Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control machining, in particular to a numerical control gantry machining center. BACKGROUND

[0002] In modern manufacturing, numerical control gantry machining centers are widely used due to their high processing capacity and wide range of applications. It is mainly used in mechanical manufacturing, aerospace, automobile manufacturing and other industries, especially in the production of large parts and complex structures. Numerical control gantry machining center can carry out precise cutting, drilling, milling and other multi-axis machining through numerical control system control, greatly improving production efficiency and machining precision. Metal iron filings are often generated during cutting and other machining processes.

[0003] Therefore, in order to remove the generated impurities, some existing numerical control gantry machining centers have self-cleaning function, for example, a numerical control lathe with cleaning function disclosed in patent application No. CN221232146U, which relates to its technical field, including lathe main body, main body side is equipped with cleaning assembly, the device drives the motor to drive the screw rod to rotate, makes the connecting plate slide along the guide rod, and then drives the scraper to move, pushes the debris in the main body to the discharge chute, and the debris enters the receiving drawer through the chute for centralized treatment, without manual cleaning, convenient and safe, and conducive to improving the neatness of the lathe main body.

[0004] In the actual structural design of numerical control lathe, the main frame will be specially provided with several sliding grooves matched with the motion parts such as tool holder and sliding plate according to the accurate displacement requirement of numerical control machining. These sliding grooves are the motion track of the core transmission assembly. Any iron filings, cutting fluid residues or dust accumulation may directly affect the smoothness of the motion of the parts, even exacerbate the wear of the track, and thus reduce the dimensional accuracy of numerical control machining. Therefore, it is particularly important to keep the cleanliness of the sliding groove.

[0005] The above existing technology can only clean the surface of the lathe main body, and cannot clean the impurities remaining in the sliding groove, so that the tool holder, sliding plate and other parts will contact with the metal iron filings scattered in the sliding groove when moving in the sliding groove, accelerating the wear of the sliding groove and shortening the service life of the lathe main body.

[0006] Based on the above points, the existing numerical control machining method still has room for improvement. SUMMARY

[0007] In order to solve the technical problems existing in the above existing technology, the present application provides a numerical control gantry machining center.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a CNC gantry machining center, including a lathe body, wherein a plurality of sliding grooves are uniformly provided on the top of the lathe body along the width direction.

[0009] The lathe body is equipped with a movable cleaning mechanism, which includes a collection component and a cleaning component.

[0010] The collection component includes a collection frame with an opening facing the direction of movement of the cleaning mechanism, and fixed frames symmetrically arranged on the opening side of the collection frame, with rotating shafts rotatably mounted between the fixed frames.

[0011] Multiple sets of first blades are evenly arranged along the length of the rotating shaft, and second blades that extend into the chute are arranged between adjacent sets of first blades.

[0012] The cleaning assembly includes a first cleaning roller and a second cleaning roller. The surface of the first cleaning roller is a wire mesh structure, and the surface of the second cleaning roller is a cotton cloth structure. Both of them are in contact with the inner wall and bottom of the chute.

[0013] Preferably, the collecting assembly further includes a toggle part, which includes a U-shaped frame disposed on the top of the fixed frame. The horizontal section of the U-shaped frame is provided with mounting brackets that correspond one-to-one with the sliding grooves, and rectangular plates are mounted on the mounting brackets.

[0014] A rectangular plate is symmetrically provided with tensioning plates along the width direction of the lathe body, and the tensioning plates are installed on both sides of the rectangular plate by spring hinges. The two tensioning plates and the rectangular plate form a triangular structure and their free ends abut against each other.

[0015] The frame is equipped with a push cylinder. A horizontal crossbar is installed at the telescopic end of the push cylinder. A vertical rod corresponding to the rectangular plate is installed at the bottom of the horizontal crossbar. The bottom of the vertical rod extends between the two plates. A push rod is installed at the bottom of the vertical rod to push the plates open.

[0016] Preferably, a toggle shaft is rotatably installed at the opening of the collection frame. The toggle shaft is connected to the rotating shaft via belt drive. Multiple toggle blades are evenly arranged on the circumferential surface of the toggle shaft. The toggle blades are used to push the metal scraps conveyed by the first blade and the second blade into the collection frame.

[0017] Preferably, the cleaning assembly further includes a clearance groove formed at the bottom of the collection frame and corresponding to the slide groove, wherein a first rotating shaft is rotatably mounted in the clearance groove via a bearing, and a first cleaning roller is mounted at the bottom of the first rotating shaft.

[0018] The collection frame has a horizontal plate on the side away from the rotating shaft that corresponds to the clearance groove. A second rotating shaft is mounted on the horizontal plate through a bearing. A second cleaning roller is mounted at the bottom of the second rotating shaft. The first rotating shaft and the second rotating shaft are connected by belt drive.

[0019] Preferably, a drive shaft is rotatably mounted on the horizontal plate at the center position via a bearing, and the drive shaft is connected to the corresponding second rotating shaft via belt drive.

[0020] All the second rotating shafts are fitted with sprockets, and the sprockets are connected by chain drive. The drive shaft is used to drive all the second rotating shafts and the first rotating shaft to rotate synchronously.

[0021] Preferably, the collection frame is symmetrically provided with a slidingly connected movable frame on the side away from the rotating shaft along the width direction of the lathe body. The movable frame is uniformly equipped with multiple scrapers along its length, and the scrapers are located between the first cleaning roller and the second cleaning roller. A connecting block is provided at one end of the movable frame near the drive shaft. The connecting block is connected to the first traction rope, and the other end of the first traction rope is wound around the drive shaft. A telescopic spring is installed between the collection frame and the connecting block.

[0022] Preferably, the horizontal plate is provided with an L-shaped reciprocating plate symmetrically along the length direction. The horizontal section of the reciprocating plate slides through the horizontal plate, and an arc plate is installed at its end by a spring hinge. The arc plate is attached to the first cleaning roller and the second cleaning roller.

[0023] The vertical section of the reciprocating plate corresponding to the first cleaning roller is equipped with a linkage rod, and the vertical section of the reciprocating plate corresponding to the second cleaning roller is also equipped with a linkage rod. An elastic telescopic rod that cooperates with the linkage rod is installed on the horizontal plate in the middle position.

[0024] Preferably, the winding shaft is rotatably mounted on the horizontal plate in the central position via a bearing, and the winding shaft is connected to the drive shaft via belt drive.

[0025] A second traction rope is connected to the linkage rod, and the other end of the second traction rope is wound around the winding shaft. The diameter of the winding shaft is smaller than the diameter of the drive shaft.

[0026] Preferably, it also includes a spray pipe for spraying cleaning fluid onto the first cleaning roller, the second cleaning roller and the scraper. The cleaning fluid is used to help remove oil stains and reduce friction between the cleaning components and the slide. Waste liquid generated during cleaning is pushed out of the lathe body by the second cleaning roller.

[0027] Compared with the prior art, the present invention provides a CNC gantry machining center, which has the following beneficial effects:

[0028] (1) The cleaning mechanism achieves all-round collection of metal waste from the lathe body surface and the slide by the cooperation of the first blade, the second blade and the actuating part. The first blade scrapes the flaky and granular metal waste from the surface, and the second blade goes deep into the slide to stir the blocky metal waste and transport it through the guide plate. The guide plate can also scrape the fine metal waste from the slide wall at the same time. In response to the problem of metal waste overflowing from the top of the slide, the opening and closing plate of the actuating part can push it to the surface to avoid excessive accumulation of metal waste in the slide and causing the second blade to jam. The actuating shaft of the collection frame opening cooperates with the actuating blade to force the metal waste to fall into the collection frame and prevent it from circulating with the first blade and the second blade, which greatly improves the collection stability and efficiency.

[0029] (2) A multi-level cleaning system is formed by the first cleaning roller, the second cleaning roller, and the scraper to effectively handle oil stains and residual impurities. The wire mesh structure of the first cleaning roller removes stubborn oil stains and small metal scraps from the inner wall of the chute through friction. The cotton cloth structure of the second cleaning roller performs secondary cleaning, which, together with the cleaning liquid from the spray pipe, reduces friction and enhances the degreasing effect. The scraper can scrape off oil stains on the lathe surface, and its position is between the two cleaning rollers to ensure that the scraped impurities and waste liquid can be discharged into the chute in time and pushed out by the second cleaning roller, achieving comprehensive cleaning from the surface to the inside of the chute and avoiding oil stain residue from affecting the operation of the equipment.

[0030] (3) By using differentiated shaft diameters and linkage structures, the synchronous and precise operation of each component is ensured. That is, the diameter of the winding shaft is much smaller than that of the drive shaft, ensuring that the scraper and linkage rod arrive at the working position synchronously and eliminating position deviation. When the arc plate moves with the reciprocating plate, it always comes into contact with the cleaning roller and scrapes off the surface impurities to avoid secondary pollution.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0046] This embodiment proposes a CNC gantry machining center, such as Figures 1-12 As shown, the lathe body 1 is equipped with a CNC device, a drive device, an auxiliary device and a programming device. Multiple slide grooves 11 are evenly arranged on the top of the lathe body 1 along its width direction.

[0047] The lathe body 1 is also equipped with a cleaning mechanism 2 for cleaning it. Figure 1 The arrow indicates the direction of movement of the cleaning mechanism 2. The cleaning mechanism 2 includes a collection component 21 for collecting metal scraps on the lathe body 1 and a cleaning component 22 for cleaning oil stains and oil-adhered impurities on the lathe body 1.

[0048] It should be explained that, in order to facilitate understanding of the technical solution of this application, the CNC device, drive device, auxiliary device and programming device provided in this application are not shown in the figure, only the lathe body 1 and the cleaning mechanism 2 are shown.

[0049] The collection component 21 includes a collection frame 211 with its opening facing the moving direction of the cleaning mechanism 2. A fixing frame 212 is symmetrically installed on the opening side of the collection frame 211 along its length direction. A rotating shaft 213 is rotatably installed between the fixing frames 212 via bearings. Multiple sets of first blades 214 for collecting metal scrap from the surface of the lathe body 1 are evenly arranged on the rotating shaft 213 along its length direction, and each set of first blades 214 is evenly distributed circumferentially along the circumferential surface of the rotating shaft 213.

[0050] A second blade 215 is provided between each group of first blades 214 to cooperate with the chute 11 and extend into the chute 11. Multiple second blades 215 are provided between each group of first blades 214 and are evenly distributed circumferentially along the circumferential surface of the rotation axis 213. Multiple guide plates 216 are provided at the bottom of the collection frame 211 to cooperate with the chute 11 and are inclined. During the rotation of the second blades 215, the metal scraps in the chute 11 can be moved and collected, and the metal scraps can be transported into the collection frame 211 along the inclined direction of the guide plates 216.

[0051] It should be noted that the power sources that drive the cleaning mechanism 2 to move, dock, or perform cleaning actions, such as manual pushing, cylinder piston rod extension and retraction, motor output shaft driving gears, and lead screw rotation, are all existing well-known technologies that are widely used in the field of mechanical design. When describing the driving force in the following content, the specific installation position of the driving force source, the connection method with the cleaning mechanism 2, and the power transmission path will not be elaborated. Only the result of the action will be briefly described.

[0052] Accordingly, the specific structures of the cylinders and motors, etc., driving force sources, will no longer be drawn separately in the accompanying drawings of the instruction manual (except for special cases).

[0053] In specific operations, when the lathe body 1 needs to be cleaned, the cleaning mechanism 2 is placed on the lathe body 1, and each set of blades is aligned with the corresponding slide groove 11. At this time, the existing drive cylinder pushes the collection frame 211 to move. During the movement of the collection frame 211, the drive motor drives the rotating shaft 213 to rotate. During the rotation of the rotating shaft 213, the first blade 214 can be rotated. During the rotation of the first blade 214, its edge will be in close contact with the surface of the lathe body 1, scraping and conveying the flaky and granular metal waste remaining on the surface after processing. Finally, the waste is guided to fall into the collection frame 211 along the rotation trajectory of the first blade 214, completing the initial collection of surface waste.

[0054] At this time, the second blade 215 rotates synchronously. The second blade 215, which is deep inside the chute 11, rotates along the inner wall of the chute 11 under the drive of the rotating shaft 213, which can stir up the blocky metal scraps accumulated at the bottom and side walls of the chute 11 and transport them outward.

[0055] Meanwhile, the guide plate 216 that is in contact with the chute 11 will move synchronously with the collection frame 211, and the waste material conveyed by the second blade 215 will slide into the collection frame 211 along the inclined direction of the guide plate 216, so as to prevent the waste material from falling or accumulating in the chute 11.

[0056] During this process, the rotating shaft 213 collects metal scrap from the surface of the lathe body 1 and the inside of the slide 11 through the cooperation of the first blade 214 and the second blade 215, covering both the visible surface area of ​​the lathe body 1 and the inside of the narrow slide 11 of the lathe body 1.

[0057] It should be noted that, in addition to guiding the metal scraps, the guide plate 216 can also scrape the trace metal scraps remaining inside the chute 11 as it moves with the collection frame 211, thoroughly removing the trace metal scraps adhering to the inner wall of the chute 11, ensuring that there are no scraps left inside the chute 11. The scraped trace metal scraps fall into the chute 11 and move synchronously with the guide plate 216, further improving the thoroughness of cleaning.

[0058] The rotating first blade 214 can collect metal scraps from the surface of the lathe body 1 into the collection frame 211. The second blade 215 can collect metal scraps from inside the slide 11 into the collection frame 211 via the guide plate 216. Then, the rotating shaft 213 can collect metal scraps on the lathe body 1 through the cooperation of the first blade 214 and the second blade 215. The guide plate 216 and the slide 11 can simultaneously scrape off the small metal scraps remaining inside the slide 11.

[0059] During the machining process on a CNC lathe, metal scraps are continuously generated and fall into the slide 11. Since the slide 11 itself is a long and narrow structure with limited internal space, the scraps will first gradually accumulate at the bottom of the slide 11. As the amount of scraps increases, the accumulation height will continue to rise until it fills the effective space inside the slide 11.

[0060] When the inside of the slide 11 is completely filled with metal scraps, the scraps generated later will overflow to the top of the slide 11 due to lack of space, forming an additional accumulation in the slide 11 and the surrounding area. Eventually, the inside of the slide 11 is filled with metal scraps and overflows, which causes the metal scraps filled inside the slide 11 to squeeze each other and compact the metal scraps. The second blade 215 needs to overcome a large amount of scrap resistance to move it during the turning process, which can easily cause the metal scraps to get stuck on the rotation path of the second blade 215 and not be able to move smoothly out of the inside of the slide 11.

[0061] The actuating part 23 provided in this application can push the overflowing and accumulated metal scraps at the top of the slide 11 to both sides, reducing the possibility of metal scraps entering the interior of the slide 11. Specifically, the actuating part 23 includes a U-shaped frame 231 set on the top of the fixed frame 212 with the opening facing downward. The two vertical sections of the U-shaped frame 231 are respectively installed on the fixed frame 212 on the corresponding sides. The horizontal section of the U-shaped frame 231 is equipped with mounting brackets 232 that correspond one-to-one with the slide 11. A rectangular plate 233 is installed on the mounting bracket 232. A tensioning plate 234 is symmetrically arranged on the rectangular plate 233 along the width direction of the lathe body 1, and the tensioning plate 234 is installed on both sides of the rectangular plate 233 by spring hinges.

[0062] Two laminated plates 234 and rectangular plate 233 form a triangular structure, with the sides of the laminated plates 234 away from the spring hinge abutting against each other. A push cylinder 235 is installed on the horizontal section of the frame 231 via a cylinder seat. A horizontal crossbar 236 is installed at the telescopic end of the push cylinder 235. A vertical bar 237 corresponding to the rectangular plate 233 is installed at the bottom of the horizontal crossbar 236. The bottom of the vertical bar 237 extends between the two laminated plates 234. A push rod 238 for pushing the laminated plates 234 to open is installed at the bottom of the vertical bar 237.

[0063] In specific operation, the fixed frame 212 moves synchronously with the convex frame 231. During the movement of the convex frame 231, the mounting frame 232 drives the rectangular plate 233 to move synchronously. At this time, the triangular structure formed by the rectangular plate 233 and the tension plate 234 can push the metal scrap overflowing from the top of the slide 11 to both sides, so that the metal scrap moves to the surface of the lathe body 1. At this time, the push cylinder 235 is started synchronously. When the extension end of the push cylinder 235 is pushed in the direction of the collection frame 211, the horizontal crossbar 236 and the vertical bar 237 cooperate to drive the push rod 238 to move synchronously. During the movement of the push rod 238, it can abut against the tension plate 234 and make the tension plate 234 open around the spring hinge.

[0064] During the opening process of the tension plate 234, the metal scraps are actively pushed to both sides. When the extension end of the push cylinder 235 is reset, the push rod 238 is reset simultaneously, and the tension plate 234 is reset simultaneously under the action of the spring hinge. Repeating the above actions can move the metal scraps accumulated on the top of the slide 11 to both sides.

[0065] Furthermore, since the rotation space of the first blade 214 is much larger than that of the second blade 215, the first blade 214 does not have the blockage defect of the second blade 215 when it moves and transports the excess metal scraps moved by the tension plate 234.

[0066] The collection frame 211 opening is also equipped with a rotating actuating shaft 217 via a bearing. The actuating shaft 217 is connected to the rotating shaft 213 by a belt drive (not shown in the figure). Multiple actuating blades 218 are evenly arranged on the circumferential surface of the actuating shaft 217. When the first blade 214 and the second blade 215 transport metal impurities to the vicinity of the opening of the collection frame 211, the rotating actuating blades 218 can directly apply a thrust toward the inside of the collection frame 211 to these impurities.

[0067] The thrust can unload metal scraps from the first blade 214 and the second blade 215, thereby preventing impurities from following the first blade 214 and the second blade 215 in a cyclical motion due to inertia or adhesion, and ensuring that the metal scraps can be collected stably and efficiently.

[0068] For lubrication, lubricating oil is often applied to the lathe body 1. Over time, impurities will adhere to the lubricating oil. Therefore, after the larger metal scraps are completely collected, the impurities adhering to the lathe body 1 need to be cleaned by the cleaning component 22. Specifically, the cleaning component 22 includes a relief groove 221 at the bottom of the collection frame 211 and corresponding to the slide groove 11. A first rotating shaft 222 is installed inside the relief groove 221 through a bearing. A first cleaning roller 223 is installed at the bottom of the first rotating shaft 222. A horizontal plate 224 corresponding to the relief groove 221 is installed on the side of the collection frame 211 away from the rotating shaft 213. A second rotating shaft 225 is rotatably mounted on the horizontal plate 224 through a bearing. A second cleaning roller 226 is installed at the bottom of the second rotating shaft 225. The first rotating shaft 222 and the second rotating shaft 225 are connected by a belt drive.

[0069] A drive shaft 227 is mounted on the central horizontal plate 224 via bearings. The drive shaft 227 is also connected to the second rotating shaft 225 on the corresponding horizontal plate 224 via belt drive. A sprocket 228 is mounted on the second rotating shaft 225. Before operation, all sprockets 228 are connected via chain drive.

[0070] The surface of the first cleaning roller 223 is provided with a wire mesh structure, and the surface of the second cleaning roller 226 is provided with a cotton cloth structure. The circumferential surfaces of the first cleaning roller 223 and the second cleaning roller 226 are in contact with the inner sidewall of the chute 11, and the bottoms of the first cleaning roller 223 and the second cleaning roller 226 are in contact with the bottom of the chute 11. In specific operation, the output shaft of the existing drive motor drives the drive shaft 227 to rotate through belt drive. During the rotation of the drive shaft 227, the corresponding second rotating shaft 225 is driven to rotate through belt drive. During the rotation of the second rotating shaft 225, the remaining second rotating shaft 225 is driven to rotate through sprocket 228 and chain drive. During the rotation of the second rotating shaft 225, the corresponding first rotating shaft 222 is driven to rotate through belt drive.

[0071] Furthermore, during the rotation of the first rotating shaft 222, the first cleaning roller 223 is driven to rotate synchronously. During the rotation of the first cleaning roller 223, the stubborn oil stains and small metal scraps adhering to the inner wall of the chute 11 can be rubbed and cleaned through the wire mesh structure. During the rotation of the second rotating shaft 225, the second cleaning roller 226 is driven to rotate synchronously. During the rotation of the second cleaning roller 226, the chute 11 after being cleaned by the wire mesh structure can be cleaned a second time through the cotton cloth structure to remove the fine scraps and other debris that were not cleaned by the wire mesh structure.

[0072] It should be noted that during the rotation of the first cleaning roller 223 and the second cleaning roller 226, cleaning liquid is sprayed onto the circumferential sidewalls of the two rollers through the existing spray pipe (not shown in the figure). This reduces the friction between the first cleaning roller 223 and the second cleaning roller 226 and the inner wall of the chute 11, while also cleaning the oil stains. The waste liquid after cleaning moves in the direction of the collection frame 211 inside the chute 11 under the drive of the second cleaning roller 226 and the cotton cloth structure until the waste liquid and impurities are discharged outside the lathe body 1.

[0073] The scraper 31 provided in this application can also clean oil stains and impurities on the surface of the lathe body 1. Specifically, a movable frame 3 is symmetrically arranged along the width direction of the lathe body 1 on the side of the collection frame 211 away from the rotating shaft 213, and the movable frame 3 is slidably arranged on the collection frame 211. Multiple scrapers 31 are evenly installed on the movable frame 3 along its length direction. The scrapers 31 are used to scrape off oil stains and impurities on the surface of the lathe body 1. A connecting block 32 is provided at the end of the movable frame 3 near the drive shaft 227. A first traction rope 33 is provided on the connecting block 32. The end of the first traction rope 33 away from the connecting block 32 is wrapped around the drive shaft 227. A fixing protrusion is provided on the part of the collection frame 211 located between the two movable frames 3. A telescopic spring 34 for resetting the connecting block 32 is installed between the fixing protrusion and the corresponding connecting block 32.

[0074] During operation, the drive shaft 227 rotates and winds the first traction rope 33. At this time, the first traction rope 33 tightens and drives the moving frame 3 to move towards each other through the connecting block 32. During the movement of the moving frame 3 towards each other, the scraper 31 is driven to scrape off the oil stains and impurities on the surface of the lathe body 1. The scraped impurities fall into the corresponding slide groove 11. At this time, the telescopic spring 34 is compressed. When the first traction rope 33 is completely wound, the drive shaft 227 rotates back, the telescopic spring 34 opens and drives the scraper 31 to reset through the cooperation of the connecting block 32 and the moving frame 3. Repeating the above actions can drive the scraper 31 to clean the oil stains and impurities on the surface of the lathe body 1. During this process, cleaning liquid is also sprayed onto the surface of the scraper 31 through the spray pipe to further improve the cleaning effect of the scraper 31.

[0075] It should be noted that the scraper 31 is positioned between the first cleaning roller 223 and the second cleaning roller 226 in the length direction of the lathe body 1, so as to ensure that the impurities and waste liquid scraped by the scraper 31 can be discharged into the corresponding chute 11 in a timely manner, and pushed outward by the second cleaning roller 226 and the cotton cloth structure.

[0076] A reciprocating plate 4 with an L-shaped structure is symmetrically arranged on the horizontal plate 224 along its length direction. The horizontal section of the reciprocating plate 4 is slidably arranged on the horizontal plate 224. An arc plate 41 is installed at the end of the horizontal section of the reciprocating plate 4 through a spring hinge, and the arc plate 41 is attached to the first cleaning roller 223 and the second cleaning roller 226 on the corresponding side.

[0077] The vertical ends of the reciprocating plates 4 corresponding to the first cleaning roller 223 are all equipped with linkage rods 42. The vertical ends of the reciprocating plates 4 corresponding to the second cleaning roller 226 are also equipped with linkage rods 42. The linkage rods 42 all pass through the corresponding scrapers 31. The horizontal plate 224 in the middle position is equipped with elastic telescopic rods 43 corresponding to the linkage rods 42 through rectangular protrusions. The telescopic ends of the elastic telescopic rods 43 are connected to the corresponding linkage rods 42. The horizontal plate 224 in the middle position and located between the two linkage rods 42 is equipped with a winding shaft 44 through a bearing. The linkage rods 42 are provided with second traction ropes 45. The end of the second traction rope 45 away from the corresponding linkage rod 42 is wound around the winding shaft 44. The winding shaft 44 and the drive shaft 227 are connected by belt drive.

[0078] Since the working stroke of the scraper 31 is significantly greater than the movement stroke of the linkage rod 42, the diameter of the winding shaft 44 is much smaller than the diameter of the drive shaft 227. This ensures that when the drive shaft 227 and the winding shaft 44 rotate the same number of times, their linear displacement (i.e., circumference multiplied by the number of rotations) can accurately compensate for the stroke difference between the scraper 31 and the linkage rod 42. In other words, the drive shaft 227, with its larger diameter, generates a longer linear displacement, which can drive the scraper 31 to complete a long-distance movement. Meanwhile, the winding shaft 44 outputs a shorter linear displacement with a smaller diameter to match the linkage rod 42. Ultimately, this ensures that the linkage rod 42 and the scraper 31 arrive at the preset working position simultaneously, thereby reducing the positional deviation that may be caused by the stroke difference and avoiding the possibility that the linkage rod 42 arrives at the preset working position while the scraper 31 does not.

[0079] In actual operation, the drive shaft 227 rotates and drives the winding shaft 44 to rotate via belt drive. During the rotation of the winding shaft 44, the second traction rope 45 is wound and tightened. During the tightening of the second traction rope 45, the linkage rod 42 moves synchronously in opposite directions. During the movement of the linkage rod 42, the reciprocating plate 4 moves synchronously. At this time, the elastic telescopic rod 43 is stretched. During the movement of the reciprocating plate 4 in opposite directions, the corresponding arc plate 41 is driven to gradually move away from the first cleaning roller 223 and the second cleaning roller 226.

[0080] During this process, the angle of the arc plate 41 on the same side gradually decreases under the action of the spring hinge. As the angle of the arc plate 41 decreases, the side of the arc plate 41 away from the spring hinge is always in contact with the first cleaning roller 223 and the second cleaning roller 226. During this process, the side of the arc plate 41 away from the spring hinge can move and scrape off the impurities adhering to the circumference of the first cleaning roller 223 and the second cleaning roller 226, and clean the surface of the first cleaning roller 223 and the second cleaning roller 226 to avoid secondary pollution of the inside of the slide 11 by the impurities adhering to the first cleaning roller 223 and the second cleaning roller 226. The scraped impurities fall into the inside of the slide 11 and move towards the collection frame 211 inside the slide 11 under the drive of the second cleaning roller 226 and the cotton cloth structure until the waste liquid and impurities are discharged outside the lathe body 1.

[0081] After cleaning the lathe body 1, the cleaning mechanism 2 can be removed.

[0082] The working principle of this application is as follows: The top of the lathe body 1 is provided with multiple slide grooves 11 and a cleaning mechanism 2 is provided. The cleaning mechanism 2 can move along the slide groove 11 and includes a collection component 21 for collecting metal scrap and a cleaning component 22 for cleaning oil and impurities, so as to realize all-round automated cleaning of the surface of the lathe body 1 and the inside of the slide groove 11.

[0083] The rotating shaft 213 has multiple sets of first blades 214 on its surface, which are used to scrape the waste on the surface of the lathe body 1. A second blade 215 is provided between adjacent sets of first blades 214, which can penetrate into the slide groove 11 to move the metal waste inside the slide groove 11. An inclined guide plate 216 is provided at the bottom of the collection frame 211. The second blade 215 pushes the waste along the guide plate 216 into the collection frame 211.

[0084] The guide plate 216 can also scrape off residual metal scraps on the inner wall of the chute 11. To address the problem of easy blockage in the chute 11, the cylinder pushes the opening and closing plate 234 to push the overflowing metal scraps from the top of the chute 11 to both sides, avoiding blockage of the second blade 215. A toggle shaft 217 and blades are also provided to ensure that the metal scraps are detached from the first blade 214 and the second blade 215 due to inertia, so that the metal scraps fall stably into the collection frame 211.

[0085] The cleaning component 22 targets impurities adhering to the lubricating oil and includes a first cleaning roller 223 (steel wire mesh structure) and a second cleaning roller 226 (cotton cloth structure). The first cleaning roller 223 and the second cleaning roller 226 are linked by belt drive and chain drive and are driven by the drive shaft 227. When the first cleaning roller 223 rotates, it rubs against the inner wall of the slide groove 11 to remove stubborn oil stains and fine metal scraps. The second cleaning roller 226 performs secondary fine cleaning. During the cleaning process, cleaning liquid is sprayed to assist in the removal of dirt. The waste liquid is pushed to the outside of the lathe body 1 by the second cleaning roller 226. At the same time, the scraper 31 moves in opposite directions controlled by the first traction rope 33 to scrape off the oil stains on the surface of the lathe body 1. The scraped impurities are discharged into the slide groove 11 and then processed by the second cleaning roller 226. The position of the scraper 31 cooperates with the first cleaning roller 223 and the second cleaning roller 226 to ensure that the impurities are removed in a timely manner.

[0086] The arc plate 41 on the reciprocating plate 4 is controlled by the second traction rope 45. When the first cleaning roller 223 and the second cleaning roller 226 are working, they periodically scrape off the impurities adhering to their surface to prevent secondary pollution. The design of the diameter difference between the drive shaft 227 and the winding shaft 44 accurately compensates for the stroke difference between the scraper 31 and the linkage rod 42 to ensure synchronous action. Finally, the cleaning mechanism 2 can be removed after cleaning is completed.
