Description

Technical Field

[0001] This utility model relates to the field of machine tool guideway technology, specifically a sealed and protective CNC machine tool guideway cover. Background Technology

[0002] A guide rail is a track groove or ridge made of metal or other materials. It is a device that supports, fixes, and guides moving devices or equipment while reducing friction. Used in linear reciprocating motion applications, it has a higher rated load than linear bearings and can withstand a certain amount of torque, enabling high-precision linear motion under high loads. Guide rails are mainly divided into two categories: roller guide rails and ball guide rails. CNC machine tool guide rails are key components of machine tools, playing a crucial role in supporting and guiding moving parts along a prescribed trajectory.

[0003] Chinese patent CN217122628U discloses a "guide rail base for CNC machine tools," comprising a slide rail mounted on the upper surface of a base, a slider slidably connected to the outer surface of the slide rail, first oiling holes on both the left and right sides of the slider, a second oiling hole on the lower surface of the slider, and a support plate fastened to the upper surface of the base. This guide rail base for CNC machine tools, through the first and second oiling holes, facilitates the addition of lubricating oil to the bottom of the inner wall and the bottom of the outer surface of the slider, improving the stability of the slider's movement on the outer surface of the slide rail, reducing wear on the slider's force-bearing surface, and thus extending the slider's service life. By setting the bottom of the slider to slide on the inclined surface of the support plate, the stability of the slider's movement is improved, and lubricating oil is facilitated to flow from the second oiling hole into the inclined surface of the support plate, thereby enhancing the practicality of the device.

[0004] However, in practical use, existing technologies often result in a lot of waste chips splashing onto the guide rails during machining on some CNC machine tools. After prolonged use, the accumulation of waste chips on the guide rails can affect the smoothness of their operation. Furthermore, the impact of the waste chips on the guide rails can cause wear on their outer surface, shortening their service life. Therefore, a sealed protective cover for CNC machine tool guide rails is proposed to solve the aforementioned problems. Utility Model Content

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-4As shown, a sealed protective cover for CNC machine tool guideways includes a guideway assembly 1, which comprises two guideways. A slide block 2 is slidably connected to the guideway assembly 1. The machining device of the CNC machine tool is mounted on the slide block 2. The machining device is driven to move by a drive device, causing the machining device and the slide block 2 to slide on the guideway assembly 1. An outer protective cover 3 is connected to one end of the slide block 2. An inner protective cover 4 is connected to the guideway assembly 1. The outer wall of the inner protective cover 4 is slidably connected to the inner wall of the outer protective cover 3. The outer protective cover 3 and the inner protective cover 4 can protect the guideway assembly 1, protecting it within the outer and inner protective covers. Inside the inner cover 4, when the slide 2 slides, it drives the outer cover 3 to move. The outer cover 3 then slides on the inner cover 4, achieving the effect that the outer cover 3 and inner cover 4 can extend and retract according to the movement of the slide 2. This ensures that the outer cover 3 and inner cover 4 always maintain protection for the guide rail assembly 1 when the slide 2 moves. It also includes a cleaning component 5 for cleaning the connection between the inner cover 4 and the outer cover 3. The cleaning component 5 includes a rotating shaft 51, which is rotatably mounted on the outer cover 3 via two brackets. A first gear 56 is rotatably mounted on each of the two brackets holding the rotating shaft 51. Friction wheels 53 are rotatably mounted on both sides of the protective cover 3 via brackets. A cleaning roller 52 is connected to the outer wall of the rotating shaft 51. A first bevel gear 54 is connected to the top of each friction wheel 53. A second bevel gear 55 is connected to a first gear 56. Second gears 57 are connected to both ends of the rotating shaft 51. The two first bevel gears 54 mesh with the two second bevel gears 55, and the two first gears 56 mesh with the two second gears 57. The two friction wheels 53 contact the outer walls of both sides of the inner protective cover 4. There is significant friction between the friction wheels 53 and the outer walls of the inner protective cover 4, causing… When the two friction wheels 53 move, they are driven by the inner cover 4 to rotate. The cleaning roller 52 is located above the connection position between the inner cover 4 and the outer cover 3. The cleaning roller 52 contacts the top surface of the inner cover 4. When the cleaning roller 52 rotates, it cleans the connection part between the inner cover 4 and the outer cover 3. This prevents the inner cover 4 from being stuck in the connection part between the inner cover 4 and the outer cover 3 when it retracts into the inner cover 3. This would cause the waste to be stuck inside the connection part between the inner cover 4 and the outer cover 3, thus affecting the smoothness of its sliding connection.

[0026] In this embodiment, the outer cover 3 and the inner cover 4 are designed to seal and protect the guide rail assembly 1 by working together, thus preventing debris from affecting the guide rail assembly 1. The cleaning component 5 is designed so that when the outer cover 3 and the inner cover 4 extend or retract, the cleaning roller 52 rotates to clean the connection between the inner cover 4 and the outer cover 3, thus preventing debris from getting stuck in the connection between the inner cover 4 and the outer cover 3 and affecting its use.

[0027] Example 2

[0028] Please see Figures 1-6As shown, the collection component 6 is used to collect waste debris. The collection component 6 includes a collection box 61, which is mounted on top of the outer cover 3. A slide rod 62 is slidably mounted through the inner wall of the collection box 61. A scraper 63 is connected to the outer wall of the slide rod 62. One end of the slide rod 62 is connected to a spring seat 66, and a spring is provided between the spring seat 66 and the outer wall of the collection box 61. The other end of the slide rod 62 is connected to a lever 64. One end of the cleaning roller 52 is connected to a curved ring 65. One side of the scraper 63 contacts the cleaning roller 52, and the other side of the scraper 63 is located inside the collection box 61. A groove is provided on the lever 64, and the groove of the lever 64 connects with the curved ring 65. The outer wall of the sliding contact is maintained, and the groove on the lever 64 always abuts against the curved ring 65. When the curved ring 65 rotates, the lever 64 moves back and forth following the curved surface of the ring 65, causing the lever 64 to drive the slide rod 62 to move back and forth. The slide rod 62 drives the scraper 63 to move back and forth, causing the scraper 63 to scrape the waste attached to the surface of the cleaning roller 52 into the collection box 61 during its back and forth movement. The scraper 63 promotes the cleaning effect through its reciprocating movement. The staff cleans the collection box 61 regularly, reducing the disassembly and cleaning steps of the cleaning roller 52; the inner wall of the collection box 61 Two ball bearing sliders 610 are slidably mounted, and scrapers 611 are connected to the ball bearing sliders 610. A bidirectional screw 67 is rotatably connected through the inner wall of the collection box 61. A first pulley 68 is connected to the outer surface of the end of the rotating shaft 51 away from the curved ring 65. A second pulley 69 is connected to the end of the bidirectional screw 67 near the first pulley 68. Side boxes 612 are connected to both sides of the outer cover 3. The first pulley 68 and the second pulley 69 are connected by a belt. The bidirectional screw 67 has two threaded grooves in opposite directions. The two threaded grooves of the bidirectional screw 67 are threadedly connected to the two ball bearing sliders 610 respectively. The connection between the 10 and the bidirectional screw 67 is equipped with ball bearings. When the bidirectional screw 67 rotates, it drives the two ball bearing sliders 610 to move horizontally in opposite directions through the two threaded grooves. Both scrapers 611 are in contact with the top surface of the outer cover 3. When the slide 2 is at the leftmost position, the two scrapers 611 are together. When the slide 2 starts to move, the two scrapers 611 move away from each other. During this process, the waste on the outer cover 3 is pushed to both sides. When the slide 2 moves to the rightmost position, the two scrapers 611 move to the top of the two side boxes 612 respectively. The two scrapers 611 push the waste into the two side boxes 612 for collection.

[0029] In this embodiment, the collection component 6 enables the scraper 63 to scrape the debris attached to the cleaning roller 52 into the collection box 61 for collection by reciprocating movement, thus maintaining the cleanliness of the cleaning roller 52 and ensuring the cleaning effect. The two scraper strips 611 are designed to follow the movement of the slide block 2 to scrape the debris on the outer cover 3 into the two side boxes 612 for collection, maintaining the cleanliness of the surface of the outer cover 3 and reducing the amount of work required for cleaning the outer cover 3.

[0030] This utility model discloses a sealed protective cover for CNC machine tool guideways. In use, the machining device of the CNC machine tool is mounted on a slide 2. A drive device moves the machining device, causing it and the slide 2 to slide on the guideway assembly 1. The outer cover 3 and inner cover 4 protect the guideway assembly 1, enclosing it within the outer cover 3 and inner cover 4. When the slide 2 slides, it moves the outer cover 3, which in turn slides on the inner cover 4, thus ensuring that the outer cover 3 and inner cover 4 can effectively protect the guideway assembly 1. The extension and retraction effect based on the movement of the slide 2 ensures that the outer cover 3 and inner cover 4 always protect the guide rail assembly 1 when the slide 2 moves. When the outer cover 3 moves, it drives two friction wheels 53 to move via the bracket. The friction wheels 53 have significant friction with the outer wall of the inner cover 4, causing them to rotate under the influence of the inner cover 4. The rotation of the friction wheels 53 drives the second bevel gear 55 to rotate via the first bevel gear 54. The second bevel gear 55, through the first bevel gear 54... Wheel 56 drives gear 57 to rotate. When both gears 57 rotate, they drive shaft 51 to rotate. Shaft 51 drives cleaning roller 52 to rotate. When cleaning roller 52 rotates, it cleans the connection between inner cover 4 and outer cover 3. This prevents debris from getting stuck in the connection between inner cover 4 and outer cover 3 when inner cover 4 retracts into outer cover 3, thus affecting the sliding connection. While ensuring smooth operation, there is also the possibility of the inner cover 4 and the outer cover 3 getting stuck. The outer cover 3 and the inner cover 4 are designed to seal and protect the guide rail assembly 1 by working together, preventing debris from affecting the guide rail assembly 1. The cleaning component 5 is designed so that when the outer cover 3 and the inner cover 4 extend and retract, the cleaning roller 52 rotates to clean the connection between the inner cover 4 and the outer cover 3, preventing debris from getting stuck in the connection between the inner cover 4 and the outer cover 3 and affecting its use.

[0031] When the cleaning roller 52 rotates, it drives the curved ring 65 to rotate. Because the spring seat 66 applies a pulling force to the slide rod 62 through the spring, the slide rod 62 always maintains a backward force. The lever 64 on the slide rod 62 also maintains a backward force, causing the groove on the lever 64 to always press against the curved ring 65. When the curved ring 65 rotates, the lever 64 moves back and forth following the curved surface of the curved ring 65, causing the lever 64 to drive the slide rod 62 to move back and forth. The slide rod 62 then drives the scraper 63 to move back and forth. Because the scraper 63 and the cleaning roller 52 rotate, the sliding rod 62 moves back and forth. When the cleaning roller 52 contacts the scraper 63, the scraper 63 scrapes the waste adhering to the surface of the cleaning roller 52 into the collection box 61 during its reciprocating movement. The reciprocating movement of the scraper 63 promotes the cleaning effect. The collection box 61 is cleaned regularly by the staff, reducing the disassembly and cleaning operation steps of the cleaning roller 52. When the rotating shaft 51 rotates, it drives the bidirectional screw 67 to rotate through the first pulley 68, the belt and the second pulley 69. When the bidirectional screw 67 rotates, it drives the two ball sliders 610 through the two threaded grooves. The two scrapers 611 move synchronously with the ball bearing slider 610, moving horizontally in opposite directions. When the slide 2 is at its leftmost position, the two scrapers 611 come together. As the slide 2 begins to move, the two scrapers 611 move away from each other, pushing the waste on the outer cover 3 to both sides. When the slide 2 moves to its rightmost position, the two scrapers 611 move above the two side boxes 612 respectively, pushing the waste into the two side boxes 612 for collection. When the slide 2 begins to move to the left, the two scrapers 611 move to the rightmost position. 11. Move towards each other to reset; the collection component 6 is configured so that the scraper 63 can scrape the waste attached to the cleaning roller 52 into the collection box 61 for collection by reciprocating movement, keeping the cleaning roller 52 clean and thus ensuring the cleaning effect; the two scraper strips 611 are configured so that the two scraper strips 611 can follow the movement of the slide 2 to scrape the waste on the outer cover 3 into the two side boxes 612 for collection, keeping the surface of the outer cover 3 clean and reducing the number of operations for workers to clean the outer cover 3.

[0032] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
