Description

Technical Field

[0001] This utility model relates to the technical field of ceramic blank grinding machines, specifically to a daily-use ceramic blank grinding device. Background Technology

[0002] In the production of daily-use ceramics, the polishing process of ceramic blanks is a key step in ensuring the surface quality and exquisite appearance of ceramic products. After the initial shaping of the ceramic blanks, the surface often has problems such as roughness, unevenness, and burrs, which need to be improved by polishing to lay a good foundation for subsequent processes such as glazing and firing.

[0003] Currently, existing daily-use ceramic blank grinding machines on the market have certain limitations in structural design and functional implementation. Among them, the most prominent problem is that the grinding disc in the grinding machine usually rotates horizontally, and the tilt angle of the grinding disc cannot be adjusted up and down during the grinding process. This fixed working method makes the grinding machine lack flexibility when dealing with ceramic blanks of different shapes, sizes, and special surface characteristics.

[0004] In actual production, the shapes of daily-use ceramic blanks are diverse, such as some irregularly shaped ceramic cups and ceramic plates with curves. For these blanks with complex shapes, it is difficult for a horizontally fixed rotating grinding disc to fully and evenly contact all parts of the blank, resulting in some areas being over-polished while others are under-polished, which in turn affects the overall quality and appearance of the ceramic products. In addition, since the grinding disc cannot be adjusted in tilt angle, when dealing with ceramic blanks that require fine polishing in some areas, operators need to frequently adjust the position and angle of the blank. This not only increases the difficulty and workload of operation, but also reduces polishing efficiency. At the same time, it may also cause secondary damage to the blank due to improper operation, increasing the defect rate of the product. Utility Model Content

[0005] The purpose of this invention is to provide a daily-use ceramic blank grinding device to solve the problem that the grinding disc in the existing ceramic blank grinding machine cannot be adjusted in angle.

[0006] This utility model provides the following technical solution: a daily-use ceramic blank grinding device, including a housing, a bearing on the housing, a positioning ring rotatably mounted on the inner wall of the bearing, a fixed circular plate fixedly mounted on the inner wall of the positioning ring, a connecting plate fixedly mounted on the top of the fixed circular plate, and a fixed plate hinged to the end of the connecting plate, a connecting plate fixedly mounted on the inner wall of the fixed plate, and a grinding disc on the inner wall of the connecting plate, a linkage mechanism on the fixed circular plate, the linkage mechanism including an electric push rod, a linkage rod fixedly connected to the electric push rod, and a connecting plate hinged to the linkage rod, and a driving assembly inside the housing for driving the linkage mechanism to rotate.

[0007] As a preferred embodiment of the above technical solution, the linkage mechanism further includes a fixed rod fixedly installed inside the housing, and a second bevel tooth is rotatably installed on the fixed rod. A long tube is fixedly connected to the top of the second bevel tooth, a fixed circular plate is fixedly connected to the top of the long tube, and a fixed long plate is fixedly installed on the long tube. An electric push rod is fixedly installed on the fixed long plate.

[0008] As a preferred embodiment of the above technical solution, the drive assembly includes a mounting bracket fixedly installed inside the housing, and a motor is fixedly installed at the middle end of the mounting bracket. A first bevel gear is fixedly installed on the output shaft of the motor, and the first bevel gear meshes with a second bevel gear.

[0009] As a preferred embodiment of the above technical solution, a limiting tube is fixedly installed on the fixed circular plate, and a linkage rod is slidably installed on the inner wall of the limiting tube.

[0010] As a preferred embodiment of the above technical solution, the outer surface of the connecting plate is provided with multiple sets of circular grooves, and the bottom end of the grinding disc is provided with multiple sets of screw holes. The multiple sets of circular grooves and the multiple sets of screw holes are in the same position, and bolts are rotatably installed in the multiple sets of circular grooves and the multiple sets of screw holes.

[0011] As a preferred embodiment of the above technical solution, grooves are provided on both sides of the grinding disc.

[0012] As a preferred embodiment of the above technical solution, a switch is provided on the outer surface of the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention controls the operation of an electric push rod via an operating switch. The electric push rod drives the linkage rod to move up and down within the limiting tube. Since the linkage rod is hinged to the connecting plate, it pushes or pulls the connecting plate to rotate around the hinge point between the connecting plate and the connecting plate, thereby adjusting the tilt angle of the connecting plate. This, in turn, causes the grinding disc to tilt synchronously, allowing the grinding disc to better fit the surface of ceramic blanks of different shapes, achieving precise and efficient grinding, and greatly improving the versatility and adaptability of the device.

Detailed Implementation

[0023] 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.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a daily-use ceramic blank grinding device, including a housing 1, a bearing 3 is provided on the housing 1, and a positioning ring 4 is rotatably installed on the inner wall of the bearing 3, allowing the positioning ring 4 to rotate. A fixed circular plate 54 is fixedly installed on the inner wall of the positioning ring 4, and a connecting plate 9 is fixedly installed at the top of the fixed circular plate 54. A fixed plate 91 is hinged to the end of the connecting plate 9. A connecting plate 5 is fixedly installed on the inner wall of the fixed plate 91, and a grinding disc 51 is provided on the inner wall of the connecting plate 5. A linkage mechanism 7 is provided on the fixed circular plate 54, and the linkage mechanism 7 includes an electric push rod 74. A linkage rod 75 is fixedly connected to the electric push rod 74, and the connecting plate 5 is hinged to the linkage rod 75. A driving assembly 6 is provided inside the housing 1 for driving the linkage mechanism 7 to rotate.

[0025] As one implementation method in this embodiment, such as Figure 4 and Figure 5As shown, the linkage mechanism 7 also includes a fixed rod 76 fixedly installed inside the housing 1, and a second bevel tooth 71 is rotatably mounted on the fixed rod 76. A long tube 72 is fixedly connected to the top of the second bevel tooth 71, and a fixed circular plate 54 is fixedly connected to the top of the long tube 72. A fixed long plate 73 is fixedly installed on the long tube 72, and an electric push rod 74 is fixedly installed on the fixed long plate 73. The fixed rod 76 provides a stable mounting position for the second bevel tooth 71. They are mounted using bearings, which allows the second bevel tooth 71 to rotate stably on the fixed rod 76, ensuring the transmission stability of the entire linkage mechanism 7. The long tube 72 acts as a bridge connecting the second bevel tooth 71 and the fixed circular plate 54, transmitting the rotational motion of the second bevel tooth 71 to the fixed circular plate 54. At the same time, the fixed long plate 73 is fixedly installed on the long tube 72, providing a mounting base for the electric push rod 74.

[0026] As one implementation method in this embodiment, such as Figure 4 and Figure 5 As shown, the drive assembly 6 includes a mounting bracket 61 fixedly installed inside the housing 1, and a motor 62 is fixedly installed at the middle end of the mounting bracket 61. A first bevel gear 63 is fixedly installed on the output shaft of the motor 62, and the first bevel gear 63 meshes with the second bevel gear 71. The motor 62 serves as a power source, and its output shaft drives the first bevel gear 63 to rotate. Through the meshing transmission between the first bevel gear 63 and the second bevel gear 71, the rotational power of the motor 62 is transmitted to the linkage mechanism 7 to realize the rotation of the grinding disc 51.

[0027] As one implementation method in this embodiment, such as Figure 6 As shown, a limiting tube 8 is fixedly installed on the fixed circular plate 54, and a linkage rod 75 is slidably installed inside the limiting tube 8. The limiting tube 8 plays a precise guiding and limiting role for the linkage rod 75, ensuring that the linkage rod 75 can only move up and down along the axial direction of the limiting tube 8, preventing the linkage rod 75 from deviating or shaking during the movement, thereby ensuring the accuracy and stability of the electric push rod 74 in adjusting the tilt angle of the connecting plate 5, so that the grinding disc 51 can tilt at a predetermined angle, improving the precision and effect of grinding.

[0028] As one implementation method in this embodiment, such as Figure 4 and Figure 6As shown, the connecting plate 5 has multiple sets of circular grooves 53, and the bottom of the grinding disc 51 has multiple sets of screw holes 55. The multiple sets of circular grooves 53 and screw holes 55 are in the same position, and bolts 57 are rotatably installed in the multiple sets of circular grooves 53 and screw holes 55. The grinding disc 51 is connected to the connecting plate 5 by bolts 57. This connection method is simple and reliable, and can ensure that the grinding disc 51 will not loosen or fall off during rotation and tilting, thus ensuring the safety and stability of the grinding operation. When the grinding disc 51 is worn and needs to be replaced, the old grinding disc 51 can be easily removed by simply unscrewing the bolts 57, and then a new grinding disc 51 can be installed, which greatly shortens the equipment maintenance time and improves production efficiency.

[0029] As one implementation method in this embodiment, such as Figure 6 As shown, grooves 52 are provided on both sides of the grinding disc 51, which facilitates the operator to replace the grinding disc 51.

[0030] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, a switch 2 is provided on the outer surface of the housing 1. The switch 2 serves as the interface between the operator and the grinding device, allowing the operator to control the start and stop of the grinding device and adjust the rotation and tilt angle of the grinding disc 51.

[0031] Working principle: When it is necessary to polish the daily ceramic blank, the operator starts the entire polishing device by operating the switch 2 set on the housing 1. At this time, the motor 62 in the drive assembly 6 starts to work. The output shaft of the motor 62 drives the first bevel gear 63 to rotate. Since the first bevel gear 63 meshes with the second bevel gear 71 in the linkage mechanism 7, the rotation of the first bevel gear 63 will drive the second bevel gear 71 to rotate synchronously.

[0032] The second bevel tooth 71 is fixedly connected to the long tube 72. Therefore, the rotation of the second bevel tooth 71 will drive the long tube 72 to rotate together. The top end of the long tube 72 is fixedly connected to the fixed circular plate 54, and the long tube 72 is fixedly installed with the fixed long plate 73. Therefore, during the rotation of the long tube 72, the fixed circular plate 54 and the fixed long plate 73 will rotate synchronously.

[0033] The fixed circular plate 54 is fixedly installed inside the positioning ring 4, and the positioning ring 4 is rotatably installed on the housing 1 through the bearing 3. This allows the fixed circular plate 54 to rotate stably. At the same time, a connecting plate 9 is fixedly installed on the fixed circular plate 54, and a connecting plate 5 is hinged on the connecting plate 9. A grinding disc 51 is provided inside the connecting plate 5. Therefore, when the fixed circular plate 54 rotates, it will drive the connecting plate 9, the connecting plate 5, and the grinding disc 51 to rotate together, thereby realizing the rotational grinding operation of the grinding disc 51 and providing power for the surface grinding of the ceramic blank.

[0034] While the grinding disc 51 is rotating, if it is necessary to adjust the tilt angle of the grinding disc 51 to accommodate ceramic blanks of different shapes, the electric push rod 74 can be controlled by operating switch 2. The electric push rod 74 is fixedly installed on the fixed long plate 73 and rotates synchronously with the rotation of the fixed long plate 73.

[0035] A linkage rod 75 is fixedly connected to the electric push rod 74. The linkage rod 75 is slidably installed in the limiting tube 8 fixedly installed on the fixed circular plate 54. The limiting tube 8 restricts the movement direction of the linkage rod 75, ensuring that the linkage rod 75 can only move in the up and down direction. When the electric push rod 74 is working, its telescopic rod will drive the linkage rod 75 to move up and down in the limiting tube 8.

[0036] Since the connecting plate 5 is hinged to the linkage rod 75, when the linkage rod 75 moves up and down, it will push or pull the connecting plate 5 to rotate around the hinge point between it and the connecting plate 9, so that the tilt angle of the connecting plate 5 can be adjusted up and down. The grinding disc 51 is set inside the connecting plate 5, so the change in the tilt angle of the connecting plate 5 will drive the grinding disc 51 to tilt synchronously, thereby realizing the tilt grinding operation of the grinding disc 51, which can better fit the surface of the ceramic blank and improve the grinding quality and efficiency.

[0037] When the grinding disc 51 wears out due to prolonged use and needs to be replaced, the operator can easily remove the grinding disc 51 from the connecting plate 5 through the slots 52 on both sides of the grinding disc 51. Since the connecting plate 5 has multiple sets of circular slots 53 and the bottom of the grinding disc 51 has multiple sets of screw holes 55, and the multiple sets of circular slots 53 and screw holes 55 are in the same position, bolts 57 are rotatably installed in the multiple sets of circular slots 53 and screw holes 55. When replacing, simply unscrew the bolts 57 to remove the old grinding disc 51, then put the new grinding disc 51 into the connecting plate 5, align the circular slots 53 with the screw holes 55, and then tighten the bolts 57 to complete the replacement of the grinding disc 51. The operation is simple and convenient.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
