[0001] The invention relates to the technical field of production and processing of ceramic rollers, and in particular to an automatic drilling machine for ceramic roller blanks. Background Art

[0002] Ceramic roller is an important industrial ceramic product, mainly used in industrial production under high temperature, high pressure and high speed. It is usually made of high-purity ceramic material, with the characteristics of high temperature resistance, wear resistance and chemical stability, suitable for rolling processing of materials such as steel and aluminum alloy. In the current processing flow, it is necessary to pre-drill a hole at one end of the unfired blank of the ceramic roller, wait for it to be fully dried, pass through the fixing pin and hang it on the kiln beam for sintering, and finally process it into a ceramic roller.

It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0027] Embodiment: An automatic drilling machine for ceramic roller blanks, such as Figure 1-Figure 7 As shown, it includes a workbench 1, a carrying plate 11, a support plate 12, a drill 13 and a nozzle Ⅰ 14. The workbench 1 is fixedly connected with the carrying plate 11. The width of the carrying plate 11 is less than the length of the ceramic roller blank. The front end of the carrying plate 11 is slightly higher than the rear end. The ceramic roller blank will slowly roll from the front end to the rear end when no external force is applied. The left and right ends of the top of the workbench 1 are connected with the support plates 12. The drill 13 is installed on the support plate 12. The drill 13 is connected with the nozzle Ⅰ 14. The nozzle Ⅰ 14 is connected to a water pipe, and the nozzle of the nozzle Ⅰ14 is aligned with the position of the hole drilled by the drill 13. The nozzle Ⅰ14 is used to cool the drill bit of the drill 13 and flush out the debris of the ceramic roller blank. It also includes a fixing mechanism 2, a positioning component 3 and a cleaning component 4. The support plate 12 is provided with a fixing mechanism 2 for clamping and fixing the ceramic roller blank from both ends, and the positioning components 3 for aligning the position of the ceramic roller blank are provided on both sides of the carrier plate 11. The support plate 12 is provided with a cleaning component 4 for flushing the inside of the ceramic roller blank.

[0028] like Figure 3-Figure 5As shown, the fixing mechanism 2 includes a motor 21, a gear 22, an upper guide frame 23, a lower guide frame 231, a sliding rod 24, a tightening half ring 25, a rubber pad 251, a rack 26 and a connecting piece 27. The upper guide frame 23 is connected to the top of the support plate 12, and the lower guide frame 231 is connected to the bottom of the load-bearing plate 11. The sliding rod 24 is slidably connected to the upper guide frame 23 and the lower guide frame 231. The bottom sides of the sliding rod 24 connected to the upper guide frame 23 are connected to the tightening half rings 25, and the top sides of the sliding rod 24 connected to the lower guide frame 231 are connected to the tightening half rings 25. The tightening half rings 25 on the same side form a complete circular ring, and the diameter of the circular ring is the same as the outer ring of the ceramic roller blank. The diameters are equal, and a rubber pad 251 is connected to the inner wall of the tightening half ring 25. Motors 21 are installed at the bottom of the two support plates 12. The drill 13 and the motor 21 are connected to each other by wire to reduce the time difference of signal transmission during control. The output shaft of the motor 21 passes through the support plate 12, and the end of the output shaft of the motor 21 is connected to a gear 22. The left and right sides of the sliding rod 24 are fixedly connected with connecting parts 27, and a rack 26 is connected to the connecting part 27, and the rack 26 is meshed with the gear 22. The connecting part 27 at the upper end of the ceramic roller blank, the rack 26 is located at the bottom of the connecting part 27, and the connecting part 27 at the lower end of the ceramic roller blank, the rack 26 is located at the top of the connecting part 27.

[0029] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the positioning assembly 3 includes an extrusion rod 31, a support rod 32, a positioning frame 33, a triangular block 331, an elastic member 34 and a frustum 35. Two support rods 32 are connected to both sides of the support plate 11, and the positioning frame 33 is slidably connected to the support rod 32. For the support plate 12 and the positioning frame 33 on the same side, two triangular blocks 331 are arranged on the side of the positioning frame 33 close to the support plate 12, and a frustum 35 is arranged on the side of the positioning frame 33 away from the support plate 12. A vent hole 351 is opened in the middle of the frustum 35, and the diameter of the frustum 35 is equal to the inner ring diameter of the ceramic roller blank. The sides of the connecting members 27 at the upper and lower ends are connected to the extrusion rod 31, and the extrusion rod 31 is matched with the triangular block 331 for transmission. An elastic member 34 is sleeved on the positioning frame 33, and one end of the elastic member 34 is connected to the support rod 32, and the other end is connected to the positioning frame 33.

[0030] like Figure 4 and Figure 6 As shown, the cleaning assembly 4 includes a support frame 41, a guide tube frame 42 and a nozzle II 43. For the two support plates 12, the adjacent sides are connected to the support frame 41, and the separated sides are connected to the guide tube frame 42. The nozzle II 43 is installed on the support frame 41, and the nozzle of the nozzle II 43 is aligned with the side of the ceramic roller blank. The tail of the nozzle II 43 is connected to the water pipe, and the water pipe is connected through the guide tube frame 42.

[0031] The staff puts the ceramic roller blank that needs to be drilled on the supporting plate 11, or conveys the ceramic roller blank to the front end of the supporting plate 11 through the conveying mechanism of the previous process, and then the staff pushes the arranged ceramic roller blanks to move backward and drills holes in turn. When the ceramic roller blank is close to the drill 13, it needs to pass through the positioning frame 33 of the positioning component 3. The positioning frame 33 will align the horizontal positions of the ceramic roller blank with each other so that the positions of the holes drilled at both ends are symmetrical. Then, when drilling, the tightening half ring 25 of the fixing mechanism 2 clamps and fixes the ceramic roller blank from the upper and lower ends, so that when drilling, When the ceramic roller blank does not rotate, the nozzles Ⅰ14 and Ⅱ43 will continue to spray water, which can not only cool the drill bit of the drill 13, but also timely flush out the debris generated when the ceramic roller blank is drilled, thereby ensuring the effect of drilling. At the same time, the inside of the ceramic roller blank does not need to be cleaned again, the manual operation steps are few, the drilling is more efficient, and the advantages of accurate drilling are also taken into account. The staff of the ceramic roller blank that has completed the drilling pushes it backwards, leaves the tightening semi-ring 25, and continues to move backwards. The staff at the rear end of the carrying plate 11 collects the ceramic roller blank that has completed the drilling, and continues to work to complete the drilling of the ceramic roller blank;

[0032] As for the fixing mechanism 2 for fixing the ceramic roller blank, it should be supplemented that when the ceramic roller blank to be drilled moves between the tightening semi-rings 25, the two motors 21 are turned on. Since the drill 13 and the motor 21 are wired to each other, the time difference of signal transmission during control can be reduced, thereby maintaining simultaneous start and stop. The motor 21 drives the gear 22 to rotate through the output shaft, and the gear 22 drives the meshing rack 26 to move up and down respectively. The rack 26 connected to the sliding rod 24 connected to the upper guide frame 23 through the connecting piece 27 slides downward, and the rack 26 connected to the lower guide frame 231 slides upward. Through the transmission sequence of gear 22-rack 26-connecting piece 27-sliding rod 24-tightening semi-ring 25, the rotating gear 22 causes the tightening semi-ring 25 at the upper end to move downward to extrude the ceramic roller blank, and causes the tightening semi-ring 25 at the lower end to move upward to extrude the ceramic roller blank, thereby pressing the ceramic roller blank at both ends. The motor 21 is fixed, and the inner ring of the tightening semi-ring 25 is provided with a rubber pad 251. The rubber pad 251 forms a sufficiently large static friction force with the surface of the ceramic roller blank to limit the rotation and sliding of the ceramic roller blank, so that it can remain stable during drilling, so that the drilling position is accurate, and the drill 13 is turned on, the drill bit is fed downward, and the nozzle moves with the drill bit to drill the ceramic roller blank. After the drilling is completed, the drill bit moves up and leaves the ceramic roller blank, and the motor 21 is reversed, and the gear 22 is reversed to make the rack 26 move in the opposite direction. Through the transmission sequence of gear 22-rack 26-connecting piece 27-sliding rod 24-tightening semi-ring 25, the tightening semi-ring 25 at the upper end moves upward to leave the ceramic roller blank, and the tightening semi-ring 25 at the lower end moves downward to leave the ceramic roller blank, thereby releasing the fixation of the ceramic roller blank. The staff pushes the ceramic roller blank to replace it and drills the next ceramic roller blank.

[0033] When the ceramic roller blank is fixed, the extrusion rod 31 moves with the connecting piece 27, and the distance between the extrusion rod 31 and the triangular block 331 is closer, so before the tightening half ring 25 and the ceramic roller blank come into contact, the extrusion rod 31 has pushed the triangular block 331 on the positioning frame 33 to move, and the extrusion rod 31 squeezes the triangular block 331, thereby pushing the two positioning frames 33 to the middle position, and at the same time stretching the elastic member 34, the round table 35 is inserted into the ceramic roller blank, thereby limiting the front and rear position of the ceramic roller blank. The diameter of 35 is equal to the inner diameter of the ceramic roller blank, so the gas is discharged through the vent hole 351 when entering, and then the moving positioning frame 33 squeezes the ceramic roller blank to align the ceramic roller blank, thereby limiting the left and right positions of the ceramic roller blank. At this time, the squeezing rod 31 has already abutted against the outermost end of the triangular block 331, and then the tightening half ring 25 contacts the ceramic roller blank, further limiting the rotation and movement of the ceramic roller blank, and the distance from the round table 35 entering the ceramic roller blank is greater than the distance from the end of the ceramic roller blank to the drill hole. The distance between the two truncated cones 35 and the ceramic roller blank is such that the debris generated by the drilling is blocked outside the truncated cone 35. In addition, the water flow ejected from the nozzle II 43 forms a relatively closed space with the two truncated cones 35 and the ceramic roller blank, and the diameter of the vent hole 351 is very small. When the water flow passes through the vent hole 351, it is affected by the internal pressure, so the water flow cannot pass through the vent hole 351. The drilling is completed. When the tightening half ring 25 leaves the ceramic roller blank, the connecting piece 27 drives the extrusion rod 31 to move. After the tightening half ring 25 leaves the ceramic roller blank, , the extrusion rod 31 gradually contacts with the inclined surface of the triangular block 331. When the extrusion rod 31 contacts with the inclined surface of the triangular block 331, the elastic member 34 rebounds, the positioning frame 33 and the round table 35 separate from the ceramic roller blank, and finally the extrusion rod 31 separates from the triangular block 331, all parts stop moving, and the staff pushes the ceramic roller blank, roughly pushing a ceramic roller blank between the two round tables 35. After completing the drilling of all the ceramic roller blanks, the drill 13, the motor 21, the nozzle I 14 and the nozzle II 43 are turned off.

[0034] like Figure 8 and Fig. 9 As shown, it also includes an open front plate 5 and a flat rear plate 51. The open front plates 5 are connected to the left and right sides of the front end of the workbench 1. The left open front plate 5 is inclined to the left, and the right open front plate 5 is inclined to the right. The flat rear plates 51 are connected to the left and right sides of the rear end of the workbench 1. The height of the triangular block 331 is greater than the horizontal distance between the open front plate 5 and the inner end surface of the positioning frame 33 on the same side. Therefore, after the ceramic roller blank passes through the open front plate 5, it will not be blocked by the end group of the positioning frame 33, and the ceramic roller blank will definitely pass through the sliding positioning frame 33.

[0035] When placing the ceramic roller blank, the open front plate 5 inclined on both sides can facilitate the staff to place the ceramic roller blank without accurately aligning the middle position of the supporting plate 11. The flat rear plate 51 can ensure that the ceramic roller blank with completed drilling leaves the supporting plate 11 straightly, which is convenient for taking it or entering the next step.

[0036] like Figure 8 As shown, it also includes a collecting frame 6 and a filter plate 61. The collecting frame 6 is installed on the left and right sides of the bottom of the workbench 1. The filter plate 61 is slidably connected in the collecting frame 6. The collecting frame 6 is located at the bottom of the drill 13, and a water pipe interface is provided at the bottom of the collecting frame 6, so that the filtered water can be reused.

[0037] The water sprayed from nozzles Ⅰ14 and Ⅱ43 flows into the collection frame 6 after passing through the ceramic roller blank, the debris is filtered by the filter plate 61, and the clean water is recycled through the bottom of the collection frame 6. After the drilling work is completed, the filter plate 61 is pulled out to clean the collected debris.

[0038] like Figure 8 and Fig. 9 As shown, it also includes a guide rod 7 and a limit frame 71. Multiple guide rods 7 are connected to the front and rear sides of the bottom of the supporting plate 11. The multiple guide rods 7 are slidably connected to the limit frame 71 together. The middle of the limit frame 71 is fixedly connected to the sliding rod 24 connected to the lower guide frame 231, and the limit frame 71 passes through the front and rear sides of the supporting plate 11.

[0039] When the sliding rod 24 moves up and down, the limit frame 71 moves along with it. When the limit frame 71 rises, it can block the ceramic roller blanks outside the carrying plate 11 from entering, limit the number of ceramic roller blanks on the carrying plate 11, protect the undrilled ceramic roller blanks from being hit by other ceramic roller blanks at a long distance, and block the drilled ceramic roller blanks from easily sliding off the carrying plate 11, so that the staff can leave for a period of time, thereby optimizing the operating difficulty of the staff.

[0040] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the appended claims of the application.
