Description

Technical Field

[0001] This invention relates to the field of machine tools, and in particular to a chip removal control method for machine tool production and a chip removal device controlled according to the above-described chip removal control method for machine tool production. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting internal and external cylindrical surfaces, internal and external conical surfaces with arbitrary cone angles, complex rotating internal and external curved surfaces, and cylindrical and conical threads on shaft or disc-shaped parts. They can also perform grooving, drilling, reaming, boring, and other machining operations. When machining parts, CNC machine tools often generate a significant amount of chips. This waste cannot be cleaned during processing and can only be manually cleaned after the lathe has stopped. In existing designs, a water gun is typically connected to a water pump to rinse the chips off the workpiece or machining equipment. While convenient, this method wastes water and increases production costs. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a chip control method for machine tool production. By classifying the chip type and setting the corresponding water gun output and water gun usage time, water resources are less likely to be wasted, thus reducing production costs.

[0004] In order to overcome the shortcomings of the prior art, the second objective of this invention is to provide a chip flushing device that does not easily cause water waste and reduces production costs.

[0005] One of the objectives of this invention is achieved through the following technical solution:

[0006] A chip control method for machine tool production includes the following steps:

[0007] S1. Connect the pipeline to the machine tool spindle through the main function outlet. At this time, the water gun is closed, the check valve is closed, the ball valve is closed, and a sealed cavity is formed between the water gun and the check valve. The pressure of the sealed cavity is greater than or equal to the low value set by the pressure switch. The control system controls the water pump to shut down and the main function is disabled.

[0008] S2. Based on user needs, the selection modes are categorized as follows: the first mode is to use only the water gun function, the second mode is to use both the water gun and the main function, and the third mode is to use only the main function.

[0009] S3. The control system controls the operation of the water pump and the on / off state of the solenoid valve according to the mode category:

[0010] If the user selects the first mode: the control system controls the water pump to work and controls the solenoid valve to disconnect, opens the ball valve, the water gun is still in the closed state, the one-way valve is in the open state, and the water pump fills the sealed cavity with fluid and pressurizes it. When the pressure of the sealed cavity reaches the set high value of the pressure switch, the control system senses the signal and controls the water pump to stop working, and measures the standard fluid flow rate in the sealed cavity through the flow meter.

[0011] The location of the chips is obtained by an industrial camera, and the chips are initially classified according to their location: chips located on the surface of the workpiece are classified as Class I chips, and chips located inside the machine tool are classified as Class II chips.

[0012] If the chips are of type I, calculate the required fluid flow rate based on the shape and quantity of the chips. The maximum value of the required fluid flow rate is less than the standard fluid flow rate. Turn on the water gun to rinse the chips. The fluid in the sealed cavity is sprayed out through the water gun, which causes the pressure in the sealed cavity to decrease. When the fluid flow rate in the sealed cavity is lower than the difference between the standard fluid flow rate and the required fluid flow rate, and the pressure in the sealed cavity is greater than or equal to the low value set by the pressure switch, turn off the water gun.

[0013] If the chips are of type II, the target area is divided according to the location of the chips. Based on the size of the chips in each target area and the distance between the chips and the water gun, the target fluid requirement for each target area is calculated. The control system sets the water gun output and water gun usage time for each target area according to the target fluid requirement, and cleans the target areas sequentially from high to low height. The water gun is turned on and the water output is adjusted to the corresponding water gun output through the ball valve. The fluid in the sealed cavity is sprayed out through the water gun, which causes the pressure in the sealed cavity to decrease. When the pressure drops to the low value set by the pressure switch, the control system senses the signal and controls the water pump to work. The one-way valve is in the open state to meet the water supply of the water gun until the last target area is cleaned and the water gun is turned off.

[0014] The chip image is re-acquired using an industrial camera to check the chip removal situation. If the chip is not cleaned properly, step S3 is repeated.

[0015] Furthermore, in step S2, if the user selects the second mode: the control system controls the water pump to work and controls the solenoid valve to open, at which time the fluid can flow out from the main function outlet to cool the tool and workpiece on the main station; the ball valve is opened, the water gun is still in the closed state, the check valve is in the open state, the water pump fills the sealed cavity with fluid and pressurizes it, when the pressure of the sealed cavity reaches the set high value of the pressure switch, the control system senses the signal and controls the water pump to stop working, the main function is deactivated, and the standard fluid flow rate in the sealed cavity is measured by the flow meter;

[0016] An industrial camera acquires an image of the finished workpiece at the machine tool's auxiliary workstation. The required fluid flow rate is calculated based on the shape and quantity of the chips. If the required fluid flow rate is less than the standard fluid flow rate, a water gun is turned on to rinse the chips. Fluid in the sealed cavity is ejected through the water gun, causing a decrease in pressure within the sealed cavity. When the fluid flow rate in the sealed cavity is lower than the difference between the standard fluid flow rate and the required fluid flow rate, and the pressure in the sealed cavity is greater than or equal to the low setting value of the pressure switch, the water gun is turned off. If the required fluid flow rate is greater than the standard fluid flow rate, during use, when the main function is restarted, the control system sets the water output and usage time of the water gun based on the water flow rate at the main function outlet until cleaning is complete, at which point the water gun is turned off.

[0017] Furthermore, in the second mode, the head-flow function curve of the water pump is first obtained, then the head of the water pump is obtained according to the main function outlet pressure, and finally the outlet flow rate of the main function is found in the head-flow function curve based on the calculated head.

[0018] Furthermore, in step S2, if the user selects the third mode: the control system controls the water pump to work and controls the solenoid valve to open, while the control system blocks the pressure switch signal, the fluid can only flow out from the main function outlet.

[0019] Furthermore, in the third mode, the water flow rate of the main functional outlet can be adjusted by a regulating valve.

[0020] The second objective of this invention is achieved by the following technical solution:

[0021] A chip removal device, controlled by any of the chip removal control methods described above for machine tool production, includes a control system, an industrial camera, a water pump, a connector, a water gun, a one-way valve, a pressure switch, and a ball valve. The connector has several interfaces, the water pump is connected to one of the interfaces, a sealed cavity is formed between the one-way valve and the water gun, the pressure switch is used to measure the pressure of the sealed cavity, the ball valve is installed on one of the interfaces, and the ball valve can adjust the water flow rate of the water gun. The industrial camera is used to acquire images of chips inside the workpiece or machine tool. When the pressure of the sealed cavity is greater than or equal to the low set value of the pressure switch, the control system controls the water pump to stop.

[0022] Furthermore, the chip removal device also includes a solenoid valve and a main function outlet, the main function outlet being connected to one of the interfaces, the solenoid valve being disposed between one of the interfaces and the main function outlet, and the control system controlling the opening and closing of the solenoid valve.

[0023] Furthermore, the chip removal device also includes a regulating valve, which is disposed between the interface and the solenoid valve, and the regulating valve is capable of regulating the water flow rate of the main functional outlet.

[0024] Compared to existing technologies, the chip removal control method for machine tool production of the present invention includes the following steps: S1, connecting the pipeline to the machine tool spindle through the main function outlet. At this time, the water gun, check valve, and ball valve are all closed, forming a sealed cavity between the water gun and the check valve. The pressure in the sealed cavity is greater than or equal to the low value set by the pressure switch. The control system controls the water pump to shut down, and the main function is disabled. S2, classifying the selection modes according to user needs: the first mode is to use only the water gun function, the second mode is to use both the water gun and the main function simultaneously, and the third mode is to use only the main function. S3, the control system controls the operation of the water pump and the on / off state of the solenoid valve according to the mode category. After chip removal is completed, an image of the chips is acquired again through an industrial camera to check the chip removal status. If the chips are not cleaned properly, step S3 is repeated. This application, by classifying the chip types, setting the corresponding water gun output and water gun usage time, and adjusting the water gun output through the ball valve, reduces water waste and lowers production costs. This application allows for the control of water pumps and solenoid valves through a control system, enabling the switching of different operating modes based on user needs. It has a wide range of applications and saves resources. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Figure 2 The chip-flush device controlled by the chip-flush control method for machine tool production of the present invention includes a control system, an industrial camera, a water pump 10, a connector 20, a water gun 30, a one-way valve 40, a pressure switch 50, a ball valve 60, a solenoid valve 70, a main function outlet 80, and a regulating valve 90. The connector 20 is provided with several interfaces. The water pump 10 is connected to one interface. A sealed cavity is formed between the one-way valve 40 and the water gun 30. The pressure switch 50 is used to measure the pressure of the sealed cavity. The ball valve 60 is set on one interface and can adjust the water flow rate of the water gun 30. The industrial camera is used to acquire images of chips inside the workpiece or machine tool. When the pressure of the sealed cavity is greater than or equal to the low value set by the pressure switch 50, the control system controls the water pump 10 to be in a stopped state.

[0032] The main function outlet 80 is connected to an interface, and a solenoid valve 70 is located between the interface and the main function outlet 80. The control system controls the opening and closing of the solenoid valve 70.

[0033] The regulating valve 90 is located between an interface and the solenoid valve 70. The regulating valve 90 can regulate the outflow rate of the main functional outlet 80.

[0034] like Figure 1 As shown, this application provides a chip control method for machine tool production, including the following steps:

[0035] S1. Connect the pipeline to the machine tool spindle through the main function outlet 80. At this time, the water gun 30 is closed, the check valve 40 is closed, the ball valve 60 is closed, and a sealed cavity is formed between the water gun 30 and the check valve 40. The pressure of the sealed cavity is greater than or equal to the set low value of the pressure switch 50. The control system controls the water pump 10 to shut down and the main function is disabled.

[0036] S2. Based on user needs, the selection modes are categorized as follows: the first mode is to use only the water gun 30 function, the second mode is to use both the water gun 30 and the main function, and the third mode is to use only the main function.

[0037] S3. The control system controls the operation of water pump 10 and the on / off state of solenoid valve 70 according to the mode category:

[0038] If the user selects the first mode: the control system controls the water pump 10 to work and controls the solenoid valve 70 to disconnect, opens the ball valve 60, the water gun 30 remains closed, the check valve 40 is open, and the water pump 10 fills the sealed cavity with fluid and pressurizes it. When the pressure in the sealed cavity reaches the set high value of the pressure switch 50, the control system senses the signal and controls the water pump 10 to stop working, and measures the standard fluid flow rate in the sealed cavity through the flow meter.

[0039] The location of the chips is obtained by an industrial camera, and the chips are initially classified according to their location: chips located on the surface of the workpiece are classified as Class I chips, and chips located inside the machine tool are classified as Class II chips.

[0040] If the chips are of type I, calculate the required fluid flow rate based on the shape and quantity of the chips. If the maximum required fluid flow rate is less than the standard fluid flow rate, turn on the water gun 30 to rinse the chips. The fluid in the sealed cavity is sprayed out through the water gun 30, which causes the pressure in the sealed cavity to decrease. When the fluid flow rate in the sealed cavity is lower than the difference between the standard fluid flow rate and the required fluid flow rate, and the pressure in the sealed cavity is greater than or equal to the low value set by the pressure switch 50, turn off the water gun 30.

[0041] If the chips are of type II, the target area is divided according to the location of the chip distribution. Based on the size of the chips in each target area and the distance between the chips and the water gun 30, the target fluid demand for each target area is calculated. The control system sets the water output and water gun 30 usage time for each target area according to the target fluid demand, and cleans the target areas in descending order of their height. The water gun 30 is turned on and the water output is adjusted to the corresponding water output through the ball valve 60. The fluid in the sealed cavity is sprayed out through the water gun 30, which causes the pressure in the sealed cavity to decrease. When the pressure drops to the low value set by the pressure switch 50, the control system senses the signal and controls the water pump 10 to work. The one-way valve 40 is in the open state to meet the water supply of the water gun 30 until the last target area is cleaned and the water gun 30 is turned off.

[0042] The chip image is re-acquired using an industrial camera to check the chip removal status. If the chip is not cleaned properly, step S3 is repeated.

[0043] In step S2, the application scenario for selecting the first mode is: after the workpiece is processed, the machine tool stops working, and chip removal is required for the workpiece or the inside of the machine tool; the application scenario for selecting the second mode is: a dual-station machine tool, that is, a machine tool including a main station and a secondary station. The main station usually refers to the station in the processing area, and the secondary station usually refers to the station in the loading area. The main function is to cool the tool and workpiece during spindle cutting. Since the secondary station and the processing area are separated, a water gun 30 can be used to clean the workpiece at the secondary station; the application scenario for selecting the third mode is: during the processing, only the machine tool spindle needs to be cooled down.

[0044] In the first mode, the water gun 30 can collect the debris scattered throughout the machine tool into the collection box, which facilitates subsequent centralized processing, improves the cleaning efficiency of the debris, and enhances the practicality of the CNC machine tool.

[0045] In a preferred embodiment, the pressure loss curve of the sealing cavity can be obtained based on the outlet pressure of the water gun 30 and the fluid flow rate in the sealing cavity. The pressure corresponding to the target fluid demand is found based on the pressure loss curve, and the control system adjusts the speed of the water pump 10 to increase the pressure in the pipeline to the pressure that should be generated under the target fluid demand. Since the water pump 10 has multiple frequencies, the water output of the water gun 30 can be controlled by adjusting the speed of the water pump 10 motor through a frequency converter.

[0046] In step S2, if the user selects the second mode: the control system controls the water pump 10 to work and controls the solenoid valve 70 to open, at which time the fluid can flow out from the main function outlet 80; repeat the operation steps in the first mode, open the ball valve 60, the water gun 30 is still in the closed state, the one-way valve 40 is in the open state, the water pump 10 fills the sealed cavity with fluid and pressurizes it, when the pressure in the sealed cavity reaches the set high value of the pressure switch 50, the control system senses the signal and controls the water pump 10 to stop working, the main function is disabled, and the standard fluid flow rate in the sealed cavity is measured by the flow meter;

[0047] An industrial camera acquires an image of the finished workpiece at the machine tool auxiliary station. The required fluid flow rate is calculated based on the shape and quantity of the chips. If the required fluid flow rate is less than the standard fluid flow rate, the water gun 30 is turned on to rinse the chips. The fluid in the sealed cavity is sprayed out through the water gun 30, resulting in a decrease in the pressure in the sealed cavity. When the fluid flow rate in the sealed cavity is lower than the difference between the standard fluid flow rate and the required fluid flow rate, and the pressure in the sealed cavity is greater than or equal to the low value set by the pressure switch 50, the water gun 30 is turned off. If the required fluid flow rate is greater than the standard fluid flow rate, during the use of the water gun 30, when the main function is turned on again, the control system sets the water output and usage time of the water gun 30 based on the water flow rate of the main function outlet 80 until cleaning is completed, and then the water gun 30 is turned off.

[0048] In the second mode, the head-flow-rate function curve of pump 10 is first obtained. This curve records the correspondence between the head and the outflow rate of the main functional outlet 80. This head-flow-rate function curve can be obtained through actual measurement.

[0049] Then, the head of the water pump 10 is obtained based on the pressure at the main functional outlet 80. Usually, there is a predetermined functional relationship between the measured pressure at the main functional outlet 80 and the head, so the head can be obtained by conversion.

[0050] Finally, based on the calculated head, the effluent flow rate of the main functional outlet 80 is found in the head-flow function curve. In this way, the effluent flow rate of the main functional outlet 80 is indirectly obtained based on the pressure at the outlet of the measuring pipeline.

[0051] In step S2, if the user selects the third mode: the control system controls the water pump 10 to work and controls the solenoid valve 70 to open, while the control system blocks the pressure switch 50 signal. At this time, the fluid can only flow out from the main function outlet 80.

[0052] In the third mode, the flow rate of the main functional outlet 80 can be adjusted by regulating valve 90.

[0053] This application categorizes chip types, sets corresponding water output and usage time for the water gun 30, and adjusts the water output via the ball valve 60, thus minimizing water waste and reducing production costs. Furthermore, this application allows for switching between different operating modes by controlling the water pump 10 and solenoid valve 70 according to user needs, resulting in a wide range of applications and resource conservation.

[0054] This application also relates to a chip-flush device controlled by the above-mentioned chip-flush control method for machine tool production, including a control system, a water pump 10, a connector 20, a water gun 30, a one-way valve 40, a pressure switch 50, a ball valve 60, a solenoid valve 70, a main function outlet 80, and a regulating valve 90. The connector 20 is provided with several interfaces, the water pump 10 is connected to one interface, a sealed cavity is formed between the one-way valve 40 and the water gun 30, the pressure switch 50 is used to measure the pressure of the sealed cavity, the ball valve 60 is provided on one interface, the ball valve 60 can adjust the water flow rate of the water gun 30, and an industrial camera is used to acquire images of chips inside the workpiece or machine tool. When the pressure of the sealed cavity is greater than or equal to the low set value of the pressure switch 50, the control system controls the water pump 10 to be in a stopped state.

[0055] The main function outlet 80 is connected to an interface, and a solenoid valve 70 is located between the interface and the main function outlet 80. The control system controls the opening and closing of the solenoid valve 70.

[0056] The regulating valve 90 is located between an interface and the solenoid valve 70. The regulating valve 90 can regulate the outflow rate of the main functional outlet 80.

[0057] In this application, the water gun 30 and the main functional outlet 80 are connected to a water pump 10 through a connector 20. Multiple functions are achieved through a single water pump 10, saving the need for a separate pump. When using this pipeline device, different modes can be selected according to the user's needs, making it widely applicable, saving resources, and reducing production costs.

[0058] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
