Description

Technical Field

[0001] This utility model relates to the technical field of art carving fixing tools, and in particular to a fixing tool for art carving. Background Technology

[0002] In the field of art carving, the shapes of the workpieces to be carved are diverse, placing extremely high demands on the adaptability and stability of the fixing tools. Among existing art carving fixing tools, most adsorption-type fixing structures rely on the perfect fit between the bottom surface of the workpiece and the fixing platform. If the bottom surface of the workpiece is not tightly fitted to the fixing platform, insufficient adsorption force is easily encountered, causing the workpiece to shift and wobble during the carving process. This not only compromises carving accuracy but may also damage the workpiece, making it difficult to meet the stable fixing requirements of artworks of different shapes.

[0003] Meanwhile, carving operations generate a large amount of waste such as wood chips and stone chips. Existing adsorption-type fixing tools generally lack effective waste chip protection mechanisms. Waste chips can easily enter the adsorption channel with the adsorption airflow and then invade the internal air pump connected to the fixing tool, causing blockage and wear of the internal components of the air pump, increasing the frequency of equipment failure, and affecting the continuity of carving operations. Even if a few fixing tools are equipped with filter components, the installation method of their filter structure is mostly bolt fastening or one-piece molding design, and the disassembly and assembly process is cumbersome, making it inconvenient to clean and replace the filter components. This not only consumes a lot of maintenance time but also increases maintenance costs, making it difficult to meet the maintenance requirements of high-efficiency carving operations. Therefore, the above problems need to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixing tool for carving artworks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixing tool for carving artwork, comprising a support platform, with positioning platforms fixedly connected to both sides of the lower front and rear ends of the support platform; mounting holes are provided on both sides of the center of the top surface of the positioning platforms; and multiple limiting platforms are installed horizontally at equal intervals on the front and rear ends of the support platform; a moving groove penetrating the limiting platform is vertically provided on the top surface of the limiting platform; a fixing platform is installed on the top surface of the support platform; and limiting blocks that cooperate with the moving groove are installed on both the front and rear ends of the fixing platform.

[0006] Preferably, an adsorption chamber is provided below the inner cavity of the fixed platform, and a filtration chamber is provided at the upper end of the adsorption chamber. The filtration chamber is placed inside the fixed platform, and one side of the filtration chamber penetrates one side of the fixed platform. Multiple adsorption platforms are installed at equal intervals on the top surface of the fixed platform.

[0007] Preferably, the top surface of the adsorption platform is provided with a partition groove, the outer side of the partition groove is provided with a settling groove, a first filter screen is snapped into the settling groove, and an adsorption hole penetrating the top surface of the fixed platform is provided in the middle of the top surface of the partition groove. The lower end of the adsorption hole penetrates the top surface of the fixed platform and the bottom surface of the filter chamber and communicates with the adsorption chamber.

[0008] Preferably, a second filter screen with a handle on one side is slidably connected in the filter chamber, a suction nozzle is installed below the inner side of the adsorption hole, a sealing plate is installed in the middle of the front end of the fixed platform, an air extraction pipe is installed in the middle of the front end of the sealing plate, and an air extraction hole is opened at the front end of the fixed platform to cooperate with the air extraction pipe.

[0009] Preferably, the support platform has a buffer chamber, guide columns are installed on both the front and rear ends of the bottom of the fixed platform, and the top surface of the support platform has a guide hole for sliding with the guide columns.

[0010] Preferably, a spring is sleeved on the outer side of the guide post, and the two ends of the spring are fixed to the bottom surface of the fixed platform and the top surface of the support platform, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model provides a stable negative pressure to the suction nozzle through the cooperation between the suction pipe, the external suction pump, the adsorption chamber, and the adsorption hole. Even if the bottom surface of the workpiece is not completely attached to the adsorption platform, the small-diameter adsorption hole and the suction nozzle can still provide sufficient adsorption force to meet the fixing needs of artworks of different shapes. The first filter screen of the adsorption platform can initially block carving waste from entering the adsorption channel, and the second filter screen of the filter chamber forms secondary protection. The double filtration can effectively prevent waste from damaging the external suction pump and reduce equipment failure. Moreover, the first filter screen adopts a snap-fit ​​form and the second filter screen adopts a sliding pull-out form, which makes it easy to clean and replace the first and second filter screens regularly and reduces the difficulty of maintenance.

[0013] 2. This utility model uses the guide column of the fixed platform and the buffer chamber of the support platform to slide and limit the movement. With the spring on the outside of the guide column, it can provide a buffer for the fixed platform when adsorbing heavy artworks, so as to avoid damage to the workpiece due to gravity impact. The elastic support of the spring can also make the fixed platform adaptable to workpieces of different thicknesses without the need to replace special support components. This greatly improves the tool's adaptability to various artworks and reduces the cost of using special accessories. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: See Figures 1 to 4This utility model discloses a fixing tool for carving artwork, including a support platform 1. The support platform 1 facilitates the sliding connection and positioning of a fixing platform 4 with a guide column 11, a limiting platform 3, and a limiting block 5. Positioning platforms 2 are fixedly connected to the lower sides of the front and rear ends of the support platform 1, allowing for the use of external bolts and other components to secure the support platform 1 and prevent loosening during subsequent carving operations. Mounting holes are provided on both sides of the center of the top surface of the positioning platform 2, and multiple limiting platforms 3 are installed horizontally at equal intervals on the front and rear ends of the support platform 1. 3. To facilitate the subsequent installation of the limiting block 5 on the fixed platform 4, the limiting platform 3 has a vertically extending groove on its top surface. The fixed platform 4 is installed on the top surface of the support platform 1, which serves as a substrate for adsorbing the object to be engraved. Limiting blocks 5 that mate with the moving groove are installed on both the front and rear ends of the fixed platform 4. The limiting blocks 5 facilitate the limiting of the fixed platform 4 with the limiting platform 3, preventing the fixed platform 4 from becoming loose during subsequent engraving. An adsorption chamber 6 is provided below the inner cavity of the fixed platform 4, which facilitates the adsorption of the object to be engraved. The suction pipe 13 provides negative pressure suction to the top surface of the fixed platform 4. A filter chamber 7 is provided at the upper end of the adsorption chamber 6, through which the second filter screen 14 can be slidably connected. The notch in the filter chamber 7 that penetrates the fixed platform 4 needs to be sealed with an external component after the second filter screen 14 is installed. The filter chamber 7 is placed inside the fixed platform 4, with one side of the filter chamber 7 penetrating one side of the fixed platform 4. Multiple adsorption platforms 9 are equidistantly installed on the top surface of the fixed platform 4, facilitating the adsorption of objects to be polished by the fixed platform 4. A partition groove is provided on the top surface, and a settling groove is provided on the outside of the partition groove. A first filter screen 10 is snapped into the settling groove. The first filter screen 10 helps to block the waste from external grinding from entering the adsorption chamber 6 and protects the external air pump connected to the air extraction pipe 13. An adsorption hole 8 is provided in the middle of the top surface of the partition groove, which penetrates the top surface of the fixed platform 4. The adsorption hole 8 facilitates the connection with the adsorption chamber 6 so that when the adsorption chamber 6 generates negative pressure, the adsorption hole 8 also generates negative pressure. The lower end of the adsorption hole 8 penetrates the top surface of the fixed platform 4 and the bottom surface of the filter chamber 7 and connects with the adsorption chamber 6.

[0022] In this invention, a second filter screen 14 with a handle on one side is slidably connected inside the filter chamber 7, which serves as a second layer of filtration to prevent debris. A suction nozzle 16 is installed below the inner side of the adsorption hole 8, which provides negative pressure suction to the adsorption hole 8. A sealing plate is installed at the middle of the front end of the fixed platform 4, and an air extraction pipe 13 is installed at the middle of the front end of the sealing plate. The air extraction pipe 13 facilitates connection to an external air pump, and the air extraction hole 13 provides negative pressure to the adsorption chamber 6 under the action of the external air pump. The front end of the fixed platform 4 is provided with an air extraction hole for installation with the air extraction pipe 13, and the support platform 1... A buffer chamber 15 is provided, which facilitates the movement of the limiting guide post 11 and thus limits the fixed platform 4, allowing the fixed platform 4 to buffer when adsorbing larger items in conjunction with the spring 12. Guide posts 11 are installed on both the front and rear ends of the bottom of the fixed platform 4, which facilitates the limiting of the buffer chamber 15 provided by the support platform 1. The top surface of the support platform 1 has a guide hole that slides with the guide post 11, and a spring 12 is sleeved on the outside of the guide post 11. The two ends of the spring 12 are fixed to the bottom surface of the fixed platform 4 and the top surface of the support platform 1, respectively, which facilitates the support of the fixed platform 4 and also provides buffering for the fixed platform 4.

[0023] Working principle: When using this utility model, the operator, with the help of external bolts, places the support platform 1 on the design base of the grinding machine through the positioning platform 2. Then, the air extraction pipe 13 is connected to the external air extraction pump, and the second filter screen 14 is slidably connected into the fixed platform 4 through the filter chamber 7. Then, with the help of the external sealing component, the connection between the filter chamber 7 and the fixed platform 4 is sealed. After sealing, the operator can start the subsequent grinding work.

[0024] Then, the operator starts the external air pump, which draws air from the adsorption chamber 6 through the air extraction pipe 13, creating a negative pressure in the adsorption chamber 6. Since the filter chamber 7 and the adsorption hole 8 are both connected to the adsorption chamber 6, and a suction nozzle 16 is installed below the adsorption hole 8, the suction nozzle 16 will generate a negative pressure suction. The operator can then place the object to be polished on the fixed platform 4. The object to be polished is first supported by the adsorption platform 9. Since the object to be polished is plate-shaped, its bottom surface will be firmly attached to the adsorption platform 9, providing the optimal adsorption surface for the suction nozzle 16. Subsequently, the suction force generated by the suction nozzle 16 will tightly adsorb the object to be polished. During the adsorption process, the weight of the object to be polished will compress the spring 12, causing the fixed platform 4 to move downward under the constraints of the guide post 11, the buffer chamber 15, the limiting block 5, and the limiting platform 3. The limiting block 5 and the limiting platform 3 will also provide resistance to the negative pressure generated during polishing. The shearing and torsional forces generated; then, when facing a perfectly fitted plate to be polished, the external air pump maintains the same power to achieve the optimal adsorption force. When encountering a plate that is not perfectly fitted, the adsorption force can also reach the predetermined adsorption force. Because the pore size of the adsorption hole 8 is small, and the adsorption pore size of the nozzle 16 is smaller than that of the adsorption hole 8, even if the adsorption platform 9 and the plate to be polished are not completely fitted (there is a small gap), the weakening of its suction force does not affect the effective adsorption of the corresponding plate to be polished. When polishing a plate that is not perfectly fitted, the waste generated will be filtered for the first time by the first filter screen 10, then filtered for the second time by the second filter screen 14, and finally blocked by the nozzle 16 to prevent the waste from entering the adsorption chamber 6 and damaging the external air pump. According to the polishing cycle requirements, the first filter screen 10 needs to be cleaned every time the plate to be polished is replaced, and the second filter screen 14 needs to be replaced after one polishing cycle.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
