Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a guide rail protection device for a high-precision CNC machine tool. Background Technology

[0002] A CNC machine tool is a device whose movement and machining operations are controlled by a computer program. It can automatically complete the cutting of a workpiece according to a pre-programmed machining program. Compared with traditional machine tools, CNC machine tools have higher precision, efficiency, and flexibility. The tool post of a CNC machine tool typically uses high-precision guideways for movement, allowing for fine adjustments to the tool position, thereby improving machining accuracy.

[0003] Most existing CNC machine tool guideways have cross-sections in the shape of I-beams or other shapes with side slots. When a CNC machine tool is cutting a workpiece, some of the chips will fall onto the guideway and remain in the side slots. When the chips accumulate to an excessive amount, they will block the guideway, causing the tool holder to move poorly and thus affecting the processing efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a guide rail protection device for high-precision CNC machine tools, which can effectively solve the problem that most existing CNC machine tool guide rails have I-shaped or other side grooves. When the CNC machine tool is cutting the workpiece, some of the generated debris will fall onto the guide rail and remain in the side groove. When the amount of debris accumulates too much, it will block the guide rail, causing the tool holder to move poorly and thus affecting the processing efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0009] The slider is located inside the slider and is movably connected to the groove.

[0010] The cleaning component is disposed inside the slider and is adjacent to the slider bar;

[0011] The lubrication component is located inside the slider, and the cleaning component is connected to the inner end of the oil injection pipe.

[0012] Preferably, the cleaning component includes a strip, a pull block, a sponge strip, and a retaining ball;

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] This application designs a guide rail 1 protection device for a high-precision CNC machine tool, as shown in the attached figure. Figure 1-4 As shown, it includes a guide rail 1, a groove 2, a tool holder 3, an oil injection pipe 4, a slider 5, a slide bar 6, a cleaning component, and a lubrication component;

[0034] The groove 2 is formed on the side of the guide rail 1;

[0035] The tool holder 3 is fixedly connected to the top of the slider 5. The oil injection pipe 4 passes through the tool holder 3 and the slider 5. The outer end of the oil injection pipe 4 is located on the outer wall of the tool holder 3. The oil injection pipe 4 is used to inject lubricating oil into the oil tank 12.

[0036] The slider 6 is located inside the slider 5. The slider 6 is movably connected to the groove 2. The slider 6 is made of rigid material, which can reduce the friction between it and the groove 2 and prevent the slider 5 from disengaging from the guide rail 1. The guide rail 1 and the slider 5 together constitute the screw-type slide table of the prior art and are driven by a motor.

[0037] The cleaning component is located inside the slider 5 and is adjacent to the slider 6;

[0038] The lubrication component is located inside the slider 5, and the cleaning component is connected to the inner end of the oil injection pipe 4.

[0039] Furthermore, the cleaning components include insert 7, pull block 8, sponge strip 9, and retaining ball 10;

[0040] The insert 7 is movably connected to the inner side of the slider 5. The sponge strip 9 is pasted on the side of the insert 7. The sponge strip 9 is a replaceable design. The sponge strip 9 is coaxial with the slider 6 and has the same shape and size. The sponge strip 9 is located in the groove 2 and is used to clean and absorb the processing debris in the groove 2. At the same time, it can evenly apply lubricating oil to the inner wall of the groove 2.

[0041] Pull block 8 is fixedly connected to the outside of insert 7;

[0042] The fixing ball 10 is movably connected to the side of the insert 7 away from the sponge strip 9 by a spring. The inner side of the slider 5 has a blind hole that engages with the fixing ball 10. The fixing ball 10 is used to fix the insert 7 and prevent the insert 7 from detaching from the slider 5.

[0043] Furthermore, the lubrication assembly includes a push rod 11, an oil groove 12, a slanted slider 135, a hose 14, a push plate 15, and a limit block 16;

[0044] Oil groove 12 is installed inside slider 5 and is connected to oil injection pipe 4;

[0045] The hose 14 is fixedly connected to the bottom of the oil tank 12, and the bottom end of the hose 14 extends through to the outside of the slide bar 6;

[0046] The limiting block 16 is fixedly connected to the inner wall of the slider 5, and the limiting block 16 is in contact with the hose 14;

[0047] The push rod 11 is movably connected to the bottom of the slider 5 by a spring, and the push rod 11 is located above the slider 6;

[0048] The side of the push rod 11 is movably connected to the inclined slider 135. The top of the guide rail 1 is provided with multiple recesses that engage with the push rod 11 at equal intervals. When the push rod 11 is inside the recess, the spring is in a stretched state. At this time, the push plate 15 is separated from the limit block 16, and the hose 14 is in a smooth state. The side of the inclined slider 135 is fixedly connected to the push plate 15. The inclined slider 135 can convert the vertical movement of the push plate 15 into the horizontal movement. The width of the push plate 15 is greater than the diameter of the hose 14. The push plate 15 and the limit block 16 are located on the same plane. The limit block 16 can prevent the push plate 15 from moving too much and cutting off the hose 14. The push plate 15 and the hose 14 are adjacent.

[0049] Working principle: First, lubricating oil is injected into the oil tank 12 through the oil injection pipe 4. When the slider 5 and the tool holder 3 move, the push rod 11 moves to the recess at the top of the guide rail 1. The spring pops the push rod 11 out, and the inclined slider 13 drives the push plate 15 to separate from the limit block 16, so that the hose 14 is unobstructed. The lubricating oil flows into the groove 2 through the hose 14. Then, when the sponge strip 9 moves to the lubricating oil, the sponge strip 9 evenly spreads the lubricating oil in the groove 2 and absorbs the machining debris in the groove 2. After the push rod 11 is separated from the recess, the guide rail 1 pushes the push rod... 11 is pushed upwards, and the push plate 15 is pushed by the inclined slider 13 to close the limit block 16, thereby preventing the lubricating oil from flowing out. As the slider 5 moves along the guide rail 1, the lubricating oil flows into the groove 2 at equal distances and in equal amounts, so that the lubricating oil inside the groove 2 is evenly distributed, thereby improving the lubrication effect. After the sponge strip 9 has been used for a period of time, the insert 7 is pulled out by the pull block 8, and then a new sponge strip 9 is installed and reconnected to the slider 5. The insert 7 is fixed to the slider 5 by the fixing ball 10, thereby improving the cleaning effect of debris inside the groove 2 by regularly replacing the new sponge strip 9.

[0050] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
