Description

Technical Field

[0001] The present invention relates to the technical field of milling cutter discs, and specifically relates to a vertical milling cutter disc provided with a waste chip shielding component. Background Art

[0002] A milling cutter disc is a tool used for milling machining, mainly used for cutting workpieces of various shapes, sizes and materials. During the machining process, the milling cutter disc can rotate to cut the surface of the workpiece to achieve fine cutting during the machining process. The milling cutter disc usually consists of multiple blades, and different blades can be replaced during use to complete the cutting of workpieces of different shapes.

[0003] For example, Chinese Patent No. CN 117696997 B discloses a fine-tuning milling cutter disc system, which includes a cutter disc body, cutting blades, a flange connection disc, a fixing member, a connecting member and a fine-tuning member; the cutter disc body is detachably connected to the flange connection disc through the connecting member; the cutter disc body is provided with an installation groove; the cutting blades are arranged in the installation groove through the fixing member, and there is a gap between the fixing member and the cutting blades for the cutting blades to move finely; the fine-tuning member includes an adjusting block and an adjusting member; an adjusting groove is arranged on the outer peripheral side of the cutter disc body, the adjusting block is slidably connected to the side wall of the adjusting groove, and the adjusting block can contact the cutting blades; the adjusting member is used to drive the adjusting block to approach or move away from the cutting blades. While improving the machining accuracy of parts, this milling cutter disc system can also extend the service life of the milling cutter disc system.

[0004] Through a search of the above patent, the inventor of the present invention found through research that there are still some deficiencies in the actual application scenarios of this milling cutter disc. For example, during milling machining, a large amount of waste chips will be generated when the milling cutter disc rotates at high speed to cut the workpiece. These waste chips have a certain initial velocity and will fly around. Without a suitable protection device, the waste chips are very likely to fly into the nearby drive shaft area, resulting in the waste chips being sandwiched between the drive shaft and related mating parts (such as bearings, etc.). It will act like an abrasive and continuously rub the surfaces of the drive shaft and the mating parts as the drive shaft rotates, thereby accelerating their wear rate and shortening the service life of the parts. Summary of the Invention

[0005] To solve the deficiencies of the prior art, the present invention provides a vertical milling cutter head provided with a waste chip shielding component, thereby solving the problem that in the existing milling cutter head during milling processing, a large amount of waste chips will be generated when the milling cutter head rotates at high speed to cut the workpiece. These waste chips have a certain initial velocity and will fly around. Without a suitable protection device, the waste chips are very likely to fly into the nearby drive shaft area, resulting in the waste chips being sandwiched between the drive shaft and related mating components (such as bearings, etc.). It will be like an abrasive and continuously rub the surfaces of the drive shaft and the mating components as the drive shaft rotates, thereby accelerating their wear rate and shortening the service life of the components.

[0006] The technical solution adopted by the present invention to solve its technical problems is a vertical milling cutter head provided with a waste chip shielding component, including a cutter head body. A cutting edge is fixedly installed at the edge position of the cutter head body. A shielding component is fixedly installed on the upper surface of the cutter head body. The shielding component includes a mounting seat. A magnet is arranged outside the mounting seat. A baffle is fixedly installed outside the magnet. A sector-shaped scraping plate is rotatably connected to the outside of the baffle.

[0007] Preferably, a plurality of groups of card slots are opened on the circumferential outer wall of the mounting seat, and a first threaded hole is opened at the bottom of the card slot.

[0008] Preferably, a plurality of groups of blocks corresponding to the number of card slots are fixedly connected to the inner side of the magnet. A second threaded hole is opened in the middle of the block, and the first threaded hole and the second threaded hole are fixedly connected by bolts.

[0009] Preferably, a plurality of groups of collection grooves are opened on the lower surface of the magnet.

[0010] Preferably, a collection box is fixedly connected to the middle of the sector-shaped scraping plate, and the collection box is made of a metal material that can be adsorbed on the magnet.

[0011] Preferably, a bearing is arranged on the upper surface of the magnet, and the inner ring of the bearing is fixedly connected to the magnet.

[0012] Preferably, a mounting groove is opened on the upper side surface of the sector-shaped scraping plate, and the outer ring of the bearing is fixedly connected to the mounting groove.

[0013] Preferably, threaded holes are symmetrically opened on the side wall of the sector-shaped scraping plate, and a dust blowing component is arranged in the threaded holes. The dust blowing component includes a threaded sleeve threadedly connected to the threaded hole. A dust blowing cylinder is fixedly connected to the end of the threaded sleeve. A filter plate is fixedly connected to one side near the bottom of the inner cavity of the dust blowing cylinder. A rotating shaft is rotatably connected between the side wall of the filter plate and the bottom of the dust blowing cylinder. Vanes are fixedly connected to the circumferential outer wall of the rotating shaft.

[0014] The beneficial effects of the present invention: 1. In the present invention, through the setting of the magnet, the magnet outside the mounting seat will block the waste chips generated during the processing and adsorb them on its surface, avoiding the waste chips from splashing into the area of the accessory drive shaft, thereby reducing the wear rate of the drive shaft and greatly increasing its service life. During the rotation of the mounting seat, the magnet is driven to rotate, and the magnet drives the bearing and the sector-shaped scraper to rotate. When the sector-shaped scraper rotates, due to air resistance, there will be a certain speed difference with the magnet. When the lower surface and side wall of the magnet adsorb waste chips, the sector-shaped scraper will scrape the waste chips on the lower surface of the magnet into the collection tank during rotation, and scrape the waste chips on the magnet into the collection box, thus facilitating the collection of waste chips. After the processing is completed, turn the bolt, and the clamping block is separated from the card slot. At this time, the magnet can be removed from the mounting seat, which is convenient for cleaning the waste chips in the collection tank and the collection box.

[0015] 2. In the present invention, through the setting of the dust blowing assembly, during the rotation of the sector-shaped scraper, the external wind will enter the dust blowing cylinder through the threaded sleeve, and the blades in the dust blowing cylinder will rotate accordingly. During the rotation of the blades, the resistance of the sector-shaped scraper is further increased, so that the rotation speed of the sector-shaped scraper is further reduced, improving the scraping effect on waste chips. At the same time, during the rotation of the blades, the tiny dust floating in the air will be blown away, preventing the dust from spreading to the vicinity of the drive shaft, thereby causing wear of the drive shaft and further increasing the service life of the drive shaft.

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. In conjunction with the specific embodiments, the present invention will be further described. Embodiment 1

[0020] As Figures 1 to 5 shown, a preferred embodiment of the present invention provides a vertical milling cutter head provided with a waste chip shielding component, including a cutter head body 1. A cutting edge 11 is fixedly installed at the edge position of the cutter head body 1. A shielding component 2 is fixedly installed on the upper surface of the cutter head body 1. The shielding component 2 includes a mounting seat 21. A magnet 22 is arranged outside the mounting seat 21. A baffle 221 is fixedly installed outside the magnet 22. A sector-shaped scraping plate 23 is rotatably connected outside the baffle 221. A plurality of groups of clamping grooves 211 are formed on the circumferential outer wall of the mounting seat 21. A first threaded hole 212 is formed at the bottom of the clamping groove 211. A plurality of groups of clamping blocks 222 corresponding to the number of the clamping grooves 211 are fixedly connected inside the magnet 22. A second threaded hole 223 is formed in the middle of the clamping block 222. The first threaded hole 212 and the second threaded hole 223 are fixedly connected by bolts. A plurality of groups of collecting grooves 224 are formed on the lower surface of the magnet 22. A collecting box 231 is fixedly connected in the middle of the sector-shaped scraping plate 23. The collecting box 231 is made of a metal material that can be adsorbed on the magnet 22. A bearing 225 is arranged on the upper surface of the magnet 22. The inner ring of the bearing 225 is fixedly connected with the magnet 22. An installation groove 232 is formed on the upper side of the sector-shaped scraping plate 23. The installation groove 232 is fixedly connected with the outer ring of the bearing 225.

[0021] In this embodiment, during the working process, the mounting seat 21 is connected to an external driving shaft (the external driving shaft is an existing mature technology and will not be elaborated here too much). The driving shaft drives the mounting seat 21 to move to a suitable position and rotate. The mounting seat 21 drives the cutter head body 1 to rotate, and the workpiece is processed by the cutting edge 11. During the processing of the workpiece, the magnet 22 outside the mounting seat 21 will shield and adsorb the waste chips generated during the processing on its surface, avoiding the waste chips from splashing into the area of the accessory driving shaft, thereby reducing the wear speed of the driving shaft and greatly increasing its service life. During the rotation of the mounting seat 21, the magnet 22 is driven to rotate. The magnet 22 drives the bearing 225 and the sector-shaped scraping plate 23 to rotate. Since the sector-shaped scraping plate 23 is sector-shaped, a certain wind resistance will be generated during rotation. Due to the wind resistance, a certain speed difference will be generated between the sector-shaped scraping plate 23 and the magnet 22 during rotation. When the waste chips are adsorbed on the lower surface and side wall of the magnet 22, the sector-shaped scraping plate 23 will scrape the waste chips on the lower surface of the magnet 22 into the collecting groove 224 during rotation, and the waste chips on the magnet 22 are scraped into the collecting box 231, thus facilitating the collection of waste chips. After the processing is completed, the bolt is rotated, and the clamping block 222 is separated from the clamping groove 211. At this time, the magnet 22 can be removed from the mounting seat 21, which is convenient for cleaning the waste chips in the collecting groove 224 and the collecting box 231. Embodiment 2

[0022] As Figures 1 - 5 shown, on the basis of Embodiment 1, the present invention proposes a technical solution: Further, threaded holes 233 are symmetrically formed in the side wall of the sector-shaped scraper 23, and a dust blowing assembly 3 is arranged in the threaded holes 233. The dust blowing assembly 3 includes a threaded sleeve 31 threadedly connected to the threaded holes 233. One end of the threaded sleeve 31 is fixedly connected to a dust blowing cylinder 32. A filter plate 321 is fixedly connected to one side of the inner cavity of the dust blowing cylinder 32 close to the bottom. A rotating shaft 322 is rotatably connected between the side wall of the filter plate 321 and the bottom of the dust blowing cylinder 32. Vanes 323 are fixedly connected to the circumferential outer wall of the rotating shaft 322.

[0023] In this embodiment, when the sector-shaped scraper 23 rotates, the external wind will enter the dust blowing cylinder 32 through the threaded sleeve 31, and the vanes 323 in the dust blowing cylinder 32 will rotate accordingly. During the rotation of the vanes 323, the resistance of the sector-shaped scraper 23 is further increased, so that the rotation speed of the sector-shaped scraper 23 is further reduced, improving the scraping effect on the waste chips. At the same time, during the rotation of the vanes 323, the tiny dust floating in the air will be blown away, preventing the dust from spreading to the vicinity of the drive shaft, thereby causing wear of the drive shaft and further improving the service life of the drive shaft.

[0024] Working principle In use, first connect the mounting base 21 to an external drive shaft (the external drive shaft is a mature existing technology and will not be elaborated here). The drive shaft drives the mounting base 21 to move to a suitable position and rotate. The mounting base 21 drives the cutter head body 1 to rotate, and the workpiece is processed by the cutting edge 11. During the processing of the workpiece, the magnet 22 outside the mounting base 21 will block and adsorb the waste chips generated during the processing on its surface, preventing the waste chips from splashing into the area of the accessory drive shaft, thereby reducing the wear rate of the drive shaft and greatly increasing its service life. During the rotation of the mounting base 21, the magnet 22 is driven to rotate. The magnet 22 drives the bearing 225 and the sector-shaped scraper 23 to rotate. When the sector-shaped scraper 23 rotates, due to air resistance, there will be a certain speed difference with the magnet 22. When the lower surface and side wall of the magnet 22 adsorb waste chips, the sector-shaped scraper 23 will scrape the waste chips on the lower surface of the magnet 22 into the collection groove 224 during rotation, and scrape the waste chips on the magnet 22 into the collection box 231, thus facilitating the collection of waste chips. After the processing is completed, turn the bolt, and the clamping block 222 is separated from the clamping groove 211. At this time, the magnet 22 can be removed from the mounting base 21, which is convenient for cleaning the waste chips in the collection groove 224 and the collection box 231. At the same time, during the rotation of the sector-shaped scraper 23, the external wind will enter the dust blowing cylinder 32 through the threaded sleeve 31, and the blades 323 in the dust blowing cylinder 32 will rotate accordingly. During the rotation of the blades 323, the resistance of the sector-shaped scraper 23 is further increased, so that the rotation speed of the sector-shaped scraper 23 is further reduced, improving the scraping effect on the waste chips. At the same time, during the rotation of the blades 323, the tiny dust floating in the air will be blown away, preventing the dust from spreading to the vicinity of the drive shaft, thereby causing wear of the drive shaft and further increasing the service life of the drive shaft.
