[0070] The application will be further described in detail below with reference to the accompanying drawings.

[0071] In an embodiment, as shown in the figure, the application discloses a numerical control machining control method of a three-way valve, specifically comprising the following steps: Figure 1

[0072] S10: Obtain turning thread data of a current three-way valve, wherein the turning thread data comprises turning thread depth and turning thread turns.

[0073] Specifically, the turning thread data of each valve port of the current three-way valve in the turning process is obtained by an infrared imaging device, wherein the turning thread data comprises turning thread depth between adjacent thread turns, and turning thread turns of each valve port.

[0074] S20: Calculate turning error between the current three-way valve and a preset turning size according to the turning thread depth and the turning thread turns.

[0075] Specifically, as shown in the figure, step S20 specifically comprises the following steps: Figure 2

[0076] S201: Calculate turning thread depth difference and turning thread turn difference between adjacent turning threads according to the turning thread depth and the turning thread turns, respectively.

[0077] Specifically, according to the turning thread depth and the turning thread turns of the same valve port, and according to the spiral sequence of the thread, the turning thread depth difference and the turning thread turn difference between adjacent turning threads are calculated, wherein the turning thread depth difference is the turning depth change between adjacent turning threads, and the turning thread turn difference is the difference between the turning turns of the previous turning three-way valve at the current valve port and the turning turns of the current valve port of the current three-way valve.

[0078] S202: Calculate the difference value between the turning thread depth difference, the turning thread turn difference and the corresponding preset turning size, respectively, to obtain the turning error between the current three-way valve and the preset turning size.

[0079] ​​Specifically, the preset turning size of the current three-way valve is obtained according to the current turning drawing of the three-way valve, including the turning depth of the valve port, the number of thread turns and the turning depth of the thread, and according to the corresponding turning type, the difference between the turning thread depth of the current three-way valve and the preset turning depth is calculated, and the difference between the turning thread number of the current three-way valve and the preset turning size is calculated, which is helpful to judge whether the current turning thread number difference is different from the last turning number or different from the preset turning size, so as to trace the root cause of the current turning number difference and accurately judge, so as to take the calculated depth interpolation and number difference as the turning error of the current three-way valve.

[0080] S30: Obtain the tool calling sequence of the current three-way valve during thread turning, and evaluate the tool wear value of the worn tool according to the turning error and the tool calling sequence.

[0081] Specifically, as shown in Figure 3 the step S30 specifically includes the following steps:

[0082] S301: When the turning error occurs in the current three-way valve, the tool calling sequence of the current three-way valve is obtained.

[0083] Specifically, when the turning error occurs in the current three-way valve, that is, the turning thread of the current three-way valve has turning depth and / or turning number error, the tool calling sequence of the current three-way valve is obtained through the numerical control machining program of the current three-way valve.

[0084] S302: According to the tool calling sequence and the turning error, the turning position of the target turning tool corresponding to the turning error is found.

[0085] Specifically, according to the tool calling sequence and the turning error, the target turning tool that produces the corresponding turning error is found in the tool, and the turning position of the target turning tool in the current three-way valve is found.

[0086] S303: According to the turning position, the last turning parameter and the next turning parameter of the target turning tool are obtained, and the adjacent turning error value between the turning error and the last turning parameter, the next turning parameter is calculated respectively.

[0087] Specifically, according to the turning position, the last turning tool and the next turning tool of the target turning tool are obtained, and the last turning parameter corresponding to the last turning tool and the next turning parameter corresponding to the next turning tool are obtained, wherein the last turning parameter and the next turning parameter are the turning position, the turning depth and the turning number of the corresponding tool on the current three-way valve, and the adjacent turning error value corresponding to the last turning parameter and the next turning parameter is calculated respectively, wherein the adjacent turning error value includes the turning number error and the turning depth error.

[0088] S304: evaluating a tool wear value of the target turning tool with wear according to the adjacent turning error value, to obtain a tool wear evaluation parameter of the target turning tool.

[0089] Specifically, the tool wear value of the target turning tool with wear is evaluated according to the adjacent turning error value sequentially between the previous turning tool, the target turning tool and the next turning tool. For example, the turning error value of the previous turning tool will affect the starting turning point of the target turning tool. When the target turning tool wears to a certain extent, the starting turning position of the target turning tool is higher than the ending turning position of the previous turning tool, or the ending turning position of the target turning tool is higher than the starting turning position of the next turning tool, then the gradient thread connection error is prone to occur at the connection position, so the tool wear value of the target turning tool is evaluated according to the thread connection error at the connection position, to obtain the tool wear evaluation parameter of the target turning tool.

[0090] In an embodiment, in order to replace the damaged tool in time and reduce the unqualified rate of the overall finished product during batch production of the three-way valve, as shown in Figure 4 The step S304 further includes:

[0091] S3041: judging whether the target turning tool reaches the damaged degree requiring replacement according to the tool wear evaluation parameter.

[0092] Specifically, whether the target turning tool reaches the damaged degree requiring replacement is judged according to the tool wear evaluation parameter. For example, the maximum turning error value of the current three-way valve is set according to the allowable error range of the three-way valve, including the maximum error value of the turning depth and the maximum error value of the turning number. When the real-time turning error of the target turning tool reaches the preset maximum turning error value, it is determined that the tool wear evaluation parameter of the target turning tool reaches the maximum wear limit value, and then the target turning tool reaches the damaged degree requiring replacement.

[0093] S3042: searching for a replacement tool matching the target turning tool in a preset tool library when the target turning tool needs to be replaced.

[0094] Specifically, when the target turning tool needs to be replaced, a replacement tool matching the target turning tool is searched for in a preset tool library. For example, the replacement tool matching the target turning tool is searched for in the preset tool library according to the size specification, the corresponding tool sharpness and the turning angle of the turning tool, so that the turning effect of the replacement tool corresponds to that of the target turning tool.

[0095] S3043: acquiring a real-time turning progress of a next three-way valve to be turned, and when the real-time turning progress reaches the turning position where the turning error exists, controlling the replacement tool to replace the target turning tool.

[0096] Specifically, the real-time turning progress of the next three-way valve to be turned is determined according to the real-time turning number of the next three-way valve to be turned, when the real-time turning progress reaches the three-way valve turning position where the turning error exists, that is, the target turning tool needs to be called to turn the next three-way valve to be turned, the replacement tool is controlled to replace the target turning tool, when the numerical control machining program of the next three-way valve to be turned calls the target turning tool, the target turning tool is replaced by the replacement tool, and the replacement tool is controlled to turn the next three-way valve to be turned.

[0097] S40: adjusting the turning parameter where the turning error exists according to the tool wear value, and controlling the turning sequence of the next three-way valve to be turned according to the adjusted turning parameter.

[0098] Specifically, as shown in Figure 5 S40 specifically includes the following steps:

[0099] S401: adjusting the turning power of the target turning tool where the turning error exists according to the tool wear value, to obtain the turning adjustment parameter of the target turning tool.

[0100] Specifically, the turning power of the target turning tool where the turning error exists is adjusted according to the tool wear value, for example, when the wear of the target turning tool causes the thread depth of the current three-way valve to be lower than the preset thread depth, the turning power of the target turning tool is increased, so that the target turning tool deepens the turning depth of the current three-way valve, until the requirement of the preset thread depth is met, or when the actual turning number of the target turning parameter is less than or greater than the preset thread number, the turning power and the turning time of the target turning tool are adjusted, until the actual turning number corresponds to the preset thread number, so as to obtain the turning adjustment parameter of the target turning tool.

[0102] Specifically, according to the turning adjustment parameter, the adjacent turning tool of the target turning tool is also adjusted synchronously, according to the turning depth corresponding to the starting turning power of the target turning tool, the turning power of the previous turning tool of the target turning tool is adjusted, so that the turning depth corresponding to the turning power of the previous turning tool corresponds to the initial turning depth of the target turning tool, or, according to the turning end depth of the target turning tool, the turning power of the next turning tool of the target turning tool is adjusted, so that the turning depth corresponding to the turning power of the next turning tool is adapted to the turning end depth of the target turning tool, thereby obtaining the adjacent turning parameters of the adjacent tool.

[0103] S403: Adjust the turning connection time sequence between the target turning tool and the adjacent tool according to the adjacent turning parameters.

[0106] Specifically, according to the adjacent turning parameters corresponding to each adjacent tool, respectively calculate the turning start time and the turning end time of each adjacent tool, such as calculating the start time and the sleep time of the adjacent tool under the current turning power, the sum of the sleep time of the previous turning tool and the start time of the current turning tool is taken as the turning start time of the current turning tool, the sum of the sleep time of the current turning tool and the start time of the next turning tool is taken as the turning end time corresponding to the current turning tool, and so on, to obtain the turning start time and the turning end time of the adjacent tool.

[0107] S4032: Obtain the adjacent tool putting and taking tool time of the corresponding adjacent tool according to the adjacent turning parameters.

[0108] Specifically, according to the adjacent turning parameters, the putting and taking tool time of the corresponding adjacent tool is obtained, such as according to the adjacent turning parameters, the time length of the adjacent turning tool from the tool magazine to the turning end position of the previous turning tool is calculated, thereby obtaining the putting tool time of the adjacent tool, and the time length required for the adjacent turning tool to move from the turning end position to the corresponding storage position of the tool magazine is calculated as the taking tool time of the adjacent tool.

[0109] S4033: According to the turning start time, the turning end time and the corresponding adjacent putting and taking tool time of each adjacent tool, adjust the putting and taking tool time node between each adjacent tool and the target turning tool.

[0110] Specifically, according to the turning start time, the turning end time and the corresponding adjacent tool receiving and releasing time of each adjacent tool, the time length required for the adjacent tool receiving and releasing is calculated, and the time length of the target turning tool receiving and releasing under the current turning power is adjusted according to the receiving time length of the last adjacent tool and the releasing time length of the target turning tool, the receiving time node corresponding to the adjacent tool and the target turning tool is adjusted according to the releasing time length of the next adjacent tool and the receiving time length of the target turning tool, and the releasing time node between the adjacent tool and the target turning tool is adjusted.

[0111] S4034: Obtain the target tool receiving and releasing time corresponding to the turning adjustment parameter, and adjust the turning connection sequence between the target turning tool and the adjacent tool according to the tool receiving and releasing time node and the target tool receiving and releasing time.

[0112] Specifically, the target tool receiving and releasing time node corresponding to the turning adjustment parameter is obtained, that is, after the target turning tool adjusts the turning power, the target tool receiving and releasing time corresponding to the adjusted turning power is obtained, the turning connection sequence between the target turning tool and the adjacent tool is adjusted according to the adjusted target turning tool receiving and releasing time node and the receiving and releasing time of the target turning tool moving from the tool magazine to the corresponding turning position.

[0113] S404: According to the turning connection sequence, the connection sequence of all turning tools of the next three-way valve to be turned is adjusted to obtain the turning sequence parameter for controlling the next three-way valve to be turned.

[0114] Specifically, according to the turning connection sequence, the connection sequence of all turning tools of the next three-way valve to be turned is adjusted in sequence, the last turning depth of the last turning tool is taken as the starting turning depth of the next turning tool, so as to adjust the moving time of each turning tool moving to the corresponding turning position, and the turning power of the current tool is adjusted in combination with the wear condition of the current tool, so as to obtain the start and sleep time of each tool under the current turning power, and the connection sequence of all turning tools is comprehensively adjusted according to the moving time and the start and sleep time of each tool under the current turning power, and the numerical control machining of the next three-way valve to be turned is controlled through the adjusted tool calling sequence.

[0115] In an embodiment, in order to clean the burr in the finished thread of the three-way valve in time and improve the finished product qualification rate of the three-way valve, as shown in Figure 7 As shown in FIG. 4, step S40 further includes:

[0116] S405: After the turning process of the current three-way valve is completed, the inner wall chip data of the current three-way valve is obtained.

[0117] Specifically, after the current three-way valve turning process is completed, that is, all turning tools are returned to the tool magazine, the current three-way valve inner wall chip data is collected by a preset infrared imaging device, including the attachment amount and attachment position of the chip on the inner wall, and other attachment conditions.

[0118] S406: Determine whether the turning thread of the current three-way valve has burrs according to the inner wall chip data.

[0119] Specifically, whether the turning thread of the current three-way valve has burrs is determined according to the inner wall chip data. After the turning process of the current three-way valve is completed, the inner wall of the three-way valve is cleaned by water washing or air blowing, and the inner wall chip attachment condition of the current three-way valve is obtained by the infrared imaging device after cleaning. The inner wall chip attachment condition is analyzed. When one side of the chip is bonded to the inner wall, it indicates that the turning thread of the current three-way valve has burrs.

[0120] S407: When the current three-way valve has thread burrs, determine the adhesion viscosity of the thread burrs on the inner wall of the three-way valve.

[0121] Specifically, when the thread burrs are found on the inner wall of the current three-way valve, the adhesion viscosity on the inner wall is determined according to the attachment volume of the thread burrs on the inner wall of the three-way valve. The larger the attachment volume, the higher the adhesion viscosity, and the more difficult it is to clean the burrs. The smaller the attachment volume, the lower the adhesion viscosity, and the easier it is to clean the thread burr part.

[0122] S408: Adjust the chip cleaning intensity of the current three-way valve according to the adhesion viscosity, and clean the thread burrs according to the adjusted chip cleaning intensity.

[0123] Specifically, in this embodiment, the thread burr cleaning is performed by filling abrasive particles into the three-way valve. The chip cleaning intensity of the abrasive particles is adjusted according to the adhesion viscosity. The higher the adhesion viscosity, the greater the chip cleaning intensity of the abrasive particles. The lower the adhesion viscosity, the smaller the chip cleaning intensity of the abrasive particles. The corresponding thread burrs are cleaned by controlling the extrusion intensity of the abrasive particles, so that a smooth thread inner wall is obtained. The thread burr cleaning is performed by the chip cleaning intensity proportional to the adhesion viscosity of the thread burr.
