Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a detection structure, a machine tool having the same, and a detection method. Background Art

[0002] In modern manufacturing, CNC machine tools (Computer Numerical Control) have become indispensable processing equipment due to their high precision, high efficiency and degree of automation. The cutting tools on CNC machine tools are key components for completing various cutting tasks. However, due to the complexity of processing conditions, such as material hardness, cutting force, tool wear and other factors, the cutting tools may break or be seriously damaged during the processing, which not only reduces the processing quality and efficiency, but also may cause damage to the machine tool itself and even cause safety accidents.

[0003] Broken tool detection is an important detection technology in the CNC machine tool processing process, which is used to detect whether the tool is broken or damaged during the processing. The broken state of the tool will not only affect the processing accuracy and quality, but also may cause damage to the machine tool and increase maintenance costs.

[0004] Traditional methods of tool breakage detection mainly include visual inspection, acoustic inspection, electrical inspection and mechanical inspection. Among them, the visual inspection method requires manual regular inspection of the tool status, which is time-consuming and labor-intensive, and cannot be effectively observed at high speeds; acoustic inspection determines the tool status by detecting changes in sound during the cutting process, but is easily affected by environmental noise and has low accuracy; electrical inspection relies on changes in the electrical characteristics of the tool, such as current or resistance, but is ineffective for non-conductive tools; mechanical inspection methods such as swing-type inspection devices and tool setting devices installed on the workbench can achieve automated inspection, but have defects such as large detection accuracy errors and the installation position affecting the processing of parts, especially in high-precision processing and narrow working spaces. These problems are particularly prominent.

[0005] For example, when the swing detection device detects the tool, the tool needs to swing outside the working stroke, which not only increases the complexity of the machine tool operation, but also may affect the positioning accuracy of the tool due to improper control of the swing amplitude and speed, and even cause the tool to collide with other parts of the machine tool. Although the tool setting instrument installed on the workbench can detect the tool status to a certain extent, it may interfere with the processing of parts on the workbench due to its fixed position, especially when the workpiece size is large or the workpiece layout is complex, the tool setting instrument may become an obstacle on the processing path, limiting the processing flexibility of the machine tool.

[0006] In summary, the detection methods in the prior art have problems such as poor detection accuracy and the installation position easily affecting the processing of parts. Summary of the invention

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] In modern manufacturing, CNC machine tools (Computer Numerical Control) have become indispensable processing equipment due to their high precision, high efficiency and degree of automation. The cutting tools on CNC machine tools are key components for completing various cutting tasks. However, due to the complexity of processing conditions, such as material hardness, cutting force, tool wear and other factors, the cutting tools may break or be seriously damaged during the processing, which not only reduces the processing quality and efficiency, but also may cause damage to the machine tool itself and even cause safety accidents.

[0041] Broken tool detection is an important detection technology in the CNC machine tool processing process, which is used to detect whether the tool is broken or damaged during the processing. The broken state of the tool will not only affect the processing accuracy and quality, but also may cause damage to the machine tool and increase maintenance costs.

[0042] Traditional methods of tool breakage detection mainly include visual inspection, acoustic inspection, electrical inspection and mechanical inspection. Among them, the visual inspection method requires manual regular inspection of the tool status, which is time-consuming and labor-intensive, and cannot be effectively observed at high speeds; acoustic inspection determines the tool status by detecting changes in sound during the cutting process, but is easily affected by environmental noise and has low accuracy; electrical inspection relies on changes in the electrical characteristics of the tool, such as current or resistance, but is ineffective for non-conductive tools; mechanical inspection methods such as swing-type inspection devices and tool setting devices installed on the workbench can achieve automated inspection, but have defects such as large detection accuracy errors and the installation position affecting the processing of parts, especially in high-precision processing and narrow working spaces. These problems are particularly prominent.

[0043] For example, when the swing detection device detects the tool, the tool needs to swing outside the working stroke, which not only increases the complexity of the machine tool operation, but also may affect the positioning accuracy of the tool due to improper control of the swing amplitude and speed, and even cause the tool to collide with other parts of the machine tool. Although the tool setting instrument installed on the workbench can detect the tool status to a certain extent, it may interfere with the processing of parts on the workbench due to its fixed position, especially when the workpiece size is large or the workpiece layout is complex, the tool setting instrument may become an obstacle on the processing path, limiting the processing flexibility of the machine tool.

[0044] In summary, the detection methods in the prior art have problems such as poor detection accuracy and the installation position easily affecting the processing of parts.

[0045] The main purpose of the present invention is to provide a detection structure, a machine tool having the same and a detection method, so as to solve the problems in the prior art that when detecting a tool, the detection accuracy is poor and the installation position affects the processing of parts.

[0046] First, the present application provides a detection structure, including: an installation unit 1, the installation unit 1 having a first installation surface, and the installation unit 1 is arranged on a foundation to be installed;

[0047] A detection unit 2, which is disposed on the first mounting surface. The detection unit 2 includes a pressure detection component 202. The pressure detection component 202 has a detection end that is adjustable in position, so that the detection end contacts at least part of the component to be detected, so that during the rotation of the component to be detected, pressure detection information is obtained through the contact between the detection end and the detection surface of the component to be detected;

[0048] The control unit is connected to the detection unit 2 to receive pressure detection information and determine the integrity of the component to be detected based on the pressure detection information. The integrity includes a completely intact state, a semi-defective state, and a broken state.

[0049] Specifically, the detection structure provided by the present application includes an installation unit 1 having a first installation surface, and a detection unit 2 is arranged on the first installation surface. The detection unit 2 includes a pressure detection component 202, and the pressure detection component 202 has a detection end with an adjustable position so that the detection end is in contact with at least a portion of the component to be detected, so that during the rotation of the component to be detected, a pressure detection signal is obtained by the contact between the bronze drum detection end and the surface to be detected formed by multiple components to be detected. The control unit also includes a control unit connected to the detection unit 2, and the control unit is used to receive pressure detection information and judge the integrity of the component to be detected based on the pressure detection information, wherein the integrity includes a complete state, that is, the component to be detected has no defects, a semi-defective state, that is, the component to be detected has slight defects and can be used normally after repair, and a broken state, that is, the component to be detected is broken and cannot be used normally.

[0050] The detection structure provided in the present application realizes high-precision detection of the integrity of the tool by setting the detection unit 2 on the first mounting surface of the mounting unit 1. The pressure detection component 202 in the detection unit is designed with a detection end with adjustable position. This design ensures that the detection end can accurately contact the contact surface of the component to be detected (tool) of different lengths and shapes, and even during the rotation of the tool, a stable pressure detection signal can be obtained, thereby comprehensively evaluating the status of the tool. Compared with traditional non-contact detection, this contact pressure detection method can provide more direct and accurate feedback information, and effectively avoid misjudgment caused by interference with the signal of the non-contact detection method.

[0051] The control unit can receive and process the pressure detection information from the pressure detection component 202 in real time, and quickly judge the integrity of the tool, including the intact state, the semi-defective state and the broken state.

[0052] In addition, the detection structure of the present application also has good versatility and flexibility. Since the detection unit is installed at the tool magazine, it not only avoids occupying the workbench processing space, but also can adapt to tools of different sizes and shapes without complicated adjustments to the detection mechanism.

[0053] In summary, the detection structure of the present application achieves high-precision detection while minimizing the impact on machine tool processing efficiency, effectively improving the safety and reliability of machine tool operation, and providing strong technical support for CNC machine tool processing in modern manufacturing.

[0054] Furthermore, the detection unit 2 also includes: a telescopic component 201, which is telescopically arranged on the first mounting surface, and a pressure detection component 202 is arranged at the telescopic end of the telescopic component 201, so that it can move towards or away from the component to be detected under the drive of the telescopic component 201 to adjust the position of the detection end.

[0055] Specifically, the detection unit 2 also includes a telescopic component 201 that is telescopically arranged on the first mounting surface. The telescopic component 201 in this embodiment can be a hydraulic cylinder or a telescopic drive motor. The pressure detection component 202 is arranged at the driving end of the telescopic component 201. The pressure detection component 202 can be driven relatively close to or away from the component to be detected through the action of the telescopic component 201.

[0056] In the specific implementation of the present application, the structural design of the detection unit 2 further enhances its detection accuracy and flexibility. In order to achieve precise contact and pressure detection of the tool, the detection unit 2 includes a telescopic component 201 and a pressure detection component 202. The telescopic component 201 can take a variety of forms, such as a hydraulic cylinder, a telescopic drive motor or other controllable telescopic devices. In this embodiment, it is preferred to use a servo electric cylinder as the telescopic component 201. This is because the servo electric cylinder has the characteristics of high precision, fast response and high stability, and can accurately control its telescopic distance and speed, which is very suitable for broken knife detection scenarios that require precise control.

[0057] The telescopic component 201 is connected to the pressure detection component 202 through its driving end. When the telescopic component 201 contracts or extends, it can drive the pressure detection component 202 to approach or move away from the component to be detected (i.e., the tool). This design can produce corresponding pressure changes according to the state of the tool. Through the precise control of the servo electric cylinder and the high sensitivity of the pressure detection component 202, the present invention can accurately capture the pressure signal changes when the tool is broken or damaged, and realize real-time and accurate detection of the tool integrity state.

[0058] Further, the installation unit 1 comprises: a fixing seat, which is arranged on the foundation to be installed;

[0059] An installation component 10, the installation component 10 is arranged on the fixing seat, so that the detection unit 2 is fixed on the fixing seat through the installation component 10;

[0060] The counter is arranged on the fixing seat and connected to the detection unit 2 to count the number of the components to be detected in a completely intact state, a semi-defective state and a broken state according to the pressure detection information.

[0061] Specifically, in this embodiment, the installation unit 1 also includes a fixing base arranged on the base to be installed, on which an installation assembly 10 is provided, and a counter is also provided. The counter is connected to the detection unit 2 and can count the number of components to be detected that are in a completely intact state, a semi-defective state, and a broken state according to the pressure detection information.

[0062] In this embodiment, by adding a fixed seat on the basis to be installed and providing an installation component 10 on the fixed seat, the present application achieves a stable installation and precise positioning of the detection unit 2, ensures accurate contact between the pressure detection component 202 and the component to be detected (tool), thereby improving the accuracy and stability of broken tool detection.

[0063] The counter introduced in this embodiment adds data analysis and management capabilities to the detection structure. The counter is closely connected to the detection unit 2 and can automatically count the number of tools in a completely intact state, a semi-defective state, and a broken state according to the pressure detection information.

[0064] The counter can display the number of tools in each state in real time. Once the tool is detected to be broken, an early warning will be issued immediately (the counter is connected to the detection unit and the control unit respectively) to prevent possible processing failures and safety accidents. At the same time, for tools in a semi-defective state, the statistics of the counter can also remind the operator to carry out necessary inspections and repairs, extend the service life of the tool, and reduce unplanned downtime.

[0065] By collecting and analyzing the data from the counter, the pattern and frequency of tool damage can be identified, providing data support for improving the machining process, selecting more durable tool materials, or optimizing the tool replacement cycle. This helps reduce tool replacement costs, improves machining efficiency, and also provides a reference for optimizing machine tool performance.

[0066] The statistical results of the counter can be used to formulate predictive maintenance strategies. For example, when the number of semi-defective tools is detected to be gradually increasing, the inspection and replacement of the tools can be arranged in advance to avoid unexpected downtime caused by sudden tool breakage. This data-driven maintenance model can significantly improve the operating efficiency and reliability of machine tools and reduce maintenance costs.

[0067] The data from the counter can be connected to the tool inventory system of the machine tool to automatically update the tool inventory information, including the number of complete tools, tools to be repaired, and scrapped tools. This helps to achieve refined management and dynamic adjustment of tool inventory, ensuring that the machine tool can quickly obtain suitable tools when needed, while avoiding problems caused by excessive inventory or shortage of tools.

[0068] Furthermore, the mounting assembly 10 comprises: a first mounting plate 101, on which a plurality of first locking holes 102 arranged along a first direction are provided;

[0069] A fixing seat, on which a plurality of second locking holes are arranged, and the plurality of second locking holes are arranged one-to-one correspondingly to the plurality of first locking holes 102;

[0070] A plurality of first locking components correspond to the plurality of first locking holes 102 one by one, so as to penetrate through the first locking holes 102 and the second locking holes, and fix the mounting assembly 10 on the fixing seat through the first mounting plate 101 .

[0071] Specifically, in this embodiment, the mounting assembly includes a first mounting plate 101, and a plurality of first locking holes 102 are provided on the first mounting plate 101, and the plurality of first locking holes 102 are arranged along a first direction, and the first direction is the length direction of the first mounting plate 101, and a plurality of second locking holes are opened at corresponding positions on the fixing seat, and the plurality of second locking holes are arranged one by one with the plurality of first locking holes 102, and also includes a first locking component for being inserted between the plurality of first locking holes 102 and the plurality of second locking holes, so as to fix the mounting assembly 10 on the fixing seat through the first locking component, wherein the first locking component is a locking bolt in this embodiment.

[0072] In this embodiment, the design of the mounting assembly further optimizes the installation process and the flexibility of use of the broken knife detection mechanism. By providing a plurality of first locking holes 102 on the first mounting plate 101 and arranging them in a one-to-one correspondence with the second locking holes on the fixing seat, the present design achieves a fast, accurate and stable installation of the detection unit 2. The use of the first locking component (such as a locking bolt) not only simplifies the installation process, but also ensures a reliable connection between the detection unit and the machine tool structure, providing a solid foundation for subsequent broken knife detection.

[0073] The matching design of the first locking hole 102 on the first mounting plate 101 and the second locking hole on the fixing seat makes the installation and removal of the detection unit 2 extremely convenient. The operator only needs to loosen or tighten the locking bolt to complete the installation or removal of the detection unit 2, which greatly saves maintenance and debugging time and improves the operation efficiency of the machine tool.

[0074] To sum up, the installation component design in this embodiment, through the coordinated use of the first locking hole 102, the second locking hole and the locking bolt, not only simplifies the installation process of the detection unit 2, improves the stability and accuracy of the installation, but also enhances the adaptability and maintenance convenience of the detection structure, and has significant technical effects on ensuring the processing quality and operation safety of CNC machine tools and improving processing efficiency.

[0075] Furthermore, the mounting assembly 10 further includes: a second mounting plate 103, the extension direction of the second mounting plate 103 is perpendicular to the first mounting plate 101, and the second mounting plate 103 has a first mounting surface;

[0076] The second mounting plate 103 is provided with a plurality of third locking holes, the fixing seat is provided with a plurality of fourth locking holes, and the plurality of fourth locking holes are provided in a one-to-one correspondence with the plurality of third locking members;

[0077] The plurality of second locking components correspond one-to-one with the plurality of third locking holes, so as to penetrate the third locking holes and the fourth locking holes, and fix the mounting assembly 10 on the fixing seat through the second mounting plate 103 .

[0078] Specifically, the mounting assembly 10 includes a second mounting plate 103, which is perpendicular to the first mounting plate 101 and is L-shaped. The second mounting plate 103 has a first mounting surface, wherein a plurality of third locking holes are provided on the second mounting plate 103, and a fourth locking hole is provided at a position corresponding to the plurality of third locking holes on the fixed seat. The second mounting plate 103 also includes a plurality of second locking components, and the plurality of second locking components correspond one-to-one to the plurality of third locking holes, so as to be inserted into the third locking holes and the corresponding fourth locking holes, so as to fix the mounting assembly 10 on the fixed seat through the second mounting plate 103.

[0079] In this embodiment, the design of the mounting assembly 10 further optimizes the installation process and the flexibility of use of the detection structure. By providing a plurality of first locking holes 102 on the first mounting plate 101 and a plurality of third locking holes on the second mounting plate 103, which correspond one-to-one with the second locking holes and the fourth locking holes on the fixing seat, the present design achieves a fast, accurate and stable installation of the detection unit 2. The use of the first locking component (such as a locking bolt) and the second locking component not only simplifies the installation process, but also ensures a reliable connection between the detection unit and the machine tool structure, providing a solid foundation for subsequent broken tool detection.

[0080] The L-shaped design of the first mounting plate 101 and the second mounting plate 103 not only provides multiple fixing points, but also increases the stability of the installation, ensuring that the detection unit can maintain a good working condition under various processing conditions.

[0081] Furthermore, the mounting assembly 10 further includes: a reinforcing rib 104, the reinforcing rib 104 being disposed on a side of the mounting assembly 10 away from the fixing seat, the reinforcing rib 104 being disposed between the first mounting plate 101 and the second mounting plate 103;

[0082] The fixing seat is provided with a reinforcement groove, the position and shape of which are matched with the reinforcement rib 104, and at least a part of the reinforcement rib 104 is located in the reinforcement groove.

[0083] Specifically, the mounting assembly 10 further includes a reinforcing rib 104 disposed on a side of the mounting assembly 10 away from the fixing seat. Figure 1 As shown, the reinforcing rib 104 is triangular in shape and is disposed between the first mounting plate 101 and the second mounting plate 103. A reinforcing groove is provided on the fixing seat, and at least part of the reinforcing rib is located in the reinforcing groove. The shape of the reinforcing groove matches the shape of the reinforcing rib.

[0084] The triangular reinforcing rib 104 design has natural stability and strength characteristics, which effectively enhances the connection strength between the first mounting plate 101 and the second mounting plate 103, and reduces the possibility of deformation or displacement under external force. This improvement in structural rigidity is crucial to ensure the stability and reliability of the detection unit 2 during the processing process.

[0085] The use of the reinforcing rib 104 in conjunction with the reinforcing groove can effectively suppress vibration caused by machine tool processing. When at least part of the reinforcing rib is embedded in the reinforcing groove, the close contact between the two can reduce the conduction of vibration, maintain the stability of the detection unit under high-speed processing conditions, and ensure that the accuracy of broken tool detection is not affected by vibration.

[0086] By increasing the overall rigidity of the mounting assembly and reducing vibration, the stability of the detection unit 2 during the broken tool detection process is significantly improved. This directly promotes the improvement of detection accuracy, allowing the pressure sensor to more accurately sense changes in the tool state, reducing false positives or missed positives, and improving the reliability and accuracy of broken tool detection.

[0087] In summary, the design of the reinforcing rib 104 in this embodiment, through its use in conjunction with the reinforcing groove, not only significantly improves the structural rigidity and stability of the mounting assembly 10, but also optimizes the vibration suppression effect of the detection unit 2, and effectively improves the accuracy and reliability of the broken tool detection. This design provides a significant technical effect for the broken tool detection technology of CNC machine tools, helps to improve processing quality and efficiency, and ensures operational safety.

[0088] Furthermore, the detection structure also includes: a display component, which is connected to the detection unit 2 and the control unit respectively, so as to display the completeness of the component to be detected in real time under the action of the control unit.

[0089] Specifically, the detection structure also includes a display component connected to the detection unit 2 and the control unit respectively, which can realize real-time display of the completeness of the components to be detected under the action of the control unit. Because the counter is connected to the detection unit, it can record the number of components to be detected in a completely complete state, the number of components to be detected in a semi-defective state, and the number of components to be detected in a broken state, so that the operator can observe in real time.

[0090] The addition of the display component enables the operator to monitor the broken tool detection status of the detection unit 2 in real time. This not only provides an intuitive display of the tool integrity, but also updates the tool status data recorded by the counter in real time, including the number of tools in a completely intact state, a semi-defective state, and a broken state. This real-time feedback mechanism enables the operator to quickly respond to changes in the tool status and take timely measures to prevent processing failures or safety risks caused by tool problems.

[0091] The display component visualizes the tool status numbers recorded by the counter, helping operators and maintenance personnel quickly understand the usage of machine tool tools. This intuitive presentation of data facilitates trend analysis, identification of tool damage patterns, and provides data support for tool replacement planning, machining parameter optimization, and equipment maintenance, thereby improving production efficiency and reducing maintenance costs.

[0092] Based on the tool status data provided by the display component, the operator can perform predictive maintenance, that is, before the tool enters a semi-defective or broken state, according to the quantity trend recorded by the counter, arrange tool inspection or replacement in advance, avoid unplanned downtime caused by sudden tool damage, reduce the risk of production interruption, and improve the operation stability and production efficiency of the machine tool.

[0093] The tool status and quantity information provided by the display component helps optimize tool inventory management. When the operator observes an increase in the number of semi-defective tools, the tool inventory can be replenished in time to avoid tool shortages; at the same time, for tools in a broken state, the warning function of the display component can remind the operator to take immediate measures to prevent waste of resources.

[0094] In summary, the addition of the display component in this embodiment, combined with its close connection with the detection unit 2 and the control unit, not only provides real-time feedback on the broken tool detection status, but also brings significant technical effects to the broken tool detection technology of CNC machine tools through data visualization, improved operation convenience, predictive maintenance, resource allocation optimization and enhanced safety. This innovative design helps to improve processing quality and efficiency, reduce maintenance costs, and ensure operational safety. It is an important progress in the field of broken tool detection of CNC machine tools in modern manufacturing.

[0095] Furthermore, the detection structure also includes: an alarm component, which is connected to the detection unit 2 and the control unit respectively, so as to issue an alarm warning under the control of the control unit according to the pressure detection information of the detection unit 2.

[0096] Specifically, the detection structure also includes an alarm component connected to the detection unit 2 and the control unit respectively. The alarm component can issue an alarm under the control of the control unit based on the pressure detection information of the detection unit 2 to alert the staff. When the component to be detected is in a broken state or the number of components to be detected in a broken state exceeds a set threshold, an alarm will be issued to control the machine tool to stop running and carry out maintenance and other work in time.

[0097] The alarm component can judge the tool status in real time based on the pressure detection information sent by the detection unit 2 under the intelligent analysis of the control unit. When it is detected that the tool is broken or damaged to reach the preset threshold, the alarm is triggered immediately, and the operator is quickly notified through sound, light or other warning signals. This instant response mechanism enables the operator to take measures at the first time to avoid production accidents or machine tool damage caused by tool problems.

[0098] The linkage between the alarm component and the control unit enables the machine tool to automatically stop when a broken tool is detected. This intelligent control not only reduces the delay of manual intervention, but also prevents the broken tool from further damaging the workpiece by immediately stopping the processing activity, protects other parts of the machine tool from damage, and significantly improves the safety of the processing process.

[0099] Through immediate response and early warning, operators can quickly identify and solve the tool breakage problem, avoiding long production interruptions. In addition, preventive maintenance can keep the machine tool in good operating condition, reduce the decline in production efficiency caused by equipment failure, and thus improve production efficiency and processing quality overall.

[0100] In summary, the addition of the alarm component in this embodiment, combined with its intelligent connection with the detection unit 2 and the control unit, not only realizes instant tool breakage warning and intelligent machine control, but also brings significant technical effects to the tool breakage detection technology of CNC machine tools through preventive maintenance, production efficiency improvement, operator safety protection and resource optimization. This innovative design helps to improve processing quality and safety and reduce maintenance costs.

[0101] The present application also provides a machine tool, which is provided with a tool magazine and a detection structure for detecting the tools in the tool magazine, wherein the detection structure is the detection structure mentioned above, the machine tool is the base to be installed mentioned above, and the component to be detected is the tool.

[0102] The present application also provides a detection method, which is applicable to the above-mentioned detection structure, and the detection method includes:

[0103] S1, control the part to be inspected to rotate to the station to be inspected;

[0104] S2, when it is determined that the component to be detected is at the position to be detected, the detection end of the pressure detection component 202 in the detection unit 2 is controlled to move in a direction close to the component to be detected so as to contact with at least part of the component to be detected, and generate corresponding pressure detection information;

[0105] S3, when it is determined that the pressure detection information of the pressure detection component 202 is equal to the first set threshold, it indicates that the component to be detected is in a completely intact state;

[0106] When it is determined that the pressure detection information of the pressure detection component 202 is less than the first set threshold and greater than the second set threshold, it indicates that the component to be detected is in a semi-defective state;

[0107] When it is determined that the pressure detection information of the pressure detection component 202 is less than the second set threshold, it indicates that the component to be detected is in a fracture state;

[0108] Among them, the degree of completeness includes completely complete state, semi-defective state, and broken state.

[0109] like Figure 2 As shown, the present application also provides a detection method, which is applicable to the above-mentioned detection structure. The detection method includes controlling one or a group of tools in the tool magazine to make circumferential motion. When the tool to be detected rotates to the station to be detected, the detection end of the pressure detection component 202 in the detection unit 2 is controlled to move in the direction close to the tool to be detected, and abuts against the tool to be detected to generate a corresponding pressure detection signal. When it is judged that the pressure detection signal is equal to the first set threshold, it indicates that the currently detected tool is in a completely intact state. If it is judged that the pressure detection signal is less than the first set threshold and greater than the second set threshold, it indicates that the currently detected tool has certain defects, but this defect is in a repairable state. When it is judged that the pressure detection signal is less than the second set threshold, it indicates that the detection end of the pressure detection component 202 cannot contact the component to be detected, which indicates that the currently detected tool is in a broken state.

[0110] The detection method distinguishes different states of the tool by setting a first set threshold and a second set threshold. When the pressure detection signal is equal to the first set threshold, the tool is judged to be in a completely intact state, ensuring the effective use of the tool; when the signal is less than the first set threshold but greater than the second set threshold, the tool is judged to have a repairable defect, thereby giving an early warning to avoid a decrease in processing quality; and when the signal is less than the second set threshold, the tool is confirmed to be broken and an alarm is triggered immediately.

[0111] Through the automated detection process, the method greatly improves the efficiency of broken tool detection. When the tools in the tool magazine are moving in a circular motion, the detection unit 2 can automatically complete the detection of each tool without manual intervention, reducing production delays caused by manual inspection of tool status, while ensuring the quality control of the processing process and avoiding the scrapping of workpieces due to the use of damaged tools.

[0112] To sum up, the detection method proposed in this application, through an automated and intelligent detection process, combined with threshold judgment and linkage control, not only improves the efficiency and accuracy of broken tool detection in CNC machine tools, but also realizes preventive maintenance, production quality control, safety protection and resource optimization, and has significant technical effects on improving the operating stability and production efficiency of CNC machine tools.
