[0002] Guide rails are core components of machine tools, responsible for providing precise linear or rotary motion trajectories for moving parts, supporting the weight of the moving parts, and bearing loads such as cutting forces and inertial forces generated during machining. Through a rigid structure and low-friction design, they reduce the impact of vibration and thermal deformation on machining accuracy. Wear or contamination of guide rails can lead to decreased machine tool accuracy, increased vibration, and even malfunctions.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-5 The machine tool guide rail anti-chip sealing telescopic cover shown includes a guide rail 2 installed on the top of the machine tool 1, a movable block 3 matched on the guide rail 2, guide grooves 4 on both sides of the guide rail 2, and sealing telescopic covers 5 installed at both ends of the guide rail 2.

[0030] In this embodiment, the guide rail 2 is fixed to the top of the machine tool 1 to ensure levelness and straightness. Movable blocks 3 are installed on the guide rail 2, allowing them to slide along the guide rail, with both sides embedded in guide grooves 4.

[0031] Specifically, guide grooves 4 are machined on both sides of the guide rail 2, with a length slightly longer than the guide rail, and telescopic cylinders 51 are fixed at the ends. Sealing telescopic covers 5 are installed at both ends of the guide rail, with the main body 52 of the telescopic cover fixed to the end of the guide rail. An internal telescopic groove 54 is provided, and a guide block 56 is installed at the bottom. A movable cover 53 is inserted into the telescopic groove 54, with a guide strip 55 at the bottom matching the guide groove 4, and a sealing strip 58 installed at the end.

[0032] Reference Figure 4-5The sealing telescopic cover 5 includes telescopic cylinders 51 installed at both ends of the guide rail 2. A telescopic cover body 52 is installed on one side of the telescopic cylinder 51. A movable cover 53 is installed on the inner side of the telescopic cover body 52. ​​The movable cover 53 moves within the telescopic cover body 52. ​​A connecting component 6 is provided between the movable cover 53 at both ends and the two ends of the movable block 3.

[0033] Specifically, the connecting component 6 connects one end of the movable cover 53 to both ends of the movable block 3, and the two ends of the sealing telescopic cover 5 cooperate with the sealing guide rail 2.

[0034] Specifically, the telescopic cover body 52 has a telescopic groove 54 on its inner side, a movable cover 53 is installed in the telescopic groove 54, the bottom of the movable cover 53 is provided with a guide strip 55 that matches the guide groove 4, and the bottom of the telescopic cover body 52 is also provided with a guide block 56 that matches the guide groove 4.

[0035] Specifically, the guide block 56 is smaller than the guide strip 55, and the guide block 56 is located on the bottom of the telescopic cover body 52 away from the telescopic end. The internal dimensions of the telescopic groove 54 match the dimensions of the movable cover 53. The end of the movable cover 53 is provided with an installation groove 57, and a sealing strip 58 is installed in the installation groove 57. The sealing strip 58 contacts the outer walls of both ends of the movable block 3.

[0036] In this embodiment, the connecting component 6 has a mounting block 61 welded to the top front end of the movable cover 53, which is aligned with both ends of the movable block 3. The positioning post 63 is inserted through the mounting hole 62, and a shock-absorbing spring 64 is fitted on the outside. Both ends are fixed with limiting rings 65, and the limiting plate 31 restricts the displacement of the positioning post.

[0037] Reference Figure 3 The connecting component 6 includes a mounting block 61 located at the top front end of the movable cover 53. Mounting holes 62 are provided above both ends of the mounting block 61 and the movable block 3. Positioning posts 63 are provided inside the mounting holes 62. The two ends of the positioning posts 63 are located at both ends of the mounting holes 62. Shock-absorbing springs 64 are installed on the outside of the positioning posts 63. The shock-absorbing springs 64 are located inside the mounting holes 62 on the movable block 3. Limiting rings 65 are also provided at both ends of the positioning posts 63.

[0038] Specifically, a limiting plate 31 is provided on the top of the movable block 3 inside the mounting hole 62, and the end limiting ring 65 of the positioning column 63 is restricted to one side of the limiting plate 31.

[0039] Reference Figure 1-2 The overall length of the guide groove 4 is at least longer than the overall length of the guide rail 2. The telescopic cylinder 51 is fixed at both ends of the guide groove 4. The inside of the guide groove 4 is arc-shaped on both sides and moves towards the center.

[0040] In this embodiment, the contact pressure between the sealing strip 58 and the outer wall of the moving block 3 is adjusted to ensure a tight fit. The matching of the guide strip 55 with the guide groove 4 and the guide block 56 is tested to ensure smooth extension and retraction of the moving cover.

[0041] In this embodiment, the operation process is as follows:

[0042] 1. When the moving block 3 moves along the guide rail 2, it drives the moving cover 53 to extend and retract synchronously through the connecting component 6. The telescopic cylinder 51 automatically adjusts the unfolded length of the telescopic cover body 52 according to the position of the moving block.

[0043] 2. The movable cover 53 slides along the telescopic groove 54, and the bottom guide strip 55 cooperates with the guide groove 4 to prevent displacement. The sealing strip 58 is always in close contact with the outer wall of the movable block 3 to prevent debris from entering the guide rail.

[0044] 3. When the moving block stops suddenly or vibrates, the shock-absorbing spring 64 absorbs the impact force to prevent damage to the sealing structure from hard collisions. The limiting ring 65 and the limiting plate 31 together limit the displacement of the positioning post 63 to ensure connection stability.

[0045] In this embodiment, the sealing strip 58 dynamically fits against the moving block 3, effectively isolating contaminants such as cutting fluid and metal shavings, and reducing guide rail wear. The moving cover 53 works in conjunction with the telescopic cylinder 51 to automatically adapt to the stroke of the moving block, covering the entire length of the guide rail.

[0046] Specifically, the arc-shaped design of the shock-absorbing spring 64 and the guide groove 4 reduces movement impact and vibration, extending the equipment's lifespan. The modular design facilitates disassembly and replacement of the sealing strip 58 or the guide strip 55, resulting in low maintenance costs.

[0047] Specifically, the precise matching between the guide bar 55 and the guide groove 4 ensures that the moving cover 53 is free from jamming, thereby improving the machine tool's operating accuracy.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
