Description

Technical Field

[0001] This utility model relates to the field of rotor lamination processing technology, specifically to an auxiliary feeding structure for rotor laminations. Background Technology

[0002] In the manufacturing process of motor rotors, the stamping and forming of rotor laminations is one of the core processes. The efficiency and stability of lamination feeding directly affect the overall production rhythm. Currently, the industry mainly uses two methods for feeding rotor laminations: manual feeding and simple mechanical pushing feeding. The pain points of manual material feeding: Operators need to place the stacked rotor laminations one by one into the stamping die, which is not only labor-intensive and costly, but also prone to positioning deviations due to human error, leading to an increase in stamping scrap rate; at the same time, manual material feeding needs to be synchronized with the stamping equipment, which poses a safety hazard of hands accidentally entering the stamping area, and does not meet the safety standards of modern production. Pain points of simple mechanical push-feeding: Existing mechanical structures mostly use a single cylinder for pushing, lacking a clamping and limiting mechanism for the laminations. When laminations are stacked, problems such as lateral tilting and misalignment are prone to occur, causing laminations to fall off during the pushing process, requiring frequent machine stops for adjustment, which seriously affects production efficiency; in addition, traditional pushing structures cannot adapt to rotor laminations of different sizes, have poor versatility, and require re-adjustment of the equipment when changing product models, increasing production preparation time. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a rotor lamination auxiliary feeding structure, which has the advantages of automatic clamping and limiting, stable pushing, and adaptability to laminations of multiple sizes. It solves the problems of low efficiency and high safety hazards of traditional manual feeding, as well as poor stability and insufficient versatility of simple mechanical feeding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotor lamination auxiliary feeding structure, including a base plate, with support legs fixedly installed at the four corners of the bottom of the base plate, a support frame fixedly installed on the left side of the base plate, a cross limiting plate fixedly installed on the top right side of the support frame, lamination clamping plates provided at the four corners of the bottom of the cross limiting plate, and a lamination adapter support mechanism, which is set on the top of the cross limiting plate and used to clamp and limit multiple sets of longitudinally placed laminations; The support clamping drive mechanism is located on the side of the support frame near the cross limit plate and is used to drive the punch fitting support mechanism. The stamping pushing mechanism is located on the front side of the base plate and is used to push the stamping pieces on the top of the base plate from the left to the right stamping die for processing.

[0005] In a preferred embodiment of this invention, the lamination fitting support mechanism includes a rotating disk, an arc-shaped drive groove, a slider, and a toggle post.

The top of the lamination clamping plate is fixedly mounted to the bottom of the slider. The toggle post is fixedly mounted on the top of the slider and slides in cooperation with the arc-shaped drive groove.

[0006] As a preferred embodiment of this utility model, the supporting and clamping drive mechanism includes a servo motor, a gear, and a gear ring. The servo motor is fixedly installed on the top right side of the support frame via a bracket. The output end of the servo motor is fixedly installed with the gear. The gear ring is fixedly installed on the outer surface of the rotating disk, and the gear ring meshes with the gear.

[0007] As a preferred embodiment of this utility model, the stamping pushing mechanism includes a cylinder, a feeding plate, and a fixing frame.

[0009] As a preferred embodiment of this utility model, a limiting shaft is fixedly installed inside the cross-shaped limiting plate, and a sliding hole that slides with the limiting shaft is provided inside the slider.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0019] Example 1 Reference Figure 1-3 This is the first embodiment of the present utility model, which adopts the following technical solution, including a base plate 1, with support legs 3 fixedly installed at the four corners of the bottom of the base plate 1, a support frame 6 fixedly installed on the left side of the base plate 1, a cross limiting plate 42 fixedly installed on the top right side of the support frame 6, and punch clamping plates 46 provided at the four corners of the bottom of the cross limiting plate 42. It also includes a punch adapter support mechanism, which is set on the top of the cross limiting plate 42 and is used to clamp and limit multiple sets of longitudinally placed punches. The punch adapter support mechanism includes a rotating disk 4, an arc-shaped drive groove 41, a slider 43 and a toggle post 44. The rotating disk 4 is rotatably installed at the top center of the cross limiting plate 42 by a shaft pin. The arc-shaped drive groove 41 is opened inside the rotating disk 4 and is distributed in a ring at equal distances. The slider 43 is slidably installed inside the cross limiting plate 42. The top of the punch clamping plate 46 is fixedly installed with the bottom of the slider 43. The toggle post 44 is fixedly installed on the top of the slider 43 and slides with the arc-shaped drive groove 41. The support clamping drive mechanism is located on the side of the support frame 6 near the cross limit plate 42 and is used to drive the punch fitting support mechanism. The stamping pushing mechanism is located on the front side of the base plate 1 and is used to push the stamping pieces on the top of the base plate 1 from the left to the right stamping die for processing.

[0020] Specifically, after the supporting clamping drive mechanism drives the rotating disk 4 to rotate, it can move the actuating column 44 to the top of the cross limit plate 42 inward and outward through the arc-shaped drive groove 41 on the rotating disk 4. Then, the actuating column 44 drives the slider 43 to slide inside the cross limit plate 42. In turn, the slider 43 drives the lamination clamping plate 46 to slide to the outer surface of the rotor lamination, and limit and support the rotor lamination. This makes it easy for the rotor laminations stacked inside the lamination clamping plate 46 to be wrapped and stably stored. When the bottom rotor lamination is moved away by the feeding plate 21, a new rotor lamination can fall with its own weight to wait for the feeding operation.

[0021] Example 2 The second embodiment of this utility model adopts the following technical solution: the supporting clamping drive mechanism includes a servo motor 5, a gear 51, and a gear ring 52. The servo motor 5 is fixedly installed on the top right side of the support frame 6 through a bracket. The output end of the servo motor 5 is fixedly installed with the gear 51. The gear ring 52 is fixedly installed on the outer surface of the rotating disk 4. The gear ring 52 and the gear 51 mesh with each other. The stamping pushing mechanism includes a cylinder 2, a feeding plate 21, and a fixing frame 22. The fixing frame 22 is fixedly installed on both sides of the cylinder 2, and its back is fixedly installed with the base plate 1. The feeding plate 21 is fixedly installed on the output end of the cylinder 2. The bottom of the feeding plate 21 is slidably engaged with the top of the base plate 1. The feeding plate 21 is located at the bottom of the stamping clamping plate 46.

[0022] Specifically, the servo motor 5 can be stably driven after being fixed by the support frame 6. After the servo motor 5 is started, it can drive the gear 51 to rotate. The gear 51 drives the gear ring 52 that meshes with it to rotate. Then, the gear ring 52 drives the rotating disk 4 to rotate, so that the rotating disk 4 achieves the driving effect. The cylinder 2 can be fixed on the front side of the base plate 1 by the fixing frame 22. When the cylinder 2 is started, it can drive the feeding plate 21 to push the rotor punch from below the punch clamp 46 to the right side of the base plate 1, so that the rotor punch to be processed can be moved to the stamping die for processing.

[0023] Example 3 In the second embodiment of this utility model, the following technical solution is adopted: a support arc frame 7 is fixedly connected to the side of the feeding plate 21 near the punch clamp 46, a temporary storage plate 71 is fixedly connected to the side of the feeding plate 21 away from the punch clamp 46, a limit shaft 45 is fixedly installed inside the cross limit plate 42, and a sliding hole 451 that slides with the limit shaft 45 is opened inside the slider 43.

[0024] Specifically, the support arc frame 7 prevents the rotor laminations pushed by the feed plate 21 from falling back and forth. At the same time, when the feed plate 21 moves to the right side of the base plate 1, the temporary storage plate 71 prevents the rotor laminations temporarily stored inside the lamination clamp 46 from immediately falling to the top of the base plate 1. The temporary storage plate 71 allows the rotor laminations inside the lamination clamp 46 to fall down and wait for the next feeding operation after the feed plate 21 moves to the left limit position. The limiting shaft 45 can cooperate with the sliding hole 451 to slide and limit the slider 43 to prevent the slider 43 from falling down when sliding inside the cross limiting plate 42, thereby improving the stability of the slider 43 sliding to drive the lamination clamp 46.

[0025] Working principle: This rotor lamination auxiliary feeding structure achieves stable temporary storage, precise clamping, and efficient pushing of laminations through the coordinated operation of a lamination adapter support mechanism, a support clamping drive mechanism, and a lamination pushing mechanism. The specific process is as follows: First, in the initial preparation stage, multiple sets of longitudinally stacked rotor laminations are placed in the area of ​​the base plate 1 below the cross-shaped limiting plate 42, ensuring the bottom of the laminations is in contact with the top of the feeding plate 21. Then, the support clamping drive mechanism is activated, with the support frame 6 driving the output gear 51 to rotate via a servo motor 5 fixed to the bracket. The gear 51 meshes with the gear ring 52 on the outer surface of the rotating disk 4, thereby driving the rotating disk 4 to rotate around the central shaft pin at the top of the cross-shaped limiting plate 42; entering the lamination clamping limit... After the positioning stage, as the rotating disk 4 rotates, the arc-shaped drive grooves 41 distributed equidistantly inside it rotate synchronously. The arc-shaped drive grooves 41 slide and engage with the actuating post 44 on the top of the slider 43, pushing the actuating post 44 to move inward. The slider 43 is slidably connected to the limiting shaft 45 in the cross limiting plate 42 through the internal sliding hole 451. Driven by the actuating post 44, it slides inward along the limiting shaft 45, thereby driving the lamination clamping plate 46 at the bottom of the slider 43 to move inward synchronously until the lamination clamping plate 46 fits against the outer surface of the rotor lamination, completing the annular clamping and limiting of the stacked laminations to prevent the laminations from tilting to the side. At the same time, the limiting shaft 45 can prevent the slider 43 from falling downward when sliding, ensuring clamping. Stability; Next, the stamping pushing stage begins. The cylinder 2, fixed to the front of the base plate 1 by the two side fixing brackets 22, is activated in the stamping pushing mechanism. The output end of the cylinder 2 drives the feeding plate 21 to slide along the top of the base plate 1 towards the right side of the stamping die. The supporting arc frame 7 on the left side of the feeding plate 21 fits against the front and rear sides of the stamping to prevent the stamping from falling off during the pushing process. The feeding plate 21 pushes the bottom rotor stamping away from below the stamping clamping plate 46 and moves it to the right side of the base plate 1. When the feeding plate 21 moves to the right limit position of the base plate 1, the stamping is pushed above the stamping die to complete the loading. At this time, the temporary storage plate 71 on the right side of the feeding plate 21 moves to directly below the cross limit plate 42, receiving the stacked stampings above. To prevent the laminations from falling prematurely onto the base plate 1, the cylinder 2 drives the feeding plate 21 to reset to the left after the stamping equipment completes the lamination processing. The temporary storage plate 71 moves away from below the cross limit plate 42 along with the feeding plate 21. The stacked laminations fall to the top of the base plate 1 under their own weight and fit against the feeding plate 21. If the lamination size needs to be changed, the rotation direction of the servo motor 5 can be adjusted to drive the rotating disk 4 to rotate in the opposite direction, so that the lamination clamping plate 46 moves outward to expand the clamping range, adapting to the new size laminations without replacing equipment parts, improving versatility. Then, the above "clamping-pushing-resetting" process is repeated to realize the continuous automated feeding of rotor laminations.

[0026] In summary, by coordinating the base plate, support legs, support frame, cross limit plate, lamination clamping plate, lamination adapter support mechanism, support clamping drive mechanism, and lamination pushing mechanism, continuous automated feeding of rotor laminations is achieved, reducing manual labor intensity and safety risks, while also preventing laminations from tipping over or falling during the pushing process, thus reducing downtime for adjustment.
