DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 10A CNC gantry boring and milling grinding machine comprises a base 1, a gantry bracket 2 is fixedly installed in the middle of the base 1, a moving frame 3 is slidably installed on the gantry bracket 2, a working bracket 4 is slidably installed in the middle of the moving frame 3, a working component 5 for processing different metals is installed on one side of the working bracket 4, the working bracket 4 is used to change the working state of the working component 5, and a cleaning component 6 for cleaning is installed on the side of the working bracket 4 away from the working component 5, a moving seat plate 11 is slidably installed on the upper surface of the base 1, and driving components 21 for driving the moving seat plate 11 to move are fixedly installed on both sides of the gantry bracket 2, a CNC table for controlling the operation of the device is provided outside the device, and a hydraulic cylinder for controlling the lifting of the working bracket 4 is installed inside the gantry bracket 2.

[0026] During actual use, the workpiece to be processed is first placed on the movable base plate 11, and then the external CNC table is used to control the CNC table input instructions. The driving component 21 drives the gantry bracket 2 to drive the movable base plate 11 to move to the specified position, thereby accurately controlling the positioning of the processing head. Subsequently, the hydraulic cylinder operates the working bracket 4 to rise and fall to adapt to workpieces of different heights, and the working component 5 is started to perform milling, boring or grinding and other processing procedures, while the cleaning component 6 runs synchronously to remove metal chips generated by the processing to ensure the processing quality and efficiency. The working component 5 can simultaneously have milling, boring, grinding and other functions, so that the device can have higher adaptability and is convenient for processing different metals.

[0027] The working component 5 includes a rotating plate 51, and a plurality of mounting shells 52 distributed in a ring shape are fixedly installed on the side of the rotating plate 51 away from the working bracket 4. A spindle motor 53 is fixedly installed on the side of the rotating plate 51 corresponding to the mounting shell 52. The plurality of mounting shells 52 and the spindle motor 53 are distributed in a cross shape. A connecting component 54 is installed inside the mounting shell 52. A milling cutter 55, a boring cutter 56, and a grinding head 57 are rotatably installed at one end of the plurality of mounting shells 52 away from the center position. The connecting component 54 is used to transmit the kinetic energy output by the spindle motor 53 to the corresponding milling cutter 55, boring cutter 56, and grinding head 57. The grinding head 57 is placed vertically to the mounting shell 52, and the connecting component 54 close to the grinding head 57 is transmitted to the grinding head 57 through a bevel gear.

[0028] When in use, the working component 5 can be rotated to drive different mounting shells 52 to rotate, and then the appropriate milling cutter 55, boring cutter 56, and grinding head 57 can be selected to perform specific processing tasks. The milling cutters 55, boring cutters 56, and grinding heads 57 connected to different mounting shells 52 are designed for different processing requirements, such as milling, grinding, or drilling, to meet diverse processing requirements. Through the precise control of the CNC table, the working component 5 can be quickly switched to different working modes to achieve fast and efficient production conversion. When in use, the corresponding mounting shell 52 is rotated to the working position, which is a position vertically downward and perpendicular to the workpiece. At this time, the spindle motor 53 is started to drive the connecting component 54 at the working position to rotate, and then the connecting component 54 at the working position will drive the corresponding milling cutter 55, boring cutter 56, and grinding head 57 to rotate to perform processing. The entire process is precisely controlled by the CNC table to ensure the accuracy and efficiency of each processing step. This design of the equipment greatly improves work efficiency and reduces the time for replacing different processing tools, so that the flexibility and output of the production line are significantly improved.

[0029] The grinding head 57 and the mounting shell 52 are placed vertically so that the cylindrical surface on the grinding head 57 can completely contact the workpiece, ensuring the processing accuracy. It can not only make the grinding head 57 better fit the workpiece surface, but also improve the heat dissipation efficiency of the grinding head 57, making grinding more efficient and stable.

[0030] The connecting component 54 includes a movable bracket 541, which is slidably mounted inside the mounting shell 52, and the end of the movable bracket 541 extends to the outside of the mounting shell 52. A first rotating cylinder 542 is rotatably mounted on one end of the movable bracket 541, and a second rotating cylinder 543 is mounted on one side of the first rotating cylinder 542. A first sliding rod 544 for driving the second rotating cylinder 543 to work is slidably mounted on a side of the first rotating cylinder 542 close to the second rotating cylinder 543. The first sliding rod 544 and the first rotating cylinder 542 are connected to each other. A first spring 547 is fixedly connected therebetween; a third rotating cylinder 545 is provided on the side of the first rotating cylinder 542 away from the second rotating cylinder 543; a second sliding rod 546 for driving the third rotating cylinder 545 to work is fixedly installed on the side of the first rotating cylinder 542 away from the second rotating cylinder 543; a secondary bevel gear 548 is fixedly installed on one end of the third rotating cylinder 545 away from the first rotating cylinder 542; a main bevel gear 531 is fixedly installed on the driving end of the spindle motor 53, and a plurality of secondary bevel gears 548 are all meshed with the main bevel gear 531.

[0031] During operation, the main bevel gear 531 on the spindle motor 53 drives the sub-bevel gear 548 to rotate, and the rotation of the sub-bevel gear 548 will drive the third rotating cylinder 545 to rotate. Because the second sliding bar 546 is slidably clamped in the inside of the third rotating cylinder 545, the rotation of the third rotating cylinder 545 will drive the second sliding bar 546 and the first rotating cylinder 542 to rotate, and then the rotation of the first rotating cylinder 542 drives the first sliding bar 544 and the second rotating cylinder 543 to work. The second rotating cylinder 543 is directly connected to the corresponding milling cutter 55, boring tool 56, and grinding head 57, so that they can operate efficiently. Through the flexible connection of the second rotating cylinder 543, fast switching under different processing requirements is realized. The efficient operation of the milling cutter 55, boring tool 56, and grinding head 57 not only improves production efficiency, but also reduces downtime caused by tool replacement. Under control, the entire production process becomes smooth and highly automated, ensuring processing accuracy and repeatability, so that product quality is guaranteed. During use, when the mounting shell 52 is in the working position, the first slide bar 544 slides and is locked into the second rotating cylinder 543. At this time, the first rotating cylinder 542 rotates, and the first slide bar 544 can smoothly drive the second rotating cylinder 543 to rotate. At this time, the connecting component 54 is in the non-working position, and its corresponding first slide bar 544 will be detached from the inside of the second rotating cylinder 543. At this time, the first rotating cylinder 542 cannot drive the second rotating cylinder 543 to work, thereby realizing a higher kinetic energy transfer to the connecting component 54 in the working position, ensuring efficient distribution and use of power. This design not only improves the performance of the machine, but also greatly reduces maintenance costs and reduces useless kinetic energy loss.

[0032] A rotating shaft 41 is rotatably installed in the middle of the working bracket 4, a worm gear 42 is fixedly installed in the middle of the rotating shaft 41, and the worm gear 42 extends to the outside of the working bracket 4. A fixed plate 43 is fixedly installed on the side of the working bracket 4 close to the working part 5. The rotating shaft 41 penetrates the fixed plate 43 and is fixedly installed in the middle of the rotating plate 51. A worm 22 for connecting the worm gear 42 is rotatably installed on the upper end of the gantry bracket 2, and a driving motor 24 for driving the worm 22 to rotate is fixedly installed on the top of the gantry bracket 2.

[0033] When the device needs to replace the parts in the working position, it only needs to use the external CNC table for control to drive the working support 4 and the working part 5 to rise. When the working support 4 rises to the top of the gantry support 2, the worm wheel 42 is meshed with the worm 22. At this time, the driving motor 24 drives the worm 22 to rotate, and then the worm 22 will drive the worm wheel 42 and the rotating shaft 41 to rotate, and the rotating shaft 41 will drive the rotating plate 51 to rotate, and then drive the mounting shell 52 and the milling cutter 55, boring cutter 56, and grinding head 57 installed thereon to rotate, and replace the required parts to the working position. The whole process does not require manual intervention and has a high degree of automation. The milling cutter 55, boring cutter 56, and grinding head 57 will only be replaced when the working support 4 is raised to the top of the gantry support 2, which can prevent the milling cutter 55, boring cutter 56, and grinding head 57 from colliding and damaging the workpiece during replacement, and can also prevent any accidents during the replacement process, thereby ensuring the smoothness and safety of the production process.

[0034] A first slide groove 431 and a second slide groove 432 are provided at the outer ring of the fixed plate 43 on one side close to the working component 5. The inner diameter of the first slide groove 431 is smaller than the inner diameter of the second slide groove 432. The movable bracket 541 is slidably clamped in the first slide groove 431. An annular slide groove 433 is provided in the middle of the side of the rotating shaft 41 close to the working component 5. A limiting groove 434 connected to the annular slide groove 433 is provided above the annular slide groove 433. A rotating ring 511 corresponding to the annular slide groove 433 is fixedly installed in the middle of the side of the rotating plate 51 close to the working bracket 4. The rotating ring 5 11 is rotatably installed inside the annular slide groove 433, the internal sliding card of the rotating plate 51 is provided with four evenly distributed sliding plates 513, one side of the sliding plate 513 is fixedly installed with a blocking rod 514, a plurality of mounting grooves 512 corresponding to the sliding plates 513 are opened on the rotating ring 511, the blocking rod 514 is located inside the mounting groove 512, a second spring 515 is fixedly connected between the sliding plate 513 and the rotating plate 51, and a blocking bracket 25 for pushing the sliding plate 513 is fixedly installed on the top of the gantry bracket 2 close to the side of the working part 5.

[0035] Because the movable bracket 541 is slidably clamped in the first sliding groove 431, when the rotating plate 51 is driven to rotate by the rotating shaft 41, the movable bracket 541 slides along the inside of the first sliding groove 431. When the mounting shell 52 is rotated to the working position, the movable bracket 541 will slide from the inside of the first sliding groove 431 to the inside of the second sliding groove 432. Because the diameter of the second sliding groove 432 is larger than that of the first sliding groove 431, when the movable bracket 541 slides into the inside of the second sliding groove 432, it will drive the first rotating cylinder 542 and the first sliding rod 544 to slide, and then slide the first sliding rod 544 into the inside of the second rotating cylinder 543, so as to realize the second rotating cylinder 543. The kinetic energy of the first rotating cylinder 542 is transmitted to the second rotating cylinder 543 and its corresponding milling cutter 55, boring cutter 56 and grinding head 57, while the milling cutter 55, boring cutter 56 and grinding head 57 in the non-working position are restricted by the first slide groove 431 and will not be affected and remain stationary. During the rotation process, the milling cutter 55, boring cutter 56 and grinding head 57 replaced from the working position slide from the inside of the second slide groove 432 to the inside of the first slide groove 431 because of its corresponding movable bracket 541, thereby causing the first rotating cylinder 542 and the first slide rod 544 to lose connection with the second rotating cylinder 543, ensuring that only the milling cutter 55, boring cutter 56 and grinding head 57 in the working position will rotate.

[0036] When the device is in the initial state, a sliding plate 513 above will drive the blocking rod 514 to slide up to the inside of the limiting groove 434 under the action of the second spring 515. At this time, the rotating plate 51 is stuck by the blocking rod 514 and the limiting groove 434. At this time, when the working bracket 4 rises to the top of the gantry bracket 2, the blocking bracket 25 will push the sliding plate 513 above to slide. At this time, the sliding plate 513 will drive the blocking rod 514 to move out from the inside of the limiting groove 434 and enter the inside of the placement groove 512. The rotating ring 511 can be released and then driven by the worm 22 to rotate inside the annular groove 433, completing a cycle of starting process. When the rotating plate 51 rotates so that another milling cutter 55, boring tool 56, and grinding head 57 are driven to the working position, the working bracket 4 will be driven down to process the workpiece on the movable seat plate 11. As the working bracket 4 descends, the blocking bracket 25 loses its pressing effect on the sliding plate 513, and the blocking rod 514 and the sliding plate 513 at the corresponding position will be pushed into the interior of the limit groove 434 under the action of the second spring 515, and the rotating plate 51 will be re-jammed to prepare for the start of the next cycle. Through this precise mechanical linkage and positioning mechanism, the device is ensured to operate continuously and stably with high efficiency and high precision, preventing the working component 5 from being driven to shake when processing the workpiece, thereby causing inaccurate processing.

[0037] The cleaning component 6 includes a fixed frame 61, and a plurality of spring telescopic rods 62 distributed in a cross shape are fixedly installed on the outer ring of the fixed frame 61, and a cleaning brush 63 is fixedly installed on the end of the spring telescopic rod 62 away from the fixed frame 61. The fixed frame 61 is fixedly installed on the end of the rotating shaft 41 away from the working component 5. A cleaning bracket 23 is fixedly installed on the side of the top of the gantry bracket 2 close to the cleaning component 6, and a cleaning comb 231 is fixedly installed on the lower surface of the cleaning bracket 23.

[0038] When in use, the cleaning component 6 can clean the surface of the workpiece as the working bracket 4 descends and the movable seat plate 11 moves, and clean up the metal chips and other debris generated by milling, boring and grinding, to prevent the processing from being affected by debris. When the rotating shaft 41 drives the working component 5 to rotate, it will drive the cleaning component 6 to rotate synchronously. After the processing is completed, when the rotating shaft 41 drives the working component 5 to rotate in a cycle, the cleaning brush 63 will be driven through the cleaning bracket 23, and the cleaning comb 231 can remove the debris on the cleaning brush 63 to facilitate the next work.

[0039] A protective shell 510 is detachably installed in the middle of the rotating plate 51. The protective shell 510 is used to protect the main bevel gear 531 at the driving end of the boring tool 56 and the secondary bevel gear 548 inside the connecting component 54. The protective shell 510 can protect the bevel gear used for transmission, prevent it from being rolled up with debris, and prevent safety hazards to workers. During maintenance, it is only necessary to remove the protective shell 510.

[0040] Working principle: When in use, the working component 5 can be rotated to drive different installation shells 52 to rotate, and then the appropriate milling cutter 55, boring cutter 56, and grinding head 57 can be selected to perform specific processing tasks. The milling cutters 55, boring cutters 56, and grinding heads 57 connected to different installation shells 52 are designed for different processing needs, such as milling, grinding, or drilling, to meet diverse processing requirements. Through the precise control of the CNC table, the working component 5 can quickly switch to different working modes to achieve fast and efficient production conversion. When in use, the corresponding installation shell 52 is rotated to the working position, which is a vertical downward position perpendicular to the workpiece. At this time, the spindle motor 53 is started to drive the connecting component 54 at the working position to rotate, and then the connecting component 54 at the working position will drive the corresponding milling cutter 55, boring cutter 56, and grinding head 57 to rotate to perform processing; The cleaning component 6 can clean the surface of the workpiece as the working bracket 4 descends and the movable seat plate 11 moves, and clean up the metal chips and other debris generated by milling, boring and grinding to prevent the debris from affecting the processing. When the rotating shaft 41 drives the working component 5 to rotate, it will drive the cleaning component 6 to rotate synchronously. After the processing is completed, when the rotating shaft 41 drives the working component 5 to rotate in a cycle, the cleaning brush 63 will be driven through the cleaning bracket 23, and the cleaning comb 231 can remove the debris on the cleaning brush 63.

[0041] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
