[0003] In the existing technology, when the linear guide rail and the moving block slide and rub against each other for a long time, it is necessary to add lubricating oil to the upper end regularly. Each time lubricating oil is added, it needs to be disassembled and added. This operation is very troublesome, increases the burden on the staff, and reduces the practicality of the device. Utility Model Content

[0004] The purpose of this invention is to provide a linear guide for CNC machine tools with a self-lubricating structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool linear guide with a self-lubricating structure, comprising a linear guide body, wherein sliding grooves are provided on both sides of the outer wall of the linear guide body, and through grooves are provided at the middle position of one side of the inner wall of each of the two sliding grooves, and protective nets are engaged with the inner walls of the two through grooves, and an installation groove is provided at the middle position of the inner wall of the linear guide body, and one end of the inner wall of each of the two through grooves is respectively connected to the interior of the installation groove, a pad is engaged with the upper end of the inner wall of the installation groove, and a sponge rod is engaged with the bottom of the inner wall of the installation groove, and first springs are fixed at equal intervals at the bottom of the pad, and one end of each first spring is in contact with one side of the sponge rod.

[0006] Preferably, multiple protective shells are fixedly provided at equal distances on both sides of the top of the linear guide body, and an oil inlet pipe is fixedly provided at the middle position of one side of the outer wall of the linear guide body, with one end of the oil inlet pipe passing through one side of the linear guide body and fixedly connected to one end of the sponge rod.

[0007] Preferably, each of the protective housings has an electric telescopic rod engaged on its inner wall, and multiple locking holes are equally spaced on both sides of the outer wall of the linear guide rail body, with the outer wall of the output end of each electric telescopic rod engaging with the inner wall of each locking hole.

[0008] Preferably, multiple support shafts are fixed at equal intervals on both sides of the bottom edge of the linear guide body, and a first screw hole is opened at the middle position of the top of each support shaft, and the outer wall of the bottom of the linear guide body is threadedly connected to the inner wall of the multiple first screw holes respectively.

[0009] Preferably, a second spring is sleeved on one end of the outer wall of each support shaft, a limiting base is fixedly provided at the bottom of each second spring, and the top of each second spring is fixedly connected to one side of the top of each support shaft. A second screw hole is provided at the four corners of the top of each limiting base.

[0010] Preferably, a switch panel is fixedly provided on one side of the outer wall of the linear guide rail body, and an electric telescopic rod switch is provided on one side of the switch panel, and the electric telescopic rod is electrically connected to an external power source through the electric telescopic rod switch.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This utility model features an automatic lubrication structure, which mainly consists of a through groove, a protective net, a mounting groove, a sponge rod, a pad, a first spring, and an oil tank. The sliding mechanism is installed on the upper end of the linear guide body to engage with the sliding groove to prevent it from falling off. As the guide block slides up and down, it squeezes the upper pad, causing the pad to press the first spring and squeeze out the lubricating oil from the sponge rod. The squeezed-out lubricating oil overflows into the two sliding grooves through the through groove. The protective net prevents too much lubricating oil from overflowing at once, providing sufficient lubrication between the linear guides. This eliminates the need for manual lubrication by operators, thus improving the practicality of the device.

[0013] This invention features a shock-absorbing mounting structure, primarily composed of a support shaft, a second spring, a limiting base, a first screw hole, and a second screw hole. During installation, the linear guide rail body is mounted on the inner wall of the shaft via the second screw hole at the upper end of the limiting base. As the guide block moves up and down, the linear guide rail body is compressed by the second spring and the support shaft, providing a certain degree of cushioning. The support shaft is interlocked with the inner wall on one side of the limiting base, creating a buffer space and reducing the risk of vibration and impact damage to the linear guide rail, thereby improving the safety of the device.

[0019] This utility model provides, for example Figure 1-3 The linear guide rail of a CNC machine tool with a self-lubricating structure shown includes a linear guide rail body 1. Multiple protective shells 9 are fixedly provided at equal distances on both sides of the top of the linear guide rail body 1. An oil inlet pipe 10 is fixedly provided at the middle position of one side of the outer wall of the linear guide rail body 1. One end of the oil inlet pipe 10 passes through one side of the linear guide rail body 1 and is fixedly connected to one end of a sponge rod 6. An electric telescopic rod 12 is engaged with the inner wall of each protective shell 9. Multiple locking holes 11 are opened at equal distances on both sides of the outer wall of the linear guide rail body 1. The outer wall of the output end of each electric telescopic rod 12 is engaged with the inner wall of each locking hole 11. A switch panel is fixedly provided on one side of the outer wall of the linear guide rail body 1. An electric telescopic rod switch is opened on one side of the switch panel. The electric telescopic rod 12 is electrically connected to an external power supply through the electric telescopic rod switch.

[0020] like Figure 2 As shown, both sides of the outer wall of the linear guide body 1 are provided with sliding grooves 2, and the middle position of one side of the inner wall of the two sliding grooves 2 is provided with through grooves 3. The inner walls of the two through grooves 3 are fitted with protective nets 4. The middle position of the inner wall of the linear guide body 1 is provided with an installation groove 5, and one end of the inner wall of the two through grooves 3 is connected to the inside of the installation groove 5. The upper end of the inner wall of the installation groove 5 is fitted with a pad 7, and the bottom of the inner wall of the installation groove 5 is fitted with a sponge rod 6. The bottom of the pad 7 is fixed with first springs 8 at equal distances, and one end of each first spring 8 is in contact with one side of the sponge rod 6.

[0021] like Figure 3As shown, multiple support shafts 13 are fixedly provided at equal intervals on both sides of the bottom edge of the linear guide body 1. A first screw hole is opened at the middle position of the top of each support shaft 13. The outer wall of the bottom of the linear guide body 1 is threadedly connected to the inner wall of the multiple first screw holes. A second spring 14 is sleeved on one end of the outer wall of each support shaft 13. A limiting base 15 is fixedly provided at the bottom of each second spring 14. The top of each second spring 14 is fixedly connected to one side of the top of each support shaft 13. A second screw hole is opened at each of the four corners of the top of each limiting base 15.

[0022] The working principle of this utility model is as follows: First, the sponge rod 6 at the upper end of the device needs to be engaged and installed in the mounting groove 5, so that it contacts the first spring 8. This allows the device to automatically add lubricating oil during use. In this design, an automatic lubrication structure is provided, consisting of a through groove 3, a protective net 4, a mounting groove 5, a sponge rod 6, a pad 7, a first spring 8, and an oil pipe 10. During use, the sliding mechanism at the upper end of the guide block is installed on the upper end of the linear guide rail body 1, engaging with the sliding groove 2 to prevent it from falling off. As the guide block slides up and down, it squeezes the upper pad 7, causing the pad 7 to press the first spring 8 and squeeze out the lubricating oil from the sponge rod 6. The squeezed-out lubricating oil overflows into the two sliding grooves 2 through the through groove 3, and the protective net 4 prevents the lubricating oil from overflowing. The overflow is sufficient for lubrication between the linear guides, eliminating the need for manual lubrication and improving the device's practicality. The device also features a shock-absorbing mounting structure consisting of a support shaft 13, a second spring 14, a limiting base 15, a first screw hole, and a second screw hole. During installation, the linear guide body 1 is mounted on the inner wall of the shaft via the second screw hole at the upper end of the limiting base 15. When the guide block rises and falls, the linear guide body 1 is compressed by the second spring 14 and the support shaft 13, providing a certain degree of cushioning. Furthermore, the support shaft 13 interlocks with the inner wall of the limiting base 15 on one side, creating a buffer space that reduces the risk of vibration and impact damage to the linear guide, thereby improving the safety of the device.
