Description

Technical Field

[0001] This invention belongs to the field of slider guide technology, and particularly relates to a slider guide structure for a horizontal machining center. Background Technology

[0002] Horizontal machining centers are core equipment in the field of precision machining, and the operational stability of their slide guide mechanism directly affects the overall machining accuracy and service life. During actual cutting processes, chips and foreign objects easily accumulate on the guide surface. Traditional chip removal structures often use fixed scrapers with poor self-adaptive contact, resulting in limited chip removal effectiveness and susceptibility to scratches and slide block jamming caused by hard foreign objects. Furthermore, existing slide guide lubrication methods are mostly external oil supply or periodic manual oil replenishment, which not only have small oil storage capacity and poor oil supply continuity, but also require disassembly of the slide and end cap assembly for oil replenishment, leading to cumbersome maintenance procedures, long downtime, and severely impacting machining efficiency. In addition, current chip removal and lubrication mechanisms are mostly independently set up, unable to work together, easily resulting in contamination of the lubrication surface during chip removal and residual oil film adhering to debris after lubrication, failing to meet the long-term, stable, high-efficiency, and low-maintenance requirements of horizontal machining centers.

[0003] There is an urgent need for improvement, so we propose a slider guide structure for horizontal machining centers. Summary of the Invention

[0010] Furthermore, the oil inlet assembly also includes a circular groove formed on the oil suction block, a sphere disposed in the circular groove, and a telescopic rod fixedly connected to the top of the inner cavity of the oil storage tank. The sphere has a hollow hole. A first spring is fixedly connected between the bottom end of the inner cavity of the circular groove and the sphere. A sealing plate is fixedly connected to one end of the telescopic rod near the through hole. A second spring is sleeved on the outer periphery of the telescopic rod. The two ends of the second spring are fixedly connected to the oil storage tank and the sealing plate, respectively.

[0011] Furthermore, the inner walls of the through hole and the oil inlet are arc-shaped and matched with the curvature of the outer surface of the sphere. The center of the sphere is placed in the circular groove. The sealing plate corresponds to the position of the through hole, and the diameter of the sealing plate is larger than the diameter of the through hole.

[0012] Furthermore, the connecting assembly includes rectangular grooves formed at both ends of each end cap and connecting plates fixedly connected to the connecting block near one end of each rectangular groove. Each connecting plate has a first fixing bolt rotatably passing through it, and the first fixing bolt is threadedly connected to the inner surface of the rectangular groove. Each connecting plate has a storage groove at the position corresponding to the head of the first fixing bolt, and the size of the storage groove is larger than the size of the head of the first fixing bolt.

[0023] Reference Figures 1 to 6 A slider guide rail structure for a horizontal machining center includes a guide rail 1 and a slider 2 slidably connected to the guide rail 1, wherein end caps 3 are installed at both ends of the slider 2, characterized in that it further includes: The protective mechanism includes connecting blocks 6 respectively located on the outside of each end cap 3. The connecting blocks 6 are connected to the end cap 3 through connecting components. The end of the connecting block away from the slider 2 is connected to a cleaning block 8 that is movably attached to the surface of the guide rail 1 through an elastic component. The cleaning block 8 slides synchronously with the slider 2 to remove chips and foreign objects from the upper surface of the guide rail 1. The lubrication mechanism includes an oil reservoir 4 located on the top of the connecting block 6 and oil filling grooves 33 located on opposite sides of the connecting block 6 and the cleaning block 8 on the same side. The oil reservoir 4 is connected to the end cap 3 via an installation assembly. An oil suction block 13 is provided between the oil filling grooves 33 on the same side. The oil suction block 13 is used to soak the lubricating oil and coat it on the surface of the guide rail 1. The oil reservoir 4 and the inner cavity of the oil filling grooves 33 of the connecting block 6 are connected by an oil inlet assembly for replenishing the lubricating oil.

[0024] This application integrates the protective mechanism and the lubrication mechanism on the outside of the end cover 3 of the slider 2. The cleaning block 8 can move and fit against the surface of the guide rail 1 and slide synchronously with the slider 2. It can remove chips and foreign objects from the upper surface of the guide rail 1 in real time during the operation of the slider 2, avoiding chip accumulation that could cause scratches on the guide rail 1 and jamming of the slider 2, thus ensuring smooth operation of the slider 2. The oil suction block 13 can be soaked in lubricating oil and continuously coated on the surface of the guide rail 1. Together with the oil tank 4 and the oil inlet component, it realizes automatic replenishment of lubricating oil without the need for frequent manual oil replenishment. At the same time, chip removal and lubrication work together to avoid chip contamination of the lubrication surface or the adhesion of debris to the oil film after lubrication. Structurally, it solves the problems of poor adaptability and cumbersome maintenance caused by the independent setting of chip removal and lubrication mechanisms, effectively improving the operational stability and processing quality of the slider 2 and guide rail 1, and extending the service life of the guide rail 1 and slider 2.

[0025] In the example of this application, the elastic component is an elastic sleeve 7. The two ends of the elastic sleeve 7 are respectively fixedly connected between the cleaning block 8 and the connecting block 6 on the same side. The elastic sleeve 7 is sleeved on the outer periphery of the oil-absorbing block 13. A notch 31 is opened at one end of the elastic sleeve 7 near the guide rail 1. A protrusion 12 is fixedly connected at one end of the oil-absorbing block 13 near the notch 31. The protrusion 12 is made of the same material as the oil-absorbing block 13 and is integrally formed. The protrusion 12 is in movable contact with the surface of the guide rail 1. The size of the protrusion 12 is adapted to the size of the notch 31.

[0026] As a preferred example of the present invention, the elastic sleeve 7 can effectively buffer the rigid impact when the cleaning block 8 contacts the stubborn debris on the surface of the guide rail 1, avoiding the impact load from acting directly on the cleaning block 8 and the guide rail 1, and preventing the components from deforming or breaking due to impact. The buffer deformation of the elastic sleeve 7 will simultaneously squeeze the inner oil-absorbing block 13, causing the lubricating oil soaked in the oil-absorbing block 13 to be squeezed out in a directional manner, increasing the discharge of lubricating oil, and ensuring that the surface of the guide rail 1 receives sufficient and timely lubrication. The elastic sleeve 7 is sleeved on the outer periphery of the oil-absorbing block 13, which can form reliable protection and positioning for the oil-absorbing block 13, preventing the oil-absorbing block 13 from shifting or loosening, and at the same time preventing the lubricating oil from leaking. With the notch 31 on the elastic sleeve 7 and the protrusion 12 integrally formed with the oil-absorbing block 13, the squeezed-out lubricating oil can be guided and evenly coated on the surface of the guide rail 1, ensuring that the oiling position is stable and the coating effect is reliable.

[0027] In the example of this application, the cleaning block 8 has a beveled portion 9 at the end away from the elastic sleeve 7, and the beveled portion 9 is inclined to one side of the guide rail 1 in the width direction.

[0028] As a preferred example of the present invention, the inclined surface 9 on the cleaning block 8 can guide and dredge the chips and foreign objects on the surface of the guide rail 1 during the sliding of the slider 2, guide the chips to the outside of the guide rail 1 in the width direction, avoid the chips from accumulating and squeezing at the front end of the cleaning block 8, reduce the direct impact between the chips and the cleaning block 8, reduce the risk of the cleaning block 8 getting stuck, and at the same time improve the smoothness of chip removal, and prevent the chips from remaining on the surface of the guide rail 1 and affecting the lubrication and sliding effect.

[0029] In the example of this application, the inner cavities of the cleaning block 8 and the connecting block 6 are both fixedly connected with oil scrapers 11, and each oil scraper 11 is in movable contact with the surface of the guide rail 1.

[0030] As a preferred example of the present invention, the oil scraper 11 in the inner cavity of the cleaning block 8 and the connecting block 6 can move synchronously with the slider 2 to scrape off excess lubricating oil from the surface of the guide rail 1 in real time, avoiding excessive overflow of lubricating oil and causing pollution. At the same time, it can scrape off fine debris adhering to the surface of the guide rail 1, preventing debris from mixing with the oil film and adhering to the guide rail 1, further purifying the surface of the guide rail 1, making the oiling operation of the oil-absorbing block 13 more uniform and effective, realizing the triple collaborative operation of cleaning debris, oiling, and scraping oil, and optimizing the working environment of the surface of the guide rail 1.

[0031] In the example of this application, the oil inlet assembly includes a through hole 32 at the bottom of the oil storage tank 4 and an oil inlet hole 28 at the top of the connecting block 6 and communicating with the oil licking groove on the connecting block 6. The position of the oil inlet hole 28 corresponds to that of the through hole 32 and the size is compatible.

[0032] As a preferred example of the present invention, the through hole 32 of the oil tank 4 is connected to the oil inlet hole 28 of the connecting block 6, and the lubricating oil can be stably circulated by gravity. No additional power components are required. The structure is simple and the operation is reliable. It can continuously replenish the lubricating oil to the oil filling tank 33 and the oil suction block 13, ensuring uninterrupted lubrication operation, avoiding dry friction wear of the guide rail 1 due to interruption of oil supply, and improving the continuity and stability of the lubrication mechanism.

[0033] In the example of this application, the oil inlet assembly further includes a circular groove 14 formed on the oil suction block 13, a ball 16 disposed in the circular groove 14, and a telescopic rod 29 fixedly connected to the top of the inner cavity of the oil storage tank 4. The ball 16 has a hollow hole 17. A first spring 15 is fixedly connected between the bottom end of the inner cavity of the circular groove 14 and the ball 16. A sealing plate 18 is fixedly connected to one end of the telescopic rod 29 near the through hole 32. A second spring 19 is sleeved on the outer periphery of the telescopic rod 29. The two ends of the second spring 19 are fixedly connected to the oil storage tank 4 and the sealing plate 18, respectively. The elastic force of the first spring 15 is greater than the sum of the weight of the ball 16, the elastic force of the second spring 19, the weight of the sealing plate 18, and the frictional force of the telescopic rod 29.

[0034] As a preferred example of the present invention, the oil inlet control structure, composed of the ball 16, the first spring 15, the telescopic rod 29, the second spring 19, and the sealing plate 18, allows the second spring 19 to drive the sealing plate 18 to seal the through hole 32 at the bottom of the oil tank 4 during the disassembly of the connecting block 6 or the oil tank 4. This effectively prevents leakage of lubricating oil inside the oil tank 4, eliminating the need to pre-extract the lubricating oil from the oil tank 4 before disassembly and significantly simplifying the disassembly and maintenance process. When the connecting block 6 and the oil tank 4 are assembled, the ball 16 can stably lift the sealing plate 18 by utilizing the fact that the elastic force of the first spring 15 is greater than the sum of the weight of the ball 16, the elastic force of the second spring 19, the weight of the sealing plate 18, and the frictional force of the telescopic rod 29. This allows the through hole 32 to communicate with the oil inlet 28, and the hollow hole 17 to facilitate the flow of oil.

[0035] In the example of this application, the inner walls of the through hole 32 and the oil inlet hole 28 are arc-shaped and are adapted to the curvature of the outer surface of the sphere 16. The center of the sphere 16 is placed in the circular groove 14. The sealing plate 18 is positioned corresponding to the through hole 32, and the diameter of the sealing plate 18 is larger than the diameter of the through hole 32.

[0036] As a preferred example of the present invention, the through hole 32 is adapted to the arc-shaped inner wall of the oil inlet hole 28 and the surface of the ball 16, and the center of the ball 16 is placed in the circular groove 14, thereby preventing the ball 16 from detaching from the through hole 32 and the oil inlet hole 28.

[0037] In the example of this application, the connecting assembly includes rectangular slots 27 formed at both ends of each end cap 3 and connecting plates 24 fixedly connected to one end of each rectangular slot 27 of the connecting block 6. Each connecting plate 24 has a first fixing bolt 26 rotatably passing through it, and the first fixing bolt 26 is threadedly connected to the inner surface of the rectangular slot 27. Each connecting plate 24 has a storage slot 25 at the position corresponding to the head of the first fixing bolt 26, and the size of the storage slot 25 is larger than the size of the head of the first fixing bolt 26.

[0038] As a preferred example of the present invention, the cooperation between the rectangular groove 27 and the connecting plate 24 can quickly realize the positioning and assembly of the connecting block 6 and the end cover 3. The threaded connection of the first fixing bolt 26 ensures a stable connection. The storage groove 25 can hide the head of the fixing bolt, avoiding the fixing bolt from protruding and affecting the operation of the slider 2 or causing interference. The overall connection structure is easy to disassemble and assemble, without disassembling the core components of the slider 2 and the end cover 3, simplifying the installation and maintenance process of the protective mechanism and reducing equipment downtime for maintenance.

[0039] In the example of this application, the mounting assembly includes threaded holes 23 on both sides of the end cap 3 away from the slider 2 and mounting tubes 20 fixedly connected to both sides of the inner cavity of the oil tank 4. The oil tank 4 is provided with second fixing bolts 10 on both sides of the end away from the end cap 3. Each second fixing bolt 10 is rotatably inserted through the oil tank 4 and placed in the inner cavity of the corresponding mounting tube 20. Each second fixing bolt 10 is threadedly screwed into the corresponding threaded hole 23.

[0040] As a preferred example of the present invention, the cooperation between the mounting tube 20 and the second fixing bolt 10 can securely install the oil tank 4 on the outside of the end cover 3. The threaded connection makes installation and disassembly simple, ensuring that the oil tank 4 does not loosen or fall off when the slider 2 slides at high speed, and also facilitating quick disassembly and replacement of the oil tank 4, greatly simplifying the maintenance operation of the lubrication mechanism and improving the equipment maintenance efficiency.

[0041] In the example of this application, an elastic sealing gasket 30 is fixedly connected to one end of the connecting block 6 near the oil tank 4, and an oil injection hole 21 communicating with its inner cavity is opened on one side of the top of the oil tank 4, and a sealing cap 5 is provided in the oil injection hole 21.

[0042] As a preferred example of the present invention, the elastic sealing gasket 30 can fill the assembly gap between the connecting block 6 and the oil tank 4 to prevent lubricating oil from leaking from the mating gap and ensure the overall sealing of the lubrication mechanism. The oil filling hole 21 on the top of the oil tank 4, in conjunction with the sealing cover 5, allows for the direct replenishment of lubricating oil without disassembling the oil tank 4, further simplifying the oil replenishment operation, improving the convenience of equipment use and maintenance, and reducing the time cost of downtime for oil replenishment.

[0043] It should be noted that the elastic sealing gasket 30 is made of nitrile rubber, which has excellent oil resistance, elasticity, and sealing properties. It can tightly fill the assembly gap, effectively prevent lubricating oil leakage, and can be used for a long time in the environment of cutting fluid and lubricating oil without aging or failure. The oil scraper 11 is made of polyurethane, which has good wear resistance and flexibility. It will not scratch the surface of the guide rail 1 during scraping and can stably scrape off excess lubricating oil and fine debris from the surface of the guide rail 1. It is not easily worn or deformed after long-term use. The oil-absorbing block 13 is made of wool felt, which has a porous adsorption structure. It can fully wet and store lubricating oil and can evenly release lubricating oil when squeezed, ensuring that the surface of the guide rail 1 is evenly coated with oil. It also has good oleophilicity and durability. The elastic sleeve 7 is made of oil-resistant nitrile rubber, which has good elastic deformation ability, cushioning performance, and oil and wear resistance. It can stably realize the functions of impact cushioning and compression oil supply. It is not easily aged or failed after long-term use in the environment of lubricating oil and cutting fluid. It also has good sealing performance and can prevent lubricating oil leakage.
