Description

Technical Field

[0001] This invention relates to the field of milling technology, and in particular to a reinforced milling device for CNC lathes. Background Technology

[0002] Currently, in the field of mechanical manufacturing, milling, as a key machining method that uses milling cutters as the core cutting tool to cut the surface of objects, is widely used in the production of various parts due to its high efficiency and precision. A wide variety of milling machines are available, including horizontal milling machines, vertical milling machines, gantry milling machines, profile milling machines, universal milling machines, and lever milling machines. Appropriate equipment can be selected to complete the machining operation according to different processing requirements and workpiece characteristics. With the continuous development and popularization of CNC technology, CNC lathes, due to their higher machining accuracy and automation, occupy an increasingly important position in modern machining. When machining objects on a lathe, the milling device, as a core functional component, directly affects the final machining quality and production efficiency. In practical machining applications, existing reinforced milling devices typically employ a working mode where the workpiece is fixed on the lathe, and the milling mechanism is used to cut the workpiece. However, over long-term use, this type of device has gradually revealed a series of problems affecting machining results and operational convenience. On the one hand, a large amount of particulate debris is inevitably generated during milling. If this debris is not cleaned up in a timely and effective manner, it can easily adhere to the workpiece surface or fixture, affecting subsequent machining accuracy and potentially interfering with the normal operation of the milling mechanism. Existing devices generally lack convenient and efficient debris flushing structures, making debris cleaning difficult and increasing the workload of operators. On the other hand, the position of the milling mechanism in existing milling devices is mostly relatively fixed, allowing only simple adjustments within a limited range. It is difficult to flexibly adjust the position according to the multi-angle machining requirements of complex workpieces, greatly limiting the applicability of the device and failing to meet diverse machining scenarios.

[0003] To address the issues of fixed position and inconvenient adjustment of the milling mechanism, Chinese Patent No. CN217096576U discloses a reinforced milling device for a CNC lathe. This device mainly includes a lathe and a milling mechanism mounted on the upper part of the lathe. The milling mechanism consists of a mounting frame, a guide groove, a second lead screw, a second threaded block, a housing, and a cutting tool. The guide groove is located on the side wall of the mounting frame. The second lead screw is installed inside the guide groove, with one end penetrating the mounting frame and connected to the output end of an external motor. The second threaded block is threaded onto the outside of the second lead screw. The housing is mounted on one side of the second threaded block, and the cutting tool is located on the other side of the housing. Its working principle involves turning on the motor to drive the second lead screw to rotate. With the cooperation of the second threaded block, the second threaded block moves along the guide groove, thereby causing the housing and the cutting tool to move synchronously, achieving adjustment of the cutting tool position. This allows for better processing of shaft-type workpieces and, to a certain extent, improves the problem of fixed position of the milling mechanism.

[0004] However, a deeper analysis of the specific application process of this patented device reveals significant defects and deficiencies in its overall structural design, making it difficult to fully meet the demands for high efficiency and flexibility in actual processing. Firstly, the clamping structure is overly simplistic. After the workpiece is fixed, the clamping structure cannot achieve a flipping adjustment function. During each milling operation, the generated chips easily adhere to the fixture surface. Because the fixture cannot be flipped, the chips cannot be smoothly discharged through the flipping action. The accumulation of large amounts of chips not only affects the clamping stability of the workpiece but may also scratch the workpiece surface during subsequent processing, reducing processing quality. Secondly, the fixture cannot... The flipping mechanism makes it difficult to flexibly adjust the milling angle of the clamped product. For complex workpieces that require multi-faceted and multi-angle machining, operators need to frequently disassemble and re-clamp the workpiece, which not only increases the number of operation steps and time costs, but may also cause positioning errors due to repeated clamping, further affecting the machining accuracy. In addition, if too much debris accumulates when the fixture cannot be flipped, it is easy for the fixture to tilt when clamping the workpiece, which seriously affects the positioning accuracy of the workpiece and thus causes machining deviations. It can be seen that there is still a lot of room for improvement in the practical application of this device, and its structure needs to be optimized to improve the overall performance and practicality of the device.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Firstly, in this invention, during the application of this technical solution, by setting up a clamping assembly and a first adjustment mechanism and a second adjustment mechanism, it is possible to first use the clamping assembly to stably clamp workpieces of different specifications during use. Specifically, the sixth motor drives the third lead screw to rotate, causing the sliding block and clamping arm to move, so that the clamping plate closely fits the workpiece, adapting to various workpiece sizes. Then, the first motor of the first adjustment mechanism drives the first lead screw, causing the first slider and the milling machine to move laterally, adjusting the lateral position of the milling cutter. At the same time, the second motor of the second adjustment mechanism drives the second lead screw, causing the movable block and the clamping mechanism to move longitudinally, adjusting the longitudinal distance between the two, thereby achieving the effect of flexibly adjusting the relative position of the milling cutter and the workpiece. This design solves the problems of the existing technology where the position of the milling mechanism is fixed or can only be simply adjusted within a limited range, the scope of application is limited, and the clamping structure cannot adapt to different specifications of workpieces. At the same time, the stable design of the clamping assembly can ensure that the workpiece will not be affected by the loosening of the clamp during the processing, further improving the stability of the processing and meeting diverse processing needs.

[0019] Secondly, in this invention, during the application of this technical solution, by setting up a flipping structure in the telescopic module, the annular adjustment module, and the clamping module, the electric push rod of the telescopic module can be extended and retracted during use, driving the annular adjustment module and the clamping module to rise and fall, accurately adjusting the workpiece height to fit the milling cutter; the third motor of the annular adjustment module drives the gear, meshing the gear ring to drive the slip ring and the workpiece to rotate, realizing the adjustment of the workpiece circumferential angle; the fourth motor of the clamping module can also drive the rotating shaft to drive the bearing plate and the workpiece to flip, completing the workpiece flipping or tilt angle adjustment, thereby achieving the effect of multi-dimensional adjustment of the workpiece processing angle. This design solves the problems of existing technologies such as the inability of the fixture to flip, the limitation of the workpiece processing angle, and the need for frequent workpiece disassembly leading to large positioning errors. Among them, the annular adjustment module can complete the processing of different circumferential surfaces without frequent workpiece disassembly, and the flipping structure can make it easier to remove attached debris when adjusting the angle, providing assistance for subsequent debris cleaning, further improving processing efficiency and accuracy;

[0020] Thirdly, in this invention, during the application of this technical solution, the cleaning component allows the air pump to be started simultaneously during milling. The high-pressure gas generated by the air pump is delivered to the jet pipe through a hose. The metal arbitrarily bent air pipes on both sides of the jet pipe can flexibly adjust the bending angle according to the specific location of the debris, precisely guiding the high-pressure gas to the workpiece processing area below the clamping module, efficiently blowing away the granular debris generated during processing, thereby achieving the effect of real-time and efficient debris cleaning. This design solves the problems of the lack of convenient debris flushing structure, the difficulty of debris cleaning, and the impact of debris accumulation on processing accuracy and causing fixture tilting in the prior art. The adjustability of the metal arbitrarily bent air pipes ensures a comprehensive cleaning range, thoroughly blowing away debris from the workpiece and fixture, reducing debris interference with processing, reducing the cleaning burden on operators, and ensuring the accuracy of workpiece positioning, further improving the overall processing quality.

[0030] Example

[0031] Please see Figures 1-8 In this embodiment of the invention, the CNC lathe reinforced milling device includes a housing 1, a first adjustment mechanism 2 is fixedly installed on one side of the housing 1, a milling machine 5 is fixedly installed on the top of the first adjustment mechanism 2, a milling cutter 4 is installed on the output end of the milling machine 5 by screws, a second adjustment mechanism 3 is fixedly installed on the back of the housing 1, and a clamping mechanism 6 is fixedly installed on the top of the second adjustment mechanism 3.

[0032] The clamping mechanism 6 includes a connecting arm 61, which is fixedly mounted on the top of the second adjusting mechanism 3. A base frame 62 is fixedly mounted on the outer end of the connecting arm 61, and a telescopic module 63 is fixedly mounted on the outer end of the base frame 62. An annular adjusting module 64 is fixedly mounted on the top of the telescopic module 63, and a clamping module 65 is fixedly mounted on the inner side of the annular adjusting module 64. During the application of this device, the workpiece is first fixed by the clamping mechanism 6. Then, according to the processing requirements, the position of the milling machine 5 and the milling cutter 4 is adjusted by the first adjusting mechanism 2 so that the milling cutter 4 can be accurately aligned with the area to be processed on the workpiece. After the milling machine 5 is started, its output end drives the milling cutter 4 to rotate at high speed, thereby performing milling processing on the workpiece. The screw setting facilitates the subsequent replacement of different types of milling cutters 4 according to processing requirements, improving the efficiency of the device. The system is adaptable to different processing scenarios. Simultaneously, the second adjustment mechanism 3 can move the clamping mechanism 6 as a whole, thereby adjusting the relative position between the workpiece and the milling cutter 4. This ensures that different processing parts of the workpiece can precisely engage with the milling cutter 4, avoiding the problem of limited processing range due to fixed positions. During processing, if the workpiece height needs to be adjusted, the telescopic module 63 in the clamping mechanism 6 can raise and lower the annular adjustment module 64 and the clamping module 65, placing the workpiece at a more optimal processing height and further improving processing accuracy. The annular adjustment module 64 can then rotate the clamping module 65 and the workpiece, enabling processing of different circumferential surfaces of the workpiece without frequent workpiece disassembly, reducing positioning errors and improving processing efficiency. Throughout the process, all mechanisms work together to ensure stable and efficient milling.

[0033] Please see Figures 4-7The cleaning component 633 includes an air pump 6331 and a connecting rod 6332. The air pump 6331 is fixedly installed on the top of the base frame 62 near the fixed seat 631. The connecting rod 6332 is fixedly installed on the lower end of the annular rail 641 near the milling machine 5. An air jet pipe 6333 is fixedly installed on the outer end of the connecting rod 6332. Metal arbitrary bending air pipes 6334 are fixedly installed on both sides of the air jet pipe 6333 in a linear arrangement with equal spacing. A hose 633 is fixedly installed at the output end of the air pump 6331. 5. The output end of the hose 6335 is connected to the input end of the jet pipe 6333. During the application of this device, when chips are generated during milling, the cleaning component 633 starts working, and the air pump 6331 starts to generate high-pressure gas. The high-pressure gas is delivered to the jet pipe 6333 through the hose 6335 connected to the output end of the air pump 6331. Because the hose 6335 has a certain degree of flexibility, it can flexibly adapt to the position changes of the jet pipe 6333 with the annular rail 641, ensuring the gas delivery process. Unobstructed operation; after receiving high-pressure gas, the jet pipe 6333 diverts the gas to the linearly arranged metal flexible air pipes 6334 with equal spacing on both sides. The operator can manually adjust the bending angle of the metal flexible air pipes 6334 according to the specific location of the debris, so that the jet direction is precisely aimed at the debris accumulation area below the clamping module 65, realizing directional jet cleaning. This multi-nozzle and flexible design can fully cover the processing area below the clamping module 65, avoiding cleaning dead corners, effectively blowing debris away from the workpiece and clamping structure, preventing debris adhesion from affecting subsequent processing accuracy, and reducing the workload of manual cleaning. At the same time, the connecting rod 6332 provides stable support for the jet pipe 6333, ensuring that the jet pipe 6333 remains stable during the jet process, avoiding the jet pipe 6333 from shifting due to airflow impact, further ensuring the stability of the cleaning effect, allowing the entire milling process to continue in a clean environment, indirectly improving processing efficiency and product quality.

[0034] Please see Figures 5-7The annular adjustment module 64 includes an annular rail 641, which is fixedly mounted on the top of the electric push rod 632. A slip ring 643 is rotatably connected inside the annular rail 641. A clamping module 65 is fixedly mounted on the inner side of the slip ring 643. A drive assembly 644 is fixedly mounted on one side of the annular rail 641. The drive assembly 644 includes a fixed arm 6441, a connecting ring 642, and a toothed ring 6442. The connecting ring 642 is fixedly mounted on the inner side of the slip ring 643. The fixed arm 6441 is fixedly mounted on the inner side of the annular rail 641. A mounting arm 6443 is fixedly mounted on the outer end of the back of the fixed arm 6441. A third motor is fixedly mounted on the front side of the mounting arm 6443. 6444, the output end of the third motor 6444 passes through the mounting arm 6443 and is fixedly mounted with a gear 6445. A gear ring 6442 is fixedly mounted on the front side of the connecting ring 642. The gear 6445 and the gear ring 6442 are meshed together. Support rods 6446 are fixedly mounted at equal intervals in a linear arrangement at the bottom of the fixed arm 6441. The bottom of the support rods 6446 passes through the base frame 62, and the support rods 6446 and the base frame 62 are slidably connected. During the application of this device, when it is necessary to adjust the circumferential angle of the clamping module 65 and the workpiece, the drive component 644 in the annular adjustment module 64 starts working. After the third motor 6444 of the drive component 644 starts, its output end passes through... The mounting arm 6443 drives the gear 6445 to rotate. Since the gear 6445 meshes with the toothed ring 6442 fixed to the front of the slip ring 643, the rotation of the gear 6445 will drive the toothed ring 6442 to rotate synchronously, which in turn will drive the slip ring 643, which is fixed to the toothed ring 6442, to rotate along the inside of the annular rail 641. The clamping module 65 is fixed inside the slip ring 643. When the slip ring 643 rotates, it will drive the clamping module 65 and the workpiece to rotate together, realizing flexible adjustment of the circumferential angle of the workpiece. This gear 6445 meshing transmission method can ensure the smoothness and accuracy of angle adjustment, allowing different circumferential surfaces of the workpiece to be quickly switched to the processing position without frequent disassembly and reassembly of the workpiece. This effectively reduces positioning errors and improves processing efficiency. Meanwhile, the linearly arranged support rods 6446 at equal intervals at the bottom of the fixed arm 6441 play a stabilizing role during the operation of the annular adjustment module 64. When the annular adjustment module 64 rises and falls with the electric push rod 632 or the slip ring 643 drives the clamping module 65 to rotate, the support rods 6446 slide synchronously along the base frame 62, providing vertical support and guidance for the annular adjustment module 64. This prevents the annular adjustment module 64 from tilting or swaying due to its own weight or workpiece pressure, further ensuring the positional stability of the clamping module 65 and the workpiece, ensuring accurate subsequent milling operations, and reducing processing deviations caused by structural instability.

[0035] Please see Figures 5-7The clamping module 65 includes a side arm 651, which is fixedly installed at the middle of both ends of the inner side of the slip ring 643. A rotating shaft 652 is rotatably connected to the inner side of the side arm 651. A bearing plate 653 is fixedly installed on the rotating shaft 652. A clamping assembly 655 is fixedly installed on the side of the bearing plate 653 near the slip ring 643. A fourth motor 654 is fixedly installed on the outer side of the outer end of one side arm 651. The output end of the fourth motor 654 passes through the end of the side arm 651 and is fixedly connected to the end of the rotating shaft 652. The clamping assembly 655 includes a rail frame 6551, which is fixedly installed on the back of the bearing plate 653. A sixth motor 6552 is fixedly installed at one end of the rail frame 6551. The output end of the sixth motor 6552 passes through the rail frame 6551. A third lead screw 6553 is fixedly installed. The two ends of the third lead screw 6553 have opposite threads. Both ends of the third lead screw 6553 are threadedly connected to sliding blocks 6554. The sliding blocks 6554 are slidably connected to the two ends inside the rail frame 6551. A clamping arm 6555 is fixedly installed on the top of the sliding block 6554. A clamping plate 6556 is fixedly installed on the inner side of the clamping arm 6555. During the application of this device, when fixing the workpiece, the sixth motor 6552 of the clamping assembly 655 under the clamping module 65 starts first. The output end of the sixth motor 6552 passes through the rail frame 6551 and drives the third lead screw 6553 to rotate. Since the two ends of the third lead screw 6553 have opposite threads and both ends are threadedly connected to sliding blocks 6554, at the same time... Sliding blocks 6554 are slidably connected inside the rail frame 6551. Rotation of the third lead screw 6553 causes the two sliding blocks 6554 to move in opposite directions along the rail frame 6551. The clamping arm 6555 fixed to the top of the sliding block 6554 moves synchronously with the sliding block 6554, thereby causing the clamping plate 6556 on the inner side of the clamping arm 6555 to move closer to the workpiece until it is tightly fitted to the workpiece surface, achieving stable clamping of the workpiece. This bidirectional synchronous clamping method ensures uniform force on the workpiece, avoids workpiece displacement during clamping, adapts to the fixing requirements of workpieces of different sizes, and reduces processing deviations caused by unstable clamping. When it is necessary to adjust the workpiece's flipping angle to process different surfaces, the fourth motor 654 of the clamping module 65 is activated. The output end of the machine 654 passes through the side arm 651 and drives the rotating shaft 652 to rotate. The bearing plate 653 fixed on the rotating shaft 652 rotates synchronously with the rotating shaft 652. The clamping assembly 655 fixed on the back of the bearing plate 653 and the clamped workpiece flip together with the bearing plate 653. The tilt angle of the workpiece can be flexibly adjusted or the workpiece can be flipped. Multi-sided processing can be completed without disassembling the workpiece, reducing positioning errors caused by multiple clamping and improving processing efficiency. Throughout the process, the side arm 651 provides stable support for the rotating shaft 652, and the rail frame 6551 provides motion guidance for the third lead screw 6553 and the sliding block 6554. The coordinated operation of each component not only ensures the stability of workpiece clamping but also realizes flexible adjustment of the workpiece angle, providing a foundation for subsequent precision milling.

[0036] Please see Figure 1 -Figure 4 and Figure 8The first adjustment mechanism 2 includes a side rail 21, which is fixedly installed on one side of the machine housing 1. A first lead screw 22 is rotatably connected inside the side rail 21. A first motor 23 is fixedly installed at one end of the side rail 21. The output end of the first motor 23 passes through the side rail 21 and is connected to the end of the first lead screw 22. A first slider 24 is threadedly connected to the outer surface of the first lead screw 22. The first slider 24 is slidably connected to the inside of the side rail 21. The milling machine 5 is fixedly installed on the top of the first slider 24. The second adjustment mechanism 3 includes a guide rail 31, which is fixedly installed on the upper back of the machine housing 1. A second motor 32 is fixedly installed at one end of the guide rail 31. A second lead screw 33 is fixedly installed through the guide rail 31 and is rotatably connected to the guide rail 31. Inside the rail 31, the outer surface of the second lead screw 33 is threadedly connected to a movable block 34. The connecting arm 61 is fixedly installed on the top of the movable block 34. The telescopic module 63 includes a fixed seat 631, which is fixedly installed on the front end of the base frame 62. An electric push rod 632 is fixedly installed on the top of the fixed seat 631. An annular adjustment module 64 is fixedly installed on the top of the electric push rod 632. A cleaning component 633 is provided on the base frame 62. The cleaning end of the cleaning component 633 is located directly below the clamping module 65. During the application of this device, when it is necessary to adjust the position of the milling machine 5, the first motor 23 in the first adjustment mechanism 2 is started. The output end of the first motor 23 drives the first lead screw 22 inside the side rail 21 to rotate. Since the first lead screw 22 and the first slider 24 are threaded together... The first slider 24 is slidably connected to the inside of the side rail 21. Rotation of the first lead screw 22 causes the first slider 24 to slide along the side rail 21, thereby causing the top-fixed milling machine 5 to move synchronously. This lead screw drive method enables precise adjustment of the position of the milling machine 5, allowing the milling cutter 4 to quickly align with the workpiece's processing area, improving processing positioning efficiency. When the position of the clamping mechanism 6 needs adjustment, the second motor 32 in the second adjustment mechanism 3 starts. The output end of the second motor 32 drives the second lead screw 33 inside the guide rail 31 to rotate. The second lead screw 33 is threadedly connected to the movable block 34, causing the movable block 34 to slide along the guide rail 31. The connecting arm 61 fixed at the top of the movable block 34 moves with the movable block 34, thereby causing the clamping mechanism 6 to adjust its overall position, allowing for flexible adjustment. The relative distance between the workpiece and the milling cutter 4 can be changed to meet the processing needs of different parts of the workpiece and avoid limiting the processing range. When the workpiece height needs to be adjusted, the electric push rod 632 in the telescopic module 63 is activated. The output end of the electric push rod 632 extends or shortens, driving the top fixed ring-shaped adjustment module 64 to rise and fall, thereby adjusting the workpiece height so that the workpiece is always in a height position suitable for milling and ensuring processing accuracy. At the same time, the cleaning component 633 on the base frame 62 can work synchronously during the processing. Its cleaning end is located directly below the clamping module 65, which can clean up the chips generated during processing in a timely manner, avoiding chip accumulation that affects the processing process and reducing the amount of subsequent cleaning work. The entire process ensures that the milling process is carried out stably and efficiently through the orderly operation of each mechanism.

[0037] The working principle of this invention is as follows: During the application of this equipment, in the pre-processing preparation stage, the operator first places the workpiece to be milled between the clamping plates 6556 of the clamping module 65 of this device, and then starts the sixth motor 6552. Through the power transmission at the output end of the sixth motor 6552, the third lead screw 6553 inside the rail frame 6551 of the clamping assembly 655 rotates. Since the threads at both ends of the third lead screw 6553 rotate in opposite directions, the two sliding blocks 6554 connected by the threads on their outer surfaces will slide smoothly in opposite directions along the inner rail 21 of the rail frame 6551, while the clamping arm 6555 fixed at the top of the sliding block 6554 will... The sliding block 6554 moves synchronously until the clamping plate 6556 on the inner side of the clamping arm 6555 is in close contact with the workpiece surface, thus achieving a stable clamping of the workpiece. The rail frame 6551 provides a stable mounting base and precise motion guidance for the third lead screw 6553 and the sliding block 6554, ensuring that the sliding block 6554 does not deviate during movement. The clamping arm 6555 effectively connects the sliding block 6554 and the clamping plate 6556, converting the moving force of the sliding block 6554 into a clamping force and transmitting it to the clamping plate 6556. The clamping plate 6556 directly contacts the workpiece. This clamping structure allows for flexible adjustment of the clamping distance according to the workpiece size, enabling it to adapt to workpieces of different specifications during use, thereby effectively expanding the applicability of this device. Simultaneously, the clamping plate 6556 has a large contact area with the workpiece, ensuring that the workpiece will not be affected by loosening during subsequent processing, thus maintaining machining accuracy. After the workpiece is clamped, according to the specific processing requirements of the workpiece, the first motor 23 of the first adjusting mechanism 2 and the second motor 32 of the second adjusting mechanism 3 are activated respectively. After the first motor 23 is activated, its output end drives the first lead screw 22 inside the side rail 21 to rotate. The first slider 2 is threadedly connected to the outer surface of the first lead screw 22. 4 will slide along the internal channel of the side rail 21, while the milling machine 5 fixed on the top of the first slider 24 will move synchronously with the first slider 24. Through this series of movements, the initial position of the milling machine 5 and the milling cutter 4 fixed by screws at the output end of the milling machine 5 in the horizontal direction is adjusted, so that it can accurately adapt to the lateral position requirements of the workpiece to be processed area during use. The side rail 21 provides reliable installation space and motion guidance for the first lead screw 22 and the first slider 24. At the same time, through the transmission action of the first lead screw 22, the rotational motion of the first motor 23 is converted into the linear motion of the first slider 24, ensuring the accuracy of position adjustment.Meanwhile, after the second motor 32 is started, its output end drives the second lead screw 33 inside the guide rail 31 to rotate. The movable block 34, which is threaded on the outer surface of the second lead screw 33, slides along the inner rail 21 of the guide rail 31. The connecting arm 61 fixed at the top of the movable block 34 moves synchronously with the movable block 34. The base frame 62 fixed at the outer end of the connecting arm 61 and the clamping mechanism 6 connected on the base frame 62 also move accordingly. Through this process, the initial longitudinal distance between the clamping mechanism 6 and the milling cutter 4 is adjusted, so that the workpiece can be kept within the effective range of milling during use. The guide rail 31 provides a stable installation base and motion guide for the second lead screw 33 and the movable block 34. At the same time, through the transmission of the second lead screw 33, the rotational motion of the second motor 32 is converted into the linear motion of the movable block 34. Through the coordinated cooperation of the first adjustment mechanism 2 and the second adjustment mechanism 3, this technical solution can realize the flexible adjustment of the lateral and longitudinal relative positions between the milling cutter 4 and the workpiece, thereby solving the problem in the background technology that the position of the milling machine 5 is fixed or can only be simply adjusted within a limited range.

[0038] Once the machining process begins, if the lateral position of the milling cutter 4 needs to be adjusted midway through machining, the first motor 23 can be restarted. Through the coordinated transmission of the first lead screw 22 and the first slider 24, the milling machine 5 and the milling cutter 4 are driven to move precisely along the side rail 21 until the milling cutter 4 reaches the designated machining position. The milling machine 5 provides continuous power support for the milling cutter 4, enabling the milling cutter 4 to stably cut the workpiece under the drive of the output end of the milling machine 5. The screws are used to fix the milling cutter 4, allowing for convenient replacement and maintenance during use, ensuring the continuity of the machining process. When it is necessary to adjust the position of the workpiece in the longitudinal direction, the second motor 32 is started, and the rotation of the second lead screw 33... The movable block 34 slides along the guide rail 31. The connecting arm 61 at the top of the movable block 34, the base frame 62 at the outer end of the connecting arm 61, and the clamping mechanism 6 on the base frame 62 move synchronously with the movable block 34. This movement changes the longitudinal relative position of the workpiece and the milling cutter 4, so that different longitudinal machining requirements can be met during use. If it is necessary to adjust the height of the workpiece to match the machining position of the milling cutter 4, the electric push rod 632 in the telescopic module 63 is activated. The output end of the electric push rod 632 will extend or shorten as needed. The annular adjustment module 64 connected to its top and the clamping module 65 inside the annular adjustment module 64 will rise and fall synchronously with the electric push rod 632, thereby adjusting the workpiece to a height that matches the machining surface and the milling cutter 4. The fixed base 631 The design provides stable mounting support for the electric push rod 632, ensuring that it does not wobble during operation. Simultaneously, a support rod 6446 mounted on the base frame 62 penetrates the base frame 62 and maintains a slidable connection with it. The top of the support rod 6446 is fixedly connected to the bottom of the fixed arm 6441 in the annular adjustment module 64. When the electric push rod 632 drives the annular adjustment module 64 to rise or fall, the support rod 6446 slides along the through hole in the base frame 62. By providing the support rod 6446, additional guidance and support are provided for the rising and falling of the annular adjustment module 64, preventing tilting during use and ensuring the stability of the adjustment process, thereby further improving processing efficiency and quality. When it is necessary to adjust the circumferential angle of the workpiece to process different circumferential surfaces, the third motor 6444 in the drive assembly 644 is activated. The output end of the third motor 6444 drives the gear 6445 at its front end to rotate. Since the gear 6445 meshes with the toothed ring 6442 fixed on the front side of the slip ring 643, the toothed ring 6442 will rotate synchronously with the gear 6445. The slip ring 643 fixed to the toothed ring 6442 will rotate along the inner rail 21 of the annular rail 641. The clamping module 65 fixed on the inner side of the slip ring 643 and the workpiece will rotate synchronously with the slip ring 643, ultimately realizing the angle adjustment of the workpiece in the circumferential direction. By setting the annular rail 641, a stable rotation support and precise guidance are provided for the slip ring 643, ensuring that the slip ring 643 will not deviate during rotation.By setting the fixed arm 6441, a reliable mounting base is provided for the mounting arm 6443, which is used to fix the third motor 6444, ensuring the stability of the third motor 6444 during operation. This circumferential adjustment structure allows for the machining of different circumferential surfaces without frequent disassembly of the workpiece during use, thereby avoiding positioning errors caused by multiple clamping and effectively improving machining accuracy. If it is necessary to flip the workpiece or adjust the tilt angle of the workpiece, the fourth motor 654 in the clamping module 65 is activated. The output end of the fourth motor 654 drives the rotating shaft 652 connected to the inner side of the side arm 651 to rotate. The bearing plate 653 fixed on the rotating shaft 652 will rotate synchronously with the rotating shaft 652. The clamping assembly 655 and the workpiece installed on the 653 will rotate with the support plate 653 until the workpiece reaches the specified machining angle. The side rail 21 provides a stable mounting support for the rotating shaft 652, ensuring that the rotating shaft 652 can rotate smoothly. By setting the rotating shaft 652, the support plate 653 can rotate flexibly. By setting the support plate 653, a stable mounting base is provided for the clamping assembly 655. The workpiece rotation not only allows the machining angle to be directly adjusted during use to meet the multi-face machining requirements, thus solving the problem of the workpiece machining angle being limited due to the inability of the fixture to rotate in the background technology, but also makes it easier for the debris attached to the surface of the fixture or workpiece to fall off during the rotation process, assisting in the subsequent debris cleaning work.

[0039] Throughout the milling process, the cleaning component 633 of this device is activated simultaneously to handle the granular debris generated during machining. The operator activates the air pump 6331 within the cleaning component 633. After the air pump 6331 starts working, it generates high-pressure gas, which is delivered to the jet pipe 6333 through the hose 6335 connected to the output end of the air pump 6331. The metal flexible air pipes 6334 installed on both sides of the jet pipe 6333 guide the high-pressure gas to the workpiece machining area below the clamping module 65, efficiently blowing away the debris generated during machining. By setting up the air pump 6331, a continuous high-pressure air source is provided for the cleaning work, ensuring the effectiveness of debris removal; the hose 6335 is used to deliver high-pressure gas, and the hose 6335 has a certain degree of flexibility. The design ensures that the movement of other mechanisms will not hinder its use. The air jet pipe 6333 provides a stable mounting base for the metal arbitrarily bent air pipe 6334. The arbitrarily bent metal air pipe 6334 allows for flexible adjustment of the bending angle of the air jet pipe 6333 based on the specific location of the debris, ensuring comprehensive coverage of the processing area. This real-time cleaning structure directly blows debris away from the workpiece and fixture, effectively solving the problems of lacking convenient debris flushing structures and difficulty in debris cleaning in the prior art. It reduces the impact of debris on processing accuracy, lowers the cleaning burden on operators, and prevents debris accumulation that could cause fixture tilting, ensuring accurate workpiece positioning and further improving processing quality.

[0040] This technical solution organically integrates the first adjusting mechanism 2, the second adjusting mechanism 3, the telescopic module 63, the annular adjusting module 64, the clamping module 65, and the cleaning component 633, enabling these mechanisms to cooperate and work together to form a complete processing system. From workpiece clamping and fixing, to adjusting the lateral, longitudinal, and height positions between the milling cutter 4 and the workpiece, to adjusting the workpiece's circumferential and flip angles, and finally to the synchronous cleaning of debris during processing, the entire process achieves full automation and flexible operation. Compared to the background technology, which has a simple structure, single function, and large limitations in application, this solution offers significant advantages. This milling device features a multi-dimensional adjustment structure, allowing for flexible adjustment of the position and angle of each component according to different processing requirements. Its efficient cleaning structure ensures timely removal of debris during processing, significantly improving processing efficiency, accuracy, and overall usability while reducing operator workload. It fully meets the demands of modern machining for efficient, precise, and flexible equipment. In terms of processing adaptability, accuracy, and ease of operation, it represents an optimization and improvement over traditional milling devices, providing a superior solution for milling processes in the machinery manufacturing industry.
