Description

Technical Field

[0001] This utility model relates to the field of engraving and milling machines, and in particular to a CNC engraving and milling machine with a slide rail shielding structure. Background Technology

[0002] A CNC engraving and milling machine is a type of CNC machine tool capable of both engraving and milling. Typically, the engraving and milling assembly moves horizontally via a horizontal rail and vertically via a vertical rail. The cutter head mounted on the assembly automatically engraves the workpiece below. During engraving or milling, a large amount of dust is generated. This dust easily adheres to or accumulates on the exposed slide rails, forming stubborn sludge with the lubricating oil. This reduces the precision of the fit between the slide rail and the slider, consequently decreasing the positioning accuracy of the engraving and milling cutter head. Furthermore, compared to the vertical rail, the horizontal rail's sliding surface is horizontal, making it more prone to sludge accumulation. Therefore, protecting the horizontal rail can significantly reduce sludge buildup, thereby decreasing the maintenance frequency of the engraving and milling machine. Utility Model Content

[0003] The purpose of this application is to provide a CNC engraving and milling machine with a slide rail shielding structure, which aims to solve the problems existing in the prior art.

[0004] This application provides a CNC engraving and milling machine with a slide rail shielding structure. The engraving and milling cutter assembly of the engraving and milling machine is slidably connected to a back plate via a slide rail and a slider. A cover is fixed on the back plate corresponding to the slide rail. A first window is provided on the cover, and the length of the first window matches the moving distance of the engraving and milling cutter assembly. A baffle is slidably disposed in the gap between the cover and the slide rail. A second window is provided on the baffle, with a width greater than the width of the slide rail and a length greater than the length of the slider. The width of the first window is greater than the width of the second window. The slider passes through the first window and the second window and is mounted on the slide rail. The slider and the second window are relatively fixed.

[0005] Furthermore, the baffle plate is arranged in a loop around the back plate, and corner wheels are installed at the four corners of the back plate. The baffle plate is reversed by the corner wheels.

[0006] Furthermore, a back wheel is installed on the back of the back plate. The back wheel is at the same height as the corner wheel, and the baffle moves in a straight line on the back of the back plate via the back wheel.

[0007] Furthermore, multiple support wheels are embedded in the cover, and the support wheels cooperate with the corner wheels and back wheels to clamp the baffle in the middle.

[0008] Furthermore, the cover is installed in a loop around the back plate, covering the outside of the baffle.

[0009] Furthermore, grooves are provided on the upper and lower sides of the corresponding baffle inside the cover.

[0010] The beneficial effects of this invention are: it can shield and protect the horizontal rail of the engraving and milling machine, isolating it from external dust and debris, thereby preventing the formation of sludge and maintaining the precision of the engraving and milling machine. This invention has a simple structure, uses readily available materials, and can be added to existing engraving and milling machines without the need to purchase new machines, thus helping to control production costs.

[0018] 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.

[0019] like Figure 1 The conventional CNC engraving and milling machine shown has an engraving and milling cutter assembly 1 that is slidably connected to a back plate 4 via a slide rail 2 and a slider 3. The horizontal movement of the engraving and milling cutter assembly 1 is achieved by the slide rail 2 on the back plate 4.

[0020] This application discloses a CNC engraving and milling machine with a slide rail 2 shielding structure, such as Figures 2-5As shown, a cover 5 is fixed to the back plate 4 corresponding to the slide rail 2, and the cover 5 covers the slide rail 2. The cover 5 has a first window 6, the length of which matches the moving distance of the engraving and milling cutter assembly 1 on the slide rail 2. A baffle 7 is slidably disposed in the gap between the cover 5 and the slide rail 2. The width of the baffle 7 is greater than the width of the first window 6. The baffle 7 is in a loop around the back plate 4. A second window 8 is formed on the baffle 7, the width of which is greater than the width of the slide rail 2 and the length of which is greater than the length of the slider 3. The width of the first window 6 is greater than the width of the second window 8. The slider 3 is installed on the slide rail 2 through the first window 6 and the second window 8, and the slider 3 and the second window 8 are relatively fixed. When the slider 3 slides along the slide rail 2, the second window 8 can be dragged to make the baffle 7 rotate as a whole. The part of the baffle 7 outside the second window 8 covers the slide rail 2. Together with the cover 5, the slide rail 2 is completely covered, isolating it from external dust and debris.

[0021] The baffle 7 is a thin strip, which can be made of steel or rubber and is flexible and bendable. Corner wheels 9 are installed at each of the four corners of the back plate 4, and the baffle 7 is redirected via the corner wheels 9. The corner wheels 9 support the baffle 7, allowing it to rotate.

[0022] A back wheel 10 is mounted on the back of the back plate 4. The back wheel 10 is at the same height as the corner wheel 9, and the baffle 7 moves linearly on the back of the back plate 4 via the back wheel 10. A cover 5, similar to the baffle 7, is installed in a loop around the back plate 4, covering the baffle 7 completely. Support wheels 11 are embedded on the front, back, left, and right sides of the cover 5. The support wheels 11 cooperate with the corner wheel 9 and the back wheel 10 to clamp the baffle 7 in the middle. Sliding grooves 12 are provided inside the cover 5 corresponding to the upper and lower sides of the baffle 7 to limit the movement of the baffle 7, thus ensuring the stability of the baffle 7 during rotation.
