Technical Field
[0001] This application relates to the technical field of CNC lathe machining, and in particular to an automatic chip cleaning device for CNC lathes. Background Technology
[0002] In the field of machining, CNC lathes, as core equipment for metal cutting, are widely used in the processing of shaft and disc parts (such as crankshafts, gears, and flanges) in industries such as automotive parts, construction machinery, and aerospace. During the machining process, a large amount of chips are generated depending on the material and process. These include sharp ribbon chips, fine granular chips, and viscous chips mixed with cutting fluid. The real-time cleaning of these chips directly affects machining accuracy, equipment lifespan, and production safety.
[0003] The industry has put forward three core technical requirements for chip removal devices: First, efficient real-time cleaning, which needs to be carried out simultaneously with lathe machining to avoid chip accumulation and prevent affecting tool path and workpiece surface quality; second, separation of chips and cutting fluid, with cutting fluid, as a lubricating and cooling medium, needing to be recycled and reused, while avoiding transportation pollution caused by chips carrying cutting fluid; and third, convenient operation and maintenance, which needs to achieve rapid collection and emptying of chips to meet the needs of mass production.
[0004] As my country's manufacturing industry transforms towards "precision and automation," the technical defects of traditional chip cleaning methods have become a key bottleneck restricting production efficiency and processing quality. This is especially true in small and medium-sized manufacturing enterprises and multi-variety production lines, where the increased costs and efficiency losses caused by untimely cleaning and incomplete separation are more prominent, necessitating targeted technical improvements.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses an automatic chip cleaning device for a CNC lathe. (Refer to...) Figure 1-4 An automatic chip cleaning device for CNC lathes, comprising a chip guiding mechanism and a collection mechanism;
[0024] The chip guiding mechanism is located below the lathe bed and is inclined. Its main body is a rectangular conveyor box 1. The conveyor box 1 is equipped with a spiral conveying rod 15. A fixed frame 3 is fixedly installed on one side of the conveyor box 1. One end of the spiral conveying rod 15 movably passes through the side wall of the conveyor box 1 and is rotatably connected to the fixed frame 3. A drive motor 4 is fixedly installed on the side of the fixed frame 3 away from the conveyor box 1. The output end of the drive motor 4 is fixedly connected to one end of the spiral conveying rod 15. A chip inlet 2 is fixedly connected to the upper surface of the conveyor box 1 along the length direction.
[0025] The collection mechanism is located below the end of the chip guiding mechanism and includes a collection box 6, a fixed frame 11, and a liquid collection box 14. The end of the conveying box 1 is fixedly connected to the collection box 6. The collection box 6 has a movable groove 17 and an installation groove 18 on the side away from the conveying box 1. The fixed frame 11 is slidably arranged in the movable groove 17. A filter screen 16 is fixedly installed on the bottom side inside the fixed frame 11. The liquid collection box 14 is slidably arranged in the installation groove 18. The collection box 6 is provided with a limiting component for limiting the fixed frame 11 and the liquid collection box 14. The limiting component includes a support plate 9, a connecting rod 10, and a limiting strip 13. The support plate 9 is fixedly connected to one side of the collection box 6. The connecting rod 10 is slidably installed through the side wall of the support plate 9. The bottom end of the connecting rod 10 is fixedly connected to the limiting strip 13. The side walls of the fixed frame 11 and the liquid collection box 14 are in contact with the limiting strip 13. The top end of the connecting rod 10 is fixedly connected to a handle 8.
[0026] A handle 12 is fixedly connected to one side of both the fixed frame 11 and the liquid collection box 14;
[0027] A support bar 19 is fixedly installed on one side inside the collection box 6 to support the fixed frame 11;
[0028] Two support legs 5 are fixedly installed on the lower surface of the conveyor box 1;
[0029] An observation window 7 is fixedly installed on one side of the collection box 6.
[0030] The implementation principle of the automatic chip cleaning device for CNC lathes in this application embodiment is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. During installation, the chip guide mechanism's conveyor box 1 is tilted and fixed below the lathe bed, ensuring that the chip inlet 2 is directly opposite the chip falling area of the lathe guide rail and turret. After the CNC lathe starts machining, the drive motor 4 is simultaneously turned on. The drive motor 4 drives the spiral conveyor rod 15 to rotate inside the conveyor box 1, and the rotating spiral blades generate propulsion. The chips generated during machining fall from the chip inlet 2 into the conveyor box 1 under gravity and are continuously pushed towards the end of the conveyor box 1 by the spiral blades. The tilted conveyor box 1, combined with the propulsion action of the spiral conveyor rod 15, prevents chips from accumulating and clogging inside the box. Even highly adhesive aluminum alloy chips can move smoothly under the combined action of the spiral thrust and the tilted gravity, resulting in stable conveying efficiency. The support legs 5 below the conveyor box 1 provide support, preventing positional shifts due to vibration during conveying. After the chips enter the collection box 6 via the screw conveyor 15, they first fall onto the filter screen 16 inside the fixed frame 11. The filter screen 16 is a metal mesh with a pore size of 1-2 mm, which can block the chips from passing through while allowing the mixed cutting fluid to penetrate. After passing through the filter screen 16, the cutting fluid flows along the inner wall of the collection box 6 into the collection box 14 below, realizing the physical separation of chips and cutting fluid. The separated chips remain on the filter screen 16, gradually accumulating into lumps or loose pieces, which facilitates subsequent centralized processing. The support bars 19 inside the collection box 6 support the fixed frame 11, preventing the fixed frame 11 from deforming or sinking due to excessive chip weight, ensuring that the filter screen 16 always remains horizontal and the separation efficiency is stable. The recoverable cutting fluid in the collection box 14 can be directly reintroduced into the lathe cooling system for recycling, reducing resource waste. The observation window 7 on one side of the collection box 6 is made of transparent acrylic material, allowing operators to observe the amount of chips accumulated on the filter screen 16 and the cutting fluid level in the collection box 14 in real time, preventing chip overflow or cutting fluid spillage. During operation, the limiting components lock the fixed frame 11 and the collection box 14: the support plate 9 is fixed to the side wall of the collection box 6, and the connecting rod 10 passes through the support plate 9 and connects to the limiting strip 13. The limiting strip 13 fits against the outer side wall of the fixed frame 11 and the collection box 14, and remains pressed down under gravity to prevent the fixed frame 11 and the collection box 14 from sliding due to equipment vibration or chip impact. When the observation window 7 shows that the chips are full or the cutting fluid is about to overflow, the operator holds the handle 8 and pulls the connecting rod 10 upwards, causing the limiting strip 13 to disengage from the fixed frame 11 and the collection box 14. After the limiting is released, the fixed frame 11 and the collection box 14 can be pulled out from the movable slot 17 and the mounting slot 18 through the handle 12. After the fixed frame 11 is pulled out, the internal chips can be poured out directly, and after the collection box 14 is pulled out, the recovered cutting fluid can be poured into the lathe cooling system. After cleaning, the fixed frame 11 and the collection box 14 are pushed back into their corresponding slots, the handle 8 is released, and the limiting strip 13 resets under gravity, relocking their positions.
[0031] During this process, the chip guiding mechanism operates synchronously with the lathe machining, and real-time automatic cleaning improves the continuity of machining. The combination of filter screen 16 and liquid collection box 14 achieves the separation of chips and cutting fluid, reducing production costs. The lifting design of the limiting component and the handle 12 structure make it possible to install and remove the fixed frame 11 and liquid collection box 14 without tools, which facilitates maintenance and operation, reduces labor intensity, and the overall structure is relatively simple and easy to use, thus improving the practicality of the device.
