Description

Technical Field

[0001] The present invention relates to the technical field of floating grinding equipment, in particular to a floating grinding machine and a powder energy-saving grinding method for precision ceramic production. Background Art

[0002] In traditional machining, grinding processes are primarily achieved through rigid contact grinding, such as on surface and cylindrical grinders. The core principle is to remove material through mechanical friction between a grinding wheel or disc and the workpiece. However, this type of equipment exhibits significant flaws when machining ultra-hard materials (such as ceramics, silicon carbide, and diamond), which can easily lead to wear on the machining equipment and, in turn, impure ground material. Floating grinders, as high-precision grinding equipment, can adjust the grinding disc position to compensate for vibration and load variations during machining.

[0003] Precision ceramics (such as aluminum oxide, silicon nitride, lead zirconate titanate, etc.) are the main raw materials for various intelligent detection devices, laser sensors, calibration sensors and other sensors. The grinding particle size of precision ceramics directly affects the accuracy of various sensors produced. The preparation of precision ceramics is highly dependent on the particle size distribution, morphology consistency and crystal purity of the raw material powder. Powder grinding, as a front-end process, consumes about 30%-50% of the overall production cost. The traditional ball milling process uses the impact and shearing action of steel balls or ceramic balls in a rotating cylinder to crush the raw materials, but there are two major bottlenecks: one is the low energy conversion rate, with only 0.1%-2% of the input energy being used for actual crushing work, and the rest being dissipated in the form of heat, vibration and noise; the other is the serious over-grinding phenomenon. When the powder reaches the target particle size, it continues to be impacted, resulting in particle agglomeration and increased lattice defects, affecting the sintering densification process.

[0015] A powder energy-saving grinding method for precision ceramic production, using the above-mentioned floating grinding machine, comprises the following steps:

[0016] Separate the lower grinding disc and the upper grinding disc to the maximum distance through the pressing drive mechanism;

[0017] Place the precision ceramic raw material into the grinding tank, and drive the upper grinding disc into the grinding tank through the pressing drive mechanism;

[0018] Driven by the pressing drive mechanism and the lower drive mechanism respectively, the upper grinding disc and the lower grinding disc rotate in opposite directions;

[0019] The upper grinding disc and the lower grinding disc tend to approach each other during the rotation process, grinding and crushing the material inside the grinding tank.

[0020] Compared with the prior art, the present invention provides a floating grinder and a powder energy-saving grinding method for precision ceramic production, which has the following beneficial effects:

[0021] 1. This floating grinder places the material into the grinding groove opened at the top of the lower grinding disc, and then drives the upper grinding disc to extend into the grinding groove through the pressing drive mechanism. As a result, under the drive of the pressing drive mechanism and the lower drive mechanism respectively, the upper grinding disc and the lower grinding disc rotate in opposite directions. During the rotation process, the upper grinding disc and the lower grinding disc tend to approach each other, thereby providing greater pressure from the upper and lower directions during the grinding process of the material, thereby grinding the material more effectively, and thus obtaining material powder with a higher degree of crushing.

[0022] 2. This floating grinder, during the rotation of the upper grinding disc and the lower grinding disc, the centrifugal force generated by the high-speed rotation offsets the pulling force of the upper limiting spring and the lower limiting spring, thereby making the upper sliding limiting block and the lower sliding limiting block tend to open away from the central axis of the lower connecting disc, and making the upper grinding disc and the lower grinding disc tend to approach each other during the rotation, so that during the grinding process of the material, greater pressure can be provided from the upper and lower directions respectively, thereby grinding the material more effectively, and thus obtaining material powder with a higher degree of crushing.

[0023] 3. This type of floating grinder screens the ground and crushed materials inside the grinding trough through the filtering effect of the screening filter plate, and outputs the materials that meet the screening particle size through the discharge port to the top of the discharge slide. Then, as the discharge lever rotates with the lower grinding disc, the materials that meet the screening particle size that fall onto the discharge slide are collected and output to the discharge trough, which can ensure that the output materials meet the required particle size requirements, thereby ensuring the effectiveness of grinding and ensuring that the output high-particle size materials can be completely output from the discharge trough.

[0024] 4. This energy-saving powder grinding method for precision ceramic production has a tendency to approach each other during the rotation of the upper grinding disc and the lower grinding disc because the upper grinding disc and the lower grinding disc rotate in opposite directions. This can provide greater pressure from both the upper and lower directions during the grinding process of the material, thereby reducing the high torque required for the conventional grinding process, thereby reducing energy input and grinding the material more efficiently.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] As introduced in the background technology, in order to solve the deficiencies in the existing technology, this application proposes a floating grinder and a powder energy-saving grinding method for precision ceramic production.

[0040] During use, the upper grinding disc 41 of the upper grinding mechanism 4 is first driven by the pressing drive mechanism 3 to move to the position farthest from the top of the lower grinding disc 21, and then the material to be ground is placed in the grinding groove 211 opened at the top of the lower grinding disc 21, and then the upper grinding disc 41 is driven by the pressing drive mechanism 3 to extend into the grinding groove 211, so that under the respective drive of the pressing drive mechanism 3 and the lower drive mechanism 5, the upper grinding disc 41 and the lower grinding disc 21 rotate in opposite directions, and tend to approach each other during the rotation of the upper grinding disc 41 and the lower grinding disc 21, so that during the grinding process of the material, greater pressure can be provided from the upper and lower directions respectively, and the material can be ground more effectively, so that material powder with a higher degree of crushing can be obtained.

[0045] The upper connecting guide column 43 is provided with a plurality of upper limiting grooves 431 on the outside, and an upper sliding limiting block 44 is provided inside each upper limiting groove 431; the bottom end of the upper sliding limiting block 44 is rotatably connected to the inside of the upper limiting groove 431, and the top end of the upper sliding limiting block 44 is elastically connected to the inner wall of the upper limiting groove 431 near the inside of the upper limiting groove 431 through an upper limiting spring 441; when the upper connecting disk 42 drives the upper grinding disk 41 to rotate at a low speed through the upper connecting guide column 43, each upper sliding limiting block 44 is limited to the inside of each upper limiting groove 431 by the tension of the corresponding upper limiting spring 441; when the upper connecting disk 42 drives the upper grinding disk 41 to rotate at a high speed through the upper connecting guide column 43, each upper sliding limiting block 44 can protrude from the inside of the corresponding upper limiting groove 431, driving the upper grinding disk 41 to move toward the side close to the lower grinding disk 21.

[0047] During the rotation of the upper grinding disc 41 and the lower grinding disc 21, the centrifugal force generated by the high-speed rotation (the dividing point between the low-speed rotation and the high-speed rotation during the rotation of the upper grinding disc 41 and the lower grinding disc 21 is the rotation speed of the upper grinding disc 41 and the lower grinding disc 21 when the upper sliding limit block 44 and the lower sliding limit block 24 just escape from the upper limit groove 431 and the lower limit groove 231) offsets the pulling force of the upper limit spring 441 and the lower limit spring 241, thereby making the upper sliding limit block 44 and the lower sliding limit block 24 have a tendency to open away from the central axis of the lower connecting disc 22, thereby making the upper grinding disc 41 and the lower grinding disc 21 tend to approach each other during the rotation, so that during the grinding of the material, greater pressure can be provided from the upper and lower directions respectively, thereby making the material more effectively ground, thereby obtaining material powder with a higher degree of crushing.

[0048] Example 3:

[0049] See also Figures 1-10The difference from the above embodiment is that the pressing drive mechanism 3 also includes a lifting guide rail 32 and a lifting drive motor 33, and one side of the pressing mounting plate 31 fits with the lifting guide rail 32; a driving mounting platform 34 is provided at the top of the pressing mounting plate 31, and an upper grinding motor 35 is provided at the top of the driving mounting platform 34, and the driving shaft of the upper grinding motor 35 is coaxially fixed with the upper grinding disc 41; the lifting drive motor 33 can drive the pressing mounting plate 31 to rise and fall along the limit of the lifting guide rail 32, and the upper grinding motor 35 can drive the upper grinding disc 41 to rotate.

The lower driving motor 52 is fixed to the lower mounting platform 51. The driving shaft of the lower driving motor 52 is coaxially fixed to the lower grinding disc 21. The lower driving motor 52 can drive the lower grinding disc 21 to rotate.

[0051] When in use, the lifting drive motor 33 can drive the pressing mounting plate 31 to rise and fall along the limit of the lifting guide rail 32, and the upper grinding motor 35 can drive the upper grinding disc 41 to rotate, and the lower drive motor 52 can drive the lower grinding disc 21 to rotate, and then can drive the upper grinding disc 41 and the lower grinding disc 21 to rotate in opposite directions, thereby providing a higher friction pressure on the material inside the grinding groove 211, so as to effectively ensure the grinding particle size and grinding accuracy of the material.

[0052] Example 4:

[0053] See also Figures 1-10 The difference from the above embodiment is that an isolation guardrail 6 is provided at the top of the fixed base 1 and located outside the lower grinding mechanism 2, and a discharge slide 11 is provided at the top of the fixed base 1 and located between the isolation guardrail 6 and the pressing drive mechanism 3, and the side of the discharge slide 11 close to the isolation guardrail 6 is lower than the side of the discharge slide 11 close to the pressing drive mechanism 3; a plurality of discharge ports 212 are provided at the top of the lower grinding disc 21 and located outside the grinding groove 211, and each discharge port 212 is inclined downward at the end away from the grinding groove 211.

[0055] In actual use, the discharge lever 61 is a retractable structure, using a retractable spring rod structure. The discharge lever 61 is retractable to adapt to the change in the distance between the end of the discharge lever 61 close to the lower grinding disc 21 and the inner wall of the isolation guardrail 6, and is retracted and adjusted;

[0056] Therefore, when in use, the material after grinding and crushing inside the grinding trough 211 is screened through the filtering effect of the screening filter plate 213, and the material that meets the screening particle size is output to the top of the discharge slide 11 through the discharge port 212.

[0057] Embodiment 5:

[0058] A powder energy-saving grinding method for precision ceramic production, using a floating grinder as described in any one of Examples 1 to 4, comprises the following steps:

[0062] The upper grinding disc 41 and the lower grinding disc 21 tend to approach each other during the rotation process, grinding and crushing the material inside the grinding groove 211.

[0063] Therefore, during use, since the upper grinding disc 41 and the lower grinding disc 21 rotate in opposite directions, they tend to approach each other during rotation, thereby being able to provide greater pressure from both the upper and lower directions during the grinding process of the material, thereby reducing the large torque required for the conventional grinding process, thereby reducing energy input while being able to grind the material more efficiently, thereby being able to obtain material powder with a higher degree of crushing.
