Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor processing equipment technology, and in particular to a motor rotor grinding device. Background Technology
[0002] To secure the guide bars, limiting bars are extended from the rotor body around the rotor's axis of rotation. Symmetrical barbs are provided at the ends of the limiting bars away from the rotor body. The guide bars are positioned between adjacent extensions and are restrained by the barbs from moving away from the rotor body.
[0003] The extension and barbed structure have numerous tiny gaps, making them prone to burr adhesion. These burrs have sharp edges and can easily scratch workers. The burrs can also embed into the contact surfaces of parts, leading to assembly deviations or functional failures. Therefore, it is necessary to remove the burrs from the rotor body. However, manual deburring of transmission components is inefficient and produces inconsistent quality, severely hindering the production efficiency of motor rotors.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0033] The motor rotor grinding device includes an annular seat 2, into which the rotating shaft 73 of the motor rotor 7 can extend. The annular seat 2 supports and restricts the horizontal position of the motor rotor 7. A left fixing block 3 and a right fixing block 4 are positioned above the annular seat 2. The left fixing block 3 and the right fixing block 4 are symmetrically arranged around the axis of the annular seat 2. The left fixing block 3, the right fixing block 4, and the annular seat 2 cooperate to fix the position of the motor rotor 7. The grinding mechanism 6 includes a grinding base 62, a translation seat 64 mounted on the grinding base 62, a lifting seat 66 mounted on the translation seat 64, and a grinding tool 662 mounted on the lifting seat 66. The grinding tool 662 is arranged parallel to the axis of the annular seat 2. The grinding base 62 is connected to the front and rear cylinders 61, the translation seat 64 is connected to the left and right cylinders 63, and the lifting seat 66 is connected to the lifting assembly 65. The front and rear cylinders 61 and the left and right cylinders 63 are arranged vertically, perpendicular to the axis of the annular seat 2. The lifting assembly 65 is arranged along the axis of the annular seat 2. The grinding tool 662 achieves three-dimensional movement through the grinding base 62, the translation seat 64, and the lifting assembly 65. Furthermore, the casting tool is arranged along the axis of the annular seat 2. After the motor rotor 7 is mounted on the annular seat 2, adjusting the position of the grinding tool 662 allows it to easily extend into the gap between the rotor body 71, the extension 72, and the barb 721, efficiently grinding the rotor body 71 and improving the production efficiency of the motor rotor 7.
[0034] It also includes a limiting block 5. A through hole in the center of the annular seat 2 accommodates the rotating shaft 73 of the motor rotor 7. A limiting hole 21 is also provided on the arc surface of the side of the annular seat 2, connecting to the through hole. The limiting block 5 extends into the limiting hole 21 and is connected to a limiting cylinder 52. The limiting block 5, raised into the limiting hole 21, engages with the flat part on the rotating shaft 73, thus restricting the rotation of the motor rotor 7 around the axis of the rotating shaft 73. The limiting cylinder 52 drives the limiting block 5 to move, allowing the limiting block 5 to contact or move away from the rotating shaft 73, thereby restricting the rotation of the motor around the axis of the rotating shaft 73.
[0035] Preferably, a limiting protrusion 51 extends from the limiting block 5. The limiting protrusion 51 extends into the limiting hole 21. A step is formed between the limiting protrusion 51 and the limiting block 5 to limit the length of the protrusion of the limiting block 5 into the limiting hole 21, so as to avoid the limiting protrusion 51 from forcefully squeezing and damaging the rotating shaft 73.
[0036] Along the axis of the annular seat 2, the right fixing block 4 has a first protrusion 41 and a second protrusion 42 symmetrically arranged on the surface of the annular seat 2. Together with the left fixing block 3, the left fixing block 3, the first protrusion 41 and the second protrusion 42 position the motor rotor 7 at three points.
[0037] Preferably, a base plate 1 is also provided. The annular seat 2, the grinding mechanism 6, the left fixing block 3, and the right fixing block 4 are disposed on the base plate 1. A fixing ring 11 is provided on the base plate 1. The fixing ring 11 is used to place and fix the motor rotor 7 on the base plate 1 for temporary storage of the rotor, facilitating loading and unloading.
[0038] More preferably, the annular seat 2, the left fixing block 3, and the right fixing block 4 are each connected to a support base 22. The support base 22 raises the height of the annular seat 2, the left fixing block 3, and the right fixing block 4. By adjusting the height of the support base 22, the height of the annular seat 2, the left fixing block 3, and the right fixing block 4 can be easily adjusted to adjust the fixed position of the motor rotor 7.
[0039] A slide rail 621 is provided on the grinding base 62. The translation seat 64 is slidably connected to the grinding base 62 via the slide rail 621. The left and right cylinders 63 extend and retract, pushing the translation seat 64 to slide along the slide rail 621, thereby adjusting the horizontal position of the grinding tool 662.
[0040] Preferably, the lifting assembly 65 includes a lead screw 653 mounted on the telescopic translation seat 64 and a lifting motor 651 connected to the lead screw 653 via a pulley 652. The lifting seat 66 is connected to the translation seat 64 via the lead screw 653. When the lifting motor 651 is started, it drives the lead screw 653 to rotate via a belt, thereby causing the lifting seat 66 on the lead screw 653 to move up and down.
[0041] More preferably, a rotary motor 661 is provided on the lifting base 66. The rotary motor 661 is connected to the grinding tool 662. The grinding tool 662 is driven to rotate by the rotary motor 661 for grinding.
[0042] In some embodiments, the front and rear cylinders 61 are slide cylinders. Slide cylinders integrate the cylinder body, linear guide rail, limit buffer device, etc., into one unit, requiring less installation space.
[0043] The specific workflow of this utility model is as follows:
[0044] The motor rotor 7 is placed on the annular seat 2, and the rotating shaft 73 extends into the through hole, with the flat part on the rotating shaft 73 facing the limiting hole 21. The limiting cylinder 52 extends, pushing the limiting block 5 to move until the limiting protrusion 51 of the limiting block 5 extends into the limiting hole 21 and contacts the rotating shaft 73. The left telescopic device 31 and the right telescopic device 43 extend synchronously until the left fixed block 3 contacts the rotating shaft 73 and the right fixed block 4 contacts the rotating shaft 73. At this time, the left fixed block 3 and the right fixed block 4 clamp the rotating shaft 73. Finally, the rotary motor 661 starts, and the front and rear cylinders 61, the left and right cylinders 63 and the lifting motor 651 start, driving the grinding tool 662 to move around the motor rotor 7, grinding the rotor body 71, the extension 72 and the barb 721.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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 patent should be determined by the appended claims.
