Description

Technical Field

[0001] This invention relates to the field of CNC boring and milling machine technology, and more specifically, to a high-precision heavy-duty floor-type CNC boring and milling machine and its working method. Background Technology

[0002] Floor-type CNC boring and milling machines are indispensable equipment in the field of heavy machinery processing, and are widely used in industries such as shipbuilding, aerospace, power, and heavy machinery manufacturing for the precision machining of large and heavy workpieces. In the traditional process of machining, the workpiece is often fixed by simple clamps or pressure plates, which has obvious limitations for machining workpieces with complex shapes, huge sizes, and heavy weights.

[0003] First, due to the workpiece's heavy weight, poor rigidity, or irregular shape, it is prone to deformation or displacement during machining, leading to decreased machining accuracy or even scrapping. Traditional fixtures often only provide fixing force in one direction, making it difficult to provide stable support and clamping for variable shapes and center of gravity distributions. This makes it difficult to ensure the workpiece's levelness during machining, thus affecting the final machining accuracy. Furthermore, for heavy workpieces, manual leveling is time-consuming, labor-intensive, and has limited accuracy.

[0004] Secondly, boring and milling processes generate a large amount of chips. If these chips are not removed promptly and effectively, they may accumulate in the machining area, interfering with the normal cutting of the tool and even scratching the workpiece surface. Furthermore, uneven heating of the chips in the machining area can cause localized expansion of the workpiece, further affecting machining accuracy. Traditional chip removal methods, such as manual cleaning or simple air blowing devices, are often ineffective, failing to completely remove chips from deep holes and crevices, and cannot adaptively adjust to changes in the machining position. Especially for high-precision machining, the impact of residual chips on machining quality is even more significant. Summary of the Invention

The position adjustment component is used to adjust the position of the chip removal component so that the chip removal component is directly opposite the machining position of the boring and milling workpiece to be machined.

[0011] As a further optimization of the present invention, the chip removal assembly includes a support frame connected to the position adjustment assembly, and a wind box is installed on the support frame. A connecting hose is installed at one end of the wind box, an air inlet is installed at the other end of the wind box, and a wind cover is installed at the end of the connecting hose away from the wind box.

[0012] As a further optimization of the present invention, a connecting fin is installed inside the air inlet end, and the connecting fin is cylindrical; furthermore, the connecting fin includes a plurality of sub-fins distributed in a ring, and the sub-fins are fixedly connected to the inner wall of the air inlet end.

[0014] As a further optimization of the present invention, a cylinder is installed on the bellows, and the telescopic end of the cylinder is fixedly connected to the bellows cover.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] Example 1: According to the appendix Figure 1 To be continued Figure 4 As shown, the present invention provides a high-precision heavy-duty floor-type CNC boring and milling machine, including a boring and milling machine body 100 and a working area 200.

[0021] The boring and milling machine body 100 includes a base 110, and a sliding frame 120 is connected to the base 110 via an X-axis drive mechanism, so that the sliding frame 120 can move precisely in the X direction.

[0022] A column 130 is mounted on the sliding frame 120, and the column 130 is perpendicular to the sliding frame 120, providing support for Z-axis movement. A support seat 140 is connected to the column 130 through a Z-axis drive mechanism, and the support seat 140 can be raised and lowered along the column 130 in the Z direction.

[0023] The support base 140 is internally connected to a drive tool holder 150 via a Y-axis drive mechanism, allowing the drive tool holder 150 to move in the Y direction. A machining tool 160 is mounted on the rotating end of the drive tool holder 150, which can perform rotary milling or boring. Through the coordinated action of the X, Y, and Z axis drive mechanisms, the machining tool 160 can achieve three-dimensional machining of the workpiece.

[0024] The work area 200 includes a first worktable 210 disposed on one side of the base 110, and a second worktable 220 is mounted on the first worktable 210.

[0025] The second worktable 220 is a core platform for placing and supporting the boring and milling workpiece 300 to be processed. It includes a frame 221 mounted on the first worktable 210. A fixed table 222 is installed on the frame 221. A rotating table 223 is provided inside the fixed table 222. The rotating table 223 can rotate around its own central axis, thereby realizing multi-angle processing of the workpiece.

[0026] The frame 221 is equipped with a rotary device 224, and the rotating end of the rotary device 224 is fixedly connected to the rotary table 223 to drive the rotary table 223 to rotate at a precise angle. A support table 225 is assembled and connected on the rotary table 223. The boring and milling workpiece 300 to be processed is finally placed on the support table 225. The design of the support table 225 can facilitate the loading, unloading and fixing of the workpiece, and has sufficient load-bearing capacity and rigidity.

[0027] To address the issues of securing and leveling heavy workpieces during machining, this invention introduces a clamping and adjusting unit 400. The clamping and adjusting unit 400 is symmetrically distributed on both sides of the support platform 225, used to clamp and fix the workpiece 300 to be machined, and to adjust its level, ensuring that the workpiece maintains a precise posture throughout the machining process.

[0028] To address the issue of timely and effective chip removal during machining, this invention also introduces a chip removal adjustment unit 500. The chip removal adjustment unit 500 is mounted on the support table 225 and is used to remove milling chips from the workpiece 300 to be machined. This unit can precisely move the chip removal device near the tool according to changes in the machining position, achieving efficient chip removal.

[0029] In one embodiment, according to the appendix Figure 5 and attached Figure 6 As shown, the clamping and adjusting unit 400 includes a base plate 410, an adjusting plate 420, and a clamping plate 430. The base plate 410 is mounted on both sides of the support table 225. A horizontal adjusting component 440 is provided between the base plate 410 and the adjusting plate 420 to achieve horizontal calibration of the workpiece 300 to be machined. A telescopic component 450 is provided between the adjusting plate 420 and the clamping plate 430 to achieve clamping and releasing of the workpiece 300 to be machined. The horizontal adjusting component 440 facilitates boring and milling of inclined surfaces at different angles.

[0030] Specifically, the horizontal adjustment assembly 440 includes a connecting shaft 441 mounted on the adjustment plate 420. Both ends of the connecting shaft 441 are rotatably connected to a first connecting seat 442 via bearings, and the first connecting seat 442 is mounted on the base plate 410. It should be noted that the adjustment plate 420 can rotate relative to the base plate 410 within a certain range with the connecting shaft 441 as the central axis through the connecting shaft 441 and the first connecting seat 442.

[0031] In addition, a first hydraulic cylinder 443 is provided on the substrate 410, and the first hydraulic cylinder 443 is rotatably connected to a second connecting seat 444 via a rotating shaft. The second connecting seat 444 is also mounted on the substrate 410. The telescopic end of the first hydraulic cylinder 443 is rotatably connected to a swing arm 445 via a rotating shaft, and the swing arm 445 is fixedly connected to the adjustment plate 420.

[0032] During operation, when the first hydraulic cylinder 443 extends or retracts, it drives the swing arm 445 to swing up and down, thereby driving the adjusting plate 420 to rotate around the connecting shaft 441 at a small angle, achieving the purpose of precise horizontal adjustment of the workpiece 300 to be machined. By controlling the extension and retraction of multiple first hydraulic cylinders 443 on both sides, multi-point, high-precision horizontal adjustment of large workpieces can be achieved, effectively solving the tilting problem caused by the workpiece's own weight or deformation.

[0033] To prevent the adjusting plate 420 from rotating excessively, two sets of limiting posts are also installed on the base plate 410. One set is located directly below the adjusting plate 420 to support and limit its downward rotation; the other set is located between the two sets of first connecting seats 442 to limit its upward rotation. When the adjusting plate 420 rotates to its extreme positions at both ends, the limiting posts limit its rotation, protecting the mechanism from damage.

[0034] The main function of the telescopic assembly 450 is to clamp and release the workpiece. The telescopic assembly 450 includes a second hydraulic cylinder 452 mounted on the adjustment plate 420. The telescopic end of the second hydraulic cylinder 452 is fixedly connected to the clamping plate 430.

[0035] During operation, when the second hydraulic cylinder 452 extends or retracts, the clamping plate 430 moves horizontally relative to the adjusting plate 420, thereby clamping or releasing the workpiece 300 to be machined.

[0036] To ensure the stability of the clamping plate 430 during horizontal movement, the telescopic assembly 450 also includes a limiting block 451 mounted on the adjusting plate 420. Limiting rods 453 are slidably connected to both sides inside the limiting block 451, and the limiting rods 453 are fixedly connected to the clamping plate 430. The sliding of the limiting rods 453 within the limiting block 451 allows the clamping plate 430 to be stably guided, ensuring it maintains the correct posture during telescopic movement and preventing tilting.

[0037] In other embodiments, to further enhance clamping capability and adapt to workpieces of different shapes, at least one set of third connecting seats 460 is installed on both sides of the clamping plate 430, and a third hydraulic cylinder 470 is installed on the third connecting seat 460. The telescopic end of the third hydraulic cylinder 470 passes through the third connecting seat 460 and is fitted with a clamping block 480. These clamping blocks 480, as clamping points that directly contact the workpiece, can be independently extended and retracted by the third hydraulic cylinder 470 to perform multi-point, localized, and precise clamping of the workpiece, which is especially suitable for heavy workpieces with irregular shapes or requiring specific clamping forces.

[0038] When flipping is required, one set of horizontal adjustment components 440 is released from clamping, and another set of horizontal adjustment components 440 is controlled to work, and the workpiece 300 to be processed is clamped and fixed by clamping block 480. During operation, when the first hydraulic cylinder 443 is fully extended, the workpiece 300 to be processed can perform a 90° flipping motion, which facilitates flipping processing of the other processing surface.

[0039] According to the appendix Figure 7 To be continued Figure 10As shown, the chip removal adjustment unit 500 includes a position adjustment component 510 and a chip removal component 520. The position adjustment component 510 is used to adjust the position of the chip removal component 520 so that the chip removal component 520 can be precisely aligned with the machining position of the workpiece 300 to be machined.

[0040] Specifically, the position adjustment assembly 510 includes a first fixing frame 511 mounted on the support platform 225. A first motor 512 is mounted on the first fixing frame 511, and a first threaded rod 513 is mounted on the output shaft of the first motor 512. A first threaded sleeve 514 is threadedly connected to the first threaded rod 513, and a second fixing frame 515 is mounted on the first threaded sleeve 514.

[0041] During operation, the first threaded rod 513 is driven to rotate by the first motor 512, which can drive the second fixed frame 515 to move in the Z-axis direction.

[0042] A second motor 516 is mounted on the second fixed frame 515, and a second threaded rod 517 is mounted on the output shaft of the second motor 516. A second threaded sleeve 518 is threadedly connected to the second threaded rod 517, and an adjusting frame 519 is mounted on the second threaded sleeve 518. The adjusting frame 519 is connected to the chip removal assembly 520.

[0043] The second motor 516 drives the second threaded rod 517 to rotate, which in turn moves the adjusting frame 519 in the X-axis direction. Through the coordinated control of the two motors, the position adjustment component 510 can achieve two-dimensional precise movement and positioning of the chip removal component 520 in the XZ plane, ensuring that the chip removal component 520 is always in the optimal position of the tool cutting point, thereby maximizing the chip removal efficiency.

[0044] In another embodiment, the chip removal assembly 520 includes a support frame 521 mounted on an adjusting frame 519, and a wind box 522 is mounted on the support frame 521. A fan, preferably a high-power centrifugal fan, is installed inside the wind box 522 to generate a high-speed airflow. A connecting hose 523 is installed at one end of the wind box 522 to guide the high-speed airflow generated by the fan to the processing area. An air inlet 524 is installed at the other end of the wind box 522, serving as the air entrance. A hood 525 is installed at the end of the connecting hose 523 away from the wind box 522, directly facing the processing area to concentrate the airflow and remove chips.

[0045] To further optimize the chip removal effect and provide cooling, a connecting fin 526 is installed inside the air inlet 524. The connecting fin 526 is cylindrical, increasing the contact area with the air. Furthermore, the connecting fin 526 includes several sub-fins arranged in a ring, which are fixedly connected to the inner wall of the air inlet 524, further optimizing the heat exchange efficiency when the airflow passes through.

[0046] More importantly, cooling components 527, such as semiconductor cooling chips or evaporators of small refrigeration compressors, are installed on several sub-fins. When air passes through the air inlet 524, it is cooled by the cooling components 527. The cooled airflow enters the air box 522 and is pressurized by the fan before being blown towards the machining area through the connecting hose 523 and the fan shroud 525. The cold airflow can not only efficiently remove chips, but also effectively remove the heat generated during machining, reduce the local temperature of the workpiece and tool, significantly reduce thermal deformation, thereby improving machining accuracy and extending tool life. It effectively suppresses thermal deformation of the workpiece and tool, which is of great significance for improving the accuracy of heavy precision machining.

[0047] In addition, to enable flexible extension, retraction, and positioning of the air shroud 525, a cylinder 528 is installed on the air box 522, and the extension end of the cylinder 528 is fixedly connected to the air shroud 525. The extension and retraction of the cylinder 528 can control the distance between the air shroud 525 and the workpiece, so as to better adapt to different processing depths and workpiece shapes, and ensure maximum chip removal effect.

[0048] Example 2: According to the appendix Figure 1 To be continued Figure 10 As shown, a working method for a high-precision heavy-duty floor-type CNC boring and milling machine includes the following steps: S1. Install the workpiece 300 to be machined onto the support table 225 of the working area 200; S2. The workpiece 300 to be processed is clamped, fixed and horizontally adjusted by the clamping and adjusting unit 400 to ensure that the workpiece maintains a precise posture during processing. S3. During the processing, the chip removal assembly 520 is adjusted by the chip removal adjustment unit 500 to align with the processing position and to remove chips and cool the processing area. S4.

The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
