Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of machine tool accessories, and specifically relates to a self-lubricating structure for a machine tool. Background Art
[0002] As a common transmission mechanism of a machine tool, a ball screw converts rotational motion into linear motion to drive a machining mechanism and a bearing mechanism to move, thereby realizing diversified machining of workpieces.
[0003] Currently, when a ball screw performs a transmission operation, it needs to be used in conjunction with a slider and rail structure. When the ball screw rotates, it drives the slider to slide inside the rail, thereby realizing smooth transmission. However, when the slider slides inside the rail, it will provide a large lateral pressure to the ball screw, thereby affecting the transmission accuracy of the ball screw. Therefore, it is necessary to regularly apply lubricating oil to the slider and the rail to reduce the sliding resistance of the slider. However, in the prior art, the application of lubricating oil to the slider and the rail mostly relies on manual operation. On the one hand, manual application of lubricating oil is time-consuming and laborious, requiring a large amount of manual labor. On the other hand, when manually applying lubricating oil, the lubricating oil can only be applied to the side walls of the slider and the rail, and it depends on the subsequent sliding of the slider to make the lubricating oil enter between the slider and the rail, thereby playing a lubricating role for the slider. However, due to the relatively tight fit between the slider and the rail, the sliding of the slider along the rail easily pushes the lubricating oil to move along the side wall of the rail, making it difficult for the lubricating oil to smoothly enter between the slider and the rail, resulting in an unsatisfactory lubricating effect for the slider. Summary of the Invention
[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the embodiments of the present invention is to provide a self-lubricating structure for a machine tool.

The first spring is sleeved outside the first telescopic hose and is used to provide support for the first telescopic hose.
[0023] As a further improvement of the present invention: the air supply assembly includes an air delivery pipe, an air supply hard pipe, and a second telescopic hose.
[0024] There are two groups of the air delivery pipes. The two groups of air delivery pipes are respectively fixedly arranged at the edges of the left and right side walls of the slider.

[0028] Compared with the prior art, the beneficial effects of the present invention are:
[0029] In the embodiments of the present invention, when the machine tool is working and the slider slides inside the slide rail body, the oil supply component supplies lubricating oil to the diversion component and makes the lubricating oil flow inside the diversion component. The flowing lubricating oil acts on the contact position between the slider and the slide rail body. On the one hand, it lubricates the slider and the slide rail body to reduce the sliding resistance of the slider. On the other hand, during the flow of the lubricating oil, the heat generated by friction between the slider and the slide rail body can be taken away, thereby realizing the heat dissipation of the slider and the slide rail body to prevent the temperature of the slider and the slide rail body from being too high and ensuring the service life of the slider and the slide rail body. When the slider slides inside the slide rail body, the air supply component can supply air to the inner wall of the slide rail body, and then blow off the debris and sundries adhered to the inner wall of the slide rail body to realize the cleaning of the debris and sundries, avoiding the debris and sundries from entering between the slider and the slide rail body as the slider slides and preventing the slider from being stuck. Compared with the prior art, when the slider slides along the slide rail body, lubricating oil can be automatically supplied to the position between the slider and the slide rail body, thereby realizing the automatic lubrication of the slider. Moreover, the supply of the lubricating oil can also perform heat dissipation treatment on the slider and the slide rail body, thereby preventing the frictional heat between the slider and the slide rail body from being too high and affecting the service life of the slider and the slide rail body.

[0042] Please refer to Figure 1 and Figure 2, this embodiment provides a self-lubricating structure for a machine tool, including a slide rail body 10, a slider 20, a diversion component 30, an oil supply component 40, and an air supply component 50. The slider 20 is slidably disposed inside the slide rail body 10. The diversion component 30 is disposed on the side wall of the slider 20. The oil supply component 40 is disposed inside the slide rail body 10. When the slider 20 slides inside the slide rail body 10, the oil supply component 40 is used to supply lubricating oil to the diversion component 30 and make the lubricating oil flow inside the diversion component 30, so as to lubricate and dissipate heat at the contact position between the slider 20 and the slide rail body 10. The air supply component 50 is disposed inside the slide rail body 10. When the slider 20 slides inside the slide rail body 10, the air supply component 50 is used to supply air to the inner wall of the slide rail body 10, so as to clean the debris and sundries adhering to the inner wall of the slide rail body 10.
[0043] When the machine tool works and the slider 20 slides inside the slide rail body 10, the oil supply component 40 supplies lubricating oil to the diversion component 30 and makes the lubricating oil flow inside the diversion component 30. The flowing lubricating oil acts on the contact position between the slider 20 and the slide rail body 10. On the one hand, it lubricates the slider 20 and the slide rail body 10 to reduce the sliding resistance of the slider 20. On the other hand, the heat generated by friction between the slider 20 and the slide rail body 10 can be carried away during the flow of the lubricating oil, so as to realize the heat dissipation of the slider 20 and the slide rail body 10, prevent the temperature of the slider 20 and the slide rail body 10 from being too high, and ensure the service life of the slider 20 and the slide rail body 10. At the same time when the slider 20 slides inside the slide rail body 10, the air supply component 50 can supply air to the inner wall of the slide rail body 10, and then blow off the debris and sundries adhering to the inner wall of the slide rail body 10, realize the cleaning of the debris and sundries, avoid the debris and sundries from entering between the slider 20 and the slide rail body 10 as the slider 20 slides, and prevent the slider 20 from being stuck.
[0044] Please refer to Figure 3 and Figure 6 , in one embodiment, the diversion component 30 includes two groups of diversion holes 301 and several first diversion grooves 302. The two groups of diversion holes 301 are respectively opened at the left and right ends of the slider 20. The several first diversion grooves 302 are respectively opened on the front and rear side walls of the slider 20. Both ends of the several first diversion grooves 302 are respectively communicated with the two groups of diversion holes 301 through a group of first diversion channels 3021. There are two groups of the oil supply component 40, and the two groups of the oil supply component 40 are respectively disposed on the left and right sides of the slider 20. One ends of the two groups of the oil supply component 40 are respectively communicated with the two groups of diversion holes 301.
[0045] When the slider 20 slides leftward inside the slide rail body 10, the lubricating oil supply component 40 on the left supplies the lubricating oil into the diversion hole 301 on the left side wall of the slider 20. After the lubricating oil enters the diversion hole 301, it enters a number of first diversion grooves 302 on the front and rear side walls of the slider 20 through corresponding first diversion channels 3021 and flows rightward along the inside of the first diversion grooves 302. When the lubricating oil flows to the right end position of the first diversion grooves 302, it converges into the diversion hole 301 on the right side wall of the slider 20 through corresponding first diversion channels 3021 and then enters the lubricating oil supply component 40 on the right through this diversion hole 301; conversely, when the slider 20 slides rightward inside the slide rail body 10, the lubricating oil supply component 40 on the right supplies the lubricating oil into the diversion hole 301 on the right side wall of the slider 20. After the lubricating oil enters the diversion hole 301, it enters a number of first diversion grooves 302 on the front and rear side walls of the slider 20 through corresponding first diversion channels 3021 and flows leftward along the inside of the first diversion grooves 302. When the lubricating oil flows to the left end position of the first diversion grooves 302, it converges into the diversion hole 301 on the left side wall of the slider 20 through corresponding first diversion channels 3021 and then enters the lubricating oil supply component 40 on the left through this diversion hole 301; when the lubricating oil flows along the inside of the first diversion grooves 302, it can act on the front and rear contact positions between the slide rail body 10 and the slider 20, so as to lubricate the front and rear side walls of the slider 20, reduce the sliding resistance of the slider 20, and at the same time, the flowing lubricating oil can take away the heat between the slider 20 and the slide rail body 10, realizing the heat dissipation of the slider 20 and the slide rail body 10.
[0046] Please refer to Figure 4 and Figure 7 In one embodiment, the diversion component 30 further includes a number of second diversion grooves 303. The second diversion grooves 303 are opened on the bottom wall of the slider 20, and both ends of the second diversion grooves 303 are respectively communicated with the two groups of diversion holes 301 through a group of second diversion channels 3031.
[0047] When the slider 20 slides leftward inside the slide rail body 10 so that the oil supply assembly 40 on the left supplies lubricating oil into the diversion holes 301 on the left side wall of the slider 20, a part of the lubricating oil flows through a number of first diversion grooves 302 on the front and rear side walls of the slider 20 according to the aforementioned process, and another part of the lubricating oil enters a number of second diversion grooves 303 on the bottom wall of the slider 20 through the corresponding number of second diversion channels 3031 and flows rightward along the number of second diversion grooves 303. When the lubricating oil flows to the right end position of the number of second diversion grooves 303, it converges into the diversion holes 301 on the right side wall of the slider 20 through the corresponding number of second diversion channels 3031, and then enters the oil supply assembly 40 on the right through the diversion holes 301; similarly, when the slider 20 slides rightward inside the slide rail body 10 so that the oil supply assembly 40 on the right supplies lubricating oil into the diversion holes 301 on the left side wall of the slider 20, a part of the lubricating oil flows through a number of first diversion grooves 302 on the front and rear side walls of the slider 20 according to the same aforementioned process, and another part of the lubricating oil enters a number of second diversion grooves 303 on the bottom wall of the slider 20 through the corresponding number of second diversion channels 3031 and flows leftward along the number of second diversion grooves 303. When the lubricating oil flows to the left end position of the number of second diversion grooves 303, it converges into the diversion holes 301 on the left side wall of the slider 20 through the corresponding number of second diversion channels 3031, and then enters the oil supply assembly 40 on the left through the diversion holes 301; therefore, when the slider 20 slides left and right inside the slide rail body 10, the oil supply assembly 40 can drive the lubricating oil to flow through the front side, rear side and bottom of the slider 20, thereby increasing the lubrication and heat dissipation area of the slider 20 and improving the lubrication and heat dissipation effects of the slider 20 and the slide rail body 10.
[0048] Please refer to Figure 3 and Figure 4 , in one embodiment, the number of the first diversion grooves 302 on the front and rear side walls of the slider 20 can be horizontally distributed or inclinedly distributed, which is not limited herein. The number of the second diversion grooves 303 on the bottom wall of the slider 20 can also be horizontally distributed or inclinedly distributed, which is not limited herein. The number of the first diversion grooves 302 and the number of the second diversion grooves 303 can be in an S-shaped curved structure or in other shaped structures, which is also not limited herein.
[0049] Please refer to Figure 1 and Figure 5, in one embodiment, end plates 101 are fixedly arranged at both ends of the slide rail body 10. The two oil supply assemblies 40 have the same structure and both include an oil supply hard pipe 401 and a first telescopic hose 404. The two oil supply hard pipes 401 are respectively fixedly arranged on the left and right side walls of the slider 20 and are respectively communicated with the two diversion holes 301. One end of each of the two oil supply hard pipes 401 away from the slider 20 is respectively communicated with a first telescopic hose 404. One end of each of the two first telescopic hoses 404 away from the corresponding oil supply hard pipe 401 is respectively connected to an end plate 101. Lubricating oil liquid is stored inside both of the two first telescopic hoses 404.
[0050] When the slider 20 slides leftward along the inside of the slide rail body 10, the first telescopic hose 404 on the left side of the slider 20 is compressed and shortened, and the first telescopic hose 404 on the right side of the slider 20 is stretched and lengthened. When the left first telescopic hose 404 is compressed, the lubricating oil liquid inside it enters the left diversion hole 301 from the left oil supply hard pipe 401, and then enters a number of first diversion channels 3021 and a number of second diversion channels 3031 and then enters a number of first diversion grooves 302 and a number of second diversion grooves 303. After the lubricating oil liquid enters the number of first diversion grooves 302 and the number of second diversion grooves 303, it flows rightward and converges into the diversion hole 301 on the right side wall of the slider 20 from a number of first diversion channels 3021 and a number of second diversion channels 303 at the right position, and then enters the inside of the right elongated first telescopic hose 404 from the right diversion hole 301; when the slider 20 slides rightward along the inside of the slide rail body 10, the first telescopic hose 404 on the right side of the slider 20 is compressed and shortened, and the first telescopic hose 404 on the left side of the slider 20 is stretched and lengthened. When the right first telescopic hose 404 is compressed, the lubricating oil liquid inside it enters the right diversion hole 301 from the right oil supply hard pipe 401, and then enters a number of first diversion channels 3021 and a number of second diversion channels 3031 and then enters a number of first diversion grooves 302 and a number of second diversion grooves 303. After the lubricating oil liquid enters the number of first diversion grooves 302 and the number of second diversion grooves 303, it flows leftward and converges into the diversion hole 301 on the left side wall of the slider 20 from a number of first diversion channels 3021 and a number of second diversion channels 303 at the left position, and then enters the inside of the left elongated first telescopic hose 404 from the left diversion hole 301.
[0051] Please refer to Figure 5 , in one embodiment, an annular protrusion 402 is fixedly arranged outside the oil supply hard pipe 401. The annular protrusion 402 is connected to the end plate 101 through a first spring 405. The first spring 405 is sleeved outside the first telescopic hose 404 and is used to provide support for the first telescopic hose 404.
[0052] When the slider 20 slides left and right inside the slide rail body 10, the first telescopic hoses 404 on the left and right sides of the slider 20 are adaptively compressed and stretched. During the compression and stretching of the first telescopic hoses 404, the first springs 405 are synchronously compressed and stretched. By providing support and protection to the first telescopic hoses 404 outside the first telescopic hoses 404 through the first springs 405, the telescoping of the first telescopic hoses 404 is kept relatively linear, thereby preventing the first telescopic hoses 404 from bending and deforming when compressed, so that the lubricating oil liquid inside the first telescopic hoses 404 can be smoothly pressed into the corresponding diversion holes 301, thereby ensuring that the lubricating oil liquid can smoothly flow along the inside of the first diversion groove 302 and the second diversion groove 303.
[0053] Please refer to Figure 5 , in one embodiment, the air supply assembly 50 includes an air delivery pipe 501, an air supply rigid pipe 503, and a second telescopic hose 504. There are two groups of the air delivery pipes 501, and the two groups of the air delivery pipes 501 are respectively fixedly arranged at the edges of the left and right side walls of the slider 20. A plurality of air delivery holes 502 are opened on the side walls of the two groups of the air delivery pipes 501. A group of the air supply rigid pipes 503 are respectively fixedly arranged on the side walls of the two groups of the air delivery pipes 501. One group of the second telescopic hoses 504 are respectively arranged at the ends of the two groups of the air supply rigid pipes 503 away from the corresponding air delivery pipes 501. One group of the end plates 101 are respectively connected to the ends of the two groups of the second telescopic hoses 504 away from the corresponding air supply rigid pipes 503.
[0054] When the slider 20 slides left inside the slide rail body 10, the second telescopic hose 504 on the left side of the slider 20 is compressed and shortened, and the telescopic hose 504 on the right side of the slider 20 is stretched and lengthened. When the second telescopic hose 504 on the left side is compressed, the air inside it is pressed into the corresponding air supply rigid pipe 503, then enters the air delivery pipe 501 on the left side through the air supply rigid pipe 503, and finally is output through a plurality of air delivery holes 502 on the side wall of the air delivery pipe 501 on the left side, so as to act on the inner wall of the slide rail body 10 to blow off the debris and sundries attached to the inner wall of the slide rail body 10, avoiding the debris and sundries from entering between the slider 20 and the slide rail body 10 as the slider 20 slides left; similarly, when the slider 20 slides right inside the slide rail body 10, the second telescopic hose 504 on the right side of the slider 20 is compressed and shortened, and the telescopic hose 504 on the left side of the slider 20 is stretched and lengthened. When the second telescopic hose 504 on the right side is compressed, the air inside it is pressed into the corresponding air supply rigid pipe 503, then enters the air delivery pipe 501 on the right side through the air supply rigid pipe 503, and finally is output through a plurality of air delivery holes 502 on the side wall of the air delivery pipe 501 on the right side, so as to act on the inner wall of the slide rail body 10 to blow off the debris and sundries attached to the inner wall of the slide rail body 10, avoiding the debris and sundries from entering between the slider 20 and the slide rail body 10 as the slider 20 slides right.
[0055] Please refer to Figure 5 In one embodiment, an extension block 403 is fixedly arranged on the side wall of the annular protrusion 402. The air supply rigid pipe 503 passes through the extension block 403 and is fixedly connected to the extension block 403. A second spring 505 is sleeved outside the second telescopic hose 504. One end of the second spring 505 is connected to the extension block 403, and the other end is connected to the end plate 101, which is used to provide support for the second telescopic hose 504, so that the telescopic movement of the second telescopic hose 504 remains relatively linear, thereby preventing the second telescopic hose 504 from being bent and deformed when compressed, so as to ensure that the air inside the second telescopic hose 504 can be smoothly pressed into the air delivery pipe 501 when compressed, so as to smoothly blow off and clean the debris on the inner wall of the slide rail body 10.
[0056] In one embodiment, the first telescopic hose 404 and the second telescopic hose 504 can be rubber bellows or metal bellows, and there is no limitation here.
[0057] The working principle of the present invention is as follows:
[0058] When the slider 20 slides leftward along the inside of the slide rail body 10, the first telescopic hose 404 at the left side position of the slider 20 is pressed, and the lubricating oil liquid inside it is pressed into the diversion holes 301 on the left side wall of the slider 20 through the oil supply rigid pipe 401 on the left side. At this time, a part of the lubricating oil liquid enters into a plurality of first diversion grooves 302 on the front and rear side walls of the slider 20 from the inside of the left diversion holes 301 and flows rightward along the plurality of first diversion grooves 302, and another part of the lubricating oil liquid enters into a plurality of second diversion grooves 303 at the bottom of the slider 20 from the inside of the left diversion holes 301 and flows rightward along the second diversion grooves 303. After the lubricating oil liquid flows to the right ends of the first diversion grooves 302 and the second diversion grooves 303, it converges into the diversion holes 301 on the right side wall of the slider 20, and then enters the first telescopic hose 404 on the right side from the right diversion holes 301; conversely, when the slider 20 slides rightward along the inside of the slide rail body 10, the first telescopic hose 404 on the right side is pressed, and the lubricating oil liquid inside it can flow leftward along a plurality of first diversion grooves 302 and a plurality of second diversion grooves 303 and finally converge into the first telescopic hose 404 on the left side. During the flow of the lubricating oil liquid along the first diversion grooves 302 and the second diversion grooves 303, on the one hand, the contact part between the slider 20 and the slide rail body 10 can be fully lubricated, and on the other hand, the frictional heat between the slider 20 and the slide rail body 10 can be taken away to realize the heat dissipation of the slider 20 and the slide rail body 10.
[0059] In the embodiment of the present invention, when the machine tool works and the slider 20 slides inside the slide rail body 10, the oil supply assembly 40 supplies lubricating oil to the diversion assembly 30 and makes the lubricating oil flow inside the diversion assembly 30. The flowing lubricating oil acts on the contact position between the slider 20 and the slide rail body 10. On the one hand, it lubricates the slider 20 and the slide rail body 10 to reduce the sliding resistance of the slider 20. On the other hand, during the flow of the lubricating oil, the heat generated by the friction between the slider 20 and the slide rail body 10 can be taken away, thereby realizing the heat dissipation of the slider 20 and the slide rail body 10, preventing the temperature of the slider 20 and the slide rail body 10 from being too high, and ensuring the service life of the slider 20 and the slide rail body 10. While the slider 20 slides inside the slide rail body 10, the air supply assembly 50 can supply air to the inner wall of the slide rail body 10, and then blow off the debris and sundries adhering to the inner wall of the slide rail body 10, realizing the cleaning of the debris and sundries, avoiding the debris and sundries from entering between the slider 20 and the slide rail body 10 as the slider 20 slides, and preventing the jamming of the slider 20. Compared with the prior art, when the slider 20 slides along the slide rail body 10, lubricating oil can be automatically supplied to the position between the slider 20 and the slide rail body 10, thereby realizing the automatic lubrication of the slider 20, and the supply of the lubricating oil can also perform heat dissipation treatment on the slider 20 and the slide rail body 10, thereby preventing the frictional heat between the slider 20 and the slide rail body 10 from being too high and affecting the service life of the slider 20 and the slide rail body 10.
