Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-7 , the present invention provides a technical solution: a CNC high-speed machining center, including a support frame 1, a placement plate 101 is provided on the support frame 1, a chute 102 is provided on the placement plate 101, a high-speed machining body 4 is provided on the support frame 1, an observation window 401 is provided on the high-speed machining body 4, a cleaning and replacement structure 2 is arranged on the support frame 1, and a transmission structure 3 is arranged on the support frame 1;

[0025] The cleaning and replacement structure 2 includes a slide rail 201, a sliding frame 202, a motor 203, a first bevel gear 204, a second bevel gear 205, a rotating gear 206, a rack 207, a fixed frame 208, a moving frame 209, a guide rail 210, a cleaning roller 214, a guide rod 211, a sliding plate 212, and a spring 213. The slide rail 201 is installed on the support frame 1. The sliding frame 202 is slidably installed on the slide rail 201. The motor 203 is installed on the sliding frame 202. The first bevel gear 204 is installed at the driving end of the motor 203. The second bevel gear 205 is movably installed on the sliding frame 202. The rotating gear 206 is movably installed on the sliding frame 202 and the rotating gear 206 is connected to the second bevel gear 205. The rack 207 is installed on the slide rail 201 and the rotating gear 206 meshes with the rack 207. The fixed frame 208 is installed on the sliding frame 202. The moving frame 209 is installed on the fixed frame 208. The guide rail 210 is installed inside the moving frame 209. The guide rod 211 is installed inside the moving frame 209. The sliding plate 212 is movably arranged on the guide rod 211 and the sliding plate 212 is movably connected to the guide rail 210. One end of the spring 213 is installed on the sliding plate 212 and the other end of the spring 213 is connected to the moving frame 209. One end of the cleaning roller 214 is movably installed on the inner wall surface of the moving frame 209 and the other end of the cleaning roller 214 is movably connected to the sliding plate 212. Drive the motor 203. The motor 203 drives the first bevel gear 204 to rotate. Under the action of the first bevel gear 204, the second bevel gear 205 drives the rotating gear 206 to rotate. The rotating gear 206 meshes with the rack 207, and thus the sliding frame 202 can be driven to slide on the slide rail 201. At this time, the moving frame 209 follows the sliding frame 202 to move in the chute 102. The cleaning roller 214 is connected to an external drive and can rotate. The cleaning roller 214 can reciprocate under the action of the moving frame 209 to clean the observation window 401 on the high-speed processing body 4. In the normal state, the spring 213 can drive the sliding plate 212 to abut against one end of the guide rod 211, so that the sliding plate 212 is fixed stably. When it is necessary to replace the cleaning roller 214 for cleaning, move the sliding plate 212. The sliding plate 212 slides on a pair of guide rods 211 through a pair of guide rails 210. At this time, the spring 213 is compressed and the sliding plate 212 moves away from the cleaning roller 214. At this time, the cleaning roller 214 can be removed from the sliding plate 212, which is convenient for replacement. After replacement, one end of the cleaning roller 214 is movably connected to the inner wall surface of the moving frame 209, and the other end of the cleaning roller 214 is movably connected to the sliding plate 212.

[0026] Further, the sliding carriage 202 is adapted to the slide rail 201, and the moving carriage 209 is adapted to the size of the chute 102. The adapted sliding carriage 202 moves more stably on the slide rail 201, and the adapted moving carriage 209 moves more stably in the chute 102.

[0027] Further, there are a pair of guide rails 210, and the guide rails 210 are symmetrically arranged on the inner wall surface of the moving carriage 209. There are a pair of guide rods 211, and the guide rods 211 are symmetrically arranged on the inner wall surface of the moving carriage 209. The two guide rails 210 are respectively movably connected to both ends of the sliding plate 212, making the movement of the sliding plate 212 more stable. The pair of guide rods 211 can support the sliding plate 212 and also guide it, making its sliding more stable.

[0028] Further, the transmission structure 3 includes a placement groove 301, a hydraulic cylinder 302, a moving plate 303, a sleeve 304, a card hole 305, a moving sleeve 306, a limiting hole 307, an installation groove 308, a moving wheel 309, and a limiting pin 310. The placement groove 301 is provided on the support frame 1. The hydraulic cylinder 302 is installed in the placement groove 301. The moving plate 303 is installed at the driving end of the hydraulic cylinder 302. The sleeve 304 is installed on the support frame 1. The card hole 305 is provided on the sleeve 304. The moving sleeve 306 is movably installed in the sleeve 304. The limiting hole 307 is provided on the moving sleeve 306. The installation groove 308 is provided at one end of the moving sleeve 306 away from the sleeve 304. The moving wheel 309 is movably provided in the installation groove 308. The limiting pin 310 is provided in the card hole 305. There are several sets of the sleeve 304, the card hole 305, the moving sleeve 306, the limiting hole 307, the installation groove 308, the moving wheel 309, and the limiting pin 310, which are symmetrically arranged on the lower wall surface of the support frame 1. When the device needs to be moved, the hydraulic cylinder 302 is driven. The hydraulic cylinder 302 drives the moving plate 303 to move. The moving plate 303 contacts the placement plane, and thus the whole device can be lifted. The limiting pin 310 is pulled out of the limiting hole 307 and the card hole 305, and thus the position of the moving sleeve 306 in the sleeve 304 can be adjusted until the moving wheel 309 contacts the placement plane. After adjustment, the limiting pin 310 is inserted into the card hole 305. The limiting pin 310 penetrates through the card hole 305 and the limiting hole 307, and thus the moving sleeve 306 can be fixed in the sleeve 304. The moving plate 303 is retracted, and the whole device can be driven to move by several moving wheels 309. When it moves to the predetermined position, it stops. The hydraulic cylinder 302 is driven again, and the moving plate 303 lifts the device. At this time, the limiting pin 310 is pulled out, the moving wheel 309 is retracted into the sleeve 304, the limiting pin 310 is inserted back to fix the moving sleeve 306, and the moving plate 303 gradually approaches the hydraulic cylinder 302 until several sleeves 304 on the support frame 1 abut against the placement plane. At this time, the moving plate 303 can be retracted, and the device can be stably placed.

[0029] Further, an anti-slip layer is provided on the moving plate 303. The size of the sleeve 304 is adapted to the size of the moving sleeve 306. The anti-slip layer is provided on the end face of the moving plate 303 close to the placement plane. The adapted moving sleeve 306 can stably slide in the sleeve 304.

[0030] Further, the size of the limiting hole 307 is adapted to the size of the limiting pin 310. There are several limiting holes 307. The adapted limiting pins 310 can fix the moving sleeve 306 more stably. The several limiting holes 307 are provided to facilitate the adjustment of the position of the moving sleeve 306.

[0031] Furthermore, a hanging ring is provided on the support frame 1, and the motor 203 is fixed to the sliding frame 202 by bolts. The hanging ring facilitates pulling the entire device to move, and the motor 203 fixed by bolts is convenient for installation and disassembly on the sliding frame 202.

[0032] Working principle: When cleaning is required, the cleaning roller 214 is rotationally connected to an external drive. The motor 203 drives the first bevel gear 204 to rotate. Under the action of the first bevel gear 204, the second bevel gear 205 drives the rotating gear 206 to rotate. The rotating gear 206 meshes with the rack 207, thereby driving the sliding frame 202 to slide on the slide rail 201. At this time, the moving frame 209 follows the sliding frame 202 to move in the chute 102, and the rotating cleaning roller 214 cleans the observation window 401 on the high-speed machining body 4. When the cleaning roller 214 needs to be replaced after a certain amount of cleaning, move the sliding plate 212. The sliding plate 212 moves away from the cleaning roller 214. The sliding plate 212 slides on a pair of guide rods 211 through a pair of guide rails 210. At this time, the spring 213 is compressed until the sliding plate 212 is no longer in contact with the cleaning roller 214. At this time, one end of the cleaning roller 214 can be removed from the sliding plate 212, and the other end can be removed from the moving frame 209, which is convenient for replacement. When the device needs to be moved, drive the hydraulic cylinder 302. The moving plate 303 contacts the placement plane, thereby lifting the entire device. Pull out the limit pin 310 from the limit hole 307 and the locking hole 305, and then the position of the moving sleeve 306 in the sleeve 304 can be adjusted until the moving wheel 309 contacts the placement plane. After adjustment, the limit pin 310 passes through the locking hole 305 and the limit hole 307, thereby fixing the moving sleeve 306 in the sleeve 304. The entire device can be driven to move by several moving wheels 309. Stop when moving to the predetermined position. Drive the hydraulic cylinder 302 again to lift the device. At this time, pull out the limit pin 310, retract the moving wheel 309 into the sleeve 304, and make the moving plate 303 gradually approach the hydraulic cylinder 302 until several sleeves 304 on the support frame 1 abut against the placement plane. At this time, the moving plate 303 can be retracted, and the device can be stably placed.
