Description

Technical Field

[0001] This utility model relates to the field of modular rotor lamination technology, specifically to a modular rotor lamination leveling device. Background Technology

[0002] As one of the core components of a motor, the assembly accuracy of the modular rotor laminations directly affects the motor's operating performance and service life. During the assembly process, problems such as uneven end faces and improper installation of the fixing pins often occur when pressing the stator workpiece body and the fixing pins together, leading to uneven air gaps, increased electromagnetic noise, and even affecting the overall reliability of the machine.

[0003] Currently, the industry mostly adopts a step-by-step operation method for the leveling of modular rotor laminations: first, the main body of the stator workpiece is pressed and leveled, and then the fixing pin is pressed in.

[0004] However, this method has the following shortcomings: First, traditional equipment lacks an effective positioning and fixing structure, making the workpiece prone to displacement during the clamping process, affecting the flatness accuracy. Figure 6 As shown, this type of modular rotor lamination has a complex configuration, and it is difficult to achieve precise positioning and reliable fixation during processing using existing technologies. Secondly, it is difficult to unload the workpiece after it has been flattened, and manual assistance is often required to remove it, which is inefficient and poses safety hazards. Finally, the step-by-step operation requires multiple clamping and equipment switching, which not only results in low work efficiency but also easily affects the quality of the finished product due to repeated positioning errors.

[0005] In addition, conventional pressing mechanisms mostly use a single pressing method, which is difficult to adapt to the process requirements of pre-flattening and final pressing of the modular rotor laminations during the pressing process, which can easily lead to uneven pressing of the fixing pins or deformation of the workpiece.

[0006] Based on this, the present invention designs a modular rotor lamination leveling device to solve the above problems. Utility Model Content

[0024] The upper edge of the placement block 6 is chamfered, which is beneficial for picking up and placing the main body 7 of the modular rotor lamination.

[0032] The switching assembly includes a drive pulley 44, a drive belt 45, and a connecting block 46.

One end of the connecting block 46 is fixedly connected to the moving block 41 at the end near the drive pulley 44, and the other end of the connecting block 46 is fixedly connected to the drive belt 45.

[0033] The housing of motor 47 is fixedly connected to the lower end of base plate 1, and the output end of motor 47 is fixedly connected to a set of transmission pulleys 44.

[0034] The substrate 1 has an ejection clearance hole 48 for avoiding the ejection mechanism 5.

[0035] The ejection mechanism 5 includes an ejection cylinder 51, a connecting plate 52, an ejection block 53, an L-shaped connecting plate 54, and an ejection guide rail 55. The ejection guide rail 55 is fixedly connected to the side wall of the ejection clearance hole 48. The L-shaped connecting plate 54 is slidably connected to the ejection guide rail 55 via a slider.

[0036] The moving block 41 and the placing block 6 are provided with a top-out block clearance hole 61.

[0037] In this invention, the modular rotor lamination workpiece body 7, pre-installed with fixing pins 71, is transferred to a set of placement blocks 6 by a robotic arm or manually. The motor 47 starts, and with the cooperation of the station switching slide rail 43, transmission pulley 44, transmission belt 45, and connecting block 46, it drives the moving block 41 and handle 42 below the placement block 6 to move backward until the set of placement blocks 6 reaches below the gantry 2. At this point, the motor 47 stops, and the downward pushing cylinder 31 on the gantry 2 starts, pushing the fixing plate 32 downward. The flattening plate 38 first contacts the modular rotor lamination workpiece body 7, pre-flattening the modular rotor lamination workpiece body 7. Subsequently, as the fixed plate 32 continues to move downward, the spring 34 on the limiting post 33 is compressed, and the spring 34 acts as a buffer. At this time, the ejector pin 36 on the ejector pin fixing block 35 enters the ejector pin clearance hole 37. During the downward movement, the ejector pin 36 pre-flattens the fixing pin 71 until the ejector pin fixing block 35 abuts against the flat plate 38. At this time, the downward push cylinder 31 stops. After holding for a period of time, the main body 7 of the modular rotor lamination workpiece and the fixing pin 71 can be pressed and flattened. After the pressing and flattening is completed, the downward push cylinder 31 is started, and the fixed plate 32, the limiting post 33, the spring 34, the ejector pin fixing block 35, the ejector pin 36 and the flat plate 38 are reset. When one set of placement blocks 6 reaches below the gantry 2, with the cooperation of the transmission pulley 44, the transmission belt 45 and the connecting block 46, another set of placement blocks 6 reaches the front end of the base plate 1. At this time, one set of placement blocks 6 is pressing and leveling the modular rotor lamination workpiece body 7 and the fixing pin 71. At this time, the modular rotor lamination workpiece body 7 with the fixing pin 71 pre-installed can be transferred to the other set of placement blocks 6 by a robotic arm or manually. By repeating the above process, the dual-station alternating pressing and leveling of the modular rotor lamination workpiece body 7 and the fixing pin 71 can be realized, which improves work efficiency. When the placement block 6 reaches the front end of the substrate 1, with the cooperation of the ejection guide rail 55 and the L-shaped connecting plate 54, the ejection cylinder 51 also reaches the front end of the substrate 1. At this time, the ejection cylinder 51 is activated, pushing the connecting plate 52 and the ejection block 53 to move upward, thereby ejecting the block-type rotor lamination workpiece body 7 and the fixing pin 71 that have been pressed and leveled upward, making it convenient for the robotic arm or manual unloading.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
