[0056] Referring to Figures 1 to 9 The present application provides a machining method for intelligent manufacturing of box type parts 1, comprising the following steps S1-S4:

[0057] S1, quick-change positioning device manufacturing:

[0058] The quick-change positioning device comprises a quick-change supporting plate 2 and a cushioning block 3, the upper end of the quick-change supporting plate 2 is provided with a positioning base surface 22, the cushioning block 3 can be detachably fixed and installed at different positions of the positioning base surface 22, the upper end of the cushioning block 3 is provided with a supporting plane 31, a groove 32 is formed on the supporting plane 31, and the groove 32 extends to the side wall of the cushioning block 3 to form a notch.

[0059] In the embodiment, as a preferred design, the cushioning block 3 is in a cylindrical shape, and the bottom end plane thereof is attached to the positioning base surface 22 of the quick-change supporting plate 2. Preferably, the cushioning block 3 in the quick-change positioning device is provided in multiple types, including a planar type cushioning block and an inclined type cushioning block, wherein the supporting plane 31 of the planar type cushioning block is parallel to the positioning base surface 22 after being installed on the positioning base surface 22, that is, the supporting plane 31 is parallel to the bottom end plane, and the supporting plane 31 of the inclined type cushioning block is inclined to the positioning base surface 22 after being installed on the positioning base surface 22, that is, an inclined angle is formed between the supporting plane 31 and the bottom end plane, and the inclined angle is referred to as the inclination angle of the inclined type cushioning block. The inclined type cushioning block 3 has multiple inclination angles, for example, thirteen inclination angles can be obtained by taking every 5° as an inclination angle in the range of 5° to 60°. Further preferably, the planar type cushioning block has multiple different height sizes, and each inclination angle of the inclined type cushioning block also has multiple different height sizes. In this way, the cushioning block 3 can be selected according to the situation of the box body part 1 to meet various needs.

[0060] In the embodiment, as a preferred design, the positioning base surface 22 is provided with a connecting structure for fixed installation of the cushioning block 3, the connecting structure is multiple and located at different positions of the positioning base surface 22, wherein the connecting structure comprises a connecting through hole 23 formed on the positioning base surface 22, the bottom of the cushioning block 3 is provided with a threaded hole, and the cushioning block 3 can be installed on the positioning base surface 22 through screwing, that is, the screw is screwed into the threaded hole of the bottom of the cushioning block 3 from the bottom of the quick-change supporting plate 2 through the connecting through hole 23, which facilitates the disassembly and assembly of the cushioning block 3. Of course, other suitable structures can also be used for the connecting structure.

[0061] In the embodiment, referring to Figure 1The quick-change tray 2 is a square plate with a flat upper surface forming a positioning base 22. The positioning base 22 of the quick-change tray 2 has multiple parallel and equidistant horizontal positioning lines and multiple parallel and equidistant vertical positioning lines. The horizontal positioning lines are along the left-right direction, and the vertical positioning lines are along the front-back direction. The horizontal and vertical positioning lines are perpendicular. Both the horizontal and vertical positioning lines are virtual reference lines. The connecting through holes 23 are located at the intersection of the vertical positioning lines, meaning the connecting through holes 23 are arranged in multiple rows and columns. Those on the same horizontal positioning line form a row, and those on the same vertical positioning line form a column. This method facilitates the positioning of the shim block 3 on the positioning base 22, allowing for quick installation in the appropriate location as needed. Furthermore, the quick-change tray 2 also has row numbers 24 corresponding to the horizontal positioning lines and column numbers 25 corresponding to the vertical positioning lines. See [link to relevant documentation]. Figure 2 Row number 24 uses letters A to E to mark the first to fifth rows respectively, and column number 25 uses numbers 1 to 19 to mark the first to nineteenth columns respectively. By using row number 24 and column number 25, the installation position of the shim block 3 can be quickly and easily confirmed, avoiding errors when the operator installs the shim block 3.

[0062] In this embodiment, the quick-change positioning device further includes a positioning mechanism 4, which can be detachably installed on the quick-change tray 2. The positioning mechanism 4 is used to install on one side of the quick-change tray 2 in the front-back direction and on one side in the left-right direction to position the box-type parts 1.

[0063] S2, Part clamping:

[0064] Select one or more surfaces on the box-type part 1 as the part positioning surface 11, and determine the support area on the part positioning surface 11; according to the number and position of the support points, select the corresponding number of shims 3 and fix them on the quick-change tray 2, and apply structural adhesive on the support plane 31; place the box-type part 1 on the shims 3, and attach and bond the support area to the support plane 31 of the shims 3.

[0065] In this step, when selecting a suitable surface as the positioning surface 11 on the box-type part 11, it is preferable to select the surface on the side of the box-type part 11 with lower machining requirements as the positioning surface 11. See [link to relevant documentation]. Figure 2 Depending on the specific structure of the box-type part 1, the part positioning surface 11 can be a single surface or include multiple surfaces. When the box-type part 1 is positioned and installed, the part positioning surface 11 can be parallel to or inclined to the positioning base surface 22 of the quick-change tray 2. According to the actual situation of the part positioning surface 11, a suitable shim 3 is selected, specifically including the following situations: (1) See Figure 7When the part positioning surface 11 is a whole plane and is suitable to keep horizontal with the positioning base surface 22 during installation, a plurality of plane type supporting blocks 3 with appropriate height are selected to support the part positioning surface 11: (2) see Figure 8 When the part positioning surface 11 is a whole plane and is suitable to keep horizontal with the positioning base surface 22 during installation, a plurality of plane type supporting blocks 3 with appropriate height are selected to support the part positioning surface 11: (2) see Figure 9 When the part positioning surface 11 is a whole plane and is suitable to keep horizontal with the positioning base surface 22 during installation, a plurality of plane type supporting blocks 3 with appropriate height are selected to support the part positioning surface 11: (2) see

[0066] When determining the supporting areas on the part positioning surface 11, the areas with high structural strength are preferred to be supported, and the number of the supporting areas is distributed as evenly as possible to ensure that the supporting blocks 3 can stably support the box type part 1. When determining the installation positions of the supporting blocks 3, the box type part 1 is placed in the middle of the quick-change supporting plate 2 at a proper position for preliminary positioning. In this embodiment, see Figure 3 The positioning mechanisms 4 are installed on the front side and the right side of the quick-change supporting plate 2. By adjusting the positioning mechanisms 4, the positioning mechanisms 4 are abutted against the front side and the right side of the box type part 1 to position the box type part 1 in the front-rear and left-right directions and limit the rotation of the box type part 1 in the horizontal direction. Then, according to the positions of the supporting areas, the supporting blocks 3 are installed on the connecting through holes 23 corresponding to the positions of the supporting areas on the positioning base surface 22, so that the supporting blocks 3 are located below the corresponding supporting areas. After the determination, the row index 24 and the column index 25 of the connecting through holes 23 are recorded to determine the installation positions of the supporting blocks 3. The supporting blocks 3 are fixed by screws passing through the connecting through holes 23 from the bottom of the quick-change supporting plate 2 and being screwed into the threaded holes in the bottom of the supporting blocks 3. The size of the quick-change supporting plate 2 is determined according to the size of the box type part 1. After the installation of the box type part 1, the box type part 1 can at most exceed the edge of the quick-change supporting plate 2 by 50 mm to ensure the stability after the installation.

[0067] After the installation of the supporting blocks 3, the supporting blocks 3 required by the box type part 1 and the row index 24 and the column index 25 of the installation positions of the supporting blocks 3 are recorded, and the positions of the positioning mechanisms 4 are recorded at this time. For the same box type part 1, the preliminary positioning is not required, and the supporting blocks 3 can be directly installed on the corresponding connecting through holes 23, and the positioning mechanisms 4 can be installed at the same positions, which is convenient for operation and can effectively improve the positioning and fixing efficiency of the box type part 1.

[0068] In the present application, the cushion block 3 and the box-shaped part 1 are made of steel material, and the structural adhesive refers to an adhesive with high strength (compression strength > 65 MPa, steel-steel tensile bonding strength > 30 MPa, shear strength > 18 MPa), capable of bearing a large load, resistant to aging, fatigue and corrosion, and stable in performance within the expected service life, suitable for bonding of structural parts bearing strong force. In the present embodiment, the components of the structural adhesive include methyl methacrylate, alpha-methyl acrylic acid, and 2,2'-[(4-methylphenyl) imino] bisethanol. Specifically, the structural adhesive of the glue type with the model number RK-1500 produced by WEICON in Germany is used, which can well fasten the box-shaped part 1 and the cushion block 3, and can bear a large impact force during subsequent part processing, without the problem of disconnection of the box-shaped part 1 and the cushion block 3.

[0069] After the static one-end time, the support area of the box-shaped part 1 is well bonded to the support plane 31 of the cushion block 3, the box-shaped part 1 is stably fixed on the cushion block 3, the positioning and fixing work is completed, and then the positioning mechanism 4 is detached from the quick-change support plate 2 to avoid the influence of the quick-change support plate 2 on subsequent processing.

[0070] S3, part processing:

[0071] The quick-change support plate 2 is positioned and fixed on the processing station, so that the box-shaped part 1 is well positioned and fixed on the processing station; the box-shaped part 1 is processed; after processing, the quick-change support plate 2 is detached from the processing station, and the box-shaped part 1 is integrally taken out from the processing station together with the quick-change support plate 2 and the cushion block 3.

[0072] In the present embodiment, preferably, a pin is arranged at the bottom of the quick-change support plate 2, and a clamping base 5 is arranged at the processing station of the machine tool, and the clamping base 5 is provided with a tensioning mechanism 51, and when the quick-change support plate 2 is installed, the pin is clamped into the tensioning mechanism 51, and the tensioning mechanism 51 is locked to clamp and fix the pin.

[0073] When the box-shaped part 1 is processed, the box-shaped part 1 can be processed in five directions except for the side surface facing the quick-change support plate 2. Since there is no traditional pressing plate structure, the cutter will not interfere with the pressing plate during processing, and the cushion block 3 raises the box-shaped part 1 to a certain height, so that the cutter will not interfere with the structures such as the quick-change support plate 2, the clamping base 5 and the machine tool table below the box-shaped part 1 during processing of the lower part of the box-shaped part 1, facilitating processing, and the programming of the processing program can be further simplified, improving the processing efficiency on the machine tool.

[0074] In the step, the machining can be performed on one machine tool or on multiple machine tools, and when switching between different machine tools, only positioning and installation through the quick-change support plate 2 are needed, which is fast and convenient, and the box-shaped part 1 does not need to be clamped and positioned every time, thereby greatly reducing the clamping time.

[0075] S4, part disassembly: injecting a sol agent into the groove 32 from the notch at the side wall of the heightening block 3, dissolving the structural glue after the sol agent, and separating the box-shaped part 1 from the heightening block 3. Preferably, the bolts at the bottom of the quick-change support plate 2 are first disassembled, the heightening block 3 is separated from the quick-change support plate 2, and then the sol operation is performed, which is more convenient, and meanwhile the support plate 2 can be immediately used for machining of the next part, thereby improving the utilization efficiency. After the sol agent is injected into the groove 32, it can penetrate between the support plane 31 and the box-shaped part 1 under pressure, gradually dissolving the structural glue, and after a period of standing, the heightening block 3 and the box-shaped part can be completely separated. In this embodiment, the composition of the sol agent includes acetone, butyl acetate, 1-methoxy-2-propanol, diethylene glycol-butyl ether, and cyclohexanone, and specifically, a sol agent with a model number of 699 produced by the Dynasolve company in the United States can be used, which can well dissolve the structural glue of the RK-1500 model.

[0076] In this embodiment, the groove 32 on the support plane 31 of the heightening block 3 is provided with multiple channels, and all pass through the axis of the cylindrical heightening block 3, meet at the axis of the heightening block 3, and the interval angles between the connected grooves 32 are equal. The use of multiple grooves 32 can better inject the sol agent and facilitate the sol.

[0077] In this embodiment, preferably, while the sol is being performed, machine tool coolant is sprayed into the bonding position of the heightening block 3 and the box-shaped part 1, and the machine tool coolant is continuously sprayed at a certain pressure, which can carry away the dissolved structural glue, facilitate the further injection of the sol agent into the gap between the support plane 31 and the box-shaped part 1 for sol.

[0078] After the heightening block 3 is separated from the box-shaped part 1, the machining of the box-shaped part 1 is completed, and the heightening block 3 can continue to be used for machining of the next box-shaped part 1. Since the gluing and fixing of the box-shaped part 1 to the quick-change positioning device and the separation are both completed on the machine tool line, the machine tool occupation time is reduced, the effective use efficiency of the machine tool is improved, the clamping and positioning time is greatly reduced, and the machining efficiency and quality of the box are improved.

[0079] In this embodiment, as a preferred design, refer to Figure 3 and Figure 4The front side or the rear side of the quick-change supporting plate 2 of the quick-change positioning device is provided with a plurality of positioning connecting holes 21, and the left side or the right side of the quick-change supporting plate 2 is provided with a plurality of positioning connecting holes 21; the positioning mechanism 4 comprises a bracket 41, a positioning blocking column 42 and a connecting bolt 43; a strip-shaped through hole is arranged in the bracket 41 along the length direction of the bracket 41; the connecting bolt 43 penetrates through the strip-shaped through hole and is screwed into the positioning connecting hole 21; one end of the bracket 41 is fixed on the quick-change supporting plate 2; the positioning blocking column 42 is installed on the other end of the bracket 41 through a bolt; and the positioning blocking column 42 is used for abutting against the part. Figure 1 When the length of one bracket 41 is not enough, two blocking plates can be fixedly connected through a bolt and a strip-shaped through hole, so that the length of the bracket 41 is prolonged, and the use requirement in different situations is met.

[0080] It can be known from the above that the machining method has the following technical effects:

[0081] 1. The box-shaped part 1 only needs to be clamped and fixed once on the quick-change positioning device, can be installed on the machine tool to complete most of the machining features, is fixed through the adhesive mode, does not need a pressing plate and other structures, can avoid the tool interference problem in the machining process, enables the part to be perfectly machined in a free state, and greatly improves the machining quality and machining efficiency.

[0082] 2. The clamping and dismounting of the box-shaped part 1 are both installed outside the machine tool, do not occupy the machine tool time, and improve the effective utilization rate of the machine tool.

[0083] 3. The adhesive fixing mode replaces the pressing plate, simplifies the clamping and positioning work and operation, avoids the compression deformation of the part, and enables the fixing and dismounting work of the box-shaped part 1 to be flexible and convenient and the operation to be simple.

[0084] 5. The use range is wide, can be used for the machining of most box-shaped parts 1, has good universality, does not need to design different clamping tooling for different parts, is especially suitable for the box-shaped parts 1 in the discrete manufacturing industry with small batch and multiple varieties, reduces the design and manufacturing of the clamping tooling, and can reduce the cost.

[0085] 6. It reduces the difficulty of clamping, fixing and machining box-type parts 1, and lowers the skill level requirements for operators.

[0086] 7. The quick-change positioning device enables rapid switching between different machine tools, facilitating the automated processing of various box-type parts, serving as an important link in the intelligent manufacturing of box-type parts.

[0087] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
