Description

Technical Field

[0001] This application relates to the field of guide rail cleaning technology, and in particular to a guide rail cleaning device for CNC lathes. Background Technology

[0002] CNC lathe guideways are core components that guide the precise movement of moving parts such as the tool post and worktable. They are widely used in the field of machining and are directly related to the dimensional accuracy and surface quality of the workpiece. They are a key guarantee for CNC lathes to achieve efficient and precise machining.

[0003] During the machining process, CNC lathes generate impurities such as iron filings, oil stains, and dust. These impurities adhere to the surface of the guide rails, and if they are not cleaned in time, they will affect the normal operation of the guide rails.

[0004] In the prior art, the tool holder slides on the guide rail to support the movement of the tool on the tool holder. When the tool holder slides on the guide rail, if impurities are not cleaned beforehand, the following defects exist:

[0005] First, impurities can easily get embedded in the gap between the tool holder and the guide rail, causing severe friction when the two move relative to each other, resulting in scratches on the guide rail surface or wear on the tool holder.

[0006] Secondly, the accumulation of impurities over a long period of time will increase the resistance to movement, reduce the accuracy of the tool holder movement, and affect the machining accuracy of the workpiece.

[0007] Third, hard impurities may cause tool holder jamming, or even overload the drive system, shorten the service life of the equipment, and increase maintenance costs.

[0008] Therefore, those skilled in the art have provided a CNC lathe guideway cleaning device to solve the problems mentioned in the background art. Utility Model Content

[0009] To address the problems mentioned in the background art, this application provides a CNC lathe guideway cleaning device.

[0010] The CNC lathe guideway cleaning device provided in this application adopts the following technical solution:

[0011] A CNC lathe guide rail cleaning device includes a guide rail and a tool holder slidably mounted on the guide rail. Scrapers are detachably mounted on both ends of the tool holder. The scrapers are slidably connected to the outer surface of the tool holder. A baffle is fixed to the inner side of each of the two tool holders. One end of each baffle is respectively attached to the two sides of the guide rail. A notch is provided through the bottom end of the scraper. The scraper is slidably inserted into a mounting base. Several flexible bristles extending into the notch are fixed to the bottom end of the mounting base. A heat dissipation fan blade located on one side of the notch is rotatably arranged inside the baffle.

[0012] In this invention, the baffle covers the area between the end of the blade holder and the scraper, which not only prevents impurities from splashing during the cleaning process, but also provides a stable working space for the cooling fan blades. At the same time, the cooperation between the scraper and the baffle forms all-round protection for the guide rail, further improving the safety of equipment operation.

[0013] Preferably, a fixing plate is fixed to the upper end of the mounting base, and a screw is threadedly connected to the fixing plate and the scraper. The end of the screw is threadedly connected to the tool holder.

[0014] Preferably, the scraper has an installation groove communicating with the notch, the mounting seat is slidably inserted into the installation groove, and the two sides of the scraper are in contact with the outer wall of the guide rail.

[0015] Preferably, the cooling fan blades are fixed with a rotating shaft, and the rotating shaft is rotatably connected to the baffle.

[0016] In this invention, the number of rotating shafts and cooling fan blades can be set to 3-4, and the rotating shafts and rotating rods are connected by toothed belts to improve the airflow rate inside the baffle.

[0017] Preferably, a rotating rod is rotatably connected to one side of the baffle, a friction roller is fixed at the bottom end of the rotating rod, the friction roller is in rolling connection with the side wall of the guide rail, and a toothed belt is fixed between the rotating rod and the outer wall of the rotating shaft.

[0018] In this invention, the toothed belt can be replaced by a chain to improve the transmission effect between the rotating rod and the rotating shaft.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] ① The scrapers at both ends of the tool holder move with the tool holder, which can first scrape away impurities on both sides of the guide rail. At the same time, the scrapers drive the flexible bristles to clean the impurities on the upper surface of the guide rail, thoroughly removing iron filings, dust and other contaminants from the guide rail. This prevents equipment damage caused by friction between the tool holder and the guide rail, and extends the service life of the guide rail and the tool holder.

[0021] ② The cooling fan blades inside the baffle can rotate synchronously with the movement of the cutter holder and scraper, which accelerates the air exchange between the inside of the baffle and the outside through the gap, effectively reducing the temperature between the baffle and the end of the cutter holder, and preventing excessive heat from affecting the performance of the equipment or causing the components to age.

[0022] ③ When cleaning impurities using a scraper and flexible bristles, the friction rollers rotate, and the cooling fan blades rotate through a transmission structure such as a rotating rod and toothed belt, so that the cleaning action and the heat dissipation function are linked, achieving a dual effect without additional power.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-3 As shown, this application discloses a CNC lathe guideway cleaning device, including a guideway 1 and a tool holder 2 slidably mounted on the guideway 1. Scrapers 3 are detachably mounted on both ends of the tool holder 2, and the scrapers 3 are slidably connected to the outer surface of the tool holder 2. A baffle 4 is fixed to the inner side of each of the two tool holders 2, and one end of each baffle 4 is respectively attached to both sides of the guideway 1. A notch 15 is provided through the bottom end of the scraper 3, and a mounting base 6 is slidably inserted into the scraper 3. Several flexible bristles 7 extending into the notch 15 are fixed to the bottom end of the mounting base 6. A heat dissipation fan blade 9 is rotatably mounted inside the baffle 4 on one side of the notch 15. By installing scrapers 3 at both ends of the tool holder 2 and by setting baffles 4 between the scrapers 3 and the ends of the tool holder 2... The baffle 4 surrounds the end of the cutter holder 2 and the scraper 3. During the movement of the cutter holder 2, the two scrapers 3 can scrape away the impurities on both sides of the guide rail 1 in the direction of the cutter holder 2's movement. The movement of the scraper 3 drives the flexible bristles 7 to clean the impurities on the upper surface of the guide rail 1. This avoids friction damage between the cutter holder 2 and the guide rail 1 due to impurities during the movement. In addition, a rotatable heat dissipation fan 9 is set inside the baffle 4. When the cutter holder 2 and the scraper 3 are cleaning impurities during the movement, the rotation of the heat dissipation fan 9 can accelerate the flow of air inside the baffle 4 from the notch 15 to exchange heat with the outside, so as to dissipate heat and cool down the scraper 3 and the end of the cutter holder 2, and prevent the heat between the scraper 3 and the end of the cutter holder 2 from being too high.

[0029] In this embodiment, a method for driving the cooling fan blade 9 to rotate is provided. The cooling fan blade 9 is fixed with a rotating shaft 10, which is rotatably connected to the baffle 4. A rotating rod 14 is rotatably connected to one side of the baffle 4. A friction roller 13 is fixed at the bottom of the rotating rod 14 and is rotatably connected to the side wall of the guide rail 1. A toothed belt 12 is fixed between the rotating rod 14 and the outer wall of the rotating shaft 10. When the scraper 3 and the flexible bristles 7 move with the blade holder 2 to clean impurities on the guide rail 1, the friction roller 13 at the bottom of the rotating rod 14 is driven to roll and rotate along the length of the guide rail 1, causing the rotating rod 14 to rotate. Under the action of the toothed belt 12, the rotating shaft 10 is driven to rotate, driving the cooling fan blade 9 to rotate. This accelerates the airflow inside the baffle 4 and exchanges heat with the outside air through the gap 15, thus cooling the air.

[0030] A fixing plate 8 is fixed to the upper end of the mounting base 6. The fixing plate 8 and the scraper 3 are threadedly connected to a screw 5. The end of the screw 5 is threadedly connected to the blade holder 2. The screw 5 enables the scraper 3 and the baffle 4 to be installed at one end of the blade holder 2, and the mounting base 6 to be installed inside the notch 15 to support the flexible bristles 7.

[0031] The scraper 3 has an installation groove 11 that communicates with the notch 15. The mounting seat 6 is slidably inserted into the installation groove 11. The two sides of the scraper 3 are in contact with the outer wall of the guide rail 1. By rotating the disassembly screw 5 to disengage from the knife holder 2 and the fixing plate 8, the scraper 3 and the baffle 4 can be moved away from the knife holder 2 and the guide rail 1 for disassembly. This allows for the lubrication and maintenance of the guide rail 1. In addition, the fixing plate 8 can be moved to disengage the mounting seat 6 from the installation groove 11, allowing the flexible bristles 7 to be disassembled and replaced.

[0032] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: By installing scrapers 3 at both ends of the cutter holder 2, and by setting a baffle 4 between the scraper 3 and the end of the cutter holder 2 to surround the end of the cutter holder 2 and the scraper 3, during the movement of the cutter holder 2, the two scrapers 3 can scrape away the impurities on both sides of the guide rail 1 in the forward direction of the cutter holder 2. The movement of the scraper 3 drives the flexible bristles 7 to clean the impurities on the upper surface of the guide rail 1. This avoids the friction damage caused by impurities between the cutter holder 2 and the guide rail 1 during the movement. When the scraper 3 and the flexible bristles 7 move with the forward direction of the cutter holder 2 to clean the impurities on the guide rail 1, the friction roller 13 at the bottom of the rotating rod 14 rolls and rotates along the length of the guide rail 1, causing the rotating rod 14 to rotate. Under the action of the toothed belt 12, the rotating shaft 10 rotates, driving the cooling fan blades 9 to rotate, accelerating the airflow inside the baffle 4 to exchange heat with the outside air through the gap 15, and thus cooling down.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
