Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 - Figure 12 , a column of a precision horizontal machining center, including a horizontal base 1, a vertical base 2 is installed on the outside of the horizontal base 1, a column body 3 is installed on the top of the vertical base 2, a lubrication assembly 4 is provided on the outer wall of the column body 3, a moving seat 5 is installed on the outer wall of the column body 3, an oil drain assembly 6 is provided on the outer wall of the column body 3, a sliding seat 7 is fixedly assembled at the bottom of the column body 3, and a spindle box 8 is fixedly assembled on the outer wall of the moving seat 5; In the above structure, by providing the column body 3 on the top of the vertical base 2, the column body 3 can be adjusted in the front - rear direction on the top of the vertical base 2, and by installing the moving seat 5 on the outer wall of the column body 3, the moving seat 5 can move up and down along the outer wall of the column body 3, so as to perform cutting processing on the workpiece, thereby achieving the corresponding production and processing effect.

[0021] In a preferred embodiment: The lubrication assembly 4 includes a limit rail 401. A storage groove 402 is formed in the inner cavity of the limit rail 401, and a release groove 403 is formed in the inner cavity of the limit rail 401. A limit rod 404 is fixedly assembled on the inner wall of the release groove 403. A moving plate 405 is movably sleeved on the outer wall of the limit rod 404, and a return spring 406 is movably sleeved on the outer wall of the limit rod 404. A blocking plate 407 is fixedly assembled on the outer wall of the moving plate 405. A moving plug 408 is movably sleeved in the inner cavity of the storage groove 402. A rotating plate 409 is rotatably connected to the bottom of the moving plug 408, and a limit bracket 4010 is fixedly assembled at the bottom of the moving plug 408; In the above structure, through the storage groove 402 and the release groove 403 formed in the inner cavity of the limit rail 401, by injecting grease into the inner cavities of the release groove 403 and the storage groove 402, during the process of the moving plug 408 moving downward along the inner wall of the limit rail 401, it can play a role in squeezing the grease in the inner cavities of the storage groove 402 and the release groove 403, so that the grease pushes the moving plate 405 and the blocking plate 407 to move, causing the moving plate 405 to move outward from the limit rail 401. At this time, the grease in the inner cavity of the limit rail 401 will move out from the inner cavity of the release groove 403, so that the grease contacts the outer wall of the limit rail 401, thereby realizing the lubrication of the outer wall of the limit rail 401 under the action of the grease and ensuring that the moving seat 5 can run stably on the outer wall of the limit rail 401.

[0022] In a preferred embodiment: A fixed rod 4011 is fixedly assembled at the top of the moving plug 408, and a piston plate 4012 is fixedly assembled at the top of the fixed rod 4011. An air guide cylinder 4013 is installed at the top of the column body 3. A connecting pipe 4014 is fixedly assembled at the top of the air guide cylinder 4013. A driving cylinder 4015 is fixedly assembled on the outer wall of the column body 3. A driving plate 4016 is movably sleeved in the inner cavity of the driving cylinder 4015. A driving rod 4017 is fixedly assembled at the top of the driving plate 4016, and an electromagnet 4018 is fixedly assembled at the top of the driving rod 4017. A permanent magnet 4019 is fixedly assembled on the outer wall of the moving seat 5. An oil injection screw 4020 is threadedly connected to the outer wall of the limit rail 401; In the above structure, through the provided driving cylinder 4015 and the driving plate 4016 arranged in the inner cavity of the driving cylinder 4015, when it is necessary to lubricate the outer wall of the limiting rail 401, the position of the moving seat 5 is adjusted to the middle position of the limiting rail 401. By energizing the electromagnet 4018 to generate magnetism, at this time, the electromagnet 4018 will adsorb the permanent magnet 4019, enabling the driving rod 4017 and the moving seat 5 to move synchronously. At this time, when the moving seat 5 moves downward, it will drive the driving rod 4017 and the driving plate 4016 to move downward, thereby squeezing the air in the inner cavity of the driving cylinder 4015. The air in the inner cavity of the driving cylinder 4015 will enter the air guide cylinder 4013 along the connecting pipe 4014, thereby driving the piston plate 4012 and the moving plug 408 in the air guide cylinder 4013, causing the moving plug 408 to move downward along the inner cavity of the limiting rail 401, thereby squeezing the grease in the inner cavity of the limiting rail 401, causing the grease to overflow and then come into contact with the outer wall of the limiting rail 401.

[0023] In a preferred embodiment: the outer wall diameter of the moving plug 408 matches the inner wall diameter of the storage groove 402. The two ends of the outer wall of the return spring 406 are respectively in contact with the outer wall of the moving plate 405 and the inner wall of the release groove 403, and the return spring 406 is made of high-carbon steel. The angle by which the rotating plate 409 rotates downward is thirty degrees. In the above structure, through the moving plug 408 arranged in the inner cavity of the limiting rail 401, when the moving plug 408 moves downward, the rotating plate 409 will fit against the bottom of the moving plug 408, thereby squeezing the grease. When the moving plug 408 moves upward along the limiting rail 401, the rotating plate 409 will rotate downward under the action of gravity. At this time, as the moving plug 408 moves, the grease in the horizontal base 1 in the inner cavity of the limiting rail 401 will not be sucked upward, ensuring that the grease in the limiting rail 401 can be squeezed during the downward movement of the moving plug 408, and the grease will not be affected by the upward movement of the moving plug 408, enabling the grease to better lubricate the outer wall of the limiting rail 401.

[0024] In a preferred embodiment: the outer wall diameter of the piston plate 4012 matches the inner wall diameter of the air guide cylinder 4013. The two ends of the connecting pipe 4014 are respectively connected to the air guide cylinder 4013 and the driving cylinder 4015, and the connecting pipe 4014 is made of natural rubber. The number of driving cylinders 4015 is two, and the two driving cylinders 4015 are respectively installed on both sides of the outer wall of the column body 3. In the above structure, the driving cylinder 4015 is connected to the air guide cylinder 4013 under the action of the connecting pipe 4014. After the electromagnet 4018 is energized, it can attract the permanent magnet 4019, so that the driving rod 4017 can move with the up and down movement of the moving seat 5, thus realizing the driving of the driving plate 4016. When the moving seat 5 moves downward, the gas in the inner cavity of the driving cylinder 4015 can be squeezed, so that the gas in the driving cylinder 4015 will enter the air guide cylinder 4013 along the connecting pipe 4014, thereby driving the piston plate 4012 in the air guide cylinder 4013, making the piston plate 4012 move downward along the inner wall of the air guide cylinder 4013, thus realizing the driving of the moving plug 408 and squeezing the grease in the limiting rail 401.

[0025] In a preferred embodiment: The oil discharging assembly 6 includes a fixed pipe 601, an oil storage pipe 602 is fixedly assembled on the outer wall of the fixed pipe 601, an oil storage cylinder 603 is fixedly assembled at the bottom of the oil storage pipe 602, a release pipe 604 is fixedly assembled on the outer wall of the oil storage cylinder 603, a support plate 605 is installed on the outer wall of the column body 3, a movable rod 606 is movably sleeved in the inner cavity of the fixed pipe 601, a movable plug 607 is fixedly assembled at the top of the movable rod 606, and a lifting plug 608 is fixedly assembled at the bottom of the movable rod 606; In the above structure, through the arranged fixed pipe 601, and the two ends of the fixed pipe 601 are respectively communicated with the air guide cylinder 4013, the gas in the driving cylinder 4015 can enter the fixed pipe 601 along the limiting rod 404, so that the gas enters the fixed pipe 601. At this time, the gas can drive the movable plug 607 in the inner cavity of the fixed pipe 601, making the movable plug 607 move downward along the inner cavity of the fixed pipe 601, thus realizing the pushing of the lifting plug 608. Under the action of the lifting plug 608, the grease in the oil storage pipe 602 and the oil storage cylinder 603 is squeezed into the release pipe 604 and released along the release pipe 604 to the bottom of the column body 3 to lubricate the contact track between the longitudinal base 2 and the column body 3, ensuring the stable operation of the column body 3.

[0026] In a preferred embodiment: A rotating plate 409 is rotatably connected to the bottom of the lifting plug 608, a limiting frame 4010 is fixedly assembled at the bottom of the lifting plug 608, and the outer wall diameter of the movable plug 607 matches the inner wall diameter of the fixed pipe 601; In the above structure, through the lifting plug 608 arranged in the inner cavity of the oil storage pipe 602, when the lifting plug 608 moves downward along with the movable plug 607, similarly, the rotating plate 409 will fit against the bottom of the lifting plug 608 to extrude the grease, so that the grease is released outward through the release pipe 604. Subsequently, when the movable plug 607 moves upward, the rotating plate 409 will rotate downward, thus preventing the lifting plug 608 from sucking the grease in the inner cavity of the oil storage cylinder 603 upward when moving upward.

[0027] In a preferred embodiment: The outer wall of the oil storage cylinder 603 is threadedly connected with an oil injection screw 4020, and the outer wall diameter of the lifting plug 608 is equal to the inner wall diameter of the oil storage cylinder 603; In the above structure, through the oil injection screws 4020 arranged on the outer walls of the oil storage cylinder 603 and the limiting rail 401, by removing the oil injection screws 4020 from the outer walls of the oil storage cylinder 603 and the limiting rail 401 respectively, grease can be injected into the inner cavities of the oil storage cylinder 603 and the limiting rail 401 respectively. And when injecting grease, the moving plug 408 and the lifting plug 608 are respectively at the tops of the limiting rail 401 and the oil storage pipe 602, so that there is enough space in the storage groove 402 and the oil storage pipe 602 to inject grease.

[0028] In a preferred embodiment: The inner cavity volume of the driving cylinder 4015 is larger than the sum of the inner cavity volumes of the air guide cylinder 4013 and the oil storage pipe 602. The outer wall of the air guide cylinder 4013 is connected to the outer wall of the fixed pipe 601, and the inner cavity of the air guide cylinder 4013 is communicated with the inner cavity of the fixed pipe 601; In the above structure, through the driving cylinder 4015 arranged on the outer wall of the column body 3, when it is necessary to lubricate the outer wall of the limiting rail 401, the movement track of the moving seat 5 starts from the middle of the limiting rail 401 and moves downward. After the bottom of the moving seat 5 touches the top of the column body 3, the moving seat 5 moves upward. After the moving seat 5 moves upward to the middle of the limiting rail 401, the entire action of extruding grease is completed. At this time, the electromagnet 4018 stops power supply, and the electromagnet 4018 is disconnected from the permanent magnet 4019. During the entire process of extruding grease, the blocking plate 407 will not affect the movement of the moving seat 5.

[0029] In a preferred embodiment: The outer wall shape of the limiting rail 401 matches the outer wall shape of the moving seat 5. The piston plate 4012 is made of natural rubber, and the inner wall diameter of the storage groove 402 is larger than the inner wall diameter of the release groove 403; In the above structure, through the limiting rail 401 provided on the outer wall of the column body 3, the moving seat 5 can move along the outer wall of the limiting rail 401. After the grease in the inner cavity of the limiting rail 401 is extruded, it can contact the outer wall of the limiting rail 401. Subsequently, with the movement of the moving seat 5, during the entire operation of the moving seat 5 along the limiting rail 401, the lubricant is fully applied to the outer wall of the limiting rail 401, thereby ensuring a better lubrication effect on the outer wall of the limiting rail 401.

[0030] Working principle: During the use of the above device, when lubrication is required regularly for the device, the position of the moving seat 5 is adjusted to the middle of the limiting rail 401. Subsequently, by supplying power to the electromagnet 4018, the magnetic force of the electromagnet 4018 is increased. After the magnetic force of the electromagnet 4018 is increased, the electromagnet 4018 and the permanent magnet 4019 are synchronized. At this time, the moving seat 5 is at the middle position of the limiting rail 401. Then, the moving seat 5 moves downward from the middle of the limiting rail 401. As the moving seat 5 moves downward, it will drive the permanent magnet 4019 to move downward. When the permanent magnet 4019 moves downward, it will drive the electromagnet 4018 and the driving rod 4017 to move downward, thereby pushing the driving plate 4016 to move, squeezing the gas in the inner cavity of the driving cylinder 4015, so that the gas enters the connecting pipe 4014 from the driving cylinder 4015 and enters the air guide cylinder 4013 along the connecting pipe 4014, driving the piston plate 4012 in the inner cavity of the air guide cylinder 4013, and thus pushing the moving plug 408 downward under the action of the piston plate 4012 and the fixed rod 4011. Under the action of the moving plug 408, the grease in the inner cavity of the limiting rail 401 is squeezed. Under the action of the grease, the blocking plate 407 is pushed to move, so that the blocking plate 407 moves outward. At this time, the grease in the inner cavities of the storage tank 402 and the release tank 403 will be squeezed out, so that the grease is released to the outer wall of the limiting rail 401. After the air in the inner cavity of the connecting pipe 4014 is released into the air guide cylinder 4013, it will enter the fixed pipe 601 and drive the movable plug 607 and the lifting plug 608, so that the grease in the inner cavities of the oil storage pipe 602 and the oil storage cylinder 603 is squeezed into the release pipe 604 and is released along the release pipe 604 to the outer wall of the sliding seat 7, playing a role in lubricating the top of the sliding seat 7 and the longitudinal base 2. During the process of squeezing the grease, the moving seat 5 moves downward from the middle of the limiting rail 401 to the top of the limiting rail 401, completing the lubrication of the outer wall of the limiting rail 401 and the outer wall of the sliding seat 7. Subsequently, the moving seat 5 moves upward along the outer wall of the limiting rail 401. When the moving seat 5 moves upward, the driving cylinder 4015 will draw back the gas in the inner cavities of the air guide cylinder 4013 and the fixed pipe 601, so that the moving plug 408 and the lifting plug 608 move upward along the inner cavities of the storage tank 402 and the oil storage pipe 602 respectively. And during the upward movement of the lifting plug 608 and the moving plug 408, the grease in the inner cavities of the storage tank 402 and the oil storage pipe 602 will not be drawn upward, completing the entire action of squeezing the grease. At this time, the moving seat 5 moves upward from the bottom of the limiting rail 401 to the middle of the limiting rail 401. Then, the power supply to the electromagnet 4018 is stopped, so that the connection between the electromagnet 4018 and the permanent magnet 4019 is disconnected. At this time, the moving seat 5 can move up and down normally. And after the blocking plate 407 completes the release of the grease, after the moving plug 408 moves upward, the pressure acting on the blocking plate 407 will decrease.Under the action of the reset spring 406, the blocking plate 407 will fit against the outer wall of the limiting rail 401 and will not affect the normal movement of the moving seat 5. After disconnecting the electromagnet 4018 from the permanent magnet 4019, the moving seat 5 can move up and down normally. Apply the grease on the outer wall of the limiting rail 401 evenly to ensure the normal and stable operation of the column body 3, so that the lubrication effect of the outer wall of the limiting rail 401 and the outer wall of the sliding seat 7 is good.
