Description

Technical Field

[0001] This utility model belongs to the field of milling machine technology, specifically relating to a milling machine with the function of preventing chips from interfering with cutting. Background Technology

[0002] In the field of metal processing, milling machines, as a core cutting device, are widely used for high-precision machining of complex parts. In traditional milling, the cutting tool rotates at high speed and interacts violently with the workpiece material, generating a large amount of high-temperature metal chips.

The machine includes a base, a platform at the top of the base, a top plate above the platform, and columns installed at the corners of the bottom of the top plate. This eliminates the safety hazards that exist when using the milling machine, improves the convenience of using the milling machine, and ensures the milling accuracy. However, if these chips are not discharged from the machining area in a timely and effective manner, it will cause a series of problems that seriously affect the machining quality and equipment stability. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a milling machine with the function of preventing chips from interfering with cutting, comprising a milling machine housing and a machining mechanism disposed inside the milling machine housing. A first armored hose is fixedly connected to one side of the machining mechanism. A dust suction pipe is slidably connected inside the first armored hose. A positioning plate is fixedly connected to the bottom end of the dust suction pipe. A corrugated pipe is sleeved on the surface of the dust suction pipe. Both ends of the corrugated pipe are fixedly connected to the positioning plate and the first armored hose, respectively. A dust suction end is fixedly connected to the surface of the dust suction pipe. A second armored hose is disposed on one side of the milling machine housing. The first armored hose is inserted inside the second armored hose and slidably connected to it. A dust collection box is disposed on one side of the milling machine housing. The end of the second armored hose away from the first armored hose is inserted inside the dust collection box. A vacuum pump is disposed on one side of the dust collection box. The suction end of the vacuum pump is inserted inside the dust collection box.

[0006] Preferably, the bottom surface of the positioning plate is fixedly connected to a limiting ball socket, and a first auxiliary ball is provided inside the limiting ball socket, the first auxiliary ball being rotatably connected to the limiting ball socket.

[0007] Preferably, a second positioning shell is fixedly connected to the right side of the milling machine housing by bolts. The second armored hose is located inside the second positioning shell. The end of the second armored hose away from the first armored hose passes through the surface of the second positioning shell and is slidably connected to the second armored hose. A first positioning shell is fixedly connected to the bottom surface of the second positioning shell. The second armored hose is inserted into the interior of the first positioning shell and then into the interior of the dust collection box.

[0008] Preferably, a first bend is fixedly connected to the side of the processing mechanism away from the first armored hose, an air outlet pipe is slidably connected inside the first bend, a positioning plate is fixedly connected to the bottom surface of the air outlet pipe, and a second auxiliary ball is rotatably connected to the bottom surface of the positioning plate through a limiting ball socket. An air outlet end is fixedly connected to the surface of the air outlet pipe. A fan is installed on the top surface of the milling machine housing, a connecting pipe is installed on the output shaft of the fan, a second telescopic pipe is fixedly connected to the end of the connecting pipe away from the fan, a first telescopic pipe is fixedly connected to the end of the first bend pipe near the second telescopic pipe, and the first telescopic pipe and the second telescopic pipe are interconnected through the second bend pipe.

[0009] Preferably, a third positioning shell is fixedly connected to the left side of the milling machine housing, the second telescopic tube and the second bent tube are both located inside the third positioning shell, the second bent tube is slidably connected to the third positioning shell, and an air outlet pipe is slidably connected to the surface of the machining mechanism, with the two ends of the air outlet pipe being fixedly connected to the second armored flexible hose and the second bent tube, respectively.

[0010] Preferably, a concentrator is fixedly connected to the end of the suction end that is adjacent to the air outlet end.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes a sliding nested structure of the suction pipe and the armored hose, along with a positioning shell guiding mechanism. The suction end can follow the movement trajectory of the processing mechanism in three-dimensional space in real time. Driven by a vacuum pump, cutting chips are directly sucked into the dust collection box, effectively preventing chip accumulation from interfering with the tool path or damaging the workpiece surface, thus significantly improving processing accuracy and surface quality.

[0013] 2. This utility model uses directional airflow from the air outlet to lift debris, forming a "dual flow field of blowing and suction" with the suction end. The concentrator design further focuses the airflow, enabling active migration and relay recycling of debris, thus solving the problem of insufficient removal of attached debris in traditional single suction mode.

[0014] 3. This utility model integrates a first auxiliary ball and a second auxiliary ball into a dust suction end and an air outlet end, respectively. The ball and the workpiece surface are made into rolling contact through the limiting ball socket. When the processing mechanism moves down, the auxiliary ball is squeezed by the workpiece and drives the dust suction pipe and the air outlet pipe to slide axially. When moving, the auxiliary ball rolls along the curved surface, so that the suction and blowing port always maintains a constant distance from the irregular contour, ensuring the high-efficiency dust removal adaptability of complex geometric workpieces such as curved surfaces and inclined surfaces.

[0022] 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.

[0023] Please see Figures 1-6This utility model provides a milling machine with a function to prevent debris from interfering with cutting. It includes a milling machine housing 1 and a machining mechanism 2 disposed inside the milling machine housing 1. A first armored hose 7 is fixedly connected to one side of the machining mechanism 2. A suction pipe 4 is slidably connected inside the first armored hose 7. A positioning plate is fixedly connected to the bottom end of the suction pipe 4. A corrugated tube is sleeved on the surface of the suction pipe 4, and both ends of the corrugated tube are fixedly connected to the positioning plate and the first armored hose 7, respectively. A suction end 6 is fixedly connected to the surface of the suction pipe 4. A second armored hose is provided on one side of the milling machine housing 1. A first armored hose 7 is inserted inside and slidably connected to a second armored hose 8. A dust collection box 9 is provided on one side of the milling machine housing 1. The end of the second armored hose 8 away from the first armored hose 7 is inserted into the dust collection box 9. A vacuum pump 10 is provided on one side of the dust collection box 9, and the suction end of the vacuum pump 10 is inserted into the dust collection box 9. A second positioning shell 20 is fixedly connected to the right side of the milling machine housing 1 by bolts. The second armored hose 8 is located inside the second positioning shell 20, and the end of the second armored hose 8 away from the first armored hose 7 passes through... The second positioning shell 20 is slidably connected to the second armored hose 8. The bottom surface of the second positioning shell 20 is fixedly connected to the first positioning shell 19. The second armored hose 8 is inserted into the interior of the first positioning shell 19 and then into the interior of the dust collection box 9. When the processing mechanism 2 is cutting the part, the vacuum pump 10 is connected to an external power source and started. The debris cut from the part enters the interior of the suction end 6, then enters the interior of the first armored hose 7 through the suction pipe 4, and then enters the interior of the dust collection box 9 through the second armored hose 8. This keeps the debris away from the processing area, thus preventing the debris from affecting the part processing. When the processing mechanism 2 moves up and down, the suction pipe 4 slides inside the first armored hose 7. When the processing mechanism 2 moves left and right, the first armored hose 7 moves inside the second armored hose 8. When the processing mechanism 2 moves back and forth, the second armored hose 8 slides inside the first positioning shell 19. This allows the mechanism to move with the processing mechanism 2, making it easy to collect debris.

[0024] In this embodiment, a limiting ball socket is fixedly connected to the bottom surface of the positioning plate, and a first auxiliary ball 5 is provided inside the limiting ball socket. The first auxiliary ball 5 is rotatably connected to the limiting ball socket. In order to facilitate the application of parts of different shapes, when the processing mechanism 2 moves downward, the first auxiliary ball 5 will come into contact with the part. The first auxiliary ball 5 will cause the suction pipe 4 to slide inside the first armored hose 7 due to the compression of the part. When the processing mechanism 2 moves, the first auxiliary ball 5 will roll on the surface of the part, thus realizing the application of parts of different shapes.

[0025] In this embodiment, a first bend 14 is fixedly connected to the side of the processing mechanism 2 away from the first armored flexible hose 7. An air outlet 11 is slidably connected inside the first bend 14. A positioning plate is fixedly connected to the bottom surface of the air outlet 11, and a second auxiliary ball 12 is rotatably connected to the bottom surface of the positioning plate through a limiting ball socket. An air outlet end 13 is fixedly connected to the surface of the air outlet 11. A fan 3 is installed on the top surface of the milling machine housing 1. A connecting pipe 18 is installed on the output shaft of the fan 3. A second auxiliary ball 12 is fixedly connected to the end of the connecting pipe 18 away from the fan 3. Telescopic tube 16, first bend tube 14 near one end of second telescopic tube 16 is fixedly connected to first telescopic tube 15, first telescopic tube 15 and second telescopic tube 16 are connected to each other through second bend tube 17, third positioning shell 21 is fixedly connected to the left side of milling machine housing 1, second telescopic tube 16 and second bend tube 17 are both located inside third positioning shell 21, second bend tube 17 is slidably connected to third positioning shell 21, air outlet tube 11 is slidably connected to the surface of machining mechanism 2, both ends of air outlet tube 11 are respectively connected to second armored soft Pipe 8 and the second curved pipe 17 are fixedly connected. To facilitate the quick and easy collection of debris, when the processing mechanism 2 is processing, the fan 3 is connected to an external power source and started. The air will enter the interior of the second telescopic pipe 16 through the connecting pipe 18, then enter the interior of the first telescopic pipe 15 through the second curved pipe 17, and then enter the interior of the air outlet pipe 11 through the first curved pipe 14. Finally, it will be discharged from the air outlet 13 and blown towards the processing position, which will lift up the debris. The lifted debris will be collected by the dust suction end 6, thus realizing the relay of debris and making it easier to quickly collect debris. The second auxiliary ball 12 can also fit with the part, thus adapting to parts of different shapes. When the processing mechanism 2 moves up and down, the air outlet pipe 11 will slide inside the first curved pipe 14. When the processing mechanism 2 moves left and right, the first telescopic pipe 15 will extend and retract. When the processing mechanism 2 moves back and forth, the air outlet pipe 11 will drive the second curved pipe 17 to move inside the second positioning shell 20, realizing the extension and retraction of the second telescopic pipe 16, thus realizing the change of movement with the processing mechanism 2.

[0026] In this embodiment, both the suction end 6 and the air outlet end 13 are fixedly connected to a concentrator. The two concentrators enhance the concentration of blowing and suction, respectively, making it easier to discharge materials.

[0027] The use of this utility model involves the following steps:

[0028] S1: When the processing mechanism 2 is cutting the part, the vacuum pump 10 is connected to an external power source and started. The chips cut from the part will enter the interior of the suction end 6, then enter the interior of the first armored hose 7 through the suction pipe 4, and then enter the interior of the dust collection box 9 through the second armored hose 8. This keeps the chips away from the processing area, thus preventing the chips from affecting the part processing. When the processing mechanism 2 moves up and down, the suction pipe 4 will slide inside the first armored hose 7. When the processing mechanism 2 moves left and right, the first armored hose 7 will move inside the second armored hose 8. When the processing mechanism 2 moves back and forth, the second armored hose 8 will slide inside the first positioning shell 19. This allows the mechanism to move with the processing mechanism 2, making it easy to collect the chips.

[0029] S2: In order to facilitate the application of parts of different shapes, when the processing mechanism 2 moves downward, the first auxiliary ball 5 will come into contact with the part. The first auxiliary ball 5 will cause the suction pipe 4 to slide inside the first armored hose 7 due to the pressure of the part. When the processing mechanism 2 moves, the first auxiliary ball 5 will roll on the surface of the part, thus realizing the application of parts of different shapes.

[0030] S3: To facilitate quick and easy debris removal, when the processing mechanism 2 is processing, the fan 3 is connected to an external power source and started. The air will enter the interior of the second telescopic tube 16 through the connecting pipe 18, then enter the interior of the first telescopic tube 15 through the second bend pipe 17, and then enter the interior of the air outlet 11 through the first bend pipe 14. Finally, it will be discharged from the air outlet 13 and blown towards the processing position, which will lift up the debris. The lifted debris will be sucked up by the dust suction end 6, thus realizing the relay of debris and making it easier to quickly remove debris. The second auxiliary ball 12 can also fit with the part, thus adapting to parts of different shapes. When the processing mechanism 2 moves up and down, the air outlet 11 will slide inside the first bend pipe 14. When the processing mechanism 2 moves left and right, the first telescopic tube 15 will extend and retract. When the processing mechanism 2 moves back and forth, the air outlet 11 will drive the second bend pipe 17 to move inside the second positioning shell 20, realizing the extension and retraction of the second telescopic tube 16, thus realizing the change of movement with the processing mechanism 2.

[0031] S4: The two air concentrators enhance the concentration of blowing and suction, making material discharge easier.
