Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a slant bed turning and milling composite CNC machine tool. Background Technology

[0002] Slant bed CNC lathes are high-precision, high-efficiency automated machine tools. Equipped with multi-station turrets or power turrets, these machines offer a wide range of machining capabilities, capable of processing complex workpieces such as straight cylinders, slanted cylinders, arcs, and various threads, grooves, and worm gears. They also feature linear interpolation, circular interpolation, and various compensation functions, demonstrating excellent economic benefits in the mass production of complex parts.

[0003] Patent application CN202322859144.X discloses a slant bed turning and milling composite CNC machine tool, including a machine tool body and a machine tool protective cover. The machine tool body includes a bed, a spindle assembly mounted on the bed, a tailstock slide rail mounted on the bed, a tailstock assembly mounted on the tailstock slide rail, and a worktable mounted on the bed. The worktable includes an X-axis guide rail, a saddle, a right slide cover, and a left slide cover mounted on the X-axis guide rail, a Z-axis guide rail mounted on the saddle, a tool post mounted on the Z-axis guide rail, a tool post guard mounted on the tool post, and scrapers on both sides of the tool post guard. The right and left slide covers prevent waste chips from falling onto the bed, the tool post guards prevent waste chips from accumulating on the tool post and the Z-axis guide rail, and the lead screw guard prevents waste chips from adhering to the lead screw. The two scrapers collect waste chips from the left and right slide covers according to the movement of the tool post.

[0004] Compared with the above documents, the slant bed turning and milling composite CNC machine tool collects waste chips through a scraper. During the use of CNC machine tools, cutting fluid is sometimes used. During the turning and milling process, waste chips will mix with metal scraps, which is not convenient for separating, recycling and reusing metal scraps and cutting fluid. Utility Model Content

[0005] This utility model discloses a slant bed turning and milling composite CNC machine tool, which aims to solve the technical problem that cutting fluid is sometimes used in the use of CNC machine tools, and that waste chips are mixed with metal shavings during the turning and milling process. The mixing of cutting fluid and waste chips affects the subsequent recycling and reuse.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A slant bed milling and turning composite CNC machine tool includes a machine tool body. A slot is formed on the upper front side of the machine tool body. A liquid storage tank is formed inside the machine tool body at the lower end of the slot. A partition is installed at the front end of the liquid storage tank. A storage groove is formed inside the machine tool body at the front end of the partition. Limiting grooves are formed at both ends of the slot. A second lead screw is rotatably connected inside the limiting groove. A first slider is rotatably connected to the outer rear end of the second lead screw. A second slider is rotatably connected to the outer side of the second lead screw at the front end of the first slider. A baffle is fixedly installed between the first sliders. A receiving plate is rotatably connected to the lower front side of the baffle. A rotating shaft is rotatably connected to the second slider via a bearing. A flexible brush block is fixedly installed on the outer side of the rotating shaft. A receiving strip is welded to the middle of the storage groove and the middle of the front end of the partition. A storage box is connected to the upper end of the receiving strip. A filter plate is connected to the upper end of the partition.

[0008] By setting up a filter plate and a collection box, the cutting fluid used during milling and turning falls into the storage tank through the filter plate, while the metal chips generated during milling and turning remain on the filter plate, facilitating the separation of the cutting fluid and metal chips. Then, through the cooperation of the second lead screw and the first slider, as the receiving plate slides, it works with the flexible brush block to brush the metal chips onto the receiving plate during the sliding process. The metal chips are then poured into the collection box for easy collection and subsequent recycling.

[0009] In a preferred embodiment, a first slide groove is provided at the upper rear end of the machine tool body, a first lead screw is rotatably connected inside the first slide groove, a slide table is rotatably connected outside the first lead screw, a second slide groove is provided on the left side of the slide table, a fixed block is slidably connected inside the second slide groove, a spring is provided between the second slide groove and the fixed block, and a cleaning brush is fixedly installed on the side of the fixed block near the central axis.

[0010] By setting a fixed block in conjunction with a spring, when the first lead screw drives the slide table to slide, the spring will cause the cleaning brush to stick tightly to the first lead screw. The cleaning brush will brush off the metal debris that falls on the surface of the first lead screw, preventing the debris from affecting the operation of the first lead screw.

[0011] In a preferred embodiment, the lower end of the partition has a through groove, the lower end of the storage box has a leakage groove, the lower end of the filter plate is fixedly installed with a locking strip, the front end of the filter plate has a first groove, a locking block is fixedly installed in the first groove, the upper front side of the filter plate has a second groove, a locking strip is rotatably connected inside the second groove, the upper end of the partition has a locking groove, and the upper rear side of the liquid storage tank is fixedly installed with a receiving block.

[0012] By setting up a through groove and a drain groove, after the metal scraps are collected into the storage box, the moisture on the surface of the metal scraps will leak out from the drain groove and enter the liquid storage tank through the through groove, which facilitates the collection of cutting fluid. Through the cooperation of the first groove and the second groove, after the filter plate is placed on the partition, the locking strip is rotated to lock the block, which improves the stability of the filter plate installation.

[0013] As can be seen from the above, the slant bed milling and turning composite CNC machine tool provided by this utility model uses the rotation of flexible brush blocks to sweep metal debris on the filter plate onto the receiving plate, thereby cleaning the filter plate. This not only avoids clogging of the filter plate but also facilitates the collection of metal debris, making it easier to separate and collect the metal debris from the cutting fluid. This facilitates the subsequent recycling of the metal debris and cutting fluid, avoiding the need for separation work only during recycling. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] The slant bed turning and milling composite CNC machine tool disclosed in this utility model is mainly used in scenarios where cutting fluid is sometimes used in the operation of CNC machine tools. During the turning and milling process, the waste chips will be mixed with metal fragments. The mixing of cutting fluid and waste chips will affect the subsequent recycling and reuse.

[0024] Reference Figure 1 , Figure 2 and Figure 5 A slant bed milling and turning composite CNC machine tool includes a machine tool body 1. A slot 2 is formed on the upper front side of the machine tool body 1. A liquid storage tank 6 is formed inside the machine tool body 1 at the lower end of the slot 2. A partition 7 is installed at the front end of the liquid storage tank 6. A receiving slot 8 is formed inside the machine tool body 1 at the front end of the partition 7. Limiting slots 10 are formed at both ends of the slot 2. A second lead screw 11 is rotatably connected inside the limiting slot 10. A first slider 12 is rotatably connected to the outer rear end of the second lead screw 11. A second slider 13 is rotatably connected to the outer side of the rod 11 at the front end of the first slider 12. A baffle 14 is fixedly installed between the first sliders 12. A receiving plate 15 is rotatably connected to the front side of the lower end of the baffle 14. A rotating shaft 16 is rotatably connected to the second slider 13 through a bearing. A flexible brush block 17 is fixedly installed on the outer side of the rotating shaft 16. A receiving strip 18 is welded to the middle of the inside of the storage groove 8 and the middle side of the front end of the partition 7. A storage box 19 is connected to the upper end of the receiving strip 18. A filter plate 21 is connected to the upper end of the partition 7.

[0025] In this embodiment: When the machine tool body 1 is in use, cutting fluid is sometimes used. When the mixture of cutting fluid and metal chips falls onto the filter plate 21, the cutting fluid falls directly into the storage tank 6, while the metal chips fall onto the filter plate 21 and are trapped by the filter plate 21. The motor drives the second lead screw 11 to rotate, which in turn drives the first slider 12 and the second slider 13 to slide. The sliding of the first slider 12 causes the baffle 14 and the receiving plate 15 to slide. At the same time, the motor on the left side of the second slider 13 starts, which drives the rotating shaft 16 to rotate. The rotation of the rotating shaft 16 causes the flexible brush block 17 installed on the rotating shaft 16 to rotate. The rotation of the flexible brush block 17... The metal debris on the filter plate 21 is swept onto the receiving plate 15 to clean the filter plate 21. This not only prevents the filter plate 21 from becoming clogged, but also facilitates the collection of metal debris. As the second lead screw 11 rotates, the baffle 14 slides to the upper end of the collection groove 8. Due to gravity, the receiving plate 15 rotates downward, pouring the metal debris on the receiving plate 15 into the collection box 19 on the receiving strip 18 in the collection groove 8. This facilitates the centralized collection of metal debris, the recycling and reuse of metal debris, and the separation and collection of metal debris from cutting fluid. This facilitates the subsequent recycling and reuse of metal debris and cutting fluid, avoiding the need for separation work only during recycling.

[0026] Reference Figure 1 and Figure 6 In a preferred embodiment, a first slide groove 3 is provided at the upper rear end of the machine tool body 1. A first lead screw 4 is rotatably connected inside the first slide groove 3. A slide table 5 is rotatably connected outside the first lead screw 4. A second slide groove 29 is provided on the left side of the slide table 5. A fixing block 30 is slidably connected inside the second slide groove 29. A spring 31 is provided between the second slide groove 29 and the fixing block 30. A cleaning brush 32 is fixedly installed on the side of the fixing block 30 near the central axis.

[0027] In this embodiment, when the CNC machine tool is in use, the first lead screw 4 will rotate and drive the slide table 5 to slide to realize the milling of metal parts. The spring 31 will press the fixing block 30 in the second slide groove 29, so that the cleaning brush 32 on the fixing block 30 contacts the first lead screw 4. As the slide table 5 slides, it will clean the surface of the first lead screw 4, preventing metal debris from adhering to the surface of the first lead screw 4 and affecting the operation of the first lead screw 4, thereby improving the stability of the machine tool body 1 during milling.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In a preferred embodiment, the lower end of the partition 7 is provided with a through groove 9, the lower end of the storage box 19 is provided with a leakage groove 20, the lower end of the filter plate 21 is fixedly installed with a retaining strip 22, the front end of the filter plate 21 is provided with a first groove 23, a retaining block 24 is fixedly installed in the first groove 23, the upper front side of the filter plate 21 is provided with a second groove 25, a locking strip 26 is rotatably connected inside the second groove 25, the upper end of the partition 7 is provided with a retaining groove 27, and the upper rear side of the liquid storage tank 6 is fixedly installed with a receiving block 28.

[0029] In this embodiment: After metal scrap falls into the collection box 19, the residual cutting fluid on the metal scrap accumulates at the bottom of the collection box 19 over time. The cutting fluid is discharged into the collection box 19 through the drain 20. The collection groove 8 set at the bottom inclined platform discharges the cutting fluid into the storage tank 6 through the through groove 9, further improving the separation degree of metal scrap and cutting fluid. When installing the filter plate 21, one end of the filter plate 21 is placed on the receiving block 28, and the locking strip 22 on the filter plate 21 is aligned with the locking groove 27 and pressed down. After the filter plate 21 is installed, the locking strip 26 in the second groove 25 is rotated to lock the locking block 24 in the first groove 23, improving the stability of the filter plate 21 installation and preventing the filter plate 21 from shifting due to vibration generated during milling, thereby affecting the separation of cutting fluid and metal scrap.
