[0063] In the following description, a number of specific details are provided to provide a more thorough understanding of the technical solutions provided by the present invention. However, it is obvious to those skilled in the art that the technical solutions provided by the present invention can be implemented without one or more of these details.

[0064] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0065] Exemplary embodiments of the present invention will now be described in greater detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0066] like Figure 8 As shown, according to the first aspect of the embodiment of the present application, a method for evaluating the dust removal efficiency of a machine tool is proposed, comprising:

[0067] Step 101: Determine a follow-up dust removal detection point, an environmental dust removal detection point, and an operator position detection point on a machine tool;

[0068] Step 102: Controlling the machine tool to process the composite material, during which the follow-up dust removal system and the environmental dust removal system are turned off. After the system has been operated for a first period of time, first dust concentration values ​​at the follow-up dust removal detection point, the environmental dust removal detection point, and the operator position detection point are respectively obtained;

[0069] Step 103: Start the follow-up dust removal system and the environmental dust removal system. After the machine tool runs for a second period of time, obtain second dust concentration values ​​at the follow-up dust removal detection point, the environmental dust removal detection point, and the operator position detection point, respectively.

[0070] Step 104: Determine the dust removal efficiency of the machine tool based on the second dust concentration value.

[0071] The method for evaluating the dust removal efficiency of a machine tool provided in the embodiment of the present application can first control the machine tool to operate for a first period of time with the follow-up dust removal system and the environmental dust removal system turned off, and then turn on the follow-up dust removal system and the environmental dust removal system to operate for a second period of time, and then respectively obtain the second dust concentration values ​​of the follow-up dust removal detection point, the environmental dust removal detection point, and the operator position detection point, and finally determine the dust removal efficiency of the machine tool based on the second dust concentration value. This method can make the determination of the dust removal efficiency of the machine tool more accurate, and then optimize the follow-up dust removal system and the environmental dust removal system based on the dust removal efficiency of the machine tool, thereby improving the overall dust removal efficiency of the machine tool, reducing the amount of dust generated during the processing, especially reducing the amount of dust generated when the machine tool processes composite materials, improving the cutting accuracy of the machine tool, reducing pollution to the processing environment, and reducing the safety risks of flammable and explosive materials.

[0072] In some examples, three measuring points can be set in the machining area of ​​the machine tool, which are respectively at the first distance, the second distance and the third distance from the cutting point, with the first distance to the third distance increasing. The measuring point at the first distance is the follow-up dust removal detection point for detecting the follow-up dust removal efficiency, the measuring point at the second distance is the environmental dust removal detection point for detecting the environmental dust removal efficiency, and the measuring point at the third distance is the operator position detection point for detecting the dust concentration at the operator position to determine whether it causes harm to human health. It can be understood that the first dust concentration value and the second dust concentration value can both be three detection results, corresponding to the follow-up dust removal detection point, the environmental dust removal detection point and the operator position detection point, respectively. Based on this, the three dust removal efficiencies of the machine tool can be obtained from the three dimensions of follow-up, environment and operator, and then the follow-up dust removal system and the environmental dust removal system of the machine tool can be adjusted according to the three dust removal efficiencies, which can further improve the dust collection efficiency of the machine tool.

[0073] In some examples, the value of the first distance can be less than or equal to 0.5m, preferably 0.5m, the value of the second distance can be greater than 0.5m and less than or equal to 1.5m, preferably 1.5m, and the value of the third distance can be greater than 1.5m and less than or equal to 2.5m, preferably 2.5m.

[0074] In some examples, the step of controlling the machine tool to process the composite material may include: controlling the machine tool to work under different working parameters, and determining the first dust concentration value and the second dust concentration value under different processing parameters by constructing a table, which can make the determination of the dust removal efficiency of the machine tool more accurate.

[0075] In some examples, the different operating parameters may include, but are not limited to, spindle speed S, feed rate F, cutting width AP, cutting depth AE, and tool diameter D.

[0076] In some examples, the following table can be used to store data during the machine tool operation process, increase the data dimension, and improve the reliability of the dust removal efficiency determination.

[0077] Table 1. Data storage table of evaluation method for machine tool dust removal efficiency

[0078]

[0079] In some examples, the first duration may be 3 to 6 minutes, preferably 5 minutes, and the second duration may be 2 to 5 minutes, preferably 3 minutes.

[0080] In one feasible embodiment, the step of determining the dust removal efficiency of the machine tool based on the second dust concentration value includes: determining a theoretical dust removal weight based on the second dust concentration value; and determining the dust removal efficiency of the machine tool based on the theoretical dust removal weight and the mass consumption of the processed material. This configuration can make the dust removal efficiency of the machine tool more accurate and facilitate the calculation of the dust removal efficiency.

[0081] In a feasible implementation, the step of determining the dust removal efficiency of the machine tool based on the second dust concentration value includes: determining the dust removal efficiency of the machine tool by the following formula:

[0082] η=m / m1×100% (1)

[0083] m=m1-m2-m3 (2)

[0084] m1=ρ×v1 (3)

[0085] m3=c×v2 (4)

[0086] Among them, η is the dust removal efficiency, m is the theoretical dust removal mass, m1 is the mass consumption of processing materials, ρ is the density of composite materials, v1 is the volume consumed by composite materials, m2 is the mass of deposited chips in the processing area, m3 is the mass of dust floating in the processing area, c is the second dust concentration value, and v2 is the volume of the processing area.

[0087] This technical solution further provides a method for calculating dust removal efficiency. The theoretical mass of material processed is calculated as m1 = ρ (composite material density) × v1 (composite material consumed). The mass of deposited chips in the processing area is measured by weighing, m2. The second dust concentration value c is measured, and the mass of dust floating in the processing area is approximately m3 = c × v (processing area volume). The theoretical dust removal mass can be calculated as m = m1 - m2 - m3 using the formula, and the dust removal efficiency is η = m (theoretical dust removal mass) / m1 (theoretical processing mass) × 100%. This makes it possible to more accurately determine dust removal efficiency and facilitate adjustments to the follow-up dust removal system and the environmental dust removal system.

[0088] In one feasible implementation, the machine tool's follow-up dust removal system and ambient dust removal system are adjusted in their layout and configuration, and steps 101 to 104 are repeated until the dust removal efficiency is greater than or equal to the target efficiency. This allows the machine tool's dust removal efficiency to be greater than or equal to the target efficiency, enabling the machine tool to meet the requirements for processing composite materials.

[0089] Example

[0090] In this technical solution, the evaluation method of machine tool dust removal efficiency includes the following steps:

[0091] 1. Determine the follow-up dust removal detection point, environmental dust removal detection point and operator position detection point on the machine tool.

[0092] 2. Start the machine tool and run it for 5 minutes to ensure that all equipment is in normal working condition.

[0093] 3. Process the composite material at the selected processing speed and tool for 5 minutes, during which the dust extraction system is turned off.

[0094] After 4.5 minutes, measure the first dust concentration value at the detection point.

[0095] 5. Now turn on the dust removal system and run it for 3 minutes.

[0096] 6. After 3 minutes, measure the second dust concentration value at the detection point.

[0097] 7. Each test point shall be carried out in this manner.

[0098] 8. After processing, the collected dust samples are brought back to the laboratory and accurately weighed using an electronic scale to calculate the dust mass at different detection points and under different working conditions.

[0099] like Figures 1 to 7 As shown, according to the second aspect of the embodiment of the present application, a machine tool is proposed, including: a machine tool body 110, the machine tool body 110 includes a workbench 111 and a processing body 112; a follow-up dust removal system 120, the follow-up dust removal system 120 is used to follow the movement of the processing body 112 and perform mobile dust removal; an environmental dust removal system 130, the environmental dust removal system 130 is arranged on the machine tool body 110, and is used to statically adsorb dust generated during the processing of the processing body 112; wherein, the layout position and style of the follow-up dust removal system 120 and the environmental dust removal system 130 are determined based on the evaluation method of the machine tool dust removal efficiency such as any of the above-mentioned technical solutions.

[0100] The arrangement position and style of the follow-up dust removal system 120 and the environmental dust removal system 130 of the machine tool provided in the embodiment of the present application are determined based on the evaluation method of the machine tool dust removal efficiency such as any of the above-mentioned technical solutions. Therefore, the machine tool has all the beneficial effects of the evaluation method of the machine tool dust removal efficiency of the above-mentioned technical solutions. Based on this, the machine tool can meet the high dust collection efficiency processing of composite materials, which will not be elaborated here.

[0101] like Figures 1 to 7 As shown, Figure 1 The elliptical area in the figure is the area where the maze-like gap 123 is located. In a feasible embodiment, the follow-up dust removal system 120 includes: a fixed part 121 and a rotating part 122, the fixed part 121 is slidably connected to the machine tool body 110, and the rotating part 122 is rotatably connected to the fixed part 121; wherein, a maze-like gap 123 is left between the rotating part 122 and the fixed part 121; wherein, along the cross section in the height direction of the follow-up dust removal system 120, the cross section of the maze-like gap 123 is a broken line, and the broken line includes at least four turning points.

[0102] In this technical solution, it is taken into consideration that a large gap is reserved between the fixed disk and the turntable of the follow-up dust removal system 120 in the traditional technology, which causes a partial loss of suction and directly affects the dust removal effect. Afterwards, through optimization, a sealing ring is added between the fixed disk and the turntable, which can effectively reduce the loss of suction. However, there are also defects. If the fixed disk and the turntable are too tightly fitted, it will affect the rotation of the C-axis. If they are too loose, there will be air leakage. In addition, the sealing ring is prone to aging, and the gap between the fixed disk and the turntable is difficult to control. A labyrinth-shaped gap 123 is reserved between the rotating part 122 and the fixed part 121 of the follow-up dust removal system 120 provided in the embodiment of the present application. The cross section of the labyrinth-shaped gap 123 along the height direction of the follow-up dust removal system 120 is in the shape of a broken line. The broken line includes at least four turning points, which does not affect the rotation of the C-axis, but also improves the sealing and improves the dust removal efficiency.

[0103] like Figures 1 to 7 As shown, in a feasible embodiment, the rotating part 122 includes: an adapter housing 1221, the adapter housing 1221 is rotatably connected to the fixed part 121, and a labyrinth-shaped gap 123 is left between the adapter housing 1221 and the fixed part 121; a dust collecting cover 1222, at least two servo electric cylinders 1223, the servo electric cylinders 1223 are relatively arranged on the adapter housing 1221, and the output ends of the servo electric cylinders 1223 are connected to the dust collecting cover 1222; a first dust collecting port 1224 and a second dust collecting port, the first dust collecting port 1224 and the second dust collecting port are opened on the dust collecting cover 1222, tangent to the outer wall of the dust collecting cover 1222, and the first dust collecting port 1224 and the second dust collecting port are staggered along the height direction of the dust collecting cover 1222. The telescopic length of the dust collecting cover 1222 can be controlled to match tools of different lengths, reduce the gap between the dust collecting cover 1222 and the workpiece, and improve dust removal efficiency.

[0104] In this technical solution, considering that the traditional follow-up dust removal port adopts a left-right symmetrical layout, which easily offsets part of the suction force and affects the dust collection effect, the rotating part 122 provided in the embodiment of the present application includes a first dust collection port 1224 and a second dust collection port. The first dust collection port 1224 and the second dust collection port are opened on the dust collection cover 1222, and are arranged tangent to the outer wall of the dust collection cover 1222. The first dust collection port 1224 and the second dust collection port are staggered along the height direction of the dust collection cover 1222. After the dust collection is turned on, a vortex effect can be generated, which effectively improves the dust collection effect.

[0105] like Figures 1 to 7 As shown, in a feasible embodiment, the environmental dust removal system 130 includes: a plurality of sedimentation dust collecting ports 131, which are opened on the machine tool body 110. When the environmental dust removal system 130 is started, the direction of the airflow through the sedimentation dust collecting ports 131 is perpendicular to the plane direction of the workbench 111; a plurality of first lateral dust collecting ports 132, and the plurality of first lateral dust collecting ports 132 are located on the peripheral side of the workbench 111. When the environmental dust removal system 130 is started, the direction of the airflow through the sedimentation dust collecting ports 131 is parallel to the plane direction of the workbench 111 or the angle between the direction of the airflow and the plane of the workbench 111 is an acute angle; wherein, the distance between the sedimentation dust collecting port 131 and the workbench 111 is less than or equal to 0.5m.

[0106] In this technical solution, the structural composition of the environmental dust removal system 130 is further provided. Considering that the environmental dust removal system 130 currently equipped on machine tools has a low dust removal efficiency due to the dust removal port being far away from the processing area, it cannot meet customer needs, and dust overflows, polluting the production environment and easily causing safety accidents. Based on this, the environmental dust removal system 130 provided in the embodiment of the present application can include a sedimentation dust collection port 131 and a first lateral dust collection port 132. The sedimentation dust collection port 131 can absorb and collect dust downward, and the first lateral dust collection port 132 can be closer to the workbench 111. The first lateral dust collection port 132 is as close as possible to the surface of the workbench 111 to achieve a better dust collection effect.

[0107] like Figures 1 to 7 As shown, in a feasible embodiment, the machine tool also includes: an AGV mobile unit 113, the workbench 111 is arranged above the AGV mobile unit 113, and the environmental dust removal system 130 also includes: a plurality of second lateral dust collection ports 133, and the plurality of second lateral dust collection ports 133 are opened on the machine tool body 110, and the opening direction is set flush with the workbench 111.

[0108] In this technical solution, the machine tool may also include an AGV mobile unit 113, which facilitates the movement of the workpiece through the pallet through the AGV mobile unit 113, thereby improving the processing efficiency. In this case, the workbench 111 may be arranged above the AGV mobile unit 113. In this case, a plurality of second lateral dust collection ports 133 may be arranged, and the opening direction of the second lateral dust collection port 133 is set flush with the workbench 111, which can further improve the dust collection efficiency.

[0109] like Figure 9 According to a third aspect of the embodiment of the present application, a method for controlling a machine tool is proposed, which is used to control a machine tool according to any of the above technical solutions. The method for controlling the machine tool includes:

[0110] Step 301: When the machine tool is in operation, obtain the position of the processing body of the machine tool;

[0111] Step 302: Based on the location of the processing body, control some dust collection ports of the environmental dust removal system to be in an open state, so that the environmental dust removal system is concentrated in the working area of ​​the processing body.

[0112] The control method provided in the embodiment of the present application is applied to a machine tool such as any of the above-mentioned technical solutions, so the control method has all the beneficial effects of the machine tool of the above-mentioned technical solutions.

[0113] The control method for the machine tool provided in the embodiment of the present application takes into account that the traditional air volume design for environmental dust removal is air consumption = volume of the internal space of the machine tool * number of air changes. For example: a machine tool with an internal size of 7*4*2.5 (the number of air changes takes the middle value of 150 times / h) has a designed air volume = 7*4*2.5*150 = 10,500 cubic meters / hour; this air volume basically meets the use requirements of the machine tool and can ensure that processing dust does not overflow; this solution is feasible for small machine tools with better sealing, but for large gantry machine tools, the internal space of the machine tool is larger, the calculated air volume is larger, the selected dust collector has a higher power and high energy consumption. Through the control method provided in the embodiment of the present application, the suction port of the environmental dust removal can be automatically opened or closed according to the processing position, and the airflow is concentrated to act on the area being processed, which can improve the dust removal effect.

[0114] For machine tools with large X-axis travel, this solution can effectively reduce energy consumption and costs.

[0115] Take a 16-meter large gantry as an example. The machine tool is 6 meters wide, 20 meters long, and 3 meters high. According to the traditional algorithm, the air volume = 6*20*3*150 = 54,000 cubic meters / hour. The air volume of 54,000 and the wind pressure of 3500Pa theoretically require a set of 55KW dust removal equipment. The machine tool provided by the embodiment of the present application is equipped with multiple first lateral dust collection ports and second lateral dust collection ports on both sides of the machine tool. The first lateral dust collection ports and the second lateral dust collection ports are adjusted according to the position of the crossbeam to remove dust from the processing area. The design is to remove dust from the space 3 meters before and after the AC swing head processing area. The air flow rate designed according to this scheme = 6*(3+3)*3*150 = 16,200 cubic meters / hour, which is only 30% of the previous scheme. Combined with the control method provided by the embodiment of the present application, such as Figure 7 As shown in the figure, the operating area of ​​the machine tool is divided into four areas: A, B, C and D. When the AC swing head is working in area A, the four first lateral dust collection ports closest to the AC swing head are opened. When the AC swing head is processing in area B, the four first lateral dust collection ports closest to the AC swing head are opened, and the remaining first lateral dust collection ports are all closed. It is known that the design air volume is 16,200 cubic meters / hour, the wind pressure is 3,500 Pa, and a total of four first lateral dust collection ports are opened, then the design air volume of each suction port is 4,050 cubic meters / hour, which can greatly improve the dust collection efficiency.
