This ceramic production trimming device utilizes a variable-diameter first sprocket and tensioner assembly. The sprocket drive ratio is automatically adjusted based on tool displacement feedback, ensuring the rotary table speed precisely matches the cutting requirements while maintaining a constant motor speed. A torsion spring maintains chain tension, ensuring transmission stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0029] For example 1, please refer to Figures 1-10 A ceramic blank repairing device includes a base 100, a rotating table 200 is rotatably provided on the base 100, and the rotating table 200 is used to place a blank 300.

[0030] The base 100 is further provided with a trimming mechanism 400 , a first transmission mechanism 500 and a driving mechanism 600 . The trimming mechanism 400 includes a first slide 410 and a turning tool 420 . The turning tool 420 is elastically connected to the first slide 410 via a spring damper 430 .

[0031] The driving mechanism 600 includes a rotating base 610 rotatably disposed in the base 100 . A turntable 620 is disposed on the rotating base 610 . The turntable 620 is connected to the rotating platform 200 .

[0032] When the blank 300 rotates with the rotary table 200, the outer surface of the blank 300 is peeled by the turning tool 420. The change in thickness of the outer surface of the blank 300 drives the turning tool 420 to move. When the turning tool 420 moves, the rotation speed of the rotary table 200 is adjusted by the first transmission mechanism 500.

[0033] In this embodiment, when a mechanical device is used to automatically trim a blank 300, the blank 300 is first placed on a rotating table 200 located at the center of the upper end of the base 100, such that the central axis of the blank 300, the central axis of the rotating table 200, and the central axis of the cylindrical portion on the right side of the base 100 coincide. During the trimming process, the blank 300 can be secured by installing a fixing column on the rotating table 200, a pressure beam on the base 100, or an elastic retainer for automatic centering on the base 100. These conventional techniques are not described here.

[0034] After the blank 300 is secured, a first slide 410 is installed on the base 100. The first slide 410 is radially distributed along the left side of the blank 300. The first slide 410 does not directly secure the turning tool 420. Instead, the turning tool 420 is connected to the first slide 410 via a spring damper 430, allowing the turning tool 420 to move to a certain extent. The spring damper 430 is composed of a hydraulic or pneumatic damper and a spring. The left end of the damper contacts the first slide 410, keeping it stationary. The right end of the damper contacts the turning tool 420, allowing it to move. The two ends of the spring are connected to the two ends of the damper, respectively. The damper absorbs some kinetic energy, allowing the turning tool 420 to move slowly both when subjected to force and when resetting.

[0035] When the blank is trimmed, the driving mechanism 600 drives the rotating seat 610 and the rotating disk 620 coaxial with the rotating table 200 to rotate, so that the blank 300 rotates based on its central axis, and the rotation direction is not limited. Figure 10 As shown, the outer surface of the blank 300 is uneven, and the thickness of the protrusions at different positions is different. Figure 10 When the dotted circle portion contacts the blank 300 , the resistance value of the turning tool 420 in contact with the blank 300 is small. Under the support force provided by the spring damper 430 for the turning tool 420 , the turning tool 420 will evenly peel off a section of the blank 300 in the dotted circle portion.

[0036] When turning tool 420 and Figure 10 When the first protrusion contacts the turning tool 420, the resistance to the turning tool 420 increases, pushing the turning tool 420 to the left. Figure 10When the second, more prominent portion of the middle section contacts the larger portion, the resistance experienced by the turning tool 420 increases further, pushing it further to the left. Furthermore, as the turning tool 420 moves leftward, the rotational speed of the blank 300 driven by the turntable 620 automatically decreases, reducing the force of the peeling. As the peeling progresses, each protrusion is gradually smoothed, achieving a higher degree of roundness throughout the entire circle of the blank 300.

[0037] The above automatic displacement process of the turning tool 420 and the automatic speed adjustment process of the turntable 620 correspond to the method used by experienced blank trimmers to perform rough trimming on the thicker part of the blank 300 surface with smaller force and speed first, and then gradually perform fine trimming.

[0038] Example 2: This example is an improvement based on Example 1. For details, please refer to Figure 1-Figure 7 A first slide groove 440 is provided on the base 100, and the first slide seat 410 is slidably installed in the first slide groove 440. A first mounting hole 450 is provided on the first slide seat 410, and a first bolt 460 and a first nut 470 are installed in the first mounting hole 450.

[0039] When the blank 300 rotates along with the rotating platform 200 , the first slide 410 and the turning tool 420 are installed in reverse directions, and the inner surface of the blank 300 is peeled by the turning tool 420 .

[0040] In this embodiment: the traditional mechanical blank trimming device is difficult to trim the inner surface of the blank 300 and still relies on manual operation. In this device, the first chute 440 is distributed along the left and right diameters of the blank 300. Figure 1 As shown in FIG, the position of the turning tool 420 can be adjusted to contact the left outer surface of the blank 300. The blank trimming mechanism 400 can also be adjusted as a whole. Figure 5 After being rotated 180° as shown in FIG, the trimming mechanism 400 is integrally installed inside the blank 300, so that the turning tool 420 contacts the left inner surface of the blank 300, thereby performing rotary trimming on the inner surface of the blank 300. In actual operation, two trimming mechanisms 400 can be installed simultaneously to perform rotary trimming on the inner and outer surfaces of the blank 300 simultaneously.

[0041] By tightening the first nut 470 , the first sliding seat 410 can be fixed at a certain position of the first sliding groove 440 in a pressing manner.

[0042] Example 3: This example is an improvement made on the basis of Example 2. For details, please refer to Figures 1-11The driving mechanism 600 also includes a first sprocket 630 arranged on the turntable 620, a first rotating rod 640 is rotatably arranged on the base 100, a second sprocket 650 is arranged on the first rotating rod 640, and the second sprocket 650 is transmission-connected to the first sprocket 630 through a chain 660. A motor 670 is arranged on the base 100, and the output shaft of the motor 670 is connected to the first rotating rod 640.

[0043] The first sprocket 630 includes a plurality of arc-shaped teeth 631 circumferentially arranged on the rotating disk 620 , and a complete sprocket is formed by the plurality of arc-shaped teeth 631 .

[0044] A plurality of second chutes 632 are provided on the circumference of the turntable 620, and a slider 633 is provided on each of the arc-shaped tooth portions 631. The sliders 633 are respectively slidably connected to the plurality of second chutes 632. When the output speed of the motor 670 is constant, the speed of the turntable 620 is adjusted by adjusting the transmission ratio between the first sprocket 630 and the second sprocket 650.

[0045] The drive mechanism 600 further includes a tensioning assembly 680 , which includes a third sprocket 685 , which is engaged with the second sprocket 650 .

[0046] The base 100 is provided with a mounting seat 681 , a second rotating rod 682 is rotatably provided on the mounting seat 681 , a support plate 683 is provided on the second rotating rod 682 , a third rotating rod 684 is rotatably provided on the support plate 683 , and a third sprocket 685 is provided on the third rotating rod 684 .

[0047] The tensioning assembly 680 further includes a torsion spring 686 , with two ends of the torsion spring 686 connected to the mounting seat 681 and the support plate 683 , respectively.

[0048] In this embodiment, the motor 670 drives the first rotating rod 640 and the second sprocket 650 to rotate, and the second sprocket 650 drives the first sprocket 630, the rotating disk 620, and the rotating base 610 to rotate via the chain 660. The first sprocket 630 is not a complete sprocket with a fixed size, but is a nearly integral sprocket composed of a plurality of arc-shaped teeth 631, and performs the same transmission function as the second sprocket 650.

[0049] The size of the first sprocket 630 is adjustable. By controlling the synchronous sliding of a plurality of arcuate teeth 631 and a slider 633 along a plurality of equally spaced radial second slots 632 of the turntable 620, the first sprocket 630 can be radially expanded or contracted, thereby adjusting the transmission ratio between the first sprocket 630 and the second sprocket 650.

[0050] When the diameter of the first sprocket 630 decreases, the linear velocity of the second sprocket 650 remains unchanged due to the unchanged output of the motor 670, but the angular velocity of the first sprocket 630 increases, thereby increasing the rotational speed of the first sprocket 630. Conversely, when the diameter of the first sprocket 630 increases, the rotational speed of the first sprocket 630 decreases.

[0051] The tensioning assembly 680 uses the elastic force provided by the torsion spring 686 to press the support plate 683 as tightly as possible toward the chain 660. The third sprocket 685 rotates with the transmission of the chain 660, allowing the chain 660 to continue to transmit normally after the diameter of the first sprocket 630 changes.

[0052] Figure 11 The changes from top to bottom in the figure show the states of the first sprocket 630, the second sprocket 650, the chain 660, and the third sprocket 685 before and after the diameter of the first sprocket 630 is reduced. The working principle of changing the sprocket diameter to change the rotational speed is a conventional technical means. For details, please refer to the relevant principles in Publication No. CN114586508B.

[0053] Example 4: This example is an improvement made on the basis of Example 3. For details, please refer to Figures 1-8 A second transmission mechanism 700 is provided in the base 100, and the second transmission mechanism 700 includes a slide rod 710 slidably provided on the rotating seat 610 and the turntable 620, and a first connecting seat 720 is provided on each of the sliders 633, and a plurality of second connecting seats 730 are circumferentially provided on the slide rod 710.

[0054] The second transmission mechanism 700 further includes a plurality of first connecting rods 740 . Both ends of the first connecting rods 740 are provided with first rotating shafts 750 . The two first rotating shafts 750 are rotatably connected to the first connecting seat 720 and the second connecting seat 730 , respectively.

[0055] The first transmission mechanism 500 includes a connecting rod 510 arranged on the sliding rod 710, a lifting seat 520 is slidably arranged in the base 100, the connecting rod 510 is rotatably connected to the lifting seat 520, the lifting seat 520 is elastically connected to the base 100 through a spring 530, and a pressure rod 540 is slidably arranged on the first sliding seat 410, and the pressure rod 540 is connected to the turning tool 420.

[0056] In this embodiment, when the turning tool 420 moves leftward, it drives the pressure rod 540 upward. The further the turning tool 420 moves leftward, the further the pressure rod 540 moves upward. When installed, the pressure rod 540 contacts the lifting seat 520, pressing it downward a certain distance. When the pressure rod 540 moves upward, the lifting seat 520 returns upward under the elastic force of the spring 530. The lifting seat 520 then drives the connecting rod 510, which is rotatably mounted thereon, upward. The connecting rod 510 drives the slide bar 710 upward.

[0057] When the slide rod 710 rises, the second connecting seat 730, the first connecting rod 740 and the first connecting seat 720 drive the plurality of arc-shaped teeth 631 to radially expand synchronously, thereby increasing the diameter of the first sprocket 630 and reducing the rotation speed of the blank 300.

[0058] Taking the connecting rod structure on the left side as an example, the sliding rod 710 rises to drive the second connecting seat 730 to rise, and the first connecting rod 740 rotates counterclockwise based on the first rotating shaft 750 located on the lower side, thereby driving the first connecting seat 720 and the arc-shaped tooth portion 631 to move left.

[0059] Similarly, when the turning tool 420 moves right, the rotation speed of the blank 300 increases.

[0060] Example 5: This example is an improvement made on the basis of Example 4. For details, please refer to Figure 1-Figure 7 The first transmission mechanism 500 also includes a first mounting assembly 550, which includes a second slide 551 and a second connecting rod 552. The second slide 551 is slidably set on the first slide 410, and the second slide 551 is connected to the turning tool 420. A second rotating shaft 553 is provided at both ends of the second connecting rod 552, and the two second rotating shafts 553 are respectively rotatably connected to the second slide 551 and the pressure rod 540.

[0061] The first transmission mechanism 500 also includes a second mounting assembly 560, which includes a third slide 561 slidably set on the second slide 551. The third slide 561 is provided with a second mounting hole 562, and the turning tool 420 is installed in the second mounting hole 562 by a second bolt 563 and a second nut 564.

[0062] A third sliding groove 565 is defined on the second sliding seat 551 , and the third sliding seat 561 is installed in the third sliding groove 565 via a third bolt 566 and a third nut 567 .

[0063] In this embodiment, the mounting position and angle of the turning tool 420 are freely adjustable to accommodate trimming at different heights of the blank 300. After the turning tool 420 is rotated and adjusted within the second mounting hole 562, the angle of the turning tool 420 is fixed by tightening the second nut 564 onto the second bolt 563. The left-right position of the turning tool 420 is controlled by adjusting the position of the first slide 410. The vertical position of the turning tool 420 is secured by sliding the third slide 561 and the spring damper 430 together, and then tightening the third nut 567 onto the third bolt 566.

[0064] When the turning tool 420 moves leftward, it drives the third slide 561, the second slide 551 and the right end of the spring damper 430 to move leftward. The second slide 551 moves leftward through the transmission of the connecting rod structure composed of the second connecting rod 552 and the two second rotating shafts 553 to drive the pressing rod 540 to rise.

[0065] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
