Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a processing equipment cooling system and a processing equipment cooling control method. Background Technology

[0002] When machining using specialized equipment such as profile grinding machines, profile grinding is employed due to the special shapes being machined. Especially when using grinding wheels as cutting tools, the tool size constantly changes with machining wear, necessitating control over the cooling water supply to maintain cooling efficiency and prevent damage to the machined parts. Summary of the Invention

[0003] To address the existing technical problems, this application provides a cooling system for processing equipment and a cooling control method for processing equipment.

[0004] In a first aspect, embodiments of this application provide a cooling system for a processing equipment, comprising: a nozzle disposed on one side of the processing equipment to be cooled, for spraying coolant onto the processing equipment; a follower mechanism connected to the nozzle, comprising: a first motor, a first lead screw, a second motor, and a second lead screw; the first motor is connected to the first lead screw, and the first lead screw is connected to the nozzle along a first direction, for driving the nozzle to move along the first direction; the second motor is connected to the second lead screw, and the second lead screw is connected to the nozzle along a second direction, for driving the nozzle to move along the second direction; the first direction is perpendicular to the second direction; and a control terminal electrically connected to the first motor and the second motor, for controlling the first motor and / or the second motor to drive the nozzle to move based on the dimensional changes of the cutting tool in the processing equipment, such that the relative distance between the nozzle and the cutting tool remains constant.

[0005] In a second aspect, a cooling control method for a processing equipment is provided, applied to the cooling system of the processing equipment described in any embodiment of this application, comprising: setting a relative distance between a nozzle and a cutting tool; detecting whether the cutting tool has undergone a dimensional change; and, based on the relative distance, in response to detecting a dimensional change in the cutting tool, outputting a control signal to a first motor and / or a second motor to control the first motor and the second motor to drive the nozzle to move, so that the relative distance remains unchanged.

[0006] In the cooling system of the processing equipment provided in the above embodiment, a follower mechanism is provided for the nozzle, including a first motor, a first lead screw, a second motor, and a second lead screw. The first motor is connected to the first lead screw, and the first lead screw is connected to the nozzle along a first direction, for driving the nozzle to move along the first direction. The second motor is connected to the second lead screw, and the second lead screw is connected to the nozzle along a second direction, for driving the nozzle to move along the second direction. The first direction is perpendicular to the second direction. A control terminal is also included, electrically connected to the first motor and the second motor, for controlling the first motor and / or the second motor to drive the nozzle to move based on the size change of the cutting tool in the processing equipment, so that the relative distance between the nozzle and the cutting tool remains constant. Thus, the control terminal can control the nozzle to move in the first direction and / or the second direction through the follower mechanism. In response to changes in the size of the cutting tool in the processing equipment, the nozzle will not remain stationary, but will move to match the size change of the cutting tool to ensure that the relative distance between the nozzle and the cutting tool remains constant. In this way, the coolant sprayed from the nozzle can always maintain a uniform action distance on the cutting tool, so that the nozzle can still provide sufficient cooling effect after the size of the cutting tool changes, improving cooling efficiency.

[0007] The processing equipment cooling control method provided in the above embodiments belongs to the same concept as the corresponding processing equipment cooling system embodiments, and thus has the same technical effect as the corresponding processing equipment cooling system embodiments, which will not be repeated here.

[0011] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0012] In the following description, the phrase "some embodiments" refers to a subset of all possible embodiments. It should be noted that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0013] In the following description, the terms "first," "second," and "third" are used merely to distinguish similar objects and do not represent a specific ordering of the objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0014] One embodiment of this application provides a cooling system for a processing equipment, comprising: Nozzle 1 is disposed on one side of the processing equipment 6 to be cooled, and is used to spray coolant into the processing equipment 6; The follower mechanism 2 connected to the nozzle 1 includes: a first motor 21, a first lead screw 22, a second motor 23, and a second lead screw 24; the first motor 21 is connected to the first lead screw 22, and the first lead screw 22 is connected to the nozzle 1 along a first direction, for driving the nozzle 1 to move along the first direction; the second motor 23 is connected to the second lead screw 24, and the second lead screw 24 is connected to the nozzle 1 along a second direction, for driving the nozzle 1 to move along the second direction; the first direction is perpendicular to the second direction; The control terminal is electrically connected to the first motor 21 and the second motor 23, and is used to control the first motor 21 and / or the second motor 23 to drive the nozzle 1 to move based on the size change of the cutting tool in the processing equipment 6, so that the relative distance between the nozzle 1 and the cutting tool remains unchanged.

[0015] In one embodiment, such as Figure 1 As shown, the first direction is direction a, which is the horizontal direction, and the second direction is direction b, which is the vertical direction. The first direction is perpendicular to the second direction.

[0016] In one embodiment, the processing equipment 6 may include a cutting tool, such as a grinding wheel, which is used to perform cutting, grinding, or other processing operations on the workpiece. A nozzle 1 may be positioned on one side of the cutting tool in the processing equipment 6 to be cooled, for spraying coolant onto the cutting tool. For example, the nozzle 1 may be located on one side of the cutting edge between the cutting tool and the workpiece.

[0017] In one embodiment, nozzle 1 may have a first end and a second end. The first end may be located near the processing equipment 6, such as near the cutting tool, for spraying coolant. The second end may be connected to a pipeline, such as a first pipeline 27 and a second pipeline 28, for spraying coolant from the pipeline through the first end. The diameter of the second end may be larger than that of the first end, thereby increasing the spray pressure.

[0018] In one embodiment, nozzle 1 can be fixedly connected to follower mechanism 2, for example, the movement of follower mechanism 2 will drive the movement of nozzle 1. Both first lead screw 22 and second lead screw 24 are connected to nozzle 1, and the movement of first lead screw 22 and / or second lead screw 24 will drive nozzle 1 to move accordingly. First lead screw 22 moves along a first direction, for example, a horizontal direction, and second lead screw 24 moves along a second direction, for example, a vertical direction. The plane formed by the first and second directions can be the plane where a cutting tool such as a grinding wheel is located, allowing for more precise movement following changes in the size of the cutting tool.

[0019] In one embodiment, the follower mechanism 2 further includes: a first connecting portion 25 and a second connecting portion 26; The first connecting part 25 is connected to the nozzle 1 along the first direction, the first lead screw 22 is disposed in the first connecting part 25 along the first direction, and the first motor 21 is disposed above the first connecting part 25 along the second direction and is connected to the first lead screw 22 along the second direction. The second connecting part 26 is connected to the first connecting part 25 along the second direction, the second lead screw 24 is disposed in the first connecting part 25 along the second direction, and the second motor 23 is disposed above the second connecting part 26 along the second direction and is connected to the second lead screw 24 along the second direction.

[0020] In one embodiment, the first connecting portion 25 may be a box structure, such as one that includes a cavity, and the first lead screw 22 is disposed in the cavity of the first connecting portion 25. The second connecting portion 26 may be a box structure, such as one that includes a cavity, and the second lead screw 24 is disposed in the cavity of the second connecting portion 26. It should be noted that, as Figure 1 and Figure 2In the diagram, dashed lines indicate that the first lead screw 22 is disposed in the cavity of the first connecting part 25 and the second lead screw 24 is disposed in the cavity of the second connecting part 26.

[0021] In one embodiment, one end of the first connecting portion 25, for example, a first end, is connected to the nozzle 1, and the other end of the first connecting portion 25, for example, a second end, is used for the first lead screw 22 to extend into the first connecting portion 25 along the second end, for example, the first lead screw 22 extends into the cavity along the second end of the first connecting portion 25. The first motor 21 can be connected to the first lead screw 22 at the second end of the first connecting portion 25.

[0022] In one embodiment, one end of the second connecting portion 26, for example, the first end, is connected to the nozzle 1, and the other end of the second connecting portion 26, for example, the second lead screw 24, extends into the second connecting portion 26 along the second end, for example, the second lead screw 24 extends into the cavity along the second end of the second connecting portion 26. The second motor 23 can be connected to the second lead screw 24 at the second end of the second connecting portion 26.

[0023] In one embodiment, the first end of the second connecting portion 26 can be connected to the nozzle 1 via the first connecting portion 25. For example, the nozzle 1 is connected to the first end of the first connecting portion 25, and the first end of the second connecting portion 26 can be connected to the first connecting portion 25. The second lead screw 24 controls the movement of the nozzle 1 through the cavity of the second connecting portion 26 and the first connecting portion 25. In this way, the first lead screw 22 and the second lead screw 24 can cooperate to realize the movement of the nozzle 1 in different directions, which is beneficial for accurately following changes in the size of the cutting tool. Moreover, the second connecting portion 26 is connected to the first connecting portion 25 and does not need to be directly connected to the nozzle 1, but it can still achieve driving movement in the second direction.

[0024] In one embodiment, the control terminal can be a device that sets up an application, server, or control interface, such as a computer or mobile device. The control terminal is electrically connected to the first motor 21 and the second motor 23, and can control the first motor 21 and the second motor 23 via numerical control.

[0025] In one embodiment, the control terminal can be used to set the relative distance between the nozzle 1 and the cutting tool. For example, if the relative distance is set to 15mm, then as the size of the cutting tool changes, the control terminal is used to send control signals to the first motor 21 and / or the second motor 23, and control the first lead screw 22 and / or the second lead screw 24 to move through the first motor 21 and / or the second motor 23, thereby driving the nozzle 1 to move so that the relative distance is maintained at 15mm.

[0026] Thus, the control end can control the nozzle 1 to move in the first direction and / or the second direction through the follow-up mechanism 2. In response to the change in the size of the cutting tool in the processing equipment 6, the nozzle 1 will not be fixed, but will move to match the size of the cutting tool to ensure that the relative distance between the nozzle 1 and the cutting tool remains unchanged. In this way, the coolant sprayed by the nozzle 1 can always maintain a uniform action distance on the cutting tool, so that the nozzle 1 can still provide sufficient cooling effect after the size of the cutting tool changes, thereby improving the cooling efficiency.

[0027] In some embodiments, the first lead screw 22 is a ball screw pair, and the first motor 21 is connected to the first lead screw 22 through a reducer and a belt.

[0028] In one embodiment, the first lead screw 22 is a ball screw pair, which may include a lead screw and balls. The first motor 21 may be a Siemens servo motor, etc.

[0029] In one embodiment, the first motor 21 is located above the first lead screw 22 along the second direction, that is, connected to the first lead screw 22 along the second direction. For example, it is connected to the first lead screw 22 along the second direction on the side of the first connecting part 25, which is a side parallel to the second direction.

[0030] In one embodiment, being connected to the first lead screw 22 means being connected to the first lead screw 22 via a reducer and a belt.

[0031] Thus, the first lead screw 22 moves along the first direction, and the first motor 21 is connected to the first lead screw 22 along the second direction, thereby reducing the space occupied in the first direction, i.e., the lateral direction. Furthermore, the belt and reducer are set to facilitate the transmission between the first motor 21 and the first lead screw 22, and optimize the follow-up effect.

[0032] In some embodiments, the second lead screw 24 is a ball screw pair, and the second motor 23 is connected to the second lead screw 24 through a flexible coupling.

[0033] In one embodiment, the second lead screw 24 is a ball screw pair, which may include a lead screw and balls. The second motor 23 may be a Siemens servo motor, etc.

[0034] In one embodiment, the second motor 23 is located above the second lead screw 24 along the second direction, that is, connected to the first lead screw 22 along the second direction. For example, it is connected to the second lead screw 24 along the second direction on the side of the second connecting part 26, which is a side perpendicular to the second direction.

[0035] In one embodiment, connection to the second lead screw 24 means direct connection to the first lead screw 22 via a flexible coupling.

[0036] Thus, the second lead screw 24 moves in the second direction, and the second motor 23 is connected to the second lead screw 24 in the second direction, thereby reducing the space occupied in the first direction, i.e., the lateral direction. Then, the transmission between the second motor 23 and the second lead screw 24 in the same direction can be realized through the flexible coupling.

[0037] In some embodiments, such as Figure 2 As shown, the follower mechanism 2 further includes: a first pipe 27 and a second pipe 28 for supplying coolant to the nozzle 1; The first conduit 27 extends into the first connecting portion 25 along the first direction and is connected to the nozzle 1; the second conduit 28 extends into the second connecting portion 26 and the first connecting portion 25 along the second direction and is connected to the nozzle 1.

[0038] In one embodiment, both the first pipe 27 and the second pipe 28 are water pipes for transmitting coolant. The first pipe 27 can extend and retract in a first direction, and the second pipe 28 can extend and retract in a second direction.

[0039] In one embodiment, the first conduit 27 extends into the first connecting portion 25 along the first direction, which can refer to the first conduit 27 being arranged in a cavity in the first connecting portion 25 along the first direction, the cavity passing through the first connecting portion 25. The cavity where the first conduit 27 is arranged can be the same cavity as the cavity where the first lead screw 22 is arranged, or they can be different cavities.

[0040] In one embodiment, the second conduit 28 extends along the second direction into the second connecting portion 26 and the first connecting portion 25. This can refer to the second conduit 28 being arranged along the second direction within a cavity in the second connecting portion 26. This cavity passes through the second connecting portion 26, and after passing through the second connecting portion 26, the second conduit 28 extends into the first connecting portion 25 and connects to the nozzle 1. The cavity where the second conduit 28 is arranged can be the same cavity as the cavity where the second lead screw 24 is arranged, or it can be a different cavity.

[0041] In one embodiment, the second conduit 28 extends into the first connecting portion 25 and communicates with the first conduit 27, and together they are connected to the nozzle 1.

[0042] In one embodiment, the first pipe 27 and the second pipe 28 may also be connected together to the circulation pipe 4 to receive coolant from the circulation pipe 4.

[0043] Thus, by providing water pipes in the first connecting part 25 and the second connecting part 26 respectively, it can be ensured that when the nozzle 1 moves under the drive of the follower mechanism 2, the continuous delivery of coolant is not affected, thus ensuring uninterrupted cooling effect.

[0044] In some embodiments, the cooling system of the above-mentioned processing equipment may further include: Water tank 3 is used to store coolant; the water tank 3 includes at least a thermostat 31 and a water pump 32, the thermostat 31 is used to control the temperature of the coolant, and the water pump 32 is used to pump the coolant into the circulation pipeline 4. The circulation pipeline 4 is connected to the water tank 3, the nozzle 1 and the processing equipment 6 respectively, and is used to transport the coolant from the water tank 3 to the nozzle 1, and to recover the coolant from the processing equipment 6 and transport it back to the water tank 3; A flow monitoring device 5 is installed on the circulation pipeline 4 and electrically connected to the control terminal, used to monitor the flow rate of coolant in the circulation pipeline 4 and report it to the control terminal. The control terminal is also used to control the processing equipment 6 to stop running and / or output alarm information when the coolant flow rate is lower than a preset value.

[0045] In one embodiment, such as Figure 3 As shown, the coolant stored in the water tank 3 has its temperature controlled by the thermostat 31 and is pumped to the circulation pipeline 4 by the water pump 32. The circulation pipeline 4 delivers the coolant to the nozzle 1 to spray and cool the processing equipment 6. The coolant in the processing equipment 6 is then transported back to the water tank 3 via the circulation pipeline 4.

[0046] In one embodiment, the circulation line 4 delivers coolant to the nozzle 1, which may refer to the circulation line 4 delivering coolant to the nozzle 1 via the first line 27 and / or the second line 28.

[0047] In one embodiment, the flow monitoring device 5 can be used to monitor the flow rate of coolant in the circulation pipe 4. For example, the flow monitoring device 5 can be installed in the part of the circulation pipe 4 that outputs coolant to the nozzle 1, or it can be installed in the part of the circulation pipe 4 that transports coolant back to the water tank 3.

[0048] In one embodiment, the water tank 3 is connected to the circulation pipe 4 via a first outlet, for conveying coolant to the circulation pipe 4 through the first outlet. Additionally, the processing equipment 6 can also be connected to the circulation pipe 4 via a second outlet, for conveying coolant back to the water tank 3 through the second outlet. The outlet flow rates of the first outlet and / or the second outlet are greater than a fixed flow rate value, thereby ensuring smooth circulation, preventing overflow, and achieving a balance between inflow and outflow water.

[0049] In one embodiment, the water pump 32 can be a cooling pump with a flow rate greater than a preset flow rate and a head greater than a preset head, thereby providing high-pressure, high-flow-rate coolant.

[0050] In one embodiment, the thermostat 31 can be set to a preset temperature to control the coolant temperature within ±2°C of the preset temperature.

[0051] Thus, the constant temperature and high pressure delivery of coolant can be achieved through the water tank 3, the constant temperature device 31 and the water pump 32. The circulation of coolant can be achieved through the circulation pipeline 4. The flow monitoring device 5 can achieve precise monitoring of coolant flow. When the coolant is insufficient, the processing can be stopped or an alarm can be triggered in time through the control terminal to protect the parts from damage.

[0052] In some embodiments, the nozzle 1 includes a water outlet; At least one of the number of outlet layers, outlet shape, outlet size, and outlet angle of the nozzle 1 is matched with the shape of the part to be processed in the processing equipment 6.

[0053] In one embodiment, the number of outlet layers can be 1 layer, 2 layers, or other layers. When the number of layers is 1, a single-layer outlet is formed; when the number of layers is 2, a double-layer outlet is formed.

[0054] Here, nozzle 1 may include a water outlet and a nozzle component.

[0055] In one embodiment, the outlet shape may include the outlet cross-sectional shape and / or the outlet cavity shape, for example, it may include a needle outlet, a contoured wire cutting (i.e., contoured wire cutting) outlet, etc.

[0056] In one embodiment, the outlet size may include at least one of the following: outlet depth, outlet cross-sectional width, outlet cross-sectional length, and outlet cross-sectional area.

[0057] In one embodiment, the outlet angle refers to the angle between the outlet cross-section and nozzle 1, which is the angle at which the coolant is sprayed out from the outlet.

[0058] In one embodiment, matching the shape of the part to be processed can refer to matching at least one of the following: the shape, size, required cutting amount, and size of the cutting edge or machined surface of the part to be processed. Processing can include cutting or other operations. The cutting edge refers to the edge of the part to be processed cut by the cutting tool in the processing equipment 6, and the machined surface can refer to the surface of the part to be processed to change its shape and / or size.

[0059] In one embodiment, the outlet size includes at least: the outlet cross-sectional width; If the size of the processing surface of the part to be processed does not exceed a preset threshold, the number of outlet layers is two, and / or the cross-sectional width of the outlet is less than a preset width; When the dimension of the surface to be processed of the part exceeds a preset threshold, the width of the outlet cross-section is greater than a preset width.

[0060] In one embodiment, the processing surface size may include at least one of the processing surface area, processing surface width, and processing surface length. The processing surface size not exceeding a preset threshold may refer to the processing surface area not exceeding a preset area threshold, etc.

[0061] In one embodiment, when the machining surface size of the part to be processed does not exceed a preset threshold, the process may include: when the machining surface size of the part to be processed does not exceed the preset threshold, and the required cutting amount of the part to be processed exceeds a preset cutting amount. The cutting amount can be represented by at least one of the following: the area, width, length, and cutting time required for the part to be processed.

[0062] Thus, when the machining surface size is small and the cutting volume is large, using a double-layer water outlet and / or selecting a water outlet with a smaller width can achieve centralized cooling and obtain a more suitable cooling effect.

[0063] In one embodiment, when the machining surface size of the part to be processed exceeds a preset threshold, it may include: when the machining surface size of the part to be processed exceeds the preset threshold, and the required cutting amount of the part to be processed does not exceed a preset cutting amount.

[0064] In one embodiment, if the dimension of the machined surface of the part to be processed exceeds a preset threshold, the width of the outlet cross-section is greater than a preset width, and / or the nozzle shape can be flat. Here, "flat nozzle shape" can refer to a nozzle shape such as a duckbill shape.

[0065] In this way, when the forming surface is large and the cutting amount is small, using a widened duckbill nozzle for cooling can achieve a wider spray coverage area, thereby improving the cooling effect.

[0066] In one embodiment, when the machining surface of the part to be processed is a special-shaped surface, the outlet shape can be a contour-cut outlet. Here, the special-shaped surface can refer to an irregular surface, etc., and the contour-cut outlet can operate based on the principle of contour cutting. For example, the contour-cut outlet can follow the cutting process of the special-shaped surface.

[0067] In one embodiment, when the cutting edge or machined surface is too narrow, such as when the width is below a preset lower limit, i.e., the cooling position is narrow, and / or when the cutting edge or machined surface is blocked, the outlet and the nozzle can be connected by a copper tube, thereby extending the tube by embedding.

[0068] In one embodiment, at least one of the number of outlet layers, outlet shape, outlet size, and outlet angle of the nozzle 1 is matched with the dressing method of the cutting tool in the processing equipment 6.

[0069] Here, the dressing methods for cutting tools can include two types: arbitrary dressing of disc wheels and dressing of forming wheels, which are used to dress cutting tools such as grinding wheels.

[0070] In one embodiment, when the dressing method is arbitrary dressing of the disc wheel, the outlet and the nozzle can be connected by a copper pipe. The nozzle and / or outlet can be flat, such as duckbill shape, so that the water volume is concentrated during the cooling process, and the copper has good ductility and is easy to adjust.

[0071] In one embodiment, when the dressing method is forming wheel dressing, at least one of the number of outlet layers, outlet shape, outlet size, and outlet angle of the nozzle 1 can also be matched with the integrated width of the dressing. The integrated width can characterize the actual contact width between the forming wheel and the grinding wheel.

[0072] For example, if the integrated width is less than the preset integrated width, the number of outlet layers can be two, and / or the nozzle and / or outlet can be flat, such as duckbill type, etc., thereby achieving centralized cooling based on the double-layer duckbill outlet, which is more suitable for cases with small integrated width. Here, the preset integrated width can be 40mm, etc.

[0073] For example, if the integrated width is greater than or equal to the preset integrated width, the nozzle and / or outlet shape can be needle-shaped, and the length of the needle-shaped nozzle can be positively correlated with the integrated width. Thus, using a customized length needle nozzle can better match trimming scenarios with a larger contact surface.

[0074] Thus, by designing a dedicated nozzle 1 according to the shape characteristics of different parts, the best directional cooling effect can be achieved.

[0075] This application also provides a cooling control method for processing equipment, applicable to the cooling system of processing equipment described in any one or more of the foregoing embodiments, such as... Figure 4 As shown, the method may include: S10: Set the relative distance between the nozzle and the cutting tool; S20: Detect whether the cutting tool has undergone dimensional changes; S30: Based on the relative distance, in response to detecting a change in the size of the cutting tool, output a control signal to the first motor and / or the second motor to control the first motor and the second motor to drive the nozzle to move, so that the relative distance remains unchanged.

[0076] In one embodiment, the above method can be applied to the control terminal of a processing equipment cooling system. Setting the relative distance between nozzle 1 and the cutting tool can refer to setting the relative distance between nozzle 1 and the cutting tool based on detected input operations. Here, input operations can refer to input operations to the control terminal via a user interface or buttons, etc.

[0077] In one embodiment, the relative distance can refer to the distance between the nozzle 1 and the cutting edge or cutting point of the workpiece being cut by the cutting tool. For example, the relative distance can be set to 15mm, etc.

[0078] In one embodiment, a change in the size of the cutting tool can refer to a reduction in size due to tool wear. For example, step S20 can be performed after the cutting tool starts running. Step S20 may include: determining whether the cutting tool has undergone a size change based on initial and current coordinate data. This step may include: acquiring the initial coordinate data of the cutting tool; acquiring the current coordinate data of the cutting tool; determining whether the current coordinate data has changed compared to the initial coordinate data; and determining that the cutting tool has undergone a size change in response to a change in the current coordinate data.

[0079] Here, the coordinate data may include multiple coordinate data corresponding to the center and / or edge of the cutting tool. For example, the coordinate data corresponding to the center may refer to the coordinate data corresponding to the center of the cutting tool or the geometric center, and the coordinate data corresponding to the edge may refer to the coordinate data corresponding to multiple preset points on the edge of the cutting tool, etc.

[0080] In one embodiment, outputting control signals to the first motor 21 and / or the second motor 23 in response to detecting a change in the size of the cutting tool based on the relative distance may include: determining the amount of size change of the cutting tool in response to detecting a change in the size of the cutting tool; determining the amount of displacement required for the nozzle 1 to move or the target coordinate data to which it needs to move based on the relative distance and the amount of size change; and outputting control signals to the first motor 21 and / or the second motor 23 based on the amount of displacement or the target coordinate data.

[0081] In one embodiment, outputting control signals to the first motor 21 and / or the second motor 23 in response to detecting a change in the size of the cutting tool, based on the relative distance, may include: determining the current coordinate data of the cutting tool in response to detecting a change in the size of the cutting tool; determining the amount of displacement that the nozzle 1 needs to move or the target coordinate data to which it needs to move, based on the relative distance and the current coordinate data; and outputting control signals to the first motor 21 and / or the second motor 23 based on the amount of displacement or the target coordinate data.

[0082] In one embodiment, the displacement may include displacement in a first direction and / or a second direction, and the coordinate data may be coordinate data based on a coordinate system formed by the first and second directions.

[0083] In this way, when the cutting tool changes size due to wear, the motor can be automatically controlled based on a pre-set relative distance, thereby driving the nozzle 1 to move to a position where the cutting tool maintains the same relative distance, ensuring that the cooling effect is not affected by the wear of the cutting tool.

[0084] In some embodiments, detecting whether the cutting tool has undergone dimensional changes includes: Obtain the initial coordinate data of the cutting tool; Obtain the current coordinate data of the cutting tool; Determine whether the current coordinate data has changed compared to the initial coordinate data; In response to a change in the current coordinate data, it is determined that the cutting tool has undergone a dimensional change.

[0085] In one embodiment, the initial coordinate data may refer to the coordinate data of the cutting tool when the relative distance between the nozzle 1 and the cutting tool is set. The current coordinate data may refer to the coordinate data of the cutting tool detected in real time during the operation of the processing equipment 6.

[0086] In one embodiment, acquiring the current coordinate data of the cutting tool may include: acquiring the current coordinate data of the cutting tool based on a predetermined period. For example, the predetermined period may be 100ms, 200ms, or 500ms, that is, the current coordinate data of the cutting tool is periodically collected according to the predetermined period, so as to respond promptly to changes in the size of the cutting tool.

[0087] In one embodiment, a change in current coordinate data can mean that the change in current coordinate data compared to the initial coordinate data is not zero, or the change in current coordinate data compared to the initial coordinate data is greater than a preset change, or the change ratio is greater than a preset ratio.

[0088] In one embodiment, a change in current coordinate data can mean that at least one point in the current coordinate data has a change that is not zero compared to the initial coordinate data, or that the change in the current coordinate data is greater than a preset change, or that the change ratio is greater than a preset ratio.

[0089] In this way, based on the changes in the coordinate data of the cutting tool, it is possible to more accurately determine whether its size has changed, thereby enabling more sensitive detection of cutting tool wear and timely movement of nozzle 1.

[0090] In some embodiments, the cooling system of the processing equipment further includes a flow monitoring device 5; the method further includes: Receive the coolant flow rate sent by the flow monitoring device; The coolant flow rate is compared with a preset value; In response to the coolant flow rate being lower than the preset value, the processing equipment 6 is controlled to stop operating and / or an alarm message is output.

[0091] In one embodiment, the flow monitoring device 5 can transmit the coolant flow rate at a predetermined transmission frequency. That is, receiving the coolant flow rate transmitted by the flow monitoring device 5 can include receiving the coolant flow rate transmitted by the flow monitoring device 5 at a predetermined reception frequency. For example, the predetermined reception frequency is equal to the predetermined transmission frequency, such as 10 times / second.

[0092] In one embodiment, responding to the coolant flow rate being lower than the preset value may include: responding to the coolant flow rate being lower than the preset value and the duration reaching a preset upper limit value. Here, the duration refers to the coolant flow rate remaining lower than the preset value for a continuous period, and the preset upper limit value may be 500ms, 1s, etc.

[0093] In one embodiment, the preset value can be a fixed value, or it can be a value determined based on at least one of the cutting speed, consumption rate, and relative distance of the cutting tool.

[0094] For example, the cutting speed of a cutting tool is positively correlated with a preset value. The faster the cutting speed, the higher the heat generated, and the higher the required coolant flow rate, i.e., the preset value.

[0095] For example, the consumption rate of the cutting tool is positively correlated with the preset value. The faster the consumption rate, the higher the cutting speed, and the higher the required coolant flow rate, i.e., the preset value.

[0096] For example, the relative distance is positively correlated with the preset value. The greater the relative distance, the more coolant is needed to achieve cooling, that is, the higher the preset value.

[0097] In one embodiment, before comparing the coolant flow rate with a preset value, the method may further include: acquiring initial coordinate data of the cutting tool; acquiring current coordinate data of the cutting tool; determining the rate of change of the current coordinate data compared to the initial coordinate data; and adjusting the preset value based on the rate of change.

[0098] Here, the rate of change represents the rate at which the cutting tool is consumed. This rate of change can be determined based on the working time of the cutting tool and the amount of change compared to the initial coordinate data. The working time refers to the duration of operation of the cutting tool after the relative distance is set; operation may include actions such as cutting.

[0099] In one embodiment, controlling the machining equipment 6 to stop operating may include controlling the cutting tool to stop operating, or controlling the cutting tool to reduce the cutting speed to a preset speed, etc.

[0100] In one embodiment, outputting alarm information may include at least one of the following methods: outputting alarm information based on beeping, flashing, text, graphics, and voice.

[0101] In this way, when the coolant flow rate decreases and fails to provide a cooling effect, the abnormality can be detected in time and cutting can be stopped or an alarm can be issued, thereby protecting the parts from damage.
