[0002] As an important component of a motor, the output shaft needs to be ground and polished during the motor manufacturing process to ensure a smooth and flat surface, which also helps to ensure the stability of the output shaft during rotation.

[0003] Currently, the common method for grinding and polishing motor output shafts is to fix a single output shaft in place before grinding. While this method is simple, the fixed area of ​​the output shaft cannot be ground. Therefore, after the first grinding stage, the output shaft needs to be moved and ground again. This not only results in low grinding efficiency but also makes it impossible to grind multiple output shafts simultaneously. Furthermore, repeatedly clamping and loosening the output shaft is inconvenient. Therefore, this solution proposes a grinding and polishing system for motor manufacturing. Summary of the Invention

DETAILED DESCRIPTION

[0040] The application will be further described below in conjunction with the drawings and specific embodiments. It should be noted that the embodiments described below or technical features between the embodiments can be combined to form new embodiments without conflict.

[0041] Embodiment 1:

[0042] Please combine Figures 1-6 The polishing system for motor preparation of the embodiment comprises, in sequence, a feeding station, a first polishing station, a second polishing station and a discharging station. The first polishing station and the second polishing station are both provided with polishing mechanisms. The polishing mechanism comprises a mounting frame 20, a moving plate 22 movably mounted on the outer wall of the mounting frame 20 close to the fixed material mechanism, an extension piece one 21 mounted on the outer wall of the moving plate 22 close to the fixed material mechanism, a polishing plate 23 mounted on the extended end of the extension piece one 21, and an extension piece two 24 mounted on the mounting frame 20 for driving the moving plate 22 to move up and down. The two polishing mechanisms work simultaneously to polish the workpieces on the first polishing station and the second polishing station simultaneously, thereby ensuring the integrity of polishing and polishing of the workpieces.

[0043] The fixed material mechanism comprises a rotating shaft 1, a rotating disc 2 fixed on the top of the rotating shaft 1, and a plurality of material placing assemblies installed on the outer periphery of the rotating disc 2. The rotating shaft 1 is driven to rotate by a servo motor (the servo motor is prior art and is not marked in the text). The servo motor drives the rotating shaft 1 to rotate, so that the fixed material mechanism will stay on the four stations for a period of time before starting again. The material placing assembly comprises a mounting plate 6 fixed on the outer periphery of the rotating disc 2, two movable columns 5 movably mounted on the mounting plate 6, a material falling plate 4 fixed on the bottom of the two movable columns 5, and a plurality of fixed sleeves 16 rotatably connected to the mounting plate 6. The fixed sleeve 16 is provided with a locking piece. The locking piece comprises a plurality of connecting columns 14 movably mounted on the inner wall of the fixed sleeve 16, a clamping block 15 fixed on the end of the connecting column 14 close to the axis of the fixed sleeve 16, and a spring two movably sleeved on the outside of the connecting column 14. The connecting column 14 is arranged along the radial direction of the fixed sleeve 16, and the other end of the connecting column 14 extends to the outside of the fixed sleeve 16 and abuts against the inner wall of the movable sleeve 8. The inner ring of the movable sleeve 8 is divided into a cylindrical portion and a horn-shaped portion, and the horn-shaped portion is located at the bottom of the cylindrical portion. The side with small diameter of the horn-shaped portion is connected with the bottom of the cylindrical portion. When the movable sleeve 8 is pressed down, the connecting column 14 moves along the inner wall of the movable sleeve 8, so as to slide from the end with large diameter of the horn-shaped portion to the end with small diameter, thereby making the connecting column 14 gradually move to the inside of the fixed sleeve 16 during the pressing process of the movable sleeve 8. At this time, the workpiece placed in the fixed sleeve 16 is clamped by the clamping block 15, thereby achieving the purpose of fixing the workpiece.

The diameter of the placement blocks 26 is smaller than the diameter of the workpiece, so as to reduce the rotating resistance of the workpiece during polishing, and to ensure that the polishing plate can polish the bottom edge of the workpiece without touching the blanking plate 4.

[0045] The pressing mechanism includes a fixed plate 7 fixed on the top of the mounting plate 6 by a spring 13 and a plurality of movable sleeves 8 fixed on the fixed plate 7. The plurality of movable sleeves 8 are movably sleeved outside the plurality of fixed sleeves 16. A limiting assembly is arranged between the movable sleeves 8 and the fixed sleeves 16. The limiting assembly includes a limiting block 27 fixed on the outer wall of the fixed sleeve 16 and a limiting groove 28 opened on the inner wall of the movable sleeve 8. The limiting groove 28 is opened along the axial direction of the fixed sleeve 16. One end of the limiting block 27 extends into the limiting groove 28 and is in sliding connection with the limiting groove 28. The limiting assembly enables the movable sleeve 8 to move along the axial direction of the fixed sleeve 16 and also enables the movable sleeve 8 to rotate while the fixed sleeve 16 rotates.

[0046] The transmission mechanism is installed on the fixed plate and is used to drive the plurality of fixed sleeves 16 to rotate simultaneously. The transmission mechanism includes a transmission motor 9 installed on the top surface of the mounting plate 6 and a plurality of linkage gears 10 respectively sleeved outside the plurality of movable sleeves 8. Adjacent two linkage gears 10 are in meshing connection with each other. One end of the output shaft of the transmission motor 9 is fixed with a driving gear 12 in meshing connection with the linkage gears 10.

The two connecting rings are respectively used to connect the two ends of the fixed ring one and the fixed ring two. The axes of the fixed ring one, the fixed ring two and the two connecting rings coincide. The top surfaces of the two connecting rings are inclined upward from the side of the fixed ring one toward the fixed ring two. The bottom of the abutting column 11 abuts against the top surface of the abutting ring 3. The fixed ring one is located directly below the feeding station and the first polishing station. The fixed ring two is located directly below the second polishing station and the discharging station. The abutting ring 3 enables the blanking plate 4 in the blanking assembly to be at different heights in the first polishing station and the second polishing station, so as to automatically lift the height of the blanking plate 4 during the rotation of the rotating shaft 1, and to achieve the purpose of polishing the area of the workpiece that cannot be polished in the first polishing station in the second polishing station.
