DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment 1: Reference Figure 1-Figure 6 , a tool feeding structure for a rotary cutting device, comprising: a transmission component, a clamping buffer component and a spray component; The transmission assembly is used to greatly adjust the feed rate of the tool, and the transmission assembly includes a base 1, a mounting plate 3 fixedly connected to the base 1, and a sliding plate 5 slidably connected to the mounting plate 3; A feed box 9 is fixedly connected to one side of the sliding plate 5, and a pushing component for pushing the tool is arranged inside the feed box 9; The clamping and buffering assembly is used to clamp and fix the tool and to buffer and protect the tool from impact. The clamping and buffering assembly includes two first threaded rods 10 rotatably connected to the inside of the feed box 9 and two nuts 11 respectively threadedly connected to the two first threaded rods 10; The two nuts 11 are fixedly connected with a clamping plate 12, and a groove 33 is provided on one side of the two clamping plates 12. The upper and lower sides of the feed box 9 are fixedly connected with a second motor 38. The driving ends of the two second motors 38 are respectively fixedly connected to the two first threaded rods 10. The clamping plate 12 is provided with a sliding component for driving the tool to slide and feed stably. In addition, the sliding assembly includes two groups of guide rods 13 respectively fixedly connected to the two clamping plates 12, a group of guide rods 13 is provided with two, two first springs 14 are fixedly connected to the two clamping plates 12, one group of guide rods 13 is slidably connected to a first push plate 15 fixedly connected to the two first springs 14, and the other group of guide rods 13 is slidably connected to a second push plate 16 fixedly connected to the other two first springs 14, the bottom of the first push plate 15 is fixedly connected to three first blocks 17, and the top of the second push plate 16 is fixedly connected to three second blocks 18; The spray assembly is used to spray cutting oil to the tool and the cutting area according to the amplitude of the vibration. The spray assembly includes two groups of second springs 23 respectively fixedly connected to the two sides of the feed box 9. A group of second springs 23 is provided with two. Two third springs 26 are fixedly connected to the two sides of the feed box 9 adjacent to the two groups of second springs 23. In this embodiment, the structure of the two first threaded rods 10, the nuts 11 and the clamping plates 12 in the clamping buffer assembly can effectively clamp and fix the tool. During the peeling process, the tool will be subjected to a large cutting force and impact force, and the two clamping plates 12 can stably clamp the tool from both sides to prevent the tool from loosening or deflecting during the working process, thereby ensuring the safety and stability of the cutting process. The strong cutting force will not cause the tool to shake, thereby ensuring the flatness and finish of the processed surface; Furthermore, the guide rod 13, the first spring 14, the first push plate 15 and the second push plate 16 provided on the clamping plate constitute a sliding assembly, which can not only assist the sliding feeding of the tool, but also buffer the impact suffered by the tool. When the tool is subjected to an instantaneous impact, the first spring 14 will undergo elastic deformation to absorb part of the impact force, thereby preventing the impact force from being directly transmitted to the tool and other parts of the device, protecting the tool from damage, and also reducing the vibration and wear of the device, thereby extending the overall service life of the device.

[0021] Embodiment 2: Reference Figure 1-Figure 6 Compared with the first embodiment, in this embodiment, a fixed plate 2 is fixedly connected to the top of the base 1, two slide grooves 4 are provided on the mounting plate 3, a sliding plate 5 is slidingly connected to the two slide grooves 4, a ball nut 6 is rotatably connected to the side of the sliding plate 5 away from the feed box 9, a ball screw 7 threadedly connected to the ball nut 6 is rotatably connected to one side of the fixed plate 2, a first motor 8 is fixedly connected to the side of the fixed plate 2 away from the ball screw 7, and a driving end of the first motor 8 is fixedly connected to the ball screw 7.

[0022] The pushing assembly includes a second threaded rod 29 rotatably connected to one side of the inside of the feed box 9, and a first bevel gear 30 is fixedly connected to the second threaded rod 29. A rotating shaft 31 is rotatably connected to one side of the inside of the feed box 9 close to the first bevel gear 30, and a second bevel gear 32 is fixedly connected to the side of the rotating shaft 31 close to the first bevel gear 30. A threaded groove 34 matching the second threaded rod 29 is provided on one side of the first push plate 15 and the second push plate 16 close to the second threaded rod 29. A third motor 39 is fixedly connected to the top of the feed box 9 and on a side adjacent to the second motor 38, and a driving end of the third motor 39 is fixedly connected to the rotating shaft 31.

[0023] In this embodiment, the transmission assembly can realize a large-scale advancement adjustment of the tool feed amount under the drive of the first motor 8 through the cooperation of the base 1, the mounting plate 3, the sliding plate 5, the ball screw 7 and the ball nut 6. This structural design makes the tool feed motion stable, and the advancement distance of the tool each time can be controlled according to the preset processing parameters, thereby ensuring that the thickness of the processed product is uniform and the size is accurate, effectively improving the processing quality and qualified rate of the product.

[0024] Furthermore, the second threaded rod 29 in the push assembly cooperates with the first bevel gear 30, the second bevel gear 32 and the third motor 39 to further refine the feed control of the tool. By rotating the second threaded rod 29, the positions of the first push plate 15 and the second push plate 16 can be accurately adjusted, thereby achieving fine-tuning of the feed of the cutting tool 35. This fine-tuning function is particularly important when performing fine processing or compensating for tool wear, which can ensure that the tool always remains in the best cutting position, extend the service life of the tool, and also improve the processing accuracy and stability of the entire rotary cutting equipment.

[0025] Embodiment three: Reference Figure 4-Figure 7Compared with the first and second embodiments, the seismic guide assembly in this embodiment includes two first seismic guide plates 19 fixedly connected to both sides of the first push plate 15, and second seismic guide plates 20 are fixedly connected to both sides of the second push plate 16, the bottoms of the two first seismic guide plates 19 are fixedly connected to the first shock absorbing plates 21, and the tops of the two second seismic guide plates 20 are fixedly connected to the second shock absorbing plates 22.

[0026] The tops of the two groups of second springs 23 are fixedly connected with the first pressure plate 24, and the first hydraulic buffer 25 fixedly connected to the feed box 9 is arranged below the first pressure plate 24. The bottoms of the two groups of third springs 26 are fixedly connected with the second pressure plate 27, and the second hydraulic buffer 28 fixedly connected to the feed box 9 is arranged above the second pressure plate 27. Two liquid spray pipes 37 are fixedly connected to one side of the feed box 9.

[0027] In this embodiment, the first shock-guiding plate 19, the second shock-guiding plate 20, the first shock-absorbing plate 21 and the second shock-absorbing plate 22 in the shock-guiding assembly can further disperse and absorb the vibrations generated by the tool and the device, further improving the working stability of the tool and the reliability of the equipment.

[0028] In addition, the spray assembly sprays cutting oil to the tool and cutting area according to the amplitude of the vibration of the vibration guide assembly, and has good adaptive performance. During the rotary cutting process, when the vibration amplitude between the tool and the workpiece increases, it means that the cutting force increases or the cutting conditions change. At this time, the second spring 23 and the third spring 26 in the spray assembly will be compressed or stretched accordingly, triggering the operation of the first hydraulic buffer 25 and the second hydraulic buffer 28, and then controlling the spray pipe to spray cutting oil. Cutting oil can effectively reduce the friction coefficient between the tool and the workpiece, reduce the wear of the tool, and at the same time take away the heat generated during the cutting process, prevent the tool from being damaged due to overheating, and improve the durability and processing efficiency of the tool.

[0029] Furthermore, when the cutting force is small, the vibration amplitude is small and the spray volume is reduced accordingly; when the cutting force increases and more lubrication and cooling are required, the spray volume will automatically increase. This not only saves the cost of cutting oil, avoids excessive waste of cutting oil, but also reduces the pollution of cutting oil to the environment. At the same time, reasonable spray lubrication and cooling can improve the working environment of the cutting area, reduce the adhesion of chips, facilitate the discharge and cleaning of chips, and further improve the stability and continuity of the processing process.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
