Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing equipment technology, specifically to a magnetic steel sheet grinding and polishing machine. Background Technology

[0002] Grinding and polishing are crucial steps in the production and processing of magnetic steel sheets. The smoothness and precision of the magnetic steel sheet surface have a direct and significant impact on its subsequent performance. High-quality grinding and polishing can improve the magnetic properties of the magnetic steel sheet, reduce magnetic loss, and enhance its corrosion resistance and service life, enabling it to exhibit superior performance in many fields such as motors and electronic equipment.

[0003] Existing magnetic steel sheet grinding and polishing equipment has several limitations. Some equipment uses a fixed grinding and polishing chamber structure, resulting in insufficient and uneven contact between the magnetic steel sheet and the abrasive during the grinding and polishing process. This leads to low grinding and polishing efficiency, requiring a longer processing time to achieve the desired surface quality, thus increasing production costs. Moreover, due to the lack of effective abrasive agitation, excessive wear or accumulation of abrasive in certain areas can easily occur, further affecting the consistency of the grinding and polishing effect and resulting in inconsistent surface quality of the processed magnetic steel sheets. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a magnetic steel sheet grinding and polishing machine that promotes the rotation of the grinding and polishing chamber through a designed drive mechanism, thereby promoting the flow and tumbling of the internal abrasive and improving grinding and polishing efficiency.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides a magnetic steel sheet grinding and polishing machine, comprising:

[0006] A base on which an inclined pivot is rotatably mounted via a ball joint.

[0007] A grinding and polishing chamber is mounted on a rotating shaft. The top of the grinding and polishing chamber is open, and a protruding material distribution cone is provided at the center of the inner cavity of the grinding and polishing chamber.

[0008] The drive mechanism, located within the base, includes a tilt limiting component and a rotation component. The tilt limiting component is used to maintain the tilt state of the rotating shaft, and the rotation component is used to drive the rotating shaft to rotate around the ball joint seat.

[0009] Preferably, the tilting limiting assembly includes a fixing ring fixedly installed in the base, the axis of the fixing ring being collinear with the axis of the ball joint seat, the fixing ring being located between the polishing chamber and the ball joint seat, and the rotating shaft passing through the inside of the fixing ring.

[0010] Preferably, a first bevel gear is fixed on the fixed ring, and a second bevel gear is fixed on the rotating shaft. The second bevel gear is located above the first bevel gear and meshes with the first bevel gear.

[0011] Preferably, the rotating assembly includes:

[0012] A limiting ring is rotatably mounted inside the base, and the axis of the limiting ring is collinear with the axis of the ball joint seat.

[0013] A rotating sleeve, which is rotatably mounted on a rotating shaft;

[0014] The inner wall of the limiting ring is provided with a slot, and the outer wall of the rotating sleeve is fixed with a card plate, which is inserted into the slot.

[0015] Preferably, a toothed ring is fixed on the outer wall of the limiting ring, a reduction motor is provided inside the base, and a gear that meshes with the toothed ring is sleeved on the output shaft of the reduction motor.

[0016] Preferably, the bottom of the grinding and polishing chamber is provided with a conical recess corresponding to the material distribution cone, and a bottom plate covering the conical recess is fixed to the bottom of the grinding and polishing chamber. The rotating shaft is perpendicular to the bottom plate and passes through the bottom plate, and the end of the rotating shaft away from the ball joint seat is inserted into the conical recess.

[0017] Preferably, a vibration motor is fixed on the base plate, and a buffer structure is provided between the rotating shaft and the polishing chamber.

[0018] Preferably, the buffer structure includes an elastic plug and an elastic sleeve. The elastic plug is located in the conical recess and sleeved on the top of the rotating shaft. The elastic sleeve is sleeved on the rotating shaft, and the bottom plate is sleeved on the elastic sleeve.

[0019] Preferably, the polishing chamber is provided with an annular abrasive cavity, and the bottom of the abrasive cavity is curved.

[0020] Preferably, the bottom of the grinding and polishing chamber is provided with a discharge port, and the discharge port is provided with a cover.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention features an inclined rotating shaft mounted on a base via a ball joint, with the polishing chamber positioned on the shaft. This tilting of the polishing chamber, driven by a rotating assembly, causes the polishing chamber to oscillate around the ball joint, continuously agitating the abrasive within and polishing the magnetic steel sheet. By incorporating a fixed ring, a first bevel gear, and a second bevel gear, the second bevel gear rolls on the first bevel gear as the shaft rotates, thus enabling the polishing chamber to rotate simultaneously around the axis of the ball joint, continuously oscillating. The mechanism promotes abrasive tumbling. A limiting ring and a rotating sleeve are used. The limiting ring rotates under the drive of a geared motor. Since a retaining plate is fixed to the rotating sleeve and inserted into the slot of the limiting ring, the limiting ring rotates along with the rotating sleeve, thereby driving the rotating shaft to rotate around the axis of the limiting ring. The shaft's rotation is achieved through the meshing of the first and second bevel gears. A vibration motor installed on the base promotes abrasive tumbling in the polishing chamber, improving polishing efficiency. The buffer structure reduces vibration, minimizing the impact of the vibration motor on the drive mechanism. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] like Figures 1 to 6 As shown in Embodiment 1 of this utility model, a magnetic steel sheet grinding and polishing machine is provided. Its structure mainly includes a base 1, a grinding and polishing chamber 4, and a drive mechanism. The base 1 serves as the supporting foundation for the entire device. A ball joint seat 2 is fixedly installed at the center of its bottom, and a rotating shaft 3 is rotatably mounted on the ball joint seat 2. Because the ball joint seat 2 allows the rotating shaft 3 to swing around the ball joint seat 2, the rotating shaft 3 will tilt. This tilting arrangement causes the grinding and polishing chamber 4, after being installed on the rotating shaft 3, to also have a certain degree of tilt. The top of the grinding and polishing chamber 4 is open, facilitating the placement of the magnetic steel sheet and abrasive. A protruding material distribution cone 5 is provided at the center of the inner cavity. The function of the material distribution cone 5 is to evenly disperse the abrasive, improving the grinding and polishing effect, and also facilitating the circulation of the abrasive within the grinding and polishing chamber 4. The grinding and polishing chamber 4 has an annular abrasive cavity, and the bottom of the abrasive cavity is curved. This curved surface design allows the abrasive to flow and tumble better within the abrasive cavity, preventing the abrasive from getting stuck, increasing the contact area and time between the magnetic steel sheet and the abrasive, and improving the grinding and polishing effect. Meanwhile, a discharge port is provided at the bottom of the grinding and polishing chamber 4, and a cover 19 is provided at the discharge port. After the grinding and polishing work is completed, the cover 19 is opened, and the abrasive and the processed magnetic steel sheet can be discharged through the discharge port for easy cleaning and collection.

[0035] like Figure 4 As shown, the drive mechanism is housed within the base 1 and comprises two parts: a tilt limiting component and a rotation component. The tilt limiting component includes a fixed ring 6, which is fixedly installed within the base 1. The axis of the fixed ring 6 is collinear with the axis of the ball joint seat 2. Since the fixed ring 6 is located between the polishing chamber 4 and the ball joint seat 2, and the rotating shaft 3 passes through the inside of the fixed ring 6, when the rotating shaft 3 tilts under gravity, it will press against the fixed ring 6 and be supported by it, thus maintaining the tilt angle of the rotating shaft 3.

[0036] This utility model also includes a first bevel gear 7, coaxial with the fixed ring 6, fixed on the fixed ring 6, and a second bevel gear 8 fixed on the rotating shaft 3. From Figure 4 As can be seen, the second bevel gear 8 is located above the first bevel gear 7 and meshes with it. Therefore, when the shaft 3 rotates actively, the second bevel gear 8 will roll on the first bevel gear 7. This allows the polishing chamber 4 to rotate around the axis of the ball joint seat 2 while rotating, constantly oscillating and promoting the tumbling of the abrasive, thereby fully polishing the magnetic steel sheet. If the shaft 3 does not have the power to rotate actively, but is driven to oscillate around the ball joint seat 2, it will also passively rotate due to the meshing relationship between the second bevel gear 8 and the first bevel gear 7.

[0037] Example 2:

[0038] Based on Embodiment 1, in order to drive the rotating shaft 3 to rotate, the rotating assembly designed in this utility model includes a limiting ring 9 rotatably mounted in the base 1 via a slewing bearing and a rotating sleeve 10 rotatably mounted on the rotating shaft 3. The axis of the limiting ring 9 is collinear with the axis of the ball joint seat 2, and a groove 11 extending radially along the limiting ring 9 is formed on the inner sidewall of the limiting ring 9. A retaining plate 12 is fixed on the outer wall of the rotating sleeve 10, and the retaining plate 12 is movably inserted into the groove 11.

[0039] Meanwhile, a geared ring 13 is fixed to the outer wall of the limiting ring 9, and a geared motor (not shown in the attached drawing) is fixedly installed inside the base 1. A gear meshing with the geared ring 13 is fitted onto the output shaft of the geared motor. When the geared motor operates, it drives the geared ring 13 to rotate via the gear, thereby causing the limiting ring 9 to rotate. Because the retaining plate 12 is inserted into the retaining slot 11, the limiting ring 9 rotates along with the rotating sleeve 10, ultimately causing the rotating shaft 3 to oscillate and rotate around the axis of the limiting ring 9.

[0040] This embodiment achieves the swaying and rotation of the polishing chamber 4 through the above structure, which effectively promotes the tumbling of the abrasive and improves the polishing effect of the magnetic steel sheet.

[0041] Example 3:

[0042] Based on Embodiments 1 and 2, Embodiment 3 of this utility model further optimizes the structure of the polishing chamber 4. Firstly, since the polishing chamber 4 has a thin-walled structure, its bottom has a conical recess 14 corresponding to the shape of the material distribution cone 5. The end of the rotating shaft 3 furthest from the ball joint seat 2 is inserted into the conical recess 14. To better bear the load and increase the stability of the polishing chamber 4, a base plate 15 covering the conical recess 14 is fixed to the bottom of the polishing chamber 4. The rotating shaft 3 is perpendicular to and passes through the base plate 15. The cooperation between the base plate 15 and the rotating shaft 3 further enhances the reliability of the connection between the polishing chamber 4 and the rotating shaft 3.

[0043] To further improve polishing efficiency, a vibratory motor 16 is fixed on the base plate 15. When the vibratory motor 16 operates, it generates vibration, promoting the tumbling of the abrasive in the polishing chamber 4, ensuring full contact between the magnet and the abrasive, and improving polishing efficiency. However, the vibration generated by the vibratory motor 16 may affect the drive mechanism; therefore, a buffer structure is provided between the rotating shaft 3 and the polishing chamber 4. Figure 4 As shown, the buffer structure includes an elastic plug 17 and an elastic sleeve 18. The elastic plug 17 is fitted onto the top of the rotating shaft 3 and inserted into the conical recess 14. The elastic sleeve 18 is fitted onto the rotating shaft 3 and located between the base plate 15 and the rotating shaft 3. The base plate 15 is fitted onto the elastic sleeve 18. Since the grinding and polishing chamber 4 is in contact with the rotating shaft 3 through the elastic plug 17 and the elastic sleeve 18, the elastic plug 17 and the elastic sleeve 18 can absorb the vibration generated by the vibration motor 16, reduce the vibration transmitted to the rotating shaft 3, reduce the impact on the drive mechanism, and ensure the stable operation of the drive mechanism.

[0044] This embodiment further improves the grinding and polishing efficiency of the magnetic steel sheet and the stability of the device by optimizing the structure of the grinding and polishing chamber 4 and adding a vibration motor 16 and a buffer structure.

[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
