Description

Technical Field

[0001] This utility model relates to the field of motor stator and rotor core production technology, specifically to an automatic flattening device for motor stator and rotor cores that facilitates material discharge. Background Technology

[0002] In the motor manufacturing industry, the manufacturing quality of the motor stator and rotor cores directly affects the overall performance and operating efficiency of the motor. Although the traditional stamping and leveling process for motor stator and rotor cores can effectively improve the flatness and dimensional accuracy of the cores, the cores often stick to the stamping table after stamping and leveling. This not only affects the continuous operation of the production line, but also increases the complexity and time cost of manual cleaning.

[0003] Specifically, after the existing stamping and leveling equipment completes the stamping and leveling of the iron core, the iron core parts are often difficult to separate smoothly from the stamping table due to factors such as the friction generated during the stamping and leveling process, the adhesion of the material itself, and the microscopic unevenness of the stamping table surface. This adhesion phenomenon not only leads to a decrease in production efficiency, as operators need to frequently interrupt production to manually remove the adhered iron cores, but may also cause scratches or deformation on the surface of the iron core during the removal process, thereby affecting its electrical performance and mechanical strength.

[0004] Chinese Patent Publication No. CN117811292A discloses an automatic flattening and shaping device for motor stator and rotor cores. The device uses a driving component to drive a pressing plate to flatten the upper surface of the core product, while simultaneously using a first lifting mechanism to move the support platform upward, achieving bidirectional flattening of the core product. This not only reduces processing steps and improves actual flattening efficiency, but also enhances the flattening effect of motor stator and rotor core products, thus benefiting enterprise production efficiency.

[0005] However, in actual use, when the motor stator and rotor cores are tightly adhered to the stamping table, the telescopic cylinders activated may encounter significant resistance when attempting to push the motor rotor out of the stamping flattening area. This causes additional wear on the telescopic cylinders themselves, shortening their service life. More seriously, if the motor stator and rotor cores cannot be pushed out smoothly, it may cause production line interruptions, requiring manual intervention to clean the stamping table, which will further increase production costs and reduce production efficiency. Utility Model Content

Through the coordinated operation of the stamping unit and the automatic ejection unit, the problem of motor stator and rotor cores adhering to the stamping table after stamping and flattening is solved.

Detailed Implementation

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1-3 As shown, an automatic flattening device for motor stator and rotor cores that facilitates material discharge includes a base 1, a housing 2 on the base 1, and a feeding unit 3 on the top of the base 1 near the housing 2 for conveying the motor rotor to be processed; the device is characterized in that a stamping unit 4 for stamping the motor stator and rotor core to be processed is provided inside the housing 2 at the top of the housing 2, the stamping unit 4 includes a stamping flattening seat 41 on the right side of the housing 2 and a stamping table 42 for stamping the motor stator and rotor core to be processed, and an automatic ejection unit 5 for ejecting the stamped and flattened motor stator and rotor core is also provided inside the housing 2.

[0028] The stamping unit 4 also includes a telescopic cylinder 43, a stamping block 44, and a limiting rod 45. The telescopic cylinder 43 is mounted on the housing 2. The output end of the telescopic cylinder 43 is connected to the stamping flat seat 41. The stamping flat seat 41 is provided with a stamping block 44. The stamping table 42 is provided with a stamping groove that is clearance-fitted with the stamping block 44. There are four limiting rods 45 and they are fixedly installed inside the housing 2. All four limiting rods 45 are located above the stamping table 42. The stamping flat seat 41 is clearance-fitted with the limiting rods 45. When the motor stator and rotor cores need to be stamped and flattened, the telescopic cylinder 43 is activated, driving the stamping and flattening seat 41 to move closer to the stamping table 42 along the setting direction of the limiting rod 45 until the stamping block 44 is set on the stamping and flattening seat 41 to stamp and flatten the motor stator and rotor cores in the stamping table 42. During this process, the automatic ejection unit 5 does not eject the motor stator and rotor cores. After the stamping and flattening is completed and the stamping and flattening seat 41 rises, the automatic ejection unit 5 can eject the stamped motor stator and rotor cores.

[0029] See Figures 3-5As shown, the automatic ejection unit 5 includes a mounting base 51, a sliding block 52, and a hinge rod 53. The mounting base 51 has a pair symmetrically arranged on the stamping flat seat 41, and the mounting base 51 is located above the stamping table 42. The sliding block 52 has a pair and is slidably arranged on the stamping table 42 and the housing 2 respectively. When the stamping flat seat 41 descends, the sliding block 52 is in a sliding state. One end of the hinge rod 53 is rotatably connected to the mounting base 51, and the other end of the hinge rod 53 is rotatably connected to the sliding block 52. When the stamping flat seat 41 descends, the hinge rod 53 is in an inclined state.

[0030] When the stamping flattening base 41 descends, the sliding block 52, which is rotatably connected by the hinge rod 53, can slide away from the stamping table 42. When the stamping flattening base 41 finishes stamping and rises, the sliding block 52 can be driven by the hinge rod 53 to move into the stamping table 42.

[0031] See Figures 5-7 As shown, the automatic ejection unit 5 also includes a limiting slide rail 54 and an ejection block 55; the limiting slide rail 54 has a pair and is respectively disposed in the housing 2, and the limiting slide rail 54 is close to the side of the stamping table 42, and the limiting slide rail 54 and the sliding block 52 are in clearance fit; the ejection block 55 is disposed between the sliding blocks 52 and is fixedly connected to the sliding blocks 52.

[0032] When the sliding block 52 slides, it can slide horizontally in a straight line under the restriction of the sliding rail 54, making the sliding of the sliding block 52 more stable. The ejector block 55 is coated with a release agent, so that the ejector block 55 can apply the release agent to the stamping table 42 each time it is pushed. This reduces the friction between the motor stator and rotor core and the stamping table 42 when the ejector block 55 ejects the motor stator and rotor core during the next stamping and flattening of the motor stator and rotor core. When the sliding block 52 slides, it can drive the ejector block 55, which is fixedly installed with it, to move, so as to automatically eject the stamped and flattened motor stator and rotor core in the stamping table 42 and reduce the friction between the motor stator and rotor core and the stamping table 42.

[0033] See Figure 6 As shown, the automatic ejection unit 5 also includes a discharge port 56; the discharge port 56 is opened on the stamping table 42, and the discharge port 56 is used to discharge the stamped and flattened motor stator and rotor cores.

[0034] After being stamped and flattened, the motor stator and rotor core is pushed out by the ejector block 55 and falls onto the conveyor device 551 through the discharge port 56. The automatic ejection unit 5 also includes a conveyor device 551 set on the stamping table 42 for conveying the stamped and flattened motor stator and rotor core. The conveyor device 551 is a synchronous conveyor belt in the prior art, which can promptly convey the stamped and flattened motor stator and rotor core, preventing the motor stator and rotor core from remaining in the stamping table 42 during the next stamping.

[0035] See Figures 6-8 As shown, the feeding unit 3 includes a feeding tray 31, a feeding frame 32, a setting plate 33, and a first pressing roller 34; the feeding tray 31 is set on the base 1 and is located away from the machine housing 2; the feeding frame 32 is set on the base 1 and is located between the feeding tray 31 and the machine housing 2; the setting plate 33 is set above the feeding frame 32; and the first pressing roller 34 is slidably mounted on the setting plate 33.

[0036] The motor stator and rotor cores are fed through the feeding tray 31. The feeding tray 31 is equipped with a rotary driver for driving the feeding tray 31 to rotate. The rotary driver drives the feeding tray 31 to stably transport the motor stator and rotor cores on the feeding frame 32. During the transport of the motor stator and rotor cores, the first pressing roller 34 can limit the motor stator and rotor cores during the transport process. The first pressing roller 34 can rotate when it contacts the motor stator and rotor cores, which can reduce the friction and contact damage to the motor stator and rotor cores during the transport process and prevent the motor stator and rotor cores from deviating during transport.

[0037] See Figure 8 As shown, the feeding unit 3 also includes a linear driver 35, a lead screw 36, a sliding seat 37, and a second pressing roller 38; the linear driver 35 is mounted on the setting plate 33 and located above the first pressing roller 34; the lead screw 36 is located at the output end of the linear driver 35; the sliding seat 37 is slidably mounted on the setting plate 33 and threadedly connected to the lead screw 36; the second pressing roller 38 is located on the feeding frame 32 and located on one side of the first pressing roller 34.

[0038] When the position of the first clamping roller 34 needs to be adjusted, the linear driver 35 is started and drives the lead screw 36 to rotate. When the lead screw 36 rotates, it drives the sliding seat 37 to slide in a horizontal linear direction. When the sliding seat 37 slides, it drives the fixedly connected first clamping roller 34 to move closer to the position of the second clamping roller 38. This allows the motor stator and rotor core being conveyed to be pressed between the first clamping roller 34 and the second clamping roller 38, ensuring the stability of the motor stator and rotor core during the conveying process. It also limits the contact between the two sides of the motor stator and rotor cores of different widths.

[0039] Working principle: During the stamping and leveling process of the motor stator and rotor core, the telescopic cylinder 43 is activated first, driving the stamping and leveling seat 41 to move along the direction of the limiting rod 45 towards the stamping table 42 until the stamping block 44 levels the motor stator and rotor core. During this process, the hinge rod 53 drives the sliding block 52 to slide horizontally along the limiting slide rail 54, away from the stamping table 42. After stamping is completed, the stamping and leveling seat 41 rises, and the hinge rod 53 drives the sliding block 52 to move towards the stamping table 42. The ejection block 55 on the sliding block 52 is coated with a release agent to reduce the friction between the motor stator and rotor core and the stamping table 42, and automatically ejects the stamped and leveled motor stator and rotor core to the discharge port 56 during sliding. The motor stator and rotor core then falls onto the conveying device 551. The conveying device 551 is a synchronous conveyor belt to ensure that the motor stator and rotor core is removed in time to avoid interfering with the next stamping. The motor stator and rotor core is fed through the feeding tray 31 and driven to rotate by the rotary driver to achieve stable conveying. The first clamping roller 34 limits the movement of the motor stator and rotor cores during transport and can rotate to reduce friction and damage. If the position of the first clamping roller 34 needs to be adjusted, the linear driver 35 is activated, driving the lead screw 36 to rotate, causing the sliding seat 37 to move the first clamping roller 34 closer to the second clamping roller 38, thereby stabilizing the transport of motor stator and rotor cores of different widths.

[0040] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
