Multiple annular baffles and multiple circular discharge ports can be alternately changed, cooperating with multiple retractable or expandable barrel-shaped cover plates II, enabling simultaneous loading and unloading at multiple points. Furthermore, the grinding disc II can drive the multiple annular baffles to rotate, dispersing and flattening multiple special ceramic discs. Then, the upper and lower ends of the discs are polished simultaneously by the grinding discs I and II rotating in opposite directions. During this process, the grinding disc II can also rotate on its own axis while following the rotation of the support rod, effectively improving polishing efficiency and uniformity.

Description

Technical Field

[0001] The invention relates to the technical field of polishing, in particular to a polishing device for special ceramic products. Background Art

[0002] Special ceramic products refer to high-performance ceramic products made of special ceramic materials. Due to their excellent physical, chemical and mechanical properties, they are widely used in many high-tech fields. Compared with traditional ceramic materials (such as daily ceramics and building ceramics), special ceramic products have higher strength, heat resistance, corrosion resistance and electrical properties, so they are often used in extreme environments and occasions with special functional requirements. However, special ceramics often have problems such as high surface roughness and many defects during the production process, which will affect their performance and appearance.

[0003] Existing polishing devices usually use a lower grinding wheel and multiple upper grinding wheels to press and polish special ceramic discs. There may be problems with uneven polishing, and during the process, multiple special ceramic discs need to be placed manually in multiple polishing work areas in turn, and manually dispersed and flattened in turn.

Support vertical plates 457 are installed at the upper ends of the front and rear arc plates 455 corresponding to the positions of the rectangular openings 456. The front and rear support vertical plates 457 are respectively slidably connected in the corresponding rectangular openings 456, and the upper end of the rear support vertical plate 457 is fixedly connected to the rectangular slide seat 467. The rotating shaft 469 rotates through the front support vertical plate 457.

[0050] See also Figure 8-Figure 11 The intermittent pressing portion 62 includes two left and right telescopic rods 621 installed through the upper end of the support frame 2, and the telescopic ends of the left and right telescopic rods 621 are fixedly connected to the barrel-shaped cover plate 61. An annular electromagnet 622 is installed on the inner wall of the upper end of the barrel-shaped cover plate 61, and circular magnetic bars 623 are installed on the upper ends of multiple grinding discs 440 corresponding to the circular avoidance openings on the barrel-shaped cover plate 438.

[0051] It should be noted that at this time, the annular mounting plate 1 434 and the annular mounting plate 2 451 are away from each other. When the special ceramic discs are quantitatively conveyed in all the annular baffle plates 535, the annular electromagnet 622 is first controlled to start adsorbing multiple circular magnetic rods 623, so that the multiple circular magnetic rods 623 all move upward and fit tightly with the annular electromagnet 622, and then the left and right two secondary pneumatic push rods 453 are controlled to jointly drive the annular mounting plate 2 451 to move downward, and the annular mounting plate 2 451 will simultaneously drive the support rod 432 and the front and rear two arc plates 455 to move downward. At this time, the front and rear two arc plates 455 jointly drive the barrel cover plate 1 61 to move downward, and the rear support vertical plate 457 will The rectangular slide 467 is driven to slide downward along the rectangular through hole 466, and the front support vertical plate 457 will drive the rotating shaft 469 to slide downward along the waist-shaped slide groove 465, and the front and rear two cams 470 will follow and move downward, and at the same time, the annular mounting plate 1 434 will follow the support rod 432 to move downward, and under the cooperation of multiple connecting rods 436 and multiple telescopic rods 1 441, multiple annular sleeve plates 437 will respectively drive the corresponding barrel-shaped cover plates 2 438 to move downward, until under the downward squeezing action of multiple barrel-shaped cover plates 2 438, a part of the multiple annular baffle plates 535 will all return to the corresponding annular mounting groove 534, and then the transmission gear is controlled again by the servo motor 545 The second gear 546 rotates counterclockwise at an appropriate angle, and is transmitted through the transmission gear second 546 and the outer gear ring 52, driving the outer gear ring 52 to rotate counterclockwise at an appropriate angle. During this period, under the action of the compression spring, the wedge-shaped slide plate 544 will retreat into the corresponding rectangular mounting groove 543 on the outer gear ring 52, until under the transmission action of the inner gear ring 542 and the multiple passive gear rings 439, the multiple barrel-shaped cover plates 438 will rotate one circle. During this period, under the action of the compression spring, the multiple annular baffle plates 535 will all extend upward and make the corresponding multiple wedge-shaped alignment grooves 443 and the multiple wedge-shaped alignment blocks 539 mesh with each other, thereby achieving the effect that the multiple barrel-shaped cover plates 438 will drive the multiple annular baffle plates 535 to rotate At the same time, multiple annular material baffle plates 535 will respectively drive the corresponding material stripping plates 540 to rotate and flatten multiple special ceramic discs that may be accumulated. During this period, the connecting slide 551 will make adaptive sliding compensation along the annular guide groove 550, and then control the left and right two-stage pneumatic push rods 453 to jointly drive the annular mounting plate 2 451 to move upward. At this time, the front and rear arc plates 455 jointly drive the barrel cover plate 1 61 to move upward, so that the multiple wedge-shaped alignment grooves 443 and the multiple wedge-shaped alignment blocks 539 are disengaged. Under the action of the compression spring, the connecting slide 551 will slide along the annular guide groove 550 to return to its original position. At this time, the material stripping plate 540 is located above the rectangular avoidance opening 547.

[0052] Again, the two left and right secondary pneumatic push rods 453 jointly drive the annular mounting plate 2 451 to move downward. At this time, the front and rear two arc plates 455 jointly drive the barrel-shaped cover plate 1 61 to move downward. At the same time, the annular electromagnet 622 is controlled to close and stop adsorbing the multiple circular magnetic rods 623. Under the action of the compression spring, the multiple circular magnetic rods 623 will drive the grinding disc 2 440 to move downward and press on the corresponding multiple special ceramic discs. The two left and right secondary pneumatic push rods 453 are controlled again to jointly drive the annular mounting plate 2 451 to move downward. At this time, the multiple barrel-shaped cover plates 2 438 will drive the corresponding annular material baffle plates 535 to move downward. During this period, the multiple material stripping plates 540 will follow the downward movement and exit into the corresponding rectangular avoidance openings 547. At this time, the lower end surfaces of the multiple barrel-shaped cover plates 2 438 are movably fitted on the inner walls of the corresponding U-shaped guide grooves 531, and the multiple special ceramic discs in the multiple U-shaped guide grooves 531 are respectively located in the corresponding barrel-shaped cover plates 2 438.

[0053] See also Figure 6 , Fig. 9 and Fig.10 The expansion portion 46 includes an annular slide groove 461 provided at the upper end of an annular mounting plate 434, and two left and right support slide bars 462 are slidably installed in the annular slide groove 461 through a limiting slide plate. The upper end of the support frame 2 is connected to a return plate 463 through a plurality of compression springs. The upper ends of the left and right support slide bars 462 are both slidably penetrated on the support frame 2 and fixedly connected to the return plate 463. The upper end of the support frame 2 is symmetrically provided with a mounting vertical plate 464, and a waist-shaped slide groove is provided at the rear end of the front mounting vertical plate 464. 465, a rectangular through hole 466 is provided at the front end of the rear mounting plate 464, a rectangular slide 467 is slidably installed in the rectangular through hole 466, a No. 3 motor 468 is installed on the rectangular slide 467, the output shaft of the No. 3 motor 468 is fixedly connected with a rotating shaft 469, and a front and rear cams 470 are fixedly sleeved on the rotating shaft 469 at the position corresponding to the circular plate 463, and the front end of the rotating shaft 469 is slidably connected in the waist-shaped slide groove 465, and the front and rear cams 470 both roll and contact with the circular plate 463.

[0054] Then, the third motor 468 controls the rotation of the rotating shaft 469, and the rotating shaft 469 drives the front and rear cams 470 to rotate. Under the action of multiple compression springs, the return plate 463 drives the left and right support slide bars 462 to move upward, and the left and right support slide bars 462 jointly drive the annular mounting plate 1 434 to move upward. Under the cooperation of multiple connecting rods 436 and multiple telescopic rods 1 441, the annular mounting plate 1 434 will drive the multiple barrel-shaped cover plates 2 438 to move toward the support rod 432 respectively, until the multiple barrel-shaped cover plates 2 438 are close to each other and become a retracted state. Under the action of the spring, multiple material-blocking slides 549 will be returned to the corresponding installation slots 548 under the squeezing action of the corresponding barrel-shaped cover plates 438. The secondary grinding mechanism 4 can control the multiple barrel-shaped cover plates 438 to retract or expand, as well as to rise and fall freely. The special ceramic discs in the multiple annular material-blocking plates 535 can be dispersed and flattened before being taken out, and transported to the grinding wheel 1 33. The grinding wheel 1 33 and the grinding wheel 2 440 then cooperate to polish the upper and lower ends of the multiple special ceramic discs at the same time, thereby avoiding the problem of low efficiency of the conventional material unloading method that requires manual dispersion and flattening of multiple special ceramic discs.

[0055] When the multiple barrel-shaped cover plates 438 are close to each other and become retracted, the multiple barrel-shaped cover plates 438 will drive the corresponding special ceramic discs to move to the upper end of the grinding disc 33, and the grinding disc 33 is controlled to rotate forward by the No. 1 motor 35. At the same time, the mounting barrel 41 is controlled by the No. 2 motor 435 to drive the support rod 432 to reverse. The support rod 432 drives the multiple connecting rods 436 to reverse around the support rod 432 through the annular mounting plate 434. The multiple connecting rods 436 respectively drive the corresponding barrel-shaped cover plates 438 to reverse around the support rod 432. Under the transmission action of the transmission gear 34 and the multiple passive gear rings 439, the multiple barrel-shaped cover plates 438 will drive the multiple grinding discs 440 to rotate. At the same time, under the action of the compression spring, the multiple circular magnetic bars 623 will follow the barrel-shaped cover. During the period when plate 2 438 reverses around the support rod 432, it intermittently conflicts with the multiple annular electromagnets 622, thereby achieving the effect of driving the corresponding grinding disc 2 440 to move back and forth up and down. It should be noted that during the period when grinding disc 2 440 reciprocates up and down, it always fits against the upper ends of multiple special ceramic discs. The difference is that the pressure on the multiple special ceramic discs will change. At this time, the multiple special ceramic discs will follow the barrel-shaped cover plate 2 438 to reverse around the support rod 432, and the grinding disc 1 33 and the grinding disc 2 440 will polish the multiple special ceramic discs respectively. The multiple special ceramic discs will rotate with the grinding disc 2 440. At the same time, the grinding disc 2 440 will press the multiple special ceramic discs back and forth up and down, effectively improving the polishing effect on the upper and lower ends of the multiple special ceramic discs.

[0056] After the upper and lower ends of the multiple special ceramic discs are polished, the servo motor 545 controls the transmission gear 2 546 to rotate clockwise, and the transmission gear 2 546 and the outer gear ring 52 are transmitted to drive the outer gear ring 52 to rotate clockwise. During this period, under the action of the wedge-shaped slide plate 544, the outer gear ring 52 will drive the annular plate 2 51 to rotate synchronously clockwise by an appropriate angle. At this time, the initial positions of the multiple annular baffle plates 535 and the circular discharge opening 533 are changed, that is, the positions of the multiple barrel-shaped cover plates 2 438 correspond to the positions of the multiple circular discharge openings 533 respectively, and then the rotating shaft 469 is controlled by the third motor 468 to continue to rotate, and the rotating shaft 469 drives the front and rear cams 470 to rotate. Under the action of multiple compression springs, the circular plate 463 drives the left and right support The slide bar 462 moves downward, and the left and right supporting slide bars 462 jointly drive the annular mounting plate 434 to move downward. Under the cooperation of multiple connecting rods 436 and multiple telescopic rods 441, the annular mounting plate 434 will drive the multiple barrel-shaped cover plates 438 to move away from the support rod 432 respectively, until the multiple barrel-shaped cover plates 438 move away from each other and restore the outward expansion state, and are respectively at the upper end of the corresponding circular discharge port 533. At this time, the polished multiple special ceramic discs will be discharged downward from the corresponding circular discharge port 533 into the annular receiving plate 536, and the multiple trapezoidal scraper plates 32 always rotate with the support barrel 31. The multiple trapezoidal scraper plates 32 will intermittently drive the polished multiple special ceramic discs to be discharged from the arc discharge port 537 and received by the external receiving equipment.

[0057] By repeating the above operation, the upper and lower ends of the special ceramic disc can be repeatedly polished. The first-level grinding mechanism 3, the second-level grinding mechanism 4, the loading and unloading mechanism 5 and the intermittent pressing mechanism 6 cooperate with each other. Multiple annular baffle plates 535 and multiple circular discharge ports 533 can be alternately transformed, and cooperate with multiple barrel-shaped cover plates 438 that can be retracted or expanded to realize multi-point loading and unloading at the same time. The grinding disc 440 can drive the multiple annular baffle plates 535 to rotate, and the multiple special ceramic discs are dispersed and flattened. Then, the upper and lower ends are polished simultaneously by the grinding disc 1 33 and the grinding disc 2 440 with opposite rotation directions. During this period, the grinding disc 2 440 can also rotate while following the rotation of the support rod 432, so as to effectively improve the polishing efficiency and polishing uniformity.
