Technical Field

[0001] This application relates to the field of tooling fixtures, and particularly to a tooling fixture and processing technology for a numerical control machine tool. Background Art

[0002] At present, hardware parts play an important role in industrial production, and their processing accuracy and efficiency directly affect the quality and production cost of products. With the development of the manufacturing industry, the processing requirements for hardware parts are getting higher and higher, especially in hole opening, slotting, and various precision processing steps, the requirements for accuracy and efficiency are particularly strict.

[0003] In the processing of hardware parts in related technologies, numerical control machine tools have become indispensable equipment. In order to achieve multi-angle processing of hardware parts, a dividing machine is usually set in the numerical control machine tool, and the hardware parts are fixed to the dividing machine through a tooling fixture. The dividing machine can drive the tooling fixture to rotate at different angles, so as to achieve multi-angle processing of the hardware parts.

[0004] Traditional tooling fixtures have limitations in adapting to the complex shapes of hardware parts. They often cannot closely fit the surface of the hardware parts, resulting in easy shaking or displacement of the hardware parts during the processing, thus affecting the processing accuracy. In addition, the clamping mechanism of traditional tooling fixtures may be too complex or not flexible enough to meet the processing requirements of hardware parts with different shapes and sizes. Summary of the Invention

[0005] In order to overcome the deficiencies of traditional tooling fixtures in adapting to the complex shapes of hardware parts and clamping flexibility, and improve the processing accuracy and efficiency of hardware parts, this application provides a tooling fixture and processing technology for a numerical control machine tool.

[0006] The tooling fixture and processing technology for a numerical control machine tool provided by this application adopt the following technical solutions: In the first aspect, this application discloses a tooling fixture for a numerical control machine tool, including a mounting block, a positioning mechanism, and a clamping mechanism; the mounting block is used for fixedly connecting with the turntable of the dividing machine, and the dividing machine is arranged in the numerical control machine tool and used for driving the mounting block to rotate; the positioning mechanism is arranged on the mounting block and is used for positioning the hardware parts; the clamping mechanism is arranged on the mounting block and is used for clamping and fixing the hardware parts.

[0007] By adopting the above technical solution, with the stable connection between the mounting block and the indexing machine turntable, the mounting block and the hardware parts thereon can be rotated to the required processing angle by the drive of the indexing machine. The positioning mechanism accurately positions the hardware parts, effectively preventing shaking or displacement during the processing, while the clamping mechanism, with its high flexibility and adaptability, closely fits various complex-shaped hardware parts to ensure stable clamping. This tooling fixture and processing technology not only significantly improve the processing accuracy and efficiency of the hardware parts, but also overcome the limitations of traditional tooling fixtures in adapting to the complex shapes of hardware parts and clamping flexibility, providing strong technical support for the high-quality development of the manufacturing industry, reducing production costs, and improving product quality.

[0008] Optionally, the positioning mechanism includes a plurality of positioning rods, one end of each positioning rod is fixedly connected to the mounting block, and the other end of each positioning rod is provided with a positioning portion for positioning the hardware parts.

[0009] By adopting the above technical solution, the positioning mechanism uses a plurality of carefully arranged positioning rods. One end of these positioning rods is firmly connected to the mounting block, and the other end is cleverly equipped with a positioning portion specifically used to accurately lock the position of the hardware parts. This not only simplifies the positioning process, but also greatly improves the accuracy and stability of positioning, ensuring that the hardware parts can always maintain the correct position during the rotary processing, and avoiding processing errors caused by improper positioning. In addition, the setting of a plurality of positioning rods can be flexibly adjusted according to the shapes and sizes of different hardware parts, further broadening the applicable range of the tooling fixture, making it show excellent processing capabilities and efficiency when dealing with various complex-shaped hardware parts.

[0010] Optionally, the positioning portion is a positioning flange or a positioning groove.

[0011] By adopting the above technical solution, one end of the positioning rod is firmly installed on the mounting block, and the other end is cleverly equipped with a positioning flange or a positioning groove. These positioning portions can accurately and firmly lock the position of the hardware parts according to the specific shape and processing requirements of the hardware parts. The positioning flange is suitable for matching with the outer edge of the hardware part to provide stable support and positioning; while the positioning groove can perfectly fit the protruding part of the hardware part to achieve close fitting and positioning. This not only significantly improves the accuracy of positioning, but also ensures the stable position of the hardware parts during the processing.

[0012] Optionally, the positioning mechanism further includes at least one positioning block fixedly connected to the mounting block.

[0013] By adopting the above technical solutions, the positioning mechanism not only includes multiple positioning rods, one end of which is firmly installed on the mounting block and the other end is equipped with a positioning flange or a positioning groove, achieving precise positioning of the hardware; but also adds at least one positioning block, which is firmly connected to the mounting block, further enhancing the support and fixation of the fixture to the hardware. The positioning blocks can be flexibly arranged according to the shape of the hardware and the processing requirements, and work together with the positioning rods to jointly construct a comprehensive and stable positioning system. This not only significantly improves the accuracy and stability of positioning, ensuring that the hardware does not move during the processing, but also further broadens the applicable range of the fixture, enabling it to easily handle the processing requirements of various complex-shaped and sized hardware.

[0014] Optionally, a positioning groove is formed on the mounting block, and the outer side wall of the positioning block abuts against the inner side wall of the positioning groove.

[0015] By adopting the above technical solutions, the formation of the positioning groove not only provides an accurate installation reference for the positioning block, ensuring the accurate position of the positioning block on the mounting block, but also effectively prevents the positioning block from loosening or displacing during the processing through the close fit between the positioning block and the inner side wall of the positioning groove, thereby greatly enhancing the overall stability and durability of the fixture.

[0016] Optionally, a plurality of spaced threaded holes are formed in the positioning groove, a bolt is passed through the positioning block, and the bolt is in threaded cooperation with one of the threaded holes.

[0017] By adopting the above technical solutions, by carefully forming a plurality of spaced threaded holes in the positioning groove and threading the bolt on the positioning block with one of the threaded holes, the fixture of the present application further strengthens the stability and flexibility of its positioning mechanism. This not only provides multiple installation options for the positioning block, enabling the positioning block to accurately adjust its position according to the shape of the hardware and the processing requirements to ensure that the hardware is firmly and accurately positioned; but also realizes the firm connection between the positioning block and the mounting block through the tight threaded cooperation between the bolt and the threaded hole, effectively preventing the positioning block from loosening or displacing during the processing, thereby greatly improving the overall stability and processing accuracy of the fixture. In addition, the plurality of spaced threaded holes also enable the fixture to adapt to the processing requirements of different sizes and shapes of hardware, enhancing its versatility and adaptability.

[0018] Optionally, a through avoidance groove is formed on the mounting block.

[0019] By adopting the above technical solution, through the ingenious opening of a through avoidance groove on the mounting block, the fixture of the present application not only maintains a compact structure but also significantly improves its flexibility and adaptability during the processing of hardware parts. The through avoidance groove not only provides sufficient space for the installation and disassembly of hardware parts, enabling the fixture to easily handle various shapes and sizes of hardware parts, reducing the operation difficulty and improving the processing efficiency; moreover, the existence of the avoidance groove effectively avoids the interference problem of the fixture on the mounting block, ensuring that the positioning mechanism and the clamping mechanism can work smoothly, further improving the stability and processing accuracy of the fixture. In addition, the opening of the avoidance groove also reduces the overall weight of the mounting block, making the fixture run more smoothly on the numerical control machine tool, reducing energy consumption and noise.

[0020] Optionally, the clamping mechanism includes a driving assembly and a plurality of clamping assemblies. Each clamping assembly includes a fixed rod, a driving rod, and a clamping rod. The end of the fixed rod is fixedly connected to the mounting block, and one end of the clamping rod is rotatably connected to the fixed rod; the driving rod passes through the mounting block, and the driving rod is in sliding fit with the mounting block; one end of the driving rod is rotatably connected to the middle of the clamping rod, and the other end of the clamping rod is used for clamping the hardware part.

[0021] By adopting the above technical solution, when the driving assembly is started, the driving rod slides under the action of the driving force. Through its rotational connection with the clamping rod, it drives the other end of the clamping rod to precisely clamp or release the hardware part. This not only significantly improves the clamping accuracy and stability, ensuring that the position of the hardware part remains unchanged during the processing, but also greatly enhances the adaptability of the fixture to hardware parts of different shapes and sizes. In addition, the coordinated work of multiple clamping assemblies enables the fixture to easily handle various complex processing requirements, further improving the processing efficiency and flexibility.

[0022] Optionally, the driving assembly includes a cylinder and a linkage block. One ends of the plurality of driving rods passing through the mounting block are all fixedly connected to the linkage block; the cylinder is arranged on the linkage block, the piston rod of the cylinder passes through the linkage block and is in sliding fit with the linkage block, and the end of the piston rod is fixedly connected to the mounting block.

[0023] By adopting the above technical solution, when the cylinder is started, the piston rod reciprocates under the driving force of the cylinder, and drives all the driving rods to slide synchronously through the linkage block. This not only ensures that multiple clamping components can clamp or release the hardware synchronously and precisely, greatly improving the clamping efficiency and stability, but also can flexibly control the clamping force by adjusting the driving force of the cylinder to meet the processing requirements of hardware with different materials and shapes. In addition, the close cooperation between the cylinder and the linkage block makes the structure of the driving component more compact and stable, further enhancing the overall performance and durability of the tooling fixture.

[0024] In a second aspect, the present application also discloses a processing technology using any one of the above tooling fixtures for a numerical control machine tool, including the following steps: Step 1: Fix the mounting block of the tooling fixture to the indexing turntable in the numerical control machine tool to ensure firm installation; Step 2: According to the shape and size of the hardware to be processed, adjust the positions of the positioning rods and / or positioning blocks in the positioning mechanism to ensure that the positioning flanges or positioning grooves of the positioning parts are precisely matched with the corresponding parts of the hardware; Step 3: Place the hardware on the positioning mechanism, and use the precise guidance of the positioning part to ensure that the hardware is in the correct processing position; Step 4: Start the driving component of the clamping mechanism, such as a cylinder. The expansion and contraction of the piston rod of the cylinder drives the linkage block to move, and then drives multiple driving rods to slide on the mounting block. The movement of the driving rods causes the clamping rods to rotate around the fixed rods until the other ends of the clamping rods tightly clamp the hardware, ensuring that the hardware remains stable during the processing; Step 5: After the hardware is accurately positioned and firmly clamped, start the numerical control machine tool for processing operations; Step 6: After the processing is completed, release the clamping force by reverse operation of the driving component, remove the hardware, and prepare for the next round of processing.

[0025] By adopting the above technical solution, the installation block of the tooling fixture is firmly connected to the indexing turntable in the CNC machine tool, ensuring the stability of the machining process. Subsequently, according to the shape and size of the hardware parts to be machined, the positions of the positioning rods and / or positioning blocks in the positioning mechanism are flexibly adjusted. By using the precise matching of the positioning flange or positioning groove with the hardware parts, the precise positioning of the hardware parts is achieved. Then, start the driving component of the clamping mechanism, such as a cylinder. Through the telescopic movement of its piston rod, the linkage block and multiple driving rods are driven to move, prompting the clamping rods to tightly clamp the hardware parts, ensuring the stability of the hardware parts during the machining process. After the hardware parts are accurately positioned and firmly clamped, the CNC machine tool can be started for machining operations. After the machining is completed, the clamping force can be easily released by operating the driving component in reverse, and the hardware parts can be removed to prepare for the next round of machining. This machining process not only significantly improves the machining accuracy and efficiency of the hardware parts, but also greatly enhances the adaptability of the tooling fixture to hardware parts of different shapes and sizes.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The positioning rods and positioning blocks in the positioning mechanism can be flexibly adjusted according to the shape and size of the hardware parts, ensuring that the hardware parts always maintain the correct position during the machining process. At the same time, the clamping mechanism drives multiple clamping components to work synchronously through a cylinder, which can tightly clamp the hardware parts and prevent them from shaking or displacing during the machining process, thus significantly improving the machining accuracy and stability; 2. The tooling fixture of the present application has wide applicability and high flexibility. The positioning part in the positioning mechanism can adopt various forms such as positioning flanges or positioning grooves to adapt to hardware parts of different shapes and sizes. The clamping mechanism can also be flexibly adjusted according to the characteristics of different hardware parts to ensure the stability and accuracy of clamping. Therefore, the tooling fixture of the present application can easily meet various complex machining requirements, improving the machining efficiency and flexibility; 3. Using the tooling fixture of the present application for machining hardware parts can significantly improve the machining efficiency and reduce the production cost. The precise positioning and firm clamping functions of the tooling fixture reduce the errors and scrap rate during the machining process, improving the product quality. At the same time, the flexibility and adaptability of the tooling fixture make the machining process more efficient, reducing manual intervention and downtime, thus reducing the production cost. In addition, the compact and stable structure of the tooling fixture makes its operation on the CNC machine tool more stable, reducing energy consumption and noise, and further improving the machining efficiency and economic benefits.

[0031] The following further elaborates on the present application in conjunction with the attached Figures 1-3 for a more detailed description.

[0032] The terms used in the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. Unless otherwise defined, the technical terms or scientific terms used in the present application should have the ordinary meaning understood by those skilled in the art within the field to which the present application belongs. The "first", "second" and similar terms used in the present application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0033] Embodiment 1 A tooling fixture for a numerical control machine tool provided in an embodiment of the present application, referring to Figure 1 and Figure 2 , the tooling fixture for a numerical control machine tool includes a mounting block 1, a positioning mechanism 2 and a clamping mechanism 3. The mounting block 1 is used for fixedly connecting with the turntable 41 of the dividing machine 4, and the dividing machine 4 is arranged in the numerical control machine tool and is used for driving the turntable 41 to rotate, thereby driving the mounting block 1 to rotate. Two reinforcing blocks 5 are also fixedly arranged on the surface of the mounting block 1, and both of the two reinforcing blocks 5 are fixedly connected with the turntable 41 of the dividing machine 4, increasing the firmness of the mounting block 1 fixed on the turntable 41.

[0034] Referring to Figure 1 , the positioning mechanism 2 is arranged on the mounting block 1 and is used for positioning the hardware parts; the clamping mechanism 3 is arranged on the mounting block 1 and is used for clamping and fixing the hardware parts. The driving function of the dividing machine 4 can be utilized to realize the multi-angle rotation of the mounting block 1 and the hardware parts thereon, obtaining different processing angles, and multiple surfaces can be processed at one time, improving the processing efficiency and accuracy.

[0035] Referring to Figure 1, Specifically, the mounting block 1 is made of high-strength aluminum alloy material, which has good rigidity and corrosion resistance. The mounting block 1 is used to be fixedly connected to the turntable 41 of the indexing machine 4 through bolts. This not only ensures the stability of the mounting block 1 but also facilitates installation and disassembly.

[0036] Refer to Figure 1 , The positioning mechanism 2 includes a plurality of positioning rods 21. One end of these positioning rods 21 is fixedly connected to the mounting block 1, and the other end is provided with a positioning portion 22. The positioning portion 22 can be a positioning flange or a positioning groove, depending on the shape and processing requirements of the hardware. For example, for hardware with a relatively flat outer contour, a positioning flange can be selected to provide stable support; while for hardware with a protruding structure inside, a positioning groove can be selected for tight fitting. The positioning rods 21 themselves can be made of stainless steel material to increase their wear resistance and service life. Another option is to use carbon steel material, which also has high strength and wear resistance.

[0037] Refer to Figure 1 , In addition, the positioning mechanism 2 further includes at least one positioning block 23. A positioning groove 11 is formed on the mounting block 1. The outer side wall of the positioning block 23 abuts against the inner side wall of the positioning groove 11, and the positioning block 23 is fixedly connected to the mounting block 1. The positioning groove 11 ensures the accurate position of the positioning block 23 on the mounting block 1. A plurality of spaced threaded holes 12 are also formed in the positioning groove 11. Bolts are passed through the positioning block 23, and the bolts are threadedly engaged with one of the threaded holes 12. In this way, the position of the positioning block 23 can be finely adjusted by adjusting the position of the bolts to adapt to hardware of different shapes and sizes. This not only increases the flexibility of positioning but also improves the accuracy of positioning. Another alternative is to provide an elastic pressing plate on the positioning block 23 to slightly press the hardware through elastic force to enhance the positioning effect.

[0038] Refer to Figure 1 , A through relief groove 13 is also formed on the mounting block 1. This not only provides sufficient space for the installation and disassembly of the hardware but also effectively avoids the interference problem of the tooling fixture on the mounting block 1, ensuring the smooth operation of the positioning mechanism 2 and the clamping mechanism 3. The relief groove 13 also helps to reduce the overall weight of the mounting block 1, making the operation of the tooling fixture on the numerically controlled machine tool more stable, reducing energy consumption and noise. The depth and width of the relief groove 13 can be adjusted according to actual needs to adapt to hardware of different thicknesses and shapes.

[0039] Refer to Figure 1 and Figure 3, the clamping mechanism 3 includes a driving component 31 and multiple clamping components 32. Each clamping component 32 includes a fixed rod 321, a driving rod 322, and a clamping rod 323. The end of the fixed rod 321 is fixedly connected to the mounting block 1, and one end of the clamping rod 323 is rotatably connected to the fixed rod 321. The driving rod 322 passes through the mounting block 1 and is in sliding fit with the mounting block 1. One end of the driving rod 322 is rotatably connected to the middle of the clamping rod 323, and the other end of the clamping rod 323 is used to clamp the hardware. When the driving component 31 is activated, the driving rod 322 slides under the action of the driving force. Through its rotational connection with the clamping rod 323, it drives the other end of the clamping rod 323 to accurately clamp or release the hardware. This not only significantly improves the clamping accuracy and stability but also can flexibly handle hardware of different shapes and sizes. The fixed rod 321 and the clamping rod 323 can be made of high-strength alloy steel materials to increase their rigidity and durability. Another option is to use carbon fiber composite materials to reduce self-weight and improve fatigue resistance.

[0040] Continue to refer to Figure 1 and Figure 3 , the driving component 31 includes a cylinder 311 and a linkage block 312. One ends of multiple driving rods 322 passing through the mounting block 1 are all fixedly connected to the linkage block 312. The cylinder 311 is arranged on the linkage block 312. The piston rod of the cylinder 311 passes through the linkage block 312 and is in sliding fit with the linkage block 312. The end of the piston rod is fixedly connected to the mounting block 1. When the cylinder 311 is activated, the piston rod reciprocates under the driving force of the cylinder 311 and drives all the driving rods 322 to slide synchronously through the linkage block 312. This not only ensures that multiple clamping components 32 can clamp or release the hardware synchronously and accurately, greatly improving the clamping efficiency and stability, but also flexibly controls the magnitude of the clamping force through the driving force adjustment of the cylinder 311 to meet the processing requirements of hardware of different materials and shapes. The cylinder 311 can be a high-pressure cylinder 311 to provide greater driving force, suitable for clamping heavy hardware. Another option is to use a cylinder 311 controlled by a solenoid valve to achieve precise control through electrical signals, suitable for occasions that require frequent switching of the clamping state.

[0041] The implementation principle of this embodiment is as follows: By firmly connecting the mounting block 1 of the tooling fixture to the turntable 41 of the indexing machine 4 inside the CNC machine tool, the stability of the machining process is ensured. Subsequently, according to the shape and size of the hardware parts to be machined, the positions of the positioning rods 21 and / or positioning blocks 23 in the positioning mechanism 2 are flexibly adjusted. By using the precise matching of the positioning flanges or positioning grooves with the hardware parts, the precise positioning of the hardware parts is achieved. Then, the driving component 31 of the clamping mechanism 3, such as the cylinder 311, is started. Through the telescopic movement of its piston rod, the movement of the linkage block 312 and multiple driving rods 322 is driven, prompting the clamping rod 323 to tightly clamp the hardware parts, ensuring the stability of the hardware parts during the machining process. After the hardware parts are precisely positioned and firmly clamped, the CNC machine tool can be started for machining operations. After machining is completed, the clamping force can be easily released by operating the driving component 31 in reverse, and the hardware parts are removed to prepare for the next round of machining. This tooling fixture and machining process not only significantly improve the machining accuracy and efficiency of the hardware parts, but also greatly enhance the adaptability of the tooling fixture to hardware parts of different shapes and sizes.

[0042] Embodiment 2 Referring to Figure 1 , the difference between this embodiment and the above embodiment is that: An adjustable positioning pin is introduced in the positioning mechanism 2 to further enhance the flexibility and accuracy of positioning. Specifically, in addition to the original positioning rods 21 and positioning blocks 23, multiple adjustable positioning pins are added to the mounting block 1. These positioning pins can slide freely within the guide rails on the mounting block 1 and are fixed at the required positions through locking nuts. Allowing users to flexibly adjust the positions of the positioning pins according to the actual shape and size of the hardware parts, thereby achieving more precise positioning. The adjustable positioning pins can be made of copper alloy material, which has good wear resistance and low friction coefficient and is suitable for high-frequency use. Another option is to use stainless steel material to increase its corrosion resistance and lifespan.

[0043] In addition, the clamping rods 323 in the clamping mechanism 3 can also adopt different materials and structures. For example, for application scenarios that require higher strength, carbon fiber composite materials can be selected to make the clamping rods 323 to reduce self-weight and improve fatigue resistance. Another option is to use titanium alloy material, which has the characteristics of light weight, high strength and good corrosion resistance and is suitable for long-term use. The contact surface of the clamping rod 323 can be coated with a layer of polyurethane coating to increase friction and prevent the hardware parts from sliding during the machining process.

[0044] The implementation principle of this embodiment is as follows: By introducing adjustable positioning pins, the flexibility and accuracy of positioning are further improved, enabling the tooling fixture to better adapt to hardware parts of different shapes and sizes. At the same time, by optimizing the material and structure of the clamping rod 323, the stability and reliability of clamping are enhanced, thus significantly improving the comprehensive performance of the entire system. It not only improves the machining accuracy and efficiency but also extends the service life of the tooling fixture and reduces the maintenance cost.

[0045] Embodiment 3 Referring to Figure 1 , the main difference between this embodiment and the above-mentioned embodiments lies in that an automatic detection and feedback mechanism is added to the clamping mechanism 3 to monitor the clamping state in real time and make dynamic adjustments. Specifically, pressure sensors are installed at the ends of the clamping rods 323, which can monitor the changes in the clamping force in real time. When the clamping force exceeds the preset range, the control system will automatically adjust the pressure of the cylinder 311 to maintain an appropriate clamping force. This can not only prevent the deformation of the hardware parts caused by excessive clamping but also ensure that the clamping force is always in the best state, thereby improving the machining quality and efficiency. Piezoelectric sensors with high sensitivity can be selected as the pressure sensors, which have a fast response speed and high measurement accuracy. Another option is to use photoelectric sensors, which indirectly measure the clamping force through the change of light signals and are suitable for transparent or semi-transparent hardware parts.

[0046] In addition, to avoid the wear of the clamping rod 323 after long-term use, a wear-resistant coating can be added to the contact surface of the clamping rod 323. Commonly used wear-resistant coating materials include ceramic coatings and hard chromium coatings, which have extremely high hardness and wear resistance and can significantly extend the service life of the clamping rod 323. Another option is to use silicon nitride coatings, which have higher hardness and better high-temperature resistance and are suitable for applications in high-temperature environments.

[0047] The implementation principle of this embodiment is as follows: By adding an automatic detection and feedback mechanism to monitor and adjust the clamping force in real time, ensuring that the clamping force is always in the best state, thereby improving the machining quality and efficiency. At the same time, by performing wear-resistant treatment on the contact surface of the clamping rod 323, the service life of the clamping rod 323 is extended and the maintenance cost is reduced. It not only improves the reliability and stability of the tooling fixture but also greatly enhances the user experience.

[0048] Embodiment 4 Referring to Figure 1, The main difference between this embodiment and the above - mentioned embodiments is that a vision - assisted system is introduced in the positioning mechanism 2 to further improve the accuracy and convenience of positioning. Specifically, a camera and an image - processing module are arranged on the mounting block 1. The camera can capture images of the hardware parts and analyze them through the image - processing module to generate positioning data. These positioning data can be directly transmitted to the control system of the numerical control machine tool to help the user quickly and accurately adjust the positions of the positioning rod 21 and the positioning block 23, thus realizing efficient automatic positioning. The camera can be a high - definition CMOS camera with high resolution and good imaging quality. The image - processing module can be integrated into the existing control system of the numerical control machine tool without additional hardware configuration.

[0049] In addition, to further improve the clamping stability, anti - slip pads can be installed at the front end of the clamping rod 323. These anti - slip pads can be made of rubber or other materials with a high coefficient of friction, which helps to increase the frictional force between the clamping rod 323 and the hardware part and prevent the hardware part from sliding during the processing. The anti - slip pads can be replaced regularly to ensure that they always maintain a good anti - slip effect. Another option is to use silicone pads, which have better flexibility and adhesiveness and are suitable for hardware parts with irregular shapes.

[0050] The implementation principle of this embodiment is as follows: By introducing the vision - assisted system, real - time automatic positioning is achieved, greatly improving the accuracy and convenience of positioning. At the same time, by installing anti - slip pads at the front end of the clamping rod 323, the clamping stability is further improved, ensuring that the hardware part does not slide during the processing. This not only improves the processing quality and efficiency but also simplifies the operation process and reduces the risk of human error.

[0051] Embodiment 5 This embodiment relates to a processing technology using the tooling fixture of any one of the foregoing embodiments, including the following steps: Step 1: Fix the mounting block 1 of the tooling fixture to the turntable 41 of the indexing machine 4 inside the numerical control machine tool to ensure firm installation; Step 2: According to the shape and size of the hardware part to be processed, adjust the positions of the positioning rod 21 and / or the positioning block 23 in the positioning mechanism 2 to ensure that the positioning flange or positioning groove of the positioning part 22 precisely matches the corresponding part of the hardware part. When necessary, fine - tune through the threaded holes 12 and bolts to achieve the best positioning effect; Step 3: Place the hardware part on the positioning mechanism 2 and use the precise guidance of the positioning part 22 to ensure that the hardware part is in the correct processing position; Step Four: Start the driving component 31 of the clamping mechanism 3, such as the cylinder 311. The telescopic movement of the piston rod of the cylinder 311 drives the linkage block 312 to move, thereby driving a plurality of driving rods 322 to slide on the mounting block 1. The movement of the driving rod 322 causes the clamping rod 323 to rotate around the fixed rod 321 until the other end of the clamping rod 323 tightly clamps the hardware part, ensuring the stable immobility of the hardware part during the processing; Step Five: After the hardware part is accurately positioned and firmly clamped, start the numerical control machine tool for processing operations; Step Six: After the processing is completed, release the clamping force by reverse operation of the driving component 31, remove the hardware part, and prepare for the next round of processing.

[0052] The implementation principle of this embodiment is as follows: By firmly connecting the mounting block 1 of the fixture to the turntable 41 of the indexing machine 4 in the numerical control machine tool, the stability of the processing process is ensured. Subsequently, according to the shape and size of the hardware part to be processed, flexibly adjust the positions of the positioning rods 21 and / or positioning blocks 23 in the positioning mechanism 2, and utilize the precise matching of the positioning flange or positioning groove with the hardware part to achieve the accurate positioning of the hardware part. Then, start the driving component 31 of the clamping mechanism 3, such as the cylinder 311. Through the telescopic movement of its piston rod, drive the movement of the linkage block 312 and a plurality of driving rods 322, so as to make the clamping rod 323 tightly clamp the hardware part, ensuring the stable immobility of the hardware part during the processing. After the hardware part is accurately positioned and firmly clamped, the numerical control machine tool can be started for processing operations. After the processing is completed, release the clamping force easily by reverse operation of the driving component 31, remove the hardware part, and prepare for the next round of processing. This processing technology not only significantly improves the precision and efficiency of hardware part processing, but also greatly enhances the adaptability of the fixture to hardware parts of different shapes and sizes.

[0053] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
