shaping rod. However, when the rotor core is being shaped, the subsequent rotor core to be shaped has not passed the limit and may slide, interfering with the shaping rod that is shaping the rotor core at this time. Utility Model Content

[0004] The present application provides a rotor core shaping device, which can constrain and fix a rotor core to be subsequently shaped when the rotor core is being shaped, thereby ensuring the stable operation of the shaping device.

[0005] The present application provides a rotor core shaping device that adopts the following technical solution:

[0006] A rotor core shaping device comprises a conveying platform for supporting the core and a shaping assembly mounted on the conveying platform, wherein a driving assembly for driving the rotor core to move is mounted on the bottom side of the conveying platform, and the driving assembly comprises a driving disc, a cam and a vertically arranged material blocking rod;

[0007] A notch and a movable opening for the movement of the material blocking rod are provided on the conveying platform, and the driving disc partially extends into the notch. The driving disc and the cam are spaced apart and connected with a gear transmission, and the peripheral side wall of the cam contacts the end of the material blocking rod and drives the material blocking rod to move vertically.

[0008] By adopting the above technical scheme, when the rotor core is shaped by the shaping assembly, the cylinder will push the next rotor core to be shaped, so that the shaped rotor core is pushed to the notch by the rotor core to be shaped, and the driving disc at the notch continues to rotate, driving the shaped rotor core to move to the next processing unit, and when the driving disc continues to rotate, the blocking rod will move vertically, so that the blocking rod can timely block the second rotor core to be shaped and perform subsequent release actions. By setting up a driving assembly, not only can the shaped rotor core be transported, but also the subsequent rotor core to be shaped can be limited synchronously, which has a higher degree of automation and ensures the stable operation of the shaping equipment.

[0009] Optionally, a connecting ring plate is arranged at intervals on the bottom side of the conveying platform, and the connecting ring plate is connected to the material blocking rod. A first elastic element is sleeved on the material blocking rod, and one end of the first elastic element abuts against the connecting ring plate, and the other end of the first elastic element abuts against the conveying platform.

[0010] By adopting the above technical solution, the rotation of the driving disc further drives the cam to rotate. During the rotation process, the cam lifts the stop rod, and the stop rod extends out of the movable opening and blocks the rotor core. At this time, the first elastic element contracts and the cam continues to rotate. At this time, the first elastic element rebounds and the stop rod retreats. By setting the first elastic element, the end of the stop rod can always be in contact with the peripheral side wall of the cam, and the stop rod can also withdraw from the movable opening more quickly.

[0011] Optionally, a movable groove is formed around the peripheral side wall of the cam, and a movable ball is connected to one end of the material blocking rod close to the cam and extends into the movable groove.

[0012] By adopting the above technical solution, the movable groove can better limit the material stop rod, prevent the material stop rod from deviating during movement, and make the movement more stable. The movable ball reduces the friction between the material stop rod and the cam, thereby providing better protection for both the cam and the material stop rod.

[0013] Optionally, the shaping assembly includes a shaping seat and a vertically arranged shaping rod, the shaping seat is installed on the conveying platform, and the shaping rod is rotatably connected to the shaping seat and can move vertically.

[0014] By adopting the above technical solution, when the rotor core is pushed to the bottom of the shaping rod, the shaping rod moves vertically downward and extends into the center hole of the rotor core to trim the rotor core so that the steel sheets constituting the rotor core can be stacked together more neatly.

[0015] Optionally, a through hole for the shaping rod to pass through is opened on the conveying platform, and the through hole is coaxially arranged with the shaping rod.

[0016] By adopting the above technical solution, the through hole can avoid the shaping rod when it moves vertically downward, preventing the shaping rod from causing damage to the conveying platform when shaping the rotor core.

[0017] Optionally, a first limit plate and a second limit plate are connected to the conveying platform, and the first limit plate and the second limit plate are spaced apart and combined with the conveying platform to form a limit channel for the rotor core to move.

[0018] By adopting the above technical solution, the first limiting plate and the second limiting plate constrain the movement trajectory of the rotor core, preventing the rotor core from shifting in position after being pushed, which would make it difficult for the shaping component to operate normally.

[0019] Optionally, a limit assembly for limiting the position of the rotor core is further included, the limit assembly is installed on the conveying platform, and includes a driving cylinder and a fixed plate, the output end of the driving cylinder is connected to the fixed plate and pushes the fixed plate to move, and the first limit plate is provided with an avoidance opening for avoiding the fixed plate.

[0020] By adopting the above technical solution, when the rotor core is being shaped, the driving cylinder pushes the limit plate forward and abuts against the rotor core, thereby fixing the rotor core and enabling the shaping rod to cooperate with the rotor core more smoothly, thereby ensuring smooth progress of the shaping work.

[0021] Optionally, the fixing plate is arranged in an arc shape on a side facing away from the driving cylinder, an arc-shaped groove is provided on the second limiting plate, and the fixing plate and the groove wall of the arc-shaped groove enclose a fixing cavity for fixing the rotor core.

[0022] By adopting the above technical solution, the shape of the fixing cavity can better match the shape of the rotor core, and the rotor core can be fixed firmly.

[0023] Optionally, a ejection port connected to the arc groove is formed on the second limiting plate, the ejection port is formed in a step-like shape and is provided with an ejection piece for ejecting the rotor core, the ejection piece includes a ejection rod and a second elastic element, one end of the second elastic element is connected to the end of the ejection rod, and the other end of the second elastic element is connected to the step surface of the ejection port.

[0024] By adopting the above technical solution, when the driving cylinder pushes the fixed plate forward, the ejector rod will abut against the peripheral side wall of the rotor core and eventually retreat, so that the rotor core abuts against the arc groove. When the rotor core is shaped, the fixed plate retreats, and the contracted second elastic element rebounds to push the rotor core out of the arc groove, which is convenient for subsequent transportation.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The present application is provided with a driving assembly, which can synchronously block and transport the rotor core. When the rotor core is shaped by the shaping assembly, the cylinder will push the next rotor core to be shaped, so that the shaped rotor core is pushed to the notch by the rotor core to be shaped, and the driving disk at the notch continues to rotate, driving the shaped rotor core to move to the next processing unit, and when the driving disk continues to rotate, the blocking rod will move vertically, so that the blocking rod can timely block the second rotor core to be shaped and perform subsequent release actions. By setting up the driving assembly, not only the shaped rotor core can be transported, but also the subsequent rotor core to be shaped can be limited synchronously, and the degree of automation is higher.

[0027] 2. In the present application, a limit assembly is provided to fix the rotor core. When the rotor core is being shaped, the driving cylinder pushes the limit plate forward to abut against the rotor core, thereby fixing the rotor core and enabling the shaping rod to cooperate with the rotor core more smoothly, thereby ensuring smooth progress of the shaping work.

[0028] 3. In the present application, a ejector is provided to push the shaped rotor core out of the arc groove. When the driving cylinder pushes the fixed plate forward, the ejector rod will abut against the peripheral side wall of the rotor core and eventually retreat, so that the rotor core abuts against the arc groove. When the shaping of the rotor core is completed, the fixed plate retreats, and the contracted second elastic element rebounds to push the rotor core out of the arc groove, which is convenient for subsequent transportation.

[0045] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0046] A rotor core shaping device, referring to Figure 1 , including a conveying platform 1 for supporting the iron core and a shaping component 2 installed on the conveying platform 1, the conveying platform 1 is connected with a first limiting plate 4 and a second limiting plate 5, the first limiting plate 4 and the second limiting plate 5 are arranged at intervals and combined with the conveying platform 1 to form a limiting channel 6 for the movement of the rotor iron core.

[0047] After the rotor core is stamped once, it will be transferred to the limiting channel 6. Specifically, it also includes a transfer frame 10 for transferring the core rotor. The transfer frame 10 is tilted as a whole and one end is connected to the conveying platform 1. When the rotor core is located on the transfer frame 10, it will slide toward the conveying platform 1 under the action of its own gravity. Correspondingly, a plurality of conveying rollers 20 are rotatably connected to the transfer frame 10. The conveying rollers 20 are evenly arranged in sequence along the length direction of the transfer frame 10 to facilitate the sliding of the rotor core.

[0048] In addition, a blocking cylinder 30 for blocking the rotor core is horizontally arranged on the transmission frame 10. The blocking cylinder 30 is connected to one side of the transmission frame 10 and a baffle 40 is provided on the output end. When the output end of the blocking cylinder 30 is extended, the baffle 40 blocks the rotor core, so that the rotor core enters the limiting channel 6 one by one and in an orderly manner.

[0049] Reference Figure 1 , in order to distinguish the direction, the end of the conveying platform 1 connected to the transmission frame 10 is named the starting end 14, and the other end of the conveying platform 1 is named the terminal end 15. When the rotor core enters the limiting channel 6 from the rotor core, the rotor core is located at the starting end 14;

[0050] A pushing cylinder 60 is provided at the starting end 14 and is fixedly connected to the conveying platform 1 by bolts. When the output end of the pushing cylinder 60 extends out, the rotor core is pushed to the shaping component 2 so that the shaping component 2 can shape the rotor core.

[0051] Reference Figure 1 The shaping assembly 2 includes a shaping seat 21 and a vertically arranged shaping rod 22. The shaping seat 21 is fixedly installed on the conveying platform 1 by bolts. The shaping rod 22 is rotatably connected to the shaping seat 21 and can move vertically. When the rotor core is pushed to the shaping assembly 2, the shaping rod 22 moves downward and extends into the center hole of the rotor core to trim the rotor core so that the steel sheets constituting the rotor core can be more neatly stacked together. Furthermore, a through hole 13 is provided on the conveying platform 1 for the shaping rod 22 to pass through. The through hole 13 is coaxially arranged with the shaping rod 22 and the aperture of the through hole 13 is larger than the outer diameter of the shaping rod 22 to avoid the downward movement of the shaping rod 22.

[0052] In addition, a blowing pipe 50 is fixedly connected to the conveying platform 1. The blowing pipe 50 is arranged in a winding manner and its output end faces the avoidance opening 41. After the rotor core is fixed, the output end of the blowing pipe 50 outputs air flow to the rotor core to clean the rotor core.

[0053] Furthermore, a counterweight block 23 is sleeved on the outer end of the shaping rod 22. By adding the counterweight, the shaping rod 22 is guaranteed to rotate stably and the shaping rod 22 is prevented from deviating during the rotation process.

[0054] It should be noted that a distance is maintained between the bottom surface of the counterweight block 23 and the end surface of the shaping rod 22, and the distance is greater than the thickness of the rotor core to avoid collision between the counterweight block 23 and the rotor core when the shaping rod 22 is shaping the rotor core.

[0055] Combination Figure 2 and Figure 3, and also includes a limit assembly 8 for limiting the rotor core. The limit assembly 8 is installed on the conveying platform 1. When the rotor core is pushed below the limit rod, the limit assembly 8 fixes the rotor core. The limit assembly 8 includes a driving cylinder 81 and a fixing plate 82. The output end of the driving cylinder 81 is inserted into the fixing plate 82 and is detachably connected to the fixing plate 82 by screws. When the output end of the driving cylinder 81 extends forward, the fixing plate 82 is pushed. Correspondingly, an avoidance opening 41 for avoiding the fixing plate 82 is opened on the first fixing plate 82, so that the fixing plate 82 can extend into the limiting channel 6.

[0056] Furthermore, in order to clamp the core rotor more firmly, the fixing plate 82 is arranged in an arc shape on one side facing away from the driving cylinder 81, and the second limiting plate 5 is provided with an arc groove 51. The fixing plate 82 and the groove wall of the arc groove 51 enclose a fixing cavity 7 for fixing the rotor core. When the rotor core is shaped, the circumferential side surface of the rotor core will respectively abut against the groove wall of the arc groove 51 and the arc surface of the fixing plate 82 under the push of the limiting assembly 8, thereby fixing the rotor core.

[0057] The second limiting plate 5 is provided with a ejection opening 52 which is connected with the arc groove 51. The ejection opening 52 is provided in a step shape and is provided with an ejection piece 9 for ejecting the rotor core. The ejection piece 9 includes an ejection rod 91 and a second elastic element 92. One end of the second elastic element 92 abuts against the end of the ejection rod 91, and the other end of the second elastic element 92 abuts against the step surface of the ejection opening 52.

[0058] Under normal circumstances, the end of the ejector rod 91 extends out of the arc groove 51, and when the fixed plate 82 is pressed against the rotor core, the ejector rod 91 retracts and the second elastic element 92 located in the ejection port 52 contracts. When the rotor core is completed and the fixed plate 82 withdraws from the limiting channel 6, the second elastic element 92 rebounds and the ejector rod 91 pushes the rotor core out of the arc groove 51.

[0059] Reference Figure 4 and Figure 5 A driving assembly 3 for driving the rotor core to move is installed on the bottom side of the conveying platform 1. The driving assembly 3 includes a driving disc 31, a cam 32 and a vertically arranged material blocking rod 33, wherein the driving disc 31 and the cam 32 are both rotatably connected to the bottom side of the conveying platform 1, and a movable groove 321 is opened around the side wall of the cam 32. A movable ball 34 is connected to the end of the material blocking rod 33 close to the cam 32 and extends into the movable groove 321.

[0060] Furthermore, a notch 11 and a movable opening 12 for the movement of the material blocking rod 33 are provided on the conveying platform 1. The notch 11, the through hole 13 and the movable opening 12 are arranged in sequence along the length direction of the first limiting plate 4, wherein the notch 11 is closest to the starting end 14, and the driving disc 31 partially extends into the notch 11. The driving disc 31 and the cam 32 are spaced apart and connected by gear transmission. The peripheral side wall of the cam 32 contacts the end of the material blocking rod 33 and drives the material blocking rod 33 to move vertically.

[0061] When the rotor core is shaped by the shaping assembly 2, the pushing cylinder 60 will push the next rotor core to be shaped, so that the shaped rotor core is pushed to the notch 11 by the rotor core to be shaped, and the driving disk 31 at the notch 11 continues to rotate, driving the shaped rotor core to move to the next processing unit, and when the driving disk 31 continues to rotate, the blocking rod 33 will move vertically, so that the blocking rod 33 can timely block the second rotor core to be shaped and perform subsequent release actions.

[0062] Furthermore, a connecting ring plate 35 is arranged at intervals on the bottom side of the conveyor platform 1. The connecting ring plate 35 is fixedly connected to the material stopping rod 33 and is integrally formed with the material stopping rod 33. A first elastic element 36 is sleeved on the material stopping rod 33. One end of the first elastic element 36 abuts against the connecting ring plate 35, and the other end of the first elastic element 36 abuts against the bottom surface of the conveyor platform 1.

[0063] During the movement of the cam 32, the first elastic element 36 will shrink or rebound accordingly, so that the end of the material blocking plate is always in contact with the peripheral side of the cam 32, ensuring that the material blocking rod 33 can respond in time according to the rotation state of the cam 32 and extend or retract from the movable opening 12.

[0064] The implementation principle of the embodiment of the present application is:

[0065] After the rotor core is stamped once, it will slide from the transmission frame 10 and enter the conveying platform 1. When a rotor core enters the limiting channel 6, the blocking cylinder 30 on the transmission frame 10 will extend to block the rotor core still on the transmission frame 10. At this time, the rotor core in the limiting channel 6 will be pushed to the through hole 13 by the pushing cylinder 60. After the rotor core is fixed by the limiting assembly 8, the shaping rod 22 will extend into the center hole to shape the rotor core.

[0066] After the rotor core is pushed to the through hole 13 and the output end of the pushing cylinder 60 retreats, the output end of the blocking cylinder 30 also retreats, allowing the second rotor core to enter the limiting channel 6, and the blocking rod 33 extends from the movable opening 12 to block the second rotor core, preventing the rotor core from sliding and interfering with the first rotor core being shaped at this time. After the shaping of the first rotor core is completed, the blocking rod 33 also descends to release the second rotor core;

[0067] At this time, the output end of the push cylinder 60 extends forward, and continues to push the second rotor core to the through hole 13, and the first rotor core originally at the through hole 13 is pushed by the first rotor core, moves to the driving disk 31, and is driven by the driving disk 31 to enter the next processing unit.

[0068] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
