[0002] Ceramic grinding equipment is used to perform surface finishing on ceramic workpieces. Its core function is to remove excess material from the surface of the workpiece, correct dimensional errors, and improve its flatness, smoothness, or precision through the relative movement between the grinding media (such as grinding wheels, grinding heads, and grinding fluid) and the ceramic workpiece. It is widely used in fields such as ceramic valve cores, electronic ceramic components, and ceramic cutting tools.

[0003] Currently, most ceramic grinding devices on the market require multiple steps, such as rough grinding and fine grinding, to achieve high precision. This not only involves complicated processes and the accuracy can be affected by positioning deviations during switching, but also increases processing time and cost, resulting in insufficient surface finish or out-of-tolerance dimensions.

[0024] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 4As shown, this application provides a ceramic grinding device, including: a double-head grinding device, including two sets of grinding wheels 3, a transmission shaft 7 fixedly connected inside the two sets of grinding wheels 3, multiple sets of ceramic workpieces 14 attached to the bottom end of the grinding wheels 3, a feeding turntable 2 movably sleeved on the outer wall of the ceramic workpieces 14, and a gear 3 12 meshing on the side of the feeding turntable 2, for performing multiple grindings on the ceramic workpieces 14 to improve grinding accuracy.

[0028] After adopting the above technical solution, since the feeding turntable 2 is the core component for workpiece conveying, it has multiple pre-set slots for ceramic workpieces 14, which can simultaneously fit multiple sets of ceramic workpieces 14. When the feeding turntable 2 starts to operate, it will drive all the fitted ceramic workpieces 14 to make stable circular motion around the support column 5 as the center, so that the workpieces can pass directly under the two sets of grinding wheels 3 in sequence. When the ceramic workpiece 14 moves to the bottom of the grinding wheel 3, the high-speed rotating grinding wheel 3 will precisely fit the surface of the workpiece for grinding. The two sets of grinding wheels 3 are matched with different grits according to the ceramic processing requirements. Through the continuous operation mode of "preliminary dressing followed by fine grinding", the ceramic workpiece 14 can directly achieve the ideal surface fineness without secondary clamping or process switching. This greatly improves the dimensional accuracy and smoothness after grinding, and significantly reduces the time cost and error risk of multiple process switching in traditional processing. In addition, the two sets of grinding wheels 3 are rigidly linked through the transmission shaft 7 to ensure that their speed and direction are completely synchronized, avoiding the problem of uneven grinding of the workpiece caused by the difference in grinding wheel speed, and ensuring the efficiency and consistency of grinding the bottom ceramic workpiece 14.

[0029] It should be noted that the two sets of grinding wheels 3 should be two grinding wheels with different mesh sizes, and the difference between the mesh sizes should be set at about 2-4 times. If the difference between the mesh sizes is too large, it will cause the surface roughness to change too drastically, increasing the risk of surface defects. If the difference between the mesh sizes is too small, it may increase the number of processing steps and time, and reduce processing efficiency.

[0030] In one optional embodiment, the inner wall of gear 3 12 is fixedly connected to the output end of motor 2 11, and the outer wall of motor 2 11 is fixedly connected to the outer wall of base 1. Stable power is provided by motor 2 11, and its output end directly drives gear 3 12 to rotate smoothly inside base 1. Gear 3 12 meshes with the transmission structure on the side of the feeding turntable 2, thereby driving the feeding turntable 2 to rotate uniformly within the defined area of ​​base 1. This gear transmission method not only transmits power efficiently but also precisely controls the rotational speed of the feeding turntable 2, ensuring that ceramic workpieces 14 can rotate sequentially to the bottom of the grinding wheel 3 at optimal intervals, achieving uninterrupted and efficient grinding operations and avoiding problems such as workpiece accumulation or processing gaps.

[0031] In an optional embodiment, a support frame 6 is movably sleeved on the outer wall of the transmission shaft 7, and a support column 5 is fixedly connected to the bottom end of the support frame 6. The bottom end of the support column 5 is fixedly connected to the base 1. The device adopts a lightweight and high-strength connection structure between the support column 5 and the support frame 6. Under the premise of not interfering with the rotation trajectory of the feeding turntable 2, it provides stable support for the grinding components and transmission components at the top of the device, effectively avoiding grinding deviations caused by structural shaking. At the same time, the two ends of the support frame 6 are sleeved with the transmission shaft 7 to support the transmission shaft 7 and reduce the radial runout of the transmission shaft 7 when it rotates at high speed, further ensuring the stability of the operation of the two sets of grinding wheels 3 and providing a structural foundation for high-precision grinding.

[0032] In one optional embodiment, a feeding turntable 2 is movably sleeved inside the base 1, and the inner wall of the feeding turntable 2 is movably sleeved with the supporting base column 5. The feeding turntable 2 always rotates around the supporting base column 5 as the center. The positioning accuracy of the supporting base column 5 directly determines the concentricity of the feeding turntable 2, which can effectively avoid the offset during the rotation of the turntable and ensure that the workpiece can be accurately aligned with the grinding area of ​​the grinding wheel 3 every time.

[0033] In one optional embodiment, a gear 8 is fixedly connected to the outer wall of the transmission shaft 7, a gear 9 meshes with the bottom end of the gear 8, and the output end of a motor 10 is fixedly sleeved on the inner wall of the gear 9. The outer wall of the motor 10 is fixedly connected to the support frame 6. After starting the motor 10, the output end of the motor 10 drives the gear 9 to rotate at high speed through a coupling. The gear 9 and the gear 8 fixed at the end of the transmission shaft 7 form a tight meshing transmission, which in turn drives the transmission shaft 7 to rotate smoothly within the bearing sleeve of the support frame 6. Since the two sets of grinding wheels 3 are fixed at both ends of the transmission shaft 7, the synchronous rotation of the transmission shaft 7 can directly drive the two sets of grinding wheels 3 to achieve completely synchronous rotation, ensuring that the grinding force and speed of the two sets of grinding wheels on the workpiece are completely consistent, thus ensuring the processing accuracy from the power source level.

[0034] In one optional embodiment, the feed turntable 2 has several sets of slots inside, each slot being two circles of different sizes. A ceramic workpiece 14 is movably fitted onto the inner wall of each slot, with the top of the workpiece 14 extending above the top of the feed turntable 2. The diameter of the ceramic workpiece 14 is smaller than the width of the grinding wheel 3. The inner wall of the base 1 is fixedly fitted with the outer wall of the cylinder 13, and the output end of the cylinder 13 is fitted into one set of slots, with its diameter smaller than the inner diameter of the slot. In the workpiece limiting and unloading process, the device has optimized the irregular structure of the slot on the feeding turntable 2: the slot is designed as two coaxial circles with different diameters. The diameter of the upper circle is precisely matched with the outer diameter of the ceramic workpiece 14. When the ceramic workpiece 14 is fitted into the slot, the upper large circle can form a radial limit on the workpiece in all directions, preventing the workpiece from shifting or shaking during the grinding process. The diameter of the lower circle is slightly smaller than the outer diameter of the workpiece, which does not affect the stable placement of the workpiece and can provide a support base for unloading. After the ceramic workpiece 14 is ground, the cylinder 13 preset inside the base 1 will be activated. Its output end pushes the workpiece upward from the small circle at the bottom of the slot, pushing the workpiece out of the slot from the large circle at the top, realizing rapid unloading without manual removal, and greatly improving unloading efficiency.

[0035] In one optional embodiment, a ramp is provided on one side of the output end of the cylinder 13, and the ramp faces the front. The output end of the cylinder 13 is designed as a smooth ramp. When the workpiece is ejected from the slot, it will slide naturally down the ramp towards the front of the device, which makes it convenient for workers or subsequent conveying mechanisms to collect the polished ceramic workpieces 14 in a concentrated manner, avoiding the accumulation or damage of the workpieces after unloading.

[0036] In one optional embodiment, a guide block 4 is fixedly connected to the top of the base 1. The guide block 4 has an inclined groove inside, and a discharge hole larger than the diameter of the ceramic workpiece 14 is opened at the corresponding position of the groove. In the workpiece loading stage, the device is equipped with the guide block 4 as an automatic loading auxiliary structure: the guide block 4 is designed with an overall inclination, and has a guide channel inside that is adapted to the ceramic workpiece 14. The operator only needs to place the ceramic workpieces 14 to be ground in batches at the feed end of the guide block 4, and the workpieces will automatically slide down to the lower discharge end along the inclined guide channel under their own gravity. The discharge end of the guide block 4 is precisely aligned with the movement trajectory of the slot of the feeding turntable 2, and the discharge end is equipped with a discharge hole. When the discharge hole is aligned with the empty slot on the feeding turntable 2 that has been unloaded, the ceramic workpiece 14 in the guide channel will automatically fall into the slot under the action of gravity, completing the connection with the feeding turntable 2. The gravity-driven automatic feeding structure does not require additional power drive, which simplifies the feeding process and ensures that the workpiece is accurately placed into the slot. With the continuous rotation of the feeding turntable 2, the entire process of "feeding-grinding-unloading" is fully automated, further improving the overall processing efficiency of the device.
