[0002] The double-column double-channel CNC vertical lathe has two columns and two processing channels, which can process workpieces simultaneously or separately. This design greatly improves processing efficiency and flexibility, and is particularly suitable for occasions that require large-scale, high-precision processing. For example, for flange processing, the two spindles can process the inner and outer rings of the flange at the same time, greatly improving processing efficiency.

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1: Reference Figure 1-Figure 3 , a vertical lathe, which is used in the field of mechanical processing equipment, is mainly composed of a lathe body, a processing structure, a protective structure and a chip removal structure. The lathe body includes a base 1 and a protective cover 2 fixed on the top of the base 1. Two movable doors 31 arranged up and down are provided on one side of the protective cover 2, which are used to open or close during the processing process to facilitate the loading and unloading of the workpiece. Two L-shaped limit strips 32 are fixed to the corresponding positions of the protective cover 2, and the movable door 31 slides between the two L-shaped limit strips 32 to ensure the stability of the movement.

[0047] Reference Figure 1 and Fig. 9 Two pins 36 are slidably inserted into the L-shaped limit strip 32 at the bottom, and the two pins 36 are used to brake the movable door 31. A plurality of pin holes 33 are provided at the bottom of the movable door 31, and when the pins 36 are inserted into the corresponding pin holes 33, the movable door 31 is locked.

[0048] Reference Figure 3 and Figure 4, the processing structure is arranged on the U-shaped frame 5, and the U-shaped frame 5 is fixed on the top of the base 1. Two spindles 12 are arranged on one side of the U-shaped frame 5, and a tool is installed on the bottom end of each spindle 12 through a tool holder. In order to realize the precise movement of the spindle 12, two rectangular grooves are arranged on one side of the U-shaped frame 5, in which a guide rod 7 is installed, and in the other rectangular groove a first screw rod 6 is rotatably connected. The cross frame 8 is slidably connected to one side of the U-shaped frame 5, the guide rod 7 is slidably connected to the cross frame 8, and the first screw rod 6 is threadedly connected to the cross frame 8. The first screw rod 6 is driven to rotate by a motor, which can drive the cross frame 8 and the spindle 12 to rise and fall.

[0049] Reference Figure 3 and Figure 4 , two movable grooves 9 are provided on the side of the horizontal frame 8 away from the U-shaped frame 5, and a second screw rod 10 is rotatably connected in each movable groove 9. Two movable seats 11 are respectively slidably sleeved on the outer wall of the horizontal frame 8 and are threadedly connected with the two second screw rods 10. The two second screw rods 10 are driven to rotate by a motor, which can respectively drive the two movable seats 11 to move on the horizontal frame 8, thereby realizing the lateral movement of the two main shafts 12. In this way, through the cooperation of the first screw rod 6 and the two second screw rods 10, the two main shafts 12 can be driven to move synchronously to the processing position to be processed, thereby improving the processing efficiency.

[0050] Reference Figure 1 and Fig. 9 The protective structure is used to automatically brake the moving door 31 during the processing. Specifically, a push rod 34 is slidably passed through one side of the protective cover 2, and the push rod 34 cooperates with the workbench 13. When the workbench 13 moves outward, it will push the push rod 34 to move outward. The outer wall of the push rod 34 is sleeved with a tension spring 35, one end of the tension spring 35 is fixedly connected to one side of the protective cover 2, and the other end is fixedly connected to the outer wall of the push rod 34. Under the action of the tension spring 35, when the workbench 13 moves inward or stops, the push rod 34 will automatically move inward.

[0051] Reference Figure 1 and Fig. 9 The top of the push rod 34 is rotatably connected to a connecting rod 37, and the top of the connecting rod 37 is rotatably connected to the bottom of the pin 36. Therefore, when the push rod 34 moves inward, the pin 36 is driven to rise through the connecting rod 37 and inserted into the pin hole 33 at the bottom of the movable door 31, thereby braking the movable door 31. In this way, even if there is an unexpected impact or vibration outside during the processing, the movable door 31 will not be accidentally opened, ensuring the safety of the processing process.

[0052] Reference Figure 5-Figure 8, the chip removal structure is arranged on the base 1, and is used to automatically discharge the iron chips generated during the processing into the chip removal port 3. Specifically, a long strip sliding groove 15 is designed and processed on the top of the base 1. A third screw rod 17 is installed in the sliding groove 15, and it is ensured that it can rotate freely. One end of the third screw rod 17 can be connected to the driving motor to provide rotational power later. A nut block 16 is installed in the sliding groove 15, which is threadedly connected to the third screw rod 17. The top of the nut block 16 is fixedly connected to the bottom of the workbench 13 by bolts or welding. In this way, when the third screw rod 17 rotates, it can drive the nut block 16 to move left and right in the sliding groove 15, thereby driving the workbench 13 to move horizontally. At the bottom of the workbench 13, two clearance grooves 18 corresponding to the sliding grooves 15 are opened. In each clearance groove 18, a sliding plate 19 is installed, and it is ensured that it can slide freely on the top of the base 1. At the same time, a plurality of fixing rods 20 are respectively fixed on the inner walls of the two clearance grooves 18 that are close to each other. One end of the fixing rod 20 is slidably extended into the corresponding sliding plate 19 to increase the stability of the movement of the sliding plate 19 .

[0053] Reference Figure 8 A spring 21 is sleeved on the outer wall of each fixing rod 20. One end of the spring 21 is fixedly connected to the sliding plate 19, and the other end is fixedly connected to the inner wall of one side of the corresponding clearance groove 18. In this way, when the workbench 13 moves, the spring 21 drives the sliding plate 19 to slide on the base 1, thereby shoveling the iron filings on the base 1 onto the sliding plate 19.

[0054] Reference Figure 5-Figure 7 The chip removal structure also includes an annular groove 22 on the top of the workbench 13. A circular ring 23 is installed in the circular groove 22, and it is ensured that it can rotate freely. The top of the circular ring 23 is fixedly connected to the bottom of the four-jaw chuck 14. In this way, when the four-jaw chuck 14 rotates, it will drive the circular ring 23 to rotate synchronously. A bevel gear ring 24 is fixed on the outer wall of the circular ring 23, and it is ensured that it is located in the annular groove 22. Two rotating shafts 25 are installed in the workbench 13, and one end of them extends into the annular groove 22. At the end of each rotating shaft 25, a bevel gear 26 is fixed respectively, and it is ensured that the bevel gear 26 is meshed with the bevel gear ring 24. At the ends of the two rotating shafts 25 that are away from each other, they extend to both sides of the workbench 13 respectively, and the first synchronous wheel 27 is fixed. Two second synchronous wheels 28 are installed on both sides of the workbench 13. The first synchronous wheel 27 and the two second synchronous wheels 28 on the same side are connected by a synchronous belt 29 to form a transmission chain. A plurality of rubber scraping strips 30 are fixed on the outer wall of the synchronous belt 29 to remove iron filings on the sliding plate 19 .

[0055] Reference Figure 3In the base 1, two chip discharge ports 3 are provided, and are respectively located on both sides of the workbench 13. The chip discharge ports 3 are designed to ensure that the iron chips can be discharged downward smoothly.

[0056] Reference Figure 3 , two collecting boxes 4 are placed below the base 1, and ensure that they are matched with the chip discharge port 3. In this way, the iron chips discharged from the chip discharge port 3 can directly fall into the collecting box 4, which is convenient for subsequent cleaning and processing.

[0057] Reference Figure 6 In order to effectively protect the synchronous belt 29, the second synchronous wheel 28 and the first synchronous wheel 27 on both sides of the workbench 13, two arc-shaped guard plates 45 are fixedly installed on both sides of the workbench 13. The two arc-shaped guard plates 45 are designed and installed above the first synchronous wheel 27 to ensure that they can completely cover and protect the synchronous belt 29, the second synchronous wheel 28 and the first synchronous wheel 27 below. The material of the arc-shaped guard plate 45 should be a strong and wear-resistant material, such as stainless steel or high-strength alloy, to prevent damage by chips or coolant during processing, thereby ensuring long-term stability and reliability. Through this design, we have successfully achieved effective protection of key transmission components, extended the service life of the equipment, and reduced downtime caused by accidental damage.

[0058] In order to prevent the iron chips generated during the processing from splashing onto the two sides of the U-shaped frame 5, we have taken the following improvement measures: On the inner wall of the U-shaped frame 5 on one side close to each other, we have fixedly installed two horizontal plates. These two horizontal plates are designed and installed above the chip discharge port 3 to form a barrier to effectively block the splashing of iron chips. The material of the horizontal plate should also be strong and impact-resistant to ensure that it can withstand the impact force generated during the processing without deformation or damage. Through this design, we have successfully reduced the pollution of iron chips to the U-shaped frame 5 and the surrounding environment, and improved the cleanliness and safety of the working environment.

[0059] Through the above-mentioned implementation mode, the present invention provides a double-column double-channel CNC vertical lathe with a compact structure, easy operation and high safety, which can ensure that the double-column double-channel CNC vertical lathe can automatically remove iron filings on the base during the processing, avoid the influence of iron filings accumulation on the moving accuracy of the worktable 13, and improve the processing efficiency.

[0060] Example 2: Reference Fig.10 and Fig.11, improved on the basis of Example 1: In order to realize convenient storage and rust-proof maintenance of the tool chuck, we fixedly installed a fixing frame 38 on one side of the base 1, and rotatably connected a placement plate 39 in the fixing frame 38. A driving shaft 42 is fixedly passed through the placement plate 39, and fixing plates 41 are fixed at both ends of the driving shaft 42, and one end of the two fixing plates 41 is fixedly connected to the lathe body. On the placement plate 39, we designed a plurality of conical placement holes 40 for placing the tool chuck. In addition, in order to perform rust-proof maintenance on the tool chuck, we fixedly installed a liquid storage tank 43 on the top of the fixing plate 41 located above, and the liquid storage tank 43 contains rust-proof oil. At the same time, at the bottom of the fixing plate 41, we fixedly installed a plurality of electromagnetic nozzles 44, and these electromagnetic nozzles 44 are connected to the liquid storage tank 43 through a hose.

[0061] In actual use, we first place the tool chuck on the conical placement hole 40, and then drive the placement plate 39 to rotate through the drive shaft 42, and rotate the tool chuck that needs maintenance to the bottom of the electromagnetic nozzle 44. At this time, by controlling the switch of the electromagnetic nozzle 44, the anti-rust oil in the liquid storage tank 43 is sprayed onto the tool chuck. Due to the special design of the conical placement hole 40, the excess anti-rust oil can flow downward along its inner wall, thereby achieving all-round maintenance of the tool chuck and the tool. This design not only improves the storage efficiency of the tool chuck, but also realizes effective anti-rust maintenance of the tool, extending the service life of the tool.

[0062] A method for using a double-column double-channel CNC vertical lathe comprises the following steps:

[0063] S1. The workpiece to be processed is clamped and fixed by the four-jaw chuck 14, and the two movable doors 31 are closed. The third screw rod 17 is driven to rotate by the motor. The third screw rod 17 drives the workbench 13 and the four-jaw chuck 14 to move to the bottom of the horizontal frame 8 through the nut block 16 for processing. When the workbench 13 moves inward, the push on the push rod 34 is released. The push rod 34 moves inward under the tension of the tension spring 35. The push rod 34 drives the pin 36 to move up through the connecting rod 37 and inserts it into the pin hole 33, completing the braking of the movable door 31, so as to prevent the movable door 31 from being opened during the processing, resulting in the splashing of iron filings and workpieces.

[0064] S2, the first screw rod 6 is driven to rotate by the motor, the first screw rod 6 drives the cross frame 8 and the main shaft 12 to rise and fall, and the two second screw rods 10 are driven by the motor, the two second screw rods 10 respectively drive the corresponding moving seats 11 to move, and the main shaft 12 and the tool under the main shaft 12 (the tool under the main shaft 12 is composed of a tool holder and a tool) can be moved to the position to be processed. The cooperation of the first screw rod 6 and the two second screw rods 10 can drive the two main shafts 12 to synchronously complete the processing of the workpiece, thereby improving the processing efficiency;

[0065] S3. When the spindle 12 processes the workpiece, iron chips splash and are discharged into the collection box 4 through the chip discharge port 3. When the iron chips splash onto the base 1, the four-jaw chuck 14 and the sliding plate 19, the motor drives the four-jaw chuck 14 to rotate quickly, and the four-jaw chuck 14 throws out the iron chips on it. In addition, the third screw 17 drives the workbench 13 to move left and right, and the workbench 13 drives the sliding plate 19 to move through the spring 21, so that the sliding plate 19 shovels the iron chips on the base 1 onto the sliding plate 19, and the workbench 13 The movement can accumulate the iron filings on the sliding plate 19 to one place. In addition, when the four-jaw chuck 14 rotates, the bevel gear ring 24 is driven to rotate. The bevel gear ring 24 drives the first synchronous wheel 27 to rotate through the bevel gear 26. The first synchronous wheel 27 and the second synchronous wheel 28 cooperate to drive the synchronous belt 29 to rotate. The cooperation of the synchronous belt 29 and the rubber scraper 30 can discharge the iron filings on the sliding plate 19 to the corresponding chip discharge port 3, automatically completing the removal of the iron filings, and preventing the iron filings from accumulating on the base 1 and affecting the accuracy of the movement of the workbench 13.

[0066] S4. When the replaced tool jacket and tool (the tool is installed at one end of the tool jacket) need to be stored and maintained, the tool jacket is placed on the conical placement hole 40, and then the placement plate 39 is driven to rotate by the drive shaft 42 to rotate the tool jacket to the bottom of the electromagnetic nozzle 44. The anti-rust oil in the liquid storage tank 43 is sprayed onto the tool jacket through the electromagnetic nozzle 44, and the excess anti-rust oil can flow downward along the inner wall of the conical placement hole 40, thereby enabling comprehensive maintenance of the tool jacket and the tool.

[0067] However, as is well known to those skilled in the art, the working principle and wiring method of the electromagnetic nozzle 44 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.
