[0034] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0035] like Figures 1 to 11 The blank repairing machine with adjustable turning thickness shown in the figure comprises a processing table 1, and four mounting blocks 2 (such as Figure 7 As shown), the mounting blocks 2 are all rotatably connected with the rotating shaft 3, the tops of the rotating shafts 3 are all fixedly connected with the placement discs 4, the mounting blocks 2 are connected with the driving revolution mechanism, and the tops of the four placement discs 4 are sequentially connected with the centering fixing mechanism, the adjusting turning mechanism, the pushing unloading mechanism and the disc surface cleaning mechanism;

[0036] A matching self-rotating mechanism is connected to the processing table 1, which drives the placement disc 4 at the center fixing mechanism and the adjusting turning mechanism to rotate along the rotating connection of the rotating shaft 3; during operation, when the prior art is trimming the ceramic blank, the free movement of the turning tool is usually used to adjust the trimming thickness. Before trimming, the ceramic blank needs to be fixed at the axis center of the top of the rotating seat. Traditional blank fixing usually requires manual placement of the blank on the top of the rotating seat and adjustment to the center, and then fixing the blank on the top of the rotating seat. After the trimming is completed, manual unloading is also required, which increases labor costs and reduces the trimming efficiency. Moreover, it is easy to reduce the centering accuracy of the blank through manual adjustment, causing the blank to deviate from the rotation center, thereby reducing the blank repairing effect; the technical solution can solve the above problems, and the specific working method is as follows: the shade-dried ceramic blank is placed on the top of the corresponding placement disk 4, and the ceramic blank is fixed at the center of the top of the placement disk 4 through the action of the centering fixing mechanism, and then the mounting block 2 is driven by the action of the revolution mechanism to drive the corresponding placement disk 4 to perform periodic intermittent rotation, so that the corresponding placement disk 4 drives the centrally positioned ceramic blank to rotate ninety degrees, and then the ceramic blank on the top of the placement disk 4 is adjusted by the action of the turning mechanism. The blank is turned and trimmed. In the process of centering and fixing the ceramic blank and turning and trimming the blank, the centering fixing mechanism and the placing disc 4 at the adjusting turning mechanism are rotated along the rotating connection of the rotating shaft 3 by cooperating with the self-rotating mechanism, and the ceramic blank is driven to rotate synchronously, so that the ceramic blank is fixed and trimmed during the rotation process. After the trimming is completed, the placing disc 4 is continued to be rotated ninety degrees by driving the revolution mechanism, and the trimmed ceramic blank is rotated to the next position, and the trimmed ceramic blank is unloaded by pushing the unloading mechanism, and then the placing disc is driven by driving the revolution mechanism. The disk 4 continues to rotate ninety degrees, and the surface of the placement disk 4 after unloading is cleaned by the disk cleaning mechanism, thereby reducing the influence of dust generated by the placement disk 4 during the processing on the subsequent processing. Through the revolution of the placement disk 4 and the rotation at the corresponding position, the ceramic blank can be automatically centered, trimmed and unloaded, which improves the degree of automation of blank processing while reducing manual operation, reduces the fixed deviation caused by manual adjustment of the center, and improves the trimming effect. Through the intermittent movement of the four placement disks 4, the four placement disks 4 can synchronously perform the processing steps of the corresponding positions, thereby effectively improving the trimming efficiency.

Figure 2As shown), a matching glue spraying mechanism is connected to the glue spraying tube 17, and an elastic pressing mechanism is connected above the multiple extrusion pins 10, and the number of sliding frames 5 is at least three; when working, the multiple sliding frames 5 are arranged at the loading position of the ceramic blank along the circumferential direction, and the ceramic blank is placed on the top of the placement disc 4 between the multiple extrusion pins 10, and then the piston shafts of the multiple first hydraulic cylinders 7 move synchronously, driving the slider 6 to move at the sliding connection inside the sliding frame 5, so that the multiple extrusion pins 10 are close to each other, and the first contact ball 12 at one end of the extrusion pin 10 contacts the side of the ceramic blank. As the piston shaft of the first hydraulic cylinder 7 continues to move, the other end of the extrusion pin 10 moves toward the inside of the corresponding rectangular frame 9 to make way, and the movable plate 13 connected to the extrusion pin 10 moves along the sliding insertion of the light rod 14, and squeezes the first spring 15 to produce compression deformation. The movable plate 13 contacts the corresponding first pressure sensor 16 during the movement. When the pressure value detected by the first pressure sensor 16 reaches the set value, the control connected to the first pressure sensor 16 The controller controls the piston shaft of the first hydraulic cylinder 7 to stop moving, so that multiple extrusion pins 10 generate the same elastic pressure on the side of the ceramic blank, and the first contact ball 12 at one end of the extrusion pin 10 approaches the ceramic blank synchronously, so that the ceramic blank is elastically limited at the center position of the top of the placement disk 4, and then the top of the ceramic blank is elastically pressed by the elastic pressing mechanism, and the corresponding placement disk 4 is rotated unidirectionally by cooperating with the self-rotation mechanism, and the ceramic blank is synchronously rotated with the placement disk 4 by the elastic pressing mechanism. During the rotation of the ceramic blank, the first contact ball 12 at one end of the extrusion pin 10 rolls in the corresponding first spherical groove 11 through contact friction, thereby reducing contact wear and resistance generated by the rotation of the ceramic blank. When the ceramic blank rotates with the placement disk 4, the epoxy resin glue inside the glue spraying tube 17 is sprayed along the connecting nozzle 18 on the contact position between the ceramic blank and the placement disk 4, thereby fixing the ceramic blank at the center of the top of the placement disk 4, and completing the centering of the ceramic blank on the top of the placement disk 4.

When working, the epoxy resin glue pipeline with hydraulic pressure is fixedly connected to the top of the glue spraying tube 17, and the internal channel of the glue spraying tube 17 is blocked by the sliding insertion of the circular pin 20 and the glue spraying tube 17. When the extrusion pin 1 When the movable plate 13 connected to the upper and lower parts of the polished rod 14 moves along the sliding connection of the light rod 14, the movable plate 13 drives the circular pin 20 to move synchronously along the sliding connection of the connecting ring 19, and one end of the circular pin 20 moves along the sliding connection of the glue spraying tube 17. When the movable plate 13 contacts the corresponding first pressure sensor 16, the connecting hole 21 on the circular pin 20 moves to the inside of the glue spraying tube 17 and is connected. The epoxy resin glue moves along the connecting hole 21 and is sprayed along the connecting nozzle 18.

When working, the gear 55 is driven to rotate by the rotation of the output shaft of the first motor 54, and the fixing ring 52 drives the mounting blocks 2 to rotate synchronously along the sliding connection of the first annular track 51 through the meshing action of the gear 55 and the outer gear ring 53, and the placement disc 4 is synchronously moved through the rotation connection between the mounting block 2 and the rotating shaft 3.

[0045] As a further embodiment of the present invention, the self-rotating mechanism includes a second annular track 56, which is fixedly connected to the top of the processing table 1 and is coaxially arranged with the first annular track 51. The bottom of the rotating shaft 3 is fixedly connected to a sliding circular plate 57, and the sliding circular plate 57 is slidably connected to the second annular track 56. The second annular track 56 is provided with two rotating grooves 58 (such as Fig.10As shown in the figure, the interior of the rotating groove 58 is rotatably connected with a matching track 59, the rotating groove 58 and the corresponding sliding circular plate 57 are coaxially arranged, and two second motors 60 are fixedly installed at the bottom of the processing table 1. The output shaft of the second motor 60 passes through the processing table 1 and extends to the top of the processing table 1 and is fixedly connected to the bottom of the corresponding matching track 59; when working, the rotation of the rotating shaft 3 on the mounting block 2 is limited by the sliding connection of the sliding circular plate 57 and the limiting of the second annular track 56. When the ceramic blank is fixed in the center and turned and repaired, the sliding circular plate 57 below the ceramic blank moves along the second annular track 56. The track 56 moves to the corresponding matching track 59 and is limited by the matching track 59. The matching track 59 is then driven to rotate by the output shaft of the second motor 60. The sliding circular plate 57 is limited by the sliding of the matching track 59, so that the sliding circular plate 57 rotates synchronously and drives the corresponding rotating shaft 3 to rotate, thereby rotating the placement disc 4. After rotating a certain number of circles, the output shaft of the second motor 60 drives the matching track 59 to return to the initial position, so that the sliding circular plate 57 can return to the second annular track 56 along the intersection of the matching track 59 and the second annular track 56.

[0046] Working principle of the present invention:

[0047] The shade-dried ceramic blank is placed on the top of the corresponding placement disk 4, and the ceramic blank is fixed at the center of the top of the placement disk 4 by the action of the centering fixing mechanism, and then the mounting block 2 drives the corresponding placement disk 4 to perform periodic intermittent rotation by driving the revolution mechanism, so that the corresponding placement disk 4 drives the centrally positioned ceramic blank to rotate ninety degrees, and then the ceramic blank on the top of the placement disk 4 is turned and trimmed by adjusting the turning mechanism. In the process of centering and fixing the ceramic blank and turning and trimming the ceramic blank, the centering fixing mechanism and the placement disk 4 at the adjusting turning mechanism are rotated along the rotating connection of the rotating shaft 3 by cooperating with the rotation mechanism, and drive the ceramic blank to rotate synchronously, so that the ceramic blank is fixed and trimmed during the rotation process, and the revolution mechanism is continued to be driven after the trimming is completed. The placing disc 4 is rotated 90 degrees, and the trimmed ceramic blank is rotated to the next position, the trimmed ceramic blank is unloaded by pushing the unloading mechanism, and then the placing disc 4 is driven to continue to rotate 90 degrees, and the surface of the placing disc 4 after unloading is cleaned by the disc cleaning mechanism, so as to reduce the influence of dust generated by the placing disc 4 during the processing on the subsequent processing, and the ceramic blank can be automatically centered, trimmed and unloaded through the revolution of the placing disc 4 and the rotation at the corresponding position, which improves the automation degree of blank processing while reducing manual operation, reduces the fixed deviation caused by manual adjustment of the center, improves the repairing effect, and enables the four placing discs 4 to synchronously perform the processing steps of the corresponding positions through the intermittent movement of the four placing discs 4, thereby effectively improving the repairing efficiency.
