Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic part processing, and particularly relates to a lettering device for the surface of ceramic parts. Background Art

[0002] Ceramic parts are widely used in various industries in life. With the development of modern production technology, more and more processes have emerged in the surface processing of ceramic parts. Many ceramic production enterprises choose to engrave patterns or words on the surface of ceramics to increase the aesthetics of ceramics. Basically, all existing ceramics on the market have lettering or engraving. Existing ceramic lettering processing is basically completed manually by experienced engravers or by robotic arms.

[0003] For example, a bottle-shaped ceramic engraving internal expansion fixing device disclosed in the patent application No. CN202110196875.3 includes a base, a support groove plate, an extrusion trigger assembly, a top expansion assembly, etc.; a support groove plate is fixedly connected to the base, an extrusion trigger assembly is slidably connected to the support groove plate, and the top expansion assembly is arranged on the support groove plate. When the lower pressing slide plate moves downward through the bottom clamping assembly and contacts the pulling rod, the lower pressing slide plate pushes the pulling rod and the devices thereon to move downward, the second support spring is compressed, and the four-corner pull frame pulls the clamping swing rod to swing through the arc guide ring, so that the movable clamping block moves towards the bottle-shaped ceramic, and the movable clamping block clamps and fixes the lower part of the bottle-shaped ceramic, so that the bottle-shaped ceramic will not be displaced or tilted when the engraver engraves the bottle-shaped ceramic.

[0004] In the prior art, through the design of the movable clamping block and the conical fixing plate, the ceramic part can be stably clamped and fixed during the lettering process by the production personnel. However, there are still some deficiencies in the overall use process: some prior art uses an operating table to place and clamp the ceramic, but adopting such a ceramic fixing scheme will block the bottom of the ceramic part, thus affecting the lettering on the bottom of the ceramic part. Due to the angle problem, it will even affect the lettering process on the side surface of the lower half of the ceramic part. At the same time, the existing clamping mechanism will cause clamping damage to the contact surface of the ceramic part, affecting the finished product quality of the ceramic part; on the other hand, the existing clamping mechanism cannot quickly clean the outside of the ceramic part, so that a large amount of dust and dirt are easily adhered to the outer surface of the ceramic part during lettering, affecting the lettering quality. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a lettering device for the surface of ceramic parts. Through the design of the fixing component and the electric push rod, the device can extend the fixing component into the interior of the ceramic part to fix the ceramic, so that during the operation process, the surface of the ceramic part can be fully exposed for the production personnel to carry out lettering treatment; through the design of the annular air seat and the annular light belt, during the lettering process, the device can evenly send air flow and light to the surface of the operated ceramic part. The air flow can take away the debris generated on the surface of the ceramic part during the lettering process, and the light plays a lighting role. The two provide a better technical basis for the lettering operation of the production personnel.

[0006] In order to achieve the above object, the utility model provides the following technical solution: A lettering device for the surface of ceramic parts, including a base, a placement table is fixedly arranged on the base, a first support plate is fixedly arranged on one side of the base in the vertical direction, an upper annular seat is fixedly arranged on the upper end surface of the first support plate above the base, an upper turntable is rotatably arranged on the upper end surface of the upper annular seat, an electric push rod is fixedly arranged inside the upper turntable, and a fixing component is arranged at the output end of the electric push rod;

[0007] The fixing component includes a connection block fixedly arranged at the output end of the electric push rod, a plurality of arc plates are rotatably arranged inside the connection block, a rotating cylinder is rotatably arranged outside the connection block, a plurality of openings are arranged on the side surface of the rotating cylinder, and each arc plate passes through the opening and extends to the outside of the rotating cylinder. A one-way limiting component is also fixedly arranged on the upper side of the connection block.

[0008] During use, the ceramic part can be first placed on the placement table, and then the production personnel control the output end of the electric push rod to move downward and extend into the interior of the ceramic, and operate the fixing component on the output end of the electric push rod to fix the ceramic; the production personnel can rotate the rotating cylinder in the fixing component to control the opening or tightening of the plurality of arc plates, so that the fixing component can fix the ceramic from the inside, so that the outer surface of the ceramic can be fully exposed for the production personnel to carry out lettering operations; during the lettering process, the production personnel can also adjust the height of the ceramic part by adjusting the electric push rod and adjust the angle of the ceramic part by adjusting the upper turntable according to the operation requirements.

[0009] Preferably, a plurality of suction cups are arranged on the outer side surface of each arc plate. When the plurality of fixed arc plates are opened to fix the ceramic part, the suction cups will tightly adsorb on the inner surface of the ceramic part for further fixation.

[0010] Preferably, the one-way limit assembly includes a ratchet wheel arranged on the upper end surface of the connecting block, a ratchet pawl is rotatably arranged on the rotating drum, and a spring is arranged between one side of the ratchet pawl and the rotating drum. Considering that after the arc plate in the fixing assembly is opened, the fixing assembly must be stable for a period of time to allow the production personnel to engrave the ceramic piece, this solution sets a ratchet wheel and a ratchet pawl in the fixing assembly so that the placement table and the rotating drum can only cooperate in one-way transmission, so that after the arc plate is opened to fix the ceramic piece, the rotating drum cannot be reversed, and the arc plate cannot be retracted to loosen the ceramic piece.

[0011] Preferably, the upper end surface of the drum is provided with a corrugated handle. The corrugated handle is annular and fixedly arranged on the upper end surface of the drum, so as to facilitate production personnel to rotate the drum.

[0012] Preferably, a third support plate is fixedly arranged inside the rotating drum, a sliding groove is arranged on the third support plate, a ratchet operating rod is fixedly arranged on the upper end surface of the pawl, and the ratchet operating rod passes through the sliding groove and extends out of the upper end surface of the rotating drum. The ratchet pawl is arranged inside the rotating drum, and the ratchet operating rod extends out of the upper end surface of the rotating drum for the convenience of the operator, and the sliding groove limits the operating rod, so that the pawl has only two states: biting the ratchet wheel and releasing the ratchet wheel.

[0013] Preferably, a second support plate is fixedly provided on one side of the upper annular seat, a clamping bolt is rotatably provided in the second support plate, and the lower end surface of the clamping bolt abuts against the upper end surface of the upper turntable. During operation, the production staff needs to rotate the upper turntable to adjust the angle of the ceramic piece, but after the adjustment, the upper turntable needs to be fixed to make the engraving process more stable. At this time, the production staff can rotate the clamping bolt so that the lower end surface of the disc-shaped bolt abuts downward against the upper end surface of the upper turntable to perform the clamping and fixing operation.

[0014] Preferably, the upper end surface of the base and the lower end surface of the upper annular seat are both provided with two annular air supply seats, and the annular air supply seat is connected to one side of the first support plate and provided with an air supply channel, and the other end of the air supply channel is fixedly provided with an air pump. The air pump can pump airflow, and continuously deliver the airflow to the air supply seat through the air supply channel, and then the airflow evenly sprays the gas to the ceramic surface through the air supply seat to take away the ceramic debris generated by the engraving process.

[0015] Preferably, each of the annular air supply seats is fixedly provided with an annular light belt on one end surface close to the ceramic. The annular light belt is used for lighting treatment, and the light belt is annular, so that the light falling on the surface of the ceramic piece is more uniform, which is convenient for production personnel to observe and operate.

[0016] In summary, compared with the prior art, the beneficial effects of this solution are:

[0017] Through the design of the fixing component and the electric push rod, the equipment of the utility model can extend the fixing component into the interior of the ceramic part to fix the ceramic, so that during the operation process, the dead corners on the surface of the ceramic part are reduced, and the ceramic part can be fully exposed for the production personnel to engrave characters on it.

[0018] Through the settings of the rotating cylinder, the connecting block, the arc plate and the suction cup, etc., the fixing component of the utility model can not only perform adaptive clamping and fixing processing on ceramic parts of different shapes and sizes, but also avoid damage to the internal contact surface of the ceramic parts, effectively improving the applicability of the equipment.

[0019] (3) Through the design of the annular air seat and the annular light belt, during the engraving process, the equipment of the utility model can evenly send air flow and light to the surface of the ceramic part being operated. The air flow can take away the debris generated on the surface of the ceramic part during the engraving process, and the light plays an illuminating role. The two provide a better technical basis for the engraving operation of the production personnel. Brief Description of the Drawings

Specific implementation manner

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Embodiment 1:

[0034] Refer to attached Figure 1 and attached Figure 2 and attached Figure 3 and attached Figure 4 as well as attached Figure 6 , a lettering device for the surface of a ceramic part, including a base 10, a placement table 31 is fixedly arranged on the upper end surface of the base 10, a first support plate 16 is fixedly arranged in the vertical direction on one side of the base 10, an upper annular seat 17 is fixedly arranged on the upper end surface of the first support plate 16 above the base 10, a second support plate 18 is fixedly arranged on one side of the upper annular seat 17, a compression bolt 19 is rotatably arranged inside the second support plate 18, an upper turntable 15 is also rotatably arranged on the upper end surface of the upper annular seat 17, the lower end surface of the compression bolt 19 cooperates with the upper end surface of the upper turntable 15, an electric push rod 20 is fixedly arranged in the vertical direction inside the upper turntable 15, a connecting block 33 is fixedly arranged on the lower end surface of the output end of the electric push rod 20, and a fixing component is arranged on the connecting block 33.

[0035] Production personnel can first place the ceramic part 21 on the placement table 31, then control the output end of the electric push rod 20 to move downward close to the ceramic part 21, and extend the fixing component on the output end of the upper annular seat 17 into the interior of the ceramic part 21. Subsequently, the ceramic part 21 is fixed on the output end of the electric push rod 20 with the fixing component. After the fixing is completed, the production personnel can operate the output end of the electric push rod 20 to move upward so that the ceramic part 21 rises with the output end of the electric push rod 20.

[0036] The fixing component fixes the ceramic part 21 from the inside of the ceramic part 21. After the ceramic part 21 rises with the output end of the electric push rod 20, the surface of the ceramic part 21 will be completely exposed, facilitating the engraving operation by production personnel. The electric push rod 20 is an existing technology and will not be elaborated in this solution.

[0037] After the ceramic part 21 rises with the output end of the electric push rod 20, production personnel perform lettering on it. The upper turntable 15 above the base can be rotated manually by production personnel to facilitate operations on the ceramic part 21 at different angles. When production personnel adjust the angle, they can rotate the pressing bolt 19 in the second support plate 18 to press the upper turntable 15 downward and fix it, thus ensuring the stability of the lettering process of the ceramic part 21 by production personnel. In this solution, the upper turntable 15, the second support plate 18, and the pressing bolt 19 are all existing technologies and will not be elaborated in this solution.

[0038] Further, refer to Appendix Figure 3 Appendix Figure 6 Appendix Figure 8 Appendix Figure 9 And Appendix Figure 11 , the fixing component includes arc plates 22 rotatably arranged in the connecting block 33. A plurality of suction cups 23 are fixedly arranged on the outer side surface of each arc plate 22. A rotating cylinder 24 is also rotatably arranged outside the connecting block 33. A circle of corrugated handles 25 is fixedly arranged on the upper end surface of the rotating cylinder 24. A plurality of openings 32 are also arranged on the side surface of the rotating cylinder 24. Each arc plate 22 passes through the corresponding opening 32 and extends outside the rotating cylinder 24. When production personnel rotate the rotating cylinder 24 through the corrugated handle 25, the openings 32 on the rotating cylinder 24 will change the position of the arc plate 22, making the arc plate 22 present different opening angles.

[0039] Further, refer to Appendix Figure 3 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 11 And Appendix Figure 12 , when the fixing component extends into the inside of the ceramic part 21, production personnel rotate the corrugated handle 25 to open the plurality of arc plates 22 in the connecting block 33 to support the inner wall of the ceramic part 21. At the same time, a plurality of suction cups 23 on the outer side surface of each arc plate 22 will tightly adsorb the inner wall of the ceramic part 21, playing a further fixing role on the ceramic part 21. The fixing component extends into the ceramic part 21 and opens the arc plates 22 to fix the inner wall of the ceramic part 21. For the fixing situation, refer to Appendix Figure 3 And Appendix Figure 5 ; For the comparison between the tightened state and the opened state of the fixing component, refer to Appendix Figure 6 And Appendix Figure 7 ; When the fixing component is in different states, for the situation where the arc plates 22 cooperate with the rotating cylinder 24 to tighten and open, refer to Appendix Figure 11 And AppendixFigure 12 。

[0040] Further, referring to the attached Figure 8 , the attachment base 9, the attached Figure 10 , a ratchet wheel 26 is fixedly arranged on the upper end face of the connecting block 33, a pawl 27 is rotatably arranged at the same horizontal level as the ratchet wheel 26 on the upper side of the rotating cylinder 24, and a spring 28 is arranged on one side of the pawl 27 to connect the rotating cylinder 24. Considering that after the arc plate 22 in the fixing component is opened, the fixing component must stably fix the ceramic part 21 for a certain period of time to allow the production personnel to engrave the ceramic part 21. In this solution, a ratchet wheel 26 and a pawl 27 are arranged in the fixing component so that the connecting block 33 and the rotating cylinder 24 can only be in one-way transmission cooperation. Thus, after the arc plate 22 is opened to fix the ceramic part 21, the rotating cylinder 24 cannot reverse, and the arc plate 22 cannot retract to release the ceramic part 21. The ratchet wheel 26 and the pawl 27 are both prior arts, and this solution will not be elaborated too much.

[0041] Further, referring to the attached Figure 5 , the attached Figure 9 and the attached Figure 10 , a third support plate 30 is fixedly arranged in the rotating cylinder 24 above the connecting block 33. A sliding groove 34 is arranged on the third support plate 30. A pawl operating rod 29 is fixedly arranged on the upper end face of the pawl 27. The pawl operating rod 29 passes through the sliding groove 34, and the pawl operating rod 29 can slide in cooperation with the sliding groove 34 in the sliding groove 34. When the production personnel finish processing, it is necessary to make the fixing component release the ceramic part 21. At this time, it is necessary to make the pawl 27 release the ratchet wheel 26 so that the rotating cylinder 24 can reverse, thereby driving the arc plate 22 to tighten and release the ceramic part 21. The ratchet wheel 26 and the pawl 27 are both arranged in the rotating cylinder. The pawl operating rod 29 extends out of the upper end face of the rotating cylinder, which is convenient for the operator to operate. The sliding groove 34 limits the operating rod, so that the pawl has only two states: biting the ratchet wheel and releasing the ratchet wheel. When the fixing component extends into the ceramic part 21 for fixing, both the pawl operating rod 29 and the corrugated handle 25 are higher than the upper end face of the ceramic part 21, and the production personnel can still control the rotation of the rotating cylinder 24 by operating the corrugated handle 25, and control the pawl 27 to bite or release the ratchet wheel 26 by operating the pawl operating rod 29.

[0042] Specifically, initially, the production personnel can place the ceramic part 21 on the placement table 31. Subsequently, the production personnel control the output end of the electric push rod 20 to move downward until the fixing component on the output end of the electric push rod 20 enters the ceramic part 21. After the operation is completed, the production personnel perform a fixing operation on the ceramic part 21. First, the rotating cylinder 24 is rotated through the corrugated handle 25, and the multiple openings 32 on the rotating cylinder 24 will drive the multiple arc plates 22 to open and approach the inner wall of the ceramic part 21 until the multiple arc plates 22 are closely attached to the inner wall of the ceramic part 21. A plurality of suction cups 23 are arranged on the outer side of each arc plate 22. During the fixing process, the plurality of suction cups 23 will tightly suck the inner wall of the ceramic part 21, further fixing the ceramic part 21.

[0043] After the fixing is completed, the production personnel can control the output end of the electric push rod 20 to rise. At the same time, the fixing component and the ceramic fixed thereon will follow the output end of the electric push rod 20 to rise. After rising to an appropriate height, the production personnel can perform engraving on the ceramic part 21. The height to which the electric push rod 20 rises refers to the operation requirements of the specific production site. The production personnel can continuously adjust the height according to the operation requirements at different angles, and this scheme is not restricted.

[0044] During the engraving process, if the production personnel need to rotate the ceramic part 21 for operation, they can adjust the angle by rotating the upper turntable 15 above the rotating base 10. When rotating the upper turntable 15 to adjust the angle, the production personnel need to first rotate the compression bolt 19 in the second support plate 18 to loosen the upper turntable 15, so that the upper turntable 15 can rotate freely according to the needs; after the adjustment is completed, the production personnel can rotate the compression bolt 19 in the second support plate 18 to press the upper turntable 15, so that the compression bolt 19 presses and fixes the upper turntable 15, thus ensuring the stability of the ceramic part 21 during the engraving process by the production personnel.

[0045] After the engraving process is completed, the production personnel can operate the ratchet pawl operating rod 29 to release the ratchet pawl 27 from the ratchet wheel 26, so that the rotating cylinder 24 that can only be operated unidirectionally can be reversed according to the needs. The reverse rotation of the rotating cylinder 24 will drive the opened arc plates 22 to retract back to the tightened state. During this process, the arc plates 22 will release the ceramic part 21, and the production personnel can then remove the processed ceramic part 21. Subsequently, the production personnel can control the output end of the electric push rod 20 to move upward back to the initial position. Embodiment 2:

[0046] Refer to the appendix Figure 1 and the appendix Figure 3 and the appendix Figure 4, a cutting device for processing the brackets of solar photovoltaic panels. An annular air supply base 11 is also fixedly arranged on the upper end surface of the base, and an annular light belt 13 is fixedly arranged on the upper end surface of the annular air supply base 11. Similarly, an annular air supply base 11 is also fixedly arranged on the lower end surface of the upper annular seat 17, and an annular light belt 13 is fixedly arranged on the lower end surface of the annular air supply base 11. Each annular air supply base 11 is connected with an air supply channel 12 on the side close to the first support plate 16, and the other end of the air supply channel 12 is fixedly provided with an air pump 14. In this solution, the air pump 14 is a prior art and will not be elaborated in this solution.

[0047] As a further embodiment, the air pump 14 can be used as a gas source to send air flow into the annular air supply base 11 through the air supply channel 12. Subsequently, the air flow is evenly sprayed from the annular air supply base 11 onto the surface of the ceramic part 21 and takes away the debris generated during engraving, so as not to affect the subsequent engraving operation. The setting of the annular light belt 13 plays a role in lighting, facilitating the production personnel to observe and operate on the ceramic part 21. Both the annular air supply base 11 and the annular light belt 13 are annular, so that the air flow and light can reach the surface of the ceramic part 21 more evenly.
