[0002] Deep cavity machining is a common machining method in modern mechanical manufacturing technology, widely used in the manufacture of various mechanical parts.

[0003] However, traditional hydraulic tool holder design and manufacturing processes are costly, and due to structural limitations in machining, the appearance of hydraulic tool holders cannot be made extremely fine, failing to meet the requirements for machining certain deep cavities.

[0018] Access the additive weight database; the additive weight database includes at least: multiple apertures and weight percentage ranges corresponding to the apertures;

[0019] Traverse the additive manufacturing weight database, find the aperture corresponding to the clamping hole aperture in the additive manufacturing weight database, and obtain the corresponding weight percentage range;

[0020] Obtain a preset additive manufacturing specification, and process a cavity structure on the substrate structure according to the preset additive manufacturing specification and the weight ratio range.

[0021] According to the technical solution provided in this application, determining the processing reference based on the substrate structure specifically includes the following steps:

Detailed Implementation

[0039] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] To make the technical solution of this application clearer and easier to understand, the manufacturing method of the ultra-fine hydraulic tool holder provided in the embodiments of this application is described below with reference to the accompanying drawings. Figure 1 As shown in the figure, this is a flowchart of a method for manufacturing an ultra-thin hydraulic tool holder according to an embodiment of this application. The method includes the following steps:

[0042] S1. Obtain the first parameter set and process the base structure according to the first parameter set; the first parameter set includes: material information and size information of the base structure.

[0043] It should be noted that ultra-fine hydraulic tool holders refer to hydraulic tool holders with a wall thickness less than that of general-purpose hydraulic tool holders but greater than 3 mm, and a length greater than or equal to 150 mm. Here, the standard for general-purpose hydraulic tool holders is DIN69882-7.

[0044] The base structure includes at least a hydraulic tool holder interface structure and a structure for adjusting the hydraulic tool holder oil pressure. The specific method of machining the base structure is, for example, to connect the hydraulic tool holder interface structure to a CNC machine tool and then use the CNC machine tool for machining. Here, the specific structure of the CNC machine tool is not limited, as long as it can achieve machining.

[0045] The first set of parameters is, for example, that the material information is high-strength and wear-resistant mold steel, and the dimension information is that the straight-line distance from the hydraulic tool holder interface to the clamping hole of the hydraulic tool holder is 200mm, and the wall thickness of the clamping hole is 3-6mm. Here, the interface and clamping hole dimensions of the base structure can be set according to the actual order, and the thicker and shorter the base, the better the dimensional accuracy after printing.

[0046] S2. Call the material database to find the additive materials corresponding to the material information of the matrix structure in the material database; the material database includes at least: multiple material names and the corresponding material composition, material number and material properties.

[0047] The materials database is shown in Table 1.

[0048] Table 1 Materials Database

[0049] A001 a1, a2, a3 #011 High strength, wear-resistant A002 a2, a3 #022 High strength, wear-resistant, and tough A003 a1, a3, a4 #033 Wear-resistant and tough ... ... ... ... Axxx ax #xxx ...

[0050] It should be noted that the material database in Table 1 is only for illustrative purposes. For example, "Axxx" in Table 1 represents different material names, such as "A001" which represents a type of mold steel; "ax" in Table 1 represents different material compositions and their corresponding proportions, such as "a1" which represents carbon and its proportion; "#xxx" in Table 1 represents different material serial numbers, such as "#011" which represents mold steel with serial number 011.

[0051] As can be seen from the above, the material information of the matrix structure is high-strength and wear-resistant mold steel. The corresponding additive material, A001, can be found in the material database in Table 1.

[0052] Additionally, if no additive material that perfectly matches the matrix structure material information can be found in the material database, materials with similar compositions can be searched for in the database based on the specific material composition of the matrix structure. For example, if the carbon content in the matrix structure is 3%, other additive materials that meet the same conditions and whose carbon content differs from that of the matrix structure by ±0.5% can be searched in the material database. If two or more additive materials are found using this search method, the one with the smallest difference can be selected as the final additive material.

[0053] Here, the aforementioned difference range can be set according to actual needs.

[0054] S3. Determine the processing reference based on the base structure.

[0055] Among them, such as Figure 2 As shown, determining the processing datum based on the base structure specifically includes the following steps:

[0056] S31. The base structure is installed on the additive manufacturing tooling using the positioning structure.

[0057] It should be noted that additive manufacturing fixtures refer to 3D printing fixtures, which have a workstation for mounting the base structure. The specific structure of the 3D printing fixture is not limited here, as long as it enables additive manufacturing. Positioning structures include, for example, positioning blocks and locking screws. The base structure is mounted at the workstation of the 3D printing fixture, with the interface of the hydraulic tool holder in contact with the surface of the workstation. Then, the positioning block is placed in the gap between the base structure and the workstation, and the locking screw is used to connect the positioning block and the workstation, thereby restricting the relative position of the base structure and the workstation.

[0058] S32. Obtain the status information of the substrate structure and the additive manufacturing tooling; the status information includes: the perpendicularity information of the additive manufacturing tooling, the parallelism information between the substrate structure and the additive manufacturing tooling, and the flatness information of the surface where the additive manufacturing tooling is located.

[0059] Among these, a dedicated measuring instrument can be used to detect and obtain the status information of the substrate structure and additive manufacturing tooling.

[0060] S33. When the status information meets the preset status requirements, the extension line of the current surface contact position between the base structure and the additive manufacturing tooling is recorded as the machining reference.

[0061] Here, the preset state requirements refer to the perpendicularity of the additive manufacturing tooling being 0.1, the parallelism between the base structure and the additive manufacturing tooling being 0.1, and the flatness of the surface where the additive manufacturing tooling is located being 0.1. The data in the preset state requirements can be set according to the actual situation.

[0062] When the status information meets the preset status requirements, the extension line of the current contact position between the base structure and the workstation is recorded as the processing reference.

[0063] In addition, the method includes the following steps:

[0064] When the status information does not meet the preset status requirements, adjust the knob at the bottom of the additive manufacturing tooling until the status information meets the preset status requirements.

[0065] The additive manufacturing fixture has an adjustable support frame at its bottom. Adjusting the knobs on the support frame changes the fixture's verticality, the parallelism between the base structure and the fixture, and the flatness of the surface on which the fixture rests. Specifically, the support frame may consist of four support rods, each with a helical channel at one end. The head of an adjusting screw is rotatably connected to the bottom of the fixture, and the screw's shaft is screwed into the helical channel. A protrusion on the side wall of each support rod serves as a knob. Rotating the knobs rotates the support rod, thus changing the distance between the bottom of the helical channel and the free end of the adjusting screw. This allows adjusting the knobs on the support frame to change the fixture's verticality, the parallelism between the base structure and the fixture, and the flatness of the surface on which the fixture rests.

[0066] S4. Based on the processing benchmark, the cavity structure is processed on the matrix structure using additive materials.

[0067] Among them, such as Figure 3 As shown, the process of fabricating a cavity structure on a substrate structure using additive materials includes the following steps:

[0068] S41. Obtain the diameter of the clamping hole in the substrate structure.

[0069] The diameter of the clamping hole can be measured using a specialized measuring tool. Here, the clamping hole diameter refers to the inner diameter of the clamping hole.

[0070] S42. Call the additive weight database; the additive weight database includes at least: multiple apertures and the weight percentage range corresponding to the apertures.

[0071] The additive manufacturing weight database is shown in Table 2.

[0072] Table 2 Additive Manufacturing Weight Database

[0073] K1 D6 2.5％-10％ K2 D8 2.5％-10％ K3 D10 3％-10％ K4 D12 3％-10％ K5 D14 3％-10％ K6 D16 3.5％-11％ K7 D18 3.5％-11％ K8 D20 3.5％-12％ ... ... ... Kx Dx ...

[0074] It should be noted that in Table 2, "Kx" represents the sorting number of the aperture in the additive weight database from smallest to largest. For example, "K1" represents the aperture that is ranked first in the additive weight database. In Table 2, "Dx" represents different sizes of aperture. For example, "D6" represents an aperture of one size.

[0075] S43. Traverse the additive manufacturing weight database, find the hole diameter corresponding to the clamping hole diameter in the additive manufacturing weight database, and obtain the corresponding weight percentage range.

[0076] The weight percentage range refers to the proportion of the total weight of the cavity structure to be formed within the hydraulic tool holder. For example, if the clamping hole diameter is D16, the corresponding weight percentage range found in the additive manufacturing weight database is 3.5%-11%.

[0077] S44. Obtain the preset additive specifications, and process the cavity structure on the matrix structure according to the preset additive specifications and weight ratio range.

[0078] Among these, the preset additive specifications refer to the length, thickness, and inner diameter of the cavity structure to be formed. Furthermore, such as... Figure 4 As shown, according to the preset additive specifications and weight ratio range, the end of the substrate structure 01 away from its interface forms a processing start surface 03, and the cavity structure 02 is processed at the processing start surface 03.

[0079] S5. Heat treatment of the base structure and cavity structure to obtain an ultra-fine hydraulic tool holder.

[0080] Specifically, a heating mechanism is used to heat the base structure and cavity structure at a set temperature to improve mechanical or machining properties, thereby obtaining a high-quality ultra-fine hydraulic tool holder.

[0081] Furthermore, the method also includes the following steps:

[0082] Clean the burrs on the surface of the ultra-fine hydraulic tool holder; stop the cleaning operation when the surface flatness of the ultra-fine hydraulic tool holder is identified as being within the preset flatness range.

[0083] Specifically, surface burrs can be removed and cleaned using specialized tools. The preset flatness range is, for example, ±0.1, which can be set according to actual needs. The surface flatness of ultra-fine hydraulic tool holders can be detected using a specialized measuring instrument.

[0084] Furthermore, the method also includes the following steps:

[0085] Inspect the surface of ultra-fine hydraulic tool holders for defects;

[0086] If a defect exists, the product is marked as non-conforming; if no defect exists, the product is marked as conforming.

[0087] The presence of defects on the surface of the ultra-fine hydraulic tool holder can be determined by visual inspection or by using specialized testing instruments. This allows the molded ultra-fine hydraulic tool holder to be divided into different categories, facilitating subsequent research and production.

[0088] After processing the base structure according to the first parameter set, this application retrieves the additive material corresponding to the material information of the base structure from the material database. A processing datum is determined based on the base structure. Based on this datum, a cavity structure is processed on the base structure using the additive material. Then, the base structure and cavity structure are heat-treated to obtain a finished ultra-thin hydraulic tool holder. Compared to the traditional method of directly machining the entire hydraulic tool holder, this application uses a technology combining machining and additive printing, processing the base structure and cavity structure sequentially, and using similar or identical materials for both. This results in an ultra-thin hydraulic tool holder that can meet various deep cavity machining needs, while reducing processing difficulty and cost.
