Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool guideway protection, specifically, to a guideway protective cover for machine tools. Background Technology

[0002] CNC machine tool guideway protective covers are used to protect machine tool equipment, specifically the guideways and lead screws, from external corrosion and damage. In particular, coolant and machining debris used during processing can penetrate the machine tool and damage the guideways and lead screws, affecting the machine tool's lifespan and accuracy. The purpose of machine tool guideway protective covers is to prevent coolant and machining debris from entering the machine tool and damaging the guideways and lead screws. However, existing machine tool guideway protective covers often have gaps between any two covers, allowing debris or cutting fluid to enter the machine tool and damage the guideways or lead screws. Furthermore, existing technologies use scraper blades between the guideway covers, but commonly used scraper blades use rubber scrapers that adhere to the cover surface to seal the gaps between the covers. However, after prolonged immersion in coolant and machining debris, and due to wear and tear, the rubber scraper blades can age, break, and become less effective at sealing. Additionally, high-temperature debris can burn the rubber, and metal debris can cut the rubber during the compression process of each cover section, affecting the sealing effect. Summary of the Invention

[0003] Therefore, it is necessary to address the problems in the existing technology where gaps exist between adjacent machine tool guideway protective covers, allowing chips or coolant to enter the machine tool interior, and where the scraper plates used in the existing technology are made of rubber and are prone to aging and wear. A new machine tool guideway protective cover is provided where a scraper structure is installed between any two adjacent covers to seal and scrape chips. Furthermore, the scraper plates are made of metal to prevent aging or wear.

[0004] A guide rail protective cover includes several covers connected by a telescopic mechanism. The cover is characterized by a scraping structure positioned between any two adjacent covers. When the telescopic mechanism extends or retracts the covers, the scraping structure scrapes off chips from the covers. The scraping structure includes a scraper tongue positioned between two adjacent covers. The scraper tongue has a fixed end and a scraping end, with an obtuse angle between the fixed end and the scraping end. The fixed end of the scraper tongue is fixed between two covers and is also fixed to the rear cover. The scraping end of the scraper tongue is fastened to the upper surface of the front cover and abuts against the upper surface of the front cover.

[0005] Furthermore, an upper pressure plate is provided between the scraper tongue and the rear end cover. The shape of the upper pressure plate matches the shape of the scraper tongue. One end of the upper pressure plate is located between the fixed end of the scraper tongue and the rear end cover, and the free end of the upper pressure plate presses on the scraping end of the scraper tongue.

[0006] Furthermore, a brass base plate is provided between the fixed end of the scraper tongue and the front end cover.

[0007] Furthermore, the scraper is made of metal.

[0008] Furthermore, the scraping end of the scraper tongue uses a spring steel sheet.

[0009] Furthermore, the thickness of the spring steel sheet is 0.1mm to 0.2mm.

[0010] Furthermore, each of the bottom locking blocks is provided with a locking buckle at its upper end.

[0011] Furthermore, the rear end cover, upper pressure plate, scraper tongue, and brass base plate are connected from top to bottom by bolts.

[0012] This utility model provides a guide rail protective cover, in which a scraper tongue is provided between any two adjacent covers. The angle between the fixed end and the scraping end of the scraper tongue is obtuse. The scraper tongue is fastened to the upper surface of the front cover, with its scraping end abutting against the upper surface of the front cover. When the cover extends or retracts, it scrapes the chips and coolant on the upper surface of the front cover to the front and discharges them, thereby preventing chips and coolant from entering the cover and damaging the guide rail or lead screw. In addition, the scraper tongue in this utility model is made of metal, thereby preventing the scraper tongue from aging or wearing out and ensuring a sealing effect. Attached Figure Description

[0017] This utility model provides a guide rail protective cover, which includes several protective covers connected by a telescopic mechanism. A scraping structure is provided between any two adjacent protective covers. When the telescopic mechanism drives each of the protective covers to extend or retract, the scraping mechanism scrapes off the chips on the protective covers. The scraping structure includes a scraper tongue disposed between adjacent protective covers. The scraper tongue includes a fixed end and a scraping end. The angle between the fixed end and the scraping end is an obtuse angle. The fixed end of the scraper tongue is fixed between two protective covers, and the scraping end of the scraper tongue is fastened to the upper surface of the front protective cover and abuts against the upper surface of the front protective cover.

[0018] This utility model provides a guide rail protective cover, in which a scraper tongue is provided between any two adjacent covers. The angle between the fixed end of the scraper tongue and the scraping end is an obtuse angle. The scraper tongue is fastened to the upper surface of the front cover, and its scraping end abuts against the upper surface of the front cover. When the cover extends or retracts, it scrapes the chips and coolant on the upper surface of the front cover to the front end for discharge, thereby preventing chips and coolant from entering the interior of the cover and damaging the guide rail or lead screw.

[0019] The following description, in conjunction with specific embodiments, illustrates a guide rail protective cover to further illustrate the inventive concept of the guide rail protective cover.

[0020] In one embodiment, such as Figure 1-5As shown, the guide rail protective cover includes several protective covers 1, which are connected by a telescopic mechanism 2. The telescopic mechanism 2 extends or shortens the protective covers 1. A scraping structure 3 is provided between any two adjacent protective covers 1. When the telescopic mechanism 2 extends or shortens each protective cover 1, the scraping structure 3 scrapes off the chips on the protective covers 1. The scraping structure 3 includes a scraper tongue 31 disposed between two adjacent protective covers 1. The scraper tongue 31 includes a fixed end 311 and a scraping end 312. The angle between the fixed end 311 and the scraping end 312 is an obtuse angle. The fixed end 311 of the scraper tongue 31 is fixed between two adjacent protective covers 1, and the scraping end 312 of the scraper tongue 31 is fastened to the upper surface of the front protective cover 11 and abuts against the upper surface of the front protective cover 1. When the protective cover extends or retracts, the scraper tongue 31 scrapes off the chips and coolant on the upper surface of the front protective cover 11, thereby preventing chips or coolant from entering the machine tool through the gap between two adjacent protective covers and damaging the guide rails or lead screws.

[0021] In one embodiment, such as Figure 4 As shown, an upper pressure plate 4 is provided between the scraper tongue 31 and the rear protective cover 12. The shape of the upper pressure plate 4 matches the shape of the scraper tongue 31, that is, the upper pressure plate 4 is also bent. One end of the upper pressure plate 4 is located between the fixed end 311 of the scraper tongue 31 and the rear protective cover 12, and the free end of the upper pressure plate 4 presses on the scraping end 312 of the scraper tongue 31. By pressing down the scraper tongue 31 with the free end of the upper pressure plate 4, that is, by pressing down the folded edge, the scraper tongue 31 is prevented from lifting up during the extension and retraction of the protective cover. At the same time, the scraper tongue 31 is also bent, which increases its strength and allows the scraper tongue 31 to fit tightly against the upper surface of the front protective cover 11.

[0022] In another embodiment, such as Figure 4 As shown, a brass base plate 5 is provided between the fixed end 311 of the scraper tongue 31 and the front end cover 11.

[0023] In another embodiment, the scraper tongue 31 is made of metal, and the scraping end 312 of the scraper tongue 31 uses a spring steel sheet with a thickness of 0.1mm to 0.2mm. The scraping end 312 is made of spring steel to prevent hard friction between the scraping end 312 and the front guard 11, which would prevent the guard from extending and retracting properly. In this invention, by using a metal scraper tongue, high-temperature debris can be prevented from burning it. Furthermore, the use of spring steel at the scraping end ensures its rigidity while preventing deformation and bending, increasing wear resistance and extending the lifespan of the scraper tongue 31.

[0024] In another embodiment, such as Figure 5As shown, matching holes are provided on the brass base plate 5, the upper pressure plate 4, the fixed end 311 of the scraper tongue 31, and the front guard 11. Through holes are designed on the upper pressure plate 4 and the front guard 11, and tapping holes are designed on the brass base plate 5. Through the thread torque of the bolt 6 and the brass base plate 5, the scraper tongue 31 and the front guard 11 are tightly fixed together, ensuring that the scraper tongue 31 scrapes the coolant and chips off the guard during the back-and-forth movement of the guard.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
