Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a self-lubricating guide rail for numerical control machine tools. Background Art

[0002] The main function of CNC machine tool guide rails is to support and guide moving parts. Specifically, guide rails ensure that the machine tool maintains the correct motion trajectory during operation, while providing the necessary support to ensure the stability and precision of the machine tool. To ensure the lubrication of the slider on the guide rail, lubricating oil is used to lubricate the guide rail. There are two types of lubrication: manual lubrication and self-lubrication. When self-lubricating, lubricating oil is installed in the slider to lubricate the slider as it moves, but it will cause the lubricating oil to leak all the time, resulting in a large loss of lubricating oil. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art that lubricating oil is always in a leakage state, resulting in a large loss of lubricating oil, and to propose a self-lubricating guide rail for a CNC machine tool.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A self-lubricating guide rail for a numerically controlled machine tool is designed, comprising a slide rail, a slider being slidably arranged on the slide rail, a storage cavity being provided on the slider, a liquid outlet being provided in the storage cavity, a sealing plug being abutted in the liquid outlet, an inclined surface being provided on the liquid outlet, a threaded rod being fixedly connected to the sealing plug, a threaded barrel being threadedly connected to the threaded rod, the threaded barrel being rotatably connected to the slide rail via a sealed bearing, and a liquid injection mechanism being provided on the storage cavity.

[0006] Preferably, the liquid injection mechanism includes a connecting pipe, the storage chamber is connected with a connecting pipe, and a connecting cap is threadedly connected to the connecting pipe.

[0007] Preferably, a rotating block is fixedly connected to the threaded barrel, a positioning rod is connected to the rotating block via a limiting mechanism, a fixing hole is opened on the slider, the positioning rod is inserted into the fixing hole, and the positioning rod passes through the rotating block.

[0008] Preferably, the limiting mechanism includes a fixed block fixedly connected to the positioning rod, and a spring fixedly connected between the fixed block and the rotating block.

[0009] Preferably, a pulling block is fixedly connected to the positioning rod.

[0010] The utility model proposes a self-lubricating guide rail for a CNC machine tool, which has the following beneficial effects: by rotating the threaded barrel, the position of the threaded rod in the threaded barrel is adjusted, thereby driving the sealing plug to move, the liquid outlet is opened, and the lubricating oil flows into the slide rail for lubrication; after lubrication, the sealing plug and the liquid outlet are re-sealed by rotating the threaded barrel, thereby preventing leakage of the lubricating oil and avoiding waste of the lubricating oil.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1: Reference Figure 1-5, a self-lubricating guide rail of a CNC machine tool, including a slide rail 1, a slider 2 is slidably provided on the slide rail 1, a storage chamber 4 is opened on the slider 2, a liquid outlet is opened in the storage chamber 4, a sealing plug 8 is abutted in the liquid outlet to prevent the sealing plug 8 from rotating, an inclined surface is provided on the liquid outlet, a threaded rod 10 is fixedly connected to the sealing plug 8, and a threaded cylinder 9 is threadedly connected to the threaded rod 10. The threaded cylinder 9 is rotatably connected to the slider 2 through a sealed bearing, and a liquid injection mechanism is provided on the storage chamber 4. When lubrication is needed, the threaded cylinder 9 is rotated to adjust the position of the threaded rod 10 in the threaded cylinder 9, thereby driving the sealing plug 8 to move, which will open the liquid outlet and allow the lubricating oil to flow into the slide rail 1 for lubrication. After lubrication, the threaded cylinder 9 is rotated to reseal the sealing plug 9 and the liquid outlet, thereby preventing leakage of the lubricating oil and avoiding waste of the lubricating oil.

[0019] The injection mechanism includes a connecting pipe 5 , which is connected to the storage chamber 4 , and a connecting cover 6 is threadedly connected to the connecting pipe 5 . The connecting cover 6 is opened to inject the lubricating oil.

[0020] Example 2: Since the slider 2 moves back and forth, it is easy to vibrate the threaded barrel 9, causing the threaded barrel 9 to rotate, causing the sealing plug 9 to move, resulting in the opening of the liquid outlet. Figure 1-5 As another preferred embodiment of the present invention, on the basis of embodiment 1, a rotating block 12 is fixedly connected to the threaded barrel 9, and a positioning rod 11 is connected to the rotating block 12 through a limiting mechanism. A fixing hole is opened on the slider 2, and the positioning rod 11 is inserted into the fixing hole. The positioning rod 11 passes through the rotating block 12. The positioning rod 11 and the fixing hole are used to limit the rotating block 12, thereby limiting the threaded barrel 9, preventing the threaded barrel 9 from rotating during work.

[0021] The limiting mechanism includes a fixed block 3 fixedly connected to the positioning rod 11, and a spring 13 fixedly connected between the fixed block 3 and the rotating block 12. The design of the spring 13 limits the positioning rod 11 and prevents the limiting rod 11 from escaping from the fixing hole.

[0022] The positioning rod 11 is fixedly connected to a pulling block 7 , which plays a role in being easy to grasp. When the pulling block 7 is pulled to move, the positioning rod 11 is driven to disengage from the fixing hole, thereby releasing the limit on the threaded barrel 9 .

[0023] During lubrication, pull the pulling block 7 to move the positioning rod 11 and disengage it from the fixing hole. Then rotate the rotating block 12 to drive the threaded barrel 9 to rotate, adjust the position of the threaded rod 10 in the threaded barrel 9, and thereby drive the sealing plug 8 to move, so that the liquid outlet is opened and the lubricating oil flows into the slide rail 1. When the slider 2 moves back and forth, the lubricating oil is applied to the slide rail 1. After completion, the sealing plug 8 is reset.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
