Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a CNC machine tool waste collection mechanism. Background Technology

[0002] CNC machine tools are precision machines controlled by CNC programs to perform precision machining on corresponding parts. They integrate mechanical, automation, computer, and microelectronic technologies and are flexible and efficient automated machine tools. In the process of high-precision machining of metal parts, some metal waste will inevitably be generated. In order to avoid waste of resources, it is necessary to recycle and reuse this waste.

[0003] Currently, existing waste collection mechanisms still have certain shortcomings. In use, a collection box is usually placed under the workpiece that generates waste. However, the cutting waste generated by CNC machine tools during the cutting process moves with the cutting tool, making it difficult to ensure that it falls directly into the collection box. In addition, some waste is in the form of long strands, which are fluffy when they fall into the collection box, taking up a lot of storage space. Therefore, it is urgent to design a CNC machine tool waste collection mechanism to solve the above problems. Summary of the Invention

The end of the movable column is connected to the outer wall of the collection box. A telescopic member is fixedly disposed through the outer wall of the seat, and the telescopic end of the telescopic member is connected to the outer wall of the collection box.

[0011] As a further embodiment of the present invention: the limiting mechanism includes four telescopic members that are fixedly disposed through the four corners of the outer wall of the seat, and the telescopic end of the four telescopic members is provided with a movable plate. The outer wall of the movable plate is provided with a movable rod, and one end of the movable rod is provided with a baffle plate.

[0017] This invention provides a CNC machine tool waste collection mechanism. A collection box can be moved to below the machining position of the CNC machine tool via casters. A limiting mechanism then limits the position of the base, ensuring the stability of the collection box. Before machining the workpiece, the height of the collection box can be adjusted via a lifting mechanism, positioning the protective plates on both sides of the workpiece. A telescopic component then moves the movable frame, and the protective plates within the movable frame move together until their ends align. The aligned protective plates then shield the workpiece. The CNC machine tool... When cutting a workpiece, the scrap material splashed in all directions can be blocked by the protective plate and fall between the rotating rollers, making the scrap collection process safer. The rotating rollers can crush the loose cutting scrap material, which can effectively reduce the space occupied by the scrap material. The crushed scrap material can fall to the bottom of the collection box through the gaps between the fixed plates. Then, the scrap material at the bottom of the collection box can be squeezed by the extrusion mechanism to further reduce the space occupied by the scrap material. The scrap material is finally squeezed into blocks, which is not only easy to remove, but also convenient for subsequent processing and transportation, resulting in better performance.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, an embodiment of the present invention provides a CNC machine tool waste collection mechanism, including a base 1 and a collection box 7. Telescopic members 18 are fixedly and continuously installed on both outer walls of the collection box 7. The specific structure of the telescopic members 18 is not limited. In this embodiment, preferably, the telescopic members 18 are hydraulic cylinders, and the telescopic end of the telescopic members 18 is provided with a movable frame 17. A protective plate 14 is movably installed in the movable frame 17, and the cross-section of the protective plate 14 is inverted J-shaped. A stop bar 1 is also provided on the outer wall of the protective plate 14. 6. The outer wall of the collection box 7 is equipped with an electric motor, and the drive end of the electric motor is equipped with a rotating roller 12. The rotating roller 12 is located in the collection box 7, and the outer wall of the rotating roller 12 is equipped with crushing teeth 13. The collection box 7 is also equipped with a fixing plate 21, and the cross-section of the fixing plate 21 is L-shaped. The end of the fixing plate 21 is located below the rotating roller 12. A pick-up and drop-off port is also opened on one side of the outer wall of the collection box 7, and a box door is movably installed in the pick-up and drop-off port. The four corners of the bottom outer wall of the base 1 are equipped with moving wheels 4. It also includes:

[0025] Lifting mechanism 2 is located between the base 1 and the collection box 7 and is used to control the height of the collection box 7.

[0026] The extrusion mechanism 11 is disposed in the collection box 7 and is used to extrude waste material in the collection box 7.

[0027] Limiting mechanism 22 is disposed on the outer wall of the seat 1 and is used to limit the position of the seat 1.

[0028] The collection box 7 can be moved to below the machining position of the CNC machine tool using the movable wheels 4. The position of the base 1 can then be limited by the limiting mechanism 22, ensuring the stability of the collection box 7. Before machining the workpiece, the height of the collection box 7 can be adjusted using the lifting mechanism 2, so that the protective plates 14 are located on both sides of the workpiece. Then, the movable frame 17 can be moved by the telescopic component 18, and the protective plates 14 in the movable frame 17 can move together until the ends of the protective plates 14 are aligned. After alignment, the protective plates 14 can shield the workpiece. The CNC machine tool can then proceed with machining the workpiece... Waste material splashed in all directions during cutting can be blocked by the protective plate 14 and fall between the rotating rollers 12, making the waste collection process safer. The rotating rollers 12 can crush the loose cutting waste material, which can effectively reduce the space occupied by the waste material. The crushed waste material can fall to the bottom of the collection box 7 through the gap between the fixed plates 21. Then, the waste material at the bottom of the collection box 7 can be squeezed by the extrusion mechanism 11 to further reduce the space occupied by the waste material. The waste material is finally squeezed into a block shape, which is not only convenient to take out, but also convenient for subsequent processing and transportation, resulting in better performance.

[0029] As one embodiment of the present invention, please refer to Figure 1 The lifting mechanism 2 includes a fixed cylinder 5 disposed on the outer wall of the base 1, and a movable column 6 is movably disposed in the fixed cylinder 5. The end of the movable column 6 is connected to the outer wall of the collection box 7. A telescopic member 3 is fixedly disposed through the outer wall of the base 1. The specific structure of the telescopic member 3 is not limited. In this embodiment, preferably, the telescopic member 3 is a hydraulic cylinder, and the telescopic end of the telescopic member 3 is connected to the outer wall of the collection box 7. The collection box 7 can be lifted and lowered by the extension and retraction of the telescopic member 3. During the lifting and lowering of the collection box 7, the movable column 6 can move in the fixed cylinder 5, which effectively ensures the stability of the collection box 7 during lifting and lowering, and the use effect is better.

[0030] As one embodiment of the present invention, please refer to Figure 2 and Figure 4The limiting mechanism 22 includes telescopic members 23 that are fixedly installed at the four corners of the outer wall of the base 1. The specific structure of the telescopic members 23 is not limited. In this embodiment, preferably, the telescopic members 23 are hydraulic cylinders, and the telescopic end of the telescopic members 23 is provided with a movable plate 24. A movable rod 25 is provided through the outer wall of the movable plate 24, and a baffle 26 is provided at one end of the movable rod 25. A stop plate 28 is provided at the other end of the movable rod 25, and an elastic member 27 is sleeved on the outer wall of the movable rod 25. The specific structure of the elastic member 27 is not limited. In this embodiment, preferably… The elastic element 27 is a spring, and the outer wall of the abutment plate 28 is provided with an anti-slip pad 30. The other side of the outer wall of the abutment plate 28 is provided with a touch switch 29. When the seat 1 moves to a suitable position, the moving plate 24 can be moved down by the telescopic element 23, so that the anti-slip pad 30 on the outer wall of the abutment plate 28 contacts the ground, and the elastic element 27 on the outside of the movable rod 25 is compressed until the moving plate 24 contacts the touch switch 29, which triggers the telescopic element 23 to stop working, ensuring that the abutment plate 28 can apply a suitable supporting force to the ground, thereby ensuring the stability of the seat 1 and improving the performance.

[0031] As one embodiment of the present invention, please refer to Figure 3 The extrusion mechanism 11 includes a telescopic member 2 8 that is fixedly installed through the inner wall of one side of the collection box 7. The specific structure of the telescopic member 2 8 is not limited. In this embodiment, preferably, the telescopic member 2 8 is a hydraulic cylinder, and the telescopic end of the telescopic member 2 8 is provided with a movable plate 31. The outer wall of the movable plate 31 is provided with a mounting rod 34. One end of the mounting rod 34 is provided with a stop block 33, and the other end of the mounting rod 34 is provided with an extrusion cover 10. The outer wall of the mounting rod 34 is sleeved with an elastic member 2 35. The specific structure of the elastic member 2 35 is not limited. In this embodiment, preferably, the elastic member 2 35 is a spring. The inner wall of the extrusion cover 10 is provided with a pressure sensor 36. The telescopic member 2 8 can drive the movable plate 31 to move. The movable plate 31 drives the extrusion cover 10 to move through the mounting rod 34. When the extrusion cover 10 extrudes the waste, the elastic member 2 35 on the outside of the mounting rod 34 is compressed until the movable plate 31 contacts the pressure sensor 36. The pressure sensor 36 can monitor the extrusion pressure to prevent excessive extrusion pressure from damaging the equipment.

[0032] As one embodiment of the present invention, please refer to Figure 1 and Figure 3The outer wall of the movable plate 31 is equipped with a distance sensor 32, and the inner wall of the collection box 7 is equipped with a distance receiver 9 that cooperates with the distance sensor 32. The distance sensor 32 can emit infrared light, which can be received by the distance receiver 9 to monitor the movement position of the extrusion cover 10. When the pressure sensor 36 can detect the pressure value, the pressure value can reflect the extrusion force. The appropriate extrusion force is inversely proportional to the movement distance of the extrusion cover 10. Thus, the more waste in the collection box 7, the greater the extrusion force and the better the extrusion effect.

[0033] As an embodiment of the present invention, telescopic component 1 3, telescopic component 2 8, telescopic component 3 18 and telescopic component 4 23 are all connected to a controller via wires, and the distance receiver 9, pressure sensor 36 and touch switch 29 are electrically connected to the controller. The specific structure of the controller is not limited. In this embodiment, preferably, the controller is a microprogrammed controller.

[0034] As one embodiment of the present invention, please refer to Figure 1 The inner wall of the protective plate 14 is also provided with a guide plate 15, and one end of the protective plate 14 is provided with a moving block 19. The inner wall of the fixed plate 21 is provided with a fixed block 20, and the cross-section of the fixed block 20 and the moving block 19 are both semi-circular. When the protective plate 14 moves towards the middle, the moving block 19 at the end of the protective plate 14 will contact the fixed block 20 and cause the protective plate 14 to be lifted up, so that the guide plate 15 on the inner wall of the protective plate 14 can pass over the rotating roller 12 and the end of the guide plate 15 moves between the rotating rollers 12. Under the guiding action of the guide plate 15, the waste can enter the gap between the rotating rollers 12 better, and the use effect is better.

[0035] In use, the collection box 7 can be moved to below the machining position of the CNC machine tool using the movable wheels 4. Then, the position of the base 1 can be limited by the limiting mechanism 22 to ensure the stability of the collection box 7. Before the CNC machine tool processes the workpiece, the height of the collection box 7 can be adjusted by the lifting mechanism 2 so that the protective plate 14 is located on both sides of the workpiece. Then, the movable frame 17 can be moved by the telescopic component 18. The protective plate 14 in the movable frame 17 can move together until the ends of the protective plates 14 are aligned. After alignment, the protective plates 14 can shield the workpiece. When the CNC machine tool processes the workpiece... When the workpiece is being cut, the waste material splashed in all directions can be blocked by the protective plate 14 and fall between the rotating rollers 12, making the waste collection process safer. The rotating rollers 12 can crush the loose cutting waste material, which can effectively reduce the space occupied by the waste material. The crushed waste material can fall into the bottom of the collection box 7 through the gap between the fixed plates 21. Then, the waste material at the bottom of the collection box 7 can be squeezed by the extrusion mechanism 11 to further reduce the space occupied by the waste material. The waste material is finally squeezed into a block shape, which is not only convenient to remove, but also convenient for subsequent processing and transportation, resulting in better performance.

[0036] It should be noted that although this specification describes the embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
