[0004] The above patent increases the convenience of tool replacement, but debris will be generated during the machine tool processing, and the presence of debris will affect the processing accuracy of parts. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a CNC machining machine tool that facilitates chip removal to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a CNC machining machine tool that is convenient for chip removal, comprising a storage box, the outer wall of which is fixedly connected to a CNC machining component, the outer wall of which is clamped with a door panel, and the outer wall of which is fixedly connected to an impact mechanism. By setting the impact mechanism, the airflow blown by the fan can make the chips generated during the machining process fall into the storage box, effectively solving the problem of chip accumulation affecting the machining accuracy of parts during machine tool machining, ensuring the cleanliness of the machining area, and providing a good environment for high-precision machining;

[0007] The impact mechanism comprises:

[0008] A fan, wherein the fan is fixedly connected to the outer wall of the CNC machined component;

[0009] A pipeline, wherein the pipeline is fixedly connected to the outer wall of the fan;

[0010] A guide assembly is fixedly connected at the bottom of the pipeline.

[0011] Preferably, the CNC machining component includes a first moving device, which is movably connected to the top of the storage box, and the top of the first moving device is movably connected to a workbench. Each moving device in the CNC machining component can change the position of the machining device and the workbench under program control, so that the impact mechanism can move with the machining device, and realize efficient chip removal while processing the workpiece at different positions, thereby greatly improving the machining efficiency and chip removal effect, and avoiding the reduction of machining accuracy due to residual debris.

[0012] Preferably, the top of the storage box is movably connected to a second moving device, and the outer wall of the second moving device is movably connected to a mounting plate.

[0013] Preferably, the outer wall of the mounting plate is movably connected to a third movable component, and the outer wall of the third movable component is movably connected to a processing device.

[0014] Preferably, the fan is fixedly connected to the top of the processing device via a bracket.

[0015] Preferably, the guide assembly includes a bearing, the bearing is fixedly connected to the bottom of the pipe, the outer wall of the bearing is rotatably connected to a first guide plate, a torsion spring is rotatably connected between the first guide plate and the bearing, the outer wall of the bearing is fixedly connected to a second guide plate, the second guide plate and the first guide plate are staggered, so the airflow blown out of the pipe is guided, and then the airflow is guided toward the two sides of the workbench, the flow of the airflow guides the debris to fall into the storage box, the setting of the torsion spring allows the first guide plate to move, and the first guide plate is driven to move under the impact of the airflow, thereby guiding the airflow in more directions.

[0016] Preferably, the inner wall of the storage box is fixedly connected with a magnetic suction mechanism. The setting of the magnetic suction mechanism further optimizes the debris cleaning effect. The coil generates magnetism after power is turned on and is transmitted to the processing device through the fixed plate. It can absorb the debris and make it fall off the workpiece, effectively reducing the adverse effects of debris adhering to the workpiece on the processing accuracy, thereby improving the quality and accuracy of parts processing.

[0017] Preferably, the magnetic attraction mechanism includes an electric component, the electric component is fixedly connected to the inner wall of the storage box, the outer wall of the electric component is fixedly connected to a coil, the top of the coil is fixedly connected to a fixing plate, and the inner bottom of the storage box is fixedly connected to an auxiliary component.

[0018] Preferably, the fixed plate is fixedly connected to the bottom of the workbench, and the energized component is fixedly connected to the two ends of the coil by two energized wires. The telescopic machine in the auxiliary component can adjust the coil wire pitch. When it is necessary to clean the debris on the processing device, the magnetism of the processing device is weakened by reducing the coil wire pitch. At this time, the airflow blown out by the impact mechanism can more thoroughly clean the debris on the processing device and make it fall into the storage box. At the same time, the heat generated by the coil being energized can evaporate the moisture on the debris, reducing the adhesion of the debris due to moisture, reducing the potential threat of the debris to the processing accuracy, and ensuring the stability and reliability of the machine tool processing. According to Ampere's loop theorem, the magnetic field strength generated by the energized coil is related to factors such as the current in the coil, the number of coil turns, and the geometric shape of the coil. When the coil wire pitch is reduced, more turns can be wound in the same space. When the current remains unchanged, the increase in the number of turns will make the magnetic field superposition effect inside the coil more obvious, thereby increasing the intensity of the generated magnetic field and enhancing the magnetism.

[0019] Preferably, the auxiliary component includes a telescopic machine, which is fixedly connected to the inner bottom of the storage box, and the top of the telescopic machine is movably connected to a connecting block, the outer wall of the connecting block is fixedly connected to the bottom of the coil, and the top of the connecting block is fixedly connected to a limiting rod.

[0021] 1. This CNC machining tool that is easy to remove chips has an impact mechanism. The airflow blown by the fan can make the chips generated during the machining process fall into the storage box, effectively solving the problem of chip accumulation affecting the machining accuracy of parts during machine tool machining, ensuring the cleanliness of the machining area and providing a good environment for high-precision machining.

[0022] 2.

[0023] 3. This CNC machining tool that is easy to remove chips further optimizes the chip cleaning effect through the setting of the magnetic suction mechanism. The coil generates magnetism after being energized, which is transmitted to the processing device through the fixed plate, and can absorb the chips and make them fall off the workpiece, effectively reducing the adverse effects of chips adhering to the workpiece on the processing accuracy, and improving the quality and accuracy of part processing.

[0024] 4. The CNC machining center that facilitates chip removal can adjust the coil pitch through the telescopic machine in the auxiliary component. When it is necessary to clean the debris on the processing device, the magnetism of the processing device is weakened by reducing the coil pitch. At this time, the airflow blown out by the impact mechanism can more thoroughly clean the debris on the processing device and make it fall into the storage box. At the same time, the heat generated by the coil being energized can evaporate the moisture on the debris, reducing the adhesion of the debris due to moisture, reducing the potential threat of the debris to the processing accuracy, and ensuring the stability and reliability of the machine tool processing.

DETAILED DESCRIPTION

[0034] 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.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] For example, see Figure 1-4 The present invention provides a technical solution: a CNC machining machine tool that facilitates chip removal, comprising a storage box 1, a CNC machining component 3 is fixedly connected to the outer wall of the storage box 1, a door panel 2 is clamped to the outer wall of the storage box 1, and an impact mechanism 4 is fixedly connected to the outer wall of the CNC machining component 3;

[0037] The impact mechanism 4 comprises:

[0038] A fan 41, the fan 41 is fixedly connected to the outer wall of the CNC machining component 3;

[0039] A pipe 43, the pipe 43 is fixedly connected to the outer wall of the fan 41;

[0040] A guide assembly 44, the guide assembly 44 is fixedly connected to the bottom of the pipe 43;

[0041] The impact mechanism 4 is arranged on the processing device 36, so it can follow the movement of the processing device 36. Then, when the processing device 36 processes the parts, the fan 41 is powered on and started, and an air flow is blown out through the connection of the pipeline 43. When the air flow blows onto the workpiece, the generated debris will fall into the storage box 1.

[0042] The numerical control machining component 3 comprises a first moving device 31 , which is movably connected to the top of the storage box 1 , and a workbench 32 is movably connected to the top of the first moving device 31 .

[0043] The top of the storage box 1 is movably connected to a second moving device 33 , and the outer wall of the second moving device 33 is movably connected to a mounting plate 34 .

[0044] The outer wall of the mounting plate 34 is movably connected to a third moving component 35 , and the outer wall of the third moving component 35 is movably connected to a processing device 36 .

[0045] The fan 41 is fixedly connected to the top of the processing device 36 through a bracket 42;

[0046] Powering on the second moving device 33 and the third moving component 35 will change the position of the processing device 36. The activation of the second moving device 33 will change the y-position of the processing device 36. The movement of the third moving component 35 changes the z-position of the processing device 36. The activation of the first moving device 31 changes the x-position of the workbench 32, so the workpiece can be processed at different positions under the set program.

[0047] The guide assembly 44 includes a bearing 442, which is fixedly connected to the bottom of the pipe 43, a first guide plate 441 is rotatably connected to the outer wall of the bearing 442, a torsion spring 443 is rotatably connected between the first guide plate 441 and the bearing 442, and a second guide plate 444 is fixedly connected to the outer wall of the bearing 442;

[0048] The second guide plate 444 and the first guide plate 441 are staggered, so the airflow blown out of the pipe 43 is guided, and then the airflow is guided toward the two sides of the workbench 32. The flow of the airflow guides the debris to fall into the storage box 1. The setting of the torsion spring 443 allows the first guide plate 441 to move, and the first guide plate 441 is driven to move under the impact of the airflow, thereby guiding the airflow toward more directions.

[0049] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0050] The inner wall of the storage box 1 is fixedly connected with a magnetic attraction mechanism 5 .

[0051] The magnetic attraction mechanism 5 includes an electric component 51, which is fixedly connected to the inner wall of the storage box 1, a coil 53 is fixedly connected to the outer wall of the electric component 51, a fixing plate 54 is fixedly connected to the top of the coil 53, and an auxiliary component 55 is fixedly connected to the inner bottom of the storage box 1.

[0052] The fixing plate 54 is fixedly connected to the bottom of the workbench 32, and the current-carrying component 51 is fixedly connected to the two ends of the coil 53 through two current-carrying wires 52;

[0053] The coil 53 is connected to the bottom of the processing device 36 through the fixed plate 54, and the energized component 51 is connected to the coil 53 through the energized wire 52, so that the coil 53 generates magnetism. From a microscopic perspective, the current in the energized coil 53 is formed by the directional movement of free electrons. These moving electrons will generate a magnetic field. When a large number of electrons move in a directional manner in the wire, the magnetic fields generated by each of them are superimposed and act on each other, forming a magnetic field around the coil 53. After the coil 53 is energized, due to the existence of current and electromagnetic induction, a magnetic field is generated around the coil 53, thereby exhibiting magnetism. The magnetism is transmitted to the processing device 36 through the fixed plate 54, so that the processing device 36 absorbs the magnetism, so that the debris is absorbed from the workpiece.

[0054] The auxiliary component 55 includes a telescopic machine 551, which is fixedly connected to the inner bottom of the storage box 1, and the top of the telescopic machine 551 is movably connected to a connecting block 552, the outer wall of the connecting block 552 is fixedly connected to the bottom of the coil 53, and the top of the connecting block 552 is fixedly connected to a limiting rod 553;

[0055] According to Ampere's loop theorem, the magnetic field strength generated by the energized coil 53 is related to factors such as the current in the coil 53, the number of turns of the coil 53, and the geometric shape of the coil 53. When the line spacing of the coil 53 is reduced, more turns can be wound in the same space. Under the condition of constant current, the increase in the number of turns will make the magnetic field superposition effect inside the coil 53 more obvious, thereby increasing the intensity of the generated magnetic field and enhancing the magnetism.

[0056] The telescopic machine 551 is powered on and started, and the bottom of the coil 53 is driven to rise through the connecting block 552. At this time, the line spacing of the coil 53 is reduced, thereby reducing the magnetism of the processing device 36. When the magnetism is weakened, the airflow blown out of the pipe 43 will clean the debris on the processing device 36, and then the debris will fall into the storage box 1;

[0057] When the coil 53 is energized, heat is generated when current passes through the coil 53 due to the certain resistance of the coil 53 itself. The heat is then transferred to the debris on the processing device 36, thereby evaporating the moisture on the debris and reducing the adhesion of the debris due to moisture.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
