Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a drainage hole punching structure for a ceramic blank, including a frame 1, a mold 2 provided on the frame 1, and a plurality of punching mechanisms 3. The mold 2 is provided with a plurality of guiding holes 21 corresponding to the positions of the drainage holes of the ceramic blank. Each punching mechanism 3 includes a bracket 4 provided on the frame 1, a lifting assembly 5 provided on the bracket 4, a rotating assembly 6 provided at the output end of the lifting assembly 5, and a drill bit 7 provided on the rotating assembly 6. One drill bit 7 is correspondingly sleeved in one guiding hole 21.

[0023] In actual use, the ceramic blank is moved below the mold 2, and the position where the drainage hole of the ceramic blank needs to be processed corresponds to the position of the guiding hole 21. Then, each punching mechanism 3 moves synchronously. The rotating assembly 6 drives the drill bit 7 to rotate, and the lifting assembly 5 drives the rotating assembly 6 to move downward, so that the rotating drill bit 7 moves downward along the guiding hole 21 to complete the processing of the drainage hole, realizing the automatic processing of the drainage hole of the ceramic blank with high working efficiency.

[0024] In a preferred embodiment, refer to Figure 2 , the frame 1 includes an upper plate 11, a lower plate 12, and a plurality of upright columns 13 for connecting the upper plate 11 and the lower plate 12. The upper plate 11 is provided with a plurality of positioning holes 14 corresponding to the number of punching mechanisms 3. The bracket 4 is connected to the positioning holes 14, and the mold 2 is provided on the lower plate 12. One positioning hole 14 corresponds to the installation of one punching mechanism 3, so that each punching mechanism 3 is independently arranged, facilitating the adjustment of the drill bit 7 on each punching mechanism 3 to be sleeved in the guiding hole 21.

[0025] Optionally, a through hole 15 is provided on the upper plate 11. The through hole 15 is located within the area enclosed by the plurality of positioning holes 14. The through hole 15 is provided to facilitate the adjustment of the installation position of the drilling mechanism 3.

[0026] In a preferred embodiment, referring to Figure 3 , 4 , the bracket 4 includes a first mounting seat 41, a connecting rod 42, and a second mounting seat 43. The upper end of the first mounting seat 41 is connected to the frame 1. The two ends of the connecting rod 42 are respectively connected to the lower end of the first mounting seat 41 and the upper end of the second mounting seat 43. The lifting assembly 5 is arranged on the second mounting seat 43. By adjusting the mounting angle of the connecting rod 42, the mounting position of the second mounting seat 43 is adjusted, so that the drill bit 7 is sleeved in the guiding hole 21.

[0027] Preferably, referring to Figure 4 , a waist-shaped hole 44 extending in the horizontal direction is provided at the top of the first mounting seat 41. The waist-shaped hole 44 is connected to the positioning hole 14 by screws. Adjusting the position of the screws on the waist-shaped hole 44 can adjust the position of the first mounting seat 41, further improving the flexibility of adjusting the position of the drilling mechanism 3 and avoiding position interference between adjacent drilling mechanisms 3.

[0028] It should be understood that since the drainage holes on the ceramic blank are not all vertical holes, that is, the drainage holes can be inclined holes, and the corresponding guiding holes 21 are also inclined holes. By providing the connecting rod 42 to connect the first mounting seat 41 and the second mounting seat 43, the inclination angle of the second mounting seat 43 can be flexibly adjusted, so that the drill bit 7 slides along the axis of the guiding hole 21.

[0029] In a preferred embodiment, referring to Figure 3 , 4 , the lifting assembly 5 includes a lifting cylinder 51 arranged on the bracket 4 and a sliding seat 52 slidably arranged on the bracket 4 in the vertical direction. The extending rod of the lifting cylinder 51 drives the sliding seat 52 to move. The rotating assembly 6 is arranged on the sliding seat 52. The lifting cylinder 51 is a micro cylinder. The extending or retracting of the extending rod of the lifting cylinder 51 drives the sliding seat 52 to move up and down, so that the drill bit 7 completes the drilling work.

[0030] Specifically, referring to Figure 4 , a guide rail 53 extending along its length direction is provided on the second mounting seat 43. A slider 54 is provided on the sliding seat 52. The guide rail 53 is slidably connected to the slider 54. A positioning block 55 is provided at the bottom of the guide rail 53. A sensor 8 for detecting the position of the slider 54 is installed on the positioning block 55. By adjusting the installation position of the sensor 8, the moving distance of the sliding seat 52 is controlled, and then the drilling depth of the drill bit 7 is controlled to meet the processing requirements of the drainage holes in the ceramic blank.

[0031] In a preferred embodiment, referring toFigure 4 The rotating assembly 6 includes a rotating motor 61 disposed on the slide 52, a driving gear 62 disposed at the output end of the rotating motor 61, and a driven gear 63 meshed with the driving gear 62. The drill bit 7 is rotatably connected to the slide 52, and the driven gear 63 is disposed on the drill bit 7. The rotating motor 61 is a DC motor, and the rotating motor 61 drives the driving gear 62 to rotate, and the driving gear 62 meshes with the driven gear 63, so that the drill bit 7 rotates.

[0032] Further, see Figure 5 A first vent hole 71 is formed on the axis of the drill bit 7. The upper end of the first vent hole 71 is externally connected to an air supply device, and the lower end of the first vent hole 71 extends to the bottom of the drill bit 7. The air supply device delivers compressed gas to the first vent hole 71 through an air pipe. During the drilling process, the compressed gas is output from the bottom of the drill bit 7 to clean the debris in the drainage hole to prevent the debris from staying in the drainage hole, resulting in the debris blocking the drainage hole after the ceramic body is produced.

[0033] For further information, see Figure 4 , 5 In order to ensure the high installation stability of the drill bit 7, it also includes a bearing seat 64 arranged on the slide seat 52, and a connecting rod 65 rotatably connected to the bearing seat 64. The driven gear 63 and the drill bit 7 are both arranged on the connecting rod 65. The connecting rod 65 is provided with a second air hole 651 coaxially arranged with the first air hole 71. The second air hole 651 is externally connected to an air supply device, and the air pipe of the air supply device is connected to the connecting rod 65 through a quick-connect connector. When the connecting rod 65 rotates, the air pipe will not be driven to rotate. At the same time, the compressed gas in the air pipe passes smoothly through the first air hole 71 and the second air hole 651.

[0034] Specifically, the connecting rod 65 includes a vertical rod portion 652 and a mounting portion 653. The driven gear 63 is sleeved on the vertical rod portion 652 and is locked by a screw so that the driven gear 63 drives the connecting rod 65 to rotate. A mounting hole matching the drill bit 7 is opened in the mounting portion 653, and a screw hole 654 connected to the mounting hole is provided on the side wall of the mounting portion 653. During installation, the drill bit 7 is inserted into the mounting hole, and a screw is threadedly connected to the screw hole 654 to lock the position of the drill bit 7. The above arrangement facilitates the installation and removal of the drill bit 7.

[0035] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
