Description

Technical Field

[0001] This utility model belongs to the technical field of jade processing equipment, specifically relating to a jade fine carving fixing component. Background Technology

[0002] Jade is carved and polished to bring out its natural beauty to the fullest. As people's living standards improve, their demands for jade carving are also constantly increasing.

[0003] In existing jade carving techniques, due to production capacity requirements, processing tasks are gradually shifting from manual to machine-based. Using clamps or related tooling, the jade is fixed in the machine's worktable, and then precision carving tools carve and polish its surface. This method significantly reduces labor costs and substantially increases production capacity, making it very popular among jade processing professionals.

[0004] However, when dealing with rounded-edge slabs, existing clamps are ineffective at holding them firmly, or require multiple clamping and processing steps, resulting in unsatisfactory carving effects. Alternatively, custom-made clamps are needed to hold the raw material, increasing carving costs. Using current tooling kits, however, necessitates drilling holes in the jade, inevitably damaging its structure and affecting its aesthetic appeal. Ultimately, considering the desired finish, a return to manual carving is necessary. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this utility model provides a jade carving fixing component. The jade piece, the blank plate, and the secondary fixing plate are respectively bonded and fixed by a second fixing adhesive and a first fixing component, thereby firmly fixing the jade piece on the worktable of the carving equipment. The fixing operation and subsequent cutting are simple, the fixing efficiency is high, and it can realize the three-dimensional fine carving process of the edge of the jade piece, realizing frameless jade carving processing.

[0006] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0007] This utility model provides a jade carving fixing component, which is set on the worktable of a carving machine and used to fix a jade piece with a rounded edge plate shape, including:

[0008] A secondary fixing plate is fixed to the workbench, including a first fixing surface facing away from the workbench;

[0009] A blank slab, disposed on the first fixing surface, includes a second fixing surface and a jade fixing surface disposed opposite to each other, the second fixing surface abutting against the first fixing surface; and

[0010] The adhesive kit includes a first fixing adhesive and a second fixing adhesive;

[0011] The blank plate has multiple adhesive grooves that penetrate the second fixing surface and the jade fixing surface along its edge. The first fixing adhesive is placed in the adhesive grooves and bonds the blank plate and the secondary fixing plate together. The jade piece in its blank state is bonded and fixed to the jade fixing surface by the second fixing adhesive.

[0012] In some implementations, at least one set of opposite edges of the blank plate is aligned with the edge of the first fixed surface.

[0013] In some implementations, the bonding groove is V-shaped or tooth-shaped.

[0014] In some implementations, when the bonding groove is "V" shaped, its maximum width at the edge of the blank is L, and the distance from the tip of the bonding groove to the edge of the blank is H. Then, there is a relationship between L and H: H≥1.5L.

[0015] In some implementations, the second fixing surface is a frosted surface, while the jade fixing surface is a smooth surface.

[0016] In some implementations, the blank board is an acrylic sheet or a plexiglass sheet; the secondary fixing plate is a bakelite block.

[0017] In some implementations, the first and second fixing adhesives are cyanoacrylate quick-drying adhesives.

[0018] In some implementations, a concave mold is provided on the first fixed surface, and the side of the jade piece away from the jade fixed surface is the first processing surface, and the shape of the first processing surface after processing matches the shape of the concave mold.

[0019] In some implementations, the second adhesive is bonded and fixed around the arc edge of the jade piece; the highest point where the second adhesive is bonded to the jade piece is below half the thickness of the raw jade piece.

[0020] In some implementations, the secondary fixing plate and the worktable have positioning holes and positioning elements respectively on their contacting sides. The positioning holes and positioning elements are inserted and matched to fix the position of the secondary fixing plate on the worktable. The secondary fixing plate also includes a clamping groove, which is provided on the edge of the secondary fixing plate. The worktable is provided with a clamping plate, which extends into the clamping groove to clamp and fix the secondary fixing plate on the worktable.

[0021] In summary, this utility model has at least the following advantages:

[0022] 1. The jade carving fixing component provided by this utility model uses a second fixing adhesive to bond and fix the jade piece to the blank plate, and then uses a first fixing adhesive to bond and fix the blank plate to the secondary fixing plate. This allows the rounded edge plate-shaped jade piece to be securely fixed on the worktable of the carving equipment without considering the clamping method or setting process holes. The entire fixing operation process is simple.

[0023] 2. The jade carving fixing component provided by this utility model has an adhesive groove, so the second fixing adhesive does not need to be bonded to the entire edge of the blank board and the secondary fixing board. This reduces the amount of second fixing adhesive used and ensures the fixing firmness while improving the bonding and fixing efficiency.

[0024] 3. The jade carving fixing component provided by this utility model ensures that there are no obstacles in the processing area of ​​the jade piece after fixing, making tool movement simple. During processing, the processing steps of the entire processing surface can be continuous, and the edges of the jade piece can also be processed with three-dimensional fine carving, realizing the processing of frameless jade carving products.

[0051] Example 1:

[0052] Please see Figures 1-3 As shown, this embodiment provides a jade carving fixing component 100, which is set on the worktable of a jade carving equipment for fixing a jade piece 300 with a rounded edge plate shape. The jade carving fixing component 100 includes a secondary fixing plate 1, a blank plate 2, and an adhesive kit 3. The jade piece 300, the blank plate 2, and the secondary fixing plate 1 are bonded and fixed by the adhesive kit 3, and then fixed together on the worktable 200 by the secondary fixing plate 1.

[0053] Specifically, the secondary fixing plate 1 is fixed to the workbench and includes a first fixing surface 11 facing away from the workbench. The blank plate 2 is disposed on the first fixing surface 11 and includes a second fixing surface 21 and a jade fixing surface 22 facing away from each other, with the second fixing surface 21 abutting against the first fixing surface 11. The adhesive kit 3 includes a first fixing adhesive 31 and a second fixing adhesive 32.

[0054] More specifically, multiple adhesive grooves 23 are provided along the edge of the blank plate 2, penetrating the second fixing surface 21 and the jade fixing surface 22. The first fixing adhesive 31 is placed in the adhesive grooves 23, and the blank plate 2 and the secondary fixing plate 1 are bonded and fixed together. The jade piece 300 in the blank state is bonded and fixed to the jade fixing surface 22 by the second fixing adhesive 32.

[0055] The rounded-edge jade piece 300 is generally used to make jade plaques, pendants, and other ornaments. It's essential to retain and process the rounded edges around its perimeter. If traditional clamps are used, custom-made clamps are required, and the position of the clamp must be carefully monitored during the fine carving process to avoid damaging the tools and clamps due to incorrect tool paths. However, by using a second fixing adhesive 32 to bond it to the blank plate 2, the jade piece 300 can be stably fixed to the worktable of the fine carving equipment without changing its shape or increasing costs. The jade piece 300 can be fixed solely with the second fixing adhesive 32, making the operation simple and easy to use. When processing the edges of the jade piece 300, it is only necessary to ensure that the bonding position of the second fixing adhesive 32 is not affected; the edge processing of the jade piece 300 can be completed without compromising the adhesion. No edge space needs to be reserved, achieving a borderless fine carving process.

[0056] The blank plate 2 is bonded and fixed to the secondary fixing plate 1, effectively increasing the space on the blank plate 2 for accommodating jade pieces 300. If the blank plate 2 is directly fixed to the worktable, clamping space needs to be reserved on the blank plate 2, reducing the space utilization rate of the blank plate 2 and also affecting the carving tool path. By bonding and fixing the blank plate 2 to the secondary fixing plate 1, more jade pieces 300 can be finely carved in one clamping, improving production efficiency and equipment utilization.

[0057] Generally, the blank plate 2 is bonded to the secondary fixing plate 1, with the first fixing surface 11 and the second fixing surface 21 abutting against each other. Then, the first fixing adhesive 31 is bonded to the edge where the blank plate 2 and the secondary fixing plate 1 are bonded together to achieve fixation. However, after fixing in the above way, the first fixing adhesive 31 has a relatively low stress resistance. If impurities, bubbles, or other defects appear at the bonding point, it is very easy for the adhesive to fall off due to uneven bonding force. Moreover, because the bonding area is relatively large, the time required for the first fixing adhesive 31 to solidify is long, which is both uneconomical and has low bonding efficiency.

[0058] In this embodiment, to improve the above-mentioned problems, an adhesive groove 23 is provided on the blank plate 2, and the first fixing adhesive 31 is disposed in the adhesive groove 23. Since the bonding position is different from the force-bearing surface, when the first fixing adhesive 31 is subjected to force, the force is distributed to multiple surfaces with different directions within the adhesive groove 23. This reduces the amount of first fixing adhesive 31 used while enhancing its load-bearing capacity and making it less prone to falling off. Preferably, the first fixing adhesive 31 should cover the surface and edge surface of the blank plate 2 at the adhesive groove 23 to further increase the bonding area of ​​the first fixing adhesive 31. Of course, the first fixing adhesive 31 can also continue to be bonded to the edges of the blank plate 2 and the secondary fixing plate 1 to strengthen the bonding firmness between the blank plate 2 and the secondary fixing plate 1.

[0059] In some embodiments, at least one set of opposite edges of the blank plate 2 are aligned with the edge of the first fixing surface 11. This alignment allows the first fixing adhesive 31 to achieve a larger bonding surface on both the blank plate 2 and the secondary fixing plate 1, improving its bonding strength. This also makes subsequent operations such as toolpath editing and zero-point setting of the worktable coordinates more convenient and efficient.

[0060] To further improve the bonding performance between the blank plate 2 and the secondary fixing plate 1, in some embodiments, the bonding groove 23 is configured in a "V" shape or a toothed shape. For example... Figure 4 As shown, the "V"-shaped or toothed structure has a recessed relative plane on the blank plate 2. After the first fixing adhesive 31 is bonded and fixed, its fixing effect is more reliable. When encountering processing loads on a horizontal surface, the load is distributed by the recessed plane, thereby improving the load-bearing capacity of a single bonding point. During processing, the above-mentioned adhesive groove 23 can be completed by cutting or milling. In some other embodiments, the adhesive groove 23 can also be set as an arc-shaped structure or a semi-circular arc structure. However, since the bonding and bearing surface with the first fixing adhesive 31 is reduced and the amount of the first fixing adhesive 31 used is higher, its bonding firmness and final load-bearing capacity are worse than those of the "V"-shaped or toothed adhesive groove 23.

[0061] Furthermore, please... Figures 1-4 Based on the above, refer to Figure 5 When the adhesive groove 23 is V-shaped, its maximum width at the edge of the blank plate 2 is L, and the distance from its tip 231 to the edge of the blank plate 2 is H. The relationship between L and H is: H ≥ 1.5L. In practical applications, to ensure balanced force distribution under load, the adhesive groove 23 is generally a symmetrical V-shaped structure. To improve the bonding strength, the area of ​​the inner surface of the adhesive groove 23 needs to be increased. When L and H satisfy H ≥ 1.5L, the adhesive groove 23 and the first fixing adhesive 31 can achieve good bonding effect and load-bearing capacity. Of course, due to geometric limitations, an excessively large H value means that the angle of the tip 231 of the adhesive groove 23 becomes smaller, which may easily lead to stress cracking under certain conditions. Due to the influence of various factors, such as the thickness of the blank plate 2, the cutting process of the adhesive groove 23, and the roughness of the inner surface of the adhesive groove 23 during molding, the specific values ​​of L and H need to be determined according to the actual situation, and will not be elaborated here.

[0062] To further enhance the bonding strength and load-bearing capacity between the blank plate 2 and the jade piece 300 and the secondary fixing plate 1, the second fixing surface 21 is frosted, while the jade fixing surface 22 is smooth. The frosted surface generates greater friction between the second fixing surface 21 and the first fixing surface 11, preventing misalignment between the blank plate 2 and the secondary fixing plate 1 during fine carving. Furthermore, the first fixing adhesive 31 can easily penetrate from the adhesive groove 23 into the space between the blank plate 2 and the secondary fixing plate 1, thereby improving the bonding strength.

[0063] In the bonding process between the jade fixing surface 22 and the jade part 300, theoretically, setting the jade fixing surface 22 to a frosted or rough surface would be more conducive to the firm bonding of the second adhesive 32. However, in practical applications, if the jade fixing surface 22 is frosted or rough before fixing the jade part 300, it is easy for dust to accumulate and is not easily noticed. Often, defects such as peeling of the second adhesive 32 only become apparent during subsequent processing. When the jade fixing surface 22 is set to a smooth surface, the above problems are avoided, and the load-bearing capacity after bonding can meet the actual needs of fine carving.

[0064] Specifically, the blank board 2 can be an acrylic sheet or a plexiglass sheet, which has low usage and replacement costs. The secondary fixing board 1 is a bakelite block, whose easy machining characteristics allow for the fabrication of a connection structure that matches the workbench 200. The first fixing adhesive 31 needs to be an adhesive that bonds acrylic or plexiglass to bakelite, and the second fixing adhesive 32 needs to be an adhesive that bonds jade to acrylic or plexiglass. Preferably, both the first fixing adhesive 31 and the second fixing adhesive 32 can be cyanoacrylate-based quick-drying adhesives. This reduces the possibility of using the wrong adhesive during the bonding process while meeting the bonding requirements of the various materials mentioned above, and also lowers the procurement cost of the bonding kit 3.

[0065] In summary, the jade carving fixing component provided by this utility model uses a second fixing adhesive to bond and fix the jade piece to the blank plate, and then uses a first fixing adhesive to bond and fix the blank plate to the secondary fixing plate. This allows the rounded edge plate-shaped jade piece to be securely fixed on the worktable of the carving equipment without considering the clamping method or setting process holes. The entire fixing operation process is simple.

[0066] Secondly, with the adhesive groove provided, the second fixing adhesive does not need to be bonded to the entire edge of the blank plate and the secondary fixing plate. This reduces the amount of second fixing adhesive used and ensures the fixing firmness while improving the bonding and fixing efficiency.

[0067] Furthermore, once fixed in place, the jade piece is unobstructed within its processing area, simplifying the cutting process. The entire processing surface can be continuously processed, and the edges of the jade piece can also be used for three-dimensional fine carving, enabling the production of frameless jade carvings.

[0068] Example 2:

[0069] This embodiment provides a jade carving fixing component 100, which is structurally optimized based on Embodiment 1. Please refer to... Figures 1-5 Based on the above, refer to Figures 6-8 .

[0070] The rounded-edge, plate-shaped jade piece 300 has two planes, both of which typically require carving. For ease of explanation, we will refer to the plane initially bonded to one side of the jade fixing surface 22 as the second processing surface 302, and the plane furthest from the jade fixing surface 22 as the first processing surface 301. Due to the limitations of the adhesive, if deeper carving is required, the already carved first processing surface 301 cannot be fixed to the jade fixing surface 22, preventing the second processing surface 302 from being carved using precision carving equipment.

[0071] In order to solve this problem, this embodiment provides a die 111 on the first fixed surface 11, and makes the shape of the first processing surface 301 after processing match the shape of the die 111.

[0072] After the fine carving of the first processing surface 301 is completed, the jade piece 300, together with the blank plate 2, detaches from the secondary fixing plate 1. The second fixing adhesive 32 is dissolved by spraying a solvent, and the jade piece 300 can then be separated from the blank plate 2. At the same time, the secondary fixing plate 1, which is still on the worktable of the fine carving equipment, can be processed by the fine carving tool 400 to process the concave mold 111 that matches the shape of the first processing surface 301.

[0073] After the die 111 is finished, the first machined surface 301 of the jade part 300 is reversed and placed into the corresponding die 111. At this time, the position of the jade part 300 is accurate and the second machined surface 302 is parallel to the machined horizontal plane of the worktable, thereby ensuring the accuracy of the cutting path of the second machined surface 302. In order to further fix the jade part 300, the adhesive kit 3 also includes a third fixing adhesive 33. The third fixing adhesive 33 is applied and bonded between the jade part 300 and the secondary fixing plate 1, and firmly bonds the jade part 300 and the secondary fixing plate 1 together. In some embodiments, the third fixing adhesive 33 may also be a cyanoacrylate quick-drying adhesive, just like the first fixing adhesive 31 and the second fixing adhesive 32.

[0074] Once the jade piece 300 is glued and fixed in place, the second processing surface 302 can be finely carved. Similar to the first processing surface 301, the processing range can cover the entire second processing surface 302, including its edges. After processing, the jade piece 300 can be removed, thus completing a jade carving product with deep textures on both sides and no border restrictions.

[0075] In some embodiments, the secondary fixing plate 1 can be made of bakelite board with a relatively thick height in the Z direction. After a batch of processing is completed, there is no need to replace the secondary fixing plate 1; the die 111 can be removed directly by milling off a certain height. If a new die 111 is needed, the secondary fixing plate 1 is reprocessed, thus achieving reuse and reducing the disassembly and assembly time of the secondary fixing plate 1.

[0076] To further improve processing efficiency and the performance of the fine carving equipment, a second fixing adhesive 32 is applied around the arc edge of the jade piece 300 to fix it to the jade fixing surface 22. The second fixing adhesive 32 can also be applied between the second processing surface 302 and the jade fixing surface 22. However, due to the characteristics of the second fixing adhesive 32, unevenness may occur on the first processing surface 301 after it dries, affecting the processing result. When the fine carving tool 400 is carving, its feed rate can be appropriately increased to improve the carving efficiency of the entire rough carving process.

[0077] Furthermore, if it is necessary to process the entire edge of the jade piece 300, and each edge can be processed precisely, then as follows: Figure 8 As shown, the highest point where the second fixing adhesive 32 adheres to the jade part 300 is below half the thickness of the jade part 300 blank. At this time, the first processing surface 301 is processed, and the carving tool 400 can carve along the upper half of the thickness of the jade part 300's edge. When processing the second processing surface 302, the concave mold 111 can be made shallower, and the adhesive is bonded between the first processing surface 301 and the secondary fixing plate 1, allowing the carving tool 400 to reach the edge of the jade part 300 and complete the edge carving.

[0078] Through the above methods, the 300-inch edge carving process for jade pieces, which could previously only be done manually, can now be achieved on precision carving equipment, greatly reducing the processing difficulty of such high-value jade products.

[0079] Example 3:

[0080] This embodiment, based on Embodiments 1 and 2, proposes a jade carving fixing component 100. Please refer to... Figures 1-8 Based on this, refer to Figures 9-10 The difference in this embodiment is that the secondary fixing plate 1 and the worktable 200 are respectively provided with positioning holes 12 and positioning elements 201 on the side that are in contact with each other. The positioning holes 12 and positioning elements 201 are inserted and cooperated to fix the position of the secondary fixing plate 1 on the worktable 200.

[0081] The secondary fixing plate 1 also includes a clamping groove 13, which is disposed on the edge of the secondary fixing plate 1. The worktable 200 is provided with a clamping plate 202, which extends into the clamping groove 13 to clamp and fix the secondary fixing plate 1 onto the worktable 200. In this embodiment, the clamping groove 13 is disposed on both sides close to the clamping plate 202. However, for a smaller secondary fixing plate 1, it can also be disposed on any two corners of the edge of the secondary fixing plate 1.

[0082] Through the positioning hole 12 and the positioning component 201, the secondary fixing plate 1 and the worktable 200 can achieve precision through the processing equipment used to process both, meeting the precision requirements during assembly and disassembly. The worktable 200 is equipped with a clamping plate 202, and the secondary fixing plate 1 is equipped with a clamping groove 13 for clamping and fixing. Compared with other fastening structures, such as screw fixing, this is more convenient and faster to operate, and the secondary fixing plate 1 experiences less wear during assembly and disassembly, which is beneficial for the mass production of the same jade carving products.

[0083] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
