Description

Technical Field

[0001] This invention belongs to the field of ceramic product polishing technology, and more specifically, relates to a fine grinding equipment and fine grinding method for ceramic product production. Background Technology

[0002] Electronic ceramics refer to ceramics that can utilize electrical and magnetic properties in the electronics industry. Electronic ceramics are ceramics with new functions achieved through precise control of their surface, grain boundaries, and dimensional structure, and can be widely used in energy, home appliances, automobiles, and other fields. The smoothness of the electronic ceramic surface is one of the important indicators of product quality; therefore, polishing is necessary during the production process.

[0003] When grinding hollow cylindrical electronic ceramics, it is necessary to grind their outer surface, inner surface, and end face. Currently, existing grinding devices require both a grinding mechanism and a clamping mechanism to grind and hold the hollow cylindrical electronic ceramics, which makes them functionally limited and structurally complex. This increases the maintenance time and cost of both the grinding and clamping mechanisms. Therefore, a fine grinding equipment and method for ceramic product manufacturing is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fine grinding equipment and method for ceramic product manufacturing.

[0006] Preferably, the first clamping mechanism includes a movable sleeve, a mounting plate, a second cylinder, a positioning rod, a limiting block, a push rod, a push ring, a first arc-shaped grinding block, a second arc-shaped grinding block, a first limiting rod, and a second limiting rod. The mounting plate is fixedly installed at the bottom of the lifting frame, the second cylinder is fixedly installed at the top of the mounting plate, the movable sleeve is sleeved on the rotating rod, the movable sleeve is movably installed inside the push ring, the telescopic rod of the second cylinder is fixedly installed on the push ring, the positioning rod is fixedly installed on the push ring, the positioning rod is movably inserted into the mounting plate, and the limiting blocks are evenly distributed along the circumference of the rotating rod.

[0007] Preferably, the push rods are provided in two sets, and the two sets of push rods are symmetrically hinged to the surface of the movable sleeve. The first arc-shaped grinding block is hinged to the end of one set of push rods, and the second arc-shaped grinding block is hinged to the end of the other set of push rods.

[0008] Preferably, the first limiting rod is fixedly installed on the side of the first arc-shaped grinding block, the second limiting rod is fixedly installed on the side of the second arc-shaped grinding block, the first limiting rod is movably inserted into the fixed seat, and the second limiting rod is movably inserted into the first limiting rod.

[0009] Preferably, the second clamping mechanism includes a fixed plate, a first movable plate, a first bidirectional lead screw, a guide rod, a second movable plate, a first movable frame, and a second movable frame. The fixed plate is fixedly connected to the surface of the movable sleeve. The first bidirectional lead screw is movably installed inside the fixed plate. The first movable plate is threaded onto the left-hand thread of the first bidirectional lead screw. The second movable plate is threaded onto the right-hand thread of the first bidirectional lead screw. The first grinding strip is disposed on the inner side of the first movable frame and the second movable frame.

[0010] Preferably, the guide rod is fixedly mounted on the fixed plate, and both the first movable plate and the second movable plate are slidably mounted on the guide rod.

[0011] Preferably, the inner wall of the movable sleeve is provided with multiple sets of limiting grooves corresponding to the limiting blocks, and the limiting blocks are disposed in the limiting grooves.

[0012] Preferably, the third clamping mechanism includes a placement seat, a lead screw seat, a second bidirectional lead screw, a first movable seat, a second movable seat, a grinding disc, and a clamping seat. The lead screw seat is fixedly connected to the placement seat and fixedly installed on the upper end of the connecting rod. The second bidirectional lead screw is movably installed in the lead screw seat. The first movable seat is threaded on the left-hand thread of the second bidirectional lead screw, and the second movable seat is threaded on the right-hand thread of the second bidirectional lead screw.

[0013] Preferably, the clamping seat is fixedly installed at the ends of the first movable seat and the second movable seat, the second grinding strip is disposed on the inner side of the clamping seat, and the grinding disc is fixedly installed on the inner top of the placement seat.

[0014] A fine grinding method for a fine grinding equipment used in ceramic product manufacturing includes the following steps: Step 1: Place the ceramic product to be polished in the placement seat, rotate the second bidirectional lead screw, so that when the second bidirectional lead screw rotates, it can drive the first moving seat and the second moving seat to move closer to each other. When the first moving seat and the second moving seat move closer to each other, the ceramic product can be clamped and fixed by the clamping seat in conjunction with the second polishing strip. Step 2: Activate the first cylinder. The extension rod of the first cylinder pushes the lifting frame, causing the lifting frame to move the first clamping mechanism and the second clamping mechanism downwards. This allows the first clamping mechanism to be inserted into the ceramic product while the second clamping mechanism is fitted onto the outside of the ceramic product. Activating the second cylinder pushes the push ring, causing the push ring to move the moving sleeve downwards. The moving sleeve then pushes the push rod, allowing the push rod to push the first and second arc-shaped grinding blocks, enabling them to contact the inside of the ceramic product. Rotating the first bidirectional lead screw causes the first and second moving plates to move closer together. As the first and second moving plates move closer together, the first and second moving frames move closer together, bringing the first grinding strip into contact with the surface of the ceramic product. Step 3: Start the first drive motor. The output shaft of the first drive motor rotates, causing the rotating rod to rotate. This allows the rotating rod to rotate the first and second arc-shaped grinding blocks. When the rotating rod rotates, it can drive the moving sleeve to rotate through the limiting groove and the limiting block. When the moving sleeve rotates, it can drive the fixed plate to rotate. When the fixed plate rotates, it can drive the first and second moving frames to rotate. The rotation of the first and second moving frames drives the first grinding strip to rotate. The rotation of the first and second arc-shaped grinding blocks can grind the inner wall of the ceramic product. The first grinding strip can grind the surface of the ceramic product. The first cylinder can push or drag the lifting frame to adjust the position of the first, second, and first arc-shaped grinding blocks and the first grinding strip, thereby adjusting the grinding position of the ceramic product. Step 4: After the first arc-shaped grinding block, the second arc-shaped grinding block, and the first grinding strip have polished the ceramic product, the second cylinder is activated and the first bidirectional lead screw is rotated. This allows the first and second arc-shaped grinding blocks to be clamped onto the inner wall of the ceramic product, and the second moving frame and the first grinding strip to be clamped onto the surface of the ceramic product. By loosening the second bidirectional lead screw, the force of the second grinding strip clamping onto the surface of the ceramic product is reduced. The second drive motor is then activated, and the output shaft of the second drive motor rotates, causing the connecting rod to rotate. When the connecting rod rotates, it causes the lead screw seat and the placement seat to rotate, thereby allowing the grinding disc and the second grinding strip to polish the surface and ends of the ceramic product located in the placement seat.

[0015] Technical effects and advantages of the present invention: The fine grinding equipment and method for ceramic product manufacturing provided by the present invention have the following advantages compared with the prior art: This invention, through the design of a first clamping mechanism, a second clamping mechanism, and a third clamping mechanism, integrates the grinding mechanism into the clamping mechanism by setting the first arc-shaped grinding block and the second arc-shaped grinding block on the first clamping mechanism, setting the first grinding strip on the second clamping mechanism, and setting the second grinding strip on the third clamping mechanism. This reduces the complexity of the structure and allows the clamping mechanism to perform both clamping and grinding functions on electronic ceramics. This reduces maintenance time and costs during equipment repair and improves the practicality of the equipment. Attached Figure Description

The second movable plate 24 is threaded onto the right-hand thread of the first bidirectional lead screw 22. The first grinding strip 27 is disposed inside the first movable frame 25 and the second movable frame 26.

[0027] It should be noted that the first moving plate 21, the first bidirectional lead screw 22, the guide rod 23, the second moving plate 24, the first moving frame 25 and the second moving frame 26 cooperate to enable the first polishing strip 27 to contact the outer surface of the ceramic product. This allows the ceramic product to be polished while being clamped on the outer surface of the ceramic product to fix it in place, so that the lower part of the ceramic product can be polished subsequently.

[0028] In an optional embodiment: the guide rod 23 is fixedly mounted on the fixed plate 20, and the first movable plate 21 and the second movable plate 24 are both slidably mounted on the guide rod 23.

[0029] In an optional embodiment: the inner wall of the movable sleeve 7 is provided with multiple sets of limiting grooves 11 corresponding to the limiting block 12, and the limiting block 12 is disposed in the limiting groove 11.

[0030] It should be noted that by cooperating with the limiting block 12 and the limiting groove 11, the rotating rod 6 can drive the moving sleeve 7 to rotate. The rotating sleeve 7 can drive the fixed plate 20 to rotate. The rotating plate 20 can drive the first moving frame 25 and the second moving frame 26 to rotate. The rotation of the first moving frame 25 and the second moving frame 26 can drive the first polishing strip 27 to rotate. The rotation of the first arc-shaped polishing block 16 and the second arc-shaped polishing block 17 can polish the inner wall of the ceramic product. The first polishing strip 27 can polish the surface of the ceramic product.

[0031] In an optional embodiment: the third clamping mechanism includes a placement seat 30, a lead screw seat 31, a second bidirectional lead screw 32, a first movable seat 33, a second movable seat 34, a grinding disc 35, and a clamping seat 36. The lead screw seat 31 is fixedly connected to the placement seat 30 and is fixedly installed on the upper end of the connecting rod 29. The second bidirectional lead screw 32 is movably installed in the lead screw seat 31. The first movable seat 33 is threaded onto the left-hand thread of the second bidirectional lead screw 32, and the second movable seat 34 is threaded onto the right-hand thread of the second bidirectional lead screw 32.

[0032] In an optional embodiment: the clamping seat 36 is fixedly installed at the ends of the first movable seat 33 and the second movable seat 34, the second grinding strip 37 is disposed on the inner side of the clamping seat 36, and the grinding disc 35 is fixedly installed on the inner top of the placement seat 30.

[0033] A fine grinding method for a fine grinding equipment used in ceramic product manufacturing includes the following steps: Step 1: Place the ceramic product to be polished in the placement seat 30, rotate the second bidirectional lead screw 32, so that when the second bidirectional lead screw 32 rotates, it can drive the first moving seat 33 and the second moving seat 34 to move closer to each other. When the first moving seat 33 and the second moving seat 34 move closer to each other, the ceramic product can be clamped and fixed by the clamping seat 36 in conjunction with the second polishing strip 37. Step 2: Activate the first cylinder 3. The telescopic rod of the first cylinder 3 pushes the lifting frame 4, causing the lifting frame 4 to move the first clamping mechanism and the second clamping mechanism downwards. This allows the first clamping mechanism to be inserted into the ceramic product while the second clamping mechanism is fitted onto the outside of the ceramic product. Activate the second cylinder 9, which pushes the push ring 15, causing the push ring 15 to move the moving sleeve 7 downwards. The moving sleeve 7 then pushes the push rod 14, allowing the push rod 14 to push the first arc-shaped grinding block 16 and the second arc-shaped grinding block 17, enabling them to contact the inner side of the ceramic product. Rotate the first bidirectional lead screw 22, which moves the first moving plate 21 and the second moving plate 24 closer together. As the first moving plate 21 and the second moving plate 24 move closer together, the first moving frame 25 and the second moving frame 26 move closer together, causing the first grinding strip 27 to contact the surface of the ceramic product. Step 3: Start the first drive motor 5. The output shaft of the first drive motor 5 rotates, driving the rotating rod 6 to rotate. This allows the rotating rod 6 to drive the first arc-shaped grinding block 16 and the second arc-shaped grinding block 17 to rotate. When the rotating rod 6 rotates, it can drive the moving sleeve 7 to rotate through the limiting groove 11 and the limiting block 12. When the moving sleeve 7 rotates, it can drive the fixed plate 20 to rotate. When the fixed plate 20 rotates, it can drive the first moving frame 25 and the second moving frame 26 to rotate. When the first moving frame 25 and the second moving frame 26 rotate, they can drive the first grinding strip 27 to rotate. The rotation of the first arc-shaped grinding block 16 and the second arc-shaped grinding block 17 can grind the inner wall of the ceramic product. The first grinding strip 27 can grind the surface of the ceramic product. The first cylinder 3 can push or drag the lifting frame 4 to adjust the position of the first arc-shaped grinding block 16, the second arc-shaped grinding block 17 and the first grinding strip 27, thereby adjusting the grinding position of the ceramic product. Step 4: After the first arc-shaped grinding block 16, the second arc-shaped grinding block 17, and the first grinding strip 27 have polished the ceramic product, the second cylinder 9 is activated and the first bidirectional lead screw 22 is rotated. This allows the first arc-shaped grinding block 16 and the second arc-shaped grinding block 17 to be clamped on the inner wall of the ceramic product, and the second moving frame 26 and the first grinding strip 27 to be clamped on the surface of the ceramic product. By loosening the second bidirectional lead screw 32, the force of the second grinding strip 37 clamping on the surface of the ceramic product is reduced. The second drive motor 28 is activated, and the output shaft of the second drive motor 28 rotates, driving the connecting rod 29 to rotate. When the connecting rod 29 rotates, it drives the lead screw seat 31 and the placement seat 30 to rotate. Thus, the grinding disc 35 and the second grinding strip 37 can polish the surface and ends of the ceramic product located in the placement seat 30.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

When the first moving seat (33) and the second moving seat (34) move closer to each other, the ceramic product can be clamped and fixed by the clamping seat (36) in conjunction with the second polishing strip (37). Step 2: Start the first cylinder (3). The telescopic rod of the first cylinder (3) pushes the lifting frame (4), causing the lifting frame (4) to move the first clamping mechanism and the second clamping mechanism downwards. This allows the first clamping mechanism to be inserted into the ceramic product while the second clamping mechanism is fitted onto the outside of the ceramic product. Start the second cylinder (9), which pushes the push ring (15). This push ring (15) moves the moving sleeve (7) downwards. The moving sleeve (7) then pushes the push rod (14), allowing the push rod (14) to polish the first arc. The first arc-shaped grinding block (16) and the second arc-shaped grinding block (17) are pushed together so that the first arc-shaped grinding block (16) and the second arc-shaped grinding block (17) can contact the inner side of the ceramic product. By rotating the first bidirectional lead screw (22), the first bidirectional lead screw (22) can drive the first moving plate (21) and the second moving plate (24) to move closer to each other. After the first moving plate (21) and the second moving plate (24) move closer to each other, the first moving frame (25) and the second moving frame (26) move closer to each other, so that the first grinding strip (27) contacts the surface of the ceramic product. Step 3: Start the first drive motor (5). The output shaft of the first drive motor (5) rotates, causing the rotating rod (6) to rotate, so that the rotating rod (6) can drive the first arc-shaped grinding block (16) and the second arc-shaped grinding block (17) to rotate. When the rotating rod (6) rotates, it can drive the moving sleeve (7) to rotate through the limiting groove (11) and the limiting block (12). When the moving sleeve (7) rotates, it can drive the fixed plate (20) to rotate. When the fixed plate (20) rotates, it can drive the first moving frame (25) and the second moving frame (26) to rotate. The rotation of a movable frame (25) and a second movable frame (26) drives the first polishing strip (27) to rotate. The rotation of the first arc-shaped polishing block (16) and the second arc-shaped polishing block (17) can polish the inner wall of the ceramic product. The first polishing strip (27) can polish the surface of the ceramic product. The lifting frame (4) can be pushed or dragged by the first cylinder (3), thereby adjusting the position of the first arc-shaped polishing block (16), the second arc-shaped polishing block (17) and the first polishing strip (27), so as to adjust the polishing position of the ceramic product. Step 4: After the first arc-shaped grinding block (16), the second arc-shaped grinding block (17) and the first grinding strip (27) have polished the ceramic product, the second cylinder (9) is started and the first bidirectional lead screw (22) is rotated so that the first arc-shaped grinding block (16) and the second arc-shaped grinding block (17) can be clamped on the inner wall of the ceramic product, and the second moving frame (26) and the first grinding strip (27) can be clamped on the surface of the ceramic product. By loosening the second bidirectional lead screw (32), the force of the second grinding strip (37) clamping on the surface of the ceramic product can be reduced. The second drive motor (28) is started. The output shaft of the second drive motor (28) rotates and drives the connecting rod (29) to rotate. When the connecting rod (29) rotates, it can drive the lead screw seat (31) and the placement seat (30) to rotate. Thus, the surface and end of the ceramic product located in the placement seat (30) can be polished by the grinding disc (35) and the second grinding strip (37).
