[0002] In the modern manufacturing industry, CNC machine tools have become the core equipment in the parts processing process due to their significant advantages of high precision, high efficiency and high automation. However, CNC machine tools generate a large amount of chips, oil and dust during the processing. In order to ensure their normal operation, cleaning equipment is needed to clean these debris internally.

[0003] In the existing technology, some CNC machine tools use chain-type chip conveyors as cleaning equipment. These devices use chains to drive scrapers to transport chips, which can discharge chips from inside the CNC machine tool, thereby ensuring the stable operation of the equipment.

[0004] However, most chain-plate chip conveyors, in actual use, transport chips through chain plates and discharge them into the collection box. Their discharge ports are mostly fixed designs. This causes the chips to concentrate in the same position in the middle of the collection box during the chip removal process, easily forming an accumulation in the collection box and failing to spread evenly. As a result, when the chips are about to overflow, some space in the collection box is still not fully utilized, greatly reducing the practicality of the equipment. Therefore, a cleaning device for CNC machine tools is proposed to address the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figures 1-6This utility model provides a cleaning device for CNC machine tools, including a support shell 1; a conveyor chain plate 2 is provided in the middle of the support shell 1, a discharge shell 3 is fixedly connected to the bottom side of the end of the support shell 1, a fixing block 37 is fixedly connected to the bottom of the discharge shell 3, a guide shell 31 is rotatably connected to the side wall of the fixing block 37, a slide plate 34 is slidably connected to the middle of the guide shell 31, a fixing block 38 is rotatably connected to the bottom side wall of the slide plate 34, a rectangular frame 32 is fixedly connected to the bottom of the fixing block 38, a connecting frame 33 is fixedly connected to the side wall of the rectangular frame 32, and the connecting frame 33 is slidably connected to the outer wall of the end of the support shell 1. A support frame 4 is fixedly connected to the side wall of the support shell 1. A servo motor 41 is fixedly connected to the inner wall of the end of the support frame 4. A rotating plate 42 is mounted on the top of the servo motor 41 and is driven by the servo motor 41. A sliding column 45 is provided at the eccentric part of the bottom of the rotating plate 42. The outer wall of the bottom of the sliding column 45 slides in the middle of the connecting frame 33. During operation, the support shell 1 is installed inside the CNC machine tool, and the discharge shell 3 is placed outside the CNC machine tool. A collection box is set on the bottom side of the discharge shell 3. In this way, when using the CNC machine tool, the conveyor chain plate 2 can be started to move the CNC machine tool. The chips are cleaned out. The specific installation method and the operation method of the conveyor chain plate 2 are existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. During material discharge, the servo motor 41 can also be started to control the rotating plate 42 to rotate. At this time, the sliding column 45 will be at the eccentric position of the rotating plate 42 and rotate around the center of the rotating plate 42. At the same time, the other end of the sliding column 45 will slide in the middle of the connecting frame 33 and drive the connecting frame 33 to slide back and forth on the outer wall of the end of the support shell 1. The connecting frame 33 will drive the rectangular frame 32 to move back and forth. When the rectangular frame 32 moves, it will drive the second fixed block 38 to move as well. The second fixed block 38 will rotate with the slide plate 34, and the angle between the slide plate 34 and the guide shell 31 will change. The guide shell 31 will rotate with the first fixed block 37. The connection distance between the guide shell 31 and the slide plate 34 will also expand and contract as the rectangular frame 32 moves. In this way, the discharged chips will come into contact with the guide shell 31, pass through the rectangular frame 32 along its slope, and fall into the inside of the collection box. Moving the rectangular frame 32 will make the chips evenly spread inside the collection box, ensuring the utilization rate of the inside of the collection box and improving its practicality.

[0028] Furthermore, such as Figures 2-3 and Figures 5-6As shown, the side wall of the discharge shell 3 has a sliding groove 36, and a sliding shell 35 is slidably connected to the middle of the sliding groove 36. A movable shell 353 is slidably connected to the middle of the sliding shell 35. A scraper 352 is inserted into the middle of the movable shell 353. The top of the scraper 352 contacts the side wall of the conveyor chain plate 2, and a rubber strip 356 is fixed to the bottom side wall of the scraper 352. A limiting groove 355 is formed in the middle of the movable shell 353, and the rubber strip 356 contacts the middle of the limiting groove 355. A bolt 351 is threaded through the side wall of the sliding shell 35. A threaded hole 39 is provided on one side of the chute 36. The end of the bolt 351 is threaded into the middle of the threaded hole 39. During operation, when the conveyor chain plate 2 is conveying and discharging chips, the scraper 352 will contact the surface of the conveyor chain plate 2 and clean the chips adsorbed on the surface of the conveyor chain plate 2. When the scraper 352 needs to be disassembled for maintenance after a period of use, the bolt 351 can be rotated to disengage it from the middle of the threaded hole 39. Then, the sliding shell 35 can be pulled, which will drive the limiting groove 355 and the scraper 352 to move synchronously. As the scraper 352 moves, the inner wall of the support shell 1 pushes it along the inclined surface at the end of the scraper 352 towards the center of the sliding shell 35. The scraper 352 then moves the limiting groove 355 towards the center of the sliding shell 35. When the limiting groove 355 moves, it compresses the spring 354 until the scraper 352 is completely moved out of the inner side of the support shell 1. At this point, the spring 354 will push the sliding shell 353 and the scraper 352 back to their original positions through its elasticity, causing the scraper 352 to move out of the center of the sliding shell 35. Then, by directly pulling the scraper 352, it can be disassembled. When the scraper 352 is removed, it will move the rubber strip 356. The rubber strip 356 will deform due to its elasticity and move out from the middle of the limiting groove 355. During installation, simply insert the scraper 352 into the middle of the scraper 352. When inserting, the rubber strip 356 moves in the same way as above until it coincides with the limiting groove 355. It will then reset due to its elasticity and be inserted into the middle of the limiting groove 355. Then, push the sliding shell 35 completely into the middle of the sliding groove 36. Finally, fix the sliding shell 35 with bolts 351.

[0029] Furthermore, such as Figure 4As shown, the bottom of the rotating plate 42 is provided with a second sliding groove 46, and a slider 43 is slidably connected to the middle of the second sliding groove 46. The top of the sliding column 45 is rotatably connected to the bottom of the slider 43. A threaded rod 44 is rotatably connected through the outer wall of the rotating plate 42. The outer wall of the threaded rod 44 is threadedly connected to the middle of the slider 43. During operation, the reciprocating distance of the rectangular frame 32 can be adjusted according to the size of the collection box opening. Simply rotate the threaded rod 44, and the slider 43, which is threadedly connected to the outer wall of the threaded rod 44, will slide in the middle of the second sliding groove 46. The slider 43 will drive the sliding column 45 to move, so the distance between the sliding column 45 and the center of the rotating plate 42 will change. When the rotating plate 42 rotates, the reciprocating distance of the connecting frame 33 will also change accordingly, improving practicality.

[0030] Furthermore, such as Figures 5-6 As shown, the scraper 352 has beveled sides and ends. During operation, the beveled surfaces ensure that the scraper 352 can smoothly clean the surface of the conveyor chain plate 2. Furthermore, during disassembly, it can be smoothly moved out from the middle of the support shell 1, improving its practicality.

[0031] Furthermore, such as Figures 1-2 As shown, multiple sets of guide shells 31 and slide plates 34 are provided, and the multiple sets of guide shells 31 and slide plates 34 are symmetrically arranged with the center line of the rectangular frame 32 as the axis of symmetry. During operation, the multiple sets of guide shells 31 and slide plates 34 ensure that the chips are guided while reducing the risk of them splashing out.

[0032] Furthermore, such as Figure 6 As shown, the sidewall of the rubber strip 356 is set with an arc-shaped surface. During operation, the arc-shaped surface ensures that the rubber strip 356 can be smoothly inserted into the middle of the movable shell 353, thus improving practicality.

[0033] Furthermore, such as Figure 3 As shown, a spring 354 is fixedly connected to the bottom of the movable housing 353. The bottom of the spring 354 is fixedly connected to the middle of the sliding housing 35. During operation, the spring 354 ensures that the scraper 352 is in close contact with the surface of the conveyor chain plate 2, thus ensuring the cleaning effect and improving practicality.

[0034] Working principle: During material discharge, the servo motor 41 can be activated to control the rotating plate 42 to rotate. At this time, the sliding column 45 will rotate around the center of the rotating plate 42 at the eccentric position of the rotating plate 42. At the same time, the other end of the sliding column 45 will slide in the middle of the connecting frame 33 and drive the connecting frame 33 to slide back and forth on the outer wall of the end of the support shell 1. The connecting frame 33 will drive the rectangular frame 32 to move back and forth. When the rectangular frame 32 moves, it will drive the second fixed block 38 to move. The second fixed block 38 will rotate with the slide plate 34 and cause the angle between the slide plate 34 and the guide shell 31 to change. The guide shell 31 will rotate with the first fixed block 37. The connection distance between the guide shell 31 and the slide plate 34 will also expand and contract with the movement of the rectangular frame 32. In this way, the discharged chips will contact the guide shell 31 and pass through the rectangular frame 32 along its slope and fall into the inside of the collection box. Moving the rectangular frame 32 will make the chips evenly spread inside the collection box, ensuring the utilization rate of the inside of the collection box and improving its practicality.

[0035] When conveying and discharging chips, the scraper 352 contacts the surface of the conveyor chain 2 and cleans the chips adsorbed on the surface of the conveyor chain 2. When the scraper 352 needs to be disassembled for maintenance after a period of use, the bolt 351 can be turned to disengage it from the center of the threaded hole 39. Then, the sliding shell 35 can be pulled, which will drive the limiting groove 355 to move synchronously with the scraper 352. During the movement of the scraper 352, the inner wall of the support shell 1 will push it along the inclined surface at the end of the scraper 352 towards the center of the sliding shell 35. The scraper 352 will drive the limiting groove 355 towards the center of the sliding shell 35. When the limiting groove 355 moves, it will compress the spring 354 until the scraper 352 is completely moved from the inner side of the support shell 1. When the scraper 352 moves out, the spring 354 will push the moving shell 353 and the scraper 352 back to their original positions through its own elasticity, so that the scraper 352 moves out from the middle of the sliding shell 35. At this time, the scraper 352 can be removed by simply pulling it. When the scraper 352 moves, it will drive the rubber strip 356 to move. The rubber strip 356 will deform through its own elasticity and move out from the middle of the limiting groove 355. When installing, simply insert the scraper 352 into the middle of the sliding groove 355. When inserting, the movement of the rubber strip 356 is the same as above, until it coincides with the limiting groove 355. It will reset through its own elasticity and be inserted into the middle of the limiting groove 355. Then, push the sliding shell 35 completely into the middle of the sliding groove 36. Finally, fix the sliding shell 35 with the bolt 351.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
