Description

Technical Field

[0001] This invention relates to the field of machining center technology, specifically to an inverted T-shaped moving column machining center. Background Technology

[0002] In existing technologies, vertical machining centers mainly adopt two structural forms: table-moving and column-moving. For machining scenarios involving large spans and heavy workpieces, the moving column structure, with its core advantage of a fixed table, has more suitable application characteristics.

[0003] However, traditional moving-column machine tools still face many technical challenges in practical applications. During milling and drilling operations, these machines continuously generate large amounts of metal cutting chips. If these chips are not cleaned promptly, they accumulate on the worktable, tool magazine, and workpiece clamping area, interfering with the continuity of core machine tool actions such as automated feed and tool changing, disrupting the normal machining rhythm. Furthermore, they easily enter the gaps of precision transmission components such as guideways and lead screws, causing scratches, wear, and even jamming, severely reducing the machine tool's positioning accuracy and service life. In contrast, existing chip removal structures mostly employ a single scraper or spiral design, with limited chip removal channel capacity and low chip removal efficiency. Moreover, due to structural layout limitations, they are difficult to adapt to the machining space requirements of large-span moving-column machine tools. When faced with high-intensity machining conditions of large workpieces, waste chips are very likely to get clogged in the chip removal channel, making it impossible to remove waste chips quickly and thoroughly. This leads to a significant reduction in the overall machining efficiency of the machining center, resulting in lower working efficiency.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] This embodiment provides an inverted T-shaped moving column machining center;

[0033] Please see Figure 1 - Figure 8As shown, the system includes a base 1, a movable column body 2 mounted on the base 1, a spindle box 3 mounted on the movable column body 2, a sliding saddle 4 mounted on the base 1, a machining table 5 mounted on the sliding saddle 4, and several through holes 6 in the center of the machining table 5. A chip collection groove 7 is located in the center of the base 1, with limit grooves 17 on both sides of the chip collection groove 7. A drive motor 8 is fixed to one side of the base 1, a fixing rod 9 is fixed to the drive end of the drive motor 8, and an auger rod 10 is fixed to the other end of the fixing rod 9. A auger blade 11 is fixed to the outer surface of the auger rod 10. A connecting structure is provided on one side of the fixing rod 9, and the connecting structure includes a guide frame 1. 2. A guide groove 13 is provided in the middle of the guide frame 12. A guide rod 14 is slidably connected to the inner wall of the guide groove 13. A sliding frame 15 is fixed at one end of the guide rod 14. Several grooves 16 are provided in the middle of the sliding frame 15. During processing, the base 1 serves as the support foundation of the whole machine. The moving column body 2 on it drives the spindle box 3 to complete the spatial position adjustment, so as to achieve precise cutting of the workpiece clamped on the processing table 5 above the slide saddle 4. The mixture of chips and cutting fluid generated during processing falls directly into the chip collection groove 7 of the base 1 through several through holes 6 in the middle of the processing table 5, providing a precondition for subsequent processing.

[0034] Please refer to it again. Figure 1 - Figure 8As shown, the guide frame 12 is fixed in the middle to the fixed rod 9 near the auger rod 10. The guide groove 13 is inclined and closed in the middle of the guide frame 12. The outer surface of the guide rod 14 is slidably connected to the inner wall of the guide groove 13. One end of the guide rod 14 is fixed to the middle of one side of the sliding frame 15. The vertical section of the sliding frame 15 is L-shaped. The outer surface of the sliding frame 15 is slidably connected to the inner wall of the limiting groove 17. Several grooves 16 are opened in the middle of the sliding frame 15. The outer surface of the sliding frame 15 is slidably connected to the inner wall of the chip collection groove 7. The outer surface of the fixed rod 9 is rotatably connected to the inner wall of the base 1. One end of the fixed rod 9 is fixed to the drive end of the drive motor 8. The other end of the fixed rod 9 is fixed to one end of the auger rod 10. The outer surface of the auger rod 10 is fixed to the inner wall of the auger blade 11. The outer surface of the auger blade 11 is slidably connected to the inner wall of the chip collection groove 7. The cooperation of the auger rod 10, the auger blade 11 and the sliding frame 15 constitutes an active conveying and feeding system. The coordinated chip removal mechanism of the active scraping achieves thorough cleaning of chips in the chip collection trough 7 without any dead angles. On one hand, the auger rod 10 drives the auger blades 11 to rotate, and with the axial thrust generated by the helical angle, it directionally transports a large amount of chips accumulated at the bottom of the chip collection trough 7, pushing the chips towards the collection area. On the other hand, the sliding frame 15, which is linked to the fixed rod 9, moves reciprocating linearly along the side wall of the chip collection trough 7 under the drive of the guide frame 12 and the guide rod 14. Its serrated grooves 16 can scrape and peel off stubborn chips adhering to the trough wall, causing the scraped chips to fall to the bottom of the trough. The fallen chips are then rolled into the conveying path by the rotating auger blades 11 and continuously transported together with the chips at the bottom of the trough. The two work together to form a dual cleaning effect of bottom conveying and side wall scraping, which not only avoids the local accumulation of chips in the trough, but also improves the comprehensiveness and efficiency of chip removal, ensuring the continuous and stable operation of the machining center.

[0035] The specific implementation process is as follows: The fixed rod 9 is driven by the drive motor 8 to rotate, which in turn drives the auger rod 10 fixed at the other end of the fixed rod 9 to rotate; the rotating auger rod 10 drives the auger blades 11 fixedly connected to its outer surface to rotate synchronously, and the spiral propulsion of the auger blades 11 is used to directionally transport the processing chips that fall into the chip collection groove 7 of the base 1 during the processing.

[0036] Meanwhile, the guide frame 12, which is fixedly connected to one side of the fixed rod 9, rotates coaxially with the fixed rod 9. The guide frame 12, through its inclined guide groove 13, forms a reciprocating pushing action on the guide rod 14, which is slidably connected in the groove. Under the constraint and limitation of the limiting grooves 17 on both sides of the chip collection groove 7, the sliding frame 15, which is fixedly connected to one end of the guide rod 14, slides reciprocally in a straight line along the length of the chip collection groove 7. The sliding frame 15 has several grooves 16 in the middle, forming a sawtooth structure. During the reciprocating sliding process, it can dynamically scrape off the processing chips adhering to the side wall of the chip collection groove 7, so that the scraped chips fall to the bottom of the chip collection groove 7. Finally, the chips at the bottom of the groove are transported to the subsequent collection area by the continuous conveying of the auger rod 10 and the auger blades 11, achieving a comprehensive and efficient cleaning effect of processing chips, avoiding chip accumulation that interferes with the processing process, thereby improving the overall working efficiency of the machining center.

[0037] Example 2

[0038] In existing machining centers, the chip removal system typically uses natural infiltration filtration to treat the cutting fluid mixed with waste chips during the cutting fluid recovery process, aiming to achieve cutting fluid recycling. However, this slow infiltration filtration method not only requires a long filtration cycle, preventing the cutting fluid from quickly returning to the reservoir for circulation, but also causes a delay in cutting fluid supply due to insufficient filtration efficiency. This, in turn, affects the continuous operation rhythm of the machining center and makes it difficult to meet the production demands of high-efficiency machining. Therefore, it is necessary to accelerate the filtration rate, shorten the cutting fluid recovery cycle time, and improve overall machining efficiency.

[0039] Please see Figure 1 - Figure 8 As shown, a dynamic filtering function has been added based on Embodiment 1;

[0040] Please refer to it again. Figure 1 - Figure 8As shown, a drive rod 18 is fixed to the other end of the auger rod 10. A filter collection rack 19 is slidably connected to the outer surface of the drive rod 18. A through groove 20 is opened on one side of the filter collection rack 19. Several filter holes 21 are opened in the middle of the filter collection rack 19. A support frame 22 is slidably connected to the outer surface of the filter collection rack 19. A drain groove 23 is opened on one side of the base 1. One end of the drive rod 18 is fixed to the side of one end of the auger rod 10. The outer surface of the drive rod 18 is slidably connected to the inner wall of the through groove 20. The through groove 20 passes through one side of the filter collection rack 19. A filter hole 21 penetrates the middle of the filter collection rack 19. The outer surface of the filter collection rack 19 contacts the inner wall of the support frame 22, and the outer surface of the filter collection rack 19 contacts one side of the outer surface of the base 1. One side of the support frame 22 is fixed to one side of the base 1. The drain groove 23 is inclined and penetrates the base 1 near the support frame 22. The vertical section of the support frame 22 is L-shaped. The reciprocating sliding filter collection rack 19 is the core structure for achieving efficient separation of cutting fluid and debris. Its dynamic sliding design completely breaks through the efficiency bottleneck of traditional static filtration. Driven by the combined action of the drive rod 18 and the through groove 20, the filter collection rack 19 moves steadily back and forth along the inner wall of the support frame 22. During this process, the filter holes 21 inside the rack are always in dynamic contact with the mixture of chips and cutting fluid transported by the auger. Compared with the fixed filtration method, this greatly increases the filtration contact area and effectively avoids filtration failure caused by local blockage of the filter holes 21. At the same time, the inertial impact force generated by the reciprocating sliding can cause the chips adhering to the surface of the filter collection rack 19 to fall off, reducing the probability of blockage of the filter holes 21 and maintaining a stable filtration rate. The filtered clean cutting fluid quickly flows through the filter holes 21 into the drain tank 23 and then into the collection tank 24 to participate in the circulation. The intercepted chips are evenly accumulated during the sliding process of the filter collection rack 19, avoiding excessive local accumulation that affects the filtration effect. This dynamic filtration mode not only improves the cutting fluid recovery efficiency and shortens the circulation cycle, but also, in conjunction with the subsequent stirring mechanism, provides a clean prerequisite for the stable circulation supply of cutting fluid. It forms an efficient linkage with the auger chip removal structure, ensuring the continuous operation of the machining center.

[0041] The specific implementation process is as follows: The drive motor 8 drives the fixed rod 9 to rotate, which in turn drives the auger rod 10, which is fixedly connected to the other end of the fixed rod 9, to rotate synchronously; the drive rod 18, which rotates coaxially with the auger rod 10, makes a circular motion with the central axis of the auger rod 10 as the center of rotation. The drive rod 18 passes through the through slot 20 opened on one side of the filter collection frame 19, and generates a reciprocating pushing and pulling force on the filter collection frame 19 during the circular rotation; under the limiting action of the inner wall of the support frame 22 on one side of the base 1, the filter collection frame 19 makes a reciprocating linear movement in the horizontal direction;

[0042] The reciprocating filter collection rack 19 dynamically filters and collects the mixture of chips and cutting fluid transported by the auger rod 10 and auger blades 11 through several filter holes 21 in its middle. The cutting fluid seeps out through the filter holes 21 and is discharged outside the support frame 22 area through the drain trough 23 on one side of the base 1, achieving rapid recovery. The machining chips are intercepted by the filter holes 21 and remain inside the filter collection rack 19. When it is necessary to clean the collected chips, the filter collection rack 19 can be removed and emptied simply by pulling it upwards. This structure achieves dynamic filtration through the reciprocating movement of the filter collection rack 19, significantly improving filtration efficiency, shortening the cutting fluid recovery cycle time, and thus improving the overall machining efficiency of the machining center.

[0043] Example 3

[0044] Because cutting fluids are prone to oil-water separation and component sedimentation during static storage, current technology requires an additional independent stirring motor to continuously agitate the collected cutting fluid to maintain its compositional uniformity. This method not only increases the equipment purchase and maintenance costs of the machining center but also consumes additional electricity due to the continuous operation of the stirring motor, raising the overall operating cost. Therefore, it is necessary to rely on existing power sources, thereby eliminating the need for an additional power source and effectively reducing the construction and operating costs of the machining center.

[0045] Please see Figure 1 - Figure 8 As shown, the automatic homogenization function of the cutting fluid has been added based on Example 1;

[0046] Please refer to it again. Figure 1 - Figure 8As shown, a collection tank 24 is provided at the other end of the drainage tank 23, and a through groove 25 is provided at the other end of the collection tank 24. A liquid outlet connection flange 26 is fixed on one side of the collection tank 24. Rotating frames 27 are rotatably connected to both sides of the collection tank 24. Several agitators 28 are fixed in the middle of each rotating frame 27. Driven wheels 29 are fixed on one side of each of the two rotating frames 27. The two driven wheels 29 are connected to the driving wheel 30 through a synchronous belt. The two ends of the two rotating frames 27 are rotatably connected to the inner walls of both sides of the collection tank 24. The middle of the two rotating frames 27 is fixed to the middle of several agitators 28. The vertical cross-section of each agitator 28 is cross-shaped. The middle of the two rotating frames 27 is fixed to the middle of two driven wheels 29. The two driven wheels 29 are connected to the driving wheel 30 through a synchronous belt. The middle of the driving wheel 30 is fixed. In the middle of the fixed rod 9, the rotating agitator 28, powered by the drive motor 8, rotates synchronously with the rotating frame 27, achieving thorough agitation of the cutting fluid in the collection tank 24. During its rotation, the blades continuously break the static state of the cutting fluid, effectively preventing oil-water separation and additive sedimentation, ensuring uniform composition and stable performance of the cutting fluid. At the same time, the fluid flow generated by the agitation accelerates the cooling of the cutting fluid, preventing deterioration due to residual heat from machining and extending its service life. Furthermore, the agitator 28 requires no additional power source and forms a highly efficient linkage with the front-end dynamic filtration structure, ensuring that the cutting fluid entering the circulation system is always in a high-quality state, providing reliable protection for lubrication and cooling in subsequent machining, further improving the operational stability of the machining center, and reducing equipment operating costs.

[0047] The specific implementation process is as follows: The drive motor 8 drives the fixed rod 9 to rotate, which in turn drives the drive wheel 30, which is fixedly connected to the middle of the fixed rod 9, to rotate synchronously. The drive wheel 30 drives the driven wheel 29 to rotate coaxially through the transmission action of the synchronous belt. The rotating frame 27, which is fixedly connected to the middle of the driven wheel 29, rotates synchronously with the driven wheel 29 under the limitation of the inner wall of the liquid collection tank 24. The two sets of rotating frames 27 drive several agitator frames 28, which are fixedly connected to the middle of the frame, to rotate synchronously, so as to continuously agitate the cutting fluid discharged into the liquid collection tank 24 through the drain tank 23, effectively avoiding the problems of oil-water separation and component sedimentation of the cutting fluid.

[0048] The fluid replenishment operation can be completed through the through-slot 25 at the other end of the collection tank 24. By connecting the cutting fluid delivery pipeline to the outlet flange 26, the cutting fluid can be circulated and supplied. This structure relies on the existing power source, the drive motor 8, to complete the agitation operation, eliminating the need for an additional independent agitator motor. This achieves automatic homogenization of the cutting fluid and saves on the purchase and maintenance costs of additional power equipment, ultimately reducing the overall cost and operating cost of the machining center.
